[0031] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0032] Example 1: Reference Figure 1-4 An embodiment of the utility model discloses a device for displaying the wheel alignment of a car when it is parked. The device is installed on a steering wheel and specifically comprises an upper cover 1 and a lower cover 2 connected to each other. In the embodiment of the utility model, the upper cover 1 and the lower cover 2 are detachably connected to facilitate assembly and maintenance operations.

[0033] The lower cover 2 has a guide groove 21 inside, and an indicator 22 slides in the guide groove 21. The indicator 22 can be a fluorescent ball, a magnetic ball, a metal ball or other gravity materials. A positioning portion 23 is also provided inside the guide groove 21. When the steering wheel is returned to the center, the indicator 22 slides into the positioning portion 23 under gravity, so that the correct position of the vehicle can be accurately displayed, which is convenient for the driver to return to the center, saving effort and worry, especially for those who are just learning to drive.

[0034] In some embodiments, the guide groove 21 in the utility model is a spiral groove opened on the end face of the lower cover 2, and the positioning portion 23 is a positioning groove opened at the bottom of the guide groove 21. Of course, in other embodiments, the guide groove 21 can also be set as a through hole, wherein the indicator 22 is a spherical member. In some embodiments, the spherical member is a fluorescent ball made of fluorescent material, which is convenient for the vehicle to park and straighten at night or in dim light. The light emitted by the fluorescent ball makes it easier to observe the position of the fluorescent ball in the spiral groove.

[0035] The spherical member rotates along the spiral groove under the influence of gravity, so that when the indicator 22 enters the positioning groove, it indicates that the current wheel is in the return position.

[0036] When installing the device, first align the wheel to be installed with the device, and at the same time, make the positioning portion 23 face downward along the front of the steering wheel during installation;

[0037] When the steering wheel is turned right, the device rotates synchronously therewith, and the indicator 22 in the spiral groove rolls to the inner circle of the spiral groove due to gravity. When the steering wheel is rotated to the right to the end, that is, the dead position, the indicator 22 in the spiral groove rolls to the top of the innermost circle of the spiral groove.

[0038] When the steering wheel is turned to the left, the indicator 22 in the spiral groove rolls to the bottom of the outermost circle of the spiral groove. When the steering wheel is turned to the left or right for a certain number of times when parking, the indicator 22 rolls to the position of the positioning part 23 to accurately display the correct position of the wheel.

[0039] It should be noted that the spiral groove described in the embodiment of the present invention adopts a right-hand spiral direction. Of course, those skilled in the art know that a left-hand spiral direction can also be adopted in other embodiments, and the effect is the same.

[0040] It should be noted that in the embodiment of the utility model, the number of turns of the spiral groove is the same as the sum of the number of right-hand turns and the number of left-hand turns of the steering wheel. The positioning groove is arranged at half of the total number of turns of the spiral groove. Through this structural design, it is ensured that when the wheel is in the return position, the indicator 22 can be exactly in the middle of the spiral groove. Therefore, during the return process, by observing the maximum displacement of the indicator 22 at both ends of the spiral groove, the maximum right-hand and maximum left-hand positions of the steering wheel can be synchronously indicated.

[0041] On the basis of the above-mentioned embodiment, the upper cover 1 and the lower cover 2 in the utility model are connected by a connecting component 3, wherein the upper cover 1 is a transparent component. Furthermore, in the present embodiment, the upper cover 1 is preferably configured as a transparent organic glass cover, so as to facilitate observation of the sliding position of the internal indicator 22.

[0042] In some embodiments, the connecting component 3 in the utility model includes a connecting hole 31 arranged on the tail end of the guide groove 21, and a through hole 32 is provided on the end surface of the upper cover 1. The through hole 32 and the connecting hole 31 are connected by a fastener. The fastener is preferably configured as a bolt. In order to ensure the consistency of the appearance of the entire device, the through hole 32 can also be configured as a countersunk hole. When fixing, the end of the bolt is buried in the countersunk hole to improve the surface flatness of the upper cover 1.

[0043] Furthermore, in this embodiment, the device is connected to the outer ring of the steering wheel through an external component 5. Specifically, in this embodiment, the external component 5 is a mounting bracket. The device and the mounting bracket can be fastened by fasteners. The mounting bracket can be configured as an elastic clip, which is clamped and fixed on the steering wheel by elastic force to achieve fixation of the device without affecting driving operations.

[0044] In addition, the present invention also proposes a method for displaying the alignment of the wheels of a parked vehicle, which uses the above-mentioned device and includes the following steps:

[0045] Step 1: When the wheel is in the straightened state, fix the device on the middle or outer ring of the steering wheel, and make the positioning part 23 face directly below the steering wheel;

[0046] Step 2: During the process of returning the parking wheel to the center position, turn the steering wheel to adjust the wheel position and observe the sliding of the indicator 22;

[0047] Step 3: When the indicator 22 slides into the positioning portion 23, the wheel return position is found.

[0048] Example 2: Reference Figure 5 In this embodiment, the same points as those in the first embodiment are not described in detail, and the difference lies in that:

[0049] This embodiment also includes a display component 4, and the display component 4 is used to display the current position of the indicator 22.

[0050] In some embodiments, the display component 4 includes a central shaft 41 fixed on the upper cover 1, and a pointer 42 is rotatably connected to the outer side of the central shaft 41;

[0051] Among them, the indicator 22 is a magnetic ball, and the pointer 42 is a magnetically attractive part. Specifically, in this embodiment, the pointer 42 can be set to an iron needle, so that the position can be changed by the attraction of the magnetic ball to improve the intuitiveness of user observation. It should be noted that in this embodiment, the pointer 42 is set on the inner side of the upper cover 1, so as to avoid problems such as inaccurate indication caused by user accidental touch.

[0052] That is to say, in this embodiment, by providing the pointer 42, when the wheel is in the process of returning to the center, the current position of the indicator 22 can be determined by observing the position change of the pointer 42, thereby improving the convenience of observation.

[0053] Example 3: Reference Figure 6 In this embodiment, the same points as those in Embodiment 1 and Embodiment 2 are not described in detail, and the difference lies in that:

[0054] The device described in this embodiment is connected to the middle part of the steering wheel through an external component 5. In this embodiment, the external component 5 can be set to double-sided tape, and the device can be bonded to the middle panel of the steering wheel through the double-sided tape. Of course, technical personnel in the relevant field know that the device can also be bonded to the outer ring of the steering wheel by double-sided tape to improve the convenience of connection.

[0055] In addition, the above-mentioned embodiment takes the wheel return of a car as an example. Those skilled in the art know that the device and method for displaying the wheel return of a car when it is parked described in the utility model are also suitable for various types of special vehicles and military vehicles, etc., and can also be used for fishing boats, yachts and ship rudders, etc.

[0056] In summary, the utility model adopts the design of the indicator 22, which is moved inside the guide groove 21 under the action of gravity. When the wheel is aligned, the indicator 22 can fall into the positioning part 23, so that the current wheel alignment status can be indicated, and the vehicle's alignment position can be accurately displayed, which is convenient for the driver's alignment operation, saving effort and worry, especially for those who are just learning to drive. The whole device does not require power supply, and the structural design is simple and the manufacturing cost is low. At the same time, the installation method is simple, no maintenance is required, and the wheel alignment is accurately positioned to protect the vehicle from loss. At the same time, it is also convenient for the driver to operate the wheel alignment when parking.

[0057] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
