Description

Technical Field

[0001] This utility model relates to the technical field of battery box installation equipment, and more specifically, to a battery box and a power battery having the same. Background Technology

[0002] Currently, chemical energy storage products are mainly based on lithium battery energy storage products, and the battery box is a very important unit in lithium battery energy storage products. A battery box consisting of 280Ah (or 314Ah) batteries (1P48S or 1P52S) weighs about 300kg, which is no longer feasible for a single person to operate and install manually. To improve energy density, the industry is continuously increasing the capacity of individual batteries. Some companies have already launched products with single-cell capacities exceeding 500Ah. This increase in battery capacity has correspondingly increased the weight of the battery box, placing higher demands on its structure. The battery box must be designed to facilitate installation during production and also allow for disassembly and maintenance after sales.

[0003] However, judging from most products on the market, the structure of the battery box is mainly designed to facilitate installation at the production end. The battery box is installed on the battery rack using a forklift or robotic arm, but the convenience of maintenance at the after-sales end is not taken into consideration. When the battery box has a problem and needs to be repaired or replaced, it is difficult to pull the battery box out of the battery rack, which can easily cause the battery box to fall and injure people or even affect the personal safety of after-sales personnel.

[0004] There is currently no effective solution to the above problems. Utility Model Content

[0005] The main objective of this invention is to provide a battery box and a power battery thereon, in order to solve the technical problem that disassembling the battery box can easily lead to damage to the structural safety of the battery box.

[0006] To achieve the above objectives, according to one aspect of the present invention, a battery box is provided, including a box body, with at least one support component disposed at the bottom of the box body. The support component includes: a support base connected to the bottom of the box body, the support base having an internal receiving cavity; an adjustment component extending along the length direction of the support base and connected to the support base, at least a portion of the adjustment component being located within the receiving cavity; and a sliding component including a connecting shaft and a bearing, the bearing being sleeved on the connecting shaft and rotatably disposed relative to the connecting shaft, the connecting shaft passing through the receiving cavity along the width direction of the support base, and a portion of the connecting shaft passing through the adjustment component. The bearing has a receiving position at least partially housed within the receiving cavity and a working position protruding from the bottom surface of the support base. The adjustment component rotates along a preset direction, causing the adjustment component to move the bearing to the receiving position and the working position.

[0007] Furthermore, when the bearing is in the stowed position, the outer edge of the bearing is flush with the bottom surface of the support.

[0008] Furthermore, the adjustment assembly includes: a rack, a portion of which is disposed within the receiving cavity and extends along the length of the support, and another portion of which protrudes from one end of the support, with a shaft passing through the rack; and an adjustment member, which is connected to the portion of the rack protruding from the support. Rotating the adjustment member in a first direction allows the rack to drive the bearing to the retracted position, and rotating the adjustment member in a second direction allows the rack to drive the bearing to the working position.

[0009] Furthermore, a first elongated hole is provided on the rack, and the connecting shaft passes through the first elongated hole. The maximum diameter of the connecting shaft is smaller than the length of the longest side of the first elongated hole.

[0010] Furthermore, a second elongated hole is provided on the opposite side wall of the receiving cavity. The connecting shaft passes through the first elongated hole and the second elongated hole along the length direction perpendicular to the toothed rod. The maximum diameter of the connecting shaft is smaller than the length of the longest side of the second elongated hole. The first elongated hole is offset from the farthest end of the toothed rod, and the second elongated hole is offset from the farthest end of the toothed rod.

[0011] Furthermore, rotating the operating adjustment component in the first direction allows the connecting shaft to move upward along the trajectory of the second elongated hole, thereby causing the bearing to be in the storage position. Rotating the operating adjustment component in the second direction allows the connecting shaft to move downward along the trajectory of the second elongated hole, thereby causing the bearing to be in the working position.

[0012] Furthermore, the bottom of the cavity is provided with an opening, through which the connecting shaft drives the bearing to move to the storage position and the working position.

[0013] Furthermore, there are multiple sliding components, which are arranged in pairs at the bottom of the housing and connected to the support base.

[0014] Furthermore, the adjustment components are in two sets, which are symmetrically arranged at the bottom of the housing and connected to the support base.

[0015] To achieve the above objectives, according to one aspect of the present invention, a power battery is provided, including a battery box, wherein the battery box is any of the battery boxes described in the above embodiments.

[0016] The present invention utilizes a support base with an internal cavity to provide space for the sliding component and serve as a fulcrum for operation. An adjustment component extends along the length of the support base, and a bearing is connected to the adjustment component inside the support base via a connecting shaft. The bearing is rotatably mounted on the connecting shaft. Adjusting the component in a preset direction allows the bearing to be positioned between a storage position and a working position. This switching between storage and working positions allows the battery box to flexibly adapt to different spatial conditions during installation and disassembly, changing the contact between the box and the battery rack from surface contact to point or line contact. This significantly reduces friction, prevents damage to the paint or plating on the battery box and battery rack during installation, reduces the risk of corrosion, and thus extends the service life of the battery box and battery rack, improving the overall reliability of the product. The battery box can be lifted and placed manually using the adjustment component, significantly improving ease of operation in confined spaces or without specialized tools. This application solves the technical problem in the prior art where the battery box is difficult to disassemble, leading to compromised structural safety. Attached Figure Description

[0047] Combination Figures 1 to 12 As shown, according to a specific embodiment of this application, a battery box and a power battery having the same are provided.

[0048] Specifically, such as Figure 1 , Figure 2As shown, the battery box includes a box body 7, and at least one support component is provided at the bottom of the box body 7. The support component includes a support base 3, an adjustment component, and a sliding component. The support base 3 is connected to the bottom of the box body 7 and has a receiving cavity inside. The adjustment component extends along the length direction of the support base 3 and is connected to the support base 3. At least a portion of the adjustment component is located within the receiving cavity. The sliding component includes a connecting shaft 1 and a bearing 2. The bearing 2 is sleeved on the connecting shaft 1 and is rotatably arranged relative to the connecting shaft 1. The connecting shaft 1 passes through the receiving cavity along the width direction of the support base 3, and a portion of the connecting shaft 1 passes through the adjustment component. The bearing 2 has a storage position that is at least partially housed within the receiving cavity and a working position that protrudes from the bottom surface of the support base 3. The adjustment component rotates in a preset direction, which can cause the adjustment component to move the bearing 2 to the storage position and the working position.

[0049] Applying the technical solution of this utility model, the support base 3 has an internal cavity to provide space for the sliding component and also serves as a fulcrum for operation. The adjustment component extends along the length of the support base 3. The bearing 2 is connected to the adjustment component inside the support base 3 via a connecting shaft 1. The bearing is rotatably mounted on the shaft. Adjusting the adjustment component in a preset direction allows the adjustment component to move the bearing to the storage position and the working position. The switching between the storage position and the working position of the bearing 2 allows the battery box to flexibly adapt to different spatial conditions during installation and disassembly, changing the contact between the box body 7 and the battery rack from surface contact to point contact or line contact, greatly reducing friction and avoiding damage to the paint film or plating on the surface of the battery box and battery rack during installation, reducing the risk of corrosion, thereby extending the service life of the battery box and battery rack and improving the overall reliability of the product. The battery box can be lifted and placed by manual operation of the adjustment component, significantly improving the ease of operation in narrow spaces or without professional tools. This application solves the technical problem in the prior art where the battery box is not easy to disassemble, resulting in damage to the structural safety of the battery box.

[0050] Specifically, when bearing 2 is in its retracted position, its outer edge is flush with the bottom surface of support 3. When the battery box is fully installed on the support assembly, the outer edge of bearing 2 is adjusted to be at the same level as the bottom surface of support 3. This means that bearing 2 does not protrude from the bottom of the battery box, but is fully or nearly fully retracted into the receiving cavity of support 3. Support 3, as a stable base, provides housing space for bearing 2, allowing it to switch between the retracted and operating positions.

[0051] When the battery box is mounted on the support assembly, the retracted position of bearing 2 ensures non-contact with the surface of the support structure, avoiding additional friction caused by the protrusion of bearing 2 when pushing or pulling the battery box in. This protects the surface coatings of the battery box and the support assembly, such as paint or plating, reducing damage caused by friction and the risk of long-term corrosion. With bearing 2 in the retracted position, the battery box rests directly on the top surface of the support base 3, increasing the contact area and thus increasing the static friction between the battery box and the support assembly. This contact mode helps maintain the positional stability of the battery box during transportation or in vibration environments, avoiding slippage or vibration that might be caused by the protrusion of bearing 2.

[0052] The flush design of the bearing 2 and the bottom surface of the support base 3 simplifies the initial positioning and subsequent alignment process of the battery box. During battery box installation, the operator only needs to observe the alignment of the support base 3 with the support components, without the need to adjust the position of the bearing 2, making the installation process more efficient and simplified. When folded, the bearing 2 does not occupy additional space at the bottom of the battery box, meaning that the battery box can be designed to be more compact, which is beneficial for efficiently arranging the energy storage system in a limited space, and also contributes to the overall lightweight design of the battery box.

[0053] Furthermore, such as Figure 3-5 The adjustment assembly includes a rack 4 and an adjusting member 6. Part of the rack 4 is disposed within the receiving cavity, extending along the length of the support base 3. Another part of the rack 4 protrudes from one end of the support base 3, and a connecting shaft 1 passes through the rack 4. The adjusting member 6 is connected to the protruding portion of the rack 4 from the support base 3. Rotating the adjusting member 6 in a first direction moves the rack 4, causing the bearing 2 to be in a retracted position. Rotating the adjusting member 6 in a second direction moves the rack 4, causing the bearing 2 to be in a working position. Through the linear movement of the rack 4 and the rotational control of the adjusting member 6, the bearing 2 can be switched between the retracted and working positions. This simple mechanical structure achieves frictional control during the installation and disassembly of the battery box, improving operational safety and convenience.

[0054] The rack 4 is placed in the receiving cavity inside the support base 3 and extends along the length of the support base 3. In the design, one end of the rack 4 will protrude outside the support base 3 so as to connect with the adjusting member 6. The adjusting member 6 is connected and fixed to the rack 4 by threads or other connection methods, so that operating the adjusting member 6 can drive the rack 4 to move axially.

[0055] When it is necessary to remove the housing 7 from the support assembly, the operator uses a wrench or other tool to rotate the adjusting member 6 in a first direction (usually clockwise or counterclockwise, depending on the design). This rotational force is converted into axial force, which, through the threaded connection between the adjusting member 6 and the rack 4, pushes the rack 4 to move along its length (i.e., forward or backward), thereby causing the bearing 2 to move upward, from a storage position flush with the bottom surface of the support base 3 to a working position protruding from the bottom surface of the support base 3. At this point, the bearing 2 assumes the task of supporting the weight of the housing 7. Through its point or line contact with the support assembly, it reduces friction with the support assembly, allowing the housing to be pulled out more easily by hand or small tools without the need for large machinery such as forklifts or robotic arms. Conversely, when the battery box needs to be installed onto the support structure, the operator rotates the adjusting component 6 in the second direction (opposite to the first direction). The rack 4 moves in the opposite direction under the action of the thread, causing the bearing 2 to move downwards to a storage position flush with the bottom surface of the support base 3. At this point, the battery box 7 is placed directly on the support base 3, increasing the contact area and improving installation stability and safety. It also reduces damage to the surface coating of the battery box and support components. This design not only significantly improves the ease of operation during battery box installation and disassembly, reducing labor costs, but also protects the surface coating by reducing frictional damage, delaying the corrosion process, and thus extending the service life of the battery box and support structure. Furthermore, the introduction of this adjustment mechanism optimizes space utilization, making the support component structure more compact and adaptable to installation requirements in confined spaces, demonstrating the flexibility and practicality of the design.

[0056] Specifically, the rack 4 has a first elongated hole 8, and the connecting shaft 1 passes through the first elongated hole 8. The maximum diameter of the connecting shaft 1 is smaller than the length of the longest side of the first elongated hole 8. The length of the longest side of the first elongated hole 8 is greater than the maximum diameter of the connecting shaft 1, allowing the connecting shaft 1 a certain amount of movement within the first elongated hole 8. The shape and size design of the first elongated hole 8 ensures that the connecting shaft 1 will not interfere with the rack 4 when rotating. At the same time, when the rack 4 moves axially, the connecting shaft 1 can slide along the longest side within the first elongated hole 8 without falling off. This provides a guarantee for the stability of the bearing 2 and avoids failures or accidents caused by the connecting shaft 1 falling off during operation. Simultaneously, this design also ensures that the bearing 2 can be accurately and stably positioned when moving from the storage position to the working position, reducing installation difficulties caused by bearing 2 positional misalignment.

[0057] In this embodiment, as Figure 10 As shown, multiple first elongated holes 8 are provided along the length of the toothed rod 4.

[0058] Specifically, a second elongated hole 10 is provided on the opposite sidewall of the receiving cavity. The connecting shaft 1 passes through the first elongated hole 8 and the second elongated hole 10 along the length direction perpendicular to the rack 4. The maximum diameter of the connecting shaft 1 is smaller than the length of the longest side of the second elongated hole 10. The first elongated hole 8 is offset from the farthest end of the rack 4, and the second elongated hole 10 is offset from the farthest end of the rack 4. Through the cooperation between the second elongated hole 10 and the first elongated hole 8, and the control of the movement trajectory of the connecting shaft 1, the bearing 2 can be precisely switched between the storage position and the working position.

[0059] like Figure 9 As shown, the second elongated hole 10 is located on the opposite sidewall of the receiving cavity. Its shape is designed as an elongated hole, positioned along an axis perpendicular to the length of the rack 4, for the connecting shaft 1 to pass through. The longest side of the second elongated hole 10 is longer than the maximum diameter of the connecting shaft 1, allowing the connecting shaft 1 a certain degree of axial movement within the second elongated hole 10. The first elongated hole 8 and the second elongated hole 10 are misaligned at the farthest end of the rack 4, meaning their centerlines are not perfectly aligned. When the operator moves the rack 4 along its length using the adjusting member 6, the connecting shaft 1 slides smoothly within the first elongated hole 8 and the second elongated hole 10. This misalignment ensures that the bearing 2 does not encounter structural jamming points during movement, enabling the bearing 2 to smoothly move from a storage position flush with the bottom surface of the support base 3 to a working position protruding from the bottom surface of the support base 3. By setting the first elongated hole 8 and the second elongated hole 10 in a staggered manner, this utility model not only ensures the smooth movement of the bearing 2, but also optimizes the structural layout of the support assembly, reduces the structural complexity, and makes the entire support assembly more compact, adapting to the installation requirements of narrow spaces, thereby improving the applicability of the battery box.

[0060] Specifically, rotating the adjusting member 6 in the first direction moves the connecting shaft 1 upward along the trajectory of the second elongated hole 10, thereby causing the bearing 2 to be in the storage position. Rotating the adjusting member 6 in the second direction moves the connecting shaft 1 downward along the trajectory of the second elongated hole 10, thereby causing the bearing 2 to be in the working position. By controlling the movement of the connecting shaft 1 within the second elongated hole 10 through the rotation direction of the adjusting member 6, the precise position change of the bearing 2 can be achieved. This mechanism not only simplifies the installation and disassembly of the battery box, ensuring safe and efficient operation, but also effectively reduces frictional damage between the battery box and the support components.

[0061] like Figure 11 , Figure 12As shown, the operator rotates the adjusting component 6 using a wrench or other tools. When the adjusting component 6 rotates in the first direction, it generates axial thrust through its threaded connection with the rack 4, pushing the rack 4 backward along its length. This backward movement of the rack 4 causes the connecting shaft 1 to move downward within the first elongated hole 8 and the second elongated hole 10, ultimately placing the bearing 2 in a recessed position flush with the bottom surface of the support base 3. When the adjusting component 6 rotates in the opposite second direction, the rack 4 moves forward, and the connecting shaft 1 moves upward under the guidance of the trajectory in the second elongated hole 10, causing the bearing 2 to rise to a working position protruding from the bottom surface of the support base 3. The design of the second elongated hole 10 provides a precise movement trajectory for the connecting shaft 1, ensuring the smoothness and accuracy of the bearing 2 throughout its movement from the working position to the recessed position, or vice versa. This design avoids potential jamming or unnecessary friction during the movement of the bearing 2, thereby extending the service life of both the bearing 2 and the connecting shaft 1. The bearing 2 can be switched between its storage and working positions simply by rotating the adjustment component 6. This greatly simplifies the installation and disassembly of the battery box, reduces reliance on specialized tools, and improves operational efficiency. At the same time, the smooth movement and accurate positioning of the bearing 2 reduce uncertainties and risks during operation, thus enhancing overall operational safety.

[0062] Specifically, the bottom of the cavity has an opening 9, through which the connecting shaft 1 drives the bearing 2 to move to the storage position and the working position. The opening 9 not only provides a channel for the bearing 2 to move, but also ensures smoothness and safety during the movement.

[0063] The design of opening 9 needs to take into account the size of bearing 2, the movement trajectory of connecting shaft 1, and the strength and stability of the overall structure. Bearing 2 is fitted onto connecting shaft 1, and the outer diameter of bearing 2 is smaller than the width of opening 9, ensuring that bearing 2 can move freely within the allowable range of opening 9.

[0064] The opening 9 serves as the path for the movement of the bearing 2. When the connecting shaft 1 moves along the trajectory of the second elongated hole 10 under the drive of the adjusting member 6, the bearing 2 moves vertically within the receiving cavity and at the opening 9. The movement from the storage position to the working position means that the bearing 2 starts from a state flush with the bottom surface of the support base 3 and gradually protrudes outward through the opening 9 until it reaches the predetermined working height. At this point, the bearing 2 can bear the weight of the housing 7 and reduce friction with the support structure. Conversely, the return from the working position to the storage position is the process of the bearing 2 gradually retracting to be flush with the bottom surface of the support base 3. At this point, the housing 7 is placed directly on the support base 3, increasing the contact area and improving the stability of the installation.

[0065] Specifically, multiple sliding components are arranged in pairs at the bottom of the housing 7 and connected to the support base 3. The use of multiple sliding components ensures uniform force distribution and stable movement of the battery box during installation and disassembly. This improves the operational stability and safety of the battery box during installation and disassembly, reducing the risk of device damage and battery box displacement caused by excessive force at a single point.

[0066] The sliding components are arranged in pairs at the bottom of the housing 7, meaning that each corner or side of the housing 7 has a corresponding sliding component. This layout ensures that the housing 7 can be evenly stressed when the battery box is pushed into or pulled out of the support base 3, avoiding tilting, jamming, or damage that may be caused by uneven local stress. The paired sliding components ensure that the four corners or at least the symmetrical sides of the battery box receive balanced support during placement and movement on the support base 3, avoiding excessive stress on a single point, thereby improving the stability and safety of the battery box.

[0067] By adjusting component 6, the position of bearing 2 can be changed from surface contact in the storage position to point or line contact in the working position. This significantly reduces the friction between the housing 7 and the support 3, preventing damage to the surface coating during movement, reducing maintenance costs, and extending the component's lifespan. The symmetrical distribution and adjustment mechanism of the sliding components allow the operator to quickly switch bearing 2 from the storage position to the working position simply by rotating component 6. This makes the battery box loading and unloading process more convenient and efficient, even in confined spaces, allowing for easy manual operation.

[0068] Specifically, there are two sets of adjustment components, symmetrically arranged at the bottom of the housing 7 and connected to the support base 3. Through these two symmetrically arranged adjustment components, the battery box of this invention not only achieves a smooth transition between the bearing 2's storage and working positions, but also ensures the balance of the battery box during lifting, reducing frictional damage during operation and improving operational safety and efficiency.

[0069] Specifically, the adjustment components are designed in two sets, symmetrically arranged at the bottom of the housing 7 and connected to the support base 3. This design further optimizes the convenience and stability of battery box installation and disassembly. Each adjustment component includes a gear 4 and an adjustment element 6. The gear 4 has a first elongated hole 8, through which the connecting shaft 1 passes and the second elongated hole 10 on the side wall of the support base 3. The bearing 2 is sleeved on the connecting shaft 1 and can move to the working position or the storage position through the opening 9 at the bottom of the receiving cavity. The two sets of adjustment components are installed symmetrically on both sides of the bottom of the housing 7 and connected to the corresponding positions of the support base 3. This symmetrical design ensures the balance of the battery box during movement and avoids tilting or instability caused by unilateral force.

[0070] The rotation direction of the adjusting component 6 (such as a nut) controls the position change of the bearing 2. When the adjusting component 6 is rotated in the first direction, the bearings 2 of both sets of adjusting components simultaneously rise to the working position. The contact point or line between the bearings and the support frame reduces friction, allowing the housing 7 to be easily pulled out or pushed in from the support base 3. When the adjusting component 6 is rotated in the second direction, the bearings 2 simultaneously descend to the storage position. At this time, the housing 7 is in direct contact with the support base 3, increasing friction and ensuring the stability of the battery box during transportation and use. The two symmetrically arranged adjusting components allow the operator to control the synchronous movement of the bearings 2 on both sides of the housing 7 by operating from only one side, simplifying the operation process and improving efficiency. Simultaneously, the symmetrical design ensures balance during movement, avoiding operational risks caused by uneven force on one side and enhancing overall safety.

[0071] The symmetrical arrangement of the adjustment components also optimizes the space utilization at the bottom of the housing 7. Compared to adjustment components set on one side, the symmetrical design ensures functionality and stability while reducing the space occupied inside the housing, which helps to increase the overall capacity of the battery box, thereby improving the energy density and performance of the product.

[0072] It needs to be further explained that, such as Figure 8 As shown, the connecting shaft 1 includes: a shaft body, one end of which is provided with a shaft flange 11, the radial dimension of which is greater than the radial dimension of the second elongated hole 10, and the shaft flange 11 abuts against one side of the support base 3; a bearing limiting platform 12, one end of which abuts against the shaft flange 11, and when the connecting shaft 1 is connected to the bearing 2, the other end of the bearing limiting platform 12 abuts against the bearing 2, and the radial dimension of the bearing limiting platform 12 is greater than the inner diameter of the bearing 2.

[0073] A shaft flange 11 is located at one end of the shaft body and has a larger radial dimension, exceeding the radial dimension of the second elongated bore 10. This flange provides positioning and stopping during the movement of the connecting shaft 1, preventing the connecting shaft 1 from completely disengaging from the support 3. The shaft flange 11 abuts against one side of the support 3, forming a boundary restriction on the movement of the connecting shaft 1. This ensures that the connecting shaft 1 does not exceed the effective stroke of the second elongated bore 10 when it moves the bearing 2 to the working position.

[0074] The bearing limiting platform 12 is located at the other end of the shaft body, forming a two-end positioning structure with the shaft flange 11 connecting the shaft 1. The radial dimension of the bearing limiting platform 12 is larger than the inner diameter of the bearing 2, ensuring the stable position of the bearing 2 on the connecting shaft 1, avoiding lateral displacement or falling off of the bearing 2 during movement, and ensuring that the bearing 2 moves smoothly to the working position or storage position under the drive of the connecting shaft 1.

[0075] The sliding assembly also includes a connector 5, which is connected to the portion of the connecting shaft 1 that protrudes from the support seat 3. In this embodiment, the connector 5 can be a nut, and the connector 5 is threadedly connected to the connecting shaft 1. The connection between the connector 5 and the connecting shaft 1 can also be completed by welding or other reliable methods, ensuring that the connector 5 can firmly fix the connecting shaft 1 during use, preventing loosening or detachment under movement or load. The addition of the connector 5 provides additional physical support for the connecting shaft 1 and the bearing 2, especially during the process of the bearing 2 moving from the storage position to the working position, or when the battery box is under heavy load in the working position. The connector 5 can significantly enhance the structural stability of the entire sliding assembly, preventing damage or failure of the assembly due to excessive load or impact during movement.

[0076] Connector 5 not only enhances the stability of the assembly but also ensures the smooth movement of bearing 2. Under the action of adjusting component 6, rack 4 drives connecting shaft 1 and bearing 2 to rise and fall. The stable connection between connector 5 and connecting shaft 1 avoids shaking or offset during movement, ensuring a smooth transition of bearing 2 at opening 9, reducing resistance during operation, and improving operational efficiency and comfort.

[0077] In this embodiment, as Figure 6 , Figure 7 As shown, there are two support components, which are symmetrically arranged at the bottom of the housing 7. When the bearing 2 is in the working position, the tops of the two support components at both ends of the housing 7 abut against each other.

[0078] Optionally, bearing 2 can be configured as a cylindrical roller bearing or a ball bearing. Cylindrical rollers are cylindrical in shape, capable of withstanding large radial loads, while also possessing a certain load-bearing capacity in terms of axial loads. As part of the sliding assembly, selecting bearing 2 as a cylindrical roller bearing or ball bearing significantly reduces the friction between the battery box and the support 3, especially when the battery box needs to be removed from or pushed into the support 3. This characteristic not only improves the efficiency of battery box loading and unloading but also reduces damage to the paint or plating on the bottom surface of the battery box and the surface of the support 3 during movement, lowering maintenance costs and extending the service life of the overall structure. Both the cylindrical roller bearing and ball bearing designs ensure smooth movement of bearing 2 at the opening 9 under the drive of the connecting shaft 1.

[0079] Optionally, the rack 4 is split into two parts, with each end of the rack 4 connected to the support 3. The rack 4 is designed as two independent short racks, each with one end connected to the bearing 2 via a first elongated hole 8, and the other end connected to a corresponding position on the support 3. This design reduces the risk of deformation of the rack 4 during installation, and the short racks are easier to install, remove, and maintain. The rack 4, split into two parts, can be adjusted independently. The movement of each short rack can be controlled individually by operating the adjusting element 6 (such as a nut). This design is particularly important in situations where space is limited or precise adjustment is required, improving operational flexibility and accuracy.

[0080] As can be seen from the above description, the embodiments of this utility model achieve the following technical effects:

[0081] (1) By using a combination of bearings and racks, the adjusting assembly can rotate in a preset direction, allowing the adjusting assembly to drive the bearing to the storage position and the working position. The contact method between the battery box and the battery rack changes from surface contact to point contact or line contact, effectively reducing friction, lowering the risk of surface damage caused by friction, and extending the service life of the battery box and battery rack.

[0082] (2) By setting up adjustment components, the efficiency of battery box installation and disassembly is improved. It can be easily completed with only manual operation, which greatly facilitates the maintenance and replacement of battery box.

[0083] The above embodiments can also be used in the field of equipment technology. That is, according to another aspect of the present invention, a power battery is provided, including a battery box, wherein the battery box is any of the battery boxes in the above embodiments.

[0084] For ease of description, spatial relative terms such as "above," "on top of," "on the upper surface of," "above," etc., are used herein to describe the spatial positional relationship of a device or feature as shown in the figures to other devices or features. It should be understood that spatial relative terms are intended to encompass different orientations in use or operation beyond the orientation of the device as described in the figures. For example, if the device in the figures were inverted, a device described as "above" or "on top of" other devices or structures would subsequently be positioned as "below" or "under" other devices or structures. Thus, the exemplary term "above" can include both "above" and "below." The device may also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatial relative descriptions used herein will be interpreted accordingly.

[0085] In addition to the above, it should be noted that the terms "one embodiment," "another embodiment," and "embodiment" used in this specification refer to specific features, structures, or characteristics described in connection with that embodiment, which are included in at least one embodiment described in the general description of this application.
