Description

Technical Field

[0001] This application relates to the field of charging interface technology, specifically to a shell structure and a charging gun head. Background Technology

[0002] An AC vehicle charging gun is a device used to electrically connect the battery pack of a new energy vehicle to the charging socket, thus enabling the charging function of the new energy vehicle. For AC vehicle charging guns, a safety hook needs to be installed, and a button is used to raise and lower the safety hook, thereby securing the charging gun to the charging socket after coupling.

[0003] In most existing AC charging guns for new energy vehicles that use a split design, the button is fixed to the charging gun on the side of the housing using screws or pins, which damages the overall integrity of the housing. Secondly, in order to cover up the mounting holes of the screws or pins, a plug-like part is added for encapsulation, which greatly affects the aesthetics. Utility Model Content

[0004] The purpose of this application is to provide a shell structure and a charging gun head to solve the defect in the prior art where the shell surface is damaged due to conventional button installation.

[0005] To achieve the above objectives, this application employs the following technical solution:

[0006] Firstly, this application discloses a shell structure, which includes...

[0007] Button component;

[0008] A first bracket is rotatably connected to the button assembly, and the first bracket and the button assembly are movable relative to each other about a rotation point;

[0009] The housing has a first connecting part and a second connecting part on the first bracket. The first connecting part and the second connecting part are engaged and fixed to fix the button assembly to the housing.

[0010] In a further embodiment of this application, the button assembly includes a button body and a safety hook that are fixedly connected, and the button body is rotatably connected to the first bracket via a pin.

[0011] In a further embodiment, the first bracket is positioned and fixed inside the housing, and the button body is aligned with the mounting surface of the housing.

[0012] In a further embodiment, the first bracket is provided with a first positioning body, and the housing is provided with a second positioning body. The first positioning body and the second positioning body are mutually constrained and fixed, so that the first bracket and the second positioning body are positioned and installed.

[0013] In a further embodiment, the first bracket is fixed to the housing, and the safety hook protrudes from the end face of the housing.

[0014] In a further embodiment, the first bracket is fixed to the housing, and one end of the button body is flush with one end of the housing.

[0015] In a further embodiment of this application, the button assembly is centrally fixed to the housing.

[0016] Secondly, this application discloses a charging gun head, which includes the aforementioned shell structure.

[0017] The beneficial effects of this application are as follows:

[0018] In this application, the button assembly and the first bracket are pre-rotated and installed, and then the first bracket and the housing are fixed through two joints. This avoids the use of bolts and other connecting parts, ensuring the stable installation of the button assembly while avoiding damage to the overall integrity of the housing due to opening holes in the housing, thus improving the aesthetics of the housing. The first bracket and the housing have a "hidden" joint feature, which completes the "hidden" installation of the button assembly. The housing surface does not need to use blocking parts to encapsulate the corresponding mounting holes, and the device controls costs to a certain extent.

[0019] The first bracket and the housing are equipped with positioning elements to ensure proper positioning and improve installation accuracy. The button body and the first bracket rotate via a pin. During installation, the mounting holes on the button body and the first bracket correspond to each other, and the pin provides axial positioning, thus improving the accuracy of button operation.

Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit this application or its application or use. Example 1

[0027] like Figure 1 and Figure 2 As shown, this embodiment discloses a shell structure that can be used on a charging gun head. This shell structure includes a button assembly 1, a first bracket 3, and a housing 4. The first bracket 3 is rotatably connected to the button assembly 1, and the first bracket 3 and the button assembly 1 can move relative to each other around a rotation point. The housing 4 is provided with a first connecting part, and the first bracket 3 is provided with a second connecting part. The first connecting part and the second connecting part are engaged and fixed to fix the button assembly 1 to the housing 4. Typically, a mounting groove is opened in the housing 4, and the mounting groove is formed during the injection molding of the housing 4. The opening of the mounting groove matches the mounting surface on the first bracket 3. Here, the first bracket 3 is engaged in the mounting groove, which is a type of snap-fit ​​fixation. Other reasonable engaging structures are also acceptable. Typically, the button assembly 1 is fixed in the center on the housing 4 for easy operation by the user.

[0028] In this shell structure, the button assembly 1 and the shell 4 are engaged and fixed by corresponding first and second joints, avoiding the use of connectors (bolts), thereby avoiding the opening of holes such as threaded holes, and eliminating the need for sealing with plug-style parts, ensuring stability while enhancing the aesthetic appearance of the shell 4.

[0029] Observation Appendix Figure 2 In this embodiment, the button assembly 1 includes a button body 11 and a safety hook 12 that are fixedly connected. The button body 11 is rotatably connected to the first bracket 3 via a pin 2, and is equipped with an attached... Figure 4In this embodiment, a boss is provided on one side of the button body 11, and a corresponding slot is provided on the first bracket 3. During production, a shaft hole is opened on the button body 11, which passes through the boss laterally. Another shaft hole is opened on the first bracket 3, which passes through the side wall of the slot on the first bracket 3. Adjacent shaft holes match each other, and all shaft holes are coaxially arranged. The pin 2 passes through the two shaft holes, enabling the button body 11 and the first bracket 3 to rotate around the pin 2. The first bracket 3 is positioned and installed with the housing 4. The first bracket 3 is provided with a first positioning body, which in this embodiment uses a positioning hole as the first positioning body. The housing 4 is provided with a second positioning body, which in this embodiment uses a positioning post as the second positioning body. The first positioning body and the second positioning body are inserted and fixed. Here, the positioning post is aligned with the positioning hole for positioning and guidance, so that the first bracket 3 and the second positioning body are positioned and installed. The button body 11, the pin 2, and the first bracket 3 are installed as a whole on the housing 4. The first bracket 3 is fixed, and the button body 11 can move in the mounting slot. It is worth noting that after the button body 11 is installed, the safety hook 12 at its end protrudes from the end face of the housing 4.

[0030] In a further embodiment, a second bracket 8 is provided below the housing 4, and a micro switch 7 is fixed on the top of the second bracket 8. When in use, the micro switch 7 is intermittently triggered by the tail of the button body 11. The second bracket 8 is fixed on the side of the housing 4 away from the button assembly 1, and an elastic element 6 is fixed between the second bracket 8 and the button body 11. Here, for the sake of installation, a compression spring is used as the elastic element 6. Theoretically, a rubber body with greater elasticity can also be used as the elastic element 6.

[0031] In a preferred embodiment, positioning bosses are provided on the opposite surfaces of the second bracket 8 and the button assembly 1. The two ends of the compression spring are fixed on the positioning bosses. The positioning bosses facilitate the installation of the compression spring and also play a role in accurate positioning. When the user presses the tail of the button body 11, one side of the safety hook 12 is raised. After the button body 11 is released, the safety hook 12 moves down to reset and couples with the charging socket under the drive of the spring's deformation recovery.

[0032] The second bracket 8 and the housing 4 also adopt directional and guiding connection; a guide groove is provided on the inner wall of the housing 4 to guide the second bracket 8 during installation. The guide groove matches the shape of the mounting end on the second bracket 8. In addition, two positioning posts are provided at intervals on the housing 4, and two positioning holes are provided on the second bracket 8 respectively. These serve to position the second bracket 8 when it is installed on the housing 4. To ensure a stable connection, screws 5 are used to lock and fix the first bracket 3, the housing 4, and the first bracket 3.

[0033] This housing 4 is used on the charging gun head. The second bracket 8 has an opening and a cable outlet for cable insertion. The wire on the micro switch 7 first passes through the opening at the front end of the second bracket 8, and then through the cable outlet on the second bracket 8.
