Detailed Description
The following describes in further detail the embodiments of the present invention with reference to the drawings and examples. The following examples are illustrative of the invention and are not intended to limit the scope of the invention.
The linear motor controller structure 10 for the sliding door comprises a shell 113 and multi-layer structure circuit boards 1 and 2 arranged in the shell 113, wherein a certain interval is arranged between adjacent layers of circuit boards 1 and 2.
The circuit boards 1,2 are arranged at intervals, and part of the electronic components 11 can be arranged at intervals and other positions of the circuit boards 1, 2. Therefore, the components formed by the circuit boards are compactly arranged, the whole length of the controller 10 is greatly shortened, the length occupied by the controller 10 in the installation section is saved, enough space is left in the installation section for placing the stator and other components, and the adaptability of the linear motor control structure for the sliding door to different widths and different stroke door bodies is enhanced. In addition, the assembly of the linear motor for the sliding door is generally operated in a mode that the assembly is sequentially connected and plugged into the mounting section, and the small-length controller is beneficial to the mounting and replacement of the controller by an installer.
In order that the above objects, features and advantages of the invention will be readily understood, a more particular description of the invention will be rendered by reference to specific embodiments thereof which are illustrated in the appended drawings.
As shown in fig. 1, the controller 10 in this embodiment has an outer housing 113, and the housing 113 is formed with an interior for accommodating various components, mainly a multilayer circuit board and electronic components soldered on the circuit board.
Preferably, in the present embodiment, the number of specific circuit boards of the multi-layer structure is two, as shown in fig. 2, namely, a first layer circuit board 1 and a second layer circuit board 2. The first layer circuit board 1 is parallel to the second layer circuit board 2, and a certain distance is kept between the first layer circuit board and the second layer circuit board.
It should be noted that the number of the circuit boards with the multi-layer structure can also be three or more than three layers according to the design height of the controller, and a certain distance is formed between each two adjacent layers of circuit boards. The technical scheme is similar to the embodiment, and the technical effects of the invention can be realized.
Further, in order to keep a certain interval between the first layer circuit board 1 and the second layer circuit board 2, a spacer 12 is provided between the first layer circuit board 1 and the second layer circuit board 2. The spacer 12 effectively ensures that the space between the circuit boards in the multilayer structure is stable and stabilizes the circuit boards in each layer.
Further, as shown in fig. 2 and 5, an insulating cover 13 is provided on the first layer circuit board 1, and a power element (not shown) is provided in the insulating cover 13 for improving the heat dissipation capability of the power element. The insulating sleeve 13 may be made of an existing insulating material, and in this embodiment, the insulating sleeve 13 is generally made into a square shape, or may take other shapes, which is not limited herein. Because the linear motor control structure for the sliding door has more electronic elements and limited space, the insulating sleeve is designed to be used for placing the power element under a multi-layer structure, and the heat emitted by the power element can be efficiently transferred to the outside through the insulating sleeve, so that the heat dissipation effect is good.
Further, in the present embodiment, the insulating cover and the type of the electronic component are specifically disposed at the positions of the first layer circuit board 1 and the second layer circuit board 2, so as to maximize the heat dissipation capability. Since the outer side of the multilayer circuit board, i.e. the surface of the control structure housing, is adjacent to the outside, the heat dissipation is faster here, and the insulating sleeve 13 and the power components placed therein are arranged on the outer side of the multilayer circuit board. And the non-power elements may be oppositely disposed at a location between the two layers of circuit boards.
Specifically, in the embodiment shown in fig. 2, the outer side surfaces are the lower surface of the first layer circuit board 1 and the upper surface of the 2 nd layer circuit board. In this embodiment, the insulating cover 13 is preferably provided on the lower surface of the first layer circuit board 1.
The power element has large heat productivity in the electronic element category, is arranged in the insulating sleeve 13 and is arranged on the outer side surface, so that the heat of the power element can be timely and effectively emitted, and the heat dissipation efficiency of the controller is greatly improved. The technical scheme provides an efficient heat dissipation means according to the multilayer structure of the circuit board.
Further, the insulating sheath 13 is in contact with the housing 113 adjacent thereto. The heat of the insulating jacket 13 is directly transferred out through the housing 113. Compared with the case of no contact, the direct heat conduction is improved in heat exchange efficiency and better in heat dissipation effect compared with the heat convection between the insulating sleeve 13 and the shell 113 through the air layer.
The spacer 12 of the present embodiment will be further described below. As shown in fig. 3, the spacer 12 has snap parts 121, 123 at both ends. Correspondingly, the first layer circuit board 1 and the second layer circuit board are provided with clamping holes 22, the clamping parts 121 are inserted into the clamping holes 22 of the second layer circuit board 2, and the clamping parts 123 are inserted into the clamping holes 22 of the first layer circuit board 1.
As shown in fig. 2, the spacer 12 and the card holes 22 are plural, and the card holes 22 are distributed on the first layer circuit board 1 and the second layer circuit board 2. The design of the plurality of spacers 12 and the clamping holes 22 enables different areas of the first layer circuit board 1 and the second layer circuit board 2 to be supported by the spacers 12, so that deformation of the two layers of circuit boards 1 and 2 can be avoided.
Further, intermediate the spacers 12 is a spacer block 122. In this embodiment, the spacer 122 is square. In other embodiments, the spacer 122 may be cylindrical or other shapes. The fastening portions 121 and 123 are respectively protruded on both end surfaces of the spacer 122, and the fastening portions 121 and 123 and the spacer 122 are preferably integrally formed. The projection area of the spacer 122 on the circuit board is larger than the area of the clamping hole 22 formed on the circuit board. This allows the spacer 122 to be caught between the first circuit board 1 and the second circuit board 2 without loosening. The spacer 122 ensures a force providing a sufficient space between the first layer circuit board 1 and the second layer circuit board 2, effectively ensuring the stability of the entire multilayer structure in this embodiment.
As shown in fig. 3 and 4, each of the engaging portions 121 and 123 has two elastic members 1211, and the left and right elastic members 1211 are disposed at opposite intervals on the end surface of the spacer 122. The outer end of the elastic member 1211 protrudes laterally outward to form a slide hook 1213. The inner end of the slide hook 1213 is the base of the elastic member 1211, the slide hook 1213 at the upper end has a slide surface 1212 inclined outwardly and downwardly, and the slide hook 1213 at the lower end has a slide surface 1212 inclined outwardly and upwardly. The elastic member 1211 is entirely mushroom-shaped. When the engaging portions 121 and 123 are engaged with the engaging hole 22, the slide surface 1212 abuts against the edge of the engaging hole 22, and the edge of the engaging hole 22 presses the slide surface 1212 in the middle, so that the two elastic members 1211 provided opposite to each other are elastically pressed against each other, and the slide hook 1213 slides into the engaging hole 22. After passing, the radius of the sliding hook 1213 of the cap and the cross-sectional area of the spacer 122 are large due to the smaller radius of the base, and the circuit board is clamped between the sliding hook 1213 and the spacer 122. The elastic member 1211 and the sliding hook 1213 facilitate the snap-in portion 121 to be snapped into the snap-in hole 22 of the circuit board, and also facilitate the detachment of the spacer 121 from the circuit board due to the elastic restoring ability of the elastic member 1211.
In this embodiment, the upper and lower ends of the spacer 122 and the elastic member 1211 may have different specific shapes. As shown in fig. 3 to 4, the upper elastic member 121 has a rectangular cross section, and the sliding surface 1212 of the sliding hook 1213 is formed as a flat surface. The cross section of the lower elastic member 121 is arc-shaped, and the sliding surface 1212 of the sliding hook 1213 is formed as a curved surface.
Further, a receiving groove 21 is also formed in the second layer circuit board 2. Since the height of the electronic component 11 such as a capacitor is high after soldering on the first layer circuit board 1, the interval between the two layers of circuit boards 1,2 may be exceeded. The preset accommodating groove 21 can be used for the electronic component 11 mounted on the first layer circuit board 1 to pass through, so that larger components can be smoothly arranged on the circuit board with the multilayer structure, and the whole circuit board still maintains a compact multilayer structure.
In addition, the controller 10 is also provided with connection terminals at both ends thereof, connected with a stator assembly (not shown) or the like. In this embodiment, the first connecting portion 111 and the second connecting portion 112 are specifically included, the first connecting portion 111 is welded at two ends of the first layer circuit board 1, the formed interface is electrically connected with other components, and the second connecting portion 112 is physically connected with other components. The whole multi-layer circuit board structure does not need to be provided with wires, the board surface is concise, and the integration level is high.
From what is illustrated in fig. 1,2 and 5, it can be directly and unambiguously derived that: the housing 113 has a long shape, and at least one end of the housing 113 in the longitudinal direction is opened. Referring specifically to the direction shown in fig. 2, it is clearly understood that the left end of the housing 113 is formed with an opening, and it is reasonably further understood that the right end of the housing 113 is also formed with an opening in conjunction with fig. 1 and 2. Based on the structure of the housing 113 shown in the drawings, when the controller is installed, the first layer of circuit board 1 and the second layer of circuit board 2 need to be connected and assembled through a plurality of spacers 12, and then the assembled circuit board structure is inserted into the housing 113 from one of the open ends of the housing 113.
The foregoing is merely a preferred embodiment of the present invention, and it should be noted that modifications and substitutions can be made by those skilled in the art without departing from the technical principles of the present invention, and these modifications and substitutions should also be considered as being within the scope of the present invention.
