Description

Technical Field

[0001] This invention relates to the field of new energy vehicle parts manufacturing technology, specifically to an electric slide rail mechanism for new energy vehicle seats. Background Technology

[0002] Currently, car seats rely on electric sliding rails to adjust their fore-and-aft position. The sliding rails include a lower sliding rail fixed to the car body and an upper sliding rail connected to the seat. The upper sliding rail can slide back and forth relative to the lower sliding rail. The seat moves forward and backward synchronously with the upper sliding rail. There are power supply and other wiring harnesses connecting the seat and the car body. The wiring harness needs to constantly change its relative position as the seat is adjusted forward and backward to meet the power supply requirements of the seat's electric adjustment.

[0003] A search revealed that patent CN206938516U discloses an electric slide rail assembly for automotive seats. This patent uses an electrically controlled dual-axis motor to drive a gearbox and a lead screw, thereby adjusting the seat position. However, during the adjustment process, the dual-axis motor moves synchronously with the seat. The dual-axis motor needs to be connected to components fixed on the vehicle body via power harnesses, etc., and the patent does not address the proper handling of the harness storage. As the dual-axis motor moves with the seat, various harnesses may become tangled or interfere with the slide rail, thus posing a safety hazard. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to overcome the defects of the prior art and provide an electric sliding rail mechanism for new energy vehicle seats, which improves driving safety by setting a drag chain to restrict the wiring harness that moves with the seat.

[0005] To solve the above-mentioned technical problems, the technical solution of the present invention is: an electric slide rail mechanism for a new energy vehicle seat, comprising:

[0006] Glide path;

[0007] A main sliding component is provided corresponding to the lower slide rail. The main sliding component includes a main sliding drive and a main sliding mechanism provided on the corresponding lower slide rail. An upper slide rail is provided on the main sliding mechanism. The main sliding drive is connected to the main sliding mechanism to drive the main sliding mechanism to move, thereby driving the upper slide rail to move laterally through the main sliding mechanism.

[0008] The seat base is mounted on the upper slide rail;

[0009] A storage box is provided on one side of the lower slide rail. The storage box has a receiving groove and a sliding guide groove. A controller is provided on the storage box. A drive harness for connecting the power supply and the main sliding drive component is connected to the controller.

[0010] Switching devices are disposed on the seat base;

[0011] A connector, one end of which is connected to the seat base;

[0012] The cable chain installed on the storage box has one end as a fixed end, which is fixed in the receiving groove of the storage box. A portion of the other end of the cable chain is movably received in the receiving groove and then slides through the sliding guide groove, and then connects to the other end of the connector.

[0013] A connecting harness is used to transmit control signals between the controller and the switching device. The connecting harness passes through the connector and the cable chain. When the seat base is moved, the seat base synchronously drives the cable chain to move synchronously along the moving direction of the seat base through the connector.

[0014] Furthermore, in order to better store the wire harness, the sliding guide groove includes a U-shaped groove and a straight groove. One end of the U-shaped groove is connected to the receiving groove, and the other end of the U-shaped groove is connected to one end of the straight groove. The other end of the straight groove passes through the storage box and communicates with the outside. The storage box is provided with an adjustment mechanism, which includes a first adjustment member and a second adjustment member that are slidably disposed on the storage box in the horizontal direction.

[0015] The first adjusting component is connected to the second adjusting component via a connecting block, the controller is mounted on the second adjusting component, and the fixed end of the drag chain is fixedly connected to the second adjusting component;

[0016] The first adjusting member and the second adjusting member are respectively provided with a U-shaped part that cooperates with each other, and a U-shaped groove is formed between the two U-shaped parts for the drag chain to bend and move;

[0017] The first and second adjusting members are adapted to be moved laterally to adjust the position of the U-shaped groove on the storage box, thereby adjusting the length of the straight groove and the receiving groove in the lateral direction.

[0018] Furthermore, the adjustment mechanism also includes an adjustment drive mechanism disposed on the storage box for moving the first adjustment member and the second adjustment member laterally. The adjustment drive mechanism is connected to the first adjustment member to move the first adjustment member in a straight line in the lateral direction, and then drives the second adjustment member to move in a straight line in the lateral direction synchronously through the connecting block.

[0019] Furthermore, the main sliding mechanism includes a first threaded rod rotatably mounted on the lower slide rail and a first nut connected to the first threaded rod. A transmission sleeve is mounted on the first nut, and the transmission sleeve is detachably connected to the corresponding upper slide rail.

[0020] A sliding rod is provided on the lower slide rail, and the upper slide rail is slidably connected to the sliding rod.

[0021] Furthermore, for flexibility, a switching component is provided on the upper slide rail, the switching component including:

[0022] A first switching component is provided on the upper slide rail, the first switching component being adapted to connect or disconnect the upper slide rail from the corresponding transmission sleeve;

[0023] A second switching component is disposed on the upper slide rail, the second switching component being adapted to engage the upper slide rail with the corresponding sliding rod to restrict the lateral movement of the upper slide rail or to disconnect the connection between the upper slide rail and the corresponding sliding rod, so that the upper slide rail slides laterally on the sliding rod.

[0024] Furthermore, the first switching component includes:

[0025] At least one first docking block is vertically slidably disposed on the upper slide rail. The transmission sleeve is provided with a first docking groove corresponding to the first docking block. The first docking block is adapted to be moved to extend into or out of the corresponding first docking groove.

[0026] A first switching drive mechanism is provided on the upper slide rail, and the first switching drive mechanism is connected to the first docking block to move the first docking block linearly in the vertical direction.

[0027] Furthermore, the first switching drive mechanism includes a drive rod that is slidably disposed on the upper slide rail in the lateral direction, an active inclined slider that is fixedly disposed on the drive rod and corresponds to the first docking block, and a driven inclined slider that is fixedly disposed on the first docking block and corresponds to the active inclined slider and is in contact with the corresponding active inclined slider in the vertical direction through an inclined surface. The drive rod is adapted to be moved in the lateral direction by being actuated, thereby synchronously driving the corresponding active inclined slider to move, thereby driving the corresponding first docking block to move in the vertical direction through the cooperation of the inclined surfaces between the active inclined slider and the driven inclined slider.

[0028] Furthermore, the second switching component includes:

[0029] At least one second docking block is slidably disposed on the upper slide rail along the longitudinal direction. The sliding rod is provided with a plurality of second docking grooves arranged at intervals along the transverse direction and cooperating with the second docking block. The second docking block is adapted to be moved linearly in the longitudinal direction to extend into or extend out of one of the second docking grooves.

[0030] A second switching drive mechanism is provided on the upper slide rail, which is adapted to move the second docking block linearly in the longitudinal direction.

[0031] Furthermore, the second switching drive mechanism includes a drive ring that is slidably disposed on the upper slide rail in the lateral direction. The drive ring is provided with a drive block corresponding to the second docking block. The end of the second docking block that is longitudinally away from the sliding rod is provided with a mating block. The mating block is provided with a first driving inclined surface. The drive block is provided with a second driving inclined surface that mates with the first driving inclined surface.

[0032] The drive ring has a first station during lateral movement. When the drive ring is moved laterally to the first station, the second mating block on the corresponding mating block is disengaged from the second mating groove by the pushing and cooperating of the first drive inclined surface and the second drive inclined surface.

[0033] Furthermore, the second switching drive mechanism also includes an elastic component corresponding to the second docking block. The elastic component includes a telescopic rod and a telescopic spring. The two ends of the telescopic rod are respectively connected to the upper slide rail and the mating block. The telescopic spring is disposed outside the corresponding telescopic rod, and the two ends of the telescopic spring are respectively connected to the upper slide rail and the mating block.

[0034] The drive ring also has a second station during lateral movement. When the drive ring is moved laterally to the second station, the first drive inclined surface and the second drive inclined surface disengage or partially contact each other, and the second mating block on the corresponding mating block is engaged in the corresponding second mating groove under the action of the telescopic spring.

[0035] By adopting the above technical solution, the present invention has the following beneficial effects:

[0036] After pressing the corresponding button on the switching device, the signal is fed back to the controller through the connecting harness. The controller then activates the main sliding drive, which drives the main sliding mechanism to operate, thereby moving the upper slide rail laterally to adjust the position of the seat base. By pressing different buttons on the switching device, the seat base can move in different directions laterally. During the movement of the seat base, the connecting piece and the cable chain move linearly in the same direction. In this embodiment, the connecting piece can compensate for the height difference between the switching device and the cable chain, allowing the cable chain to maintain horizontal movement. When the seat base moves away from the storage box, the seat base pulls part of the cable chain out of the storage box, reducing the amount of cable chain contained in the receiving slot. When the seat base moves closer to the storage box, the seat base extends part of the cable chain outside the storage box into the storage box, increasing the amount of cable chain contained in the receiving slot. The connecting harness is always located inside the cable chain and the connecting piece, avoiding exposure of the connecting harness. Moreover, the cable chain's constraint prevents tangling, effectively protecting the connecting harness. Attached Figure Description

[0062] To make the content of this invention easier to understand, the invention will be further described in detail below with reference to specific embodiments and accompanying drawings.

[0063] Example 1: As Figure 1-4 As shown, an electric sliding rail mechanism for a new energy vehicle seat includes:

[0064] Glide rail 1;

[0065] A main sliding component is provided corresponding to the lower slide rail 1. The main sliding component includes a main sliding drive 11 and a main sliding mechanism 12 provided on the corresponding lower slide rail 1. An upper slide rail 13 is provided on the main sliding mechanism 12. The main sliding drive 11 is connected to the main sliding mechanism 12 to drive the main sliding mechanism 12 to move, thereby driving the upper slide rail 13 to move laterally through the main sliding mechanism 12.

[0066] Seat base 14 is mounted on upper slide rail 13;

[0067] A storage box 2 is provided on one side of the lower slide rail 1. The storage box 2 is provided with a receiving groove 39 and a sliding guide groove. A controller 21 is provided on the storage box 2. A drive harness for connecting the power supply and the main sliding drive component 11 is connected to the controller 21.

[0068] A switch device 22 is disposed on the seat base 14;

[0069] Connector 26, one end of connector 26 is connected to seat base 14;

[0070] A drag chain 23 is provided on the storage box 2. One end of the drag chain 23 is a fixed end 24, which is fixed in the receiving groove 39 of the storage box 2. A portion of the other end of the drag chain 23 is movably received in the receiving groove 39 and then slides through the sliding guide groove, and then connects to the other end of the connector 26.

[0071] A connecting harness is used to transmit control signals between the controller 21 and the switching device 22. The connecting harness is passed through the connector 26 and the cable chain 23. When the seat base 14 is moved, the seat base 14 drives the cable chain 23 to move synchronously along the moving direction of the seat base 14 through the connector 26.

[0072] Specifically, the sliding rail 1 and the storage box 2 are fixedly mounted on the vehicle body.

[0073] Specifically, the main sliding drive component 11 can be a drive motor;

[0074] The drive harness includes a motor harness and a power harness. The controller 21 is connected to the drive motor through the motor harness and to the vehicle power supply fixed on the vehicle body through the power harness. In this embodiment, the drive harness is not installed in the cable chain 23 and does not move with the seat base 14.

[0075] In this embodiment, pressing the corresponding button on the switch device 22 sends a signal back to the controller 21 via the connecting harness. The controller 21 then activates the main sliding drive 11, which in turn drives the main sliding mechanism 12, thereby causing the upper slide rail 13 to move laterally to adjust the position of the seat base 14. Pressing different buttons on the switch device 22 moves the seat base 14 in different lateral directions. During the movement of the seat base 14, the connecting member 26 and the drag chain 23 move linearly in the same direction. In this embodiment, the connecting member 26 can compensate for the height difference between the switch device 22 and the drag chain 23. The difference in degree allows the cable chain 23 to maintain horizontal movement during movement. When the seat base 14 moves away from the storage box 2, the seat base 14 pulls part of the cable chain 23 out of the storage box 2, reducing the number of cable chains 23 accommodated in the receiving groove 39. When the seat base 14 moves closer to the storage box 2, the seat base 14 extends part of the cable chain 23 located outside the storage box 2 into the storage box 2, increasing the number of cable chains 23 accommodated in the receiving groove 39. The connecting wire harness is always located within the cable chain 23 and the connector 26, avoiding exposure of the connecting wire harness. Moreover, the cable chain 23 restricts the wire harness from winding, effectively protecting the connecting wire harness.

[0076] like Figure 5-6 As shown, the sliding guide groove includes a U-shaped groove 33 and a straight groove 37. One end of the U-shaped groove 33 is connected to the receiving groove 39, and the other end of the U-shaped groove 33 is connected to one end of the straight groove 37. The other end of the straight groove 37 passes through the storage box 2 and communicates with the outside. An adjustment mechanism is provided on the storage box 2. The adjustment mechanism includes a first adjustment member 3 and a second adjustment member 31 that are slidably disposed on the storage box 2 in the horizontal direction.

[0077] The first adjusting member 3 is connected to the second adjusting member 31 via a connecting block. The controller 21 is installed on the second adjusting member 31. The fixed end 24 of the drag chain 23 is fixedly connected to the second adjusting member 31.

[0078] The first adjusting member 3 and the second adjusting member 31 are respectively provided with a U-shaped part 32 that cooperates with each other, and a U-shaped groove 33 is formed between the two U-shaped parts 32 for the drag chain 23 to bend and move.

[0079] The first adjusting member 3 and the second adjusting member 31 are adapted to be moved laterally to adjust the position of the U-shaped groove 33 on the storage box 2, thereby adjusting the length of the straight groove 37 and the receiving groove 39 in the lateral direction.

[0080] It should be noted that the drag chain 23 is specifically set in the storage box 2 in the following state: starting from the fixed end 24, the fixed end 24 of the drag chain 23 is fixed in the receiving groove 39 of the storage box 2, then part of the drag chain 23 is bent in the receiving groove 39, and then the drag chain 23 enters and passes through the U-shaped groove 33 from one end, and then exits from the other end of the U-shaped groove 33 into the straight groove 37.

[0081] In this embodiment, before the cable chain 23 is installed, the adjustment mechanism is adjusted according to the total length of the cable chain 23 and the travel of the seat base 14. When the original straight storage length of the storage box 2 is insufficient to accommodate the cable chain 23, the first adjustment member 3 and the second adjustment member 31 are activated to move the position of the U-shaped groove 33 laterally, thereby increasing the length of the receiving groove 39 and the straight groove 37 in the lateral direction for accommodating the cable chain 23, while the bending radius of the U-shaped groove 33 remains unchanged. After the adjustment is completed, the first adjustment member 3, the second adjustment member 31, the controller 21 and the U-shaped groove 33 remain fixed relative to the storage box 2. When the seat base 14 moves laterally, the seat base 14 drives the cable chain 23 to move synchronously through the connector 26. The cable chain 23 moves in the straight groove 37, the U-shaped groove 33 and the receiving groove 39. The part of the cable chain 23 stored in the receiving groove 39 is adaptively adjusted according to the moving distance and moving direction of the cable chain 23, thereby realizing the retraction or release of the cable chain 23.

[0082] Specifically, such as Figure 1 As shown, the storage box 2 is provided with a through groove 311 for the connector 26 to move. The through groove 311 is located directly above the straight groove 37. The end of the drag chain 23 connected to the connector 26 is set as the movable end 25. When the movable end 25 of the drag chain 23 moves into the straight groove 37, the connector 26 slides on the through groove 311.

[0083] It should be noted that the size of the through groove 311 matches that of the connector 26. The size of the through groove 311 is smaller than that of the straight groove 37, so that the drag chain 23 located in the straight groove 37 cannot be released from the storage box 2 through the through groove 311.

[0084] Specifically, after the cable chain 23 is installed, the second adjusting member 31 does not need to move further and is fixed in its current position. At this time, the position of the controller 21 is fixed, and then a drive harness of suitable length is selected to connect to the main sliding drive member 11 and the power supply.

[0085] like Figure 5-6As shown, the adjustment mechanism also includes an adjustment drive mechanism disposed on the storage box 2 for moving the first adjustment member 3 and the second adjustment member 31 in the lateral direction. The adjustment drive mechanism is connected to the first adjustment member 3 to move the first adjustment member 3 in a lateral linear motion, and then drives the second adjustment member 31 to move in a lateral linear motion synchronously through the connecting block.

[0086] Specifically, such as Figure 6 As shown, the adjustment drive mechanism includes an adjustment threaded rod 310 rotatably mounted on the storage box 2 and an adjustment nut connected to the adjustment threaded rod 310. The first adjustment member 3 is mounted on the adjustment nut. The adjustment threaded rod 310 is adapted to be rotated, thereby driving the first adjustment member 3 to move linearly along the axial direction (i.e., laterally) of the adjustment threaded rod 310.

[0087] Example 2: Figure 7-9 As shown, this embodiment further includes the following structure based on embodiment one: the main sliding mechanism 12 includes a first threaded rod 15 rotatably mounted on the lower slide rail 1 and a first nut connected to the first threaded rod 15. A transmission sleeve 16 is mounted on the first nut, and the transmission sleeve 16 is detachably connected to the corresponding upper slide rail 13.

[0088] A sliding rod 17 is provided on the lower slide rail 1, and the upper slide rail 13 is partially slidably connected to the sliding rod 17.

[0089] Specifically, the main sliding drive component 11 is a drive motor. The output end of the drive motor is coaxially connected to the first threaded rod 15 to drive the first threaded rod 15 to rotate, thereby driving the transmission sleeve 16 to move along the axis (i.e., the lateral direction) of the first threaded rod 15, and thus driving the upper slide rail 13 and the seat base 14 to move synchronously. During the movement, the upper slide rail 13 slides on the sliding rod 17. The self-locking engagement of the threads between the first threaded rod 15 and the first nut achieves the lateral limitation of the upper slide rail 13.

[0090] like Figure 10-11 As shown, a switching component is provided on the upper slide rail 13. The switching component includes:

[0091] A first switching component 4 is provided on the upper slide rail 13. The first switching component 4 is adapted to connect or disconnect the upper slide rail 13 from the corresponding transmission sleeve 16.

[0092] A second switching component 5 is provided on the upper slide rail 13. The second switching component 5 is adapted to connect the upper slide rail 13 with the corresponding sliding rod 17 to restrict the upper slide rail 13 from moving laterally or to disconnect the connection between the upper slide rail 13 and the corresponding sliding rod 17, so that the upper slide rail 13 slides laterally on the sliding rod 17.

[0093] In this embodiment, when the movement of the seat base 14 fails to activate the main sliding assembly via the switching device 22, the seat base 14 is disconnected from the main sliding assembly by the actions of the first switching component 4 and the second switching component 5, and position adjustment and self-locking are performed on the sliding rod 17. The specific operation method is as follows:

[0094] The first switching component 4 is activated to disconnect the upper slide rail 13 from the transmission sleeve 16 and maintain this disconnected state. At this time, the upper slide rail 13 is supported on the sliding rod 17. The second switching component 5 first maintains the disconnected state between the upper slide rail 13 and the sliding rod 17, allowing the upper slide rail 13 to slide freely on the sliding rod 17. The seat base 14 is manually adjusted to the desired position. Then, the second switching component 5 is activated to align the upper slide rail 13 with the sliding rod 17, thereby fixing the seat base 14. This allows the seat base 14 to still be manually positioned even after the electronic control fails, improving its flexibility of use.

[0095] like Figure 12 As shown, the first switching component 4 can specifically have the following structure, including:

[0096] At least one first docking block 41 is vertically slidably disposed on the upper slide rail 13. The transmission sleeve 16 is provided with a first docking groove 42 corresponding to the first docking block 41. The first docking block 41 is adapted to be moved to extend into or out of the corresponding first docking groove 42.

[0097] A first switching drive mechanism is provided on the upper slide rail 13. The first switching drive mechanism is connected to the first docking block 41 so that the first docking block 41 moves linearly in the vertical direction.

[0098] In this embodiment, when the transmission sleeve 16 and the upper slide rail 13 are in a docking state, the first docking block 41 extends into the first docking groove 42. When it is necessary to disconnect the transmission sleeve 16 from the upper slide rail 13, the first docking block 41 can be moved vertically out of the first docking groove 42 by the first switching drive mechanism.

[0099] like Figure 12 As shown, the first switching drive mechanism can specifically be the following structure, including a drive rod 43 that is slidably disposed on the upper slide rail 13 in the horizontal direction, an active inclined slider 44 that is fixedly disposed on the drive rod 43 and corresponds to the first docking block 41, and a driven inclined slider 45 that is fixedly disposed on the first docking block 41 and corresponds to the active inclined slider 44 and is in contact with the corresponding active inclined slider 44 in the vertical direction through an inclined surface. The drive rod 43 is adapted to be moved in the horizontal direction by being driven, thereby synchronously driving the corresponding active inclined slider 44 to move, thereby driving the corresponding first docking block 41 to move in the vertical direction through the cooperation of the inclined surfaces between the active inclined slider 44 and the driven inclined slider 45.

[0100] Specifically, such as Figure 12 As shown, a support rod 46 is provided on the upper slide rail 13, and the drive rod 43 is coaxial and slidably connected to the support rod 46 in the transverse direction.

[0101] In this embodiment, as Figure 12 As shown, in the initial state, the first docking block 41 extends into the corresponding first docking groove 42, the transmission sleeve 16 and the upper slide rail 13 are in a docking state, and the actuation drive rod 43 moves forward (i.e., Figure 2 The middle has the direction of the switching device in the horizontal direction or Figure 12 (In the direction indicated by the middle arrow) moves, and through the cooperation between the active inclined slider 44 and the driven inclined slider 45, it drives the corresponding first docking block 41 to move out of the first docking groove 42, so that the transmission sleeve 16 is disconnected from the upper slide rail 13.

[0102] Among them, the active inclined slider 44 and the driven inclined slider 45 are conventional inclined slider mechanisms, and their specific cooperation structure and working principle will not be described in detail here.

[0103] Specifically, such as Figure 12 As shown, the upper slide rail 13 is provided with a guide rod 47 corresponding to the first docking block 41, and the first docking block 41 is slidably mounted on the corresponding guide rod 47 along the vertical direction.

[0104] Specifically, such as Figure 13-14 As shown, a first switching screw 6 is rotatably mounted on the upper slide rail 13. A first switching nut is connected to the first switching screw 6. A first connecting plate 61 is mounted on the first switching nut. The first connecting plate 61 is connected to the drive rod 43. The first switching screw 6 is adapted to be rotated, thereby driving the first connecting plate 61 to move linearly back and forth in the lateral direction.

[0105] In this embodiment, rotating the first switching screw 6 drives the first connecting plate 61 to move back and forth, which in turn drives the drive rod 43 to move. During the movement of the drive rod 43, the first docking block 41 extends into or out of the first docking groove 42 through the cooperation between the active inclined slider 44 and the driven inclined slider 45. The self-locking cooperation of the threads between the first switching screw 6 and the first switching nut restricts the drive rod 43 and the first connecting plate 61 to remain in the specified position.

[0106] Furthermore, a first switching handle 62 is provided on the first switching screw 6. The first switching handle 62 is adapted to be rotated by action, thereby driving the first switching screw 6 to rotate.

[0107] In this embodiment, the first switching handle 62 can be used to better drive the first switching screw 6 to rotate.

[0108] like Figure 15 As shown, the second switching component 5 includes:

[0109] At least one second docking block 51 is slidably disposed on the upper slide rail 13 along the longitudinal direction. A plurality of second docking grooves 52 are provided on the sliding rod 17 along the transverse direction and are arranged at intervals and cooperate with the second docking block 51. The second docking block 51 is adapted to be moved linearly in the longitudinal direction to extend into or out of one of the second docking grooves 52.

[0110] A second switching drive mechanism is provided on the upper slide rail 13. The second switching drive mechanism is adapted to move the second docking block 51 linearly in the longitudinal direction.

[0111] In this embodiment, when the transmission sleeve 16 is connected to the upper slide rail 13 by the first switching component 4, the second switching component 5 holds the second docking block 51 in a position outside the second docking groove 52. When the transmission sleeve 16 is disconnected from the upper slide rail 13 by the first switching component 4, the second switching component 5 continues to hold the second docking block 51 in a position outside the second docking groove 52. After manually pushing the seat base 14 to the required position, the second switching component 5 then inserts the second docking block 51 into one of the second docking grooves 52 at the corresponding position, thereby achieving the connection between the upper slide rail 13 and the sliding rod 17.

[0112] like Figure 16-18 As shown, the second switching drive mechanism can specifically be the following structure, including a drive ring 53 that is slidably disposed on the upper slide rail 13 in the transverse direction, a drive block 54 that corresponds to the second docking block 51 on the drive ring 53, a mating block 55 that is disposed on the end of the second docking block 51 that is longitudinally away from the sliding rod 17, a first driving inclined surface 56 that is disposed on the mating block 55, and a second driving inclined surface 57 that mates with the first driving inclined surface 56 on the drive block 54.

[0113] The drive ring 53 has a first station during lateral movement. When the drive ring 53 is moved laterally to the first station, the second mating block 51 on the corresponding mating block 55 is disengaged from the second mating groove 52 by the pushing and cooperating of the first drive inclined surface 56 and the second drive inclined surface 57.

[0114] Specifically, such as Figure 15-18 As shown, the second switching drive mechanism also includes an elastic component corresponding to the second docking block 51. The elastic component includes a telescopic rod and a telescopic spring 58. The two ends of the telescopic rod are respectively connected to the upper slide rail 13 and the mating block 55. The telescopic spring 58 is disposed outside the corresponding telescopic rod. The two ends of the telescopic spring 58 are respectively connected to the upper slide rail 13 and the mating block 55.

[0115] The drive ring 53 also has a second station during its lateral movement. When the drive ring 53 is moved laterally to the second station, the first drive inclined surface 56 and the second drive inclined surface 57 disengage or partially contact each other, causing the second mating block 51 on the corresponding mating block 55 to be engaged in the corresponding second mating groove 52 under the action of the telescopic spring 58.

[0116] The drive ring 53 has a first station and a second station during its lateral movement, and correspondingly, the second docking block 51 has a disconnection station and a docking station during its longitudinal movement.

[0117] In this embodiment, the drive block 54 is initially positioned at the first work station. Through the pushing engagement of the second drive inclined surface 57 and the first drive inclined surface 56 on the mating block 55, the second mating block 51 cannot enter the second mating groove 52, thus holding the second mating block 51 in the disconnected position. The upper slide rail 13 can slide on the sliding rod 17, adjusting the seat base 14 to the desired position. At this time, the telescopic spring 58 is in a pre-compressed state. When the seat base 14 moves to the desired position, the actuation drive ring 53 moves forward (i.e.,...). Figure 17 (In the direction indicated by the middle arrow) Move to the second station, the first driving inclined surface 56 and the second driving inclined surface 57 disengage or partially contact, so that the driving block 54 releases the restriction on the mating block 55. The telescopic spring 58 pushes the mating block 55 and the second docking block 51 from the disconnected station to the docking station. When the second docking block 51 is at the docking station, the telescopic spring 58 is in its natural state. When the second docking block 51 is aligned with the second docking groove 52 corresponding to the current position of the seat base 14, the second docking block 51 directly extends into the corresponding second docking groove 52 to complete the docking. When the second docking block 51 is not aligned with the second docking groove 52 corresponding to the current position of the seat base 14, the position of the seat base 14 is finely adjusted in the horizontal direction so that the second docking block 51 is aligned with the nearest second docking groove 52 in the moving direction of the finely adjusted seat base 14.

[0118] Specifically, such as Figure 13-14 As shown, a second switching screw 7 is rotatably mounted on the upper slide rail 13. A second switching nut is connected to the second switching screw 7. A second connecting plate 71 is mounted on the second switching nut. The second connecting plate 71 is connected to the drive ring 53. The second switching screw 7 is adapted to be rotated, thereby driving the second connecting plate 71 to move back and forth linearly in the lateral direction, thereby driving the drive ring 53 to move to the first station or the second station.

[0119] In this embodiment, rotating the second switching screw 7 drives the second connecting plate 71 to move back and forth, thereby driving the drive ring 53 to move to the first or second working position, so that the second docking block 51 is located at the disconnection or docking position, and the self-locking engagement of the threads between the second switching screw 7 and the second switching nut restricts the drive ring 53 and the second connecting plate 71 to be held in the specified position.

[0120] Secondly, a second switching handle 72 is provided on the second switching screw 7. The second switching handle 72 is adapted to be rotated by action, thereby driving the second switching screw 7 to rotate.

[0121] In this embodiment, the second switching handle 72 can be used to better drive the second switching screw 7 to rotate.

[0122] Of course, the structure that drives the drive rod 43 to move laterally and the structure that drives the drive ring 53 to move laterally are not limited to the structure in this embodiment, and can also be other structures.

[0123] The specific embodiments described above further illustrate the technical problems, technical solutions, and beneficial effects of the present invention. It should be understood that the above descriptions are merely specific embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
