Description

Technical Field

[0001] This application relates to the field of charging pile technology, and in particular to a wall-mounted structure for a DC charging pile and a DC charging pile. Background Technology

[0002] Charging piles need to be fixed to walls or columns using a frame. Specifically, the frame is first fixed to the wall or column, and then the charging pile is assembled onto the frame. However, there is a lack of necessary constraints between the charging pile and the frame, which makes it easy for the charging pile to detach from the frame.

[0003] An existing patent (publication number: CN219530271U) discloses a wall-mounted structure for a charging pile and a charging pile, belonging to the field of charging pile technology. The wall-mounted structure includes a charging pile box, a mounting bracket, and a wall-mounting support. The mounting bracket includes a first plate and multiple second plates connected to the first plate; the first plate is connected to the charging pile box. The wall-mounting support has a first mounting structure and multiple notches. The first mounting structure is used to connect to the installation position of the charging pile. The notches include a first segment and a second segment that are connected, with the second segment located in a first direction from the first segment. The multiple second plates of the mounting bracket are used to pass through the multiple notches corresponding to the first segment and move along the first direction to the second segment. The width of the second plate is greater than the width of the second segment. According to the wall-mounted structure of the charging pile provided in this application, the second plates constrain the second segment of the notch. When the wall-mounting support is installed on the wall, even if the first mounting structure becomes loose at the installation position of the charging pile box, the wall-mounting support is not easily detached from the charging pile box.

[0004] The device in the aforementioned comparative document can prevent the wall-mounted bracket from easily detaching from the charging station box, but it still requires a padlock to achieve the anti-theft effect. In order to further optimize the anti-theft effect of this structure, a wall-mounted structure for a DC charging station and a DC charging station are proposed. Utility Model Content

[0005] The purpose of this application is to provide a wall-mounted structure and a DC charging pile that integrates a locking component with a wall-mounting component, achieving a good anti-theft effect without the need for a padlock, thus solving the problems mentioned in the background art.

[0006] The technical solution provided in this application for a wall-mounted structure of a DC charging pile is as follows: A wall-mounted structure of a DC charging pile includes a charging pile box, a hanging bracket assembly and a wall-mounted support assembly. The hanging bracket assembly includes two fixing plates fixedly connected to the back of the charging pile box. Two lugs are fixedly connected to the outer surface of each fixing plate. Each lug has a locking hole inside. A slot is formed between the lug and the fixing plate.

[0007] The wall-mounted bracket assembly includes a bracket body. The bracket body has a first stepped surface and a second stepped surface inside. Two insertion holes are formed at the top of each of the first and second stepped surfaces. A screw positioning bracket is fixedly connected to the inner wall of each of the first and second stepped surfaces. A bidirectional screw is rotatably sleeved on the inner wall of each screw positioning bracket. Two locking blocks are threaded onto the outer surface of each bidirectional screw. One end of each locking block is adapted to a lock hole. A worm gear is fixedly connected to the middle section of each bidirectional screw. A rotating rod is rotatably sleeved on the inner wall of the bracket body. Two worms are mounted on the outer surface of the rotating rod, and the two worms mesh with two worm gears respectively. A knob is fixedly connected to the top of the rotating rod, and a specially designed groove is formed at the top of the knob.

[0008] By adopting the above technical solution, the wall-mounted bracket assembly integrates a worm gear / worm transmission mechanism with a two-way lead screw. Rotating the knob drives the lock block to insert into the lock hole of the lug, achieving mechanical self-locking anti-theft. Compared to traditional padlocks, this structure is more convenient to use, eliminating the need to carry an additional padlock for locking, significantly improving the ease of connection and installation.

[0009] Preferably, the four lugs are respectively inserted into the four sockets, and the slots are engaged with the outside of the first and second step surfaces.

[0010] By adopting the above technical solution, four lugs are inserted into four sockets, so that the bracket assembly and the wall-mounted bracket assembly are precisely aligned. The slots are engaged with the outside of the first and second step surfaces to form a constraint, prevent the charging pile box from detaching, and improve the structural stability.

[0011] Preferably, the top of the bracket body is provided with a plurality of first mounting holes, and the bottom of the bracket body is provided with a plurality of second mounting holes.

[0012] By adopting the above technical solution, the first mounting hole at the top and the second mounting hole at the bottom of the bracket body can be fixed to the wall or column with bolts, providing multi-point installation support, ensuring that the wall-mounted bracket assembly is firmly installed, and adapting to different installation scenarios.

[0013] Preferably, each of the lead screw positioning frames has two guide posts installed inside, and the four locking blocks are slidably sleeved on the outer surfaces of the four guide posts. The outer surface of each bidirectional lead screw is fixedly connected with two limiting rings.

[0014] By adopting the above technical solution, the guide post inside the screw positioning frame is slidably connected to the locking block, so that the locking block moves linearly along the guide post, avoiding rotational deviation of the locking block, ensuring that the locking block is accurately inserted into the lock hole, and improving the locking reliability.

[0015] Preferably, two limiting rings are fixedly connected to the outer surface of each of the bidirectional lead screws.

[0016] By adopting the above technical solution, the limiting ring on the outer surface of the bidirectional lead screw can limit the movement stroke of the locking block and prevent the locking block from moving excessively and causing it to disengage.

[0017] Preferably, the knob is embedded in the top of the first stepped surface and can be rotated. The outside of the special groove is provided with a long handle, and the output end of the long handle is fixedly connected to a special block, which is adapted to the special groove.

[0018] By adopting the above technical solution, the knob is embedded in the top of the first step surface and can be rotated. The long handle is matched with a special block and a special groove, which makes it easy for the operator to rotate the knob. The worm gear transmission mechanism drives the lock block to move, realizing convenient locking and unlocking operations.

[0019] Preferably, a fixing block is fixedly connected to the inner wall of the second step surface, and the bottom end of the rotating rod is rotatably sleeved on the inner wall of the fixing block.

[0020] By adopting the above technical solution, the fixed block on the inner wall of the second step supports the bottom end of the rotating rod, ensuring the stability of the rotating rod when it rotates, avoiding the shaking of the transmission mechanism, and ensuring the reliability of the synchronous movement of the locking block.

[0021] This utility model also provides a DC charging pile, including a DC charging pile body and a wall-mounted structure as described above, wherein the DC charging pile body is installed inside the charging pile box.

[0022] By adopting the above technical solution, installing the DC charging pile body inside the charging pile box can effectively protect it, reduce the probability of damage to the DC charging pile body, and extend the service life of the DC charging pile body.

[0023] In summary, this application includes at least one of the following beneficial technical effects:

[0024] This invention relates to a wall-mounted structure for a DC charging pile. The DC charging pile is fixed to the back of the charging pile box via a mounting plate of a bracket assembly. Lugs are inserted into the sockets of the wall-mounted bracket assembly, and slots engage with the outer surfaces of the first and second steps to form initial positioning and constraint. Rotating a knob drives a worm gear on a rotating rod to mesh with a worm wheel, which in turn drives two bidirectional lead screws to rotate, causing the locking block to slide along a guide post into the lock hole. A limit ring restricts the travel of the locking block, integrating the locking assembly with the wall-mounted bracket assembly. Automatic locking can be achieved through mechanical transmission without the need for an external padlock. Furthermore, the specially designed groove and the specially designed block at the end of the long handle are non-standard matching, requiring only a special tool for operation. This enhances the anti-theft effect and simplifies anti-theft work. At the same time, the lead screw positioning bracket and the fixing block ensure transmission stability, simplify the installation process, and enhance structural reliability.

Detailed Implementation

[0033] The following is in conjunction with the appendix Figure 1 -Appendix Figure 6 This application will be described in further detail below.

[0034] Example 1: A wall-mounted structure for a DC charging pile includes a charging pile box 1, a hanging bracket assembly 2, and a wall-mounted support assembly 3. The hanging bracket assembly 2 includes two fixing plates 201 fixedly connected to the back of the charging pile box 1. Each fixing plate 201 has two lugs 202 fixedly connected to its outer surface. Each lug 202 has a locking hole 203 inside. A slot 204 is formed between the lug 202 and the fixing plate 201. The wall-mounted support assembly 3 includes a support body 301. The top of the support body 301 has multiple first mounting holes 302, and the bottom of the support body 301 has multiple second mounting holes 303. The first mounting holes 302 at the top and the second mounting holes 303 at the bottom of the support body 301 can be fixed to a wall or column with bolts, providing multi-point installation support to ensure that the wall-mounted support assembly 3 is firmly installed and adaptable to different installation scenarios.

[0035] The bracket body 301 has a first stepped surface 304 and a second stepped surface 305 inside. The top of the first stepped surface 304 and the second stepped surface 305 each have two sockets 316. Four lugs 202 are inserted into the four sockets 316 respectively. The slots 204 are engaged with the outside of the first stepped surface 304 and the second stepped surface 305. The four lugs 202 are inserted into the four sockets 316, so that the hanging bracket assembly 2 and the wall-mounted bracket assembly 3 are precisely aligned. The slots 204 are engaged with the outside of the first stepped surface 304 and the second stepped surface 305 to form a constraint, prevent the charging pile box 1 from falling off, and improve the structural stability. The inner walls of the first stepped surface 304 and the second stepped surface 305 are fixedly connected with screw positioning brackets 306. The inner wall of each screw positioning bracket 306 is rotatably fitted with a bidirectional screw 307. The outer surface of each bidirectional screw 307 is threaded with two locking blocks 308. One end of the locking block 308 is adapted to the lock hole 203.

[0036] Each lead screw positioning bracket 306 has two guide posts 309 installed inside. Four locking blocks 308 are slidably sleeved on the outer surfaces of the four guide posts 309. Two limit rings 310 are fixedly connected to the outer surface of each bidirectional lead screw 307. The guide posts 309 inside the lead screw positioning bracket 306 are slidably connected to the locking blocks 308, allowing the locking blocks 308 to move linearly along the guide posts 309, preventing the locking blocks 308 from rotating or shifting, ensuring that the locking blocks 308 are accurately inserted into the lock hole 203, and improving locking reliability. Two limiting rings 310 are fixedly connected to the outer surface of each bidirectional lead screw 307. The limiting rings 310 on the outer surface of the bidirectional lead screw 307 can limit the movement stroke of the locking block 308 and prevent the locking block 308 from moving excessively and causing it to disengage. A worm gear 311 is fixedly connected to the middle section of each bidirectional lead screw 307. A rotating rod 312 is rotatably sleeved on the inner wall of the bracket body 301. Two worms 313 are installed on the outer surface of the rotating rod 312. The two worms 313 are respectively meshed with the two worm gears 311.

[0037] A knob 314 is fixedly connected to the top of the rotating rod 312. A special groove 315 is formed at the top of the knob 314. The knob 314 is embedded in the top of the first stepped surface 304 and can rotate. A long handle 317 is provided outside the special groove 315. A special block 318 is fixedly connected to the output end of the long handle 317. The special block 318 is adapted to the special groove 315. The knob 314 is embedded in the top of the first stepped surface 304 and can rotate. The long handle 317 is connected to the special groove via the special block 318. The knob 314 is rotated by the operator to drive the locking block 308 to move through the worm gear transmission mechanism, thus realizing convenient locking and unlocking operations. The inner wall of the second step surface 305 is fixedly connected to the fixing block 319. The bottom end of the rotating rod 312 is rotatably sleeved on the inner wall of the fixing block 319. The fixing block 319 on the inner wall of the second step surface 305 supports the bottom end of the rotating rod 312, ensuring the stability of the rotating rod 312 when rotating, avoiding the transmission mechanism from shaking, and ensuring the reliability of the synchronous movement of the locking block 308.

[0038] Example 2: A DC charging pile. Based on the same concept as Example 1 above, this example proposes a DC charging pile body and a wall-mounted structure as described above. The DC charging pile body is installed inside the charging pile box 1. By adopting the above technical solution, installing the DC charging pile body inside the charging pile box 1 can effectively protect it, reduce the probability of damage to the DC charging pile body, and extend the service life of the DC charging pile body.

[0039] The implementation principle of this application embodiment is as follows: First, the wall-mounted bracket assembly 3 is fixed to the wall or column through the first mounting hole 302 at the top and the second mounting hole 303 at the bottom of the bracket body 301. Then, the hanging bracket assembly 2 on the back of the charging pile box 1 is aligned with the wall-mounted bracket assembly 3, so that the four lugs 202 are inserted into the four sockets 316 respectively, and the slots 204 are engaged with the outside of the first step surface 304 and the second step surface 305, thus completing the initial positioning and support. When locking is required, the operator uses the long handle 317 to drive the special block 318 into the special groove 315 at the top of the knob 314. Rotating the knob 314 drives the rotating rod 312 to rotate, and the worm gear 313 on the outer surface of the rotating rod 312 engages with the worm wheel 311, driving the bidirectional lead screw 307 to rotate within the lead screw positioning frame 306. Since the locking block 308 is threadedly connected to the outer surface of the bidirectional lead screw 307, and the locking block 308 is slidably sleeved on the guide post 309, when the bidirectional lead screw 307 rotates, it pushes the locking block 308 to move linearly along the guide post 309, so that one end of the locking block 308 is inserted into the lock hole 203 of the lug 202. At the same time, the limiting ring 310 restricts the movement of the locking block 308 to prevent excessive displacement. At this time, the hanging bracket assembly 2 and the wall-mounted bracket assembly 3 are mechanically locked together to achieve the anti-theft effect without the need for an additional padlock, ultimately ensuring that the charging pile box 1 is firmly installed and not easily detached.

[0040] The embodiments described in this specific implementation are preferred embodiments of this application and are not intended to limit the scope of protection of this application. Identical components are represented by the same reference numerals. Therefore, all equivalent changes made to the structure, shape, and principle of this application should be covered within the scope of protection of this application.
