[0034] Please see Figure 1 This utility model provides an electric bicycle; please refer to [link / reference]. Figures 1 to 6 The electric bicycle includes a battery access device 1 and a frame body 10. The battery access device 1 includes a battery module 100, a mounting base 200, a first locking device 300, and a second locking device 400. The mounting base 200 has a mounting groove 201, on which the battery module 100 is mounted and at least partially housed. The first locking device 300 is mounted on the mounting base 200 and is used to lock or release the battery module 100. The second locking device 400 includes an abutment 410 and a locking member 420. The abutment 410 is rotatably mounted on the battery module 100, and the locking member 420 is mounted on the mounting base 200. The second locking device 400 is used to lock or release the battery module 100 when the first locking device 300 is in the released state. When the second locking device 400 is in the locked state, the locking member 420 abuts against the abutment member 410 to lock the battery module 100. Rotating the abutment member 410 separates it from the locking member 420, thus releasing the battery module 100. At this point, the second locking device 400 is in the released state. After the first locking device 300 is unlocked, the second locking device 400 will continue to lock the battery module 100, achieving a secondary locking of the battery module 100 and preventing it from falling to the ground and being damaged due to insufficient grip after the first locking device 300 is unlocked.

[0035] Specifically, please refer to Figure 7 and refer to Figure 6The abutment 410 includes a fixed end 411 and an operating end 412. The fixed end 411 is rotatably fixed to the battery module 100 and is located near the bottom of the mounting groove 201. The operating end 412 is installed on the side of the abutment 410 away from the fixed end 411 and is located near the opening of the mounting groove 201. The second locking device 400 also includes a spring member 430, which is used to push the abutment 410 so that the locking member 420 abuts against the abutment 410. When the first locking device 300 is in the locked state, the first locking device 300 is unlocked, the locking member 420 abuts against the abutment 410, and the battery module 100 extends at least partially out of the mounting groove 201 under the action of spring force and / or gravity. At this time, the second locking device 400 is in the locked state. When the user operates the control terminal 412, the elastic element 430 is subjected to force, the fixed end 411 rotates, and the locking element 420 releases the abutment 410. At this time, the second locking device 400 is in the released state. In this embodiment, the elastic element 430 is a spring pin, and the elastic element 430 is disposed between the battery module 100 and the abutment 410. The spring pin is subjected to pressure, thereby pushing the abutment 410 against the locking element 420. However, this application does not limit the force on the elastic element 430 or the type of the elastic element 430. In other embodiments of this application, the elastic element 430 can also be a spring, a sheet, or a tension spring, etc., which are accessories with elasticity or tension. In this case, the specific installation position of the elastic element 430 is also different according to the actual force applied, so as to push the abutment 410 against the locking element 420.

[0036] It should be noted that, in this embodiment of the application, in order to facilitate user operation of the operating terminal 412, the battery module 100 is provided with a second locking device 400. After the first locking device 300 is unlocked, it will move downward under its own gravity to protrude the operating terminal 412, thereby facilitating user operation and improving user experience. However, in other embodiments of this application, the battery module 100 may also protrude the operating terminal 412 by setting a spring or other elastic part, or it may protrude the operating terminal 412 by both elasticity and gravity, so as to facilitate user operation.

[0037] Further, please refer to Figure 7 and refer to Figure 6The operating end 412 has an operating protrusion 412a on the side facing the locking member 420. When the second locking device 400 locks the battery module 100, the operating protrusion 412a facilitates the user to push the operating end 412, thereby facilitating the user's operation and improving the user experience. In this embodiment, the operating protrusion 412a is used to facilitate user operation and reduce the thickness of the abutment member 410. However, in other embodiments of this application, the operating end 412 can have other structures. For example, in some embodiments of this application, the operating end 412 can be directly provided with a hole for the user to insert their finger for operation. Specifically, the operating end 412 can be provided with an operating hole (not shown) at one end in the direction of the battery module 100 exiting the mounting groove 201. In this case, the operating hole is a blind hole. Alternatively, the operating end 412 can be provided with an operating ring (not shown), i.e., it has a through hole structure. Or, in some embodiments of this application, the operating end 412 can be provided with at least two of the above structures simultaneously.

[0038] Specifically, please refer to Figure 7 and refer to Figure 6 The abutment 410 includes an abutment body 413. In the direction in which the battery module 100 exits the mounting slot 201, a fixed end 411 and an operating end 412 are positioned near the two ends of the abutment body 413. The abutment body 413 protrudes towards the locking member 420 to form an abutment protrusion 413a. The abutment protrusion 413a includes an abutment side surface 413a1 and a guide end surface 413a2, which are set at an acute angle to each other. When the second locking device 400 is in the locked state, the abutment side surface 413a1 abuts against the locking member 420. The guide end surface 413a2 is used to avoid the locking member 420 when the battery module 100 exits the mounting slot 201, thereby facilitating the unlocking of the second locking device 400 and preventing the abutment 410 from abutting against the locking member 420 again under the action of the elastic member 430, which would affect the user experience.

[0039] For the first locking device 300 mentioned above, please refer to Figure 6The first locking device 300 includes a latch 310 and a drive structure 320. The latch 310 is mounted on the mounting base 200 and locks or releases the battery module 100 through reciprocating motion. The drive structure 320 is mounted on the mounting base 200 and connected to the latch 310, and is used to drive the latch 310 to move. Specifically, the latch 310 is slidably mounted on the mounting base 200, and the drive structure 320 is rotatably mounted on the mounting base 200. The rotation of the drive structure 320 drives the latch 310 and the battery module 100 to separate, thereby releasing the battery module 100. The drive structure 320 is provided with a keyhole (not shown), and the user can rotate the drive structure 320 by inserting a key into the keyhole. The first locking device 300 also includes a spring (not shown). When the key is removed from the keyhole, the latch 310 is reset under the action of the spring, and the first locking device 300 returns to the locked state. The locking tongue 310 is tilted towards the side of the opening of the mounting groove 201. When the user needs to lock the battery module 100, the battery module 100 is pushed into the mounting groove 201, and the tilted surface of the battery module 100 and the locking tongue 310 abut against each other, thereby pushing the locking tongue 310 backward. After reaching the limit position, the locking tongue 310 abuts against the battery module 100 under the action of the spring.

[0040] It should be noted that the first locking device 300 is a common structure in the prior art. This application does not limit the specific structure of the first locking device 300. In other embodiments of this application, the first locking device 300 can be other lock structures to achieve locking and releasing of the battery module 100.

[0041] Preferably, please refer to Figure 8 and refer to Figure 6 The first locking device 300 further includes a wear-resistant component 330, which is mounted on the battery module 100. The wear-resistant component 330 has a locking portion 331. When the first locking device 300 is in the locked state, the locking tongue 310 and the locking portion 331 abut against each other. When the first locking device 300 is in the released state, the locking tongue 310 and the locking portion 331 are separated. The wear-resistant component 330 cooperates with the locking tongue 310 to prevent wear on the battery module 100 during repeated locking cycles. Specifically, in this embodiment, the wear-resistant component 330 is a metal sheet that fits against the end of the battery module 100, and the wear-resistant component 330 is fixed to the end of the battery module 100 by screws. It should be noted that this application does not limit the specific structure, material, or installation method of the wear-resistant part 330 on the battery module 100. For example, in other embodiments of this application, the wear-resistant part 330 may be a wear-resistant plastic part, or in other embodiments of this application, the wear-resistant part 330 may also be made of wear-resistant plastic at the end of the battery module 100, that is, the wear-resistant part 330 and the end of the battery module 100 are integrally formed.

[0042] Preferably, please refer to Figure 4 The first locking device 300 further includes a pop-out member 340, which is disposed on the mounting base 200 and is used to eject the battery module 100 from the mounting slot 201. Specifically, when the first locking device 300 is in the locked state, the pop-out member 340 abuts against the battery module 100. When the user drives the drive structure 320, the locking tongue 310 releases the battery module 100, and the pop-out member 340 ejects the battery module 100 from the mounting slot 201.

[0043] Preferably, the abutment body 413 has a guide slope 413b on the side facing the locking member 420. When the user drives the drive structure 320, the locking tongue 310 releases the battery module 100, and the pop-out member 340 pops the battery module 100 out of the mounting groove 201. The guide slope 413b guides the abutment member 410 so that the battery module 100 partially slides out of the mounting groove 201 until the abutment side 413a1 abuts against the locking member 420, thereby preventing the abutment member 410 and the locking member 420 from abutting and jamming when the battery module 100 pops out.

[0044] Preferably, please refer to Figure 6 In conjunction with the above figures, the battery loading and unloading device 1 also includes a battery cover 500 and a spring-loaded cover structure 600. The battery cover 500 is detachably mounted on the mounting base 200. The spring-loaded cover structure 600 is provided with a button 610, which is mounted on the battery cover 500 and at least partially exposed on the outside of the battery cover 500. When the spring-loaded cover structure 600 is in the locked state, the battery cover 500 at least partially covers the opening of the mounting groove 201. After pressing the button 610, the battery cover 500 is ejected by the spring-loaded cover structure 600 in the direction of exiting the mounting groove 201, at which point the spring-loaded cover structure 600 is in the released state. This creates a relatively sealed environment for the battery module 100, reducing the probability of damage to the battery module 100 caused by accidental collisions. Furthermore, the design of the spring-loaded cover structure 600 allows the user to release the battery cover 500 simply by pressing the button 610, making operation simple and convenient.

[0045] Specifically, please refer to Figure 6Referring to the above figures, the spring cover structure 600 includes a sleeve 620, a ball pin 630, a ball 640, a pressing accessory 650, and an elastic element 660. The sleeve 620 is mounted on the battery cover 500 and has a cylindrical hole 621. The ball pin 630 is mounted on the mounting base 200 and inserted into the cylindrical hole 621. The ball 640 is mounted on the cylindrical wall of the sleeve 620 and can move radially along the sleeve 620. The pressing accessory 650 is mounted on the battery cover 500, and a button 610 is mounted on the pressing accessory 650. The pressing accessory 650 has a limiting part 651, which abuts against the ball 640 so that the ball 640 at least partially extends into the cylindrical hole 621 of the sleeve 620, preventing the ball pin 630 from exiting the sleeve 620. One end of the elastic element 660 is mounted on the ball head pin 630, and the other end is mounted on the mounting base 200. The elastic element 660 is used to push the ball head pin 630 out of the sleeve 620. When the spring cover structure 600 is in the locked state, the ball head pin 630 is at least partially inserted into the cylindrical hole 621, the elastic element 660 abuts against the ball head pin 630 and the pressing accessory 650, and the limiting part 651 abuts against the ball 640. The ball 640 extends at least partially into the cylindrical hole 621 of the sleeve 620, and the ball head pin 630 is fixed in the cylindrical hole 621 under the limiting action of the ball 640. When the button 610 is pressed, the limiting part 651 slides to release the limiting action on the ball 640, the ball 640 exits the cylindrical hole 621, and the ball head pin 630 pops out of the cylindrical hole 621 under the elastic force of the elastic element 660. At this time, the spring cover structure 600 is in the released state. The ball-head pin 630 is inserted into the cylindrical hole 621 until it abuts against the elastic member 660. The limiting part 651 abuts against the ball 640. The ball-head pin 630 is held and fixed in the cylindrical hole 621 by the limiting of the ball 640. The ball 640 extends at least partially into the cylindrical hole 621 of the sleeve 620. At this time, the spring cover structure 600 returns to the locked state. It should be noted that in order to reduce the thickness of the battery cover 500 and to prevent the ball-head pin 630 from being damaged by collision with the battery cover 500, in this embodiment of the application, the sleeve 620 is provided on the battery cover 500 and the ball-head pin 630 is provided on the mounting base 200. However, this application does not limit this. In other embodiments of this application, the sleeve 620 may be provided on the mounting base 200 and the ball-head pin 630 may be provided on the battery cover 500. It should also be noted that this application does not limit the specific installation position and type of the elastic element 660. In some embodiments of this application, one end of the elastic element 660 can be installed on the ball head pin 630 and the other end on the sleeve 620, so that the elastic element 430 pushes the ball head pin 630 out of the sleeve 620. The elastic element 660 can be a spring, tension spring, or spring pin, or other parts with elasticity or tension. In addition, in the embodiments of this application, the button 610 and the pressing accessory 650 are integrally formed, but this application does not limit this. In other embodiments of this application, the button 610 and the pressing accessory 650 can be two parts installed together.
