It is also applicable to driving school training, and the coach's instruction deflection scale can be displayed at any time.

[0003] The application number is CN202323080904.3. The utility model discloses a high-precision automobile steering wheel, which relates to the field of automobile steering wheels. In order to solve the problem that the existing steering wheels in the prior art are not provided with a steering reminder device, when the driver starts the vehicle to drive next time, he fails to accurately perceive the direction of the steering wheel, and an accident is likely to occur when the direction is not mastered when driving. The upper and lower ends of the middle of both sides of the inner side of the outer ring of the steering wheel are fixedly connected with a first semicircular limiting protrusion, the upper and lower ends of the middle of both sides of the rear end of the outer ring of the steering wheel are fixedly connected with a second semicircular limiting protrusion, the outer ring of the steering wheel is connected with a C-section wear-resistant patch on both sides, the upper end of the front end of the outer ring of the steering wheel is fixedly connected with a steering reminder, the inner middle of the outer ring of the steering wheel is fixedly connected with a center disk, and the rear end of the upper end of the center disk is fixedly connected with a rotation angle recorder. Summary of the invention

[0004] In view of the deficiencies in the above-mentioned prior art, the present invention aims to provide a direction display device that solves the technical problem of improving the vehicle-mounted steering reminder function, being applicable to driving operations such as moving forward, reversing, and parking, and achieving the display as the vehicle moves.

[0005] In order to solve the above technical problems, the technical solution of the present invention is: a direction display instrument, including a rotating component, a balancing component and a direction display component, the rotating component is connected to the center position of the vehicle steering wheel and rotates synchronously with the vehicle steering wheel, and a circular first direction display component is fixedly connected to the rotating component; the upper part of the balancing component is rotatably connected to the rotating component, and the lower part of the balancing component maintains a vertical downward direction; the direction display component is rotatably connected to the balancing component, and a rotatable circular second direction display component is provided on the direction display component, and the second direction display component and the outer edge of the first direction display component are in non-sliding rolling contact with each other; the second direction display component is connected to a direction display indicating device.

[0006] Furthermore, the rotating part is set as a disk, a first cylinder is vertically fixedly connected to the center of the disk, and the first direction display component is coaxially fixedly connected to the outer end of the first cylinder.

[0007] Furthermore, the first direction display component is configured as a gear.

[0008] Furthermore, a left-right symmetrical direction display symbol is provided on the upper surface of the disc, which is used to display the direction position when the vehicle-mounted steering wheel is turned left or right; the diameter of the disc is 4-6 cm, and the thickness of the disc is 2-5 mm; an instrument seat is provided on the outside of the disc, and the instrument seat is used to facilitate the installation of the direction display instrument at the center position of the vehicle-mounted steering wheel of an existing vehicle. For newly produced vehicles, the direction display instrument can be directly embedded in the vehicle-mounted steering wheel.

[0009] Furthermore, the direction display symbol is set to be luminous.

[0010] Furthermore, a first circular hole is provided in the center of the upper part of the balancing component, and the first circular hole can be rotatably mounted on the first cylinder; balance display panels are provided on both sides of the upper part of the balancing component for displaying that the balancing component is in a balanced position; and a second cylinder is fixedly connected to the lower part of the balancing component.

[0011] Furthermore, the direction display component is configured as a reduction wheel with a rack on the outer edge, a second circular hole is provided at the center of the reduction wheel, the second circular hole is rotatably mounted on the second cylinder, and the rack of the reduction wheel is meshed with the gear.

[0012] Furthermore, the direction display indicating device includes a rotating wheel with a rack on the outer edge and a pointer wheel; the rotating wheel is concentrically fixedly connected to the upper surface of the reduction wheel; the first direction display component is coaxially connected to a third cylinder at one end away from the first cylinder; the pointer wheel core is rotatably mounted on the third cylinder, the pointer wheel is meshed with the outer edge of the rotating wheel, and a pointer is connected to the pointer wheel.

[0013] Furthermore, one tooth is removed from the racks at both ends of the horizontal diameter of the reduction wheel when the direction is returned to the correct position. The reduction wheel must be made into full-circle teeth in order to balance the weight of the gears. All gears are full-circle teeth, but when used on the direction indicator, only half of the circumferential teeth are used. Before the direction indicator system is installed, if the reduction wheel gear still maintains a complete full-circle tooth state, when the system product is rotated countless times, the pointer on the pointer wheel will also rotate countless times, which will mess up the display system of the direction indicator and cannot be restored.

[0014] When producing the reduction wheel, one tooth must not be engraved on both sides of the racks at both ends of the horizontal diameter when the direction is returned to the correct state, even if one tooth is removed. This is to prevent the direction display product from rotating throughout the entire process before installation and use, thereby disrupting the display system.

[0015] Furthermore, rollers that can roll along the circumference of the disc are connected to both sides of the lower part of the balancing component. When the direction display is used on a large vehicle, the downward gravity component of the lower part of the balancing component is small due to the relatively gentle inclination of the steering wheel of the large vehicle. The friction force will cause the balancing component to be unable to swing flexibly and maintain the balance of position. If two rollers are added to both sides of the gravity pendulum at the lower part of the balancing component, the balancing component can swing smoothly and correctly from side to side, so that the balancing component can effectively maintain the balanced position.

[0016] Furthermore, the disc is made of plastic, and the balancing component is made of metal.

[0017] The technical solution of the present invention is a vehicle-mounted left-right deviation indicator, also known as a direction indicator. The shape is set to be a perfect circle. Its volume is set to be equivalent to the size and thickness of an ordinary pocket watch. The present invention is made into a diameter of 4-6cm and a disc thickness of 2-5mm, which is equivalent to the diameter of an ordinary pocket watch and the thickness of a watch.

[0018] The technical solution of the present invention can be displayed using a three-stage five-digit scale display: 0 degrees is the direction return; 0.5 degrees is a half-turn deviation; 1.0 degrees is a 1-turn deviation (false return); 1.5 degrees is a 1.5-turn deviation (full direction deviation). Micro-scale internal push. The direction display does not need to be connected to a power source and can be displayed intuitively in a luminous manner. The method of use of the present invention is: embed or stick the direction display in the center of the vehicle steering wheel so that it rotates synchronously with the vehicle steering wheel, and it can be used, track with the wheel, and the meter moves when the wheel moves. It can be intuitively interpreted according to the displayed instructions without additional instructions.

[0019] The beneficial effects of the application of the technical solution of the present invention are: it can improve the operating function of the vehicle steering wheel, and can be applied to the vehicle's forward, reverse, parking and other operations, and can achieve the display of the vehicle at any time. It can also be applied to driving school training, and the coach's instruction deflection scale can be displayed at any time.

[0028] Embodiment 1:

[0029] like Figures 1 to 5As shown, a direction display instrument comprises a rotating component 1, a balancing component 2 and a direction display component 3.

The second direction display component 3 is connected to a direction display indicating device.

[0030] The technical solution of the present invention is used by embedding or pasting the vehicle-mounted direction indicator in the center of the vehicle-mounted steering wheel so that it can be used by synchronously rotating with the vehicle-mounted steering wheel.

It can be used forever in one car without the impact of fault locking. It is small in size and can be intuitively interpreted.

[0031] Embodiment 2:

[0032] like Figures 1 to 5 As shown, based on the technical solution of the first embodiment, the technical solution of the present invention is preferred, the rotating part 1 is set as a disk, the center of the disk is vertically fixedly connected with a first cylinder 1011, and the first direction display component 101 is fixedly connected to the outer end of the first cylinder 1011.

[0033] Preferably, the first direction display member 101 is a gear. A left-right symmetrical direction display symbol is provided on the upper surface of the disc, which is used to display the direction position when the vehicle steering wheel is turned left or right, and the display symbol is set to be luminous. The technical solution of the present invention shows that a half-circle symbol 102, a full-circle symbol 103, a half-circle symbol 105 and a direction return symbol 104 can be set.

[0034] The technical solution of the present invention can be displayed using a three-stage five-digit scale display: 0 degrees is the direction return; 0.5 degrees is a half-turn deviation; 1.0 degrees is a 1-turn deviation (false return); 1.5 degrees is a 1.5-turn deviation (full direction deviation). Micro-scale internal push. The direction display does not need to be connected to a power supply and adopts an intuitive luminous display. The usage of the present invention is: embed or stick the vehicle-mounted direction display to the center of the vehicle-mounted steering wheel so that it can be used synchronously with the vehicle-mounted steering wheel, track with the wheel, and the meter moves when the wheel moves. It can be intuitively interpreted according to the displayed instructions without additional instructions.

[0035] Preferably, the diameter of the disc is 4-6 cm, and the thickness of the disc is 2-5 mm. The technical scheme of the present invention is called a direction display instrument, which is a vehicle-mounted left and right deviation display instrument. The shape is set to be a perfect circle. Its volume is set to be equivalent to the size and thickness of an ordinary pocket watch. The present invention is made into a diameter of 4-6 cm, and the thickness of the disc is 2-5 mm, that is, it is equivalent to the diameter of an ordinary pocket watch and the thickness of a watch.

[0036] Preferably, an instrument seat is provided outside the disc, and the instrument seat is used to facilitate the installation of the direction indicator at the center of the vehicle-mounted steering wheel of an existing vehicle. For newly produced vehicles, the direction indicator can be directly embedded in the vehicle-mounted steering wheel.

[0037] Embodiment three:

[0038] like Figures 1 to 5 As shown, based on the technical solutions of the above embodiments, the technical solutions of the present invention are preferred, wherein a first circular hole 201 is provided at the center of the upper portion of the balancing component 2, the first circular hole 201 is rotatably mounted on the first cylinder 1011, and is located on the inner side of the first direction display component 101; balance display panels 203 are provided on both sides of the upper portion of the balancing component 2 for displaying that the balancing component 2 is in a balanced position; and a second cylinder 202 is fixedly connected to the lower portion of the balancing component 2.

[0039] Preferably, the direction display component 3 is configured as a reduction wheel with a rack on the outer edge, and a second circular hole 301 is provided in the center of the reduction wheel. The second circular hole 301 is rotatably mounted on the second cylinder 202, and the rack of the reduction wheel is meshed with the gear. A direction display indicator line or a direction display indicator needle is provided on the reduction wheel. The direction display indicator line is an indicator line set on the diameter of the reduction wheel. The direction display indication of the technical solution of the present invention can be displayed by a pointer or by a semicircular diameter indicator line. The pointer display is clear and easy to understand, and easy for users to accept, while the semicircular diameter indicator line display has a low cost.

[0040] Preferably, the direction display indicating device includes a rotating wheel 302 with a rack on the outer edge and a pointer wheel 303; the rotating wheel 302 is concentrically fixedly connected to the upper surface of the reduction wheel; the first direction display component 101 is coaxially connected to a third cylinder 1012 at one end away from the first cylinder 1011; the pointer wheel 303 core is rotatably mounted on the third cylinder 1012, the pointer wheel 303 is meshed with the outer edge of the rotating wheel 302, and a pointer 304 is connected to the pointer wheel 303.

[0041] Preferably, one tooth is removed from the racks at both ends of the horizontal diameter of the reduction wheel when the direction is returned to the correct state. The reduction wheel must be made into full-circle teeth in order to balance the weight of the gear. All gears are full-circle teeth, but when used on the direction indicator, only half of the circumferential teeth are used. Before the direction indicator system is installed, if the reduction wheel gear still maintains a complete full-circle tooth state, when the system product is rotated countless times, the pointer on the pointer wheel will also rotate countless times, which will mess up the display system of the direction indicator and cannot be restored.

[0042] When manufacturing the reduction wheel, the racks at both ends of the horizontal diameter in the direction of the return state must be prohibited from engraving one tooth, even if one tooth is removed, to prevent the direction indicator product from rotating throughout the entire process before installation and use, thereby causing the display system to be messed up. The prohibition of engraving one tooth means that one tooth is removed from each end of the diameter of the reduction wheel, so that the display system of the direction indicator only rotates within the range of one half of the circle gear and will not rotate to the other half of the circle gear, thus preventing the display system from being messed up. And the purpose of preventing the display system from being messed up can be achieved by simply prohibiting engraving on the reduction wheel.

[0043] Preferably, the disc is made of plastic, and the balancing component 2 is made of metal.

[0044] Embodiment 4:

[0045] like Figures 1 to 5 As shown, based on the technical solution of the above embodiment, the technical solution of the present invention is preferably that the lower two sides of the balancing component 2 are connected with rollers that can roll along the circumference of the disc.

[0046] When the direction indicator of the technical solution of the present invention is used on a large vehicle, the downward gravity component of the lower part of the balancing component 2 is small due to the relatively gentle inclination of the steering wheel of the large vehicle, and the friction force causes the balancing component 2 to be unable to swing flexibly to maintain the balance of position. If two rollers are installed on both sides of the gravity pendulum at the lower part of the balancing component 2, the balancing component 2 can be naturally swung left and right smoothly and accurately, so that the balancing component 2 can effectively maintain the balanced position. Since the steering wheel of a small vehicle is installed at a relatively steep angle, the balancing component 2 of the direction indicator of the technical solution of the present invention can be effectively used without rollers. The direction indicator of the present invention needs to be equipped with auxiliary rollers for the direction display of large vehicles to achieve a more effective use purpose.

[0047] The beneficial effects of the application of the technical solution of the present invention are: it can improve the operating function of the vehicle steering wheel, and can be applied to the vehicle's forward, reverse, parking and other operations, and can achieve the display of the vehicle at any time. It can also be applied to driving school training, and the coach's instruction deflection scale can be displayed at any time. In addition, the material of the technical solution of the present invention can be made of all-metal and semi-metal, which is low in cost, simple to make, and worry-free to wear. One car can be used forever, and there is no trouble locking. It is small in size and can be intuitively interpreted.

[0048] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
