Description

Technical Field

[0001] This invention relates to the field of electric vehicle technology, and more particularly to a battery locking device and an electric bicycle. Background Technology

[0002] An electric bicycle is a mechatronic personal transportation vehicle that uses a storage battery as auxiliary power. Based on a regular bicycle, it incorporates a motor, controller, battery, and other control components, as well as a display system. To improve space utilization, most batteries are directly installed inside the bicycle's frame tube. For ease of charging and maintenance, the battery is usually removable within the frame tube, requiring a battery lock to prevent theft. However, current battery locks primarily function as anti-theft devices and do not provide secure battery positioning. During operation, the battery is prone to movement, which can lead to poor contact and even damage.

[0003] Therefore, there is an urgent need for a battery locking device and an electric bicycle to solve the above problems. Summary of the Invention

When the locking slide plate is in the second position, it releases the locking component to reset the locking component to the locked state.

[0015] During the process of the battery being inserted into the vehicle tube, the battery can press against the trigger spring, so that the trigger spring pushes the locking slide plate from the first position to the second position.

The locking component includes a positioning pin, which is connected to the connecting plate. A first limiting hole is provided on the top of the battery. When the locking component is in the locked state, the positioning pin is inserted and positioned in the first limiting hole.

[0026] As a preferred embodiment, the locking element further includes:

[0027] A drive latch is provided, which is connected to the connecting plate.

The locking component is movably connected to the mounting top and has a locked state for locking the battery and an unlocked state for unlocking the battery. The trigger component can lock the locking component in the unlocked state. During the process of the battery entering the vehicle tube, the battery can drive the trigger component to unlock the locking component, causing the locking component to move to the locked state. This achieves the locking component's locking of the battery inside the vehicle tube, preventing the battery from shaking inside the vehicle tube and avoiding battery damage and poor contact due to battery shaking, thus achieving battery positioning protection. In addition, the unlocking mechanism is rotatably connected to the vehicle tube. By inserting the key into the unlocking mechanism and driving it to rotate, the unlocking mechanism can drive the locking component to move to the unlocked state, thereby facilitating the removal of the battery from the vehicle tube and realizing the removal of the battery.

[0065] To make the technical problems solved by the present invention, the technical solutions adopted, and the technical effects achieved clearer, the technical solutions of the present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0069] Example 1

[0070] In existing technologies, to improve the space utilization of electric bicycles, most batteries are directly installed inside the bicycle's frame tube. For ease of charging and maintenance, the battery is usually removable within the frame tube, requiring a battery lock to prevent theft. However, current battery locks primarily function as anti-theft devices and cannot lock or locate the battery. When the electric bicycle is in motion, the battery is prone to movement, which can lead to poor contact or even damage.

[0071] To solve the above problems, such as Figures 1-6 As shown, this embodiment provides a battery locking device, which includes a vehicle tube 1, a mounting mechanism, a battery 3, a locking mechanism 4, and an unlocking mechanism 5. The mounting mechanism includes a mounting base 21 and a mounting top 22, both of which are fixedly installed inside the vehicle tube 1. The battery 3 can rotate with the mounting base 21 as a rotating support to allow the battery 3 to rotate into the vehicle tube 1. The locking mechanism 4 includes a trigger component 41 and a locking component 42, which is movably connected to the mounting top 22. The locking component 42 has a locked state for locking the battery 3 and an unlocked state for unlocking the battery 3. The trigger component 41 can lock the locking component 42 in the unlocked state. During the process of the battery 3 rotating into the vehicle tube 1, the battery 3 can drive the trigger component 41 to unlock the locking component 42, so that the locking component 42 moves to the locked state. The unlocking mechanism 5 is rotatably connected to the vehicle tube 1. By inserting a key 6 into the unlocking mechanism 5 and driving the unlocking mechanism 5 to rotate, the unlocking mechanism 5 can drive the locking component 42 to move to the unlocked state.

[0072] The battery locking device provided in this embodiment allows the battery 3 to drive the trigger component 41 to unlock the locking component 42 during the process of the battery 3 being inserted into the vehicle tube 1. This causes the locking component 42 to move into the locked state, thereby locking the battery 3 within the vehicle tube 1 and preventing the battery 3 from shaking. This avoids damage to the battery 3 and poor contact caused by the shaking, thus achieving positioning protection for the battery 3. Furthermore, by inserting the key 6 into the unlocking mechanism 5 and rotating the unlocking mechanism 5, the unlocking mechanism 5 can drive the locking component 42 to the unlocked state, facilitating the removal of the battery 3 from the vehicle tube 1 and preventing the theft of the battery 3. Therefore, this battery locking device can simultaneously achieve the functions of locking and positioning the battery 3 and preventing theft.

[0073] In this embodiment, as Figure 1 and Figure 2 As shown, the vehicle tube 1 has an internal accommodating cavity 11, and a mounting port 12 communicating with the accommodating cavity 11 is provided on the side wall of the vehicle tube 1. The mounting base 21 and the mounting top 22 are both fixedly installed in the accommodating cavity 11 by bolts. When it is necessary to insert the battery 3 into the accommodating cavity 11 in the vehicle tube 1, first insert the bottom of the battery 3 through the mounting port 12 into the mounting base 21, and then use a part on the mounting base 21 as a rotating support along the... Figure 2 Rotate in the R direction to allow the battery 3 to be inserted into the receiving cavity 11, making the installation of the battery 3 more convenient.

[0074] In this embodiment, as Figures 1-4 As shown, the battery 3 includes a battery body 31, a battery base 32, and a battery top mount 33. The battery base 32 is fixedly installed at the bottom of the battery body 31, and the battery top mount 33 is fixedly installed at the top of the battery body 31. The mounting base 21 is provided with a battery plug 211, a positioning protrusion 212, and a rotating protrusion shaft 213. The battery base 32 is provided with a plug hole 321, a positioning groove 322, and a rotating support groove 323. The rotating support groove 323 can be inserted into the rotating protrusion shaft 213, and the battery 3 can rotate around the axis of the rotating protrusion shaft 213. When the battery 3 is rotated into position in the receiving cavity 11, the positioning groove 322 is completely inserted into the positioning protrusion 212, and the plug hole 321 is completely inserted into the battery plug 211, thus ensuring that the battery 3 is installed in place. By providing the rotating protrusion shaft 213 and the corresponding rotating support groove 323, it is easier to achieve the rotating installation of the battery 3 in the receiving cavity 11. In addition, by setting corresponding positioning protrusions 212 and positioning grooves 322, the accuracy and reliability of the battery base 32 being inserted and positioned on the mounting base 21 are ensured.

[0075] Preferably, in this embodiment, the battery base 32 is provided with two positioning protrusions 212 at intervals, and the battery base 32 is provided with two positioning grooves 322 at intervals. The two positioning protrusions 212 and the two positioning grooves 322 are inserted into each other in a one-to-one correspondence, which further ensures the accuracy and reliability of the battery base 32 being inserted and positioned on the mounting base 21.

[0076] Combination Figure 5 and Figure 6 The specific structure of trigger component 41 is described below, such as Figure 5 and Figure 6 As shown, the trigger assembly 41 includes a trigger spring 411 and a locking slide plate 412. The trigger spring 411 is connected to the mounting top seat 22, and the locking slide plate 412 can slide between the vehicle tube 1 and the mounting top seat 22. The locking slide plate 412 has a first position and a second position. When the locking slide plate 412 is in the first position, it engages with the locking assembly 42 to lock the locking assembly 42 in the unlocked state. When the locking slide plate 412 is in the second position, it releases the locking assembly 42 to reset the locking assembly 42 to the locked state. During the process of the battery 3 being inserted into the receiving cavity 11 through the mounting port 12, the battery 3 can press against the trigger spring 411, causing the trigger spring 411 to push the locking slide plate 412 from the first position to the second position, thereby causing the locking slide plate 412 to release the locking assembly 42 so that the locking assembly 42 can lock the battery 3.

[0077] In this embodiment, as Figure 5 As shown, the trigger spring 411 has an abutment protrusion 4111 on the side facing the locking slide plate 412. When the battery 3 presses against the trigger spring 411, the trigger spring 411 pushes the locking slide plate 412 from the first position to the second position via the abutment protrusion 4111. By providing the abutment protrusion 4111 on the trigger spring 411, the pushing operation of the trigger spring 411 on the locking slide plate 412 becomes more reliable. Furthermore, it should be noted that because the trigger spring 411 has a certain degree of elasticity, when the locking assembly 42 is in the unlocked state, the trigger spring 411 can exert a pushing force on the battery 3 towards the mounting port 12 under the action of its own elastic restoring force, making it easier to remove the battery 3 from the receiving cavity 11 through the mounting port 12.

[0078] Furthermore, in this embodiment, such as Figure 5As shown, the locking slide plate 412 is provided with a locking protrusion 4121. When the locking slide plate 412 is in the first position, it engages with the locking component 42 through the locking protrusion 4121, thereby locking the locking component 42 in the unlocked state. When the locking slide plate 412 is in the second position, the locking protrusion 4121 separates from the locking component 42, thereby releasing the locking component 42. By providing the locking protrusion 4121, the reliability of the locking of the locking slide plate 412 with the locking component 42 is ensured, and the structure is simple.

[0079] Preferably, in this embodiment, a sliding guide post 13 is provided on the cavity wall of the accommodating cavity 11. The sliding guide post 13 extends along the sliding direction of the locking sliding plate 412 and is movably inserted in the locking sliding plate 412, so that the locking sliding plate 412 can slide along the sliding guide post 13 between a first position and a second position, thereby providing guidance for the sliding movement of the locking sliding plate 412.

[0080] In addition, such as Figure 5 and Figure 6 As shown, the trigger assembly 41 provided in this embodiment also includes a first elastic reset member 413. The first elastic reset member 413 is connected between the inner wall of the vehicle tube 1 and the locking slide plate 412. The first elastic reset member 413 is configured to always drive the locked slide plate 412 and make the locked slide plate 412 always tend to move towards the first position. Specifically, in this embodiment, the first elastic reset member 413 can be a spring, which has the advantages of good elasticity and easy installation. During the process of the battery 3 being rotated into the receiving cavity 11 through the mounting port 12, the locking slide plate 412 slides to the second position under the pushing action of the trigger spring 411. At this time, the first elastic reset member 413 is in a compressed state. When the locking assembly 42 is in the unlocked state, the locking slide plate 412 can be reset to the first position under the action of the first elastic reset member 413, so that the locking slide plate 412 locks the locking assembly 42 in the unlocked state, thereby facilitating the removal of the battery 3 from the receiving cavity 11.

[0081] In this embodiment, as Figure 5As shown, the locking mechanism 4 also includes a second elastic reset member 43, which is connected between the mounting top 22 and the locking assembly 42. The second elastic reset member 43 is configured to always drive the locking assembly 42 and make the locking assembly 42 always tend to move towards the locked state. Specifically, in this embodiment, the second elastic reset member 43 can be a spring, which has the advantages of good elasticity and easy installation. It should be noted that when the locking assembly 42 is in the unlocked state, the second elastic reset member 43 is in the compressed state. When the unlocking mechanism 5 removes the unlocking of the locking assembly 42, and when the locking slide plate 412 is in the second position, the locking assembly 42 can be reset to the locked state under the action of the second elastic reset member 43.

[0082] In this embodiment, as Figure 5 As shown, the locking assembly 42 includes a connecting plate 421 and a locking member 422. The connecting plate 421 is slidably connected to the mounting top seat 22, and the second elastic reset member 43 is connected between the mounting top seat 22 and the connecting plate 421. The locking member 422 is connected to the connecting plate 421. When the locking assembly 42 is in the locked state, the locking member 422 is locked to the battery 3.

[0083] Furthermore, it should be noted that in this embodiment, the connecting plate 421 and the mounting top 22 are slidably connected along the axial direction of the battery 3. When the locking component 42 is in the unlocked state and the locking sliding plate 412 is in the first position, the locking protrusion 4121 is engaged with the side of the connecting plate 421 facing the battery 3, thereby restricting the locking component 42 from sliding and resetting to the locked state in the direction of the battery 3 under the action of the second elastic reset member 43, so as to ensure that the locking component 42 is locked in the unlocked state.

[0084] In this embodiment, as Figure 6 and Figure 7 As shown, the locking component 422 includes multiple positioning blocks 4221, all of which are connected to the connecting plate 421. The positioning blocks 4221 are arranged at intervals along the circumference of the battery 3. When the locking component 42 is in the locked state, each positioning block 4221 is inserted into the gap between the inner wall of the vehicle tube 1 and the outer wall of the battery 3, thereby achieving the positioning effect of the battery 3 at various positions in the radial direction and preventing the battery 3 from shaking in the radial direction. Optionally, in this embodiment, the size of the positioning block 4221 is adapted to the size of the gap along the radial direction of the battery 3 to ensure the positioning effect of the battery 3 in the radial direction.

[0085] In addition, such as Figure 8 and Figure 9As shown, the locking component 422 provided in this embodiment also includes a driving bolt 4223, a plug-in positioning component 4224, and a third elastic reset component 4225. The driving bolt 4223 is connected to the connecting plate 421, the plug-in positioning component 4224 is slidably connected to the mounting top seat 22 along the radial direction of the battery 3, the battery top seat 33 has a second limiting hole 332 on its side facing the plug-in positioning component 4224, the second elastic reset component 43 is connected between the mounting top seat 22 and the plug-in positioning component 4224, and the third elastic reset component 4225 is configured to always drive the plug-in positioning component 4224 and make the plug-in positioning component 4224 always tend to move away from the second limiting hole 332. When the locking component 42 is in the locked state, the driving bolt 4223 can drive the plug-in positioning component 4224 to insert into the second limiting hole 332. The structural design of the locking member 422 allows the insertion positioning member 4224 to be inserted into the second limiting hole 332 when the locking assembly 42 is in the locked state, thereby achieving the axial positioning effect of the battery 3 and preventing the battery 3 from shaking in the axial direction. Specifically, in this embodiment, the second elastic reset member 43 can be a spring, which has the advantages of good elasticity and easy installation. It should be noted that when the locking assembly 42 is in the unlocked state, each positioning block 4221 disengages from the gap in the direction away from the battery 3, and the driving bolt 4223 removes the driving force on the insertion positioning member 4224. At this time, the insertion positioning member 4224 disengages from the second limiting hole 332 under the action of the third elastic reset member 4225. Optionally, in this embodiment, as Figure 9 As shown, the insertion positioning member 4224 is provided with a insertion post 42241, which is used to insert and cooperate with the second limiting hole 332.

[0086] In this embodiment, as Figures 5-9 As shown, the mounting top 22 includes a top 221 and a mounting top plate frame 222 connected to each other. The mounting top plate frame 222 is located on the side of the top 221 away from the battery 3, and a guide hole 2221 is provided on the mounting top plate frame 222. The connecting plate 421 includes a connecting plate body 4211 and a guide post 4212 connected to each other. The guide post 4212 extends along the sliding direction of the connecting plate 421 and slides through the guide hole 2221. The second elastic reset member 43 is sleeved on the guide post 4212, and both ends of the second elastic reset member 43 are connected to the connecting plate body 4211 and the mounting top plate frame 222, respectively. By setting the guide post 4212, not only is the installation of the second elastic reset member 43 positioned, but the sliding of the connecting plate 421 is also guided.

[0087] It should be noted that in this embodiment, the driving locking tongue 4223 and the multiple positioning blocks 4221 are all connected to the connecting plate body 4211. Furthermore, when the locking assembly 42 is in the unlocked state and the locking sliding plate 412 is in the first position, the locking protrusion 4121 engages with the side of the connecting plate body 4211 facing the battery 3, thereby locking the locking assembly 42 in the unlocked state and providing support for the connecting plate body 4211 in the locked state. Additionally, it should be noted that in this embodiment, the third elastic reset member 4225 is connected between the top seat body 221 and the insertion positioning member 4224, and the top seat body 221 is fixedly installed in the receiving cavity 11 by bolts.

[0088] In this embodiment, as Figure 5 , Figure 8 and Figure 10 As shown, the battery 3 also includes a battery spring 34, which is fixedly mounted on the battery top seat 33 by bolts. The battery spring 34 has a first protrusion 341 protruding from it. The locking mechanism 4 also includes a locking tongue 44 and a fourth elastic reset member 45. The locking tongue 44 is slidably connected to the mounting top seat 22 and can engage with the first protrusion 341 to restrict the battery 3 from rotating and dislodging away from the vehicle tube 1 with the mounting base 21 as the rotating support. The fourth elastic reset member 45 is connected between the mounting top seat 22 and the locking tongue 44. The fourth elastic reset member 45 is configured to always drive the locking tongue 44 and make the locking tongue 44 always tend to move toward the first protrusion 341. It should be noted that during the process of inserting the battery 3 into the vehicle tube 1, the first protrusion 341 of the battery spring 34 on the top of the battery 3 will touch the locking tongue 44 and drive the locking tongue 44 to move away from the battery 3. At this time, the locking tongue 44 will compress the fourth elastic reset member 45. After the battery 3 is installed in place, the locking tongue 44 presses over the high point of the battery spring 34 (i.e., the first protrusion 341). At this time, the locking tongue 44 moves towards the battery 3 under the action of the fourth elastic reset member 45, so that the locking tongue 44 and the first protrusion 341 are locked together and fixed on the side facing the mounting port 12. The above arrangement enables the locking tongue 44 and the locking component 42 to achieve double locking of the battery 3, further ensuring the stability of the battery 3 installed in the receiving cavity 11. In addition, it should be noted that in this embodiment, the fourth elastic reset member 45 can be a spring, which has the advantages of good elasticity and easy installation.

[0089] It should be noted that in other embodiments, the battery 3 can be locked simply by the locking component 42, without the need for an additional locking tongue 44.

[0090] Optionally, in this embodiment, as Figure 5As shown, the battery spring 34 is also provided with a second protrusion 342, and the top seat body 221 is provided with a limit hook 2211. When the unlocking mechanism 5 drives the locking component 42 to move to the unlocked state, the locking sliding plate 412 can be reset to the first position in the direction closer to the battery 3 under the action of the first elastic reset member 413. At this time, the trigger spring 411 can realize automatic reset and push the battery 3 in the direction of the mounting port 12. At this time, the limit hook 2211 can engage with the second protrusion 342 to limit the battery 3 from rotating out of the extreme position around the axis of the rotating protrusion shaft 213 in the direction away from the vehicle tube 1, thereby avoiding the battery 3 from suddenly falling in the unlocked state and causing the battery 3 to be damaged, thus improving the protection of the battery 3.

[0091] In this embodiment, as Figure 5 and Figure 8 As shown, the battery spring 34 is provided with a hand-held pressing part 343, and the battery top seat 33 is provided with a clearance hole 333. The hand-held pressing part 343 extends into the clearance hole 333. By manually pressing the hand-held pressing part 343 through the clearance hole 333, the battery spring 34 can undergo slight elastic deformation, thereby separating the second protrusion 342 from the limiting hook 2211, so that the battery 3 can be completely removed from the receiving cavity 11. By providing the hand-held pressing part 343, it is easy to operate the battery spring 34, so that the second protrusion 342 separates from the limiting hook 2211. In addition, by extending the hand-held pressing part 343 into the clearance hole 333, the protection of the hand-held pressing part 343 is improved, and accidental operation of the hand-held pressing part 343 is avoided.

[0092] Combination Figure 6 and Figure 10 The specific structure of the unlocking mechanism 5 is explained, such as... Figure 6 and Figure 10 As shown, the unlocking mechanism 5 provided in this embodiment includes an unlocking lock cylinder 51, an unlocking connecting horizontal bar 52, and an unlocking connecting vertical bar 53. The unlocking lock cylinder 51 is rotatably connected to the vehicle tube 1, and the key 6 can be inserted into the unlocking lock cylinder 51 and drive the unlocking lock cylinder 51 to rotate. The unlocking connecting horizontal bar 52 and the unlocking connecting vertical bar 53 are connected to form an L-shaped structure, and the unlocking connecting horizontal bar 52 is connected to the unlocking lock cylinder 51. When the key 6 drives the unlocking lock cylinder 51 to unlock and rotate, the unlocking connecting horizontal bar 52 can trigger the drive latch 44 to move away from the first protrusion 341, and the unlocking connecting vertical bar 53 can trigger the drive locking member 422 to unlock the battery 3. Thus, the unlocking mechanism 5 can unlock the locking component 42 and unlock the latch 44, completing the two-way unlocking of the battery 3.

[0093] Specifically, in this embodiment, when the key 6 drives the unlocking lock cylinder 51 to rotate for unlocking, the unlocking connecting rod 53 abuts against the side of the connecting plate body 4211 facing the battery 3. As the unlocking connecting rod 53 rotates, the unlocking connecting rod 53 gradually drives the connecting plate body 4211 to move away from the battery 3, thereby enabling the locking member 422 to unlock the battery 3.

[0094] Furthermore, it should be noted that in this embodiment, as... Figure 6 , Figure 9 and Figure 10 As shown, the unlocking mechanism 5 also includes an unlocking paddle 54, which includes an L-shaped connecting part 541 and a paddle part 542 connected together. The connecting part 541 is rotatably connected to the top seat body 221, and the paddle part 542 has a through hole 5421. The latching tongue 44 includes a latching tongue body 441 and a pressing post 442 connected together. The latching tongue body 441 includes a latching tongue part 4411 and a through part 4412 connected together. The latching tongue part 4411 can engage with the first protrusion 341. The through part 4412 slides through the top seat body 221 and passes through the through hole 5421. The end of the through part 4412 that protrudes from the through hole 5421 is connected to the top seat body 221. The pressing column 442 is connected to the abutting column 442 and presses against the end face of the actuating part 542. The unlocking connecting bar 52 is eccentrically connected to the unlocking lock cylinder 51. When the key 6 drives the unlocking lock cylinder 51 to unlock and rotate, the unlocking connecting bar 52 rotates eccentrically, so that the unlocking connecting bar 52 can abut against the actuating part 542 and drive the unlocking lever 54 to rotate around the rotation connection point between the connecting part 541 and the top seat body 221. During the rotation, the unlocking lever 54 pushes the pressing column 442 and drives the entire locking tongue 44 to move away from the first protrusion 341, thereby unlocking the locking tongue 44.

[0095] To facilitate understanding of the battery locking device disclosed in this embodiment, it is now combined with... Figures 1-10 The locking and unlocking processes for battery 3 are explained below:

[0096] When it is necessary to lock battery 3, first insert the battery base 32 of battery 3 through the mounting port 12 into the mounting base 21, and then rotate it in the R direction with the axis of rotation of the rotating protrusion shaft 213 as the center of rotation, so that battery 3 rotates into the receiving cavity 11, so that the plug hole 321 on the battery base 32 is inserted into the battery plug 211 on the mounting base 21, and the positioning groove 322 on the battery base 32 is inserted into the positioning protrusion 212 on the mounting base 21. During the process of inserting the battery 3 into the receiving cavity 11, the outer wall of the battery 3 will gradually touch and compress the trigger spring 411, and the first protrusion 341 of the battery spring 34 on the top of the battery 3 will touch the locking tongue 44 and drive the locking tongue 44 to move away from the battery 3. At this time, the locking tongue 44 will compress the fourth elastic reset member 45. After the battery 3 is installed in place, the locking tongue 44 presses over the high point of the battery spring 34 (i.e., the first protrusion 341). At this time, the locking tongue 44 is in the fourth elastic reset member Under the action of 45, it moves towards the direction of the battery 3, so that the locking tongue 44 and the first protrusion 341 are locked together on the side facing the mounting port 12, thus completing the first locking of the battery 3 by the locking tongue 44. During the process of the battery 3 being installed into the accommodating cavity 11, the outer wall of the battery 3 will gradually touch and squeeze the trigger spring 411, which will push the locking slide plate 412 to slide along the sliding guide post 13 from the first position to the second position, thereby releasing the locking component 42. At this time, the locking component 42 is reset under the action of the second elastic reset member 43, so that each positioning block 4221 is inserted into the gap between the inner wall of the vehicle tube 1 and the outer wall of the battery 3. At this time, the insertion positioning member 4224 is inserted into the second limiting hole 332 of the battery top seat 33 under the driving action of the driving locking tongue 4223, thereby realizing the locking of the battery 3 by the locking component 42. This is the second locking of the battery 3. Thus, the installation process of the battery 3 is completed.

[0097] When it is necessary to unlock battery 3, insert key 6 into unlocking lock cylinder 51, causing key 6 to rotate unlocking lock cylinder 51. At this time, unlocking connecting horizontal bar 52 and unlocking connecting vertical bar 53 rotate synchronously with unlocking lock cylinder 51. At this time, unlocking connecting vertical bar 53 first abuts against the side of connecting plate body 4211 facing battery 3, and as unlocking connecting vertical bar 53 rotates, it gradually drives connecting plate body 4211 to move away from battery 3, thereby unlocking locking member 422 against battery 3. As unlocking lock cylinder 51 continues to rotate, unlocking connecting horizontal bar 52 can abut against toggle part 542, and drive unlocking lever 54 to rotate around the rotation connection point between connecting part 541 and top seat body 221 as the axis. During the rotation, unlocking lever 54 pushes the pressing post 442, thereby driving the entire locking tongue. 44 moves away from the first protrusion 341, thereby unlocking the latch 44. In addition, since the locking component 42 is in the unlocked state, the locking slide plate 412 can be reset to the first position in the direction closer to the battery 3 under the action of the first elastic reset member 413, thereby locking the locking member 422 in the unlocked state. At this time, the trigger spring 411 can be automatically reset and push the battery 3 towards the mounting port 12. At this time, the limit hook 2211 can engage with the second protrusion 342 to limit the battery 3 from rotating around the axis of the rotating protrusion shaft 213 in the direction away from the vehicle tube 1 to the limit position. At this time, the hand-held pressing part 343 is manually pressed into the clearance hole 333. At this time, the battery spring 34 can undergo slight elastic deformation, thereby separating the limit hook 2211 from the second protrusion 342, so that the battery 3 can be completely removed from the receiving cavity 11.

[0098] This embodiment also provides an electric bicycle, which includes the aforementioned battery locking device, and the frame tube 1 is part of the electric bicycle frame. The electric bicycle provided in this embodiment, by applying the aforementioned battery locking device, can simultaneously achieve the locking and positioning function of the battery 3 and the anti-theft function, preventing the battery 3 from being stolen. It also locks the battery 3 within the frame tube 1, preventing the battery 3 from shaking within the frame tube 1, thus avoiding damage to the battery 3 and poor contact due to shaking, and achieving positioning protection for the battery 3.

[0099] Example 2

[0100] The battery locking device provided in this embodiment is basically the same as that in Embodiment 1. The difference between the battery locking device provided in this embodiment and that in Embodiment 1 is as follows:

[0101] like Figures 11-13As shown, in this embodiment, the locking component 422 includes a positioning pin 4222, which is connected to the connecting plate body 4211. The battery top seat 33 has a first limiting hole 331, and the top seat body 221 has a third limiting hole 2212. When the locking component 42 is in the locked state, the positioning pin 4222 passes through the third limiting hole 2212 and is inserted into the first limiting hole 331, thereby achieving the positioning effect of the battery 3 in the radial direction.

[0102] Example 3

[0103] The battery locking device provided in this embodiment is basically the same as that in Embodiment 1. The difference between the battery locking device provided in this embodiment and Embodiment 1 is as follows:

[0104] In this embodiment, as Figure 14 and Figure 15 As shown, the positioning block 4221 is a wedge-shaped block, and along the radial direction of the battery 3, the maximum size of the wedge-shaped block is greater than the size of the gap, so that the positioning effect of the battery 3 in the radial direction and the axial direction of the battery 3 can be achieved by using only the wedge-shaped block.
