[0060] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the protection scope of this application.

[0061] This application proposes a lifting mechanism. Figures 1 to 10 These are some embodiments of this application. Please refer to the accompanying drawings, in which the X direction is the first direction, the Z direction is the second direction, and the Y direction is the third direction, and the X, Y, and Z directions are mutually perpendicular. In the following description, the first direction Z, the second direction Y, and the third direction X will be used.

[0062] Please see Figures 1 to 3 In some embodiments of this application, the lifting mechanism includes a first plate 1 and a second plate 2. The second plate 2 is disposed on one side of the first plate 1 in a first direction X. One of the first plate 1 and the second plate 2 is connected to a first device, and the other is connected to a second device. That is, in one embodiment of this application, the first plate 1 is connected to the first device, and the second plate 2 is connected to the second device. In another embodiment of this application, the second plate 2 is connected to the first device, and the first plate 1 is connected to the second device.

[0063] It should be noted that the specific types of the first and second devices in the embodiments of this application are not limited. They can be mechanical equipment, transportation equipment, or office equipment, etc. For example, the first device in the embodiments of this application can be a display screen, an operation panel, a workbench, etc., and the second device can be a vehicle, an office desk, or a machine tool, etc.

[0064] In some embodiments of this application, the first device is a display screen and the second device is a vehicle for description; that is, in one embodiment of this application, the first plate 1 is connected to the display screen 18 and the second plate 2 is mounted on the vehicle body; in another embodiment of this application, the second plate 2 is connected to the display screen 18 and the first plate 1 is mounted on the vehicle body.

[0065] In some embodiments of this application, the lifting mechanism further includes a guide structure 4, which includes a guide member 41 and a mating member 42. The mating member 42 is movably mounted on the guide member 41 and can move in the second direction Z. One of the guide member 41 and the mating member 42 is connected to the first plate 1, and the other is connected to the second plate 2. That is, the first plate 1 and the second plate 2 can move relative to each other in the second direction Z through the mutual cooperation of the guide member 41 and the mating member 42.

[0066] The first plate 1 and the second plate 2 move relative to each other in the second direction Z, which can adjust the height of the display screen 18 inside the vehicle.

[0067] In one embodiment of this application, the guide 41 is connected to the first plate 1, and the mating part 42 is connected to the second plate 2; in another embodiment of this application, the guide 41 is connected to the second plate 2, and the mating part 42 is connected to the first plate 1.

[0068] In the technical solution of this application, a guide structure 4 is provided between the first plate 1 and the second plate 2. The mating part 42 in the guide structure 4 is movably installed on the guide part 41 in the guide structure 4 and can move in the second direction Z, so that the height of the display screen 18 in the vehicle can be adjusted. The overall structure of the lifting mechanism is simple and can realize the function of adjusting the height of the display screen 18, reducing the overall size of the display screen 18 equipped with the lifting mechanism and improving the utilization rate of the vehicle interior space.

[0069] It is understood that, in one embodiment, when the first device is a display screen 18 and the second device is an office desk, the lifting mechanism allows the height of the display screen 18 on the office desk to be adjusted. The overall structure of the lifting mechanism is simple and can achieve the function of adjusting the height of the display screen 18, reducing the overall size of the display screen 18 equipped with the lifting mechanism and improving the space utilization of the office desk. In another embodiment, when the first device is an operation panel and the second device is a machine tool, the lifting mechanism allows the height of the operation panel on the machine tool to be adjusted. The overall structure of the lifting mechanism is simple and can achieve the function of adjusting the height of the operation panel, reducing the overall size of the operation panel equipped with the lifting mechanism and improving the space utilization of the machine tool. The relevant features of the lifting mechanism described below can all be applied to devices for adjusting the relative positional relationship between the first device and the second device in the second direction Z, and will not be elaborated on here.

[0070] It should be added that, since the mating part 42 is movably mounted on the guide part 41, in one embodiment of this application, the first plate 1 and the second plate 2 can be connected and fixed in the first direction X by assembling the mating part 42 with the guide part 41; in another embodiment of this application, the mating part 42 and the guide part 41 may only serve a guiding function, and the first plate 1 and the second plate 2 can be connected and fixed in the first direction X by other components located in the lifting mechanism.

[0071] In some embodiments of this application, the second plate 2 is provided with at least one first mounting groove 3 on the side of the first plate 1 in the first direction X; that is, the guide 41 or mating part 42 connected to the second plate 2 can be installed in the first mounting groove 3. This arrangement reduces the overall size of the lifting mechanism and the display screen 18 in the first direction X, thereby reducing the size of the display screen 18 equipped with the lifting mechanism in the first direction X, thereby improving the utilization rate of the vehicle interior space.

[0072] Please see Figure 4 In some embodiments of this application, the first plate 1 is provided with a second mounting groove 5 on the side of the second plate 2 in the first direction X; the guide 41 or mating part 42 connected to the first plate 1 is installed in the second mounting groove 5. In this embodiment, the guide 41 and the mating part 42 are installed in the first mounting groove 3 and the second mounting groove 5 respectively, thereby further reducing the relative distance between the first plate 1 and the second plate 2 in the first direction X, reducing the space occupied by the lifting mechanism in the first direction X, and improving the space utilization rate.

[0073] In some embodiments of this application, the first plate 1 is connected to the display screen 18, the mating part 42 is installed in the second mounting groove 5 on the first plate 1, the second plate 2 is installed on the vehicle body, and the guide part 41 is installed in the first mounting groove 3 on the second plate 2.

[0074] The assembly method between mating part 42 and first plate 1, and between guide part 41 and second plate 2 is not limited; it can be snap-fit, glued, or screwed, etc.

[0075] Please refer to it again. Figure 4 In some embodiments of this application, the mating member 42 is connected to the first plate 1 and the guide member 41 is connected to the second plate 2 by screws. The screw connecting the mating member 42 and the first plate 1 passes through the first plate 1 on the side of the first plate 1 away from the mating member 42, thereby screwing it to the mating member 42. The screw connecting the guide member 41 and the second plate 2 passes through the second plate 2 on the side of the second plate 2 away from the guide member 41, thereby screwing it to the guide member 41.

[0076] It should be added that the first plate 1 and the second plate 2 are provided with slots in the corresponding screw nut parts, so that the screw nut parts do not protrude from the surface of the first plate 1 and the second plate 2, so that the overall structure of the lifting mechanism is more beautiful and compact, and the overall size of the lifting mechanism in the first direction X is reduced.

[0077] Please see Figures 4 to 6 In some embodiments of this application, the mating member 42 is provided with a guide groove 6 on the side near the guide member 41 in the first direction X. The guide groove 6 extends along the second direction Z and penetrates the mating member 42. The guide member 41 extends along the second direction Z, and at least a portion of the guide member 41 is located in the guide groove 6. The guide groove 6 is provided so that the mating member 42 can move along the extension direction of the guide member 41. The surface of the guide member 41 is parallel to the groove wall of the adjacent guide groove 6, so that the relative movement between the mating member 42 and the guide member 41 will not be stuck.

[0078] In addition, the simple assembly method between the guide 41 and the mating part 42 results in a low production cost for the guide 41 and the mating part 42.

[0079] In some embodiments of this application, the guide member 41 is connected to the second plate 2 and disposed in the first mounting groove 3, and the mating member 42 is connected to the first plate 1; wherein, at least a portion of the mating member 42 is located in the first mounting groove 3; in this embodiment, by providing that at least a portion of the mating member 42 is located in the first mounting groove 3, the relative distance between the first plate 1 and the second plate 2 in the first direction X is shortened, the space occupied by the lifting mechanism in the first direction X is reduced, so as to improve the space utilization rate.

[0080] In some embodiments of this application, a second mounting groove 5 is provided on the first plate 1 and a mating member 42 is installed in the second mounting groove 5. A first mounting groove 3 is provided on the second plate 2 and a guide member 41 is installed in the first mounting groove 3. At least a portion of the guide member 41 is located in the guide groove 6 of the mating member 42 and at least a portion of the mating member 42 extends into the first mounting groove 3, thereby shortening the relative distance between the first plate 1 and the second plate 2 in the first direction X, reducing the space occupied by the lifting mechanism in the first direction X, and improving space utilization.

[0081] In some embodiments of this application, the guide structure 4 further includes at least one limiting member 43, which is connected to the mating member 42; in the first direction X, at least a portion of the guide member 41 is located between the limiting member 43 and the mating member 42; thus, the limiting member 43 can restrict the guide member 41 and the mating member 42 from separating from each other in the first direction X, thereby restricting the first plate 1 and the second plate 2 from separating from each other in the first direction X.

[0082] The guide structure 4, in addition to having the function of guiding the first plate 1 and the second plate 2 to move relative to each other in the second direction Z, also has the function of restricting the separation of the first plate 1 and the second plate 2 in the first direction X.

[0083] It is understandable that, since at least part of the guide member 41 is located within the guide groove 6, the relative groove wall of the guide groove 6 in the third direction Y will stop the guide member 41, thereby restricting the relative movement of the first plate 1 and the second plate 2 in the third direction Y. That is, the mutual cooperation of the guide member 41, the mating member 42 and the limiting member 43 makes the guide member 41 and the mating member 42 only able to move relative to each other in the second direction Z, and unable to move relative to each other in the first direction X and the third direction Y, thereby enhancing the stability of the display screen 18 installed in the vehicle.

[0084] Please see Figure 4 In some embodiments of this application, the limiting member 43 is disposed in the guide groove 6; the guide member 41 is provided with a first limiting groove 7, which is opposite to the limiting member 43 and is used to accommodate the limiting member 43; that is, in this embodiment, the cooperation between the limiting member 43 and the first limiting groove 7 can restrict the guide member 41 from coming out of the guide groove 6, and since the limiting member 43 is located in the guide groove 6, the overall size of the lifting mechanism will not increase, so as to reduce the space occupied by the lifting mechanism in the vehicle.

[0085] In some embodiments of this application, the mating member 42 is provided with a receiving groove 8 on the groove wall of the guide groove 6, and the limiting member 43 is disposed in the receiving groove 8. At least a portion of the limiting member 43 protrudes from the receiving groove 8 and extends into the first limiting groove 7. That is, in this embodiment, the limiting member 43 and the mating member 42 can be movably disassembled and assembled, thereby facilitating the replacement and maintenance of the limiting member 43.

[0086] In some embodiments of this application, the first limiting groove 7 passes through the guide member 41 in the second direction Z, so that the guide member 41 and the mating member 42 can be relatively separated. After the guide member 41 and the mating member 42 are relatively separated, the limiting member 43 can be dislodged from the receiving groove 8, thereby realizing the maintenance and replacement of the limiting member 43.

[0087] In some embodiments of this application, the guide member 41 is provided with first limiting grooves 7 on both opposite sides in the third direction Y, and the mating member 42 is provided with receiving grooves 8 at the positions corresponding to the two first limiting grooves 7. The first limiting grooves 7 and receiving grooves 8 provided opposite to each other in the third direction Y can limit the limiting member 43, thereby realizing the limiting among the guide member 41, the mating member 42 and the limiting member 43, so that the guide member 41 and the mating member 42 can only move relative to each other in the second direction Z, and cannot move relative to each other in the first direction X and the third direction Y, thereby enhancing the stability of the display screen 18 installed in the vehicle.

[0088] In some embodiments of this application, the receiving groove 8 penetrates at least one side of the mating member 42 in the second direction Z; this arrangement facilitates the operator or operating tool to assemble the limiting member 43 into the receiving groove 8 in the second direction Z.

[0089] In some embodiments of this application, the guide structure 4 further includes a stop 44 connected to the mating member 42. At least part of the stop 44 blocks the opening of the receiving groove 8 in the second direction Z to restrict the limiting member 43 from dislodging from the receiving groove 8 in the second direction Z. By providing the stop 44, the limiting member 43 is prevented from falling off between the guide member 41 and the mating member 42 under the action of gravity during the use of the lifting mechanism.

[0090] In some embodiments of this application, the receiving groove 8 penetrates through the mating member 42 on both sides of the mating member 42 in the second direction Z, so that a stop member 44 is installed on both sides of the mating member 42 in the second direction Z.

[0091] In some embodiments of this application, the limiting member 43 includes a plurality of limiting sub-parts 431, which are arranged sequentially in the second direction Z. With this arrangement, a suitable number of limiting sub-parts 431 can be selected and assembled into the receiving groove 8 according to the size of the mating member 42 in the second direction Z.

[0092] In some embodiments of this application, in order not to affect the relative sliding of the guide 41 and the mating member 42, the limiting sub-part 431 is provided to extend along the second direction Z.

[0093] Please see Figure 5 and Figure 7 In some embodiments of this application, the guide member 41 is provided with a groove 9 on the side near the second plate 2 in the first direction X; the second plate 2 is provided with a protrusion 10 at the bottom of the first mounting groove 3, and the protrusion 10 and the groove 9 cooperate with each other in the first direction X; through the cooperation between the groove 9 on the guide member 41 and the protrusion 10 on the second plate 2, it is convenient for the operator and the operating tool to position and install the guide member 41 in the first mounting groove 3; at the same time, the cooperation between the groove 9 and the protrusion 10 will not increase the overall thickness of the guide member 41 and the second plate 2 in the first direction X after the guide member 41 is assembled onto the second plate 2.

[0094] In some embodiments of this application, the lifting mechanism further includes a drive structure 11, which includes a drive part 111 and a connecting part 112. One of the drive part 111 and the connecting part 112 is connected to the first plate 1, and the other is connected to the second plate 2. The drive part 111 drives the connecting part 112 to move along the second direction Z. By driving the connecting part 112, the first plate 1 can move relative to the second plate 2.

[0095] In some embodiments of this application, the driving part 111 includes a driving member 1111 and a transmission member 1112. The driving member 1111 is mounted on the second plate 2, and the transmission member 1112 extends along the second direction Z and is pulsatorically connected to the output end of the driving member 1111. The connecting part 112 includes a driven member 1121, which is mounted on the first plate 1 and pulsatorically connected to the transmission member 1112. The transmission member 1112 can drive the driven member 1121 to move in the second direction Z, thereby enabling the first plate 1 to move relative to the second plate 2 in the second direction Z.

[0096] In some embodiments of this application, the driving component 1111 includes a driving motor, the transmission component 1112 includes a transmission screw, and the driven component 1121 includes a screw nut; wherein, the driving motor is mounted on the second plate 2; the transmission screw extends along the second direction Z and is connected to the output end of the driving motor; the screw nut is mounted on the first plate 1 and screwed onto the transmission screw; that is, in this embodiment, the driving motor can drive the transmission screw to rotate, and the first plate 1 can move relative to the second plate 2 in the second direction through the cooperation of the transmission screw and the screw nut.

[0097] In some embodiments of this application, the second plate 2 is further provided with a mounting base 19 on the side opposite to the first plate 1 in the first direction X, and the driving member 1111 is correspondingly mounted on the mounting base 19.

[0098] Please see Figure 10 In some embodiments of this application, the drive unit 111 further includes a reducer 1113 disposed between the drive motor and the transmission screw.

[0099] In some embodiments of this application, the output shaft of the drive motor is equipped with a worm gear, and the reducer 1113 is a worm gear reducer, with the output end of the reducer 1113 integrally connected to the transmission screw.

[0100] In some embodiments of this application, two guide structures 4 are provided, and are respectively located on both sides of the drive structure 11 in the third direction Y, so that the drive structure 11 is more stable when driving the first plate 1 to move in the second direction Z.

[0101] Please see Figures 7 to 9In some embodiments of this application, a through groove 12 extending along the first direction X is provided on the second plate 2, and the transmission member 1112 is located in the through groove 12; a mounting part 13 is provided on the side of the first plate 1 near the first plate 1 in the first direction X, at least a portion of the mounting part 13 extends into the through groove 12, and a slot 14 is provided on the mounting part 13, and the driven member 1121 is correspondingly engaged in the slot 14; in this embodiment, by providing the transmission member 1112 located in the through groove 12, and the driven member 1121 is mounted on the mounting part 13 and cooperates with the transmission member 1112, the structural arrangement of the driven member 1121 and the transmission member 1112 will not occupy too much space in the first plate 1 and the second plate 2 in the first direction X, thereby reducing the overall thickness of the lifting mechanism in the first direction X, thereby improving the utilization rate of the vehicle interior space.

[0102] Since the transmission member 1112 has a certain length in the second direction Z so that the driven member 1121 can move a certain distance along the transmission member 1112 in the second direction Z, thereby adjusting the height of the display screen 18, the through slot 12 extends a certain length in the second direction Z so that at least part of the transmission member 1112 and the driven member 1121 can be located in the through slot 12 so as not to interfere with the movement of the driven member 1121.

[0103] In some embodiments of this application, the follower 1121 is covered with a first buffer 20, that is, the first buffer 20 is located between the groove wall of the slot 14 and the follower 1121, thereby reducing impact noise and absorbing installation errors of the follower 1121.

[0104] In some embodiments of this application, the lifting mechanism further includes at least one elastic element 15 extending along the second direction Z. One end of the elastic element 15 is connected to the second plate 2, and the other end is connected to the first plate 1. During the upward movement of the display screen 18 along the second direction Z, the drive motor needs to overcome the gravity of the display screen 18 and the first plate 1, resulting in a large operating current. During the downward movement of the display screen 18 along the second direction Z, the direction of gravity of the display screen 18 and the first plate 1 is the same as the direction of movement, and the drive motor only needs to overcome friction, resulting in a small operating current. To make the operation of the drive motor smoother and to reduce the operating current of the drive motor, the elastic element 15 is provided. During the upward movement of the display screen 18 along the second direction Z, the elastic element 15 provides an upward pulling force on the first plate 1.

[0105] In some embodiments of this application, the elastic element 15 is a tension spring.

[0106] In some embodiments of this application, the number of elastic members 15 is two, and they are respectively disposed on opposite sides of the second plate 2 in the third direction Y.

[0107] In some embodiments of this application, one of the first plate 1 and the second plate 2 is provided with a second limiting groove 16, and the other is provided with a locking protrusion 17. The second limiting groove 16 extends along the second direction Z, and at least a portion of the locking protrusion 17 is located within the second limiting groove 16. By providing the locking protrusion 17 located within the second limiting groove 16, the movement stroke of the display screen 18 in the second direction Z can be limited.

[0108] In some embodiments of this application, the protrusion 17 is disposed on the first plate 1, and the second limiting groove 16 is formed on the second plate 2.

[0109] The locking protrusion 17 moves upward along the second direction Z within the second limiting groove 16. When it reaches one end of the second limiting groove 16, the locking protrusion 17 abuts against the second plate 2, thereby restricting the relative movement of the first plate 1 and the second plate 2. The control device stops the drive member 1111 from rotating by detecting the stall current. Similarly, the locking protrusion 17 moves downward along the second direction Z within the second limiting groove 16. When it reaches the other end of the second limiting groove 16, the locking protrusion 17 abuts against the second plate 2, thereby restricting the relative movement of the first plate 1 and the second plate 2. The control device stops the drive member 1111 from rotating by detecting the stall current.

[0110] In some embodiments of this application, a second buffer 21 is provided on the protrusion 17 to reduce the impact and noise when the protrusion 17 contacts the second plate 2.

[0111] This application also proposes a display device, including a lifting mechanism and a display screen 18. The lifting mechanism is described above.

[0112] The display screen 18 is connected to either the first plate 1 or the second plate 2.

[0113] In some embodiments of this application, the display screen 18 is integrally formed with the first plate 1 or the second plate 2.

[0114] This application also proposes a vehicle including a display device, as described above. Since this vehicle adopts all the technical solutions of all the above embodiments, it has at least the beneficial effects brought about by the technical solutions of the above embodiments, which will not be repeated here.
