The controller installation device is located between the front hanger fixing plate and the rear hanger fixing plate. The controller installation device is composed of a front installation plate and a rear installation plate. The utility model facilitates the installation of the electric vehicle controller. This structure enables the controller to be built-in, reduces the risk of damage due to the exposure of the controller, and this structure facilitates the connection of the storage battery and the controller, and can ensure the stability of line transmission.

[0004] When a collision occurs or when driving on a bumpy road section, the controller is easily subjected to force extrusion, resulting in damage to the components. The above device only protects the housing and the like, and cannot comprehensively protect the controller. Content of the Utility Model

[0005] Based on this, the purpose of the present utility model is to provide an installation structure for an electric vehicle controller to solve the technical problems raised in the above background technique.

[0006] To achieve the above purpose, the present utility model provides the following technical solutions:

[0007] An installation structure for an electric vehicle controller includes two-end positioning components, a main force-bearing component, and an auxiliary protection component. The two-end positioning components include a positioning bottom plate. At one end of the top of the positioning bottom plate, side limiting columns are symmetrically provided. At the other end of the top of the positioning bottom plate, a fixed side plate is provided;

[0008] The main force-bearing component includes a main force-bearing long rod. At both ends of the main force-bearing long rod, clamping structures are symmetrically provided. On both sides of the main force-bearing long rod and on one side of the clamping structure, at least two groups of side connecting rods are symmetrically provided;

[0009] The auxiliary protection component includes a controller placement base plate, and at least two groups of controller positioning blocks are symmetrically arranged on both sides of the controller placement base plate.

[0010] Preferably, first bending angles are symmetrically arranged at both ends of the controller placement base plate, and second bending angles are arranged on one side of the first bending angles at both ends of the controller placement base plate; at least four positioning and mounting holes are arranged at both ends of the top of the controller placement base plate.

[0011] Preferably, the first bending angle bends towards the bottom direction of the controller placement base plate, and the second bending angle bends towards the top of the controller placement base plate;

[0012] The first bending angle and the second bending angle have the same bending angle, and the bending angle is 160 degrees.

[0013] Preferably, at least one controller mounting hole is penetrated through the top of the controller positioning block.

[0014] Preferably, arc-shaped stress structures are arranged on both ends of the main stress long rod and close to one side of the clamping structure, and long rod mounting holes are symmetrically penetrated through both ends of the main stress long rod.

[0018] To sum up, the technical solution mainly has the following beneficial effects:

[0019] 1. In the utility model, the whole device is fixed through the positioning components at both ends. By adopting the positioning method at both ends, the stress points are reduced from the traditional multiple methods to two entry points. When the device is stressed, the waist end bending angle is stressed first to offset part of the acting force, and then the remaining acting force is transmitted to the main stress long rod through the arc-shaped stress structure. The main stress long rod is in the state of bearing most of the stress. When the stress is not enough to deform the main stress long rod, the electric vehicle controller will not be damaged;

[0020] 2. Additionally, when the force exceeds the bearing limit of the main load-bearing long rod, since the main load-bearing long rod is connected to the controller mounting base through the side connection support rods, the excessive force is transmitted to the controller mounting base by the side connection support rods. The first bending angle and the second bending angle provided at both ends of the controller mounting base are subjected to the force and first bend towards the bottom, further protecting the controller from the force.

[0029] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model.

[0030] Embodiment

[0031] As Figure 1 , 3, as shown in FIGS. 6 and 7, an installation structure for an electric vehicle controller includes end positioning components 10. The end positioning components 10 include a positioning base plate 11. At one end of the top of the positioning base plate 11, side limiting columns 12 are symmetrically arranged, and at the other end of the top of the positioning base plate 11, a fixed side plate 13 is provided;

[0032] A long rod positioning hole 111 is provided through the top of the positioning base plate 11, and the long rod positioning hole 111 is correspondingly arranged with the long rod installation hole 212; at least two sheet metal installation holes 131 are provided at the top of the side wall of the fixed side plate 13, and a waist end bending angle 132 is provided at the side wall of the fixed side plate 13 and at the bottom of the sheet metal installation hole 131.

[0033] It should be noted that in this embodiment, the end positioning components 10 are fixed at the installation position to be installed by bolts and nuts through the two sheet metal installation holes 131 at the top of the side wall of the fixed side plate 13, and at the same time, the rotation of the whole component is prevented. Among them, the long rod positioning hole 111 is provided on the positioning base plate 11, and the long rod positioning hole 111 and the long rod installation hole 212 are also fixed together by bolts and nuts;

[0034] Among them, after being installed in the groove, the clamping structure 22 contacts the side limiting column 12, and the side limiting column 12 limits the clamping structure 22.

[0035] When an external force acts, the fixed side plate 13 is first affected by the acting force. After the acting force reaches the material bearing limit of the fixed side plate 13, the waist end bending angle 132 on the fixed side plate 13 is affected by the external force and preferentially deforms to completely offset a small part of the acting force, which is the first protection of the mechanism for the controller.

[0036] As Figure 1 、 2 , as shown in FIGS. 2, 3, and 4, the main force-bearing component 20 includes a main force-bearing long rod 21. Clamping structures 22 are symmetrically arranged at both ends of the main force-bearing long rod 21. At least two groups of side connection support rods 23 are symmetrically arranged on both sides of the main force-bearing long rod 21 and on one side of the clamping structure 22;

[0037] Arc-shaped stress structures 211 are arranged on both ends of the main force-bearing long rod 21 and on one side close to the clamping structure 22. Long rod installation holes 212 are symmetrically provided through both ends of the main force-bearing long rod 21; installation base plate positioning holes 231 are provided through the top of the side connection support rods 23, and the number and positions of the installation base plate positioning holes 231 correspond to those of the positioning installation holes 313.

[0038] It should be noted that, in this embodiment, the force that cannot be completely offset is transmitted to the arc-shaped force-bearing structure 211 at both ends of the main force-bearing long rod 21 through the fixed side plate 13, wherein the top of the arc-shaped force-bearing structure 211 is set in an arc shape, and the force receiving point is single, so that the external force is transferred to the main force-bearing long rod 21 as much as possible. The main force-bearing long rod 21 serves as a second line of protection to offset the forces from both ends, and further prevent the external force from affecting the controller;

[0039] Furthermore, even though the main force-bearing long rod 21 deforms when it reaches its material bearing limit, due to its structural reasons, the force is transmitted to the side connecting support rods 23 on both sides thereof, and then transmitted to the controller mounting base plate 31 of the structure through the side connecting support rods 23. The controller is fixed on the top thereof through the controller mounting holes 321 on both sides of the controller mounting base plate 31.

[0040] like Figure 1 , 5 6, the auxiliary protection assembly 30, the auxiliary protection assembly 30 includes a controller placement base plate 31, at least two groups of controller positioning blocks 32 are symmetrically arranged on both sides of the controller placement base plate 31; first bending angles 311 are symmetrically arranged at both ends of the controller placement base plate 31, and second bending angles 312 are arranged at both ends of the controller placement base plate 31 and on one side of the first bending angle 311; at least four positioning and mounting holes 313 are arranged at both ends of the top of the controller placement base plate 31;

[0041] The first bending angle 311 is bent toward the bottom of the controller placement base plate 31, and the second bending angle 312 is bent toward the top of the controller placement base plate 31;

[0042] The first bending angle 311 and the second bending angle 312 have the same bending angle, and the bending angle is 160 degrees. At least one controller mounting hole 321 is formed on the top of the controller positioning block 32 .

[0043] It should be noted that, in the present embodiment, the controller mounting base plate 31 is the third line of protection, and its cross-section is trapezoidal, with a first bending angle 311 and a second bending angle 312. When subjected to force, the first bending angle 311 bends toward the bottom of the controller mounting base plate 31 and the second bending angle 312 bends toward the top of the controller mounting base plate 31, thereby offsetting the external force and avoiding the influence of the controller body arranged on the top of the controller mounting base plate 31 by its own deformation, thereby further ensuring the integrity of the controller components.

[0044] The working principle of the utility model is:

[0045] Fix the two sheet metal mounting holes 131 at the top of the side wall of the fixed side plate 13 with bolts and nuts to fix the two end positioning components 10 at the installation position to be installed, and at the same time prevent the whole component from rotating. Among them, the positioning bottom plate 11 is provided with long rod positioning holes 111, and the long rod positioning holes 111 and the long rod mounting holes 212 are also fixed together with bolts and nuts;

[0046] Among them, after being installed in the groove, the clamping structure 22 contacts the side limit strut 12, and the side limit strut 12 limits the clamping structure 22;

[0047] When an external force acts, the fixed side plate 13 is first affected by the acting force. After the acting force reaches the material bearing limit of the fixed side plate 13, the waist end bending angle 132 on the fixed side plate 13 is affected by the external force and preferentially deforms to completely offset a small part of the acting force, which is the first protection of this mechanism for the controller;

[0048] Subsequently, the acting force that cannot be completely offset is transmitted from the fixed side plate 13 to the arc-shaped stress-bearing structures 211 at both ends of the main stress-bearing long rod 21. Among them, the top of the arc-shaped stress-bearing structure 211 is set in an arc shape, and the force-receiving point is single, and the external acting force received is transferred to the main stress-bearing long rod 21 as much as possible. The main stress-bearing long rod 21 is used as the second protection to offset the acting force from both ends and further prevent the external acting force from affecting the controller;

[0049] Furthermore, although the main stress-bearing long rod 21 deforms when it reaches the material bearing limit, due to its structural reasons, the force is transmitted to the side connection struts 23 on both sides of it, and is conducted to the controller placement bottom plate 31 of this structure through the side connection struts 23. The controller is fixed on its top through the controller mounting holes 321 on both sides of the controller placement bottom plate 31;

[0050] The controller placement bottom plate 31 is the third protection. Its cross-section is trapezoidal, and the first bending angle 311 and the second bending angle 312 are provided. When stressed, the first bending angle 311 bends towards the bottom of the controller placement bottom plate 31 and the second bending angle 312 bends towards the top of the controller placement bottom plate 31. While offsetting the external acting force, its own deformation avoids affecting the controller body arranged on the top of the controller placement bottom plate 31, and further ensures the integrity of the controller components.

[0051] The above embodiments are only used to illustrate the technical idea of the present invention, and the protection scope of the present invention cannot be limited by this. Any modification made on the basis of the technical solution according to the technical idea proposed by the present invention falls within the protection scope of the present invention.
