Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of automobile parts, especially to a hip pushing device, which can be applied to the door of an automobile. BACKGROUND

[0002] An automobile door trim is an interior trim panel installed on the front and rear door panel of the passenger compartment area, which mainly functions to shield the panel and the components installed thereon, protect the passengers, and have both aesthetic and functional properties.

[0003] Door trim rigidity design is an important factor for protecting the passengers in a side collision, and the hip pushing block inside the door trim is a countermeasure for most automobile manufacturers to protect passengers in a side collision accident. The hip pushing block, also known as a crash block, is usually installed inside the door trim, and its main function is to absorb and disperse the impact force when a vehicle is involved in a side collision, reduce the injury to the passengers, and push the passengers away from the collision area as soon as possible to achieve the purpose of protecting the passengers.

[0004] In existing products and technologies, the hip pushing block is installed inside the door trim, which is usually a plastic block or a metal bracket to cope with the standard dummy of the New Car Assessment Program (NCAP) organization or regulations, but the weight of the passenger in an actual accident is not equal to that of the dummy. If a person who is heavier than the dummy hits the hip pushing block, the rigidity of the pushing block is not enough to effectively protect the passenger, on the contrary, if a person who is lighter hits the hip pushing block, the rigidity is too large, causing excessive injury to the passenger's hip. There is currently no hip pushing block that can match the weight of the passenger to change the rigidity of the pushing block, which can both avoid the test of the New Car Assessment Program (NCAP) organization and regulations in the early design and match the stable and gentle force to push the passengers away from the collision area when an actual accident occurs.

[0005] Therefore, the hip pushing block in the prior art cannot adjust its rigidity when a vehicle is involved in a side collision accident, which cannot effectively protect the passengers. SUMMARY

[0050] Door trim stiffness design is a crucial factor in protecting occupants in side collisions. Most automakers employ hip thrusters inside the door trim to protect passengers in the event of a side collision. Hip thrusters, also known as anti-collision blocks, are typically installed inside the door trim. Their primary function is to absorb and disperse the impact force when the vehicle is involved in a side collision, minimizing injuries to the occupants. They can also push the occupants away from the collision zone as quickly as possible, thereby protecting their safety.

[0051] In existing products and technologies, the hip thruster is installed inside the door trim, typically as a plastic block or metal bracket. During crash testing, a dummy of a certain weight is typically used to test the hip thruster to determine its stiffness. However, this method results in a fixed stiffness for the hip thruster. When the occupant's weight changes, the hip thruster, while maintaining a constant stiffness, cannot effectively protect the occupant.

[0052] Therefore, the hip push block in the prior art has the problem of being unable to adjust its own stiffness when a vehicle side collision occurs, resulting in an inability to effectively protect the safety of passengers.

[0053] To address the aforementioned issues, the present invention provides a hip thruster device comprising a cushioning assembly mounted on the inside of a vehicle door trim panel, and first and second adjustment assemblies located outside the cushioning assembly and spaced vertically apart. In the event of a side impact, the hip thruster device adjusts its stiffness to accommodate the weight of occupants within the passenger compartment, thereby quickly and steadily pushing the occupant out of the impact zone, thereby protecting the occupant.

[0054] In order to make the purpose, technical solutions and advantages of the present invention more clear, the embodiments of the present invention will be described in further detail below with reference to the accompanying drawings.

[0055] like Figures 1-3 As shown, the overall structure of the hip propulsion device 1 provided in this embodiment is first described.

[0056] This hip thruster 1 comprises a cushioning assembly 30 mounted on the inside of a vehicle door trim panel, and a first adjustment assembly 10 and a second adjustment assembly 20 located outside the cushioning assembly 30 and spaced vertically apart. The first adjustment assembly 10 adjusts the vertical stiffness of the upper region of the cushioning assembly 30, while the second adjustment assembly 20 adjusts the stiffness of the lower region of the cushioning assembly 30. In the event of a side impact, adjusting the stiffness of the cushioning assembly 30 using the first and second adjustment assemblies 10 and 20 allows the occupant to be pushed away from the impact zone earlier with a stable and gentle force, thereby protecting the occupant.

[0057] Optionally, the buffer assembly 30 is installed on the inner side of the door trim panel in the vertical direction, and the side of the buffer assembly 30 close to the interior of the vehicle is flush with the side of the door trim panel close to the interior of the vehicle, thereby ensuring the aesthetics of the door trim panel; and it should be understood that the first adjustment assembly 10 and the second adjustment assembly 20 are also located on the inner side of the door trim panel, and close to the side of the buffer assembly 30 away from the vehicle door.

[0058] Furthermore, the first adjustment assembly 10 includes a first telescopic component 100 and a first lifting mechanism 110. The first telescopic component 100 extends in the vehicle width direction and is vertically movable outside the buffer assembly 30. The first lifting mechanism 110 is located outside the first telescopic component 100 and connected to an end of the first telescopic component 100 that is distal from the buffer assembly 30. Furthermore, an installation gap or abutment exists between the other end of the first telescopic component 100 that is proximal to the buffer assembly 30 and the inner wall surface of the buffer assembly 30. When viewed in the vehicle width direction, the first telescopic component 100 is at least partially located within the upper region of the buffer assembly 30. It should be understood that the first telescopic component 100 being at least partially located within the upper region of the buffer assembly 30 may be located within 1 / 2, 1 / 3, or other portion of the end surface area of ​​the first telescopic component 100 that is proximal to the buffer assembly 30.

[0059] Specifically, the first lifting mechanism 110 can change the position of the first telescopic component 100 in the vertical direction. When the first lifting mechanism 110 drives the first telescopic component 100 to move upward in the vertical direction, the overlapping area of the end face of the other end of the first telescopic component 100 with the upper region of the bumper assembly 30 will decrease, and at the same time, the rigidity of the upper region of the bumper assembly 30 will decrease. When the first lifting mechanism 110 drives the first telescopic component 100 to move downward in the vertical direction, the overlapping area of the other end of the first telescopic component 100 with the upper region of the bumper assembly 30 will increase, and at the same time, the rigidity of the upper region of the bumper assembly 30 will increase.

[0060] Further, the second adjusting assembly 20 comprises a second telescopic component 200 and a second lifting mechanism 210, wherein the second telescopic component 200 extends in the width direction of the vehicle and is vertically movable on the outer side of the bumper assembly 30, the second lifting mechanism 210 is located on the outer side of the second telescopic component 200 and is connected to the end of the second telescopic component 200 away from the bumper assembly 30; and the other end of the second telescopic component 200 close to the bumper assembly 30 has a mounting gap or abuts against the inner wall surface of the bumper, and when viewed in the width direction of the vehicle, the second telescopic component 200 is at least partially located in the lower region of the bumper assembly 30. It should be understood that the second telescopic component 200 at least partially located in the lower region of the bumper assembly 30 can be that the end face region of the other end of the second telescopic component 200 close to the bumper assembly 30 is 1 / 2, 1 / 4, etc.

[0061] Specifically, the second lifting mechanism 210 can change the position of the second telescopic component 200 in the vertical direction. When the second lifting mechanism 210 drives the second telescopic component 200 to move upward in the vertical direction, the overlapping area of the other end of the second telescopic component 200 with the lower region of the bumper assembly 30 will increase, and at the same time, the rigidity of the lower region of the bumper assembly 30 will increase. When the second lifting mechanism 210 drives the second telescopic component 200 to move downward in the vertical direction, the overlapping area of the other end of the second telescopic component 200 with the lower region of the bumper assembly 30 will decrease, and at the same time, the rigidity of the lower region of the bumper assembly 30 will decrease.

[0062] In summary, the working principle of the hip pushing device 1 is as follows:

[0063] When there are passengers in the car and the vehicle is involved in a side collision, the first lifting mechanism 110 can be activated according to the weight of different passengers, driving the first telescopic component 100 to move upward or downward in the vertical direction, changing the vertical position of the first telescopic component 100, thereby changing the overlapping area between the telescopic component and the upper area of ​​the buffer assembly 30; the second lifting mechanism 210 can be activated to drive the second telescopic component 200 to move upward or downward in the vertical direction, changing the vertical position of the second telescopic component 200, thereby changing the overlapping area between the second telescopic component 200 and the lower area of ​​the buffer assembly 30. Through the above two action modes, the supporting force of the first telescopic component 100 and the second telescopic component 200 on the upper and lower areas of the buffer component 300 can be changed, thereby achieving the purpose of changing the stiffness of the buffer assembly 30 to match the weight of different passengers, and ultimately achieving the purpose of pushing the passenger away from the collision area earlier with a stable and gentle force, thereby protecting the passenger's safety.

[0064] Furthermore, in one achievable embodiment, as Figure 1 As shown, in order to facilitate the installation and arrangement of the first adjustment component 10 and the second adjustment component 20, the hip propulsion device 1 provided in this embodiment further includes a base plate 40, wherein the base plate 40 is arranged on the outside of the first adjustment component 10 and the second adjustment component 20 and extends in the vertical direction.

[0065] Specifically, one end of the first lifting structure is installed on the substrate 40, and the other end is connected to the end of the first telescopic component 100 away from the buffer component 300; one end of the second lifting structure is installed on the substrate 40, and the other end is connected to the end of the second telescopic component 200 away from the buffer component 300.

[0066] It should be understood that the base plate 40 can be a rectangular plate, which is installed vertically on the inner side of the door trim panel, located on the side of the buffer assembly 30 away from the vehicle interior space, for installing the first adjustment assembly 10 and the second adjustment assembly 20.

[0067] Furthermore, if Figures 1-3 As shown, the specific structure and setting method of the first adjustment component 10 and the second adjustment component 20 are further explained below.

[0068] First, the structure and arrangement of the first lifting mechanism 110 and the first telescopic component 100 of the first adjustment assembly 10 are described.

[0069] In one possible implementation, Figure 1As shown, the first lifting mechanism 110 includes a first lifting member 1101, a first connecting member 1102 and a first mounting seat 1103 connected in sequence, the first lifting member 1101 is installed on the side of the base plate 40 away from the buffer assembly 30, the first mounting seat 1103 is located on the other side of the base plate 40 close to the buffer assembly 30, and the first mounting seat 1103 has a mounting gap or abuts between the opposite end faces of the base plate 40, and one end of the first connecting member 1102 is fixedly connected to the driving end of the first lifting member 1101, and the other end is fixedly connected to the first mounting seat 1103.

[0070] Further, the first telescopic component 100 includes a plurality of first springs 1001 arranged side by side, one end of the plurality of first springs 1001 is fixedly installed on the side of the first mounting seat 1103 close to the buffer assembly 30 with a spacing in the vertical direction, and the other end extends towards the buffer assembly 30 along the vehicle width direction. It should be understood that the first mounting seat 1103 can be a first mounting plate 1107 arranged in the vertical direction and parallel to the base plate 40, and the first mounting plate 1107 can be arranged as a rectangular plate and fixedly connected with the first connecting member 1102; the number of the plurality of first springs 1001 can be 4, 6, 8, etc.

[0071] Specifically, the plurality of first springs 1001 are fixedly installed on the side of the first mounting seat 1103 close to the buffer assembly 30 with a spacing, and the area surrounded by the plurality of first springs 1001 is optionally rectangular. When the first lifting mechanism 110 drives the first connecting mechanism to drive the first mounting seat 1103 to move upward in the vertical direction, at the same time, the first mounting seat 1103 drives the plurality of first springs 1001 to also move upward in the vertical direction, at this time, as viewed along the width direction of the vehicle, the number of the plurality of first springs 1001 located in the upper region of the buffer assembly 30 will decrease, so that the stiffness of the upper region of the buffer assembly 30 will decrease; when the first lifting mechanism 110 drives the first connecting mechanism to drive the first mounting seat 1103 to move downward in the vertical direction, at the same time, the first mounting seat 1103 drives the plurality of first springs 1001 to also move downward in the vertical direction, as viewed along the width direction of the vehicle, the number of the plurality of first springs 1001 located in the upper region of the buffer assembly 30 will also increase, and at the same time, the stiffness of the upper region of the buffer assembly 30 will increase. Therefore, the plurality of first springs 1001 are used to adjust the stiffness of the upper region of the buffer assembly 30. Since the spring itself has elasticity, when a side collision accident occurs, the people in the vehicle can be pushed away more quickly.

[0072] Furthermore, in order to make the change of stiffness regular during the process of adjusting the stiffness of the upper area of ​​the buffer component 30, the vertical spacing distances between two adjacent first springs 1001 in the multiple first springs 1001 are equal, so that when the first adjustment component 10 is in the process of adjusting the stiffness of the upper area of ​​the buffer component 30, the span of the stiffness change is not very large, and the stiffness value changes linearly and regularly.

[0073] More specifically, the structures and arrangements of the first lifting member 1101 and the first connecting member 1102 are not limited.

[0074] In one possible implementation, Figure 1 As shown, the first lifting component 1101 is a first electric telescopic rod 1104 extending in the vertical direction, the first connecting component 1102 includes a first transmission rod 1105 parallel to the first spring 1001 and a first connecting rod 1106 extending in the vertical direction, and the first mounting seat 1103 is a first mounting plate 1107 arranged parallel to the base plate 40; wherein, the fixed end of the first electric telescopic rod 1104 is fixed to one side of the base plate 40, and along the vertical direction, the driving end of the first electric telescopic rod 1104 extends upward, one end of the first transmission rod 1105 is fixedly connected to the driving end of the first electric telescopic rod 1104, the other end of the first transmission rod 1105 extends toward the buffer assembly 30 and is fixedly connected to the upper end of the first connecting rod 1106, and the lower end of the first connecting rod 1106 is fixedly connected to the upper end of the first mounting plate 1107. Figure 1 In one embodiment, the first connecting member 1102 formed by the first transmission rod 1105 and the first connecting rod 1106 is in an inverted "L" shape.

[0075] It should be understood that the first electric telescopic rod 1104 is installed on the side of the base plate 40 away from the buffer assembly 30, and the first mounting plate 1107 is arranged on the side of the base plate 40 close to the buffer assembly 30. The first connecting member 1102 formed by the first transmission rod 1105 and the first connecting rod 1106 is in an inverted "L" shape to avoid the base plate 40 to achieve a transmission connection between the first electric telescopic rod 1104 and the first mounting plate 1107. This arrangement reduces the space occupied by the first electric telescopic rod 1104 and the first mounting plate 1107 on the inner side of the door trim panel.

[0076] Specifically, when the stiffness of the upper area of ​​the buffer assembly 30 needs to be changed, the first electric telescopic rod 1104 can drive the first transmission rod 1105 to move in the vertical direction and drive the first connecting rod 1106 to move in the vertical direction. At the same time, the first connecting rod 1106 moves in the vertical direction and drives the first mounting plate 1107 to move in the vertical direction, so as to change the number of multiple first springs 1001 located in the upper area of ​​the buffer assembly 30, and ultimately achieve the purpose of changing the stiffness of the upper area of ​​the buffer assembly 30; and, by setting the first lifting component 1101 to adjust the position of the first mounting plate 1107 in the vertical direction along the first electric telescopic rod 1104, it also has the advantage of high adjustment accuracy.

[0077] In another feasible embodiment, the first lifting member 1101 is a first linear motor extending in the vertical direction, the first connecting member 1102 is configured as a first connecting rod parallel to the first spring 1001, the first mounting seat 1103 is configured as a first connecting plate arranged parallel to the substrate 40, and a first strip hole arranged in the vertical direction is opened on the substrate 40; wherein, the fixed end of the first linear motor is fixed to one side of the substrate 40, and along the vertical direction, the driving end of the first linear motor extends upward in the vertical direction, one end of the first connecting rod is fixedly connected to the driving end of the first linear motor, and the other end of the first transmission rod 1105 is directed through the first strip hole and fixedly connected to the first connecting plate.

[0078] Further, if Figures 1-3 As shown, the structure and arrangement of the second lifting mechanism 210 and the second telescopic component 200 of the second adjustment assembly 20 are described below.

[0079] In one feasible embodiment, the second lifting mechanism 210 includes a second lifting member 2101, a second connecting member 2102, and a second mounting seat 2103, which are connected in sequence. The second lifting member 2101 is mounted on a side of the base plate 40 away from the buffer assembly 30, and the second mounting seat 2103 is located on the other side of the base plate 40 close to the buffer assembly 30, with a mounting gap or abutment between the second mounting seat 2103 and the opposite end surface of the base plate 40. In addition, one end of the second connecting member 2102 is fixedly connected to the driving end of the second lifting member 2101, and the other end is fixedly connected to the second mounting seat 2103. It should be understood that the second mounting seat 2103 can be a second mounting plate 2107 arranged in a vertical direction and parallel to the base plate 40, and the second mounting plate 2107 can be set as a rectangular plate and fixedly connected to the second connecting member 2102.

[0080] Furthermore, the second telescopic component 200 includes a plurality of second springs 2001 arranged side by side. One end of each of the plurality of second springs 2001 is fixedly mounted to a side of the first mounting seat 1103 near the buffer assembly 30 at intervals in the vertical direction, and the other end extends along the vehicle width direction toward the buffer assembly 30. It should be understood that the second mounting seat 2103 may be a second mounting plate 2107 arranged vertically and parallel to the base plate 40, and the second mounting plate 2107 may be a rectangular plate fixedly connected to the second connecting member 2102. The plurality of second springs 2001 may be 4, 6, 8, etc.

[0081] Specifically, multiple second springs 2001 are fixedly installed at intervals on the side of the second mounting seat 2103 close to the buffer assembly 30, and the area surrounded by the multiple second springs 2001 can be optionally rectangular. When the second lifting mechanism 210 drives the second connecting mechanism to link the second mounting seat 2103 to move upward in the vertical direction, at the same time, the first mounting seat 1103 drives the multiple second springs 2001 to move upward in the vertical direction. At this time, when viewed along the width direction of the vehicle, the number of the multiple second springs 2001 located in the lower area of ​​the buffer assembly 30 will increase, thereby increasing the stiffness of the lower area of ​​the buffer assembly 30; when the second lifting mechanism 210 drives the second connecting mechanism to link the second mounting seat 2103 to move downward in the vertical direction, at the same time, the second mounting seat 2103 drives the multiple second springs 2001 to move downward in the vertical direction. When viewed along the width direction of the vehicle, the number of the multiple second springs 2001 located in the lower area of ​​the buffer assembly 30 will decrease, and the stiffness of the lower area of ​​the buffer assembly 30 will decrease. Therefore, the stiffness of the lower area of ​​the buffer assembly 30 is adjusted by using multiple second springs 2001. Since the springs themselves are elastic, when a side collision occurs, the occupants of the vehicle can be pushed away more quickly.

[0082] Furthermore, in order to make the change of stiffness regular during the process of adjusting the stiffness of the lower area of ​​the buffer assembly 30, the vertical spacing distances between two adjacent second springs 2001 in the multiple second springs 2001 are equal, so that when the second adjustment assembly 20 is in the process of adjusting the stiffness of the lower area of ​​the buffer assembly 30, the span of the stiffness change is not very large, and the stiffness value changes linearly and regularly.

[0083] Furthermore, the structures and configurations of the second lifting member 2101 and the second connecting member 2102 are not limited.

[0084] In one possible implementation, Figure 1As shown, the second lifting member 2101 is a second electric telescopic rod 2104 extending in the vertical direction, the second connecting member 2102 includes a second transmission rod 2105 parallel to the second spring 2001 and a second connecting rod 2106 extending in the vertical direction, and the second mounting seat 2103 is a second mounting plate 2107 arranged parallel to the base plate 40; wherein, the fixed end of the second electric telescopic rod 2104 is fixed to one side of the base plate 40, and the driving end extends downward in the vertical direction, one end of the second transmission rod 2105 is fixedly connected to the driving end of the second electric telescopic rod 2104, and the other end extends toward the buffer assembly 30 and is fixedly connected to the lower end of the second connecting rod 2106, and the upper end of the second connecting rod 2106 is fixedly connected to the lower end of the second mounting plate 2107. Figure 1 In one embodiment, the first connecting member 1102 formed by the second transmission rod 2105 and the second connecting rod 2106 is in an “L” shape.

[0085] It should be understood that the second electric telescopic rod 2104 is installed on the side of the base plate 40 away from the buffer assembly 30, and the second mounting plate 2107 is arranged on the side of the base plate 40 close to the buffer assembly 30. The first connecting member 1102 formed by the second transmission rod 2105 and the second connecting rod 2106 is in an "L" shape to avoid the base plate 40 to achieve a transmission connection between the second electric telescopic rod 2104 and the second mounting plate 2107. This arrangement reduces the space occupied by the second electric telescopic rod 2104 and the second mounting plate 2107 on the inner side of the door trim panel.

[0086] Specifically, when the stiffness of the lower area of ​​the buffer assembly 30 needs to be changed, the second electric telescopic rod 2104 can drive the second transmission rod 2105 to move in the vertical direction and drive the second connecting rod 2106 to move in the vertical direction. At the same time, the second connecting rod 2106 moves in the vertical direction and drives the second mounting plate 2107 to move in the vertical direction, so as to change the number of multiple second springs 2001 located in the lower area of ​​the buffer assembly 30, and ultimately achieve the purpose of changing the stiffness of the lower area of ​​the buffer assembly 30; and, by setting the second lifting member 2101 to adjust the position of the second mounting plate 2107 in the vertical direction along the second electric telescopic rod 2104, it also has the advantage of high adjustment accuracy.

[0087] In another feasible embodiment, the second lifting member 2101 is a second linear motor extending in the vertical direction, the second connecting member 2102 is configured as a second connecting rod parallel to the second spring 2001, the second mounting seat 2103 is configured as a second connecting plate arranged parallel to the base plate 40, and a second strip hole arranged in the vertical direction is opened on the base plate 40; wherein, the fixed end of the second linear motor is fixed to one side of the base plate 40, and along the vertical direction, the driving end of the second linear motor extends downward in the vertical direction, one end of the second connecting rod is fixedly connected to the driving end of the second linear motor, and the other end of the second transmission rod 2105 is directed through the second strip hole and fixedly connected to the second connecting plate.

[0088] like Figures 1-3 As shown, the specific structure and setting method of the buffer component 30 are further explained below.

[0089] In a feasible embodiment, the buffer assembly 30 includes a buffer component 300 and an installation component 310 arranged in sequence along the width direction of the vehicle, wherein one side of the buffer component 300 is flush with the outer surface of the door trim panel, and is used to buffer the side impact force when a side impact accident occurs, and the installation component 310 is fixed to the inner surface of the buffer component 300 away from the door trim panel, and is used to install the buffer component 300.

[0090] Specifically, the structures and configurations of the buffer component 300 and the mounting component 310 are not limited.

[0091] In a feasible embodiment, since the buffer component 300 will first collide with the hip of the vehicle occupant, the buffer component 300 is configured as a buffer pad 3001 arranged in a vertical direction. The buffer pad 3001 is flexible and can reduce damage to the vehicle occupant.

[0092] Furthermore, the mounting component 310 includes a mounting plate 3101 arranged on the inner surface of the buffer pad 3001 in the vertical direction, for supporting the buffer pad 3001 along the width direction of the vehicle, and a pair of limiting members 3102 arranged at both ends of the mounting plate 3101 in the vertical direction. The mounting plate 3101 and the relative end faces of the buffer pad 3001 are fixedly connected to each other, and a pair of mounting holes are provided on the buffer pad 3001, which are respectively adapted to the pair of limiting members 3102. The pair of limiting members 3102 are respectively embedded in the pair of mounting holes, so that the buffer pad 3001 is limited and fixed by the pair of limiting members to prevent it from slipping in the vertical direction relative to the mounting plate 3101.

[0093] Specifically, the limiting member 3102 may be a limiting rod, a limiting column, etc. Those skilled in the art may set it according to their own needs, and this embodiment does not limit it here.

[0094] Furthermore, in the embodiment disclosed herein, to facilitate control of the travel of the first and second lifting mechanisms 110 and 210, the hip thruster 1 also includes an electronic control module 50, which is mounted on the exterior of the base plate 40 and electrically connected to the first and second lifting mechanisms 110 and 210, respectively. When the vehicle experiences a side collision, the electronic control module 50 receives commands from the vehicle's upper network to accurately control the movement of the first and second lifting mechanisms 110 and 210, thereby driving the movement of the first and second telescopic components 100 and 200, thereby changing the stiffness of the cushioning assembly 30.

[0095] Furthermore, the utility model also discloses a vehicle door, and the aforementioned hip pushing device 1 of the vehicle door; when a side collision accident occurs in the vehicle and the vehicle door is hit, the stiffness of the hip pushing device 1 of the vehicle door can be changed to adapt to the weight of different people in the vehicle passenger compartment, thereby achieving the purpose of pushing the occupants away from the collision area with a stable and gentle force at an earlier stage, thereby achieving the purpose of protecting the safety of the occupants.

[0096] Furthermore, the utility model also discloses a car, comprising the above-mentioned door, an airbag diagnostic control module installed on the car body, a side impact sensor installed on the door and a weight sensor installed on the seat; wherein, the electronic control module 50 is electrically connected to the airbag diagnostic control module and the weight sensor respectively, and the airbag diagnostic control module is electrically connected to the weight sensor and the side impact sensor respectively.

[0097] Specifically, in one case, when a car has a side collision accident and the door is hit, the side collision sensor transmits the collision signal to the airbag diagnostic control module, and the airbag diagnostic control module sends an instruction to the weight sensor to record the passenger weight. At the same time, the airbag diagnostic control module and the weight sensor send instructions to the electronic control module 50. After receiving the signal, the electronic control module 50 calculates the relationship between weight and height, controls the first lifting mechanism 110 to adjust the position of the first telescopic component 100 and the second lifting mechanism 210 to adjust the position of the second telescopic component 200, so as to achieve the purpose of changing the stiffness of the buffer assembly 30 to match the weight of different occupants, and finally achieve the purpose of pushing the occupants away from the collision area earlier with a stable and gentle force, thereby achieving the purpose of protecting the safety of the occupants.

[0098] More specifically, in another case, when the car does not have a side collision accident, the weight sensor directly records the passenger's weight, and the weight sensor sends an instruction to the electronic control module 50. After receiving the signal, the electronic control module 50 calculates the relationship between weight and height, controls the first lifting mechanism 110 to adjust the position of the first telescopic component 100 and the second lifting mechanism 210 to adjust the position of the second telescopic component 200, so as to achieve the purpose of changing the stiffness of the buffer assembly 30 to match the weight of different occupants, and finally adjust the stiffness of the hip thrust device to the appropriate position in advance to achieve the purpose of pre-protecting the safety of the occupants.
