As shown in fig. 1 to 4, the quick-change mounting structure of the power battery includes: a vehicle body side mounting portion 100 for connection with a vehicle body, a battery side mounting portion 200 for connection with a power battery, a fastener 300, and a nut 400. The vehicle body-side mounting portion 100 is provided with a first via hole 103. The battery-side mounting portion 200 is provided with a second via hole 204.
The fastener 300 is provided with a head 300a and a connecting portion 300b in this order in the axial direction, and the connecting portion 300b is provided with a thread on the outer periphery. The connection portion 300b is screwed to the nut 400 after passing through the first and second through holes 103 and 204 in sequence.
The connecting portion 300b of the fastener 300 is in limited connection with the battery-side mounting portion 200 in the axial direction of the fastener 300 to prevent the fastener 300 from being separated from the battery-side mounting portion 200 when the fastener 300 moves in the axial direction.
The fastener 300 is axially rotatable about itself such that when rotated to a first angular position (solid line position in fig. 3), the head 300a of the fastener 300 cannot pass through the first aperture 103, and when rotated to a second angular position (dashed line position in fig. 3), the head 300a of the fastener 300 can pass through the first aperture 103.
In the illustrated embodiment, the head 300a of the fastener 300 has a bar-shaped configuration, and the first via 103 is a straight-line-shaped hole. Of course, the present invention is not limited thereto, as long as it is ensured that the head 300a cannot pass through the first through hole 103 when rotated to the first angular position, and the head 300a can pass through the first through hole 103 when rotated to the second angular position.
In the illustrated orientation, the first through hole 103 is located above the second through hole 204, the axial direction of the fastener 300 is the vertical direction, and the lower end of the connecting portion 300b is screwed to the nut 400. For ease of understanding, the mounting structure will be described below with reference to the orientation shown as an example. It should be noted that the illustrated orientations are exemplary only and do not represent orientations that may be configured in the illustrated orientation for the mounting structure application.
With this mounting structure, when the power battery is to be removed, the nut 400 is unscrewed, the fastener 300 is then rotated to the second angular position, and the battery-side mounting portion 200 connected to the power battery is then moved downward, and since the connecting portion 300b of the fastener 300 is connected to the battery-side mounting portion 200 in the axial direction of the fastener 300, the fastener 300 can be driven to move downward when the battery-side mounting portion 200 is moved downward, so that the head portion 300a of the fastener 300 passes through the first through hole 103 of the vehicle-side mounting portion 100 and is separated from the vehicle-side mounting portion 100, and thus the power battery can be removed together with the fastener 300 and the battery-side mounting portion 200.
When the power battery is mounted, the battery-side mounting portion 200 and the power battery connected thereto and the fastener 300 are placed under the vehicle body, then the fastener 300 is sequentially passed through the second through hole 204 and the first through hole 103 from bottom to top until the head 300a of the fastener 300 is positioned above the first through hole 103, then the fastener 300 is rotated to the first angular position and is held at the first angular position, and then the nut 400 is tightened, so that the battery-side mounting portion 200 and the power battery connected thereto can be mounted on the vehicle-body-side mounting portion 100.
It can be known from the above description that, with this mounting structure, only need to unscrew behind the nut 400 with fastener 300 rotation to the second angular position, just can dismantle power battery from the automobile body installation department, only need screw nut 400 after rotating fastener 300 to first angular position, just can make power battery install on the automobile body installation department firmly, the dismouting operation is very simple, labour saving and time saving, the dismouting change efficiency that makes power battery can promote.

Through setting up first spacing arch 102a and the spacing arch 102b of second, at the in-process of installation power battery, fastener 300 can keep at first angular position under the limiting displacement of first spacing arch 102a and the spacing arch 102b of second, and need not artificially exert the spacing power to fastener 300 manually, consequently can further simplify the installation operation, moreover, can ensure that installation completion back fastener 300 is difficult to rotatory not hard up, promote fastness and reliability.
With the first and second limiting protrusions 102a and 102b, the fastener 300 can be rotated to the second angular position only when the head 300a of the fastener 300 is located above the first and second limiting protrusions 102a and 102b during the process of disassembling the power battery.
Specifically, the vehicle-body side mounting portion 100 includes a vehicle-body side mounting plate 101 and a transition plate 102. The vehicle body side mounting plate 101 is fixedly connected to or integrally provided with the vehicle body. The transition plate 102 is mounted to the vehicle-body side mounting plate 101. The first via hole 103 is provided through the transition plate 102 and the vehicle body-side mounting plate 101. The first limit protrusion 102a and the second limit protrusion 102b are provided at the transition plate 102. The first through hole 103 is provided to penetrate the transition plate 102 and the vehicle body-side mounting plate 101, so that the strength at the first through hole 103 is high. The first limiting protrusion 102a and the second limiting protrusion 102b are disposed on the transition plate 102, and the transition plate 102 can be separately processed and manufactured, so as to form the first limiting protrusion 102a and the second limiting protrusion 102b. In actual practice, of course, the transition plate 102 may not be provided if the strength of the first through hole 103 is sufficient and the first stopper projection 102a and the second stopper projection 102b are easily formed together with the vehicle body side mounting plate 101.
In the illustrated embodiment, the vehicle-body-side mounting plate 101 is a plate-like structure having three flat plates, two of which are substantially parallel to the axial direction of the fastener 300, and the other flat plate is attached between the two flat plates and substantially perpendicular to the axial direction of the fastener 300. Of course, the structure of the vehicle-body-side mounting plate 101 is not limited to the illustrated embodiment, and the design can be flexibly made according to the shape of the corresponding position of the vehicle body, and the shape of the vehicle-body-side mounting plate 101 is not limited in the present application.
Specifically, as described above, the connecting portion 300b of the fastener 300 is connected to the battery-side mounting portion 200 in a limited manner in the axial direction of the fastener 300, so that the fastener 300 is prevented from being separated from the battery-side mounting portion 200 when moving in the axial direction, and the fastener 300 and the battery-side mounting portion 200 are always connected together in the mounting and dismounting process. The connecting portion 300b of the fastener 300 and the battery-side mounting portion 200 are connected to each other in the axial direction of the fastener 300 in various manners. For example, in the illustrated embodiment, the protrusion 300c is disposed on the outer circumferential wall surface of the connecting portion 300b of the fastener 300, the circumferential groove is disposed on the inner circumferential wall surface of the second through hole 204, the positions of the protrusion 300c and the circumferential groove may be reversed, when the fastener 300 is inserted into the second through hole 204, the protrusion 300c extends into the circumferential groove, and when the fastener 300 axially moves to the limit position, the protrusion 300c can abut against the sidewall of the circumferential groove, so that the limit connection between the fastener 300 and the battery-side mounting portion 200 in the axial direction of the fastener 300 is realized. For another example, the two components may be connected in a limited manner in the axial direction of the fastener 300 by a snap fit or a spring connection with moderate elastic force.

When the limiting connection is realized by adopting the protrusion 300c and the circumferential groove, in order to ensure that the fastener 300 can be smoothly inserted into the second through hole 204 during assembly, the protrusion 300c can be set to be an elastic telescopic structure, the protrusion 300c retracts under the interference action of the inner peripheral wall surface of the second through hole 204 during assembly, and when the fastener 300 is installed at the position where the protrusion 300c is opposite to the circumferential groove, the protrusion 300c extends into the circumferential groove; alternatively, an axial groove may be formed in the circumferential wall surface on which the circumferential groove is formed, one end of the axial groove is made to penetrate through the circumferential groove, a through hole is formed at the through position, the boss 300c is slidably mounted in the circumferential groove along the axial groove from the other end of the axial groove, and then the fastener 300 is rotated to make the boss 300c and the through hole circumferentially staggered from each other.
Specifically, the battery-side mounting portion 200 may include a battery-side mounting plate 201 and a mounting sleeve 202. The battery side mounting plate 201 is fixedly connected with or integrally arranged with the power battery. The mounting sleeve 202 is mounted to the battery-side mounting plate 201, and the second through hole 204 is an inner hole of the mounting sleeve 202. Of course, in actual practice, the second through hole 204 may be provided directly on the battery-side mounting plate 201 without providing the mounting sleeve 202. In contrast, the installation sleeve 202 is provided to utilize the inner bore of the installation sleeve 202 as the second through hole 204, so that the strength at the second through hole 204 is high, and the installation sleeve 202 can provide an installation basis for the seal (the assembly relationship between the seal and the installation sleeve 202 will be further described later).
In the illustrated embodiment, the battery side mounting plate 201 has a flat plate substantially parallel to the axial direction of the fastener 300 and a plate-shaped material having a trapezoidal cross section, and the open side of the plate-shaped material is connected to the flat plate and is a large-area side, and the battery side mounting plate 201 has high structural strength. Of course, the structure of the battery side mounting plate 201 is not limited to the illustrated embodiment, and the design may be flexible according to the shape of the corresponding position of the power battery, and the shape of the battery side mounting plate 201 is not limited in the present application.
Specifically, the connection mode of the battery side mounting plate 201 and the mounting sleeve 202 is various, and it is sufficient if the mounting sleeve 202 can be stably fixed to the battery side mounting plate 201. For example, in the illustrated embodiment, the battery side mounting plate 201 is provided with the mounting hole 201a and the connection hole 201b, in the figure, the connection hole 201b is provided on the plate surface of the plate-shaped material substantially perpendicular to the axial direction of the fastener 300, the mounting sleeve 202 has the sleeve body 202a and the lug plate 202b provided on the outer periphery of the sleeve body 202a, the sleeve body 202a is inserted into the mounting hole 201a, and the lug plate 202b is supported on the vehicle body side mounting plate 101 and is connected to the connection hole 201b by the threaded fastener 203.
Further, as shown in fig. 3, the quick-change mounting structure may further include a sealing member, which includes an inner sealing ring 500 and an outer sealing ring 600.
The inner seal ring 500 is mounted in the inner bore of the mounting sleeve 202 at one end of the inner bore close to the body-side mounting plate 101, and the inner seal ring 500 may be circumferentially positioned by a positioning structure. Nut 400 is mounted in the inner bore of mounting sleeve 202 at the end of the inner bore remote from body-side mounting plate 101.
