Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of automobiles, in particular to a damping piece, a turnover mechanism, a display device and a vehicle. BACKGROUND

[0002] Due to the unevenness of the ground, the automobile will vibrate during driving, and the vibration will be transmitted to the vehicle, affecting the use of some equipment in the vehicle. For example, a display device in the vehicle which can be turned over. The display device includes a display screen, a support, an output shaft on which the display screen is rotatably installed, and a gear set for transmitting power of a motor to the output shaft. Since the gear set transmits power through gear meshing, there is a gap between the meshing teeth. When the gear set is subjected to vibration, relative rotation between the gears will occur, causing the output shaft to rotate, causing the display screen to shake, which is not conducive to the user using the display device.

[0003] In related technologies, in order to reduce the influence of vehicle vibration on such a turnable device, a damping piece is configured on the output shaft of the device to increase the damping between the support and the output shaft. In this way, when the gear set is subjected to vibration, the damping force between the output shaft and the support can be increased by the damping piece to prevent the output shaft from rotating, thereby improving the positional stability of the output shaft to ensure the position of the display screen.

[0004] In related technologies, since the display screen and other such devices need to be turned over when in use, one annular surface of the damping piece is a fixed annular surface that needs to be fixed relative to one of the output shaft and the support, and the other annular surface is a rotating annular surface that rotates relative to the other. In related technologies, in order to improve the smoothness of the rotation of the damping piece, an oil storage groove is provided on the rotating annular surface of the damping. However, the sealing performance of the oil storage groove in related technologies is poor, and the lubricating oil is easily squeezed out of the rotating annular surface, causing the lubricating oil to flow out, thereby reducing the lubricating effect or even causing lubrication failure.

[0039] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the present application.

[0040] The following will be described with reference to the drawings in the embodiments of the present application. Figures 1 to 6 A damper 1, a turnover mechanism 2, a display device and a vehicle provided by the embodiments of the present application will be described.

[0041] Please refer to Figure 1 and Figure 2 , or Figure 3 and Figure 4 , Figure 1 is a structural schematic view of a damper 1 provided in the example embodiment of the present disclosure, Figure 2 is Figure 1 is a sectional view of A-A in Figure 3 is a structural schematic view of another damper 1 provided in the example embodiment of the present disclosure, Figure 4 is Figure 3Figure 2 is a sectional view of B-B. Embodiments of the present application provide a damping member 1. The damping member 1 is annular structure, and the damping member 1 has a first annular surface 11 for interference fit. The damping member 1 is provided with an oil storage groove 13 on the first annular surface 11.

[0042] The material of the damping member 1 includes but is not limited to plastic material and metal material.

[0043] It can be understood that the first annular surface 11 is the inner annular surface or the outer annular surface of the damping member 1.

[0044] It can be understood that the first annular surface 11 is the part of the damping member 1 that interferes with the part of the flipping mechanism 2 that contacts the damping member 1. The flipping mechanism 2 includes a housing 21, an output shaft 24 rotatably arranged in the housing 21 and connected to a part that needs to be flipped, such as a display screen, at one end, and a motor 22 that drives the output shaft 24 to rotate. When the first annular surface 11 is the outer annular surface, it interferes with the inner wall of the housing 21. When the first annular surface 11 is the inner annular surface, it interferes with the output shaft 24.

[0045] It can be understood that when the first annular surface 11 is the outer annular surface of the damping member 1, the structure of the damping member 1 can be as shown in Figure 1 and Figure 2 Correspondingly, when the damping member 1 is applied to the flipping mechanism 2, the damping member 1 is sleeved on the output shaft 24, and the inner annular surface of the damping member 1 is circumferentially blocked with the output shaft 24, so that the damping member 1 rotates synchronously with the output shaft 24. At this time, the first annular surface 11 of the damping member 1 interferes with the inner wall of the housing 21, so that when the gear set 23 vibrates and the output shaft 24 has a tendency to rotate, a larger damping force can be formed between the damping member 1 and the housing 21 to hinder the rotation of the output shaft 24. In this way, the position stability of the device using the flipping mechanism 2, such as a display screen, can be improved. The blocking cooperation between the damping member 1 and the output shaft 24 can be achieved in various structures, for example, one of the damping member 1 and the output shaft 24 is provided with a slot, and the other is provided with a plug, and the plug is inserted into the slot in the radial direction. Alternatively, the part of the output shaft 24 that cooperates with the damping member 1 is a flat shaft structure, and the shape of the cross section of the first annular surface 11 is consistent with the shape of the cross section of the flat shaft structure.

[0046] It can be understood that when the first annular surface 11 is the inner annular surface of the damping member 1, the structure of the damping member 1 can be as shown in Figure 3 and Figure 4Correspondingly, when the damping member 1 is applied to the turnover mechanism 2, the damping member 1 is sleeved on the output rotating shaft 24, and the outer ring surface of the damping member 1 is in circumferential stop cooperation with the inner wall of the shell 21, so that the damping member 1 is fixed relative to the shell 21. At this time, the first ring surface 11 of the damping member 1 is in interference cooperation with the output rotating shaft 24, so that when the gear set 23 vibrates and the output rotating shaft 24 has a rotating tendency, a larger damping force can be formed through the interference cooperation between the damping member 1 and the output rotating shaft 24 to hinder the rotation of the output rotating shaft 24. In this way, the position stability of the equipment such as the display screen using the turnover mechanism 2 can be improved. The stop cooperation between the damping member 1 and the shell 21 can be realized in various structures, for example, one of the damping member 1 and the shell 21 is provided with a slot, and the other is provided with a plug, and the plug is inserted into the slot in the radial direction. Alternatively, the cross section of the part on the shell 21 cooperating with the damping member 1 is non-circular, and the cross section of the first ring surface 11 is consistent with the cross section of the part on the shell 21 cooperating with it.

[0047] In the embodiment, by providing the oil storage groove 13 on the first ring surface 11 of the damping member 1, the lubricating oil in the oil storage groove 13 can be enclosed by the groove side wall of the oil storage groove 13, and when the damping member 1 is applied to the turnover mechanism 2, the slot of the oil storage groove 13 can be covered to be closed based on the interference cooperation between the first ring surface 11 and the corresponding part. In this way, the leakage of the lubricating oil can be effectively avoided, so that the lubricating oil in the oil storage groove 13 can continuously lubricate the damping member 1 and the part in interference cooperation with it, so as to ensure the lubricating effect of the damping member 1 and prolong the service life of the damping member 1.

[0048] Please refer to Figure 1 or Figure 3 In some embodiments, the oil storage groove 13 is arranged in the axial direction of the damping member 1. In this way, the size of the oil storage can be increased to store more lubricating oil, so as to increase the lubricating area of the damping member 1 to improve the lubricating effect of the damping member 1.

[0049] Please refer to Figure 1 or Figure 3 In some embodiments, the oil storage groove 13 is arranged in the axial direction of the damping member 1. In this way, the size of the oil storage can be increased to store more lubricating oil, so as to increase the lubricating area of the damping member 1 to improve the lubricating effect of the damping member 1.

[0050] Specifically, the plurality of oil storage grooves 13 are uniformly arranged in the circumferential direction of the damping member 1.

[0051] Specifically, the oil storage groove 13 has N number, the center angle between two adjacent oil storage grooves 13 in the circumferential direction is α = 360° / N. The central angle of each oil storage groove 13 is β, which satisfies: 0.4α≤β≤0.7α. In this way, each oil storage groove 13 can have a larger oil storage area, and the strength of the first annular surface of the damping member 1 can be ensured, so as to facilitate the interference fit between the damping member 1 and the corresponding component, thereby facilitating the damping force applied by the damping member 1 to the output rotating shaft 24.

[0052] Referring to Figure 2 or Figure 4 In some embodiments, the bottom wall of the oil storage groove 13 is an arc-shaped concave surface. The center of the arc-shaped concave surface is located on the side of the oil storage groove 13 away from the bottom wall of the oil storage groove 13. In this way, the stress concentration of the damping member 1 at the groove can be reduced, and the stress state of the damping member 1 can be improved, thereby improving the stability of the damping member 1.

[0053] It can be understood that when the first annular surface 11 is the outer annular surface of the damping member 1, the center of the arc-shaped concave surface is located on the side of the bottom wall of the oil storage groove 13 away from the axis, as shown in Figure 2 For example, the center of the arc-shaped concave surface can be arranged on the circumferential line where the first annular surface 11 is located.

[0054] It can be understood that when the first annular surface 11 is the inner annular surface of the damping member 1, the center of the arc-shaped concave surface is located on the side of the bottom wall of the oil storage groove 13 close to the axis, as shown in Figure 4 For example, the center of the arc-shaped concave surface can be arranged on the circumferential line where the first annular surface 11 is located.

[0055] In some embodiments, the damping member 1 is a plastic member.

[0056] Specifically, the material of the damping member 1 can be a thermoplastic polyurethane material, an ultrahigh molecular weight polyethylene material, etc.

[0057] In the present embodiment, by setting the damping member 1 as a plastic member, on the one hand, a more stable damping force can be provided, and on the other hand, the damping member 1 can absorb small vibrations based on the elasticity of the plastic member, so as to reduce the noise generated by the vibration and reduce the material wear.

[0058] Referring to Figure 1 and Figure 2 In some embodiments, the first annular surface 11 is the outer annular surface of the damping member 1.

[0059] It can be understood that when the damping member 1 is a plastic member, it is formed by injection molding. If the first annular surface 11 is set as the inner annular surface, since the mold for forming the oil storage groove 13 needs to be withdrawn from the inner annular surface of the damping member 1, the demolding difficulty will be increased, thereby increasing the design difficulty of the mold.

[0060] Based on this, in the embodiment, by setting the first annular surface 11 as an outer annular surface, the difficulty of setting the mold for injection molding the damping member 1 can be reduced, thereby reducing the difficulty of demolding the damping member 1, so as to facilitate improving the molding efficiency of the damping member 1.

[0061] Please refer to Figure 2 In some embodiments, along the circumferential direction of the damping member 1, the damping member 1 has a first section 18 and a second section 19 connected in sequence, the thickness D of the first section 18 is greater than that of the second section 19, and the first section 18 is provided with the through groove 14. The through groove 14 is arranged along the axial direction of the damping member 1. In this way, by arranging the through groove 14 at the part of the damping member 1 with the maximum interval D, the local shrinkage of the damping member 1 caused by the local over-thickness of the plastic material can be effectively avoided, so as to ensure the structural size of the damping member 1, facilitate improving the consistency of the damping force provided by the damping member 1, and thus improve the stability and reliability of the damping force provided by the damping member 1.

[0062] It can be understood that the interval between the first annular surface 11 and the second annular surface 12 is D. The interval D between the first annular surface 11 and the second annular surface 12 is not uniform. The through groove 14 is arranged at the part of the second annular surface 12 with the maximum interval D.

[0063] Please refer to Figure 2 In some embodiments, the damping member 1 also has a second annular surface 12. One of the first annular surface 11 and the second annular surface 12 is the inner annular surface of the damping member 1, and the other is the outer annular surface of the damping member 1. The through groove 14 is arranged on the second annular surface 12. In this way, the oil storage groove 13 and the through groove 14 can be arranged on different annular surfaces of the damping member 1 respectively, so as to reduce the layout difficulty of the oil storage groove 13 and the through groove 14, and avoid their interference.

[0064] Please refer to Figure 2 In some embodiments, the second annular surface 12 is the inner annular surface of the damping member 1. The part of the second annular surface 12 corresponding to the first section 18 is a plane 121. The through groove 14 is arranged on the plane 121 of the second annular surface 12. In this way, the damping member 1 has a regular structure, so as to facilitate reducing the manufacturing difficulty of the damping member 1.

[0065] In addition, by setting the second annular surface 12 as the inner annular surface of the damping member 1, correspondingly, the first annular surface 11 is the outer annular surface of the damping member 1, so as to increase the arrangeable circumference of the oil storage groove 13, facilitate improving the lubricating area of the damping member 1, and thus improve the lubricating effect of the damping member 1.

[0066] In this embodiment, the shape of the cross section of the second annular surface 12 is rectangular, correspondingly, the second annular surface 12 has four planes 121. The through groove 14 is arranged on each plane 121.

[0067] Please refer toFigure 2 In some embodiments, the portion of the second annular surface 12 corresponding to the second section 19 is an arc-shaped concave surface, and the arc-shaped concave surface is smoothly connected to the flat surface adjacent thereto, i.e., a fillet is arranged at the corner of the second annular surface 12. In this way, the stress concentration of the damping member 1 at the corner can be reduced, so as to improve the stress state of the damping member 1, thereby improving the stability of the damping member 1.

[0068] Specifically, the fillet is tangentially connected to the flat surface 121 connected to the second annular surface 12.

[0069] In some embodiments, the damping member 1 is a metal member. In this way, the damping member 1 can have a higher hardness, so as to improve the pressure capacity and deformation resistance of the damping member 1. In addition, when the temperature of the working environment of the damping member 1 changes greatly, the size of the damping member 1 changes less, thereby facilitating the stable provision of damping force with good consistency.

[0070] Referring to Figure 3 or Figure 4 In some embodiments, the first annular surface 11 is an inner annular surface of the damping member 1. In this way, the outer annular surface of the damping member 1 is stop-fitted with the inner wall of the housing 21, and the output shaft 24 does not need to be machined with a structure for stop-fitting with the damping member 1 in the circumferential direction, so as to ensure the integrity of the output shaft 24 cooperating with the first annular surface 11, thereby improving the strength of the output shaft 24.

[0071] Referring to Figure 3 or Figure 4 In some embodiments, the damping member 1 is provided with an opening 15. The opening 15 penetrates both ends of the damping member 1 in the axial direction of the damping member 1, and penetrates one side of the damping member 1 in the radial direction of the damping member 1. In this way, the damping member 1 can be formed by punching the metal sheet to form the oil storage groove 13 and then being rolled, so as to reduce the manufacturing cost of the damping member 1.

[0072] Referring to Figure 3 or Figure 4 In some embodiments, the damping member 1 further has a second annular surface 12. One of the first annular surface 11 and the second annular surface 12 is an inner annular surface of the damping member 1, and the other is an outer annular surface of the damping member 1. The second annular surface 12 is provided with a convex 16.

[0073] It can be understood that when the second annular surface 12 is an outer annular surface, the convex 16 can be inserted into the groove on the housing 21, so that the damping member 1 is stop-fitted with the housing 21 in the circumferential direction, thereby fixing the damping member 1 relative to the housing 21. In another embodiment, the damping member 1 is applied to the turnover mechanism 2, and the damping member 1 can be in an elastically compressed state, for example, the convex 16 is in an elastically compressed state. In this way, the elastic force of the damping member 1 can be applied to the output shaft 24, so that the output shaft 24 is continuously subjected to damping force.

[0074] It can be understood that when the second annular surface 12 is an inner annular surface, the convex bump 16 is inserted into the groove on the rotating shaft, so that the damping member 1 is in circumferential stop cooperation with the rotating shaft, thereby fixing the damping member 1 relative to the rotating shaft.

[0075] In the embodiment, through the above arrangement, the structure strength of the damping member 1 can be enhanced by the convex bump 16, so as to improve the reliability of the damping member 1, and the structure for stop cooperation between the damping member 1 and the output rotating shaft 24 or the housing 21 is simple and easy to manufacture.

[0076] Please refer to Figure 3 or Figure 4 In some embodiments, the convex bump 16 is arranged opposite to the oil storage groove 13 along the radial direction of the damping member 1. In this way, the oil storage groove 13 and the convex bump 16 can be formed on both sides of the metal sheet through one-time stamping of the metal sheet, thereby improving the manufacturing efficiency of the damping member 1.

[0077] In some embodiments, the first annular surface 11 is provided with a lubricating layer 17. In this way, the self-lubricating effect can be achieved by arranging the lubricating layer 17 on the first annular surface 11.

[0078] For example, the lubricating layer 17 is at least one of the following lubricating layers 17: Teflon coating, molybdenum disulfide coating, graphene coating, DLC coating, polytetrahydrofuran coating, and silicone coating.

[0079] The lubricating layer 17 can be coated on the first annular surface 11 or plated on the first annular surface 11.

[0080] Please refer to Figure 5 and Figure 6 , Figure 5 is a structural schematic view of the turnover mechanism 2 provided in the exemplary embodiments of the present disclosure, Figure 6 is an exploded view of the turnover mechanism 2 provided in the exemplary embodiments of the present disclosure. Accordingly, the embodiments of the present application also provide a turnover mechanism 2. The turnover mechanism 2 comprises a housing 21, a motor 22, a gear set 23, an output rotating shaft 24, a mounting bracket 25, and the damping member 1 provided by some embodiments of the present application. The housing 21 has a mounting cavity. The motor 22 is arranged in the mounting cavity. The gear set 23 is arranged in the mounting cavity. The input end of the gear set 23 is connected with the output shaft of the motor 22. The output rotating shaft 24 is arranged in the mounting cavity. One end of the output rotating shaft 24 is connected with the output end of the gear set 23, and the other end of the output rotating shaft 24 penetrates out of the housing 21. The mounting bracket 25 is connected with the other end of the output rotating shaft 24. The damping member 1 is sleeved on the output rotating shaft 24. One of the inner wall of the housing 21 and the output rotating shaft 24 is in interference fit with the first annular surface 11, and the other is in stop cooperation with the damping member 1 along the circumferential direction of the damping member 1.

[0081] It can be understood that the shell 21 comprises a gear bracket 211 and a cover plate 212, which are mutually overlapped to define a mounting cavity.

[0082] In addition, the turnover mechanism 2 can further comprise a damping rubber sleeve 26 and a clutch sleeve 27. A plurality of bolt through holes are provided on the shell 21, and a damping rubber sleeve 26 is arranged at one end of each bolt through hole. The rod end of the bolt passes through the bolt through hole and the damping rubber sleeve 26 and is connected with the vehicle frame. In this way, the damping rubber sleeve can be used for damping.

[0083] The clutch sleeve 27 is sleeved with the end of the output shaft 24 close to the mounting bracket 25. The mounting bracket 25 is provided with a mounting hole, and the clutch sleeve 27 is located in the mounting hole and is in circumferential stop cooperation with the mounting bracket 25. In this way, the clutch sleeve 27 can transmit the rotating power of the output shaft 24 to the mounting bracket 25 to drive the mounting bracket 25 to rotate synchronously.

[0084] In the embodiment, by using the damping member 1 provided by some embodiments of the present application, the lubricating oil in the oil storage groove 13 is enclosed by the groove side wall of the oil storage groove 13, so that when the damping member 1 is applied to the turnover mechanism 2, the slot of the oil storage groove 13 can be covered based on the interference fit between the first annular surface 11 and the corresponding component, so as to close the oil storage groove 13. In this way, the leakage of lubricating oil can be effectively avoided, so that the lubricating oil in the oil storage groove 13 can continuously lubricate the damping member 1 and the component in interference fit with it, so as to ensure the lubricating effect of the damping member 1 and prolong the service life of the damping member 1. Finally, the reliability of the turnover mechanism 2 can be improved.

[0085] Correspondingly, the embodiments of the present application also provide a display device. The display device comprises a display screen and the aforementioned turnover mechanism 2. The shell 21 of the display screen is connected with the mounting bracket 25.

[0086] It can be understood that the mounting bracket 25 is located at the back of the display screen.

[0087] In the embodiment, by using the turnover mechanism 2 provided by some embodiments of the present application, the lubricating oil in the oil storage groove 13 is enclosed by the groove side wall of the oil storage groove 13, so that when the damping member 1 is applied to the turnover mechanism 2, the slot of the oil storage groove 13 can be covered based on the interference fit between the first annular surface 11 and the corresponding component, so as to close the oil storage groove 13. In this way, the leakage of lubricating oil can be effectively avoided, so that the lubricating oil in the oil storage groove 13 can continuously lubricate the damping member 1 and the component in interference fit with it, so as to ensure the lubricating effect of the damping member 1 and prolong the service life of the damping member 1. Finally, the reliability of the display device can be improved.
