A locking structure 100 for a battery pack 300 according to an embodiment of the present invention is described below with reference to fig. 1 to 9.
As shown in fig. 1 to 7, a locking structure 100 for a battery pack 300 according to an embodiment of the present invention includes: the mounting fastener 110 and the second limiting piece 140, the mounting fastener 110 is suitable for penetrating through the battery pack 300 to be fixed with the vehicle body, and the first limiting piece 120 is arranged on the mounting fastener 110; the second limiting member 140 is sleeved on the mounting fastener 110 and can slide up and down relative to the mounting fastener 110, and the battery pack 300 is provided with an anti-rotation member 130 for limiting the rotation of the second limiting member 140; the second limiting member 140 has a locking position and an unlocking position, when the second limiting member 140 is located at the locking position, the second limiting member 140 is matched with the first limiting member 120 to limit the rotation of the mounting fastener 110, and when the second limiting member 140 is located at the unlocking position, the second limiting member 140 is separated from the first limiting member 120.
specifically, the mounting fastener 110 is adapted to cooperate with a nut 400 on the vehicle body to fix the battery pack 300 on the vehicle body, and after the mounting fastener 110 is fastened and engaged with the nut 400 on the vehicle body, the second limiting member 140 locks the first limiting member 120, so as to achieve the effect of locking the mounting fastener 110, and when the battery pack 300 needs to be replaced, the first limiting member 120 is separated from the second limiting member 140, so that the battery pack 300 can be detached.
It can be understood that the second limiting member 140 is matched with the rotation-preventing member 130, so that the second limiting member 140 cannot rotate relative to the battery pack 300, and further, the locking of the mounting fastener 110 can be realized by matching the second limiting member 140 which cannot rotate with the first limiting member 120 which is sleeved on the mounting fastener 110, and after the second limiting member 140 slides upwards away from the first limiting member 120, the second limiting member 140 is at the unlocking position, and after the second limiting member 140 slides towards the first limiting member 120 and is matched with the first limiting member 120, the second limiting member 140 is at the locking position.
According to the utility model discloses a locking structure 100 for battery package 300, through setting up first locating part 120 and second locating part 140, and make second locating part 140 slide from top to bottom, in order to realize the switching of second locating part 140 between unblock position and locking position, not only make locking structure 100's structure simpler, the locking effect is better, the reliability is higher, and first locating part 120 is simpler with second locating part 140's locking, in-process changing battery package 300, wearing and tearing to installation fastener 110 are less, can prolong installation fastener 110's life.
as shown in fig. 1, 3, 5, and 7, the first limiting member 120 includes: the first base 121 and the first limiting tooth 122 are arranged on the mounting fastener 110 in a sleeved mode; the first limit teeth 122 are multiple, and the multiple first limit teeth 122 are circumferentially arranged on the upper surface of the first base 121 at intervals; the second limiting member 140 includes: the mounting structure comprises a second base 141 and a first limiting tooth groove 142, wherein the second base 141 is sleeved on the mounting fastener 110; the first limit tooth grooves 142 are formed in a plurality of numbers, the first limit tooth grooves 142 are circumferentially arranged on the lower surface of the second base 141 at intervals, and each first limit tooth groove 142 is suitable for being matched with the corresponding first limit tooth 122.
That is to say, the circumferential edge of the upper surface of the first base 121 facing the second base 141 is provided with a plurality of first limit teeth 122 extending toward the second base 141, a tooth space is formed between adjacent first limit teeth 122, the circumferential edge of the lower surface of the corresponding second base 141 facing the first base 121 is provided with a plurality of teeth corresponding to the tooth space between the adjacent first limit teeth 122, a first limit tooth space 142 is formed between the adjacent teeth corresponding to the tooth space between the first limit teeth 122, and the first limit teeth 122 are matched with the corresponding first limit tooth space 142.
As shown in fig. 7, the slope of the tooth side of the first stopper tooth 122 that coincides with the rotation direction of the mounting fastener 110 when it is tightened is small, and the slope of the tooth side of the first stopper tooth 122 that coincides with the rotation direction of the mounting fastener 110 when it is loosened is large.
In this way, by providing the first limiting tooth 122 and the first limiting tooth slot 142, the locking effect of the first limiting member 120 and the second limiting member 140 is better, and the locking cooperation between the first limiting member 120 and the second limiting member 140 is more stable and reliable.
In the specific embodiment shown in fig. 1 and 7, the mounting fastener 110 further has a guide portion 111, and the guide portion 111 is adapted to guide when the mounting fastener 110 passes through the battery pack 300 to be coupled with the nut 400 of the vehicle body hill-change, so that the assembly efficiency can be further improved.
