Description

Technical Field

[0001] The utility model relates to the technical field of electric vehicles, in particular to a battery box installation device. Background Art

[0002] The existing frame tube lowered battery pack usually uses a locking device to fix the battery pack in the frame tube of the electric vehicle. Since there is a certain angle between the frame tube and the horizontal plane, and the battery pack is only fixed by the locking device, when the user opens the locking device to remove the battery, the battery will be directly separated from the frame tube. If the user does not grasp the separated battery in time, it will cause the battery to fall, thereby causing damage to the battery. In addition, after the battery pack is taken out, the handle of the existing battery pack is usually arranged in a vertical state on the cover of the battery pack, which occupies a lot of space and is not convenient for storage and transportation.

[0003] Therefore, there is an urgent need for a battery box installation device to solve the above technical problems. Utility Model Content

In addition, the terms "first" and "second" are only used to distinguish in the description and have no special meaning.

[0043] like Figure 1-Figure 12As shown, this embodiment provides a battery box installation device, including a base 1, a battery box 2, a locking and ejecting mechanism, and a buffer mechanism. The base 1 is fixedly arranged in the vehicle tube 100 of the electric vehicle, and a fixing seat 11 is provided at one end of the base 1. The battery box 2 is installed in the base 1, and a cover 21 is provided at one end of the battery box 2. A handle 22 is provided on the cover 21 for facilitating lifting the battery box 2, and the handle 22 is rotatably connected to the cover 21 through a rotating shaft 23. Specifically, the two ends of the rotating shaft 23 are respectively penetrated through the two sides of the cover 21, and the handle 22 is rotatably installed on the rotating shaft 23. The handle 22 has a first position perpendicular to the cover 21 and a second position parallel to the cover 21, and a torsion spring 24 is installed on the rotating shaft 23. When the battery box 2 is installed in the base 1, the handle 22 is squeezed by the fixing seat 11 and is in the second position. At this time, the torsion spring 24 has a tendency to rotate the handle 22 to the first position, so that the handle 22 can abut against the surface of the fixing seat 11. The locking and popping mechanism is installed on the base 1. The locking and popping mechanism can lock the battery box 2 in the base 1 and unlock the battery box 2 from the base 1. When the battery box 2 is unlocked from the base 1, the locking and popping mechanism can pop out the end of the battery box 2 close to the cover 21 from the base 1. The buffer mechanism includes a first clamping portion 111 provided on the fixed seat 11 and a second clamping portion 221 provided on the handle 22. When the locking and popping mechanism unlocks the battery box 2 from the base 1 and the battery box 2 pops out from the base 1, the handle 22 is subjected to the force of the torsion spring 24 and can move outward in accordance with the plane of the fixed seat 11 until the second clamping portion 221 is clamped with the first clamping portion 111, thereby preventing the battery box 2 from being directly popped out and causing an accidental fall. When the battery box 2 needs to be taken out, the user only needs to push the handle 22 in the direction close to the second position, so that the second clamping portion 221 can be disengaged from the first clamping portion 111, so that the battery box 2 can be lifted by the handle 22.

[0044] The battery box installation device provided in this embodiment provides a first clamping portion 111 on the fixing seat 11 and a second clamping portion 221 on the handle 22. When the battery box 2 pops out from the base 1, due to the action of the torsion spring 24, the handle 22 always has a tendency to rotate toward the first position (i.e., a position perpendicular to the cover body 21), so that the handle 22 can move outward in line with the plane of the fixing seat 11 until the second clamping portion 221 is clamped with the first clamping portion 111, thereby achieving a buffer for the battery box 2 popping out process and playing a role of secondary locking, effectively preventing the battery box 2 from directly popping out of the base 1 and causing accidental falling and damage.

[0045] Preferably, the first clamping portion 111 of the present embodiment is a clamping tongue provided on the fixing seat 11, and the second clamping portion 221 is a boss provided on the handle 22. The boss and the clamping tongue are engaged with each other to prevent the battery box 2 from completely popping out of the base 1, thereby realizing a secondary locking function for the battery box 2. The structure is simple, the locking is reliable, and the removal operation of the battery box 2 is convenient. Furthermore, the side of the fixing seat 11 facing the battery box 2 is an inclined slope, the bottom of the slope is close to the cover body 21, and the top of the slope is away from the cover body 21. Such a setting provides space for the handle 22 to rotate in the direction close to the first position, and at the same time, after the secondary locking, it is convenient for the user to extend his hand into the space to push and hold the handle 22, so as to realize the smooth and quick removal of the battery box 2.

[0046] In the prior art, there is also a problem that when the battery box 2 is taken out from the base 1, the handle 22 is always perpendicular to the cover 21, resulting in the battery box 2 occupying more space as a whole, which is inconvenient to store and transport. In order to solve this technical problem, the battery box installation device of this embodiment also includes a torsion spring control mechanism, which can realize the transformation of the two working states of the torsion spring 24. The torsion spring control mechanism includes a movable block 25, an abutment block 112 and a first elastic member 26. The movable block 25 is slidably arranged on the cover 21 along the length direction of the battery box 2, the first elastic member 26 is arranged between the movable block 25 and the cover 21, and the abutment block 112 is arranged on the side of the fixed seat 11 facing the cover 21, which is used to abut with the movable block 25; one end of the torsion spring 24 is connected to the handle 22, and the other end is connected to the movable block 25. Specifically, in this embodiment, a slide groove 212 is provided on the cover 21, and buckles 251 are provided on both sides of the movable block 25. The movable block 25 is slidably installed in the slide groove 212 through the buckle 251. Since the two ends of the torsion spring 24 are respectively connected to the movable block 25 and the handle 22, when the position of the movable block 25 changes, the direction of the torsion force applied by the torsion spring 24 to the handle 22 will change. Specifically, when the battery box 2 is installed in the base 1, the abutment block 112 abuts against the movable block 25 to push the movable block 25 to move toward the cover 21. At this time, the torsion spring 24 has a tendency to rotate the handle 22 toward the first position, so that the handle 22 always moves in contact with the fixed seat 11 to ensure the reliability of the first clamping portion 111 and the second clamping portion 221. When the battery box 2 is taken out of the base 1, the movable block 25 is moved away from the cover 21 by the action of the first elastic member 26. At this time, the torsion spring 24 rotates the handle 22 toward the second position, and the handle 22 remains in a position parallel to the cover 21, which is convenient for the storage and transportation of the battery box 2. Of course, when the battery box 2 needs to be lifted, it is only necessary to overcome the force of the torsion spring 24 and flip and lift the handle 22 upwards, which does not affect the normal use of the handle 22.

[0047] Optionally, the first elastic member 26 of the present embodiment is a compression spring, which has a tendency to make the movable block 25 move away from the cover body 21, and has a simple structure and is reliable to use. Further optionally, two torsion springs 24 are provided in the present embodiment, and the two torsion springs 24 are respectively located at the two ends of the rotating shaft 23, and the torsion spring control mechanism is also correspondingly provided with two groups, so that the stability of the movement process of the handle 22 is improved. In other embodiments, the torsion spring 24 and the torsion spring control mechanism can also be provided with one or more groups, which can also realize the above-mentioned functions of the handle 22.

[0048] In this embodiment, a locking portion 211 is further provided on the cover 21, and the locking portion 211 can be specifically a limiting step protruding from the cover 21. The locking and popping mechanism includes a second elastic member 31, a locking assembly, and an unlocking assembly. The second elastic member 31 is arranged in the base 1 and elastically abuts against one end of the bottom side of the battery box 2, and is used to pop up the battery box 2 upward. Preferably, the second elastic member 31 is a spring, which has a simple structure and reliable operation. The locking assembly of this embodiment includes a shell 321 arranged on the base 1, a lock tongue 322 movably arranged on the shell 321, and a third elastic member 323 arranged between the lock tongue 322 and the shell 321. Under the elastic force of the third elastic member 323, the lock tongue 322 can be extended from the shell 321 and cooperate with the locking portion 211, thereby preventing the battery box 2 from popping out, and realizing the locking of the battery box 2 and the base 1. Preferably, the third elastic member 323 of this embodiment is a compression spring, so that the lock tongue 322 always has a movement tendency to extend out of the shell 321.

[0049] The unlocking assembly of this embodiment includes an unlocking member 33 and a linkage member. The unlocking member 33 is connected to the lock tongue 322 through the linkage member. By operating the unlocking member 33, the linkage member can be driven to move, thereby controlling the lock tongue 322 to retract into the housing 321. At this time, the battery box 2 can be ejected from the inside of the base 1 to the outside under the action of the second elastic member 31. Optionally, the unlocking member 33 of this embodiment is a key, and the linkage member is a lock core. The end of the lock core is provided with a protrusion. When unlocking, the protrusion can be driven to rotate by rotating the key. The protrusion drives the lock tongue 322 to overcome the elastic force of the third elastic member 323 and retract into the housing 321 to unlock the battery box 2. In order to achieve smooth movement of the lock tongue 322, the fixing seat 11 of this embodiment is also provided with an avoidance hole 113. When locking the battery box 2, the lock tongue 322 can pass through the avoidance hole 113 and be engaged with the locking portion 211; when unlocking the battery box 2, the lock tongue 322 passes through the avoidance hole 113 and retracts into the housing 321. Of course, in other embodiments, the locking component and the unlocking component may also be configured in other forms and are not limited to this embodiment.

Those skilled in the art will understand that the present invention is not limited to the specific embodiments described herein, and that various obvious changes, readjustments and substitutions can be made by those skilled in the art without departing from the scope of protection of the present invention.
