Abstract
Description
Technical Field
[0001] The utility model relates to the field of automobile accessories, in particular to a battery shock absorption and protection device. Background Art
[0002] There are electrolytes and sensitive components inside the battery. If the battery is subjected to excessive vibration or impact, it may cause electrolyte leakage, internal component damage or battery short circuit. Shock absorption measures can reduce these risks and thus extend the battery life. If the battery is subjected to severe shock or vibration, it may cause thermal runaway, fire or explosion. Shock absorption design can reduce this risk and improve the safety of vehicles and passengers.
[0003] In the prior art, conventional vehicle-mounted batteries are fixed on the vehicle frame, and the peripheral protection and shock absorption effect of the battery is achieved by the shock absorption of the frame itself. The bumpy vibration during vehicle driving is only damped once by the suspension and then directly transmitted to the battery body by the rigidity of the frame. The fixed battery compartment cannot provide secondary protection for the battery. When the shock effect is too large, it is easy to cause battery leakage, and the battery safety protection factor is not high. Utility Model Content
[0004] The purpose of the utility model is to solve any one of the problems in the above-mentioned technologies, thereby proposing a battery shock absorbing and protecting device.
[0005] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a battery shock absorption protection device, including a battery connected to the internal power supply circuit of the vehicle and a battery compartment for shock absorption protection arranged on the outside thereof, a fixed base is arranged at the bottom of the battery compartment, the fixed base is fixedly arranged on the frame, the bottom shaft rod of the battery compartment is passed through an eccentric bearing, the eccentric bearing is rotatably arranged on the fixed base, the damping push plate of the battery compartment is rotatably arranged in a chamber filled with hydraulic oil inside the fixed base, and a plurality of liquid level bars distributed at an angle of 45° are arranged on the side of the damping push plate.
[0006] Furthermore, the main body of the battery compartment is a protective compartment body, which is a box body with an open top and four exposed top corners and an inner edge of a guide bevel. A bottom shaft rod is arranged at the bottom center of the protective compartment body, and a damping push plate whose main body is a square plate is arranged in the middle section of the side wall of the bottom shaft rod. The outer walls of the four sides of the damping push plate are provided with a plurality of liquid level bars distributed at an angle of 45°. The liquid level bars on two adjacent sides of the four outer walls are inclined at 45° in a clockwise direction, and the liquid level bars on the other two adjacent sides of the four outer walls are inclined at 45° in a counterclockwise direction. The bottom shaft rod is rotatably inserted into an eccentric bearing.
[0007] Furthermore, the fixed base is a square table with rubber foot pads at the four corners of the bottom, a chamber filled with hydraulic oil is arranged inside the fixed base, a central axis hole penetrating into the internal chamber is arranged at the center of the upper and lower surfaces of the fixed base, the eccentric bearing seal is rotatably embedded in the central axis hole, and the damping push plate is rotatably arranged in the chamber filled with hydraulic oil inside the fixed base.
[0008] The beneficial effect of the utility model is that when the vehicle is driving, the frame transmits vibration to the fixed base, and the rubber foot pads at the four corners of the bottom of the fixed base can absorb the vertical vibration through the deformation of their materials. When the horizontal vibration is transmitted to the battery compartment, the battery compartment makes eccentric circular motion on the fixed base through the eccentric bearing under the thrust of the horizontal vibration. At this time, the damping push plate rotates eccentrically in the chamber filled with hydraulic oil inside the fixed base, and the hydraulic oil in the fixed base is offset against the liquid level gear bar of the damping push plate. The hydraulic oil has the effect of reducing the rotation speed of the rotating battery compartment and providing a rotational damping force, and the kinetic energy of the horizontal vibration is absorbed as the internal energy of the hydraulic oil to reduce shock. The battery compartment and the fixed base effectively provide secondary protection for the battery, avoiding the situation where the battery leaks when the battery shock effect is too large.

DETAILED DESCRIPTION
[0014] Please refer to Figures 1 to 4 ;
[0015] The present embodiment provides a battery shock absorption protection device, including a battery 1 connected to the internal power supply circuit of the vehicle and a battery compartment 2 for shock absorption protection arranged on the outside thereof, a fixed base 3 is arranged at the bottom of the battery compartment 2, and the fixed base 3 is fixedly arranged on the frame, the bottom shaft rod 22 of the battery compartment 2 is passed through an eccentric bearing 4, and the eccentric bearing 4 is rotatably arranged on the fixed base 3, and the damping push plate 23 of the battery compartment 2 is rotatably arranged in a chamber filled with hydraulic oil inside the fixed base 3, and a plurality of liquid level bars distributed at an angle of 45° are arranged on the side of the damping push plate 23.
[0016] Preferably, the main body of the battery compartment 2 is a protective compartment body 21, which is a box body with an open top and four exposed top corners and a guide bevel on the inner edge of the top. A bottom shaft rod 22 is arranged at the bottom center of the protective compartment body 21, and a damping push plate 23 with a main body of a square plate is arranged in the middle section of the side wall of the bottom shaft rod 22. The outer walls of the four sides of the damping push plate 23 are provided with a plurality of liquid level bars distributed at an angle of 45°, and the liquid level bars on two adjacent sides of the four outer walls are inclined at 45° in a clockwise direction, and the liquid level bars on the other two adjacent sides of the four outer walls are inclined at 45° in a counterclockwise direction, and the bottom shaft rod 22 is rotatably arranged in the eccentric bearing 4.
[0017] In a specific embodiment, the liquid level bars arranged on the four outer walls of the damping push plate 23 of the battery compartment 2 effectively increase the contact area between the damping push plate 23 and the hydraulic oil inside the fixed base 3, and greatly increase the impact area between the damping push plate 23 and the hydraulic oil when the damping push plate 23 rotates. The liquid level bars on two adjacent sides of the four outer walls are inclined at 45° in the clockwise direction, and the liquid level bars on the other two adjacent sides of the four outer walls are inclined at 45° in the counterclockwise direction, so that when the damping push plate 23 rotates in both clockwise and counterclockwise directions, a positive impact contact surface is formed between the liquid level bars and the hydraulic oil, thereby increasing the reverse resistance of the hydraulic oil to the damping push plate 23.
[0018] Preferably, the fixed base 3 is a square table with rubber foot pads 5 at the four corners of the bottom, a chamber filled with hydraulic oil is provided inside the fixed base 3, a central axis hole penetrating into the internal chamber is provided at the center of the upper and lower surfaces of the fixed base 3, the eccentric bearing 4 is sealed and rotatably embedded in the central axis hole, and the damping push plate 23 is rotatably arranged in the chamber filled with hydraulic oil inside the fixed base 3.
[0019] When the utility model is in use, when the vehicle is driving, the frame transmits vibration to the fixed base 3, and the rubber foot pads 5 at the four corners of the bottom of the fixed base 3 can absorb the vertical vibration through the deformation of their materials. When the horizontal vibration is transmitted to the battery compartment 2, the battery compartment 2 makes eccentric circular motion on the fixed base 3 through the eccentric bearing 4 under the thrust of the horizontal vibration. At this time, the damping push plate 23 rotates eccentrically in the chamber filled with hydraulic oil inside the fixed base 3, and the hydraulic oil in the fixed base 3 is offset against the liquid level gear bar of the damping push plate 23. The hydraulic oil has the effect of reducing the rotation speed of the rotating battery compartment 2 and providing a rotation damping force, thereby absorbing the kinetic energy of the horizontal vibration as the internal energy of the hydraulic oil for shock absorption.

Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
