Description

Technical Field

[0001] This utility model relates to the field of engineering vehicle technology, and more specifically, to a battery box assembly and an engineering vehicle. Background Technology

[0002] In related technologies, pure electric off-highway engineering vehicles need to increase the number of batteries to meet the requirements of long-term operation, resulting in an increase in the weight and volume of the battery pack and its placement gradually extending into the vehicle frame.

[0003] Currently, battery boxes are disassembled either by crane lifting or forklift removal. Crane lifting relies on external equipment, which makes resource coordination difficult and the operation steps cumbersome. Forklift removal, on the other hand, is less convenient because the battery box is located deep inside the chassis and in a compact space, and is not within the operating area of ​​the chassis. Utility Model Content

[0004] This utility model aims to solve one of the technical problems existing in the prior art or related technologies.

[0005] In view of the above, according to a first aspect of the present invention, a battery box assembly is provided. The battery box assembly is applied to an engineering vehicle, which includes a battery and a frame. A mounting bracket is provided on the frame. The battery box assembly includes a battery box, a guide rail, and a movable part. The battery box is used to house the battery and is detachably mounted on the mounting bracket. The guide rail is detachably mounted on the frame and extends along the length of the frame. At least a portion of the guide rail is located within the operating area of ​​the frame. The movable part is detachably mounted on the bottom of the battery box and is located on the guide rail. The movable part is movable on the guide rail. When the battery box is disconnected from the mounting bracket, the battery box can move on the guide rail via the movable part and move into the operating area.

[0006] The battery box assembly proposed in this utility model consists of a battery box, a guide rail, and a moving part. The battery box is used to house the battery of the engineering vehicle. The battery box is connected to the mounting bracket on the vehicle frame through a detachable structure to achieve the initial positioning of the battery box on the vehicle frame.

[0007] The guide rail is a rail structure extending along the length of the vehicle frame. It is detachably mounted on the surface of the vehicle frame, and at least a portion of it extends to the operating area of ​​the vehicle frame. Specifically, this operating area refers to the front grille location or the outer side of the engineering vehicle. The movable part is mounted at the bottom of the battery box, directly contacting the guide rail and enabling movement, specifically sliding or rolling.

[0008] In operation, the battery box assembly proposed in this utility model is fixed to the vehicle frame by a mounting bracket, so that the battery box cannot move relative to the vehicle frame, stably accommodating the battery, and thus the battery can supply power to the electrical components on the engineering vehicle.

[0009] When disassembly is required, prepare for disassembly by assembling the movable part onto the battery box and the guide rail onto the frame. At this point, the movable part and the guide rail are separated or only partially in contact, and the battery box is located deep within the frame. Afterward, disconnect the battery box from the mounting bracket. The battery box is now movable and no longer restricted by the mounting bracket to remain fixed to the frame.

[0010] Next, the battery box can be moved by pushing it, causing the bottom moving part to move along the guide rail, moving the battery box from the deep position to the operating area. Once the battery box is in the operating area, maintenance and battery replacement can be performed. The entire process does not require a crane or forklift, as the moving part allows operators to complete the task with minimal effort or simple power control, significantly simplifying the operation.

[0011] In summary, the battery box assembly proposed in this invention, through its design of extending the guide rail to the operating area, allows the battery box to be moved directly from the depth of the chassis to a position easily accessible for manual operation. This avoids the problem of forklifts being unable to reach the battery box due to limited space, thus reducing maintenance difficulty. The cooperation between the moving part and the guide rail replaces crane lifting, eliminating the need to coordinate external equipment resources, simplifying the operation steps, and improving maintenance efficiency. The detachable design of the moving part and the guide rail ensures compatibility with different vehicle models and usage scenarios. This invention, through the coordinated design of the guide rail and the moving part, achieves efficient and convenient disassembly of the battery box, significantly reducing the maintenance costs of engineering vehicles and improving operational reliability.

Therefore, the scope of protection of the present invention is not limited to the specific embodiments disclosed below.

[0035] The following reference Figures 1 to 4 This invention describes a battery box assembly 100 and an engineering vehicle provided by some embodiments of the present invention.

[0036] like Figure 1 and Figure 2As shown, in some embodiments of this utility model, a battery box assembly 100 is proposed. The battery box assembly 100 is applied to an engineering vehicle, which includes a battery and a frame. A mounting bracket is provided on the frame. The battery box assembly 100 includes a battery box 110, a guide rail portion 140, and a movable portion 120. The battery box 110 is used to house the battery and is detachably mounted on the mounting bracket. The guide rail portion 140 is detachably mounted on the frame and extends along the length direction of the frame. At least a portion of the guide rail portion 140 is located within the operating area of ​​the frame. The movable portion 120 is detachably mounted at the bottom of the battery box 110 and is located on the guide rail portion 140. The movable portion 120 is movable on the guide rail portion 140. When the battery box 110 is disconnected from the mounting bracket, the battery box 110 can move on the guide rail portion 140 via the movable portion 120 and move into the operating area.

[0037] In this embodiment, the battery box assembly 100 proposed by the present invention consists of a battery box 110, a guide rail 140 and a moving part 120. The battery box 110 is used to house the battery of the engineering vehicle. The battery box 110 is connected to the mounting bracket on the vehicle frame through a detachable structure to achieve the initial positioning of the battery box 110 on the vehicle frame.

[0038] The guide rail 140 is a rail structure extending along the length of the vehicle frame. It is detachably mounted on the surface of the vehicle frame, and at least a portion of it extends to the operating area of ​​the vehicle frame. Specifically, this operating area refers to the front grille location or the outer side of the engineering vehicle. The movable part 120 is mounted on the bottom of the battery box 110, directly contacts the guide rail 140, and moves accordingly, specifically by sliding or rolling.

[0039] In the working state, the battery box assembly 100 proposed by this utility model has the battery box 110 fixed to the vehicle frame by the mounting bracket, so that the battery box 110 cannot move relative to the vehicle frame, stably accommodating the battery, and thus the battery can supply power to the electrical components on the engineering vehicle.

[0040] When disassembly is required, prepare for disassembly by assembling the movable part 120 onto the battery box 110 and the guide rail part 140 onto the vehicle frame. At this time, the movable part 120 and the guide rail part 140 are either separated or only partially in contact, and the battery box 110 is located deep within the vehicle frame. Afterward, disconnect the battery box 110 from the mounting bracket. At this point, the battery box 110 is in a movable state and is no longer restricted by the mounting bracket to remain fixed to the vehicle frame.

[0041] Next, the battery box 110 can be moved. The moving part 120 moves along the extension direction of the guide rail 140, moving the battery box 110 from the deep position to the operating area. Once the battery box 110 has moved to the operating area, maintenance, battery replacement, and other operations can be performed on the battery box 110. The entire process does not require a crane or forklift and can be completed by manual pushing or simple power control, significantly simplifying the operation steps.

[0042] In summary, the battery box assembly 100 proposed in this utility model, through the design of the guide rail 140 extending to the operating area, allows the battery box 110 to be moved directly from the depth of the chassis to a position convenient for manual operation, avoiding the problem of forklifts being unable to reach the operating area due to space constraints, and reducing maintenance difficulty. The cooperation between the moving part 120 and the guide rail 140 replaces crane lifting, eliminating the need to coordinate external equipment resources, simplifying the operation steps, and improving maintenance efficiency. The detachable design of the moving part 120 and the guide rail 140 is compatible with different vehicle models and usage scenarios. Through the collaborative design of the guide rail 140 and the moving part 120, this utility model achieves efficient and convenient disassembly of the battery box 110, significantly reducing the maintenance cost of engineering vehicles and improving operational reliability.

[0043] Specifically, the battery box 110 is a rectangular box, which can be formed by welding multiple plates together or by connecting multiple plates with bolts. The top of the battery box 110 has a battery mounting port through which the battery is installed and removed. The sides of the battery box 110 are equipped with ventilation grilles.

[0044] Specifically, on the one hand, one end of the guide rail 140 is fixed to the deep part of the vehicle frame, and the other end extends to the operating area, such as the front grille, to ensure that the battery box 110 can be moved to a position that is convenient for manual operation. On the other hand, one end of the guide rail 140 is fixed to the deep part of the vehicle frame, and the other end extends to the operating area, such as the outside of the engineering vehicle, to ensure that the battery box 110 can be moved to a position that is convenient for manual operation.

[0045] Specifically, mounting holes are provided at the bottom of the guide rail section 140, which is then fixed to the surface of the frame with bolts.

[0046] Specifically, rubber buffer blocks are provided at both ends of the guide rail 140. When the moving part 120 moves to the end of the guide rail 140, the rubber buffer blocks absorb the impact energy through deformation to prevent the battery box 110 from colliding with the vehicle frame.

[0047] like Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, in some embodiments of this utility model, optionally, the moving part 120 includes a roller assembly 130, which includes a first mounting plate 132, a first fixing plate 134, and a roller 136.

[0049] The first mounting plate 132 is detachably disposed on the bottom of the battery box 110. Specifically, the bottom of the battery box 110 is provided with a movable part mounting point, and the first mounting plate 132 is detachably connected to the movable part mounting point on the bottom of the battery box 110 by bolts.

[0050] The first fixing plate 134 is fixed to the surface of the first mounting plate 132, and the first fixing plate 134 is fixedly connected to the first mounting plate 132.

The roller 136 can roll along the guide rail 140 to drive the electric box to move. The roller assembly 130 is rigidly connected to the battery box 110 through the first mounting plate 132 to ensure overall stability. The first fixing plate 134 serves as a support platform for the roller 136, and the roller 136 can roll freely on the guide rail 140.

[0051] This invention, by incorporating a roller assembly 130, significantly reduces movement resistance through rolling, making it easier to push the battery box 110. Disassembly can be completed manually by pushing the battery box 110, solving the problems of reliance on external equipment and cumbersome operation. The design of the guide rail 140 extending into the operating area allows the battery box 110 to be moved directly from the depth of the vehicle frame to a convenient operating position, adapting to compact space scenarios.

[0052] Specifically, the battery box assembly 100 also includes a second adjusting plate, which is disposed on the guide rail portion 140 and can contact the roller 136 to adjust the gap between the roller 136 and the guide rail portion 140 so that the wheel surface of the roller 136 cooperates with the guide rail portion 140.

[0053] Specifically, roller 136 is a cylindrical wheel.

[0054] Specifically, the roller 136 has an elastic wear-resistant layer on its surface to improve the contact stability with the guide rail 140 and extend the service life of the roller 136.

[0055] Specifically, the first fixing plate 134 is provided with reinforcing ribs to improve the installation stability of the first fixing plate 134 and increase its load-bearing capacity.

[0056] Specifically, the roller 136 has a chip removal groove on its wheel surface, which discharges dust or debris from the guide rail surface to both sides when it rolls. A dust collection chamber is provided at the end of the chip removal groove to temporarily store larger particles.

[0057] like Figure 3 and Figure 4 As shown, in some embodiments of the present invention, optionally, a rotating shaft 138 is provided on the first fixing plate 134, and a roller 136 is rotatably connected to the rotating shaft 138; the roller 136 can rotate relative to the first fixing plate 134 with the rotating shaft 138 as the axis.

[0058] In this embodiment, a rotating shaft 138 is provided on the first fixed plate 134, and a roller 136 is rotatably connected to the rotating shaft 138 and rotates relative to the first fixed plate 134 with the rotating shaft 138 as its axis. In this invention, the rotating shaft 138 passes through the center of the roller 136, and its two ends are fixed to the first fixed plate 134, forming the rotation center of the roller 136. The roller 136 rolls around the axis through the connection between the rotating shaft 138 and the first fixed plate 134. The design of the rotating shaft 138 makes the rotation of the roller 136 more precise, reduces wobble, and allows the roller 136 to rotate smoothly relative to the first fixed plate 134.

[0059] Specifically, a bearing is provided between the roller 136 and the shaft 138, which can further reduce friction, improve smoothness of movement, and extend the service life of the roller 136.

The slider is connected to the second fixing plate and slides on the guide rail 140.

[0063] In this invention, the slider assembly is fixed to the battery box 110 via a second mounting plate. The second mounting plate serves as a support platform for the slider, and the bottom of the slider contacts the surface of the guide rail 140, allowing it to move by sliding. The slider assembly can also be used to assist in the ejection of the battery box 110. It is suitable for low-speed, high-precision applications. The cooperation between the slider and the guide rail 140 allows it to withstand large loads, making it suitable for heavy-duty battery boxes 110.

[0067] In this embodiment, the present invention also provides an adjustment device in the battery box assembly 100. Specifically, the battery box assembly 100 further includes a first adjusting plate, which is disposed between the slider and the guide rail 140 and is used to adjust the gap between the slider and the guide rail 140.

[0068] Specifically, the first adjusting plate is a thin sheet structure, sandwiched between the bottom of the slider and the surface of the guide rail 140, and the gap is adjusted by increasing or decreasing the thickness or number of the first adjusting plate.
