[0022] The specific embodiments of this disclosure will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit this disclosure.

[0023] In this disclosure, unless otherwise stated, directional terms such as "inner" and "outer" are defined in relation to the outline of the corresponding components. The terms "first," "second," etc., are used to distinguish different components and are not sequential or significant. Furthermore, in the following description, when referring to the accompanying drawings, unless otherwise explained, the same reference numerals in different drawings denote the same or similar elements.

[0024] According to one embodiment of this disclosure, such as Figure 1 As shown, a mounting bracket for a switching power supply is provided, including a first mounting plate 1 and a second mounting plate 2. The first mounting plate 1 is used to connect to a wall surface to be mounted. The second mounting plate 2 can be connected to one end of the first mounting plate 1 and forms an angle with the first mounting plate 1. Here, the angle between the first mounting plate 1 and the second mounting plate 2 can be between 80° and 100°, specifically 90°, which is not limited in this disclosure. The second mounting plate 2 includes multiple sets of mounting holes 20 spaced apart along a first direction for mounting the switching power supply. Each set of mounting holes 20 includes two mounting holes 21 spaced apart along a second direction, wherein the distance between the two mounting holes 21 in each set of mounting holes 20 is different.

[0025] Through the above technical solution, multiple sets of mounting holes 20 with different hole spacings are provided on the second mounting plate 2, so as to achieve the effect of a single bracket adapting to a variety of switching power supplies of different sizes, improve the versatility of the fixed bracket, reduce the variety of fixed bracket storage parts and the cumbersome selection of parts during construction, and also reduce manufacturing and management costs.

[0026] It should be noted that, to balance the compatibility of the fixing bracket and the strength of the second mounting plate 2, the number of mounting hole groups 20 can be set to three groups, and the distance between two mounting holes 21 in the three groups of mounting hole groups 20 can be 38mm, 50mm, and 60mm, respectively. The distance between two mounting holes 21 in the mounting hole group 20 can also be set to other distances as needed, and this disclosure does not limit this. In addition, to improve the installation strength of the first mounting plate 1 and the second mounting plate 2, the first mounting plate 1 and the second mounting plate 2 can also be integrally formed structures, and this disclosure does not limit this.

[0027] Furthermore, such as Figure 1As shown, in two adjacent sets of assembly hole groups 20, the distance between two assembly holes 21 in the first direction gradually increases. Here, the distance between two assembly holes 21 in the assembly hole group 20 can increase from the side closer to the first mounting plate 1 to the side farther away from the first mounting plate 1, or it can increase from the side farther away from the first mounting plate 1 to the side closer to the first mounting plate 1; this disclosure does not limit this. In this way, the hole spacing of the assembly hole groups 20 can be linearly arranged to form a gradient layout, allowing installers to quickly locate the hole group matching the power bolt position by visual inspection, reducing hole selection time.

[0028] According to one embodiment of this disclosure, such as Figure 1 As shown, in each group of mounting holes 20, one mounting hole 21 is a round hole, and the other mounting hole 21 is an oblong hole, extending along the second direction. The combination of the oblong hole and the round hole improves the tolerance. The round hole can be used for fixed reference positioning, while the oblong hole provides a certain length of installation tolerance in the second direction. This not only accommodates power supply mounting hole spacing not designed for the power supply, but also absorbs bending errors of the second mounting plate 2 and adapts to thermal expansion and contraction of the power supply housing. Here, the round hole can be 5mm in diameter, and the oblong hole can be a structure of two semicircles sandwiching a rectangle. The two semicircles are 5mm in diameter, and the distance between them is 4mm. Other dimensions can also be used as needed, and this disclosure does not limit this.

[0029] Regarding the mounting position of the assembly hole group 20 on the second mounting plate 2, the midpoint between the two assembly holes 21 in each assembly hole group 20 can be located on the central axis of the second mounting plate 2. This allows the switching power supply to be supported in the middle of the second mounting plate 2, which not only prevents its assembly from being skewed and affecting the subsequent assembly of other components, but also reduces the possibility of the bracket tipping over due to the assembly misalignment of the switching power supply, thus improving the stability of the switching power supply assembly.

[0030] According to one embodiment of this disclosure, such as Figure 1 As shown, the extension length of the first mounting plate 1 in the second direction can be greater than that of the second mounting plate 1 in the second direction. Specifically, the extension length of the first mounting plate 1 in the second direction can be 160 mm, and its width can be 27 mm. The extension length of the second mounting plate 2 in the second direction can be 90 mm, and its extension length in the first direction can be 47 mm. Two mounting holes 11 are provided at intervals along the second direction on the first mounting plate 1. Both mounting holes 11 are located on the outer side of the second mounting plate 2 in the second direction, that is, the distance between the two mounting holes 11 is greater than 90 mm, specifically, it can be 120 mm, to avoid interference with the switching power supply during installation.

[0031] Furthermore, the mounting hole 11 can be a gourd-shaped hole, with the large-diameter ends of the two gourd-shaped holes facing each other. The large hole diameter can be 10mm, and the small hole diameter can be 5mm. The two holes are joined together by cutting along the tangent of the small hole and the large hole. The line connecting the centers of the large hole and the small hole extends along the second direction, and the distance between the center of the large hole and the edge of the first mounting plate 1 in the second direction is 15mm, and the distance between the center of the small hole and the edge of the first mounting plate 1 in the second direction is 7.5mm. The small hole side of the gourd-shaped hole can provide a certain amount of movement space for the mounting bolt, which can improve the fault tolerance.

[0032] According to one embodiment of this disclosure, a chamfer can be provided at the connection between the first mounting plate 1 and the second mounting plate 2. The chamfer size can be a straight chamfer of 1mm x 45° or an arc chamfer to reduce the sharpness of the edges and prevent operators from being scratched.

[0033] The preferred embodiments of this disclosure have been described in detail above with reference to the accompanying drawings. However, this disclosure is not limited to the specific details of the above embodiments. Within the scope of the technical concept of this disclosure, various simple modifications can be made to the technical solutions of this disclosure, and these simple modifications all fall within the protection scope of this disclosure.

[0034] It should also be noted that the various specific technical features described in the above specific embodiments can be combined in any suitable manner without contradiction. In order to avoid unnecessary repetition, this disclosure will not describe the various possible combinations separately.

[0035] Furthermore, various different embodiments of this disclosure can be combined in any way, as long as they do not violate the spirit of this disclosure, they should also be regarded as the content disclosed in this disclosure.
