As used herein, the term "and / or" includes any and all combinations of one or more of the associated listed items.

[0035] In order to better understand the technical solutions and beneficial effects of the present disclosure, the present disclosure will be further described in detail below in conjunction with specific embodiments:

[0036] Please refer to Figure 1The battery pulling structure of one embodiment comprises a shell 100, two limiting fences 200 and a pulling assembly 300. The outer side of the shell 100 is provided with a flat palm stretching area 101. The two limiting fences 200 are arranged on the flat palm stretching area 101 and are fixedly connected to the shell 100 respectively. The two limiting fences 200 are spaced from each other and form a limiting and containing groove 201. The pulling assembly 300 is arranged on the outer side of the shell 100 and the two ends of the pulling assembly 300 are fixedly connected to the shell 100 respectively. The middle of the pulling assembly 300 has a movable gripping part which is movably contained in the limiting and containing groove 201. Each limiting fence 200 is provided with a finger passing gap 202 which corresponds to one side of the movable gripping part and is in communication with the limiting and containing groove 201. The finger passing gap 202 is used for the fingers to pass through to pull the movable gripping part.

[0037] It can be understood that, since the two ends of the pulling assembly 300 are fixedly connected to the shell 100 and the movable gripping part of the pulling assembly 300 is movably contained in the limiting and containing groove 201 formed between the two limiting fences 200, the movable gripping part can be contained in the limiting and containing groove 201 so as to be constrained at the taking and placing position, thereby reducing the random swinging and shaking of the movable gripping part. Since the two limiting fences 200 are arranged on the flat palm stretching area 101 and the finger passing gap 202 of each limiting fence 200 is in communication with the limiting and containing groove 201 and corresponds to one side of the movable gripping part, the flat palm stretching area 101 can provide more space for the hand, thereby making it more convenient for the fingers to be inserted into the finger passing gap 202 so that the two sides of the movable gripping part can be quickly gripped and pulled up, and finally improving the convenience of gripping the pulling assembly 300 by the hand.

[0038] Please refer to Figure 1 In some embodiments, the two finger passing gaps 202 are oppositely arranged. It can be understood that, when the palm is stretched towards the pulling assembly 300 on the flat palm stretching area 101, one part of the fingers on the palm contacts one side of the movable gripping part through the finger passing gap 202 and the other part of the fingers on the palm contacts the other side of the movable gripping part through the finger passing gap 202. Since the two finger passing gaps 202 are oppositely arranged, the two parts of the fingers form a gripping force on the opposite sides of the movable gripping part, so as to more stably grip and pull up the movable gripping part.

[0039] Please refer to Figure 2In some embodiments, the limiting fence 200 has at least two stop protrusions 210; each stop protrusion 210 is fixedly arranged on the flat palm area 101 and arranged along the length direction of the pulling assembly 300; the gap between two adjacent stop protrusions 210 forms a finger passing gap 202. It can be understood that, since the pulling assembly 300 is arranged along the length direction of the pulling assembly 300, the pulling assembly 300 can be effectively blocked to more effectively limit the movement range of the pulling assembly 300. At the same time, by forming the finger passing gap 202 between two adjacent stop protrusions 210, the movable gripping part can be quickly gripped.

[0040] Please refer to Figure 1 With Figure 2 In some embodiments, the pulling assembly 300 includes a soft gripping belt 310 and two fixed supports 320; each fixed support 320 is fixedly arranged on the outer side of the shell 100, and the positions of the two fixed supports 320 are opposite; the middle part of the soft gripping belt 310 is movably accommodated in the limiting groove 201, and each end of the soft gripping belt 310 is movably mounted on one fixed support 320. It can be understood that, since each end of the soft gripping belt 310 is movably mounted on one fixed support 320, and each fixed support 320 is fixedly arranged on the outer side of the shell 100, the soft gripping belt 310 can be closely connected with the shell 100. At the same time, the soft gripping belt 310 can be deformed and flexible to separate from the limiting groove 201 under tension to pull up the entire battery pack. Specifically, the soft gripping belt 310 can be a woven belt or other soft belt with flexibility.

[0041] Please refer to Figures 2 to 4 In some embodiments, at least one supporting unit 110 is fixedly arranged on the outer side of the shell 100; each supporting unit 110 is arranged at the position of one fixed support 320; each supporting unit 110 includes two supporting bosses 1110; the end of the soft gripping belt 310 forms a movable sleeve hole 3101; the fixed support 320 is a pressure bearing pull rod 3210; the pressure bearing pull rod 3210 movably penetrates the movable sleeve hole 3101; each end of the pressure bearing pull rod 3210 is fixedly connected to one supporting boss 1110 in the same supporting unit 110. It can be understood that, since the fixed support 320 is a pressure bearing pull rod 3210, the pressure bearing pull rod 3210 movably penetrates the movable sleeve hole 3101, and each end of the pressure bearing pull rod 3210 is fixedly connected to one supporting boss 1110 in the same supporting unit 110, when the pressure bearing pull rod 3210 penetrates the movable sleeve hole 3101, the movable sleeve hole 3101 can move relative to the pressure bearing pull rod 3210, thereby reducing the movement restriction on the soft gripping belt 310, and finally adjusting the position of the soft gripping belt 310 to store or pull out the soft gripping belt 310 from the limiting groove 201.

[0042] Please refer to Figure 2With Figure 4 In some embodiments, an active gap 1011 is provided between two supporting bosses 1110 in the same supporting unit 110, and the part of the end of the soft lifting belt 310 is located in the active gap 1011, and the inner diameter of the active sleeve hole 3101 is larger than the diameter of the pressure-bearing pull rod 3210. It can be understood that, since the inner diameter of the active sleeve hole 3101 is larger than the diameter of the pressure-bearing pull rod 3210, the part of the end of the soft lifting belt 310 is located in the active gap 1011, so that the end of the soft lifting belt 310 can be displaced relative to the pressure-bearing pull rod 3210 to move more freely in the active gap 1011, and finally further improve the flexibility of the adjustment of the soft lifting belt 310.

[0043] Please refer to Figure 4 In some embodiments, the contact surface between the rod wall of the pressure-bearing pull rod 3210 and the hole wall of the active sleeve hole 3101 is a rounded arc surface. It can be understood that, since the contact surface between the rod wall of the pressure-bearing pull rod 3210 and the hole wall of the active sleeve hole 3101 is a rounded arc surface, the friction between the hole wall of the active sleeve hole 3101 and the pressure-bearing pull rod 3210 when the soft lifting belt 310 is active can be reduced, thereby achieving the effect of increasing the service life of the soft lifting belt 310.

[0044] Please refer to Figure 5 With Figure 6 In some embodiments, the battery lifting structure further comprises a tooth fastening assembly 400, the tooth fastening assembly 400 comprising a tooth screw 410 and a fastening nut 420; the fastening nut 420 is arranged on the inner side of the shell 100 and corresponds to the position of the supporting boss 1110; the tooth screw 410 is arranged at the end of the pressure-bearing pull rod 3210; the screw rod of the tooth screw 410 penetrates the pressure-bearing pull rod 3210 and the supporting boss 1110 in sequence and is threadedly connected to the fastening nut 420 to lock and fix the pressure-bearing pull rod 3210 and the shell 100. It can be understood that, since the fastening nut 420 arranged on the inner side of the shell 100 corresponds to the position of the supporting boss 1110, and the tooth screw 410 is arranged at the end of the pressure-bearing pull rod 3210, the screw rod of the tooth screw 410 can penetrate the pressure-bearing pull rod 3210 and the supporting boss 1110 in sequence and be threadedly connected to the fastening nut 420, so that the pressure-bearing pull rod 3210 and the shell 100 can be locked and fixed by screwing the tooth screw 410. In this way, compared with the traditional self-tapping screw, the tooth screw 410 and the fastening nut 420 are more resistant to the weight of the shell 100 and are less likely to crack and fail to connect.

[0045] Please refer to Figure 2In some embodiments, the pulling assembly 300 further comprises a hand protection sleeve 330 sleeved outside the soft pulling band 310. It can be understood that, since the hand protection sleeve 330 is sleeved outside the soft pulling band 310, the contact force during the pulling process by the hand can be increased through the hand protection sleeve 330, so as to reduce the local pressure of the hand and improve the comfort of pulling. Specifically, the hand protection sleeve 330 is a silica gel sleeve.

[0046] Please refer to Figure 1 and Figure 2 It can be understood that, by applying the battery pulling structure of the present disclosure in the battery pack, since the two ends of the pulling assembly 300 are fixedly connected to the shell 100, and the movable pulling handle of the pulling assembly 300 is movably accommodated in the limiting groove 201 formed between the two limiting fences 200, the movable pulling handle can be accommodated in the limiting groove 201, so as to constrain the movable pulling handle at the taking and placing position, thereby reducing the random swinging of the movable pulling handle. Since the two limiting fences 200 are located on the flat palm stretching area 101, the through-finger notch 202 on each limiting fence 200 is communicated with the limiting groove 201 and corresponds to the position of one side of the movable pulling handle, respectively, and the flat palm stretching area 101 can provide more space for the hand, so that each finger can be more easily inserted into each through-finger notch 202, so that the two sides of the movable pulling handle can be quickly gripped and pulled up by the fingers, thereby improving the convenience of gripping the pulling assembly 300 by the hand.

[0047] Compared with the prior art, the present disclosure has at least the following advantages:

[0048] The battery pulling structure described above, since the two ends of the pulling assembly 300 are fixedly connected to the shell 100, and the movable pulling handle of the pulling assembly 300 is movably accommodated in the limiting groove 201 formed between the two limiting fences 200, the movable pulling handle can be accommodated in the limiting groove 201, so as to constrain the movable pulling handle at the taking and placing position, thereby reducing the random swinging of the movable pulling handle. Since the two limiting fences 200 are located on the flat palm stretching area 101, the through-finger notch 202 on each limiting fence 200 is communicated with the limiting groove 201 and corresponds to the position of one side of the movable pulling handle, respectively, and the flat palm stretching area 101 can provide more space for the hand, so that each finger can be more easily inserted into each through-finger notch 202, so that the two sides of the movable pulling handle can be quickly gripped and pulled up by the fingers, thereby improving the convenience of gripping the pulling assembly 300 by the hand.

[0049] The above-described embodiments only express several implementation manners of the present disclosure, which are described in a more specific and detailed manner, but cannot be understood as a limitation on the scope of the utility model patent. It should be noted that, for ordinary skilled persons in the art, several modifications and improvements can be made without departing from the concept of the present disclosure, which all belong to the protection scope of the present disclosure.
