DETAILED DESCRIPTION

[0029] The technical solutions in the application will be described clearly and completely below in combination with the drawings in the application. Obviously, the described embodiments are only part of the embodiments of the application, not all the embodiments. The description of the at least one example embodiment is actually only illustrative, not as any limitation on the application and its application or use. Embodiment one

[0030] The embodiment provides a mounting structure of a battery cabinet, to solve the problem that the mounting structure of the battery cabinet in the prior art is difficult to eliminate the shaking of the battery cabinet during vehicle driving, resulting in that the weight of the battery cabinet is limited.

[0031] Reference Figure 1 The mounting structure of the battery cabinet provided by the embodiment comprises,

[0032] The rotating shaft 4 is connected with the battery cabinet 1, and the rotating shaft 4 is used to be rotationally connected with a vehicle body. The shaking of the battery cabinet 1 with the vehicle body is relatively disordered, and the rotating shaft 4 is used to convert the shaking of the battery cabinet 1 into swinging around the rotating shaft 4 as the rotation center.

[0033] The damping assembly 6 is connected with the battery cabinet 1, and the damping assembly 6 is spaced apart from the rotating shaft 4 in position, so as to ensure that the reaction force of damping has a certain torque. The damping assembly 6 is used to be connected with the vehicle body, so as to slow down the vibration of the battery cabinet 1, i.e. slow down the swinging of the battery cabinet 1 around the rotating shaft 4.

[0034] In use, the battery cabinet 1 is rotationally connected with the side body of the vehicle body through the rotating shaft 4. Generally, the rotating shaft 4 is above, and the damping assembly 6 is below relative to the rotating shaft 4. The weight of the battery cabinet 1 is mainly conducted to the vehicle body through the rotating shaft 4. The rotating shaft 4 can be at a certain distance from the center of mass of the battery cabinet 1, or can coincide with the center of mass of the battery cabinet 1.

[0035] The battery cabinet 1 is installed on the side of the vehicle body through the rotating shaft 4 and the damping assembly 6. When the vehicle body shakes, the shaking of the vehicle body can be divided into two categories. Small amplitude shaking of the vehicle body makes the vehicle body rotate relative to the rotating shaft 4 and then returns to the original position, which has little effect on the battery cabinet 1. When the vehicle shakes greatly, the shaking of the vehicle body is transmitted to the battery cabinet 1 through the rotating shaft 4 or other transmission paths because the rotating shaft 4 cannot completely eliminate all shaking. The battery cabinet 1 rotates multiple times compared with the rotating shaft 4. The damping assembly 6 functions to dampen the rotating motion after the rotating shaft 4 has converted the shaking into rotating motion around it. The damping assembly 6 is spaced apart from the rotating shaft 4 by a certain distance. The damping assembly 6 has enough torque compared with the rotating shaft 4 to offset the rotating motion, thereby greatly reducing the vibration of the battery cabinet 1 and meeting the requirement of loading more batteries. Embodiment two

[0036] The present embodiment provides a mounting structure of a battery cabinet. The present embodiment is optimized on the basis of embodiment one to improve technical effects and refine technical solutions. The contents not described in detail in the present embodiment are described in detail in embodiment one.

[0037] Different vehicles have different shaking amplitudes when driving, and the shaking amplitudes are different when the vehicles drive on different road conditions. If the distance between the rotating shaft 4 and the damping assembly 6 is not appropriate, the damping effect may be reduced and the service life of the mounting structure may be rapidly reduced. As one of the embodiments, reference is made to Figure 1 The mounting structure of the battery cabinet further includes a support frame 3. The battery cabinet 1 includes a mounting plate 2, which can be arranged on the side of the battery cabinet 1. The mounting plate 2 can be extended from the support frame of the battery cabinet 1. The mounting plate 2 is provided with a plurality of mounting positions with different positions. The support frame 3 is connected to the mounting position of the mounting plate 2 at a suitable position. The support frame 3 is provided with a mounting hole. The rotating shaft 4 is inserted into the mounting hole and connected to the support frame 3. By adjusting the mounting position of the support frame 3, the distance between the support frame 3 and the damping assembly 6 is adjusted. The support frame 3 itself also helps to create a certain gap between the battery cabinet 1 and the rotating shaft 4 and the vehicle body, preventing the battery cabinet 1 from touching the vehicle body when rotating.

[0038] As one of the embodiments, the support frame 3 can also be arranged on the mounting plate 2, so that the stress between the support frame 3 and the damping assembly 6 is transmitted through as few components as possible.

[0039] As known above, the rotating shaft 4 is connected to the vehicle body in a rotating manner, and the connection between the rotating shaft 4 and the support frame 3 will be determined according to the requirements. As one of the embodiments, reference is made to Figure 4 The rotating shaft 4 is connected to the support frame 3 in a rotating manner. The end of the rotating shaft 4 is provided with a retaining ring 5 for preventing the support frame 3 from being pulled out of the support frame 3. It can be predicted that under the action of vibration, if the support frame 3 slides to the end relative to the rotating shaft 4, the retaining ring 5 will block the support frame 3, thereby maintaining stability. This scheme is suitable for the case where the support frame 3 has strong wear resistance.

[0040] In other non-limiting embodiments of the present application, with reference to Figure 4 and Figure 6 the rotation shaft 4 is fixedly connected with the support frame 3, and the two are further fixedly connected through a rib plate 3.1, which is used to strengthen the structural strength between the rotation shaft 4 and the support frame 3, so that the wear of rotation occurs at the side of the vehicle body.

[0041] As one of the embodiments, with reference to Figure 3 and Figure 6 the damping assembly 6 includes a support plate 6.1 and a damper 9, the end of the support plate 6.1 is supported and connected with the mounting position of the mounting plate 2 through bending, so as to bear the overload and reaction force in the damping process from the end, and the bending of the support plate 6.1 forms a raised surface away from the mounting plate 2, and the damper 9 is arranged on the raised surface of the mounting plate 2. In use, the end of the support plate 6.1 converges the shaking to the damper 9 on the raised surface, and the damper 9 generates a reverse rotating force to the shaking, which is transmitted from the raised surface to the battery cabinet 1 through the end of the support plate 6.1 to offset the shaking.

[0042] The above only introduces the performance of the damping assembly 6 at the side of the battery cabinet 1, as one of the embodiments, with reference to Figure 1 , Figure 3 and Figure 6 at the side of the vehicle body, the damping assembly 6 further includes a force transmission bracket 11 for mounting on the vehicle body, one end of the force transmission bracket 11 away from the vehicle body is fixedly connected with a contact plate 6.2, and in use, the contact plate 6.2 is in elastic contact with the damper 9 to slow down the vibration of the battery cabinet 1. Specifically, the shaking of the battery cabinet 1 is transmitted from one or more dampers 9 to the same contact plate 6.2, and then transmitted to the vehicle body by the contact plate 6.2 through the force transmission bracket 11. At this time, the damper 9 is elastically compressed, that is, it absorbs part of the shaking, and when the compression force generated by the shaking / rotation on the damper 9 exceeds the peak value, the damper 9 elastically releases, and the reaction of the elastic release offsets another part of the shaking, and at the same time, the reaction of the elastic release of the damper 9 is transmitted and supported on the vehicle body side through the contact plate 6.2 and the force transmission bracket 11.

[0043] As one of the embodiments, the damper 9 is made of rubber material.

[0044] As one of the embodiments, the damping direction of the damping assembly 6 coincides with the rotation direction of the damping assembly 6 around the rotation shaft 4, so as to maximize the damping performance of the damper 9. For example, with reference to Figure 1 and Figure 2, the rotating shaft 4 is arranged along the lateral side of the vehicle body parallel to the horizontal plane, the force transmission bracket 11 is also parallel to the horizontal plane but perpendicular to the rotating shaft 4, and the damping assembly 6 is radially perpendicular to the rotating shaft 4; in use, the shaking of the battery cabinet 1 will be concentrated at the damping assembly 6 as reciprocating vibration around the rotating shaft 4, at this time, the force transmission bracket 11 can effectively support the shaking of the battery cabinet 1 and the elastic release of the damper 9. The direction of the maximum elastic potential of the damper 9 can also be arranged in the same direction as the force transmission bracket 11, and the contact plate 6.2 is perpendicular to the direction, and the support plate 6.1 is raised in the direction.

[0045] It is worth noting that, Figure 1 In order to facilitate explanation, the corresponding contact plate 6.2 and force transmission bracket 11 are drawn on one side of the damper 9, and the damper 9 on the other side is hidden as a contrast, and the contact plate 6.2 and the force transmission bracket 11 are not drawn. In normal use, the contact plate 6.2 and the force transmission bracket 11 are on the side of the vehicle body, and the damper 9 is on the side of the battery cabinet 1. The damper 9 and the contact plate 6.2 are in elastic contact after the damper 9 and the contact plate 6.2 are aligned.

[0046] It is worth noting that when the vibration amplitude is large, the battery cabinet 1 may swing to the side of the vehicle body at a large angle around the rotating shaft 4, which will cause the damping assembly 6 to be hit hard. In order to reduce the degree of impact, reference Figure 1 、 Figure 3 and Figure 6 As one of the embodiments, the damper 9 is provided with an inner hole, which can be realized by adopting an annular damper 9; and the contact plate 6.2 is connected with the support plate 6.1 through the second bolt 10, and the connection point of the second bolt 10 is located in the inner hole of the damper 9. The tightness between the contact plate 6.2 and the damper 9 is adjusted by adjusting the amount of wire of the second bolt 10. By adjusting the tightness between the contact plate 6.2 and the damper 9 to an appropriate range through the second bolt 10, the impact on the damping assembly 6 can be reduced.

[0047] As one of the embodiments, reference Figure 2 and Figure 4 The mounting structure of the battery cabinet further includes a connectable sleeve 7, which is used to be mounted on the vehicle body. In use, the rotating shaft 4 is sleeved into the connectable sleeve 7 to realize the rotating connection between the rotating shaft 4 and the vehicle body, and when the battery cabinet 1 needs to be disassembled, the rotating shaft 4 is disassembled from the connectable sleeve 7.

[0048] A hole can be opened on the side of the vehicle body, and then the connectable sleeve 7 is fixedly mounted on the side of the vehicle body to realize the modification.

[0049] As one of the embodiments, the connectable sleeve 7 includes a plurality of connected frame bodies 7.1, such as Figure 2 and Figure 4In the embodiment, the single connecting sleeve 7 comprises two mutually adhered connecting frame bodies 7.1, the connecting frame bodies 7.1 are provided with transmission grooves matched with the rotating shaft 4, and the two mutually adhered connecting frame bodies 7.1 form a structure capable of being rotationally connected with the rotating shaft 4; on the side of the transmission grooves, each connecting frame body 7.1 is provided with a corresponding first bolt hole, and the first bolts 8 are simultaneously inserted into the plurality of first bolt holes to strengthen the adhesion between the connecting frame bodies 7.1 from the two sides of the rotating shaft 4, the opening and closing of the connecting sleeve 7 is realized by adjusting the insertion amount of the first bolts 8, and the friction between the connecting sleeve 7 and the rotating shaft 4 can also be controlled by adjusting the insertion amount of the first bolts 8.
