TECHNICAL FIELD
[0001] The utility model relates to the technical field of electric vehicles, in particular to a secondary lock structure of an electric vehicle battery, an electric vehicle battery lock structure and an electric vehicle. BACKGROUND
[0002] The unlocking action of the secondary lock structure of the existing electric vehicle battery is basically achieved by pushing along the length direction of the pipe. When unlocking needs to be performed along the length direction of the pipe, the user is usually used to pushing the unlocking button with the thumb of one hand, and at this time, the thenar eminence area of the hand will be located in the area close to the top of the battery. In order to receive the battery falling after unlocking, the user must use the other hand to cooperate. That is, the secondary lock structure in the prior art needs two hands to successfully achieve the unlocking and receiving of the battery.
[0003] Therefore, when the user cannot simultaneously free two hands, and the unlocking of the battery still needs to be performed, the burden on the user will be increased. UTILITY MODEL CONTENTS
[0004] In order to solve the above technical problems, the utility model provides a secondary lock structure of an electric vehicle battery, which comprises a lock tongue, a guide connected with the lock tongue, and a guide connected with the lock tongue. The adjusting block has an adjusting surface for applying a movement along the axial direction of the pipe to the guide. The plane where the adjusting surface is located is not parallel to the movement direction of the lock tongue. The adjusting surface has a projection in the direction of the movement of the lock tongue. When the adjusting block is moved in the direction of the axial center line of the pipe, the lock tongue can move along the axial direction of the pipe. An elastic member is connected with the guide. When the elastic member is in a natural state, the lock tongue is in a locked state with the battery and the pipe. Therefore, compared with the secondary lock in the prior art, the secondary lock structure of the electric vehicle battery of the utility model has a force application direction of the unlocking action of the battery, which is toward the direction of the axial center line of the pipe, and a force application mode, which is pressing toward the axial center of the pipe. When actually unlocking the battery, the user only needs to apply a force to the adjusting block with the index finger to achieve unlocking. Since the battery will fall downward, the user is used to placing the position of the thenar eminence under the battery, and the pressing direction of the index finger on the adjusting block is consistent with the falling direction of the battery. Therefore, the user pressing the adjusting block with the index finger does not affect the receiving of the falling battery at this time, and thus the unlocking and receiving of the battery can be completed with the same hand, without the need for unlocking with one hand and receiving with the other hand.
[0005] Further, the elastic member is arranged on the side of the guide member away from the lock tongue, and the second lock structure further comprises an abutting wall, and two ends of the elastic member are connected with the abutting wall and the guide member respectively. When an acting force in the direction of the axial center line of the bicycle tube is applied to the adjusting block, the elastic member is in a compressed state, the guide member moves away from the battery, and the lock tongue moves in the same direction with the guide member, so that the second lock is unlocked.
[0006] Further, the adjusting surface is located on the side of the adjusting block away from the lock tongue, and the adjusting surface gradually inclines towards the lock tongue in the direction close to the axial center line of the bicycle tube. Thus, by arranging the adjusting surface in this inclined direction and arranging the elastic member on the side of the guide member away from the lock tongue, the second lock of the battery can be unlocked when an acting force in the direction of the axial center line of the bicycle tube is applied to the adjusting block. The application changes the force direction during unlocking by skillfully arranging the adjusting block structure and cooperating with the guide member, so that the user no longer needs to trigger the unlocking action with the thumb, thereby realizing the effect of single-handed unlocking and holding the battery.
[0007] Further, the adjusting groove for the movement of the adjusting block is arranged in the middle of the guide member, the length of the adjusting groove in the length direction of the bicycle tube is not less than the length of the adjusting block in the same direction, and the adjusting surface can abut against at least part of the groove wall away from the lock tongue. Thus, by arranging the length of the adjusting groove in the length direction of the bicycle tube to be not less than the length of the adjusting block in the same direction, the movement of the guide member is realized by the abutment of the adjusting surface and the groove wall away from the lock tongue when the adjusting block moves in the adjusting groove, thereby realizing the movement of the lock tongue.
[0008] Further, at least one guide protrusion is arranged on the adjusting surface. Thus, only the abutment of the guide protrusion and at least part of the groove wall away from the lock tongue of the adjusting groove is needed to ensure the full application of the pushing force to the adjusting groove while minimizing the friction area, so that the user can save more effort during unlocking.
[0009] Further, a guide groove in the axial direction of the bicycle tube is further included, and the lock tongue and the guide member are contained in the guide groove and can move relative to the guide groove.
[0010] Further, the lock tongue and the guide member are an integral part, and the lock tongue is in the shape of a tongue body arranged on the side of the guide member close to the battery. Thus, only the front end of the guide member needs to be integrally processed into a tongue body shape to be easily processed.
[0011] Further, the secondary lock structure further comprises a button connected with the adjusting block, and an accessory base connected with the handle pipe, wherein the accessory base is provided with a mounting hole for accommodating the button, and the button is movable relative to the accessory base towards a direction close to or away from the axial center line of the handle pipe.
[0012] The utility model also provides a battery lock structure of electric motor car, it includes the secondary lock structure of electric motor car battery beforehand, still include primary lock, and set up on the battery pop -out mechanism of handle pipe.
[0013] The utility model also provides a electric motor car, it includes the secondary lock structure of electric motor car battery or battery lock structure of electric motor car beforehand. BRIEF DESCRIPTION OF DRAWINGS

[0022] The utility model's advantages and characteristics can be more easily understood by the person skilled in the art with the preferred embodiments of the utility model being specifically described in connection with the drawings, so that the protection scope of the utility model can be more clearly and explicitly defined.
[0023] Example 1:
[0024] Referring to Figure 6, this embodiment is a secondary lock structure for an electric vehicle battery, including a locking tongue 1, a guide member 2 connected to the locking tongue 1, an adjusting block 3, and an elastic member 4. The adjusting block 3 has an adjusting surface 31 for applying movement along the axial direction of the vehicle tube to the guide member 2. When the adjusting block 3 is moved towards the axial centerline of the vehicle tube, the locking tongue 1 can move along the axial direction of the vehicle tube. The elastic member 4 is connected to the guide member 2. When the elastic member 4 is in its natural state, the locking tongue 1 is in a locked state with the vehicle tube. Therefore, compared with the secondary locks in the prior art, the secondary lock structure for the electric vehicle battery of this application applies force towards the axial centerline of the vehicle tube for unlocking the battery. Figure 3 and Figure 6 (In the direction of arrow A in the diagram), and the force is applied in the direction of the axial center line of the vehicle tube. When actually unlocking the battery, the user only needs to apply force to the adjustment block 3 with their index finger to unlock it. Since the battery will fall downwards, the user is used to placing the bottom of the battery with the web of their hand. Therefore, pressing the adjustment block 3 with the index finger will not affect the catching of the fallen battery. Thus, the battery can be unlocked and caught with only one hand, without having to use one hand to unlock and the other hand to catch the battery.
[0025] In some embodiments, the elastic element 4 is disposed on the side of the guide 2 away from the latch 1, and the secondary lock structure also includes an abutment wall 51. The two ends of the elastic element 4 are respectively connected to the abutment wall 51 and the guide 2. The adjustment surface 31 is located on the side of the adjustment block away from the latch 1, and the adjustment surface 31 gradually tilts towards the latch 1 in the direction closer to the central axis of the vehicle tube.
[0026] When a force is applied to the adjusting block 3 in the direction of the vehicle tube's axial centerline, the elastic element 4 is compressed, causing the locking tongue 1 to move away from the battery, thus achieving the unlocking effect. In its natural state, the elastic element 4 consistently applies a force to the guide element 2, causing the locking tongue 1 to be inserted into the battery for locking.
[0027] The middle part of the guide piece 2 is provided with an adjusting groove 21 for the movement of the adjusting block 3, the bottom of the adjusting groove 21 is provided with a hollow structure, and the bottom of the adjusting block 3 can pass through the bottom of the adjusting groove 21. The length of the adjusting groove 21 along the length direction of the pipe is not less than the length of the adjusting block 3 in the same direction, and the adjusting surface 31 can abut against at least part of the area of the groove wall of the adjusting groove 21 away from the lock tongue 1. Thus, by making the length of the adjusting groove 21 along the length direction of the pipe not less than the length of the adjusting block 3 in the same direction, when the adjusting block 3 moves in the adjusting groove 21 along the direction towards the axial center line of the pipe, the abutment of the adjusting surface 31 against at least part of the area of the groove wall of the adjusting groove 21 away from the lock tongue 1 (such as the abutment against the upper edge of the groove wall, or the direct abutment against the groove wall) realizes the movement of the guide piece 2 away from the battery, and further realizes the unlocking of the lock tongue 1 from the battery. The trigger action of the unlocking realized by the cooperation of the guide piece 2 and the adjusting block 3 is no longer along the axial direction of the pipe, thus, based on the daily operation habit of people, it is not necessary to use the thumb to push the unlocking button 6, but only the index finger is needed to press the adjusting block 3 towards the axial center of the pipe to realize the unlocking, and the direction of the pressing action is consistent with the direction of the battery falling, thus, the thenar eminence part moves along the direction of the pressing force to receive the battery, and only a single hand is needed to complete the unlocking and receiving actions of the battery.
[0028] In some embodiments, the elastic member 4 is a spring (as shown in the attached Figure 5 figure), and correspondingly, a guide column for sleeving the spring is further provided on the side of the guide piece 2 away from the lock tongue 1. Thus, the movement of the guide piece 2 along with the movement of the adjusting block 3 is more stable. In other possible embodiments, the elastic member 4 can also be a rubber column or a spring sheet, etc., which can realize the locking force of the lock tongue 1 to the battery.
[0029] In some embodiments, at least one guide protruding rib 32 protruding away from the surface of the adjusting surface 31 is further provided (as shown in the attached Figure 4 figure). Thus, only the abutment of the guide protruding rib 32 against the groove wall of the adjusting groove 21 away from the lock tongue 1 is needed to ensure the sufficient application of the pushing force to the adjusting groove 21 while minimizing the friction.
[0030] In other possible embodiments, the elastic member 4 can also be provided on the side of the lock tongue 1 close to the battery, and when the elastic member 4 is in a natural state, the lock tongue 1 always maintains the locking state with the battery, while when unlocking, due to the action force of the adjusting block 3 applied to the guide piece 2 to move away from the battery, the elastic member 4 is stretched to drive the lock tongue 1 to no longer lock with the battery.
[0031] In other possible embodiments, the guide 2 can also be a structure with a guide surface parallel to the adjusting surface 31, the plane of the guide surface being not parallel to the moving direction of the lock tongue 1, and the guide surface having a projection in the moving direction of the lock tongue 1. Thus, the adjusting block 3 and the guide surface of the guide 2 can form a better matching effect.
[0032] In some embodiments, a guide groove 5 along the axial direction of the pipe is further included, and the lock tongue 1 and the guide 2 are accommodated in the guide groove 5 and can move relative to the guide groove 5. The groove wall on the side of the guide groove 5 away from the lock tongue 1 can be the abutting wall 51.
[0033] In some embodiments, the lock tongue 1 and the guide 2 are an integral piece, and the lock tongue 1 is a tongue-shaped structure arranged on the side of the guide 2 close to the battery. Thus, only the front end of the guide 2 needs to be integrally formed into a tongue-shaped structure, which can be easily processed.
[0034] In some embodiments, a button 6 connected with the adjusting block 3 and an accessory base 7 connected with the pipe are further included, and the accessory base 7 is provided with a mounting hole for accommodating the button 6, and the button 6 can move relative to the accessory base 7 towards the direction close to or away from the axial center line of the pipe.
[0035] Embodiment Two:
[0036] The embodiment is a battery lock structure of an electric vehicle, which comprises the secondary lock structure of the battery of the electric vehicle of Embodiment One, further comprises a primary lock 9 and a battery ejection mechanism 8 arranged on the pipe. The battery ejection mechanism 8 has an elastic column 81, and the battery assembly is provided with an ejection hole matched with the elastic column 81. After the primary lock and the secondary lock of the battery are both unlocked, the battery is unlocked and falls off from the pipe under the action of the battery ejection mechanism 8. In combination with the accompanying drawings, the battery assembly is further provided with a locking structure corresponding to the primary lock 9 and the secondary lock, respectively. Figure 6
