[0006] The lock body includes a lock body fixing seat, a first fixing plate, a second fixing plate, and a third fixing plate fixed on the lock body fixing seat. The first fixing plate and the second fixing plate are respectively provided with a first through hole and a second through hole. The lock body further includes a fixing tube and a bushing arranged in the fixing tube. The bushing is fixedly connected to the fixing tube. The fixing tube is arranged in the first through hole and the second through hole, and the lock tongue slides in the bushing;

[0007] The output end of the driving element is fixedly connected to a transmission rod, the transmission rod is used to drive the lock tongue to move, and an elastic element is also sleeved on the transmission rod.

[0008] Furthermore, a connecting plate is also provided on the lock body fixing seat. One side of the first fixing plate, the second fixing plate, and the third fixing plate is fixedly connected to the lock body fixing seat, and the side far from the lock body fixing seat is fixedly connected to the connecting plate. A protective cover is also sleeved outside the lock body fixing seat, and the protective cover is fixed on the lock body fixing seat.

[0009] Furthermore, a lock hole is provided on the lock tongue, a pin hole is provided on the transmission rod, and a pin passes through the lock hole and the pin hole to connect the lock tongue and the transmission rod.

[0010] Furthermore, the third fixing plate is provided with a third through hole, and the transmission rod passes through the third through hole to be connected to the lock tongue.

[0011] Further, the elastic element is a spring, one end of the spring abuts against the third fixing plate, and the other end abuts against the locking tongue.

[0012] The beneficial effects of the present utility model are as follows:

[0013] The bushing of the present utility model is made of copper alloy, which ensures that the frictional force of the locking tongue is as small as possible and can extend normally, ensuring the realization of normal functions. The locking tongue and the power cylinder are connected by an expansion pin and are sleeved with a spring. Through this active connection method, kinetic energy can be effectively transmitted while absorbing the rigid propagation of force and alleviating inertial displacement.

[0022] The following is a detailed description of the preferred embodiments of the present utility model in conjunction with the accompanying drawings, so that the advantages and features of the present utility model can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the protection scope of the present utility model. Specific Embodiment:

[0024] As Figures 1 to 5A locking structure for a new energy electric vehicle battery pack shown in the figure includes a lock body 1, a lock tongue 2 installed in the lock body 1, and a driving element 3 for driving the movement of the lock tongue 2;

[0025] The lock body 1 includes a lock body fixed seat 14, a first fixing plate 11, a second fixing plate 12, and a third fixing plate 13 fixed on the lock body fixed seat 14. The first fixing plate 11 and the second fixing plate 12 are respectively provided with a first through hole 111 and a second through hole 121. The lock body 1 further includes a fixed tube 16 and a bushing 17 arranged in the fixed tube 16. The bushing 17 is fixedly connected to the fixed tube 16. The fixed tube 16 is arranged in the first through hole 111 and the second through hole 121. The lock tongue 2 slides in the bushing 17; the bushing is made of copper alloy to facilitate the sliding of the lock tongue. Specifically, a connecting plate 141 is further provided on the lock body fixed seat 14. One side of the first fixing plate 11, the second fixing plate 12, and the third fixing plate 13 is fixedly connected to the lock body fixed seat 14, and the side away from the lock body fixed seat 14 is fixedly connected to the connecting plate 141. A protective cover 15 is further sleeved outside the lock body fixed seat 14, and the protective cover 15 is fixed on the lock body fixed seat 14. Specifically, the third fixing plate 13 is provided with a third through hole 131, and the transmission rod 31 passes through the third through hole 131 and is connected to the lock tongue 2. Specifically, a lock hole 21 is provided on the lock tongue 2, and a pin hole 311 is provided on the transmission rod 31. After a pin 33 passes through the lock hole 21 and the pin hole 311, the lock tongue 2 is connected to the transmission rod 31.

[0026] The output end of the driving element 3 is fixedly connected to a transmission rod 31. The transmission rod 31 is used to drive the movement of the lock tongue 2, and an elastic element 32 is further sleeved on the transmission rod 31. Specifically, the elastic element 32 is a spring. One end of the spring abuts against the third fixing plate 13, and the other end abuts against the lock tongue 2. The function of the spring is to keep a supporting force between the lock tongue and the transmission rod. Because the connection between the lock tongue and the transmission rod is a pin connection, and in the use state, when the vehicle is running, inertia will be generated, causing the lock tongue to shake. Therefore, the presence of the spring well buffers the shake generated by inertia, making the lock tongue firmly lock the battery pack.

[0027] The above are only the embodiments of the present invention, and do not limit the patent scope of the present invention. Any equivalent structural transformation made by using the content of the specification and drawings of the present invention, or directly or indirectly applied to other related technical fields, shall be similarly included in the patent protection scope of the present invention.
