Description

Vehicle body assembly and vehicle

Technical Field

The utility model relates to the technical field of arrangement of components on a vehicle body, and particularly provides a vehicle body assembly and a vehicle.

Background

More and more automobile bodies in the market at present adopt cast integrated structures. However, the overall structure of the cast integrated vehicle body and the stress condition thereof under the collision condition are different from those of the conventional vehicle body with the stamping structure, and in addition, due to the expansion requirement of the front cabin as a storage space and the integrated arrangement of the air conditioning system in the front cabin of the vehicle body, more strict requirements are put on the arrangement of related structures/modules/systems in the front cabin. The brake control unit (such as ESP, RBU, etc.) is used as a rigid structure with larger volume inside the front cabin, and the arrangement mode inside the front cabin has larger influence on the safety performance when the whole vehicle collides.

In general, the brake control unit is disposed inside the front compartment, specifically, at a region between the rear portion of the side sill assembly and the front portion of the dash panel. However, during the development of the NPD (New Product Development ) platform, simulation analysis has found that, in the case of a cast-in-one body structure, in which the brake control unit adopts this arrangement, during a collision of the vehicle, the brake control unit may have a great impact on the integrally cast body under the compression of the compressor of the air conditioning system, thereby causing unacceptable damage.

The vehicle body 1 includes a dash panel 11, a region behind the dash panel 11 is a cabin of the vehicle, a region in front of the dash panel 11 is a cabin space of the vehicle, the motor 2, the motor controller 3 and the brake control assembly 4 are all disposed in the cabin space, the RBU is used as a secondary brake control unit of a control system of the vehicle, and a main brake control unit of the vehicle is associated with a brake pedal in the cabin.

In one possible embodiment, a first space 5 is formed between the front portion of the dash panel 11 and the rear portion of the motor 2, and the brake control assembly 4 is provided in the first space 5. The holder assembly 41 is formed with a second space 6, and at least a portion of the rbu42 is accommodated in the second space 6.

In one possible embodiment, the RBU42 is located approximately in the middle of the front compartment space (as adapted to the position of the motor) in the Y-direction of the vehicle, and the motor controller is disposed above the motor. In this way, the arrangement scheme of the RBU can ensure that the pipeline distance between the main brake control unit and the auxiliary brake control unit (the main brake control unit is associated with a brake pedal, and the RBU is the auxiliary brake control unit) of the left/right rudder vehicle type is short, so that the arrangement scheme can realize the generalization of the left/right rudder vehicle type in the same platform. In other words, the arrangement scheme of the utility model can ensure that the pipeline distance between the main brake control unit and the auxiliary brake control unit is short no matter aiming at the left rudder vehicle type or the right rudder vehicle type.

Referring primarily to fig. 3-5, in one possible embodiment, the bracket assembly 41 is made by means of a press weld. Specifically, the bracket assembly 41 includes a first portion 411 and a second portion 412, wherein the first portion 411 and the second portion 412 are both manufactured by stamping and are connected to each other by welding. In the coupled state, the first part 411 and the second part 412 form a second space 6 for accommodating the RBU 42.

In one possible embodiment, the first portion 411 includes a first sub-portion 4111 and a second sub-portion 4112, and the first sub-portion 4111 is mainly configured to form the aforementioned second space 6 for accommodating a portion of the RBU42 with the second portion 412, and the connection relationship between the bracket assembly 41 and the vehicle body 1 is mainly represented by the position of the bracket assembly 41 corresponding to the second sub-portion 4112.

In one possible embodiment, a portion of the outer edge of the first portion 411 extends with a flange 4113, the flange 4113 and the second portion 412 forming a closed loop generally along the circumference of the first portion 411.

In one possible embodiment, the first sub-portion 4111 has a generally rectangular configuration and the second portion 412 is disposed in a position of the bracket assembly 41 corresponding to one of the sides of the rectangular configuration. The first sub-portion 4111 and the second portion 412 are connected to each other by welding.

In one possible embodiment, the second portion 412 includes a main body portion 4121, an upper outer edge of the main body portion 4121 is extended with a mounting portion 4122 in a direction toward the flange 4113, and the rbu42 is coupled to the main body portion 4121 and the mounting portion 4122 by screwing, respectively. As in the present example, RBU42 is threaded (denoted as A1) with a central location of body portion 4121. The mounting portion 4122 is provided with two threaded locations (designated as A2, A3) that are generally triangularly disposed so that the RBU42 and the body portion 4121 are connected to one another by a stable three-point threaded connection. To ensure the reliability of the bracket assembly 41, the mounting portion 4122 is also connected to the flange 4113 by welding (denoted B1).

Illustratively, the main body portion 4121 also has an extended end 4123 on one side in the width direction thereof and on the bottom outer edge thereof in a direction toward the flange 4113, and the respective positions of the extended end 4123 and the second portion 412 are connected to each other by welding (denoted as B2, B3). In this example, the welding locations between the two projecting ends 4123 and the aforementioned mounting portion 4122 and flange 4113 also form a generally triangular arrangement. In this way, the first portion 411 and the second portion 412 can be connected to each other by a stable three-point welding.

Illustratively, the second sub-portion 4112 is provided with three threaded locations (denoted C1, C2, C3, respectively) that also form a generally triangular arrangement. In this way, the bracket assembly 41 and the bottom of the vehicle body 1 can be connected to each other by means of a stable three-point screw connection at a position corresponding to the first space 5.

In summary, in the preferred embodiment of the present utility model, by disposing the RBU42 in the first space, the arrangement does not affect the peripheral members of the existing layout on the premise that the space formed between the (front) motor and the middle tunnel at the front of the dash panel is fully utilized. On this basis, since the first space provides a sufficient collision buffering space for the RBU42, the problem of an increase in the intrusion amount of the RBU42 into the vehicle body due to its layout scheme can be greatly reduced in the event of a collision of the vehicle, thereby satisfying the collision safety requirements of the vehicle. Meanwhile, as the RBU is approximately positioned in the middle of the front cabin space along the Y direction of the vehicle, the arrangement scheme of the RBU can ensure that the pipeline distance between the main brake control unit and the auxiliary brake control unit is short for both the left steering vehicle type and the right steering vehicle type, and therefore the generalization of the left steering vehicle type and the right steering vehicle type is realized. In addition, on the basis of adopting the support assembly of new design, the installation reliability of RBU in the second space and the installation reliability of RBU that contains the support assembly in the first space can be guaranteed.
