[0035] To enable those skilled in the art to better understand the technical solution of the present utility model, the present utility model will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0036] Please refer to Figures 1 to 8 。

[0037] In a specific embodiment, the device mounting bracket provided by the specific embodiment of the present utility model includes a support frame 100 and a support plate 200. The support frame 100 is of a ring structure and is used for connecting the first connection position 10302 of the electrical component. The support frame 100 is sleeved on the outer periphery of the support plate 200 and is fixedly connected to the support plate 200. A convex rib 201 protruding away from the first connection position 10302 is formed by the concave inner surface of the plate surface of the support plate 200.

[0038] Specifically, the shapes of the convex ribs 201 may be the same or different. To improve the overall strength, preferably, the support plate 200 is provided with at least two different-shaped convex ribs 201. Specifically, the convex ribs 201 can be provided in various shapes. Specifically, different convex ribs 201 can be designed according to different design requirements (such as better bending resistance, compressive resistance, torsional resistance, different lengths, widths and heights of the PCB bottom plate, etc.). Specifically, during processing, the length, width and height of the device mounting bracket are deformed and designed according to the structure of the PCB.

[0039] During specific processing, the height of the convex rib 201 is set as required to meet the requirements of different installation structures.

[0040] The cross-sectional area of the groove formed by the convex rib 201 gradually decreases in the direction away from the first connection position 10302. As Figure 6 shown, the cross-sectional area of the convex rib 201 gradually decreases downward.

[0041] It can be seen from the above description that in the device mounting bracket provided by the specific embodiment of the present application, the convex rib 201 protruding away from the first connection position 10302 is formed by the concave inner surface of the plate surface of the support plate 200, and the overall strength of the support plate 200 is relatively high.

[0042] The support frame 100 surrounds the outer periphery of the support plate 200. The support frame 100 is limited by the support plate 200, so that the relative positions of the electrical components installed at the first connection position 10302 are stable. Therefore, the device mounting bracket provided by the present application improves the installation stability of the electrical components.

[0043] In a specific embodiment, the support plate 200 is of a stamping structure. That is, the support plate 200 adopts a ribbed structure and is formed by stamping. It can form a relatively complex ribbed plate structure with a simple processing process, and the overall strength is relatively high.

[0044] Specifically, the edge position of the support plate 200 can be an annular flat plate support 202 to facilitate connection with the support frame 100. When stamping the support plate 200, the flat plate support 202 is pressed, and raised ribs 201 are formed inside by stamping.

[0045] In a specific embodiment, the bottom plate and the upper support frame 100 are connected by welding. Specifically, the support frame 100 is welded to the upper surface of the flat plate support 202.

[0046] To improve the assembly efficiency and accuracy, preferably, the support frame 100 and the support plate 200 are integrally formed by stamping. That is, through the stamping action, the bottom plate and the frame structure are formed at one time.

[0047] As Figure 5 shown, in a specific embodiment, there are multiple raised ribs 201, and the raised ribs 201 are symmetrically arranged along the center line in the width direction of the support plate 200. At this time, the support plate 200 can be arranged in a rectangular shape. Specifically, the raised ribs 201 are arranged in an even number, and the shapes of each raised rib 201 can be completely the same or partially the same.

[0048] As Figure 5 shown, in a specific embodiment, there are multiple raised ribs 201, and the raised ribs 201 are symmetrically arranged along the center line in the length direction of the support plate 200. As described above, the raised ribs 201 are preferably arranged in an even number, and the shapes of each raised rib 201 can be completely the same or partially the same.

[0049] In a specific embodiment, the raised ribs 201 are symmetrically arranged along both the center line in the width direction of the support plate 200 and the center line in the length direction of the support plate 200. In this way, all the raised ribs 201 are arranged with the midpoint of the support plate 200 as the center of symmetry. Through the above arrangement, the overall strength of the support plate 200 is improved.

[0050] In a specific embodiment, the support frame 100 includes a first connection ring 101 and a second connection ring 102. Among them, both the first connection ring 101 and the second connection ring 102 are arranged in a ring shape. Specifically, the shapes of the first connection ring 101 and the second connection ring 102 are determined according to the shape of the support plate 200. Specifically, the shapes of the first connection ring 101 and the second connection ring 102 are the same as the shape of the support plate 200.

[0051] When the outer periphery of the support plate 200 is annular, the shapes of the first connection ring 101 and the second connection ring 102 are annular. When the outer periphery of the support plate 200 is rectangular, the shapes of the first connection ring 101 and the second connection ring 102 are rectangular.

[0052] As Figure 5As shown, a second connection position 10101 for installing a device mounting bracket is provided on the first annular surface 10102 of the first connection ring 101. Specifically, the second connection position 10101 can be a mounting hole provided on the first connection ring 101. Specifically, the device mounting bracket is firmly connected to other components through a fastener installed at the position of the second connection position 10101. Among them, the fastener can be a bolt. At this time, the mounting holes are arranged circumferentially around the first connection ring 101.

[0053] The first connection ring 101 is sleeved on the outer periphery of the second connection ring 102, and the second connection ring 102 is sleeved on the outer periphery of the support plate 200. Specifically, the first connection ring 101 and the second connection ring 102 can be connected by means such as bonding or welding. To improve the assembly efficiency, preferably, the first connection ring 101 and the second connection ring 102 are integrally formed structures. Specifically, both the first connection ring 101 and the second connection ring 102 are annular structures with the same thickness.

[0054] As Figures 6 to 8 shown, the support frame 100 further includes a third connection ring 103 arranged in a ring shape. The third connection ring 103 is installed on the end surface of the support plate 200 on the same side as the first annular surface 10102; the second connection ring 102 is sleeved on the outer periphery of the third connection ring 103 and is fixedly connected to the third connection ring 103; a first connection position 10302 for connecting electrical components is formed on the third annular surface 10301 of the third connection ring 103 on the same side as the first annular surface 10102.

[0055] To improve the assembly efficiency, preferably, the third connection ring 103 and the support plate 200 are integrally formed. During specific use, according to needs, by performing hole opening processing on the third connection ring 103, it is convenient for bolt installation to realize the fixation of electrical components. Or the electrical components are installed on the third annular surface 10301 of the third connection ring 103 by bonding. With such a setting, the thickness at the installation position of the electrical components increases, the deformation decreases, the processing and assembly errors are reduced, and the work efficiency can be improved.

[0056] As Figures 6 to 8 shown, the second connection ring 102 is provided with a second annular surface 10201 on the same side as the first annular surface 10102. The second annular surface 10201 protrudes from the first annular surface 10102. The second connection ring 102 and the support plate 200 enclose a potting space. Through the formation of the potting space in this application, it can be used for the PCB potting process, which is beneficial to the fixation of electronic components on the PCB board installed on the support bracket and improves the heat dissipation capacity of the electronic components.

[0057] The third annular surface 10301 is connected to the inner ring surface of the second connection ring 102, that is, during potting, the connection position of the electrical components can be further fixed by potting, thereby further improving the installation stability of the electrical components.

[0058] As can be seen from the above description, for the device mounting bracket provided by the application, through the all-round covering design of the electrical device, the support frame 100 is arranged in a stepped shape, so that the electrical device, such as a PCB board, is easy to position and has a certain axial stiffness.

[0059] To improve the installation stability of the electrical device, preferably, the outer periphery of the electrical device fits with the inner ring surface of the second connecting ring 102, that is, the electrical device is limited by the second connecting ring 102.

[0060] When the application is used for mounting a PCB board, it can provide better stiffness without changing the structure of the original PCB board, improve the vibration resistance of the PCB board, and avoid the situation that the support columns of the PCB board are broken during installation.

[0061] A motor controller assembly provided by the application includes a device mounting bracket and a PCB board mounted on the device mounting bracket, wherein the device mounting bracket is any of the above-mentioned device mounting brackets. The specific structure of the device mounting bracket has been described above. The application includes the above-mentioned device mounting bracket and also has the above-mentioned technical effects. Specifically, the motor controller assembly can be used for an engine.

[0062] The various embodiments in this specification are described in a progressive manner. Each embodiment focuses on the differences from other embodiments. The same or similar parts among the various embodiments can be referred to each other.
