Description

Technical Field

[0001] This utility model relates to the field of electric vehicle charging technology, specifically a charging gun holder with built-in limiting function. Background Technology

[0002] A charging gun typically refers to a part of the charging equipment used when charging an electric vehicle. It is the cable terminal connecting the electric vehicle's charging port to the power charging station, serving the function of power transmission. A charging gun holder is a device specifically designed to store and support the electric vehicle charging gun. It is usually installed near charging stations, charging piles, or private charging facilities to facilitate the convenient and safe placement of the charging gun after charging is completed, and to prevent the charging gun from getting dirty, damaged, or tripping over. In the process of developing this utility model, the inventors discovered the following problems with the existing technology:

[0003] 1. The existing charging gun holder has a simple structure. When placing the charging gun, it is simply inserted into the holder's limiting slot without a limiting device. It cannot be firmly fixed to the charging gun and is easily detached due to vibration, wind or human factors, resulting in damage or loss of the charging gun.

[0004] 2. To prevent the charging gun from being too loose when fixed, a limiting device needs to be configured. The existing limiting device fits the charging gun too tightly when it is connected to the charging gun, so the charging gun cannot be directly detached from the limiting device during use and cannot be quickly pulled out for use. Utility Model Content

[0005] The purpose of this utility model is to provide a charging gun holder with a built-in limiting function to solve the problem mentioned in the background art that ordinary charging gun holders cannot limit the charging gun when connected, and cannot be quickly unplugged after installation. To achieve the above objective, this utility model provides the following technical solution: a charging gun holder with a built-in limiting function, including a back plate, a fixing rod installed on the top front of the back plate, a connecting block connected to the bottom front of the back plate by bolts, and a limiting component installed at the bottom of the connecting block.

[0006] The limiting component includes a limiting sleeve, a locking block welded to the outside of the limiting sleeve, a ring spring passing through the inside of the locking block, a rotating shaft rotatably connected to the inner wall of the limiting sleeve, a limiting rod and a first gear welded to the surface of the rotating shaft respectively, a second gear meshing on one side of the first gear, a rack meshing on one side of the second gear, and a pressure block adhered to the top of the rack.

[0007] More preferably, the annular spring and the top of the limiting sleeve are connected by a sleeve, and the top of the limiting rod is provided with a hole, through which the annular spring is connected to the limiting rod.

[0008] More preferably, the first gear forms a rotating structure through a rotating shaft and a limiting rod.

[0009] More preferably, the second gear is rotatably connected to the inner wall of the limiting sleeve.

[0010] In a further preferred embodiment, the outer wall of the limiting sleeve is welded with a track, and the rack and the limiting sleeve form a sliding structure through the track.

[0011] More preferably, the rotating shaft, the limiting rod, the first gear, the second gear, the rack, and the pressure block are arranged as one group, and a total of two groups are provided.

[0012] More preferably, the upper surface of the limiting rod is provided with a silicone pad.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] In this invention, a ring spring is sleeved on the outside of the limiting sleeve and passes through the top hole of the limiting rod. When the limiting rod rotates, the horizontal position of the ring spring is controlled by the locking block, and the charging gun is fully inserted into the limiting sleeve. The other end of the limiting rod is tightly fitted to the charging gun shell. At this time, the outer ring spring is deformed under the pull of the two limiting rods. Under the elastic force of the ring spring, the two limiting rods abut against the charging gun shell, realizing two-point fixation and preventing the charging gun from loosening.

[0015] In this invention, the rack is limited by the track to prevent it from disengaging from the second gear when it slides. When the charging gun needs to be disassembled, the pressing block is pressed down, and the rack slides down to rotate the second gear and the first gear until the limiting rod and the limiting sleeve are parallel. At this time, the limiting rod is retracted into the groove of the limiting sleeve, and the charging gun can be quickly pulled out. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figures 1 to 4 This utility model provides a technical solution: a charging gun holder with a built-in limiting function, including a back plate 1, a fixing rod 2 installed on the top front of the back plate 1, a connecting block 3 connected to the bottom front of the back plate 1 by bolts, and a limiting component 4 installed at the bottom of the connecting block 3.

[0023] The limiting component 4 includes a limiting sleeve 401, a locking block 402 welded to the outside of the limiting sleeve 401, a ring spring 403 passing through the inside of the locking block 402, a rotating shaft 404 rotatably connected to the inner wall of the limiting sleeve 401, a limiting rod 405 and a first gear 406 welded to the surface of the rotating shaft 404 respectively, a second gear 407 meshing on one side of the first gear 406, a rack 408 meshing on one side of the second gear 407, and a pressure block 409 bonded to the top of the rack 408.

[0024] In this embodiment, as Figure 1 and Figure 3 As shown, the top of the annular spring 403 and the limiting sleeve 401 are connected by a sleeve. The top of the limiting rod 405 is provided with a hole, and the annular spring 403 is connected to the limiting rod 405 through the hole. It should be noted that the annular spring 403 is sleeved on the outside of the limiting sleeve 401 and passes through the top hole of the limiting rod 405. When the limiting rod 405 rotates, the horizontal position of the annular spring 403 is controlled by the locking block 402.

[0025] In this embodiment, as Figure 3 and Figure 4 As shown, the first gear 406 forms a rotating structure through the rotating shaft 404 and the limiting rod 405. It should be noted that when the limiting rod 405 rotates, the first rotating shaft 404 and the limiting rod 405 rotate synchronously, which further drives the first gear 406 to rotate. The first gear 406 then drives the second gear 407 to rotate in the opposite direction.

[0026] In this embodiment, as Figure 4 As shown, the second gear 407 is rotatably connected to the inner wall of the limiting sleeve 401. It should be noted that the second gear 407 and the limiting sleeve 401 are connected by a shaft. When the second gear 407 rotates in the opposite direction, the limiting sleeve 401 controls the position of the rotation center point of the second gear 407, thereby limiting and supporting the second gear 407.

[0027] In this embodiment, as Figure 4 As shown, a track is welded to the outer wall of the limiting sleeve 401, and the rack 408 forms a sliding structure with the limiting sleeve 401 through the track. It should be noted that the track limits the rack 408, preventing it from disengaging from the second gear 407 when it slides. When the charging gun needs to be disassembled, press down on the pressure block 409, and the rack 408 slides down, causing the second gear 407 and the first gear 406 to rotate until the limiting rod 405 is parallel to the limiting sleeve 401 and is stored in the groove of the limiting sleeve 401, allowing the charging gun to be quickly pulled out.

[0028] In this embodiment, as Figure 1 and Figure 2 As shown, the rotating shaft 404, the limiting rod 405, the first gear 406, the second gear 407, the rack 408, and the pressure block 409 are set as one group, and there are two groups in total; it should be noted that the two groups of components can abut against the two sides of the charging gun to achieve two-point fixation.

[0029] In this embodiment, as Figure 1 and Figure 3 As shown, a silicone pad is provided on the upper surface of the limiting rod 405; it should be noted that the silicone pad on the surface of the limiting rod 405 has a large friction with the charging gun housing, and the limiting effect is better when the limiting rod 405 abuts against the charging gun housing.

[0030] The usage and advantages of this utility model: The charging gun holder with built-in limiting function operates as follows:

[0031] like Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, first, fix the back plate 1 to the wall, then wrap the cable around and hang it on the fixing rod 2. Align the head of the charging gun with the limiting sleeve 401 and insert it. As the charging gun is inserted, it presses against the limiting rods 405. The two limiting rods 405 rotate to the sides via the rotating shaft 404, causing the first gear 406 to rotate counterclockwise. At this time, the other end of the limiting rod 405 pulls the ring spring 403. When the first gear 406 rotates 80 degrees counterclockwise, the charging gun is fully inserted into the limiting sleeve 401, and the other end of the limiting rod 405 is tightly attached to the charging gun housing. When the two limit rods 405 are pulled together, the outer ring spring 403 deforms under the tension of the ring spring 403. Under the elastic force of the ring spring 403, the two limit rods 405 press against the charging gun housing and limit and fix it. When the charging gun needs to be pulled out, simply press the pressure blocks 409 on both sides to drive the rack 408 to slide down, and rotate the second gear 407 clockwise, which in turn drives the first gear 406 to continue to rotate counterclockwise until the limit rod 405 and the limit sleeve 401 are parallel. At this time, the limit rod 405 is stored in the groove of the limit sleeve 401, and the charging gun can be quickly pulled out.

[0032] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
