Description

Technical Field

[0001] This utility model relates to the field of vehicle technology, and in particular to a cover assembly and a vehicle. Background Technology

[0002] Many vehicle cover assemblies (such as charging port covers or fuel filler caps) generally include a mounting base and a protective cover. The protective cover can rotate relative to the mounting base to open or close the mounting base, thereby exposing or protecting the components inside the mounting base.

[0003] To improve the smoothness of the protective cover opening and closing process, there is generally a certain gap between the protective cover and the mounting base in the axial direction of the protective cover's rotating shaft. Due to the existence of the gap, the protective cover is prone to wobbling along the axial direction of the rotating shaft after being opened. Utility Model Content

[0004] The main objective of this invention is to provide a cover assembly and vehicle that aims to reduce the swaying of the cover assembly along its own axis of rotation.

[0005] To achieve the above objectives, the cover assembly proposed in this utility model is applied to a vehicle, and the cover assembly includes:

[0006] Seat assembly;

[0007] A cover assembly is rotatably connected to the base assembly, and a gap exists between the cover assembly and the base assembly along the rotation axis of the cover assembly;

[0008] An elastic component is provided in one of the seat assembly and the cover assembly. When the cover assembly rotates to a preset angle range, the elastic component is at least partially located within the gap, and the other of the seat assembly and the cover assembly abuts against the elastic component, causing the elastic component to deform and generate an elastic force along the rotation axis of the cover assembly to limit the size of the gap.

[0009] In one embodiment, the resilient component includes:

[0010] An elastic element is provided in the cover assembly; and

[0011] An abutment is provided at one end of the elastic member opposite to the cover assembly;

[0012] When the cover assembly rotates to a preset angle range, the abutting member is at least partially located within the gap and abuts against the seat assembly, causing the elastic member to deform and generate an elastic force along the rotation axis of the cover assembly, thereby limiting the size of the gap.

[0013] In one embodiment, the cover assembly includes:

[0014] Port cover; and

[0015] A connecting arm has a first end and a second end opposite to each other, the port being covered by the second end, and the first end being rotatably connected to the base assembly;

[0016] The first end is provided with a receiving hole, which extends along the rotation axis of the connecting arm. The elastic element is disposed inside the receiving hole, and the abutting member extends at least partially outside the receiving hole. The abutting member abuts against the seat assembly when the port cover rotates to the preset angle range.

[0017] In one embodiment, the preset angle range is configured such that the angle between the port cover and the base assembly is 80° to 90°.

[0018] In one embodiment, the base assembly is provided with a mounting groove, the first end is rotatably connected to the inner wall of the mounting groove, and the outer wall of the first end is spaced apart from the inner wall of the mounting groove to form the gap.

[0019] The port cover is rotated to the preset angle range, causing the abutment to abut against the inner wall of the mounting groove; the port cover is rotated to outside the preset angle range, causing the abutment to separate from the inner wall of the mounting groove.

[0020] In one embodiment, the gap is greater than or equal to 0.5 mm.

[0021] In one embodiment, the first end is further provided with an assembly hole, the assembly hole communicating with the receiving hole, and the abutting member and the elastic member being installed into the receiving hole through the assembly hole; and / or,

[0022] The periphery of the receiving hole is provided with a limiting structure, which is used to prevent the abutment from disengaging from the receiving hole.

[0023] In one embodiment, the abutment is a ball bearing.

[0024] In one embodiment, the elastic component is provided on both opposite sides of the cover assembly along the rotation axis direction of the cover assembly.

[0025] This utility model also proposes a vehicle including the aforementioned cover assembly.

[0026] The cover assembly of this utility model includes a base assembly, a cover assembly, and an elastic component. The base assembly is opened and closed by rotating the cover assembly. The gap between the cover assembly and the base assembly ensures smooth rotation of the cover assembly. The elastic component is disposed on one of the base assembly and the cover assembly. During the opening and closing of the base assembly, when the cover assembly rotates to a preset angle range, at least a portion of the elastic component is located within the gap between the cover assembly and the base assembly. The other base assembly and cover assembly abuts against the elastic component, causing the elastic component to be supported between the base assembly and the cover assembly and to deform. The deformed elastic component generates a spring force along its own rotation axis. This spring force acts on the base assembly and the cover assembly, allowing the elastic component to support the cover assembly, thereby preventing the gap between the cover assembly and the base assembly from easily changing. Changes caused by factors such as vibration or gravity suppress the swaying of the cover assembly along its own rotation axis when it is within the preset angle range, which helps to extend the service life of the rotational connection between the cover assembly and the seat assembly. When the cover assembly rotates outside the preset angle range, the other part of the seat assembly and the cover assembly will not come into contact with the elastic component. The elastic component does not deform and there is no elastic force applied to the cover assembly and the seat assembly. The normal pressure between the cover assembly and the seat assembly along the rotation axis of the cover assembly is small, which reduces the rotational friction of the cover assembly and ensures smooth rotation of the cover assembly outside the preset angle range.

[0042] This utility model proposes a cover assembly that is applied to vehicles and can be a charging port cover, a fuel filler cap, a windshield washer fluid filler cap, etc. The following description uses energy port covers such as charging port covers or fuel filler caps as examples.

[0043] Please see Figures 1 to 3 , Figure 1 A schematic diagram of the structure of an embodiment of the cover assembly provided by this utility model. Figure 1 , Figure 2 A schematic diagram of the structure of an embodiment of the cover assembly provided by this utility model. Figure 2 , Figure 3 for Figure 2 A magnified view of a portion of point A in the middle.

[0044] In one embodiment of this utility model, the cover assembly includes:

[0045] Seat assembly 100;

[0046] The cover assembly 200 is rotatably connected to the seat assembly 100, and there is a gap between the cover assembly 200 and the seat assembly 100 along the rotation axis of the cover assembly 200.

[0047] One of the elastic component 300, the seat component 100, and the cover component 200 is provided with an elastic component 300. When the cover component 200 rotates to a preset angle range, the elastic component 300 is at least partially located within the gap, and the other of the seat component 100 and the cover component 200 abuts against the elastic component 300, causing the elastic component 300 to deform and generate an elastic force along the rotation axis of the cover component 200 to limit the size of the gap.

[0048] The cover assembly in the technical solution of this utility model includes a seat assembly 100, a cover assembly 200, and an elastic assembly 300. The seat assembly 100 is opened and closed by rotating the cover assembly 200. The gap between the cover assembly 200 and the seat assembly 100 ensures the smoothness of the rotation of the cover assembly 200. An elastic component 300 is disposed on one of the seat assembly 100 and the cover assembly 200. During the opening and closing of the seat assembly 100, when the cover assembly 200 rotates to a preset angle range, at least a portion of the elastic component 300 is located within the gap between the cover assembly 200 and the seat assembly 100. The other seat assembly 100 and the cover assembly 200 abut against the elastic component 300, causing the elastic component 300 to be supported between the seat assembly 100 and the cover assembly 200 and to deform. The deformed elastic component 300 generates a spring force along its own rotation axis. This spring force acts on the seat assembly 100 and the cover assembly 200, allowing the elastic component 300 to support the cover assembly 200, thereby ensuring that the cover assembly 200 and the seat assembly 100 are properly aligned. The gap size between them is not easily changed by factors such as vibration or gravity, which suppresses the swaying of the cover assembly 200 along its own rotation axis when it is within the preset angle range. This helps to extend the service life of the rotational connection between the cover assembly 200 and the seat assembly 100. When the cover assembly 200 rotates outside the preset angle range, the other part of the seat assembly 100 and the cover assembly 200 will not come into contact with the elastic component 300. The elastic component 300 does not deform and there is no elastic force applied to the cover assembly 200 and the seat assembly 100. The normal pressure between the cover assembly 200 and the seat assembly 100 along the rotation axis of the cover assembly 200 is small, which makes the rotational friction of the cover assembly 200 small, thus ensuring the smooth rotation of the cover assembly 200 when it is outside the preset angle range.

[0049] Specifically, in this embodiment, taking the cover assembly as an example of an energy port 101 cover, the base assembly 100 is provided with a mounting cavity 102 and a mounting port connecting the mounting cavity 102 to the external environment. The energy port 101 is provided inside the mounting cavity 102. The cover assembly 200 can open the mounting port by rotating to expose the energy port 101, or close the mounting port to protect the energy port 101. At this time, the rotation axis of the cover assembly 200 is generally perpendicular to or close to the ground. By setting the elastic component 300, the swaying of the cover assembly 200 along its own rotation axis is suppressed, that is, the up-and-down swaying of the cover assembly 200 is reduced.

[0050] The elastic component 300 can be disposed on the cover assembly 200. When the cover assembly 200 rotates to a preset angle range, the elastic component 300 abuts against the seat assembly 100 and deforms. Alternatively, the elastic component 300 can be disposed on the seat assembly 100. When the cover assembly 200 rotates to a preset angle range, the elastic component 300 abuts against the cover assembly 200 and deforms.

[0051] The elastic component 300 is a structure that enables elastic deformation. It can be made using structures such as springs or elastic arms, or using elastic materials such as rubber or polyurethane.

[0052] In one embodiment, the elastic component 300 includes:

[0053] Elastic element 310 is provided on cover assembly 200; and

[0054] The abutment 320 is located at one end of the elastic member 310 away from the cover assembly 200;

[0055] When the cover assembly 200 rotates to a preset angle range, the abutment 320 is at least partially located within the gap and abuts against the seat assembly 100, causing the elastic member 310 to deform and generate elastic force along the rotation axis of the cover assembly 200, thereby limiting the size of the gap.

[0056] Reference Figure 3 and Figure 4 In an embodiment of this utility model, the elastic component 300 includes an elastic element 310 and an abutment element 320. The elastic element 310 can deform when the cover assembly 200 rotates to a preset angle range, generating elastic force. The elastic element 310 is disposed on the cover assembly 200, and the abutment element 320 at the end of the elastic element 310 is responsible for contacting the seat assembly 100. The entire elastic component 300 has a simple structure and is easy to manufacture. The contact using the abutment element 320 also avoids wear on the elastic element 310, which helps to extend the service life of the elastic element 310.

[0057] In one embodiment, the cover assembly 200 includes:

[0058] Port cover 220; and

[0059] The connecting arm 210 has a first end and a second end opposite to each other, with a port cover 220 disposed at the second end, and the first end rotatably connecting to the seat assembly 100.

[0060] The first end is provided with a receiving hole 211, which extends along the rotation axis of the connecting arm 210. An elastic member 310 is provided inside the receiving hole 211, and an abutment member 320 extends at least partially outside the receiving hole 211. The abutment member 320 abuts against the seat assembly 100 when the port cover 220 rotates to a preset angle range.

[0061] Combination Figures 2 to 3 In an embodiment of this utility model, the cover assembly 200 includes a port cover 220 and a connecting arm 210. The port cover 220 is rotatably connected to the seat assembly 100 via the connecting arm 210, resulting in a simple structure that is easy to implement. An elastic component 300 is installed at the first end of the connecting arm 210 connected to the seat assembly 100. When the port cover 220 rotates to a preset angle range, the elastic component 300 supports the seat assembly 100 and the connecting arm 210, reducing the vertical swaying of the connecting arm 210, and thus reducing the vertical swaying of the port cover 220. Specifically, a receiving hole 211 is provided at the first end of the connecting arm 210, the elastic element 310 is hidden in the receiving hole 211, and the abutment 320 extends out of the receiving hole 211. On the one hand, the connecting arm 210 plays a protective role for the elastic element 310, extending the service life of the elastic component 300; on the other hand, the receiving hole 211 extends along the height direction of the vehicle, playing a guiding role for the deformation of the elastic element 310 and the movement of the abutment 320, ensuring the smooth switching of the elastic component 300 between the two states of supporting the cover component 200.

[0062] In one embodiment, the preset angle range is configured such that the angle between the port cover 220 and the base assembly 100 is 80° to 90°.

[0063] In the embodiments of this utility model, when the port cover 220 is nearly fully open and fully open, the abutment 320 contacts the seat assembly 100 to support the cover assembly 200 and reduce the shaking of the cover assembly 200. Specifically, the preset angle range is that the angle between the port cover 220 and the seat assembly 100 is 80° to 90°.

[0064] Specifically, when the port cover 220 closes the mounting port of the base assembly 100, the angle between the port cover 220 and the base assembly 100 is 0°. At this time, the abutment 320 does not contact the base assembly 100, the elastic element 310 is in its natural state, and the port cover 220 fits tightly with the mounting port, without any up-and-down wobbling. When the port cover 220 is opened and the angle between the port cover 220 and the base assembly 100 is less than 80°, the abutment 320 still does not contact the base assembly 100, and the elastic element 310 remains in its natural state. This helps ensure the smooth rotation of the connecting arm 210 relative to the port cover 220 and avoids jamming when the port cover 220 is opened. When the angle between the port cover 220 and the base assembly 100 reaches 80°, the abutment 320 contacts the base assembly 100, and the elastic element 310 remains in its natural state. This helps ensure the smooth rotation of the connecting arm 210 relative to the port cover 220 and avoids jamming when the port cover 220 is opened. When the elastic component 310 begins to deform under pressure, it generates elastic force. The entire elastic component 300 begins to support the cover assembly 200, reducing the up-and-down swaying of the cover assembly 200, until the angle between the port cover 220 and the seat assembly 100 reaches 90°, that is, the cover assembly 200 is fully open. Conversely, when the cover assembly 200 is closed, while the angle between the port cover 220 and the seat assembly 100 is still between 80° and 90°, the elastic component 300 continues to reduce the up-and-down swaying of the cover assembly 200, until the angle between the port cover 220 and the seat assembly 100 is less than 80°, the abutment 320 and the seat assembly 100 are no longer in contact, the elastic component 310 returns to its natural state, ensuring the smooth rotation of the connecting arm 210 relative to the port cover 220 and preventing the port cover 220 from jamming when closed.

[0065] In one embodiment, the seat assembly 100 is provided with a mounting groove 103, a first end is rotatably connected to the inner wall of the mounting groove 103, and the outer wall of the first end is spaced apart from the inner wall of the mounting groove 103 to form a gap.

[0066] Specifically, when the port cover 220 is rotated to a preset angle range, the abutment 320 abuts against the inner wall of the mounting groove 103; when the port cover 220 is rotated to a position outside the preset angle range, the abutment 320 separates from the inner wall of the mounting groove 103.

[0067] Reference Figure 3In this embodiment of the invention, a mounting groove 103 is provided on the base assembly 100. The first end of the connecting arm 210 is rotatably disposed within the mounting groove 103. When the connecting arm 210 rotates to position the port cover 220 within a preset angle range, the abutment member 320 on the connecting arm 210 enters the mounting groove 103 and abuts against the inner wall of the mounting groove 103, thereby supporting the connecting arm 210 and the port cover 220. When the connecting arm 210 rotates to position the port cover 220 outside the preset angle range, the abutment member 320 on the connecting arm 210 leaves the mounting groove 103, and the elastic component 300 provides no support for the connecting arm 210 and the port cover 220. By providing the mounting groove 103, it is convenient to hide the connecting arm 210 and to determine whether the abutment member 320 abuts against the base assembly 100.

[0068] In one embodiment, the gap is greater than or equal to 0.5 mm.

[0069] Reference Figure 3 In an embodiment of this utility model, along the rotation axis of the connecting arm 210, the distance between the outer wall of the first end and the inner wall of the mounting groove 103 is as follows: Figure 3 As shown at point t, this spacing is not less than 0.5mm, such as 0.5mm, 0.8mm, 1mm, etc., to avoid the situation where the connecting arm 210 does not rotate smoothly relative to the seat assembly 100 due to the spacing being too small, and to reduce the jamming during the opening and closing of the port cover 220.

[0070] In one embodiment, the first end is further provided with an assembly hole 212, which communicates with a receiving hole 211. The abutment member 320 and the elastic member 310 are installed into the receiving hole 211 through the assembly hole 212; and / or,

[0071] The periphery of the receiving hole 211 is provided with a limiting structure 213, which is used to prevent the abutment 320 from disengaging from the receiving hole 211.

[0072] Reference Figure 4 and Figure 5In this embodiment of the invention, the first end of the connecting arm 210 is provided with an assembly hole 212 communicating with the receiving hole 211. During the assembly of the elastic component 300, the abutment 320 is first inserted into the receiving hole 211 through the assembly hole 212, and then the elastic component 310 is compressed through the assembly hole 212 and inserted into the receiving hole 211. After entering the assembly hole 212, the elastic component 310 returns to its natural state, causing the abutment 320 to partially extend out of the receiving hole 211. By providing the assembly hole 212, the assembly difficulty of the elastic component 300 is reduced. Specifically, in this embodiment, the assembly hole 212 is located on the side of the connecting arm 210 facing the interior of the mounting cavity 102, i.e., the assembly hole 212 faces away from the external environment. This allows the connecting arm 210 and the port cover 220 to shield the assembly hole 212, reducing the probability of dust or liquid entering the assembly hole 212, thereby extending the service life of the elastic component 300. Of course, a removable plug can also be installed at the assembly hole 212 to prevent dust, liquid, etc. from entering the assembly hole 212.

[0073] Reference Figure 5 In this embodiment of the invention, a limiting structure 213 is provided around the periphery of the receiving hole 211. The limiting structure 213 can be implemented in the form of a buckle, protrusion, or the like that that cooperates with the abutment 320, thereby preventing the abutment 320 from dislodging from the receiving hole 211 and ensuring the reliability of the elastic component 300. Specifically, in this embodiment, the abutment 320 is a ball bearing. The inner diameter of the receiving hole 211 gradually decreases at the end closest to the external environment, corresponding to the shape of the ball bearing. The gradually decreasing inner diameter of the inner wall forms the limiting structure 213, preventing the ball bearing from dislodging from the mounting hole.

[0074] In one embodiment, the abutment 320 is a ball bearing.

[0075] Reference Figure 3 and Figure 5 In the embodiments of this utility model, when the port cover 220 rotates to a preset angle range, during the process of the abutment 320 abutting against the inner wall of the mounting groove 103, the abutment 320 will move relative to the inner wall of the mounting groove 103 as the connecting arm 210 rotates. Therefore, the abutment 320 adopts a ball bearing form, which changes sliding friction into rolling friction, which helps to reduce friction and improves the smoothness of the movement of the abutment 320 relative to the inner wall of the mounting groove 103. This also improves the smoothness of opening and closing of the cover assembly 200 and extends the service life of the elastic component 300.

[0076] In one embodiment, elastic components 300 are provided on opposite sides of the cover assembly 200 along the rotation axis direction.

[0077] In the embodiments of this utility model, the rotation axis of the cover assembly 200 applied at the energy port 101 is generally perpendicular to or close to the ground. Therefore, elastic components 300 are provided on both the upper and lower sides of the cover assembly 200, which further improves the supporting effect of the elastic components 300 when the cover assembly 200 rotates to a preset angle range and further reduces the up-and-down swaying of the cover assembly 200.

[0078] This utility model also proposes a vehicle including the aforementioned cover assembly. The specific structure of the cover assembly is as described in the above embodiments. Since this vehicle adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be repeated here.

Any equivalent structural transformations made based on the technical concept of the present utility model and the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the scope of protection of the present utility model.
