Technical Field

[0001] The utility model relates to the technical field of new energy battery protection boxes, in particular to a shock-resistant new energy battery protection box. Background Art

[0002] There are three main types of new energy batteries: one is the NCM ternary lithium battery, the other is the NCA ternary lithium battery, and the last one is the lithium iron phosphate battery, which is mainly used in the new energy vehicle industry and has the advantages of large storage capacity, no memory, and many charge and discharge times.

[0003] The utility model with publication number CN211879438U discloses a shock-resistant battery protection box for new energy vehicles, including a battery box body, an outer frame, a base and a T-shaped slider. End plates are fixedly connected to both sides of the battery box body, two transverse plates are fixedly connected to the upper surface of the outer frame, a plurality of first springs are fixedly connected between the transverse plates and the end plates, a plurality of air outlets and a plurality of air inlets are respectively provided on the two side surfaces of the outer frame, two connecting plates are fixedly connected to the bottom surface of the outer frame, a second spring is fixedly connected between the T-shaped slider and the connecting plate, two convex plates are fixedly connected to the upper surface of the base, and T-shaped slide grooves are provided on the opposite surfaces of the two convex plates. A third spring is fixedly connected between the two ends of the T-shaped slider and the two groove walls of the T-shaped groove. In the above application document, when the battery box is subjected to impact force from the left and right directions, the second cylinder slides left and right in the connecting plate and the second spring is squeezed, thereby achieving buffering of the battery box in the left and right directions. The T-shaped slider slides back and forth in the T-shaped groove and the third spring is squeezed in the T-shaped groove, thereby achieving buffering of the battery box in the front and back directions. Its anti-seismic effect is poor, and the rebound of the second and third springs after being squeezed will cause the battery box to shake more greatly, which is not conducive to protecting the battery box.

[0011] (1) The present application is provided with a shock-resistant mechanism, thereby reducing the damage to the protective box and the internal new energy battery caused by the impact force in the front, back, left and right directions. At the same time, the cooperation of the contact rod and the deceleration particles can reduce the shaking caused by the rebound of the telescopic spring and the compression spring after the impact.

[0012] (2) The present application is provided with an alarm mechanism, so that when the impact force in the left and right directions is too large and the protective box is likely to collide with the fixed block, the alarm will be triggered to emit a sound to warn the user to use it with caution.

DETAILED DESCRIPTION

[0018] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0019] Embodiment 1

A sliding column 4 is slidably connected inside the circular groove 3. A protective plate 5 is fixedly connected to the top of the sliding column 4. An elastic spring 6 is fixedly connected to the bottom of the protective plate 5. An anti-seismic mechanism 7 is provided on the top of the mounting seat 1. An alarm mechanism 8 is provided on the side of the protection box 2. The anti-seismic mechanism 7 comprises a fixed block 71, a contact rod 78, and a deceleration particle 79. The fixed block 71 and the deceleration particle 79 are fixedly connected to the top of the mounting seat 1. A sliding groove 72 is provided on the side of the fixed block 71. A sliding plate 74 is slidably connected to the inside of the sliding groove 72 through a telescopic spring 73. A sliding block 75 is slidably connected to the inside of the sliding groove 72. The end of the sliding block 75 away from the sliding groove 72 is fixedly connected to a sliding rod 76 and a compression spring 77. In the initial state, the sliding block 75 is fitted with the sliding plate 74, and the end of the compression spring 77 away from the sliding block 75 is in conflict with the side of the protection box 2. When the protection box 2 is impacted in the front and rear directions, the protection box 2 drives the sliding rod 76 and the sliding block 75 to squeeze the sliding plate 74, and the telescopic spring 73 absorbs the impact force and gradually tightens. When the protection box 2 is impacted in the left and right directions, the compression spring 77 absorbs the impact force and gradually tightens. The protection box 2 is slidably connected to the sliding rod 76, and the contact rod 78 is fixedly connected to the bottom of the protection box 2. The contact rod 78 and the deceleration particles 79 are both made of rubber, and the contact rod 78 and the deceleration particles 79 are close to each other. When the protection box 2 moves forward and backward or left and right, it will drive the contact rod 78 to contact the deceleration particles 79, and the rubber contact rod 78 and the deceleration particles 79 rub to generate resistance.

[0021] When in use, install the overall mechanism and install the new energy battery inside the protective box 2. When the protective plate 5 can reduce the impact force from the top, when the protective box 2 is impacted in the front and rear directions, the protective box 2 drives the sliding rod 76 to move forward and backward, and the sliding rod 76 moves forward and backward to drive the sliding block 75 to squeeze the sliding plate 74. At this time, the telescopic spring 73 absorbs the impact force and gradually tightens, and then the telescopic spring 73 rebounds to drive the protective box 2 to return to its original position. When the protective box 2 is impacted in the left and right directions, the protective box 2 slides left and right on the sliding rod 76, and the compression spring 77 absorbs the impact force and gradually tightens, and then the compression spring 77 rebounds to drive the protective box 2 to return to its original position. When the protective box 2 moves forward and backward or left and right, it will drive the contact rod 78 to contact the deceleration particle 79. The friction between the rubber contact rod 78 and the deceleration particle 79 generates resistance, which can reduce the speed and amplitude of the telescopic spring 73 and the compression spring 77 when they rebound, reduce the shaking of the protective box 2, and better protect the protective box 2 and the new energy battery inside.

The width of the end of the pressure chamber 81 close to the airbag 82 is smaller than the width of the slide groove 72, and the airbag 82 is in an expanded state in the initial state. When the protection box 2 moves left and right too much, the end of the pressure chamber 81 close to the airbag 82 enters the slide groove 72, and the airbag 82 is squeezed with the inner wall of the slide groove 72. The air pressure in the airbag 82 enters the pressure chamber 81, and the other end of the pressure chamber 81 slides inside. The alarm 84 is electrically connected to the new energy battery in the protective box 2 through a wire. A contact switch 85 is provided at the bottom of the alarm 84. When the contact switch 85 is touched, the alarm 84 will be turned on and sound. The alarm 84 is powered by the new energy battery in the protective box 2. The air pressure chamber 81 is located directly below the alarm 84, and the end of the piston rod 83 away from the air pressure chamber 81 is close to the contact switch 85. The air pressure in the airbag 82 enters the air pressure chamber 81 to drive the piston rod 83 to move upward, and the piston rod 83 moves upward and contacts with the contact switch 85.

[0024] During use, on the basis of Example 1, when the impact on the left and right directions of the protective box 2 is too great, causing the protective box 2 to move too much to the left and right, the end of the air pressure chamber 81 close to the airbag 82 will enter the slide groove 72, and the airbag 82 will be squeezed against the inner wall of the slide groove 72. The air pressure in the airbag 82 enters the air pressure chamber 81, and the air pressure in the airbag 82 enters the air pressure chamber 81 to drive the piston rod 83 to move upward. The piston rod 83 moves upward and contacts the contact switch 85. When the contact switch 85 is contacted, the alarm 84 will be turned on and a sound will be emitted.
