The rotating shaft 1 includes a driving part 11 and a fixing part 12 , as shown in FIG. 5 , the two fixing parts 12 are respectively provided at two ends of the driving part 11 . The driving part 11 and the fixing part 12 can be obtained after subsequent processing on a circular shaft.

As shown in Fig. 3 and Fig. 6, the rotating assembly 2 can be configured to be composed of two parts. For example, the rotating assembly 2 is assembled from the front assembly 21 and the rear assembly 22 by clamping. The rotating assembly 2 can be arranged in a U-shape, a strip shape, an L-shape or a rectangle as a whole. The utility model takes the rotating assembly 2 as U-shaped as an example. Part of the fixing seat 3 is set in the U-shaped groove of the rotating assembly 2, and the rotating shaft 1 is set from top to bottom. The rotating assembly 2 is provided with a first mounting hole 20 along the up-down direction near the fixed seat 3 , and the fixing part 12 matches the first mounting hole 20 on the rotating assembly 2 . The top wire 23 is inserted from the side of the rotating assembly 2 close to the fixed seat 3 to squeeze the fixing part 12 into the first mounting hole 20, so as to fix the rotating shaft 1 in the rotating assembly 2, so that the rotating shaft 1 can be connected with the rotating assembly 2 Turn together.

The fixing base 3 includes a base 31 . The base 31 can be arranged in a T-shape as shown in FIG. 3 . The base 31 includes a casing 311 arranged horizontally and a mounting base 312 arranged vertically. The mounting base 312 is provided with a plurality of mounting holes, as shown in the figure, the mounting holes are arranged along the left and right directions. Multiple mounting holes are used to fix the entire hinge device 100 on a wall or a door frame. The base 31 can be integrally formed to improve the dimensional accuracy and aesthetics of the product. The housing 311 is provided with an accommodation chamber 311a, and the cross section of the accommodation chamber 311a can be set to be rectangular or the like (as shown in FIG. 6 , the accommodation chamber 311a is arranged to extend along the left-right direction of the housing 311 ). The rotating shaft 1 penetrates from one side wall of the housing chamber 311a, passes through the housing chamber 311a, and exits from the other side wall (as shown in Figure 6, penetrates from the upper chamber wall of the housing chamber 311a, passes through the housing chamber 311a's lower chamber wall passes through), and can rotate relative to the fixed seat 3. The base 31 can also be provided with a clamping plate 313 installed at one end of the housing 311 (as shown in FIG. 3 , the clamping plate 313 is installed at the right end of the housing 311 ).

Arranging the rotating shaft 1 as close as possible to the matching gap between the rotating assembly 2 and the fixing seat 3 improves the aesthetics of the door opening operation. The mounting base 312 and the rotating assembly 2 are not designed to be of equal thickness, that is, there is a drop H between the two along the thickness direction (front-back direction) of the hinge device 100 , as shown in FIG. 9 . The drop H forms an avoidance channel for the rubber strips. When the hinge device 100 is installed on the door body assembly, there is a matching gap between the door and the door frame, and usually the rubber strips need to be provided to cover it. Such setting can improve the aesthetics on the one hand, and on the other hand, when the door is set as a shower door, it can also prevent shower water from splashing through the joint gap between the two, so as to affect the cleanliness of the entire shower room. By setting the above-mentioned drop H, the rubber strip will not be interrupted by the hinge device 100, on the one hand, the installation of the rubber strip is simplified, and on the other hand, the sealing performance of the rubber strip (and the entire shower space) is improved.

wherein the top shaft enters the second mounting cavity from the inlet, and a portion of the top shaft passes out of the outlet.

5. The hinge assembly of claim 4, wherein the outer cylindrical wall of the carriage includes an annular recess.

6. The hinge assembly of any of claims 1 to 5, wherein the base includes a mount configured to secure the hinge assembly; the rotating assembly and the rotating shaft are positioned on the same side of the mounting seat; the mounting seat and the rotating assembly have a fall along the thickness direction of the hinge device, and the fall forms an avoiding channel.

7. The hinge assembly of any of claims 1 to 5, wherein the base further comprises:

a housing provided with an accommodating cavity; and

a chucking plate detachably mounted on the housing;

the shell and the clamping plate are enclosed to form the first mounting cavity; the other end of the reset element is abutted against the clamping plate.

8. The hinge device according to any one of claims 1 to 5, wherein the rotary shaft includes a stopper groove provided in a radial direction of the rotary shaft; the limiting groove is arranged as the driving part;

the limiting groove comprises a first abutting part, a second abutting part and a third abutting part which are sequentially connected along the circumferential direction; in an initial state of the hinge device, the second abutting portion abuts against the mating portion;

wherein the reset element drives the rotating shaft to reset from the first abutting part to the second abutting part; alternatively, the reset element drives the rotating shaft to reset from the third abutting portion to the second abutting portion.

9. The hinge device according to claim 8, wherein the second abutting portion is provided as a flat surface, and the first abutting portion is provided as an arc surface that is convex toward one side of the engaging portion.

10. A door assembly comprising a door frame, a moveable door body and a hinge assembly according to any one of claims 1 to 9;
