[0084] Exemplary embodiments according to the present application will now be described in greater detail with reference to the accompanying drawings. These exemplary embodiments may, however, be implemented in many different forms and should not be construed as limited to the embodiments set forth herein. Rather, these exemplary embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the concept of such exemplary embodiments to those skilled in the art.

[0085] Referring to Figures 1 to 11 The present application provides a vehicle carrier, which comprises a vehicle body 100 and a clamping assembly 400.

[0086] Referring to Figure 7 In the present application, the vehicle body 100 is integrally arranged or is arranged in a relatively fixed split manner. The integrally arranged vehicle body 100 has higher structural stability. The split arranged vehicle body 100 can be split and combined according to actual needs. Understandably, whether integrally arranged or split arranged, the overall length of the vehicle body 100 remains unchanged. This consistency in length helps to ensure that the carrier can maintain a stable posture and performance when carrying the vehicle. Regardless of the size of the vehicle, the carrier can maintain a stable posture and performance, thereby ensuring the safety and efficiency of the carrying process.

[0087] The clamping assembly 400 is used to lift the wheels of the vehicle. The clamping assembly 400 is driven to act by a hydraulic drive assembly 600. Among them, two sets of clamping assemblies 400 are used to lift the front wheels and rear wheels of the vehicle, respectively. The front wheels and rear wheels of the vehicle are subjected to different forces. When lifting the front wheels and rear wheels, the clamping assembly 400 will also be subjected to different forces. The hydraulic drive assembly 600 serves as the power source for driving the clamping assembly 400 to act, and the control accuracy of the hydraulic drive assembly 600 directly affects the action strength of the clamping assembly 400. If the control accuracy of the hydraulic drive assembly 600 is insufficient, then during the carrying process, the two sets of clamping assemblies 400 may have differences in action due to the difference in driving force or action time.

[0088] In the present scheme, two hydraulic drive assemblies 600 are respectively arranged corresponding to two groups of clamping assemblies 400. That is, one hydraulic drive assembly 600 drives a group of clamping assemblies 400 to hold up the front wheels of the vehicle, and the other hydraulic drive assembly 600 drives another group of clamping assemblies 400 to hold up the rear wheels of the vehicle. By equipping each group of clamping assemblies 400 with an independent hydraulic drive assembly 600, the clamping force and action mode of each group of clamping assemblies 400 can be more accurately controlled to adapt to the different stress conditions of the front wheels and the rear wheels. Alternatively, the front wheels and the rear wheels can be held up at the same time or at different times. The vehicle handler of the present scheme can provide different time rhythms or intensities during the holding-up process. For example, it can be required to stabilize the front wheels first and then stabilize the rear wheels during the holding-up process, or to adjust the lifting order of the clamping assemblies 400 according to the position of the center of gravity of the vehicle.

[0089] In some embodiments of the present utility model, the vehicle handler further comprises a lifting device 500, which is used to drive the clamping assembly 400 to move along the height direction DH of the vehicle. Wherein, the lifting device 500 is driven to act by the hydraulic drive assembly 600.

[0090] In the present scheme, the hydraulic cylinder is used as the main power source, and the thrust is generated by the flow of hydraulic oil, so as to drive the movement of the clamping assembly 400 and the lifting device 500, thereby further adapting to different models of vehicles.

[0091] In some embodiments of the present utility model, two groups of lifting devices 500 are arranged at intervals along the width direction DW of the vehicle body 100, so as to maintain the stability and balance of the whole when lifting the vehicle. Such a layout can ensure that the vehicle does not tilt or overturn due to the shift of the center of gravity during the lifting process, thereby improving the safety of the handling process. Alternatively, the number of each group of lifting devices 500 is one or more, and the same group of lifting devices 500 is driven by the same hydraulic drive assembly 600. Exemplarily, the left lifting device 500 is driven to act by the front-end hydraulic drive assembly 600, and the right lifting device 500 is driven to act by the rear-end hydraulic drive assembly 600. Generally, the left lifting device 500 and the right lifting device 500 are lifted at the same time. Alternatively, the lifting oil cylinder is preferably a two-stage single-acting oil cylinder, which realizes a higher lifting height with a smaller installation height, and realizes a lifting of about 90mm at the highest.

[0092] Referring to Figures 7 to 8Based on the above embodiment, the vehicle body 100 includes a chassis 130 and a frame 140, with a lifting device 500 mounted between the chassis 130 and the frame 140. Specifically, the cylinder body of the lifting cylinder is fixedly connected to the top of the chassis 130, and the frame 140 is fixedly connected to the piston rod of the lifting cylinder. The clamping assembly 400 is mounted to the frame 140. Each set of lifting devices 500 includes at least three, with at least one lifting device 500 located at the front end of the vehicle body 100, at least one lifting device 500 located at the rear end of the vehicle body 100, and at least one lifting device 500 located in the middle of the vehicle body 100. This distribution helps maintain the stability and balance of the vehicle body 100 during movement. In this solution, the lifting devices 500 are arranged at the load-bearing area of ​​the vehicle body 100, namely, on the chassis 130 near the first mounting portion 210 or the second mounting portion 220, reducing the risk of structural damage caused by uneven stress distribution.

[0093] The vehicle body 100 is provided with a lifting device 500, so that the frame 140 can be movably supported on the chassis 130. Optionally, the chassis 130 adopts a monolithic welded structure. The frame 140 adopts a monolithic welded structure and can be raised and lowered along the height direction DH. The clamping assembly 400 is connected to the frame 140, allowing the clamping assembly 400 to rise and fall with the frame 140, thereby raising the entire vehicle to a certain height, ensuring that the vehicle tires are at a certain height above the ground, allowing the thin vehicle handling robot to adapt to different garage space requirements.

[0094] In some embodiments, along the length direction DL, the front end of the frame 140 is provided with a first mounting portion 210, and the rear end of the frame 140 is provided with a second mounting portion 220. The first mounting portion 210 and the second mounting portion 220 are provided for mounting the clamping assembly 400.

[0095] Optionally, a detachable cover 150 is connected to the top of the vehicle body 100. The cover 150 is bolted to the vehicle body 100 to enclose the first mounting portion 210, the second mounting portion 220, and the clamping assembly 400 to prevent dust from entering. Optionally, the cover 150 is fixedly mounted to the top of the frame 140 and can be raised and lowered as the frame 140 is raised and lowered.

[0096] By way of example, there are eight lifting devices 500. Four of the lifting devices 500 are arranged diagonally and located on the chassis 130 near the four corners of the first mounting portion 210. Four of the lifting devices 500 are arranged diagonally and located on the chassis 130 near the four corners of the second mounting portion 220. Because the second mounting portion 220 can move relative to the chassis 130 along the slide rail 110, the four lifting devices 500 are specifically arranged on the chassis 130 near the four corners of the slide rail 110. The lifting devices 500 provide more stable support for the frame 140.

[0097] Referring to Figure 4 , the following describes a specific clamping assembly 400.

[0098] The clamping assembly 400 includes two pairs of clamping arms 410, which are spaced apart and symmetrically arranged along the width direction DW of the vehicle body 100, and each pair of clamping arms 410 includes two clamping arms 410 that can form a clamping space for holding a vehicle wheel. By optimizing the arrangement of the clamping assembly 400, the vehicle wheel can be clamped and released, thereby shortening the time of the entire carrying process and improving the carrying efficiency.

[0099] The clamping arm 410 includes an opposite hinge end and a free end, and the hinge end is hingedly connected to the first mounting portion 210 or the second mounting portion 220. The hinge end of the clamping arm 410 is provided with a gear 411, and the rotation center of the gear 411 coincides with the rotation center of the clamping arm 410. Through the arrangement of the gear 411, the precise control and coordinated movement of the clamping arm 410 can be achieved.

[0100] The rotation directions of the two clamping arms 410 in each pair are opposite. That is, the two clamping arms 410 can be relatively close, that is, the two clamping arms 410 are simultaneously moved to the middle position to form a clamping to the vehicle wheel; the two clamping arms 410 can be relatively far away, that is, the two clamping arms 410 are simultaneously moved to the direction close to the vehicle body 100 to release the vehicle wheel. When the two clamping arms 410 are in the clamping state, the free end of the clamping arm 410 is suspended.

[0101] The clamping assembly 400 further includes a second driving member 420 for driving the two clamping arms 410 in each pair to rotate synchronously.

[0102] Optionally, the two clamping arms 410 in each pair are respectively connected to a transmission member 430 through the respective gears 411, and the transmission member 430 is driven to act by the second driving member 420. That is, the transmission member 430 is meshingly connected with the gears 411 of the two clamping arms 410 in each pair.

[0103] Optionally, the two clamping arms 410 in each pair are meshingly connected with each other through the respective gears 411, and the second driving member 420 is connected to one of the clamping arms 410 or the gears 411 through the transmission member 430.

[0104] The above two transmission modes can ensure the synchronism and stability of the two clamping arms 410 in the rotation process through the meshing transmission of the gears 411. Through the precise control of the second driving member 420, the synchronous action of the clamping arms 410 is controlled to achieve a stable clamping effect.

[0105] On the basis of the above embodiment, the second driving member 420 is one of a worm gear mechanism, a linear motor mechanism, and a pneumatic / hydraulic linear module.

[0106] Exemplarily, the second driving member 420 is a worm gear mechanism. The second driving member 420 is a motor, and the transmission member 430 is a worm. The worm is connected to the output end of the motor. The worm gear is coaxially arranged at the hinged end of the clamping arm 410. The worm and the worm gear are engaged, that is, the motor drives the worm to rotate, the worm rotates to drive the worm gear to rotate, thereby driving the clamping arm 410 to rotate around the hinged axis, so as to realize the relative approaching or moving away of the clamping arm 410. Optionally, each pair of two clamping arms 410 corresponds to a worm respectively, and the rotation directions of the two worms are opposite. The two worms are engaged with the same worm respectively, so that a group of motors simultaneously drive two groups of worm gears to rotate, thereby driving two clamping arms 410 to rotate in opposite directions synchronously, so as to realize the opening or folding of the clamping arm 410 mechanism. The worm gear mechanism has a self-locking effect, which can avoid the self-folding of the clamping arm 410 without external force when the clamping arm 410 is opened, thereby ensuring the safety of the vehicle carrier.

[0107] Exemplarily, the second driving member 420 is a hydraulic linear module. The second driving member 420 is a hydraulic cylinder, and the transmission member 430 is a connecting rod. The connecting rod is hingedly connected to the output end of the hydraulic cylinder and one of the clamping arms 410 or the gear 411 respectively. In this scheme, the connecting rod is hingedly connected to the output end of the hydraulic cylinder and one of the clamping arms 410 respectively. Specifically, one end of the clamping arm 410 close to the hinged end is connected with the transmission rod. The hydraulic cylinder is connected to the middle part of the transmission rod. The hydraulic cylinder drives the transmission rod to rotate, thereby driving one clamping arm 410 to rotate around the hinged end of the clamping arm 410. The two clamping arms 410 are driven by the gear 411 to mesh and transmit, thereby realizing the opening or folding of the clamping arm 410. In this scheme, the gear 411 is coaxially arranged at the hinged end of the clamping arm 410, and the transmission ratio of the meshed gears 411 is 1.

[0108] In some embodiments of the utility model, a plurality of rotating bodies 440 are arranged between the hinged end and the free end of the clamping arm 410. The plurality of rotating bodies 440 are coaxially arranged. When clamping, the rotating bodies 440 contact the vehicle tire to reduce the friction between the tire and the clamping arm 410, thereby avoiding damage to the tire. The types of the rotating bodies 440 include but are not limited to long rollers and bearings.

[0109] In some embodiments of the utility model, the free end of the clamping arm 410 is provided with a supporting wheel 450, and the rotation axis of the rotating body 440 is coaxially arranged with the rotation axis of the supporting wheel 450.

[0110] On the basis of the above-mentioned embodiments, the side of the vehicle body 100 is provided with a receiving groove 141, and the clamping assembly 400 can be received in the receiving groove 141, and in the state that the clamping assembly 400 is received in the receiving groove 141, the supporting wheel 450 is supported into the receiving groove 141. Alternatively, the side frame 140 of the vehicle body 100 can directly adopt a channel steel or the like profile, and the slotting of the channel steel forms the receiving groove 141. When the clamping arm 410 is retracted, the clamping arm 410 is received.

[0111] On the basis of the above-mentioned embodiments, the diameter of the supporting wheel 450 is greater than the diameter of the rotating body 440. When the clamping arm 410 is received into the receiving groove 141, the supporting wheel 450 can slide into the receiving groove 141 and be supported in the receiving groove 141.

[0112] On the basis of the above-mentioned embodiments, the second driving member 420 adopts a hydraulic cylinder. The vehicle carrier further comprises a hydraulic driving assembly 600. That is, the clamping assembly 400 is driven to act by the hydraulic driving assembly 600. As mentioned above, two sets of clamping assemblies 400 are respectively used to hold the front wheels and the rear wheels of the vehicle. In this scheme, two hydraulic driving assemblies 600 are respectively arranged corresponding to the two sets of clamping assemblies 400. That is, one hydraulic driving assembly 600 drives one set of clamping assemblies 400 to hold the front wheels of the vehicle, and the other hydraulic driving assembly 600 drives the other set of clamping assemblies 400 to hold the rear wheels of the vehicle. By equipping each set of clamping assemblies 400 with an independent hydraulic driving assembly 600, the clamping force and the action mode of each set of clamping assemblies 400 can be more accurately controlled to adapt to the different stress conditions of the front wheels and the rear wheels. Alternatively, the front wheels and the rear wheels can be held at the same time or at different times. The vehicle carrier of this scheme can provide different time rhythms or intensities in the holding process. For example, it can be necessary to stabilize the front wheels before stabilizing the rear wheels in the holding process, or to adjust the lifting order of the clamping assemblies 400 according to the position of the center of gravity of the vehicle. Alternatively, the hydraulic driving assemblies 600 are respectively located at the front end and the rear end of the vehicle body 100. The clamping assembly 400 connected to the first mounting portion 210 is driven to act by the hydraulic driving assembly 600 at the front end, and the clamping assembly 400 connected to the second mounting portion 220 is driven to act by the hydraulic driving assembly 600 at the rear end.

[0113] As mentioned above, the clamping assembly 400 and the lifting device 500 can be powered by the hydraulic driving assembly 600.

[0114] Reference Figures 2 to 3The hydraulic driving assembly 600 comprises an oil tank 610 and a hydraulic pump 620. The oil tank 610 and the hydraulic pump 620 are connected by a pipeline 650. The pipeline 650 is responsible for delivering hydraulic oil in the oil tank 610 to the hydraulic cylinders to generate the required driving force. Two pipelines 650 are arranged at the outlet of the hydraulic pump 620, one for supplying oil to the hydraulic cylinders of the clamping assembly 400, and the other for supplying oil to the hydraulic cylinders of the lifting device 500. The hydraulic cylinders of the clamping assembly 400 and the hydraulic cylinders of the lifting device 500 realize the extension and retraction movement according to the flow and pressure change of the hydraulic oil.

[0115] On the basis of the above embodiment, the pipeline 650 is provided with a control valve 630. The control valve 630 adjusts the flow and pressure of the hydraulic oil. The types of the control valve 630 include but are not limited to solenoid valve, throttle valve, and reversing valve. Two control valves 630 are respectively arranged corresponding to two groups of clamping assemblies 400. Alternatively, the hydraulic cylinders of the two pairs of clamping arms 410 of the same group of clamping assemblies 400 are controlled by the same control valve 630, to ensure the synchronization of the same group of clamping assemblies 400.

[0116] On the basis of the above embodiment, the pipeline 650 is provided with a balance valve 640. Alternatively, the balance valve 640 is arranged between the control valve 630 and the hydraulic cylinders of the same group of clamping assemblies 400. The control valve 630 uniformly distributes the oil flow of the hydraulic cylinders of the same group of clamping assemblies 400, balances the driving force of the two pairs of clamping arms 410, and makes the clamping force of the two pairs of clamping arms 410 the same.

[0117] The vehicle carrier comprises a plurality of walking devices 700, which are fixedly installed to the vehicle body 100 and are used to drive the omnidirectional movement of the vehicle body 100. Specifically, the walking device 700 is connected to the lower end of the chassis 130.

[0118] The above-mentioned walking device 700 can be provided with only a driving wheel mechanism, or can adopt a structure in which a driving wheel mechanism and a universal wheel mechanism are matched. Among them, the driving wheel mechanism can be at least one of a differential wheel mechanism, a rudder wheel mechanism or a Mecanum wheel mechanism.

[0119] The following will be specifically described taking the differential wheel mechanism as an example.

[0120] The walking device 700 comprises two walking wheels 710, each of which can be independently driven, and the rotation axes of the two walking wheels 710 are parallel or coincident. During walking, the balance steering or driving of the vehicle body 100 can be realized by independent control of each walking wheel 710, such as controlling the two walking wheels 710 to adopt different speeds, so that the vehicle body 100 can be balanced to steer, realize the avoidance, warehousing or meet other driving path requirements.

[0121] On the basis of the above-mentioned embodiments, the walking wheel 710 is driven to rotate by the third driving member 720. Optionally, the third driving member 720 is a speed reducer motor. The walking wheel 710 is connected to the output end of the speed reducer motor.

[0122] The at least two groups of walking devices 700 are arranged at intervals along the width direction DW of the vehicle body 100, ensuring the stability of the vehicle body 100 in the transverse direction, preventing the vehicle body 100 from overturning or tilting when driving. The number of each group of walking devices 700 is at least three, wherein at least one walking device 700 is located at the end of the first mounting portion 210 away from the second mounting portion 220, and at least one walking device 700 is located at the end of the second mounting portion 220 away from the first mounting portion 210. That is, the walking devices 700 are arranged at the front end and the rear end of the vehicle body 100, so that the vehicle body 100 is more flexible and stable when turning or adjusting the driving direction, and the precise control of the vehicle body 100 can be realized by adjusting the speed and direction of the walking devices 700 at different positions. At least one walking device 700 is located at the end of the first mounting portion 210 close to the second mounting portion 220, and the walking device 700 located in the middle position plays the role of connecting and supporting the two groups of walking devices 700, thereby enhancing the overall structural strength of the vehicle body 100. By arranging a plurality of walking devices 700, the weight of the vehicle body 100 is effectively dispersed, and the load-bearing capacity is enhanced, so that the vehicle body 100 can carry a larger load, and the precise control and flexible turning of the vehicle body 100 can be realized by separately operating the walking devices 700, thereby improving the adaptability and passability of the vehicle body 100.

[0123] In some embodiments of the present application, the first mounting portion 210 and the second mounting portion 220 are both provided with detection mechanisms. The detection mechanism is used to detect the vehicle tire. Illustratively, when the detection mechanism of the first mounting portion 210 detects the front tire of the vehicle, a signal is sent, and the vehicle carrier stops moving forward; at this time, the second mounting portion 220 slides along the slide rail 110 of the vehicle body 100, and when the detection mechanism on the second mounting portion 220 detects the rear tire of the vehicle, a signal is sent, and the second mounting portion 220 stops sliding. The detection mechanism can be a proximity switch.

[0124] The adaptability adjustment of the vehicle carrier to vehicle bodies of different lengths is described below.

[0125] In some embodiments of the utility model, the vehicle body 100 includes a slide rail 110 extending along the length direction DL of the vehicle body 100. The slide rail 110 enables the clamping assembly 400 to be quickly and accurately positioned to the appropriate position of the vehicle, ensuring that the vehicle carrier maintains a stable posture when carrying vehicles of different sizes, avoiding shaking or tilting due to the mismatch of vehicle size, and improving the carrying efficiency. The setting of the slide rail 110 enhances the adaptability and flexibility of the vehicle carrier, enabling it to carry vehicles of different sizes. It should be noted that the overall length of the vehicle body 100 is greater than the wheelbase between the front wheels and the rear wheels of the clamped vehicle. Therefore, the spacing between the two groups of clamping assemblies 400 can be adapted to the wheelbase of the vehicle.

[0126] Although this vehicle carrier with a slide rail 110 and a movable mounting portion solves the problems of the conventional carrying method to some extent, when the clamping assembly 400 is slidingly connected to the slide rail 110, the connection strength between the clamping assembly 400 and the vehicle body 100 is insufficient, causing the clamping assembly 400 to shake or tilt during the carrying process, thereby affecting the stability and safety of the carrier, and easily causing accidental falling or sliding, which brings great safety hazards to the operator and the surrounding environment.

[0127] In this scheme, the clamping assembly 400 is provided in two groups. The two groups of clamping assemblies 400 are respectively mounted to the first mounting portion 210 and the second mounting portion 220.

[0128] The first mounting portion 210 is fixedly mounted to the vehicle body 100. Optionally, the first mounting portion 210 is integrally formed with the vehicle body 100. When the clamping assembly 400 is mounted to the first mounting portion 210, the relative position of the clamping assembly 400 to the vehicle body 100 does not change along the length direction DL of the vehicle body 100.

[0129] The second mounting portion 220 is movably mounted to the slide rail 110 along the length direction DL. When the clamping assembly 400 is mounted to the second mounting portion 220, the clamping assembly 400 can move along the length direction DL of the vehicle body 100, thereby changing the relative spacing between the two groups of clamping assemblies 400. The relative spacing between the two groups of clamping assemblies 400 can be adjusted according to the size of the vehicle.

[0130] Referring to Figure 9 In this scheme, the second mounting portion 220 further includes a side sliding pulley 221 located on the side of the slide rail 110. The second mounting portion 220 is slidingly connected to the slide rail 110 through the side sliding pulley.

[0131] When the clamping assembly 400 is slidingly connected to the slide rail 110, only the connection between the slide rail 110 and the second mounting portion 220 may result in insufficient connection strength, thereby causing shaking or tilting during the carrying process.

[0132] A limit rail 120 is provided on the side of the slide rail 110, and the limit rail 120 extends in the same direction as the slide rail 110. The limit rail 120 and the slide rail 110 together define the moving track of the side shift pulley to prevent the side shift pulley from deflecting or deviating from the predetermined track during movement.

[0133] The limiting guide rail 120 is located above the side sliding wheel 221, and at least a portion of the projection of the limiting guide rail 120 along the height direction DH of the vehicle body 100 overlaps with the projection of the side sliding wheel 221. The side sliding wheel 221 and the limiting guide rail 120 provide additional support and guidance, strengthening the connection between the second mounting portion 220 and the vehicle body 100, thereby preventing the carrier from accidentally falling off during use. Furthermore, the coordinated arrangement of the side sliding wheel 221, the slide rail 110, and the limiting guide rail 120 reduces wear and damage to the second mounting portion 220 during movement.

[0134] In some embodiments of the present invention, there are one or more slide rails 110 . When there are multiple slide rails 110 , the multiple slide rails 110 are spaced apart along the width direction DW of the vehicle body 100 .

[0135] In some embodiments of the present invention, two sets of side sliding wheels 221 are provided along the width direction DW of the vehicle body 100. The two sets of side sliding wheels 221 are respectively located on the outer sides of the slide rails 110, which can form a more stable support structure.

[0136] In some embodiments of the present invention, the second mounting portion 220 further includes an upper sliding wheel 222 located above the slide rail 110. The provision of the upper sliding wheel 222 enhances the fit between the second mounting portion 220 and the slide rail 110, thereby further reducing wear and damage to the second mounting portion 220 during movement.

[0137] Based on the above embodiment, there is only one slide rail 110, two sets of side sliding wheels 221 are located on either side of the slide rail 110, and two position-limiting guide rails 120 are located on either side of the slide rail 110. When there are multiple slide rails 110, the two sets of side sliding wheels 221 are located outside the outermost slide rail 110, and the two position-limiting guide rails 120 are located outside the outermost slide rail 110. It will be understood that the two sets of side sliding wheels 221 are symmetrically arranged. The two position-limiting guide rails 120 are symmetrically arranged. Optionally, after the second mounting portion 220 is mounted to the slide rail 110, the position-limiting guide rails 120 are fastened to the slide rail 110 via fasteners.

[0138] Through the above solution, the force applied to the second mounting portion 220 is symmetrical and balanced, which helps to prevent accidents such as shaking, tilting or falling off during movement and use, thereby enhancing the safety of the carrier.

[0139] In some embodiments of the utility model, the second mounting part 220 is provided with a linear drive module 300, and the linear drive module 300 is used to drive the second mounting part 220 to move along the slide rail 110.

[0146] The screw rod 310 has the same extension direction as the slide rail 110. In some embodiments, the slide rail 110 is provided in multiple numbers, and the screw rod 310 is located between adjacent slide rails 110. This layout can effectively utilize space and reduce the size of the vehicle carrier.

[0147] The first driving member 320 is used for driving the screw rod 310 to rotate. Optionally, the type of the first driving member 320 includes but is not limited to a stepper motor and a servo motor.

Specifically, the output end of the first driving member 320 is connected with a first gear 371, and the end of the screw rod 310 is connected with a second gear 372. The first gear 371 is engaged with the second gear 372. That is, the first gear 371 and the second gear 372 are driven to rotate by the first driving member 320, thereby driving the screw rod 310 to rotate and finally driving the second mounting portion 220 to linearly slide along the slide rail 110.
