[0028] Example 1

[0029] Reference Figures 2 to 6, which is the first embodiment of the utility model, provides a battery pack sleeve for electric vehicles. The battery pack sleeve for electric vehicles includes a locking assembly 200, a limiting assembly 300 and a main body assembly 100. The three can cooperate to easily separate the upper sleeve and the lower sleeve. After maintenance is completed, reinstallation is also convenient and quick.

[0030] The locking assembly 200 includes a locking part 201, including a locking frame 201a, a locking block 201b, a knob 201c and a connecting ring 201d. The locking block 201b is set in the locking frame 201a, the knob 201c is fixed to one side of the locking block 201b, and the connecting ring 201d is hinged to one side of the knob 201c.

[0031] The locking parts 201 are divided into two groups. The locking frame 201a is fixed to the top of the lower sleeve 101. A locking groove corresponding to the locking block 201b is provided on the locking frame 201a. By placing the lower sleeve 101 on the bottom of the upper sleeve 102, the locking frame 201a will move to the side of the locking block 201b, and then the knob 201c will be moved. When the knob 201c moves, it will drive the connecting ring 201d to move. At this time, the movement of the connecting ring 201d can simultaneously drive the two knobs 201c to move. The knob 201c drives the locking block 201b to engage with the locking groove, so that the lower sleeve 101 and the upper sleeve 102 can be connected.

[0032] The limiting assembly 300 is arranged on the knob 201c and includes a limiting member 301, including a limiting frame 301a, a limiting block 301b and a support bar 301c. The limiting frame 301a is arranged on one side of the knob 201c, the limiting block 301b is located on one side of the limiting frame 301a, and the support bar 301c is inserted into one side of the limiting block 301b. The support bar 301c and the limiting block 301b are rotatably connected through a rotating shaft.

[0033] A limiting groove corresponding to the limiting block 301b is provided on the limiting frame 301a. When the knob 201c is moved to engage the blocking block 201b with the blocking groove, the limiting block 301b will move on the limiting frame 301a. After the lower sleeve 101 and the upper sleeve 102 are connected, the limiting block 301b can be limited by the setting of the limiting frame 301a to prevent the limiting block 301b from returning to its original position and causing the blocking block 201b to separate from the blocking groove. The support bar 301c is fixed to the inner wall of the knob 201c. The limiting block 301b can be supported by the setting of the support bar 301c to prevent the limiting block 301b from shifting.

[0034] Example 2

[0035] Reference Figures 2 to 6 , which is the second embodiment of the present utility model, and this embodiment is based on the previous embodiment.

[0036] Specifically, the locking assembly 200 further includes a support member 202, which is provided on the locking block 201b. A connecting frame 202a is sleeved on the outer side of the locking block 201b. The locking block 201b and the connecting frame 202a are rotatably connected via a bearing.

[0037] There are two connecting frames 202a, both of which are sleeved on the outside of the card block 201b. The setting of the connecting frames 202a can support the card block 201b and prevent the card block 201b from deflecting.

[0038] Specifically, a first spring 202b is fixed to one side of the knob 201c, a positioning plate 202c is fixed to one end of the first spring 202b, and the positioning plate 202c is fixed to the inner wall of the connecting frame 202a.

[0039] When the knob 201c is moved, a pulling force can be applied to the first spring 202b, and the rebound force of the first spring 202b can drive the knob 201c to return to its original position. The positioning plate 202c is used to support the first spring 202b to prevent the first spring 202b from deflecting.

[0040] Specifically, the limiting assembly 300 further includes a moving member 302 , which is disposed on the limiting block 301 b , and a moving plate 302 a is fixed to one side of the limiting block 301 b .

[0041] When the limiting block 301b needs to be moved to be separated from the limiting groove, the movable plate 302a is moved, and the movement of the movable plate 302a can drive the limiting block 301b to move, thereby moving the limiting block 301b to be separated from the limiting groove.

[0042] Specifically, an inclined plate 302b is provided on one side of the movable plate 302a, and a stopper 302c is fixed on one end of the inclined plate 302b.

[0043] By moving the inclined panel 302b, the inclined panel 302b squeezes the movable plate 302a to make it move, and the movement of the movable plate 302a can drive the limit block 301b to move and separate from the limit groove. The setting of the stop block 302c can limit the movable plate 302a to prevent the inclined panel 302b from moving excessively and causing the movable plate 302a to fall off the inclined panel 302b.

[0044] Specifically, a movable plate 302d is fixed to one side of the inclined plate 302b, and a movable column 302e is fixed to one side of the movable plate 302d.

[0045] The movable column 302e is inserted into one side of the knob 201c, and the movable column 302e is movably connected to the knob 201c. By moving the movable column 302e, the movable column 302e drives the movable plate 302d to move, and the movement of the movable plate 302d can drive the inclined plate 302b to squeeze the movable plate 302a.

[0046] Specifically, a pressing plate 302f is fixed to one end of the movable column 302e, and a fixing plate 302g is sleeved on the outer side of the movable column 302e. The movable column 302e and the fixing plate 302g are movably connected.

[0047] The fixing plate 302g is fixed to the inner wall of the knob 201c. The setting of the fixing plate 302g can support the movable column 302e to prevent the movable column 302e from deflecting. The setting of the pressing plate 302f makes it convenient for the user to press the movable column 302e.

[0048] Example 3

[0049] Reference Figures 1 to 6 , which is the third embodiment of the present utility model, and is based on the first two embodiments.

[0050] Specifically, a pressure plate 302h is sleeved on the outer side of the movable column 302e, and a second spring 302i is fixed to one side of the pressure plate 302h.

[0051] When the movable column 302e is moved, the pressure plate 302h can be driven to move. When the pressure plate 302h moves, it can apply a squeezing force to the second spring 302i. The second spring 302i is fixed to one side of the fixed plate 302g. When the movable column 302e is released, the rebound force of the second spring 302i can drive the movable column 302e to return to its original position.

[0052] Specifically, it also includes a main body component 100, which is arranged on the card frame 201a, including a lower sleeve 101 and an upper sleeve 102. The lower sleeve 101 is fixed to the bottom of the card frame 201a, and the upper sleeve 102 is arranged on the top of the lower sleeve 101.

[0053] The upper sleeve 102 protects the top of the battery pack. During vehicle assembly, it prevents tools and other components from accidentally falling and damaging the battery pack. The lower sleeve 101 bears most of the battery pack's weight and provides support. While the vehicle is in motion, the lower sleeve 101 absorbs the weight of the battery pack and also buffers vibrations and impacts from the road.

[0054] Specifically, a grounding rod 103 is fixed to the bottom of the lower sleeve 101 .

[0055] If the battery pack leaks, the grounding rod 103 can lead the leakage current into the ground, thereby preventing people in the vehicle from getting an electric shock and other parts of the electrical system from being damaged.

[0056] When in use, by placing the lower sleeve 101 on the bottom of the upper sleeve 102, the card frame 201a will move to the side of the card block 201b, and then the knob 201c will be moved. When the knob 201c moves, it will drive the connecting ring 201d to move. At this time, the movement of the connecting ring 201d can simultaneously drive the two knobs 201c to move, and the knob 201c drives the card block 201b to engage with the card slot. When the knob 201c moves, a pulling force can be applied to the first spring 202b. The clamping block 201b is engaged with the clamping slot, so that the lower sleeve 101 and the upper sleeve 102 can be connected. When the knob 201c is moved to engage the clamping block 201b with the clamping slot, the limit block 301b will move on the limit frame 301a. After the lower sleeve 101 and the upper sleeve 102 are connected, the limit block 301b can be limited by the setting of the limit frame 301a to prevent the rebound force of the first spring 202b from driving the limit block 301b to return to its original position and causing the clamping block 201b to separate from the clamping slot.

[0057] When the lower sleeve 101 and the upper sleeve 102 need to be separated, the movable column 302e is driven to move by pressing the pressing plate 302f. When the movable column 302e moves, it can drive the pressure plate 302h to move. When the pressure plate 302h moves, it can apply a squeezing force to the second spring 302i. The movable column 302e drives the movable plate 302d to move. The movement of the movable plate 302d can drive the inclined plate 302b to squeeze the movable plate 302a. The movement of the movable plate 302a can drive the limit block 301b to move, so that the limit block 301b can be moved to separate from the limit slot, and then the limit block 301b is driven to return to its original position by the rebound force of the first spring 202b, so that the card block 201b is separated from the card slot, so that the lower sleeve 101 and the upper sleeve 102 can be separated. After separation, the pressing plate 302f is released, and the movable column 302e can be driven to return to its original position by the rebound force of the second spring 302i.

[0058] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, and all of these should be included in the scope of the claims of the present invention.
