Description

Technical Field

[0001] The present invention relates to the technical field of battery maintenance, and in particular to a sodium ion battery energy storage device which is convenient for maintenance of a single battery. Background Art

[0002] Sodium-ion battery is a new type of secondary battery with advantages such as high energy density, fast charging capability and low cost, so it is considered to be a promising development direction for future energy storage systems. Sodium-ion battery is an electrochemical energy storage system based on lithium-ion battery technology, with the positive electrode composed of sodium tetroxide (NaN) and the negative electrode composed of copper metal. Compared with lithium-ion batteries, sodium-ion batteries have higher energy density and faster charging speed, and also have lower production costs.

[0003] Because sodium-ion batteries have higher density and faster charging speed, and are more suitable for low temperature environments, many electric vehicle manufacturers and research institutions are actively researching and developing sodium-ion batteries in order to achieve higher energy density, faster charging speed and lower cost, thereby promoting the advancement of electric vehicle technology.

[0004] A photovoltaic sodium-ion battery energy storage device is disclosed in the patent with the announcement number CN116960549A. Through the setting of the battery installation assembly, two sodium-ion batteries are arranged as a group, which is convenient for taking a single sodium-ion battery. At the same time, through the setting of the device, the wire switch can be automatically disconnected when taking it, to prevent the occurrence of misoperation;

[0005] However, the prior art still has the following defects:

[0006] 1. The structure of the above technology is relatively complex, and it is very inconvenient to take out and install the sodium-ion battery. The traditional placement is mostly vertical combination placement, while it adopts the method of horizontal combination placement of two groups of batteries. When there are fewer battery groups, such a setting will not take up too much space. If there are more battery groups, such a setting will not only take up too much horizontal space, but also be inconvenient for battery maintenance and installation. The horizontal combination placement is not convenient for single-point inspection and replacement, and is not conducive to the dissipation of its heat.

[0007] 2. The two groups of batteries are installed inside the energy storage device, which will cause the battery capacity to accumulate inside the energy storage device and cannot be dissipated in time. In addition, during maintenance, the installation cover needs to be opened to take out the battery. There is no lifting mechanism to lift a single group of batteries, which makes it very troublesome to take and install the battery. Summary of the invention

[0008] In view of the problem in the prior art that sodium ion batteries are inconvenient to remove and install during maintenance, a sodium ion battery energy storage device that is convenient for maintenance of a single battery is proposed.

[0009] The purpose is to lift the battery to be tested by setting the lifting component, so as to facilitate removal, maintenance and installation, and to set a movable pressing component to lift any one or more groups of batteries, thereby improving the efficiency of maintenance.

[0010] The technical solution of the present invention is a sodium ion battery energy storage device that is convenient for repairing a single battery, comprising an energy storage box, partitions arranged at equal intervals inside the energy storage box, battery bodies alternately arranged positively and negatively between the partitions, and a placement bin is formed between the partitions, and also includes a maintenance unit arranged at the bottom of each placement bin;

[0011] The inspection unit includes a lifting component arranged at the bottom of the storage bin, and a pressing component arranged at one side of the lifting component;

[0012] The lifting component is used to lift up the single battery body during maintenance to facilitate maintenance, and the pressing component is used to press down and push the lifting component to lift up the single battery body;

[0013] The lifting component includes a lifting component arranged at the bottom of the storage bin, a supporting component symmetrically arranged at both sides of the bottom of the lifting component, and a resetting component arranged at one side of the bottom of the lifting component;

[0014] The lifting assembly includes a lifting plate arranged at the bottom of the placement bin, hinged seats symmetrically arranged on both sides of the bottom of the lifting plate, a lifting rod arranged on the hinged seat, a pushing rod arranged at the bottom of the two lifting rods, and corresponding movable holes opened on the pushing rods, and a fixing rod arranged in the movable hole, and the bottom of the pushing rod is rotatably connected to the fixing rod, and the bottom of the pushing rod is slidably connected to the bottom of the placement bin.

[0015] By adopting the above technical solution, the maintenance unit can be easily inspected for a single battery body. During the inspection, the pressing component is pressed down to drive the lifting component to rise, thereby lifting the single battery pack placed in the placement bin, so that the maintenance personnel can easily take out the single battery pack for inspection without disassembling the entire battery pack, which is convenient for maintenance personnel to inspect. By setting a separate matching placement bin, it can also improve safety and reduce the possibility of a single battery pack moving in the energy storage box, thereby reducing the occurrence of accidents. In specific operation, when the pressing component is pressed down, it will push the push rod forward, so that the push rod pushes the two lifting rods to move together to one side of the energy storage box through the fixed rod. Since the lifting plate is limited in the placement bin, the two lifting rods will push the lifting plate upward. After the lifting plate is lifted, it will drive the single battery body on its top to move upward, so that the top of the battery body is exposed from the top of the energy storage box, so that it is convenient to take out the battery body during maintenance, and improve the maintenance efficiency.

[0016] Furthermore, the two lifting rods are parallel to each other, and the two lifting rods, the lifting plate and the pushing rod together form a parallelogram.

[0017] By adopting the above technical solution, when the push rod is pushed, the tops of the two mutually parallel lifting rods will synchronously rotate counterclockwise around the hinge seat, so that the lifting plate is lifted. The two lifting rods are stable when lifted, which can improve the supporting strength of the lifting plate after it is lifted upward.

[0018] Furthermore, the support assembly includes support plates symmetrically arranged on both sides of the bottom of the placement bin, the top of the support plate abuts against the lifting plate, and a sliding hole is opened at the bottom of the support plate near the pressing component.

[0019] By adopting the above technical solution, the support assembly is used to support the lifting plate. When the battery body is placed in the placement bin, the battery body squeezes the lifting plate. The lifting plate is supported on two support plates, and provides rotation space for the two lifting rods during lifting, so that the lifting plate can quickly lift the battery body. Since the battery body is heavy, the support of the two support plates can prevent the battery body from directly squeezing the lifting assembly, and avoid damage to the lifting assembly due to long-term squeezing of the battery body when it is placed for a long time, thereby improving the service life of the lifting assembly and the energy storage device.

[0020] Furthermore, the reset assembly includes an extrusion sleeve arranged on one side of the push rod, a reset member arranged in the extrusion sleeve, and an extrusion rod arranged on one side of the reset member, and one side of the extrusion rod is fixedly connected to the support plate, and the other side of the extrusion rod is slidably connected in the extrusion sleeve.

[0021] By adopting the above technical solution, when the push rod is squeezed, the push rod pushes the extrusion sleeve, so that the extrusion rod squeezes the reset part in the extrusion sleeve. The reset part can be a spring. When the pressing part does not push the lifting part, the reset part resets and drives the push rod to reset, so that the two lifting rods can be reset and rotated clockwise, and the lifting plates can be lowered and abutted against the two support plates, so that the battery body can be completely placed in the placement bin and the lifting assembly can be prevented from being crushed.

[0022] Further, the pressing component includes a storage component arranged in a linear array at a side of the bottom of the energy storage box away from the reset component, and a pressing component arranged in the storage component;

[0023] The storage assembly includes a rotating groove opened at the bottom of the energy storage box away from the reset assembly, a linear array of storage grooves opened at the bottom of the energy storage box and located at the top of the rotating groove, and extraction grooves symmetrically opened on both sides of the storage groove.

[0024] By adopting the above technical solution, in the initial state, the pressing assembly is folded in the storage assembly due to the resetting and squeezing action of the resetting assembly. When the battery body is inspected and repaired, one hand rotates and removes the lower pressing plate in the storage slot through the removal slot, so that one end of the lower pressing plate rotates in the rotating slot and squeezes the clamping block, and the clamping block pushes the pushing rod, so that the pushing rod pushes the lifting rod and then raises the lifting plate.

[0025] Furthermore, the pressing assembly includes a sliding rod arranged on the side of the rotating groove close to the outer box wall of the energy storage box, a lower pressing plate arranged on the sliding rod, extrusion surfaces symmetrically opened on both sides of one end of the lower pressing plate, a clamping groove opened at one end of the lower pressing plate, a clamping block arranged on one side of the clamping groove, and the two sides of the clamping block are arc-shaped, the clamping groove is semicircular matching the clamping block, one side of the clamping block is fixedly connected to the push rod, and a concave abutment block is arranged at the top of the lower pressing plate and opposite to the lower edge of the rotating groove.

[0026] By adopting the above technical solution, after the lower pressure plate is rotated and taken out, the wider side of the lower pressure plate (i.e., the extrusion surface) squeezes the clamping block, so that the clamping block drives the push rod to slide into the energy storage box in the sliding hole. When the lower pressure plate is rotated to horizontal, the clamping groove just matches and engages with the clamping block, so that the clamping block can stably resist the push rod, thereby realizing that the lifting plate can stably lift the battery body, making it convenient for maintenance personnel to take out the battery body. The setting of the semicircular clamping groove and the matching clamping block allows the clamping block to just engage with the clamping groove, thereby improving the stability after clamping. And because several groups of battery bodies are arranged in the energy storage box, when one of the groups needs to be inspected, the lower pressing plate can be moved after rotating, so that the lower pressing plate can be moved to the corresponding storage slot position. At this time, the lower pressing plate is rotated again. Since the two sides of the clamping block are in an arc shape, the corresponding clamping block can be squeezed to drive the push rod to contract, and the battery body to be inspected is lifted, so that any one or more groups of battery bodies in the energy storage box can be inspected, and the operation is quick and convenient. When the inspection is completed, the lower pressing plate is rotated upward so that the lifting plate can be reset and lowered. At this time, the lower pressing plate no longer clamps the clamping block. When the clamping block resets and moves, it will push the extrusion surface again, so that the lower pressing plate is automatically stored in the storage slot after rotating, avoiding the lower pressing plate from hindering the installation of the energy storage box, and improving the convenience of storing the lower pressing plate. The arrangement of the abutment block allows the abutment block to be abutted by the upper edge of the rotating groove after the lower pressure plate is moved. At this time, when the lower pressure plate is moved laterally, the maintenance personnel do not need to apply downward pressure in the vertical direction, but only need to apply a lateral pulling force. When the lower pressure plate is pressed down on the next battery body for maintenance, that is, when the abutment block just breaks away from the abutment and enters the position of the next storage groove, the clamping block will squeeze the lower pressure plate at this time, so that the maintenance personnel need to apply downward pressure in the vertical direction of the lower pressure plate, which reminds the maintenance personnel that the lower pressure plate has just reached the position of the storage groove and can be pressed down for lifting operation, thereby avoiding the maintenance personnel from not being able to accurately move to the position of the storage groove when moving the lower pressure plate, allowing the maintenance personnel to operate blindly, thereby improving the accuracy of the positioning of the lower pressure plate after movement, and facilitating the squeezing and folding storage of the lower pressure plate.

[0027] Furthermore, the distance between the two points on the two extrusion surfaces that are farthest apart from each other is greater than the distance between the remaining parts of the lower pressing plate.

[0028] By adopting the above technical solution, that is, the side of the lower pressing plate close to the lifting component is thicker, so that when the lower pressing plate rotates counterclockwise, it can gradually squeeze the clamping block to make it shrink quickly.

[0029] Furthermore, the center of the sliding rod and the center of the clamping block are on the same horizontal line, and the highest point of the extrusion surface abuts against the top of the rotating groove.

[0030] By adopting the above technical solution, the arrangement is such that the extrusion pressure of the clamping block on the lower pressure plate is colinear with the line connecting the centers of the two circles, thereby preventing the extrusion pressure of the lower pressure plate from forming a component force in the vertical direction of the lower pressure plate, causing the deflection of the lower pressure plate, so that the lower pressure plate will not deflect after it is against the clamping block, thereby improving the stability of the lower pressure plate after being clamped to the clamping block.

[0031] Compared with the prior art, the present invention has the following beneficial effects:

[0032] 1. During maintenance, the pressing component is pressed down to drive the lifting component to rise, thereby lifting the single battery pack placed in the storage bin, so that the maintenance personnel can easily take out the single battery pack for maintenance without disassembling the entire battery pack. This is convenient for maintenance personnel to maintain, and by setting up a separate matching placement bin, it can also improve safety and reduce the possibility of a single battery pack moving in the energy storage box, thereby reducing the occurrence of accidents.

[0033] 2. By setting up a parallelogram formed by two lifting rods, a lifting plate and a pushing rod, when the pushing rod is pushed, the tops of the two mutually parallel lifting rods will synchronously rotate counterclockwise around the hinge seat, so that the lifting plate is lifted. The two lifting rods are stable when lifted, which can improve the supporting strength of the lifting plate after it is lifted upward.

[0034] 3. By setting a movable lower pressure plate, the corresponding clamping block can be squeezed to drive the push rod to shrink, and the battery body to be inspected can be lifted, realizing the inspection of any one or more battery bodies in the energy storage box, and the operation is quick and convenient. When the inspection is completed, the lower pressure plate is rotated upward so that the lifting plate can be reset and lowered. When the clamping block is reset and moved, it will push the extrusion surface, so that the lower pressure plate is automatically stored in the storage slot after rotation, avoiding the lower pressure plate from hindering the installation of the energy storage box, and improving the convenience of the lower pressure plate storage.

DETAILED DESCRIPTION

[0046] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0047] Example 1, reference Figure 1-Figure 6, which is the first embodiment of the present invention, provides a sodium ion battery energy storage device that is convenient for repairing a single battery, including an energy storage box 1, partitions 11 installed inside the energy storage box 1 at equal intervals, battery bodies 12 installed alternately front and back between the partitions 11, and a placement bin 13 is formed between the partitions 11, and also includes a maintenance unit installed at the bottom of each placement bin 13; the maintenance unit includes a lifting component installed at the bottom of the placement bin 13, and a pressing component installed on one side of the lifting component; the lifting component is used to lift up a single group of battery bodies 12 during maintenance for easy maintenance, and the pressing component is used to press down and push the lifting component to lift up the single group of battery bodies 12; the lifting component includes a lifting component installed at the placement bin A lifting component 2 at the bottom of 13, a supporting component 3 symmetrically installed on both sides of the bottom of the lifting component 2, and a reset component 4 installed on one side of the bottom of the lifting component 2; the lifting component 2 includes a lifting plate 21 slidably connected to the bottom of the placement bin 13, a hinge seat 22 symmetrically fixedly connected to both sides of the bottom of the lifting plate 21, a lifting rod 23 rotatably connected to the hinge seat 22, a pushing rod 24 rotatably connected to the bottom of the two lifting rods 23, and a movable hole 25 correspondingly opened on the pushing rod 24, and a fixed rod 26 fixedly connected in the movable hole 25, and the bottom of the pushing rod 24 is rotatably connected to the fixed rod 26, and the bottom of the pushing rod 24 is slidably connected to the bottom of the placement bin 13.

[0048] Specifically, the maintenance unit provided can facilitate the maintenance of a single battery body 12. During maintenance, the pressing component is pressed down to drive the lifting component to rise, thereby lifting the single battery pack placed in the placement bin 13, so that maintenance personnel can easily take out the single battery pack for maintenance without disassembling the entire battery pack. This is convenient for maintenance personnel to maintain, and by providing a separate matching placement bin 13, safety can be improved, reducing the possibility of a single battery pack moving in the energy storage box 1, thereby reducing the occurrence of accidents. During specific operation, when the pressing component is pressed down, the pushing rod 24 will be pushed in, so that the pushing rod 24 pushes the two lifting rods 23 to move to one side of the energy storage box 1 through the fixing rod 26. Since the lifting plate 21 is limited in the placement bin 13, the two lifting rods 23 will push the lifting plate 21 upward. After the lifting plate 21 is lifted up, it will drive the single battery body 12 on its top to move upward, so that the top of the battery body 12 is exposed from the top of the energy storage box 1, so that it is convenient to take out the battery body 12 during maintenance, thereby improving the maintenance efficiency.

[0049] Reference Figure 3 , Figure 5 and Figure 6 The two lifting rods 23 are parallel to each other, and the two lifting rods 23, the lifting plate 21 and the pushing rod 24 together form a parallelogram.

[0050] Specifically, the configuration is such that when the push rod 24 is pushed, the tops of the two mutually parallel lifting rods 23 will respectively and synchronously rotate counterclockwise around the hinge seat 22, so that the lifting plate 21 is lifted up. The two lifting rods 23 are stable when lifted up, which can improve the supporting strength of the lifting plate 21 after it is lifted up.

[0051] Reference Figure 1-Figure 7 The support assembly 3 includes support plates 31 symmetrically fixedly connected to both sides of the bottom of the placement bin 13, and the top of the support plate 31 abuts against the lifting plate 21, and a sliding hole 32 is opened at the bottom of the support plate 31 near the side of the pressing component.

[0052] Specifically, the support assembly 3 is used to support the lifting plate 21. When the battery body 12 is placed in the placement compartment 13, the battery body 12 squeezes the lifting plate 21. The lifting plate 21 is supported on two support plates 31, and provides rotation space for the two lifting rods 23 during lifting, so that the lifting plate 21 can quickly lift the battery body 12. Since the battery body 12 is heavy, the support of the two support plates 31 can prevent the battery body 12 from directly squeezing the lifting assembly 2, and avoid damage to the lifting assembly 2 caused by long-term squeezing of the battery body 12 when it is placed for a long time, thereby improving the service life of the lifting assembly 2 and the energy storage device.

[0053] Reference Figure 1-Figure 7 The reset assembly 4 includes an extrusion sleeve 41 fixedly connected to one side of the push rod 24, a reset member 42 fixedly connected in the extrusion sleeve 41, and an extrusion rod 43 fixedly connected to one side of the reset member 42, and one side of the extrusion rod 43 is fixedly connected to the support plate 31, and the other side of the extrusion rod 43 is slidably connected in the extrusion sleeve 41.

[0054] Specifically, when the push rod 24 is squeezed, the push rod 24 pushes the extrusion sleeve 41, so that the extrusion rod 43 squeezes the reset member 42 in the extrusion sleeve 41. The reset member 42 can be a spring. When the pressing component does not push the lifting component, the reset member 42 resets and drives the push rod 24 to reset, so that the two lifting rods 23 can be reset and rotated clockwise, and the lifting plate 21 can be lowered and abutted against the two support plates 31, so that the battery body 12 can be completely placed in the placement bin 13 and the lifting assembly 2 can be prevented from being crushed.

[0055] Example 2, reference Figure 4, which is the second embodiment of the present invention, and this embodiment is different from the first embodiment in that: the pressing component includes a storage assembly 5 installed in a linear array on the bottom side of the energy storage box 1 away from the reset assembly 4, and a pressing assembly 6 installed in the storage assembly 5; the storage assembly 5 includes a rotation groove 51 opened on the bottom side of the energy storage box 1 away from the reset assembly 4, a storage groove 52 opened in a linear array at the bottom of the energy storage box 1 and located at the top of the rotation groove 51, and a removal groove 53 symmetrically opened on both sides of the storage groove 52.

[0056] Specifically, in the initial state, the pressing assembly 6 is folded in the storage assembly 5 by the resetting and squeezing action of the resetting assembly 4. When the battery body 12 is to be inspected, one hand rotates and removes the pressing plate 62 in the storage groove 52 through the taking-out groove 53, so that one end of the pressing plate 62 rotates in the rotating groove 51 and squeezes the clamping block 65. The clamping block 65 pushes the pushing rod 24, so that the pushing rod 24 pushes the lifting rod 23 and then lifts the lifting plate 21.

[0057] Reference Figure 1-Figure 8 The pressing assembly 6 includes a sliding rod 61 fixedly connected to the rotating groove 51 on one side of the outer box wall of the energy storage box 1, a lower pressing plate 62 rotatably and slidably connected to the sliding rod 61, extrusion surfaces 63 symmetrically arranged on both sides of one end of the lower pressing plate 62, a clamping groove 64 arranged at one end of the lower pressing plate 62, a clamping block 65 clamped on one side of the clamping groove 64, and the two sides of the clamping block 65 are arc-shaped, the clamping groove 64 is semicircular matching the clamping block 65, one side of the clamping block 65 is fixedly connected to the push rod 24, and a concave abutment block 66 fixedly connected to the top of the lower pressing plate 62 and opposite to the lower edge of the rotating groove 51.

[0058] Specifically, after the lower pressure plate 62 is rotated and taken out, the wider side of the lower pressure plate 62 (i.e., the extrusion surface 63) squeezes the clamping block 65, so that the clamping block 65 drives the push rod 24 to slide into the energy storage box 1 in the sliding hole 32. When the lower pressure plate 62 is rotated to a horizontal position, the clamping groove 64 just matches and engages with the clamping block 65, so that the clamping block 65 can stably resist the push rod 24, so that the lifting plate 21 can stably lift the battery body 12, which is convenient for maintenance personnel to take out the battery body 12. The setting of the semicircular clamping groove 64 and the matching clamping block 65 enables the clamping block 65 to just be clamped with the clamping groove 64, thereby improving the stability after clamping. And because several groups of battery bodies 12 are arranged in the energy storage box 1, when one of the groups needs to be inspected, the lower pressing plate 62 can be moved after rotating the lower pressing plate 62, so that the lower pressing plate 62 can be moved to the corresponding storage slot 52 position. At this time, the lower pressing plate 62 is rotated again. Since the two sides of the clamping block 65 are in an arc shape, the corresponding clamping block 65 can be squeezed to drive the push rod 24 to contract, and the battery body 12 to be inspected is lifted, so that any one or more groups of battery bodies 12 in the energy storage box 1 can be inspected, and the operation is quick and convenient. When the inspection is completed, the lower pressing plate 62 is rotated upward so that the lifting plate 21 can be reset and lowered. At this time, the lower pressing plate 62 no longer clamps the clamping block 65. When the clamping block 65 resets and moves, it will push the extrusion surface 63 again, so that the lower pressing plate 62 is automatically stored in the storage slot 52 after rotating, avoiding the lower pressing plate 62 from hindering the installation of the energy storage box 1, and improving the convenience of storing the lower pressing plate 62. The arrangement of the abutment block 66 allows the abutment block 66 to be abutted by the upper edge of the rotating groove 51 after the lower pressure plate 62 is moved. At this time, when the lower pressure plate 62 is moved laterally, the maintenance personnel do not need to apply downward pressure in the vertical direction, but only need to apply a lateral pulling force. When the lower pressure plate 62 is pressed down on the next battery body 12 for maintenance, that is, when the abutment block 66 just breaks away from the abutment and enters the position of the next storage groove 52, at this time, the clamping block 65 will squeeze the lower pressure plate 62, so that the maintenance personnel need to apply downward pressure in the vertical direction of the lower pressure plate 62, that is, to remind the maintenance personnel that the lower pressure plate 62 has just reached the position of the storage groove 52 and can be pressed down for lifting operation, so as to avoid the maintenance personnel being unable to accurately move to the position of the storage groove 52 when moving the lower pressure plate 62, so that the maintenance personnel can operate blindly, thereby improving the accuracy of the positioning of the lower pressure plate 62 after movement, and facilitating the squeezing and folding storage of the lower pressure plate 62.

[0059] Reference Figure 8-Figure 9 , the distance between the two farthest points on the two extrusion surfaces 63 is greater than the distance between the remaining parts of the lower pressing plate 62.

[0060] Specifically, the side of the lower pressing plate 62 close to the lifting component is thicker, so that when the lower pressing plate 62 rotates counterclockwise, it can gradually squeeze the clamping block 65 to make it shrink quickly.

[0061] Reference Fig. 9 The center of the sliding rod 61 and the center of the clamping block 65 are on the same horizontal line, and the highest point of the extrusion surface 63 abuts against the top of the rotating groove 51.

[0062] Specifically, the arrangement is such that the squeezing force of the clamping block 65 on the lower pressing plate 62 is in line with the line connecting the centers of the two circles, so as to avoid the squeezing force of the lower pressing plate 62 forming a component force in the vertical direction of the lower pressing plate 62, causing the deflection of the lower pressing plate 62, so that the lower pressing plate 62 will not deflect after abutting against the clamping block 65, thereby improving the stability of the lower pressing plate 62 after clamping the clamping block 65. The rest of the structure is the same as that of the first embodiment.

[0063] In summary, the working principle of the present invention is as follows: when inspecting any one or more battery bodies 12 in the energy storage box 1, the lower pressure plate 62 is pressed down and rotated so that the extrusion surface 63 squeezes and pushes the clamping block 65. After the clamping block 65 is squeezed, it drives the push rod 24 to shrink into the placement chamber 13. At this time, the two lifting rods 23 will push the lifting plate 21 upward, so that the lifting plate 21 can lift the battery body 12. When the lower pressure plate 62 is rotated to the clamping groove 64 and the clamping block 65, the lifting plate 21 is stably lifted up, so that the battery body 12 can be taken out easily. After the inspection, the lower pressure plate 62 can be rotated clockwise to realize the folding and storage of the lower pressure plate 62 and the reset and downward movement of the lifting plate 21, thereby realizing the installation of the battery body 12.

[0064] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, which should all be included in the scope of the claims of the present invention.
