Technical Field

[0001] This application relates to the technical field of electronic products, and particularly relates to an electronic device. Background Art

[0002] In related technologies, there are some liftable electronic products, such as, for example, a girlfriend machine. The lifting principle of existing liftable electronic products is usually that a motor drives a lead screw to rotate through a speed reducer, and the external thread of the lead screw cooperates with the internal thread of a movable rod to realize the rising or falling of the movable rod. However, this lifting method usually has problems such as a relatively slow lifting process and a long time consumption. Summary of the Invention

[0003] This application provides an electronic device, which can improve the moving speed of the electronic device body, thereby reducing the time consumption during the lifting process of the electronic device body.

[0004] In a first aspect, this application provides an electronic device, including an electronic device body and a lifting device. The lifting device includes: a fixed rod, a movable member, a driving wheel, a driven wheel, a synchronous belt, and a driving member. The driving wheel and the driven wheel are respectively rotatably connected to the fixed rod, and the driving wheel and the driven wheel are arranged at intervals along the length direction of the fixed rod. The driving wheel is in transmission connection with the driven wheel through the synchronous belt, and the driving member is connected to the driving wheel to drive the driving wheel to rotate;

[0005] The movable member is fixedly connected to the synchronous belt, and the electronic device body is fixedly connected to the movable member;

[0006] Wherein, when the driving member drives the driving wheel to rotate, the driving member drives the driven wheel to rotate through the synchronous belt, and the synchronous belt drives the electronic device body to move along the length direction of the fixed rod through the movable member.

[0007] In the embodiments of this application, by fixedly connecting the movable member to the synchronous belt and the electronic device body to the movable member, in this way, when the driving member drives the synchronous belt to move, the synchronous belt can drive the electronic device body to move along the length direction of the fixed rod through the movable member. Since the transmission efficiency of the synchronous belt is higher than that of the lead screw, therefore, in the embodiments of this application, by adopting the synchronous belt to drive the movable member to drive the electronic device body to move along the length direction of the fixed rod, the moving speed of the electronic device body can be improved, thereby reducing the time consumption during the lifting process of the electronic device body.

Obviously, the described embodiments are some, but not all, of the embodiments of the present application. All other embodiments obtained by those of ordinary skill in the art based on the embodiments in the present application belong to the scope of protection of the present application.

It should be understood that such data can be interchanged under appropriate circumstances so that the embodiments of the present application can be implemented in an order different from those illustrated or described herein, and the objects distinguished by "first", "second", etc. are usually of the same type, and the number of objects is not limited. For example, the first object can be one or more. In addition, "and / or" in the specification and claims means at least one of the connected objects, and the character " / " generally means an "or" relationship between the associated objects before and after.

[0019] Next, a lifting device and a lifting electronic device provided by the embodiments of the present application will be described in detail in conjunction with the accompanying drawings through specific embodiments and their application scenarios.

[0020] Please refer to Figures 1 to 9, An electronic device provided by an embodiment of the present application includes an electronic device body 800 and a lifting device. The lifting device includes: a fixed rod 100, a movable member 200, a driving wheel 300, a driven wheel 400, a synchronous belt 500, and a driving member 700. The driving wheel 300 and the driven wheel 400 are respectively rotatably connected to the fixed rod 100, and the driving wheel 300 and the driven wheel 400 are arranged at intervals along the length direction of the fixed rod 100. The driving wheel 300 is drivingly connected to the driven wheel 400 through the synchronous belt 500. The driving member 700 is connected to the driving wheel 300 to drive the driving wheel 300 to rotate;

[0021] The movable member 200 is fixedly connected to the synchronous belt 500, and the electronic device body 800 is fixedly connected to the movable member 200;

[0022] Wherein, when the driving member 700 drives the driving wheel 300 to rotate, the driving member 700 drives the driven wheel 400 to rotate through the synchronous belt 500, and the synchronous belt 500 drives the electronic device body 800 to move along the length direction of the fixed rod 100 through the movable member 200.

[0023] The above-mentioned electronic device can be various electronic devices with a lifting function. For example, the electronic device can be a girlfriend machine, or other lifting electronic devices similar to the girlfriend machine.

[0024] The above-mentioned fixed connection method between the movable member 200 and the synchronous belt 500 can be fixed connection by using fasteners, or alternatively, a clamping position can be set on the movable member 200, and one side of the synchronous belt 500 can be clamped into the clamping position to achieve the fixed connection between the movable member 200 and the synchronous belt 500. For example, please refer to Figure 3 , In some embodiments of the present application, the movable member 200 may include an extension block 203 extending toward one side of the fixed rod 100. The lifting device may further include a fixed block 1200. The extension block 203 and the fixed block 1200 are arranged at intervals, and a clamping position is formed between the extension block 203 and the fixed block 1200. In this way, one side of the synchronous belt 500 can be clamped into the clamping position, and the fixed block 1200, the synchronous belt 500, and the extension block 203 can be fixedly connected by fasteners. In this way, the fixed connection between the movable member 200 and the synchronous belt 500 can be achieved.

[0025] The shape of the above-mentioned movable member 200 can be set according to actual needs. For example, it can be in the shape of a rod or a plate, etc.

[0026] It is understandable that the above-mentioned lifting device may further include a base, one end of the fixed rod 100 may be fixedly connected to the base, and the driving member 700 may be disposed inside the base.

[0027] The above-mentioned driving member 700 may be various types of driving motors. Among them, the output shaft of the driving member 700 may be connected to the driving wheel 300 through a coupling to drive the driving wheel 300 to rotate forward and reverse around its own axis.

[0028] The fact that the above-mentioned driving wheel 300 is in transmission connection with the driven wheel 400 through the synchronous belt 500 means that: the synchronous belt 500 is respectively straddled in the card slots on the side surfaces of the driving wheel 300 and the driven wheel 400, and the driving wheel 300 and the driven wheel 400 tighten the synchronous belt 500.

[0029] In some embodiments of the present application, a first shaft and a second shaft may be provided on the above-mentioned fixed rod 100. The above-mentioned driving wheel 300 may be sleeved on the first shaft, and the driving wheel 300 is rotatably connected to the first shaft. The above-mentioned driven wheel 400 may be sleeved on the second shaft, and the driven wheel 400 is rotatably connected to the second shaft.

[0030] During specific implementation, the length direction of the fixed rod 100 may be set as the vertical direction, and the electronic device body 800 may be fixedly connected to the movable member 200. In this way, during the process of the driving member 700 driving the driving wheel 300 to rotate, the synchronous belt 500 can be driven to move. During the movement of the synchronous belt 500, the movable member 200 can be driven to perform a lifting movement, and further, the electronic device body 800 installed on the movable member 200 can be driven to perform a lifting movement.

[0031] Please refer to Figure 1 , in some embodiments of the present application, the electronic device body 800 may be fixedly connected to the movable member 200 through a cross bar 900. Among them, the cross bar 900 and the movable member 200 may be arranged at an angle. In Figure 1 the illustrated embodiment, the angle between the cross bar 900 and the movable member 200 is 90°. Among them, the electronic device body 800 includes a display screen, and the display screen may be used to display relevant content, and the user can also interact with the electronic device body 800 through the display screen. In addition, the electronic device body 800 can also rotate relative to the cross bar 900, so as to conveniently adjust the posture of the electronic device body 800.

[0032] In this embodiment, by fixedly connecting the movable member 200 to the synchronous belt 500 and fixedly connecting the electronic device body 800 to the movable member 200, in this way, during the process of the driving member 700 driving the synchronous belt 500 to move, the synchronous belt 500 can drive the electronic device body 800 to move along the length direction of the fixed rod 100 through the movable member 200. Since the transmission efficiency of the synchronous belt 500 is higher than that of the lead screw, therefore, in the embodiment of the present application, by adopting the synchronous belt 500 to drive the movable member 200 to drive the electronic device body 800 to move along the length direction of the fixed rod 100, the moving speed of the electronic device body 800 can be increased, thereby reducing the time consumed during the lifting process of the electronic device body 800.

[0033] Optionally, the lifting device further includes a first elastic member 600;

[0034] One end of the first elastic member 600 is fixedly connected to the movable member 200, the other end of the first elastic member 600 is fixedly connected to the fixed rod 100, and the first elastic member 600 is in an elastic deformation state. The direction of the force exerted by the first elastic member 600 on the movable member 200 is opposite to the direction of the gravity of the movable member 200, so as to reduce the force exerted by the movable member 200 on the synchronous belt 500.

[0035] The above-mentioned first elastic member 600, as a balancing component for balancing the gravity of the movable member 200 and the devices installed on the movable member 200, can adopt various types of elastic members. For example, the first elastic member 600 can be a coil spring, a gas spring or a spring, etc. Among them, the above-mentioned elastic deformation state can be an elastic stretching state or an elastic compression state. Please refer to Figure 1 , in some embodiments of the present application, when the first elastic member 600 is a coil spring, the lower end of the first elastic member 600 is fixedly connected to the movable member 200, the upper end of the first elastic member 600 is fixedly connected to the fixed rod 100, and the first elastic member 600 is in an elastic stretching state. In this way, the direction of the force exerted by the first elastic member 600 on the movable member 200 is vertically upward, while the direction of the gravity of the movable member 200 and the devices installed on it is vertically downward. Thus, the gravity of the movable member 200 and the devices installed on the movable member 200 can be balanced by the first elastic member 600, and further, the force exerted by the movable member 200 on the synchronous belt 500 can be reduced, that is, the load-bearing of the synchronous belt 500 can be reduced, so as to alleviate the problem of poor load-bearing capacity of the synchronous belt 500.

[0036] It can be understood that, in the actual implementation process, the elastic force of the first elastic member 600 can be adjusted so that the pulling force exerted by the first elastic member 600 on the movable member 200 is equal to the gravity of the movable member 200 and the equipment installed on the movable member 200. In this way, the force exerted by the movable member 200 on the synchronous belt 500 can be made to approach 0, that is, when the synchronous belt 500 drives the movable member 200 to move up and down, the synchronous belt 500 does not need to bear the weight, which is beneficial to improving the smoothness of the movement of the synchronous belt 500, and is beneficial to improving the service life of the synchronous belt 500, and further beneficial to improving the service life of the entire lifting equipment.

[0037] In addition, since the first elastic member 600 can balance the gravity of the movable member 200 and the equipment installed on the movable member 200, in this way, it is convenient to make the electronic device body 800 installed on the movable member 200 hover at different height positions, so as to facilitate the user to use the electronic device body 800 installed on the movable member 200 at different height positions.

[0038] It can be understood that the above-mentioned lifting equipment may further include a base. One end of the fixed rod 100 may be fixedly connected to the base, and the driving member 700 may be disposed inside the base. The position where the movable member 200 is fixedly connected to one end of the first elastic member 600 may be referred to as the first connection position, and the position where the movable member 200 is fixedly connected to the synchronous belt 500 may be referred to as the second connection position. In some embodiments of the present application, the first connection position may be located between the second connection position and the base.

[0039] In this embodiment, by fixedly connecting one end of the first elastic member 600 to the movable member 200, the other end of the first elastic member 600 is fixedly connected to the fixed rod 100, and the first elastic member 600 is in an elastic deformation state. The direction of the force exerted by the first elastic member 600 on the movable member 200 is opposite to the direction of the gravity of the movable member 200. In this way, since the force exerted by the first elastic member 600 on the movable member 200 and the gravity of the movable member 200 can cancel each other out, the force exerted by the movable member 200 on the synchronous belt 500 can be reduced, and further the problem of poor load-bearing capacity of the synchronous belt 500 can be overcome, which is beneficial to facilitating the installation of the electronic device body 800 that needs to be lifted on the movable member 200.

[0040] Optionally, the lifting equipment further includes a friction assembly 1100. The friction assembly 1100 is fixedly connected to the movable member 200. The friction assembly 1100 includes a friction surface 1111 that abuts against the fixed rod 100. When the synchronous belt 500 drives the movable member 200 to move, the friction assembly 1100 generates a frictional force through the friction surface 1111.

[0041] Among them, the above-mentioned friction assembly 1100 may include a friction block 1110, and the friction surface 1111 may be the end face of the friction block 1110 for fitting with the fixed rod 100. Since the friction surface 1111 of the friction assembly 1100 abuts against the fixed rod 100, there is a frictional force between the friction assembly 1100 and the fixed rod 100. And since the friction assembly 1100 is fixedly connected to the movable member 200, the frictional force between the friction assembly 1100 and the fixed rod 100 can be equivalent to the interaction force between the movable member 200 and the fixed rod 100.

[0042] It can be understood that when the movable member 200 and the fixed rod 100 are in a relatively stationary state, there is a static frictional force between the friction assembly 1100 and the fixed rod 100. By adjusting the magnitude of the pressure between the friction surface 1111 and the fixed rod 100, and adjusting the elastic force of the first elastic member 600, the elastic force of the first elastic member 600, the frictional force between the movable member 200 and the fixed rod 100, and the gravity of the movable member 200 and the devices installed on the movable member 200 are balanced, which is beneficial to conveniently realizing the hovering of the electronic device body 800 installed on the movable member 200. It can be understood that the direction of the frictional force between the friction assembly 1100 and the fixed rod 100 can be the same as or opposite to the direction of gravity.

[0043] In this embodiment, by making the lifting device further include a friction assembly 1100, the friction assembly 1100 is fixedly connected to the movable member 200, and the friction assembly 1100 includes a friction surface 1111 that abuts against the fixed rod 100. In this way, it is beneficial to conveniently realize the hovering of the electronic device body 800 installed on the movable member 200.

[0044] Optionally, the friction assembly 1100 includes a friction block 1110 and a second elastic member 1120. An installation groove is formed on the end face of the movable member 200 facing the fixed rod 100. The friction block 1110 is connected to the bottom of the installation groove through the second elastic member 1120, and the second elastic member 1120 is in an elastically compressed state. The end face of the friction block 1110 facing away from the second elastic member 1120 is the friction surface 1111, and the friction surface 1111 is located outside the installation groove.

[0045] Among them, the second elastic member 1120 may be a spring, and the second elastic member 1120 may include more than two springs. The more than two springs may be distributed at different positions between the friction block 1110 and the bottom of the installation groove. In this way, the elastic force distribution between the friction block 1110 and the bottom of the installation groove can be relatively uniform.

[0046] In some embodiments of the present application, screws can be inserted through the friction block 1110, and the friction block 1110 can be connected to the bottom of the installation groove through the screws. The friction block 1110 is spaced from the bottom of the installation groove, and the friction block 1110 can slide relative to the screws. A spring is sleeved on the screws, and both ends of the spring respectively abut between the friction block 1110 and the bottom of the installation groove.

[0047] It can be understood that the friction block 1110 can be partially embedded in the installation groove, and the friction block 1110 can slide relative to the installation groove. Among them, the cross-sectional shape and size of the friction block 1110 can match the cross-sectional shape and size of the installation groove. In this way, the side wall of the friction block 1110 can fit with the wall of the installation groove. In this way, relative movement between the friction block 1110 and the installation groove can be prevented during the movement of the movable member 200 relative to the fixed rod 100.

[0048] In this embodiment, by making the friction assembly 1100 include a friction block 1110 and a second elastic member 1120, an installation groove is provided on the end face of the movable member 200 facing the fixed rod 100. The friction block 1110 is connected to the bottom of the installation groove through the second elastic member 1120, and the second elastic member 1120 is in an elastically compressed state. The end face of the friction block 1110 facing away from the second elastic member 1120 is the friction surface 1111, and the friction surface 1111 is located outside the installation groove. In this way, the friction assembly 1100 can be equivalent to a part of the movable member 200. Correspondingly, the frictional force between the friction assembly 1100 and the fixed rod 100 can be equivalent to the frictional force between the movable member 200 and the fixed rod 100, so that a frictional force can be generated between the movable member 200 and the fixed rod 100, which is beneficial to the convenient hovering of the movable member 200 relative to the fixed rod 100. In addition, by providing a second elastic member 1120 between the friction block 1110 and the bottom of the installation groove, in this way, after the friction block 1110 is worn, due to the elastic force of the second elastic member 1120, it can be determined that the normal pressure between the friction block 1110 and the fixed rod 100 remains basically unchanged, so that the frictional force provided by the friction block 1110 is basically constant, which is further beneficial to keeping the elastic force of the first elastic member 600, the frictional force between the movable member 200 and the fixed rod 100, and the gravity of the movable member 200 and the equipment installed on the movable member 200 in balance all the time.

[0049] Optionally, the fixing rod 100 is provided with a first groove 101, and the first groove 101 extends along the length direction of the fixing rod 100. The driving wheel 300 and the driven wheel 400 are respectively arranged in the first groove 101, and the axis of the driving wheel 300 and the axis of the driven wheel 400 respectively intersect with the bottom of the first groove 101, and the movable part 200 and the driving part 700 are respectively arranged on one side of the notch of the first groove 101.

[0050] The first groove 101 is a strip-shaped groove. The axis of the driving wheel 300 and the axis of the driven wheel 400 may be perpendicular to the bottom of the first groove 101 .

[0051] It can be understood that the width of the first groove 101 is greater than the diameter of the driving wheel 300, and the width of the first groove 101 is greater than the diameter of the driven wheel 400. The driving wheel 300 and the driven wheel 400 can be completely accommodated in the first groove 101, or the driving wheel 300 and the driven wheel 400 can also be only partially accommodated in the first groove 101, that is, the driving wheel 300 and the driven wheel 400 can partially extend from the notch of the first groove 101.

[0052] In this embodiment, since the driving wheel 300 and the driven wheel 400 are respectively arranged in the first groove 101, and the driving wheel 300 is connected to the driven wheel 400 through the synchronous belt 500, the synchronous belt 500 can also be accommodated in the first groove 101, that is, the synchronous belt 500 can be embedded in the interior of the fixed rod 100, which is beneficial to reduce the space required for the lifting equipment as a whole and to achieve the miniaturization of the lifting equipment.

[0053] Optionally, the movable member 200 is rod-shaped, and the extending direction of the movable member 200 is the same as the extending direction of the fixed rod 100;

[0054] The movable member 200 defines a second groove 201 , which extends along the length direction of the movable member 200 , and the notch of the second groove 201 is opposite to the notch of the first groove 101 .

[0055] When the synchronous belt 500 is wider, at least a portion of the synchronous belt 500 can be embedded in the second groove 201 .

[0056] The extending direction of the movable member 200 is the length direction of the movable member 200, and the extending direction of the fixed rod 100 is the length direction of the fixed rod 100. It is understandable that the movable member 200 can be arranged in parallel with the fixed rod 100 so that the length directions of the two are the same.

[0057] In this embodiment, a second groove 201 is formed in the movable member 200, and the second groove 201 extends along the length direction of the movable member 200. The notch of the second groove 201 faces the notch of the first groove 101. In this way, the second groove 201 can form an avoidance groove for the synchronous belt 500, thereby avoiding interference between the movable member 200 and the synchronous belt 500, and facilitating the smooth movement of the synchronous belt 500.

[0058] Optionally, the first elastic member 600 is a spiral spring. The movable member 200 includes a mounting seat 202 extending into the annular region enclosed by the synchronous belt 500. The first elastic member 600 is mounted on the mounting seat 202. The innermost end of the first elastic member 600 is fixedly connected to the mounting seat 202, and the outermost end of the first elastic member 600 is fixedly connected to the bottom of the first groove 101.

[0059] Herein, the above-mentioned annular region is the inner region of the synchronous belt 500. Please refer to Figure 8 , in some embodiments of the present application, a part of the first elastic member 600 can be embedded in the first groove 101, and another part can be embedded in the second groove 201.

[0060] In this embodiment, by making the first elastic member 600 a spiral spring, with the innermost end of the first elastic member 600 fixedly connected to the mounting seat 202 and the outermost end of the first elastic member 600 fixedly connected to the bottom of the first groove 101, under the gravity of the movable member 200 and the electronic device body 800 mounted on the movable member 200, the first elastic member 600 can be contracted inward as a whole, so that there is a tensile force between the two ends of the first elastic member 600, and further, the direction of the force exerted by the first elastic member 600 on the movable member 200 is opposite to the direction of the gravity of the movable member 200.

[0061] Optionally, the spiral spring is a constant force spiral spring.

[0062] It can be understood that the above-mentioned first elastic member 600 is a constant force elastic member, that is, during the movement of the movable member 200 relative to the fixed rod 100, the magnitude and direction of the force exerted by the first elastic member 600 on the movable member 200 always remain unchanged. For example, in some embodiments of the present application, the spiral spring is a constant force spiral spring.

[0063] In this embodiment, since the coil spring is a constant-force coil spring, that is, when the movable member 200 moves to different height positions, the magnitude and direction of the acting force of the first elastic member 600 on the movable member 200 always remain unchanged. Thus, it is beneficial to make the elastic force of the first elastic member 600, the frictional force between the movable member 200 and the fixed rod 100, and the gravity of the movable member 200 and the devices installed on the movable member 200 always remain balanced when the movable member 200 is at different height positions, so that the electronic device body 800 installed on the movable member 200 can hover at different height positions.

[0064] Optionally, there is a gap between the first elastic member 600 and the inner wall of the synchronous belt 500.

[0065] In some embodiments of the present application, the thickness direction of the first elastic member 600 is the same as the width direction of the synchronous belt 500. To ensure that there is a gap between the first elastic member 600 and the inner wall of the synchronous belt 500, the diameter of the driving wheel 300 can be made larger than the thickness of the first elastic member 600. At the same time, the diameter of the driven wheel 400 is made larger than the thickness of the first elastic member 600, and the diameter of the driving wheel 300 is made equal to the diameter of the driven wheel 400. At this time, the distance between the two inner walls of the synchronous belt 500 is equal to the diameter of the driving wheel 300. Therefore, the distance between the two inner walls of the synchronous belt 500 can be made larger than the thickness direction of the first elastic member 600, so as to form a gap between the first elastic member 600 and the inner wall of the synchronous belt 500.

[0066] In this embodiment, by forming a gap between the first elastic member 600 and the inner wall of the synchronous belt 500, in this way, it is possible to avoid hindering the movement of the synchronous belt 500 due to the contact between the first elastic member 600 and the inner wall of the synchronous belt 500, and it is possible to avoid mutual wear between the two, which is beneficial to improving the service life of the entire lifting device.

[0067] Optionally, there is a gap between the movable member 200 and the fixed rod 100. The lifting device further includes a rolling member 1300. The rolling member 1300 is disposed at the gap between the movable member 200 and the fixed rod 100, and the movable member 200 is slidably connected to the fixed rod 100 through the rolling member 1300.

[0068] Among them, the above-mentioned rolling member 1300 can be a common rolling member 1300 such as a ball or a roller.

[0069] In some embodiments of the present application, two first sliding grooves may be formed on the end face of the fixed rod 100 facing one end of the movable member 200. The two first sliding grooves are located on both sides of the first groove 101, and the length directions of the two first sliding grooves are the same as the length direction of the fixed rod 100. At the same time, two second sliding grooves are formed on the end face of the movable member 200 facing one end of the fixed rod 100. The two second sliding grooves are located on both sides of the second groove 201, and the length directions of the two second sliding grooves are the same as the length direction of the movable rod. The two first sliding grooves correspond to the two second sliding grooves one by one, and the notch of the first sliding groove faces the notch of the corresponding second sliding groove. In this way, a plurality of rolling members 1300 can be respectively embedded between the two groups of the first sliding grooves and the second sliding grooves, and the rolling members 1300 are respectively in contact with the bottom of the corresponding first sliding groove and the bottom of the second sliding groove. In this way, during the lifting movement of the movable member 200 relative to the fixed rod 100, the rolling members 1300 can roll between the first sliding groove and the second sliding groove.

[0070] In other embodiments of the present application, only one of the above-mentioned first sliding groove and the second sliding groove may be provided, and the rolling member 1300 is rotatably installed in the sliding groove. In this way, during the lifting movement of the movable member 200 relative to the fixed rod 100, the rolling member 1300 can also roll between the movable member 200 and the fixed rod 100.

[0071] In this embodiment, by providing the rolling member 1300 at the gap between the movable member 200 and the fixed rod 100, and making the movable member 200 slidably connected to the fixed rod 100 through the rolling member 1300, the frictional resistance during the lifting movement of the movable member 200 can be reduced, and thus the smoothness of the movement of the movable member 200 during the lifting movement can be improved.

[0072] In addition, compared with the screw drive method in the related art, the lifting device provided by the embodiment of the present application has at least the following beneficial effects:

[0073] The overall machine life is improved.

[0074] The system noise problem is reduced.

[0075] The synchronous belt 500 replaces the lead screw, greatly reducing the weight and achieving the lightweight of the whole machine.

[0076] Benefiting from the improvement of the system solution, the synchronous belt 500 has high transmission efficiency and does not require special maintenance, improving the user experience.

[0077] The system cost is greatly reduced. Compared with the customized lead screw parts, the synchronous belt 500 is a standard part with low cost. At the same time, the motor power is reduced, which is convenient for the miniaturization of the equipment.

[0078] After the synchronous belt 500 is not responsible for load bearing, the speed can be greatly increased.

[0079] It should be noted that the lifting equipment provided by the embodiments of the present application can be applied not only to mobile screens, but also to other scenarios where product lifting needs to be controlled. For example, it can be applied to scenarios such as lifting desks.

[0080] The embodiments of the present application have been described above in conjunction with the accompanying drawings. However, the present application is not limited to the above specific embodiments. The above specific embodiments are merely illustrative and not restrictive. Under the inspiration of the present application, those of ordinary skill in the art can also make many forms without departing from the purpose of the present application and the scope protected by the claims, and all of them fall within the protection scope of the present application.
