Description

Technical Field

[0001] This invention belongs to the field of automotive technology, specifically relating to an automotive charging port cover assembly and an electric vehicle. Background Technology

[0002] Electric vehicles are cars powered by onboard electricity. In recent years, with the continuous improvement of people's living standards, cars have gradually entered ordinary households and become a means of transportation for many people. At the same time, the increasing emissions from natural gas have polluted the environment. Under the background of environmental protection departments advocating green and environmentally friendly practices, electric vehicles for various purposes have emerged.

[0003] The car charging port cover is a component that conceals and protects the car's charging port, creating a dry and enclosed environment for it. Currently, the buffer structure used in charging port covers when opened to their maximum angle is a direct impact type, which uses a mechanism to impact a rubber buffer block for cushioning. This results in a large instantaneous impact force, causing the charging port cover to vibrate and make a loud impact noise when it opens to its maximum position. Summary of the Invention

[0004] In view of this, the purpose of the present invention is to provide an automotive charging port cover assembly, which aims to solve the technical problems of existing automotive charging port covers being prone to shaking and loud impact noise when opened.

[0005] To achieve the above objectives, the present invention provides the following technical solution: an automotive charging port cover assembly, comprising a base having a charging port, a cover rotatably disposed on the base and used to open or close the charging port, and a rotating arm assembly disposed on one side of the base and used to drive the cover to rotate toward or away from the base. The rotating arm assembly includes a hollow housing and a rotating arm rotatably mounted at one end in the housing. The other end of the rotating arm is connected to the cover. At least one buffer is provided on the rotating arm, and the buffer is used to squeeze the housing during the rotation of the rotating arm.

[0006] Furthermore, the housing includes a first housing body for defining the travel of the rotating arm, and a second housing body disposed opposite to both ends of the first housing body, wherein the first housing body and the two second housing bodies enclose a receiving cavity for one end of the rotating arm to extend into.

[0007] Furthermore, there are two buffer components, and there is a gap between each of the two second shell bodies and the rotating arm, with each buffer component placed in the gap.

[0008] Furthermore, along the height direction of the rotating arm, the sum of the height of the rotating arm and the height of the two buffer members is greater than the distance between the two second shell bodies.

[0009] Furthermore, the thickness of the second shell body is gradually reduced along the closing direction of the cover.

[0010] Furthermore, the buffer includes a concave pad and a boss disposed in the pad, and the rotating arm has a slot for inserting the boss at the position of the boss.

[0011] Furthermore, the rotating arm is provided with a receiving groove for accommodating the pad.

[0012] Furthermore, one end of the rotating arm is installed in the first housing body via a rotating shaft, and both ends of the rotating shaft extend out of the first housing body. One of the second housing bodies is provided with a torsion spring assembly for elastically pulling the rotating shaft to rotate.

[0013] Furthermore, the torsion spring assembly includes a connector disposed on the second housing body and sleeved on the rotating shaft, and a torsion spring connected at one end to the connector. The second housing body is provided with a fixing platform for fixing the other end of the torsion spring.

[0014] This application also provides an electric vehicle, including a body, wherein a charging port cover assembly is provided inside the body, the charging port cover assembly being the automobile charging port cover assembly as described above.

[0015] The beneficial effects of the present invention are as follows: Compared with the prior art, the car charging port cover assembly of the present invention has at least one buffer on the rotating arm, so that when the rotating arm drives the cover to rotate, the rotating arm drives the buffer to rotate and continuously squeeze the shell. When the cover is opened to the maximum angle, the shell and the buffer are continuously pressed together, realizing linear absorption of impact energy. The cover will not shake when it is opened to the maximum position, and there is no obvious impact sound, which improves the user's comfort.

[0032] like Figures 1-7As shown, this embodiment proposes an automotive charging port cover assembly, including a base (not shown in the figure) with a charging port. A cover 1 is rotatably mounted on the base. The cover 1 can be used to open or close the charging port. A rotating arm assembly 2 is provided on one side of the base. The rotating arm assembly 2 can be used to drive the cover 1 to rotate toward or away from the base. Specifically, the rotating arm assembly 2 includes a housing 21 and a rotating arm 22. The housing 21 is hollow inside. One end of the rotating arm 22 is rotatably mounted in the housing 21, and the other end of the rotating arm 22 is connected to the cover 1. In addition, at least one buffer 3 is provided on the rotating arm 22. The buffer 3 can be used to squeeze the housing 21 during the rotation of the rotating arm 22. In this way, by making the interior of the housing 21 hollow, one end of the rotating arm 22 can be installed in the housing 21; by providing at least one buffer 3 on the rotating arm 22, when the rotating arm 22 drives the cover 1 to rotate, the rotating arm 22 drives the buffer 3 to rotate and continuously squeeze the housing 1. When the cover 1 is opened to the maximum angle, the housing 1 and the buffer 3 are continuously pressed together, realizing linear absorption of impact energy. The cover 1 will not shake when it is opened to the maximum position, and there is no obvious impact sound, which improves the user's comfort.

[0033] In this invention, when the cover 1 is fastened onto the base, it is in the initial state, and the buffer 3 is located in the housing 21. As the rotating arm 22 rotates, it drives the cover 1 to open the charging port, and at the same time, it drives the buffer 3 to rotate together, so that the buffer 3 continuously presses the housing 21. When the cover 1 is opened to the maximum position, the buffer 3 just moves to the opening position of the housing 21, realizing that the rotating arm 22 is in close contact with the cover 1 throughout the rotation process, preventing the cover 1 from shaking during rotation.

[0034] Preferably, the rotating arm 22 is arranged in an arc shape that bulges outward toward the charging port. By setting it in an arc shape, the entire automotive charging port cover assembly structure becomes more compact. Of course, in this embodiment, the rotating arm can also be arranged in other shapes according to actual conditions and specific needs, and is not limited here.

[0035] Further, please refer to Figure 2 and Figure 3The housing 21 includes a first housing body 211 for defining the travel of the rotating arm 22, and second housing bodies 212 disposed opposite to each other at both ends of the first housing body 211. The first housing body 211 and the two second housing bodies 212 form a receiving cavity 213 for one end of the rotating arm 22 to extend into. Preferably, the first housing body 211 is arc-shaped, which better adapts to the rotation travel of the rotating arm 22. In this application, the first housing body 211 and the two second housing bodies 212 are integrally formed, which simplifies subsequent machining and reduces costs. Of course, the first housing body 211 and the two second housing bodies 212 can also be detachably connected, such as by snap-fit ​​connections, etc., which is not the only limitation here.

[0036] Further, please refer to Figure 1 and Figure 3 There are two buffer elements 3. There are gaps between the two second shell bodies 212 and the rotating arm 22, and each buffer element 3 is placed in a gap. By setting gaps, it is easy to place the buffer elements 3. By setting two buffer elements 3, it is beneficial to enhance the compressive force between the rotating arm 22 and the shell 21, so as to achieve a tight contact between the shell 21, the buffer elements 3 and the rotating arm 22, and prevent the cover 1 from shaking and producing obvious impact noise during rotation.

[0037] Preferably, along the height direction of the rotating arm 22, the sum of the height of the rotating arm 22 and the height of the two buffer members 3 is greater than the distance between the two second shell bodies 212. This ensures that the buffer members 3 can continuously press against the second shell bodies 212, achieving better linear absorption of impact energy. Specifically, the distance between the two second shell bodies 212 can be 10cm, 12cm, 14cm, 16cm, 18cm, 20cm, etc., and correspondingly, the sum of the height of the rotating arm 22 and the height of the two buffer members 3 can be 10.5cm, 12.5cm, 14.5cm, 16.5cm, 18.5cm, 20.5cm, etc., without limitation here.

[0038] Preferably, the thickness of the second shell body 212 is gradually reduced along the closing direction of the cover 21. By setting it to be gradually reduced, the distance between the inner surfaces of the two second shell bodies 212 gradually decreases, so that during the rotation of the buffer 3, the second shell bodies 212 continuously press the buffer 3, thereby achieving the purpose of linearly absorbing the impact energy and making the cover 1 more stable during the opening process.

[0039] Further, please refer to Figures 5 to 7The buffer 3 includes a pad 31 and a boss 32. The pad 31 is concave, and the boss 32 is disposed on the pad 31. The rotating arm 22 has a slot 23 corresponding to the boss 32, and the slot 23 can be inserted through the boss 32. By making the pad 31 concave, it is easy to install the pad 31 on the rotating arm 22; by providing the boss 32 and the slot 23, a stable connection between the rotating arm 22 and the buffer 3 is achieved through the cooperation of the boss 32 and the slot 23.

[0040] Preferably, the pad 31 and the boss 32 are integrally formed.

[0041] Further, please refer to Figure 7 The rotating arm 22 is provided with a receiving groove 24. By providing the receiving groove 24, it is easy to place the pad 31 in it, which increases the stability of the rotating arm 22 and the pad 31, and prevents the buffer 3 from moving during rotation and friction, thus affecting the friction effect.

[0042] Preferably, the depth of the receiving groove 24 is less than the thickness of the pad 31. In this way, while ensuring the stability of the rotating arm 22 and the pad 31, the pad 31 and the second shell body 212 have a large contact area, which improves the friction effect.

[0043] Preferably, the pad 31 is arranged in an inverted cone shape, that is, the smaller end of the pad 31 is placed in the receiving groove 24, and the larger end of the pad 31 abuts against the second shell body 212. In this way, the contact area near the second shell body 212 is larger, resulting in a larger friction area. Of course, in this embodiment, the pad 31 may also be arranged in other shapes, and is not limited here.

[0044] Further, please refer to Figure 3 and Figure 4 One end of the rotating arm 22 is mounted in the first shell body 211 via a rotating shaft 4. Both ends of the rotating shaft 4 extend outside the first shell body 211. One of the second shell bodies 212 is provided with a torsion spring assembly 5 for elastically pulling the rotating shaft to rotate. In this way, the rotating arm 22 can rotate around the rotating shaft 4, and by providing the torsion spring assembly 5, the rotating shaft 4 can be pulled to rotate by the torsion spring assembly 5, thereby quickly achieving the closing of the cover 1.

[0045] Further, please refer to Figure 3 and Figure 4The torsion spring assembly 5 includes a connector 51 and a torsion spring 52. The connector 51 is disposed on the second shell body 212 and sleeved on the rotating shaft 4. One end of the torsion spring 52 is connected to the connector 51. In addition, the second shell body 212 is also provided with a fixing platform 6, and the other end of the torsion spring 52 is connected to the fixing platform 6. Thus, when the cover 1 needs to be closed, the torsion spring 52 pulls the connector 51 to rotate, the connector 51 pulls the rotating shaft 4 to rotate, the rotating shaft 4 in turn drives the rotating arm 22 to rotate, and the rotating arm 22 drives the cover 1 to move towards the charging port, thereby closing the cover.

[0046] This application also provides an electric vehicle, including a body, within which a charging port cover assembly is provided, which is the automotive charging port cover assembly as described above. Other structural features of the electric vehicle are prior art and will not be detailed here.

Although the present invention has been described in detail through the above preferred embodiments, those skilled in the art should understand that various changes can be made to it in form and detail without departing from the scope defined by the claims of the present invention.
