[0040] Figure 1 This is a schematic diagram of the structure of the battery replacement parking equipment. Figure 1 As shown, the battery swap parking equipment includes a frame 10 and a pair of the vehicle position adjustment devices. Two sets of vehicle position adjustment devices are respectively connected to the frame 10, and are respectively located substantially at positions corresponding to the front wheels and rear wheels of the vehicle, one of which is used to move the front wheels of the vehicle, and the other vehicle position adjustment device is used to move the rear wheels of the vehicle. When working, the vehicle position adjustment device corrects the posture of the vehicle by adjusting the position of the front wheels and the rear wheels in the horizontal plane to achieve centering operation; in addition, the two sets of vehicle position adjustment devices simultaneously lift the front wheels and the rear wheels of the vehicle to achieve position adjustment in the height direction of the vehicle, so that the battery swap trolley can replace the battery box for the vehicle. In some other embodiments, after the vehicle is lifted to a suitable height, the vehicle transporter can also be moved to the bottom of the vehicle to carry the vehicle to realize the vehicle transport function. Those skilled in the art can set the application scenario of the battery swap parking equipment according to actual needs, for example, it can be used for battery swap or three-dimensional parking system.

[0041] Figure 2 It is a schematic diagram of the structure of the vehicle position adjustment device. Figure 2As shown, the vehicle position adjustment device includes a lifting mechanism and a clamping wheel mechanism 40. The lifting mechanism is used to adjust the height position of the vehicle in the vertical direction; the clamping wheel mechanism 40 is used to adjust the position of the vehicle in the horizontal direction, that is, to adjust the parking angle of the vehicle so that the vehicle is parked in a preset direction.

[0042] Figure 3 It is a structural diagram of the lifting mechanism. Figure 2 and Figure 3 As shown, the lifting mechanism includes a lifting platform 20 and a lifting drive assembly 30. The lifting platform 20 is used to carry the wheels of the vehicle, and the lifting drive assembly 30 is used to pull the lifting platform 20 to move upward or downward in the vertical direction.

[0043] The lifting platform 20 is generally in the form of a flat plate, and a cavity 21 for accommodating a clamping rod mechanism is provided in the middle. Both ends of the lifting platform 20 are arranged to move in the vertical direction. Specifically, a lifting seat 22 is connected to each of the two ends of the lifting platform 20, and the lifting seat 22 can be fixedly connected to the end of the lifting platform 20 by welding or a connecting piece. As an example, one or more slides 221 are provided on the side of the lifting seat 22 relative to the lifting platform 20. Correspondingly, the frame 10 is provided with a slide rail 222 extending along the setting direction, and the slide 221 is slidably connected to the slide rail 222, and the lifting seat 22 can be moved in the vertical direction through the slide 211 and the slide rail 222.

[0044] Figure 4 3 is a schematic diagram of the structure of the lifting drive assembly 30. Figure 2 and Figure 4 As shown, the lifting drive assembly 30 includes a driving component and a pair of transmission components. The driving member 44 can pull the lifting platform 20 to move in the vertical direction through a pair of transmission components. Specifically, in this embodiment, the driving component includes a lifting motor 31 and a synchronization shaft 32. The lifting motor 31 is located at the top of the bracket and is used to drive the synchronization shaft 32 to rotate. The length of the synchronization shaft 32 is roughly equivalent to the width of the bracket, and both ends are rotatably connected to the top of the bracket. The two ends of the bracket are respectively connected to a transmission assembly, which is used to pull the two ends of the lifting platform 20 to rise or fall at the same time through the transmission assembly, thereby improving the stability of the lifting and lowering movement of the lifting platform 20.

[0045] As an example, the transmission assembly includes a sprocket 34 and a chain 33. The sprockets 34 of the two transmission assemblies are connected to the ends of the synchronization shaft 32, that is, the two ends of the synchronization shaft 32 are each connected to a sprocket 34 of a transmission assembly. At the same time, the bottom position of the bracket is also connected to a sprocket 34 of a transmission assembly. The chain 33 of each transmission assembly is an annular circulating chain, and the chain 33 bypasses the sprocket 34. In this way, the lifting motor 31 can synchronously drive the sprockets 34 of the two transmission assemblies to rotate at the same speed and in the same direction through the synchronization shaft 32. In each transmission assembly, the top sprocket 34 rotates to drive the chain 33 to rotate in a circular manner. In some embodiments, the chain 33 can also be connected in series with one or more tensioning members 331 to adjust the tensioning degree of the chain 33.

[0046] In addition, the lifting seat 22 is fixedly connected to the chain 33 through the connecting plate 223, so that during the circular movement of the chain 33, the lifting seat 22 can be pulled to move in the vertical direction through the connecting plate 223. During operation, the lifting motor 31 drives the chains 33 of the two transmission components to move synchronously and at the same speed through the synchronous shaft 32, and the chains 33 of the two transmission components drive the two ends of the lifting platform 20 to move synchronously and at the same speed through the lifting seat 22, so that the lifting platform 20 can move smoothly in the vertical direction, thereby preventing the lifting platform 20 from tilting during the lifting process.

[0047] Figure 5 Schematic diagram of the structure of the clamping wheel mechanism 40. Figure 5 As shown, the wheel clamping mechanism 40 includes a base 41, a wheel clamping rod 42, a wheel clamping drive assembly and a sensor 47. The base 41 is used to carry other components of the wheel clamping mechanism 40, and is used to correspond to the size of the cavity 21 of the lifting platform 20, so that the entire wheel clamping mechanism 40 can be installed on the lifting platform 20 as a whole, improving the convenience of production for the installation of the wheel clamping mechanism 40 and realizing modular assembly. The wheel clamping rod 42 is used to move along the width direction of the vehicle to push the wheel of the vehicle, the wheel clamping drive assembly is used to drive the wheel clamping rod 42 to move along the width direction of the vehicle, and the sensor 47 is used to trigger when the deformation of the elastic member 46 exceeds a preset value.

[0048] Figure 6 It is a schematic diagram of the structure of the clamping wheel drive assembly. Figure 5 and Figure 6 As shown, the clamping wheel driving assembly includes a driving member 44, an elastic member 46, a transmission member and a moving seat 45. The driving member 44 can be a motor or other forms of power devices. In this embodiment, the driving member 44 is fixed to the middle of the base 41.

[0049] The transmission member is connected to the driving member 44 for transmission, and drives the clamping wheel rod 42 to move through the elastic member 46. In this embodiment, the transmission member includes a screw 441 and a nut 443, wherein the screw 441 is connected to the driving member 44, and the nut 443 is threadedly connected to the screw 441. Specifically, both ends of the screw 441 are rotatably connected to the base 41 through two supports 446, and one end is connected to the driving member 44 through a coupling 442. The driving member 44 can drive the screw 441 to rotate through the coupling 442. The nut 443 is sleeved on the screw 441 and is threadedly connected to the screw 441. When the screw 441 rotates, the nut 443 can move along the length direction of the screw 441.

[0050] In order to prevent the screw rod 441 from driving the nut 443 to rotate during the rotation process, and to transmit the power through the movement of the nut 443, in this embodiment, the clamping rod mechanism may further include a moving seat 45. The two ends of the moving seat 45 along the width direction of the base 41 are movably connected to the base 41 through a slider-rail structure. The middle part of the moving seat 45 is connected to the nut 443 and the spring, so as to realize the movement along the length direction of the base 41 under the traction of the nut 443, that is, the movement back and forth in the width direction of the vehicle.

[0051] Figure 7 Schematic diagram of the structure of the moving seat 45 and the transmission member. Figure 6 and Figure 7 As shown, the middle part of the movable seat 45 has an open cavity, and the nut 443 is embedded in the cavity, and the nut 443 and the movable seat 45 are installed together. The nut 443 includes a first clamping portion 444, and the two ends of the first clamping portion 444 are located on the side walls of the cavity. At the same time, the movable seat 45 has a through hole, and the nut 443 passes through the through hole, so that the nut 443 can move back and forth relative to the movable seat 45 along the width direction of the vehicle. During the movement, the first clamping portion 444 moves along the side wall of the cavity to play a guiding role. Correspondingly, the movable seat 45 includes a second clamping portion 445, and the second clamping portion 445 is located at the end of the movable seat 45, which is used to stop the first clamping portion 444. When the nut 443 moves to the end position of the movable seat 45, the first clamping portion 444 abuts the second clamping portion 445, driving the movable seat 45 to move.

[0052] In addition, the elastic member 46 is provided between the driving member 44 and the wheel clamping rod 42, and the driving member 44 pushes the wheel clamping rod 42 to move through the elastic member 46. Specifically, the elastic member 46 can be a spring, which is located between the nut 443 and the movable seat 45, and is used to push the movable seat 45 through the elastic member 46. In this embodiment, the elastic member 46 is sleeved on the nut 443, and one end abuts against the first clamping portion 444, and the other end abuts against the movable seat 45. When the nut 443 moves toward a direction close to the wheel, the nut 443 squeezes the elastic member 46 through the first clamping portion 444, the elastic member 46 generates elastic deformation, and pushes the movable seat 45 to move in a direction close to the wheel along the width direction of the vehicle. When the nut 443 moves in a direction away from the wheel (i.e., moves in the reverse direction), the elastic member 46 is released during the reverse movement of the nut 443; when the nut 443 moves to the point where the first engaging portion 444 abuts against the second engaging portion 445, the nut 443 engages the second engaging portion 445 via the first engaging portion 444 to drive the moving seat 45 to move in a direction away from the wheel.

[0053] Please review Figure 5 The clamping wheel driving assembly also includes a pair of transmission wheels 431 and an annular transmission belt 43, and the mobile seat 45 pulls the clamping wheel rods 42 on both sides to move closer to or away from each other through the transmission belt 43. Specifically, the transmission belt 43 and the transmission wheel 431 include two groups, and the mobile seat 45 is provided with a group of transmission belts 43 and transmission wheels 431 on both sides along the width direction of the base 41, which are used to pull the two ends of the clamping wheel rod 42 at the same time. In each group of transmission belts 43 and transmission wheels 431, the number of transmission wheels 431 is two, and they are arranged at the two ends of the base 41 along the length direction of the base 41. The transmission belt 43 is a circulating belt, which bypasses the transmission wheel 431 and can be circulated back and forth along the length direction of the base 41 through the transmission wheel 431. In this embodiment, the two ends of the mobile seat 45 are respectively connected to the transmission belt 43, so that the transmission belt 43 can be driven to move back and forth. It is understood by those skilled in the art that the transmission belt 43 can be a chain, a synchronous belt or other components, and correspondingly, the transmission wheel 431 can also be a sprocket or a synchronous wheel or other components.

[0054] Figure 8 4 is a schematic diagram of the structure of the clamping wheel rod 42. Figure 5 and Figure 8 As shown, the wheel clamping rod 42 is movably connected to the lifting platform 20 along the width direction of the vehicle, so that when the wheel moves to the lifting platform 20, the driving member 44 pushes the wheel clamping rod 42 through the elastic member 46 to push the wheel.

[0055] The wheel clamping mechanism 40 includes a pair of wheel clamping rods 42, which are respectively located at the two ends of the length direction of the base 41, so that the two front wheels or the two rear wheels of the vehicle can be clamped from the width direction of the vehicle at the same time to achieve the function of correcting the position of the vehicle. Specifically, the wheel clamping mechanism 40 also includes two moving plates 421, and each end of each wheel clamping rod 42 is connected to a moving plate 421, which is used to pull the two ends of the wheel clamping rod 42 through the moving plate 421 to move the wheel clamping rod 42. The moving plate 421 is provided with a rolling groove 422 extending along the length direction of the base 41; correspondingly, the base 41 is provided with a plurality of rotatably connected rollers 423, and the rollers 423 are embedded in the rolling grooves 422, so that the moving plate 421 can be moved along the length direction of the base 41 through the rollers 423.

[0056] Please review Figure 5 and Figure 8 , the other end of the moving plate 421 relative to the clamping wheel rod 42 is also connected to the transmission belt 43 through the connecting block 432, and at the same time, the moving plate 421 is also connected to the moving seat 45 at one end through the connecting plate. Therefore, the connecting block 432 is connected to the moving seat 45 and the moving plate 421 at the same time, and is also connected to the transmission belt 43. In this way, the connecting block 432, the moving seat 45, the moving plate 421 and the transmission belt 43 are connected to each other and can move simultaneously during the moving process. During operation, the moving seat 45 drives the two moving plates 421 at one end to move, and drives the transmission belt 43 to move at the same time; the transmission belt 43 drives the moving plate 421 at the other end to move through the connecting block 432, so that the clamping wheel rods 42 at both ends are simultaneously approached or moved away.

[0057] In addition, in order to facilitate the movement of the wheel on the base 41, the wheel clamping mechanism 40 also includes a roller 424, which extends along the length direction of the vehicle or is inclined to the width direction of the vehicle, and is used to carry the wheel of the vehicle. The rollers 424 can be multiple groups, which can extend along the length direction of the vehicle or be inclined to the width direction of the vehicle to form a "V" shape layout, which can reduce the friction force on the wheel during movement, thereby reducing wheel wear and protecting the wheel.

[0058] Please review Figure 5 and Figure 7 , the sensor 47 can be a photoelectric switch, or a detection device such as a magnetic induction switch. As an example, the sensor 47 is a magnetic induction switch, which is fixedly connected to the moving seat 45, so that it can move with the moving seat 45. Correspondingly, the first engaging portion 444 is also provided with a sensing sheet, which is used to be sensed by the sensor 47 when following the nut 443 to move to the corresponding position. The sensor 47 is configured to follow the nut 443 to move to the position of triggering the sensor 47 when the distance between the nut 443 and the moving seat 45 exceeds a preset value.

[0059] The working process of the above-mentioned wheel clamping mechanism 40, vehicle position adjustment device and battery replacement parking device is described in detail below.

[0060] When the front wheels and rear wheels of the vehicle are parked at the two vehicle position adjustment devices respectively, the two wheel clamping mechanisms 40 adjust the horizontal posture of the vehicle.

[0061] First, the driving member 44 drives the screw rod 441 to rotate, and drives the moving seat 45 to move through the nut 443. At this time, the first engaging portion 444 follows the nut 443 to move in the direction close to the wheel, pushing the elastic member 46. The elastic member 46 is deformed and pushes the moving seat 45 to move. On the one hand, the moving seat 45 drives the wheel clamping rod 42 at one end to move through the connecting block 432 and the moving plate 421, and on the other hand, drives the transmission belt 43 to move through the connecting block 432, and the transmission belt 43 drives the moving plate 421 at the other end to move, and drives the wheel clamping rod 42 corresponding to the moving plate 421 to move, so that the wheel clamping rods 42 at both ends are close to each other until the wheels of the vehicle are clamped. Since the front and rear wheels are clamped at the same time, the parking angle of the vehicle can be adjusted to reach the "centering" state, so that the position adjustment of the vehicle in the horizontal direction can be achieved.

[0062] When the deformation of the elastic member 46 reaches a preset value, the induction sheet of the first engaging portion 444 approaches the sensor 47 and triggers the sensor 47. At this time, it can be determined that the clamping force applied to the wheel reaches the preset value. The driving member 44 is controlled to rotate in the opposite direction, and the nut 443 moves away from the moving seat 45. The elastic member 46 is slowly released, and the wheel clamping rods 42 at both ends are driven to move in a direction away from the wheel through the transmission belt 43 and the moving plate 421. In this way, the maximum clamping force of the tire can be controlled during the clamping process to prevent excessive clamping of the wheel from damaging the wheel or the clamping mechanism.

[0063] Then, the lifting drive assembly 30 simultaneously drives the lifting platform 20 to move in the vertical direction to lift the vehicle, thereby adjusting the position of the vehicle in the vertical direction.

[0064] The above-mentioned wheel clamping mechanism 40, vehicle position adjustment device and battery exchange parking device are configured with an elastic member 46 between the wheel clamping driving assembly and the wheel clamping rod 42, and the wheel clamping rod 42 is pushed by the elastic member 46 to clamp the vehicle, and the deformation of the elastic member 46 is detected by the sensor 47. When the deformation of the elastic member 46 exceeds a preset value, it is triggered, thereby determining that the clamping force of the wheel clamping rod 42 on the wheel reaches a maximum value, thereby achieving the purpose of controlling the clamping force of the clamped wheel.

[0065] Furthermore, the wheel clamping mechanism 40 can be integrally placed in the cavity 21 of the lifting platform 20 through the base 41, and the vehicle position adjustment devices correspond to the front wheels and the rear wheels respectively, so that they can be produced in a modular manner and then assembled in modules to form a battery swap parking device, which effectively improves the production and assembly efficiency of the battery swap parking device.
