DETAILED DESCRIPTION
[0024] The present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.
[0025] Example 1: Figures 1 to 10 As shown, in this embodiment, an anti-falling mechanism for the battery of an electric bicycle tube is provided, including a tube 100, a groove 110 is provided at the bottom of the tube 100, a battery holder 200 matching the groove is fixed in the groove 110, a retractable locking tongue 310 is provided on the inner side of the groove 110, and a locking groove 210 matching the locking tongue and used to prevent the battery holder from falling and pre-supporting, and the surface of the upper inner surface of the locking groove 210 matching the front end of the locking tongue is an inclined surface inclined outward from the inner bottom surface of the locking groove.
[0026] In this embodiment, a latch 120 is fixedly connected to the other inner side surface of the slot 110 , and the end of the battery holder has a slot 220 that matches the latch.
[0027] In this embodiment, the inner bottom surface of the lock slot 210 is further provided with a fixing slot 230 for the lock tongue to be completely inserted and fixed, and the two side surfaces of the fixing slot 230 extend to the two side surfaces of the lock slot and the two side surfaces of the fixing slot exceed the two side surfaces of the lock slot.
[0028] Embodiment 2: On the basis of Embodiment 1, in this embodiment, the side of the lock tongue 310 has a retaining groove 311, and the end of the vehicle tube is fixedly connected to a lock head device 300, and the lock head device includes a lock shell 320, and a lock core 330 is sleeved inside the lock shell 320. The end of the lock core is fixedly connected to a retaining point 340 located in the retaining groove and matched with the retaining groove, and a first spring 350 connected to the lock tongue is fixedly connected inside the lock shell.
[0029] In the locked state, the length of the lock tongue can be 12.1mm. When the key rotates the lock tongue to the unlocked state, the lock tongue shrinks inward. At this time, the length of the lock tongue can be 6.5mm. When the lock tongue is pressed by hand, the lock tongue can shrink inward by 3.5mm. It has an idle stroke. This feature can ensure that after unlocking, the lock tongue is separated from the fixed groove and becomes unlocked. However, the lock tongue can also overcome the gravity of the battery holder to support the battery holder. Then the battery can be pulled down directly by hand. Under the action of pulling force, the lock tongue can also shrink inward by 3.5mm, so that the battery holder can be pulled out. It is simple and convenient.
[0030] In this embodiment, the lower surface of the front end of the lock tongue is an arc surface for facilitating the insertion of the battery holder, the cross-section of the front end of the lock tongue is a right-angled trapezoid, and the upper surface area of the lock tongue is larger than the lower surface of the lock tongue.
[0031] In this embodiment, the cross section of the locking groove is a right-angled trapezoid.
[0032] In this embodiment, when the battery holder is arranged above the vehicle tube 100, in order to facilitate the removal of the battery holder, a slide 130 is provided on the inner side of the groove along the disengagement direction of the battery holder, and a top block 400 is provided in the slide. A second spring 410 for assisting the battery holder to pop out along the disengagement direction of the battery holder is fixedly connected to the top block, and a top groove 240 is provided on the end of the battery holder, which cooperates with the top block and is used to push the battery holder upward under the action of the second spring force after the lock tongue is unlocked.
[0033] When the battery holder is arranged above the vehicle tube 100, when the battery holder is installed, the top groove 240 on the side of the battery holder blocks the top block, compresses and fixes it inward along the slide, and the second spring is compressed; when unlocking, under the elastic force of the second spring, the top block pushes the battery holder along the slide in the direction of the battery holder disengagement, plays an auxiliary pop-up role, which is convenient and quick; when the battery holder is arranged below the vehicle tube 100, preferably, the top block and the second spring do not need to be installed, and the battery holder can be popped down by its own gravity, while preventing the battery holder from falling directly, which is simple and convenient.
[0034] In this embodiment, when unlocking, the key is inserted into the lock core 330 and turned to unlock, driving the lock core 330 and the blocking point 340 to rotate, the blocking point presses the lock tongue 310, driving the lock tongue to move inward, the first spring 350 is compressed, and the lock tongue is released from the fixed groove, thereby achieving the unlocking effect. When the battery holder is located above the vehicle tube, after unlocking, under the elastic force of the originally compressed second spring, the top block pops up the battery holder along the slideway to overcome its own gravity, so that the battery holder can be easily removed. Under the elastic force of the originally compressed second spring 410, the top block 400 pops up the battery holder 200 along the slideway 130; when the battery holder is located below the vehicle tube, preferably, it is not necessary to install the top block and the second spring, and the battery holder can be popped down by its own gravity; at this time, the inclined surface above the lock slot of the battery holder is supported by the lock tongue, and the supporting force of the lock tongue is greater than the gravity of the battery holder itself. At this time, the battery holder is pulled out downward by hand, and the lock tongue 310 retracts inward, so that the battery holder 200 can be removed smoothly; when locking, align the slot at one end of the battery holder with the pin on the inner side of the vehicle tube slot and insert it, and the other end of the battery holder is directly pressed into the vehicle tube slot, and the lock tongue on the other side of the vehicle tube slot 110 retracts inward. As the battery holder is pressed in, the lock tongue first enters the lock slot of the battery holder, and then enters the fixing slot to be completely fixed. The invention has a simple structure and an ingenious design, can effectively prevent the battery holder from directly falling onto the bottom plate under the action of gravity after being unlocked, is safe and reliable, and has practicality and innovation.
