Detailed Description
Embodiments of the present invention will be further illustrated by the following description in conjunction with the associated drawings. Wherever possible, the same reference numbers will be used throughout the drawings and the description to refer to the same or like parts. In the drawings, the shape and thickness may be exaggerated for simplicity and convenience. It is to be understood that components not specifically shown in the drawings or described in the specification are in a form known to those of ordinary skill in the art. Many variations and modifications may be made by one of ordinary skill in the art in light of the disclosure herein.
Fig. 1 and fig. 2 are an assembly view and an assembly schematic diagram of the battery fixing device according to the present application. The battery fixture includes a locking member 100, a battery module 200, and an anti-crash assembly. Both ends of the battery module 200 correspond to the locking member 100 and the battery holder 400, respectively. The locking member 100 and the battery holder 400 are respectively disposed at two ends in the tube of the electric bicycle, wherein the locking member 100 is used for axially abutting the battery module 200 to lock and carry the first end (as shown in fig. 2) of the battery module 200, and the battery pack carries the second end of the battery module 200. The anti-drop assembly is a plurality of assemblies or structures disposed or formed on the first ends of the locking member 100 and the battery module 200; in other words, the anti-falling component may be an external component independent of the locking member 100 and the battery module 200, or an internal component or structure belonging to the two components, which is not a limitation of the present application. The anti-crash assembly provides for docking, securing and releasing of the locking member 100 in relative position with the battery module 200.
The anti-crash assembly is described in detail below. Referring to fig. 3 and 4, schematic diagrams of a battery module 200 and a locking member 100 according to the present application are shown. The drop-resistant assembly includes a track 302, a support 304, and a pintle assembly. Rails 302 are longitudinally open on the end face 202 of the battery module 200 facing the locking member 100, while supports 304 are provided on the locking member 100 and protrude in the axial direction. It should be noted that the positions of the rail 302 and the support 304 are mutually corresponding, so that the support 304 is longitudinally movable within the rail 302 when the end faces 202 of the battery modules 200 are docked to the locking member 100. The pintle assembly includes a resilient member 308 and a movable member 310. The elastic member 308 is laterally disposed on the end face 202 of the battery module 200 and is connected to one end of the movable member 310. The elastic member 308 may include a compression spring, an extension spring, or the like, in a manner that laterally resets the movable member 310. The movable member 310 is disposed laterally on the end face 202 of the battery module 200. The movable element 310 has an inclined surface 3104 and a horizontal surface 3105, the inclined surface 3104 being upwardly directed and the horizontal surface 3105 being downwardly directed. In the unstressed static state of the elastic member 308, the inclined plane 3104 and the horizontal plane 3105 of the movable member 310 both correspond to the track 302, i.e., the blocking track 302; in the deformed state of the elastic member 308, the inclined surface 3104 and the horizontal surface 3105 of the movable member 310 are both laterally deviated from the track 302, i.e., the conducting track 302.
In some embodiments, the end surface 202 is further laterally provided with a placement groove 204 for accommodating the movable member 310 and the elastic member 308. The placing groove 204 intersects with the rail 302 and is communicated with the rail 302, and two ends of the placing groove 204 are respectively provided with a wall surface 2041 and a through hole 2042. The wall 2041 is used for connecting the other end of the elastic piece 308 opposite to the movable piece 310; the through hole 2042 communicates with the external environment, so that one end of the movable member 310 is exposed to the external environment. By such a configuration, the movable member 310 can be displaced in the lateral direction without being offset in the longitudinal direction. However, the present application is not limited to this structure, and the movable member 310 may be a sliding rail (not shown) movably disposed on the end surface 202. In some embodiments, the end surface 202 is further provided with a receiving groove 208 longitudinally, and one end of the receiving groove 208 is communicated with the placing groove 204. With this structure, if one end of the movable member 310 near the through hole 2042 extends out of the end face 202, the movable member 310 can rotate about the lateral direction and receive the extended portion in the receiving groove 208.
In some embodiments, the end face 202 of the battery module 200 is further provided with a positioning slot 210 longitudinally, and the locking member 100 is provided with a protruding positioning member 110. The alignment groove 210 is parallel to the track 302 and corresponds to the position of the alignment member 110. When the battery module 200 is abutted against the locking member 100, the alignment member 110 can move in the alignment groove 210 to prevent the battery module 200 and the locking member 100 from being laterally offset. The alignment member 110 may be a longitudinally extending elongated member that is parallel to the track 302 or may be block-shaped.
In some embodiments, the locking member 100 has a lock 120 and a bolt 122, and the end surface 202 is provided with a groove 212. The lock tongue 122 is interlocked with the lock 120 and corresponds to the position of the groove 212. The recess 212 is configured to receive the locking bolt 122. The lock 120 is configured to move the lock tongue 122 back and forth in the axial direction in a state where a key is inserted and rotated. The second section of the battery module 200 and the locking member 100 can be locked by the cooperation of the locking tongue 122 and the groove 212.
Fig. 5 to 7 are schematic views of the battery module 200 according to the present application during the locking process, respectively, for illustrating the process when the battery module 200 is docked and locked to the locking member 100. It should be noted that fig. 5 to 7 are drawn from a perspective of one side of the locking member 100, along the axial direction and facing the battery module 200, and the locking member 100 and the components disposed on the locking member 100 are both shown in dotted lines for the sake of clarity in illustrating the relative positions of the battery module 200 and the locking member 100. As shown in fig. 5, when the battery module 200 is displaced upward, the supporting member 304 fixed on the locking member 100 is located in the rail 302, and the position of the supporting member 304 with respect to the battery module 200 is as if it is displaced downward. As shown in fig. 6, as the battery module 200 continues to be displaced upward, the inclined surface 3104 of the movable member 310 provided on the end surface 202 abuts against the supporting member 304, and obtains a reaction force from the supporting member 304 to laterally displace and pass through the rail 302, while causing the elastic member 308 connected to one end of the movable member 310 to deform. As shown in fig. 7, after the battery module 200 is further moved upward, the supporting member 304 and the movable member 310 are not supported, and the released elastic member 308 exerts a lateral force on the movable member 310, so that the movable member 310 is reset and the rail 302 is disconnected. Finally, the relative position of the support 304 is below the moveable member 310, which is defined as the locked position. On the other hand, when the battery module 200 is abutted against the locking member 100 and continuously moves upwards, the locking tongue 122 pushed by the end surface 202 is retracted towards the locking member 100 (as shown in fig. 6); until the battery module 200 is in the locked position (as shown in fig. 7), the tongue 122 corresponds to the position of the groove 212 and resets toward the groove 212. Finally, the locking member 100 can lock the battery module 200 from downward displacement of the battery module 200 by providing upward supporting force to the recess 212 by the locking tongue 122.
Fig. 8 to 10 are schematic diagrams of the battery module 200 according to the present application during the unlocking process, respectively, for illustrating the process of unlocking the battery module 200 and gradually disengaging from the locking member 100. The representation of fig. 8 to 10 is the same as that of fig. 5 to 7, and the description of the present application is omitted. As shown in fig. 8, when the battery module 200 is displaced downward, the supporting member 304 fixed on the locking member 100 is located in the rail 302, and the position of the supporting member 304 with respect to the battery module 200 is as if it is displaced upward. As shown in fig. 9, as the battery module 200 continues to displace downward, the horizontal surface 3105 of the movable member 310 provided on the end surface 202 will abut against the support member 304, which is defined as an unlocked position. In the case of the unlocking position, the battery module 200 can be maintained at the same height without falling down by the supporting force provided to the movable member 310 by the supporting member 304. As shown in fig. 10, displacement of the horizontal plane 3105 causes the track 302 to be conducted while the movable member 310 is subjected to a lateral force (shown by an arrow) and moves toward the elastic member 308, so that the support member 304 can pass through the track 302. Eventually, the battery module 200 continues to move downward and disengage the locking member 100 from the tube body to complete unlocking. On the other hand, when the battery module 200 is unlocked and disengaged from the locking member 100, the lock 120 needs to be turned to disengage the locking tongue 122 from the groove 212, and at this time, the battery module 200 will fall down briefly due to the loss of the supporting force of the locking tongue 212, and then will not continue to fall down through the cooperation of the horizontal plane 3105 and the supporting member 304 (as shown in fig. 9). In this way, even if the user does not hold the battery module 200 while turning the lock 120, the battery module 200 remains in the unlocked position and does not fall to the ground.
Fig. 11 and 12 are schematic views of a pintle assembly according to various embodiments of the present application. The movable element 310 includes a pressing portion 3101, a passage portion 3102, a restricting portion 3103, and a connecting portion 3106. The passage portion 3102 and the restriction portion 3103 are both located between the pressing portion 3101 and the connecting portion 3106, wherein the length of the passage portion 3102 in the axial direction is smaller than the length of the restriction portion 3103, and the restriction portion 3103 has a slope 3104 and a horizontal plane 3105 for turning on and off the track. The pressing portion 3101 allows the user to press, and the connecting portion 3106 is used to connect the elastic member 308. The length of the pressing portion 3101 in the axial direction may be longer than the length of the passage portion 3102 (as shown in fig. 11), or may be the same as the length of the passage portion 3102 (as shown in fig. 12). When the battery module 200 is maintained in the unlock position, the pressing portion 3101 can be pressed to move laterally toward the elastic member 308, at which time the horizontal plane 3105 deviates from the rail 302 and causes the rail 302 to conduct. Eventually, as the battery module 200 continues to move downward, the battery module 200 disengages the support 304 and the tube body to complete unlocking. In some embodiments, the pressing portion 3101 extends laterally beyond the end surface 202, which can allow a user to press more easily. However, considering that the space between the battery module 200 and the tube body in the lateral direction may be insufficient when the battery module 200 is accommodated inside the tube body, the pressing portion 3101 may extend out of the end face 202 in the axial direction.
In some embodiments, the wall 2041 has a limiting hole, and the elastic member 308 includes a limiting post 3081 and a spring 3082 sleeved on the limiting post 3081. One end of the limiting post 3081 is fixed to one end of the movable member 310 (as shown in fig. 11), and the other end is correspondingly and movably inserted into the limiting hole 206. The restraining post 3081 can limit the displacement of the movable member 310 in the longitudinal direction and the axial direction and ensure that the movable member 310 is movable only in the lateral direction.
In some embodiments, the wall 2041 is fixedly provided with a limiting post 3081, one end of the movable member 310 is provided with a limiting hole 206 (as shown in fig. 12), and the elastic member 308 is a spring 3082 sleeved on the limiting post 3081. The restraining posts 3081 correspond to the restraining apertures 206 to restrain the movement of the movable member 310 in the longitudinal and axial directions and to ensure that the movable member 310 is movable only in the lateral direction.
The foregoing description is only illustrative of the preferred embodiments of the present application and is not to be construed as limiting the scope of the application, which is defined by the appended claims and their equivalents.
