Fig. 14 is an enlarged view of the first end of the quick-change frame of the present invention. Fig. 15 is an enlarged view of the second end of the quick-change frame of the present invention. As shown in fig. 1 to 15, the vehicle-mounted power battery assembly 10 of the invention includes: a vehicle-mounted power battery 1 and a quick-change frame 2. The quick-change frame 2 comprises a first set of opposite sides and a second set of opposite sides. The inner sides of the first group of opposite sides of the quick-change frame 2 are provided with a first locking component 201, a second locking component 202 and a supporting hanging point 203. The first locking assembly 201 comprises a locking member 207 and at least one limiting member 205 matched with the locking member 207 to limit and connect the vehicle-mounted power battery 1. The second locking assembly 202 includes at least one limiting member 205 to connect with the vehicle-mounted power battery 1. The support hanging point 203 is used for providing support for the vehicle-mounted power battery 1.
Specifically, the first locking assembly 201 functions to precisely lock (cooperate with) the vehicle-mounted power battery 1 to the quick-change frame 2. When the first locking component 201 includes a plurality of limiting members 205, the plurality of limiting members 205 can further limit the vehicle-mounted power battery 1 in the first set of opposite extending directions through the connecting member 204. The second locking assembly 202 is used for coarse locking, i.e., connecting the vehicle power battery 1, but the vehicle power battery 1 can move within a very small clearance range. The second locking assembly 202 operates only when the first locking assembly 201 fails, and the second locking assembly 202 is used to ensure that the vehicle-mounted power battery 1 does not fall off the quick-change frame 2. The support hanging point 203 is used only for support in consideration of the weight of the vehicle-mounted power battery 1 and the rigidity requirement when the vehicle-mounted power battery 1 is mounted. Therefore, the vehicle-mounted power battery assembly of the invention firmly installs the vehicle-mounted power battery on the quick-change frame through the first locking assembly 201, the second locking assembly 202 and the supporting hanging point 203, and can prevent the vehicle-mounted power battery from firmly moving in the quick-change frame during the running of the vehicle, reduce abnormal sound caused by friction during the running of the vehicle, reduce maintenance cost and improve driving comfort.
Specifically, the number and the position matching of the first locking assembly 201, the second locking assembly 202 and the support hanging points 203 can be adjusted according to the weight of the vehicle-mounted power battery 1. According to the invention, the limit of the vehicle-mounted power battery 1 can be ensured and the vehicle-mounted power battery 1 can be prevented from falling from the quick-change frame 2 through double locking. The invention also disperses the stress of the vehicle-mounted power battery 1 through the distributed multiple supporting hanging points 203, thereby facilitating the installation and the stability of the vehicle-mounted power battery 1 in the quick-change frame 2. In a preferred embodiment, the first pair of opposite sides of the quick-change frame 2 respectively comprises a first locking member 201, a second locking member 202 and four supporting hanging points 203. The first locking element 201 includes three position limiters 205. The second locking assembly 202 includes a retaining member 205. The limiting members 205 of the first locking assembly 201 and the second locking assembly 202 can also support the vehicle-mounted power battery 1. The above embodiments are merely exemplary, and the present invention is not limited thereto.
In a specific embodiment of the present invention, the outer side edge of the vehicle-mounted power battery 1 has a locking part, which may be, for example, a locking shaft 40, and the support, the locking and the limiting of the vehicle-mounted power battery 1 are realized by the cooperation of the locking shaft 40 with the first locking component 201, the second locking component 202 and the support hanging point 203. Specifically, the first locking assembly 201, the second locking assembly 202 and the support hanging point 203 each include a limiting member 205 having a limiting groove. The first locking assembly 201 includes a limiting member 205 and a locking member 207 cooperating with the limiting member 205, the locking member 207 can rotate in the direction of the dotted arrow shown in fig. 5 to enable the lock shaft 40 to enter the limiting groove of the limiting member 205, and when the lock shaft 40 enters the limiting groove of the limiting member 205, the locking member 207 returns to the position shown in fig. 5 to limit the lock shaft 40 between the locking member 207 and the inner wall of the limiting groove (as shown in fig. 7). The second locking assembly 202 includes a limiting member 205 and a locking member 215 engaged with the limiting member 205. The locking member 215 may be a locking member 215 that is rotated and locked by a spring, and the lock shaft 40 is defined between the locking member 215 and an inner wall of the limiting recess by the locking member 215 and the limiting member 205, similar to the first locking member 201. Further, the spacing space between the locking member 215 and the inner wall of the spacing groove is larger than the spacing space between the locking member 207 and the inner wall of the spacing groove, so that the first locking member 201 achieves accurate spacing, the second locking member 202 achieves coarse spacing, and the spacing effect of the second locking member 202 only acts when the first locking member 201 fails. The support hanging point 203 may comprise only a limit stop 205 to provide support to the vehicle power battery 1 by providing support to the lock shaft 40 within the limit recess. The above description is only for schematically describing the embodiment of the present invention, and the present invention is not limited thereto, and other structures of the second locking assembly 202 and the supporting hanging point 203 are also within the protection scope of the present invention.

In one specific implementation, the reinforcing bracket 28 is arranged corresponding to the second screw hole 22, and the strength of the fixing point of the external expansion screw joint plate 26 and the chassis of the vehicle body is improved in a targeted manner. In one implementation, adjacent reinforcing brackets 28 have a symmetrical configuration to reduce product variety and facilitate manufacturing. In a specific implementation, the reinforcing brackets 28 are contoured to avoid screw holes and other features on both mounting surfaces to reduce interference with each other.
In a preferred embodiment, one of the second pair of opposite sides of the quick-change frame 2 is provided with an electrical connector 24, the first pair of opposite sides has a first end close to the electrical connector 24 and a second end facing away from the electrical connector 24, and at the second end of the first pair of opposite sides, a reinforcing bracket 28 is provided between the flange 206 and the first pair of opposite sides of the quick-change frame 2.

The reinforcing sleeve 25 is used for reinforcing the rigidity of the third screw hole 21 and avoiding deformation of the third screw hole 21 caused by bolt tightening due to no support in the cavity. In one specific implementation, the reinforcing bracket 28 is disposed corresponding to the third screw hole 21, and the strength of the fixing point of the flange 206 to the chassis is increased in a targeted manner.
In a preferred embodiment, at least two external expanding shoulders 27 for connecting the vehicle body are respectively arranged on the outer sides of the second group of opposite sides, and the external expanding shoulders 27 are provided with first screw holes 23.
