Description

Technical Field

[0001] The utility model belongs to the technical field of vehicle frames, and in particular relates to a modular vehicle frame with integrated battery cells and a vehicle. Background Art

[0002] Existing vehicle frame structures are either a load-bearing body-on-frame structure, where the body is integrated into a single unit and then assembled with an independent power battery pack. Alternatively, a non-load-bearing frame-on-body structure is integrated into the body and then assembled with an independent power battery pack. Vehicles with a complete body-on-body or a frame-on-independent power battery pack assembly have lower integration, modularity, and lightweight coefficients.

[0003] The existing patent number is CN202223202812.3, a modular chassis frame for electric vehicles and an electric vehicle. Although it is disclosed that the frame is assembled in a modular form, the mid-section module of the frame is designed to be a sunken structure, which reduces the height of the vehicle beam threshold. The mid-section module of the frame forms a larger battery installation space, freeing up more space inside the vehicle. In order to make room for the battery installation, the above-mentioned mid-section module of the frame needs to be designed as a sunken structure. Lowering the vehicle threshold has advantages and disadvantages. Since the sunken structure of the mid-section module of the frame needs to be assembled and coordinated with the front section module of the frame and the rear section module of the frame, the front section module of the frame and the rear section module require high adaptability and do not have universal characteristics. Secondly, the mid-section module of the frame requires additional battery pack assembly. Therefore, how to maximize the modular assembly improvement of the mid-section module of the frame is a problem that needs to be considered. Utility Model Content

DETAILED DESCRIPTION

[0023] The technical solutions in the embodiments of the present invention are described clearly and completely below. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0024] Example 1:

[0025] This embodiment provides a modular vehicle frame with integrated battery cells, which has high integration performance and integrates the battery cell module with the vehicle frame structure, facilitating the overall transportation of the vehicle frame structure, reducing assembly difficulty, and providing more options for vehicle frame installation space.

In the figure, the transverse direction is the left-right direction, which is parallel to the X direction; the longitudinal direction is the front-back direction, which is parallel to the Y direction. In this embodiment, the front-back direction of the frame corresponds to the forward or reverse direction of the vehicle. The frame is installed in a direction parallel to the vehicle's direction of travel.

[0027] like Figure 2 As shown, this embodiment provides a modular frame with integrated battery cells, including a frame mid-section module 1, a frame front-section module 2 arranged at one end of the frame mid-section module 1, and a frame rear-section module 3 arranged at the other end of the frame mid-section module 1; the frame mid-section module 1 includes a mid-section frame 11, a battery cell module 12 arranged in the mid-section frame 11 and integrally connected thereto, and the side walls of the mid-section frame 11 are provided with a plurality of connecting edges 13, and the frame front-section module 2 and the frame rear-section module 3 are respectively connected and positioned with the corresponding connecting edges 13.

[0028] Example 2:

[0029] This embodiment optimizes the vehicle frame based on the above embodiment, and in particular provides a specific implementation of a vehicle frame mid-section module:

[0030] The mid-section frame module 1 includes a mid-section frame 11, which has a front connecting end 14 and a rear connecting end 15. The front connecting end 14 is connected to the front-section frame module 2, and the rear connecting end 15 is connected to the rear-section frame module 3. The mid-section frame module 1 is connected between the front-section frame module 2 and the rear-section frame module 3, and is used to support and connect the front-section frame module 2 and the rear-section frame module 3. At the same time, it serves as a carrier of the battery module 12 and is used to integrate the battery module 12 with the mid-section frame module 1. The mid-section frame 11 can be a square frame structure, a circular frame structure, an elliptical frame structure or other shapes; the battery module 12 in the mid-section frame 11 is adapted to the structure of the mid-section frame 11, and the battery module 12 and the mid-section frame 11 are connected in an integral manner, specifically, the outer shell of the battery module 12 is welded to the mid-section frame 11.

[0031] The sidewalls of the mid-section frame 11 are provided with several connecting edges 13, one at each of the front and rear connecting ends 14. In this embodiment, the mid-section frame 11 is a rectangular structure. The front connecting end 14 is provided with a protruding support edge 16 along its length, i.e., in the transverse direction. Correspondingly, the rear connecting end 15 is provided with a protruding support edge along its length. The front-section frame module 2 is detachably connected to the connecting edge 13 of the front connecting end 14, and the rear-section frame module 3 is detachably connected to the connecting edge 13 of the rear connecting end 15.

[0032] The connection between the front frame module 2 and the connecting edge 13 of the front connecting end 14, and the connection between the rear frame module 3 and the rear connecting end 15 can be achieved by screwing, riveting, or other methods. In this embodiment, screwing is used to secure the front frame module 2 and the front connecting end 14, and to secure the rear frame module 3 and the rear connecting end 15. Specifically, bolt holes are provided on the connecting edge 13, and both the front frame module 2 and the rear frame module 3 have bolt holes. During assembly of the front frame module 2 and the rear frame module 3, the front frame module 2 is placed against the connecting edge 13 so that the bolt holes on the connecting edge 13 are aligned with the bolt holes on the front frame module 2. Bolts are then passed through the bolt holes in sequence and secured with nuts. Correspondingly, the rear frame module 3 is also screwed to the connecting edge 13 in the same manner as described above.

[0033] Example 3:

[0034] like Figure 3 As shown, this embodiment optimizes the vehicle frame based on the above embodiment, and in particular provides a specific implementation method of the front section module of the vehicle frame:

[0035] The front frame module 2 includes a front bumper beam 21, several front energy absorption boxes 22, and a front connector 23. The front bumper beam 21 is arranged in the transverse direction and has a multi-cavity structure inside, which has an energy-absorbing effect. The front bumper beam 21 can be curved or in other shapes. In this embodiment, the front bumper beam 21 is curved as an example, and is arranged to protrude in the longitudinal direction.

[0036] The front frame module 2 includes at least two front energy absorption boxes 22, which are arranged along the longitudinal direction. The two front energy absorption boxes 22 are spaced apart. The front ends of the front energy absorption boxes 22 are connected to the front anti-collision beam 21, and the front ends of the front energy absorption boxes 22 are oriented in the forward direction of the vehicle. The rear ends of the front energy absorption boxes 22 are connected to the front connector 23, and the rear ends of the front energy absorption boxes 22 are oriented in the reverse direction of the vehicle.

[0037] The interior of the front energy absorbing box 22 is a cavity structure. The front energy absorbing box 22 is a straight tube structure or other shapes. In this embodiment, the front energy absorbing box 22 is a straight tube as an example.

[0038] The number of front crash boxes 22 may be two or more. If the number of front crash boxes 22 is odd, one of the front crash boxes 22 is located on the longitudinal center plane of the front impact beam 21, and the remaining front crash boxes 22 are symmetrically distributed on either side of the longitudinal center plane. The longitudinal center plane is a vertical plane parallel to the Y direction. If the number of front crash boxes 22 is even, the front crash boxes 22 are symmetrically distributed on either side of the longitudinal center plane.

[0039] At least one upper cross-beam 24 is transversely disposed above the front crash boxes 22, and at least one lower cross-beam 25 is transversely disposed below the front crash boxes 22. The upper cross-beam 24 is positioned adjacent to the front anti-collision beam 21, while the lower cross-beam 25 is positioned adjacent to the front connector 23. The upper cross-beam 24 and the lower cross-beam 25 assemble the front crash boxes 22 into a frame structure, enhancing the assembly stability and connection strength of the front frame module 2.

[0040] The front section connecting member 23 is connected to the connecting edge 13 of the middle section frame 11. The front section module 2 and the middle section module 1 of the frame are symmetrically arranged along the longitudinal center plane.

[0041] Example 4:

[0042] like Figure 4 As shown, this embodiment optimizes the vehicle frame on the basis of the above embodiment, and in particular provides a specific implementation method of the rear section module of the vehicle frame:

[0043] The rear frame module 3 includes a rear anti-collision beam 31, several rear energy absorption boxes 32, and rear connectors 33. The rear frame module 3 has the same or substantially the same structure as the front frame module 2. The rear connectors 33 are connected to the connecting edge 13 of the mid-frame 11. The rear frame module 3 is symmetrically arranged with the mid-frame module 1 along the longitudinal center plane.

[0044] The structural difference between the rear section module 3 of the frame and the front section module 2 is that a number of fixed cross beams 34 are arranged between the rear section energy absorption boxes 32. The fixed cross beams 34 are arranged in the transverse direction. The ends of the fixed cross beams 34 are connected to the rear section energy absorption boxes 32. The connection method can be welding, screw connection, or other connection methods. The fixed cross beams 34 increase the connection stability of the rear section module 3 of the frame.

[0045] Embodiment 5:

[0046] This embodiment provides a vehicle, comprising the modular frame with integrated battery cells in the above embodiment.

[0047] When the above embodiment is applied, the front section module 2, the middle section module 1 and the rear section module 3 of the frame are assembled and connected. The front section module 2 and the rear section module 3 of the frame are fixed by connecting to the connecting edge 13 of the middle section module 1, which reduces the difficulty of assembling the entire frame, and makes the front section module 2 and the rear section module 3 highly versatile and can be adapted to different middle section modules 1 of the frame. Since the middle section module 1 integrates the battery module, when different battery modules need to be adapted, it can be achieved by replacing different middle section modules 1. The modular frame assembly method brings a lot of convenience.
