Description

Technical Field

[0001] The present application relates to the technical field of battery disassembly and assembly equipment, and in particular to a lifting device and an electrical equipment. Background Art

[0002] The information provided in this section is only background information related to the present disclosure, and it is not necessarily prior art.

[0003] Currently, due to the increasing requirements of the market for the cruising range of the whole vehicle, the weight of the battery device is also increasing, which brings great challenges to the after-sales maintenance and disassembly of the battery device.

[0004] In the related art, the battery device is usually laid flat on the mounting plate in the battery compartment. During disassembly, the battery device is generally fixed with a rope, and then it can only be disassembled by dragging it with multiple people. The disassembly efficiency is low, and it consumes a large amount of manpower and material resources. Summary of the Utility Model

[0005] The purpose of the present application is to provide a lifting device and an electrical equipment to improve the disassembly efficiency of the battery. This purpose is achieved through the following technical solutions:

[0006] In a first aspect, the present application provides a lifting device for lifting a battery device. The battery device is arranged on a mounting plate. The lifting device includes: a sleeve configured to be connected to the battery device and having a first installation cavity; a sphere, a part of the sphere is received in the first installation cavity and is configured to abut against the mounting plate, and the sphere is configured to be able to roll relative to the mounting plate; a top rod assembly threadedly connected to the inner wall surface of the first installation cavity and configured to abut against the sphere.

[0007] According to the lifting device provided by the present application, the sleeve is threadedly connected to the threaded hole of the hanging plate. A first installation cavity for receiving the sphere is defined in the sleeve. A part of the sphere is received in the first installation cavity, and a part of the sphere is located outside the first installation cavity and is used for contact connection with the mounting plate below the battery device. The top rod assembly is threadedly connected to the inner wall surface of the first installation cavity of the sleeve, so that the distance between the part of the top rod assembly located in the sleeve and the sphere can be adjusted. In this way, when a part of the top rod assembly extends into the first installation cavity and abuts against the sphere, and the sleeve is driven to rotate relative to the top rod assembly, the sleeve can drive the battery device to rise, so that a gap can be formed between the battery device and the mounting plate. When the battery device is dragged in a preset direction, by adjusting the tightness between the top rod assembly and the sphere, the sphere can roll relative to the mounting plate, so that the sliding friction between the battery device and the mounting plate is changed into rolling friction, and thus it is convenient to drag the battery device, and the disassembly efficiency of the battery device is improved.

[0008] In addition, the jacking device provided according to the present application may further have the following additional technical features:

[0009] In some embodiments of the present application, the ejector rod assembly includes: a cover, the cover having a second installation cavity, a first end of the cover being located in the first installation cavity and threadedly connected to an inner wall surface of the first installation cavity, and a second end of the cover being located outside the first installation cavity; an ejector rod, the ejector rod being threadedly connected to an inner wall surface of the second installation cavity, and a part of the ejector rod passing through the second installation cavity and extending into the first installation cavity to abut against the sphere.

[0010] In the above technical solution, the second installation cavity of the cover is used for the ejector rod to extend into the first installation cavity of the sleeve, so that the ejector rod can abut against the sphere, and the ejector rod is threadedly connected to the inner wall surface of the second installation cavity. When the ejector rod is rotated, the pressing force of the ejector rod against the sphere can be adjusted, so as to facilitate the sphere to roll relative to the mounting plate, thereby driving the battery device to roll relative to the mounting plate.

[0011] In some embodiments of the present application, an outer diameter of the second end of the cover is greater than an outer diameter of the first end of the cover, and the outer diameter of the second end of the cover is greater than an inner diameter of the first installation cavity, and one end of the sleeve away from the sphere can abut against the second end of the cover.

[0012] In the above technical solution, by setting the outer diameter of the second end of the cover to be greater than the outer diameter of the first end of the cover, the first end of the cover can extend into the first installation cavity of the sleeve, and the second end of the cover is located outside the sleeve, and when the sleeve rotates relative to the cover, it can abut against the second end of the cover to play a limiting role and reduce the risk of the sleeve and the cover separating.

[0015] In some embodiments of the present application, the ejector rod includes a first rod body and a second rod body, the first rod body being located outside the cover, the second rod body passing through the second installation cavity and extending into the first installation cavity to abut against the sphere, wherein the second rod body has a third installation cavity, and a part of the sphere is accommodated in the third installation cavity.

[0016] In the above technical solution, the first rod body of the ejector rod is located outside the cover, the second rod body passes through the second installation cavity of the cover and extends into the second installation cavity of the sleeve, and abuts against the sphere arranged in the sleeve. Moreover, the second rod body is threadedly connected to the inner wall surface of the cover, so that the position of the second rod body in the second accommodation cavity can be adjusted, thereby the distance between the second rod body and the sphere can be adjusted, and the sphere can be freely rotated in the sleeve.

[0017] In some embodiments of the present application, the inner diameter of the third installation cavity is smaller than the outer diameter of the sphere.

[0018] In the above technical solution, the inner diameter of the third installation cavity being smaller than the outer diameter of the sphere can not only enable the second rod body to abut against the sphere, but also reduce the risk that the sphere enters the third installation cavity and cannot roll relative to the mounting plate.

[0019] In some embodiments of the present application, a second driving portion is provided on the outer peripheral surface of the end of the sleeve away from the sphere, and the second driving portion is used for cooperating and connecting with a second driving member.

[0020] In the above technical solution, the second driving portion is cooperatively connected with the sleeve through the second driving portion, so as to facilitate driving the sleeve to rotate relative to the ejector rod assembly. And the sleeve is threadedly connected to the threaded hole on the hanging plate of the battery device, so when the sleeve rotates relative to the ejector rod, it can drive the battery device to rise or fall. Thus, after the battery device rises relative to the mounting plate, by dragging the battery device, the sphere can roll relative to the mounting plate, and further the battery device can be quickly disassembled.

[0021] In some embodiments of the present application, the sleeve is coaxially arranged with the cover and the ejector rod respectively.

[0022] In the above technical solution, by coaxially arranging the sleeve with the cover and the ejector rod respectively, the risk of jamming when the sleeve rotates relative to the cover can be reduced, and the risk of jamming when the ejector rod rotates relative to the cover can also be reduced, which helps to improve the installation and disassembly efficiency of the product.

[0049] Currently, from the perspective of the development of the market situation, the application of battery devices is becoming more and more widespread. Battery devices are not only applied to energy storage power systems such as hydraulic, thermal, wind, and solar power stations, but also widely applied to electric transportation tools such as electric bicycles, electric motorcycles, and electric vehicles, as well as multiple fields such as military equipment and aerospace. With the continuous expansion of the application fields of battery devices, the market demand is also constantly increasing.

[0050] Among them, for the battery device installed on the mounting plate in the battery compartment, when disassembling, generally a rope is used to fix the battery device, and then multiple people are required to drag it to disassemble the battery device. The disassembly efficiency is low, and it consumes a large amount of manpower and material resources.

[0051] In order to solve the problems of low efficiency and waste of a large amount of manpower and material resources when disassembling a battery device, the present application designs a jacking device for jacking the battery device from a mounting plate to a preset height, including a sleeve, a sphere, and a jacking rod mechanism. The sleeve is configured to be connected to the battery device. A first installation cavity is defined in the sleeve. Part of the sphere is received in the first installation cavity, and part of the sphere is located outside the first installation cavity and is configured to abut against the mounting plate. The sphere is capable of rolling relative to the mounting plate. Part of the jacking rod assembly is located in the first installation cavity and is threadedly connected to the inner wall surface of the first installation cavity, and the jacking rod assembly is capable of abutting against the sphere. In this way, when the jacking rod assembly abuts against the sphere, by driving the sleeve to rotate relative to the jacking rod assembly, the battery device can be separated from the mounting plate, so as to facilitate dragging the battery device. When dragging the battery device, the sphere can roll relative to the mounting plate, thereby improving the disassembly efficiency of the battery device.

[0052] The jacking device disclosed in the embodiments of the present application is used to disassemble the battery device, specifically for jacking the battery device from the mounting plate to a preset height, and changing the sliding friction between the battery device and the mounting plate into rolling friction when dragging the battery device, so as to facilitate dragging the battery device and contribute to quickly disassembling the battery device.

[0053] Please refer to Figures 1 to 5 , Figure 1 which is a schematic structural view of the jacking device and the battery device in a pre-tightened state provided by some embodiments of the present application; Figure 2 which is a schematic structural view of the battery device in a jacked-up state provided by some embodiments of the present application; Figure 3 which is a schematic structural view of the assembly structure of a plurality of jacking devices and the hanging plate of the battery device provided by some embodiments of the present application; Figure 4 which is a schematic structural view of the jacking device provided by some embodiments of the present application; Figure 5 is Figure 4 the cross-sectional structural view in the A-A direction in. Embodiments of the present application provide a jacking device 20 for jacking a battery device 100. The battery device 100 is arranged on a mounting plate 10. The jacking device 20 includes a sleeve 21, a sphere 23, and a jacking rod assembly 22. Among them, the sleeve 21 is configured to be threadedly connected to the battery device 100, and the sleeve 21 has a first installation cavity 211; part of the sphere 23 is received in the first installation cavity 211 and is configured to abut against the mounting plate 10, and the sphere 23 is configured to be capable of rolling relative to the mounting plate 10; the jacking rod assembly 22 is threadedly connected to the inner wall surface of the first installation cavity 211 and is configured to abut against the sphere 23.

[0054] As an example, the battery device 100 includes a battery box and battery cells arranged in the battery box. The battery box has an upper box body and a lower box body. A hanging plate 101 is arranged on the outer peripheral side of the lower box body. When the battery device 100 is installed on the mounting plate 10 of the battery compartment, both the lower box body and the hanging plate 101 are in contact with the mounting plate 10.

[0055] As an example, the hanging plate 101 is provided with threaded holes, and the outer peripheral side of the sleeve 21 is provided with external threads, and the sleeve 21 is threadedly connected to the hanging plate 101. The inside of the sleeve 21 is a hollow structure and forms a first installation cavity 211.

[0056] As an example, the sphere 23 is a metal sphere 23, such as a copper ball or a stainless steel ball.

[0057] It can be understood that the sphere 23 is located on the side of the sleeve 21 facing the mounting plate 10, and the outer diameter of the sphere 23 is adapted to the inner diameter of the first installation cavity 211, that is, the sphere 23 can be in contact connection with the inner wall surface of the first installation cavity 211 and can roll.

[0058] It can be understood that the ejector rod assembly 22 is threadedly connected to the inner wall surface of the first installation cavity 211, that is, a part of the ejector rod assembly 22 is located inside the first installation cavity 211, and external threads are provided on the outer peripheral side of the ejector rod assembly 22, and internal threads are provided on the inner wall surface of the first installation cavity 211, so that the ejector rod assembly 22 can be threadedly connected to the inner wall surface of the first installation cavity 211. In addition, when the ejector rod assembly 22 rotates relative to the sleeve 21, the length of the ejector rod assembly 22 extending into the first installation cavity 211 can be adjusted to adjust the pressing force between it and the sphere 23.

[0059] By connecting the sleeve 21 to the battery device and defining a first installation cavity 211 for accommodating the sphere 23 in the sleeve 21, part of the sphere 23 can be accommodated in the first installation cavity 211, and part of the sphere 23 is located outside the first installation cavity 211 for abutting against the mounting plate 10 below the battery device 100. The ejector rod assembly 22 is threadedly connected to the inner wall surface of the first installation cavity 211 of the sleeve 21, so that the distance between the part of the ejector rod assembly 22 located inside the sleeve 21 and the sphere 23 can be adjusted. In this way, when a part of the ejector rod assembly 22 extends into the first installation cavity 211 to abut against the sphere 23 and drives the sleeve 21 to rotate relative to the ejector rod assembly 22, the sleeve 21 can drive the battery device 100 to rise, so that a gap can be formed between the battery device 100 and the mounting plate 10. When the battery device 100 is dragged along a preset direction, by adjusting the tightness between the ejector rod assembly 22 and the sphere 23, the sphere 23 can roll relative to the mounting plate 10, so that the sliding friction between the battery device 100 and the mounting plate 10 is changed into rolling friction, and thus the battery device 100 can be easily dragged, improving the disassembly efficiency of the battery device 100.

[0060] Please refer to Figures 4 to 8 , Figure 6 which is a schematic structural diagram of the sleeve provided in some embodiments of the present application; Figure 7 which is a schematic structural diagram of the cover provided in some embodiments of the present application. Figure 8Schematic diagram of the structure of the ejector rod provided by some embodiments of the present application. According to some embodiments of the present application, the ejector rod assembly 22 includes a cover 221 and an ejector rod 222. Among them, the cover 221 has a second installation cavity 2211. The first end of the cover 221 is located in the first installation cavity 211 and is threadedly connected to the inner wall surface of the first installation cavity 211. The second end of the cover 221 is located outside the first installation cavity 211. The ejector rod 222 is threadedly connected to the inner wall surface of the second installation cavity 2211, and a part of the ejector rod 222 passes through the second installation cavity 2211 and extends into the first installation cavity 211 to abut against the sphere 23.

[0061] As an example, the cover 221 is a cylinder with a hollow structure inside.

[0062] It can be understood that an external thread is provided on the outer peripheral side of the first end of the cover 221, and an internal thread is provided on the inner wall surface of the side of the sleeve 21 away from the sphere 23, so that the cover 221 can be threadedly connected to the inner wall surface of the first installation cavity 211.

[0063] As an example, the ejector rod 222 is a rod-shaped structure with a cylindrical cross-section. An external thread is provided on the outer peripheral side of the ejector rod 222, and an internal thread is provided on the inner wall surface of the second installation cavity 2211, so that the ejector rod 222 can be threadedly connected to the inner wall surface of the second installation cavity 2211. It can be understood that when the ejector rod 222 rotates relative to the cover 221, the distance between the ejector rod 222 and the sphere 23 can be adjusted.

[0064] The second installation cavity 2211 of the cover 221 is used for the ejector rod 222 to extend into the first installation cavity 211 of the sleeve 21, so that the ejector rod 222 can abut against the sphere 23. And the ejector rod 222 is threadedly connected to the inner wall surface of the second installation cavity 2211. When the ejector rod 222 rotates, the pressing force of the ejector rod 222 on the sphere 23 can be adjusted, so as to realize that the sphere 23 can roll relative to the mounting plate 10, thereby realizing driving the battery device 100 to roll relative to the mounting plate 10. In addition, it is also possible to replace the sphere 23 after disassembling the ejector rod 222 and the cover 221.

[0065] Please refer to Figure 7 , according to some embodiments of the present application, the outer diameter of the second end of the cover 221 is greater than the outer diameter of the first end of the cover 221, and the outer diameter of the second end of the cover 221 is greater than the inner diameter of the first installation cavity 211. One end of the sleeve 21 away from the sphere 23 can abut against the second end of the cover 221.

[0066] By setting the outer diameter of the second end of the cover 221 to be greater than the outer diameter of the first end of the cover 221, the first end of the cover 221 can extend into the first installation cavity 211 of the sleeve 21, while the second end of the cover 221 is located outside the sleeve 21, and when the sleeve 21 rotates relative to the cover 221, it can abut against the second end of the cover 221 to play a limiting role and reduce the risk of the sleeve 21 and the cover 221 disengaging.

[0067] Please refer to Figure 7 , according to some embodiments of the present application, a first driving portion 2212 is provided on the outer peripheral surface of the second end of the cover 221, and the first driving portion 2212 is used for cooperating and connecting with a first driving member.

[0068] As an example, the first driving member can be a wrench or a caliper, and the first driving portion 2212 can be at least two planes provided on the outer peripheral side of the second end of the cover 221, and these planes are used for cooperating and connecting with the wrench or the caliper.

[0069] The first driving member can drive the cover 221 to rotate relative to the sleeve 21 through the first driving portion 2212, so as to realize the installation and disassembly of the cover 221 on the sleeve 21.

[0070] Please refer to Figure 8 , according to some embodiments of the present application, the ejector rod 222 includes a first rod body 2221 and a second rod body 2222. The first rod body 2221 is located outside the cover 221, and the second rod body 2222 passes through the second installation cavity 2211 and extends into the first installation cavity 211, and abuts against the sphere 23, wherein the second rod body 2222 has a third installation cavity 2223, and part of the sphere 23 is accommodated in the third installation cavity 2223.

[0071] As an example, the outer diameter of the first rod body 2221 is smaller than the outer diameter of the second rod body 2222. The first rod body 2221 and the second rod body 2222 are integrally connected, and the first rod body 2221 and the second rod body 2222 are coaxially arranged.

[0072] It can be understood that an external thread for threadedly connecting with the sleeve 21 is provided on the outer peripheral side of the second rod body 2222.

[0073] The first rod body 2221 of the ejector rod 222 is located outside the cover 221, and the second rod body 2222 passes through the second installation cavity 2211 of the cover 221 and extends into the second installation cavity 2211 of the sleeve 21, and abuts against the sphere 23 arranged in the sleeve 21, and the second rod body 2222 is threadedly connected with the inner wall surface of the cover 221, so that the position of the second rod body 2222 in the second accommodation cavity can be adjusted, thereby the distance between the second rod body 2222 and the sphere 23 can be adjusted, and the sphere 23 can be freely rotated in the sleeve 21.

[0074] Please refer toFigure 5 , according to some embodiments of the present application, the inner diameter of the third installation cavity 2223 is smaller than the outer diameter of the sphere 23.

[0075] The inner diameter of the third installation cavity 2223 being smaller than the outer diameter of the sphere 23 can not only enable the second rod body 2222 to abut against the sphere 23, but also reduce the risk that the sphere 23 enters the third installation cavity 2223 and cannot roll relative to the mounting plate 10.

[0076] Please refer to Figure 6 , according to some embodiments of the present application, a second driving portion 212 is provided on the outer peripheral surface of the end of the sleeve 21 away from the sphere 23, and the second driving portion 212 is used for cooperating and connecting with a second driving member.

[0077] As an example, the second driving portion 212 can be a hexagonal plane provided on the outer peripheral surface of the end of the sleeve 21 away from the sphere 23, and the second driving member can be a wrench or a caliper.

[0078] The second driving portion 212 is cooperatively connected with the sleeve 21 through the second driving portion 212, so as to facilitate driving the sleeve 21 to rotate relative to the ejector rod assembly 22. The sleeve 21 is threadedly connected to the threaded hole on the hanging plate 101 of the battery device 100. When the sleeve 21 rotates relative to the ejector rod 222, it can drive the battery device 100 to rise or fall. Thus, after the battery device 100 rises relative to the mounting plate 10, by dragging the battery device 100, the sphere 23 can roll relative to the mounting plate 10, and further, the battery device 100 can be quickly disassembled.

[0079] Please refer to Figure 4 and Figure 5 , according to some embodiments of the present application, the sleeve 21 is coaxially arranged with the cover 221 and the ejector rod 222 respectively.

[0080] By coaxially arranging the sleeve 21 with the cover 221 and the ejector rod 222 respectively, the risk of jamming when the sleeve 21 rotates relative to the cover 221 can be reduced, and the risk of jamming when the ejector rod 222 rotates relative to the cover 221 can be reduced, and it helps to improve the installation and disassembly efficiency of the product.

[0081] According to some embodiments of the present application, refer to Figures 1 to 8, this application provides a jacking device 20 for jacking up a battery device 100. The battery device 100 is arranged on a mounting plate 10, and a hanging plate 101 is arranged on the outer peripheral side of the battery device 100.
