[0046] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but cannot be understood as limiting the present invention.

[0047] The battery installation assembly of the embodiment of the utility model has a locked state and an unlocked state. Specifically, the battery installation assembly includes a battery 2. The locked state is a state in which the battery 2 is locked and fixed. At this time, the battery 2 cannot be removed or moved at will. The unlocked state is a state in which the battery 2 is unlocked. At this time, the battery 2 can be removed for charging, etc.

[0048] like Figure 1 As shown, the battery installation assembly of the embodiment of the utility model includes a base member 1, a battery 2, a cover body 3 and a lock 4.

[0049] The base member 1 is provided with an assembly groove. For example, the base member 1 may be a structural member such as a pipe, a frame, a pedal, etc. The base member 1 may be made of metal, plastic, etc. The assembly groove may be generally a rectangular groove. The assembly groove may be provided on the top side of the base member 1, and the notch of the assembly groove may be arranged upward.

[0050] The battery 2 is detachably mounted in the assembly slot, and the cover 3 is independent of the battery 2 and is sealed at the notch of the assembly slot. For example, the battery 2 may be a lithium battery, and the battery 2 may be composed of a plurality of single cells. In some other embodiments, the battery 2 may also be a graphene battery, a lead-acid battery, etc. During assembly, the battery 2 may be directly placed in the assembly slot from the notch of the assembly slot.

[0051] like Figure 1 As shown, the cover 3 can be a flat plate as a whole. In some other embodiments, the cover 3 can also have a certain arc shape, so as to improve the fit with the outer surface of the base 1. The cover 3 can be made of plastic, metal, etc. After the battery 2 is assembled in the assembly groove, the cover 3 can be installed at the notch of the assembly groove. The notch of the assembly groove can be sealed by the cover 3, thereby avoiding the battery 2 from being exposed to the outside, ensuring the overall appearance and improving the protection effect.

[0052] The lock 4 includes a first locking tongue 41 and a second locking tongue 42. In the locked state, the first locking tongue 41 locks the cover body 3 at the notch, and the second locking tongue 42 locks the battery 2 in the assembly groove. In the unlocked state, the first locking tongue 41 releases the lock on the cover body 3, and the second locking tongue 42 releases the lock on the battery 2.

[0053] For example, Figure 1 and Figure 2 As shown, the lock 4 can be installed on the front side of the assembly groove, and the lock 4 has two locking tongues, which are the first locking tongue 41 and the second locking tongue 42. The first locking tongue 41 and the second locking tongue 42 can extend along the front-to-back direction and can reciprocate relative to the base member 1 in the front-to-back direction.

[0054] When the battery 2 and the cover 3 are assembled on the base 1, the first locking tongue 41 and the second locking tongue 42 can be driven to move backward. At this time, the first locking tongue 41 can be plugged and matched with the cover 3, so that the cover 3 can be locked at the notch of the above-mentioned assembly groove, and the second locking tongue 42 can be plugged and matched with the battery 2, so that the battery 2 can be locked in the assembly groove. Figure 1 shown.

[0055] When the battery 2 needs to be removed from the base 1, the first locking tongue 41 and the second locking tongue 42 can be driven to move forward. At this time, the first locking tongue 41 can release the lock on the cover 3, so that the cover 3 can be removed from the notch of the assembly groove. Secondly, the second locking tongue 42 can also release the lock on the battery 2, so that the battery 2 can be removed from the assembly groove. Figure 2 shown.

[0056] It should be noted that, in the process of switching from the locked state to the unlocked state, the release of the lock of the cover 3 by the first lock tongue 41 does not lag behind the release of the lock of the battery 2 by the second lock tongue 42 .

[0057] For example, the movement of the first locking tongue 41 and the second locking tongue 42 may be synchronous, and in the process of driving the battery installation assembly to switch to the unlocked state, the first locking tongue 41 and the second locking tongue 42 may move forward synchronously, and the first locking tongue 41 and the second locking tongue 42 may respectively release the locks on the cover body 3 and the battery 2 at the same time. In other embodiments, the release of the lock of the cover body 3 by the first locking tongue 41 may also precede the release of the lock of the battery 2 by the second locking tongue 42.

[0058] In some other embodiments, the movement of the first locking tongue 41 and the second locking tongue 42 may also be performed asynchronously. For example, after the first locking tongue 41 completes locking or unlocking the cover body 3, the second locking tongue 42 then completes locking or unlocking the cover body 3.

[0059] In the battery installation assembly of the embodiment of the utility model, the cover body 3 is locked and fixed by the first locking tongue 41, and the battery 2 is locked and fixed by the second locking tongue 42. This double locking fully ensures the reliability of the locking, thereby ensuring the stability of the assembly of the battery 2 and improving the safety of use.

[0060] Secondly, since the cover body 3 is independently arranged from the battery 2, when the battery 2 is out of power, the battery 2 can be removed and charged, and the cover body 3 can still seal the notch of the assembly slot and ensure the overall appearance. Secondly, it also allows the user to go out for riding without assembling the battery 2, which improves the flexibility and convenience of use.

[0061] In some embodiments, the battery installation assembly includes a first driving member 5, which is disposed on the base member 1, and is used to push at least part of the cover body 3 away from the slot after the first locking tongue 41 releases the lock on the cover body 3.

[0062] For example, Figure 1 and Figure 2As shown, the first driving member 5 can be fixed on the base member 1, and the first driving member 5 can be a spring sheet, etc., and a part of the first driving member 5 can be in abutment contact with the cover body 3. When the first locking tongue 41 releases the lock on the cover body 3, the elastic potential energy of the first driving member 5 can be released, and the cover body 3 can be pushed away from the notch of the assembly groove by the first driving member 5, which plays a role of self-separation of the cover body 3 and the base member 1, thereby facilitating the user to remove the cover body 3 from the notch of the assembly groove.

[0063] In some embodiments, one side of the cover body 3 is rotatably connected to the base member 1, the first driving member 5 is disposed on the other side of the cover body 3 opposite to the rotating connection between the cover body 3 and the base member 1, and the first locking tongue 41 and the first driving member 5 are located on the same side of the cover body 3.

[0064] For example, Figure 1 and Figure 2 As shown, the rear side of the cover body 3 can be hinged or pivotally connected to the base member 1, and the first driving member 5 can be arranged on the front side of the cover body 3 and can be located below the cover body 3. As a result, the force arm between the first driving member 5 and the rotating assembly of the cover body 3 can be longer, so that the cover body 3 has a larger opening and closing angle relative to the base member 1 when being pushed away from the base member 1, further improving the convenience of disassembling the cover body 3.

[0065] It should be noted that the first locking tongue 41 can also be arranged on the front side of the battery 2. Since the force arm at the rotational assembly point between the first locking tongue 41 and the cover body 3 is longer, the first locking tongue 41 can lock the cover body 3 by applying a smaller force, which also meets the need to lock and fix the front and rear sides of the cover body 3.

[0066] In some embodiments, the cover 3 is provided with a first hook 31 , which is provided on a side of the cover 3 facing the battery 2 . In the locked state, the first hook 31 is fixedly hooked with the base 1 , and the first hook 31 is rotatable relative to the base 1 .

[0067] For example, Figure 1 and Figure 2 As shown, the first hook 31 can be integrally formed on the bottom surface of the cover body 3 and adjacent to the rear side of the cover body 3. The first hook 31 can be generally L-shaped, and a slot can be provided on the base member 1. During assembly, a portion of the first hook 31 can be inserted into the slot, thereby achieving assembly and fixation of the first hook 31 and the base member 1.

[0068] Secondly, since the first hook 31 and the base member 1 are movably assembled, the first hook 31 can rotate freely relative to the base member 1, thereby meeting the need to lift the front side of the cover body 3 by the first driving member 5 and also meeting the need to remove the cover body 3 from the base member 1.

[0069] In some embodiments, the cover body 3 is provided with a second hook 32, which is provided on the side of the cover body 3 facing the battery 2. In the locked state, the second hook 32 is hooked and fixed with the first locking tongue 41, and in the unlocked state, the first locking tongue 41 releases the hook lock on the second hook 32.

[0070] For example, Figure 1 and Figure 2 As shown, the second hook 32 can be integrally formed on the bottom surface of the cover body 3 and adjacent to the front side of the cover body 3, and the second hook 32 can be a straight hook shape as a whole. When in use, the first locking tongue 41 can be hooked and fixed with the second hook 32, so that the front side of the cover body 3 can be locked and fixed.

[0071] The second hook 32 can reduce the height difference between the cover body 3 and the first locking tongue 41 for fixing the connection, thereby facilitating the position limiting cooperation between the two. On the other hand, the second hook 32 and the first locking tongue 41 can be shielded by the cover body 3, thereby ensuring the appearance and the connection effect.

[0072] In some embodiments, the battery installation assembly includes a second driving member 6, which is disposed on the lock 4 and / or the base member 1, and after the second locking tongue 42 releases the lock on the battery 2, the second driving member 6 is used to push at least part of the battery 2 out of the assembly slot.

[0073] For example, Figure 1 and Figure 2 As shown, the second driving member 6 can be arranged on the lock 4. In some other embodiments, the second driving member 6 can also be arranged on the base member 1. The second driving member 6 can be a linear drive, a spring, etc. When the battery 2 is assembled in the assembly groove, the second driving member 6 can be pressed on the bottom side of the battery 2. When the second locking tongue 42 releases the lock on the battery 2, the second driving member 6 can push the battery 2 upward and can push the front half of the battery 2 out of the notch of the assembly groove, thereby facilitating the user to remove the battery 2 from the assembly groove.

[0074] In some embodiments, one side of the battery 2 is rotationally connected to the base 1, the second driving member 6 is arranged on the other side of the battery 2 opposite to the rotational connection between the battery 2 and the base 1, and the second locking tongue 42 and the second driving member 6 are located on the same side of the battery 2.

[0075] For example, Figure 1 and Figure 2 As shown, the rear side of the battery 2 can be hinged or pivotally connected to the base member 1, and the second driving member 6 can be arranged on the front side of the battery 2 and can be located below the battery 2. As a result, the force arm between the second driving member 6 and the rotating assembly of the battery 2 can be longer, so that the battery 2 has a larger opening and closing angle relative to the bottom of the assembly groove when it is pushed out of the assembly groove, further improving the convenience of removing the battery 2.

[0076] It should be noted that the second locking tongue 42 can also be arranged on the front side of the battery 2. Since the force arm at the rotational assembly point between the second locking tongue 42 and the battery 2 is longer, the second locking tongue 42 can lock the battery 2 by applying a smaller force, which also meets the need to lock and fix the front and rear sides of the battery 2.

[0077] In some embodiments, one of the battery 2 and the base 1 is provided with a pivot slot 11 , and the other is provided with a pivot portion 21 , at least a portion of the pivot portion 21 is embedded in the pivot slot 11 so that the battery 2 can rotate relative to the base 1 .

[0078] For example, Figure 1 and Figure 2 As shown, the pivot groove 11 may be provided with a rear side wall of the battery 2, the pivot groove 11 may be a groove with a semicircular cross section, and the pivot groove 11 generally extends in the left-right direction. The pivot portion 21 may be integrally formed on the rear groove wall of the assembly groove, the pivot portion 21 extends in the left-right direction, and the cross section of the pivot portion 21 may be semicircular.

[0079] During assembly, the pivot portion 21 can be embedded in the pivot groove 11. The blocking cooperation between the pivot portion 21 and the pivot groove 11 can meet the need of limiting the rear assembly of the battery 2 on the one hand, and on the other hand, the battery 2 can be rotated around the axis of the pivot portion 21, thereby meeting the need of pushing the front half of the battery 2 out of the assembly groove by the second driving member 6.

[0080] In some embodiments, the second driving member 6 is provided on the lock 4 and includes a hook body 61 and a first elastic member 62. The hook body 61 is rotatably assembled on the lock 4. The first elastic member 62 acts between the hook body 61 and the lock 4. The first elastic member 62 is used to apply an elastic force to the hook body 61 so that the hook body 61 always has a movement tendency to push the battery 2 out of the assembly slot.

[0081] For example, Figure 3 As shown, the second driving member 6 can be assembled on the lock 4, the hook body 61 can be in a curved hook shape, and the first elastic member 62 can be a torsion spring, etc. The hook body 61 can be assembled on the lock 4 by pivoting, the first elastic member 62 can be sleeved on the outer peripheral side of the pivot, and one end of the first elastic member 62 can be in abutment contact with the lock 4, and the other end of the first elastic member 62 can be in abutment contact with the hook body 61.

[0082] When the battery 2 is placed in the assembly slot, the battery 2 can press down the hook body 61, at which time the first elastic member 62 will be compressed and store energy. When the second locking tongue 42 releases the lock on the battery 2, the hook body 61 will swing upward under the action of the first elastic member 62, and the swinging hook body 61 can push the battery 2 upward, thereby meeting the need to push the battery 2 out of the assembly slot.

[0083] In some embodiments, the battery 2 is provided with a stopper 22, for example, Figure 1 and Figure 2 As shown, the stopper 22 can be integrally formed on the front side of the battery 2, and the stopper 22 can be a convex block located on the front side of the battery 2. In the locked state, the free end of the hook body 61 is located below the stopper 22 and contacts the stopper 22. Thus, the assembly of the hook body 61 and the battery 2 is facilitated.

[0084] In some embodiments, the lock 4 includes a housing 43 , a lock core 44 , an eccentric member 47 , a second elastic member 45 and a third elastic member 46 .

[0085] The first locking tongue 41 and the second locking tongue 42 are both slidably assembled in the housing 43. Figure 4 and Figure 5 As shown, the first locking tongue 41 and the second locking tongue 42 both extend substantially in the front-to-back direction, and two slide grooves may be provided in the housing 43, and the two slide grooves may be arranged at intervals in the up-down direction and both extend in the front-to-back direction. The first locking tongue 41 may be slidably mounted in the upper slide groove and may extend from the rear side of the housing 43, and the second locking tongue 42 may be slidably mounted in the lower slide groove and may extend from the rear side of the housing 43.

[0086] The eccentric member 47 is connected to the lock core 44 and can rotate synchronously with the lock core 44. The outer peripheral wall of the eccentric member 47 stops at the first lock tongue 41 and / or the second lock tongue 42 so that when the lock core 44 rotates, the first lock tongue 41 and the second lock tongue 42 can be driven to retract into the shell 43 and release the lock of the cover body 3 and the battery 2 respectively.

[0087] For example, Figure 6 As shown, the lock core 44 can be fixed on the shell 43, the eccentric piece 47 can include an eccentric shaft, the axial direction of the eccentric piece 47 can be left and right directions, the eccentric piece 47 can be assembled in the shell 43, the left end of the eccentric piece 47 can be connected to the lock core 44, and the right end of the eccentric piece 47 can extend between the first lock tongue 41 and the second lock tongue 42.

[0088] When in use, the lock core 44 can drive the eccentric piece 47 to rotate. Since the eccentric shaft of the eccentric piece 47 is of variable diameter, it can stop the first lock tongue 41 and the second lock tongue 42 forward under the rotation of the eccentric piece 47, thereby realizing the sliding drive of the first lock tongue 41 and the second lock tongue 42, and then facilitating the first lock tongue 41 and the second lock tongue 42 to release the locking limit of the cover body 3 and the battery 2 respectively.

[0089] The second elastic member 45 acts between the first locking tongue 41 and the housing 43, and the second elastic member 45 is used to reset the first locking tongue 41 and keep the first locking tongue 41 at the position of locking the cover 3. Figure 5 and Figure 6 As shown, the second elastic member 45 can be a spring, which can be assembled in the housing 43 and can be located on the left side of the first locking tongue 41. The second elastic member 45 can always apply an elastic force to the first locking tongue 41 to move backward.

[0090] The third elastic member 46 acts between the second locking tongue 42 and the housing 43, and the third elastic member 46 is used to reset the second locking tongue 42 and keep the second locking tongue 42 at a position to lock the battery 2. Figure 5 and Figure 6 As shown, the third elastic member 46 can also be a spring. The third elastic member 46 can be assembled in the housing 43 and can be located on the left side of the second locking tongue 42. The third elastic member 46 can always apply an elastic force to the second locking tongue 42 to move backward.

[0091] When it is necessary to lock the cover body 3 and the battery 2, the eccentric piece 47 can be driven to rotate by rotating the lock cylinder 44 again. At this time, the stop of the eccentric piece 47 on the first lock tongue 41 and the second lock tongue 42 can be released, wherein the first lock tongue 41 can slide backward and extend out of the shell 43 under the action of the above-mentioned second elastic member 45, and the second lock tongue 42 can slide backward and extend out of the shell 43 under the action of the above-mentioned third elastic member 46, and the cover body 3 and the battery 2 can be locked and fixed respectively by the extended first lock tongue 41 and the second lock tongue 42.

[0092] In some embodiments, the first locking tongue 41 is provided with a first stopping portion 411, and the second locking tongue 42 is provided with a second stopping portion 421. The first stopping portion 411 is used to stop and contact with the second stopping portion 421 so that the eccentric member 47 can drive the first locking tongue 41 and the second locking tongue to retract synchronously into the shell 43.

[0093] For example, Figure 5 As shown, the first stopper 411 can be integrally formed on the bottom side of the first locking tongue 41, and the second stopper 421 can be integrally formed on the top side of the second locking tongue 42, wherein the second stopper 421 can be located at the rear side of the first stopper 411. The eccentric shaft of the eccentric member 47 can be located at the rear side of the second stopper 421.

[0094] When in use, the rotating eccentric piece 47 can stop on the second stop portion 421, so that the second lock tongue 42 can be driven forward. By means of the stop cooperation between the first stop portion 411 and the second stop portion 421, the first lock tongue 41 can also move forward synchronously with the second lock tongue 42, thereby meeting the need for synchronous unlocking of the first lock tongue 41 and the second lock tongue 42.

[0095] In addition, since the first stopping portion 411 is always stopped by the second stopping portion 421, during the process of switching to the locked state, the movement of the first locking tongue 41 will always be restricted by the second locking tongue 42. Therefore, the second locking tongue 42 can first lock the battery 2, and then the first locking tongue 41 will lock and fix the cover body 3, avoiding the situation where the cover body 3 has been locked and fixed but the battery 2 has not been locked, thereby ensuring the locking effect.

[0096] In some embodiments, Figure 5 As shown, the length of the first locking tongue 41 extending out of the housing 43 is shorter than the length of the second locking tongue 42 extending out of the housing 43, thereby preventing the battery 2 from being easily blocked by the first locking tongue 41 during removal from the assembly slot.

[0097] In some embodiments, the housing 43 is provided with a limiting portion 431, and the limiting portion 431 and the second stopping portion 421 are stopped to limit the travel of the first locking tongue 41 and the second locking tongue 42 extending from the housing 43. Figure 5 and Figure 6 As shown, the limiting portion 431 can be integrally formed in the shell 43 , and the limiting portion 431 can be a columnar structure and can extend along the left-right direction.

[0098] The second stopping portion 421 can be stopped and limited by the limiting portion 431, so that the first stopping portion 411 can also be stopped and limited, thereby limiting the length of the first locking tongue 41 and the second locking tongue 42 extending out of the shell 43, avoiding the first locking tongue 41 and the second locking tongue 42 from escaping from the shell 43, and ensuring the stability of the assembly.

[0099] In some embodiments, a pad 33 is provided on the side of the cover 3 facing the battery 2. In the locked state, the pad 33 is pressed against the battery 2 and used for buffering and shock reduction. Figure 1 and Figure 2 As shown, the pad body 33 can be embedded in the bottom side of the cover body 3 and arranged near the front side of the cover body 3. The material of the pad body 33 can be foam or the like.

[0100] When the cover body 3 is locked and fixed by the first locking tongue 41, the pad body 33 can be clamped and fixed between the cover body 3 and the battery 2. On the one hand, it can fill the assembly gap between the cover body 3 and the battery 2 to ensure the compactness of the overall structure. On the other hand, the pad body 33 can play a buffering role, thereby achieving the effect of shock absorption and noise reduction.

[0101] In some embodiments, at least one first locking tongue 41 is provided, and at least one second locking tongue 42 is provided. Figure 5 and Figure 6As shown, each of the first locking tongue 41 and the second locking tongue 42 can be provided with one. In some other embodiments, each of the first locking tongue 41 and the second locking tongue 42 can also be provided with multiple ones.

[0102] In some embodiments, the first locking tongue 41 and the second locking tongue 42 are located on the same side of the battery 2. Figure 1 and Figure 2 As shown, the first locking tongue 41 and the second locking tongue 42 can both be located on the front side of the battery 2. In some other embodiments, the first locking tongue 41 and the second locking tongue 42 can also be located on different sides of the battery 2, thereby further ensuring the stability of locking.

[0103] In some embodiments, the locking stroke of the first locking tongue 41 and the cover body 3 is shorter than the locking stroke of the second locking tongue 42 and the battery 2. For example, the first locking tongue 41 and the second locking tongue 42 can be plugged into and matched with the cover body 3 and the battery 2 respectively, wherein the locking stroke of the first locking tongue 41 can be regarded as the plug-in fitting depth of the first locking tongue 41 and the cover body 3, and the locking stroke of the second locking tongue 42 can be regarded as the plug-in fitting depth of the second locking tongue 42 and the battery 2.

[0104] Therefore, in the process of switching to the unlocked state, the first lock tongue 41 can first release the lock on the cover body 3, and then the second lock tongue 42 will be completely moved out of the corresponding slot of the battery 2 and release the lock on the battery 2, thereby meeting the need to successively release the lock on the cover body 3 and the battery 2.
