Description

Technical Field

[0001] The utility model relates to the technical field of electric vehicle frames, in particular to an electric vehicle frame structure. Background Art

[0002] The frame of an electric vehicle is a crucial component, connecting all of its components to form a cohesive whole. For example, it connects the motor and wheels, allowing the motor's power to be transmitted to the wheels, propelling the vehicle forward. The frame also connects to the shock absorbers.

[0003] During the installation of the electric vehicle frame and shock absorber, if the installation angle of the shock absorber deviates, the compression and rebound stroke of the shock absorber will be affected, thereby reducing the shock absorption effect. Figure 1 , is a connection structure between the electric vehicle frame body 1 and the shock absorber 8 in the related technology, which includes a bolt 5, a nut 6 and a sleeve 7, etc. The sleeve 7 is first passed through the electric vehicle frame body 1, and the mounting end of the shock absorber 8 is abutted on the sleeve 7. The bolt 5 passes through the sleeve 7 and the mounting end of the shock absorber 8 in sequence, and then the nut is threadedly connected to the bolt 5.

[0004] However, in the above technical solution, the sleeve 7, bolt 5 and nut 6 all play a role in installing and positioning the shock absorber 8 on the electric vehicle frame body 1. Therefore, high manufacturing and installation precision are required for the above components. If the part size and installation position of the above components deviate, the installation position of the shock absorber 8 on the electric vehicle frame body 1 will deviate, resulting in low installation efficiency between the shock absorber 8 and the electric vehicle frame and increased production costs. Utility Model Content

[0005] In order to improve the installation efficiency of the shock absorber on the electric vehicle frame, the present application provides an electric vehicle frame structure.

[0006] The electric vehicle frame structure provided in this application adopts the following technical solution:

[0007] An electric vehicle frame structure includes a frame body, a connector body and two limit plates, one end of the connector body is fixedly connected to the frame body, and the two limit plates are respectively fixedly connected to the end of the connector body away from the frame body. The two limit plates are respectively provided with through holes. When the shock absorber is installed on the connector body, the two limit plates respectively abut against the two sides of the shock absorber installation end.

[0008] By adopting the above technical solution, the mounting end of the shock absorber is placed between the two limit plates, so that the two limit plates locate and limit the position of the mounting end of the shock absorber. The matching bolts are passed through the through holes of the two limit plates and the mounting end of the shock absorber at the same time, and the nuts are threadedly connected to the bolts, and the bolts and nuts are simultaneously abutted against the limit plates on both sides to complete the installation of the shock absorber; the installation of the shock absorber is made more convenient, and the requirements for bolts and nuts are greatly reduced. At the same time, the possibility of wear on the mounting end of the shock absorber during the installation process is reduced, thereby improving the installation efficiency of the shock absorber on the electric vehicle frame.

[0009] Preferably, a matching groove that can match with the frame body is formed at one end of the connector body close to the frame body, and when the connector body is installed on the frame body, the matching groove matches with the frame body.

[0010] By adopting the above technical solution and providing the matching groove, it is convenient to install the frame body onto the vehicle body, thereby increasing the connection area between the frame body and the connection body, thereby improving the strength and stability of the connection, reducing stress concentration and deformation at the connection part, and reducing the risk of connection failure.

[0011] Preferably, the connector body is arranged in an "S"-shaped structure from one end close to the matching groove to one end close to the limiting plate.

[0012] By adopting the above technical solution, the "S"-shaped structure can disperse stress. When subjected to external force, the "S" shape can transmit and disperse the force along the curve, avoiding stress concentration at a certain point, and can bear the load more evenly, thereby improving the overall structural strength.

[0013] Preferably, bending parts are respectively provided on both sides of the connecting member body, and the two bending parts are respectively bent from both sides of the connecting member body, one end of the two bending parts is fixedly connected to the frame body, and the two limiting plates are respectively fixedly connected to the two bending parts.

[0014] By adopting the above technical solution and providing a bent portion, the rigidity of the structure is increased, so that the connector body can better adapt to forces in different directions, disperse the forces to different parts, reduce the possibility of deformation of the connector body under force, and increase the connection area with the frame body, thereby improving the firmness of the connection.

[0015] Preferably, the two limiting plates are integrally formed with the corresponding bending portions, and the connection between the two limiting plates is rounded and smoothly transitioned.

[0016] By adopting the above technical solution, the stress concentration between the limiting plate and the bending part is reduced, the connection strength between the limiting plate and the bending part and the service life of the limiting plate are improved.

[0017] Preferably, the corners of the two limiting plates are rounded and smoothly transitioned.

[0018] By adopting the above technical solution, the possibility of sharp edges and corners damaging the surface of the shock absorber mounting end during the shock absorber installation process is reduced; at the same time, the rounded corners also serve as a guide, making it easier to insert the shock absorber mounting end between the two limit blocks, thereby improving the installation efficiency of the shock absorber on the electric vehicle frame.

[0019] Preferably, a plurality of reinforcing plates are provided on the connector body, and the plurality of reinforcing plates are fixedly connected to the limiting plates on both sides at the same time.

[0020] By adopting the above technical solution, the setting of the reinforcement plate can enhance the structural strength and improve the structural stability; before the shock absorber is installed, the setting of the reinforcement plate can reduce the possibility of position changes between the two limit plates caused by deformation of the bending parts on both sides, thereby improving the installation efficiency of the shock absorber on the electric vehicle frame.

[0021] The technical effects of this utility model are mainly reflected in the following aspects:

[0022] 1. The utility model provides a connecting member body and two limiting plates, and places the mounting end of the shock absorber between the two limiting plates, so that the two limiting plates locate and limit the position of the mounting end of the shock absorber. The adapted bolts are passed through the through-holes of the two limiting plates and the mounting end of the shock absorber at the same time, and then the nuts are threadedly connected to the bolts. The bolts and nuts are simultaneously abutted against the limiting plates on both sides to complete the installation of the shock absorber. This makes the installation of the shock absorber more convenient, and greatly reduces the requirements for bolts and nuts. At the same time, the possibility of wear on the mounting end of the shock absorber during the installation process is reduced, thereby improving the installation efficiency of the shock absorber on the electric vehicle frame.

[0023] 2. The utility model provides a matching groove to facilitate the installation of the frame body onto the vehicle body, thereby increasing the connection area between the frame body and the connection body, thereby improving the strength and stability of the connection, reducing stress concentration and deformation at the connection part, and reducing the risk of connection failure;

[0024] 3. The utility model increases the rigidity of the structure by providing a bending portion, so that the connector body can better adapt to forces in different directions, disperse the forces to different parts, reduce the possibility of deformation of the connector body under stress, and increase the connection area with the frame body, thereby improving the firmness of the connection.

[0031] The following is combined with Figure 1-5 The present application is further described in detail to make the technical solution of the present application easier to understand and grasp.

[0032] The embodiment of the present application discloses a frame structure of an electric vehicle.

[0033] Reference Figure 2-Figure 4 , an electric vehicle frame structure of this embodiment includes a frame body 1, a connecting member body 2 and two limiting plates 3, one end of the connecting member body 2 is fixedly connected to the frame body 1, and a matching groove 21 is provided which can cooperate with the frame body 1. When the connecting member body 2 is installed on the frame body 1, the matching groove 21 cooperates with the frame body 1, and the surface of the matching groove 21 is fixedly connected to the frame body 1; both sides of the connecting member body 2 are fixedly connected with a bent portion 22, and the two bent portions 22 are respectively bent from the two sides of the connecting member body 2, and the two bent portions 22 are close to the matching groove 21. The two limiting plates 3 are respectively fixedly connected to the ends of the two bent portions 22 away from the frame body 1, and the two limiting plates 3 are respectively provided with a through hole 31, and the two through holes 31 are coaxially arranged. When the shock absorber 8 is installed on the connecting member body 2, the two limiting plates 3 respectively abut against the two sides of the mounting end of the shock absorber 8.

[0034] Reference Figure 2-Figure 4, place the mounting end of the shock absorber 8 between the two limiting plates 3, so that the two limiting plates 3 locate and limit the position of the mounting end of the shock absorber 8, and pass the adapted bolt 5 through the through-holes 31 of the two limiting plates 3 and the mounting end of the shock absorber 8 at the same time, then thread the nut on the bolt 5, and make the bolt 5 and the nut abut against the limiting plates 3 on both sides at the same time to complete the installation of the shock absorber 8; making the installation of the shock absorber 8 more convenient, and greatly reducing the requirements for the bolt 5 and the nut, and at the same time reducing the possibility of wear on the mounting end of the shock absorber 8 during the installation process, thereby improving the installation efficiency of the shock absorber 8 on the electric vehicle frame.

[0035] Reference Figure 2 and Figure 3 The provision of the mating groove 21 facilitates the installation of the frame body 1 onto the vehicle body 1, increasing the connection area between the frame body 1 and the connecting body, thereby improving the strength and stability of the connection, reducing stress concentration and deformation at the connection site, and lowering the risk of connection failure. The provision of the bent portion 22 increases the rigidity of the structure, allowing the connecting body 2 to better adapt to forces in different directions, distributing the forces to different locations, reducing the possibility of deformation of the connecting body 2 under stress, and increasing the connection area with the frame body 1, thereby improving the firmness of the connection.

[0036] Reference Figure 3-Figure 5 The connector body 2 is arranged in an "S" shape from one end near the mating groove 21 to the end near the limit plate 3. The "S" shape can disperse stress. When subjected to external force, the "S" shape can transmit and disperse the force along the curve, avoiding stress concentration at a single point, and can bear the load more evenly, thereby improving the overall structural strength.

[0037] Reference Figure 3-Figure 5 , the two limit plates 3 are integrally formed with the corresponding bending parts 22, and the connection between the two limit plates 3 and the two limit plates 3 is chamfered and smoothly transitioned. The stress concentration between the limit plates 3 and the bending parts 22 is reduced, thereby improving the connection strength between the limit plates 3 and the bending and the service life of the limit plates 3. The corners of the two limit plates 3 are chamfered and smoothly transitioned. The possibility of sharp corners damaging the surface of the mounting end of the shock absorber 8 during the installation of the shock absorber 8 is reduced; at the same time, the chamfered corners also play a guiding role, making it easier to insert the mounting end of the shock absorber 8 between the two limit plates, so as to improve the installation efficiency of the shock absorber 8 on the electric vehicle frame.

[0038] Reference Figure 5Several reinforcing plates 4 are fixedly connected to the connector body 2. These reinforcing plates 4 are evenly distributed along the surface of the connector body 2, and their ends in the longitudinal direction are simultaneously fixedly connected to the limiting plates 3 on both sides. The provision of the reinforcing plates 4 enhances the structural strength and improves the structural stability. Before the shock absorber 8 is installed, the provision of the reinforcing plates 4 reduces the possibility of positional changes between the two limiting plates 3 caused by deformation of the bent portions 22 on both sides, thereby improving the installation efficiency of the shock absorber 8 on the electric vehicle frame.

[0039] Of course, the above are only typical examples of the present application. In addition, the present application may have many other specific implementation methods. Any technical solutions formed by equivalent replacement or equivalent transformation fall within the scope of protection required by the present application.
