[0002] A battery is a cup, tank, or other container, or part of a composite container, that contains an electrolyte solution and metal electrodes to generate an electric current. It is a device that converts chemical energy into electrical energy. However, most batteries lack protective casings, which are not easy to remove and are not wear-resistant, leaving the batteries exposed, thus shortening their service life.

[0003] A search revealed a Chinese patent (authorization publication number CN 217334177 U) that includes an outer shell and a protective shell. The inner cavity of the outer shell is provided with a protective shell, and the inner cavity of the protective shell is provided with a battery body. The outer wall of the protective shell is provided with anti-impact rods and heat dissipation fins. The anti-impact rods are provided at the corners of the outer wall of the protective shell, and heat dissipation fins are evenly provided on the top, bottom and both sides of the outer wall of the protective shell. The protective shell can protect the battery, and the anti-impact rods can reduce the impact on the battery body inside the protective shell, which can effectively prevent the battery body from being damaged by impact, greatly increasing the service life of the battery body.

[0004] However, in actual application, the device lacks a structure that is easy to disassemble, resulting in the spring being unable to be replaced after long-term use, and the protective shell being discarded. When problems occur in the circuit, it is also impossible to replace it, resulting in material waste and being unfavorable for actual operation. Utility Model Content

[0005] The utility model discloses a wear-resistant and impact-resistant battery protective shell. The device in the background art lacks a structure that is easy to disassemble, resulting in that the spring cannot be replaced after long-term use, so that the protective shell is discarded. When a problem occurs in the circuit, it cannot be replaced, resulting in a waste of materials, which is not conducive to practical operation and technical problems.

[0006] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0007] A wear-resistant and impact-resistant battery protective case, comprising an upper shell, a lower shell being provided at the bottom of the upper shell, two positioning plates being fixedly connected to both ends of the bottom of the inner wall of the lower shell, a rubber pad being fixedly connected to the bottom of the inner wall of the lower shell and located between the four positioning plates, a battery body being slidably connected between the four positioning plates, buffer assemblies being fixedly connected to the four corners on both sides of the inner wall of the lower shell, clamping plates being fixedly connected between the four buffer assemblies, pressure springs being fixedly connected to the top of the inner wall of the upper shell at equal intervals, pressure plates being fixedly connected between the bottoms of the pressure springs, the pressure plates and the clamping plates being used in conjunction with the battery body, and buffer heads being fixedly connected to the four corners of the outer sides of the upper shell and the lower shell;

[0008] A fixing assembly is provided between the upper shell and the lower shell, and the fixing assembly is used to fix the upper shell and the lower shell.

[0009] By placing the battery inside the positioning plate, fixing the upper shell and the lower shell with the fixing assembly, and positioning them with the positioning plate, when the protective shell is impacted, the internal force is clamped by the buffer assembly and the pressure spring on the top of the upper shell in cooperation with the pressure plate to buffer the battery and buffer the force applied thereto. By utilizing the pressure spring on the top in cooperation with the pressure plate, the protective shell is buffered by the softness of the buffer head from the outside. At the same time, the material of the upper shell and the lower shell is PPO material, which improves the wear resistance of the upper shell and the lower shell. The device has strong buffering and wear resistance, so that external impact and wear are alleviated, and the service life of the protective shell is increased. At the same time, it is easy to disassemble. When there is a problem with the battery, it can be quickly replaced, which is beneficial to practical application and operation.

[0010] In a preferred embodiment, the fixing assembly includes a first fixing plate, a second fixing plate, an L-shaped block, a through slot, a return spring, a sliding rod and a sliding slot, the first fixing plate is fixedly connected to the two ends of the outer side of the upper shell body, the through slots are opened at the two ends of the first fixing plate, the two ends of the outer side of the lower shell body of the second fixing plate, the sliding slots are opened at the two ends of the top of the second fixing plate, the sliding rods are fixedly connected to the inner wall of the sliding slot, the L-shaped blocks are slidably connected to the outer side of the sliding rod and slidably connected to the inner wall of the sliding slot, the L-shaped blocks are used in conjunction with the through slot, and the return springs are sleeved on the outer side of the sliding rod and located between the L-shaped block and the inner wall of the sliding slot.

[0011] By setting the L-shaped blocks on both sides close to each other, the through slot on the top of the first fixed plate can pass through the L-shaped block, and the reset spring cooperates with the slide slot to reset the L-shaped block, so that one end of the block moves to the outside of the through slot, thereby fixing the first fixed plate.

[0012] In a preferred embodiment, the buffer assembly includes a T-shaped rod, a cylinder and a buffer spring. The cylinder is fixedly connected to the four corners of the inner walls on both sides of the lower shell, the T-shaped rod is slidably connected to the inside of the cylinder, one end of the T-shaped rod extends to the outside of the cylinder and is fixedly connected to the splint, and the buffer spring is fixedly connected between the bottom of the T-shaped rod and the inner wall of the cylinder.

[0013] By setting the interaction between the buffer spring and the cylinder, the buffer spring generates an elastic force outward, and the elastic force acts on the T-bar. When the T-bar cooperates with the splint to buffer the protective shell, it generates a force on the battery during impact.

[0014] In a preferred embodiment, a placement frame is fixedly connected to the bottom of the inner wall of the lower shell, a fan is rotatably connected to the inside of the placement frame, ventilation slots are provided on both sides of the upper shell and the lower shell, the ventilation slots are used in conjunction with the fan, and the inner walls of the ventilation slots are provided with filters.

[0015] By setting up a fan and ventilation slots, the air inside the protective case can circulate, thereby dissipating heat from the battery through the airflow. The filter helps to filter dust in the air and prevent dust from entering the interior of the protective case.

[0016] In a preferred solution, one end of the placement frame is fixedly connected to a motor, an output end of the motor is fixedly connected to a rotating shaft of a fan, and a display control panel is fixedly connected to the bottom of the lower shell.

[0017] By setting a motor to drive the fan to rotate, the control display panel is electrically connected to the battery to display the battery power usage, and the battery is charged using a charging device. The control display panel controls the fan to dissipate heat from the battery panel, thereby reducing the temperature of the battery panel to prevent the battery from exploding due to excessive temperature.

[0018] In a preferred solution, the upper shell and the lower shell are both made of PPO material, which has strong wear resistance and corrosion resistance, and the buffer head is made of chloroprene rubber.

[0019] The neoprene material has strong wear resistance, and its softness allows the protective shell to cushion the body of the protective shell when it collides with the ground. The PPO material improves the wear resistance of the upper and lower shells, thereby increasing the service life of the protective shell.

[0020] The wear-resistant and impact-resistant battery protective shell provided by the utility model has the following advantages:

[0021] This practical arrangement places the battery inside the positioning plate, uses the fixing assembly to fix the upper shell and the lower shell, and uses the positioning plate to position them. When the protective shell is impacted, the internal force is clamped by the buffer assembly and the pressure spring on the top of the upper shell in conjunction with the pressure plate to buffer the battery and buffer the force applied. The pressure spring on the top is used in conjunction with the pressure plate, and the outside world buffers the protective shell through the softness of the buffer head. At the same time, the material of the upper shell and the lower shell is PPO material, which improves the wear resistance of the upper shell and the lower shell. The device has strong buffering and wear resistance, so that external impact and wear are alleviated, and the service life of the protective shell is increased. At the same time, it is easy to disassemble. When there is a problem with the battery, it can be quickly replaced, which is beneficial to practical application and operation.
