Description

Technical Field

[0001] This utility model relates to the field of driver assistance technology, and in particular to a wheel alignment indicator. Background Technology

[0002] Many drivers, especially new drivers, often encounter a frustrating problem while driving: it's difficult to determine whether the front wheels are straight after turning the steering wheel. This can easily lead to safety hazards—for example, misjudging the direction when driving straight can cause the vehicle to veer off course, potentially resulting in a traffic accident; or failing to straighten the wheels when parking can damage the steering system over time and affect directional control the next time you start driving.

[0003] However, existing wheel alignment indicator devices have some shortcomings: for example, the prompts are not intuitive enough, making it difficult for drivers to judge the current orientation of the wheels at a glance; the installation method is fixed and lacks adjustment function, which can hinder drivers from using the horn and other operations; in addition, the structure is complex and the reliability is not high, affecting its practicality. Utility Model Content

[0004] In view of this, the present invention provides a wheel alignment indicator that clearly displays the direction of the front wheels and allows for adjustment of the relative position and / or angle between the wheel alignment indicator and the steering wheel.

[0005] To achieve the above objectives, the technical solution of this utility model embodiment is implemented as follows:

[0006] This utility model provides a wheel centering indicator, mounted on a steering wheel. The wheel centering indicator includes: a housing with a receiving cavity and a display area; an indicator gear and a gravity gear, both rotatably mounted within the receiving cavity, the indicator gear meshing with the gravity gear, an indicator portion formed on the indicator gear corresponding to the display area, and a gravity portion at the lower part of the gravity gear, the gravity portion always ensuring that the indicator portion is within the projection plane of the display area towards the indicator portion; and a connecting assembly connected to the housing to adjust the relative position and / or angle between the wheel centering indicator and the steering wheel.

[0007] According to this utility model, the wheel centering indicator achieves a clear display of the front wheel direction by cooperating with the indicator part on the indicator gear and the display area on the housing. By setting a gravity part on the gravity gear, gravity automatically keeps the indicator part pointing upward. By setting a connecting component, the relative position of the wheel centering indicator and the steering wheel can be adjusted, and / or the angle between the wheel centering indicator and the steering wheel can be adjusted. It is compatible with various steering wheels. The overall structure of the wheel centering indicator is simple, stable and reliable.

[0008] In one possible implementation of this utility model, the tooth ratio between the indicator gear and the gravity gear is 10:1.

[0009] Thus, when the gravity gear rotates one revolution, the indicator gear rotates 36°; when the gravity gear rotates two revolutions, the indicator gear rotates 72°. This visually reduces the steering wheel rotation angle, making it easier for the driver to observe and improving the sensitivity and practicality of the wheel alignment indicator. It allows the driver to quickly determine whether the front wheels are aligned or the angle of rotation of the front wheels.

[0010] In one possible implementation of this utility model, a first bearing seat and a second bearing seat are formed in the receiving cavity. An indicator bearing is sleeved on the first bearing seat, and an indicator gear is sleeved on the indicator bearing. A gravity bearing is sleeved on the second bearing seat, and a gravity gear is sleeved on the gravity bearing.

[0011] In this way, by using the bearing and bearing housing to cooperate, the frictional resistance when the gravity gear and the indicator gear rotate is reduced, and the sensitivity is improved. By setting the bearing housing, a limiting function is played, which limits the stability and reliability of the meshing of the gravity gear and the indicator gear, and prevents the gear from deviating or jamming. Setting the first bearing housing and the second bearing housing reduces wear and extends the service life of the wheel return indicator.

[0012] In one possible implementation of this utility model, the display area is provided with five indicator points, and a limiting post is provided on each side of the display area, the limiting post being located within the receiving cavity.

[0013] In this way, the five indicator points make it easy for the driver to quickly judge the direction and angle of the front wheel rotation, thereby helping the driver to quickly judge whether the steering wheel is straight. A limit post is set on each side of the display area to prevent the indicator gear from rotating excessively, avoid the indicator part from exceeding the visible range, limit the rotation angle of the indicator gear to be too large, and protect the indicator gear and gravity gear from overload damage.

[0014] In one possible implementation of this utility model, the outer shell includes an upper shell and a lower shell, the upper shell and the lower shell together defining the receiving cavity, the first bearing seat is formed on at least one of the upper shell and the lower shell, and the second bearing seat is formed on at least one of the upper shell and the lower shell.

[0015] Thus, the separate outer shell facilitates the assembly of internal components. The upper and lower shells make it easier to assemble gears and bearings into the receiving cavity, improving assembly efficiency and reducing production costs. At the same time, it facilitates maintenance. If a component is damaged, separating the upper and lower shells will expose the component inside the receiving cavity, reducing the maintenance difficulty of the wheel return indicator.

[0016] In one possible implementation of this utility model, the connecting assembly includes: a mounting base, a telescopic rod, and a gripper. The mounting base is connected to the lower housing, one end of the telescopic rod is hinged to the mounting base, and the gripper is hinged to the other end of the telescopic rod.

[0017] Thus, the telescopic rod allows for adjustment of the relative position between the wheel alignment indicator and the steering wheel. The height of the wheel alignment indicator or its horizontal distance from the driver can be adjusted by extending the telescopic rod. Multiple hinges allow for adjustment of the angle between the wheel alignment indicator and the steering wheel. By adjusting the relative rotation angle between the telescopic rod and the mounting base and / or the relative rotation angle between the telescopic rod and the gripper, the display area of ​​the wheel alignment indicator can be kept directly facing the driver's eyes, facilitating observation and improving vehicle driving safety.

[0018] In one possible implementation of this utility model, the upper housing has a first connecting portion, the lower housing has a second connecting portion, and the upper housing and the lower housing are connected by the first connecting portion and the second connecting portion.

[0019] In this way, the connection stability between the upper and lower housings is improved by the cooperation of the first and second connecting parts, preventing the connection between the upper and lower housings from loosening or falling off, and improving the overall rigidity of the housing. While ensuring the structural strength of the housing, damage to the wheel return indicator is avoided, making assembly and maintenance easier and reducing the assembly and maintenance difficulty between the upper and lower housings.

[0020] In one possible implementation of this utility model, one of the first connecting portion and the second connecting portion is formed as a protrusion, and the other of the first connecting portion and the second connecting portion is formed as a groove, with the protrusion extending into the groove.

[0021] In this way, the connection between the upper and lower housings is simplified by the cooperation of the protrusions and grooves, thereby reducing the difficulty of connecting the upper and lower housings, simplifying the connection steps, improving the assembly and maintenance efficiency of the upper and lower housings, and reducing production and maintenance costs.

[0022] In one possible implementation of this utility model, the first connecting part includes a plurality of first connecting parts, which are arranged at intervals in the circumferential direction of the upper housing; the second connecting part includes a plurality of second connecting parts, which are arranged in a one-to-one correspondence with the plurality of first connecting parts.

[0023] In this way, by setting multiple first connecting parts and correspondingly arranged multiple second connecting parts, multi-point connection between the upper shell and the lower shell is realized, which enhances the overall rigidity of the shell, prevents the upper shell and the lower shell from falling off or moving, and the one-to-one arrangement facilitates the quick positioning and installation of the upper shell and the lower shell, thus improving the assembly convenience.

[0024] In one possible implementation of this utility model, the wheel alignment indicator further includes a seal disposed between the upper housing and the lower housing.

[0025] Thus, the sealing element prevents dust from entering the receiving cavity, avoiding affecting gear operation and preventing impurities from causing wear on the gears. The sealing element also provides waterproofing, ensuring dryness inside the receiving cavity, preventing moisture from corroding the gears, and extending the service life of the wheel return indicator.

[0040] Many drivers, especially new drivers, often encounter a frustrating problem while driving: it's difficult to determine whether the front wheels are straight after turning the steering wheel. This can easily lead to safety hazards—for example, misjudging the direction when driving straight can cause the vehicle to veer off course, potentially resulting in a traffic accident; or failing to straighten the wheels when parking can damage the steering system over time and affect directional control the next time you start driving.

[0041] However, existing wheel alignment indicator devices have some shortcomings: for example, the prompts are not intuitive enough, making it difficult for drivers to judge the current orientation of the wheels at a glance; the installation method is fixed and lacks adjustment function, which can hinder drivers from using the horn and other operations; in addition, the structure is complex and the reliability is not high, affecting its practicality.

[0042] In view of this, the present invention provides a wheel alignment indicator that is clear in display, flexible in installation, simple and reliable in structure, and helps to improve driving safety and convenience.

[0043] It should be noted that the vehicles or automobiles mentioned in this utility model can refer to large automobiles, small automobiles, special-purpose vehicles, etc. For example, according to the vehicle type, the vehicles or automobiles in this utility model can be sedans, off-road vehicles, multi-purpose vehicles (MPVs), or other types of vehicles.

[0044] The following is for reference. Figures 1-6 The present invention describes a wheel alignment indicator 100 according to an embodiment of the present invention. The wheel alignment indicator 100 includes: a housing 1, an indicator gear 2, a gravity gear 3, and a connecting assembly 4.

[0045] Specifically, the wheel alignment indicator 100 is mounted on the steering wheel. A receiving cavity 13 is formed inside the housing 1, and a display area 113 is formed on the housing 1. The indicator gear 2 and the gravity gear 3 are rotatably mounted in the receiving cavity 13. The indicator gear 2 meshes with the gravity gear 3. An indicator part 21 is formed on the indicator gear 2. The indicator part 21 is arranged correspondingly to the display area 113. A gravity part 31 is provided at the lower part of the gravity gear 3. The gravity part 31 always keeps the indicator part 21 in the projection plane of the display area 113 toward the indicator part 21. The connecting component 4 is connected to the housing 1 to adjust the relative position and / or angle between the wheel alignment indicator 100 and the steering wheel. Thus, by cooperating with the indicator part 21 on the indicator gear 2 and the display area 113 on the housing 1, the function of clearly displaying the direction of the front wheels is realized. By setting a gravity part 31 on the gravity gear 3, gravity automatically keeps the indicating direction of the indicator part 21 always upward. By setting a connecting component 4, the relative position of the wheel centering indicator 100 and the steering wheel can be adjusted, and / or the angle between the wheel centering indicator 100 and the steering wheel can be adjusted. It is compatible with various steering wheels. The overall structure of the wheel centering indicator 100 is simple, stable and reliable.

[0046] It is understood that a receiving cavity 13 is formed inside the outer casing 1 to accommodate components and protect the indicator gear 2 and the gravity gear 3. The outer casing 1 is provided with a display area 113, which is transparent to facilitate observation of the indicator part 21 inside the receiving cavity 13. The indicator gear 2 reflects the direction of the front wheel by rotating its angle. The gravity gear 3 uses gravity to automatically calibrate the direction, ensuring that the indicator part 21 is always facing upward. The lower part of the gravity gear 3 is provided with a gravity part 31, so that the gravity part 31 is always in the vertical direction when there is no external force. Since the gravity gear 3 meshes with the indicator gear 2, the relative position of the indicator part 21 of the indicator gear 2 changes with the display area 113 according to the angle of the steering wheel rotation. The connecting component 4 is used to fix the entire wheel return indicator 100 on the steering wheel and can adjust the relative angle and relative position of the wheel return indicator 100 and the steering wheel to adapt to different vehicle models and driver driving habits.

[0047] Reference Figures 1-6 As shown, when the steering wheel is turned, the outer casing 1 rotates relative to the gravity gear 3 along with the steering wheel. The gravity part 31 of the gravity gear 3 is always in the vertical direction. The indicator gear 2 meshes with the gravity gear 3. At the same time as the gravity gear 3 rotates relative to the outer casing 1, the indicator gear 2 also rotates. Thus, the indicator part 21 indicates the rotation angle of the steering wheel (i.e., the rotation angle of the wheel) in the display area 113. By observing the position of the indicator part 21 in the display area 113, the driver can judge the rotation angle of the wheel and thus confirm whether the wheel has returned to center. The connecting component 4 is adjustable, which allows the driver to adjust the viewing angle and installation position of the wheel centering indicator 100 according to actual needs.

[0048] According to the embodiment of the present invention, the wheel centering indicator 100, through the cooperation of the indicator part 21 on the indicator gear 2 and the display area 113 on the housing 1, realizes the function of clearly displaying the direction of the front wheels. By setting a gravity part 31 on the gravity gear 3, the indicator part 21 is automatically kept pointing upward by gravity. By setting a connecting component 4, the relative position of the wheel centering indicator 100 and the steering wheel can be adjusted, and / or the angle between the wheel centering indicator 100 and the steering wheel can be adjusted. It is compatible with various steering wheels. The overall structure of the wheel centering indicator 100 is simple, stable and reliable.

[0049] Here, a gyroscope or angle sensor can be installed and connected to the vehicle's infotainment system. The system can then broadcast the rotation direction and angle information via voice, allowing the user to judge the wheel's rotation angle by hearing. This eliminates the need for the driver to look down at the wheel alignment indicator 100, thus improving driving safety.

[0050] In some embodiments of this utility model, the gear ratio between the indicator gear 2 and the gravity gear 3 is 10:1. It is understood that for every one rotation of the gravity gear 3, the indicator gear 2 rotates 36°; for every two rotations of the gravity gear 3, the indicator gear 2 rotates 72°. This visually reduces the steering wheel rotation angle, making it easier for the driver to observe and improving the sensitivity and practicality of the wheel alignment indicator 100, allowing the driver to quickly determine whether the front wheels are aligned or the angle of rotation.

[0051] like Figure 2 As shown, the indicator gear 2 has a half-circle of teeth, and the gravity gear 3 has a full-circle of teeth.

[0052] In some embodiments of this utility model, a first bearing seat 112 and a second bearing seat 122 are formed within the receiving cavity 13. An indicator bearing 6 is sleeved on the first bearing seat 112, and an indicator gear 2 is sleeved on the indicator bearing 6. A gravity bearing 7 is sleeved on the second bearing seat 122, and a gravity gear 3 is sleeved on the gravity bearing 7. Thus, by using the bearings and bearing seats in cooperation, the frictional resistance during the rotation of the gravity gear 3 and the indicator gear 2 is reduced, improving sensitivity. The bearing seats also serve as limiters, restricting the stability and reliability of the meshing of the gravity gear 3 and the indicator gear 2, preventing gear misalignment or jamming. The first bearing seat 112 and the second bearing seat 122 reduce wear and extend the service life of the wheel return indicator 100.

[0053] Reference Figure 2 and Figure 3As shown, the first bearing housing 112 and the second bearing housing 122 are both formed in the receiving cavity 13. The first bearing housing 112 and the second bearing housing 122 are both formed in a cylindrical shape. The first bearing housing 112 and the second bearing are both connected to the outer shell 1. The indicator bearing 6 is sleeved on the first bearing housing 112, the indicator gear 2 is sleeved on the indicator bearing 6, the gravity bearing 7 is sleeved on the second bearing housing 122, the gravity gear 3 is sleeved on the gravity bearing 7, the gravity gear 3 is rotatable relative to the outer shell 1, and the indicator gear 2 is rotatable relative to the outer shell 1.

[0054] In some embodiments of this utility model, the display area 113 is provided with five indicator points, and a limiting post 114 is provided on each side of the display area 113, with the limiting post 114 located within the receiving cavity 13. Thus, the five indicator points facilitate the driver's quick judgment of the front wheel's rotation direction and angle, thereby helping the driver quickly determine whether the steering wheel is straight. The limiting post 114 on each side of the display area 113 prevents the indicator gear 2 from over-rotating, avoids the indicator part 21 from exceeding the visible range, limits the indicator gear 2's rotation angle to an excessively large extent, and protects the indicator gear 2 and the gravity gear 3 from overload damage.

[0055] Reference Figure 1 As shown, the display area 113 is marked with "Left 2", "Left 1", "Center", "Right 1", and "Right 2". This allows the driver to intuitively judge the number of turns of the steering wheel and thus determine the rotation angle of the front wheels. Specifically, if the steering wheel is turned counterclockwise one full turn, the indicator gear 2 rotates 36° to the left, and the indicator part 21 of the indicator gear 2 points to "Left 1"; if the steering wheel is turned counterclockwise two full turns, the indicator gear 2 rotates 72° to the left, and the indicator part 21 of the indicator gear 2 points to "Left 2"; if the steering wheel is turned clockwise one full turn, the indicator gear 2 rotates 36° to the right, and the indicator part 21 of the indicator gear 2 points to "Right 1"; if the steering wheel is turned clockwise two full turns, the indicator gear 2 rotates 72° to the right, and the indicator part 21 of the indicator gear 2 points to "Right 2"; if the steering wheel is straightened, the indicator part 21 of the indicator gear 2 points to "Center".

[0056] Reference Figure 3 As shown, a limiting post 114 is provided at each end of the display area 113, and the limiting post 114 is connected to the side surface of the upper housing 11 facing the receiving cavity 13.

[0057] In some embodiments of this utility model, the outer casing 1 includes an upper casing 11 and a lower casing 12, which together define a receiving cavity 13. A first bearing seat 112 is formed on at least one of the upper casing 11 and the lower casing 12, and a second bearing seat 122 is formed on at least one of the upper casing 11 and the lower casing 12. Thus, the separate outer casing 1 facilitates the assembly of internal components; that is, the upper casing 11 and the lower casing 12 facilitate the assembly of gears and bearings into the receiving cavity 13, improving assembly efficiency and reducing production costs. Simultaneously, it facilitates maintenance; if components are damaged, separating the upper casing 11 and the lower casing 12 exposes the components within the receiving cavity 13, reducing the maintenance difficulty of the wheel alignment indicator 100.

[0058] Reference Figures 2-5 As shown, the outer shell 1 includes an upper shell 11 and a lower shell 12, with a receiving cavity 13 defined between the upper shell 11 and the lower shell 12. A first bearing seat 112 is formed in the upper shell 11, an indicator gear 2 is sleeved on an indicator bearing 6, a second bearing seat 122 is formed in the lower shell 12, and a gravity gear 3 is sleeved on a gravity bearing 7.

[0059] Optionally, the upper housing 11 is made of a transparent material, and an opaque pigment (such as paint) is coated on the upper housing 11, while the display area 113 remains transparent so that the indication position of the indicator section 21 can be observed.

[0060] In some embodiments of this utility model, the connecting component 4 includes: a mounting base 41, a telescopic rod 42, and a clamp 43. The mounting base 41 is connected to the lower housing 12, one end of the telescopic rod 42 is hinged to the mounting base 41, and the clamp 43 is hinged to the other end of the telescopic rod 42. It is understood that the telescopic rod 42 allows for adjustment of the relative position between the wheel alignment indicator 100 and the steering wheel. The height of the wheel alignment indicator 100 or its distance from the driver in the horizontal direction can be adjusted by adjusting the telescopic length of the telescopic rod 42. By setting multiple hinges, the angle between the wheel alignment indicator 100 and the steering wheel can be adjusted. The display area 113 of the wheel alignment indicator 100 can be adjusted to always face the driver's eyes by adjusting the relative rotation angle between the telescopic rod 42 and the mounting base 41 and / or the relative rotation angle between the telescopic rod 42 and the clamp 43, making it easier for the driver to observe and improving vehicle driving safety.

[0061] Reference Figures 2-5 As shown, the connecting assembly 4 includes a mounting base 41, a telescopic rod 42, and a gripper 43. The telescopic rod 42 has a first end 421 and a second end 422. The first end 421 is connected to the mounting base 41 and can rotate relative to the mounting base 41. The second end 422 can rotate relative to the gripper 43.

[0062] Here, an anti-slip pad can be installed on the gripper 43 to prevent the wheel alignment indicator 100 from sliding or falling off.

[0063] In some embodiments of this utility model, the upper housing 11 has a first connecting portion, and the lower housing 12 has a second connecting portion. The upper housing 11 and the lower housing 12 are connected by the first connecting portion and the second connecting portion. Thus, the connection stability between the upper housing 11 and the lower housing 12 is improved by the cooperation of the first connecting portion and the second connecting portion, preventing the connection between the upper housing 11 and the lower housing 12 from loosening or falling off, enhancing the overall rigidity of the outer shell 1, ensuring the structural strength of the outer shell 1 while preventing damage to the wheel alignment indicator 100, facilitating assembly and maintenance, and reducing the assembly and maintenance difficulty between the upper housing 11 and the lower housing 12.

[0064] Reference Figure 3 and Figure 6 As shown, it can be understood that the first connecting part is formed on the upper housing 11 and the second connecting part is formed on the lower housing 12. The first connecting part and the second connecting part cooperate to make the upper housing 11 and the lower housing 12 stably connected.

[0065] In some embodiments of this utility model, one of the first connecting portion and the second connecting portion is formed as a latching protrusion 111, and the other of the first connecting portion and the second connecting portion is formed as a groove 121, with the latching protrusion 111 extending into the groove 121. Thus, the cooperation between the latching protrusion 111 and the groove 121 reduces the difficulty of connecting the upper housing 11 and the lower housing 12, simplifies the connection steps between the upper housing 11 and the lower housing 12, improves the assembly efficiency and maintenance efficiency of the upper housing 11 and the lower housing 12, and reduces production and maintenance costs.

[0066] It is understandable that the first connecting part can be formed as a protrusion 111 and the second connecting part can be formed as a groove 121, or the first connecting part can be formed as a groove 121 and the second connecting part can be formed as a protrusion 111.

[0067] Reference Figure 6 As shown, the first connecting part is formed as a protrusion 111, and the second connecting part is formed as a groove 121. The protrusion 111 extends into and engages with the groove 121 so that the upper housing 11 and the lower housing 12 are stably connected.

[0068] In some embodiments of this utility model, the first connecting part includes multiple first connecting parts, which are arranged at intervals in the circumferential direction of the upper housing 11. The second connecting part includes multiple second connecting parts, which are arranged in a one-to-one correspondence with the multiple first connecting parts. Thus, by setting multiple first connecting parts and correspondingly arranged multiple second connecting parts, a multi-point connection between the upper housing 11 and the lower housing 12 is achieved, enhancing the overall rigidity of the outer shell 1, preventing the upper housing 11 and the lower housing 12 from falling off or moving, and the one-to-one correspondence arrangement facilitates the quick positioning and installation of the upper housing 11 and the lower housing 12, improving assembly convenience.

[0069] Reference Figure 2 and Figure 3 As shown, the first connecting part is formed as a latching protrusion 111, and the first connecting part includes 8 of them. The second connecting part is formed as a groove 121, and the second connecting part includes 8 of them. The 8 latching protrusions 111 and the 8 grooves 121 are arranged in a one-to-one correspondence, which ensures the stable connection between the upper housing 11 and the lower housing 12 and avoids the upper housing 11 from falling off during vehicle vibration or driving.

[0070] In some embodiments of this utility model, such as Figure 3 and Figure 6 As shown, the wheel alignment indicator 100 also includes a seal 5, which is disposed between the upper housing 11 and the lower housing 12. Therefore, the seal 5 prevents dust from entering the receiving cavity 13, avoiding affecting gear operation and preventing impurities from causing wear on the gears. The seal 5 also provides waterproofing, ensuring dryness within the receiving cavity 13, preventing moisture from corroding the gears, and extending the service life of the wheel alignment indicator 100.

[0071] The following reference Figures 1-6 A wheel alignment indicator 100 according to a specific embodiment of the present invention will be described.

[0072] Reference Figures 1-6 As shown, the wheel return indicator 100 includes: a housing 1, an indicator gear 2, a gravity gear 3, a connecting assembly 4, and a seal 5.

[0073] When the steering wheel is turned, the outer casing 1 rotates relative to the gravity gear 3 along with the steering wheel. The gravity part 31 of the gravity gear 3 is always in the vertical direction. The indicator gear 2 meshes with the gravity gear 3. While the gravity gear 3 rotates relative to the outer casing 1, the indicator gear 2 also rotates. Thus, the indicator part 21 indicates the rotation angle of the steering wheel (i.e., the rotation angle of the wheel) in the display area 113. By observing the position of the indicator part 21 in the display area 113, the driver can determine the rotation angle of the wheel and thus confirm whether the wheel has returned to center. The connecting component 4 is adjustable, allowing the driver to adjust the viewing angle and installation position of the wheel centering indicator 100 according to actual needs.
