Description

Technical Field

[0001] The utility model relates to the field of electric vehicles, in particular to a vehicle-mounted tube-stored battery. Background Art

[0002] The vehicle-mounted tube-hidden battery means that the battery is installed in a preset battery compartment of the vehicle beam tube, and the battery access port of the battery compartment is covered by a cover to achieve the purpose of hiding the battery in the vehicle beam tube.

[0003] In the prior art, the cover plate covering the battery access port is usually locked by a simple locking mechanism that can be moved and opened from the outside. This means that during use, anyone can easily open the cover plate by simply moving the unlocking member exposed to the outside. This, on the one hand, exposes the cover plate to the risk of theft, and on the other hand, brings potential risks of damage and theft to the batteries installed in the beam tube battery compartment. On the other hand, there is also a potential risk that the cover plate may be opened by pranks or children playing around and not closed in time, resulting in external moisture, dust, foreign matter, etc. entering the beam tube battery compartment and causing unsafe conditions.

[0004] Moreover, the battery installed in the beam tube battery compartment is locked by another locking mechanism. This means that when the battery needs to be removed and taken home for charging or storage, two operations must be performed to release the locking mechanism of the cover and the locking mechanism of the battery respectively before the cover can be opened and the battery can be removed. This greatly increases the complexity of the battery removal operation and causes inconvenience in use.

[0005] Therefore, improvements need to be made by relevant practitioners. Utility Model Content

[0032] The present invention will be further described in detail below with reference to the embodiments given in the accompanying drawings.

[0033] like Figures 1 to 12 As shown, the utility model provides a vehicle-mounted tube-stored battery, including a beam tube 1, a battery 2, a cover plate 3 and a locking mechanism 4. The beam tube 1 is provided with a battery compartment 11, and the battery compartment 11 is provided with a battery access port 12. The battery 2 is loaded into the battery compartment 11 from the battery access port 12, and the cover plate 3 is covered on the battery access port 12 to close the battery compartment 11. The locking mechanism 4 is arranged at one end of the battery compartment 11.

[0034] The end of the battery 2 corresponding to the locking mechanism 4 is provided with a first locking position 21, and the end of the cover 3 corresponding to the locking mechanism 4 is provided with a second locking position 31. The locking mechanism 4 is a linkage lock structure, which includes a first locking member 41, a second locking member 42, and a lock head 43 that cooperates with the first locking member 41 and the second locking member 42. The first locking member 41 and the second locking member 42 are respectively buckled into the first locking position 21 and the second locking position 31, thereby locking the battery 2 and the cover 3. The unlocking operation of the lock head 43 can control the first locking member 41 and the second locking member 42 to disengage from the first locking position 21 and the second locking position 31, respectively, thereby unlocking the battery 2 and the cover 3. At this time, the cover 3 can be opened and the battery 2 can be removed.

[0035] The locking mechanism 4 also includes a linkage member 44 for forming a linkage relationship between the second locking member 42 and the first locking member 41. When the unlocking operation of the lock head 43 controls the first locking member 41 to disengage from the first locking position 21, the linkage member 44 is pushed by the first locking member 41 and triggers the second locking member 42 to disengage from the second locking position 31.

[0036] When the first locking member 41 is moved back and forth, the first locking hook 411 can be disengaged from the first locking position 21, and the lower end of the linkage member 44 can be abutted against the top 441 of the linkage member 44, so that the linkage member 44 rotates and drives the second locking member 42 to rotate, thereby allowing the second locking hook 421 to disengage from the second locking position 31.

[0037] The locking mechanism 4 also includes a first locking member return spring 45 and a second locking member return spring 46. The end of the battery 2 corresponding to the locking mechanism 4 is also provided with a first guide portion 22 located below the first locking position 21. When the battery 2 is inserted into the battery compartment 11, the first guide portion 22 abuts against the first locking hook 411, forcing the first locking member 41 to move backward. Once the first locking hook 411 is aligned with the first locking position 21, the first locking member 41, under the action of the first locking member return spring 45, moves forward and returns to its original position, allowing the first locking hook 411 to engage the first locking position 21. The end of the cover 3 corresponding to the locking mechanism 4 is further provided with a second guide portion 32 located below the second locking position 31. When the cover 3 is closed on the battery access port 12, the second guide portion 32 presses against the second lock hook 421 and forces the second locking member 42 to rotate backward until the second lock hook 421 is aligned with the second locking position 31. The second locking member 42 rotates forward and resets under the action of the second lock member reset spring 46, thereby allowing the second lock hook 421 to buckle into the second locking position 31.

[0038] In addition, the first introduction portion 22 and the second introduction portion 32 are both configured as inwardly inclined guiding slope structures, and the first lock hook 411 and the second lock hook 421 are respectively provided with abutting slopes 4110 and 4210 for the first introduction portion 22 and the second introduction portion 32 to abut, thereby: when the battery 2 is loaded into the battery compartment 11, the first lock hook 411 can be more smoothly guided into the first locking position 21, and when the cover plate 3 is closed on the battery access port 12, the second lock hook 421 can be more smoothly guided into the second locking position 31.

[0039] The lock head 43 is a blade lock or a pin lock, which includes a lock shell 431 and a lock core rotor 432 arranged in the lock shell 431. The lock core rotor 432 is provided with a keyhole 433 along the axial direction. After the matching key 47 is inserted into the keyhole 433, the lock core rotor 432 can be rotated to realize the unlocking operation. A key insertion port 13 is provided on the side wall of the battery compartment 11 at the position corresponding to the lock head 43. The inner end of the lock shell 431 is provided with a slide groove 435 arranged along the moving direction of the first locking member 41. The first locking member 41 is placed in the slide groove 435 and can slide out forward and retract backward. The front end of the slide groove 435 is provided with a front opening 4352 for exposing the front end of the first locking member 41. The lower end of the linkage member 44 abuts the top 441 and extends into the rear part of the slide groove 435 and is opposite to the rear end of the first locking member 41, so that the first locking member 41 can abut the lower end of the linkage member 44 against the top 441 when moving backward. The rear end wall 4351 of the slide groove 435 is provided with a rear opening 4353 for the lower end of the linkage member 44 to extend into the top 441. The inner end of the lock core rotor 432 is provided with a shift block 434 that extends into the slide groove 435, and the first locking member 41 is provided with a contact portion 412 located on the rear side of the shift block 434 and in contact with the shift block 434, so that: on the one hand, the clockwise rotation of the lock core rotor 432 can drive the first locking member 41 to move backward; on the other hand, when the aforementioned first guide portion 22 presses against the first lock hook 411 and forces the first locking member 41 to move backward, the shift block 434 will not block the first locking member 41.

[0040] Of course, in other alternative examples of the present invention, the lock 43 may also be an electronic lock, that is, a smart electronic lock that can be unlocked by fingerprint, password, or mobile phone APP.

[0041] A limiting groove 413 is provided on the rear end surface of the first locking member 41, which is offset from the top 441 of the lower end of the linkage member 44. The first locking member return spring 45 is placed between the limiting groove 413 and the rear end wall 4351 of the slide groove 435, so that the first locking member 41 can return to its original position after the external force disappears.

[0042] The locking mechanism 4 also includes a lock mounting base 48, which is fixed on the bottom wall 111 of the battery compartment 11, and the lock 43 is mounted on the lower part of the lock mounting base 48. The upper part of the lock mounting base 48 is provided with a pivot portion 481 on the side facing away from the battery 2. The linkage member 44 is pivoted to the lower end of the pivot portion 481 through the first pivot 440, and the second locking member 42 is pivoted to the upper end of the pivot portion 481 through the second pivot 420. The second locking member reset spring 46 is arranged between the part of the second locking member 42 below the second pivot 420 and the lock mounting base 48, so that the second locking member 42 can reset forward after the external force disappears.

[0043] Two oblique holes 482 are provided on the lower part of the lock mounting base 48 facing the battery 2, and a spring-loaded support column 483 is inserted into each of the two oblique holes 482. When the battery 2 is installed in the battery compartment 11 and is locked, the spring-loaded support column 483 is pressed by the end of the battery 2 and retracts into the oblique hole 482. When the battery 2 is unlocked, the spring-loaded support column 483 pops outward and forces the end of the battery 2 to tilt upward, which facilitates the removal of the battery after unlocking.

[0044] To facilitate the installation of the lock 43, the lock mounting base 48 includes a base body 48a and a cover plate 48b that cover each other. The cover plate 48b is located on the side of the base body 48a facing the battery 2 and is fixed to the base body 48a by a plurality of first screws 50. The lower end of the base body 48a is provided with a fixing plate 48a3 fixed to the bottom wall 111 of the battery compartment 11 by a plurality of second screws 60. The lower part of the base body 48a is provided with a first opening groove 48a1, and the lower part of the cover plate 48b is provided with a second opening groove 48b1. The first opening groove 48a1 and the second opening groove 48b1 are opposite to each other. A lock head mounting groove 49 is formed, and the lock head 43 is inserted into the lock head mounting groove 49. The inner end of the lock shell 431 is also provided with a connecting ear 4311, and the connecting ear 4311 is fixed together with the base body 48a and the cover plate 48b by a third screw 70. The base body 48a is also provided with a first opening portion 48a2 for exposing the side of the inner end of the lock shell 431 away from the battery 2, so that the lower end of the linkage member 44 can reach the top 441 and extend into the rear part of the slide groove 435. The cover plate 48b is provided with a second opening portion 48b2 for the first lock hook 411 of the first locking member 41 to pass through.

[0045] The second locking position 31 is located on the inner side of the end of the cover plate 3 corresponding to the locking mechanism 4 and is open toward the second locking member 42. A stop protrusion 33 is located on the inner side of the end of the cover plate 3 opposite to the second locking position 31. When the cover plate 3 is closed over the battery access opening 12, the stop protrusion 33 engages with the inner stopper of the corresponding end of the battery access opening 12. Specifically, when the cover plate 3 needs to be closed over the battery access opening 12, the stop protrusion 33 can be first inserted into the inner side of the corresponding end of the battery access opening 12, and then the cover plate 3 can be closed over the battery access opening 12, and the second locking hook 421 can be buckled into the second locking position 31 to achieve locking.

[0046] The above description is only a preferred embodiment of the present invention and should not be used to limit the scope of implementation of the present invention. In other words, simple equivalent changes and modifications made according to the scope of the patent application of the present invention and the content of the utility model description are still within the scope of the present utility model patent.
