Description

Technical Field

[0001] The utility model relates to the field of compressor installation equipment, in particular to a compressor base structure and a compressor bracket assembly having the base structure. Background Art

[0002] Under the dual pressure of energy and environmental protection, new energy vehicles have become the mainstream of industry development. During the operation of the vehicle air-conditioning system, due to the lack of engine background noise, coupled with the high speed operation of the electric compressor caused by the vehicle heat pump and super fast charging, the NVH problem of the electric compressor has become the main problem complained by current customers, and it is urgently needed to avoid and optimize it from the design dimension.

[0003] There are generally two ways to arrange the electric compressor of new energy vehicles. One is to connect the electric compressor to the front motor or engine through a rigid bracket, and achieve shock absorption of the electric compressor through a shared dynamic total suspension. The other is to connect the electric compressor to the front cabin chassis or body parts through a shock-absorbing bracket, and achieve attenuation of the vibration of the electric compressor body through the built-in shock-absorbing structure (rubber bushing or spring structure).

[0004] The latter method generally has two specific ways to arrange the electric compressor shock absorber bracket. One is fixed on the subframe; the other is fixed on the longitudinal beam through a separately designed compressor bracket crossbeam.

[0005] The compressor bracket crossbeam is an important part for fixing the shock-absorbing bracket of the electric compressor. It has a great influence on the NVH performance of the electric compressor, and its design needs to be paid attention to.

[0006] In addition, as automobile production and speed grow rapidly, the requirements for safety collisions become increasingly stringent. Each model selects a suitable crossbeam structure and fixing method based on the positioning of the entire vehicle, taking into account NVH performance, collision safety, cost, and weight target factors.

[0007] The dynamic stiffness of the compressor shock absorber bracket installation point of the compressor bracket crossbeam is generally required to be greater than 1500N / m or 2000N / m. This method can curb the noise of the electric compressor during air-conditioning operation to a certain extent. However, under special circumstances of crossbeam load and arrangement, the required dynamic stiffness cannot be increased by designing the crossbeam structure itself, and it is necessary to strengthen the constraints of the bracket crossbeam and longitudinal beam.

[0008] However, during a safe collision, the normal collapse of the longitudinal beam must be ensured, and the over-constraint in the deformation path of the longitudinal beam must be weakened; therefore, it is also required that the constraint between the bracket crossbeam and the longitudinal beam cannot affect the normal collapse of the longitudinal beam.

[0009] After searching, the existing patent 201420853536.3 - A refrigeration compressor and water pump mounting combined bracket for electric trucks does not clearly provide technical inspiration for solving the above technical problems.

[0010] Therefore, in order to improve or solve at least one of the above technical problems, it is necessary to optimize the connection method between the existing support cross beam and the longitudinal beam. Utility Model Content

[0040] The utility model facilitates the assembly of the rear support beam 11 on the left and right longitudinal beams of the automobile by setting the base structure 1-1. In the utility model, the first function of the base structure 1-1 is to act as a bridging member, mainly to facilitate the installation and fixation of the support beam 11 on the longitudinal beam.

[0041] At the same time, the utility model can greatly ensure the stability of the base and beam structure installed on the longitudinal beam by fitting the longitudinal support plate 1 and the transverse support plate 2 on the longitudinal beam, and then use the longitudinal beam mounting part, thereby ensuring the dynamic stiffness of the compressor bracket at the bracket beam mounting point.

[0042] The base structure 1 - 1 disclosed in the utility model is mainly used for installing and assembling the support cross beam 11 on the longitudinal beam.

[0043] Specifically, the base structure 1-1 disclosed in the utility model mainly includes a base body, which is the main structure of the base structure 1-1, and a longitudinal beam mounting part and a cross beam mounting part are provided on the base body; the longitudinal beam mounting part is used for installing and fixing the base structure 1-1 on the longitudinal beam, and the cross beam mounting part is used for installing and connecting the support cross beam 11 and the base structure 1-1.

[0044] In the present invention, the seat body includes a seat body body, which is the main structure of the seat body, and the seat body body includes a longitudinal support plate 1; an end surface bonding plate 3 is provided on the longitudinal support plate 1; a transverse support plate 2 is provided on the side of the longitudinal support plate 1; the longitudinal beam mounting portion includes an upper mounting portion and a lower mounting portion; the longitudinal support plate 1 plays a longitudinal elevation role, and the end surface bonding plate 3 is used for the subsequent connection of the bracket cross beam 11. In the present invention, the longitudinal support plate 1 and the transverse support plate 2 are required to be basically arranged perpendicular to each other; when in use, the longitudinal support plate 1 can be bonded to the inner side surface of the corresponding longitudinal beam, and the transverse support plate 2 is arranged on the upper end surface of the longitudinal beam. Such an arrangement makes the seat body equivalent to being hung on the corresponding longitudinal beam, and the subsequent longitudinal beam mounting plate is equivalent to setting a reinforcement block on the longitudinal beam. The subsequent bracket cross beam 11 is connected to the longitudinal beam through the base structure 1-1. Because of the existence of the base structure 1-1, the dynamic stiffness of the bracket cross beam 11 and the compressor bracket mounting point can be significantly improved; to a certain extent, the vibration of the electric compressor 10 body is effectively isolated.

[0045] In actual arrangement, the end surface bonding plate 3 is arranged at the end of the longitudinal support plate 1, and the transverse support plate 2 is arranged in the middle area of ​​the longitudinal support plate 1; the longitudinal support plate 1 and the transverse support plate 2 form an inverted L-shaped structure, which is convenient for subsequent hanging on the longitudinal beam.

[0046] At the same time, the lower mounting portion in the utility model includes a longitudinal beam lower mounting hole 111 arranged on the longitudinal support plate 1; the setting of the longitudinal beam lower mounting hole 111 facilitates the subsequent passing of bolts through the corresponding longitudinal beam lower mounting hole 111, so that the longitudinal support plate 1 is restrained on the side of the longitudinal beam. In actual design, two or more longitudinal beam lower mounting holes 111 can be set, so that the longitudinal support plate 1 has multiple mounting points with the longitudinal beam, and the stability of the installation of the longitudinal support plate 1 and the longitudinal beam is better guaranteed.

[0047] In addition, the upper mounting portion in the utility model includes a longitudinal beam mounting hole 21 arranged on the transverse support plate 2; the longitudinal beam mounting hole 21 is mainly arranged on the transverse support plate 2, and subsequently bolts are used to pass through the transverse support plate 2 and connect with the upper end surface of the longitudinal beam, thereby realizing the connection and fixation between the transverse support plate 2 and the longitudinal beam.

[0048] In addition, the beam mounting portion in the present invention includes a beam mounting hole 31 arranged on the end face bonding plate 3; the setting of the transverse mounting hole is mainly for realizing the bonding connection between the bracket beam 11 and the end face bonding plate 3; at least two beam mounting holes 31 are provided on the end face bonding plate 3, and subsequently the connection between the bracket beam 11 and the end face bonding plate 3 is realized by passing bolts through the bracket beam 11 and the end face bonding plate 3.

[0049] Furthermore, in the utility model, the mounting hole 111 under the longitudinal beam is a U-shaped hole; the side of the mounting hole 111 under the longitudinal beam is connected to the outer side of the longitudinal support plate 1; based on such a setting, while realizing the connection between the longitudinal support plate 1 and the longitudinal beam, it is also convenient to separate the longitudinal support plate 1 from the corresponding bolts during subsequent use, thereby reducing the setting of the longitudinal support plate 1 and affecting the normal collapse energy absorption of the longitudinal beam.

[0050] Furthermore, in the utility model, an induction groove 5 is provided on the longitudinal support plate 1; the essential function of the setting of the induction groove 5 in the utility model is to reduce the overall structural strength of the longitudinal support plate 1, so that the longitudinal support plate 1 can be broken more easily after a subsequent collision, thereby avoiding the increased difficulty of longitudinal beam collapse caused by the setting of the base structure 1-1.

[0051] Furthermore, in the utility model, a material reduction notch 6 is provided on the longitudinal support plate 1; the material reduction notch 6 and the induction groove 5 are distributed on opposite sides of the longitudinal support plate 1; one function of the material reduction notch 6 is to reduce the overall weight of the base structure 1-1, and the other function is to reduce the structural strength of the longitudinal support plate 1. The material reduction notch 6 and the induction groove 5 are relatively distributed on both sides of the longitudinal support plate 1. Such an arrangement enables the base structure 1-1 to constrain the side of the longitudinal beam. After a head-on collision, the longitudinal beam can cut off the longitudinal support plate 1 through the weak point of the base induction groove 5, thereby releasing the deformation constraint of the base on the longitudinal beam, ensuring the normal collapse of the longitudinal beam, and ensuring the safety of the occupants in the cabin.

[0052] Furthermore, in the present invention, a beam positioning hole 8 is provided on the end surface bonding plate 3; the beam positioning hole 8 here mainly cooperates with the protrusion (positioning pin) on the bracket beam 11, so as to ensure the accuracy of the position of the bracket beam 11 when it is placed on the base.

[0053] Furthermore, in the utility model, a threading end plate 7 is provided on the end face bonding plate 3; in the utility model, a threading hole is provided on the threading end plate 7, which serves as a lead plate for subsequent use, and is convenient for the subsequent limiting of the threading wiring harness, which is essentially used to provide an installation point for the wiring harness.

[0054] Furthermore, in the utility model, the seat body also includes a side connecting plate 4; a side connecting plate 4 is respectively provided on both sides of the seat body; each of the side connecting plates 4 is simultaneously perpendicularly distributed with the longitudinal support plate 1, the transverse support plate 2 and the end face bonding plate 3; the end face bonding plate 3 and the transverse support plate 2 are parallelly and offsetly distributed; the side connecting plate 4 acts as a reinforcement and a connecting member, mainly to realize the side connection of the longitudinal support plate 1, the end face bonding and the transverse support plate 2, so as to ensure the integrity of the base.

[0055] In addition, in the utility model, the longitudinal support plate 1 includes an upper support plate 12 and a lower support plate 11; the end face bonding plate 3 is connected to the transverse support plate 2 through the upper support plate 12; the lower support plate 11 is connected to the transverse support plate 2 through the side connecting plate 4; the end face bonding plate 3, the upper support plate 12, the transverse support plate 2 and the side of the lower support plate 11 are all connected through the side connecting plate 4; in actual arrangement, the upper support plate 12 and the lower support plate 11 are staggered in distribution from the attached view, and the end face bonding plate 3 is connected to the transverse support plate 2 through the upper support plate 12; the lower support plate 11 is connected to the transverse support plate 2 through the side connecting plate 4. Based on such a setting, the seat body has a corresponding hollow position, which plays a good avoidance role; it is convenient for the subsequent bolt threading and installation.

[0056] A support assembly for a compressor 10 includes a support crossbeam 11, wherein both ends of the support crossbeam 11 are connected to the longitudinal beam of the vehicle body through a base structure 1-1 for the compressor 10; the two ends of the support crossbeam 11 disclosed in the utility model are connected to the longitudinal beam of the vehicle body through the base structure 1-1, and such an arrangement facilitates the mutual connection between the crossbeam support and the longitudinal beam. At the same time, in the utility model, the base structure 1-1 is arranged to avoid the problem that the dynamic stiffness of the mounting point of the shock-absorbing support 9 of the compressor 10 is too low, and the vibration of the electric compressor 10 body cannot be effectively isolated, and the NVH problem of the electric compressor 10 caused by turning on the air conditioner of the new energy vehicle model can be solved; in addition, through the arrangement of the induction groove 5 and the notch, it can also avoid the arrangement of the base structure 1-1 affecting the normal collision and collapse of the longitudinal beam.

[0057] Furthermore, in the utility model, the bracket beam 11 is connected to the compressor 10 through the shock-absorbing bracket 9; based on such a setting, the problem of low dynamic stiffness of the installation point of the shock-absorbing bracket 9 of the compressor 10, which cannot effectively isolate the vibration of the electric compressor 10 body, can be avoided.

[0058] specific:

[0059] The utility model discloses a support assembly for a compressor 10, mainly comprising a support crossbeam 11, wherein both ends of the support crossbeam 11 are respectively connected to the longitudinal beam of the vehicle body through a base structure 1-1 for the compressor 10; the support crossbeam 11 of a conventional compressor 10 is generally directly fixed on the left and right longitudinal beams, but when the dynamic stiffness of the shock-absorbing support 9 of the compressor 10 is insufficient when installing, the noise problem during the operation of the compressor 10 needs to be improved.

[0060] The utility model can effectively increase the dynamic stiffness of the installation point of the shock-absorbing bracket 9 of the compressor 10 through the setting of the base structure 1-1, thereby achieving effective vibration isolation of the electric compressor 10 body, and then solving the NVH problem of the electric compressor 10 caused by turning on the air conditioner in new energy vehicles.

[0061] The core of the utility model is to provide a base structure 1-1 of a bracket crossbeam 11 and a longitudinal beam, which increases the dynamic stiffness of the compressor 10 shock-absorbing bracket 9 installation point in the Z direction from less than 600N / mm to nearly 1500N / mm, that is, the NVH performance of the electric compressor 10 is optimized to a great extent, and the over-constraint in the deformation path of the longitudinal beam is weakened by designing and optimizing structures such as the induction groove 5 and the U-shaped hole, ensuring that the longitudinal beam collapses after a head-on collision and cuts off the base structure 1-1, thereby ensuring the safety of the passenger compartment.

[0062] like Figure 1 As shown, the novel compressor 10 support beam 11 base structure 1-1 provided by the utility model is divided into two left and right monomers, both of which are formed by one-piece die-casting and then machined, and the material is A380 aluminum.

[0063] Each base structure 1-1 includes a base body, which has multiple mounting surfaces, namely an upper longitudinal beam mounting surface, a side longitudinal beam mounting surface and a cross beam mounting surface. The upper longitudinal beam mounting surface is provided with two longitudinal beam upper mounting holes 21; the side longitudinal beam mounting surface and the side longitudinal beam mounting surface have U-shaped longitudinal lower mounting holes; four bolts are subsequently used to fix the base body to the corresponding longitudinal beam, and the compressor 10 support cross beam 11 is overlapped on the end face bonding plate 3, and then the connection between the end face bonding plate 3 and the support cross beam 11 is realized by bolts passing through the cross beam mounting hole 31.

[0064] The utility model increases the dynamic stiffness of the mounting point of the shock-absorbing bracket 9 of the compressor 10 to a certain extent and optimizes the NVH performance of the electric compressor 10 by fitting the upper longitudinal beam mounting surface and the side longitudinal beam mounting surface of the seat body on the longitudinal beam.

[0065] At the same time, the restraint of the base on the side of the longitudinal beam is weakened by the opening design of the induction groove 5, the notch and the U-shaped lower mounting hole. After a head-on collision, the longitudinal beam can be cut off from the base through the weak point of the induction groove 5 of the base structure 1-1, thereby releasing the deformation restraint of the base on the longitudinal beam, ensuring the normal collapse of the longitudinal beam and protecting the safety of the occupants in the passenger compartment.

[0066] This structure is suitable for new energy vehicles in which the electric compressor 10 is installed on the longitudinal beam through the compressor 10 shock-absorbing bracket 9 and the cross beam.

[0067] Obviously, the specific implementation of the present invention is not limited by the above-mentioned methods. As long as various non-substantial improvements are made using the method concept and technical solution of the present invention, they are all within the protection scope of the present invention.
