[0046] In order to make the purpose, technical solution and advantages of the embodiment of the utility model clearer, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is a part of the embodiment of the utility model, not all the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the utility model.

[0047] Combine the following Figure 1-Figure 13 , describing an embodiment of the utility model.

[0048] According to an embodiment of the present utility model, on the one hand, an instrument beam assembly is provided, such as Figure 1-Figure 4 As shown, it includes: a beam body 1 , a mounting bracket 2 , a mounting portion 201 , a bearing portion 202 and a weak portion 203 .

[0049] The crossbeam body 1 is provided with a first mounting position 1021; the mounting bracket 2 includes a mounting portion 201, a bearing portion 202 and a weak portion 203, the mounting portion 201 is detachably connected to the first mounting position 1021, the bearing portion 202 is suitable for being connected to the front panel of the car, and the weak portion 203 is located between the mounting portion 201 and the bearing portion 202; when the front panel of the car is hit, the weak portion 203 is suitable for absorbing the impact energy from the front panel of the car.

[0050] In the above embodiment, the mounting portion 201 of the mounting bracket 2 is connected to the first mounting position 1021 of the cross beam body 1 to form an integrated instrument cross beam assembly; when the front of the car is hit, the bearing portion 202 of the mounting bracket 2 connected to the front of the car is impacted first, and the weak portion 203 is used to absorb the impact energy and deform or crush itself to protect the cross beam body 1; the detachable connection between the mounting bracket 2 and the cross beam body 1 facilitates the independent replacement of the mounting bracket 2 after crushing damage, so there is no need to replace the instrument cross beam assembly as a whole, thereby improving the economic efficiency of vehicle maintenance. This solves the problem that the current instrument cross beam assembly needs to be replaced as a whole after being damaged, resulting in poor economic efficiency of vehicle maintenance.

[0051] Specifically, Figure 1-Figure 3 As shown, the mounting bracket 2 is used as a workpiece that withstands impact in the instrument cross beam assembly, and is connected to the first mounting position 1021 of the cross beam body 1 through the mounting portion 201, thereby forming the overall structure of the instrument cross beam assembly; when the front wall of the car is hit, the bearing portion 202 of the mounting bracket 2 connected to the front wall of the car is first impacted, and the impact force is transmitted along the extending direction of the mounting bracket 2 to the cross beam body 1. During the impact force transmission process, the weak portion 203 set between the mounting portion 201 and the bearing portion 202 on the mounting bracket 2 is used to absorb the impact energy, so that the mounting bracket 2 The mounting bracket 2 itself is deformed or crushed, and the impact force will be greatly reduced or even completely absorbed by the mounting bracket 2 when it is transmitted to the beam body 1, so that the mounting bracket 2 can protect the beam body 1 while absorbing the impact energy, thereby preventing the expensive beam body 1 from being damaged by the impact; the mounting portion 201 of the mounting bracket 2 is configured to be detachably connected to the first mounting position 1021 of the beam body 1, so that the mounting bracket 2 can be replaced independently after being crushed and damaged, thereby eliminating the need to replace the instrument beam assembly as a whole, thereby improving the economy of vehicle maintenance.

[0052] Furthermore, if Figure 3As shown, this embodiment does not restrict the structural form of the weak part 203 on the mounting bracket 2, so that the structural strength of the weak part 203 is less than the structural strength of the mounting part 201 and the bearing part 202, and the weak part 203 can be deformed or crushed by using the lower structural strength when an impact occurs. Therefore, under the condition of meeting the above requirements, the structural form of the mounting bracket 2 includes at least the following three considerations: first, in terms of materials, plastics, mild steel and other materials with lower structural strength are selected as the molding materials of the weak part 203, and alloys, high-hardness steel and other materials with higher structural strength are used as the molding materials of the mounting part 201 and the bearing part 202. After being connected to each other, the mounting bracket 2 is formed, so that the structural strength of the weak part 203 is much smaller than the structural strength of the mounting part 201 and the bearing part 202, so as to meet the requirements of deformation or crushing of the designated position after the impact; second, in terms of structure, reinforcing members or reinforcing structures are set in the mounting part 201 and the bearing part 202, and no adjustment is made to the weak part 203 or only a reinforcing member is set. A support member or a support structure is provided to support its own structural strength, so that the structural strength of the weak portion 203 is much smaller than that of the mounting portion 201 and the bearing portion 202, so as to meet the requirement of deformation or crushing at a designated position after being impacted, for example, a weakening groove is provided at the position of the weak portion 203; thirdly, in terms of size, the mounting portion 201 and the bearing portion 202 are provided to be larger in size than the weak portion 203, that is, the mounting bracket 2 is provided to be thin in the middle and thick at both ends, similar to a structure in the form of two triangles connected at the apex angles, so that the structural strength of the weak portion 203 located in the middle is much smaller than that of the mounting portion 201 and the bearing portion 202, so as to meet the requirement of deformation or crushing at a designated position after being impacted.

[0053] Furthermore, in this embodiment, the mounting bracket 2 can only serve as a support member connected to the front panel of the automobile. In this case, multiple mounting brackets 2 can be provided along the length extension direction of the crossbeam body 1; or the mounting bracket 2 can serve as a support member connected to the front panel of the automobile and as one of the mounting positions of the steering column 100, so as to provide an installation position for the steering column 100.

[0054] Furthermore, this embodiment does not limit the specific form of the detachable connection between the cross beam body 1 and the mounting bracket 2 between the first mounting position 1021 and the mounting portion 201. The specific detachable connection form at least includes bolt connection, snap connection, etc. In this embodiment, Figure 1-Figure 4As shown, the cross beam body 1 and the mounting bracket 2 are connected by bolts between the first mounting position 1021 and the mounting portion 201. Specifically, two first connection holes 2011 and two second connection holes 2012 are provided on the first mounting portion 201, the first mounting position 1021 is provided with a groove that is shaped like the first mounting portion 201, and four through holes that penetrate the groove wall corresponding to the first connection holes 2011 and the second connection holes 2012 are provided, and the cross beam body 1 and the mounting bracket 2 are fastened between the first mounting position 1021 and the mounting portion 201 by four bolts. When the mounting bracket 2 is deformed or crushed due to impact and the damaged mounting bracket 2 needs to be replaced, it is only necessary to remove the bolts and the damaged mounting bracket 2, install the mounting portion 201 of the new mounting bracket 2 in the shaped groove of the first mounting position 1021, and fasten the cross beam body 1 and the mounting bracket 2 again by four bolts.

[0055] Furthermore, if Figure 1-Figure 4 As shown, a connecting boss 2023 is provided at the end of the bearing portion 202 on the mounting bracket 2. The connecting boss 2023 is used to connect the mounting bracket 2 and the instrument cross beam assembly to the front enclosure of the automobile. The specific connection method between the connecting boss 2023 and the front enclosure of the automobile can be welding, snap-on connection, etc.

[0056] In some embodiments, Figure 3 , Figure 4 As shown, the width of the weak portion 203 is smaller than the width of the mounting portion 201 and / or the bearing portion 202 .

[0057] In the above embodiment, the mounting portion 201 and the bearing portion 202 are set to have larger dimensions than the weak portion 203, so that the structural strength of the weak portion 203 located in the middle is much smaller than the structural strength of the mounting portion 201 and the bearing portion 202, so as to meet the requirement that the weak portion 203 is deformed or crushed after the mounting bracket 2 is impacted.

[0058] Specifically, Figure 3 , Figure 4 As shown, this embodiment only shows an implementation method in which the width of the weak portion 203 is smaller than the width of the mounting portion 201 on one side of the mounting bracket 2. Since the bearing portion 202 needs to be connected to the front wall of the car, and most of the structures on the side of the connecting boss 2023 in the bearing portion 202 will be snapped into the corresponding recessed structure in the front wall of the car, which can further improve the structural strength of this part of the structure of the bearing portion 202, there is no need to make too many restrictions on the size specifications of the position of the bearing portion 202. It is only necessary that the width of the portion of the bearing portion 202 exposed at the connection position of the front wall of the car is not less than the width of the weak portion 203. Of course, setting the width of the weak portion 203 to be smaller than the width of the bearing portion 202 can achieve a better effect. Reasonable reduction in the size specifications of the bearing portion 202 can also reduce production costs and is conducive to the development of lightweight automobiles.

[0059] Furthermore, in addition to setting only the width of the weak portion 203 to be smaller than the width of the mounting portion 201, as an alternative embodiment, only the width of the weak portion 203 can be set to be smaller than the width of the bearing portion 202, or the width of the weak portion 203 can be set to be smaller than the width of both the mounting portion 201 and the bearing portion 202.

[0060] In some embodiments, Figure 3 As shown, the interior of the mounting portion 201 and / or the bearing portion 202 is a cavity and is provided with a reinforcing structure 3 , which is suitable for supporting the inner wall of the mounting portion 201 and / or the bearing portion 202 .

[0061] In the above embodiment, a reinforcing structure 3 is provided at the mounting portion 201 and the bearing portion 202 to provide reinforcing support for the corresponding position of the mounting bracket 2, so that the structural strength of the weak portion 203 located in the middle is much smaller than the structural strength of the mounting portion 201 and the bearing portion 202, so as to meet the requirement that the weak portion 203 of the mounting bracket 2 is deformed or crushed after being impacted.

[0062] Specifically, Figure 3 , Figure 4 As shown, in this embodiment, the reinforcing structure 3 is only provided on the side of the bearing portion 202 on the mounting bracket 2. Since the mounting portion 201 is connected to the cross beam body 1, and the mounting portion 201 is clamped and screwed with the corresponding recessed structure in the cross beam body 1 to form an integral structure, the structural strength of the mounting portion 201 can be further improved. Therefore, there is no need to make too many restrictions on the internal support at the mounting portion 201, and the internal support structure can be arranged in a conventional manner. Of course, the reinforcing structure 3 is provided on the side of the mounting portion 201 on the mounting bracket 2 to achieve a better effect. The mounting portion 201 is arranged with an internal support structure in a conventional manner, which can also reduce production costs and is conducive to the development of lightweight vehicles.

[0063] Furthermore, in addition to providing the reinforcing structure 3 only on the side of the bearing portion 202 on the mounting bracket 2, as an alternative embodiment, the reinforcing structure 3 may be provided only on the side of the mounting portion 201 on the mounting bracket 2, or the reinforcing structure 3 may be provided on both sides of the mounting portion 201 and the bearing portion 202 on the mounting bracket 2.

[0064] Furthermore, if Figure 4 As shown, the interior of the weak portion 203 is a cavity and is provided with a support structure 4, which is used to support the inner wall of the weak portion 203. The support structure 4 plays a supporting role at the weak portion 203 to ensure the overall structural strength level of the mounting bracket 2 and avoid damage in a slight collision.

[0065] In some embodiments, Figure 3 As shown, the reinforcement structure 3 includes a plurality of cross-arranged first partitions 301 ; at least any one of the first partitions 301 is connected to the inner wall of the mounting portion 201 , and / or at least any one of the first partitions 301 is connected to the inner wall of the bearing portion 202 .

[0066] In the above embodiment, a reinforcing structure 3 is formed by providing a cross-arranged first partition 301 on the inner walls of the mounting portion 201 and the bearing portion 202, thereby reinforcing the corresponding positions in the mounting portion 201 and the bearing portion 202 to ensure the structural strength requirements of the mounting portion 201 and the bearing portion 202.

[0067] Specifically, Figure 3 As shown, in this embodiment, the first partition plates 301 are cross-arranged only on the side of the bearing portion 202 of the mounting bracket 2 .

[0068] Furthermore, in addition to cross-arranging the first partitions 301 only on the side of the bearing portion 202 on the mounting bracket 2, as an alternative embodiment, the first partitions 301 can also be cross-arranged only on the side of the mounting portion 201 on the mounting bracket 2, or the first partitions 301 can be cross-arranged in the corresponding cavity positions on both sides of the mounting portion 201 and the bearing portion 202 on the mounting bracket 2.

[0069] Furthermore, if Figure 4 As shown, in this embodiment, the support structure 4 includes a plurality of second baffles 401 arranged in parallel, and at least any second baffle 401 is connected to the inner wall of the weak portion 203. Thus, the plurality of second baffles 401 arranged in parallel play a supporting role at the weak portion 203, thereby ensuring the overall structural strength level of the mounting bracket 2 and avoiding damage in a slight collision. However, the second baffles 401 arranged in parallel will become unstable under the large load of a strong collision, and will be deformed or crushed.

[0070] In some embodiments, Figure 5 As shown, the crossbeam body 1 and the mounting bracket 2 are suitable for connecting to the steering column 100, and the steering column 100 has a first connection point 1001 close to the steering wheel 200, and a second connection point 1002 away from the steering wheel 200; a second mounting position 1022 is provided on the side of the crossbeam body 1 away from the first mounting position 1021, and the second mounting position 1022 is suitable for connecting to the first connection point 1001; at least part of the structure of the bearing portion 202 extends in a direction away from the weak portion 203 to form an extension structure 2021, and the extension structure 2021 is provided with a third mounting position 2022, and the third mounting position 2022 is suitable for connecting to the second connection point 1002.

[0071] In the above embodiment, the second mounting position 1022 on the cross beam body 1 is used as the upper connection position of the steering column 100, and the third mounting position 2022 provided on the extension structure 2021 extending from the bearing portion 202 is used as the lower connection position for connecting the steering column 100, so that the cross beam body 1 and the mounting bracket 2 can be used to provide a mounting position for the steering column 100; and the mounting bracket 2 serves as a support member for connecting the front panel of the automobile, and also serves as one of the mounting positions of the steering column 100, thereby realizing the dual use of the mounting bracket 2.

[0072] Specifically, Figure 5 As shown, the second installation position 1022 is connected to the first connection point 1001 by bolts, and the third installation position 2022 is connected to the second connection point 1002 by bolts. The first connection point 1001 is located above the second connection point 1002, so that the steering column 100 is tilted toward the driver after installation, so that the driver can operate the steering wheel 200 at one end of the steering column 100.

[0073] In some embodiments, Figure 5-Figure 9 As shown, the mounting bracket 2 further includes a bending structure 2031 located on the weak portion 203 and close to the extending structure 2021 . The bending structure 2031 is formed by at least a portion of the structure of the weak portion 203 being recessed inwardly.

[0074] In the above embodiment, when the front panel of the automobile is hit, by providing a bending structure 2031 on the weak portion 203 close to the side of the extension structure 2021, it is possible to induce the partial structure on the mounting bracket 2 close to the side of the front panel of the automobile to flip and deform in the direction of the mounting bracket 2 close to the crossbeam body 1, so that the side of the steering column 100 close to the steering wheel 200 rotates close to the crossbeam body 1, thereby driving the steering wheel 200 away from the driver, expanding the space between the steering wheel 200 and the driver, and preventing the steering wheel 200 from encroaching on the living space in front of the driver's abdomen and chest after a collision.

[0075] Specifically, Figure 7As shown, the cylinder is where the driver's abdomen and chest are located. When the front of the car is hit, the bending structure 2031 at the bottom of the weak part 203 is impacted, and the impact force acts on the part of the structure on the mounting bracket 2 close to the front of the car, that is, the lower part of the bearing part 202 on the side of the weak part 203 in the figure. Under the action of the bending structure 2031, the lower part of the bearing part 202 is turned over and deformed in the direction of the mounting bracket 2 close to the crossbeam body 1, that is, in the direction of the mounting part 201 on the other side of the weak part 203 in the figure, that is, along the direction of the curved arrow in the figure, and the bearing part The flipping deformation of 202 drives the extension structure 2021, the third mounting position 2022 and the second connection point 1002 on the lower side of the steering column 100 to move together, so that the side of the steering column 100 close to the steering wheel 200 rotates counterclockwise along the direction of the straight arrow in the figure, close to the crossbeam body 1, thereby driving the steering wheel 200 away from the driver, and expanding the spatial distance between the steering wheel 200 and the driver from the original length shown by L1 to the length shown by L2 after the collision, thereby expanding the space between the steering wheel 200 and the driver.

[0076] In some embodiments, Fig.10 As shown, the beam body 1 includes a first body 101 and a second body 102 connected to the first body 101 , and the material density of the second body 102 is less than the material density of the first body 101 .

[0077] In the above embodiment, the main structural beam body 1 of the instrument beam assembly is set as a two-part assembly structure of a first body 101 and a second body 102, which reduces the material density of the second body 102 while ensuring the structural strength, which is conducive to the lightweight development of the instrument beam assembly.

[0078] Specifically, Fig.10 As shown, the first body 101 with a larger material density serves as a main support member to provide most of the support for the instrument beam assembly, and the second body 102 with a smaller material density serves as a secondary support member to provide auxiliary support for the instrument beam assembly.

[0079] Furthermore, in this embodiment, there is no restriction on the connection form between the first body 101 and the second body 102.
