Description

Technical Field

[0001] This application relates to the field of vehicle parts, and in particular to a power supply cover assembly and a vehicle. Background Technology

[0002] Vehicle cabins typically have a 12V power outlet to power external electrical devices, such as car phones, portable DVD players, and mobile phones. To enhance the interior comfort, the 12V power outlet usually has a cover that conceals the outlet when not connected to external devices. Opening the cover allows external devices to be plugged into the 12V outlet.

[0003] Please refer to Figure 1 Currently, the power cover 1' is connected to the mounting base 4' via a pivot 2' and a torsion spring 3', and the mounting base 4' is fixed to the vehicle body. Under normal conditions, the power cover 1' is fastened to the interface position to cover the interface. When an external force is applied, allowing the power cover 1' to rotate from the interface-covering position to the open position, the torsion spring 3' is compressed, generating a restoring force. When the external force acting on the power cover is removed, the power cover 1' returns to the interface-covering position under the restoring force of the torsion spring.

[0004] In this structure, the restoring force on the torsion spring 3' is always present during the opening of the power cover 1', causing the 12V power cover 1' to automatically retract and block. When plugging in the 12V power supply, it is impossible to operate with one hand. One hand is needed to hold the power cover 1' against the spring to prevent it from rebounding, while the other hand plugs in the power supply, which is inconvenient.

[0005] In addition, when the 12V power cover 1' automatically closes under the action of spring force, the impact between the power cover 1' and the mounting base 4' is quite loud, resulting in a poor perceived quality.

[0006] Overcoming at least one of the above-mentioned defects is a technical problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0007] The purpose of this application is to provide a power cover assembly that is easy to open and reduces noise when closing. Another purpose of this application is to provide a vehicle having the above-mentioned power cover assembly.

[0008] This application provides a power supply cover assembly, including:

[0009] The mounting body has an opening;

[0010] A cover body is frictionally rotatably connected to the mounting body so that the cover body can be in a suspended state during rotation relative to the mounting body, and the cover body rotates relative to the mounting body to open or close the opening.

[0011] Compared with the prior art which uses torsion springs as the restoring force of the cover, in the embodiment of this application, the mounting body and the cover rotate by friction. Under the action of static friction, the cover can be suspended at any position during the opening or closing process. This allows the cover to be opened with one hand, making it convenient to open. Furthermore, when the cover closes the opening, it avoids collision between the cover and the mounting body, which can greatly reduce the occurrence of abnormal noise and improve the overall quality of the vehicle.

[0012] In one example, the device further includes a rotating shaft, with the mounting body circumferentially limited to the rotating shaft and the cover rotatably connected to the rotating shaft; or, the cover is circumferentially limited to the rotating shaft and the mounting body is rotatably connected to the rotating shaft.

[0013] Alternatively, it may also include a rotating shaft, with the mounting body and the rotating shaft being frictionally rotatably connected, and the cover body and the rotating shaft also being frictionally rotatably connected.

[0014] In one example, the mounting body has a first through hole, the cover has a second through hole, and the rotating shaft is located inside the first through hole and the second through hole. One of the first through hole and the second through hole is interference-fitted with the rotating shaft to limit circumferential movement, while the other rotates with friction against the rotating shaft.

[0015] In one example, the shaft is a hollow shaft with an axially extending gap in its peripheral wall to allow adjustment of the shaft's diameter under external force.

[0016] In one example, the mounting body has a first surface with a recess, the opening is disposed on the bottom wall of the recess, the pivot is disposed on the side of the mounting body opposite to the first surface, the recess also has a clearance channel, the cover includes a cover body and a connector, the second connecting end of the connector is connected to the side of the cover body facing the opening, the first connecting end of the connector passes through the clearance channel and is connected to the pivot, and when the cover is in a state of blocking the opening, the cover body is at least partially located in the recess.

[0017] In one example, the connector further has a protrusion located between the first connecting end and the second connecting end, the protrusion extending axially along the pivot, and when the cover is in the fully open opening state, the protrusion engages with the bottom wall of the recessed portion with a clearance fit.

[0018] In one example, the protrusion has a groove with the opening facing away from the pivot, and the groove is located between the two end faces of the protrusion along the axial direction of the pivot.

[0019] In one example, the second connecting end of the connector has a notch, the opening of the notch facing the cover body, and at least one end of the notch along the axial direction of the rotating shaft is a closed end.

[0020] Alternatively / and, the connector is hook-shaped, with the second connector bent toward the cover body.

[0021] In one example, a support wall is also connected to the side of the cover body facing the opening. When the cover body is in the state of blocking the opening, the support wall is located outside the opening, and the support wall abuts against or has a predetermined gap with the bottom wall of the recess.

[0022] In one example, the support wall includes a skeleton body and an elastic body, the elastic body being disposed at least on the end face of the skeleton body facing the bottom wall, the elastic body abutting against the bottom wall of the recess or having a predetermined gap.

[0023] In one example, the end face of the elastomer away from the cover body has a protrusion, which contacts the bottom wall of the recess when the cover body is in a state of blocking the opening.

[0024] This application also provides a vehicle, including a vehicle body and the power cover assembly described in any of the above embodiments.

[0025] The vehicle in this embodiment has the aforementioned power cover assembly, and therefore also has the aforementioned technical effects of the power cover assembly. Attached Figure Description

Those skilled in the art should understand that the power cover assembly provided in the embodiments of this application can also be applied to other application environments and achieve the same or equivalent technical effect as this application.

[0046] This application provides a vehicle with a body, wheels underneath the body, and a cabin. The cabin typically houses a power supply unit for providing power to electrical devices outside the vehicle. These electrical devices are not limited to car phones, portable DVDs, or mobile phones, but can also be other devices. The power supply unit typically operates at 12V, but can also operate at other voltage values, such as 24V.

[0047] This application also provides a power supply cover assembly, including a mounting body 1, a cover body 2, and a rotating shaft 3. The mounting body 1 is mounted on a vehicle body and can be part of an internal component of the vehicle body or a separately installed component. The mounting body 1 has an opening 11 through which external electrical devices can connect to the power supply component; that is, the opening 11 is a connector between the power supply component and the external electrical device. The size and shape of the opening 11 are not limited herein. Figure 2 The image shows one embodiment where the opening 11 is a circular through hole.

[0048] In one embodiment, one of the mounting body 1 and the cover 2 is circumferentially limited to the rotating shaft 3. A circumferentially limited connection means that the two cannot rotate relative to each other in the circumferential direction. There are various ways to achieve a circumferentially limited connection, such as a fixed connection, an interference fit between the shaft and hole, or a keyed connection. This application later provides a method of achieving circumferential limitation through an interference fit. The other of the mounting body 1 and the cover 2 is frictionally rotatably connected to the rotating shaft 3 so that the cover 2 can remain suspended during rotation relative to the mounting body 1. That is, the shaft and hole can rotate relative to each other, and the static friction generated between them allows the rotating body with the shaft and hole to remain suspended.

[0049] In this embodiment, the mounting body 1 is a plastic part, and the cover 2 can be a relatively wear-resistant metal part. In this embodiment, the mounting body 1 can be fixedly connected to the rotating shaft 3, and the cover 2 is frictionally rotatably connected to the rotating shaft 3. The cover 2 reciprocates relative to the rotating shaft 3 to open and close the opening 11. This can minimize the wear of the rotating shaft 3 on the mounting body 1.

[0050] Of course, the rotating shaft 3 can also be fixed to the cover 2, and the rotating shaft 3 can rotate by friction with the mounting body 1. By strengthening the position of the rotating shaft 3 on the mounting hole, the same technical effect as above can also be achieved.

[0051] Furthermore, in one embodiment, the mounting body 1 and the cover 2 may not rotate through the rotating shaft 3. For example, the mounting body 1 and the cover 2 may rotate directly through friction or through other intermediate parts.

[0052] Of course, in another embodiment, the mounting body 1 and the rotating shaft 3 can be connected by frictional rotation, and the cover 2 and the rotating shaft 3 can also be connected by frictional rotation. The maximum static friction force F1 between the mounting body 1 and the rotating shaft 3 can be different from the maximum static friction force F2 between the cover 2 and the rotating shaft 3. For example, F1 is greater than F2. When the force applied by the operator to the cover 2 is between F2 and F1, the cover 2 will rotate relative to the rotating shaft 3 to open or close the opening 11, while the positions of the mounting body 1 and the rotating shaft 3 are relatively fixed. Alternatively, F1 is less than F2. When the force applied by the operator to the cover 2 is between F2 and F1, the position of the cover 2 relative to the rotating shaft 3 is fixed, and the rotating shaft 3 will rotate relative to the mounting body 1 to open or close the opening 11.

[0053] Compared with the prior art which uses torsion springs as the restoring force of the cover, in this embodiment, the mounting body 1 and the cover 2 rotate by friction. Under the action of static friction, the cover 2 can be suspended at any position during the opening or closing of the opening 11. This allows the cover 2 to be opened with one hand, making it convenient to open. Furthermore, when the cover 2 closes the opening 11, it avoids collision between the cover 2 and the mounting body 1, which can greatly reduce the occurrence of abnormal noise and improve the overall quality of the vehicle.

[0054] In the above embodiments, by setting the rotating shaft 3 to rotate in friction with the mounting body 1 or the cover 2, the rotating shaft 3 provides sufficient friction for hovering while having a simple structure, occupying little space, and having relatively high flexibility in structural movement.

[0055] In one specific embodiment, the mounting body 1 may be provided with two mounting seats 15A, which are arranged at an axial distance along the rotating shaft 3. Each mounting seat 15A has a first through hole 15, and the first through holes 15 on the two mounting seats 15A are coaxial. The cover body 2 includes a cover body 20 and a connecting body 21. The connecting body 21 has a connecting end located between the two mounting seats 15A, and the connecting end has a second through hole 201. The rotating shaft 3 is located inside the first through hole 15 and the second through holes 201 of the two mounting seats 15A.

[0056] In this embodiment, one of the first through hole 15 and the second through hole 201 is interference-fitted with the rotating shaft 3 for circumferential limiting, while the other rotates with friction against the rotating shaft 3. For example, the interference fit between the first through hole 15 and the rotating shaft 3 means that the diameter D2 of the first through hole 15 is smaller than the diameter D1 of the mating section of the rotating shaft 3. The size relationship between the two is sufficient to ensure that the rotating shaft 3 does not rotate relative to the mounting body 1 during the rotation of the cover 2. The diameter of the shaft segment of the rotating shaft 3 located inside the second through hole 201 is sufficient to provide enough frictional force for the cover 2 to suspend.

[0057] Of course, in the embodiment where the first through hole 15 rotates with friction against the rotating shaft 3, and the second through hole 201 is in an interference fit with the rotating shaft 3, the size relationship of each diameter is similar to that described above, and will not be described in detail here. The following text will take the interference fit between the first through hole 15 and the rotating shaft 3, and the friction fit between the second through hole 201 and the rotating shaft 3 as examples to continue to introduce the technical solution.

[0058] In this embodiment, the rotating shaft 3 can be inserted into the mounting body 1 and the cover 2 from one side of the first through hole 15, making installation convenient. The insertion of the rotating shaft 3 can be done with the aid of a tool or manually.

[0059] In one embodiment, the rotating shaft 3 is a hollow shaft, and its peripheral wall has an axially extending gap 31. The size of the gap 31 is adjustable under external force, thereby adjusting the diameter of the rotating shaft 3. That is, when an external force compresses the peripheral wall of the rotating shaft 3, the gap between the two side walls of the gap 31 decreases, and the diameter of the rotating shaft 3 decreases accordingly. This facilitates the insertion of the rotating shaft 3 into the first through hole 15 and the second through hole 201. When the external force on the rotating shaft 3 is removed, the two side walls of the gap 31 return to their original state, thus fulfilling the requirement for mating with the first through hole 15 and the second through hole 201.

[0060] In the above embodiment, the rotating shaft 3 can be manually assembled into the mounting body 1 and the cover 2, which is highly efficient.

[0061] In this embodiment, the mounting body 1 has a first surface 12, which can be the surface of the mounting body 1 facing the interior of the cabin. The first surface 12 has a recess 13, and an opening 11 is provided on the bottom wall 131 of the recess 13. The rotating shaft 3 is provided on the side of the mounting body 1 away from the first surface 12. That is, the rotating shaft 3 is located on the side of the mounting body 1 away from the cabin, so that the rotating shaft 3 can be shielded by the mounting body 1, thereby improving the appearance quality of the interior of the cabin.

[0062] In this embodiment, the recessed portion 13 also has a clearance channel 14. The cover 2 specifically includes a cover body 20 and a connecting body 21. The connecting body 21 is connected to the side of the cover body 20 facing the opening 11. The connecting body 21 includes a first connecting end 211 and a second connecting end 214. The first connecting end 211 passes through the clearance channel 14 and can be connected to the rotating shaft 3. Specifically, the first connecting end 211 is provided with a second through hole 201. The second connecting end 214 is connected to the cover body 20. The connecting body 21 and the cover body 20 can be an integrally formed structure. Of course, the connecting body 21 can also be relatively independent of the cover body 20 and fixedly connected to the cover body 20 by welding or bonding.

[0063] In this embodiment, when the cover 2 is in the state of blocking the opening 11, the cover body 20 is at least partially located in the recess 13. In one example, the surface of the cover body 20 facing away from the opening 11 can be flush with the first surface 12 of the mounting body 1. This makes the overall appearance of the power cover assembly relatively flat. Of course, the cover body 20 can be completely located inside the recess 13, or it can protrude partially from the recess 13.

[0064] In this embodiment, the connector 21 also has a protrusion 212, which is located between the first connecting end 211 and the second connecting end 214. The protrusion 212 extends along the axial direction of the rotating shaft 3. When the cover 2 is in the fully open opening 11 state, the protrusion 212 is in clearance fit with the bottom wall 131 of the recess 13, so that the passengers can hardly see the rear parts of the mounting plate from the outside, further improving the quality of the vehicle.

[0065] Without affecting the rotation of the cover 2, the gap between the protrusion 212 and the bottom wall 131 of the recess 13 should be as small as possible.

[0066] In one embodiment, the protrusion 212 has a groove 212A, the opening of which faces away from the rotating shaft 3, and the groove is located between the two end faces of the protrusion 212 along the axial direction of the rotating shaft 3. Thus, the groove 212A is located inside the protrusion 212, which prevents the protrusion 212 from shrinking, does not affect the appearance of the connector 21, and can reduce the overall weight.

[0067] In this embodiment, a bending section 16 is provided on the side of the clearance passage 14 away from the bottom wall 131. The bending section 16 bends toward the bottom wall 131. The bending section 16 can, to a certain extent, shield the components behind the mounting plate, thereby improving the quality of the vehicle.

[0068] In this embodiment, the connector 21 is hook-shaped, and the second connecting end 214 of the connector 21 is bent toward the cover body 20, with a gap between the second connecting end 214 and the cover body 20. The connector 21 with this structure occupies little space during installation.

[0069] In this embodiment, the second connecting end 214 of the connector 21 has a notch 213, the open portion of which faces the cover body 20. At least one end of the notch 213 along the axial direction of the rotating shaft 3 is a closed end. In this embodiment, the second connecting end 214 is configured with a notch 213 structure to prevent shrinkage and improve the injection molding quality of the cover body 20. On the other hand, it can reduce the overall weight of the cover body 2. Furthermore, to improve the aesthetic appearance of the cover body 2, the end face of the notch 213 facing the passenger along the axial direction of the rotating shaft 3 is preferably a closed end.

[0070] In this embodiment, a support wall 22 is also connected to the side of the cover body 20 facing the opening 11. When the cover body 2 is in the state of blocking the opening 11, the support wall 22 is located on the periphery of the opening 11, and the support wall 22 abuts against or has a predetermined gap with the bottom wall 131 of the recess 13. This can improve the stability of the cover body 20 when it is closed.

[0071] In this embodiment, the support wall 22 includes a frame body 221 and an elastic body 222. The frame body 221 and the cover body 20 can be made of the same material, such as rigid plastic. The frame body 221 and the cover body 20 can be integrally injection molded, or they can be made of metal. The elastic body 222 is at least disposed on the end face of the frame body 221 facing the bottom wall 131. The elastic body 222 abuts against or has a predetermined gap with the bottom wall 131 of the recess 13. The elastic body 222 can be made of a relatively soft material such as silicone or rubber. The elastic body 222 and the frame body 221 can be integrally molded using a two-color injection molding or two-stage injection molding process. In this embodiment, when the cover 2 rotates from the open position to the position of blocking the opening 11, even if the elastic body 222 collides with the bottom wall 131, the sound is relatively quiet.

[0072] In particular, when the cover 2 is in the state of blocking the opening 11, there is a predetermined gap S between the elastic body 222 and the bottom wall 131, which is about 0.5mm. This can prevent the cover body 20 from interfering with the bottom wall 131 after closing, causing it to open due to force, resulting in incomplete closure.

[0073] In one embodiment, the end face of the elastic body 222 away from the cover body 20 has a protrusion 2221. When the cover body 2 is in the state of blocking the opening 11, the protrusion 2221 contacts the bottom wall 131 of the recess 13. In this way, the contact area between the elastic body 222 and the bottom wall 131 is minimized, which can be multi-point contact, further reducing the probability of the cover body 20 being unable to close properly due to interference with the bottom wall 131 after closing.

[0074] The vehicle in this embodiment has the aforementioned power cover assembly, and therefore the vehicle also has the aforementioned technical effects of the power cover assembly.

[0075] For other aspects of the vehicle's structure, please refer to current technology; this application will not elaborate further.
