DETAILED DESCRIPTION

[0033] In order to make the ordinary person skilled in the art better understand the technical solutions of the present application, the technical solutions in the embodiments of the present application will be described clearly and completely below in conjunction with the drawings.

[0034] It should be noted that the terms "first", "second", etc. in the specification and claims of the present application and the above drawings are used to distinguish similar objects, and do not necessarily describe a specific order or sequence. It should be understood that the data thus used can be interchanged under appropriate circumstances, so that the embodiments of the present application described herein can be implemented in an order other than that illustrated or described herein. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present application. Rather, they are merely examples of devices and methods consistent with some aspects of the present application, as detailed in the appended claims.

[0035] This application provides a vehicle. The specific type of vehicle is not specifically limited in this application; for example, the vehicle provided in this application can be an electric vehicle, a hybrid electric vehicle, or a solar-powered vehicle. Furthermore, the vehicle provided in this application can also be of different forms. For example, the vehicle provided in this application can be a sedan, a sport utility vehicle (SUV), or a multi-purpose vehicle (MPV).

[0036] The vehicle may include a frame. The frame may form the overall shape of the vehicle's exterior and create a passenger seating space. The frame may include door structures through which users can enter and exit.

[0037] Furthermore, to enable vehicle propulsion, the vehicle may also include an electric drive system assembly. The electric drive system assembly may include an electric drive system. This electric drive system may include a drive motor and a reducer. The drive motor provides power, and the reducer can be connected to the drive motor. The reducer can regulate the speed, allowing the vehicle to operate at different speeds. Depending on the driving method, the electric drive system can be configured as front-wheel drive, rear-wheel drive, or four-wheel drive.

[0038] In addition, the vehicle may include a transmission system that can be connected to an electric drive system to transmit power generated by the engine to the wheels.

[0039] To supply power to electrical components such as the drive motor, the vehicle provided in this application embodiment also includes a battery system. The battery system may include a battery pack, which can be used to provide electrical energy. The battery pack can be connected to the vehicle's electric drive system and other electrical components. In this way, the electrical energy from the battery pack can be transferred to various components of the vehicle for power supply.

[0040] In addition, the vehicle provided in this application embodiment may also include a sun visor, which flips up and down to shield the driver and passengers from the sun.

[0041] like Figure 1 As shown, this application provides a sun visor 100, which mainly includes a sun visor body 1 and a retaining spring 2 connected to the sun visor body 1.

[0042] The sun visor 100 also includes a pivot 3, one end of which is inserted into a retaining spring 2 and rotates in cooperation with the retaining spring 2. Because the pivot 3 rotates in cooperation with the retaining spring 2, the driver or passenger can hold the sun visor body 1 and flip the sun visor body 1 up and down. During this process, the retaining spring 2 can rotate relative to the pivot 3 around the axis of the pivot 3, thereby realizing the flipping of the sun visor body 1.

[0043] It should be noted that, in general, the other end of the rotating shaft 3 is connected with a fixing seat, so as to provide fixed support for the rotating shaft 3 and the sun visor body 1, wherein the other end of the rotating shaft 3 refers to the end not in rotational cooperation with the snap spring 2.

[0044] In order to solve the problem that friction exists between the rotating shaft 3 and the snap spring 2, causing noise when the rotating shaft 3 and the snap spring 2 relatively rotate, as shown in Figure 2 The rotating shaft 3 provided by the present application is provided with a plurality of oil storage grooves 30 on the cooperation surface 3000 of the rotating shaft 3 and the snap spring 2, and the plurality of oil storage grooves 30 are arranged at intervals along the axial direction of the rotating shaft 3.

[0045] For example, the plurality of oil storage grooves 30 can be arranged at equal intervals along the axial direction of the rotating shaft 3, so that when the rotating shaft 3 and the snap spring 2 relatively rotate, the lubricant stored in the plurality of oil storage grooves 30 arranged at intervals can be evenly applied to the contact surface of the rotating shaft 3 and the snap spring 2, solving the problem of uneven application of lubricant between the rotating shaft 3 and the snap spring 2, and thus solving the problem of noise caused by dry friction between the rotating shaft 3 and the snap spring 2.

[0046] As shown in Figure 2 In some embodiments of the present application, the oil storage groove 30 extends along the rotation direction X of the rotating shaft 3.

[0047] The extension direction of the oil storage groove 30 extends along the rotation direction of the rotating shaft 3, or in other words, the extension direction of the oil storage groove 30 is parallel to the rotation direction of the rotating shaft 3. This arrangement can reduce the friction between the snap spring 2 and the oil storage groove 30, and avoid jamming during the rotation of the sun visor body.

[0048] In addition, as shown in Figure 1 The sun visor body 1 is also formed with a guide portion 10, the guide portion 10 is formed with a guide hole (not shown in the figure), and the guide hole is in communication with the inside of the snap spring 2. In this way, when the rotating shaft 3 is inserted into the inside of the snap spring 2, the rotating shaft 3 can be aligned with the guide hole of the guide portion 10 and then inserted into the inside of the snap spring 2. On the one hand, the guide portion 10 can play a certain guiding role, reducing the difficulty of inserting the rotating shaft 3 into the inside of the snap spring 2, and on the other hand, the rotating shaft 3 and the sun visor body 1 are rotatably connected through the guide portion 10, increasing the connection points between the rotating shaft 3 and the sun visor body 1, so that the sun visor body 1 is more stable during the process of turning up and down.

[0049] As shown in Figure 3 In some embodiments of the present application, the rotating shaft 3 provided by the present application comprises a rotating shaft body 31 and a cover layer 32. The cover layer 32 is arranged on the outer circumferential surface of the rotating shaft body 31, and the oil storage groove 30 is arranged on the cover layer 32.

[0050] In some embodiments, the rotating shaft body 31 described above can be made of a metal material to ensure that the rotating shaft 3 has good rigidity sufficient to support the sun visor body 1. For example, the rotating shaft body 31 can be made of stainless steel. Based on this, the covering layer 32 arranged on the outer circumferential surface of the rotating shaft body 31 can be made of a plastic material, for example, can be made of polyoxymethylene (POM) or polyamide 6 (PA6), both of which are plastic materials with good wear resistance and mechanical properties. It should be noted that the covering layer 32 can also be made of other materials with good wear resistance and mechanical properties.

[0051] In addition, it can be understood that the hardness of the covering layer 32 made of a plastic material is generally less than the hardness of the rotating shaft body 31 made of metal, and the plastic material has better plasticity. Therefore, the oil storage groove 30 is formed on the covering layer 32 made of a plastic material, which has lower processing difficulty compared to forming the oil storage groove 30 directly on the rotating shaft body 31 made of metal, and the processing precision of the oil storage groove 30 can be guaranteed.

[0052] In some embodiments of the present application, the width W of the oil storage groove 30 satisfies: 1.0 mm≤W≤2.0 mm. It can be understood that when the width W of the oil storage groove 30 is less than 1.0 mm, the width of the oil storage groove 30 is too small, and the oil storage groove 30 cannot store enough lubricant, thereby causing the rotating shaft 3 and the snap spring 2 to be insufficiently lubricated. When the width W of the oil storage groove 30 is greater than 2.0 mm, the size of a single oil storage groove 30 is too large. The number of oil storage grooves 30 arranged in the limited range of the cooperation surface 3000 of the rotating shaft 3 and the snap spring 2 is small, and cannot be uniformly arranged in the cooperation surface 3000, so that the lubricant cannot be uniformly applied to the rotating shaft 3 and the snap spring 2.

[0053] On this basis, the depth D1 of the oil storage groove 30 satisfies: D1≥0.5 mm. When the depth D1 of the oil storage groove 30 is less than 0.5 mm, the depth of the oil storage groove 30 is too small, which will cause the oil storage groove 30 to be unable to store enough lubricant, thereby causing the rotating shaft 3 and the snap spring 2 to be insufficiently lubricated. Therefore, the depth D1 of the oil storage groove 30 can be 0.5 mm, 0.6 mm, or 0.7 mm, to ensure that the oil storage groove 30 can store enough lubricant, thereby ensuring that the rotating shaft 3 and the snap spring 2 can be uniformly coated with lubricant.

[0054] In some embodiments of the present application, the distance L between the two adjacent oil reservoirs 30 satisfies: 3mm≤L≤7mm. When the distance L between the two adjacent oil reservoirs 30 is less than 3mm, the distance between the two adjacent oil reservoirs 30 is too small, which increases the processing difficulty of the oil reservoir 30. When the distance L between the two adjacent oil reservoirs 30 is greater than 7mm, the distance between the two adjacent oil reservoirs 30 is too large, which may cause an area without lubricant between the two adjacent oil reservoirs 30, and further causes dry friction between the shaft 3 and the clamp spring 2, resulting in noise. Therefore, the distance L between the two adjacent oil reservoirs 30 can be 4mm, 5mm or 6mm, etc., to ensure that the lubricant can be evenly applied to the surface of the shaft 3 and the clamp spring 2 without increasing the processing difficulty of the oil reservoir 30.

[0055] In some embodiments of the present application, as shown in Figure 2 The plurality of oil reservoirs 30 includes a first oil reservoir 301 and a second oil reservoir 302, the first oil reservoir 301 and the second oil reservoir 302 are arranged along the axial direction of the shaft 3, and the first oil reservoir 301 and the second oil reservoir 302 are arranged opposite to each other along the radial direction of the shaft 3.

[0056] For ease of understanding, the shaft 3 can be divided into an upper half shaft 3001 and a lower half shaft 3002, and the upper half shaft 3001 and the lower half shaft 3002 constitute a complete shaft 3. Therefore, the first oil reservoir 301 and the second oil reservoir 302 are arranged opposite to each other along the radial direction of the shaft 3, which can be understood as that the first oil reservoir 301 is arranged on the upper half shaft 3001 of the shaft 3, and the second oil reservoir 302 is arranged on the lower half shaft 3002 of the shaft 3. Alternatively, the first oil reservoir 301 is arranged on the lower half shaft 3002 of the shaft 3, and the second oil reservoir 302 is arranged on the upper half shaft 3001 of the shaft 3.

[0057] In this way, the first oil reservoir 301 and the second oil reservoir 302 are arranged opposite to each other along the radial direction of the shaft 3, which can make the oil reservoir 30 better distributed on the cooperation surface 3000 of the shaft 3 and the clamp spring 2, thereby playing a better lubricating effect.

[0058] Continuing to refer to Figure 2 , the first oil reservoir 301 and the second oil reservoir 302 are arranged alternately along the axial direction of the shaft 3.

[0059] In this way, on the basis of the first oil reservoir 301 and the second oil reservoir 302 being arranged opposite to each other along the radial direction of the shaft 3, the first oil reservoir 301 and the second oil reservoir 302 are arranged alternately along the axial direction of the shaft 3, which can further improve the uniformity of the arrangement of the oil reservoir 30, thereby further ensuring that the lubricant can be more evenly applied to the surface of the shaft 3 and the clamp spring 2.

[0060] As shown in the drawings, in some embodiments of the present application, the wave structure 4 is arranged on the matching surface 3000 of the shaft 3 and the snap spring 2, and the wave structure 4 includes a plurality of wave crests 41 and a plurality of wave troughs 42 formed between adjacent wave crests 41. Figure 4

[0061] In this way, the wave troughs 42 of the wave structure 4 can further store lubricant, increase the storage capacity, and the wave structure 4 can be uniformly arranged in the matching surface, which can further improve the uniformity of the lubricant distribution. Further, the dry friction phenomenon between the shaft 3 and the snap spring 2 can be avoided.

[0062] The depth of the wave trough 42 is D2, and the depth D2 of the wave trough satisfies: 80 μm≤D2≤120 μm. When the depth D2 of the wave trough 42 is less than 80 μm, the wave trough 42 cannot effectively store lubricant. When the depth D2 of the wave trough 42 is greater than 120 μm, the length of the wave crest 42 can be too long, and as the shaft 3 and the snap spring 2 rotate relative to each other, the wave crest 41 can be squeezed into the wave trough 42, which on the one hand reduces the storage capacity, and on the other hand, the wave crest 41 generates a reaction force, which increases the resistance between the shaft 3 and the snap spring 2, which is not conducive to the turning of the sun visor body 1.

[0063] The above is only a specific embodiment of the present application, but the protection scope of the present application is not limited thereto. Any change or replacement within the technical scope disclosed in the present application should be covered in the protection scope of the present application. Therefore, the protection scope of the present application should be subject to the protection scope of the claims.​
