In the description of the present invention, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0030] The automobile seat test system provided by the present invention is now described. In the first embodiment, as Figure 1 and Figure 2 As shown, the automobile seat test system includes an adjustable bracket 01, a control operating mechanism 02 and a control module (not shown);

[0031] The bottom of the adjustable bracket 01 is mounted on the cushion of the car seat 05, and the side of the adjustable bracket 01 is mounted on the side of the car seat 05; the control operation mechanism 02 includes a first control operation mechanism 021 and a second control operation mechanism 022, both of which are installed on the side of the adjustable bracket 01, and the adjustable bracket 01 can adjust the positions of the first control operation mechanism 021 and the second control operation mechanism 022, so that the first control operation mechanism 021 and the second control operation mechanism 022 can be arranged on both sides of the control component in different directions, and the different directions include at least one of the longitudinal direction and the oblique direction, as well as the lateral direction; the first control operation mechanism 021 can be extended to drive the control component to move, and the second control operation mechanism can be extended to drive the control component to move, and the extension direction of the first control operation mechanism 021 is opposite to the extension direction of the second control operation mechanism 022; the control module is electrically connected to the control operation mechanism 02, and is used to transmit a control signal to the control operation mechanism 02.

[0032] When debugging the car seat 05, the adjustable bracket 01 is attached to the car seat 05, and the first control operating mechanism 021 and the second control operating mechanism 022 are installed to the target operating position through the adjustable bracket 01. The target operating position allows the first control operating mechanism 021 and the second control operating mechanism 022 to control the control components of the car seat 05.

[0033] It can be understood that the automobile seat 05 test system includes an adjustable bracket 01, a control operating mechanism 02 and a control module. Among them, the adjustable bracket 01 is used to fix the positions of the first control operating mechanism 021 and the second control operating mechanism 022, and the positions of the first control operating mechanism 021 and the second control operating mechanism 022 can be flexibly adjusted. The first control operating mechanism 021 and the second control operating mechanism 022 have the function of operating the control components of the automobile seat 05. Here, the control components of the automobile seat 05 can be buttons or control rods. The moving parts provided by the control operating mechanism 02 can press buttons or toggle control rods. The control module can include a computer device with a computing function. The computer device can be a desktop computer, a laptop computer, or other computing devices. The computer device can be electrically connected to the control operating mechanism 02 through a PCI (Peripheral Component Interconnect, peripheral component interconnection standard) connection line. The control module is electrically connected to the control operating mechanism 02 and can transmit control signals to the control operating mechanism 02.

[0034] In the automobile seat test system provided by the present embodiment, the control operating mechanism 02 can directly act on the control component, and the positions of the first control operating mechanism 021 and the second control operating mechanism 022 can be adjusted by the adjustable bracket 01, so that the first control operating mechanism 021 and the second control operating mechanism 022 can be arranged on both sides of the control component in different directions: when the first control operating mechanism 021 and the second control operating mechanism 022 are arranged on both sides of the control component in the transverse direction, the seat slide rail durability test can be completed; when the first control operating mechanism 021 and the second control operating mechanism 022 are arranged on both sides of the control component in at least one of the longitudinal direction and the oblique direction, at least one of the seat height adjustment durability test and the seat back adjustment durability test can be completed, wherein the first control operating mechanism 021 and the second control operating mechanism 022 are arranged on both sides of the control component in the longitudinal direction for the seat height adjustment durability test, and the first control operating mechanism 021 and the second control operating mechanism 022 are arranged on both sides of the control component in the oblique direction for the seat back adjustment durability test, so that there is no need to design two sets of special test fixtures respectively, thereby reducing the test cost and preparation period.

[0035] The control component includes a first control component 06, which is laterally arranged on the side of the car seat, and a first control operating mechanism 021 and a second control operating mechanism 022 are laterally arranged on both sides of the first control component 06. The first control operating mechanism 021 can be extended to drive the first control component 06 to move toward the rear of the car seat 05, and the second control operating mechanism 022 can be extended to drive the first control component 06 to move toward the front of the car seat 05. The above operation is repeatedly performed until a predetermined number of tests is reached. The first control operating mechanism 021 is extended to drive the first control component 06 to move toward the rear of the car seat 05, which can drive the car seat 05 to move backward along the slide rail; the second control operating mechanism 022 is extended to drive the first control component 06 to move toward the front of the car seat 05, which can drive the car seat 05 to move forward along the slide rail, thereby realizing the slide rail durability test of the car seat 05.

[0036] In the second embodiment, Figure 2As shown, the control component includes a first control component 06, which is horizontally arranged on the side of the car seat, and a first control operating mechanism 021 and a second control operating mechanism 022 are longitudinally arranged on both sides of the first control component 06. The first control operating mechanism 021 can be extended to drive the first control component 06 to rotate clockwise, and the second control operating mechanism 022 can be extended to drive the first control component 06 to rotate counterclockwise. The above operation is repeatedly performed until the predetermined number of tests is reached. The first control operating mechanism 021 is extended to drive the first control component 06 to rotate clockwise, which can drive the car seat 05 to move downward; the second control operating mechanism 022 is extended to drive the first control component 06 to rotate counterclockwise, which can drive the car seat 05 to move upward, thereby realizing the height adjustment durability test of the car seat 05.

[0037] In the third embodiment, Figure 3 As shown, the control component includes a second control component 07, which is tilted on the side of the car seat 05, and a first control operating mechanism 021 and a second control operating mechanism 022 are tilted on both sides of the second control component 07. The first control operating mechanism 021 can be extended to drive the second control component 07 to rotate clockwise, and the second control operating mechanism 022 can be extended to drive the second control component 07 to rotate counterclockwise. The above operation is performed repeatedly until the predetermined number of tests is reached. The backrest of the car seat 05 can be driven to move backward by extending the first control operating mechanism 021 to drive the second control component 07 to rotate clockwise; the backrest of the car seat 05 can be driven to move forward by extending the second control operating mechanism 022 to drive the second control component 07 to rotate counterclockwise, thereby realizing the adjustment durability test of the backrest of the car seat 05.

[0038] In the first embodiment, Figure 1 and Figure 2As shown, the first control operating mechanism 021 and the second control operating mechanism 022 can move in opposite directions synchronously. When the first control operating mechanism 021 is extended, the second control operating mechanism 022 is retracted to keep the second control operating mechanism 022 away from the control component; when the second control operating mechanism 022 is extended, the first control operating mechanism 021 is retracted to keep the first control operating mechanism 021 away from the control component. The above operation is performed repeatedly until the predetermined number of tests is reached. By setting the first control operating mechanism 021 and the second control operating mechanism 022 to move in opposite directions synchronously, when the first control operating mechanism 021 is extended to push the control component to move, the second control operating mechanism 022 can make room for the control component to move, and when the second control operating mechanism 022 is extended to push the control component to move, the first control operating mechanism 021 can make room for the control component to move; at the same time, the first control operating mechanism 021 and the second control operating mechanism 022 move in opposite directions synchronously, which can shorten the extension length of the first control operating mechanism 021 and the second control operating mechanism 022, save the installation space of the test device, and improve the efficiency of manipulating the control component.

[0039] In the first embodiment, Figure 1 and Figure 2 As shown, the first control operating mechanism 021 and the second control operating mechanism 022 can move alternately. When the first control operating mechanism 021 is retracted, the second control operating mechanism 022 is extended so that the second control operating mechanism 022 controls the control component; when the second control operating mechanism 022 is retracted, the first control operating mechanism 021 is extended so that the first control operating mechanism 021 controls the control component. The above operation is performed repeatedly until the predetermined number of tests is reached. After the first control operating mechanism 021 drives the control component to move in the extension direction of the first control operating mechanism 021, the first control operating mechanism 021 is retracted again to make room for the control component to move. After the extension and retraction movement of the first control operating mechanism 021 is completed, the second control operating mechanism 022 is controlled to drive the control component to move in the extension direction of the second control operating mechanism 022, and the second control operating mechanism 022 is retracted again to make room for the control component to move. This control method is relatively simple, and there is no need to perform linkage control on the first control operating mechanism 021 and the second control operating mechanism 022. The simple control method can reduce the probability of control errors.

[0040] In the first embodiment, Figure 1 and Figure 2As shown, the adjustable bracket 01 includes a bracket base 014 and an operating mechanism mounting seat, the bracket base 014 is mounted on the seat cushion of the car seat 05, and the operating mechanism mounting seat is connected to the bracket base 014 and mounted on the side of the car seat; the operating mechanism mounting seat includes a first adjusting component 011 and a second adjusting component 012 arranged horizontally, and a first connecting member 013 and a second connecting member arranged longitudinally, one end of the first connecting member 013 is connected to an end of the first adjusting component 011 close to the front of the car seat 05, the other end of the first connecting member 013 is connected to an end of the second adjusting component 012 close to the front of the car seat 05, one end of the second connecting member is connected to an end of the first adjusting component 011 close to the rear of the car seat 05, and the other end of the second connecting member is connected to an end of the second adjusting component 012 close to the rear of the car seat 05; the first control operating mechanism 021 is installed on the first connecting member 013, and the second control operating mechanism 022 is installed on the second connecting member. The frame structure formed by the first adjusting portion 011, the second adjusting portion 012, the first connecting member 013, and the second connecting member can facilitate adjusting the positions of the first control operating mechanism 021 and the second control operating mechanism 022 according to the position and type of the control component.

[0041] Specifically, the first connecting member 013 is adjustable at the connection position of the first adjusting member 011 and the second adjusting member 012, and the second connecting member is adjustable at the connection position of the first adjusting member 011 and the second adjusting member 012. The first connecting member 013 is provided with a connection slot, and the connection slot is provided with a plurality of first connecting member installation positions; the second connecting member is provided with a connection slot, and the connection slot is provided with a plurality of second connecting member installation positions. These connecting member installation positions can be continuous or discontinuous.

The shapes of the first adjusting member 011, the second adjusting member 012, the first connecting member 013, and the second connecting member can be set according to actual needs. In some examples, the first adjusting member 011 can be an L-shaped long plate, and the second adjusting member 012 and the connecting member 013 can be rod-shaped.

[0042] The support base 014 is provided with a base mounting groove, and the base mounting groove is provided with a plurality of base mounting positions; the first adjustment component 011 is installed on at least one base mounting position by a first fastener.

[0046] When debugging the car seat 05, the adjustable bracket 01 is attached to the car seat 05, so that the adjustable bracket 01 can move with the movement of the car seat 05. The control operating mechanism 02 is adjusted to the vicinity of the control component, that is, the target operation position, through the adjustable bracket 01. At this position, the control operating mechanism 02 can control the control component, thereby improving the accuracy of the control position of the control operating mechanism 02.

[0047] In the fourth embodiment, Figure 1 , Figure 2 and Figure 5As shown, the first control operating mechanism 021 includes a first actuator 21 and a first actuator bracket 22. The first actuator 21 is mounted on the first connecting member 013 through the first actuator bracket 22, and the driving end of the first actuator 22 faces the control component; the second control operating mechanism 022 has the same structure as the first control operating mechanism 021 and is arranged opposite to the first control operating mechanism 021. The second control operating mechanism 022 includes a second actuator and a second actuator bracket, and the driving end of the second actuator faces the control component. The first actuator 21 and the second actuator can be small needle cylinders, and the shapes of the first actuator bracket 22 and the second actuator bracket can be set according to actual needs. The first actuator 21 extends toward the control component to push the control component to move in the extending direction of the first actuator 21, and contracts away from the control component to make room for the control component to move in the extending direction of the second actuator; the second actuator extends toward the control component to push the control component to move in the extending direction of the second actuator, and contracts away from the control component to make room for the control component to move in the extending direction of the first actuator 21; at the same time, the control component is directly controlled by the first actuator 22 and the second actuator, and the structure is simple and the control is convenient.

[0048] In Example 5, Figure 1 , Figure 2 , Figure 6 and Figure 7 As shown, the first control operating mechanism 02 includes a first actuator 21, a first actuator bracket 22, a first actuator connecting member 23, a first push rod 24 and a first sliding bearing 25; the first actuator 21 is mounted on the first connecting member 013 through the first actuator bracket 22; the driving end of the first actuator 21 is connected to the first push rod 24 through the first actuator connecting member 23, and the driving end of the first actuator 21 is away from the control component; the first sliding bearing 25 is arranged on the first actuator bracket 22; the first push rod 24 is inserted into the first sliding bearing 25; the second control operating mechanism 022 has the same structure as the first control operating mechanism 021 and is arranged oppositely, and the second control operating mechanism 022 includes a second actuator, a second actuator bracket, a second actuator connecting member, a second push rod and a second sliding bearing, and the driving component of the second actuator is away from the control component. The first actuator 21 and the second actuator are both electrically connected to the control module. The control module can send control signals to the first actuator 21 and the second actuator. The first actuator 21 drives the first push rod 24 to perform a control operation according to the control signal, and the second actuator drives the second push rod to perform a control operation according to the control signal.

[0049] Specifically, the actuator 21 can be a small needle cylinder. The shape of the first actuator bracket 22 can be set according to actual needs. A circular arc groove is provided at the lower part of the first actuator bracket 22, a semicircular groove and two threaded holes are provided in the middle part of the first actuator bracket 22, a circular through hole is provided at the top of the first actuator bracket 22, and two threaded holes are provided at the front part of the first actuator bracket 22. Among them, at the upper part of the first actuator bracket 22, a fastening bolt can be used to pass through the first connection mounting position and the circular through hole at the top of the first actuator bracket 22; at the lower part of the first actuator bracket 22, a fastening bolt can be used to pass through the first connecting member mounting position and the circular arc groove at the lower part of the first actuator bracket 22, so that the first actuator bracket 22 is fixed on the first connecting member 013.

[0050] The two threaded holes in the middle of the first actuator bracket 22 are used to fix the first actuator 21. The first actuator fixing member 27 can be used to fix the first actuator 21 on the first actuator bracket 22. The first actuator fixing member 27 is a plate with an arc shape in the middle and two circular through holes on the ears at both ends, which correspond to the two threaded holes in the middle of the first actuator bracket. The first actuator 21 can be fixed to the first actuator bracket 22 by tightening the screws and the first actuator fixing member 27.

[0051] The driving end of the first actuator 21 is connected to the first push rod 24 through the first actuator connecting member 23. The first actuator connecting member 23 is a square plate with two circular through holes at both ends, which are connected to the first push rod 24 and the driving end of the first actuator 21 respectively.

[0052] The first sliding bearing 25 is installed on the first actuator bracket 22 through two threaded holes at the front of the first actuator bracket 22. The first sliding bearing 25 can be a sliding ball bearing. The first push rod 24 is inserted into the first sliding bearing 25. The first push rod 24 can move in the first sliding bearing 25 along the axial direction of the first sliding bearing 25.

[0053] The second actuator bracket has the same structure and installation method as the first actuator bracket 22. The first push rod 24 is arranged in parallel with the first actuator 21, so that the first actuator 21 contracts to drive the first push rod 24 to be pushed out, and the first actuator 21 extends to drive the first push rod 24 to be retracted. The second push rod is arranged in parallel with the second actuator, so that the second actuator contracts to drive the second push rod to be pushed out, and the second actuator extends to drive the second push rod to be retracted, which saves more layout space than the method of using the actuator to extend to drive the push rod to be pushed out.

[0054] The first control operating mechanism 021 further includes a first force sensor 26, which is disposed on the first push rod 24; the second control operating mechanism 022 further includes a second force sensor, which is disposed on the second push rod. The first force sensor 26 is electrically connected to the control module, and is used to feed back the force signal of the first push rod 24 to the control module; the second force sensor is electrically connected to the control module, and is used to feed back the force signal of the second push rod to the control module.

[0055] It is understandable that by providing the first force sensor 26 on the first push rod 24 and the second force sensor on the second push rod, the pressure applied by the first push rod 24 and the second push rod to the control component (button or control rod) can be measured. If the pressure is too small, it means that the first push rod 24 and the second push rod cannot accurately operate the control component. At this time, the positions of the first push rod 24 and the second push rod need to be adjusted so that the first push rod 24 and the second push rod are aligned with the control component so that the first push rod 24 and the second push rod can control the control component. If the pressure is too large, it is necessary to reduce the pressure applied by the first push rod 24 and the second push rod in time to prevent the first push rod 24 and the second push rod from damaging the control component.

[0056] The first push rod 24 and the second push rod are both umbrella-shaped structures. The tops of the first push rod 24 and the second push rod are both provided with a support portion 241, and the support portion 241 can resist the control component; the bottoms of the first push rod 24 and the second push rod are provided with mounting holes. The first actuator connecting member 23 is installed on the mounting hole at the bottom of the first push rod through the fourth fastener. The second actuator connecting member is installed on the mounting hole at the bottom of the second push rod through the fourth fastener.

[0057] Understandably, the umbrella-shaped structure of the first push rod 24 and the second push rod includes an opening portion 241 and a rod body. When the control component of the car seat 05 is controlled, the opening portion 241 is against the control component. The opening portion 241 can be circular and have a large area, which can increase the contact area between the first push rod 24 and the second push rod and the control component, reduce the pressure exerted by the first push rod 24 and the second push rod on the control component, and reduce damage to the control component. A mounting hole is provided at the bottom of the rod body. The first actuator connecting member 23 is mounted on the mounting hole at the bottom of the rod body of the first push rod 24 through the fourth fastener, and the second actuator connecting member is mounted on the mounting hole at the bottom of the rod body of the second push rod 24 through the fourth fastener. Here, the fourth fastener can be a fixing screw.

[0058] In the first embodiment, Figure 1As shown, the test system further includes a first position sensor 031 and a second position sensor 032; the first position sensor 031 is arranged on a side of the first control operating mechanism 021 away from the control component, and the first position sensor 031 can output a first position signal; the second position sensor 032 is arranged on a side of the second control operating mechanism 022 away from the control component, and the second position sensor 032 can output a second position signal. The first position sensor 031 and the second position sensor 032 are used to determine the position of the car seat 05; the first position sensor 031 and the second position sensor 032 are electrically connected to the control module.

[0059] For the durability test of the slide rail of the automobile seat 05, the first position sensor 031 is set in front of the automobile seat 05; when the automobile seat 05 is in the front extreme position, the first position sensor 031 is used to feedback the first position signal to the control module; the second position sensor 032 is set behind the automobile seat 05; when the automobile seat 05 is in the rear extreme position, the second position sensor 032 is used to feedback the second position signal to the control module.

[0060] Understandably, the first position sensor 031 is used to sense whether the car seat 05 is in the front limit position, and the second position sensor 032 is used to sense whether the car seat 05 is in the rear limit position. Specifically, the first position sensor 031 is arranged in front of the car seat 05. When the car seat 05 is in the front limit position, the first position sensor 031 generates a first position signal and sends it to the control module. The second position sensor 032 is arranged in the rear of the car seat 05. When the car seat 05 is in the rear limit position, the second position sensor 032 generates a second position signal and sends it to the control module. By setting the first position sensor 031 to detect whether the car seat 05 is in the front limit position, after the second control operating mechanism 022 controls the car seat 05 to reach the front limit position, the first control operating mechanism 021 can be controlled to control the car seat 05 to move backward; by setting the second position sensor 032 to detect whether the car seat 05 is in the rear limit position, after the first control operating mechanism 021 controls the car seat 05 to reach the rear limit position, the second control operating mechanism 022 can be controlled to control the car seat 05 to move backward, thereby accurately controlling the start time of the first control operating mechanism 021 and the second control operating mechanism 022, and controlling the car seat 05 to complete the test of being able to reach the front and rear limit positions.

[0061] For the durability test of the height adjustment of the automobile seat 05, the first position sensor 031 is set above the automobile seat 05, and the second position sensor 032 is set below the automobile seat 05; for the durability test of the backrest adjustment of the automobile seat 05, the first position sensor 031 is set in front of the backrest of the automobile seat 05, and the second position sensor 032 is set behind the backrest of the automobile seat 05.

[0062] Understandably, a position sensor may also be provided near the car seat 05 to sense the position of the car seat 05. At the same time, the position sensor is electrically connected to the control module, and the sensed position data may be fed back to the control module in a timely manner.

[0063] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
