With the gradual improvement of the technical level of a power system of a front cabin of a pure electric vehicle, the noise and vibration of a driving motor during operation are greatly reduced compared with those of a traditional engine, and NVH (noise, vibration and harshness) of other vibration sources cannot be covered, so that the influence of the noise and vibration of the compressor of the front cabin of the current electric vehicle on drivers is obvious, and the compressor is used as a very key part of the front cabin of the electric vehicle, and the fixed form of the compressor can directly influence the arrangement structure of the front end area of the whole vehicle. In addition, NVH (acronym for Noise, Vibration and Harshness Noise, Vibration, Harshness), which is a comprehensive problem for measuring the quality of manufactured vehicles, gives the vehicle user the most immediate and superficial experience. The NVH problem of vehicles is one of the concerns of various large vehicle manufacturing enterprises and component enterprises in the international automotive industry. Statistics show that 1/3 failure problem of the whole automobile is related to NVH problem of the automobile, and nearly 20% of research and development cost of each large company is consumed for solving the NVH problem of the automobile. Therefore, on the basis of not influencing the performance and the cost of other systems, the arrangement form of the compressor in the front cabin is optimized, the damping suspension points of vibration parts such as the compressor and the like are enhanced as much as possible, and the riding experience of customers is improved to the greatest extent.

Detailed Description

The following detailed description of embodiments of the utility model refers to the accompanying drawings. It should be understood that the detailed description and specific examples, while indicating the present invention, are given by way of illustration and explanation only, not limitation.

In the present invention, unless otherwise specified, terms of orientation such as "upper", "lower", "left", "right", "top" and "bottom" used generally refer to the orientation in the state of use of the vehicle. It should be noted that this is only for the convenience of describing the present invention and should not be construed as limiting the present invention.

Furthermore, the terms "first", "second", etc. are used for descriptive purposes only and are not to be construed as indicating or implying relative importance or implicitly indicating the number of technical features indicated.

In the present invention, "a plurality" means at least two, e.g., two, three, etc., unless specifically limited otherwise.

The utility model provides a front cabin structure of a vehicle, which comprises a front cabin frame 10, a driving motor 20 and a compressor 30, wherein the driving motor 20 is connected to the front cabin frame 10, and the compressor 30 is arranged on one side of the driving motor 20 facing to a vehicle cab.

The driving motor 20 is a member that can convert electric energy into mechanical energy to drive the wheels of the electric vehicle to run, and may also be referred to as an electric motor or an electric motor. The compressor 20 is a vehicle air conditioner compressor, which is the heart of a vehicle air conditioner refrigeration system and functions to compress and deliver refrigerant vapor. The vehicle in the technical scheme of this application mainly refers to electric automobile, and the power of compressor 30 among traditional petrol or diesel vehicle is generally provided by petrol and diesel engine, therefore its arrangement is restricted by transmission structure, and compressor 30 generally can only set up the side at the engine, and electric automobile's compressor 30's power can be provided by the battery, consequently can have more nimble arrangement. The front cabin structure of a typical vehicle further includes various components, such as a heat dissipation module, an air guide cover, and a cooling duct, which are necessary to have other functions, and are disposed on the front side of the driving motor 20, i.e., the side facing away from the vehicle cabin. The front frame 10 may include a side member capable of transmitting the front impact of the vehicle to the rear of the vehicle, and wheels and associated accessories are provided on the outer side of the side member.

By providing the compressor 30 at the rear side of the driving motor 20, i.e. the side facing the vehicle cabin, a larger space can be provided for arranging other components such as the front end heat dissipation module, the air guide cover, and the cooling pipeline, so that a larger selection range is provided for selecting the components at the same time, and the vehicle can have better performance. Meanwhile, since the compressor 30 is disposed at the rear side of the driving motor 20, the space between the longitudinal beams is saved, that is, the distance between the longitudinal beams is smaller, so that more options can be provided for the tire and the like disposed at the outer side of the longitudinal beam without increasing the width of the vehicle, for example: the selection of tires having greater widths and the selection of high end configuration components such as double wishbone configurations, air springs, etc. provide further possibilities.

In order to solve the problems of vibration and noise of the driving motor 20, the front cabin structure of the vehicle further includes a first suspension bracket 40, and the driving motor 20 is connected to the front cabin frame 10 through the first suspension bracket 40. The first suspension bracket 40 may have a shock-absorbing structure, and thus coupling the driving motor 20 to the first suspension bracket 40 can reduce transmission of vibration of the driving motor 20 to the front cabin frame 10, and thus can effectively reduce vibration and noise felt by the rider.

At present, with the gradual improvement of the technical level of the power system of the front cabin of the pure electric vehicle, noise and vibration of the driving motor 20 during operation are greatly reduced compared with those of a traditional engine, so that NVH of other vibration sources cannot be covered, and therefore, the influence of the noise and vibration of the front cabin compressor 30 during operation on the current electric vehicle type on the passengers is very obvious.

In order to solve the above problem, as shown in fig. 1 and 2, the compressor 30 is connected to the driving motor 20 through the first suspension bracket 40. The first suspension bracket 40 may be configured to connect the compressor 30 and the driving motor 20 to the front compartment frame 10 at the same time, or may be configured to connect only the compressor 30 and the driving motor 20. By using the damping structure that the first suspension bracket 40 may have, which may be a suspension bushing structure, the compressor 30 is connected to the driving motor 20, and the influence of vibration generated when the compressor 30 operates on the operation of the driving motor 20 is also reduced. The structure of the driving motor 20 should be composed of two parts, namely a stator and a rotor, and meanwhile, the gap between the stator and the rotor is very small, so any vibration influence on the external shell of the driving motor 20 can generate impact to a certain degree on the internal structure of the motor, and the compressor 30 is the largest vibration source except the driving motor 20 in the front cabin of the vehicle and is connected with the driving motor, so that the influence of the compressor 30 on the driving motor 20 is reduced, the running stability and the service life of the driving motor 20 can be greatly improved, and the vibration impact on the driving motor 20 by the compressor 30 can be greatly relieved by fixing the compressor 30 on the first suspension bracket 40 in the technical scheme. The technical scheme of this application still is different from the compressor 30 of traditional motorcycle type at the fixed form of arranging of sub vehicle frame, and in this technical scheme, structural design is more succinct, has avoided the complicated design structure of second order vibration isolation. And meanwhile, most of vibration and noise are absorbed and digested directly through the suspension lining, and the effect is better.

In addition, as shown in fig. 1 and 2, the front cabin structure of the vehicle may further include a second suspension bracket, as shown in fig. 1 and 2, through which the driving motor 20 is connected to the front cabin frame 10. The front frame 10 may further include a sub-frame, etc., and in order to further enhance the connection between the driving motor 20 and the front frame 10, the connection between the driving motor 20 and the front frame 10 may be enhanced by using a second suspension bracket, for example, the driving motor 20 and the sub-frame may be connected by using the second suspension bracket.

However, limited to the structure of the first suspension bracket 40, the structure of the first suspension bracket 40 alone is insufficient to support the installation of the compressor 30, and in order to install the compressor 30 on the first suspension bracket 40, as shown in fig. 2, the front cabin structure of the vehicle further includes a connection plate 50, the connection plate 50 is at least partially connected with the suspension bracket 40, and the compressor 30 is fixedly connected to a side of the connection plate 50 opposite to the first suspension bracket 40. The connection plate 50 may have a plate-like structure having a mounting position to which the compressor 30 is fixed by bolts, and the structure of the connection plate 50 may be matched with the shape of the housing of the driving motor 20 or the housing of the compressor 30 for compact arrangement of the front compartment structure. The connection plate 50 may be bolted to one side of the first suspension bracket 40 opposite to the first suspension bracket 40, i.e., the first suspension bracket 40 is located on one side of the connection plate 50 and the compressor 30 is located on the other side.

The connection plate 50 may have a large area or volume and thus may be unstable only in connection with the first suspension bracket 40, and in order to allow the connection plate 50 to be connected more stably and to reduce vibration, the connection plate 50 may be partially connected to the housing of the driving motor 20, as shown in fig. 2. By partially connecting the connection plate 50 to the housing of the driving motor 20, as shown in fig. 2, the connection plate 50 can be changed from a single-end connection to a two-end connection, and thus can be more stable.

Specifically, as shown in fig. 1, in order to facilitate the connection of the connection plate 50, the connection plate 50 may be connected to the housing of the driving motor 20 and the first suspension bracket 40 by bolts. The connection plate 50 may be provided with bolt holes through which bolts pass, and accordingly, the first suspension bracket 40 and the housing of the driving motor 20 may be provided with connection hole sites through which the bolts are connected.

As a specific embodiment, as shown in fig. 1, the front cabin frame 10 includes a first cross beam and a second cross beam spaced apart from each other along a first direction, and further includes a first longitudinal beam and a second longitudinal beam spaced apart from each other along a second direction, where the first direction is perpendicular to the second direction. The first direction is a width direction of the vehicle, and the second direction is a length direction of the vehicle.

Furthermore, as shown in fig. 1, in order to protect the driving motor 20 and the compressor 30 during a vehicle collision, the driving motor 20 and the compressor 30 are disposed in a frame space enclosed by the first cross member, the second cross member, the first longitudinal member, and the second longitudinal member.

A second aspect of the present invention provides a vehicle including the front cabin structure of the vehicle according to the above technical solution. The advantages are consistent with those of the front cabin structure of the vehicle described above and will not be described herein in order to avoid unnecessary repetition.

The preferred embodiments of the present invention have been described in detail above with reference to the accompanying drawings, but the present invention is not limited thereto. Within the scope of the technical idea of the utility model, numerous simple modifications can be made to the technical solution of the utility model, including combinations of the specific features in any suitable way, and the utility model will not be further described in relation to the various possible combinations in order to avoid unnecessary repetition. Such simple modifications and combinations should be considered within the scope of the present disclosure as well.
