[0040] In the prior art, the heat pump air conditioner of electric vehicles is arranged on the crossbeam structure of the front cabin, and the two ends of the crossbeam are respectively connected to the left longitudinal beam and the right longitudinal beam. Since the heat pump air conditioner and the crossbeam structure are mostly rigidly connected, when the heat pump air conditioner is running, the vibration generated by itself will collide with the crossbeam structure rigidly to produce noise, and the vibration will be transmitted to the longitudinal beam through the crossbeam structure, and even cause the body to shake. The noise and body shaking greatly affect the driving and riding experience of customers.

[0041] Based on the above problems, the present application proposes a crossbeam structure and a car, in which a buffer bushing is installed in cooperation with the crossbeam body, and the heat pump air conditioner is installed on the shock-absorbing bushing to achieve a soft connection with the crossbeam structure. A mounting through-hole structure is provided on the crossbeam body to provide support and assembly stability for the shock-absorbing bushing. The shock-absorbing bushing is assembled with the mounting through-hole and a first assembly part and a second assembly part are formed on the shock-absorbing bushing for cooperative installation, thereby providing a soft connection with the crossbeam body.

[0042] It should be noted that the crossbeam structure proposed in the present application is suitable for installing any device that requires a flexible connection, and is not limited to installing a heat pump air conditioner.

[0043] Embodiment 1

[0044] Reference Figure 1-2 , Embodiment 1 of the present application proposes a crossbeam structure, which includes a crossbeam body 1 and a shock-absorbing bushing 4; at least one mounting through hole 2 is provided through the crossbeam body 1, and the mounting through hole 2 includes a first open end 21 and a second open end 22; a bearing portion 3 is provided in the mounting through hole 2, and one side is connected to the second open end 22, and the other side extends toward the axis of the mounting through hole 2; the shock-absorbing bushing 4 is provided in the mounting through hole 2, and a part of the shock-absorbing bushing 4 is mounted on the bearing portion 3, and the other part is provided in the mounting through hole 2 to form an assembly portion;

[0045] The assembly portion includes a first assembly portion 41 and a second assembly portion 42 . One end of the shock-absorbing bushing 4 extends out of the first opening end 21 of the mounting through hole 2 to form the first assembly portion 41 , and the other end is arranged near the second opening end 22 to form the second assembly portion 42 .

[0046] Specifically, in order to meet the stability of the installation and the rationality of the installation position, at least one or more installation through holes 2 can be provided through the crossbeam body 1 according to the installation requirements. The multiple installation through holes 2 are respectively provided at both ends of the crossbeam body 1, connected to the longitudinal beam structure by bolts and other fasteners; and are arranged at intervals in the middle of the crossbeam body 1 for installing and connecting the heat pump air conditioner.

[0047] The crossbeam body 1 is a structure with a certain strength. In the embodiment of the present application, the crossbeam structure is made of aluminum, which can ensure strength while making the parts lightweight.

[0048] In order to facilitate the installation of the mounting through hole 2 on the beam structure and to make the installation stable and firm, the mounting through hole 2 is a through hole with a certain length, which can penetrate the beam structure with a certain thickness, and form a first open end 21 and a second open end 22 on the upper and lower end faces of the beam structure respectively; wherein, the interface of the mounting through hole 2 can be a circular hole or a rectangular hole with a square cross-section, and the specific shape can be flexibly designed according to assembly needs.

[0049] The second opening end 22 is also provided with a bearing part 3, which extends into the mounting through hole 2, and can be an integral structure with the lower end surface of the beam structure; the bearing part 3 can also be an independent part in the shape of a circular ring, and the outer edge of the circular ring is fixedly arranged with the second opening end 22. Or it can be a plurality of spaced-apart carrier parts, which are spaced-apart and annularly arranged along the inner circle of the mounting through hole 2 at the second opening end 22.

[0050] The bearing portion 3 has a bearing end surface facing the first opening end 21 , and the bearing portion 3 has a certain thickness to provide structural strength for bearing the weight of the buffer bushing to prevent the buffer bushing from sliding out of the mounting through hole 2 .

[0051] The middle of the shock-absorbing bushing 4 is hollowed out for passing bolts. The outer portion of the cross-section of the shock-absorbing bushing 4 is mounted on the bearing portion 3, and the remaining inner portion is exposed to form an assembly portion in the mounting through hole 2; wherein, the upper end of the inner portion of the shock-absorbing bushing 4 is a first assembly portion 41, and the lower end is a second assembly portion 42.

[0052] The beam structure provided in the present application is provided with a mounting through hole 2 on the beam body 1, and a shock-absorbing bushing 4 is provided in the mounting through hole 2, so that the shock-absorbing bushing 4 is mounted on the bearing portion 3 extending into the mounting through hole 2, and a first assembly portion 41 is formed at one end of the shock-absorbing bushing 4, and a second assembly portion 42 is formed at the other end; the heat pump air conditioner is placed on the shock-absorbing bushing 4 and bolts are passed through the first assembly portion 41 and the second assembly portion 42, so as to realize the connection between the heat pump air conditioner and the shock-absorbing bushing 4, avoid the rigid impact of the heat pump air conditioner directly on the beam structure, prevent hard collision between metal parts, and utilize the shock-absorbing bushing 4 to absorb and disperse the vibration of the heat pump air conditioner during operation, so as to solve the problem of high noise during the operation of the heat pump air conditioner.

[0053] For further information, see Attachment Figure 2 In some embodiments, the mounting through hole 2 includes an inner hole wall, which extends from the first opening end 21 to the second opening end 22 and is located on the bearing portion 3, and the shock-absorbing bushing 4 is fixedly arranged on the inner hole wall.

[0054] Specifically, in order to improve the structural strength of the mounting through hole 2 and the degree of tightening of the shock-absorbing bushing 4 assembled in the mounting through hole 2, in the technical solution adopted by the present application, an internally closed through hole is formed in the mounting through hole 2 through the inner hole wall, and one end of the inner hole wall is also located on the bearing part 3, and can be fixed with the bearing part 3 by welding, or can be integrally formed. The shock-absorbing bushing 4 is assembled into the mounting through hole 2, and the outer side wall of the shock-absorbing bushing 4 is fixed with the inner hole wall, and the fixing method can be interference fit, gluing or welding.

[0055] For further information, see Attachment Figure 2-3In some embodiments, the shock absorbing bushing 4 includes an inner sleeve 43, an elastic layer 44 and an outer sleeve 45. The inner sleeve 43 and the outer sleeve 45 are coaxial and spaced apart. An interlayer space is formed between the outer wall of the inner sleeve 43 and the inner wall of the outer sleeve 45. The elastic layer 44 is arranged in the interlayer space and wraps the outer wall of the inner sleeve 43.

[0056] One end of the outer sleeve 45 is located on the bearing portion 3, and the other end extends to the first opening end 21, and the outer sleeve wall of the outer sleeve 45 is fixed to the inner hole wall;

[0057] One end of the inner sleeve 43 extends out of the first opening end 21 to form a first assembly portion 41 , and the other end is close to the second opening end 22 and is spaced apart from the bearing portion 3 to form a second assembly portion 42 .

[0058] Specifically, in order to realize the soft connection between the heat pump air conditioner and the beam body 1 through the shock-absorbing bushing 4, in the technical solution adopted by the present application, the inner diameter of the outer sleeve 45 is larger than the inner diameter of the inner sleeve 43, and the outer sleeve 45 is sleeved outside the inner sleeve 43 so that the shock-absorbing bushing 4 has structural strength capable of bearing pressure and load, and the interval between the inner sleeve 43 and the outer sleeve 45 forms a sandwich space, and an elastic layer 44 is arranged in the sandwich space, and the elastic layer 44 can wrap the inner sleeve 43, and the elastic layer 44 has the characteristics of elastic deformation and can absorb and disperse vibration through deformation. Among them, the elastic layer 44 can be made of rubber, nylon, the inner sleeve 43, and the outer sleeve 45 are made of carbon steel.

[0059] In order to achieve stability and firmness in assembling the shock-absorbing bushing 4 in the mounting through hole 2, the outer sleeve 45 is arranged on the bearing portion 3 and fixed to the inner hole wall by interference fit, gluing or welding.

[0060] One end of the inner sleeve 43 is a first assembly part 41, which is composed of the inner sleeve 43 and the elastic layer 44 wrapped on the outside of the inner sleeve 43. The first assembly part 41 is higher than the upper end surface of the beam body 1, so that the part to be installed is located on the first assembly part 41 and is spaced from the beam structure to prevent the part to be installed, such as a heat pump air conditioner, from directly contacting the beam body 1. When the heat pump air conditioner is running, it vibrates itself, and the vibration is transmitted to the elastic layer 44 of the shock-absorbing bushing 4 through the first assembly part 41. The elastic deformation generated by the elastic layer 44 along with the vibration absorbs and dissipates the vibration, so that mechanical energy is converted into heat energy and noise is reduced.

[0061] The other end of the inner sleeve 43 is a second assembly portion 42, which is composed of the inner sleeve 43 and an elastic layer 44 wrapped around the outer side of the inner sleeve 43. The mounting bolts are inserted from the second assembly portion 42 and exit from the first assembly portion 41 to fix and install the heat pump air conditioner. The second assembly portion 42 is spaced apart from the bearing portion 3 to prevent the mounting bolts from directly contacting the lower end surface of the beam body 1.

[0062] The shock-absorbing bushing 4 is embedded and assembled in the installation through hole 2, and the bolts are inserted into the shock-absorbing bushing 4 by utilizing the cooperation between the first assembly part 41 and the second assembly part 42, so as to avoid direct contact between the bolts and nuts used for installing the heat pump air conditioner and the crossbeam body 1, thereby achieving a soft connection to absorb the vibration of the heat pump air conditioner and reduce noise.

[0063] For further information, see Attachment Figure 2-3 In some embodiments, it also includes a mounting sleeve 5, which is disposed in the mounting through hole 2, one end of the mounting sleeve 5 is disposed on the bearing portion 3, and the other end extends out of the first opening end 21 and extends to the outside of the mounting through hole 2 to form a fixed end 51.

[0064] Specifically, in order to facilitate the installation of the shock-absorbing bushing 4 and improve the structural strength of the installation through hole 2, in the technical solution adopted by the present application, the installation sleeve 5 is arranged in the installation through hole 2, and one end is seated on the bearing portion 3. In order to improve the compactness and firmness of the shock-absorbing bushing 4 in the installation through hole 2, the shock-absorbing bushing 4 is interference-fitted with the installation sleeve 5 and arranged in the installation sleeve 5. In order to enhance the firmness of the installation sleeve 5, the other end of the installation sleeve 5 extends out of the first open end 21 and extends outward to form a fixed end 51, and the lower end surface of the installation end is in contact with and fixed to the upper end surface of the beam body 1, and the fixing method can be welding or gluing.

[0065] For further information, see Attachment Figure 2-3 In some embodiments, the inner side wall of the mounting sleeve 5 is the inner hole wall, and the shock absorbing bushing 4 is interference fitted in the mounting sleeve 5. Or the outer side wall of the mounting sleeve 5 is fixedly arranged with the inner hole wall, and the shock absorbing bushing 4 is interference fitted in the mounting sleeve 5.

[0066] Specifically, in order to realize the firm and stable assembly of the shock-absorbing bushing 4 in the installation through hole 2, in the technical solution adopted by the present application, the inner side wall of the installation sleeve 5 and the inner hole wall are integrated, and the shock-absorbing bushing 4 is interference-fitted in the installation sleeve 5. Alternatively, the installation through hole 2 itself has an inner hole wall to form an internally closed through hole, so that the outer side wall of the installation sleeve 5 and the inner hole wall are fixedly arranged to avoid relative displacement, and the fixing setting method is interference, welding or gluing, and then the shock-absorbing bushing 4 is interference-fitted in the installation sleeve 5. The interference setting method is pressing in by a press.

[0067] The shock-absorbing bushings 4 can be separated from the mounting sleeves 5 by using specific mechanical tools, so that the shock-absorbing bushings 4 can be replaced.

[0068] Since the elastic layer 44 has a certain hardness, in order to prevent the shock-absorbing bushing 4 from being relatively displaced with the inner hole wall or even falling out of the mounting through hole 2 due to vibration before the elastic layer 44 is deformed by vibration, an installation sleeve 5 is added in the mounting through hole 2 to make the installation of the outer sleeve 45 of the shock-absorbing bushing 4 and the inner hole wall more compact and firm.

[0069] For further information, see Attachment Figure 2-3 In some embodiments, the elastic layer 44 is provided with a shock absorbing groove 441 near the first opening end 21 and the second opening end 22.

[0070] Specifically, in order to achieve better shock absorption and noise reduction of the shock-absorbing bushing 4, in the technical solution adopted in the present application, shock-absorbing grooves 441 are respectively arranged at the upper and lower ends of the elastic layer 44. The shock-absorbing grooves 441 are concave annular grooves arranged on the outer peripheral side of the elastic layer 44. The concave part is easy for the elastic layer 44 to deform, thereby absorbing vibration.

There are at least two crossbeam supports 6 arranged at the left and right ends of the crossbeam body 1, and respectively connected to the left longitudinal beam and the right longitudinal beam of the front cabin.

[0074] The crossbeam support 6 is detachably connected to the crossbeam body 1 through a first connection member 61, and is detachably connected to the longitudinal beam through a second connection member 62. The connection method may be bolt, nut connection, clamping or plugging.

[0075] For further information, see Attachment Figure 4-7 In some embodiments, the first connecting member 61 includes a first end face 611 and a second end face 612 which are spaced apart, and a connecting hole 613 which passes through the first end face 611 and the second end face 612, wherein a mounting portion 614 is disposed in the connecting hole 613, wherein one side of the mounting portion is connected to the first end face 611, and the other side extends toward the axis of the connecting hole 613;

[0076] The second connecting member 62 includes a first end plate 621 disposed along the length direction of the beam body 1 and a second end plate 622 disposed at an angle to the first end plate 621 .

[0077] Specifically, in order to achieve the connection between one end of the beam support 6 and the beam body 1 and the other end of the beam support 6 and the longitudinal beam, in the technical solution adopted in the present application, the beam support 6 and the first and second connecting members 62 arranged at both ends are all made of certain structural metal materials. In the embodiment of the present application, aluminum material is selected, which can both provide strength and reduce weight.

[0078] The first connecting member 61 is a structural member with a certain thickness. The first end face 611 is used to contact the lower end face of the beam body 1, and a through connecting hole 613 is opened in the first connecting member 61. The opening position of the connecting hole 613 corresponds to the position of the mounting through hole 2 at both ends of the beam body 1. The mounting portion 614 is integrally arranged with the first end face 611, so that the hole diameter on the first end face 611 is smaller than the hole diameter on the second end face 612. A threaded sleeve is installed in the connecting hole 613, and one end of the threaded sleeve is in contact with the mounting portion 614.

[0079] The beam support 6 is placed at the lower end of the beam body 1, so that the first connecting member 61 contacts the lower end of the beam body 1, and the installation through hole 2 corresponds to the connection hole 613, and the bolt enters through the installation through hole 2 and passes through the connection hole 613 to achieve the installation of the beam support 6 and the beam body 1.

[0080] The second connecting member 62 includes a first end plate 621 and a second end plate 622. The first end plate 621 and the second end plate 622 have an included angle, so that the second connecting member 62 forms a "Y"-shaped member, and the angle range is 30°-120°, preferably 90°. The first end plate 621 is installed with the transverse end surface of the longitudinal beam, and the second end plate 622 is installed with the vertical end surface of the longitudinal beam. The first end plate 621 and the second end plate 622 are both provided with a plurality of mounting holes, and bolts are passed through the mounting holes and tightened to achieve the installation of the second connecting member 62 and the longitudinal beam.
