[0041] Referring to Figure 1 、 Figure 2 and Figure 4 , the present utility model provides an automobile throttle opening control device, comprising:

[0042] The support member 1 has an adjustable length. The two ends of the support member 1 are respectively a first end 11 and a second end 12;

[0043] The fixing structure 2 is hinged to the first end 11. The fixing structure 2 includes a fixing seat 21. The fixing seat 21 is formed with a fixing groove 211. The fixing groove 211 is used to accommodate the front end a1 of the seat cushion of the vehicle seat a and is arranged through the fixing seat 21 along the length direction of the front end a1 of the seat cushion. And,

[0044] The clamping structure 3 is hinged to the second end 12. The clamping structure 3 is formed with a clamping groove 31 and a guide groove 3321. The clamping groove 31 is used to be adapted to the accelerator pedal b1. The guide groove 3321 penetrates through the groove side wall of the clamping groove 31 opposite to the second end 12 and penetrates through the notch 311 of the clamping groove 31. The guide groove 3321 is used for the connecting rod b2 connected to the lower end of the accelerator pedal b1 to pass through.

[0045] When using the throttle opening control device, the front end a1 of the seat cushion is clamped in the fixing groove 211, so that the fixing seat 21 is fixed to the vehicle seat a; the notch 311 of the clamping groove 31 is corresponded to the rear end of the accelerator pedal b1, and the clamping structure 3 is pushed forward. The accelerator pedal b1 is clamped in the clamping groove 31, and the connecting rod b2 is limited in the guide groove 3321, so that the clamping structure 3 is fixed to the accelerator pedal b1. Then, the length of the support member 1 is adjusted to adjust the opening degree of the accelerator pedal b1. And the first end 11 and the second end 12 are respectively hinged to the fixing seat 21 and the clamping structure 3. Thus, when adjusting the length of the support member 1, it does not affect the connection stability between the fixing seat 21 and the front end a1 of the seat cushion, and the clamping structure 3 and the accelerator pedal b1. Thus, the throttle opening control device can replace the driver to step on the accelerator to control the opening degree of the throttle, so as to meet the NVH jitter test of the vehicle at different throttle opening degrees, and other performance tests of the vehicle when a stable throttle opening is required, and avoid the discomfort of the driver stepping on the accelerator for a long time. In this way, the structure is simple, the manufacturing cost is low, and it is flexible, convenient and has good versatility.

[0046] Specifically, referring to Figures 1 to 3 , in this embodiment, the fixing structure 2 further includes a limiting member 22 and an elastic member 23. The limiting member 22 extends along the depth direction of the fixing groove 211. The middle part of the limiting member 22 is hinged to the groove side wall of the fixing groove 211. The limiting member 22 includes a limiting portion extending out of the fixing groove 211 from the middle part thereof, and a pressing portion extending into the fixing groove 211 from the middle part thereof; the two ends of the elastic member 23 are respectively connected to the pressing portion and the corresponding groove side wall of the fixing groove 211.

[0047] Continue to refer toFigures 1 to 3 When the front end a1 of the cushion is received in the fixing groove 211, the front end a1 of the cushion will press the pressing portion, pressing the pressing portion to move close to the groove side wall of the corresponding fixing groove 211, thereby driving the limiting portion to move away from the groove side wall of the corresponding fixing groove 211, that is, rotating towards the inside of the fixing groove 211 to abut against the upper side or the lower side of the front end a1 of the cushion. In this way, the connection is more stable and firm, reducing the influence on the test results due to the shaking of the fixing structure 2.

[0048] In addition, the arrangement of the elastic member 23 restricts the movement of the limiting member 22 during the fixing process of the front end a1 of the cushion and the fixing seat 21, avoiding random shaking of the limiting member 22 and facilitating the installation and fixing of the fixing groove 211 and the front end a1 of the cushion.

[0049] Specifically, there is no limitation on the arrangement of the elastic member 23. In this embodiment, the elastic member 23 can be arranged as a spring or a rubber rod.

[0050] There is no limitation on the shape of the limiting member 22, as long as it abuts against the upper side or the lower side of the front end a1 of the cushion when the front end a1 of the cushion is received in the fixing groove 211. In this embodiment, referring to Figure 3 ,the limiting member 22 is arranged in an arc shape bent towards the inside of the fixing groove 211, so that when the fixing structure 2 is fixed to the front end a1 of the cushion, the limiting member 22 can tightly abut against the upper side and the lower side of the front end a1 of the cushion, making it more firm.

[0051] There is no limitation on the number of the limiting member 22 and the elastic member 23. In order to further improve the connection stability, in this embodiment, the limiting assembly is arranged in two, and the two limiting members 22 are respectively arranged on two opposite groove side walls of the fixing groove 211. The elastic member 23 is arranged in two, and one ends of the two elastic members 23 are respectively on two opposite groove side walls of the fixing groove 211, and the other ends are respectively connected to the two pressing portions correspondingly. Thus, when the front end a1 of the cushion is received in the fixing groove 211, the two limiting portions jointly clamp the upper and lower sides of the front end a1 of the cushion. In this way, the fixing is more stable, and the cushion is of a flexible setting, and the disassembly and assembly are simple and easy to operate.

[0052] Furthermore, in this embodiment, referring to Figure 2 、 Figure 4 and Figure 5, the clamping structure 3 includes a plate body 32 and a clamping member 33. One side surface of the plate body 32 is hinged to the second end 12; the clamping member 33 includes a connecting piece 331 and a clamping piece 332. The connecting piece 331 extends along the thickness direction of the plate body 32, and one end of it is connected to the side surface of the plate body 32 facing away from the second end 12. The clamping piece 332 is connected to the other end of the plate body 32 and is arranged opposite to the plate body 32; the clamping groove 31 is formed between the clamping piece 332 and the plate body 32; the guide groove 3321 is arranged on the clamping piece 332. Thus, when the accelerator pedal b1 is fixed to the clamping structure 3, the accelerator pedal b1 is clamped between the clamping piece 332 and the plate body 32. In this way, the structure is simple and the cost is low.

[0053] Furthermore, the clamping piece 332 is arranged as a metal thin sheet. Since the metal thin sheet has a certain elasticity, the clamping groove 31 can accommodate accelerator pedals b1 of more sizes, improving the versatility of the clamping structure 3, and can also clamp the accelerator pedal b1 more tightly.

[0054] It should be noted that the thickness of the accelerator pedal b1 installed in the clamping groove 31 cannot exceed the elastic limit of the metal thin sheet.

[0055] In this embodiment, referring to Figure 4 and Figure 5 , at least part of the end of the clamping piece 332 facing away from the connecting piece 331 is inclined in a direction away from the plate body 32. Thus, the height of the clamping groove 31 near its notch 311 is greater than the height of the middle part of the clamping groove 31, facilitating the installation of the accelerator pedal b1 into the clamping groove 31.

[0056] In this embodiment, referring to Figure 1 , Figure 2 and Figure 5 , the support member 1 includes a sleeve 13 and two connecting rods 14. The inner hole of the sleeve 13 is arranged as a threaded hole; each connecting rod 14 includes a threaded rod section 141 and a hinged rod section 142 connected to each other. The two threaded rods are respectively screwed to both ends of the sleeve 13, and the two hinged rod sections 142 are respectively hinged to the fixed seat 21 and the clamping structure 3. The length of the support member 1 can be adjusted by the length of the two threaded rod sections 141 screwed to the sleeve 13 to increase or decrease the supporting force, thereby controlling the size of the accelerator opening. The structure is simple and the operation is convenient.

[0057] In another embodiment, the support member 1 can be arranged as a hydraulic cylinder. The cylinder seat of the hydraulic cylinder and the free end of the driving rod are respectively hinged to the fixed seat 21 and the plate body 32, and the driving rod expands and contracts to adjust the length of the support member 1.

[0058] There is no limitation on the structure in which the two articulated rod segments 142 are articulated to the fixed seat 21 and the plate body 32, as long as it can enable the fixed seat 21 and the plate body 32 to rotate around an axis extending radially along the support member 1. In this embodiment, with reference to Figure 5 , the vehicle throttle opening control device includes a plurality of articulated structures 4. Each articulated structure 4 includes an articulated seat 41 and a rotating shaft 42. The articulated seat 41 is provided on the end face of the fixed seat 21 facing away from the fixed groove 211 or on one side face of the plate body 32, and the articulated seat 41 is formed with two rotating shaft 42 holes that both extend radially along the support member 1, and the two rotating shaft 42 holes are spaced apart radially along the support member 1. Both ends of the rotating shaft 42 are rotatably connected to the two rotating shaft 42 holes respectively, and the middle part of the rotating shaft 42 is for connecting each articulated rod segment 142.

[0059] In addition, the articulated structure 4 can also be provided on the groove side wall of the fixed groove 211, so that the limiting member 22 is rotatably connected to the fixed seat 21.

[0060] Specifically, in this embodiment, the spiral directions of the threads of the two threaded rod segments 141 are arranged in opposite directions. Thus, by rotating the sleeve 13, the two connecting rods 14 can be moved away from or close to each other. After the fixed structure 2 is fixed to the vehicle seat a and the clamping structure 3 is fixed to the accelerator pedal b1, the length of the support member 1 can be adjusted multiple times to control the supporting force and the throttle opening size. In this way, the operation is simplified, the accuracy of the vehicle performance test is guaranteed, and the labor intensity of the operators is reduced.

[0061] The above are only the preferred embodiments of the present invention, and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
