Description

Technical Field

[0001] The utility model is applicable to the technical field of batteries, and particularly relates to a shock-absorbing battery box. Background Art

[0002] At present, with the rapid development of new energy technologies, electric vehicles are being used more and more. As the core component of electric vehicles, power battery boxes directly determine the overall performance and quality of electric vehicles.

[0003] However, when transporting power battery boxes, the bumps and impacts from external contact during transportation can easily damage the outside of the battery box, and there is no corresponding protective mechanism on the outside of the battery box, which causes the external impact to damage the multiple battery compartments placed inside the battery box, which may cause them to explode and affect the subsequent normal power supply. Therefore, we propose a shock-absorbing battery box. Utility Model Content

[0004] The main purpose of the utility model is to provide a shock-absorbing battery box, which can effectively solve the problems in the background technology.

[0005] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0006] A shock-absorbing battery box comprises a mounting frame, a battery compartment body is detachably mounted on the top of the mounting frame, and the number of battery compartment bodies is several groups, and hollow frames are fixedly mounted on both ends of the inner surface of the mounting frame;

[0007] A rotating screw is rotatably mounted on both ends of the inner side of each hollow frame through bearings, a follower bevel gear is fixedly sleeved on the outer top surface of each rotating screw, a fixing frame is fixedly mounted inside the two ends of the side of the mounting frame, a hand push rod is rotatably mounted on the middle end of the outer side of each fixing frame through a damping bearing, and the hand push rod penetrates and is rotatably mounted inside the side of the hollow frame, a transmission bevel gear is fixedly sleeved on the upper surface of the side of each hand push rod, and the transmission bevel gear is meshed with the outer side of the follower bevel gear;

[0008] The outer surface of each rotating screw rod is movably sleeved with a movable sleeve, and the outer surface of each movable sleeve is fixedly installed with a connecting block, and the connecting block is slidably installed inside the side of the hollow frame, and a protective partition is fixedly installed between the outer sides of each two groups of connecting blocks.

[0009] By adopting the above technical scheme, through the meshing transmission action of the transmission bevel teeth and the follower bevel teeth, and the transmission action of the rotating screw on the movable sleeve, the protective baffles can be driven to move horizontally toward or relative to each other inside the installation frame. The distance between the two groups of protective baffles can be adjusted to make them fit against the outside of the battery compartment body for reinforcement. At the same time, an isolation mechanism is created between the battery compartment body and the external environment to prevent external impact force from directly acting on the surface of the battery compartment body and causing damage to it.

[0010] As an optional solution of the technical solution of the present application, the protective baffle is movably installed at the two ends of the outer side of the top of the installation frame, and the protective baffle is located at the two ends of the outer side of the battery compartment body, and a hand-push turntable is fixedly sleeved on one side of each hand push rod away from the transmission bevel gear.

[0011] By adopting the above technical solution, the convenience of adjusting the entire device is achieved through the structural action of the hand-pushing turntable.

[0012] As an optional solution to the technical solution of the present application, hollow tubes are fixedly installed on the four corner surfaces of the outer side of the installation frame, the top end of each side of the hollow tube passes through and is slidably installed on a movable rod, a protective frame is fixedly installed on the outer end surface of each movable rod away from the installation frame, a buffer spring is movably sleeved inside each hollow tube, and the top end of the side of the buffer spring is movably fitted to the outer surface of the piston plate.

[0013] By adopting the above technical solution, the protection quality of the battery compartment body is improved through the structural effect of the buffer spring.

[0014] As an optional solution of the technical solution of the present application, a piston plate is fixedly installed on the outer top surface of each movable rod, and the piston plate is slidably installed inside the hollow tube. A damping pad is fixedly bonded to the outer surface of each piston plate, and the damping pad is slidably fitted to the inner wall of the hollow tube.

[0015] By adopting the above technical solution, the reverse vibration force of the buffer spring is ensured not to affect the overall mechanism through the structural action of the piston plate and the damping pad.

[0016] Compared with the prior art, the utility model has the following beneficial effects:

[0017] The shock-absorbing battery box of the technical solution of the present application is a battery box in which the transmission bevel gear is rotated and installed inside the hollow frame by a hand push rod. Under the meshing transmission action of the transmission bevel gear and the follower bevel gear, the hand push rod is only needed to push the transmission bevel gear to rotate synchronously, which can drive the rotating screws on both sides of the hollow frame to rotate synchronously, thereby driving the transmission sleeves sleeved on the surface thereof to move and adjust horizontally toward or relative to each other inside the hollow frame, driving the protective partition to move horizontally toward or relative to each other inside the installation frame synchronously, adjusting the distance between the two groups of protective partitions to make them fit the outer side of the battery compartment body for actuation and reinforcement, and at the same time, an isolation mechanism is provided between the battery compartment body and the external environment to prevent the external impact force from directly acting on the surface of the battery compartment body and causing damage to it;

[0018] By arranging four groups of hollow tubes on the outside of the installation frame, and slidingly installing the movable rod inside the hollow tube through the piston plate and the piston cushion, after the external impact force contacts the outside of the protective frame and causes it to move, the impact force can pass through the movable rod and the piston plate to squeeze the buffer spring to cause it to deform, thereby further buffering and eliminating the external impact force, preventing the impact force from directly acting on the outside of the battery compartment and causing damage to it.

[0024] In this technical solution (through Figure 1 , Figure 2 and Figure 3 As shown), hollow frames 2 are fixedly installed on the surfaces of both ends of the inner side of the installation frame 1, and rotating screws 24 are rotatably installed on the inner ends of each hollow frame 2 through bearings, and the outer top surface of each rotating screw 24 is fixedly sleeved with a follower bevel gear 25, and fixed frames 21 are fixedly installed inside the two ends of the side of the installation frame 1, and a hand push rod 22 is rotatably installed on the middle end of the outer side of each fixing frame 21 through a damping bearing, and the hand push rod 22 is rotatably installed inside the side of the hollow frame 2, and a transmission bevel gear 23 is fixedly sleeved on the top surface of the side of each hand push rod 22, and the transmission bevel gear is meshed with the outer side of the follower bevel gear 25.

[0025] In this technical solution (through Figure 1 , Figure 2 and Figure 3 As shown), each outer surface of the rotating screw rod 24 is movably sleeved with a movable sleeve 29, and each outer surface of the movable sleeve 29 is fixedly installed with a connecting block 27, and the connecting block 27 is slidably installed inside the side of the hollow frame 2, and a protective partition 28 is fixedly installed between the outer sides of each two groups of connecting blocks 27.

[0026] In this technical solution (through Figure 1 , Figure 2 and Figure 3 As shown), hollow tubes 3 are fixedly installed on the four corner surfaces of the outer side of the installation frame 1, and the top end of the side of each hollow tube 3 passes through and is slidably installed on a movable rod 31. A protective frame 32 is fixedly installed on the outer end surface of each movable rod 31 away from the installation frame 1, and a piston plate 34 is fixedly installed on the top surface of the outer side of each movable rod 31, and the piston plate 34 is slidably installed inside the hollow tube 3.
