[0039] The present application will be further described in detail below with reference to the accompanying drawings and specific embodiments. The advantages and features of the present application will become more apparent from the following description. It should be noted that the drawings are all in a very simplified form and use non-precise ratios, and are only used to facilitate and clearly illustrate the embodiments of the present application.
[0040] It should be noted that all directional indications in the embodiments of the present application (such as up, down, left, right, front, back, etc.) are only used to explain the relative position relationship, movement status, etc. between the various components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.
[0041] Example 1
[0042] 1 to 8 , the core of the present application is to provide a power supply device 2, comprising a housing 4, a sun visor 15, a battery 5, and a stopper assembly. The sun visor 15 is provided on the top of the housing 4 to provide shade for the housing 4, and the battery 5 and the stopper assembly are both provided inside the housing 4. The stopper assembly is provided on the battery 5 to press the battery 5 against the inner wall of the housing 4, thereby securing the battery 5 within the housing 4 and ensuring contact heat transfer between the battery 5 and the housing 4.
[0043] The limiting assembly allows the battery 5 to rest against the inner wall of the housing 4, creating contact heat transfer between the battery 5 and the housing 4, thereby enhancing the heat dissipation effect of the battery 5. Heat from the battery 5 can be directly transferred to the housing 4. Furthermore, a sun visor 15 is provided on the top of the housing 4 to prevent direct sunlight from shining into the housing 4 during the day, thereby reducing the internal temperature of the housing 4 and increasing the service life of the battery 5. The sun visor 15 isolates heat while, in conjunction with the limiting assembly, holds the battery 5 in place against the inner wall of the housing 4, enhancing heat dissipation and maintaining a relatively comfortable temperature during operation.
[0044] Specifically, the battery 5 is mounted on the inner wall of the bottom of the box 4, and the limiting assembly presses the battery 5 against the inner wall of the bottom of the box 4. The top of the box 4 is provided with a mounting portion, and the sun visor 15 is mounted on the top of the box 4 through the mounting portion. The mounting portion creates a gap between the sun visor 15 and the top of the box 4, further enhancing the thermal insulation effect.
[0045] The mounting portion can be a ridge 16, onto which the sun visor 15 is screwed. Specifically, the ridge 16 projects upward and extends along the length of the housing 4. This structure allows the ridge 16 to be integrally formed with the housing 4 using a profile molding process, eliminating the need for additional mounting and fixing. The mounting portion can also be a first stud 19, onto which the sun visor 15 is screwed. Of course, in other embodiments, the mounting portion can also have other structures, which are not limited in this embodiment. In other embodiments, the sun visor 15 can also be fixed to both sides of the housing 4 or to the lamp post 1 using other components, which are not limited in this embodiment.
[0046] Referring to Figures 2 to 6, in the first scheme, the limiting assembly 6 includes a first limiting portion, a second limiting portion and an adjusting portion, the first limiting portion and the second limiting portion are movably connected, the adjusting portion is arranged between the first limiting portion and the second limiting portion, and the adjusting portion is used to adjust the relative position between the first limiting portion and the second limiting portion.
[0047] The battery 5 is disposed between a first inner wall and an opposing second inner wall within the housing 4. A stopper assembly 6 is disposed between the battery 5 and the first inner wall. The adjustment portion adjusts the relative position between the first and second stoppers so that the first stopper abuts the first inner wall and the second stopper abuts the battery 5, thereby pressing the battery 5 against the second inner wall. In this embodiment, the first inner wall is the inner wall at the top of the housing 4, and the second inner wall is the inner wall at the bottom of the housing 4.
[0048] Specifically, the first limiting portion is the first slider 7, and the second limiting portion is the second slider 9. The first slider 7 is provided with a first inclined surface, and the second slider 9 is provided with a second inclined surface corresponding to the first inclined surface. The first inclined surface is in contact with the second inclined surface, and the first slider 7 and the second slider 9 can slide obliquely relative to each other through the cooperation of the first inclined surface and the second inclined surface, so that the first slider 7 and the second slider 9 can move relative to each other in the horizontal and vertical directions. The horizontal direction is the direction between the two sides of the battery 5, and the longitudinal direction is the direction between the battery 5 and the first inner wall. The adjustment portion is used to drive the first slider 7 and the second slider 9 to slide obliquely relative to each other to adjust their relative positions.
[0049] The adjustment portion includes an adjustment bolt 14. The first slider 7 is provided with a receiving channel 8 along the longitudinal direction, and the receiving channel 8 extends transversely through the first slider 7. The second slider 9 is provided with a threaded hole. The adjustment bolt 14 extends transversely through the receiving channel 8 and is threadedly connected to the second slider 9 through the threaded hole. The head of the adjustment bolt 14 abuts a side wall of the first slider 7 away from the second slider 9. The adjustment bolt 14 extends transversely through the receiving channel 8 and is threadedly connected to the second slider 9. This allows the adjustment bolt 14 to drive the first slider 7 to slide diagonally while also limiting the position of the first slider 7, preventing separation between the first slider 7 and the second slider 9. Furthermore, because the receiving channel 8 is provided longitudinally, that is, it has a certain depth in the height direction, the first slider 7 will not interfere with the adjustment bolt 14 when the first slider 7 moves diagonally relative to the second slider 9.
[0050] Preferably, a nut 13 is fixed on the second slider 9, a threaded hole is provided on the nut 13, and the adjusting bolt 14 is passed through the second slider 9 and threadedly connected to the nut 13. Of course, in other embodiments, a threaded hole can also be directly opened on the second slider 9, which is not limited in this embodiment.
[0051] The limiting assembly 6 specifically includes a first slider 7, a second slider 9, an adjusting bolt 14 and a nut 13, and has a relatively simple structure and low cost.
[0052] The second slider 9 is provided with a stopper, which cooperates with the battery 5 to at least limit the second slider 9 from moving laterally away from the first slider 7. In this embodiment, the stopper is provided on the side of the second slider 9 that faces the first slider 7 in the laterally direction. The stopper abuts the side wall of the battery 5 on the side closest to the first slider 7 to limit the second slider 9 from moving laterally away from the first slider 7. This eliminates the need to drive screws into the second slider 9 for securing, making installation more convenient. The second slider 9 can be simply placed on the battery 5 with the stopper abutting the side wall of the battery 5.
[0053] Specifically, the second slider 9 is an integrally bent member, comprising two bent inclined plates 10 on either side, a bent end plate 11 at one end, and a bent stop plate 12 at the other end. The bent stop plate 12 is a stopper and is bent toward the battery 5. The first slider 7 is in contact with the two bent inclined plates 10, and a nut 13 is fixed to the bent end plate 11. The second slider 9 being a bent member makes its structure simpler and reduces cost.
[0054] Preferably, the box body 4 is opened on one side of the head of the adjusting bolt 14 and is provided with a cover plate 17. The adjusting bolt 14 can be screwed with a tool only by removing the cover plate 17, which is more convenient for the operator to operate.
[0055] Referring to Figure 8 , in the second embodiment, the limiting assembly is a pressure plate 18 , which presses the battery 5 against the inner wall of the housing 4 via screws. This configuration simplifies the structure of the limiting assembly 6 . Specifically, a second stud is provided on either side of the battery 5 within the housing 4 , and both ends of the pressure plate 18 are secured to the second studs via screws. In this embodiment, two pressure plates 18 are provided.
[0056] Example 2
[0057] Referring to Figures 1 to 8, based on Example 1, the present application also provides a street lamp, including the power supply device 2 of Example 1, and also including a lighting device 3, the power supply device 2 and the lighting device 3 are electrically connected through a cable, the power supply device 2 is used to supply power to the lighting device 3, and the power supply device 2 and the lighting device 3 are both arranged on the lamp pole 1.
[0058] The working process of the limiting component 6 of the first solution of this application is further described below:
[0059] When installing the limiting assembly 6, first place the second slider 9 on the upper end surface of the battery 5, and the bent limiting plate 12 on the second slider 9 abuts against a side wall of the battery 5, and rotate the adjusting bolt 14. Since the head of the adjusting bolt 14 abuts against the side wall of the first slider 7 away from the second slider 9, when the adjusting bolt 14 is rotated, the first slider 7 will be driven to move obliquely upward relative to the second slider 9 to adjust its height. The horizontal feed force of the adjusting bolt 14 is converted into a vertical force until the first slider 7 abuts against the first inner wall of the top of the box body 4. At this time, the adjusting bolt 14 cooperates with the nut 13 to always give the first slider 7 a lateral feed force, and the first slider 7 always has a tendency to move along the inclined surface. Similarly, there will always be an interactive squeezing force between the first slider 7 and the first inner wall of the box body 4, and the box body 4 will give the limiting component 6 a downward force and continuously act on the battery 5, so that the battery 5 is pressed and limited by the second slider 9 on the second inner wall at the bottom of the box body 4, so that the battery 5 can be close to the inner wall of the box body 4 to enhance the heat dissipation effect of the battery 5, and the heat of the battery 5 can be directly conducted to the box body 4.

Even if various changes are made to the present application, if these changes fall within the scope of the claims of the present application and their equivalents, they will still fall within the scope of protection of the present application.
