Specifically, as shown in fig. 3 to 7, in the present embodiment, the mounting base 1 and the display module 2 are substantially rectangular, but in other embodiments, other shapes may be adopted. The mounting cavity 11 is formed by being recessed in the front-back direction, the mounting base 1 is provided with an upper side wall 111, a lower side wall 112, a left side wall 113, a right side wall 114 and a rear wall 115 which form the mounting cavity 11, the mounting base 1 is further provided with an extending portion 14 which extends from the end portions of the upper side wall 111, the lower side wall 112, the left side wall 113 and the right side wall 114 to the periphery respectively, and the extending portion 14 is provided with a mounting surface 141 which is matched with the display module 2.

The inner wall of the right sidewall 114 is recessed rightward to form the fixing groove 15, and thus, the fixing groove 15 has a front inner wall, a rear inner wall, and a right inner wall forming itself, that is, the fixing groove 15 is formed by integrally recessing the inner wall of the right sidewall 114. In this embodiment, the guide surface 12 and the locking surface 13 are inner walls (i.e., front inner walls) of the fixing grooves 15 on the side close to the display module 2. Of course, in other embodiments, the fixing groove 15 may be formed by being recessed from other sidewalls.

In this embodiment, the mounting base 1 has a plurality of fixing grooves 15 spaced apart along the length direction of the right side wall 114, so that the fixing grooves 15 correspond to the latch arms 23 one to one, on one hand, when the display module 2 is assembled, the latch arms 23 correspond to the fixing grooves 15, thereby facilitating the installation and positioning, and on the other hand, the plurality of fixing grooves 15 spaced apart from each other provide better structural strength than directly forming a large fixing groove 15, thereby preventing the inner wall where the guide surface 12 and the latch surface 13 are located from being broken.

The mounting base 1 further has a retaining structure 16 disposed on an inner wall of one of the upper side wall 111, the lower side wall 112 and the left side wall 113, and the retaining structure 16 is a protrusion 161 protruding from the inner wall.

In this embodiment, the latching structure 16 is disposed on the inner wall of the left sidewall 113 so as to be opposite to the fixing groove 15. Consequently, the distance between structure 16 and the fixed slot 15 is held to the knot is the biggest, when the installation during display module 2, use hasp arm 23 as the fulcrum, the distance between structure 16 and the fixed slot 15 is then the arm of force to the knot, so, when the arm of force is the biggest, press display module 2 and hold structure 16 mutually fixed can make the interact power maximize between hasp arm 23 and the hasp face 13 with the knot, and then make the fixed more firm between display module 2 and the mount pad 1, and the clearance is littleer, reduce humid air and the risk that the condensation got into between display module 2 and the mount pad 1.

Specifically, the retaining structure 16 includes a recessed groove 162 recessed from the inner wall of the left side wall 113, a protruding rib 163 protruding from the inner wall of the recessed groove 162 to the installation cavity 11 and connected to the protrusion 161, the protrusion 161 protruding from the inner wall of the recessed groove 162 to the installation cavity 11 and connected to the upper and lower inner walls of the recessed groove 162, the protruding rib 163 extends along the front-back direction, and the protruding rib 163 further has a guide inclined surface 164 close to the display module 2.

In this embodiment, the left sidewall 113 is provided with a plurality of fastening structures 16 along its extending direction (up-down direction), and through the above arrangement, each protrusion 161 is disposed in the groove 162, and the upper and lower inner walls of the upper and lower connecting grooves 162 are further provided with the protruding rib 163 connecting the protrusions 161, so that the display module 2 and the fastening structures 16 are conveniently fixed to each other, and the protrusions 161 have higher structural strength and are not easily damaged.

Of course, in other embodiments, the protrusion 161 may be directly formed by protruding from the inner wall of the left sidewall 113, and may be disposed in multiple configurations, or may be disposed in a strip configuration, and to ensure a better fixing effect, the retaining structure 16 may also be disposed on the inner walls of the upper sidewall 111 and the lower sidewall 112.

The mounting base 1 also has a fool-proof portion 17 protruding further outward from the extension portion 14 to prevent the mounting base 1 from being mis-assembled. In this embodiment, the fool-proof portion 17 protrudes leftward from the left extension portion 14. This is because the display assembly of the present embodiment is mainly applied to the refrigerator 100 and is installed on the side liner of the refrigerator 100, so that, in order to facilitate the user to observe and adjust the display module 2, the display module 2 is generally disposed near the opening 102 side of the liner 101, and when the installation base 1 is reversely installed, the fool-proof portion 17 interferes with the front side of the side liner and cannot be installed, thereby reminding the installer to install again.

The mounting base 1 further has a pre-positioning member 18 installed in cooperation with the side bladder, the pre-positioning member 18 includes a first pre-positioning member 181 and a second pre-positioning member 182, the first pre-positioning member 181 protrudes from the mounting surface 141 to the display module 2, and is disposed near four corners of the mounting cavity 11, and is substantially "L" shaped, in this embodiment, the protruding length of the first pre-positioning member 181 is about 1-2mm, and the side bladder has a pre-positioning groove (not shown) in cooperation with the first pre-positioning member 181. The first pre-positioning element 181 and the pre-positioning slot mainly play a role in fixing. Of course, in other embodiments, in order to further enhance the fixing effect, a screw structure may be added.

The second pre-positioning element 182 is an elongated structure protruding forward from four sides of the mounting surface 141, and the side bladder has a pre-positioning hole (not shown) matching with the second pre-positioning element 182. This is because the installer cannot easily align the first pre-positioning member 181 with the pre-positioning slot by relying only on the first pre-positioning member 181 and because it is short.

Therefore, the second pre-positioning element 182 and the pre-positioning hole are installed first, the first pre-positioning element 181 is aligned with the pre-positioning groove, and the first pre-positioning element 181 is fastened into the pre-positioning groove by force to fix the pre-positioning groove. It should be noted that, when the display module 2 is installed, the second pre-positioning element 182 needs to be broken first and then installed.

As shown in fig. 3 to 5, the engagement structure of the display module 2 is formed to project rearward from the cover plate 21, and the latch arm 23 is formed to extend rightward from the right side of the extension wall 22 so as to be engaged with the fixing groove 15. In the present embodiment, in order to ensure sufficient holding force between latch arm 23 and latch face 13, it is necessary to ensure sufficient structural strength of extension wall 22 and latch arm 23 for support.

Specifically, the extension wall 22 is disposed in a strip shape along the vertical direction, and the matching structure has a plurality of latch arms 23 disposed on the extension wall 22 at intervals along the vertical direction, so that the extension wall 22 is an integral structure, relatively more firm, and not easy to break. Of course, in other embodiments, the matching structure may also have a plurality of extending walls 22 spaced apart from each other in the up-down direction, and each extending wall 22 is provided with one corresponding latch arm 23.

In order to ensure that the latch arm 23 is not easily broken, the wall thickness of the extension wall 22 at the position where the latch arm 23 is disposed is greater than the wall thickness of the extension wall 22 at the position where the latch arm 23 is not disposed, the matching mechanism further includes a reinforcing rib 231 disposed on the latch arm 23 and connected to the extension wall 22, the structural strength of the latch arm 23 is increased by increasing the wall thickness and the reinforcing rib 231, and the risk of breaking the latch arm 23 is greatly reduced while ensuring that sufficient resisting and holding force is provided between the latch arm 23 and the latch surface 13.

As shown in fig. 11, in order to enhance the holding force between the latch arms 23 and the latch surfaces 13, the ends of the latch arms 23 further have abutting portions 232 protruding toward the cover plate 21, and the abutting portions 232 elastically abut against the latch surfaces 13 when the display module 2 is mounted on the mounting base 1.

The matching structure further includes a fixing wall 24 extending backward from the cover plate 21, and a hook 241 protruding from the fixing wall 24, wherein the hook 241 is configured to match with the retaining structure 16 of the mounting base 1, so as to fix the display module 2 and the mounting base 1.

In this embodiment, the fixing wall 24 and the extending wall 22 are disposed opposite to each other, that is, the fixing wall 24 protrudes rearward from the left side of the cover plate 21, so that the distance between the fixing wall 24 and the extending wall 22 is the largest, that is, the force arm is the longest, when the display module 2 is mounted, the latch arms 23 are aligned with the fixing grooves 15 one by one, and then the left side of the display module 2 is pressed, so that the hooks 241 move rearward along the guiding inclined surfaces 164 of the protruding ribs 163 until the protrusions 161 are engaged with each other, at this time, the latch arms 23 serve as fulcrums, so that the supporting force between the latch arms 23 and the latch surfaces 13 is the largest, and the fixing effect between the display module 2 and the mounting base 1 is the best.

In this embodiment, the fixing wall 24 is similar to the extending wall 22 in structure, and has no strip-like structure extending in the up-down direction, but in other embodiments, a plurality of fixing walls may be arranged in the up-down direction.

In order to further strengthen the structural strength of the fixing wall 24 and the extending wall 22, the matching structure further includes a connecting wall 25 extending backward from the cover plate 21 and respectively connecting the extending wall 22 and the fixing wall 24, and the connecting wall 25 can support the extending wall 22 and the fixing wall 24 when the latch arm 23 and the latch 241 are elastically deformed, so as to reduce the risk of breaking.

In this embodiment, the fitting structure has two connecting walls 25 connected to the upper and lower sides of the extension wall 22 and the fixing wall 24, respectively. The fixed wall 24, the extension wall 22 and the connecting wall 25 are enclosed to form a rectangular frame structure, and are matched with the installation cavity 11. Gaps are formed between the outer edges of the periphery of the rectangular frame and the periphery of the cover plate 21 respectively.

The display module 2 further comprises a circuit board 26 arranged in the rectangular frame and a light-transmitting plate 27 located on the front side of the cover plate 21, a light source is arranged on the circuit board 26, the cover plate 21 is provided with a through hole 211 penetrating along the front-back direction, and the light source forms corresponding patterns through the through hole 211 to be displayed on the light-transmitting plate 27 so as to prompt a user.

As shown in fig. 1 and 2, the display assembly according to the embodiment of the present invention is mainly applied to a refrigerator 100, the refrigerator 100 includes a cabinet having an inner container 101, and a door body (not shown) engaged with the cabinet, the display assembly is disposed on the inner container 101, and the side container is located between the cover plate 21 and the mounting surface 141. In this embodiment, the display assembly is mainly disposed on a side of the inner container 101 and close to the opening 102 of the inner container 101, mainly for the convenience of observation and operation of a user. Of course, in other embodiments, the display assembly may be disposed at other positions of the inner container 101.

The inner container 101 is provided with a through hole penetrating along the transverse direction of the refrigerator 100, so that the display module 2 can be conveniently installed on the installation seat 1, and the size of the through hole is matched with the outer edge of a rectangular frame formed by enclosing the fixed wall 24, the extension wall 22 and the connecting wall 25, so that the risk that humid air and condensation in the refrigerator 100 enter the space between the display module 2 and the installation seat 1 through the through hole and the gap between the rectangular frame can be reduced.

And the cover plate 21 is larger than the size of the through hole, therefore, the periphery of the cover plate 21 is attached to the wall surface of the side liner, and the risk that humid air and condensation enter between the display module 2 and the mounting seat 1 can be further reduced.

In the present embodiment, the latch arm 23 and the latch surface 13 are both disposed at the front side along the front-back direction of the refrigerator 100, i.e. disposed near the opening 102, and in the embodiment of the display module, the latch arm 23 and the latch surface 13 are disposed at the right side of the cover plate 21 and the mounting base 1, respectively. Therefore, the bonding force between the side cover plate 21 and the wall surface of the side liner is larger, that is, the gap between the cover plate 21 and the wall surface of the side liner is smaller, and the gap is almost not existed in the view of actual products, so that the phenomenon of flash seam can be avoided, and the aesthetic degree is improved.

The flash seam means: when two objects cannot be closely attached, namely, a gap exists, the human eye cannot irradiate the gap along the observation angle of the human eye from the observation of the gap, so that a shadow or even a black area, namely a flash seam, exists in the gap during the actual observation. When the two are completely attached, the shadow or black area does not appear.

Therefore, in the display module of the refrigerator 100 of the embodiment, the cover plate 21 is tightly attached to the wall surface of the side liner, so that the occurrence of the flash seam on the side of the opening 102 can be avoided, and the risk of the humid air and the condensation entering the space between the display module 2 and the mounting seat 1 can be effectively reduced.

In summary, the mounting structure of the mounting base 1 of the refrigerator 100 and the display module of the present invention includes the guiding surface 12 extending obliquely from one side of the mounting cavity 11 toward a direction away from the cover plate 21 and the mounting cavity 11, and the locking surface 13 connected to the end of the guiding surface 12, the matching structure of the display module 2 includes the extending wall 22 extending from the rear side of the cover plate 21 toward the mounting cavity 11 beyond the locking surface 13, and the locking arm 23 extending obliquely from the end of the extending wall 22 toward the locking surface 13, and the locking arm 23 and the locking surface 13 are in abutting fit. Not only can strengthen fixed effect between mount pad 1 and the display module 2, can make moreover between mount pad 1 and the display module 2 laminate more, reduce humid air or condensation and get into the risk between mount pad 1 and the display module 2, guarantee that display module normally works, still can avoid the flash joint, improve pleasing to the eye degree.

Although the present invention has been described in detail with reference to the preferred embodiments, it will be understood by those skilled in the art that various changes may be made and equivalents may be substituted for elements thereof without departing from the spirit and scope of the present invention.
