[0029] A vehicle 100 according to an embodiment of the present invention will be described below with reference to the accompanying drawings.
[0030] like Figure 1As shown, a vehicle 100 according to an embodiment of the present invention includes a powertrain 1 , a subframe assembly 2 and a suspension assembly 3 .
[0031] Specifically, refer to the attached Figure 1 As shown, the power assembly 1 generally includes components such as an engine, a transmission, and a clutch to enable the vehicle 100 to operate. The subframe assembly 2 is disposed on the lower side of the power assembly 1 (such as Figure 1 As shown in the figure, it is used to support the front and rear axles and the suspension. The suspension assembly 3 includes a suspension bracket body 31 and a suspension crushing mechanism 32. The suspension bracket body 31 is connected to the subframe assembly 2. The suspension bracket body 31 has a mounting groove 311. The suspension crushing mechanism 32 is arranged in the mounting groove 311 and is connected to the suspension bracket body 31. The suspension crushing mechanism 32 is connected to the powertrain 1. The setting of the suspension assembly 3 can support the powertrain 1 and suppress the vibration generated by the powertrain 1.
[0032] It can be understood that when the vehicle 100 is in a normal state, the suspension bracket body 31 is connected to the subframe assembly 2, the suspension crushing mechanism 32 is connected to the powertrain 1, and the suspension crushing mechanism 32 is arranged in the installation groove 311 and connected to the suspension bracket body 31, so that the suspension assembly 3 can be connected to the powertrain 1 and the subframe assembly 2, and the normal operation of the vehicle 100 can be achieved.
[0033] When the vehicle 100 is subjected to a frontal collision or is in a collision test, the subframe assembly 2 is subjected to a frontal collision force, driving the suspension bracket body 31 backward (such as Figure 1 As shown in the figure, the power assembly 1 is also connected to the cooling system, the fuel system and the exhaust system, which can play a fixing role on the power assembly 1. Therefore, the fixing force on the power assembly 1 and the frontal collision force transmitted by the suspension bracket body 31 act on the power assembly 1 at the same time. When the frontal collision force reaches a certain magnitude, the suspension collapse mechanism 32 disengages from the mounting groove 311 and disconnects from the suspension bracket body 31, thereby canceling the indirect connection between the power assembly 1 and the sub-frame assembly 2, so that the sub-frame assembly 2 and the suspension bracket body 31 can continue to move rearward without pushing the power assembly 1 to move backward, thereby reducing the collision between the power assembly 1 and structures such as the front panel, improving the score of the vehicle 100 in the collision test, reducing the collision damage suffered by the driver and passengers, and protecting the safety of the driver and passengers.
[0034] Compared with the rigid connection between the suspension bracket and the powertrain in the prior art, the utility model adds a suspension crushing mechanism 32, which can cancel the connection between the suspension crushing mechanism 32 and the suspension bracket body 31 when the vehicle 100 is subjected to a head-on collision or is in a collision test. The suspension crushing mechanism 32 is connected to the powertrain 1, and the suspension bracket body 31 is connected to the subframe assembly 2, thereby canceling the indirect connection between the powertrain 1 and the subframe assembly 2, thereby avoiding to a certain extent that the subframe assembly 2 drives the powertrain 1 to move backward and collide with the front panel and other structures, thereby improving the score of the vehicle 100 in the collision test, reducing the collision damage to the driver and passengers, and protecting the safety of the driver and passengers.
[0035] According to the vehicle 100 of the embodiment of the utility model, the suspension assembly 3 includes a suspension bracket body 31 and a suspension crushing mechanism 32. The suspension bracket body 31 is connected to the sub-frame assembly 2. The suspension bracket body 31 has a mounting groove 311. The suspension crushing mechanism 32 is arranged in the mounting groove 311 and is connected to the suspension bracket body 31. The suspension crushing mechanism 32 is connected to the powertrain 1. When the vehicle 100 is subjected to a head-on collision or is in a collision test, the connection between the suspension crushing mechanism 32 and the suspension bracket body 31 can be cancelled, and the indirect connection between the powertrain 1 and the sub-frame assembly 2 can be cancelled, thereby avoiding to a certain extent that the sub-frame assembly 2 drives the powertrain 1 to move backward, thereby improving the score of the vehicle 100 in the collision test, reducing the collision damage suffered by the driver and passengers, and protecting the safety of the driver and passengers.
[0036] In some embodiments of the present invention, refer to the attached Figure 1 and attached Figure 2 As shown, the mounting groove 311 is arranged along the front-rear direction of the vehicle 100 (eg Figure 1 The front end of the suspension assembly 3 is provided with an open mouth 312, and the mounting groove 311 extends along the front and rear direction of the vehicle 100. When assembling the suspension assembly 3, the suspension crushing mechanism 32 is placed in the mounting groove 311 through the open mouth 312, so as to facilitate the installation of the suspension crushing mechanism 32. When the vehicle 100 is subjected to a frontal collision or is in a collision test, the sub-frame assembly 2 is subjected to a frontal collision force, driving the suspension bracket body 31 to move backward, and the power assembly 1 plays a fixing role on the suspension crushing mechanism 32, so that the suspension crushing mechanism 32 is separated from the mounting groove 311 at the open mouth 312, and the connection with the suspension bracket body 31 is disconnected, thereby canceling the indirect connection between the power assembly 1 and the sub-frame assembly 2, so that the sub-frame assembly 2 and the suspension bracket body 31 can continue to move backward without pushing the power assembly 1 to move backward, thereby reducing the collision between the power assembly 1 and the front panel and other structures, improving the score of the vehicle 100 in the collision test, reducing the collision damage suffered by the driver and passengers, and protecting the safety of the driver and passengers.
[0037] In a further embodiment of the present invention, refer to the attached Figure 2As shown, the two inner walls opposite to each other of the mounting groove 311 are provided with guide protrusions 313, and the guide protrusions 313 extend in the front-rear direction. The two opposite side walls of the suspension collapse mechanism 32 are provided with guide grooves 321 cooperating with the guide protrusions 313. Through the cooperation between the guide protrusions 313 and the guide grooves 321, the movement of the suspension collapse mechanism 32 can be guided, so that the suspension collapse mechanism 32 can be easily installed into the mounting groove 311, and the suspension collapse mechanism 32 can be ensured to be separated from the movement direction of the suspension bracket body 31 (refer to the attached Figure 1 front-to-back direction as shown).
[0038] In a specific example, see the attached Figure 2 As shown, the guide protrusion 313 is arranged on the mounting groove 311 along the up and down direction of the vehicle 100 (such as Figure 1 On the two inner walls of the suspension assembly 3, guide grooves 321 are provided on the two side walls of the suspension collapse mechanism 32 along the up-down direction, and the guide grooves 321 extend along the front-back direction and cooperate with the guide protrusions 313, thereby guiding the suspension collapse mechanism 32, facilitating the assembly of the suspension assembly 3 and the movement of the suspension collapse mechanism 32 away from the suspension bracket body 31.
[0039] In a further embodiment of the present invention, refer to the attached Figure 2 As shown, a first connecting hole 322 is provided on the suspension collapse mechanism 32, a second connecting hole is provided on the guide protrusion 313, the first connecting hole 322 is arranged opposite to the second connecting hole, and the suspension assembly 3 also includes a collapse pin 33, which is simultaneously passed through the first connecting hole 322 and the second connecting hole.
[0040] It can be understood that when the vehicle 100 is in a normal state, the crushing pin 33 passes through the suspension crushing mechanism 32 and the suspension bracket body 31 at the same time, which can ensure the connection reliability of the suspension crushing mechanism 32 and the suspension bracket body 31, and ensure the connection stability of the subframe assembly 2, the suspension assembly 3 and the powertrain 1; when the vehicle 100 is subjected to a frontal collision or is in a collision test, the subframe assembly 2 is subjected to the frontal collision force, which drives the suspension bracket body 31 to move backward, and the suspension crushing mechanism 32 is simultaneously subjected to the backward movement force transmitted by the suspension bracket body 31 and the fixing force of the powertrain 1. When the interaction force between the sub-frame assembly 3 and the powertrain 1 reaches a certain level, the crush pin 33 is broken by the force and absorbs part of the collision energy, and the suspension crush mechanism 32 is separated from the mounting groove 311 and disconnected from the suspension bracket body 31, thereby canceling the indirect connection between the powertrain 1 and the sub-frame assembly 2, so that the sub-frame assembly 2 and the suspension bracket body 31 can continue to move rearward without pushing the powertrain 1 to move backward, reducing the collision between the powertrain 1 and structures such as the front panel, improving the score of the vehicle 100 in the collision test, reducing the collision damage to the driver and passengers, and protecting the safety of the driver and passengers.
[0041] It should be noted that by changing the diameter or material of the crush pin 33 , the crush force of the crush pin 33 can be adjusted to meet the requirements of different vehicles 100 .
[0042] In a further embodiment of the present invention, refer to the attached Figure 2 As shown, the second connection holes on each guide protrusion 313 are multiple and spaced apart in the front-to-back direction, and the first connection holes 322 and the crush pins 33 are multiple and correspond to the multiple second connection holes, which can ensure the connection reliability of the suspension crush mechanism 32 and the suspension bracket body 31 from multiple locations, and ensure the connection stability of the subframe assembly 2, the suspension assembly 3 and the power assembly 1. For example, the second connection holes on each guide protrusion 313 can be two, three or four and spaced apart in the front-to-back direction, and the first connection holes 322 and the crush pins 33 are four, six or eight and correspond to the second connection holes.
[0043] In a specific example, see the attached Figure 2 As shown, guide protrusions 313 are provided on both inner walls of the mounting groove 311 in the up-down direction, and the guide protrusions 313 extend in the front-to-back direction. The second connection holes on the two guide protrusions 313 are two spaced apart in the front-to-back direction, and the first connection holes 322 and the collapse column pins 33 are four corresponding to the four second connection holes one by one, which can ensure the connection reliability of the suspension collapse mechanism 32 and the suspension bracket body 31 from all four sides, and ensure the connection stability of the subframe assembly 2, the suspension assembly 3 and the powertrain 1.
[0044] In some embodiments of the present invention, refer to the attached Figure 1 and attached Figure 2 As shown, there are a plurality of mounting grooves 311 arranged at intervals, and a plurality of suspension crushing mechanisms 32 corresponding to the plurality of mounting grooves 311 one by one. The arrangement of a plurality of suspension crushing mechanisms 32 can improve the effect of the suspension crushing mechanisms 32. When the vehicle 100 is in a normal state, the suspension crushing mechanisms 32 are connected to the suspension bracket body 31 from multiple locations, thereby improving the reliability of the connection between the suspension assembly 3 and the powertrain 1. When the vehicle 100 is subjected to a frontal collision or is in a collision test, the plurality of suspension crushing mechanisms 32 are all separated from the mounting grooves 311 and disconnected from the suspension bracket body 31. For example, the mounting grooves 311 may be two, three, four or five arranged at intervals, and the suspension crushing mechanisms 32 may be two, three, four or five corresponding to the mounting grooves 311 one by one.
[0045] In a specific example, see the attached Figure 1 and attached Figure 2As shown, there are three installation grooves 311 arranged at intervals, and there are three suspension collapse mechanisms 32 corresponding to the three installation grooves 311 one by one, so that the suspension assembly 3 can be connected to the power assembly 1 at three locations, thereby improving the reliability of the connection between the suspension assembly 3 and the power assembly 1.
[0046] In some embodiments of the present invention, the suspension crushing mechanism 32 and the mounting groove 311 are transitionally fitted. Compared with the clearance fit, the transition fit can ensure the reliability and stability of the connection between the suspension crushing mechanism 32 and the suspension bracket body 31 of the vehicle 100 under normal conditions; compared with the interference fit, the transition fit can ensure that the suspension crushing mechanism 32 is detached from the mounting groove 311 when the vehicle 100 is subjected to a head-on collision or is in a collision test.
[0047] In some embodiments of the present invention, refer to the attached Figure 1 As shown, the suspension bracket body 31 has a mounting hole 314, and a bushing 315 is arranged in the mounting hole 314. The sub-frame assembly 2 and the suspension bracket body 31 are connected through the connecting member 21, and the connecting member 21 is arranged in the bushing 315, so that the connection mode of the suspension bracket body 31 and the sub-frame assembly 2 is simple and has strong stability, which can ensure the stability and reliability of the connection between the suspension assembly 3 and the sub-frame assembly 2, and avoid the suspension bracket body 31 and the sub-frame assembly 2 from being released when the vehicle 100 moves normally. The setting of the bushing 315 can play the role of sealing and wear protection, ensure the stability of the connecting member 21 connecting the sub-frame assembly 2 and the suspension bracket body 31, and extend the service life of the connecting member 21. Optionally, the connecting member 21 is a bolt.
[0048] In a further embodiment of the present invention, the bushing 315 is interference-fitted with the mounting hole 314 to prevent relative rotation between the bushing 315 and the suspension bracket body 31 , thereby ensuring the reliability of the installation of the bushing 315 .
[0049] In some embodiments of the present invention, refer to the attached Figure 1 and attached Figure 2 As shown, the suspension collapse mechanism 32 is connected to the power assembly 1 through the fastener 11, so that the connection between the suspension collapse mechanism 32 and the power assembly 1 is simple and has strong stability, which can ensure the stability and reliability of the connection between the suspension assembly 3 and the power assembly 1, and avoid the suspension collapse mechanism 32 and the power assembly 1 from being released when the vehicle 100 is running normally. Optionally, the fastener 11 is a bolt.
