[0023] The following describes the implementation of the present invention in conjunction with the accompanying drawings and relevant embodiments. The implementation of the present invention is not limited to the following embodiments, and the present invention relates to the relevant necessary components in this technical field, which should be regarded as the common knowledge in this technical field and can be known and mastered by technical personnel in this technical field.
[0024] like Figures 1 to 5 As shown, a test device for the impact resistance of a power bank battery is provided, which is used to test the quality of a vehicle front bumper, including a pushing mechanism 1, a tire 2, a vertical plate 3, a force plate 4 and a cross bar 5. The tires 2 are respectively arranged on the left and right sides of the pushing mechanism 1, the vertical plate 3 is arranged at the rear end of the pushing mechanism 1, and the force plate 4 is arranged at the front end of the pushing mechanism 1. The pushing mechanism 1 moves back and forth between the vertical plate 3 and the force plate 4 through the tire 2. Two cross bars 5 are provided under the vertical plate 3, and the cross bars 5 extend toward the force plate 4. The two cross bars 5 are respectively close to the inner side of each tire 2; the pushing mechanism 1 includes a top seat 11, a fixing plate 12 and a reset plate 13. The top seat 11 is provided at the pushing mechanism 1. The front end of the mechanism 1 and the rear end of the reset plate 13 are provided with an opening, and the opening is matched and connected to the top seat 11. A spring 132 is provided between the opening of the reset plate 13 and the front end of the top seat 11. There are two fixing plates 12, and they are respectively provided on the left and right sides of the reset plate 13; the two tires 2 are respectively provided with wheel hubs 22, and the wheel hubs 22 are penetrated into the pushing mechanism 1 by an axle rod. The opposite sides of the two tires 2 are respectively provided with baffles 21, which are tightly attached to the sides of the tires 2, and the diameter of the baffles 21 is smaller than that of the tires 2; an opening is provided on one side of the rear end of the force-bearing plate 4, and an opening is provided on the left or right side of the force-bearing plate 4, and a placement plate 41 is penetrated through the opening on the left or right side of the force-bearing plate 4.
[0025] The present invention uses a power bank assembled at the front end of a pushing mechanism 1, and simulates driving through the pushing mechanism 1. During the simulated driving, after the front end is hit, the damage degree of the power bank is tested, and the quality of the power bank is tested.
[0026] The vertical plate 3 of the present invention is arranged at the rear end of the pushing mechanism 1. At this time, the rear end of the pushing mechanism 1 is tightly attached to the vertical plate 3. The wheels 2 on both sides of the pushing mechanism 1 are used to drive the pushing mechanism 1 to push the force-bearing plate 4 at the front end, so that the pushing mechanism 1 simulates the movement of the car, and the driven power bank hits the force-bearing plate 4, thereby testing the power bank to be placed under the push and produce an impact on the force-bearing plate 4, and observe whether the quality of the power bank is prone to breakage and deformation, and the required rectification data of the power bank can be obtained according to the severity of the damage and breakage.
[0027] The left and right sides of the reset plate 13 of the pushing mechanism 1 of the present invention are inclined and outwardly extending fixed plates 12, which use a fixed structure to fix the power bank. The spring 132 between the top seat 11 and the reset plate 13 is used to prevent the reset plate 13 and the fixed plate 12 from receiving impact pressure, which affects the internal structure of the pushing mechanism 1.
[0028] After adopting the above structure, it needs to be further explained that when the reset plate 13 and the fixed plate 12 of the present invention are not impacted, the internal spring 132 is in a relaxed state. After the reset plate 13 and the fixed plate 12 are impacted, the spring 132 can play a pressure-relieving role, and the reset plate 13 and the top seat 11 are slidingly arranged, and an undercut is provided inside the reset plate 13 for buckling the front end of the top seat 11 to prevent the reset plate 13 from popping out after the spring 132 is reset by impact.
[0029] The reset plate 13 and the fixing plate 12 of the present invention can be fixed to the power bank in a variety of ways, such as snaps, screws, etc., and adopts the common power bank installation process, which will not be described again.
[0030] The tire 2 of the present invention is limited in movement by the cross bar 5. When the tire 2 is moving, the cross bar 5 provided on the inner edge of the tire 2 plays a guiding role to prevent the tire 2 from deviating from the trajectory direction of the forward and backward movement. The baffles 21 on the inner sides of the two tires 2 are used to separate the tire 2 and the cross bar 5 to avoid friction between them and affect normal driving.
[0031] After adopting the above structure, it needs to be further explained that the tire 2 and the wheel hub 22 of the present invention are made of common tires. The use of a tire structure can make the propulsion mechanism 1 more capable of traveling in a normal manner. The tire 2 of the present invention is made of rubber. In order to avoid friction between the rubber and the cross bar 5 to reduce the driving speed, and to avoid wear of the rubber tire 2, the added baffle 21 is made of metal material. The baffle 21 is disc-shaped, and the diameter of the baffle 21 is smaller than the tire 2 to avoid the tire 2 being affected by the baffle 21 when moving.
[0032] The force-bearing plate 4 of the present invention is used to provide an impact object for the power bank to impact, and can also block the impact of the pushing mechanism 1 to prevent it from rushing out of the controllable range. After the placement plate 41 inside the force-bearing plate 4 is damaged by the test impact, it can be pulled out from the opening on the left or right side of the force-bearing plate 4 for replacement.
[0033] After adopting the above structure, it needs to be further explained that the impacted object in the placement plate 41 of the present invention is made of cement, and can also be replaced with wood according to test needs. During the impact test at the test point, several cement columns can be placed in the placement plate 41 to perform point impact test of the power bank.
[0034] The pushing mechanism 1 is a shell, and the pushing mechanism 1 also includes: a motor 15, a push switch 112 arranged at the front end of the top seat 11, a collection plate 151, an auxiliary wheel 14 and a lifting rod 16. The push switch 112 is reset by the pressure of the reset plate 13 at the front end of the top seat 11. The motor 15 and the collection plate 151 are both fixed in the pushing mechanism 1 by a bracket. The opposite sides of the motor 15 are connected to the axis of the pushing mechanism 1 passing through the hub 22. A support rod extends downward from the right to the left at the bottom of the pushing mechanism 1, and is connected to the auxiliary wheel 14 through the support rod shaft. The bottom of the auxiliary wheel 14 is horizontal with the bottom of the wheel 2, and a lifting rod 16 is provided at the rear end of the pushing chassis 1.
[0035] After adopting the above structure, it needs to be further explained that the press switch 112 of the present invention is arranged in the spring 132. After the reset plate 13 is hit, the reset plate 13 is pushed backward by the impact force, and the reset plate 13 presses the press switch 112, so that the power component inside the pushing mechanism 1 is disconnected from the power supply, thereby preventing the pushing mechanism 1 from continuing to move forward after the collision, causing the power bank installed in front of the reset plate 13 to cause a secondary collision; the auxiliary wheel 14 used in the present invention is used to assist the rear tire 2 in balancing, thereby avoiding the weight generated by the installation of the power bank at one end of the reset plate 13, causing the reset plate 13 and the fixed plate 12 to tilt forward and fall.
[0036] The lifting rod 16 of the present invention is placed on the telescopic piece of the telescopic group 31 to lift the rear end of the pushing mechanism 1 upward, so that the tire 2 of the pushing mechanism 1 leaves the ground. This setting allows the pushing mechanism 1 to accelerate the tire 2 with residual heat. When the rotation speed of the tire 2 reaches the required speed, the telescopic group 31 retracts the telescopic piece inward, so that the pushing structure 1 can immediately reach the required speed and collide in the direction of the pressure plate 4 after contacting the ground, avoiding the impact effect of the power bank driven by the pushing mechanism 1 due to the small distance between the vertical plate 3 and the force plate 4.
[0037] The method of the present invention for accelerating the waste heat of the tire 2 by lifting the pushing mechanism 1 can be used in areas with a small available range, such as indoors, thereby reducing the problem of the occupied area of the site.
[0038] The present invention adopts horizontal placement, which can avoid the excessive space occupied when vertical placement is adopted, and the speed of the tire movement is adjusted and controlled to control the impact force and speed.
[0039] The motor 15 , the push switch 112 and the cable collection plate 151 are electrically connected to each other, and the cable collection plate 151 is extended to the outside of the driving mechanism 1 using a wire tube.

The wire tube of the terminal board 321 is stored in the extension tube 33, and the wire tube provided in the extension tube 33 is connected to the central line board 151 and the terminal board 321, and is electrically connected. The extension tube 33 is a spring wire tube.
[0041] After adopting the above structure, it needs to be further explained that the console 32 of the present invention is operated by computer settings. The control of computer equipment is a well-known technology and will not be described in detail here.
[0042] The telescopic group 31 of the present invention uses an air valve to provide air pressure to push the telescopic piece outward. After contraction, the air pressure in the air valve is released, and a rebound mechanism is provided in the air valve to pull the telescopic piece inward, so that the telescopic piece can be quickly reset inward.
[0043] The extension tube 33 of the present invention is a spring wire tube, which can better accommodate the wire between the pushing mechanism 1 and the vertical plate 3, and the spring wire tube has a certain stretchability, which can prevent the wire from being pulled and broken due to being too short, or from being entangled due to being too long.
[0044] The rear end of the cross bar 5 is fixed to the bottom of the vertical plate 3 , and the front end of the cross bar 5 is not connected to the load-bearing plate 4 .
[0045] After adopting the above structure, it needs to be further explained that, in addition to being fixed to the bottom of the vertical plate 3, the crossbar 5 of the present invention can also be fixed to the ground to achieve a more solid arrangement.
[0046] The front of the force-bearing plate 4 faces the pushing mechanism 1, and a force-bearing support frame 42 is provided on the back of the force-bearing plate 4. The placement plate 41 of the force-bearing plate 4 is horizontally inserted into the force-bearing plate 4 along the opening on the left or right side of the force-bearing plate 4, and a handle 411 is provided on the side of the placement plate 41 facing the opening; the impacted material is placed in the placement plate 41.
[0047] After adopting the above structure, it needs to be further explained that the force support plate 42 of the force plate 4 is set with several weight-bearing parts and fixed to the ground. This setting can avoid the impact of the pushing mechanism 1 on the force plate 4, causing the force plate 4 to shift outward and produce a visual numerical deviation, such as the degree of damage to the power bank.
[0048] In another embodiment of the present invention, in the combination of the pushing mechanism 1 , the vertical plate 3 and the force-bearing plate 4 , other impact test objects may be installed at the front end of the pushing mechanism 1 to test the quality of the object.
