Description

Technical Field

[0001] The utility model relates to the field of vehicle-mounted displays, and particularly to a display sliding mechanism and an automobile. Background Art

[0002] With the development requirements of the novelty and technology of automobile interiors, more and more vehicle-mounted display products are applied to the scenarios of driving information display. With the further improvement of vehicle intelligence, at present, a sliding connection method between a sliding carriage and a vehicle-mounted display is adopted, and then a sliding connection between the sliding carriage and a slide rail is used to realize the movement and switching of the vehicle-mounted display between the driver's seat and the passenger seat. However, the structure for realizing this sliding connection method is too complex. For example, the connection between the sliding carriage and the slide rail is realized through bearings, the connection between the vehicle-mounted display and the sliding carriage is realized through a base, and the connection between the base and the sliding carriage is realized through a locking rod and a locking hole, etc.

[0003] In addition, since the bottom surface of the sliding carriage is a plane, its contact area with the slide rail is large. Therefore, during the movement of the vehicle-mounted display, the frictional resistance is also large, resulting in a large motor power and a large noise. At the same time, this technical solution can only move and switch between the driver's seat and the passenger seat, and cannot stop at any position. Summary of the Utility Model

[0004] The purpose of the utility model is to solve the technical problems that the frictional resistance of the existing sliding mechanism is large during operation and it cannot stop at any position. The utility model provides a display sliding mechanism, which can reduce the frictional resistance during operation and stop at any position.

[0005] To solve the above technical problems, an embodiment of the utility model discloses a display sliding mechanism, including a housing, including a lead screw nut, and the housing is used for connecting with an external display; a lead screw, connected with the lead screw nut, and one end of the lead screw is used for connecting with an external driving member; a first sliding member, including a connecting portion and a sliding portion, one end of the connecting portion is connected with the housing, and the other end of the connecting portion is connected with the sliding portion; a first sleeve, rotatably sleeved outside the connecting portion; a slide rail, including a chute, the chute extends along the length direction of the lead screw, the first sleeve is limited in the chute and is in rolling connection with the chute wall, and the sliding portion is in sliding connection with the slide rail.

[0006] Adopting the above technical solution, when the lead screw rotates, through the connection between the lead screw and the lead screw nut, the circumferential rotational motion of the lead screw is converted into the linear motion of the lead screw nut. Correspondingly, the housing can also move linearly relative to the lead screw. The connecting portion of the first sliding member is connected with the housing, so the first sliding member can be synchronously in sliding connection with the slide rail.

[0007] The first sleeve is rotatably sleeved outside the connecting portion. Therefore, the first sliding member drives the first sleeve to move linearly relative to the lead screw. During the movement, the first sleeve can rotate, and the outer wall of the first sleeve contacts the groove wall of the chute and generates rolling friction, thereby reducing the movement resistance. Compared with the sliding connection mode of the pulley and the slide rail in the prior art, the rolling connection mode in this solution can reduce the friction resistance during the operation of the display screen sliding mechanism, reduce the motor power, and reduce the noise.

[0008] In addition, during the entire operation of the display screen sliding mechanism, as long as the driving member stops driving, the lead screw also stops rotating, the lead screw nut stops moving, and correspondingly, the housing also stops moving. Then, the first sliding member and the first sleeve also stop sliding. Therefore, the external display screen also stops at the corresponding position. Therefore, the display screen sliding mechanism in this solution can stop the external display screen at any position according to the needs of the user.

[0009] Moreover, in this technical solution, the threaded connection of the lead screw and the lead screw nut can be used to move the in-vehicle display screen between any positions, and the housing is used to connect the display screen and the display screen sliding mechanism. Compared with the prior art, the connection method is simpler, reducing the part cost.

[0010] According to another specific embodiment of the present invention, the display screen sliding mechanism further includes a second sliding member. The second sliding member is sleeved outside the first sleeve, and the second sliding member is rotatably and / or slidably connected to the slide rail; wherein, along the direction perpendicular to the length direction of the lead screw, the second sliding member is disposed on one side of the slide rail and the first sliding member is disposed on the opposite side of the slide rail.

[0011] Adopting the above technical solution, there are two connection methods between the second sliding member and the slide rail. The first is that the second sliding member slides on the slide rail while the second sliding member itself rotates; the second is that the second sliding member only slides on the slide rail and the second sliding member itself does not rotate. Both of these connection methods can reduce the friction resistance during the operation of the display screen sliding mechanism, reduce the motor power, and reduce the noise.

[0012] According to another specific embodiment of the present invention, a first convex portion is provided on the first surface of the second sliding member acting on the slide rail, and the first convex portion contacts the slide rail.

[0013] Adopting the above technical solution, by contacting the slide rail through the first convex portion, the contact area between the second sliding member and the slide rail can be reduced, and the friction resistance can be reduced.

[0014] According to another specific embodiment of the present invention, a groove is provided on the second surface of the sliding portion acting on the slide rail, and one end of the first sleeve is disposed in the groove.

[0015] According to another specific embodiment of the present utility model, a second convex portion is provided on the second surface of the sliding portion that acts on the slide rail, and the second convex portion is in contact with the slide rail.

[0016] By adopting the above technical solution, the contact area between the sliding portion, i.e., the first sliding member, and the slide rail can be reduced through the contact between the second convex portion and the slide rail, thereby reducing the frictional resistance.

[0017] According to another specific embodiment of the present utility model, the display screen sliding mechanism includes a first connecting member and a first gasket. The first gasket is connected to the third surface of the sliding portion through the first connecting member, wherein the second surface and the third surface are correspondingly arranged.

[0018] By adopting the above technical solution, during the operation of the display screen sliding mechanism, due to the existence of frictional resistance, the first sliding member is prone to torsion. At the same time, the first sliding member is made of plastic material and has relatively poor hardness. Once the first sliding member is closely attached to other components (such as the first sleeve), when the first sleeve rotates but the first sliding member cannot rotate, the first sliding member is easily broken by the frictional force between the two. Therefore, a first gasket is provided between the first part and the sliding portion. The material of the first gasket is relatively hard, which can improve the torsional stiffness of the first sliding member.

[0019] According to another specific embodiment of the present utility model, the display screen sliding mechanism includes a first rubber portion, and the first rubber portion is disposed between the first sleeve and the connecting portion.

[0020] By adopting the above technical solution, in the actual production process, it is inevitable that there are errors in the dimensions of the various components in the display screen sliding mechanism. By providing the first rubber portion, the width of the first rubber portion can be reduced by the deformation of the first rubber portion under extrusion pressure, thereby reserving production tolerances for the dimensions of other components (such as the connecting portion, the first sleeve, etc.) during the production process and reducing the process requirements for other components (such as the connecting portion, the first sleeve, etc.).

[0021] According to another specific embodiment of the present utility model, the display screen sliding mechanism includes a second rubber portion and a second gasket. The second gasket is disposed on the fourth surface of the second sliding member, the fourth surface and the first surface are correspondingly arranged, and the second rubber portion is disposed between the fourth surface and one end of the connecting portion.

[0022] With the above technical solution, in the actual production process, it is inevitable that there are errors in the dimensions of the various components in the display sliding mechanism. By providing the second rubber part, the height of the second rubber part can be reduced by the deformation of the second rubber part under the extrusion force, so as to reserve production tolerances for the dimensions of other components (such as the connecting part, the second sliding part, etc.) during the production process, and reduce the process requirements for other components (such as the connecting part, the second sliding part, etc.).

[0023] During the operation of the display sliding mechanism, when the second sliding part slides along the slide rail, the second sliding part itself also rotates axially in the first direction, and at the same time, the first sleeve also rotates axially in the first direction. If the connection between the second sliding part and the first sleeve is relatively tight and the second sliding part is made of plastic with poor hardness, then during the rotation process, the second sliding part is prone to break due to the frictional force between the two. Therefore, a second gasket is provided between the fourth surface and one end of the connecting part. The material of the second gasket is relatively hard, which can improve the torsional stiffness of the second sliding part.

[0024] According to another specific embodiment of the present invention, the slide rail is provided with an installation part, and both ends of the lead screw are connected to the installation part; and / or, the housing further includes a second connecting piece, and the second connecting piece is used to connect to the display screen of the outside world.

[0025] An embodiment of the present invention also discloses an automobile, including:

[0026] The display sliding mechanism described in any one of the above;

[0027] A display screen, connected to the housing of the display sliding mechanism.

[0028] With the above technical solution, by driving the lead screw to rotate, the circumferential rotation of the lead screw can be converted into the linear motion of the display sliding mechanism. Thus, the display sliding mechanism can drive the display screen to move linearly relative to the lead screw through the housing, and the display sliding mechanism in this solution can stop the display screen at any position according to the needs of the user, enhancing the user experience. At the same time, due to the provision of the mutually cooperating first sleeve and the chute, when the lead screw drives the housing to achieve linear motion, through the rolling friction between the first sleeve and the chute, the smoothness of the housing driving the display screen to slide can be further improved and the motion resistance generated during the motion can be reduced.

[0059] To make the objectives, technical solutions, and advantages of the present utility model clearer, the embodiments of the present utility model will be described in further detail below in conjunction with the accompanying drawings.

[0060] Refer to Figure 1 , this application provides an automobile (not shown in the figure), including a display screen sliding mechanism 1, a first structural member 2, and a second structural member 3. Along the second direction Y, the first structural member 2 and the second structural member 3 are spaced apart, and the display screen sliding mechanism 1 is located between the first structural member 2 and the second structural member 3. The display screen sliding mechanism 1 can make the display screen slide between the first structural member 2 and the second structural member 3, and the second direction Y is perpendicular to the first direction X.

[0061] Exemplarily, in the solution of this application, the first structural member 2 is the driver's seat 2, and the second structural member 3 is the passenger seat 3. That is, the display screen sliding mechanism 1 is located between the driver's seat 2 and the passenger seat 3, and the display screen sliding mechanism 1 can make the display screen slide between the driver's seat 2 and the passenger seat 3.

[0062] It should be noted that the types of the first structural member 2 and the second structural member 3 are not specifically limited in the embodiments of this application. For example, in other possible embodiments, the first structural member 2 and the second structural member 3 can be the instrument panel and the glove box, the front pillar (A-pillar) and the rear pillar (C-pillar), the upper cross member of the front windshield frame and the upper cross member of the rear windshield frame, and so on.

[0063] Next, the display screen sliding mechanism 1 will be introduced in detail.

[0064] Refer to Figures 1 to 3, the display sliding mechanism 1 further includes a housing 10, a lead screw 20, and a sliding assembly 30. The housing 10 is in the shape of a cuboid and includes two lead screw nuts 11. The lead screw 20 is in the shape of a long rod, extends through the housing 10 along the second direction Y, and is threadedly connected to the two lead screw nuts 11. The lead screw 20 is located between the first structural member 2 and the second structural member 3. For example, the lead screw 20 can be located between the driver's seat 2 and the passenger seat 3, but the lead screw 20 is not limited to being between the driver's seat 2 and the passenger seat 3. It can also be between the instrument panel and the glove box, between the front pillar (A-pillar) and the rear pillar (C-pillar), or between the upper cross beam of the front windshield frame and the upper cross beam of the rear windshield frame.

[0065] The vehicle further includes a driving member (not shown in the figure) and a display screen (not shown in the figure). The driving member is a motor. Along the second direction Y, one end of the lead screw 20 is used to be connected to the motor, and the housing 10 is used to be connected to the display screen.

[0066] The sliding assembly 30 includes a first sliding member 31, a first sleeve 32, and a slide rail 33. The first sliding member 31 includes a connecting portion 311 and a sliding portion 312. Along the first direction X, one end of the connecting portion 311 is connected to the housing 10, and the other end of the connecting portion 311 is connected to the sliding portion 312. The first sleeve 32 is rotatably sleeved outside the connecting portion 311.

[0067] The slide rail 33 includes a chute 331 that extends along the length direction of the lead screw 20 (i.e., the second direction Y). The first sleeve 32 is confined within the chute 331 and is in rolling connection with the chute wall of the chute 331. The sliding portion 312 is slidably connected to the slide rail 33. Along the second direction Y, mounting portions 332 are respectively provided at both ends of the slide rail 33, and both ends of the lead screw 20 are respectively connected to the mounting portions 332. The two mounting portions 332 respectively correspond to the first structural member 2 and the second structural member 3.

[0068] It should be noted that the specific type of the driving member is not specifically limited in the embodiments of the present application. For example, in other possible implementation manners, the driving member can be a gear or other parts capable of driving the lead screw 20 to rotate.

[0069] It should be noted that the connection manner between the lead screw nut 11 and the housing 10 is not specifically limited in the embodiments of the present application. For example, in other possible implementation manners, the lead screw nut 11 can be connected to the housing 10 by screws, integrally formed, or welded. It should be noted that the number of the lead screw nuts 11 is not specifically limited in the embodiments of the present application. For example, in other possible implementation manners, the number of the lead screw nuts 11 can be one, three, etc. The shape of the housing 10 is not specifically limited in the embodiments of the present application. For example, in other possible implementation manners, the shape of the housing 10 can be a cube, a cylinder, etc.

[0070] With the above technical solution, when the driving member drives the lead screw 20 to rotate, through the threaded connection between the lead screw 20 and the lead screw nut 11, the circumferential rotational motion of the lead screw 20 is converted into the linear motion of the lead screw nut 11. Correspondingly, the housing 10 can also move linearly relative to the lead screw 20. The connecting portion 311 of the first sliding member 31 is connected to the housing 10, so the first sliding member 31 can be slidably connected to the slide rail 33 synchronously.

[0071] The first sleeve 32 is rotatably sleeved outside the connecting portion 311. Therefore, the first sliding member 31 drives the first sleeve 32 to move linearly relative to the lead screw 20. And during the movement, the first sleeve 32 can rotate with the first direction X as the axis. The outer wall of the first sleeve 32 contacts the groove wall of the chute 331 and generates rolling friction, thereby reducing the movement resistance. Compared with the sliding connection method between the pulley and the slide rail in the prior art, the rolling connection method in this solution can reduce the friction resistance during the operation of the display screen sliding mechanism 1, reduce the motor power, and reduce the noise.

[0072] The running track of the display screen sliding mechanism 1 refers to Figures 4a to 4c , such as Figure 3 and Figure 4a shown. In the initial state, the lead screw 20 does not rotate. At this time, the first sliding member 31 does not slide, the first sleeve 32 does not rotate, and the housing 10 is close to the installation portion 332 on the right side of the slide rail 33, that is, on the side of the co-pilot seat 3.

[0073] Such as Figure 1 , Figure 3 and Figure 4b shown. When the lead screw 20 rotates in the reverse direction, the first sliding member 31 starts to slide, and the first sleeve 32 starts to rotate. At this time, the housing 10 and the display screen can be located between the two installation portions 332, that is, at any position between the side of the driver's seat 2 and the side of the co-pilot seat 3. Any position is, for example, the position in the middle of the two installation portions 332, that is, the middle position between the driver's seat 2 and the co-pilot seat 3, but is not limited to this position. Any position can also be the position at the installation portion 332 close to the left side of the slide rail 33, that is, the position close to the side of the driver's seat 2, or the position at the installation portion 332 close to the right side of the slide rail 33, that is, the position close to the side of the co-pilot seat 3.

[0074] Such as Figure 1 , Figure 3 and Figure 4c shown. When the first sliding member 31 is close to the installation portion 332 on the left side of the slide rail 33, at this time, the housing 10 and the display screen can be close to the installation portion 332 on the left side of the slide rail 33, that is, the position on the side of the driver's seat 2.

[0075] In addition, when the lead screw 20 rotates forward, the display screen sliding mechanism 1 can drive the display screen to move from the mounting portion 332 on the left side of the slide rail 33 to the mounting portion 332 on the right side of the slide rail 33, that is, from the driver's seat 2 side to the passenger seat 3 side. During the entire operation of the display screen sliding mechanism 1, as long as the driving member stops driving, the lead screw 20 also stops rotating, the lead screw nut 11 stops moving, and correspondingly, the housing 10 also stops moving, so that the display screen also stops at the corresponding position. Therefore, the display screen sliding mechanism 1 in this solution can stop the display screen at any position between the driver's seat 2 and the passenger seat 3 according to the needs of the user.

[0076] Moreover, in this technical solution, the threaded connection between the lead screw 20 and the lead screw nut 11 can be used to realize the movement of the in-vehicle display screen between the first structural member 2 and the second structural member 3, that is, between the driver's seat 2 and the passenger seat 3, but the movement position of the in-vehicle display screen is not limited to this. For example, the in-vehicle display screen can move between the dashboard and the glove box, between the front pillar (A-pillar) and the rear pillar (C-pillar), or between the upper cross beam of the front windshield frame and the upper cross beam of the rear windshield frame. The connection between the display screen and the display screen sliding mechanism 1 is realized through the housing 10. Compared with the prior art, the connection method is simpler, reducing the part cost.

[0077] In some possible implementation manners, referring to Figure 5 and Figure 6 , the sliding assembly 30 includes a second sliding member 34, and the second sliding member 34 is in a ring shape. The second sliding member 34 is sleeved outside the first sleeve 32, and the second sliding member 34 is rotatably and slidably connected to the slide rail 33, or the second sliding member 34 is only slidably connected to the slide rail 33. Along the direction perpendicular to the length direction of the lead screw 20 (i.e., the first direction X), the second sliding member 34 is disposed on one side of the slide rail 33, and the first sliding member 31 is disposed on the opposite side of the slide rail 33.

[0078] Adopting the above technical solution, there are two connection methods between the second sliding member 34 and the slide rail 33. The first is that while the second sliding member 34 is slidably connected to the slide rail 33, the second sliding member 34 itself also rotates around the first direction X. The second is that the second sliding member 34 is only slidably connected to the slide rail 33, and the second sliding member 34 itself does not rotate. Both of these connection methods can reduce the frictional resistance during the operation of the display screen sliding mechanism 1, reduce the motor power, and reduce the noise.

[0079] It should be noted that the present application embodiment does not specifically limit the outer shape of the second sliding member 34. For example, in other possible implementation manners, the outer shape of the second sliding member 34 can be a square, a pentagon, etc., as long as the inner circle of the second sliding member 34 is circular.

[0080] In some possible embodiments, with reference to Figure 5 and Figure 6 , on the first surface 341 of the slide rail 33 where the second slider 34 acts, there are twelve first protrusions 342. The twelve first protrusions 342 are in contact with the slide rail 33, and the first protrusions 342 are arc-shaped.

[0081] Adopting the above technical solution, by the contact between the first protrusions 342 and the slide rail 33, the contact area between the second slider 34 and the slide rail 33 can be reduced, and the frictional resistance can be decreased.

[0082] It should be noted that the number of the first protrusions 342 is not specifically limited in the embodiments of the present application. For example, in other possible embodiments, the number of the first protrusions 342 can be ten, thirteen, fourteen, etc.

[0083] In some possible embodiments, with reference to Figure 5 and Figure 7 , on the second surface 3121 of the slide rail 33 where the sliding part 312 acts, there are a groove 3122 and forty-eight second protrusions 3123. One end of the first sleeve 32 is arranged in the groove 3122, and the forty-eight second protrusions 3123 are in contact with the slide rail 33. The second protrusions 3123 are hemispherical.

[0084] Adopting the above technical solution, by the contact between the second protrusions 3123 and the slide rail 33, the contact area between the sliding part 312 and the slide rail 33 can be reduced, and the frictional resistance can be decreased.

[0085] It should be noted that the number of the second protrusions 3123 is not specifically limited in the embodiments of the present application. For example, in other possible embodiments, the number of the second protrusions 3123 can be forty, fifty, fifty-six, etc.

[0086] In some possible embodiments, with reference to Figure 3 and Figure 5 , the display screen sliding mechanism 1 further includes a first connecting member 40 and a gasket part 50. The gasket part 50 includes a first gasket 51. The first gasket 51 is connected to the third surface 3124 of the sliding part 312 through the first connecting member 40, wherein the second surface 3121 and the third surface 3124 are correspondingly arranged.

[0087] The first connecting member 40 includes a first part 41 and a second part 42. The first part 41 is connected to the second part 42, and the second part 42 extends along the first direction X. The connecting part 311 is sleeved on the second part 42, and the second part 42 is riveted to the connecting part 311. The first gasket 51 is arranged between the first part 41 and the sliding part 312.

[0088] With the above technical solution, during the operation of the display screen sliding mechanism 1, due to the existence of frictional resistance, the first sliding member 31 is prone to torsion. At the same time, the first sliding member 31 is made of plastic and has poor hardness. Once the first sliding member 31 is tightly attached to other components (such as the first sleeve 32), when the first sleeve 32 rotates but the first sliding member 31 cannot rotate, the first sliding member 31 is prone to cracking due to the frictional force between the two. Therefore, a first gasket 51 is provided between the first part 41 and the sliding part 312. The material of the first gasket 51 is relatively hard, which can improve the torsional stiffness of the first sliding member 31.

[0089] It should be noted that the material of the first gasket 51 is not specifically limited in the embodiments of the present application. For example, in other possible embodiments, the material of the first gasket 51 can be aluminum alloy, aluminum parts, etc.

[0090] In some possible embodiments, referring to Figure 3 、 Figure 5 and Figure 8 , the display screen sliding mechanism 1 includes a rubber member 60. The rubber member 60 includes a first rubber part 61. The first rubber part 61 extends along the first direction X, and the first rubber part 61 is disposed between the first sleeve 32 and the connecting part 311.

[0091] With the above technical solution, in the actual production process, there are inevitably errors in the dimensions of the various components in the display screen sliding mechanism 1. By providing the first rubber part 61, the width of the first rubber part 61 can be reduced by the deformation of the first rubber part 61 under the extrusion force, so as to reserve production tolerances for the dimensions of other components (such as the connecting part 311, the first sleeve 32, etc.) during the production process, and reduce the process requirements for other components (such as the connecting part 311, the first sleeve 32, etc.).

[0092] In some possible embodiments, referring to Figure 3 、 Figure 5 and Figure 8 , the rubber member 60 includes a second rubber part 62. The gasket part 50 includes a second gasket 52. The second gasket 52 is disposed on the fourth surface 343 of the second sliding member 34. The fourth surface 343 is correspondingly arranged with the first surface 341. The second rubber part 62 is disposed between the fourth surface 343 and one end of the connecting part 311.

[0093] With the above technical solution, in the actual production process, there are inevitably errors in the dimensions of the various components in the display screen sliding mechanism 1. By providing the second rubber part 62, the height of the second rubber part 62 can be reduced by the deformation of the second rubber part 62 under the extrusion force, so as to reserve production tolerances for the dimensions of other components (such as the connecting part 311, the second sliding part 34, etc.) during the production process, and reduce the process requirements for other components (such as the connecting part 311, the second sliding part 34, etc.).

[0094] During the operation of the display screen sliding mechanism 1, when the second sliding part 34 slides along the slide rail 33, the second sliding part 34 itself also rotates axially in the first direction X, and at the same time, the first sleeve 32 also rotates axially in the first direction X. If the second sliding part 34 is closely attached to other components (such as the first sleeve 32), and the second sliding part 34 is made of plastic with poor hardness, then under the condition of rotation, the second sliding part 34 is prone to break due to the frictional force between the two. Therefore, a second gasket 52 is provided between the fourth surface 343 and one end of the connecting part 311. The second gasket 52 is made of a hard material, which can improve the torsional stiffness of the second sliding part 34.

[0095] It should be noted that the present application embodiment does not specifically limit the material of the second gasket 52. For example, in other possible implementation manners, the material of the second gasket 52 can be aluminum alloy, aluminum parts, etc.

[0096] In some possible implementation manners, referring to Figure 2 , the housing 10 includes a second connecting part 12, and the second connecting part 12 is used to connect with the display screen.

[0097] In some possible implementation manners, referring to Figure 3 and Figure 5 , the connecting part 311 includes a third part 3111, a fourth part 3112, and a fifth part 3113, and the gasket part 50 includes a third gasket 53. The third part 3111 is in a sleeve shape and extends along the first direction X. The third part 3111 is connected to the sliding part 312, and the third part 3111 is sleeved on the second part 42 of the first connecting part 40. The fourth part 3112 is in a circular ring shape, and the fifth part 3113 is in a sleeve shape and extends along the first direction X. The fourth part 3112 is connected to the fifth part 3113, and the fifth part 3113 is sleeved on the third part 3111. The third gasket 53 is provided at the riveting joint of the second part 42 and the fourth part 3112.

[0098] With the above technical solution, by providing a third gasket 53 between the second part 42 and the fourth part 3112, the contact area between the riveting joint of the second part 42 and the riveting joint of the fourth part 3112 can be increased, and the stability of the structure can be enhanced.

[0099] It should be noted that the material of the third gasket 53 is not specifically limited in the embodiments of the present application. For example, in other possible embodiments, the material of the third gasket 53 can be aluminum alloy, aluminum parts, and so on.

[0100] In some possible embodiments, referring to Figure 3 and Figure 5 , the display screen sliding mechanism 1 includes a screw part 70, and the screw part 70 includes two first screws 71. Along the first direction X, the second connecting member 12 includes two first through holes (not shown in the figure), the housing 10 includes two second through holes (not shown in the figure), and the fourth part 3112 is provided with two first threaded holes (not shown in the figure).

[0101] It should be noted that the number of the first screws 71, the first through holes, and the second through holes is not specifically limited in the embodiments of the present application. For example, in other possible embodiments, the number of the first screws 71, the first through holes, and the second through holes can be three, four, and so on respectively.
