Description

Technical Field

[0001] This application relates to the field of automobile manufacturing, and in particular to a damping component, a transmission component, an in-vehicle display terminal, and a vehicle. Background Technology

[0002] With the increasing demands for entertainment and intelligence in modern automobiles, and the growing popularity of mobile devices, the functions and forms of in-vehicle multimedia are becoming increasingly diverse. Multifunctional, large-size in-vehicle display terminals that can connect to mobile phones, computers, or the internet have become the mainstream trend for future development. To enhance in-vehicle storage, existing in-vehicle display terminals often have storage boxes at the bottom. The display terminal is connected to a transmission device, which drives the display terminal to open or close the storage box.

[0003] The existing transmission system includes manual and automatic drive modes. Under normal power conditions, the automatic drive mode is used to rotate the vehicle display terminal. When maintenance is required or the vehicle is in a power-off state during assembly, the manual drive mode is used to rotate the display terminal. In manual drive mode, the transmission system uses damping to slowly raise or lower the display terminal, but this damping also operates in automatic drive mode. Furthermore, the transmission system operates far more frequently in automatic drive mode than in manual drive mode. Therefore, having the damping operate in both manual and automatic drive modes significantly reduces its lifespan, making it prone to damage. Summary of the Invention

[0004] This application primarily addresses the technical problem of shortened service life caused by the use of damping in existing transmission devices in both automatic and manual drive modes. It provides a damping unit that is used in the first drive mode but not in the second drive mode, a damping component, a transmission device, an in-vehicle display terminal, and a vehicle.

[0005] To address the aforementioned technical problems, this application provides a damping component in its first aspect, characterized in that it is used for transmission connection with a first transmission portion of a transmission component, the damping component comprising...

[0006] A damping unit is rotatable about a first rotation axis, which is arranged along a first direction. The damping unit includes a damping shell and a damping core. The damping core is located inside the damping shell, and the damping core interacts with the damping shell to slow down the rotation speed of the damping core.

[0007] A moving unit is provided to drive a damping unit to move along the first direction, to approach or move away from the first transmission point of the transmission assembly. Under the movement of the damping unit, the interaction between the damping unit and the transmission assembly includes a first driving mode and a second driving mode.

[0008] In the first driving mode, the damping unit is connected to the first transmission point of the transmission assembly, and the transmission assembly rotates synchronously with the damping unit;

[0009] In the second driving mode, the damping unit is separated from the first transmission part of the transmission assembly, and the transmission assembly rotates independently.

[0010] In one embodiment, the moving unit includes a first moving structure and a second moving structure, the first moving structure and the second moving structure being located at opposite ends of the damping unit along the first direction, the first moving structure being used to drive the damping unit to move toward the first transmission point of the transmission assembly, and the second moving structure being used to drive the damping unit to move away from the first transmission point of the transmission assembly.

[0011] In one possible implementation, the damping component further includes,

[0012] The limiting unit includes a first limiting structure and a second limiting structure. A plurality of the first limiting structures are arranged circumferentially on the outer surface of the damping shell. The second limiting structure is located on one side of the damping shell along a second direction. The first limiting structure and the second limiting structure interact with each other to ensure that the damping shell rotates unidirectionally around the first rotation axis.

[0013] In one embodiment, the rotation direction of the damping core includes forward rotation about the first rotation axis and reverse rotation about the first rotation axis, wherein the forward rotation and the reverse rotation are opposite in direction.

[0014] The first limiting structure is a first limiting protrusion disposed on the surface of the damping shell. A first limiting groove is disposed through the first limiting protrusion along the first direction. The first limiting groove includes two corresponding first side and second side. The direction from the first side to the second side is positive, and the direction from the second side to the first side is negative.

[0015] The second limiting structure includes a second limiting protrusion and a first elastic member. The first elastic member is connected to the second limiting protrusion to drive the second limiting protrusion to abut against the outer surface of the damping housing or the first limiting protrusion.

[0016] When the damping core rotates in the positive direction around the first rotation axis, the second limiting protrusion floats upward after it abuts against the first limiting surface. The second limiting protrusion disengages from the first limiting groove in the first limiting protrusion, and the damping shell rotates synchronously with the damping core.

[0017] When the damping core rotates in the opposite direction around the first rotation axis, the second limiting protrusion abuts against the second limiting surface, and the damping shell remains stationary, while the damping core rotates independently within the damping shell.

[0018] A second aspect of this application provides a transmission device, characterized in that it includes the damping component described in Embodiment 2, and further includes a transmission component, the transmission component comprising...

The first movable structure is used to drive the movable component away from the rotating component, and the second driving component is used to drive the movable component closer to the rotating component.

[0022] The first limiting member includes a third limiting structure and a fifth limiting structure. The third limiting structure is disposed on the rotating member, and the fifth limiting structure is disposed on the moving member.

[0023] When the moving member moves away from the rotating member under the drive of the first moving structure, the fifth limiting structure is misaligned with the third limiting structure under the drive of the third driving member, and the damping unit moves towards the first transmission point of the transmission assembly to form the first driving mode of the transmission device; when the fifth limiting structure is correspondingly set with the third limiting structure under the drive of the rotating shaft, the moving member moves closer to the rotating member under the drive of the second driving member, and the damping unit moves away from the first transmission point of the transmission assembly to form the second driving mode of the transmission device; wherein.

[0024] In the first driving mode, the relative positions between the first limiting structure and the second limiting structure are disengaged, the damping unit is connected to the first transmission point of the transmission assembly, and the rotating shaft drives the damping unit to rotate synchronously when it rotates autonomously.

[0025] In the second driving mode, the relative position between the fifth limiting structure and the third limiting structure is locked, the damping unit is separated from the first transmission part of the transmission assembly, and the rotating member drives the moving member and the rotating shaft to rotate independently.

[0026] In the second driving mode, the relative position between the fifth limiting structure and the third limiting structure is locked, the damping unit is separated from the first transmission part of the transmission assembly, and the rotating member drives the moving member and the rotating shaft to rotate independently.

[0027] In one possible implementation, the second driving member includes,

[0028] A fixed ring is provided on the first transmission part of the transmission assembly. The fixed ring is sleeved on the outside of the rotating shaft and is fixedly connected to the rotating shaft. The fixed ring and the moving part are spaced apart.

[0029] The second elastic element is sleeved outside the rotating shaft. The first end of the second elastic element abuts against the fixed ring, and the second end of the second elastic element abuts against the moving element.

[0030] In one embodiment, the movable member has a second limiting groove formed on the side near the fixed ring. The second limiting groove is formed by a first limiting ring and a second limiting ring spaced apart along the first direction. The first limiting ring is disposed away from the fixed ring relative to the second limiting ring. The first movable structure is disposed on the side of the first limiting ring away from the fixed ring.

[0031] The damping unit has a moving ring on the side near the moving part, and the moving ring is located in the second limiting groove between the first limiting ring and the second limiting ring.

[0032] In one possible implementation, a limiting plate is provided between the moving ring and the first moving structure; wherein,

[0033] In the first driving mode, the moving ring separates from the limiting plate;

[0034] In the second driving mode, the moving ring abuts against the limiting plate, and the limiting plate is located between the first limiting ring and the second limiting ring.

[0038] Compared to existing technologies, in the first drive mode, the damping unit moves closer to the first transmission point of the transmission assembly via a moving unit, and the damping unit is connected to the first transmission point of the transmission assembly. In this mode, the transmission assembly rotates synchronously with the damping unit under manual conditions to reduce the transmission speed of the transmission assembly. In the second drive mode, the damping unit separates from the first transmission point of the transmission assembly. In this mode, the transmission assembly rotates independently under automatic conditions, and the damping unit does not participate in the rotation. Furthermore, the number of transmission cycles of the transmission assembly in the first drive mode is significantly less than that in the second drive mode, thus reducing the use of the damping unit and increasing its service life.

[0039] Therefore, this application has the characteristics of reasonable structure and convenient use. Attached Figure Description

[0084] In the first driving mode, the relative position between the fifth limiting structure and the third limiting structure is disengaged, the damping unit is connected to the first transmission point of the transmission assembly, and the rotating shaft drives the damping unit to rotate synchronously when it rotates autonomously.

[0089] Example 1:

[0090] Please refer to the attached document. Figure 1 To be continued Figure 4 The diagram illustrates a specific embodiment of the damping component 10 of this application. The damping component 10 of this application is used to slow down the transmission speed of mechanical kinetic energy, thereby achieving stable transmission of the target object. The damping component 10 of this application is applied in the automotive manufacturing field. In one embodiment, the damping component 10 of this application is applied to the transmission of an in-vehicle display terminal. Further, the damping component 10 of this application is used to realize the rotation of the in-vehicle display terminal.

[0091] Appendix Figure 1 This is a schematic diagram of a structure between the damping component 10 and the transmission component 20 under the first driving mode of this application. (Attached) Figure 2 This is a schematic diagram of a structure between the damping component 10 and the transmission component 20 in the second driving mode of this application. Please refer to the attached diagram. Figure 1 and appendix Figure 2 As shown, the first direction X of this application refers to the length direction of the damping component 10, that is, the direction of the damping component 10 from left to right or from right to left. In this application, the second moving structure 220 is positioned to the left of the first moving structure 210, and the first moving structure 210 is positioned to the right of the second moving structure 220. The second direction Y of this application refers to the height direction of the damping component 10, that is, the direction of the damping component 10 from top to bottom or from bottom to top. In this application, the damping shell 120 is positioned above the second limiting structure 320, and the second limiting structure 320 is positioned below the damping shell 120.

[0092] Please refer to the attached document. Figure 1 and appendix Figure 2As shown, the damping component 10 of this application is used to connect with the first transmission point 712 of the transmission component 20. Depending on whether the damping component 10 is connected to the first transmission point 712 of the transmission component 20, it can be divided into a first driving mode and a second driving mode. In the first driving mode, the damping unit 100 is connected to the first transmission point 712 of the transmission component 20, and the transmission component 20 is in manual mode. In manual mode, the damping unit 100 participates in the operation to slow down the rotational speed of the transmission component 20. In the second driving mode, the damping unit 100 is disconnected from the first transmission point 712 of the transmission component 20, and the transmission component 20 is in automatic mode, where the transmission component 20 operates independently. Therefore, the damping unit 100 only participates in the operation in the first driving mode and does not participate in the operation in the second driving mode, reducing the operating time of the damping unit 100 and further extending its service life.

[0093] Please refer to the attached document. Figure 1 and appendix Figure 2 As shown, the damping assembly 10 of this application includes a damping unit 100. A first rotation axis 110 is disposed through the damping unit 100 along a first direction X. The damping unit 100 can rotate around the first rotation axis 110 under the drive of the transmission assembly 20. The damping unit 100 includes a damping shell 120 and a damping core 130. The damping core 130 is installed inside the damping shell 120, and the damping core 130 interacts with the damping shell 120 to reduce the rotational speed of the damping core 130. Furthermore, a second transmission point is provided on the damping core 130, and a first transmission point 712 is provided on the transmission assembly 20. The second transmission point on the damping core 130 is connected to the first transmission point 712 on the transmission assembly 20 to form a first driving mode.

[0094] In one embodiment, the transmission method between the first transmission point 712 and the second transmission point is friction transmission or gear transmission. Further, the transmission between the first transmission point 712 and the second transmission point is gear transmission, the relative position between the damping component 10 and the transmission component 20 is fixed before movement, and the transmission component 20 is in a stopped transmission state. Therefore, the relative position between the second transmission point of the damping core 130 and the first transmission point 712 of the transmission component 20 is fixed, and misalignment will not occur.

[0095] Please refer to the attached document. Figure 1 and appendix Figure 2 As shown, the damping assembly 10 of this application also includes a moving unit 200, which is used to drive the damping unit 100 to move along the first direction X, so as to drive the second transmission part of the damping unit 100 to approach or move away from the first transmission part 712 of the transmission assembly 20. Under the movement of the damping unit 100, the damping unit 100 and the transmission assembly 20 include a first driving mode and a second driving mode.

[0096] The moving unit 200 includes a first moving structure 210 and a second moving structure 220. The first moving structure 210 and the second moving structure 220 are located at opposite ends of the damping unit 100 along a first direction X. The first moving structure 210 drives the damping unit 100 to move toward the first transmission point 712 of the transmission assembly 20, thereby achieving a transmission connection between the second transmission point on the damping core 130 and the first transmission point 712 on the transmission assembly 20. The second moving structure 220 drives the damping unit 100 to move away from the first transmission point 712 of the transmission assembly 20, thereby achieving a separation between the second transmission point on the damping core 130 and the first transmission point 712 on the transmission assembly 20.

[0097] After the transmission assembly 20 rotates to its position, the second moving structure 220 automatically drives the damping unit 100 away from the first transmission point 712 of the transmission assembly 20. The specific operation process will be further described in Embodiment 2. In one embodiment, the second moving structure 220 is an elastic structure. Further, the second moving structure 220 is a spring or an elastic sheet. The second moving structure 220 is an elastic sheet, which has a bent structure, and there is a compression space between the elastic sheets.

[0098] The first moving structure 210 is a manually driven structure, allowing the user to manually drive the first moving structure 210 to move the damping unit 100 along the first direction X. The specific structure of the first moving structure 210 will be detailed in the appendix. Figure 7 Further explanation is provided below.

[0099] Please refer to the attached document. Figure 1 and appendix Figure 2 As shown, to further achieve unidirectional rotation of the damping unit 100, the damping assembly 10 of this application is also provided with a limiting unit 300. In the prior art, the unidirectional rotation of the damping unit 100 is achieved by a built-in unidirectional bearing. However, the damping unit 100 of this application is bidirectionally rotatable, and the unidirectional rotation of the damping assembly 10 is achieved by an external limiting unit 300.

[0100] Please refer to the attached document. Figure 1 and appendix Figure 2 As shown, the limiting unit 300 of this application includes a first limiting structure 310 and a second limiting structure 320. A plurality of first limiting structures 310 are arranged circumferentially on the surface of the damping shell 120. The second limiting structure 320 is located on one side of the damping shell 120 along the second direction Y. The first limiting structure 310 and the second limiting structure 320 interact to ensure that the damping shell 120 rotates unidirectionally around the first rotation axis 110. The specific structures of the first limiting structure 310 and the second limiting structure 320 will be described in the appendix. Figure 3 and appendix Figure 4 Further details are provided below.

[0101] Appendix Figure 3 This is a schematic diagram of a structure between the damping unit 100 and the limiting unit 300 of this application. (Attached) Figure 4 This is another structural schematic diagram of the damping unit 100 and the limiting unit 300 in this application. Please refer to the attached diagram. Figure 3 and appendix Figure 4 As shown, the rotation direction of the damping core 130 in this application includes forward rotation A around the first rotation axis 110 and reverse rotation B around the first rotation axis 110, with the rotation directions of forward rotation A and reverse rotation B being opposite. When the damping core 130 rotates forward A, the transmission component rotates in the reverse direction. At this time, the second limiting structure 320 cannot constrain the first limiting structure 310, and the damping core 130 rotates synchronously with the damping shell. When the damping core 130 rotates in the reverse direction B, the transmission component rotates forward. At this time, the second limiting structure 320 and the first limiting structure 310 constrain each other. At this time, the damping core 130 rotates within the damping shell 120, thereby reducing the rotational speed of the transmission component 20.

[0102] The first limiting structure is a first limiting protrusion disposed on the surface of the damping housing 120. The bottom of the first limiting protrusion is in contact with the surface of the damping housing 120. The first limiting protrusion has ramps 314 on both sides, which are arranged around the circumference of the damping housing 120 and are tangent to the damping housing 120. The first limiting protrusion is provided with a first limiting groove 311 through a first direction. The first limiting groove 311 includes two corresponding first side surfaces 312 and second side surfaces 313. The first side surface 312 to the second side surface 313 is in the positive direction, and the second side surface 313 to the first side surface 312 is in the negative direction. The first side surface 312 and the second side surface 313 are arranged around the circumference of the damping housing 120. The inclination angle of the first side surface 312 is greater than the inclination angle of the second side surface 313, and the radial height of the first side surface 312 is greater than the radial height of the second side surface 313.

[0103] The second limiting structure 320 includes a second limiting protrusion 321 and a first elastic member 322. The first end of the first elastic member 322 is connected to the second limiting protrusion 321, and the second end of the first elastic member 322 abuts against a fixed point. The second limiting protrusion 321 has a protrusion facing the damping housing 120, which is adapted to the first limiting groove 311. When the damping core 130 rotates, the protrusion can escape from the first limiting groove 311 when it interacts with the first side surface 312, at which point the damping core 130 and the damping housing 120 rotate synchronously. When the damping core 130 rotates, the protrusion is confined in the first limiting groove 311 when it interacts with the second side surface 313, and the damping core 130 rotates independently within the damping housing.

[0104] In the initial state, the protrusion of the second limiting protrusion 321 is located in the first limiting groove 311 of a certain first limiting protrusion. When entering the first driving mode, if the transmission component 20 rotates in the reverse direction B, the damping core 130 rotates in the forward direction A around the first rotation axis 110. After the protrusion of the second limiting protrusion 321 abuts against the first limiting surface 422, since the protrusion of the second limiting protrusion 321 cannot restrict the rotation of the first limiting protrusion, the second limiting protrusion 321 floats upward and leaves the first limiting groove 311 in the current first limiting protrusion. At this time, the damping shell and the damping core 130 rotate synchronously until the second limiting protrusion 321 enters the next first limiting groove 311 in the rotation direction and the rotation ends.

[0105] In the initial state, the protrusion of the second limiting protrusion 321 is located in the first limiting groove 311 of a certain first limiting protrusion. When entering the first driving mode, if the transmission component 20 rotates in the forward direction A, the damping core 130 rotates in the reverse direction B around the first rotation axis 110. After the protrusion of the second limiting protrusion abuts against the second limiting surface 610, the protrusion of the second limiting protrusion 321 restricts the rotation of the first limiting protrusion. At this time, the damping shell remains stationary, and the damping core 130 rotates independently inside the damping shell.

[0107] Please refer to the attached document. Figure 5 To be continued Figure 12 The diagram illustrates a specific embodiment of the transmission device of this application. This transmission device is used to transmit mechanical kinetic energy and is applied in the automotive manufacturing field. In one embodiment, the transmission device is used to drive an in-vehicle display terminal. Furthermore, the transmission device is used to realize the rotation of the in-vehicle display terminal.

[0108] Please refer to the attached document. Figure 5 As shown, the first direction X of this application refers to the length direction of the transmission device, that is, the direction of the transmission device from left to right or from right to left. In this application, the second moving structure 220 is disposed to the left of the limiting plate 650, and the limiting plate 650 is disposed to the right of the second moving structure 220. The second direction Y of this application refers to the front-to-back direction of the transmission device, that is, the direction of the transmission device from front to back or from back to front. In this application, the damping component 10 is disposed to the rear of the rotating shaft 410, and the rotating shaft 410 is disposed to the front of the damping component 10.

[0109] Appendix Figure 5 This is a schematic diagram of one possible structure of the transmission device of this application. Please refer to the attached diagram. Figure 5As shown, the transmission device of this application includes a transmission component 20. In this application, the transmission component 20 can realize manual rotation and automatic rotation. The manual rotation of the transmission component 20 corresponds to the first driving mode of the damping component 10, and the automatic rotation of the transmission component 20 corresponds to the second driving mode of the damping component 10.

[0110] Please refer to the attached document. Figure 5 As shown, the transmission assembly 20 of this application includes a rotating shaft 410. As a shaft-type component, the rotating shaft 410 rotates circumferentially around its axis through power transmission from other components. Both automatic and manual transmission in this application are achieved through the rotating shaft 410. Other components in this application are rotatably connected, fixedly connected, or axially movable connected to the rotating shaft 410.

[0111] Please refer to the attached document. Figure 5 As shown, the transmission assembly 20 of this application further includes a rotating member 420 and a first driving member 500. The rotating member 420 is rotatably connected to the rotating shaft 410. Further, the rotating member 420 is sleeved outside the rotating shaft 410 and rotates around the rotating shaft 410. The rotating member 420 itself does not transmit power; it needs to be used in conjunction with the moving member 600 to transmit power to the rotating shaft 410. The first driving member 500 is connected to the rotating member 420. Further, under the drive of the first driving member 500, the rotating member 420 rotates. If the rotating member 420 and the moving member 600 cooperate at this time, an automatic transmission state of the transmission assembly 20 is formed, that is, the first driving member 500 can directly drive the rotating shaft 410 to rotate through the cooperation of the rotating member 420 and the moving member 600.

[0112] Please refer to the attached document. Figure 1 As shown, the transmission assembly 20 of this application also includes a movable member 600 and a second driving member 710. The movable member 600 is disposed on one side of the rotating member 420. The movable member 600 and the rotating shaft 410 are axially movable and connected, and the rotating shaft 410 and the movable member 600 are synchronously rotatably connected. The second driving member 710 is used to drive the movable member 600 to move closer to the rotating member 420, while the first moving structure 210 is used to drive the movable member 600 away from the rotating member 420.

[0113] Furthermore, the movable member 600 of this application has a second limiting groove 620 formed on the side near the fixed ring 711, and the damping unit 100 has a movable ring 140 on the side near the movable member 600. The movable ring 140 is located in the second limiting groove 620 so as to realize that the movable member 600 and the damping unit 100 move synchronously.

[0114] In one embodiment, the movable member 600 and the rotating shaft 410 are connected by a spline, the spline including an internal spline and an external spline, the movable member 600 is provided with one of the internal spline and the external spline, and the rotating shaft 410 is provided with the other of the internal spline and the external spline.

[0115] In one embodiment, the movable member 600 is connected to the rotating shaft 410 by a guide key. The guide key is fixedly connected to one of the movable member 600 and the rotating shaft 410, and the guide key is axially slidably connected to the other of the movable member 600 and the rotating shaft 410.

[0116] Please refer to the attached document. Figure 5 As shown, the transmission assembly 20 of this application includes a first limiting member. The first limiting member is used to lock or disengage the relative position between the rotating member 420 and the moving member 600. The first limiting member is used in conjunction with the second driving member 710, the first moving structure 210 and the third driving member 820 to form the automatic transmission state, the manual transmission state and the limit position state of the transmission assembly 20.

[0117] Furthermore, the movable member 600 moves away from the rotating member 420 under the drive of the first movable structure 210, and under the drive of the third driving member 820, the first limiting member 720 between the rotating member 420 and the movable member 600 is misaligned to form a manual transmission state of the transmission assembly 20. In the manual transmission state, the relative position of the first limiting member between the rotating member 420 and the movable member 600 is disengaged, and the rotating shaft 410 achieves autonomous rotation by manually rotating the first connecting member 810. Under the drive of the rotating shaft 410, the relative position of the first limiting member between the rotating member 420 and the movable member 600 is correspondingly set, and under the drive of the second driving member 710, the movable member 600 moves closer to the rotating member 420 to form an automatic transmission state of the transmission assembly 20. In the automatic transmission state, the first limiting member between the rotating member 420 and the movable member 600 is locked together, and the first driving member 500 sequentially drives the rotating member 420, the movable member 600, the rotating shaft 410, and the first connecting member 810 to rotate.

[0118] Please refer to the attached document. Figure 5As shown, the second driving member 710 of this application includes a fixing ring 711, which is sleeved on the outside of the rotating shaft 410 and fixedly connected to the rotating shaft 410. The fixing ring 711 is spaced apart from the moving member 600. The second driving member 710 also includes a second elastic member 713, which is sleeved on the outside of the rotating shaft 410. The first end of the second elastic member 713 abuts against the moving member 600, and the second end of the second elastic member 713 abuts against the fixing ring 711. Thus, the second elastic member 713 always provides a driving force for the moving member 600 to move axially toward the rotating member 420. When the first limiting member 720 is correspondingly set between the rotating member 420 and the moving member 600, the moving member 600 moves closer to the rotating member 420 under the drive of the first elastic member 322.

[0119] Furthermore, the first transmission part 712 of the transmission assembly 20 is disposed on the fixed ring 711.

[0120] Please refer to the attached document. Figure 5 As shown, the transmission assembly 20 of this application also includes a first connector 810, the rotating shaft 410 is connected to the animal to be transmitted through the first connector 810, and the first connector 810 rotates synchronously with the rotating shaft 410.

[0121] Furthermore, the first connector 810 is fixedly connected to the rotating shaft 410, and the fixed connection point between the first connector 810 and the rotating shaft 410 is located on the circumferential surface of the rotating shaft 410 or the end face of the rotating shaft 410.

[0122] Please refer to the attached document. Figure 5 As shown, the transmission assembly 20 of this application also includes a third driving member 820. The third driving member 820 is sleeved on the outside of the rotating shaft 410 and is fixedly connected to the rotating shaft 410. The third driving member 820 is used to drive the rotating shaft 410 to rotate circumferentially.

[0123] Appendix Figure 6 This is a structural schematic diagram of the first driving component 500 of this application. Please refer to the attached diagram. Figure 6 As shown, the driving connection between the first driving member 500 and the rotating member 420 in this application can be either belt pulley transmission or gear meshing transmission. When the first driving member 500 and the rotating member 420 are connected by belt pulley transmission, a rotating belt is sleeved between the first driving member 500 and the rotating member 420, and the first driving member 500 drives the rotating member 420 to rotate. When the first driving member 500 and the rotating member 420 are connected by gear meshing transmission, the first driving member 500 has a driving gear, and the rotating member 420 is a driven gear, and the first driving member 500 drives the rotating member 420 to rotate.

[0124] In one embodiment, the first driving member 500 and the rotating member 420 are connected by gear meshing. Further, the first driving member 500 includes a drive motor 510 and a power transmission mechanism 520, which are respectively connected to the drive motor 510 and the rotating member 420.

[0125] The power transmission mechanism 520 includes a first transmission worm 521, a transmission turbine 522, and a second transmission worm 523. The first transmission worm 521 is located at the output end of the drive motor 510, which directly drives the first transmission worm 521 to rotate. The transmission turbine 522 meshes with the first transmission worm 521 to achieve synchronous rotation between them. The second transmission worm 523 is connected to the transmission turbine 522 to achieve synchronous rotation between them. Furthermore, the second transmission worm 523 is connected to the rotating component 420, thereby enabling the first drive component 500 to drive the rotating component 420 to rotate. The meshing between the second transmission worm 523 and the rotating component 420 achieves self-locking between the rotating component 420 and the first drive component 500, preventing the moving component 600 from driving the rotating component 420 to rotate in manual transmission mode.

[0126] Appendix Figure 7 This is a structural diagram of one of the first drive structures applied for. Please refer to the attached diagram. Figure 7 As shown, the first moving structure 210 of this application includes a rotating handle 211 and a rotating body 212. The rotating handle 211 is disposed on one side of the rotating body 212 and is fixedly connected to the rotating body 212. A second rotating shaft 410 line 214 is provided on the rotating body 212. When the user turns the rotating handle 211, the rotating body 212 rotates around the second rotating shaft 410 line 214, thereby further driving the moving part 600 to move.

[0127] In this application, the first driving structure can also be a pull rod, which pulls the moving part 600 away from the rotating part 420.

[0128] Appendix Figure 8 This is a schematic diagram of one possible structure of the third driving component 820 of this application. Please refer to the attached diagram. Figure 8 As shown, the third driving component 820 of this application includes a fixing sleeve 821, which is sleeved on the outside of the rotating shaft 410 and is fixedly connected to the rotating shaft 410.

[0129] In one embodiment, the fixing sleeve 821 is fixedly connected to the rotating shaft 410 by a key connection. The fixed connection between the fixing sleeve 821 and the rotating shaft 410 is not limited to a key connection; other methods such as welding can also be used.

[0130] The third driving member 820 also includes a third elastic member 822, which is sleeved outside the fixed sleeve 821. The first end and / or the second end of the third elastic member 822 extend outward and abut against the limiting point to generate a rotational force that drives the rotating shaft 410 to rotate circumferentially. In the automatic transmission state, the third elastic member 822 of the transmission assembly 20 of this application is compressed, thereby storing force for the circumferential rotation of the rotating shaft 410. The circumferential rotation of the rotating shaft 410 is for the purpose of creating a misalignment between the relative positions of the third limiting structure 721 and the fifth limiting structure 723. When the transmission assembly 20 of this application switches from the automatic transmission state to the manual transmission state, the third elastic member 822 releases the stored force for circumferential rotation, thereby creating a misalignment between the third limiting structure 721 and the fifth limiting structure 723.

[0131] In one embodiment, the third elastic element 822 is a torsion spring.

[0132] In one embodiment, the first end of the third elastic member 822 is fixedly connected to the fixed sleeve 821, and the second end of the third elastic member 822 extends outward and abuts against the limiting position.

[0133] Appendix Figure 9 This is a structural schematic diagram of the movable component 600 of this application. Figure 10 This is another structural diagram of the movable component 600 in this application. Please refer to the attached diagram. Figure 9 and appendix Figure 10 As shown, the movable member 600 of this application has a through hole, through which it is sleeved on the outside of the rotating shaft 410. A keyway is provided in the through hole to facilitate key connection with the rotating shaft 410. The first end of the movable member 600 has a second limiting surface 610, and the second end of the movable member 600 has a second limiting groove 620. That is, the second limiting groove 620 is formed on the side of the movable member 600 near the fixed ring 711. The second limiting groove 620 is formed by a first limiting ring 630 and a second limiting ring 640 spaced apart along the first direction X. The first limiting ring 630 and the second limiting ring 640 are set to protrude from the outer surface of the movable member 600. The first limiting ring 630 is set away from the fixed ring 711 relative to the second limiting ring 640. The first moving structure 210 is set on the side of the first limiting ring 630 away from the fixed ring 711. When the first moving structure 210 contacts the first limiting ring 630, it can drive the movable member 600 to move.

[0134] In this application, the transmission assembly 20 switches from an automatic transmission state to a limit position state, and the moving member 600 rotates along a third direction, which in this application is either clockwise or counterclockwise. A fourth limiting structure 722, a second limiting surface 610, and a fifth limiting structure 723 are sequentially provided on one end face of the moving member 600 along the third direction.

[0135] Furthermore, a fourth limiting structure 722 is disposed on the second limiting surface 610, and the fourth limiting structure 722 is part of the first limiting member 720. The fourth limiting structure 722 is one of a limiting protrusion and a limiting groove. In this application, the limiting groove and the limiting protrusion are adapted to each other. A fifth limiting structure 723 is also disposed on the second limiting surface 610, and the fifth limiting structure 723 is of the same type as the fourth limiting structure 722.

[0136] In one embodiment, both the fourth limiting structure 722 and the fifth limiting structure 723 are limiting grooves. Furthermore, the axial depth of the fourth limiting structure 722 is greater than the axial depth of the fifth limiting structure 723, and the radial width of the fourth limiting structure 722 is greater than the radial width of the fifth limiting structure 723.

[0137] The fourth limiting structure 722 and the fifth limiting structure 723 are each composed of two limiting side surfaces and a limiting bottom surface. The limiting side surfaces are located on both sides of the fourth limiting structure 722 and the fifth limiting structure 723, and the limiting bottom surface is located at the bottom of the fourth limiting structure 722 and the fifth limiting structure 723. An angle is formed between the two limiting side surfaces and the limiting bottom surface to provide guidance for the third limiting structure 721. The angle between the limiting side surface and the limiting bottom surface of the fourth limiting structure 722 is the same as the angle between the limiting side surface and the limiting bottom surface of the fifth limiting structure 723. In this application, the fact that the angle between the limiting side surface and the limiting bottom surface of the fourth limiting structure 722 is the same as the angle between the limiting side surface and the limiting bottom surface of the fifth limiting structure 723 is only one embodiment of this application, and is intended to ensure a good fit between the third limiting structure 721 and the fourth limiting structure 722 and the fifth limiting structure 723.

[0138] Appendix Figure 11 This is a schematic diagram of one possible structure of the rotating component 420 of this application. (Attached) Figure 12 This is a schematic diagram of another structure of the rotating component 420 in this application. Please refer to the attached diagram. Figure 11 and appendix Figure 12 As shown, a positioning hole 423 is provided through the rotating member 420 of this application. The rotating member 420 is sleeved on the outside of the rotating shaft 410 through the positioning hole 423, and the rotating member 420 is rotatably connected around the rotating shaft 410. In this application, the rotating member 420 cannot directly drive the rotating shaft 410 to rotate. One end face of the rotating member 420 is a first limiting surface 422, and a third limiting structure 721 is disposed on the first limiting surface 422. The third limiting structure 721 is a part of the first limiting member 720, and the third limiting structure 721 is another type of limiting protrusion and limiting groove. In this application, the limiting groove and the limiting protrusion are adapted to each other.

[0139] In one embodiment, the third limiting structure 721 is a limiting protrusion. The axial depth of the third limiting structure 721 is not less than the axial depth of the fourth limiting structure 722, and the radial width of the third limiting structure 721 is not less than the radial width of the fourth limiting structure 722.

[0140] The third limiting structure 721 consists of two side surfaces and a top surface, with an angle between the two side surfaces and the top surface. This angle is consistent with the angle between the limiting side surfaces and the limiting bottom surfaces of the fourth and fifth limiting structures 722 and 723. In this application, the fact that the angle between the two side surfaces and the top surface of the third limiting structure 721 is consistent with the angle between the limiting side surfaces and the limiting bottom surfaces of the fourth and fifth limiting structures 722 and 723 is merely one embodiment of this application, intended to ensure a good fit between the third limiting structure 721 and the fourth and fifth limiting structures 722 and 723.

[0141] In one embodiment, the rotating member 420 is coaxially arranged with the rotating shaft 410.

[0142] Appendix Figure 2 This is a schematic diagram of a structure between the damping component 10 and the transmission component 20 in the second driving mode of this application. Please refer to the attached diagram. Figure 2 As shown, in the second drive mode between the damping component 10 and the transmission component 20, the transmission component 20 is simultaneously in manual transmission mode. Please refer to the appendix. Figure 2As shown, when switching from automatic to manual transmission, the first moving structure 210 rotates to the right and abuts against the first limiting ring 630, driving the moving member 600 to move to the left. During the movement, the third limiting structure 721 gradually disengages from the fourth limiting structure 722. Until the third limiting structure 721 is completely disengaged from the fourth limiting structure 722, the moving member 600 rotates due to the presence of the third driving member 820, thus creating a misalignment between the third limiting structure 721 and the fourth limiting structure 722. Furthermore, due to the presence of the second driving member 710, the second driving member 710 drives the moving member 600 to move towards the rotating member 420, causing the third limiting structure 721 to abut against the second limiting surface 610. In this case, the animal to be transferred and the first connecting member 810 can be manually rotated, thereby rotating the rotating shaft 410 and the moving member 600, causing the angle of the animal to be transferred to change. The manual transmission state means that the angle change of the animal to be transferred is driven manually, rather than by the first driving member 500. Simultaneously, during the movement, the first limiting ring 630 contacts the moving ring 140 and drives the damping unit 100 to move toward the first transmission point 712 on the fixed ring 711 until the second transmission point on the damping unit 100 engages with the first transmission point 712 on the fixed ring 711, thereby compressing the second moving structure 220. At this time, due to the misalignment between the third limiting structure 721 and the fourth limiting structure 722, the engagement between the second transmission point on the damping unit 100 and the first transmission point 712 on the fixed ring 711 can be maintained. Under this condition, the transmission component 20 can drive the damping core 130 to rotate. The transmission component 20 rotates in the opposite direction (B), and the damping core 130 rotates in the forward direction (A). At this time, the second limiting structure 320 cannot constrain the first limiting structure 310, and the damping core 130 and the damping shell rotate synchronously. When the damping core 130 rotates in the reverse direction (B), the transmission component 20 rotates in the forward direction (A). At this time, the second limiting structure 320 and the first limiting structure 310 constrain each other. The damping core 130 rotates inside the damping shell, which serves to reduce the rotation speed of the transmission component 20.

[0143] When a further increase in the rotation angle of the object to be transmitted is needed in manual transmission mode, the object to be transmitted and the first connecting member 810 are rotated manually, thereby rotating the rotating shaft 410 and the moving member 600, so that the rotation angle of the object to be transmitted is further increased until the third limiting structure 721 enters the fifth limiting structure 723. The fifth limiting structure 723 is designed to give the user a certain sense of awareness during manual rotation, thus reminding the user that the object to be transmitted reaches its maximum rotation angle after the third limiting structure 721 enters the fifth limiting structure 723. The extreme position state is an extreme case of manual transmission mode. In this application, if it is necessary to switch from manual transmission to automatic transmission, it is necessary to rotate the B-type transmission object and the first connecting member 810 in the reverse direction until the third limiting structure 721 and the fourth limiting structure 722 are correspondingly set. When the third limiting structure 721 and the fourth limiting structure 722 are correspondingly set, due to the presence of the second driving member 710, the second driving member directly drives the fourth limiting structure 722 and the third limiting structure 721 to form a self-locking mechanism. At this time, the second transmission part of the damping unit 100 and the first transmission part 712 of the transmission assembly 20 are always in a meshing state.

[0144] Appendix Figure 1 This is a schematic diagram of a structure between the damping component 10 and the transmission component 20 in the first driving mode of this application. Please refer to the attached diagram. Figure 1 As shown, the rotating shaft 410 is further rotated by the animal to be transmitted, which simultaneously drives the moving part 600 to rotate until the third limiting structure 721 corresponds to the fourth limiting structure 722. Under the drive of the second elastic element 713, the fourth limiting structure 722 enters the third limiting structure 721 to enter the automatic transmission state. At this time, the moving part 600 moves towards the rotating part 420. At this time, the second limiting ring 640 abuts against the moving ring 140, separating the second transmission part of the damping core 130 from the first transmission part 712 on the fixed ring 711. Further, the second moving structure 220 drives the damping unit 100 to move towards the limiting plate 650 until the moving ring 140 abuts against the limiting plate 650. At this time, the limiting plate 650 is located between the first limiting ring 630 and the second limiting ring 640, which can ensure that the moving ring 140 does not contact the first limiting ring 630 and the second limiting ring 640 when the transmission assembly 20 is automatically transmitting, thereby ensuring the stability of the transmission assembly 20 during automatic transmission. Furthermore, the presence of the second moving structure 220 and the limiting plate 650 ensures the relative stability of the position of the damping unit 100 in the second driving mode, thereby preventing the damping unit 100 from moving relative to the others.

[0146] Please refer to the attached document. Figure 13 To be continued Figure 15As shown, a specific embodiment of the vehicle-mounted display terminal of this application is presented. In this application, the vehicle-mounted display terminal is a specific application of the transmission component 20, but the application of the transmission component 20 of this application is not limited to the vehicle-mounted display terminal. Other components that need to realize both manual and automatic transmission can also be implemented using the transmission component 20 of this application.

In this application, the display component 30 is a cathode ray tube display or a liquid crystal display, etc. The vehicle-mounted display terminal also includes a connecting plate 40, which is disposed on the back of the display component 30. The connecting plate 40 is connected to the first connecting member 810 of the transmission component 20, and the transmission component 20 is used to drive the display component 30 to move around the rotation axis 410.

[0149] In one embodiment, a second connecting member 50 can be provided between the first connecting member 810 and the connecting plate 40 to form a multi-link structure. That is, the first connecting member 810 is connected to the connecting plate 40, and the second connecting member 50 is connected to both the connecting plate 40 and the storage box 60. The multi-link structure allows the display component 30 to move around the transmission component 20 in a curved or linear motion trajectory.

[0151] Please refer to the attached document. Figure 13 To be continued Figure 15The diagram illustrates a structural schematic of a vehicle according to this application. In this application, the cooperation between the in-vehicle display terminal and the storage box 60 is a specific application of the in-vehicle display terminal. In the prior art, when a transmission device is used with the display component 30, the transmission device is limited to switching the display component 30 between landscape and portrait modes. However, in this application, the cooperation between the display component 30 and the storage box 60 allows the opening or closing of the opening of the storage cavity 61 within the storage box 60, thus enriching the usage forms of the in-vehicle display terminal.

When the display assembly 30 rotates, its back surface is used to close or open the opening. A through hole is also provided on the side of the storage box 60 with the receiving cavity 61, through which a connecting plate 40 is connected to the display assembly 30.
