In related technologies, these support devices usually include a support base plate and support rods connected to the base plate. These support rods are used to secure multiple containers, ensuring their stability.

[0003] However, current support devices can only fix boxes of a specific size and number, resulting in poor applicability of the support devices. Utility Model Content

[0070] As described in the background section, the support devices in the related technology suffer from poor practicality. The inventors have discovered that this problem arises because the support devices typically consist of two support rods, arranged vertically and connected to each other. The upper support rod is used to fix several boxes, while the lower support rod is used to fix the base plate and several boxes. Furthermore, the height of the support rods is not adjustable, limiting the support device to fixing only a specific number and size of boxes, thus resulting in poor applicability.

[0071] To address the aforementioned technical problems, embodiments of this application provide a support device, stacking housing, battery system, and electrical equipment. The support device includes a support member and a locking member, wherein the support member comprises several support rods. In any two adjacent support rods, the locking member is connected to one support rod and selectively connected to the other support rod, enabling the unlocking or locking of any two adjacent support rods. This configuration allows adjustment of the state of any two adjacent support rods, such as extending or moving one support rod relative to the other. This allows the height of the support member to be adjusted reasonably according to actual needs, enabling the support device to adapt to the stacking requirements of different numbers and sizes of housings. This solves the problem that traditional support devices, due to their fixed height, cannot flexibly adapt to housings of different sizes, thus significantly improving the practicality of the support device.

[0072] To make the above-mentioned objectives, features, and advantages of the embodiments of this application more apparent and understandable, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are merely one partial embodiment of this application, and not the entire embodiment. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0073] Please refer to the attached document. Figure 1 To be continued Figure 3 This application provides a support device adapted to connect with at least two housings 410 to fix the at least two housings 410. It should be understood that the support device can be detachably connected to the at least two housings 410, so that the number of housings 410 can be matched, facilitating quick configuration and adjustment of the support device in different scenarios.

[0074] In addition, each housing 410 may contain individual battery cells; for example, each housing 410 may contain at least two individual battery cells. Other components may also be installed in each housing 410.

[0075] Please refer to the attached document. Figure 4 To be continued Figure 8 The support device includes a support member 100, which includes a plurality of interconnected support rods 110. In any two adjacent support rods 110, one support rod 110 can move relative to the other support rod 110.

[0076] It is important to understand that the structure of the support rod 110 can be chosen in several ways. In one example, each support rod 110 can be a solid rod, with adjacent support rods 110 connected end to end, and adjacent support rods 110 can move relative to each other.

[0077] In another example, each support rod 110 may also be a hollow rod. Exemplarily, each support rod 110 is provided with a receiving chamber 111, wherein the receiving chamber 111 may extend through the support rod 110 along the axial direction of the support rod 110, or may extend through a portion of the support rod 110 along the axial direction of the support rod 110.

[0078] Please refer to the attached document. Figure 4 The support rod 110 is a cylindrical structure with a top opening. In other words, the support rod 110 may include a bottom wall and side walls connected to the bottom wall, with the bottom wall and side walls enclosing a receiving chamber 111. Thus, the bottom wall can provide support for other components disposed within the receiving chamber 111, improving the stability of each support rod 110. It should be noted that the longitudinal cross-sectional shape of the support rod 110 can be a regular shape, for example, a square, a circle, or other shapes. The longitudinal cross-sectional shape of the support rod 110 can also be an irregular shape.

[0079] Any adjacent support rods 110 are nested together, and one support rod 110 at least partially extends out of or retracts into the receiving chamber 111 of the other support rod 110. For example, one support rod 110 is at least partially nested within the receiving chamber 111 of the other support rod 110 (its state can be seen in the appendix). Figure 7 When one of the support rods 110 extends at least partially into the receiving chamber 111 of the other support rod 110 (its state can be seen in the appendix) Figure 8 ).

[0080] This allows for flexible adjustment of the height of the support 100. This design enables the support device to adapt to different heights or spatial layouts without the need to replace support rods 110 of different lengths, reducing usage costs and complexity.

[0081] Please continue to refer to the appendix. Figure 5 and attached Figure 6The support device also includes a locking member 200, which is connected to one of the support rods 110 and selectively connected to the other support rod 110 to unlock or lock any two adjacent support rods 110. In other words, each support rod 110 is connected to a locking member 200.

[0082] It should be noted that the connection between the locking member 200 and the support rod 110 can be understood as follows: in the extension direction parallel to the support rod 110, the locking member 200 is fixedly connected to the support rod 110 to ensure that the locking member 200 can move up and down synchronously with the support rod 110 in its extension direction. In the extension direction perpendicular to the support rod 110, the locking member 200 can move relative to the support rod 110 to allow for selective connection between the locking member 200 and another support rod 110.

[0083] In any two adjacent support rods 110, the extension and fixation of several support rods 110 can be easily achieved by selectively connecting the locking member 200 connected to one support rod 110 to the other support rod 110. The selective connection can be understood as follows: when one support rod 110 needs to move relative to another support rod 110, the locking member 200 is not connected to the other support rod 110, thus releasing the lock on the other support rod 110, allowing one support rod 110 to move axially and at least partially retract into the receiving chamber 111 of the other support rod 110. When one support rod 110 needs to be relatively fixed relative to another support rod 110, the locking member 200 is connected to the other support rod 110 to achieve mutual fixation.

[0084] The locking member 200 is movable in a direction perpendicular to the extension of the support rod 110, thereby unlocking or locking the locking member 200 connected to one support rod 110 with the other support rod 110, and thus controlling the movement or fixation of one support rod 110 relative to the other support rod 110. The extension direction of the support rod 110 is perpendicular to the extension of the support rod 110. Figure 4 In the Z-direction.

[0085] Specifically, in any two adjacent support rods 110, the locking member 200 connected to one of the support rods 110 moves along a direction perpendicular to the extension of the support rod 110 and away from the other support rod 110 to release the fixation on the other support rod 110. Its state can be seen in the appendix. Figure 5Subsequently, one of the support rods 110 can move along its extension direction and at least partially nest within the receiving chamber 111 of another support rod 110 to achieve folding of the support rods 110, thereby facilitating the support device to fix at least two smaller boxes 410 (see attached diagram for its state diagram). Figure 2 and attached Figure 3 ).

[0086] Accordingly, please see the appendix. Figure 6 In any two adjacent support rods 110, when one support rod 110 at least partially extends out of the receiving chamber 111 of the other support rod 110, the locking member 200 moves along a direction perpendicular to the extension of the support rod 110 and toward the other support rod 110 to achieve mutual fixation of the two support rods 110. In this way, the height of the support member 100 can be increased, thereby fixing at least two larger boxes 410 (see attached diagram for their state diagram). Figure 1 ).

[0087] With this configuration, by designing an adjustable-height support member 100, the support device can adapt to the stacking requirements of at least two boxes 410 of different numbers and sizes. This solves the problem that traditional support devices cannot flexibly adapt to at least two boxes 410 of different heights due to their fixed height, thereby significantly improving the practicality of the support device.

[0088] In addition, several support rods 110 can be nested together and folded by unlocking the locking member 200, which not only simplifies the installation process but also saves a lot of storage space, making the support device more convenient in transportation, storage and use.

[0089] In one possible implementation, the locking member 200 includes a locking element 210, which is movably connected to any one of the support rods 110. In two adjacent support rods 110, the locking element 210 connected to one of the support rods 110 is movable in a direction perpendicular to the extension of the support rod 110, so that the two adjacent support rods 110 can be connected or separated.

[0090] For example, when the locking member 210 connected to one of the support rods 110 moves toward the other support rod 110, the locking member 210 can connect with the other support rod 110 to achieve the connection of the two adjacent support rods 110. As another example, when the locking member 210 connected to one of the support rods 110 moves away from the other support rod 110, the locking member 210 can separate from the other support rod 110 to achieve the separation of the two adjacent support rods 110.

[0091] It should be noted that the locking element 210 can be powered by itself, using its own driving force to drive its movement. Alternatively, the locking element 210 can be powered by a drive component of an external device.

[0092] For example, the locking member 200 further includes a driving member 220, which is connected to the locking member 210 and is used to drive the locking member 210 to move along the extension direction perpendicular to the support rod 110, so that two adjacent support rods 110 can be connected or separated.

[0093] The connection design between the driving component 220 and the locking component 210 allows the user to easily operate the locking component 200. Through the driving component 220, the user can easily move the locking component 210 along a direction perpendicular to the extension of the support rod 110, thereby easily achieving height adjustment and locking between the support rods 110. This design greatly simplifies the operation process and improves work efficiency.

[0094] It should be noted that the output end of the drive component 220 can be directly connected to the locking component 210. For example, the drive component 220 is located on the side of the locking component 210 away from the connecting hole 112 and is directly connected to the locking component 210. In this case, the drive component 220 can be a cylinder, and the reciprocating motion of the locking component 210 can be achieved by the extension and retraction motion of the cylinder.

[0095] The output end of the drive member 220 can also be indirectly connected to the locking member 210, and the direction of the output force of the drive member 220 is different from the direction of movement of the locking member 210. For example, please refer to the appendix. Figure 5 Appendix Figure 9 To be continued Figure 12 The drive component 220 is connected to the locking component 210 via the steering component 230.

[0096] Please refer to the attached document. Figure 10 The steering component 230 includes a steering groove 232 and a steering rod 231, with the steering groove 232 disposed within the locking component 210. One end of the steering rod 231 is connected to the driving component 220, and the other end of the steering rod 231 slides within the steering groove 232.

[0097] When the drive member 220 applies a force to the steering rod 231, since the steering rod 231 is relatively fixed in the extension direction parallel to the support rod 110, it can drive the locking member 210 to move in the extension direction perpendicular to the support rod 110, so as to realize the connection or separation of two adjacent support rods 110.

[0098] In one possible implementation, the extending direction of the steering groove 232 is inclined relative to the extending direction of the support rod 110. It should be understood that the extending direction of the steering groove 232 is inclined upwards or downwards relative to the axis of the support rod 110.

[0099] Please refer to the attached document. Figure 10 To facilitate the definition of the function of the steering component 230, the extension direction of the steering groove 232 and the extension direction of the support rod 110 can be set at a preset angle α. The first force F1 applied to the steering rod 231 will generate a vertical component force F3 and a second force F2. Since the locking component 200 is set on the bottom wall of the support rod 110, the locking component 200 will not move downward. Thus, under the action of the second force F2, the locking component 210 moves along the extension direction perpendicular to the support rod 110.

[0100] According to the Pythagorean theorem, F2 = sinα * F1. To increase the second force F2, the preset angle α can be increased as much as possible.

[0101] In this embodiment, the principle of force decomposition is cleverly utilized to realize the conversion of driving force, thereby providing the necessary driving force for the movement of the locking member 210. In addition, the magnitude of the second force F2 can be flexibly controlled by adjusting the size of the preset included angle α. A larger preset included angle α can generate a larger second force F2, thereby enhancing the movement capability of the locking member 210 in the direction perpendicular to the extension of the support rod, making the locking and unlocking process faster and more reliable.

[0102] It should be understood that the drive unit 220 can be directly connected to the steering rod 231 or indirectly. For example, please refer to the appendix. Figure 5 To be continued Figure 8 The locking member 200 also includes a connecting plate 240; the driving member 220 is connected to the steering rod 231 through the connecting plate 240.

[0103] The connecting plate 240, serving as an intermediate connector, ensures a more stable connection between the drive member 220 and the steering member 230, reducing vibration and loosening during transmission. This improves the transmission stability of the locking member 200 and ensures the accuracy and reliability of steering operations. In this embodiment, the size of the connecting plate 240 is smaller than the size of the receiving chamber 111 to facilitate the movement of the locking member 200 along the extension direction perpendicular to the support rod 110.

[0104] In two adjacent support rods 110, the locking member 210 connected to one support rod 110 can be connected to the other support rod 110 by either abutment or snap-fit.

[0105] For example, at least a portion of the support rods 110 are provided with engagement holes 113. For instance, when all the support rods 110 are retracted into the receiving chambers 111 of adjacent support rods 110, and in a direction away from at least two housings 410, each support rod 110, except the innermost support rod 110, is provided with an engagement hole 113. Figure 1 Taking the orientation shown as an example, the topmost support rod 110 may not have a locking hole 113.

[0106] With attachment Figure 5 Taking the orientation shown as an example, the top support rod 110 extends into the receiving chamber 111 of the bottom support rod 110. At this time, the locking protrusion 211 of the locking member 210 inside the top support rod 110 can engage with the engaging hole 113 of the bottom support rod 110, thus achieving a fixed connection between the top and bottom support rods 110. This configuration allows for a fixed connection between two adjacent support rods 110 when they are extended, offering advantages such as simple structure and convenient operation.

[0107] It should be noted that the locking member 200 is movably connected to any support rod 110. This can be understood as the locking member 200 being connected to the outside of the support rod 110 and located between two adjacent support rods 110. Alternatively, it can be understood as the locking member 200 being movably connected to the receiving chamber 111 of any support rod 110.

[0108] For example, please continue to refer to the appendix. Figure 4 To be continued Figure 8 The locking member 200 is movably connected to the receiving chamber 111 of the support rod 110; for example, the locking member 200 is disposed on the bottom wall of the support rod 110, and the bottom wall of the support rod 110 provides support for the locking member 200, thereby improving the stability of the locking member 200.

[0109] At least a portion of the support rod 110 is provided with a connecting hole 112, which connects to the receiving chamber 111, allowing at least a portion of the corresponding locking member 200 to pass through. That is, the locking member 200 can be partially or fully inserted to connect with another support rod 110, thereby fixing adjacent support rods 110 together; or, the locking member 200 can be separated from the other support rod 110 to unlock adjacent support rods 110. It should be noted that since the lowest support rod 110 does not need to extend or retract, the lowest support rod 110 may or may not have a connecting hole 112.

[0110] In one possible implementation, the locking member 210 further includes a locking protrusion 211 extending toward the connecting hole 112, wherein the connecting hole 112 is for the locking protrusion 211 to pass through.

[0111] The locking protrusion 211 is used to connect with the cooperating support rod 110. For example, in two adjacent support rods 110, the locking protrusion 211 of one support rod 110 is used to connect with the other support rod 110. The locking protrusion 211 extends out of the receiving chamber 111 through the connecting hole 112 so that the end of the locking protrusion 211 connects with the cooperating support rod 110, so that the two adjacent support rods 110 are in the extended state. The locking protrusion 211 retracts into the receiving chamber 111 through the connecting hole 112 so that the two adjacent support rods 110 are in the retracted state.

[0112] It should be noted that, in one example, in this embodiment, the driving member 220 drives the locking protrusion 211 to reciprocate. For example, the driving member 220 can not only drive the locking protrusion 211 to extend out of the receiving chamber 111 through the connecting hole 112, but also drive the locking protrusion 211 to retract into the receiving chamber 111 through the connecting hole 112.

[0113] In another example, the drive member 220 is adapted to actuate the locking protrusion 211 through the communication hole 112 to retract into the receiving chamber 111, and to actuate the locking protrusion 211 through the communication hole 112 to extend out of the receiving chamber 111 via other components. Exemplarily, the locking member 200 also includes an elastic member 250, one end of which is connected to the locking member 210, and the other end of which is fixedly connected to the support rod 110 to which it is located.

[0114] Please refer to the attached document. Figure 4 Taking one of the support rods 110 as an example, the locking member 200 is disposed in the receiving chamber 111 of the support rod 110. At this time, the elastic member 250 is disposed on the side of the locking member 210 away from the connecting hole 112, and the other end of the elastic member 250 away from the locking member 210 is welded or engaged with the inner wall of the receiving chamber 111. It should be noted that the elastic member 250 needs to be fixedly connected to the support rod 110 in the extending direction of the support rod 110 so that it can move up and down along the extending direction with the support rod 110.

[0115] With attachment Figure 7 Taking the orientation shown as an example, one of the support rods 110 can be the bottom support rod, and the other support rod 110 can be the top support rod. When the top support rod 110 moves along its extension direction, the locking member 200 disposed in its receiving chamber 111 also moves along its extension direction. When the engagement hole 113 of the bottom support rod 110 and the connecting hole 112 of the top support rod 110 are aligned, the locking member 200 moves in a direction perpendicular to the extension direction, so that the locking protrusion of the locking member 200 is inserted into the corresponding engagement hole and connecting hole, thereby realizing the fixed connection of the two support rods 110.

[0116] In one possible implementation, when the same support rod 110 includes both a connecting hole 112 and a engaging hole 113, the connecting hole 112 and the engaging hole 113 are arranged at intervals along the extending direction of the same support rod 110. (See attached...) Figure 4 Taking the structure shown as an example, the engaging hole 113 is located at the top of the connecting hole 112.

[0117] With attachment Figure 7 and attached Figure 8 Taking the orientation shown as an example, when at least a portion of the top support rod 110 is retracted into the receiving chamber 111 of the bottom support rod 110, the locking protrusion 211 retracts into the receiving chamber 111 to compress the elastic member 250, so that the elastic member 250 is in a compressed state.

[0118] During the upward movement of the top support rod 110, the elastic element 250 remains in a compressed state. When the top support rod 110 moves to the point where its connecting hole 112 aligns with the engaging hole 113 of the bottom support rod 110, the elastic restoring force of the elastic element 250 drives the locking element 210 to move toward the connecting hole 112 and engage in the engaging hole 113 of the bottom support rod 110, so that the top support rod 110 extends out of the receiving chamber 111 of the bottom support rod 110 and is fixed to each other.

[0119] In the embodiments of this application, please refer to the appendix. Figure 2 and attached Figure 7 When all the support rods 110 are retracted into the receiving chamber 111 of the adjacent support rods 110, and in a direction away from at least two housings 410; among the two adjacent support rods 110 except the innermost support rod 110, the bottom of one of the support rods 110 constitutes the drive member 220 of the locking member 200 disposed in the other support rod 110.

[0120] In other words, with attachment Figure 1 Taking the structure shown as an example, in the extension direction of the support rod 110, except for the locking member 200 at the farthest end, the remaining locking members 200 are driven by the support rod 110 located above and adjacent to them. In other words, the driving member 220 of the remaining locking members 200 is formed by the bottom of the support rod 110 located above it.

[0121] It should be noted that in this embodiment, "farthest end" refers to the support rod that is furthest from the starting point or fixed point when the multiple support rods 110 are in an extended state (i.e., each support rod extends outward as far as possible to reach its maximum length or working length). For example, there are 5 support rods 110. From top to bottom, the first support rod 110 constitutes the farthest support rod 110, and the locking member 200 disposed in the receiving chamber 111 of the first support rod 110 constitutes the farthest locking member 200.

[0122] Specifically, from top to bottom, the bottom of the first support rod 110 constitutes the driving member 220 of the locking member 200 located in the receiving chamber 111 of the second support rod 110; the bottom of the second support rod 110 constitutes the driving member 220 of the locking member 200 located in the receiving chamber 111 of the third support rod 110; and so on, the bottom of the fourth support rod 110 constitutes the driving member 220 of the locking member 200 located in the receiving chamber 111 of the fifth support rod 110.

[0123] This design simplifies the structure of the support device, thereby reducing additional connectors and support structures, making the entire device more compact and lightweight.

[0124] Please refer to the attached document. Figure 5 and attached Figure 6 A drive rod is slidably disposed in the receiving chamber 111 of the innermost support rod 110. The drive rod constitutes the drive member 220 of the locking member 200 disposed in the receiving chamber 111 of the innermost support rod 110.

[0125] In other words, please refer to the appendix. Figure 1 Appendix Figure 5 and attached Figure 6 In the extending direction of the support rod 110, a drive rod is slidably provided in the receiving chamber 111 of the farthest support rod 110, and the drive rod constitutes the drive member 220 of the topmost locking member 200.

[0126] To facilitate the description of the movement process of each support rod 110, the three support rods 110 located at the top can be named the first support rod, the second support rod, and the third support rod, and described in detail. When all three support rods 110 at the top are in the extended state, the drive rod moves downward along the axis of the receiving chamber 111 of the first support rod 110. The drive rod drives the locking member 210 to move in a direction perpendicular to the extension of the support rod 110, so that the locking protrusion 211 of the locking member 210 retracts into the receiving chamber 111 and compresses the elastic member 250, thereby unlocking the first and second support rods. Afterward, the first support rod can be controlled to continue moving downward so that the first support rod can be housed in the receiving chamber 111 of the second support rod.

[0127] When the bottom of the first support rod is connected to the connecting plate 240 of the locking member 200 provided on the second support rod, the bottom of the first support rod forms the driving member 220. Thus, the bottom of the first support rod drives the locking member 210 of the locking member 200 provided in the second support rod to move in a direction perpendicular to the extension of the support rod 110, so that the locking protrusion 211 of the locking member 200 provided in the second support rod retracts into the receiving chamber 111 of the second support rod and compresses the elastic member 250, thereby unlocking the second and third support rods. Afterwards, the second support rod can be controlled to continue to move downward so that the second support rod can be housed in the receiving chamber 111 of the third support rod.

[0128] This process is repeated to achieve the retraction of all support rods 110.

[0129] Please refer to the attached document. Figure 14 In one possible implementation, in any two adjacent support rods 110, the locking member 200 is connected to the end of one support rod 110 and located within the receiving chamber 111 of the other support rod 110. That is, the locking member 200 is disposed outside one of the support rods 110, thus eliminating the need for a connecting hole on the support rod 110 and simplifying the structure of the support device.

[0130] It should be noted that, since the locking member 200 is located outside the support rod 110 and connected to the bottom of the support rod 110, the locking member 200 can move up and down along the extension direction of the support rod 110. At the same time, in order to facilitate selective connection between the locking member 200 and its adjacent support rod 110, the locking member 200 can also move relative to the support rod in a direction perpendicular to the extension direction of the support rod.

[0131] Please continue to refer to the appendix. Figure 14 The locking member 200 also includes an elastic element 250. In two adjacent supporting rods 110, one end of the elastic element 250 of the locking member 200 connected to the end of one of the supporting rods 110 is fixedly connected to the corresponding locking member 210, and the other end of the elastic element 250 is connected to the inner wall of the other supporting rod 110. The other end of the elastic element 250 is slidably connected to the inner wall of the other supporting rod 110 to ensure that the locking member 200 can reciprocate along the extension direction of the supporting rod 110 within the receiving chamber 111 of the other supporting rod 110 as one of the supporting rods 110 moves.

[0132] With attachment Figure 14Taking the orientation shown as an example, when the upper support rod 110 moves along its extension direction, the locking member 200 will move upward with it until it moves to the position of the engagement hole 113 of the support rod 110. Under the elastic force of the elastic member 250, the locking member 200 passes through the engagement hole 113 and is fixedly connected to the lower support rod 110.

[0133] In one possible implementation, the bottom of all the support rods 110 constitutes a drive member 220 of the locking member 200 disposed on the support rod 110.

[0134] It should be noted that, since the locking member 210 is fixedly connected to the bottom of the support rod 110, when a force is applied to the locking member 210 in a direction perpendicular to the extension direction of the support rod 110, and in cooperation with the steering member 230, the direction of the force can be changed so that the locking member 210 can move in a direction away from the engaging hole 113.

[0135] To further ensure that the locking member 210 can move toward or away from the engagement hole 113, a support plate may be provided on the side of the locking member 210 away from the end of the support rod 110, and the support plate slides in contact with the inner wall of the receiving chamber 111 of the support rod 110.

[0136] In one possible implementation, when all support rods 110 are retracted into the receiving chambers 111 of adjacent support rods 110, and in a direction away from at least two housings 410, all support rods 110 except the innermost support rod 110 are provided with engagement holes 113. That is, the topmost support rod 110 does not need to be provided with engagement holes 113.

[0137] In two adjacent support rods 110, when at least a portion of one support rod 110 extends into the receiving chamber 111 of the other support rod 110, at least a portion of the locking member 210 connected to one support rod 110 is engaged in the engagement hole 113 of the other support rod 110.

[0138] Please continue to refer to the appendix. Figure 14 The locking member 210 also includes a locking protrusion 211, which extends toward the engaging hole 113; and the engaging hole 113 is adapted for the locking protrusion 211 to pass through. In this embodiment, the area of ​​the locking protrusion 211 is smaller than the area of ​​the rest of the locking member 210, thus reducing the diameter of the engaging hole 113 and ensuring the structural strength of the support rod 110.

[0139] It should also be noted that the locking member 200 also includes a connecting plate 240; in two adjacent support rods 110, one end of the connecting plate 240 is connected to the end of one of the support rods 110 away from the extension direction, and the other end of the connecting plate 240 is connected to the steering rod 231 of the locking member 200.

[0140] The connecting plate 240, serving as an intermediate connector, ensures a more stable connection between the drive member 220 and the steering member 230, reducing vibration and loosening during transmission. This improves the transmission stability of the locking member 200 and ensures the accuracy and reliability of steering operations. In this embodiment, the size of the connecting plate 240 is smaller than the size of the receiving chamber 111 to facilitate the movement of the locking member 200 along the extension direction perpendicular to the support rod 110.

[0141] In one possible implementation, the support member 100 and at least two housings 410 can also be detachably connected. For example, the support device includes fasteners 600, each support rod 110 having a first fixing hole through which the fastener 600 passes. For instance, one fastener 600 passes through two adjacent and opposite first fixing holes and connects to the corresponding housing 410, thereby achieving a detachable connection between the support member 100, the support base 300, and the housings 410.

[0142] The detachable connection between the support member 100 and the housing 410 allows for easy assembly and disassembly of the entire support device. This not only simplifies the installation process but also improves work efficiency, especially when the housing 410 needs to be replaced or repaired, without having to completely remove the entire support device.

[0143] This application also provides a stackable housing 400, including at least two housings 410 and a support device described in any of the above embodiments. The support member 100 of the support device is connected to the at least two housings 410. It should be noted that the number of support rods 110 of the support member 100 in a stretched state depends on the number and size of the at least two housings 410.

[0144] Please refer to the attached document. Figure 2 When at least two boxes 410 include one box 410, all support rods 110 except the bottom support rod 110 are in a retracted state.

[0145] Please refer to the attached document. Figure 3 When at least two boxes 410 are included, from bottom to top, the second support rod 110 extends out of the bottom support rod 110, and the remaining support rods 110 are in a retracted state.

[0146] And so on, please refer to the appendix. Figure 1When at least two boxes 410 include seven boxes 410, the number of support rods 110 is also seven, and all seven support rods 110 are in the extended state.

[0147] With this configuration, the support device can accommodate the stacking requirements of at least two boxes 410 of different numbers and sizes by designing an adjustable height support member 100. This solves the problem that traditional support devices cannot flexibly adapt to stacked boxes 400 of different heights due to their fixed height, thus significantly improving the practicality of the support device.

[0148] In order to achieve a fixed connection between the support member 100 and the housing 410, each housing 410 is provided with a second fixing hole (not shown in the figure); in any two adjacent support rods 110, when one support rod 110 extends at least partially out of the receiving chamber 111 of the other support rod 110, the first fixing holes of the two support rods 110 are aligned with the second fixing holes of the corresponding housing 410.

[0149] With attachment Figure 1 Taking the orientation shown as an example, and from bottom to top, when at least a portion of the second support rod 110 extends beyond the bottommost support rod 110, the first fixing hole of the bottommost support rod 110 (that is, the first support rod 110) aligns with the second fixing hole of the bottommost housing 410; simultaneously, the first fixing hole of the second support rod 110 aligns with the second fixing hole of the second housing 410. Thus, the user only needs to insert the fastener 600 sequentially into the aligned first and second fixing holes and tighten it appropriately to achieve a fixed connection. Similarly, disassembly is also very convenient; simply loosen the fastener 600 to separate the support member 100 from the housing 410.

[0150] It should be noted that in this embodiment, the number of support members 100 can be one or more. For example, at least two support members 100 are provided, spaced apart, and adapted to be connected to at least two housings 410 respectively. By reasonably setting the number and placement of the support members 100, the support requirements in different application scenarios can be met.

[0151] It should be noted that at least two support members 100 can be located on the same side of at least two housings 410. At least two support members 100 can also be located on different sides of at least two housings 410. For example, there are two support members 100, and the two support members 100 are located on opposite sides of at least two housings 410, which improves the stability of at least two housings 410.

[0152] In addition, at least two support members 100 can be connected to the ground or to other support components.

[0153] This application also provides a battery system, which includes the stacked housing 400 described in any of the above embodiments; at least one housing 410 contains a battery. It should be noted that the battery in this embodiment can be a single battery cell or a battery module; for example, the battery may include at least two single battery cells.

[0154] Therefore, the battery system includes all the beneficial effects of the stacked housing 400, which will not be elaborated further in this embodiment.

[0155] It should be noted that the support member 100 of the stacked housing 400 can be directly connected to the ground or connected to other parts. Exemplarily, the battery system also includes a support base 300, to which the support member 100 is connected. Thus, the support base 300 can provide support for the support member 100 and also for at least two housings 410, improving the overall stability of the battery. In this embodiment, the bottom of the support base 300 is also provided with multiple support legs 310.

[0156] At least two support members 100 may have their bottoms connected to the top surface of the support base 300 or to the side surface of the support base 300. For example, the bottoms of at least two support members 100 are connected to the side surface of the support base 300. This avoids occupying the top surface of the support base 300, preventing interference between the support members 100 and the at least two housings 410, thus ensuring that the at least two housings 410 have a larger installation area or more flexible layout options. Furthermore, the connection design between the support members 100 and the side surface of the support base 300 may simplify the assembly and disassembly process of the at least two housings 410 or other components in some cases, as operation can be performed without bypassing or removing the support members 100 located on the top surface, thereby improving maintenance efficiency.

[0157] It should be understood that the support member 100 and the support base 300 can be fixedly connected. For example, the bottom of the support member 100 can be welded to the support base 300 by welding.

[0158] In one possible implementation, the battery also includes a control box 500; the control box 500 is connected to the support device. The control box 500 is positioned opposite the support base 300. Alternatively, the control box 500 is mounted on at least two boxes 410 and connected to the support rod 110 of the support device. That is, the control box 500 is connected to the topmost support rod 110.

[0159] In this embodiment, the control box 500 is combined with the support device, especially the top of the support rod 110, which can maximize the use of vertical space, avoid additional floor space, and make the structure of the entire battery system more compact, which is conducive to saving space and improving space utilization.

[0160] This application also provides an electrical device, including an electrical device and a battery system described in the second aspect, wherein the battery system is electrically connected to the electrical device and provides electrical energy to the electrical device.

[0161] The electrical equipment in this embodiment can be a vehicle, such as a new energy vehicle, which can be a pure electric vehicle, a hybrid electric vehicle, or a range-extended electric vehicle. Correspondingly, the electrical device can be the vehicle's drive mechanism or its control system. Furthermore, the electrical equipment can also be other energy storage devices, such as an energy storage power station.

[0162] Since the electrical device in this embodiment includes the battery described in any of the above embodiments, the electrical device includes the battery structure and beneficial effects, which will not be described in detail here.
