The intermediate tower 106 is fixed above the base 105, and the top tower 107 is fixed above the intermediate tower 106. A first center hole 108 is opened on the intermediate tower 106, and a second center hole 109 is opened on the top tower 107. Figure 1 As shown, the bottom of the impact assembly 101 is arranged in the first center hole 108 of the middle tower 106. The top of the impact assembly 101 extends upwardly out of the second center hole 109. The tower assembly 102 is used to guide the impact assembly 101 to remain in the vertical direction. When the impact assembly 101 is subjected to impact energy, it impacts upwardly along the vertical direction formed by the first center hole 108 and the second center hole 109.

[0073] refer to Figure 4 The power storage assembly 103 includes a motor 110, a positioning barrel 111, a spring 112 and a moving beam 113. Figure 1 As shown, the motor 110 is arranged on one side of the base 105. The positioning barrel 111 is vertically arranged on the base 105, and the top of the positioning barrel 111 can extend upward into the bottom of the impact assembly 101. The moving beam 113 is fixedly arranged at the bottom of the positioning barrel 111, and the spring 112 is sleeved on the positioning barrel 111. The bottom of the spring 112 contacts the top of the moving beam 113. The motor 110 is used to lift the moving beam 113 so that the spring 112 accumulates elastic potential energy. During the upward movement of the moving beam 113, the top of the spring 112 contacts the bottom surface of the impact assembly 101. The moving beam 113 gradually approaches the middle tower 106, and the spring 112 is continuously compressed to accumulate elastic potential energy.

[0074] refer to Figure 5 The release assembly 104 includes a cylinder 114 and a trigger 115. The cylinder 114 is used to control the trigger 115 to lock or release the impact assembly 101.

[0075] In some examples, reference Figure 3 The tower assembly 102 includes a first support rod 116 and a second support rod 117. The first support rod 116 is vertically arranged on the base 105, and the middle tower 106 is fixed on the top of the first support rod 116. The second support rod 117 is vertically arranged on the middle tower 106, and the top tower 107 is fixed on the top of the second support rod 117. By way of example and not limitation, the first support rod 116 and the second support rod 117 can be connected as one to form a support member that passes through the middle tower 106, so as to simultaneously support the middle tower 106 and the top tower 107, and provide a stable structure.

[0076] In some examples, reference Figure 4 , Figure 1 and Figure 2 The power storage assembly 103 further includes a pulley assembly 118 and a screw 119. The screw 119 is located in the vertical direction, penetrates the positioning barrel 111 and is threadedly matched with the positioning barrel 111. The motor 110 drives the screw 119 to rotate through the pulley assembly 118, and the screw 119 drives the positioning barrel 111 and the moving beam 113 to rise and fall in the vertical direction.

[0077] In some examples, the force storage assembly 103 further includes a guide column 120. The guide column 120 is vertically disposed between the base 105 and the intermediate tower 106. Guide holes 121 are provided at both ends of the moving beam 113, and the guide column 120 is passed through the guide holes 121. The guide column 120 is used to guide the moving beam 113 to rise smoothly in the vertical direction, so as to prevent the moving beam 113 from deflecting, resulting in the loss of impact energy of the spring 112, and affecting the test results.

[0078] In some examples, the force storage assembly 103 further includes a linear bearing 122. The linear bearing 122 is disposed in the guide hole 121, and the guide column 120 is slidably matched with the guide hole 121 through the linear bearing 122, so as to further enhance the guiding effect and reduce friction.

[0079] In some examples, reference Figure 5 The release assembly 104 further includes a fixing bracket 123 . The fixing bracket 123 is fixedly disposed on the base 105 , and the cylinder 114 is disposed on the upper portion of the fixing bracket 123 .

[0080] In some examples, the release assembly 104 further includes a connecting bracket 124, a connecting rod 125, and a connecting shaft 126. The connecting bracket 124 is disposed on the top of the fixed bracket 123, and the connecting bracket 124 is connected to the connecting shaft 126 through the connecting rod 125. The connecting shaft 126 is arranged in a horizontal direction, and the trigger 115 is disposed at both ends of the connecting shaft 126. The cylinder 114 pushes the connecting bracket 124 to move so that the connecting rod 125 drives the trigger 115 to move through the connecting shaft 126 to lock or release the impact assembly 101.

[0081] In some examples, reference Figure 1 , Figure 3 and Figure 5 , a long slot 127 is provided on the middle tower 106, and the top end of the trigger 115 extends upward from the long slot 127. The cylinder 114 pushes the connecting bracket 124 to move so that the connecting rod 125 drives the trigger 115 to move forward and backward in the length direction of the long slot 127 through the connecting shaft 126 to lock or release the impact assembly 101. Preferably, a connecting seat 131 is provided at the front end of the bottom of the trigger 115, and the connecting seat 131 is used to limit the excessive backward movement of the trigger 115 to ensure that the trigger 115 moves accurately.

[0082] In some examples, reference Figure 6 The impact assembly 101 includes an impact barrel 128 and an impact head 129 disposed at the top center of the impact barrel 128. Figure 1 As shown, the top of the impact bucket 128 extends upwardly out of the second central hole 109 of the top tower 107 .

[0083] In some examples, the impact barrel 128 is a hollow structure. The bottom of the impact barrel 128 is open, and the positioning barrel 111 extends upward into the impact barrel 128 during the ascending process. A locking tongue 130 extending radially outward is formed at the bottom of the impact barrel 128. Figure 1 , under the action of the cylinder 114, when the trigger 115 moves forward (moves along the long slot 127 toward the motor 110 side), the trigger 115 cooperates with the lock tongue 130 to lock; when the trigger 115 moves backward to release the lock tongue 130, the trigger 115 is disengaged from the lock tongue 130. In the released state, the impact assembly 101 receives the impact energy of the spring 112, and the impact assembly 101 impacts upward. The lock tongue 130 also has a limiting function, which limits the impact assembly 101 from accidentally detaching from the top tower 107 and flying out. It should be noted that during routine testing, the distance between the impact head 129 and the battery pack shell to be tested above is limited, and the impact assembly 101 usually does not detach from the top tower 107.

[0084] The operation process of the energy impact device 100 of the present invention will be described in detail below in conjunction with all the drawings.

[0085] Assemble the tower assembly 102 and install the impact assembly 101 on the middle tower 106 so that the impact head 129 extends out of the first center hole 108 of the top tower 107;

[0086] Install the power storage assembly 103 and the release assembly 104 on the base 105, start the cylinder 114, and move the trigger 115 forward to lock with the lock tongue 130;

[0087] The motor 110 is started, and the motor 110 drives the screw rod 119 to rotate to lift the moving beam 113, and the moving beam 113 lifts the spring 112 to accumulate potential energy;

[0088] The cylinder 114 is actuated, the trigger 115 moves backward and disengages from the locking tongue 130 , the elastic potential energy of the spring 112 is released, and the impact assembly 101 moves upward to impact the bottom shell of the battery pack.

[0089] It should be noted that the impact test also includes measuring the deformation of the bottom shell of the battery pack, monitoring the temperature of the bottom shell of the power battery pack, and monitoring the leakage of the battery pack.

[0090] The energy impact device provided by the present invention has the following advantages:

[0091] 1. The overall structure is compact;

[0092] 2. The storage component stores elastic potential energy, and the release component is used to convert the elastic potential energy into impact kinetic energy. The screw feed can easily control the compression amount of the spring to achieve different energy impact tests;

[0093] 3. The lock tongue has a limiting function to eliminate the potential safety hazard of the impact assembly detaching from the tower assembly.
