Description

Technical Field

[0001] The utility model relates to an electrical device, in particular to a driving power supply. Background Art

[0002] Most electrical appliances have a power supply installed inside them, which needs to be connected to the mains. Therefore, leakage grounding protection for the power supply is crucial. The power supply housing is a metal enclosure, and to facilitate the installation of internal electrical components, the enclosure is a split structure. Existing enclosure grounding structures typically connect one portion of the enclosure to the ground wire, while the other separate parts of the enclosure are connected through connections between the enclosure parts. If there are gaps or loose connections between the enclosure parts, the grounding effect will be poor, posing a safety hazard. Some enclosures install separate grounding wires in each part of the enclosure, making assembly very cumbersome. Utility Model Content

DETAILED DESCRIPTION

[0023] The following describes in detail embodiments of the present invention, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to explain the present invention, and should not be construed as limiting the present invention.

[0024] The utility model relates to a driving power supply, which comprises an upper shell 100, a lower shell 200 and a circuit board 400.

[0025] like Figure 1 As shown, the upper shell 100 is connected to the lower shell 200, and the upper shell 100 and the lower shell 200 form a box-shaped structure. An installation cavity 300 is defined between the upper shell 100 and the lower shell 200. The upper shell 100 is provided with a connecting bar 110, and the material of the connecting bar 110 is a conductive material. For example, the upper shell 100 and the lower shell 200 are aluminum alloy shells, and the connecting bar 110 is integrally formed on the upper shell 100. The connecting bar 110 can be directly formed on the upper shell 100 as a part of the upper shell 100. A plurality of electrical modules such as power modules, drive modules, etc. can be arranged on the circuit board 400. The circuit board 400 is provided with a grounding terminal 410, and the grounding terminal 410 is grounded using a wire or the like. The circuit board 400 is placed in the installation cavity 300, and the connecting bar 110 extends toward the grounding terminal 410. Mounting holes can be provided on both the connecting bar 110 and the lower housing 200. The circuit board 400 is placed in the mounting cavity 300, with the mounting holes of the connecting bar 110 and the lower housing 200 aligned with the ground terminal 410. A locking member 500 is then inserted through the mounting holes of the connecting bar 110, the lower housing 200, and the ground terminal 410, locking the three together. The locking member 500 is also made of a conductive material and can be made of bolts, rivets, etc., with bolts being preferred. With the above structure, on the one hand, the relative positions of the upper shell 100, the lower shell 200 and the circuit board 400 can be fixed to ensure that the three will not move relative to each other. On the other hand, the lower shell 200 and the grounding end 410, as well as the connecting bar 110 and the grounding end 410 can be fully contacted to ensure the grounding stability of the upper shell 100 and the lower shell 200, thereby ensuring the power safety of the driving power supply, and completely eliminating the safety hazard of one of the upper shell 100 and the lower shell 200 being unable to be stably grounded due to poor contact or other reasons.

[0026] The connection structure between the upper shell 100 and the lower shell 200 is not limited and can be achieved by buckling, covering, etc. In some embodiments of the present invention, the upper shell 100 and the lower shell 200 are connected by sliding along the length direction. In the direction shown in the figure, the length direction of the upper shell 100 and the lower shell 200 is the left-right direction, and the upper shell 100 is slid from left to right to the upper part of the lower shell 200. After sliding connection, the upper shell 100 and the lower shell 200 cannot be separated in the up and down directions, and then the locking member 500 is used to pass through the connecting strip 110, the grounding terminal 410 and the lower shell 200, so that the upper shell 100 and the lower shell 200 are relatively locked and fixed in the length direction. The sliding connection structure of the upper shell 100 and the lower shell 200 can be a slot sliding connection, or a guide rail sliding connection, etc.

[0027] Specifically, such as Figure 2 and Figure 3 As shown, the lower shell 200 includes a first side panel 210, a second side panel 220, and a third side panel 230. In the direction shown in the figure, the first side panel 210 is in a flat position, and the thickness direction of the first side panel 210 is the up-down direction. The second side panel 220 and the third side panel 230 extend upward from the front and rear edges of the first side panel 210. The first side panel 210, the second side panel 220, and the third side panel 230 can be formed by bending a metal sheet. The opposing surfaces of the second side panel 220 and the third side panel 230 are provided with a clip 201 extending left and right along the length direction. The upper shell 100 can be set as a plate structure. The front and rear sides of the upper shell 100 are provided with a slide groove 120, with the front notch facing forward and the rear notch facing backward. The slide groove 120 extends along the length direction of the upper shell 100. The clip 201 on the second side panel 220 slides in engagement with the slide groove 120 on the front side of the upper shell 100, while the clip 201 on the third side panel 230 slides in engagement with the slide groove 120 on the rear side of the upper shell 100. When the upper shell 100 is slidably attached to the lower shell 200, the upper shell 100 can be adjusted forward and backward based on the installation positions of the connecting strip 110, the grounding terminal 410, and the lower shell 200.

[0028] In some embodiments of the present invention, the upper shell 100 and the lower shell 200 can be connected by a connecting bar 110. Alternatively, connecting bars 110 can be provided on a set of opposing sides of the upper shell 100 adjacent to the slide slot 120. In the illustrated orientation, if the slide slots 120 are provided on the front and rear sides of the upper shell 100, connecting bars 110 can be provided on the left and right sides of the upper shell 100. A grounding terminal 410 is located on the left side of the circuit board 400. The left connecting bar 110 is connected to the lower shell 200 and the grounding terminal 410 via a locking member 500, providing grounding for the upper shell 100. The right connecting bar 110 is locked to the right side of the circuit board 400 and the lower shell 200 via a locking member 500. The two connecting bars 110 work together to secure the left and right sides of the upper shell 100 and the left and right sides of the circuit board 400 to the lower shell 200.

[0029] Among them, such as Figure 1 As shown, the mounting cavity 300 is open at both ends along the length of the lower housing 200. The left and right ends of the mounting cavity 300 are open. The circuit board 400 is inserted into the mounting cavity 300 from one end, with the connecting bar 110 intercepting the opening of the mounting cavity 300 from top to bottom. Before installing the locking member 500, the connecting bar 110 can be used to pre-position the circuit board 400 in the left-right direction.

[0030] In some specific embodiments of the present invention, Figure 1 and Figure 2 As shown, the upper shell 100 has hems 130 on a set of opposing sides adjacent to the chute 120. As shown, the hems 130 are provided on both the left and right sides of the upper shell 100, and are bent downward toward the first side panel 210. The connecting strip 110 extends from the hems 130. The connecting strip 110 and the hems 130 can be formed by stamping and bending the upper shell 100.

[0031] The upper shell 100 is provided with a plurality of heat dissipation slots 140 . The heat dissipation slots 140 connect the mounting cavity 300 upward to the external environment, thereby improving the heat dissipation effect of the mounting cavity 300 .
