[0058] Figure 3 This is one of the structural schematic diagrams of the battery support device in some embodiments of the present application. Figure 4 This is the second structural schematic diagram of the battery support device of some embodiments of the present application.

[0059] The present application embodiment provides a battery support device 400, such as Figure 3 and Figure 4As shown, the battery support device 400 includes a base 30, a support plate 40 and a connector 50; the support plate 40 is arranged relative to the base 30 along a first direction X, and the support plate 40 is used to support the battery; the connector 50 is arranged between the base 30 and the support plate 40, and the connector 50 is constructed to be able to extend and retract under the action of an external force, so that the base 30 moves relative to the support plate 40 along the first direction X; the first direction X is perpendicular to the surface of the support plate 40 that supports the battery.

[0060] The base 30 can fix the battery support device 400. In addition, the base 30 can be installed on other fixed platforms, or other components can be installed on the base 30, such as components that can realize the lifting function of the battery support device 400. In some embodiments, the base 30 can be sheet-shaped, plate-shaped, column-shaped or truncated cone-shaped, and the specific shape of the base 30 is not limited in this application.

[0061] The support plate 40 may be a plate-like structure, specifically, a regular flat plate, wherein the support plate 40 may be a single-layer flat plate structure, or a composite structure of multiple layers of different materials. The support plate 40 is arranged relative to the base 30 along the first direction X, and it can be understood that there is no direct physical contact between the support plate 40 and the base 30, and the support plate 40 has a projection on the first base 30. In some embodiments, the support plate 40 is parallel to the base 30, and a side surface of the support plate 40 away from the base 30 is used to support the battery, wherein the first direction X is perpendicular to the surface of the support plate 40 supporting the battery.

[0062] The connector 50 is disposed between the base 30 and the support plate 40. Specifically, along the first direction X, the support plate 40, the connector 50 and the base 30 are arranged in sequence, wherein the two ends of the connector 50 can be fixedly connected to the base 30 and the support plate 40, respectively, or can be movably connected to the base 30 and the support plate 40, respectively, or one end is movably connected and the other end is fixedly connected. The connector 50 is constructed to expand and contract under the action of an external force, which can be understood as that, under the action of an external force from the connector 50, wherein the action force can be a contact force or a non-contact force, the connector 50 has the characteristic of being able to change its own size within a certain range, and the connector 50 can return to the original state or close to the original state after the external action force disappears. In some embodiments, the length of the connector 50 changes under the action of the gravity or impact force of the support plate 40 and the object carried, so that the base 30 moves along the first direction X relative to the support plate 40.

[0063] By providing a connector 50 that can be extended and retracted under the action of external force, it is helpful to reduce the impact force when the battery falls into the support plate after being disassembled, and at the same time, the pressure of the battery on the support plate 40 can be dispersed to reduce the situation of excessive local pressure, thereby improving the stability of the battery support and reducing damage to the battery. In addition, by providing a connector 50, the impact of the battery on the support plate 40 when it falls can also be reduced, thereby reducing the probability of damage such as cracks and dents on the support plate 40, and effectively improving the service life of the battery support device 400.

[0064] According to some embodiments of the present application, the connecting member 50 is movably connected to at least one of the base 30 and the support plate 40; the battery support device 400 also includes a first driving unit, which is used to drive one of the base 30 and the support plate 40 to rotate relative to the other along a second direction Y perpendicular to the first direction X.

[0065] The connecting member 50 is movably connected to at least one of the base 30 and the support plate 40. Specifically, there are at least three situations of the movably connected modes of the connecting member 50. First, the connecting member 50 is movably connected to the base 30 and the connecting member 50 is fixedly connected to the support plate 40; second, the connecting member 50 is movably connected to the support plate 40 and the connecting member 50 is fixedly connected to the base 30; third, the connecting member 50 is movably connected to both the base 30 and the support plate 40.

[0066] The first driving unit can realize driving one of the base 30 and the support plate 40 to rotate relative to the other in a second direction Y perpendicular to the first direction X. Specifically, the base 30 and the support plate 40 can realize relative rotation under the driving action of the first driving unit, wherein the direction of rotation is the second direction Y, and the second direction Y is perpendicular to the first direction X. The first driving unit can be a driving device that can realize the rotation function, such as an electric motor, a hydraulic motor or a pneumatic motor.

[0067] By setting a first driving unit to enable one of the base 30 and the support plate 40 to rotate relative to the other along a second direction Y perpendicular to the first direction X, the battery support device 400 is helpful to adjust the position of the support plate in a limited space, and can more flexibly receive and support the battery, thereby improving the convenience and efficiency of operation.

[0068] According to some embodiments of the present application, Figure 3 As shown, the connecting member 50 includes an elastic telescopic element and a roller 51 connected to the elastic telescopic element; wherein the elastic telescopic element is arranged along the first direction X and can undergo elastic telescopic deformation along the first direction X under the action of an external force; the roller 51 is rollingly connected to at least one of the base 30 and the support plate 40.

[0069] An elastic telescopic element is a mechanical element that can undergo elastic deformation when an external force acts on it, thereby achieving a telescopic function. The working principle of the elastic telescopic element is based on Hooke's law, that is, within the elastic limit of the element, the external force it is subjected to is proportional to the amount of elastic deformation generated. In some embodiments, the elastic telescopic element can be a spring, a rubber elastic element, a bellows, etc. Taking the elastic telescopic element as an example, under the action of an external force, the spring can undergo elastic telescopic deformation along its axial direction, wherein the axial direction of the spring is also the first direction X.

[0070] The roller 51 may be composed of a wheel body, a wheel hub, and a roller shaft, wherein the roller shaft may be fixedly connected to the elastic telescopic element. The roller 51 is rollingly connected to at least one of the base 30 and the support plate 40. It can be understood that the roller 51 may be rollingly connected only to the base 30, the roller 51 may be rollingly connected only to the support plate 40, or the roller 51 may be rollingly connected to both the base 30 and the support plate 40.

[0071] By providing a connector 50 including an elastic telescopic element and a roller 51, the energy generated by the impact can be absorbed and consumed, the vibration of the battery support device 400 can be reduced, and the structural wear caused by friction can be reduced, thereby protecting the components of the battery support device 400 from damage and extending the service life.

[0072] According to some embodiments of the present application, Figure 3 As shown, the surfaces of the base 30 and the support plate 40 that are in contact with the roller 51 are provided with a groove 60 for accommodating the roller 51 , the extension path of the groove 60 is a circular loop, and the roller 51 is configured to be able to roll along the extension path of the groove 60 .

[0073] In some embodiments, the groove 60 is formed in the base 30 and the roller 51 is fixedly connected to the support plate 40, or the groove 60 is formed in the support plate 40 and the roller 51 is fixedly connected to the base 30. In other embodiments, the base 30 and the support plate 40 may both be provided with grooves 60 and are correspondingly arranged, wherein the roller 51 is accommodated in the grooves of the base 30 and the support plate 40 and rolls along the extension path of the groove 60.

[0074] The number of rollers 51 may be 3-6, specifically 3, 4, 5 or 6. In some embodiments, the plurality of rollers 51 are arranged at intervals along a circumference with the geometric center of at least one of the base 30 and the support plate 40 as the center. The extension path of the groove 60 is a circular ring line, which can be understood as a circular groove 60 with the geometric center of at least one of the base 30 and the support plate 40 as the center, wherein the roller 51 can roll in the circular groove 60, that is, the roller 51 is configured to roll along the extension path of the groove 60.

[0075] The groove 60 can guide and position the roller 51 , and at the same time, the groove 60 can provide lateral support for the roller 51 to reduce the risk of the roller 51 shaking or tipping over during rolling.

[0076] According to some embodiments of the present application, Figure 3 and Figure 4 As shown, the battery support device 400 further includes a clamping assembly 70 , and the clamping assembly 70 is used to clamp the battery located on the support plate 40 along a third direction Z perpendicular to the first direction X.

[0077] In some examples, the first direction X may be a vertical direction, and the third direction Z may be a horizontal direction.

[0078] The clamping assembly 70 can clamp the battery on the support plate 40 along the third direction Z, wherein the clamping assembly 70 can be any clamping structure, such as a clamping claw or a pair of clamping plates. In some embodiments, the clamping assembly 70 can be configured to move toward or away from each other along the third reverse direction Z to clamp and release the battery.

[0079] The clamping assembly 70 is provided to facilitate clamping and supporting the battery, improve the stability of the battery on the support plate 40, reduce the risk of the battery falling, and thus reduce battery damage.

[0080] According to some embodiments of the present application, Figure 3 and Figure 4 As shown, the clamping assembly 70 includes a first clamping portion 71 and a second clamping portion 72 respectively located on both sides of the base 30 along the third direction Z, the first clamping portion 71 includes a first bottom plate 711 and a first clamping plate 712 protruding from the surface of the first bottom plate 711, the first bottom plate 711 is at least partially located on the side of the first clamping plate 712 facing the support plate 40 along the third direction Z; the second clamping portion 72 includes a second bottom plate 721 and a second clamping plate 722 protruding from the surface of the second bottom plate 721, the second bottom plate 721 is at least partially located on the side of the second clamping plate 722 facing the support plate 40 along the third direction Z; wherein the first clamping plate 712 and the second clamping plate 722 can move relative to each other along the third direction Z to clamp the battery, and the first bottom plate 711 is provided with a first surface 7111 of the first clamping plate 712 and the second bottom plate 721 is provided with a second surface 7211 of the second clamping plate 722 flush.

[0081] The first bottom plate 711 may be partially located on the side of the first clamping plate 712 facing the support plate 40, or may be completely located on the side of the first clamping plate 712 facing the support plate 40; the second bottom plate 721 may be partially located on the side of the second clamping plate 722 facing the support plate 40, or may be completely located on the side of the second clamping plate 722 facing the support plate 40.

[0082] In some embodiments, the structure of the second clamping portion 72 can be the same as or different from that of the first clamping portion 71, as long as the support and support functions of the battery can be realized. The first clamping portion 71 and the second clamping portion 72 are arranged in pairs to jointly realize the clamping and support functions of the battery located on the support plate 40. Specifically, the first clamping plate 712 and the second clamping plate 722 can realize the limitation of the battery along the third direction Z, and the first bottom plate 711 and the second bottom plate 721 can realize the limitation or support of the battery along the first direction X.

[0083] The first surface 7111 of the first base plate 711 provided with the first clamping plate 712 can be the upper surface of the first base plate 711, and the second surface 7211 of the second base plate 721 provided with the second clamping plate 722 can be the upper surface of the second base plate 721. The first surface 7111 and the second surface 7211 are flush, and it can be understood that the first surface 7111 and the second surface 7211 are located on the same plane perpendicular to the first direction X.

[0084] The first clamping portion 71 and the second clamping portion 72 are provided to clamp and support the battery together, which is beneficial to improving the stability of the battery clamping and is compatible with batteries of different specifications. In addition, the first surface 7111 and the second surface 7211 are arranged flush with each other, which is beneficial to improving the stability of the battery clamping.

[0085] Figure 5 This is a simplified schematic diagram of a partial structure of a battery support device according to some embodiments of the present application.

[0086] According to some embodiments of the present application, Figure 5 As shown, the first surface 7111 of the first bottom plate 711 is at a height H1 along the first direction X from the surface of the base 30 facing the support plate 40, and the surface of the support plate 40 supporting the battery when not carrying the battery is at a height H2 from the surface of the base 30 facing the support plate 40, and the following is satisfied: 0

[0087] In some embodiments, the surface of the base 30 facing the support plate 40 , the surface of the support plate 40 supporting the battery, the first surface 7111 , and the second surface 7211 are all parallel planes.

[0088] The vertical height between the first surface 7111 and the surface of the base 30 facing the support plate 40 is H1. When no battery is loaded, the connector is not subjected to the force from the battery (including gravity and impact force). At this time, the vertical height between the surface of the support plate 40 supporting the battery and the surface of the base 30 facing the support plate 40 is H2. H1<H2 means that the surface of the support plate 40 supporting the battery will be higher than the first surface 7111. In this way, when the battery falls into the support plate 40 after being disassembled, the connector will be compressed first, thereby buffering the force brought by the battery. ​

[0089] It should be noted that the first surface 7111 is flush with the second surface 7211 , so that the distance between the second surface 7211 and the surface of the base 30 facing the support plate 40 along the height direction is also H1 .

[0090] In this way, during the falling process of the battery, the battery will first contact the surface of the support plate 40 supporting the battery, and then the connecting member 50 will act as a buffer for the support plate 40 to reduce the risk of damage to the battery. As the battery continues to fall, the battery will continue to contact the first surface 7111 and the second surface 7211 to achieve stable support of the battery by the battery support device 400.

[0091] According to some embodiments of the present application, Figure 5 As shown, when the surface of the support plate 40 supporting the battery is loaded with the battery, the minimum height from the surface of the base 30 facing the support plate 40 is H3, and the following is satisfied: H3≤H1.

[0092] The minimum height H3 of the surface of the support plate 40 supporting the battery from the surface of the base 30 facing the support plate 40 when the battery is loaded is substantially the minimum height of the two when the connector is in a state of maximum compression.

[0093] It can be understood that, without the support of the first surface 7111, when the support plate 40 supports the battery and the connector 50 is compressed, the minimum height of the surface of the support plate 40 supporting the battery from the surface of the base 30 facing the support plate 40 is H3.

[0094] When H3≤H1 is satisfied, it means that when the support plate 40 carries the battery and moves downward under pressure until the surface of the support plate 40 supporting the battery is flush with the first surface 7111, the first surface 7111 can begin to contact the battery and bear the force brought by the battery. Since the first surface 7111 and the second surface 7211 are rigid structures, the battery will no longer cause the support plate 40 to move downward, thereby protecting the connector.

[0095] It should be noted that when the support plate 40 carries the battery and moves downward under pressure, the first clamping plate 712 and the second clamping plate 722 have not yet contacted with and clamped the battery.

[0096] In this way, when the support plate 40 is pressed down by the battery to be flush with the first surface 7111, the first surface 7111 and the second surface 7211 can play a role in assisting in supporting the battery, thereby reducing the risk of elastic failure or material damage of the connector 50, thereby increasing the service life of the battery support device 400.

[0097] According to some embodiments of the present application, Figure 3 and Figure 4As shown, the clamping assembly 70 also includes a second driving part 73 and a first transmission part 74; the second driving part 73 is fixedly connected to the base 30; the first transmission part 74 is respectively connected to the second driving part 73, the first clamping part 71 and the second clamping part 72; wherein the first clamping part 71 and the second clamping part 72 are constructed to move synchronously toward or away from each other along the third direction Z under the drive of the second driving part 73.

[0098] The second driving part 73 can be any driving device, for example, it can be an electric, hydraulic and pneumatic device, and it can also be a handwheel structure with human power as the power source. In some embodiments, the second driving part 73 can be fixedly connected to the base 30 by bolts. The first transmission part 74 is respectively connected to the second driving part 73, the first clamping part 71 and the second clamping part 72 in a transmission manner. It can be understood that the second driving part 73 provides a power source and transmits the power to the first transmission part 74, and the transmission action of the first transmission part 74 makes the first clamping part 71 and the second clamping part 72 move synchronously toward or away from each other along the third direction Z.

[0099] By separately setting up the second driving part 73 and the first transmission part 74, and providing the power source through the second driving part 73 and realizing the clamping effect of the first clamping part 71 and the second clamping part 72 on the battery through the first transmission part 74, the structure is simple, the operation is simple, and the distributed design facilitates the maintenance and replacement of components. In addition, the first clamping part 71 and the second clamping part 72 can realize synchronous movement toward or away from each other, which is conducive to jointly acting on the battery to realize the clamping effect on it, and improve the clamping and support stability.

[0100] Figure 6 This is one of the partial structural schematic diagrams of the battery support device of some embodiments of the present application.

[0101] According to some embodiments of the present application, Figure 6 As shown, the first transmission part 74 includes at least one first transmission screw 741, on which a first screw segment 7411 and a second screw segment 7412 with opposite rotation directions are provided. The first clamping part 71 is transmission connected to the first screw segment 7411, and the second clamping part 72 is transmission connected to the second screw segment 7412.

[0102] The first transmission screw 741 is provided with a first screw segment 7411 and a second screw segment 7412 with opposite rotation directions, and the first screw segment 7411 and the second screw segment 7412 have the same nominal diameter, tooth profile and pitch. In some embodiments, the first screw segment 7411 and the second screw segment 7412 may also have different nominal diameters, tooth profiles and pitches, as long as the first clamping portion 71 driven by the first screw segment 7411 and the second clamping portion 72 driven by the second screw segment 7412 can be synchronously moved toward or away from each other along the third direction Z.

[0103] In some embodiments, Figure 6 As shown, the number of the first transmission screws 741 can be two, and the first thread segments 7411 of the two first transmission screws 741 are both transmission connected to the first clamping portion 71, and the second thread segments 7412 of the two first transmission screws 741 are both transmission connected to the second clamping portion 72.

[0104] By arranging the first screw segment 7411 and the second screw segment 7412 with opposite rotation directions on the first transmission screw 741, the first clamping part 71 and the second clamping part 72 can realize synchronous movement toward or away from each other to clamp or release the battery. The structure is simple and the operation is convenient, and it is also beneficial to improve the stability of the battery support.

[0105] According to some embodiments of the present application, Figure 3 and Figure 4 As shown, the battery support device 400 also includes a lifting assembly 80, which includes a fixed seat 81 and a third driving part 82; the fixed seat 81 is arranged on a side of the base 30 away from the support plate 40, and is spaced apart from the base 30 along the first direction X; the two ends of the third driving part 82 are respectively connected to the fixed seat 81 and the base 30, and drive the base 30 and the support plate 40 to move relative to the fixed seat 81 along the first direction X.

[0106] The fixing seat 81 is used to fix the battery support device 400, and it can fix the battery support device 400 at a preset position. The fixing seat 81 and the base 30 are arranged at intervals along the first direction X, and a third driving part 82 is arranged between the fixing seat 81 and the base 30. The third driving part 82 can be any driving device, for example, it can be an electric, hydraulic and pneumatic device, and it can also be a handwheel structure with human power as the power source. In some embodiments, the length of the third driving part 82 in the first direction X can be extended and retracted so as to realize the movement of the base 30 relative to the fixing seat 81 along the first direction X.

[0107] By providing the lifting assembly 80 , the battery support device 400 can be adapted to batteries of different heights, thereby improving the versatility and compatibility of the device.

[0108] According to some embodiments of the present application, Figure 3 and Figure 4 As shown, the third driving part 82 includes a first lifting driving unit 821 and a second lifting driving unit 822, wherein the first lifting driving unit 821 and the second lifting driving unit 822 are different types of driving units and are respectively used to independently drive the base 30 and the support plate 40 to move relative to the fixed base 81 along the first direction X.

[0109] The first lifting drive unit 821 and the second lifting drive unit 822 are both devices for realizing the lifting movement of an object, which can convert power into displacement in the first direction X. The specific drive unit types of the first lifting drive unit 821 and the second lifting drive unit 822 can be hydraulic, electric, pneumatic, and screw drive, etc. The base 30 and the support plate 40 are independently driven to move relative to the fixed base 81 along the first direction X. It can be understood that the base 30 and the support plate 40 can be driven to move relative to the fixed base 81 along the first direction X only by relying on the first lifting drive unit 821 or only by relying on the second lifting drive unit 822.

[0110] By setting different types of drive units, the weight of the battery can be distributed to different lifting mechanisms to avoid a single lifting unit from bearing too much pressure. In addition, different types of lifting devices have different response speeds and working characteristics, so that a variety of lifting modes can be realized. Through reasonable matching, fast response and efficient operation can be achieved to meet different work needs. In addition, both drive units can work independently, which is conducive to reducing the risk of danger caused by the failure of a single drive unit, conforming to the safety redundancy design, and is conducive to increasing the reliability of the battery support device 400.

[0111] According to some embodiments of the present application, Figure 3 and Figure 4 As shown, the first lifting drive unit 821 includes a lifting cylinder; the second lifting drive unit 822 includes at least one cross-link 8221 and a driving member 8224; the cross-link 8221 includes a first link 8222 and a second link 8223 which are cross-arranged and rotate around a pin shaft located at the intersection respectively; the first link 8222 includes a first end and a second end located at both ends of the intersection respectively, and the second link 8223 includes a third end and a fourth end located at both ends of the intersection respectively, and the first end and the third end are respectively slidably connected to the base 30; the driving member 8224 is respectively connected to the second end and the fourth end to drive the second end and the fourth end to move toward or away from each other.

[0112] like Figure 3 and Figure 4 As shown, the intersection is set at the midpoint of the first connecting rod 8222 and the second connecting rod 8223, and they are cross-arranged with each other through a connecting pin. The first end and the third end are respectively slidably connected to the base 30. In some embodiments, the sliding connection can be achieved through a slider structure. For example, the first end and the third end can be rotated with the slider through a pin shaft, and the first end and the third end can be slidably connected to the base 30 through the sliding action of the slider.

[0113] The number of the cross-linking rods 8221 may be one or more, and the multiple cross-linking rods 8221 may be arranged at intervals along the third direction Z.

[0114] The driving member 8224 can be any driving device, such as an electric, hydraulic, or pneumatic device, or a handwheel structure with human power as the power source. The driving member 8224 is connected to the second end and the fourth end in a transmission manner, so that the second end and the fourth end can be driven to move toward or away from each other, thereby enabling the base 30 and the support plate 40 to move relative to the fixed base 81 along the first direction X, that is, to achieve the lifting of the base 30 and the support plate 40.

[0115] In this way, the cross link 8221 can realize stable lifting of the battery support device 400, which has a simple structure, high strength bearing capacity, strong controllability of movement speed, and is conducive to improving operation accuracy. In addition, the first lifting drive unit 821 and the second lifting drive unit 822 are different types of drive units, which can achieve fast response and efficient operation to meet different work requirements.

[0116] According to some embodiments of the present application, Figure 3 and Figure 4 As shown, a first slide groove is provided on one side surface of the base 30 facing the fixed seat 81, and the first end and the third end are arranged in the first slide groove and can move along the extension direction of the first slide groove; a second slide groove 811 is provided on one side surface of the fixed seat 81 facing the base 30; the driving member 8224 includes a second transmission screw rod 8225, the second transmission screw rod 8225 is arranged in the second slide groove 811, the second end and the fourth end are transmission-connected to the second transmission screw rod 8225, and move toward or away from each other under the drive of the second transmission screw rod 8225.

[0117] In some embodiments, the first chute and the second chute 811 can both be long slot-shaped channels. The first end and the third end are arranged in the first chute and can move along the extension direction of the first chute. It can be understood that the first end and the third end are hinged with different sliders, and the hinged slider is embedded in the first chute so that the first end and the third end can move along the extension direction of the first chute.

[0118] In some embodiments, the second end and the fourth end are hinged to different sliders, the hinged sliders are embedded in the second slide groove 811, and the second transmission screw 8225 is provided with screw segments with opposite rotation directions. The different sliders hinged to the second end and the fourth end are respectively transmission connected to the screw segments with opposite rotation directions, thereby realizing the second end and the fourth end moving toward or away from each other under the drive of the second transmission screw 8225.

[0119] The first slide groove and the second slide groove 811 are conducive to providing a precise motion trajectory for the movement of the first connecting rod 8222 and the second connecting rod 8223, thereby improving the accuracy and repeatability of the movement. In addition, it can also provide stability and reduce friction resistance, thereby improving the stability and reliability of the battery support device 400 during the lifting process.

[0120] Figure 7 This is the second partial structural schematic diagram of the battery support device of some embodiments of the present application.

[0121] According to some embodiments of the present application, Figure 7 As shown, the second lifting drive unit 822 includes a plurality of cross-links 8221 arranged at intervals along the third direction Z; the driving member 8224 includes a plurality of second transmission screws 8225, a rotating motor 8226 and a transmission belt 8227; the plurality of second transmission screws 8225 are arranged on the base 30 and are respectively connected to the plurality of cross-links 8221; the rotating motor 8226 has an output shaft; and the transmission belt 8227 is respectively connected to the output shaft and the plurality of second transmission screws 8225.

[0122] The plurality of cross links 8221 are arranged at intervals along the third direction Z, wherein the number of the cross links 8221 ranges from 2 to 4, specifically, 2, 3 or 4. The rotary motor 8226 outputs power as a power source, and the plurality of rotary screws rotate around their axes through the transmission action of the transmission belt 8227, thereby changing the lengths of the correspondingly connected plurality of cross links 8221 to enable the base 30 and the support plate 40 to move together along the first direction X relative to the fixed base 81.

[0123] The second lifting drive unit 822 is provided with a plurality of cross links 8221, which is conducive to improving the stability and carrying capacity of the battery support device 400, effectively reducing the possibility of battery shaking or tipping, thereby reducing the risk of battery damage. In addition, the use of a transmission belt 8227 to transmit power is further conducive to buffering and shock absorption, thereby improving the reliability and stability of the battery support device 400 during the lifting process.
