Description

Technical Field

[0001] This utility model relates to the field of automotive connector technology, and in particular to an automotive charging dock. Background Technology

[0002] With social development and improved economic levels, people's awareness of environmental protection has gradually increased, and their demand for low-carbon living and a low-carbon economy has become increasingly strong. The low-carbon economy is a new engine for economic development, and new energy electric vehicles represent a development trend in the automotive industry and a new industry strongly supported by the government.

[0003] New energy vehicles are charged via an external charging gun connected to the charging connector on the vehicle, i.e., the car charging socket. Current technology for vehicle-side charging connectors mostly uses a vertical cable routing structure, meaning the cable is routed parallel to the installation location (see attached diagram). Figure 10 In the X-axis direction (perpendicular to the vehicle body), the charging connector at the vehicle end needs to ensure the conduction of large current, which makes it difficult to reduce the size of the wiring harness connected to the charging connector. The vertical cable exit structure means that the wiring harness needs to occupy a large installation space in the vehicle in the plugging direction, which is easily restricted by the layout of the vehicle's equipment and wiring harness. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides an automotive charging socket with a charging socket that is angled out relative to the mounting base, which significantly reduces the installation space of the charging socket and facilitates the arrangement of the vehicle's wiring harness.

[0005] This utility model is achieved through the following technical solution:

[0006] A car charger socket for inserting a charging gun, the car charger socket including a first socket, the first socket including:

[0007] case;

[0008] A docking terminal is disposed inside the housing and is used to dock with the terminal components in the charging gun;

[0009] A first adapter piece is disposed inside the housing, with one end of the first adapter piece connected to a cable and the other end fixedly connected to the mating terminal;

[0010] The cable's axial direction is inclined to the axial direction of the mating terminal.

[0011] Furthermore, the first adapter piece is integrally formed with a first part and a second part that is inclined to the first part. The first part is fixedly connected to the docking terminal, and the second part is fixedly connected to the cable.

[0012] Furthermore, the first part is fixedly connected to the mating terminal by a first bolt.

[0013] Furthermore, the housing includes a protective shell, on which a first chamber and a second chamber are formed at an angle to the first chamber are formed. The mating terminal and the first part are at least partially housed in the first chamber, and the cable and the second part are at least partially housed in the second chamber.

[0014] Furthermore, the protective shell is provided with a first opening, through which a locking tool can tighten or loosen the first bolt.

[0015] Furthermore, the first socket also includes a grounding terminal and a second adapter piece, one end of the second adapter piece being connected to the grounding terminal via a second bolt, and the other end being connected to a ground wire.

[0016] Furthermore, a third chamber is formed on the protective shell, which is perpendicular to the first chamber, and the ground wire and the second adapter piece are at least partially accommodated in the third chamber.

[0017] Furthermore, the protective shell is provided with a second opening, through which a locking tool can tighten or loosen the second bolt.

[0018] Furthermore, the first socket also includes a plurality of sealing elements disposed in the protective housing, wherein a limiting platform is formed in the protective housing, and the sealing elements abut against the limiting platform.

[0019] Furthermore, the first socket also includes a second protective cover, which is fixed to the protective shell and used to cover the first opening and the second opening.

[0020] Compared with existing technologies, the advantages of this utility model are:

[0021] 1. This utility model connects the cable and the docking terminal by setting a first connecting piece, and simultaneously setting a first part and a second part with a certain tilt angle, so that the cable can exit at an angle relative to the mounting base. The charging base is installed inward into the vehicle body. Compared with a charging base with vertical cable routing, the cable is thicker and inconvenient to bend, and the cable occupies more space in the direction perpendicular to the vehicle body, resulting in a lot of unused space around the charging base and low utilization of the vehicle interior space. The charging base with angled cable routing allows the cable to be accommodated on the side of the vehicle body, using the remaining installation space of other automotive components, which significantly reduces the installation space of the charging socket, facilitates the layout of the vehicle wiring harness, and improves the utilization of the vehicle interior space.

[0034] Reference Figures 1 to 9 This utility model discloses an automotive charging dock according to an embodiment of the present invention, comprising a mounting base 1 and at least one socket component. The mounting base 1 is detachably connected to the vehicle body, and the at least one socket component is detachably connected to the mounting base 1. The socket component integrates terminals such as a mating terminal 21, a grounding terminal 22, and a signal terminal 23 for connection to a charging gun. This utility model, through the modular design of the socket component and the mounting base 1, allows the vehicle body to be designed according to the standardized mounting base 1, achieving standardization of the production process and reducing design costs. In this embodiment, the mounting base 1 is provided with four mounting holes 19, through which fixing screws (not shown) can pass to detachably mount the mounting base 1 to the vehicle body.

[0035] Specifically, refer to Figure 3 The socket component also includes a housing 20, on which mating terminals 21, grounding terminals 22, and signal terminals 23 are integrated. A corresponding mounting station 10 is integrally formed on the mounting base 1. At least one mounting station 10 is provided, and each mounting station 10 corresponds to at least one socket component. The housing 20 is detachably mounted at the mounting station 10. The other end of the signal terminal 23 is connected to a signal line 26 to transmit control signals.

[0036] In this embodiment, at least one installation station 10 includes a first installation station 101 and a second installation station 102, and at least one socket includes a first socket 2a and a second socket 2b. The first socket 2a and the second socket 2b are detachably installed in the first installation station 101 and the second installation station 102, respectively. The mounting base 1 can be configured with different positions and numbers of installation stations 10 according to actual needs, enabling it to adapt to more vehicle models.

[0037] Specifically, the mounting base 1 has a plurality of fixing posts 12, and the housing 20 and the locking assembly 3 each have a fixing platform 13 corresponding to one of the fixing posts 12. The fixing platform 13 is detachably connected to the fixing posts 12. In this embodiment, four fixing platforms 13 are formed around the first mounting position 101 and the second mounting position 102. The fixing platform 13 has a first screw hole 14, and the fixing post 12 has a second screw hole 15. The screw 16 passes through the first screw hole 14 and the second screw hole 15 to fix the fixing platform 13 to the fixing post 12, thereby installing the socket component on the mounting base 1. By additionally setting the fixing platform 13 and fixing posts 12 and fixing them with screws 16, the first socket 2a and the second socket 2b can be more securely installed on the mounting base 1, improving the stability of the installation between the socket component and the charging base, and also playing a positioning role during installation.

[0038] Optionally, the mounting base 1 has a number of sockets for connecting to the charging gun. More specifically, the bottom wall of the mounting station 10 has sockets, and the docking terminal 21, grounding terminal 22 and signal terminal 23 are respectively arranged in the number of sockets to connect with the terminal components in the charging gun.

[0039] Optionally, the car charging base also includes a first protective cover 11, which is movable at one end of the mounting base 1 away from the mounting position 10 to protect the exposed parts such as the docking terminal 21, the grounding terminal 22, and the signal terminal 23.

[0040] Optionally, the car charging dock also includes a locking component 3. In this embodiment, the locking component 3 is an electronic lock, which can drive the push rod 30 inside the locking component 3 to extend and lock the charging gun when it is connected. The specific structure of the electronic lock is existing technology and will not be described in detail here. A third mounting position 103 is also formed on the mounting base 1, and the locking component 3 is detachably disposed at the third mounting position 103. In this example, the mounting base 1 is provided with a first mounting position 101, a second mounting position 102, and a third mounting position 103, which are used to install the first socket 2a, the second socket 2b, and the locking component 3, respectively, and the first mounting position 101, the second mounting position 102, and the third mounting position 103 are arranged sequentially along a straight line. In other alternative embodiments, one or more of the first mounting position 101, the second mounting position 102, and the third mounting position 103 can also be selected and disposed in different positions to adapt to different car bodies and reduce design and production costs.

[0041] Specifically, refer to Figure 5 , Figure 6 The first socket 2a includes a housing 20, a mating terminal 21, and a first adapter piece 24. Both the mating terminal 21 and the first adapter piece 24 are disposed within the housing 20. The mating terminal 21 is used to mate with the terminal components in the charging gun, and one end of the first adapter piece 24 is connected to a cable 2c, while the other end is fixedly connected to the mating terminal 21.

[0042] It is worth noting that the axial direction of cable 2c is inclined to the axial direction of the mating terminal 21. This allows cable 2c to exit from a direction perpendicular to the interface and be installed inside the vehicle body, enabling the side of the vehicle body to be utilized for installation and saving installation space.

[0043] Optionally, the first adapter piece 24 is integrally formed with a first part 241 and a second part 242 inclined to the first part 241. The first part 241 is fixedly connected to the mating terminal 21, and the second part 242 is fixedly connected to the cable 2c. By connecting the cable 2c and the mating terminal 21 through the first adapter piece 24, the cable 2c can be better electrically connected to the mating terminal 21, improving product stability.

[0044] Optionally, the first part 241 is fixedly connected to the mating terminal 21 by the first bolt 27a. This makes the product easier to assemble, and the first bolt 27a is a standard part, resulting in lower cost.

[0045] Optionally, the housing 20 includes a protective shell 202, on which a first chamber 203 and a second chamber 204 inclined to the first chamber 203 are formed. The mating terminal 21 and the first part 241 are at least partially accommodated in the first chamber 203, and the cable 2c and the second part 242 are at least partially accommodated in the second chamber 204. This protects the cable 2c during installation, preventing loosening or other adverse effects.

[0046] In addition, the housing 20 also includes a base 201, on which a mounting portion matching the mounting station 10 is formed, which can be inserted into the groove forming the mounting station 10.

[0047] Optional, refer to Figure 4 The protective shell 202 also has a first opening 20a, through which a locking tool can tighten or loosen the first bolt 27a. In this embodiment, the first chamber 203 is vertically upward, allowing the locking tool to pass vertically through the first opening 20a to tighten or loosen the first bolt 27a, making installation more convenient. Furthermore, after installation, the first bolt 27a is at least partially contained within the first chamber 203, reducing the possibility of loosening due to friction or other reasons, and improving product stability.

[0048] Optionally, the first socket 2a further includes a grounding terminal 22 and a second adapter piece 25. One end of the second adapter piece 25 is connected to the grounding terminal 22 via a second bolt 27b, and the other end is connected to a ground wire 220. In this embodiment, the second adapter piece 25 is integrally formed into an elongated shape, so that the ground wire 220 can be perpendicular to the interface.

[0049] Optional, refer to Figure 3 and Figure 9 A third chamber 205 is formed on the protective shell 202, which is perpendicular to the first chamber 203. The ground wire 220 and the second adapter piece 25 are at least partially accommodated in the third chamber 205, thereby protecting the ground wire 220 and preventing poor contact.

[0050] Optionally, refer to Figure 4 The protective shell 202 also has a second opening 20b, through which a locking tool can be passed to tighten or loosen the second bolt 27b. This makes the product easier to assemble, and since the second bolt 27b is a standard part, the cost is lower.

[0051] Further reference Figure 8 and Figure 9 The first socket 2a also includes a plurality of sealing elements 28 disposed in the protective housing 202, and a limiting platform 29 is formed in the protective housing 202, with the sealing elements 28 abutting against the limiting platform 29. This keeps the inside of the housing 20 in a sealed state, reducing oxidation or water ingress of the internal components.

[0052] In this embodiment, a plurality of sealing elements 28 include a sealing gasket 280 and a sealing ring 281. The sealing gasket 280 is disposed in the first chamber 203 to protect the first bolt 27a and the second bolt 27b. The sealing ring 281 is disposed in the second chamber 204 and the third chamber 205 and is sleeved on the cable 2c and the ground wire 220 to prevent dust or water from entering the charging socket.

[0053] Optionally, the first socket 2a also includes a second protective cover 17 disposed on the protective shell 202. In this embodiment, the second protective cover 17 is snap-fitted onto the outlet of the third chamber 205, which can protect the seal 28 and play a certain role in preventing dust.

[0054] This utility model connects the cable 2c and the docking terminal 21 by setting a first connecting piece, and simultaneously setting a first part 241 and a second part 242 with a certain tilt angle, so that the cable 2c can exit at an angle relative to the mounting base 1. The charging base is installed inwards within the vehicle body. Compared to a charging base with vertical wiring, the cable 2c is thicker and inconvenient to bend, occupying more space perpendicular to the vehicle body, resulting in a lot of unused space around the charging base and low utilization of interior space. The angled cable exit charging base allows the cable 2c to be accommodated in the side of the vehicle body, utilizing the remaining installation space from other automotive components, significantly reducing the installation space of the charging socket, facilitating the overall wiring harness layout, and improving the utilization of interior space. For details, please refer to... Figure 10 The dotted line in the diagram represents the vertical cable 2c, and the boxed area indicates the installation range.

[0055] Furthermore, this utility model designs a modular socket component, a base 201, and a mounting seat 1 that mates with the base 201. By setting up a standardized base 201 and mounting seat 1, and selecting the installation position of the socket component on the mounting seat 1 according to the vehicle body, the vehicle body can be designed based on the standardized base 201 and mounting seat 1, thereby achieving standardization of the production process and reducing design costs.

[0056] The above embodiments only illustrate several implementation methods of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
