[0001] This application relates to the field of vehicle design and manufacturing technology, and in particular to a crossbeam assembly and a vehicle equipped with the crossbeam assembly. Background Technology

[0002] With the development of automotive industrialization and intelligentization, the pressure of vehicle weight and cost is increasing, while the corresponding demand for NVH attributes is also rising. NVH is an abbreviation for Noise, Vibration, and Harshness, referring to all undesirable sounds and vibrations that passengers can experience inside the vehicle. NVH performance is one of the important indicators for measuring automotive comfort and directly affects the quality of the driving and riding experience.

[0003] In existing technology, the dashboard crossbeam system generally includes a crossbeam and a steering column and air conditioning equipment mounted on the crossbeam via brackets. These brackets are typically attached to the crossbeam by either mounting or welding. However, both mounting and welding methods require significant space within the vehicle body, which is inconvenient for installing surrounding components. Utility Model Content

[0034] As can be seen from the above technical solutions, in the crossbeam assembly and vehicle provided by this application, a crossbeam is formed by the first crossbeam connecting unit and the second crossbeam connecting unit, which are disconnected in the left-right direction of the vehicle.

This allows the target device to be installed between the first crossbeam connecting unit and the second crossbeam connecting unit, i.e., the target device is located at the disconnected position of the crossbeam. Compared with the solution where the target device is attached to a crossbeam with an integral structure, the crossbeam assembly provided by this application, because the first crossbeam connecting unit and the second crossbeam connecting unit form a disconnected crossbeam structure, lacks a portion of the crossbeam section compared to the integral crossbeam structure, thus helping to reduce the vehicle's weight. Furthermore, in the crossbeam assembly and vehicle provided in this application, since the target device is embedded in the accommodating space between the first mounting part of the first crossbeam connecting unit and the second mounting part of the second crossbeam connecting unit, that is, the first mounting part and the second mounting part can enable the first crossbeam connecting unit, the target device, and the second crossbeam connecting unit to be connected sequentially along the left and right direction of the vehicle, the target device and its connecting structure occupy less space in the vehicle body, especially in the vehicle height direction, which is beneficial to the installation and arrangement of the target device and its surrounding components.

[0063] This application provides a crossbeam assembly that can span between the left and right sides of the vehicle body, and a vehicle equipped with the crossbeam assembly. By installing the target device in the crossbeam with a disconnected structure, it can save a significant amount of space in the Z direction. Furthermore, the modal properties of the target device and the entire vehicle can be improved through the mating surface, the hollow box and its reinforcing structure.

[0064] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this application.

[0065] First Specific Embodiment

[0066] A first embodiment of this application provides a crossbeam assembly for mounting a target device between the left and right sides of the vehicle body. See also... Figures 1 to 12 The following example illustrates how the target device, including the air conditioning unit 3 and the crossbeam assembly, is connected at both ends to the A-pillar on the left side of the vehicle body (hereinafter referred to as the left A-pillar or left A-pillar) and the A-pillar on the right side of the vehicle body (hereinafter referred to as the right A-pillar or right A-pillar).

[0067] Please see Figure 1 as well as Figures 5 to 8 The beam assembly mainly includes a first beam connecting unit 11 and a second beam connecting unit 12. Wherein: one end of the first crossbeam connecting unit 11 is provided with a first connecting part 101 for connecting with the left A-pillar of the vehicle body, and the other end is provided with a first mounting part 21 closer to the right A-pillar of the vehicle body than the first connecting part 101. The first mounting part 21 includes a first connecting surface for connecting with the first crossbeam connecting unit 11, and a first mounting surface 21' for connecting with the first side 301 of the air conditioning equipment 3; one end of the second crossbeam connecting unit 12 is provided with a second connecting part 102 for connecting with the right A-pillar of the vehicle body, and the other end is provided with a second mounting part 22 closer to the left A-pillar of the vehicle body than the second connecting part 102. The second mounting part 22 includes a second connecting surface for connecting with the second crossbeam connecting unit 12, and a second mounting surface 22' for connecting with the second side 302 of the air conditioning equipment 3; in the left-right direction Y of the vehicle, the first mounting surface 21' and the second mounting surface 22' are arranged opposite to each other to form an accommodating space for installing the air conditioning equipment 3, that is, the interval distance a between the first mounting surface 21' and the second mounting surface 22' is greater than zero and is adapted to the left and right width dimensions of the air conditioning equipment 3.

[0068] As can be seen, in the crossbeam assembly provided in the first specific embodiment of this application, a crossbeam that is disconnected in the left-right direction Y of the vehicle is formed by the first crossbeam connecting unit 11 and the second crossbeam connecting unit 12. A space for installing the air conditioning device 3 is formed by the first mounting surface 21' of the oppositely arranged first mounting part 21 and the second mounting surface 22' of the second mounting part 22. The air conditioning device 3 is connected to the air conditioning device 3 through these first mounting surfaces 21' and 22', allowing it to be embedded between the first crossbeam connecting unit 11 and the second crossbeam connecting unit 12, i.e., the air conditioning device 3 is located at the disconnected position of the crossbeam. Compared to the scheme where the air conditioning device is mounted on a crossbeam with an integral structure, when installing the air conditioning device 3 using the crossbeam assembly provided in this application, since the first crossbeam connecting unit 11 and the second crossbeam connecting unit 12 form a disconnected crossbeam, it lacks a portion of the crossbeam section compared to the integral crossbeam, thus helping to reduce the vehicle's weight. Furthermore, in the crossbeam assembly provided in this application, since the air conditioning unit 3 is embedded in the accommodating space between the first mounting portion 21 of the first crossbeam connecting unit 11 and the second mounting portion 22 of the second crossbeam connecting unit 12, the first mounting portion 21 and the second mounting portion 22 can enable the first crossbeam connecting unit 11, the air conditioning unit 3, and the second crossbeam connecting unit 12 to be sequentially connected along the left-right direction Y of the vehicle (see [reference]). Figures 5 to 8 This design minimizes the space occupied by the air conditioning unit 3 and its connecting structure within the vehicle body, especially in the Z-direction of vehicle height, which facilitates the installation and arrangement of the air conditioning unit 3 and its surrounding components (such as air ducts and air vents).

[0069] For specific implementation details, please refer to [link / reference]. Figures 5 to 8 When the air conditioning unit 3 is installed in the crossbeam assembly, the first mounting part 21 of the first crossbeam connecting unit 11 and the second mounting part 22 of the second crossbeam connecting unit 12 are located on both sides of the air conditioning unit 3, and are respectively connected to the first side 301 and the second side 302 of the air conditioning unit 3. Thus, the first mounting surface 21' of the first mounting part 21 and the first side 301 of the air conditioning unit 3, as well as the second mounting surface 22' of the second mounting part 22 and the second side 302 of the air conditioning unit 3, are in surface contact. Their connection positions can achieve stable installation of the air conditioning unit 3 through any method such as welding, snap-fitting, or fastener connection. This not only facilitates assembly operations but also helps ensure the positioning effect of the air conditioning unit 3 and optimizes the modal properties of the air conditioning unit 3 at the installation position, thereby helping to optimize the modal properties of the entire vehicle. It should be noted that the modal properties mentioned in this application refer to the inherent vibration characteristics exhibited by a structural system (such as the body, chassis, air conditioning unit, and the entire vehicle) when subjected to dynamic excitation.

[0070] Please see Figure 3 and Figure 4In some embodiments, the first mounting part 21 includes a first hollow box, with its two sides being a first connecting surface for connecting with the first crossbeam connecting unit 11 and a first mounting surface 21' for connecting with the first side 301 of the air conditioning unit 3, as described above; and / or, the second mounting part 22 includes a second hollow box, with its two sides being a second connecting surface for connecting with the second crossbeam connecting unit 12 and a second mounting surface 22' for connecting with the second side 302 of the air conditioning unit 3, as described above. In specific implementations, the first mounting surface 21' and the second mounting surface 22' can be kept substantially parallel and located on the left and right sides of the air conditioning unit 3, respectively, thereby facilitating the installation of the air conditioning unit 3. However, this is not the only option. In other implementations, the plane containing the first mounting surface 21' and the plane containing the second mounting surface 22' can be arranged at a certain angle according to the specific shape and structure of the air conditioning device 3, as long as a space for installing the air conditioning device 3 can be formed between the first mounting surface 21' and the second mounting surface 22', and the first mounting surface 21' and the second mounting surface 22' can be fitted and connected to the left and right sides of the air conditioning device 3 respectively. It should be noted that since both the first mounting part 21 and the second mounting part 22 are hollow box structures, this structure can, to a certain extent, absorb vibration and reduce noise transmission, thereby improving the NVH properties of the crossbeam assembly and the vehicle body. Furthermore, sound-absorbing cotton can be added to the hollow box structure to further enhance the vibration damping and absorption effect at this location.

[0071] In some embodiments, please refer to Figure 12 The first mounting portion 21 and the first side surface 301 of the air conditioning unit 3 are fixedly connected by a first fastener 201. Specifically, the first mounting surface 21' of the first mounting portion 21 can be fitted against the first side surface 301 of the air conditioning unit 3. The first fastener 201 passes through the first connecting surface and the first mounting surface 21' of the first mounting portion 21, with one end of the first fastener 201 located outside the first connecting surface and engaged with it for limitation, and the other end of the first fastener 201 fixedly connected to the first side surface 301 of the air conditioning unit 3. Similarly, the second mounting portion 22 and the second side surface 302 of the air conditioning unit 3 can be fixedly connected by a second fastener 202. Specifically, the second mounting surface 22' of the second mounting portion 22 can be fitted against the second side surface 302 of the air conditioning unit 3. The second fastener 202 passes through the second connecting surface and the second mounting surface 22' of the second mounting portion 22, with one end of the second fastener 202 located outside the second connecting surface and engaged with it for limitation, and the other end of the second fastener 202 fixedly connected to the second side surface 302 of the air conditioning unit 3.

[0072] Further, please see Figure 2 and Figure 12In some embodiments: a groove 24 recessed into the first hollow box is provided in the first connecting surface of the first mounting part 21 near the first crossbeam connecting unit 11, at the position for mounting the first fastener 201, and the limiting end of the first fastener 201 is located in the groove 24 of the first connecting surface; and / or, a groove 24 recessed into the first hollow box is provided in the first assembly surface 21' of the first mounting part 21 near the air conditioning device 3, and the first fastener 201 is connected to the air conditioning device 3 after passing through the groove 24 in the first connecting surface and / or the groove 24 in the first assembly surface 21'. Similarly, in the second connecting surface of the second mounting part 22 near the second crossbeam connecting unit 12, a groove 24 recessed into the second hollow box is provided at the position for installing the second fastener 202, and the limiting end of the second fastener 202 is located in the groove 24 of the second connecting surface; and / or, in the second assembly surface 22' of the second mounting part 22 near the air conditioning unit 3, a groove 24 recessed into the second hollow box is provided, and the second fastener 202 passes through the groove 24 of the second connecting surface and / or the groove 24 in the second assembly surface 22' and is connected to the air conditioning unit 3. Through the above-mentioned groove 24 combined with the hollow box structure design, a structure with improved structural deformation resistance and enhanced connection stability can be formed on the first mounting part 21 and the second mounting part 22, thereby effectively improving the self-strength of the first mounting part 21 and the second mounting part 22, and effectively improving the vertical strength between the first mounting part 21 and the air conditioning unit 3 and between the second mounting part 22 and the air conditioning unit 3 at the connection position, which is beneficial to improving the NVH properties of the crossbeam assembly. It's important to note that NVH is an abbreviation for Noise, Vibration, and Harshness, referring to all undesirable sounds and vibrations that passengers may experience inside a vehicle. NVH performance is a crucial indicator of automotive comfort and directly impacts the quality of the driving and riding experience.

[0073] In a specific implementation, the groove 24 can be configured as a recessed structure similar to a trumpet shape, that is, the shape of the opening cross section of the groove 24 gradually decreases along its depth direction, and the opening area of ​​the groove 24 on the surface of the first mounting part 21 and the second mounting part 22 is greater than the bottom area of ​​the groove 24. In some embodiments, the bottom of the groove 24 located on the first connecting surface is close to or fits against the panel where the first assembly surface 21' is located, and the bottom of the groove 24 located on the first assembly surface 21' is close to or fits against the panel where the first connecting surface is located. Furthermore, the plurality of grooves 24 located on the first connecting surface and the plurality of grooves 24 located on the first assembly surface 21' correspond one-to-one, and the bottom surface of each groove 24 is provided with mounting holes for installing the first fastener 201 (e.g., screws or bolts). Similarly, the bottom of the groove 24 located on the second connecting surface is close to or fits against the panel where the second assembly surface 22' is located, and the bottom of the groove 24 located on the second assembly surface 22' is close to or fits against the panel where the second connecting surface is located. Furthermore, the plurality of grooves 24 located on the second connecting surface and the plurality of grooves 24 located on the second assembly surface 22' correspond one-to-one, and the bottom surface of each groove 24 is provided with mounting holes for installing the second fastener 202 (e.g., screws or bolts).

[0074] In specific implementation, multiple connection points are provided on the left and right sides of the air conditioning unit 3. Correspondingly, the first mounting part 21 is provided with multiple first connection points, and the second mounting part 22 is provided with multiple second connection points. For example, the first mounting part 21 is provided with multiple (e.g., three, four, or six) first connection points, which are located within the groove 24. At least some of the first connection points are arranged in a ring matrix around the center of the first mounting part 21, or symmetrically arranged with the center line of the first mounting part 21 as the axis of symmetry, to ensure a stable connection between the first crossbeam connecting unit 11 and the air conditioning unit 3. Similarly, the second mounting part 22 is provided with multiple (e.g., four) second connection points, which are located within the groove 24. At least some of the second connection points are arranged in a ring matrix around the center of the second mounting part 22, or symmetrically arranged with the center line of the second mounting part 22 as the axis of symmetry, to ensure a stable connection between the second crossbeam connecting unit 12 and the air conditioning unit 3. However, this is not the only option. In other embodiments, other numbers of connection points can be provided, such as five, nine, or other numbers of connection points on the left and right sides of the air conditioning unit 3. The NVH properties of the beam assembly can be effectively improved through the aforementioned multiple connection points and reinforced structural design.

[0075] Further, please see Figure 1 and Figure 2In some embodiments, the first connecting surface of the first mounting portion 21 is provided with a first reinforcing rib 23; and / or, the first assembly surface 21' of the first mounting portion 21 is provided with a first reinforcing rib 23; and / or, the second connecting surface of the second mounting portion 22 is provided with a first reinforcing rib 23; and / or, the second assembly surface 22' of the second mounting portion 22 is provided with a first reinforcing rib 23. In specific implementations, the first reinforcing rib 23 can be formed by multiple parallel strip grooves or strip protrusions, or by multiple strip grooves or strip protrusions arranged in a mesh-like pattern, thereby improving the structural strength of the first mounting portion 21 and the second mounting portion 22. However, this is not limited to this; in other embodiments, the first reinforcing rib 23 can also be provided by thickening or protrusion, etc. This application does not specifically limit the formation method and specific shape of the reinforcing rib.

[0076] Please see Figure 1 , Figure 5 and Figure 8 In some embodiments, the aforementioned crossbeam assembly is further provided with a third connecting part 5 for connecting to the central channel. The third connecting part 5 includes two parallel first supports 51, which are respectively connected to the first crossbeam connecting unit 11 and the second crossbeam connecting unit 12, and are respectively connected to both sides of the central channel or to the top of the central channel. Furthermore, a second support 52, capable of connecting to the air conditioning unit 3, is transversely arranged between the two parallel first supports 51. Thus, the third connecting part 5 further ensures the stable installation of the air conditioning unit 3 and its corresponding crossbeam assembly.

[0077] In a specific implementation, the air conditioning unit 3 includes a first side 301 and a second side 302 positioned opposite each other.

See [link to details]. Figure 6 The second side 302 of the air conditioning unit 3 is provided with a second connection area, which is used to adapt and connect with the second mounting part 22 in the beam assembly described above. For details, please refer to [link / reference needed]. Figure 5 .

[0079] In specific implementation, multiple (e.g., three, four, or six) first protrusions 30 are respectively provided on the left and right sides of the air conditioning unit 3. At least some of the first protrusions 30 are arranged in a ring matrix around the center of the first connecting area, or arranged symmetrically in two groups, to ensure a stable connection between the first mounting part 21 and the air conditioning unit 3. Similarly, at least some of the first protrusions 30 are arranged in a ring matrix around the center of the second connecting area, or arranged symmetrically in two groups, to ensure a stable connection between the second mounting part 22 and the air conditioning unit 3. However, it is not limited to this. In other embodiments, other numbers of first protrusions 30 can also be provided, such as five or nine or other numbers of first protrusions 30 on the left and right sides of the air conditioning unit 3.

[0081] Second specific embodiment

[0082] Please see Figure 13The second embodiment of this application provides a crossbeam assembly, which differs from the first embodiment in that: the target device installed in the disconnected position of the crossbeam assembly includes a steering column 4, that is, the accommodating space formed by the disconnection between the first crossbeam connecting unit 11 and the second crossbeam connecting unit 12 is used to install the steering column 4. The steering column 4 includes a column body 41 and a fourth connecting portion 42, with the column body 41 located below and connected to the fourth connecting portion 42 to form an integral structure of the steering column 4.

[0083] Please see Figure 14 In the second specific embodiment of this application, in the crossbeam assembly, the side of the first mounting part 21 that is close to and connected to the first crossbeam connecting unit 11 is a first connecting surface. In this first connecting surface, a groove 24 recessed into the first hollow box is provided at the position for connecting with the fourth connecting part 42 in the steering column 4 by a first fastener. Specifically, the circumferential sidewall of the groove 24 is located between the first connecting surface and the first assembly surface 21' of the first mounting part 21, with one end connected to the first connecting surface and the other end connected to the bottom panel of the groove 24; the bottom panel of the groove 24 is close to or fits against the first assembly surface 21', and the corresponding positions of the bottom panel of the groove 24 and the first assembly surface 21' are provided with through holes for connecting with the fourth connecting part 42 in the steering column 4 by a first fastener (e.g., bolt or screw), that is, the first mounting part 21 and the fourth connecting part 42 in the steering column 4 are connected by a first fastener. As can be seen, since the two ends of the circumferential sidewall of the groove 24 are in contact with / abut against the first connecting surface and the first assembly surface 21' of the first mounting part 21 respectively, they play a supporting role between the first connecting surface and the first assembly surface 21' of the first mounting part 21, which can reduce or even avoid deformation of the first mounting part 21 and ensure that the first mounting part 21 has sufficient structural stability.

[0084] Correspondingly, in this crossbeam assembly, the side of the second mounting portion 22 that is close to and connected to the second crossbeam connecting unit 12 is the second connecting surface. A groove 24 recessed into the second hollow box is provided on this second connecting surface at the position for connection with the fourth connecting portion 42 in the steering column 4. Specifically, the circumferential sidewall of the groove 24 is located between the second connecting surface and the second assembly surface 22' of the second mounting portion 22, with one end connected to the second connecting surface and the other end connected to the bottom panel of the groove 24. The bottom panel of the groove 24 is close to or fits against the second assembly surface 22', and a through hole is provided at the corresponding position of the bottom panel of the groove 24 and the second assembly surface 22' for connection with the fourth connecting portion 42 via a second fastener (e.g., a bolt or screw). That is, the second mounting portion 22 and the fourth connecting portion 42 in the steering column 4 are connected via a second fastener. As can be seen, since the two ends of the circumferential sidewall of the groove 24 are respectively connected to / abut against the second connecting surface and the second assembly surface 22' of the second mounting part 22, they play a supporting role between the second connecting surface and the second assembly surface 22' of the second mounting part 22, which can reduce or even avoid deformation of the second mounting part 22 and ensure that the second mounting part 22 has sufficient structural stability.

[0085] In some embodiments, on the first connecting surface of the first mounting portion 21 near the first crossbeam connecting unit 11, a plurality of grooves 24 are distributed around the connection point between the first mounting portion 21 and the first mounting surface 21', except for the grooves 24, the area between the first connecting surface and the first mounting surface 21' is a hollow structure. Similarly, on the second connecting surface of the second mounting portion 22 near the second crossbeam connecting unit 12, a plurality of grooves 24 are distributed around the connection point between the second mounting portion 22 and the second mounting surface 22', except for the grooves 24, the area between the second connecting surface and the second mounting surface 22' is a hollow structure. That is, both the first mounting portion 21 and the second mounting portion 22 are hollow box structures. This structure can, to a certain extent, absorb vibration and reduce noise transmission, thereby improving the NVH properties of the crossbeam assembly and the vehicle body. Furthermore, sound-absorbing cotton can be added to the hollow box structure to further enhance the vibration damping and absorption effect at this location. It can be seen that the reinforcing structure formed by the groove 24, together with the hollow box structure of the first mounting part 21 and the second mounting part 22, can effectively improve the strength of the first mounting part 21 and the second mounting part 22 themselves, as well as their vertical strength at the connection position with the steering column 4, and is conducive to improving the NVH properties of the crossbeam assembly and the vehicle in which it is located.

[0086] Please see Figure 14As described above, in the first mounting part 21, the side connected to the first crossbeam connecting unit 11 is the first connecting surface, and the side located on the side of the first connecting surface and connected to the fourth connecting part 42 in the steering column 4 is the first assembly surface 21'. Since the first mounting part 21 is a hollow box structure, a first circumferential sidewall 211 is provided between the first connecting surface and the first assembly surface 21'. Preferably, the first circumferential sidewall 211 and the first assembly surface 21' are an integral structure, and the end of the first circumferential sidewall 211 away from the first assembly surface 21' abuts or is welded to the panel where the first connecting surface is located; moreover, the periphery of the first connecting surface is provided with a first outer extension edge 212 that protrudes radially outward relative to the first circumferential sidewall 211. Correspondingly, in the second mounting part 22, the side connected to the second crossbeam connecting unit 12 is the second connecting surface, and the side located on the side of the second connecting surface and connected to the fourth connecting part 42 in the steering column 4 is the second assembly surface 22'. Since the second mounting part 22 is a hollow box structure, a second circumferential sidewall 221 is provided between the second connecting surface and the second assembly surface 22'. Preferably, the second circumferential sidewall 221 and the second assembly surface 22' are an integral structure, and the end of the second circumferential sidewall 221 away from the second assembly surface 22' abuts or is welded to the panel where the second connecting surface is located; moreover, a second outer extension edge 222 is provided on the periphery of the second connecting surface, protruding radially outward relative to the second circumferential sidewall 221. In addition, in some embodiments, the connection between the first circumferential sidewall 211 and the first assembly surface 21' is an arc-shaped transition surface, and the connection between the second circumferential sidewall 221 and the second assembly surface 22' is an arc-shaped transition surface. In summary, the integrated structure and its arc-shaped transition surface not only facilitate manufacturing and assembly, but also help to disperse stress and enhance structural strength; the first outer extension edge 212 and the second outer extension edge 222 help to improve the structural strength of the first mounting part 21 and the second mounting part 22, and avoid problems such as cracking at the connection and structural deformation.

[0087] Normally, the first mounting portion 21 and the second mounting portion 22 are connected to the left and right sides of the fourth connecting portion 42, respectively. Furthermore, the upper surface of the fourth connecting portion 42 protrudes with a second boss 40 for connecting with the first mounting portion 21 and the second mounting portion 22; and / or, the lower surface of the fourth connecting portion 42 protrudes with a second boss 40 for connecting with the first mounting portion 21 and the second mounting portion 22. The first mounting portion 21 and its adjacent second boss 40 are each provided with through holes for mounting a first fastener, thereby enabling a fixed connection between the first mounting portion 21 and the steering column 4 via the first fastener; and / or, the second mounting portion 22 and its adjacent second boss 40 are each provided with through holes for mounting a second fastener, thereby enabling a fixed connection between the second mounting portion 22 and the steering column 4 via the second fastener.

[0088] Furthermore, in some embodiments, a fourth reinforcing rib 44 protrudes from the upper surface of the fourth connecting portion 42; and / or, a fourth reinforcing rib 44 protrudes from the lower surface of the fourth connecting portion 42. Specifically, multiple crisscrossing fourth reinforcing ribs 44 are respectively provided on the upper and lower surfaces of the fourth connecting portion 42. The multiple second bosses 40 and fourth reinforcing ribs 44 can effectively improve the structural strength of the steering column 4, avoiding problems such as noise or reliability issues caused by component deformation and loose connections. It can be seen that the crossbeam assembly provided in this application embodiment can not only save space above the steering column, but also optimize the modal properties of the steering column 4 and its connection positions, thereby improving the modal properties of the steering wheel system and the whole vehicle, and effectively solving the problem of steering wheel vibration.

[0089] Furthermore, the first mounting portion 21 and the second mounting portion 22 are also provided with a fifth connecting portion 43 for connecting to the front bulkhead of the vehicle body. The fifth connecting portion 43 includes a frame 431 and a connecting column 432. The frame 431 is basically U-shaped, with one leg connected to the first mounting portion 21 and the other leg connected to the second mounting portion 22. One end of the connecting column 432 is connected to the middle area of ​​the transverse rod in the U-shaped frame 431, and the other end is used for connecting to the front bulkhead of the vehicle body. The fifth connecting portion 43 of this bracket structure enables the connection between the crossbeam assembly and the front bulkhead of the vehicle body, which helps to ensure the stable installation of the crossbeam assembly in the vehicle body and also contributes to the structural stability of the crossbeam assembly and the front bulkhead of the vehicle body.

[0090] In specific implementation, such as Figure 13As shown, the third connecting portion 5 in the crossbeam assembly for connecting to the central channel can be configured as two parallel inclined beams. Both inclined beams are connected to either the first crossbeam connecting unit 11 or the second crossbeam connecting unit 12, or the two inclined beams are respectively connected to the first crossbeam connecting unit 11 and the second crossbeam connecting unit 12. Furthermore, the two inclined beams are respectively connected to both sides of the central channel or to the top of the central channel. In some embodiments, the second crossbeam connecting unit 12 includes a first column segment 121, a connecting segment 122, and a second column segment 123 connected in sequence. The first column segment 121 and the second column segment 123 are basically parallel. Furthermore, when the vehicle containing the crossbeam assembly is normally parked on the ground, the height of the first column segment 121 is higher than that of the second column segment 123; that is, the height distance between the first column segment 121 and the ground is greater than the height distance between the second column segment 123 and the ground. Additionally, the connecting segment 122 in the second crossbeam connecting unit 12 can be a rod-like structure or a plate-like structure, with one side of the connecting segment 122 adjacent to the first column segment 121 near the first crossbeam connecting unit. One end of element 11 is connected, and the other side of connecting segment 122 is connected to the end of second column segment 123 away from the first crossbeam connecting unit 11. Thus, the first column segment 121, connecting segment 122, and second column segment 123, connected in sequence, form a structure similar to the letter Z (the included angle at its corner is 90° or close to 90°). That is, the centerline extension direction of the first column segment 121 is basically perpendicular to the centerline extension direction of the connecting segment 122, and the centerline extension direction of the second column segment 123 is basically perpendicular to the centerline extension direction of the connecting segment 122. At this time, the two parallel inclined beams in the third connecting part 5 are connected to the first column segment 121 and the second column segment 123 respectively.

[0092] Please see Figure 15 and Figure 16The third embodiment of this application provides a crossbeam assembly, which differs from the first and second embodiments described above in that the target device installed at the disconnected position in this crossbeam assembly includes a steering column 4 and an air conditioning unit 3. Specifically, the accommodating space formed by the disconnected position between the first crossbeam connecting unit 11 and the second crossbeam connecting unit 12 is used to install the steering column 4 and the air conditioning unit 3. At this time, the steering column 4 and the air conditioning unit 3 constitute a total target device, and the disconnected position between the first crossbeam connecting unit 11 and the second crossbeam connecting unit 12 constitutes a total accommodating space. Specifically, this accommodating space includes two spatial units, respectively used for installing the steering column 4 and the air conditioning unit 3. Alternatively, the disconnected position between the first crossbeam connecting unit 11 and the second crossbeam connecting unit 12 can be considered as forming two accommodating spaces, respectively used for installing the steering column 4 and the air conditioning unit 3. The specific installation structure of the air conditioning unit 3 and the steering column 4 can be found in the first and second embodiments described above. The steering column 4 and the air conditioning unit 3 are connected by a connecting assembly.

[0093] In specific implementation, the left side of the steering column 4 is connected to the first mounting surface 21', and the right side is connected to the left side of the air conditioning unit 3 via a connecting assembly. The right side of the air conditioning unit 3 is connected to the second mounting surface 22'. The connecting assembly between the air conditioning unit 3 and the steering column 4 includes a connecting beam 13. One end of the connecting beam 13 is connected to the right side of the steering column 4 via a third mounting part 25 symmetrically arranged with the first mounting part 21, and the other end of the connecting beam 13 is connected to the left side of the air conditioning unit 3 via a fourth mounting part 26 symmetrically arranged with the second mounting part 22. The structure of the third mounting part 25 is basically the same as that of the first mounting part 21, and its installation direction is symmetrical to that of the first mounting part 21. The structure of the fourth mounting part 26 is basically the same as that of the second mounting part 22, and its installation direction is symmetrical to that of the second mounting part 22. Thus, the first crossbeam connecting unit 11, the first mounting part 21, the steering column 4, the third mounting part 25, the connecting beam 13, the fourth mounting part 26, the air conditioning unit 3, the second mounting part 22, and the second crossbeam connecting unit 12 are connected sequentially. Thus, a spatial unit for mounting the steering column 4 is formed between the first mounting part 21 and the third mounting part 25. The steering column 4 is located in this spatial unit and is connected to the first mounting part 21 and the third mounting part 25 on both sides, respectively. A spatial unit for mounting the air conditioning unit 3 is formed between the second mounting part 22 and the fourth mounting part 26. The air conditioning unit 3 is located in this spatial unit and is connected to the second mounting part 22 and the fourth mounting part 26 on both sides, respectively. At this time, both of the above spatial units are located in the accommodating space formed by the first mounting surface 21' of the first mounting part 21 and the second mounting surface 22' of the second mounting part 22. The steering column 4 and the air conditioning unit 3 are connected by the third mounting part 25, the connecting beam 13, and the fourth mounting part 26 to form a general target device. Its left side is connected to the first crossbeam connecting unit 11 through the first mounting part 21, and its right side is connected to the second crossbeam connecting unit 12 through the second mounting part 22.

[0094] In summary, this application also provides a vehicle in which a crossbeam assembly as described in any of the specific embodiments above and a target device installed at the disconnected position of the crossbeam assembly are disposed between the left and right sides of the vehicle body.

[0095] In specific implementation, a left A-pillar is provided in the left side of the vehicle body, and a right A-pillar is provided in the right side of the vehicle body. The first crossbeam connecting unit 11 and the second crossbeam connecting unit 12 in the aforementioned crossbeam assembly can be connected to the left A-pillar and the right A-pillar, respectively. The target device (e.g., steering column 4 and / or air conditioning unit 3) is located between the first crossbeam connecting unit 11 and the second crossbeam connecting unit 12, and both sides of the target device are connected to the first mounting surface 21' of the first mounting part 21 and the second mounting surface 22' of the second mounting part 22, respectively.
