Description

Technical Field

[0001] This utility model relates to the technical field of charging guns, and in particular to a charging gun for a new energy vehicle charging station. Background Technology

[0002] With the rapid popularization of new energy vehicles, charging piles, as core energy replenishment equipment, directly affect user experience and charging efficiency through their performance and reliability. The charging gun, as a key connection component between the charging pile and the vehicle, must simultaneously meet the requirements of high-current transmission and waterproofing / dustproofing.

[0003] However, in order to meet the requirements of waterproofing and dustproofing, existing charging guns adopt an integrated design. The internal components of the charging gun are usually integrated into a one-piece shell through fixed welding or gluing processes, such as charging terminals and wiring harnesses. The fault tolerance rate during the production and assembly of the charging gun is low, resulting in a high product defect rate. In addition, maintenance requires breaking the shell and replacing the entire functional unit, which makes maintenance costs high. Utility Model Content

[0004] This invention aims to solve at least one of the technical problems existing in the prior art. To this end, this invention proposes a charging gun for a new energy vehicle charging station, which facilitates assembly and maintenance, reduces production defect rates, and lowers maintenance costs.

[0005] A charging gun for a new energy vehicle charging pile according to an embodiment of the present invention includes: a housing with an internal partition plate, one side of the partition plate forming a first inner cavity and the other side of the partition plate forming a second inner cavity, the first inner cavity having a first port and a second port; a terminal assembly including a plug and a protruding ring connected to the plug, the plug being used for plugging into the charging port of a vehicle, the protruding ring being installed in the first port, a first sealing ring being provided between the outer surface of the protruding ring and the inner wall of the first port to seal the gap between the protruding ring and the first port; a wiring harness assembly including a cable and a connecting sleeve sleeved on the radial outer surface of the cable, the cable being used for electrical connection with the plug, the connecting sleeve cooperating with the second port, a second sealing ring being provided between the outer surface of the connecting sleeve and the inner wall of the second port to seal the gap between the connecting sleeve and the second port; and a locking assembly for locking the plug to the charging port of a vehicle, the locking assembly being connected to the plug and disposed in the second inner cavity.

[0006] A charging gun for a new energy vehicle charging station according to an embodiment of the present utility model has at least the following beneficial effects:

[0007] 1. This utility model, by setting up an outer shell, uses a partition plate to divide the inner cavity of the outer shell into a first inner cavity and a second inner cavity. The terminal assembly is installed at the first port of the first inner cavity, and the wire harness assembly is installed at the second port of the first inner cavity, so that the wires of the wire harness assembly are connected to the terminal assembly through the first inner cavity. This facilitates the creation of a sealing structure between the terminal assembly and the first port, as well as between the wire harness assembly and the second port, to prevent water from entering the first inner cavity and causing circuit failure at the connection between the terminal assembly and the wire harness assembly. The second inner cavity can be equipped with a locking assembly. The locking assembly has low waterproof requirements, reducing the waterproof requirements of the second inner cavity. At the same time, it prevents rainwater from flowing from the second inner cavity into the first inner cavity.

[0008] 2. This utility model modularizes the terminal assembly, wire harness assembly, and locking assembly by setting them as separate units. During assembly, the cable can be passed through the first inner cavity to connect the cable to the plug. Then, the second sealing ring is placed on the connecting sleeve to seal the connection between the connecting sleeve and the second port. The first sealing ring is placed on the convex ring to seal the connection between the convex ring and the first port, thereby improving the sealing performance of the first inner cavity and meeting dustproof and waterproof requirements. The detachable sealing structure replaces the traditional welding / gluing process. At the same time, the locking assembly can be inserted into the second inner cavity, improving the product assembly fault tolerance. During maintenance, only the faulty module needs to be replaced without damaging the overall structure, reducing maintenance costs.

[0009] According to an embodiment of the present invention, a charging gun for a new energy vehicle charging pile further includes two clamping blocks. The two clamping blocks clamp the outer surface of the second port and are connected by a first bolt. The clamping blocks are provided with a limiting edge, and the limiting edge abuts against the end of the connecting sleeve.

[0010] According to an embodiment of the present invention, a charging gun for a new energy vehicle charging pile has a connecting ring coaxially arranged at the second port, and the clamping block has an arc surface that matches the radial outer surface of the connecting ring.

[0032] The following description, in conjunction with the accompanying drawings, describes a charging gun for a new energy vehicle charging station according to an embodiment of the present invention.

[0033] Reference Figure 1 The present invention aims to provide an embodiment of a charging gun for a new energy vehicle charging pile.

[0034] This utility model provides a charging gun for a new energy vehicle charging station, referring to... Figure 2 and Figure 3 The device includes a housing 100, and the housing 100 has a partition plate 370 inside. One side of the partition plate 370 forms a first inner cavity 110, and the other side of the partition plate 370 forms a second inner cavity 120. The first inner cavity 110 has a first port 130 and a second port 140.

[0035] It is understood that in this embodiment, by setting up a housing 100, the inner cavity of the housing 100 is divided into a first inner cavity 110 and a second inner cavity 120 by a partition plate 370. The terminal assembly is installed at the first port 130 of the first inner cavity 110, and the wire harness assembly is installed at the second port 140 of the first inner cavity 110, so that the wires of the wire harness assembly are connected to the terminal assembly through the first inner cavity 110. This facilitates the creation of a sealing structure between the terminal assembly and the first port 130, as well as between the wire harness assembly and the second port 140, to prevent water from entering the first inner cavity 110 and causing circuit failure at the connection between the terminal assembly and the wire harness assembly. The second inner cavity 120 can be equipped with a locking assembly. The locking assembly does not have high waterproof requirements, which reduces the waterproof requirements of the second inner cavity 120. At the same time, it prevents rainwater from flowing from the second inner cavity 120 into the first inner cavity 110.

[0036] This utility model provides a charging gun for a new energy vehicle charging station, referring to... Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 It also includes a terminal assembly, a wiring harness assembly, and a locking assembly. The terminal assembly includes a plug 150 and a protruding ring 160 connected to the plug 150. The plug 150 is used for plugging into the charging port of the vehicle. The protruding ring 160 is installed inside the first port 130. A first sealing ring 170 is provided between the outer surface of the protruding ring 160 and the inner wall of the first port 130 to seal the gap between the protruding ring 160 and the first port 130. The wiring harness assembly includes a cable 180 and a connecting sleeve 190 sleeved on the radial outer surface of the cable 180. The cable 180 is used for electrical connection with the plug 150. The connecting sleeve 190 mates with the second port 140. A second sealing ring 200 is provided between the outer surface of the connecting sleeve 190 and the inner wall of the second port 140 to seal the gap between the connecting sleeve 190 and the second port 140. The locking assembly is used to lock the plug 150 into the charging port of the vehicle. The locking assembly is connected to the plug 150 and is disposed in the second inner cavity 120.

[0037] It is understood that this embodiment modularizes the terminal assembly, wire harness assembly, and locking assembly by setting them as separate units. During assembly, the cable 180 can be passed through the first inner cavity 110 to connect the cable 180 to the plug 150. Then, the second sealing ring 200 is fitted onto the connecting sleeve 190 to seal the connection between the connecting sleeve 190 and the second port 140. The first sealing ring 170 is fitted onto the convex ring 160 to seal the connection between the convex ring 160 and the first port 130. This improves the sealing performance of the first inner cavity 110, meeting dustproof and waterproof requirements. A detachable sealing structure replaces the traditional welding / gluing process. At the same time, the locking assembly can be inserted and installed in the second inner cavity 120, improving the product assembly fault tolerance. During maintenance, only the faulty module needs to be replaced without damaging the overall structure, reducing maintenance costs.

[0038] In some embodiments of this utility model, reference is made to Figure 1 and Figure 5 It also includes two clamping blocks 230, which clamp the outer surface of the second port 140. The two clamping blocks 230 are connected by a first bolt 220. The clamping blocks 230 are provided with a limiting edge 210, which abuts against the end of the connecting sleeve 190.

[0039] Understandably, by using two clamping blocks 230 to hold the outer surface of the second port 140, the two clamping blocks 230 are brought close to the wire harness assembly. Furthermore, by using the limiting edge 210 to abut against the end of the connecting sleeve 190, the wire harness assembly is prevented from detaching from the second port 140. Finally, the two clamping blocks 230 are fixed to the housing 100 by the first bolt 220, which enables quick assembly and disassembly of the wire harness assembly, improves the efficiency of cable 180 replacement, and enhances the connection strength between the wire harness assembly and the housing 100, making it less likely for the wire harness assembly to loosen during the user's movement of the charging gun.

[0040] In some embodiments of this utility model, reference is made to Figure 4 and Figure 5 The second port 140 is coaxially provided with a connecting ring 240, and the clamping block 230 is provided with an arc surface that matches the radial outer surface of the connecting ring 240.

[0041] It is understandable that by setting the connecting ring 240, the clamping block 230 matches the radial outer surface of the connecting ring 240 through the arc surface, increasing the contact area between the clamping block 230 and the connecting ring 240, so that the clamping block 230 is firmly installed in the outer shell 100.

[0042] In some embodiments of this utility model, reference is made to Figure 5 and 7 The clamping block 230 is provided with a positioning part 250, and a positioning hole 260 is provided between the connecting ring 240 and the connecting sleeve 190, and the positioning part 250 matches the positioning hole 260.

[0043] It is understandable that by setting the positioning part 250 and the positioning hole 260, the positioning part 250 is inserted into the positioning hole 260, thereby preventing the connecting ring 240 and the connecting sleeve 190 from rotating relative to each other. At the same time, the clamping block 230 is accurately installed in the housing 100, improving the connection strength between the wire harness assembly and the housing 100, and facilitating the installation and positioning of the clamping block 230.

[0044] In some embodiments of this utility model, reference is made to Figure 5 The plug 150 is provided with a flange 270, and the flange 270 is provided with a second bolt 280. The flange is connected to the housing 100 by the second bolt 280.

[0045] Understandably, the cooperation between the flange 270 and the connecting ring 240 enables quick assembly and disassembly of the terminal assembly, improves the efficiency of terminal assembly replacement, and enhances the connection strength between the terminal assembly and the housing 100, making it less likely for the terminal assembly to detach from the housing 100 during the user's plugging and unplugging of the charging gun.

[0046] In some embodiments of this utility model, a grip portion 290 is provided on the outer surface of the housing 100. The grip portion 290 is located near the cable 180 and is a part for the user to hold the charging gun.

[0047] Understandably, the ergonomically designed grip 290 reduces grip pressure, and the grip 290 can be equipped with anti-slip textures to prevent the user from slipping when holding the charging gun.

[0048] In some embodiments of this utility model, the plug 150 is provided with a support base 300, and the locking assembly includes a hook 310 rotatably disposed on the support base 300 and a spring that drives the hook 310 to rotate. The hook 310 is used to engage with the charging port of the car.

[0049] Understandably, when the user inserts the charging gun into the car's charging port, the hook 310 rotates, overcoming the spring force, so that the hook of the hook 310 engages with the car's charging port, preventing the charging gun from detaching from the car's charging port.

[0050] In some embodiments of this utility model, reference is made to Figure 6 The support base 300 has two upright plates 320, and a first shaft 330 is provided between the two upright plates 320. The hook 310 is rotatably mounted on the first shaft 330. It can be understood that by using the two upright plates 320 to support the first shaft 330, the load-bearing capacity of the first shaft 330 can be improved, and the reliability of the locking assembly can be ensured.

[0051] In some embodiments of this utility model, reference is made to Figure 5 and Figure 6 The hook 310 is provided with a pressing member 340, which is located at the end of the first shaft 330 away from the plug 150. The housing 100 has a guide channel 350 extending from the inside of the second inner cavity 120 to the outside, and the pressing member 340 can move along the guide channel 350.

[0052] Understandably, when the pressing member 340 is pressed down, the pressing member 340 can move along the guide channel 350, so that the pressing member 340 can smoothly rotate the hook 310. In addition, the hook 310 can be connected to the pressing member 340 by a snap-fit ​​method to prevent the pressing member 340 from detaching from the hook 310.

[0053] In some embodiments of this utility model, reference is made to Figure 6 The spring is a torsion spring 360, which is mounted on the first shaft 330. The two abutting ends 380 of the torsion spring 360 are located close to the pressing member 340. It can be understood that by mounting the torsion spring 360 on the first shaft 330, the layout can be made more compact, reducing the size of the locking assembly, and ensuring that the spring has sufficient elasticity to drive the hook 310 to fasten the car's charging port.
