The spring exerts a thrust on the tooth plate 22 to force the tooth plate 22 to abut against the top block 29, and the crankshaft 14 is rotatably arranged on the top block 29. In the groove 21, the crankshaft 14 is located at the center of the gear 13, and one side of the gear 13 is also provided with a ratchet 23 fixedly mounted on the crankshaft 14, and the inner wall of the groove 21 is also installed The pawl 24 matched with the ratchet wheel 23 drives the ratchet wheel 23 to rotate when the second support rod 12 moves downward, and when the second support rod 12 moves upward, the pawl 24 restricts the The ratchet wheel 23 rotates; the inner wall of the groove 21 is also provided with a slot 25, the slot 25 is provided with a strong spring connected to the top rod 17, the plug rod 16 and the top rod 17 are both It is slidably arranged in the slot 25, the top rod 17 is provided with a slot on one side close to the inserting rod 16, and a push plate 26 is connected in the slot through a spring, and the push plate 26 is close to the inserting rod 16. A connecting plate 27 is fixedly connected to one side of the bottom wall of the groove 25. The connecting plate 27 and the bottom of the slot 25 are both provided with guiding inclined surfaces. The top plate 19 is located on one side of the rubber airbag 6, and the top One end of the rod 17 is connected to the top plate 19 through the second connecting rod 18, and the bottom of the battery box main body 1 is provided with a relief groove 28 for giving way to the second connecting rod 18.
[0027] When the screw rod 5 is rotated, the screw rod 5 pushes the fixing plate 4 inward, thereby fixing the battery placed in the fixing box 2.
[0028] The four sides and bottom of the fixed box 2 have springs connected to the inner wall of the battery box main body 1, which can effectively absorb shock. The bottom of the cover plate 3 is also provided with a shock absorber 31, which can be removed from the fixed box 2 The upper part has a shock absorption effect on the battery.
[0029] When the car is driving on a bumpy road section, the fixed box 2 swayed up and down. During the swaying process, the second support rod 12 will be pressed down by the first support rod 11, from Figure 5 It can be seen that a slider is fixed on the second support rod 12, and the slider is slidably arranged on the side wall of the groove 21, that is, the second support rod 12 directly slides up and down along the side wall of the groove 21, When the second support rod 12 is inserted down, the insert plate 22 contacts the teeth of the gear 13 and drives the gear 13 to rotate. The gear 13 cannot be reversed under the action of the ratchet wheel 23 and the pawl 24. The insert plate 22 is hinged on One side of the second support rod 12 cannot be rotated upwards under the action of the top block 29, but it can be rotated downwards, so when the second support rod 12 moves up, the gear 13 will not hinder the second support rod 12 from moving upwards. After the second support rod 12 is moved up, the inserting plate 22 is restored to the level under the action of the spring.
[0030] When the gear 13 rotates, it drives the crankshaft 14 to rotate. The first connecting rod 15 is hinged at the position where the crankshaft 14 is bent. image 3 with Figure 4 It can be seen from the above that when the crankshaft 14 rotates, the second connecting rod 15 will drive the plunger 16 to reciprocate. When the plunger 16 is inserted in, it will interfere with the push plate 26, thereby pushing the ejector rod 17 inward. Under the action of the ratchet wheel 23 and the pawl 24, the strong spring cannot push the ejector pin 17 outward, and the plunger 16 pushes the ejector pin 17, so that the ejector pin 17 accumulates the potential energy of the spring deformation. In the process of pushing in, the connecting plate 27 When the inclined guide surface of the push plate is in contact with the inclined surface of the slot 25, the push plate 26 gradually retracts into the groove opened on the ejector rod 17, that is, the push plate 26 gradually separates from the plunger 16. When the push plate 26 separates from the plunger 16, the ejector Under the reaction force of the spring, the rod 17 quickly pushes outwards, and the top plate 19 is driven against the rubber airbag 6 through the second connecting rod 18, and the air in the rubber airbag 6 is sprayed toward the battery to improve the heat dissipation effect;
[0031] The air intake pipe 8 of the rubber airbag 6 is provided with a one-way valve, the outside air can enter the rubber airbag 6, and the air outlet pipe 7 is also provided with a one-way valve. The air in the rubber airbag 6 enters the fixed box 2 and is sent to the battery. The length of the air outlet pipe 7 and the air inlet pipe 8 has a margin to meet the shaking of the fixed box 2, and the nozzle extension position of the air inlet pipe 8 is not shown in the figure. A filter screen should be provided at the nozzle to remove dust;
[0032] There should be absorbent cotton in the air outlet pipe 7 to reduce the humidity of the air and ensure the safety of the battery;
[0033] When the spring pushes the rod 17 outward, one end of the insert rod 16 is located on the guide slope of the slot 25. When the push rod 17 is pushed outward, the push plate 26 will not be stuck at one end of the insert rod 16, but will interfere with the insert. On the side of the rod 16, the ejector rod 17 returns to the initial position after being pushed, the gear 13 continues to rotate under the shaking of the fixed box 2, the plunger 16 is pulled out under the drive of the crankshaft 14, when the plunger 16 is pulled out to the maximum Previously, the push plate 26 is located at one end of the plunger 16 under the action of the spring, and the plunger 16 can push the ejector 17 inward again.
[0034] A sliding block is also fixed on the inserting rod 16, which is slidably arranged in a sliding groove formed on the inner wall of the slot 25, that is, the inserting rod 16 can only move along the inner wall of the slot 25.
[0035] The housing of the fixed box 2 and the push plate 4 are provided with heat dissipation holes, but they are not shown in the figure.
[0036] Further, the two heat dissipation groups are centrally symmetrically arranged in the battery box main body 1, from image 3 with Figure 4 It can be seen that the centers of the two heat dissipation groups are symmetrical with the center of the battery box body 1 as the symmetrical point.
[0037] Further, a shock-absorbing block 121 is arranged in the groove 21, a spring is arranged on the lower side of the shock-absorbing block 121, the shock-absorbing block 121 is located below the second support rod 12, and the shock-absorbing block 121 Can effectively improve the shock absorption effect.
