Description

Technical Field

[0001] This utility model relates to the technical field of charging pile equipment, specifically to an outdoor charging pile housing with a gravity self-locking threshold. Background Technology

[0002] Outdoor charging piles are devices installed in outdoor environments to provide power to electric vehicles such as electric cars and electric bicycles. They are an important part of new energy vehicle infrastructure and are commonly divided into DC charging piles, AC charging piles, and DC / AC integrated charging piles. They are often used in public charging stations, highway stations, residential areas, and some commercial locations. Outdoor charging piles are mainly installed in open or semi-open-air locations, so they need to be protected by housings with high protective effects. After the charging pile is installed, it needs to be maintained and inspected regularly. This requires opening the housing door, but existing housing doors do not have effective locking mechanisms, which makes the doors easy to shake during maintenance, causing interference to maintenance personnel. Utility Model Content

[0003] To address the shortcomings of existing technologies, this utility model provides an outdoor charging pile housing with a gravity self-locking threshold. This gravity self-locking threshold automatically locks the door panel after it is opened, preventing the door panel from easily shaking during maintenance and causing interference to maintenance personnel.

[0004] To achieve the above objectives, this utility model provides the following technical solution:

[0005] An outdoor charging pile housing with gravity self-locking threshold includes a cabinet, a door opening on the front of the cabinet, a door panel covering the door opening on the cabinet, and a self-locking limiting support component between the cabinet and the door panel.

[0006] The self-locking limiting support component includes a support assembly, a support rod, a limiting plate, and a self-locking pin.

[0007] The support assembly is fixedly installed on the inner wall of the cabinet, and the top of the support assembly is rotatably connected to the support rod. The self-locking pin is located at the end of the support rod away from the support assembly, and is provided with a middle diameter section, a small diameter section and a large diameter section in sequence from top to bottom along the axial direction.

[0008] The limiting plate is located on the back of the door panel, and a guide groove with a width between the middle diameter section and the small diameter section is opened through its interior. A self-locking hole with the same diameter as the middle diameter section is opened at one end of the guide groove near the support assembly.

[0009] In the above technical solution, the outdoor charging pile housing with gravity self-locking threshold provided by this utility model has the following beneficial effects:

[0010] This utility model, by setting a self-locking pin and a limiting plate, allows the small diameter section of the self-locking pin to slide along the guide groove when the door panel is opened. When the door panel is fully opened, the self-locking pin will be in the self-locking hole position. At this time, under the action of gravity, the self-locking pin will slide down, allowing the middle diameter section of the self-locking pin to insert into the self-locking hole. Since the size of the middle diameter section is larger than the guide groove, the self-locking pin cannot slide in the guide groove at this time, thus achieving the purpose of automatically locking the door panel by gravity and effectively ensuring that the door panel is in a specific position after opening and closing.

[0021] Furthermore, the described features, structures, or characteristics may be combined in any suitable manner in one or more embodiments. Numerous specific details are provided in the following description to give a full understanding of embodiments of the present invention.

[0022] like Figures 1 to 4 As shown, an outdoor charging pile housing with gravity self-locking threshold includes a cabinet 1, a door opening 3 on the front of the cabinet 1, a door panel 2 covering the door opening 3 on the cabinet 1, and a self-locking limiting support component 4 between the cabinet 1 and the door panel 2. The self-locking limiting support component 4 includes a support assembly 41, a support rod 42, a limiting plate 43 and a self-locking pin 44.

[0023] The support assembly 41 is fixedly installed on the inner wall of the cabinet 1, and the top of the support assembly 41 is rotatably connected to the support rod 42. The self-locking pin 44 is located at the end of the support rod 42 away from the support assembly 41, and is provided with a middle diameter section 441, a small diameter section 442 and a large diameter section 443 in sequence from top to bottom along the axial direction. The limiting plate 43 is located on the back of the door panel 2, and a guide groove 431 with a width between the middle diameter section 441 and the small diameter section 442 is provided through it from top to bottom. A self-locking hole 432 with the same diameter as the middle diameter section 441 is provided at the end of the guide groove 431 near the support assembly 41.

[0024] By setting a self-locking pin 44 and a limiting plate 43, the self-locking pin 44 is located at the front end of the support rod 42, and the limiting plate 43 is located on the back of the door panel 2. Under normal conditions, the self-locking pin 44 is slidably located in the guide groove 431 by means of the small diameter section 442. When the door panel 2 is opened, the small diameter section 442 in the self-locking pin 44 will slide along the guide groove 431. When the door panel 2 is fully opened, the self-locking pin 44 will be in the position of the self-locking hole 432. At this time, under the action of gravity, the self-locking pin 44 will slide down, so that the middle diameter section 441 in the self-locking pin 44 is inserted into the self-locking hole 432. Since the size of the middle diameter section 441 is larger than the guide groove 431, the self-locking pin 44 cannot slide in the guide groove 431 at this time, so as to achieve the purpose of automatically locking the door panel 2 by means of gravity and ensuring that the door panel 2 is in a specific position after opening and closing.

[0025] In some improved embodiments, the end of the guide groove 431 away from the self-locking hole 432 is provided with a mounting hole 433 with a diameter larger than that of the large diameter section 443. The length L of the guide groove 431 satisfies the following: when the door panel 2 is fully closed, the distance S between the large diameter section 443 of the self-locking pin 44 and the mounting hole 433 is greater than 0 and S is less than L.

[0026] By setting a mounting hole 433, the diameter of which is larger than the large diameter section 443 of the self-locking pin 44, the self-locking pin 44 can be directly connected to the limiting plate 43 through the mounting hole 433 during assembly. The mounting hole 433 only contacts the self-locking pin 44 during assembly. When the door panel 2 is fully closed, the self-locking pin 44 will slide into the mounting hole 433 in the guide groove 431, but will not come into contact with the mounting hole 433. This method facilitates installation and prevents the self-locking pin 44 from accidentally falling off during use.

[0027] In some improved embodiments, the support assembly 41 includes a support frame 411 connected to the inner wall of the cabinet 1. The support frame 411 is provided with a support nut 412. The support nut 412 is internally threaded with a pivot screw 413 that passes through the support rod 42. The support frame 411 is provided with a pivot boss 414 sleeved on the pivot screw 413. The support rod 42 is provided with a pivot hole 421 corresponding to the position of the pivot boss 414. The support rod 42 is fitted with the pivot boss 414 through the pivot hole 421 with a clearance, forming a mating structure that can rotate around the pivot boss 414 and slide vertically.

[0028] By setting a pivot boss 414, which is located between the pivot screw 413 and the support rod 42, the support rod 42 can rotate around the pivot boss 414 through the pivot hole 421, so that the support rod 42 can freely follow the opening and closing movement of the door panel 2. At the same time, the pivot boss 414 allows the support rod 42 to slide vertically through the pivot hole 421. When the self-locking pin 44 is aligned with the self-locking hole 432 and needs to rely on gravity for self-locking, the support rod 42 can slide down on the outside of the pivot boss 414, making the locking of the support rod 42 and the self-locking pin 44 smoother.

[0029] In some improved embodiments, the support rod 42 is an upward-opening U-shaped structure. The U-shaped structure forms a stable groove cross section through the parallel surfaces on both sides and the horizontal surface at the bottom, which can effectively disperse external loads, such as gravity, wind force, impact force, etc., reduce the risk of bending or breakage caused by single-point force, and has a larger bending section modulus under the same cross-sectional area, which can achieve higher strength with less material and meet the requirements of lightweight design.

[0030] In some improved embodiments, a transition bevel 445 is provided between the intermediate diameter section 441 and the minor diameter section 442. The transition bevel 445 can generate a cone angle between the intermediate diameter section 441 and the minor diameter section 442. The cone angle and gravity can make the self-locking pin 44 located at the center of the self-locking hole 432, so that the intermediate diameter section 441 can fall smoothly into the self-locking hole 432, avoiding the problem of the intermediate diameter section 441 resting on the self-locking hole 432.

[0031] In some improved embodiments, the support frame 411 is connected to the inner wall of the cabinet 1 by bolts, and the top of the support frame 411 is at the same horizontal height as the limiting plate 43. The support frame 411 uses the bolt connection method to allow it to freely determine its own position according to the opening and closing requirements of the door panel 2. That is, before the installation work, the self-locking limiting support component 4 is assembled first, and then the limiting plate 43 is fixed to the back of the door panel 2. Then, the self-locking pin 44 is placed in the self-locking hole 432. Then, the door panel 2 is unfolded to a suitable angle according to the requirements. Finally, the support frame 411 is attached to the inner wall of the cabinet 1, and then the door panel 2 is connected to the cabinet 1 using self-tapping bolts. This method allows the position of the support frame 411 to be determined after the door panel 2 is unfolded, making the installation position of the support frame 411 more accurate and eliminating the need for tedious measurement and positioning work. In addition, it should be further noted that the self-tapping bolt is only one embodiment of this application, and other methods include but are not limited to welding and anchoring.

[0032] It should be further explained that the limiting plate 43 and the support frame 411 adopt the same connection method, which allows the support frame 411 to be installed first, and then the position of the limiting plate 43 to be determined. Both of these methods can achieve the effect of installation without positioning.

[0033] It should be further explained that the above structural dimensions are required to be: mounting hole 433 > large diameter section 443 > self-locking hole 432 ≥ medium diameter section 441 > guide groove 431 > small diameter section 442.

[0034] The working principle of this utility model is as follows: When the door panel 2 is unfolded, the limiting plate 43 moves outward relative to the support rod 42, causing the self-locking pin 44 at the front end of the support rod 42 to slide in the guide groove 431 using the small diameter section 442. At the same time, the support rod 42 rotates adaptively on the support frame 411. When the door panel 2 is fully unfolded, the self-locking pin 44 is aligned with the self-locking hole 432. At this time, under the action of gravity, the middle diameter section 441 of the self-locking pin 44 falls into the self-locking hole 432. Since the size of the middle diameter section 441 is the same as that of the self-locking hole 432 and is larger than the width of the guide groove 431, the self-locking pin 44 in this state cannot continue to move, thereby locking the door panel 2 using the support rod 42.

[0035] When the door panel 2 needs to be closed, the support rod 42 is lifted upwards so that the small diameter inside the self-locking pin 44 is aligned with the guide groove 431. After the door panel 2 is completely closed, it is fixed to the cabinet 1 by its own lock. At this time, the self-limiting support component does not work.

[0036] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
