Description

TECHNICAL FIELD

[0001] The utility model relates to vehicle detection related technical field especially vehicle steering operation force measuring tool. BACKGROUND

[0002] When the driver rotates the steering wheel, the steering wheel drives the steering shaft to rotate. The steering shaft transmits the torque to the steering gear, and the steering gear transmits the torque to the steering tie rod after amplifying or adjusting through a series of mechanical or hydraulic, electric devices. The steering tie rod pushes the wheel knuckle of the wheel to make the wheel rotate around the kingpin, so as to change the driving direction of the vehicle. In this process, the force exerted by the driver on the steering wheel is the steering operation force.

[0003] Most of the existing vehicle steering operation force measuring tools have a pullable sliding plate in the device shell. One end of the shell and one end of the sliding plate are connected with a fixed component. When in use, the sliding plate is pulled out, the clamping component is attached to both sides of the steering wheel, the sliding plate is loosened, and under the action of the spring, the sliding plate slides into the device shell, so as to fix the device on the steering wheel. However, this device is usually used for circular steering wheels. With the increasing variety of existing cars, steering wheels also come in a variety of shapes, not just circular. The clamping of this device on non-circular steering wheels may not be very stable, which may lead to inaccurate test results to some extent. UTILITY MODEL CONTENT

[0004] The utility model aims at solving the shortcomings in the prior art and provides a vehicle steering operation force measuring tool.

[0005] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme:

[0006] The vehicle steering operation force measuring tool comprises a shell, a spring connected in the shell, a block connected to one end of the spring, the block and the shell being in sliding connection, a rod connected to one end of the block and the shell, two groups of connecting pieces movably penetrating one end of the two groups of rods, a column connected to one end of the connecting pieces, a nut in threaded connection with a threaded portion formed on one end of the two groups of rods, a torque sensor rotatably connected to one end of the block, and a display unit arranged on one end of the shell.

[0007] Preferably, the block is connected with a stopper at one end.

[0008] Preferably, the outer wall of one end of the column is sleeved with a rubber ring.

[0009] Preferably, the display unit is in threaded connection with a bolt at one end and the other end, and the two groups of bolts are in threaded connection with the shell.

[0010] Preferably, one end of the two groups of bolts is connected with a knob.

[0011] Preferably, one end of each of the multiple sets of nuts is connected to a washer.

[0012] Preferably, the outer wall of the torque sensor is fitted with an anti-slip ring.

[0013] The beneficial effects of this utility model are as follows:

[0014] 1. By coordinating the nuts, connectors, and columns, tightening the nuts removes the restriction on the connectors, allowing them to rotate. Depending on the shape of the steering wheel, rotating the connectors adjusts their angle, thereby adjusting the position of the columns. This makes multiple sets of columns fit more closely to the outer surface of the steering wheel. After adjustment, rotating the nuts pushes one set of connectors, and continuing to rotate pushes another connector against the housing, thus restricting the connector's rotation. Pulling the block allows multiple sets of columns to fit against both sides of the steering wheel. Releasing the block allows the columns to press against the steering wheel under spring pressure, thus fixing the equipment to the steering wheel. By rotating the connectors, the equipment can be fixed to steering wheels of various shapes to a certain extent, improving the accuracy of the test results.

[0015] 2. Through the cooperation between the housing, column and stop, after the test is completed, the steering wheel is removed from the equipment. When the block retracts into the housing under the action of the spring, the stop will contact the housing first, limiting the spring from continuing to pull the block. This avoids the connection parts from colliding with the housing and causing damage to the connection parts to a certain extent. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] Example 1, referring to Figures 1 to 5 A vehicle steering force measuring tool includes a housing 1, with a spring 2 connected inside the housing 1. The spring 2 applies a force to a block 3, causing it to move towards the inner cavity of the housing 1. One end of the spring 2 is connected to the block 3, which is slidably connected to the housing 1. Both the block 3 and the housing 1 have rods 4 connected to one end. Two sets of connecting parts 5 are movably connected to one end of each set of rods 4. The connecting parts 5 rotate and adjust their angles to make the column 6 fit more closely to the outer surface of the steering wheel. One end of each set of connecting parts 5 is connected to the column 6. Nuts 7 are threaded at one end of each set of rods 4. Rotating the nut 7 pushes one set of connecting parts 5 into contact with the other set. Continuing to rotate the nut 7 until one set of connecting parts 5 is in contact with the housing 1, at which point the two sets of connecting parts 5 are fixed, restricting rotation. One end of the body 3 is rotatably connected to a torque sensor 10. By rotating the torque sensor 10, the steering force of the vehicle can be detected. One end of the housing 1 is provided with a display unit 13, which includes a display screen and a component for receiving electrical signals emitted by the torque sensor 10. This is existing technology and will not be described in detail here. Rotating the connecting piece 5 adjusts its own angle and also adjusts the position of the column 6, making the column 6 fit more closely to the outer surface of the steering wheel. Picking up the device and pulling the block 3 makes multiple sets of columns 6 fit with the corresponding positions of the steering wheel. Releasing the block 3 causes it to retract under the action of the spring 2, causing multiple sets of columns 6 to press against the steering wheel. To a certain extent, it can provide relatively stable clamping for steering wheels of more shapes, which improves the accuracy of the detection results to a certain extent.

[0024] In this embodiment, a stop block 12 is connected to one end of the block 3. After the test is completed, the device is removed. Under the action of the spring 2, when the block 3 moves towards the inside of the housing 1, the stop block 12 will first contact the connecting piece 5 with the housing 1, which to a certain extent avoids the problem of damage caused by the connecting piece 5 colliding with the housing 1. Rubber rings 8 are fitted on the outer walls of one end of multiple sets of columns 6 to increase the friction with the steering wheel and improve the clamping stability to a certain extent. Bolts 14 are threaded to one end and the other end of the display unit 13. Both sets of bolts 14 are threaded to the housing 1, allowing the display unit 13 to be accessed. A knob 15 is connected to one end of each set of bolts 14, making it easier to rotate the bolts 14. Washers 9 are connected to one end of multiple sets of nuts 7 to a certain extent, preventing the nuts 7 from rubbing against the connecting piece 5 during rotation and causing damage. An anti-slip ring 11 is fitted on the outer wall of the torque sensor 10, allowing for more stable rotation of the torque sensor 10 and preventing inaccurate test results due to factors such as hand sweat.

[0025] The working principle of this embodiment is as follows: During use, rotate nut 7 to remove the restriction on connector 5. Rotate connector 5 according to the shape of the steering wheel to be tested, so that multiple sets of pillars 6 are in contact with the steering wheel. After adjustment, rotate nut 7, and washer 9 pushes one set of connectors 5. Continue rotating nut 7 to drive connector 5 to push another set of connectors 5 until they are pressed against the housing 1, restricting the rotation of connector 5. Pick up the device and pull block 3. After multiple sets of pillars 6 are in contact with the steering wheel, release block 3. Under the action of spring 2, pillars 6 press against the steering wheel, fixing the device on the steering wheel. By rotating the connector... The connector 5 can relatively stably fix the device on steering wheels of various shapes, which improves the accuracy of the test results to a certain extent. Rotating the torque sensor 10, the torque sensor 10 transmits an electrical signal to the display unit 13. The test value of the vehicle steering force can be viewed on the display screen on the display unit 13. After the test is completed, pull the block 3 to remove the device. Release the block 3, and under the action of the spring 2, the block 3 retracts into the housing 1. The stop block 12 will contact the housing 1 before the connector 5, which to a certain extent avoids the housing 1 from colliding with the connector 5 and causing damage.

[0026] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
