[0029] To make the objectives, technical solutions and advantages of the embodiments of the present utility model clearer, the technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Apparently, the described embodiments are some but not all of the embodiments of the present utility model.

[0030] As Figure 1 and Figure 2 shown, this embodiment provides a force sensor wheel steering control tester, which includes a base 1, a mounting seat 2 rotatably arranged on the surface of the base 1, a counterweight arranged at the bottom of the mounting seat 2, and a measuring instrument 3 arranged on the mounting seat 2. It also includes a fixing mechanism and a locking mechanism. The fixing mechanism is arranged inside the base 1 and is used to mount the base 1 on the steering wheel. The locking mechanism is arranged on the mounting seat 2 and is used to automatically fix the measuring instrument 3 when the measuring instrument 3 abuts against the mounting seat 2.

[0031] When it is necessary to test the steering of the steering wheel, first abut the measuring instrument 3 against the mounting seat 2. The locking mechanism provided can automatically fix the measuring instrument 3 and the mounting seat 2, with simple operation and time saving. Then, the fixing mechanism provided can stably fix the base 1 on steering wheels of different specifications and sizes, thereby preventing the detection device from falling off the steering wheel. The counterweight provided can keep the mounting seat 2 and the measuring instrument 3 in a horizontal state all the time. Therefore, when the steering wheel is rotated, the steering data can be tested through the measuring instrument 3.

[0032] As Figure 2 and Figure 5As shown, as a preferred embodiment, on the basis of the above method, further, an installation groove 101 is provided in the middle of the base 1, and sliding grooves 102 are provided on both sides inside the base 1. The fixing mechanism includes a knob 4 rotatably provided on the top of the base 1, a sliding plate 6 slidably provided inside the sliding grooves 102 on both sides of the base 1, a fixing hook 7 provided at one end of the sliding plate 6 away from the base 1, a screw rod 5 rotatably provided on the inner wall of the installation groove 101 and threadedly connected to the sliding plate 6, a driving bevel gear 401 provided at one end of the knob 4 located inside the installation groove 101, and a driven bevel gear 501 provided on the screw rod 5 located inside the installation groove 101 and meshed with the driving bevel gear 401;

[0033] Rotating the knob 4 can drive the driving bevel gear 401 to rotate. The driving bevel gear 401 will drive the two screw rods 5 provided with the driven bevel gear 501 to rotate. The two screw rods 5 will then drive the sliding plates 6 on both sides of the base 1 to move and slide out of the sliding grooves 102 inside the base 1. According to needs, first move the fixing hooks 7 on the sliding plates 6 to both sides of the steering wheel, and then reverse the knob 4 to drive the sliding plates 6 to move in the reverse direction, thereby being able to drive the fixing hooks 7 to move in the reverse direction and abut against the outer wall of the steering wheel, so as to be able to stably clamp the base 1 and the measuring instrument 3 on steering wheels of different specifications and sizes. Compared with the prior art in which the device is clamped on the steering wheel by the elastic force of a spring, the solution of the present application can improve the stability of fixing the base 1 and prevent the base 1 and the measuring instrument 3 from falling off the steering wheel.

[0034] As Figure 2 、 Figure 6 and Figure 7 shown, as a preferred embodiment, on the basis of the above method, further, a cavity 701 is provided inside the fixing hook 7. A rotating shaft 8 penetrating the cavity 701 is rotatably connected to the top of the fixing hook 7. A binding strap 9 is wound around the rod wall of the rotating shaft 8 inside the cavity 701. One end of the binding strap 9 away from the rotating shaft 8 passes through the side wall of the fixing hook 7 and extends outward;

[0035] A connecting head 10 is provided at one end of the binding strap 9 located outside the fixing hook 7. A T-shaped fixing plug 1001 is provided on the side wall of the connecting head 10. A T-shaped fixing groove 601 matching the fixing plug 1001 is provided on the surface of the sliding plate 6. A torsion spring 801 is also sleeved on the rod wall of the rotating shaft 8 located outside the fixing hook 7;

[0036] After the base 1 is clamped to the steering wheel by the fixing hook 7, the strap 9 inside the fixing hook 7 can be drawn out, and the fixing plug 1001 on the connecting head 10 can be pressed into the T-shaped fixing groove 601 on the inner wall of the sliding plate 6. It should be noted that the fixing plug 1001 can be made of rubber or plastic. Therefore, the fixing plug 1001 will deform when it contacts the T-shaped fixing groove 601, which facilitates the staff to forcibly press the fixing plug 1001 into the T-shaped fixing groove 601 to fix the connecting head 10. Thus, the strap 9 can be used to tie the side of the steering wheel away from the fixing hook 7, further improving the stability of the fixation of the base 1. When the fixing plug 1001 on the connecting head 10 is pulled out of the T-shaped fixing groove 601, the torsion spring 801 will be released from the force and drive the rotating shaft 8 to reverse, and then the strap 9 can be wound up again.

[0037] Among them, the inner surface of the fixing hook 7 is provided with uniformly distributed anti-slip grooves 702; by providing the anti-slip grooves 702, the friction between the fixing hook 7 and the steering wheel can be increased, thereby further improving the stability of the clamping between the fixing hook 7 and the steering wheel.

[0038] As Figure 4 shown, as a preferred embodiment, on the basis of the above method, further, the locking mechanism includes fixing sleeves 11 provided on both sides of the mounting seat 2, a clamping block 12 slidably disposed inside the fixing sleeve 11, and a first spring 1201 disposed between the clamping block 12 and the inner wall of the fixing sleeve 11. A fixing cavity 201 adapted to the measuring instrument 3 is provided on the surface of the mounting seat 2;

[0039] A pulling block 13 is slidably connected to the side wall of the fixing sleeve 11, and a pulling rope 1301 is connected between one end of the pulling block 13 located inside the fixing sleeve 11 and the end face of the clamping block 12;

[0040] Press the measuring instrument 3 against the fixing cavity 201 on the surface of the mounting seat 2. When the measuring instrument 3 contacts the clamping block 12, the clamping block 12 will be first pushed into the fixing sleeve 11 and the first spring 1201 will be compressed. After the measuring instrument 3 is completely inserted into the fixing cavity 2, the first spring 1201 will be released from the force and drive the clamping block 12 to pop out of the fixing sleeve 11. At this time, the clamping block 12 will contact the surfaces on both sides of the measuring instrument 3, thereby being able to block the measuring instrument 3 and fix the measuring instrument 3 in the fixing cavity 201. Therefore, when the measuring instrument is placed in the fixing cavity 201, the measuring instrument 3 can be automatically fixed. When the measuring instrument 3 needs to be disassembled, only need to pull the pulling rope 1301 through the pulling block 13, and pull the clamping block 12 back into the fixing sleeve 11 through the pulling rope 1301. At this time, the clamping block 12 is separated from the measuring instrument 3, so that the loosened measuring instrument 3 can be taken out of the fixing cavity 201, and the operation is simple and time-saving.

[0041] As Figure 3As shown, as a preferred embodiment, on the basis of the above method, further, on both sides of one end of the mounting base 2 facing the base 1, there are fixed cylinders 14. Inside the fixed cylinders 14, there is a sliding connection with a sliding rod 1401 that passes through the mounting base 2 and extends into the interior of the fixed cavity 201. A second spring 1402 is connected between the sliding rod 1401 and the inner bottom wall of the fixed cylinder 14. One end of the sliding rod 1401 located inside the fixed cavity 201 is connected with a push plate 15;

[0042] When the measuring instrument 3 is inserted into the fixed cavity 201, the measuring instrument 3 will also squeeze the push plate 15, causing the push plate 15 to drive the sliding rod 1401 to slide into the fixed cylinder 14 and compress the second spring 1402. When the latch 12 is pulled back into the fixed sleeve 11 by the pulling rope 1301 and the measuring instrument 3 is released, the second spring 1402 will be released from the force and drive the sliding rod 1401 to rebound and reset. At this time, the push plate 15 will also instantaneously rebound to eject the measuring instrument 3 from the fixed cavity 201, thereby being able to improve the speed of disassembling the measuring instrument 3.

[0043] The working principle of the present utility model: When it is necessary to test the steering of the steering wheel, the measuring instrument 3 is pressed against the fixed cavity 201 on the surface of the mounting base 2. When the measuring instrument 3 contacts the latch 12, it will first squeeze the latch 12 into the fixed sleeve 11 and compress the first spring 1201. After the measuring instrument 3 is completely inserted into the fixed cavity 201, the first spring 1201 will be released from the force and drive the latch 12 to pop out of the fixed sleeve 11. At this time, the latch 12 will contact the surfaces on both sides of the measuring instrument 3 to block and fix the measuring instrument 3. Therefore, when the measuring instrument 3 is placed in the fixed cavity 201, the measuring instrument 3 can be automatically fixed, and the operation is simple and time-saving. At this time, rotating the knob 4 can drive the driving bevel gear 401 to rotate. The driving bevel gear 401 will drive two lead screws 5 provided with driven bevel gears 501 to rotate. The two lead screws 5 will drive the sliding plates 6 on both sides of the base 1 to move and slide out of the chute 102 inside the base 1. According to the need, first move the fixed hooks 7 on the sliding plates 6 to both sides of the steering wheel, and then reverse the rotation of the knob 4 to drive the sliding plates 6 to move in the reverse direction, thereby being able to drive the fixed hooks 7 to move in the reverse direction and abut against the outer wall of the steering wheel, so as to stably clamp the base 1 and the measuring instrument 3 on steering wheels of different specifications and sizes, preventing the base 1 and the measuring instrument 3 from falling off the steering wheel. By setting the counterweight block, the mounting base 2 and the measuring instrument 3 can always be in a horizontal state. Therefore, when the steering wheel is rotated, the steering data can be tested through the measuring instrument 3.

[0044] The above embodiments are only used to illustrate the present invention rather than limit the technical solutions described in the present invention. Although the present specification has described the present invention in detail with reference to the above embodiments, the present invention is not limited to the above specific embodiments. Therefore, any modification or equivalent replacement of the present invention; and all technical solutions and their improvements that do not depart from the spirit and scope of the invention are covered within the scope of the claims of the present invention.
