Description

Lifting devices and vehicle lifting systems

[0001] The present application relates to the field of object lifting, and in particular to a lifting device and a lifting system for a cargo vehicle.

[0002] Lifting devices are used in many aspects of industrial production and daily life. Lifting devices can be used to lift objects from a lower position to a higher position for subsequent manufacturing, assembly, debugging or other operations.

[0003] When the weight of the object being lifted is large, the existing lifting device is prone to drop under pressure, resulting in poor stability of the lifting device.

[0004] Summary of the invention

[0005] In view of the above problems, the present application provides a jacking device and a cargo vehicle jacking system, which can improve the stability of the jacking device.

[0006] In a first aspect, the present application provides a lifting device, the lifting device comprising: a first actuator, the first actuator comprising a first actuating rod, the first actuating rod being configured to be movable in a first direction; a movable component, the movable component being connected to the first actuating rod and being configured to be movable along with the movement of the first actuating rod; and a lifting component, the lifting component being configured to lift an object to be lifted, wherein the lifting component is configured to be movable in a second direction by receiving a force applied by the movable component, and the second direction is different from the first direction. Since the movement direction of the first actuating rod of the first actuator can be different from the lifting direction of the lifting component, even if the lifting component is subjected to excessive pressure, it is not easy to cause the first actuating rod of the first actuator to move under pressure, thereby improving the stability of lifting and the accuracy of positioning.

[0007] In some embodiments, the movable component is configured to be able to move along the first direction with the movement of the first actuating rod. The movable component has an inclined surface, and the inclined surface is configured to apply a force to the lifting component when the movable component moves so that the lifting component moves in the second direction. The inclined surface enables self-locking of lifting to be achieved through a simple structure, thereby improving the stability of lifting and the accuracy of positioning.

[0008] In some embodiments, the inclination angle of the inclined surface relative to the first direction may be 10° to 45°. In some embodiments, the inclination angle of the inclined surface relative to the first direction may be 15° to 30°. In some embodiments, the inclination angle of the inclined surface relative to the first direction may be 20° to 25°. By properly selecting the inclination angle, the first actuating rod 11 of the first actuator 10 can be better prevented from moving under pressure, thereby better improving the stability of jacking and the accuracy of positioning.

[0009] In some embodiments, the first actuating rod is connected to the movable component via a first connecting mechanism. The first connecting mechanism can be configured to transmit the movement of the first actuating rod to the movable component, and the first connecting mechanism is configured to allow a movement margin between the first actuating rod and the movable component in the first direction. This connection method reduces the requirements for part processing accuracy, thereby reducing manufacturing costs.

[0010] In some embodiments, the first connecting mechanism may include a connecting rod and a connecting seat. The connecting rod is connected to the first actuating rod, and the connecting seat is connected to the movable component. Such an arrangement reduces wear on major components and facilitates assembly.

[0011] In some embodiments, the connecting rod may have a first limiting portion with an increased diameter, a second limiting portion with an increased diameter, and a third portion located between the first limiting portion and the second limiting portion. The connecting seat may have a notch. The first limiting portion and the second limiting portion are located on opposite sides of the outer side of the notch and are configured to limit the movement of the connecting rod in the first direction. The third portion is accommodated in the notch. Such a configuration can improve the stability of the mechanism and facilitate assembly.

[0012] In some embodiments, the notch has a length in the first direction. The length of the third portion is slightly greater than the length of the notch so that the connecting rod has the movement margin relative to the connecting seat in the first direction. Such a setting improves the stability of the mechanism, reduces the wear of parts, and can also reduce the requirements for part processing accuracy, thereby reducing manufacturing costs. Such a structure is also easier to assemble, reducing the requirements for the technical level of the assembler.

[0013] In some embodiments, the notch may be a U-shaped groove. The design of the U-shaped groove can facilitate the assembly of the connecting rod and the connecting seat.

[0014] In some embodiments, the connection base may have a step portion, the step portion including a first surface and a second surface perpendicular to each other, the movable component is seated on the first surface and fixedly connected to the movable component by a fastener disposed on the second surface. This can ensure that the connection base can be more reliably fixed to the movable component.

[0015] In some embodiments, the movable component may include at least one inclined wedge, the inclined wedge having the inclined surface, and the inclined surface is configured to apply a force to the lifting component when the movable component moves so that the lifting component moves in the second direction. The inclined wedge will not fall even when subjected to a large force, thereby improving the lifting stability and preventing the lifting from tilting.

[0016] In some embodiments, the lifting device may include at least two movable parts, and the at least two movable parts are connected by a connecting rod, so that the force can be applied to the lifting parts relatively evenly, stress concentration can be avoided, and the lifting can be made more stable.

[0017] In some embodiments, the movable component may be provided with one of a slide rail and a slider, and the frame of the lifting device may be provided with the other of the slide rail and the slider, and the slide rail and the slider cooperate with each other to enable the movable component to move in the first direction. In this way, the movable component can move steadily and smoothly in the first direction, thereby further improving the stability of lifting.

[0018] In some embodiments, the lifting surface of the lifting component for lifting the object may be provided with a plurality of fixing seats, and each fixing seat is provided with a plurality of universal balls. The provision of the universal balls makes it easy to adjust and position the lifted object. The provision of the plurality of fixing seats facilitates modular manufacturing, thereby increasing flexibility and reducing costs. The plurality of universal balls is also conducive to increasing the contact surface and better load bearing.

[0019] In some embodiments, the plurality of fixing seats may include a plurality of first fixing seats, wherein the universal balls on the first fixing seats may be arranged in a straight line, so that the lifted object can be well supported and adjusted, and the contact surface and the load-bearing capacity can be increased.

[0020] In some embodiments, the plurality of fixing seats may include a plurality of second fixing seats, wherein the universal balls on the plurality of second fixing seats may be arranged in a triangle, so as to better increase the contact surface and better disperse the pressure.

[0021] In some embodiments, the triangular arrangement of the universal balls on the plurality of second fixing seats may have at least two different orientations, which can further increase the contact area, disperse the pressure and improve the load-bearing capacity.

[0022] In some embodiments, the lifting device may further include a second actuator and a clamping mechanism, wherein the second actuator is configured to drive the clamping mechanism to move between a clamping position and a loosening position. In this way, the object or vehicle to be lifted can be preliminarily positioned before lifting to prevent position deviation.

[0023] In some embodiments, the lifting device may further include a positioning mechanism, the positioning mechanism is fixed to the lifting component, the positioning mechanism may include a third actuator and a positioning pin, and the third actuator may be configured to drive the positioning pin to move between an extended position and a retracted position along the second direction. Providing a positioning mechanism may allow the lifted object to be more accurately positioned relative to the lifting device.

[0024] In some embodiments, the positioning pins may be configured to fit with the positioning holes, and the outer contour of the cross section of at least one of the positioning pins may include a contact section and a non-contact section. The contact section contacts and fits with the inner surface of the positioning hole, and the non-contact section does not contact with the inner surface of the positioning hole. Such a setting can prevent over-positioning, and facilitates activities and installation and debugging while providing accurate positioning.

[0025] In some embodiments, the positioning pin can be configured to fit into a circular positioning hole. The contact section can include two opposite circular arcs, and the non-contact section can include four straight line segments respectively connected to the four endpoints of the two circular arcs, and the adjacent straight line segments are connected to each other. The lengths of the four straight line segments can be equal to each other. The positioning pin of such a configuration is easy to process and can prevent over-positioning, and is convenient for movement, installation and debugging while providing accurate positioning.

[0026] In some embodiments, the positioning mechanism may further include a slide slot, in which the positioning pin can move. The slide slot can limit the range of motion of the positioning pin.

[0027] In some embodiments, the third actuator may include a third actuating rod, and the third actuating rod may be coupled to the positioning pin via a connector. The positioning mechanism may be fixed to the lifting component via a fixing plate. The connector reduces the requirements for the machining accuracy of the parts and facilitates assembly and disassembly. The positioning mechanism is fixed to the lifting component via a fixing plate, which is conducive to accurate positioning after the lifting component is lifted into place.

[0028] In some embodiments, the lifting device may include a first detection device, which may be configured to detect whether the object to be lifted has been loaded. By detecting whether the object is loaded, it can be determined whether the object to be lifted has been loaded, thereby avoiding invalid lifting.

[0029] In some embodiments, the lifting device may include a second detection device, which may be configured to detect whether the object to be lifted is skewed. The second detection device may prevent lifting when the object is not properly loaded, thereby further improving the stability of the lifting.

[0030] In some embodiments, the first detection device and / or the second detection device may include an optical detector. The optical detector may include a through-beam detector. Using an optical sensor such as a through-beam sensor can accurately detect in a simple and low-cost manner.

[0031] In some embodiments, the first detection device may be arranged in the middle of at least one side of the object to be lifted, so that objects of various sizes can be detected whether they have been loaded.

[0032] In some embodiments, the second detection device may be arranged near at least one of the four corners of the object to be lifted, so as to better detect whether the object to be lifted is deflected in the vertical direction.

[0033] In some embodiments, the lifting component may include a crossbeam. A roller is provided at the bottom of the crossbeam, and the roller is configured to move on the inclined surface when the movable component moves so that the crossbeam moves in the second direction. By providing the roller as described above, the thrust required by the first actuator can be reduced and the lifting can be completed smoothly.

[0034] In some embodiments, the lifting device may further include a guide mechanism, which is configured to guide an object into the lifting device. The guide mechanism may prevent an object (eg, a cargo carrier) entering the lifting device from walking crookedly.

[0035] In some embodiments, the first actuator may further include at least one position detection sensor, and the position detection sensor is configured to detect whether the movement of the first actuating rod in the first direction reaches a predetermined position. Providing a position sensor can more accurately control the lifting of the lifting device to prevent over-lifting or under-lifting.

[0036] In some embodiments, the first actuator, the second actuator and / or the third actuator are cylinders. The cylinder can stably provide driving force. In the case where the first actuator is a cylinder, since the second direction as the lifting direction is different from the first direction as the cylinder extension direction, even if the cylinder is under-supplied with gas during the compression process, the first actuating rod of the cylinder is difficult to be pushed to extend and retract by the downward pressure, thereby achieving self-locking of the lifting surface.

[0037] In another aspect, some embodiments of the present invention provide a vehicle lifting system, characterized in that the vehicle lifting system comprises a lifting device according to any of the above embodiments and a vehicle, wherein the vehicle comprises a base plate, and the base plate is configured to be lifted by the lifting device in the second direction. In addition to the advantages brought by the above-mentioned lifting device, since the vehicle comprises a base plate for carrying objects that can be lifted separately, there is no need to lift the vehicle, which can improve the lifting capacity and adapt to various lifting needs.

[0038] In some embodiments, the base plate may have at least one positioning hole, which may cooperate with a positioning pin of the lifting device to accurately position the base plate of the vehicle relative to the lifting device.

[0039] In some embodiments, the carrier can be an automatic guided vehicle, which helps to automatically carry out conveying, lifting and other operations.

[0040] In some embodiments, the cargo carrier can be used to load the battery pack, which helps to achieve stable lifting during the manufacturing, assembly and / or maintenance of the battery.

[0068] Although the present application has been described with reference to some embodiments, various modifications may be made thereto and parts thereof may be replaced with equivalents without departing from the scope of the present application. In particular, the various technical features mentioned in the various embodiments may be combined in any manner as long as there is no structural conflict. The present application is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.

[0069] Lifting devices are widely used in various occasions in industrial production and daily life. The current lifting devices have the problem of low stability. Especially when the weight of the object being lifted is large, the lifting surface of the lifting device is easy to drop under the action of pressure, which causes the lifted object to be skewed and inaccurately positioned.

[0070] In order to improve the stability of the lifting device, an embodiment of the present application provides a lifting device, wherein the lifting device includes an actuator and a lifting component, wherein the actuator serves as a driving source for the lifting movement, and the lifting component is used to lift the object to be lifted in the lifting direction. The actuator is configured such that the movement direction of its actuating rod is different from the lifting direction of the lifting component.

[0071] Since the movement direction of the actuator rod of the actuator is different from the lifting direction, even if the lifting device is borne by a large load, the actuator rod of the actuator is difficult to be pushed by the downward pressure, thereby realizing self-locking of the lifting surface, thereby improving the stability of the lifting device and preventing the lifted object from being skewed and mispositioned.

[0072] To achieve this purpose, the lifting device according to the embodiment of the present application may include a movable component. The movable component is connected to the actuating rod and can move with the movement of the first actuating rod. The movable component is configured to apply a force to the lifting component when moving so that the lifting component moves in a lifting direction different from the movement direction of the actuating rod.

[0073] The lifting device disclosed in the embodiment of the present application can be used to lift any object to be lifted from a lower position to a higher position and return the object from a higher position to a lower position. The object can be, for example, a battery pack, a car or its parts, or any other part that needs to be lifted.

[0074] For the convenience of description, the following embodiments are described by taking a cargo vehicle lifting system 1000 according to an embodiment of the present application as an example.

[0075] Please refer to Figures 1 to 3. Figure 1 is a schematic structural diagram of a vehicle lifting system 1000 of an embodiment of the present application. Figures 2 and 3 respectively show a side view schematic diagram and a top view schematic diagram of an embodiment of a vehicle 200. The vehicle lifting system 1000 includes a lifting device 100 and a vehicle 200. The lifting device 100 is a device for raising an object to be lifted. The vehicle 200 is a transport vehicle for loading objects to be lifted. Although Figures 1 and 3 show that the vehicle can have wheels, as an alternative, the vehicle may not have wheels. The vehicle 200 may be a feeder vehicle, an automatic guided vehicle (AGV) or any other transport vehicle capable of carrying objects.

[0076] The object carrier 200 may have a base plate 201. The object to be lifted may be loaded on the base plate 201.

[0077] The base plate 201 can be raised and lowered separately. That is, when the vehicle 200 is in place in the lifting device 100, the lifting device 100 can only lift the base plate 201 and keep the vehicle 200 stationary. This can reduce the lifting load and facilitate lifting and positioning. As an alternative, the lifting device 100 can also directly lift the object to be lifted or lift the vehicle 200.

[0078] The jacking device 100 according to some embodiments of the present application is described below in conjunction with Figure 1 and Figures 4 to 6. Figure 4 is a schematic structural diagram of the jacking device of some embodiments of the present application. Figures 5A and 5B are schematic structural diagrams of a part of the jacking device of some embodiments of the present application observed from the bottom and the side, respectively. The jacking device 100 may include a first actuator 10, a movable component 20 and a jacking component 30. The first actuator 10 includes a first actuating rod 11. The first actuating rod 11 is configured to be able to move along a first direction. The movable component 20 is connected to the first actuating rod 11 and is configured to be able to move with the movement of the first actuating rod 11. The jacking component 30 is configured to jack an object to be jacked. The jacking component is configured to be able to receive the force applied by the movable component and move in a second direction. Wherein, the second direction is different from the first direction. Figure 4 shows a first direction X as an example and a second direction Z as an example.

[0079] The first actuator 10 is a driving source for lifting motion. The first actuator can be any device capable of driving the movable part to move. In some embodiments, the first actuator can be a driving source for outputting linear motion. In some embodiments, the first actuator 10 can be a cylinder. As an alternative, the first actuator 10 can also be a hydraulic cylinder, a motor or other types of power driving sources. The first actuator rod 11 is a power output component of the first actuator. Among them, being able to move along the first direction can be being able to reciprocate in the first linear direction. In some embodiments, the first direction can be the length direction of the first actuator rod 11, such as the direction along which the straight line X in FIG. 4 is located. Moving in the second direction can be reciprocating in the second linear direction. The second direction is the direction along which the lifting component 30 lifts the object and retracts the object, such as the direction along which the straight line Z in FIG. 4 is located. The second direction is different from the first direction in that the first direction and the second direction intersect each other. In some embodiments, the first direction can be perpendicular to the second direction. In some embodiments, the first direction can be a horizontal direction and the second direction can be a vertical direction.

[0080] According to the lifting device of the embodiment of the present application, since the movement direction of the first actuating rod 11 of the first actuator 10 can be different from the lifting direction of the lifting component 30, even if the lifting component 30 is subjected to excessive pressure, it is not easy to cause the first actuating rod 11 of the first actuator 10 to move under pressure, thereby realizing self-locking of the lifting, which can prevent the lifted object from shifting and tilting, and improve the stability of the lifting and the accuracy of positioning.

[0081] The movable component 20, as a motion transmission component, can convert the motion of the first actuating rod 11 of the first actuator 10 in the first direction into the motion of the lifting component 30 in the second direction. The movable component 20 can be any motion transmission component that can move with the motion of the first actuating rod 11 and can apply a force having a component in the second direction to the lifting component 30 when moving. For example, such a motion transmission component can include, but is not limited to, one or more of a transmission rod, a slider, a cam, a ratchet, and a gear.

[0082] In some embodiments, the movable component is configured to be movable along the first direction with the movement of the first actuating rod 11. The movable component 20 may have an inclined surface 22. The inclined surface 22 is configured to apply a force to the lifting component when the movable component moves so that the lifting component moves in the second direction.

[0083] In some embodiments, "the movable component 20 has an inclined surface" may mean that at least a portion of the surface of the movable component interacting with the lifting component 30 is inclined relative to the first direction. In other words, at least a portion of the surface of the movable component interacting with the lifting component 30 is not parallel to the first direction.

[0084] Since the movable component 20 has the inclined surface 22, when the movable component 20 moves, the inclined surface can exert a force on the lifting component 30. The force can have a component in the second direction, so that the lifting component 30 can move in the second direction. In this way, the lifting self-locking can be achieved with a simple structure, thereby improving the stability of lifting and the accuracy of positioning.

[0085] In some embodiments, the inclination angle of the inclined surface 22 relative to the first direction may be 10° to 45°. In some embodiments, the inclination angle of the inclined surface 22 relative to the first direction may be 15° to 30°. In some embodiments, the inclination angle of the inclined surface 22 relative to the first direction may be 20° to 25°. The inclination angle of the inclined surface 22 relative to the first direction may be 12°, 17°, 22°, 27°, 35° or 40°.

[0086] By properly selecting the tilt angle, the first actuating rod 11 of the first actuator 10 can be better prevented from moving under pressure, thereby better improving the stability of the jacking and the accuracy of the positioning.

[0087] 5A and 5B . In some embodiments, the first actuating rod 11 may be connected to the movable component 20 via a first connection mechanism 40. The first connection mechanism 40 may be configured to transfer the movement of the first actuating rod 11 to the movable component 20, and the first connection mechanism 40 may be configured to allow a movement margin between the first actuating rod 11 and the movable component 20 in the first direction.

[0088] The existence of a movement margin between the first actuating rod 11 and the movable component 20 in the first direction means that the first actuating rod 11 and the movable component 20 are not completely rigidly connected in the first direction but may have a slight relative displacement. The movement margin may be, for example, 0.5 mm to 1.5 mm, and may be 0.6 mm, 0.8 mm, 1.0 mm, 1.2 mm or 1.4 mm. Of course, when the size of the component increases, the movement margin may also be set larger.

[0089] Since the first actuating rod 11 is connected to the movable component 20 via the first connecting mechanism 40 in a manner with a certain movement margin, the requirements on the machining accuracy of the parts are reduced, thereby reducing the manufacturing cost.

[0090] With further reference to FIGS. 7A to 7C with reference to FIGS. 5A and 5B . FIG. 7A is a side view and a front view schematic diagram of a connecting rod and a connecting seat assembled together of the first connecting mechanism of some embodiments of the present application. FIG. 7B is a side view and a front view schematic diagram of a connecting rod of the first connecting mechanism of some embodiments of the present application. FIG. 7C is a side view and a front view schematic diagram of a connecting seat of the first connecting mechanism of some embodiments of the present application. In some embodiments, the first connecting mechanism 40 may include a connecting rod 41 and a connecting seat 42. The connecting rod 41 may be connected to the first actuating rod 11 (for example, connected by a nut 43 shown in FIGS. 5A and 5B ). The connecting seat 42 may be connected to the movable component 20. By separately arranging the connecting rod 41 and the connecting seat 42, the wear of the main components can be reduced and assembly can be facilitated.

[0091] In some embodiments, the connecting rod 41 may have a first limiting portion 411, a second limiting portion 412, and a third portion 413 located between the first limiting portion 411 and the second limiting portion 412. The first limiting portion 411 and the second limiting portion may be limiting portions with increased diameters. The connecting seat may have a notch 421. The first limiting portion 411 and the second limiting portion 412 are located on opposite sides of the outer side of the notch 421 and are configured to limit the movement of the connecting rod 41 in the first direction. The third portion 413 is accommodated in the notch 421. With such a structure, the stability of the mechanism can be improved and assembly is facilitated.

[0092] In some embodiments, the notch 421 has a length L2 in the first direction (see FIGS. 7A and 7C ). The length L1 of the third portion 413 (see FIG. 7B ) may be slightly greater than the length L2 of the notch 421 , so that the connecting rod 41 has the movement margin relative to the connecting seat 42 in the first direction.

[0093] The limit portion with increased diameter means that the diameter of the limit portion is larger than the diameter of other portions of the connecting rod 41. "The length L1 of the third portion 413 is slightly larger than the length L2 of the notch 421, so that the connecting rod 41 has the movement margin relative to the connecting seat 42 in the first direction" means that there may be a slight relative displacement between the connecting rod 41 and the connecting seat 42 in the first direction. Similar to the above, the clearance may be 0.5 mm to 1.5 mm, and may be 0.6 mm, 0.8 mm, 1.0 mm, 1.2 mm or 1.4 mm. In the case where the size of the component increases, the clearance may be set larger.

[0094] By using the connecting rod 41 and the connecting seat 42 as described above, the stability of the mechanism can be improved and the wear of the parts can be reduced. In addition, the requirements for the processing accuracy of the parts can be reduced, thereby reducing the manufacturing cost. In addition, such a structure is easy to assemble, which reduces the requirements for the technical level of the assembler.

[0095] In some embodiments, as shown in Figures 7A and 7C, the notch 421 is a U-shaped groove. As shown in Figure 5A, the design of the U-shaped groove can facilitate the assembly of the connecting rod 41 and the connecting seat 42.

[0096] In some embodiments, as shown in FIG7A , the connection seat 42 may have a step portion 422. The step portion 422 may include a first surface 4221 and a second surface 4222 that are perpendicular to each other, and the movable component 20 is seated on the first surface 4221 and fixedly connected to the movable component 20 by a fastener 44 disposed on the second surface 4222. The fastener 44 may be a bolt or a similar component.

[0097] The extension direction of the first surface 4221 can be set to be the same as the extension direction of the bottom surface of the movable component 30, so that the bottom surface of the movable component 20 can be placed on the first surface. In an embodiment, the extension direction of the first surface 4221 can be the same as the first direction. For example, the first surface can be set in a horizontal direction. The second surface 4222 can be perpendicular to the first surface 4221, for example, can be set in a vertical direction.

[0098] The step portion 422 as described above ensures that the connecting seat 42 can be more reliably fixed on the movable component 20 .

[0099] In some embodiments, as shown in Figures 4 to 6, the movable component 20 includes at least one inclined wedge, and the inclined wedge has an inclined surface 22. The inclined surface 22 is configured to apply a force to the lifting component 30 when the movable component 20 moves, so that the lifting component 30 moves in the second direction.

[0100] The inclined wedge may be a slider having an inclined surface. In some embodiments, "the inclined wedge has an inclined surface 22" may mean that at least a portion of the surface (e.g., the upper surface) of the inclined wedge that interacts with the lifting component 30 is inclined relative to the surface opposite to the surface (e.g., the lower surface) or relative to the direction along which the inclined wedge moves (e.g., the first direction). In other words, at least a portion of the surface (e.g., the upper surface) of the inclined wedge that interacts with the lifting component 30 is not parallel to the surface (e.g., the lower surface) opposite to the surface or the direction along which the inclined wedge moves (e.g., the first direction). "The inclined wedge has an inclined surface 22" does not exclude that the surface of the inclined wedge that interacts with the lifting component 30 may have a non-inclined surface. In some embodiments, the non-inclined surface is connected to the inclined surface, and the connected portion serves as the starting point and / or end point of the lifting formation.

[0101] The inclined wedge is a movable component used to convert the movement of the first actuating rod 11 in the first direction into the movement of the lifting component 30 in the second direction. The inclined wedge will not drop even when subjected to a large force, thereby improving the lifting stability and preventing the lifting from tilting.

[0102] As described above, for the inclined wedge, in some embodiments, as shown in FIG6 , the inclination angle θ of the inclined surface 22 relative to the first direction may be 10° to 45°. In some embodiments, the inclination angle θ of the inclined surface 22 relative to the first direction may be 15° to 30°. In some embodiments, the inclination angle θ of the inclined surface 22 relative to the first direction may be 20° to 25°. The inclination angle θ of the inclined surface 22 relative to the first direction may be 12°, 17°, 22°, 27°, 35° or 40°.

[0103] In some embodiments, the lifting device 100 includes at least two movable components 20, and the at least two movable components 20 are connected by a connecting rod 23. In the embodiment shown in Figures 5A and 5B, the lifting device 100 includes two movable components 20. One of the movable components 20 is connected to the first actuating rod 11 of the first actuator 10. The two movable components 20 are connected by a connecting rod 23.

[0104] The movable parts 20 are connected by connecting rods 23, so they can move in an integrated manner. Since a plurality of movable parts are provided, a force can be applied to the lifting part 30 relatively evenly, stress concentration can be avoided, and lifting can be made more stable.

[0105] In some embodiments, one of the slide rail 24 and the slider 25 is provided on the movable component 20, and the other of the slide rail 24 and the slider 25 is provided on the frame 21 of the jacking device 20, and the slide rail 24 and the slider 25 cooperate with each other so that the movable component 20 can move in the first direction.

[0106] In the embodiments shown in FIGS. 4 to 6 , the movable component 20 is provided with a slide rail 24. The slide rail 24 can be connected to the movable component 20 as a whole. A slider 25 is provided on the frame 21 of the lifting device 20. The slider 25 is fixed on the frame 21. The movable component 20 moves in the first direction (the X direction in FIG. 4 ) by the movement of the slide rail 24 on the slider 25.

[0107] By providing the slide rail and the slider, the movable component 20 can be moved steadily and smoothly in the first direction, thereby further improving the stability of the lifting. In addition, providing the slide rail on the movable component 20 can reduce space occupation, which is particularly beneficial for the case where the movable component has a long travel distance.

[0108] In some embodiments, as shown in FIG4 , a plurality of fixing seats 32 may be provided on the lifting surface 31 of the lifting component 30 for lifting the object. Each fixing seat is provided with a plurality of universal balls 33. In some embodiments, the plurality of fixing seats 32 may be arranged at equal intervals on the lifting component 30.

[0109] A universal ball is a sphere that can roll in all directions around the center of the ball. Therefore, the object being lifted can move on the surface formed by the universal balls, so that it is convenient to adjust and position the object being lifted. Providing multiple fixed seats and arranging multiple universal balls on each fixed seat facilitates modular arrangement and adjustment of the universal balls, thereby increasing flexibility and reducing costs. In addition, providing multiple universal balls is also conducive to increasing the contact surface and facilitating load bearing. Arranging multiple fixed seats 30 at equal intervals can achieve a better pressure dispersion effect with fewer universal balls.

[0110] In some embodiments, the plurality of fixing seats 32 may include a first fixing seat 321, wherein the universal balls 33 on the first fixing seat 321 are arranged along a straight line, as shown in Fig. 4. In some embodiments, the straight line may extend along the length direction of the lifting component.

[0111] The universal balls arranged in a straight line can well support and adjust the lifted objects, and can increase the contact surface and improve the load-bearing capacity.

[0112] In some embodiments, additionally or alternatively, as shown in Fig. 4, the plurality of fixing seats 32 may include a plurality of second fixing seats 322. The universal balls 33 on the plurality of second fixing seats 322 are arranged in a triangle.

[0113] The universal balls 33 are arranged in a triangle, which means that the universal balls form the vertices of the triangle. The universal balls arranged in a triangle can better increase the contact surface and better disperse the pressure.

[0114] In some embodiments, as shown in FIG. 4 , the triangular arrangement of the universal balls 33 on the plurality of second fixing seats 322 has at least two different orientations.

[0115] The triangles arranged with the same orientation means that the directions along which the corresponding sides of the triangles are arranged are the same. Correspondingly, the triangles arranged with different orientations means that the directions along which the corresponding sides of the triangles are arranged are different. In other words, the two triangles arranged with different orientations means that the two triangles are rotated relative to each other by a predetermined angle.

[0116] The universal balls 33 on the second fixing seat 322 are arranged in a triangle with different orientations to further increase the contact area, disperse the pressure and improve the load-bearing capacity.

[0117] In some embodiments, as shown in FIG. 4 , a plurality of first fixing seats 321 having universal balls 33 arranged in a straight line and a plurality of second fixing seats 322 having universal balls 33 arranged in a triangular shape are provided on the lifting surface 31 of the lifting component 30. In some embodiments, the first fixing seats 321 may be provided on the two end portions of the lifting surface 31 of the lifting component 30. The second fixing seats 322 may be provided between the first fixing seats 321. In some embodiments, each second fixing seat 322 having universal balls 33 arranged in a triangular shape may have the same structure. When arranged, at least one second fixing seat is arranged to be rotated by a predetermined angle (e.g., 180 degrees) relative to an adjacent second fixing seat. This facilitates modular production, thereby better increasing the contact area, dispersing the pressure, and improving the bearing capacity at a lower cost.

[0118] In some embodiments, as shown in Figures 1 and 4, the lifting device 100 further includes a second actuator 50 and a clamping mechanism 51. The second actuator 50 is configured to drive the clamping mechanism 51 to move between a clamping position (see the clamping mechanism 51 shown by solid lines in Figures 1 and 4) and a loosening position (see the clamping mechanism 51 shown by dotted lines in Figures 1 and 4).

[0119] The clamping mechanism 51 can be any type of clamp. The clamping position is the position where the clamping mechanism 51 clamps the object to be lifted or the vehicle carrying the object to limit its movement. The release position is the position where the clamping mechanism 51 no longer clamps the object to be lifted or the vehicle carrying the object. In some embodiments, as shown in Figure 1, in the clamping position, the clamping mechanism 51 can clamp the vehicle 200 at both ends of the vehicle 200 in the first direction (the driving direction of the vehicle or the X direction in Figure 4) to limit its movement in the first direction. By setting the clamping mechanism 51, the object to be lifted or the vehicle can be preliminarily positioned before lifting.

[0120] Further reference is made to FIG. 4 and FIG. 8 to FIG. 10 below. In some embodiments, the lifting device 100 further includes a positioning mechanism 60. The positioning mechanism 60 may be fixed to the lifting component 30. The positioning mechanism 60 includes a third actuator 61 and a positioning pin 62. The third actuator 61 is configured to drive the positioning pin 62 to move between an extended position and a retracted position along the second direction.

[0121] The positioning mechanism 60 is a device for positioning the object to be lifted on a lifting plane (a plane perpendicular to the second direction). The extended position is a position in which the positioning pin 62 is extended in the second direction so that the positioning pin 62 can be inserted into and fit into the positioning hole 202 in the object to be lifted. The retracted position is a position in which the positioning pin 62 is retracted in the second direction so that the positioning pin 62 withdraws from the positioning hole 202. The object to be lifted may be, for example, the base plate 201 of the vehicle 200, the vehicle 200 and / or an object loaded on the base plate 201 of the vehicle 200.

[0122] Providing the positioning mechanism 60 can allow the object to be lifted to be positioned more accurately relative to the lifting device 100 .

[0123] In some embodiments, the positioning pin 62 is configured to be adapted to the positioning hole 202. Referring to Figures 11 and 12, Figure 11 is a schematic top view of the positioning mechanism of the jacking device of some embodiments of the present application. Figure 12 is an enlarged cross-sectional view of the positioning pin of the positioning mechanism of some embodiments of the present application. As shown in Figure 12, the outer contour of the cross section of at least one positioning pin of the positioning pin 62 has a contact section 621 and a non-contact section 622. The contact section 621 is in contact with the inner surface of the positioning hole 202, and the non-contact section 622 is not in contact with the inner surface of the positioning hole.

[0124] The cross-sectional outer contour of the positioning pin as described above can reduce one degree of freedom in positioning, prevent over-positioning, and facilitate activities and installation and debugging while ensuring accurate positioning.

[0125] In some embodiments, the locating pin 62 is configured to be adapted to fit with the circular locating hole 202. As shown in Figure 12, the contact section 621 includes two opposite circular arcs. The non-contact section 622 includes four straight line segments connected to the four endpoints of the two circular arcs, respectively, and the adjacent straight line segments are connected to each other. The lengths of the four straight line segments can be equal to each other. Thus, a locating pin with a rhombus-like cross section can be formed. The rhombus-like shape can be regarded as a rhombus in which two opposite corners are replaced by arcs suitable for contacting and matching with the inner surface of the circular locating hole.

[0126] The positioning pin with such a structure is easy to process and can prevent over-positioning, which is convenient for activities, installation and debugging while ensuring accurate positioning.

[0127] In one embodiment, the positioning mechanism 60 further includes a slide groove 63 , and the positioning pin 62 can move in the slide groove 63 .

[0128] The slide groove 63 is a channel for the positioning pin to slide therein. The slide groove 63 can limit the range of motion of the positioning pin.

[0129] In one embodiment, referring to Fig. 9 and Fig. 10, the third actuator 61 includes a third actuating rod 611. The third actuating rod 611 can be connected to the positioning pin 62 via a connector 64. Referring to Fig. 8 and Fig. 9, the positioning mechanism 60 can be fixed to the lifting component 30 via a fixing plate 65.

[0130] The third actuating rod 611 can be connected to the positioning pin 62 through the connector 64 to reduce the requirements for component processing accuracy and facilitate assembly and disassembly. The positioning mechanism is fixed to the lifting component through a fixing plate, which is conducive to accurate positioning after the lifting component is lifted into place.

[0131] The first detection device and the second detection device of the lifting device 100 are described below in conjunction with Figure 1 and Figure 4. In one embodiment, the lifting device 100 includes a first detection device 70, which is configured to detect whether the object to be lifted has been loaded.

[0132] By providing a first detection device for detecting whether the object to be lifted has been loaded, it can be determined whether the object to be lifted has been loaded, thereby avoiding invalid lifting.

[0133] The first detection device 70 may be any sensor capable of detecting whether an object exists. As a non-limiting embodiment, the first detection device may include an optical sensor. The optical sensor is a sensor that detects an object using optical principles. As a non-limiting embodiment, the optical sensor may include a through-beam sensor. A through-beam sensor is a sensor that can determine whether an object exists by comparing the states of emitted and received light. In the case where the light emitted by the optical sensor is blocked by the object to be lifted, the optical sensor may receive a signal to determine the existence of the object to be lifted.

[0134] Optical sensors such as through-beam sensors can be used to accurately detect the presence of an object in a simple and cost-effective manner.

[0135] In one embodiment, the lifting device comprises a second detection device 71. The second detection device is configured to detect whether the object to be lifted is deflected.

[0136] The second detection device 71 may be any sensor capable of detecting whether the object to be lifted is deflected. As a non-limiting embodiment, the first detection device may include an optical sensor. As a non-limiting embodiment, the optical sensor may include a through-beam sensor.

[0137] Optical sensors such as through-beam sensors can be used to accurately detect whether an object is tilted in a simple and cost-effective manner.

[0138] In one embodiment, the first detection device 70 is disposed in the middle of at least one side of the object to be lifted.

[0139] The at least one side of the object to be lifted can be any one side or multiple sides of the object to be lifted, as long as it can be sensed from the side whether the object to be lifted has been loaded. The first detection device 70 is arranged in the middle of at least one side of the object to be lifted so that objects of various sizes can be detected whether they have been loaded.

[0140] In one embodiment, the second detection device 71 is disposed near at least one of the four corners of the object to be lifted.

[0141] By setting the second detection device 71 near at least one of the four corners of the object to be lifted, when the height of the corner deviates from the predetermined range, the second detection device 71 (such as an optical sensor) can detect the position deviation of the corner, thereby accurately determining whether the object to be lifted is skewed.

[0142] In one embodiment, as shown in Fig. 4, the lifting component 30 includes a crossbeam 34. A roller 35 is provided at the bottom of the crossbeam 34. The roller 35 is configured to move on the inclined surface 22 when the movable component 20 moves so that the crossbeam 34 moves in the second direction.

[0143] To this end, the cross beam 34 can move in the second direction through the cooperation between one of the slide rails and the sliders provided on the cross beam 34 and the other of the slide rails and the sliders provided on the frame of the jacking device.

[0144] By providing the roller 35 as described above, the thrust required by the first actuator can be reduced and the lifting can be smoothly performed.

[0145] In one embodiment, as shown in FIG. 1 and FIG. 4 , the lifting device 100 may further include a guide mechanism 80 , and the guide mechanism 80 is configured to guide an object to enter the lifting device 100 .

[0146] The guide mechanism may be any mechanism that can guide the object into the lifting device, such as a guide roller, a guide wheel, a guide wall, etc. The guide mechanism can prevent the object (such as a vehicle) entering the lifting device 100 from walking crookedly.

[0147] In one embodiment, as shown in Fig. 4, the first actuator 10 may have at least one position detection sensor 12. The position detection sensor 12 is configured to detect whether the movement of the first actuating rod 11 in the first direction reaches a predetermined position.

[0148] The position sensor 12 may be any sensor that can sense the position of the object to be measured and convert the sensing result into an output signal. The position sensor 12 may include, for example, a contact position sensor (such as a travel switch) or a non-contact position sensor (such as a proximity sensor). The position sensor can more accurately control the lifting of the lifting device to prevent over-lifting or under-lifting.

[0149] In some embodiments, the first actuator 10, the second actuator 50 and / or the third actuator 61 are cylinders.

[0150] The cylinder can stably provide driving force. In addition, when the first actuator 10 is a cylinder, since the second direction as the lifting direction is different from the first direction as the cylinder extension direction, even if the cylinder is under-supplied with gas during the compression process, the first actuating rod of the cylinder is difficult to be pushed to extend and retract by the downward pressure, thereby achieving self-locking of the lifting surface.

[0151] On the other hand, as shown in FIG1 , some embodiments of the present application further provide a vehicle lifting system 1000. The vehicle lifting system may include a lifting device 100 according to any of the above embodiments and a vehicle 200. The vehicle 200 includes a base plate 201. The base plate 201 is configured to be lifted by the lifting device 100 in the second direction.

[0152] Since the object carrier includes the base plate 201 for carrying objects which can be lifted up independently, there is no need to lift the object carrier, so the lifting capacity can be improved to meet various lifting needs.

[0153] In some embodiments, as shown in FIG. 3 , the substrate 201 has at least one positioning hole 202 .

[0154] The positioning holes 202 are used to match the positioning pins 62 on the lifting device 100. The positioning holes can accurately position the base plate 201 of the vehicle relative to the lifting device 100. The positioning holes 201 can be arranged in any number at any position of the base plate 201. In some embodiments, the positioning holes 201 can be arranged near the opposite corners of the base plate. This can achieve a better positioning effect.

[0155] In some embodiments, the carrier 200 is an automatic guided vehicle (AGV), which helps to automatically perform transport, lifting and other operations.

[0156] In some embodiments, the cargo carrier 200 is used to load a battery pack, which helps to achieve stable lifting during the manufacturing, assembly and / or maintenance of the battery.

[0157] According to some embodiments of the present application, referring to FIGS. 1 to 6 , the present application provides a vehicle lifting system 1000. The lifting system 1000 includes a lifting device 100 and a vehicle 200. The vehicle 200 includes a base plate 201 for carrying an object. The lifting device 100 is used to lift the base plate 201. The lifting system 1000 may have at least one lifting device. In the embodiment shown in FIG. 1 , a lifting device 100 is provided on each side of the base plate 201. Each lifting device 100 is constructed as follows. The lifting device 100 includes a cylinder 10. The cylinder 10 has a first actuating rod 11. The first actuating rod 11 can move in a horizontal direction. The first actuating rod 11 is connected to an inclined wedge 20 through a first connecting mechanism 40, so that the inclined wedge 20 can move in a horizontal direction with the movement of the first actuating rod 11. The inclined wedge 20 can be connected to another inclined wedge located on the other side of the cylinder 10 through a connecting rod 23, so that the two inclined wedges 20 can move in a horizontal direction as a whole. Both of the two wedges have an inclined surface 22. The inclined surface 22 is configured to apply a force to the cross beam 34 as the lifting component 30 when the wedge moves in the horizontal direction, so that the cross beam 34 moves in the vertical direction. As a result, the horizontal movement of the first actuating rod 11 of the cylinder is converted into a lifting movement of the cross beam 34 in the vertical direction, thereby improving the stability of the lifting.

[0158] The working principle of the vehicle lifting system 1000 according to some embodiments of the present application is as follows. The vehicle 200 is brought to a predetermined position in the lifting device 100. After the vehicle 200 is in place, the second actuator 50 drives the clamping mechanism 51 to clamp the vehicle 200. The first actuating rod 11 of the first actuator 10 of the lifting device 100 moves in the first direction to drive the lifting component 30 to move in the second direction, thereby lifting the substrate 201 of the vehicle 200 off the vehicle. After the substrate 201 is lifted into place, the third actuator 61 drives the positioning pin 62 to extend and fit with the positioning hole 202 in the substrate 201, thereby positioning the substrate 201. After completing the required operation, the positioning pin 62 is disengaged from the positioning hole 202 and retracted. After the positioning pin 62 retracts, the first actuator 10 drives the substrate 201 to move in the second direction in the opposite direction and descend to the vehicle 200. The second actuator 50 drives the clamping mechanism 51 to release the vehicle 200. The vehicle 200 leaves the lifting device 100 .
