[0047] See attached Figure 3The locking mechanism 3 includes a lock buckle 30, a locking spring 31 and a control assembly 32; the box body 1 is provided with a mounting hole 14 connected to the battery compartment 12; the lock buckle 30 is slidably installed in the mounting hole 14, and the lock buckle 30 can slide along the axial direction of the mounting hole 14, the locking spring 31 is sleeved on the lock buckle 30, and one end of the locking spring 31 abuts against the bottom wall of the mounting hole 14; the lock buckle 30 includes a locking tongue portion 300 and a connecting portion 301, and the locking tongue portion 300 can be engaged with the card slot 20; the control assembly 32 is installed on the box body 1, and the control assembly 32 is drivingly connected to the connecting portion 301, the locking tongue portion 300 of the lock buckle 30 can be engaged with the card slot 20 through the locking spring 31, and the locking tongue portion 300 of the lock buckle 30 can be driven away from the card slot 20 through the control assembly 32. Specifically, the axial direction of the mounting hole 14 is perpendicular to the insertion and ejection direction of the battery 2, that is, the lock buckle 30 slides so that the lock tongue portion 300 is retracted into the mounting hole 14 to release the engagement with the card slot 20 to achieve displacement unlocking of the battery 2, and slides so that the lock tongue portion 300 slides out of the mounting hole 14 to engage with the card slot 20 to achieve locking of the battery 2. The card slot 20 and the lock tongue portion 300 of this embodiment have L-shaped cross-sections, and the straight side of the card slot 20 faces the bayonet 120 of the battery compartment 12, and the oblique side of the lock tongue portion 300 faces the bayonet 120 of the battery compartment 12, that is, when the battery 2 is pushed into the battery compartment 12 through the bayonet 120, the battery 2 The edge of the locking tongue portion 300 abuts against the hypotenuse of the locking tongue portion 300, forcing the locking tongue portion 300 to be retracted into the mounting hole 14 and compressing the locking spring 31. Since the top end surface of the battery 2 is a flat surface and there is only a concave structure in the card slot 20, when the battery 2 is inserted inward until the card slot 20 and the mounting hole 14 are aligned, the locking tongue portion 300 is not restricted by the top end surface of the battery 2 and is inserted into the card slot 20 under the elastic force of the locking spring 31, thereby completing the automatic locking effect of the insertion of the battery 2; on the contrary, the user can drive the locking tongue portion 300 to be retracted into the mounting hole 14 by operating the component 32, at which time, the battery 2 can be removed from the battery compartment 12.

[0048] In order to prevent the lock buckle 30 from rotating circumferentially in the mounting hole 14 and causing the lock buckle 30 to fail to lock, at least two guide grooves 140 are provided on the inner wall of the mounting hole 14, and the guide grooves 140 are extended along the axial direction of the mounting hole 14; at least two guide bars 302 are correspondingly provided on the lock buckle 30, and the guide bars 302 cooperate with the guide grooves 140 to limit the circumferential rotation of the lock buckle 30 in the mounting hole 14. During installation, the lock buckle 30 can be connected to the mounting hole 14 by aligning the guide bars 302 with the guide grooves 140 and inserting them. This not only facilitates installation, but also prevents the lock buckle 30 from rotating circumferentially after installation, thereby improving the structural stability of the main control box.

[0049] See attached Figure 3 -Attached Figure 6The control assembly 32 includes a pull rod 320 and a return spring 321; a connecting hole 15 is provided on the box body 1, and the connecting hole 15 and the mounting hole 14 are vertically connected to each other. The pull rod 320 is slidably installed in the connecting hole 15, and one end of the pull rod 320 is connected to the inner wall of the connecting hole 15 through the return spring 321, and the other end of the pull rod 320 is extended out of the connecting hole 15, and the other end of the pull rod 320 is provided with a hand piece 320b, and the hand piece 320b can be It abuts against the outer wall of the box body 1; an inclined end face 320a is provided in the middle of the pull rod 320, and the inclined end face 320a faces the other end of the pull rod 320; the connecting portion 301 of the lock buckle 30 is a radially extending square hole, and an inclined top wall 301a tangent to the inclined end face 320a of the pull rod 320 is provided in the square hole, and the inclined top wall 301a faces the lock tongue portion 300; pulling the pull rod 320 can drive the lock tongue portion 300 of the lock buckle 30 away from the slot 20. Specifically, the pull rod 320 is a square rod structure, which can prevent the pull rod 320 from rotating during the pulling and pulling process, and the square hole of the lock buckle 30 is opened at the center position of the lock buckle 30, that is, when the pull rod 320 is installed in the connecting hole 15, the pull rod 320 needs to pass through the square hole of the lock buckle 30, so that the inclined end surface 320a on the pull rod 320 is in contact with the inclined top wall 301a in the square hole. Under normal circumstances, the inclined end surface 320a of the pull rod 320 and the inclined top wall 301a in the square hole are at the maximum contact area, and the lock tongue portion 300 is engaged with the card slot 20. By controlling the handpiece 320b to pull the pull rod 320 in the direction away from the compartment opening 120, the inclined end surface 320a moves toward the compartment opening 120. At this time, the inclined end surface 320a forces the lock buckle 30 to move upward, that is, the lock tongue portion 300 When the locking spring 31 is pressed against the locking member 320, the locking tongue 300 is completely disengaged from the slot 20, that is, the locking member 30 releases the locking effect on the battery 2, and the user can take out the battery 2 from the battery compartment 12; the user releases the operating hand piece 320b, and the pull rod 320 is reset under the reset spring 321. At the same time, the inclined end face 320a of the pull rod 320 does not limit the inclined top wall 301a of the lock buckle 30, and the lock buckle 30 moves axially along the mounting hole 14 under the action of the locking spring 31, and the lock tongue 300 extends out of the mounting hole 14 and can be engaged with the slot 20.

[0050] In order to realize the resetting effect of the reset spring 321 on the pull rod 320, a limiting ring 150 is provided on the inner wall of the connecting hole 15, and a limiting block 320c is provided at one end of the pull rod 320. The reset spring 321 is sleeved on the pull rod 320, and one end of the reset spring 321 abuts against the limiting ring 150, and the other end of the reset spring 321 abuts against the limiting block 320c. When the pull rod 320 is pulled by the hand piece 320b, the reset spring 321 is compressed. Specifically, the limiting block 320c is detachably fixed by bolts, which facilitates the installation of the reset spring 321 on the pull rod 320, and the limiting block 320c can provide a support point for the reset spring 321 for the pull rod 320, so that when the pull rod 320 is pulled, the reset spring 321 is compressed.

[0051] See attached Figure 7 , the battery compartment 12 is also provided with an ejection assembly 4, which is used to eject the battery 2 out of the battery compartment 12 toward the compartment opening 120. When the locking mechanism 3 releases the locking effect on the battery 2 through the ejection assembly 4, the battery 2 can be automatically ejected without additional laborious operations such as pulling and pulling the battery 2, which can better improve the user experience. In this embodiment, the ejection assembly 4 is provided with two groups in this embodiment. The two groups of ejection assemblies 4 make the thrust on the battery 2 more balanced, and the ejection process is smoother. Specifically, the ejection assembly 4 includes an ejection spring 43, a top block 40, a slider 41 and a guide rail 42. The inner end of the ejection spring 43 is fixed to the guide rail At the rear end of 42, the outer end of the ejection spring 43 is connected to the ejection block 40, and the front end of the ejection block 40 abuts against the outer wall of the battery 2. The two sliders 41 are respectively arranged on both sides of the ejection block 40 and are slidably connected with the guide rail 42; when the battery 2 is pushed into the battery compartment 12, the inner wall of the battery 2 abuts against the ejection block 40 and pushes the ejection block 40 to slide backward along the guide rail 42, so that the ejection spring 43 is compressed until the battery 2 is locked by the locking tongue portion 300 of the lock buckle 30, and the ejection spring 43 remains in a compressed state. When the locking tongue portion 300 is unlocked from the card slot 20, the elastic force of the ejection spring 43 pushes the ejection block 40 to move forward, thereby pushing the battery 2 outward for a distance. In addition, limit platforms 420 are provided at the front ends of both sides of the guide rail 42, and the two sliders 41 can respectively abut against the limit platforms 420 to prevent the sliders 41 from bringing the top block 40 out of the guide rail 42. When the sliders 41 abut against the limit platforms 420, it indicates that the ejection spring 43 has pushed the top block 40 forward to the set maximum distance, and the front end of the top block 40 exceeds the front end of the guide rail 42, and the exceeding length is also the length by which the battery 2 can be pushed outward.

[0052] Embodiment 2

[0053] Only the differences from the control assembly 32 of the first embodiment are described.

[0054] See attached Figure 8 -Attached Fig.11 The control assembly 32 includes a wrench 323 and a hinge rod 324; the box body 1 forms a limit end wall 141 on the outer side of the bottom wall of the mounting hole 14; the connecting portion 301 of the lock buckle 30 passes through the bottom wall of the mounting hole 14, and the connecting portion 301 is a through hole extending radially; the wrench 323 includes adjacent unlocking surfaces 323b and upper locking surfaces 323a, and the unlocking surfaces 323b and the upper locking surfaces 323a are transitioned through rounded corners, and the unlocking surfaces 323b and the upper locking surfaces 323a can both be engaged with the limit end wall 141 Fit; the hinged rod 324 is installed on the wrench 323, and the distance between the axis of the hinged rod 324 and the unlocking surface 323b is greater than the distance between the axis of the hinged rod 324 and the upper locking surface 323a; the wrench 323 is hinged to the connecting portion 301 of the lock buckle 30 through the hinged rod 324; when the unlocking surface 323b fits with the limiting end wall 141, the lock tongue portion 300 is away from the slot 20, and when the upper locking surface 323a fits with the limiting end wall 141, the lock tongue portion 300 is engaged with the slot 20. The cam 324 is in the state of being pushed and pulled out of the locking slit 324, so that the locking slit 324 and the unlocking slit 324 can be locked. When the locking tongue 300 is engaged with the card slot 20, the user can push the lifting part 323c upward to make the end of the upper locking surface 323a away from the rounded corner detach from the limiting end wall 141, and the unlocking surface 323b is finally fitted with the limiting end wall 141 through the rounded corner. During the rotation process, since the distance between the axis of the hinge rod 324 and the unlocking surface 323b is larger, the distance between the hinge rod 324 and the limiting end wall 141 becomes larger, that is, the lock buckle 30 is driven to slide in the mounting hole 14 and drive the locking tongue 300 to detach from the card slot 20, completing the unlocking effect of the lock buckle 30 on the battery 2. On the contrary, by pushing the lifting part 323c in the opposite direction, the locking tongue 300 can be engaged with the card slot 20 of the battery 2 again. The use of rounded corner transition between the upper locking surface 323a and the unlocking surface 323b of the wrench 323 can further reduce the friction of the wrench 323 during the rotation process, making it easier for the user to operate the wrench 323.
