[0002] In order to make the appearance of the electric bicycle simple, the battery module may be set in the lower tube or tube. However, when the user removes the battery module, the battery module will suddenly fall off without supporting force; if the user is not prepared in advance, the battery module may fall to the ground and be damaged. Summary of the invention

[0003] In order to solve the above problems, an object of the present invention is to provide a battery fixing device and a battery module.

[0004] The present invention provides a battery fixing device, which includes a locking piece, a battery module and an anti-fall component. The locking piece is arranged in the tube body of the frame, and is used for axially docking the battery module. The anti-fall component includes a stopper protruding from the end face of the battery module, a pressing piece located below the stopper, and a telescopic piece longitudinally arranged on the locking piece and a first groove. The pressing piece has a pressing portion, a pivoting portion and a propulsion portion, the pivoting portion is located between the pressing portion and the propulsion portion, and is laterally pivoted on the end face. The telescopic piece is arranged in the first groove, and the telescopic piece forms a protrusion in the axial direction, which has a supporting surface. Wherein, when the battery module moves downward in the locked position, the stopper abuts against the supporting surface to keep the battery module in the unlocked position; when the battery module is in the unlocked position, the pressing portion is used to be pressed toward the battery module to link the propulsion portion to push toward the telescopic piece, so that the stopper is separated from the supporting surface.

[0005] Wherein, the telescopic member includes an elastic member and a block, which is arranged in the first groove and connected to the elastic member, and another part of the block protrudes out of the first groove to serve as the protruding portion.

[0006] Among them, the raised portion also has a first inclined surface and a vertical surface, the stopper has a horizontal surface on one side facing the pressing member and a second inclined surface on the other side, when the battery module moves upward, the second inclined surface contacts the first inclined surface, and the second inclined surface pushes the first inclined surface, so that the block retracts into the first groove until the battery module is located in the locking position, and the telescopic member drives the block to reset, and the support surface is located below the horizontal plane.

[0007] Wherein, the pivot portion is provided with a torsion spring.

[0008] Wherein, at least one spring is arranged between the pressing portion and the end surface.

[0009] Wherein, the battery module further includes an alignment groove longitudinally opened on the end surface, and the alignment groove cooperates with an alignment piece arranged on the locking piece to limit the lateral displacement of the battery module relative to the locking piece.

[0010] Among them, the battery module also includes a second groove, which is opened on the end surface. The second groove corresponds to the locking position and cooperates with a locking tongue arranged on the locking piece. The second groove is located between the alignment groove and the pressing piece, and is used to accommodate the locking tongue so that the relative position of the locking piece and the battery module is fixed.

[0011] In summary, when the battery module of the present invention is docked and locked to the locking member, the retractable member can provide sufficient support force to the stopper to prevent the battery module from falling. Moreover, the pressing member used for unlocking is designed on the battery module instead of the locking member, and the user will instinctively hold the battery module when unlocking, which can avoid the possibility of the battery module falling to the ground due to negligence of the user.

DETAILED DESCRIPTION

[0021] The embodiments of the present invention will be further explained below in conjunction with the accompanying drawings. As much as possible, the same reference numerals represent the same or similar components in the drawings and the specification. In the drawings, the shapes and thicknesses may be exaggerated for simplicity and convenience. It is understood that the components not specifically shown in the drawings or described in the specification are in the form known to those skilled in the art. Those skilled in the art may make various changes and modifications based on the contents of the present invention.

[0022] Please refer to Figure 1 and Figure 2 , which are respectively a schematic diagram of the separation of the battery fixing module of the present invention and a schematic diagram of the connection between the battery module and the battery holder. The battery fixing device includes a locking member 100, a battery module 200 and an anti-fall component. The two 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 arranged at the two ends of the tube body of the electric bicycle, wherein the locking member 100 is used to connect the battery module 200 in the axial direction to lock and support the first end of the battery module 200 (such as Figure 1 As shown), the battery holder 400 carries the second end of the battery module 200 (as shown Figure 2 As shown). The anti-drop component is a plurality of components or structures disposed or formed on the first end of the locking element 100 and the battery module 200; in other words, for the locking element 100 and the battery module 200, the anti-drop component can be an external component independent of the two, or an internal component or structure belonging to the two, and the present invention is not limited thereto. The anti-drop component provides docking, fixing and loosening of the locking element 100 and the battery module 200 in relative position.

[0023] Please refer to Figure 3 , Figure 3It is a partial enlarged schematic diagram of the end face of the battery module in one embodiment. The anti-fall component includes a stopper 300, a pressing member 310, a first groove 110 and a telescopic member 111. The stopper 300 is arranged on the end face 202 of the battery module 200 facing the locking member 100, and the stopper 300 protrudes along the axial direction. The pressing member 310 can be arranged as a whole directly below the stopper 300, or it can be partially located below the stopper 300 and partially located at substantially the same height as the stopper 300, or it can partially pass through the stopper 300 in the longitudinal direction. In other words, as long as the stopper 300 and the pressing member 310 correspond to each other in the longitudinal direction, the present invention does not limit the longitudinal position of the end of the pressing member 310 close to the stopper 300.

[0024] The pressing member 310 has a pressing portion 312, a pivoting portion 314, and a pushing portion 316. The pressing portion 312 is located at an end of the pressing member 310 away from the stopper 300, the pushing portion 316 is located at an end of the pressing member 310 close to the stopper 300, and the pivoting portion 314 is pivoted transversely on the end surface 202 and is located between the pressing portion 312 and the pushing portion 316. When the user unlocks the battery module 200, the pressing portion 312 is used to withstand the force applied by the user, so that the pushing portion 316 moves toward the locking member 100 with the pivoting portion 314 as the axis.

[0025] Please refer to Figure 1 The first groove 110 is longitudinally arranged on the locking member 100, and the telescopic member 111 is arranged in the first groove 110, and a protrusion 112 is formed in the axial direction. When the battery module 200 is axially docked with the locking member 100, the lateral position of the protrusion 112 is the same as or corresponds to the lateral position of the stopper 300 and the pressing member 310. The protrusion 112 has a supporting surface 114, and the supporting surface 114 faces upward.

[0026] In some embodiments, the telescopic member 111 includes an elastic member 1110 and a block 1112, the elastic member 1110 is disposed in the first groove 110, a portion of the block 1112 is located in the first groove 110 and connected to the elastic member 1110, and another portion of the block 1112 protrudes outside the first groove 110 to serve as the protrusion 112. The protrusion 112 also has a first inclined surface 1120 and a vertical surface 1122. The stopper 300 has a horizontal surface 304 on one side facing the pressing member 310 and a second inclined surface 302 on the other side. When the battery module moves upward, the second inclined surface 302 contacts the first inclined surface 1120. The second inclined surface 302 pushes the first inclined surface 1120, so that the block 1112 retracts into the first groove 110. After the battery module 200 is located in the locking position, the elastic member 1110 drives the block 1112 to reset, and the support surface 114 is located below the horizontal surface 304 (such as Figure 4 shown).

[0027] In some embodiments, the second inclined surface 302 faces upward and is located on a side of the stopper 300 different from the pressing member 310, while the horizontal surface 304 faces downward and is located on a side of the stopper 300 facing the pressing member 310. When the battery module 200 is docked with the locking member 100, the second inclined surface 302 is used to contact and push the protrusion 112 of the locking member 100 in the axial direction, and after the protrusion 112 is axially reset, the horizontal surface 304 is used to abut against the supporting surface 114 of the protrusion 112 in the longitudinal direction.

[0028] Please refer to Figure 1 and Figure 3 In some embodiments, the end surface 202 of the battery module 200 is further provided with an alignment groove 320 in the longitudinal direction, and the locking member 100 is provided with an alignment member 170, and the alignment groove 320 and the alignment member 170 cooperate with each other and correspond in the transverse position. When the battery module 200 is docked with the locking member 100, the alignment member 170 can be displaced longitudinally in the alignment groove 320 but not transversely, thereby preventing the battery module 200 from tilting or shifting. Similarly, the end surface 202 can also be provided with an alignment member 170, and the locking member 100 is correspondingly provided with an alignment groove 320 in the longitudinal direction. As long as it is protruding along the axial direction, the alignment member 170 can be in the form of a longitudinally extending long strip or block.

[0029] In some embodiments, the lock member 100 further comprises a lock 150 and a lock tongue 160 (eg, Figure 1As shown in the figure, the end surface 202 is also provided with a second groove 204. The lock 150 is linked to the lock tongue 160 and is used to control the reciprocating movement of the lock tongue 160 in the axial direction. The second groove 204 is arranged between the alignment groove 320 and the pressing member 310, and corresponds to the lock tongue 160. The lock 150, the lock tongue 160 and the second groove 204 are used to provide a second section of locking for the battery module 200. Specifically, when the battery module 200 is docked with the locking member 100 and the raised portion 112 of the elastic sheet is located a distance below the stop member 300, the second groove 204 will accommodate the lock tongue 160 and obtain an upward supporting force, thereby limiting the position of the battery module 200.

[0030] Please refer to Figure 5 and Figure 6 , which is a partial enlarged schematic diagram of the end face of the battery module in different embodiments. In some embodiments, a torsion spring 330 is also provided on the end face 202 of the battery module 200. The torsion spring 330 has a coil portion 332, a fixed end 334 and a torsion end 336 extending from both ends of the coil portion 332, the coil portion 332 and the fixed end 334 are fixed on the end face 202, and the torsion end 336 is fixed in the pivot portion 314. In some embodiments, the battery module 200 also includes at least one spring 340, one end of which is fixed on the end face 202, and the other end corresponds to or is fixed to the pressing portion 312. The spring 340 can be a tension spring, a compression spring or a coil spring. After the pressing portion 312 is subjected to force and the propulsion portion 316 is linked to rotate relative to the pivot portion 314, the pressing portion 312 can be restored to its original position through the torsion spring 330 or the spring 340.

[0031] Next, the process of docking the battery module 200 with the locking member 100 and completing the locking process is described. Figure 7 , Figure 7 The first two actions are Figure 3 The schematic diagram of the AA section, the last two actions are Figure 3 , after the second end of the battery module 200 is placed on the battery holder, the first end of the battery module 200 is docked with the locking member 100 from bottom to top. As the battery module 200 continues to move upward, the protrusion 112 of the telescopic member 111 abuts against the protruding portion of the stopper 300 and gradually retreats toward the first groove 110 in the axial direction until the protrusion 112 no longer abuts against the protruding portion of the stopper 300. The protrusion 112 is reset toward the battery module 200 in the axial direction. Finally, the stopper 300 is located above the protrusion 112 and is firmly pressed downward against the supporting surface 114 of the protrusion 112 by the mass of the battery module 200. This is defined as the unlocked position.

[0032] The battery module 200 and the locking member 100 may also be provided with a second stage of locking, such as the lock 150, the locking tongue 160 and the second groove 204 described in the previous embodiment. As the battery module 200 moves further upward, the stopper 300 no longer abuts against the supporting surface 114 of the protrusion 112, and this is defined as a locked position.

[0033] On the other hand, the locking tongue 160 will abut against the end surface 202 and gradually retreat toward the locking member 100 in the axial direction until the locking tongue 160 and the second groove 204 are at the same level. At this time, the locking tongue 160 no longer abuts against the end surface 202 and returns to the second groove 204 in the axial direction. Finally, the second groove 204 accommodates the locking tongue 160 and is firmly pressed downward on the locking tongue 160 by the mass of the battery module 200.

[0034] Next, the process of unlocking the battery module 200 and disengaging the locking element 100 is described. If the locking element 100 and the battery module 200 are provided with a second stage of locking, the locking tongue 160 needs to be disengaged from the second groove 204 to unlock the second stage of locking before the first stage of locking can be released. Figure 8 , Figure 8 The first two actions are Figure 3 The schematic diagram of the AA section, the last two actions are Figure 3 , the second groove 204 accommodates the lock tongue 160, and the battery module 200 is firmly pressed against the lock tongue 160 by its own mass, which is the second locked state. When the user inserts the key to rotate the lock 150, the lock 150 will drive the lock tongue 160, so that the lock tongue 160 moves back toward the locking member 100 in the axial direction to disengage from the second groove 204. At this time, the battery module 200 will lose the support force provided by the lock tongue 160 and fall off downward. After the battery module 200 moves downward from the locked position, the stopper 300 presses against the support surface 114 of the protrusion 112, so that the battery module 200 is maintained in the unlocked position. Through the synergistic effect of the stopper 300 and the protrusion 112, even if the user does not hold the battery module 200 with another hand during the process of rotating the lock 150, the battery module 200 will still be fixed on the locking member 100, and will not fall to the ground to avoid damage.

[0035] In order to unlock the first stage of the battery module 200, the user must apply force on the pressing portion 312 of the pressing member 310 so that the pushing portion 316 pushes the protruding portion 112 of the telescopic member 111 back toward the first groove 110 until the protruding portion 112 is separated from the stopper 300. This means that the user is likely to instinctively hold the battery module 200 with the left hand and press the pressing portion 312 of the pressing member 310 with the thumb of the left hand. Therefore, even if the battery module 200 loses the support provided by the protruding portion 112 and falls down, the user's left palm will still support the battery module 200. In other words, since the pressing member 310 for unlocking is designed on the end surface 202 of the battery module 200 instead of the locking member 100, the user will instinctively hold the battery module 200 when unlocking; and such a design can effectively reduce the possibility of the battery module 200 falling to the ground due to user negligence.
