Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0044] Example 1:

[0045] like Figure 1 As shown, the vehicle includes a frame 10 and a battery box 20, wherein the battery box 20 is fixedly mounted on the frame 10.

[0046] In this embodiment, the direction is defined by a three-axis spatial coordinate system, where the X-axis is the first direction, the Y-axis is the second direction, and the Z-axis is the third direction. Specifically, in this embodiment, the length direction of the frame 10 is the third direction, the width direction of the frame 10 is the first direction (which can also be understood as the width direction of the car), and the second direction is the height direction of the car.

[0047] Specifically, the connecting piece 1 is fixedly installed on the frame 10, wherein the connecting piece 1 is arranged on the side wall of the frame 10 and extends along the first direction X, and it is worth noting that the cross section C of the connecting piece 1 is shaped, the connecting piece 1 is provided with a connecting groove 11 which is open on one side, the automobile comprises two pairs of opposite frames 10, wherein the openings of the connecting pieces 1 on the two frames 10 are aligned with each other, and the side wall of the battery box 20 is fixedly provided with a connecting block 2, and when the battery box 20 is installed, the connecting block 2 is inserted into the connecting groove 11 of the connecting piece 1.

[0048] In order to limit the sliding of the battery box 20 along the first direction X, in the embodiment, as shown in Figure 1 , a limiting groove 111 and a limiting plate 4 are further included, wherein the limiting groove 111 is arranged on the top of the connecting piece 1 and extends downward along the second direction Y, so that the limiting groove 111 is in communication with the connecting groove 11, and specifically, the connecting block 2 is further provided with an insertion groove, and the limiting plate 4 is inserted into the insertion groove of the connecting block 2 through the limiting groove 111, and the abutment between the outer wall of the limiting plate 4 and the inner wall of the insertion groove limits the movement of the connecting block 2 along the first direction X, thereby achieving the fixation of the battery box 20 and the frame 10.

[0049] Alternatively, the outer wall of the connecting block 2 is provided with a clamping surface, and when the limiting plate 4 is inserted into the connecting groove 11 from the limiting groove 111, the side wall of the limiting plate 4 abuts against the clamping surface of the connecting block 2, thereby limiting the movement of the connecting block 2 along the first direction X.

[0050] In order to improve the fixing effect of the limiting plate 4 on the connecting block 2, in the embodiment, as shown in Figure 1 , a resilient member 3 is further included, wherein the resilient member 3 is installed in the connecting groove 11, when the battery box 20 is installed, the connecting block 2 is inserted into the connecting groove 11 along the first direction X, so that the end wall of the connecting block 2 abuts against the resilient member 3, thereby causing the resilient member 3 to deform, and then the limiting plate 4 is inserted into the limiting groove 111; the resilient member 3 provides a pushing force to the connecting block 2 to make the connecting block 2 tend to move out of the connecting groove 11 along the first direction X, at this time, the connecting block 2 pushes the limiting plate 4 to move and abut against the inner wall of the limiting groove 111, thereby strengthening the firmness of the connecting block 2 and reducing the risk of the limiting plate 4 falling off the connecting piece 1 due to vibration of the vehicle.

[0051] It is worth noting further that the resilient member 3 is made of rubber material, and the use of the resilient member 3 can reduce the influence of vehicle vibration on the battery box 20 and prolong the service life of the battery box 20.

[0052] Embodiment two:

[0053] In the embodiment, please refer to Figures 2-10 .

[0054] As shown in Figure 2As shown, the vehicle includes a frame 10 and a battery box 20, specifically, the frame 10 is provided with two frames 10 arranged oppositely, and the battery box 20 is installed between the two frames 10, and then the battery box 20 is fixed on the frame 10.

[0055] For the convenience of description, in the embodiment, the direction is redefined, specifically, a three-axis space coordinate system is established, including a first direction X, a second direction Y and a third direction Z, wherein the length direction of the frame 10, which can also be said to be the length direction of the vehicle, is the third direction Z, the height direction of the vehicle is the first direction X, which can also be expressed as up and down, and the width direction of the vehicle is the second direction Y, specifically, the connecting piece 1 arranged along the second direction Y is fixed on the frame 10, such as Figure 2 and Figure 3 As shown, the connecting piece 1 is provided with a connecting groove 11, specifically, the cross section of the connecting piece 1 is C-shaped with the opening downward, and the connecting block 2 is fixed on the battery box 20, and the connecting block 2 on the battery box 20 can be inserted into the connecting groove 11 along the first direction X, when the connecting block 2 is inserted into the connecting groove 11, since the connecting groove 11 is arranged with the opening downward, in order to avoid the connecting block 2 from falling off from the connecting groove 11 along the first direction X, in the embodiment, as shown in Figure 4 and Figure 5 It further includes a limiting plate 4 for packaging the connecting block 2 in the connecting groove 11 to limit the movement of the connecting block 2 along the first direction X.

[0056] In order to realize the installation of the limiting plate 4 and solve the movement of the connecting block 2 along the first direction X, as shown in Figure 5 The inner wall of the connecting groove 11 is further provided with a clamping port 122, and the limiting plate 4 is inserted into the clamping port 122, and the limiting plate 4 is abutted with the connecting block 2, thereby solving the problem of the connecting block 2 falling off from the connecting groove 11 along the first direction X.

[0057] The installation process of the battery box 20 of the vehicle is as follows, the vehicle is lifted upward to expose the chassis of the vehicle, the battery box 20 is lifted upward, so that the connecting block 2 is inserted into the connecting groove 11 of the connecting piece 1 along the first direction X, and then the limiting plate 4 is clamped in the clamping port 122, the clamping port 122 limits the movement of the limiting plate 4 along the first direction X, at this time, the limiting plate 4 is abutted with the bottom wall of the connecting block 2, thereby realizing the fixation of the connecting block 2, wherein the battery box 20 is supported by the limiting plate 4 to maintain the stability of the battery box 20.

[0058] Since the distance between the two frames 10 of the vehicle is certain, when the connecting block 2 of the battery box 20 is inserted into the connecting groove 11, the battery box 20 has the risk of moving along the second direction Y, in order to solve this problem, in the embodiment, as shown in Figure 7 and Figure 8As shown in the figure, the inner wall of the connecting groove 11 is fixedly provided with a plurality of positioning plates 12 extending along the first direction X, wherein the positioning groove 121 is formed between the adjacent two positioning plates 12 and the side wall of the connecting groove 11, and the side wall of the connecting block 2 is fixedly provided with a positioning block 21, when the battery box 20 is installed, the positioning block 21 is inserted into the positioning groove 121 along the first direction X, at this time, the side wall of the positioning block 21 abuts against the inner wall of the positioning groove 121, so as to limit the movement of the connecting block 2 along the second direction Y.

[0059] Specifically, in the embodiment, as shown in the figure, Figure 7 The clamping interface 122 is arranged on the positioning plate 12.

[0060] In order to clamp the limiting plate 4 in the clamping interface 122 to fix the connecting block 2, in the embodiment, the limiting plate 4 is rectangular, when the connecting block 2 and the positioning block 21 are respectively inserted into the connecting groove 11 and the positioning groove 121, the limiting plate 4 is put into the connecting groove 11 along the first direction X and abuts against the connecting block 2, then the limiting plate 4 is rotated by ninety degrees, at this time, the limiting plate 4 is screwed into the clamping interface 122, so as to realize the fixation of the limiting plate 4, and the limiting plate 4 and the positioning plate 12 are used to support the battery box 20.

[0061] It is worth mentioning here that the positioning plate 12 and the connecting piece 1 are welded.

[0062] In order to facilitate the rotation of the limiting plate 4, in the embodiment, as shown in the figure, Figure 6 And Figure 10 The rotating pipe 41 extending along the first direction X is fixedly arranged on the limiting plate 4, wherein the bottom end of the rotating pipe 41 extends out of the connecting groove 11, and the angle of the limiting plate 4 can be adjusted through the rotating pipe 41.

[0063] In order to improve the accuracy of the insertion of the limiting plate 4 into the connecting groove 11, in the embodiment, as shown in the figure, Figure 4 And Figure 8 The positioning rod 22 arranged along the first direction X is fixedly arranged on the connecting block 2, when the limiting plate 4 is installed, the positioning rod 22 is inserted into the rotating pipe 41, so as to realize the positioning of the position of the limiting plate 4 and improve the accuracy of the installation of the limiting plate 4.

[0064] It is worth mentioning here that, since the connecting block 2 is inserted into the positioning groove 121 through the positioning block 21 to limit the movement of the connecting block 2 along the second direction Y, when the rotating pipe 41 on the limiting plate 4 is sleeved on the positioning rod 22, the positioning rod 22 can limit the movement of the limiting plate 4 along the second direction Y, so that the limiting plate 4 can only rotate around the axis of the positioning rod 22, and when the limiting plate 4 is clamped in the clamping interface 122, the movement of the limiting plate 4 along the first direction X is also limited.

[0065] In the embodiment, the weight of the battery box 20 is supported by the limiting plate 4 and the positioning plate 12. When the positioning plate 12 is separated from the connecting piece 1, the battery box 20 has the risk of falling off the frame 10. In order to reduce the risk of the battery box 20 falling off, in the embodiment, as shown in Figure 2 、 Figure 3 and Figure 6 indicate that the sliding sleeve 5 is further included for switching between the first state and the second state, wherein the sliding sleeve 5 is sleeved on the outer side of the connecting piece 1, the connecting piece 1 is slidingly connected with the sliding sleeve 5 along the first direction X, in the first state, the sliding sleeve 5 exposes the positioning groove 121 on the connecting piece 1, so that the positioning block 21 on the connecting block 2 is inserted into the positioning groove 121 along the first direction X, when the connecting block 2 is installed, the sliding sleeve 5 slides to the second state, as shown in Figure 6 , at this time, the sliding sleeve 5 blocks the positioning groove 121, and the bottom end wall of the positioning plate 12 abuts against the inner wall of the sliding sleeve 5. Even if the positioning plate 12 is damaged due to fatigue strength, the sliding sleeve 5 can support the gravity of the battery box 20, thereby reducing the risk of the battery box 20 falling off the frame 10.

[0066] Since the rotating pipe 41 on the limiting plate 4 extends downward through the connecting groove 11, in order to avoid that the rotating pipe 41 limits the movement of the sliding sleeve 5, in the embodiment, as shown in Figure 6 and Figure 9 , the sliding sleeve 5 is further provided with an avoiding opening 51, when the sliding sleeve 5 is in the second state, the rotating pipe 41 is located in the avoiding opening 51.

[0067] In order to realize the automatic movement of the sliding sleeve 5, in the embodiment, as shown in Figure 2 and Figure 3 , a spring 6 is further included for sleeving on the connecting piece 1, wherein one end of the spring 6 is fixedly connected with the sliding sleeve 5, and the other end of the spring 6 is fixedly connected with the connecting piece 1. In the second state, the spring 6 is in the original length state, and in the first state, the spring 6 is in the compressed state.

[0068] If the limiting plate 4 is not clamped into the clamping opening 122 or the limiting plate 4 is separated from the clamping opening 122 due to vibration of the vehicle, at this time, the limiting plate 4 cannot support the connecting block 2, and at this time, the battery box 20 still has the risk of falling off the frame 10. Therefore, in the embodiment, a supporting plate 42 is further fixed on the outer wall of the rotating pipe 41, when the sliding sleeve 5 is in the second state, the bottom wall of the supporting plate 42 abuts against the inner wall of the sliding sleeve 5. Even if the limiting plate 4 is separated from the clamping opening 122, at this time, the connecting block 2 can transmit the gravity to the sliding sleeve 5 through the limiting plate 4, the rotating pipe 41 and the supporting plate 42, so as to lift the battery box 20 by the sliding sleeve 5, thereby reducing the risk of the battery box 20 falling off the frame 10.

[0069] To further enable the rotation of the rotating tube 41, the end of the rotating tube 41 is hexagonal so that the adjustable wrench can engage.

[0070] In this embodiment, as Figure 6 As shown, when the battery box 20 is installed, in order to reduce the risk of the limiting plate 4 coming off the card interface 122, an elastic element 3 is also included. The elastic element 3 is located between the top wall of the connecting block 2 and the inner wall of the connecting groove 11. The elastic element 3 applies a downward pushing force to the limiting plate 4 through the connecting block 2, so that the limiting plate 4 abuts against the card interface 122, reducing the risk of the limiting plate 4 rotating.

[0071] In this embodiment, it is worth noting that the advantage of setting the opening of the connecting groove 11 downward is that it is convenient to install the battery box 20 from the bottom of the car onto the frame 10, and to facilitate the overall replacement of the battery box 20.

[0072] When replacing the battery box 20, switch the sliding sleeve 5 from the second state to the first state, then support the battery box 20 upwards to reduce the pressure of the battery box 20 on the limiting plate 4. Then rotate the limiting plate 4 through the rotating tube 41 to disengage the limiting plate 4 from the card interface 122. Remove the limiting plate 4, and the battery box 20 will be placed downwards under its own weight, thereby moving the connecting block 2 out of the connecting groove 11 and removing the battery box 20. Then, follow the reverse steps to install the new battery box 20.
