Description
Technical Field

[0002] In the context of new energy vehicles, with the increase in battery energy density and charging rate, electric vehicle charging stations are required to input higher voltage and greater current per unit time to achieve high-power charging. To address this, vehicle charging stations typically increase the current and cable diameter to achieve high-power charging. However, thickening the cable leads to stress concentration at the ends of the charging cable, especially high-voltage charging cables. Prolonged stress on the charging cable reduces the structural strength of the contacts and the connection points, affecting the lifespan of the vehicle charging station. Summary of the Invention

[0048] In the description of this invention, "a plurality of" means two or more, and "several" means one or more.
[0049] The vehicle charging dock 1 according to an embodiment of the present invention is described below with reference to the accompanying drawings.
[0050] like Figures 1-6 As shown, the vehicle charging socket 1 according to an embodiment of the present invention includes a housing 100, a high-voltage contact 200, a high-voltage charging cable 300, and a pressure plate 400.
[0051] The housing 100 has a charging channel 110 inside, which has a charging inlet 111 and a charging outlet 112.
[0052] A high-voltage contact 200 is installed within the charging channel 110 and protrudes from the charging inlet 111. A high-voltage contact weld 210 is provided at the end of the high-voltage contact 200 furthest from the charging inlet 111. A high-voltage charging cable 300 extends into the charging channel 110 from the charging outlet 112. A high-voltage wire weld 310 is provided at the end of the high-voltage charging cable 300 facing the high-voltage contact 200. The high-voltage wire weld 310 and the high-voltage contact weld 210 are welded together. A pressure plate 400 is installed within the charging channel 110. The pressure plate 400 has a limiting structure 410, which engages with the weld joint between the high-voltage wire weld 310 and the high-voltage contact weld 210 to limit the weld joint.
[0053] For example, the charging gun is inserted into the charging inlet 111 and contacts the high-voltage contact 200 to achieve charging. The high-voltage contact 200 is fitted into the shape of the housing 100 and installed inside the housing 100. The pressure plate 400 is fixed to the housing 100 by fasteners and provides support and positioning for the high-voltage contact 200.
[0054] The charging channel 110 extends in a straight line along the front-to-back direction (this front-to-back direction is only for describing the relative positions of the components and is not limited to the front-to-back direction of the vehicle), and the charging inlet 111 and the charging outlet 112 face the two ends of the charging channel 110 respectively, achieving the purpose of linear power supply. The vehicle charging socket 1 can be a DC charging socket, the high-voltage contact 200 is a DC high-voltage contact 200, and the high-voltage charging cable 300 is a DC charging cable. The high-voltage contact 200 protrudes from the charging inlet 111. It can be understood that the above-mentioned "protrusion" is not limited to extending out, but refers to being able to connect with the high-voltage contact 200 by extending into the charging inlet 111 outside the housing 100. The high-voltage charging cable 300 extends into the charging channel 110 from the charging outlet 112, and is connected to the high-voltage contact 200. The high-voltage charging cable 300 receives electrical energy from the charging gun to power the entire vehicle.
[0055] According to an embodiment of the present invention, the vehicle charging socket 1 has a high-voltage contact 200 provided with a high-voltage wire welding member 310, and a high-voltage charging cable 300 provided with a high-voltage wire welding member 310. The high-voltage contact 200 and the high-voltage charging cable 300 are welded together by the high-voltage wire welding member 310, so that the high-voltage charging cable 300 and the high-voltage contact 200 have a high connection strength. The high-voltage contact 200 extends from one end of the pressure plate 400 toward the charging inlet 111 (i.e., the front side), and the high-voltage charging cable 300 extends from one end of the pressure plate 400 toward the charging outlet 112 (i.e., the rear side).
[0056] The high-voltage wire welding component 310 and the high-voltage wire welding component 310 are welded into a whole and are jointly limited by the limiting structure 410, thereby fixing the connection between the high-voltage charging cable 300 and the high-voltage contact 200 to the pressure plate 400. The pressure plate 400 can restrict the relative movement of the high-voltage contact welding component 210 and the high-voltage wire welding component 310, such as rotation and misalignment, and form a reinforcement at the connection between the high-voltage contact 200 and the high-voltage charging cable 300. This prevents the connection from being twisted or bent at the connection between the high-voltage contact 200 and the high-voltage charging cable 300, which would result in an unstable connection. Furthermore, the high-voltage contact 200 will not be subjected to bending or twisting of the wire harness, which improves the connection strength between the high-voltage charging cable 300 and the high-voltage contact 200, enhances charging stability, and extends the service life of the vehicle charging socket 1.
[0057] Therefore, the vehicle charging socket 1 according to the embodiment of the present invention has the advantages of strong connection and long service life.
[0058] In some specific embodiments of the present invention, such as Figure 5 As shown, both the high-voltage contact welding component 210 and the high-voltage line welding component 310 are constructed as sheets and are attached to each other. The surfaces of the high-voltage contact welding component 210 and the high-voltage line welding component 310 that are attached to each other are welded together.
[0059] The high-voltage contact welding component 210 and the high-voltage line welding component 310 are constructed into sheet-like shapes to achieve good fit. The high-voltage contact welding component 210 and the high-voltage line welding component 310 have a large contact area, and the connection between the high-voltage contact welding component 210 and the high-voltage line welding component 310 can be made more secure through welding.
[0060] Furthermore, such as Figure 5 As shown, both the high-voltage contact 200 and the high-voltage charging cable 300 have circular cross-sections. The width of the high-voltage contact weld 210 is greater than the diameter of the high-voltage contact 200, and the width of the high-voltage cable weld 310 is greater than the diameter of the high-voltage charging cable 300. That is, the high-voltage contact weld 210 extends beyond the radial contour of the high-voltage contact 200, and the high-voltage cable weld 310 extends beyond the radial contour of the high-voltage charging cable 300. The widths of the high-voltage contact weld 210 and the high-voltage cable weld 310 can be equal.
[0061] For example, both the high-voltage contact weldment 210 and the high-voltage wire weldment 310 are constructed in a rectangular shape. The pressure plate 400 can limit the high-voltage contact weldment 210 and the high-voltage wire weldment 310 on both sides of the thickness direction. The pressure plate 400 is clamped on both sides of the high-voltage contact weldment 210 and the high-voltage wire weldment 310 by the limiting structure 410, thereby ensuring that the high-voltage contact weldment 210 and the high-voltage wire weldment 310 do not rotate relative to the pressure plate 400, and ensuring that the angle of the high-voltage connector (not shown in the figure) at the end of the charging cable reaches the desired position. At the same time, the high-voltage contact weldment 210 and the high-voltage wire weldment 310 will not move or rotate relative to the pressure plate 400 along their thickness direction, thereby improving the limiting reliability of the pressure plate 400 on the high-voltage contact 200 and the high-voltage charging cable 300. Furthermore, the pressure plate 400 is installed in the charging channel 110, so that the high-voltage contact 200 and the high-voltage charging cable 300 can be relatively stably held in the charging channel 110.
[0062] In some specific embodiments of the present invention, such as Figure 3 and Figure 5 As shown, the high-voltage contact welding component 210 is located on one side of the central axis of the high-voltage contact component 200, and the high-voltage wire welding component 310 is welded to the side of the high-voltage contact welding component 210 facing the central axis of the high-voltage contact component 200.
[0063] This arrangement ensures that the high-voltage contact 200 and the high-voltage charging cable 300 are coaxially aligned, with the high-voltage wire weldment 310 located at the central axis of the high-voltage contact 200. This maintains high positional accuracy for both the high-voltage contact 200 and the high-voltage charging cable 300, thereby reducing space requirements and charging losses. The appropriate installation positions of the high-voltage contact weldment 210 and the high-voltage wire weldment 310 minimize the space occupied by the high-voltage contact 200 and the high-voltage charging cable 300 within the charging channel 110.
[0064] In some specific embodiments of the present invention, such as Figure 2 As shown, the pressure plate 400 has a positioning hole 420 extending along its axial direction. The limiting structure 410 is a limiting groove communicating with the positioning hole 420. The limiting groove passes through the end face of the pressure plate 400 facing the charging inlet 111. The positioning hole 420 passes through the end face of the pressure plate 400 facing the charging outlet 112. The high-voltage charging cable 300 passes through the positioning hole 420. The high-voltage cable welding part 310 and the high-voltage contact welding part 210 are inserted into the limiting groove.
[0065] The pressure plate 400 abuts against the end face of the high-voltage contact 200 facing the charging outlet 112, thereby pressing the high-voltage contact 200 against the charging inlet 111 of the housing 100. The high-voltage charging cable 300 passes through the positioning hole 420 from the charging outlet 112 side. The high-voltage wire welding piece 310 and the high-voltage contact welding piece 21 are jointly inserted into the limiting groove. The high-voltage contact 200 protrudes from the limiting groove side of the pressure plate 400, while the high-voltage charging cable 300 extends from the side facing the positioning hole 420. Both the high-voltage contact 200 and the high-voltage charging cable 300 are fixed to the pressure plate 400 via the high-voltage contact welding piece 21 and the high-voltage wire welding piece 310.
[0066] In addition, the positioning hole 420 extends along the axial direction of the pressure plate 400, and the positioning hole 420 fits with the outer peripheral surface of the high voltage charging cable 300. The high voltage charging cable 300 and the positioning hole 420 are interference fit, and the positioning hole 420 plays a guiding and positioning role for the high voltage charging cable 300.
[0067] Furthermore, such as Figure 2 and Figure 4 As shown, the limiting groove penetrates the outer peripheral surface of the pressure plate 400. The limiting groove is easy to process as it penetrates the outer peripheral surface of the pressure plate 400. The limiting groove and the inner peripheral wall of the housing 100 form a closed structure, which reduces the weight of the pressure plate 400 and facilitates the assembly of the high-voltage contact welding part 210 and the high-voltage line welding part 310 with the limiting groove.
[0068] In some specific embodiments of the present invention, such as Figure 2 As shown, the housing 100 includes a charging base flange 120, a dust cover 130, and a charging base rear cover 140.
[0069] A charging inlet 111 is formed in the charging base flange 120. A high-voltage contact 200, a high-voltage charging cable 300, and a pressure plate 400 are all located within the charging base flange 120. A dust cover 130 is installed on the charging base flange 120 and is used to open and close the charging inlet 111. A charging base rear shell 140 is installed on the charging base flange 120 and, together with the charging base flange 120, defines the charging channel 110. A charging outlet 112 is formed in the charging base rear shell 140. The high-voltage charging cable 300 extends from the charging base flange 120 to the charging base rear shell 140 and exits from the charging outlet 112.
[0070] The charging socket flange 120 is installed inside the vehicle's sheet metal structure. The high-voltage contact 200, high-voltage charging cable 300, and pressure plate 400 are located within the charging socket flange 120. A dust cover 130 is installed on the charging socket flange 120 and is used to open and close the charging inlet 111. For example, the dust cover 130 is hinged to one side of the charging inlet 111, and can be opened and closed by rotation to cover the charging inlet 111 when charging is not needed, thus providing dust and water protection. The charging socket rear cover 140, assembled integrally with the charging socket flange 120, guides the high-voltage charging cable 300, allowing it to supply power to various vehicle components in a straight line. It also seals the charging channel 110 on the charging outlet 112 side, achieving good charging sealing for the high-voltage charging cable 300 and ensuring safety.
[0071] In some specific embodiments of the present invention, such as Figure 2 As shown, the outer peripheral surface of the charging base flange 120 is provided with a charging base buckle 121, and the inner peripheral surface of the charging base rear shell 140 is provided with a rear shell groove 141 that cooperates with the charging base buckle 121. The charging base buckle 121 is engaged with the rear shell groove 141.
[0072] For example, multiple charging base buckles 121 are spaced apart along the circumference of the charging base flange 120, and multiple rear shell slots 141 corresponding to the multiple charging base buckles 121 are provided on the inner circumferential surface of the charging base rear shell 140. The processing of the charging base buckles 121 and the rear shell slots 141 is relatively convenient, and the engagement of the charging base buckles 121 and the rear shell slots 141 facilitates the assembly and disassembly of the charging base flange 120 and the charging base rear shell 140.
[0073] In some specific embodiments of the present invention, such as Figure 2 As shown, the vehicle charging dock 1 also includes a front sealing gasket 500.
[0074] The front sealing gasket 500 is located in the charging channel 110 and between the pressure plate 400 and the rear shell 140 of the charging base. The front sealing gasket 500 is provided with a first wire harness through hole 510, through which the high-voltage charging cable 300 passes.
[0075] The front sealing gasket 500 forms a seal with the pressure plate 400 and the charging base rear shell 140 on both sides of its thickness direction, and the front sealing gasket 500 forms a seal with the outer peripheral surface of the high voltage charging cable 300 through the first wire harness through hole 510. The outer peripheral surface of the front sealing gasket 500 forms a seal with the inner peripheral surface of the shell 100, so that the front sealing gasket 500 forms a seal in both the axial and radial directions along the charging channel 110.
[0076] In addition, the charging base flange 120 and the charging base rear shell 140 are engaged by the charging base buckle 121 and the rear shell slot 141, which can keep the charging channel 110 with a suitable axial length, thereby ensuring that the front sealing gasket 500 can be assembled in place and ensuring the sealing effect inside the charging channel 110.
[0077] In some specific embodiments of the present invention, such as Figure 2 As shown, the charging dock back cover 140 includes a back cover body 142, a locking cover 143, and a support member 144.
[0078] The rear shell body 142 is mounted on the charging base flange 120. The rear shell body 142 has a rear shell through hole 1421, and a rear shell buckle 1422 is formed on the outer side of the rear shell body 142. The locking cover 143 has a cover slot 1431, and the rear shell buckle 1422 is engaged with the cover slot 1431. The charging outlet 112 is formed in the locking cover 143. The support member 144 is disposed between the rear shell body 142 and the locking cover 143. The high-voltage charging cable 300 is led out of the charging channel 110 through the rear shell through hole 1421 and the charging outlet 112 and is held by the support member 144.
[0079] The rear shell body 142 and the locking cover 143 are installed as one unit by engaging the rear shell buckle 1422 with the cover slot 1431. The support member 144 is respectively fitted to the rear shell body 142 and the locking cover 143 on both sides along the axial direction of the charging channel 110. The support member 144 is clamped and fixed by the rear shell body 142 and the locking cover 143, and the high-voltage charging cable 300 is clamped by the support member 144. Thus, the support member 144 plays a guiding and supporting role for the high-voltage charging cable 300. The support member 144 supports the outer circumference of the high-voltage charging cable 300, reducing the torsional and lateral forces on the high-voltage charging cable 300 during vehicle assembly, thereby improving the service life of the high-voltage charging cable 300.
[0080] Furthermore, such as Figure 6 As shown, the support member 144 is constructed with multiple grippers 1441, which surround the high-voltage charging cable 300 and jointly clamp the high-voltage charging cable 300.
[0081] The gripper 1441 has a certain elasticity. By surrounding the high-voltage charging cable 300 and pressing the gripper 1441 on the outside of the gripper 1441 towards the high-voltage charging cable 300 with the locking cover 143, the gripper 1441 deforms and clamps the high-voltage charging cable 300. This allows the support member 144 to provide support for the high-voltage charging cable 300 along the axial direction of the high-voltage charging cable 300, thereby further reducing the torsional and lateral forces on the high-voltage charging cable 300.
[0082] Furthermore, such as Figure 6 As shown, the inner circumferential surface of the locking cover 143 is provided with multiple support grooves 1432, and multiple claws 1441 respectively cooperate with multiple support grooves 1432. The outer surface of each claw 1441 is constructed as an inclined surface 1442 that gradually slopes from the charging inlet 111 to the charging outlet 112 towards the center of the support member 144.
[0083] Multiple grippers 1441 engage with multiple support grooves 1432 respectively, preventing relative rotation between the support member 144 and the locking cover 143. When the grippers 1441 are inserted into the support grooves 1432, the inclined surfaces 1442 of the grippers 1441 engage with the support grooves 1432. The locking cover 143 applies pressure towards the high-voltage charging cable 300 through the inner wall of the support grooves 1432, enabling the grippers 1441 to more firmly hold the high-voltage charging cable 300. Even if the side of the high-voltage charging cable 300 facing the charging outlet 112 is subjected to tension, the tension will not be transmitted to the high-voltage contact member 200, thereby ensuring the structural strength of the connection between the high-voltage charging cable 300 and the high-voltage contact member 200.
[0084] In some specific embodiments of the present invention, such as Figure 2 and Figure 4 As shown, the vehicle charging station 1 also includes a rear sealing gasket 600.
[0085] The rear sealing gasket 600 is located inside the rear housing through hole 1421. The inner wall of the rear housing through hole 1421 is constructed with a limiting step 1423. The rear sealing gasket 600 is located between the limiting step 1423 and the support member 144. The rear sealing gasket 600 is provided with a second wire harness through hole 610, through which the high-voltage charging cable 300 passes.
[0086] The rear housing through hole 1421 is constructed with a limiting step 1423 to support one side of the rear sealing gasket 600 in the thickness direction, while the end face of the support member 144 is supported on the other side of the rear sealing gasket 600 in the thickness direction.
[0087] The rear sealing gasket 600 is pressed together by the limiting step 1423 and the support member 144, thus forming a seal along the axial direction of the high-voltage charging cable 300. Furthermore, the rear sealing gasket 600 forms a radial seal by engaging with the inner wall of the rear housing through-hole 1421 and remains fixed to the rear housing body 142. The rear sealing gasket 600 also forms a seal with the outer circumferential surface of the high-voltage charging cable 300 through the second wiring harness through-hole 610. Therefore, the rear sealing gasket 600 forms seals both axially and radially along the charging channel 110, ensuring good sealing of the high-voltage charging cable 300 at the charging outlet 112. In addition, the front sealing gasket 500 and the rear sealing gasket 600 together seal the vehicle charging socket 1, achieving good waterproof safety.
[0088] In some specific embodiments of the present invention, such as Figure 5 As shown, the high-voltage contact 200 includes a contact housing 211, a conductive spring 212, and a sealing ring 213.
[0089] A conductive spring 212 is disposed on the contact housing 211 and extends out of the contact housing 211 toward the charging inlet 111. A high-voltage contact weld 210 is disposed on one end of the contact housing 211 toward the charging outlet 112 and is connected to the conductive spring 212. A sealing ring 213 surrounds the outer peripheral surface of the contact housing 211 and forms a seal with the housing 100.
[0090] The contact housing 211 provides protection for the conductive spring 212, which is electrically connected to the charging gun by extending out of the contact housing 211. The sealing ring 213 forms a seal with the housing 100 to prevent water on the charging gun from contacting the components inside the charging channel 110 and causing short circuits or other safety risks.
[0091] Furthermore, such as Figure 5 As shown, the high-voltage contact 200 is provided with a temperature detection probe 214, which is located on the side of the sealing ring 213 facing the charging outlet 112. The temperature detection probe 214 is connected to a transmission harness extending toward the charging outlet 112.
[0092] The temperature detection probe 214 can monitor the temperature of the conductive spring 212 in real time. It can respond quickly when the temperature of the conductive spring 212 is too high. Furthermore, the temperature detection probe 214 is located on the side of the sealing ring 213 facing the charging outlet 112, thereby preventing the temperature detection probe 214 from being damaged by contact with water. The transmission harness connected to the temperature detection probe 214 and the high-voltage charging cable 300 extend together to the charging outlet 112 and connect to the vehicle interior, ensuring vehicle charging safety.
[0093] In some specific embodiments of the present invention, the high-voltage contact 200 and the high-voltage wire welding component 310 are connected as one unit by ultrasonic welding or friction welding.
[0094] Ultrasonic welding or friction welding provides a stronger connection than cold pressing, and the current carrying capacity between the high-voltage contact 200 and the high-voltage charging cable 300 is improved after welding to meet the needs of high-current charging.
[0095] In some specific embodiments of the present invention, such as Figure 2 and Figure 4 As shown, the high-voltage contact 200 includes a high-voltage positive contact 201 and a high-voltage negative contact 202, and both the high-voltage positive contact 201 and the high-voltage negative contact 202 are provided with high-voltage contact welding parts 210.
[0096] The high-voltage charging cable 300 includes a high-voltage positive charging cable 301 and a high-voltage negative charging cable 302. Both the high-voltage positive charging cable 301 and the high-voltage negative charging cable 302 are provided with high-voltage wire welding parts 310. The high-voltage contact welding parts 210 of the high-voltage positive contact 201 are welded to the high-voltage wire welding parts 310 of the high-voltage positive charging cable 301, and the high-voltage contact welding parts 210 of the high-voltage negative contact 202 are welded to the high-voltage wire welding parts 310 of the high-voltage negative charging cable 302.
[0097] Both the high-voltage positive contact 201 and the high-voltage negative contact 202 are installed inside the charging channel 110 and exposed from the charging inlet 111. The high-voltage positive contact 201 and the high-voltage negative contact 202 are arranged radially at intervals along the charging channel 110 to accommodate the charging gun's contact charging.
[0098] In some specific embodiments of the present invention, such as Figure 2 As shown, the vehicle charging dock 1 also includes a low-voltage contact 700 and a low-voltage charging cable 800.
[0099] The low-voltage contact 700 is installed in the charging channel 110 via the pressure plate 400 and protrudes from the charging inlet 111. The low-voltage charging cable 800 extends into the charging channel 110 from the charging outlet 112 and is connected to the low-voltage contact 700.
[0100] By incorporating low-voltage contact 700 and low-voltage charging cable 800, the system adapts to different charging modes. When fast charging is required, it matches with high-voltage contact 200 for rapid charging. During low-voltage charging, it matches with low-voltage contact 700 for slow charging, thus protecting the vehicle charging socket 1.
