DETAILED DESCRIPTION

[0028] like Figures 1 to 6As shown, the utility model provides a heavy-duty battery-swap battery frame bottom bracket assembly, which is used to cooperate with the battery-swap battery frame upper frame 4. The heavy-duty battery-swap battery frame bottom bracket assembly includes: a bottom frame 1, the bottom frame 1 includes a main frame 101 arranged in a rectangular shape and a plurality of sub-frames 102 installed on the inner side of the main frame 101, the sub-frames 102 serve as the inner support structure of the main frame 101 to ensure the structural stability of the bottom frame 1, so that the positioning device can withstand greater impact and is not easily deformed, thereby improving durability; the top wall of the bottom frame 1 is installed with a buffer The gasket 103 is used to reduce the impact of the upper frame 4 of the battery swap frame on the bottom frame 1 when installing the upper frame 4 of the battery swap frame. A plurality of planar positioning mechanisms 2 and conical cylindrical positioning mechanisms 3 are installed on the bottom frame 1. The side walls of the planar positioning mechanisms 2 cooperate with the inner walls formed by the structural beams of the upper frame 4 of the battery swap frame. The conical cylindrical positioning mechanisms 3 cooperate with the positioning hole seats 401 installed on the upper frame 4 of the battery swap frame for positioning. A plurality of locking mechanisms 5 for limiting the vertical displacement of the upper frame 4 of the battery swap frame are installed on the bottom frame 1.

[0029] In the present scheme, the structural beam of the upper frame 4 of the battery swap frame forms a rectangular positioning space, and the planar positioning mechanism 2 is fitted with the inner wall of the rectangular positioning space to achieve rough positioning; the conical cylindrical positioning mechanism 3 is inserted into the positioning hole seat 401 to achieve fine positioning. The conical cylindrical positioning mechanism 3 includes a cylindrical positioning column and a conical positioning column arranged above the cylindrical positioning column. The conical positioning column is arranged to facilitate insertion into the positioning hole seat 401; the upper frame 4 of the battery swap frame is limited in the horizontal direction by the planar positioning mechanism 2 and the conical cylindrical positioning mechanism 3. After the upper frame 4 of the battery swap frame is installed on the bottom frame 1, the upper frame 4 of the battery swap frame is limited in the vertical direction by the locking mechanism 5. The locking mechanism 5 described in the present scheme is a technical feature well known to those skilled in the art, and the structural composition of the locking mechanism 5 will not be repeated here.

[0030] This solution ensures the convenience and stability of positioning by setting up multiple planar positioning mechanisms 2 and conical cylindrical positioning mechanisms 3, thereby improving the installation efficiency of the battery replacement system.

[0031] In one embodiment of the utility model, an elastic buffer sheet 201 is fixedly installed on the side wall of the plane positioning mechanism 2 that is in contact with the structural beam of the upper frame 4 of the battery exchange frame. The elastic buffer sheet 201 includes two plane sections 202 and an arc section 203 arranged between the two plane sections 202. One of the two plane sections 202 is fixedly installed on the plane positioning mechanism 2 by bolts to ensure the expansion and deformation ability of the elastic buffer sheet 201 when squeezed. The convex vertex of the arc section 203 is in contact with the inner wall of the structural beam of the upper frame 4 of the battery exchange frame. By setting the elastic buffer sheet 201, the lateral impact on the upper frame 4 of the battery exchange frame can be buffered.

[0032] In one embodiment of the utility model, the side wall of the planar positioning mechanism 2 is provided with a mounting groove 206, and the elastic buffer sheet 201 is installed in the mounting groove 206, wherein the plane section 202 is located in the mounting groove 206, and the arc section 203 can extend outside the mounting groove 206 to ensure the compactness of the structure and the flatness of the outer wall of the planar positioning mechanism 2.

[0033] In one embodiment of the utility model, a feedback sensor 6 is installed on the plane positioning mechanism 2, and the feedback sensor 6 is located inside the arc segment 203. Preferably, the feedback sensor 6 is a touch switch. When the upper frame 4 of the battery-swap battery frame is placed on the bottom bracket assembly of the heavy-duty battery-swap battery frame, the elastic buffer sheet 201 is squeezed, and further squeezing the feedback sensor 6 generates an electrical signal to be fed back to the battery-swap controller. The battery-swap controller can further control the battery-swap locking mechanism 5 to perform related actions according to the signal. On the contrary, when the upper frame 4 of the battery-swap battery frame is separated from the bottom bracket assembly of the heavy-duty battery-swap battery frame, the elastic buffer sheet 201 is reset, and the feedback sensor 6 feeds back a signal to the battery-swap controller.

[0034] In one embodiment of the utility model, the plane positioning mechanism 2 includes a double-plane positioning mechanism 204 and a single-plane positioning mechanism 205, and elastic buffer plates 201 are installed on the two perpendicular side walls of the double-plane positioning mechanism 204. The two vertical side walls of the double-plane positioning mechanism 204 are in contact with the inner wall at right angles to the structural beam of the upper frame 4 of the battery replacement battery frame, and the side wall plane on which the elastic buffer plate 201 is installed on the single-plane positioning mechanism 205 is in contact with the inner wall of the structural beam on the bottom frame 1 close to the single-plane positioning mechanism 205, and locking mechanisms are installed on the sides of the single-plane positioning mechanism 205.

[0035] In this scheme, the center of the bottom frame 1 is defined as the origin, the length direction of the bottom frame 1 is the X-axis, the width direction of the bottom frame 1 is the Y-axis, and the axial direction of the bottom frame 1 is the Z-axis. The plane positioning mechanisms 2 symmetrically arranged on both sides of the plane where the X-axis and the Z-axis are located are used to buffer the impact of the upper frame 4 of the battery replacement frame along the Y-axis direction, and the plane positioning mechanisms 2 symmetrically arranged on both sides of the plane where the Y-axis and the Z-axis are located are used to buffer the impact of the upper frame 4 of the battery replacement frame along the Z-axis direction. Among them, in the plane positioning mechanisms 2 symmetrically arranged on both sides of the plane where the X-axis and the Z-axis are located, one side of the plane positioning mechanism 2 includes a single plane positioning mechanism 205 located on the Y-axis and two double plane positioning mechanisms 204 symmetrically arranged about the Y-axis, so as to ensure the positioning and buffering capacity of the upper frame 4 of the battery replacement battery frame in the Y-axis direction; in the plane positioning mechanisms 2 symmetrically arranged on both sides of the plane where the Y-axis and the Z-axis are located, one side of the plane positioning mechanism 2 includes two single plane positioning mechanisms 205 symmetrically arranged about the plane where the X-axis and the Z-axis are located, so as to ensure the positioning and buffering capacity of the upper frame 4 of the battery replacement battery frame in the X-axis direction.

[0036] In one embodiment of the utility model, two groups of conical cylindrical positioning mechanisms 3 are provided on the bottom frame 1, and the two groups of conical cylindrical positioning mechanisms 3 are symmetrically arranged about the plane where the X-axis and Z-axis of the bottom frame 1 are located, and each group of conical cylindrical positioning mechanisms 3 includes two conical cylindrical positioning mechanisms 3 symmetrically arranged about the plane where the Y-axis and Z-axis of the bottom frame 1 are located.

[0037] In this solution, by setting up four conical cylindrical positioning mechanisms 3, the positioning accuracy of the upper frame 4 of the battery swapping frame is guaranteed, and the four conical cylindrical positioning mechanisms 3 are symmetrically arranged in pairs, which facilitates the positioning and installation of the upper frame 4 of the battery swapping frame.

[0039] A battery replacement system includes a heavy-duty battery replacement frame bottom support assembly and a battery replacement frame upper frame 4 that cooperates with the heavy-duty battery replacement frame bottom support assembly. The structural beam of the battery replacement frame upper frame 4 forms a positioning surface that cooperates with a planar positioning mechanism 2. The battery replacement frame upper frame 4 is provided with a plurality of positioning hole seats 401 that cooperate with a conical cylindrical positioning mechanism 3.

[0040] Finally, it should be noted that the above preferred embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail through the above preferred embodiments, those skilled in the art should understand that various changes can be made in form and details without departing from the scope defined by the claims of the utility model.
