Description

Technical Field

[0001] This utility model relates to the field of motor vehicle control levers, and more specifically, to a force-measuring motor vehicle control lever based on a fiber optic sensor. Background Technology

[0002] With the development of motor vehicle technology, people's requirements for vehicle handling performance and safety are constantly increasing. During motor vehicle operation, the operating force of control levers (such as gearshift levers and handbrake levers) is a crucial factor affecting the driving experience and safety. For example, if the shifting force of the gearshift lever is inappropriate, it may lead to uneven shifting, affecting driving comfort, and even delaying shifting opportunities in emergencies, endangering driving safety. The operating force of the handbrake lever is equally critical; too little force may result in poor braking effect, while too much force will cause inconvenience to the driver. Therefore, accurately measuring the force on motor vehicle control levers has become an important aspect of optimizing vehicle control systems, and fiber optic sensors have many unique advantages. First, fiber optic sensors transmit light signals, are unaffected by electromagnetic interference, and can operate stably in the complex electromagnetic environment of a motor vehicle, ensuring the accuracy of measurement data. Second, fiber optic sensors have high sensitivity and accuracy, and can accurately measure minute force changes of the control levers. For example, fiber optic grating sensors can detect strain changes at the nanometer level, corresponding to very high accuracy in force measurement. Furthermore, fiber optic sensors are essentially passive devices, requiring no power supply and eliminating safety hazards such as electrical sparks, thus improving safety in the motor vehicle environment.

[0003] When using existing devices, the joysticks of different body types may be positioned too high or too low, requiring operators to overextend their arms during operation. Over time, this can easily lead to arm fatigue and soreness, especially during long driving periods, where an uncomfortable joystick position can make the driver more prone to fatigue.

[0004] Therefore, it is necessary to redesign the force-measuring vehicle control lever based on fiber optic sensors to address the aforementioned issues. Utility Model Content

[0005] In order to overcome the above-mentioned defects of the prior art, the embodiments of this utility model provide a force-measuring motor vehicle control lever r based on an optical fiber sensor.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A force-measuring motor vehicle control lever based on a fiber optic sensor includes a control lever with two symmetrical slots on its outer wall. Each slot contains a drive device, and the output ends of the two drive devices are fixedly connected to an end cap. A first fixing plate and a second fixing plate are symmetrically arranged on the outer wall of the control lever, and two limiting devices are symmetrically arranged on the second fixing plate. A transmission device is slidably arranged on the outer wall of the control lever, and the output end of the limiting device abuts against the output end of the transmission device.

[0008] like Figure 1-3 As shown, the specific implementation method is as follows: by setting up a drive device, an end cap, a transmission device, etc., the transmission device can drive the drive device to adjust the height of the end cap, so that operators of different body shapes can adjust the height of the end cap according to their needs, thereby preventing excessive arm extension during operation, which would lead to arm fatigue and soreness. By setting up a limiting device, the elastic characteristics of the spring of the limiting device can keep the connecting plate, the connecting rod and the rotating ball against the mounting plate, which can prevent the mounting plate from shaking during the operation of the motor vehicle and affecting the driver's concentration.

[0009] In a preferred embodiment, each of the drive devices includes a threaded rod, which is mounted on the inner bottom wall of a corresponding slot via a bearing. The threaded rod is threadedly connected to a locking block, which is slidably locked in the corresponding slot, and an end cap is fixedly connected to the upper end face of the locking block.

[0010] In a preferred embodiment, each of the limiting devices includes a spring, and the spring is fixedly connected to the lower end face of the second fixed plate. The end of the spring away from the lower end face of the second fixed plate is fixedly connected to a connecting plate. A connecting rod is fixedly installed on the connecting plate, and the top end of the connecting rod passes through the lower end face of the second fixed plate and extends upward. A rotating ball is rotatably installed at the bottom end of the connecting rod, and the rotating ball abuts against the output end of the transmission device.

[0011] In a preferred embodiment, the transmission device includes a mounting plate that is slidably sleeved on the outer wall of the control lever. Two mounting slots are symmetrically formed on the inner wall of the mounting plate, and a rack is fixedly installed in each mounting slot.

[0012] In a preferred embodiment, the outer wall of the mounting plate is provided with a plurality of anti-slip blocks.

[0013] In a preferred embodiment, a gear is fixedly mounted at the bottom end of each of the threaded rods.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] 1. This utility model, by setting up a driving device, an end cap, a transmission device, etc., uses the transmission device to drive the driving device to adjust the height of the end cap, so that operators of different body shapes can adjust the height of the end cap according to their needs, thereby preventing the need to overextend the arm during operation, which would lead to arm fatigue and soreness.

[0016] 2. By setting a limiting device, the elastic characteristics of the spring in the limiting device can make the connecting plate drive the connecting rod and the rotating ball to keep against the mounting plate, which can prevent the mounting plate from shaking during the operation of the motor vehicle and affecting the driver's concentration.

[0017] In summary, this utility model is simple to operate. The transmission device can drive the drive device to adjust the height of the end cap, so operators of different body types can adjust the height of the end cap according to their needs. The elastic characteristics of the spring of the limiting device can keep the connecting plate, the connecting rod and the rotating ball against the mounting plate, which can prevent the mounting plate from shaking during the operation of the motor vehicle and affecting the driver's concentration.

[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. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Reference Figure 1-3The force-measuring motor vehicle control lever based on fiber optic sensors includes a control lever 1. Two slots 11 are symmetrically opened on the outer wall of the control lever 1. Each slot 11 is equipped with a drive device. The output ends of the two drive devices are fixedly connected to an end cap 2. A first fixing plate 3 and a second fixing plate 4 are symmetrically arranged on the outer wall of the control lever 1. Two limiting devices are symmetrically arranged on the second fixing plate 4. A transmission device is slidably arranged on the outer wall of the control lever 1, and the output end of the limiting device abuts against the output end of the transmission device.

[0024] like Figure 1-3 As shown, the specific implementation method is as follows: by setting up a drive device, end cap 2, transmission device and other devices, the transmission device can drive the drive device to adjust the height of the end cap 2, so that operators of different body shapes can adjust the height of the end cap 2 according to their needs, thereby preventing the need to over-extend the arm during operation, which would lead to arm fatigue and soreness. By setting up a limiting device, the elastic characteristics of the limiting device spring 6 can make the connecting plate 7 drive the connecting rod 5 and the rotating ball 8 to keep against the mounting plate 16, which can prevent the mounting plate 16 from shaking during the operation of the motor vehicle and affecting the driver's concentration.

[0025] Each drive device includes a threaded rod 12, which is mounted on the inner bottom wall of the corresponding slot 11 via a bearing. The threaded rod 12 is threadedly connected to a locking block 10, which is slidably locked in the corresponding slot 11. The end cap 2 is fixedly connected to the upper end face of the locking block 10. The rotation of the threaded rod 12 can drive the locking block 10, which is threadedly connected to it, to slide in the slot 11, so that the height of the end cap 2 can be adjusted.

[0026] Each limiting device includes a spring 6, and the spring 6 is fixedly connected to the lower end face of the second fixed plate 4. The end of the spring 6 away from the lower end face of the second fixed plate 4 is fixedly connected to a connecting plate 7. A connecting rod 5 is fixedly installed on the connecting plate 7, and the top end of the connecting rod 5 passes through the lower end face of the second fixed plate 4 and extends upward. A rotating ball 8 is rotatably installed at the bottom end of the connecting rod 5, and the rotating ball 8 abuts against the output end of the transmission device. The natural state of the spring 6 allows the connecting plate 7 to drive the connecting rod 5 and the rotating ball 8 to abut against the upper end face of the mounting plate 16, thereby limiting the mounting plate 16.

[0027] The transmission device includes a mounting plate 16, which is slidably sleeved on the outer wall of the control lever 1. Two mounting slots 14 are symmetrically opened on the inner wall of the mounting plate 16, and a rack 15 is fixedly installed in each mounting slot 14.

[0028] Multiple anti-slip blocks 9 are provided on the outer wall of the mounting plate 16, which can further increase the friction between the operator's hand and the mounting plate 16.

[0029] Each threaded rod 12 has a gear 13 fixedly installed at its bottom end. By pulling the mounting plate 16, the rack 15 on the mounting plate 16 can mesh with the gear 13. By rotating the mounting plate 16, the rack 15 can drive the gear 13 to rotate.

[0030] In use, the mounting plate 16 can be pulled first, and then the mounting plate 16 can slide on the outer wall of the control lever 1. The mounting plate 16 will drive the connecting rod 5 to slide on the second fixed plate 4 through the rotating ball 8. At the same time, the connecting rod 5 will compress the spring 6 through the connecting plate 7 until the rack 15 on the mounting plate 16 meshes with the two gears 13. Then the mounting plate 16 can be rotated. At this time, the rotating ball 8 can rotate on the upper end face of the mounting plate 16. The rotation of the mounting plate 16 can drive the gear 13 meshing with it to rotate synchronously. Then the rotation of the gear 13 can drive the threaded rod 12 fixedly connected to it to rotate synchronously. The rotation of the threaded rod 12 can drive the locking block 10 threadedly connected to it to slide in the locking groove 11. The movement of the locking block 10 can make the end cap 2 move upward. At this time, the height of the end cap 2 can be adjusted, thereby extending the length of the control lever 1.

[0031] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
