[0029] In the description of this application, unless otherwise clearly defined, words such as setting and connecting should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above words in this application based on the specific content of the technical solution.

[0030] The technical solution of the present application will be further described below in conjunction with embodiments and drawings.

[0031] It can be understood that in the embodiments of the present application, the positive direction of the X-axis in the drawings is the front, the negative direction of the X-axis is the back, the positive direction of the Z-axis is the top, and the negative direction of the Z-axis is the bottom.

[0032] See also Figures 1 to 3 The first embodiment of the present application provides a bracket 100 for mounting automobile parts on an automobile body, which can reduce the impact force generated by the bracket 100 and the automobile parts mounted thereon when the automobile collides, thereby enhancing the safety of the automobile.

[0033] The bracket 100 includes a first mounting position 111, a second mounting position 121 and a fragile portion. The first mounting position 111 and the second mounting position 121 are respectively provided at both ends of the bracket 100 so as to install the bracket 100 on the automobile body. The mounting strength of the first mounting position 111 is lower than the mounting strength of the second mounting position 121. A fragile portion is formed on the bracket 100, and the fragile portion includes a first fragile portion 151. The bracket 100 can be divided into a first area 110 and a second area 120 through a vertical plane where the first fragile portion 151 is located. The first mounting position 111 is provided in the first area 110, and the second mounting position 121 is provided in the second area 120. A connection position is provided on the first area 110, and the automobile parts are connected through The connection position is connected to the bracket 100; it is understandable that the automobile component is fixedly connected to the bracket 100 through the connection position, but the size of the automobile component is not limited to the range of the connection position. For example, the automobile component can also be partially placed on the second area 120; when the car collides, under the action of the collision impact force, the first installation position 111 can fall off the car body, and the installation strength of the second installation position 121 is higher than the installation strength of the first installation position 111, so that the second installation position 121 can continue to maintain a state of connection with the car body, and the first fragile part 151 can serve as a trigger point for the bracket 100 to fold, so that the part of the bracket 100 installed with the automobile component can be folded downward. It is understandable that the bracket 100 that is partially folded downward is located in the first area 110.

[0034] Since the bracket 100 can absorb part of the collision energy and fold, the collision impact force can be effectively reduced, and the part of the bracket 100 installed with the automobile parts can be folded downward, which can increase the crushing space and effectively prevent the bracket 100 installed with the automobile parts from approaching the passenger compartment, which is conducive to enhancing the collision safety of the automobile and ensuring the safety of the people in the passenger compartment. In addition, the bracket 100 with this structure can increase the selection range of automobile parts that can be installed, and automobile parts with larger size and mass can be appropriately selected for installation.

[0035] In some embodiments, the bracket 100 is transversely mounted on the vehicle body, and the first fragile portion 151 extends along the length direction of the bracket 100 .

[0036] Exemplarily, the bracket 100 has a width direction (i.e. Figure 1The bracket 100 is provided with a first end and a second end (in the X-axis direction in the middle), a first mounting position 111 is provided on the first end, and a second mounting position 121 is provided on the second end, so that the bracket 100 is transversely mounted on the front end of the automobile body. When the front end of the automobile collides, the bracket 100 can absorb part of the collision energy and fold, which can effectively reduce the impact of the collision, and part of the bracket 100 installed with automobile parts can be folded downward, which can effectively prevent the bracket 100 installed with automobile parts from moving backward close to the passenger compartment, which is conducive to enhancing the collision safety of the automobile and ensuring the safety of people in the passenger compartment.

[0037] It is understandable that the bracket 100 can also be installed at the rear end of the vehicle body. The specific position and specific manner of installing the bracket 100 on the vehicle body can be set according to actual needs and are not specifically limited here.

[0038] Alternatively, see Figure 1 , the first area 110 is located at the rear side of the second area 120, that is, the first installation position 111 is located at the rear side of the second installation position 121. Of course, the first area 110 can also be located at the front side of the second area 120, so that the first area 110 is farther away from the passenger compartment than the second area 120. When the front end of the car collides, the part of the bracket 100 (located in the first area 110) on which the car parts are installed can be folded down, so that the passenger compartment and the part of the bracket 100 on which the car parts are installed can maintain a safer distance, thereby better ensuring the safety of the people in the passenger compartment.

[0039] Optionally, the area of ​​the first zone 110 may be larger than the area of ​​the second zone 120 to facilitate mounting of automobile components.

[0040] In some embodiments, at least one first connecting member is disposed on the first installation position 111 , and at least one second connecting member is disposed on the second installation position 121 for connection with the vehicle body.

[0041] Exemplarily, two first connecting members are provided on the first installation position 111, and the two first connecting members are respectively provided at both ends of the bracket 100 along its length direction, and two second connecting members are provided on the second installation position 121, and the two second connecting members are respectively provided at both ends of the bracket 100 along its length direction.

[0042] Of course, one first connection member may be provided on the first installation position 111, and one second connection member may be provided on the second installation position 121; or, multiple first connection members may be provided on the first installation position 111, and multiple second connection members may be provided on the second installation position 121; or, multiple first connection members may be provided on the first installation position 111, and multiple first connection members and multiple second connection members may be provided on the second installation position 121. It is understood that the specific number and specific location of the first connection member and the second connection member may be provided according to actual needs, as long as the installation strength of the first installation position 111 is ensured to be lower than that of the second installation position 121, and no specific limitation is made here.

[0043] In some embodiments, see Figure 2 The first connecting member is a first bolt 130, and the second connecting member is a second bolt 140. Of course, the first connecting member and the second connecting member may also be fasteners such as screws and rivets, and no specific limitation is made here.

[0044] The following is explained by taking “two first bolts 130 are provided on the first installation position 111, and the two first bolts 130 are respectively provided at the two ends of the bracket 100 along its length direction, and two second bolts 140 are provided on the second installation position 121, and the two second bolts 140 are respectively provided at the two ends of the bracket 100 along its length direction” as an example.

[0045] It is understandable that the performance grades of bolts for steel structure connections are divided into more than 10 grades, including 3.6, 4.6, 4.8, 5.6, 6.8, 8.8, 9.8, 10.9, 12.9, etc. Among them, bolts of grade 8.8 and above are made of low-carbon alloy steel or medium-carbon steel and are heat-treated (quenched and tempered), which are generally called high-strength bolts, and the rest are generally called ordinary bolts. The higher the performance grade of the bolt, the higher its nominal tensile strength value and yield strength ratio, and the higher the installation strength of the installation position.

[0046] In order to make the installation strength of the first installation position 111 lower than the installation strength of the second installation position 121 and meet the strength requirements for the normal installation of automobile parts, the performance level of the first bolt 130 can be less than or equal to level 8.8, and the performance level of the second bolt 140 can be greater than or equal to level 12.9.

[0047] In some of the embodiments, see Figure 4 The automobile body is provided with a mounting bracket 221 above the bracket 100, the first bolt 130 is passed through the bracket 100 to be connected with the mounting bracket 221, and the first bolt head 121 of the first bolt 130 is located below the bracket 100 (see Figure 3 ), the second bolt 140 is passed through the bracket 100 to be connected to the mounting bracket 221, and the second bolt head 141 of the second bolt 140 is located above the bracket 100 (see Figure 3 ).

[0048] Exemplarily, the mounting bracket 221 includes a vertical portion and a horizontal portion connected to each other, the vertical portion is connected to the vehicle body, and the horizontal portion is connected to the bracket 100 .

[0049] It can be understood that bolts are generally matched with nuts, so the first nut matched with the first bolt 130 is located on the side of the horizontal part of the mounting bracket 221 away from the bracket 100 (that is, the first nut is located above the horizontal part of the mounting bracket 221), and the second nut matched with the second bolt 140 is located on the side of the bracket 100 away from the horizontal part of the mounting bracket 221 (that is, the second nut is located below the bracket 100). Since the bolt head and the screw of the bolt are integrally formed, the connection strength between the bolt head and the screw of the bolt is generally greater than the connection strength between the screw and the nut of the bolt. Therefore, under the same external force, the connection between the screw and the nut of the bolt is easier to be damaged than the connection between the screw and the bolt head. Therefore, the connection between the first bolt 130 and the mounting bracket 221 (the connection between the screw and the nut) is easier to be damaged under the action of the collision force than the connection between the second bolt 140 and the horizontal part of the mounting bracket 221 (the connection between the screw and the bolt head). Therefore, this structure can further realize the technical requirement that "the installation strength of the first installation position 111 is lower than the installation strength of the second installation position 121", and can also meet the strength requirements for the normal installation of automobile parts.

[0050] Optionally, the length of the first bolt 130 extending from the bracket 100 is less than the length of the second bolt 140 extending from the bracket 100, so that the first bolt 130 is easier to fall off from the horizontal part of the mounting bracket 221 than the second bolt 140 under the action of the collision force.

[0051] In other embodiments, the first connecting member may be a pin, and the second connecting member may be a second bolt 140 , and a thread is provided on the screw rod of the second bolt 140 along the length direction thereof.

[0052] It can be understood that, compared with the pin, the screw rod of the second bolt 140 is more tightly matched with the bracket 100, the mounting bracket 221 and the nut under the action of friction. Therefore, this structure can further achieve the technical requirement of "the mounting strength of the first mounting position 111 is lower than the mounting strength of the second mounting position 121", and can also meet the strength requirements of the usual installation of automobile parts.

[0053] It is understandable that, in actual applications, the actual arrangement of the first connecting member and the second connecting member on the first installation position 111 and the second installation position 121 may be determined through a collision test.

[0054] In some embodiments, the first fragile portion 151 is a linear fragile portion and is parallel to the long side of the bracket 100 .

[0055] It is understandable that the first fragile portion 151 may also be a fragile portion in other shapes such as a curved shape or a sawtooth shape, and no specific limitation is made herein.

[0056] Alternatively, see Figure 3 The cross section of the first fragile portion 151 is an arc-shaped groove. Of course, the cross section of the first fragile portion 151 can also be a folded line groove or a groove of other shapes, which is not specifically limited here.

[0057] Optionally, both ends of the first fragile portion 151 may be flush with both ends of the bracket 100 along the long side direction. Optionally, the first fragile portion 151 may be disposed on the lower surface of the bracket 100 (see Figure 3 ).

[0058] The fragile portion may also include a second fragile portion, a third fragile portion, and multiple fragile portions. For example, the fragile portion includes a first fragile portion 151 and a second fragile portion parallel to the long side of the bracket 100, and the first fragile portion 151 and the second fragile portion are spaced apart along the long side direction of the bracket 100; for another example, the fragile portion includes a first fragile portion 151 and a second fragile portion parallel to the long side of the bracket 100, and the first fragile portion 151 and the second fragile portion are spaced apart along the width direction of the bracket 100; for another example, the fragile portion includes a first fragile portion 151 and a second fragile portion parallel to the long side of the bracket 100, and the first fragile portion 151 is arranged on the upper surface of the bracket 100, and the second fragile portion is arranged on the lower surface of the bracket 100.

[0059] The specific number and location of the fragile parts can be set according to actual needs and are not specifically limited here.

[0060] In some embodiments, the bracket 100 can be telescopically arranged along its length direction (not shown in the drawings), so that the length of the bracket 100 can be adjusted, thereby enabling the bracket 100 to be suitable for installing automobile parts on automobile bodies of different body widths, reducing the mold opening cost and mold opening time of the bracket 100, and improving installation efficiency.

[0061] Exemplarily, the bracket 100 includes a first part and a second part arranged along its length direction, and also includes a fastener. The first part has a plurality of first through holes arranged at intervals along its length direction, and the second part has a plurality of second through holes arranged at intervals along its length direction. By inserting the fasteners into different first through holes and second through holes, the length of the bracket 100 can be adjusted.

[0062] Exemplarily, the fastener may be a fastening bolt, but of course, the fastener may also be other fasteners such as a screw or a pin, which are not specifically limited here.

[0063] Of course, the first part can also be connected to the second part through an electric telescopic rod, and the electric telescopic rod is electrically connected to a driving motor. The driving motor can control the electric telescopic rod to extend or shorten to adjust the length of the bracket 100.

[0064] In some embodiments, the cradle 100 is an EV cradle.

[0065] Other structures and operations of the bracket 100 according to the first embodiment of the present application are known to ordinary technicians in the field and will not be described in detail here.

[0066] A second aspect of the present application provides a car, which includes the bracket 100 of the first aspect of the present application and a car body, and the bracket 100 is mounted on the car body.

[0067] For example, see Figure 5 The automobile body includes a firewall 210 and load-bearing walls 220 arranged on both sides. The bracket 100 is installed on the load-bearing walls 220 on both sides through the first installation position 111 and the second installation position 121. The firewall 210 is arranged at the rear side of the bracket 100, and the passenger compartment is located at the rear side of the firewall 210. Further, a mounting bracket 221 is arranged on each of the load-bearing walls 220 on both sides, and the bracket 100 is connected to the corresponding mounting bracket 221 through the first bolt 130 and the second bolt 140.

[0068] Exemplarily, the automobile component mounted on the bracket 100 is a motor controller 300, and the motor controller 300 is mounted on the first area 110 of the bracket 100 through a connection position. Further, the motor controller 300 is mounted on the connection position of the first area 110 of the bracket 100 through bolts.

[0069] Of course, the automobile component mounted on the bracket 100 may also be an automobile component such as a PTC component, a three-in-one electric drive system or a two-in-one electric drive system, and no specific limitation is made here.

[0070] See also Figure 6 When the front end of the car collides, the bracket 100 can absorb part of the collision energy and fold, which can effectively reduce the impact force of the collision, and the part of the bracket 100 (located in the first area 110) installed with the car parts can be folded downward, so that the passenger compartment and the part of the bracket 100 installed with the car parts can maintain a safe distance, which is beneficial to enhance the collision safety of the car and ensure the safety of people in the passenger compartment.

[0071] Other structures and operations of the automobile according to the embodiment of the second aspect of the present application are known to ordinary technicians in the field and will not be described in detail here.

[0072] The embodiments of the present application are described in detail above in conjunction with the accompanying drawings, but the present application is not limited to the above embodiments, and various changes can be made within the knowledge scope of ordinary technicians in the technical field without departing from the purpose of the present application.
