[0001] The utility model belongs to the technical field of simulation racing cars, and particularly relates to a thumb dial component for a simulation racing car. Background Art

[0002] In the existing simulation racing car system, the dial plays a key role and can transmit information such as engine braking and brake balance. The dial is usually located on the steering wheel close to the driver's fingers, allowing the driver to turn it in the fastest and most comfortable posture. However, the common existing dial structures often cannot meet the driver's tactile requirements. Content of the Utility Model

[0003] Aiming at the above problems existing in the prior art, the purpose of the utility model is to provide a thumb dial component for a simulation racing car. By setting the dial as a gear-like structure and cooperating with a sphere and an elastic member, the dial has a good tactile feeling for turning. By adjusting the extending length of the set screw or replacing the elastic member and / or the sphere, the tactile feeling for turning the dial can be adjusted. The set screw is screwed into the through hole, and the adjustment and disassembly are convenient.

[0004] In order to achieve the above purpose, the technical solution adopted by the utility model is as follows:

[0005] A thumb dial component for a simulation racing car includes a dial, a sphere, an elastic member, a signal converter and a PCB circuit board installed on the steering wheel of the simulation racing car. The dial is rotatably installed on the steering wheel handle of the racing car. A plurality of grooves are evenly spaced along the circumferential surface of the dial. The sphere can be pushed into a groove on the circumference of the dial under the pressure of the elastic member and restrict the movement of the dial. When the dial is driven to rotate by an external force, the sphere is pushed out of the groove by the protrusion between two adjacent grooves. The signal converter receives the rotation information of the dial and transmits the information to the PCB circuit board connected to the signal converter.

[0006] As a further improvement of the above technical solution:

[0007] An installation cavity for installing the thumb dial component is provided on the steering wheel handle. The dial is rotatably installed in the installation cavity. A through hole communicating with the installation cavity is provided on the steering wheel handle. The sphere and the elastic member are located in the through hole.

[0008] The thumb dial component further includes a set screw. The sphere, the elastic member and the set screw are in contact in sequence. The inner wall of the through hole is provided with internal threads, and the set screw is screwed into the through hole.

[0009] The thumb dial component further includes a dial box lid and a bolt. The dial box lid covers the opening of the installation cavity and is fastened to the steering wheel handle by the bolt. There is a notch on the dial box lid for exposing the upper half of the dial.

[0010] The signal converter is an encoder, and the PCB circuit board is electrically connected to the control system of the simulation racing car.

[0011] The dial wheel is rotatably mounted on the steering wheel handle through a supporting shaft, the dial wheel is fixedly sleeved on the supporting shaft, the supporting shaft is rotatably mounted on the steering wheel handle, and one end of the supporting shaft is connected to the signal converter.

[0012] The sphere is a small ball made of metal, and the elastic part is a spring.

[0013] The dial wheel includes a dialing part for being dialed by fingers and a limiting part for allowing the ball to enter. The dialing part and the limiting part are fixedly connected. The limiting part is provided with a plurality of grooves evenly spaced along a circumference. When the dial wheel rotates, a part of the ball is pushed into each groove of the limiting part in turn.

[0014] The thumb wheel assembly can be detachably mounted on the steering wheel handle as an independent module.

[0015] The beneficial effects of the utility model are:

[0016] (1) By setting the dial wheel as a gear-like structure and cooperating with a ball and an elastic member, the dial wheel has a better dialing feel. The dialing feel of the dial wheel can be adjusted by adjusting the insertion length of the top screw or replacing the elastic member and / or the ball.

[0023] The specific implementation of the present invention is described in detail below in conjunction with the accompanying drawings. It should be understood that the specific implementation described here is only used to illustrate and explain the present invention, and is not used to limit the present invention.

[0024] For ease of description, spatially relative terms such as "above", "above", "on the upper surface of", "above", etc. may be used here to describe the spatial positional relationship between a device or feature and other devices or features as shown in the figure. It should be understood that spatially relative terms are intended to include different orientations of the device in use or operation in addition to the orientation described in the figure. For example, if the device in the accompanying drawings is inverted, the device described as "above other devices or structures" or "above other devices or structures" will be positioned as "below other devices or structures" or "below other devices or structures". Thus, the exemplary term "above" can include both "above" and "below". The device can also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatially relative descriptions used here are interpreted accordingly.

[0025] A thumb wheel assembly for a simulated racing car, such as Figures 1 to 4 As shown, it includes a support shaft 13, a shaft support 8, a dial box housing 9, a dial wheel 5, a sphere 10, an elastic member 11, a top screw 12, a signal converter 7, a PCB circuit board 6, a dial box cover 3, and a bolt 4.

[0026] The steering wheel handle 1 of the simulated racing car comprises a handle frame 2 and a rubber sleeve sleeved on the handle frame 2. The handle frame 2 is provided with an installation cavity for installing the thumb wheel assembly.

[0027] The thumbwheel 5 is rotatably mounted in the mounting cavity. Specifically, the thumbwheel 5 is mounted in the mounting cavity via a support shaft 13 and a shaft support 8. The shaft support 8 includes a bearing and a sealing ring. The support shaft 13 passes through the center of the thumbwheel 5. The thumbwheel 5 is fixedly sleeved on the support shaft 13, that is, the support shaft 13 and the thumbwheel 5 rotate synchronously. Both ends of the support shaft 13 are rotatably supported on the handle frame 2 via the shaft support 8 respectively. It should be noted that one end or both ends of the support shaft 13 can also be rotatably supported on the thumbwheel box housing 9 via the shaft support 8. The thumbwheel box housing 9 can be regarded as an auxiliary component that facilitates the installation and support of the various components of the thumbwheel assembly.

[0028] Dial 5 Figure 2 As shown in or 4, it includes a toggle portion 51 and a limiting portion 52, and the toggle portion 51 and the limiting portion 52 are coaxially fixedly connected, that is, the toggle portion 51 and the limiting portion 52 are fixedly sleeved on the support shaft 13, and the toggle portion 51 and the limiting portion 52 are arranged along the length direction of the support shaft 13.

[0029] The toggle portion 51 is provided with a plurality of grooves evenly spaced along a circumference, forming a gear-like structure, and the protrusions between two adjacent grooves are teeth. The structure of the limiting portion 52 is similar to that of the toggle portion 51, and is also provided with a plurality of grooves evenly spaced along a circumference.

[0030] A through hole 14 connected to the installation cavity is provided on the handle frame 2. The outlet of the through hole 14 is located at the bottom surface of the installation cavity. A ball 10, an elastic member 11, and a top screw 12 are placed in sequence in the through hole 14. The ball 10, the elastic member 11, and the top screw 12 are in contact with each other in sequence. The ball 10 is closer to the dial 5 than the elastic member 11. An internal thread is provided on the inner wall of the through hole 14, and the top screw 12 can be screwed into the through hole 14. The elastic member 11 is in a compressed state. Under the pressure of the elastic member 11, a part of the ball 10 can enter a groove on the circumference of the limiting part 52 of the dial 5, and the other part remains in the through hole 14. The groove and the through hole 14 are aligned. At this time, the ball 10 can limit the rotation of the dial 5. When the thumbwheel 5 is driven to rotate by an external force, the ball 10 is pushed by the teeth between two adjacent grooves of the limiting portion 52, and the ball 10 is pushed out of the groove under the action of the pushing force, and the ball 10 re-enters the through hole 14, and the elastic member 11 is compressed. When the teeth of the limiting portion 52 of the thumbwheel 5 are aligned with the through hole 14, the teeth of the limiting portion 52 contact the ball 10 and align to apply a force, and the ball 10 is confined in the through hole 14. When the thumbwheel 5 rotates until the next groove of the limiting portion 52 is aligned with the through hole 14, the ball 10 is partially pushed into the groove under the action of the elastic member 11.

[0031] In this embodiment, the ball 10 is a small ball made of metal material, and the elastic member 11 is a spring.

[0032] By adjusting the length of the top screw 12 extending into the through hole 14, the compression amount of the elastic member 11 can be adjusted, thereby adjusting the hand feeling when the finger moves the moving part 51 of the dial wheel 5. The hand feeling when the finger moves the dial wheel 5 can also be adjusted by replacing the elastic member 11 and / or the ball 10.

[0033] The signal converter 7 is an encoder or a band switch. In this embodiment, the signal converter 7 is an encoder.

[0034] In this embodiment, the signal converter 7 is connected to the PCB circuit board 6. The signal converter 7 is also connected to one end of the support shaft 13, and one end of the support shaft 13 is connected to the rotating part of the signal converter 7. The support shaft 13 drives the rotating part to rotate synchronously, and the rotation information of the rotating part is used as the signal input of the signal converter 7. The signal converter 7 transmits the rotation information of the dial wheel 5 it receives to the PCB circuit board 6, and the PCB circuit board 6 transmits the information to the main board or the control system and realizes the preset or real-time adjustment of various parameters of the racing car. In other words, the signal of the rotation of the dial wheel 5 is generated and transmitted by the signal converter 7. Preferably, the cross-section of one end of the support shaft 13 connected to the signal converter 7 is hexagonal. The technical solution of the encoder converting the rotation information into an electrical signal is a prior art and will not be repeated here. The PCB circuit board 6 is mounted on the dial box housing 9 or the handle frame 2.

[0035] The dial box cover 3 covers the opening of the installation cavity and is fastened to the handle frame 2 by bolts 4. The dial box cover 3 has a notch for exposing the upper half of the dialing part 51 of the dial wheel 5 for easy finger dialing.

[0036] In addition, a shell can be provided, which is detachably mounted on the handle frame 2, and the mounting cavity, through hole 14 and the thumb wheel assembly are all arranged on the shell, that is, the thumb wheel assembly is detachably mounted on the handle frame 2 or other required positions as an independent module.

[0037] Based on the above structure, the working principle and process of the utility model are as follows: the competitor's finger moves the moving part 51 of the dial wheel 5, and due to the action of the ball 10, the dial wheel 5 can only rotate step by step, that is, during the rotation of the dial wheel 5, the ball 10 enters each of the grooves of the limiting part 52 in sequence, and when the ball 10 enters the groove, a part of it enters the groove and the other part remains in the through hole 14, and a part of the ball 10 is periodically pushed into the groove by the elastic member 11 and withdrawn from the groove into the through hole 14. The signal converter 7 detects the rotation direction and number of steps of the dial wheel 5, and transmits the above rotation information to the PCB circuit board 6, and the PCB circuit board 6 transmits the information to the control system of the simulated racing car, and the control system makes corresponding feedback according to the received rotation information of the dial wheel 5 and the built-in program.

[0038] Finally, it is necessary to explain here that the above embodiments are only used to further illustrate the technical solution of the utility model in detail and cannot be understood as limiting the protection scope of the utility model. Some non-essential improvements and adjustments made by technicians in this field based on the above content of the utility model belong to the protection scope of the utility model.
