[0001] The present invention relates to the technical field of instrument panels, and in particular, to an automotive instrument panel. Background Art

[0002] With the progress of technology, automobiles have been widely used in our country. An automotive instrument panel is a common automotive accessory. Currently, most automobiles use pointer-type instrument panels. By observing the indication position of the pointer on the circular scale, the current operating conditions of the automobile can be known, such as the driving speed and engine speed of the automobile. When using the existing automotive instrument panel, due to the influence of the in-vehicle sanitary conditions, dirt will appear on the instrument glass, blocking the driver from reading the instrument. Cleaning the instrument glass during driving is very dangerous and likely to cause traffic accidents. To solve the above problems, the present invention is designed. Summary of the Invention

[0030] It is worth mentioning that, as Figure 6 and Figure 7As shown, the tooth directions of the first ratchet tooth 411 and the second ratchet tooth 441 are the same, that is, when the first ratchet tooth 411 and the second ratchet tooth 441 rotate clockwise, they can both rotate normally along the inner ring of the inner ratchet wheel 46, and when the first ratchet tooth 411 and the second ratchet tooth 441 rotate counterclockwise, they will drive the inner ratchet wheel 46 to rotate counterclockwise synchronously.

[0031] Preferably, as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 8 As shown, the transmission mechanism includes: a fourth bevel gear 45, fixedly connected to the outside of the inner ratchet wheel 46; a fixed shaft 32, rotatably connected to the inside of the housing 1 and fixedly connected to the instrument glass 31, and a fifth bevel gear 55 is fixedly connected to one end of the fixed shaft 32 away from the instrument glass 31; a sixth bevel gear 51, rotatably connected to the inside of the housing 1 and meshing with the fifth bevel gear 55, and a ratchet tooth ring 511 is provided on the end face of the sixth bevel gear 51; a transmission shaft 56, rotatably connected to the inside of the housing 1, a seventh bevel gear 47 meshing with the fourth bevel gear 45 is fixedly connected to one end of the transmission shaft 56, the other end of the transmission shaft 56 penetrates into the inside of the ratchet tooth ring 511 and is fixedly connected to a turntable 52, a third chute 521 is provided on the turntable 52, a third ratchet tooth 54 is slidably connected in the third chute 521, and a third elastic member 53 for pushing the third ratchet tooth 54 to mesh with the ratchet tooth ring 511 is provided between the third ratchet tooth 54 and the third chute 521.

[0032] It is worth mentioning that, as Figure 6 , Figure 7 and Figure 8 As shown, the first elastic member 412, the second elastic member 442 and the third elastic member 53 are all elastic sheets, and the elastic sheets are V-shaped.

[0033] Preferably, as Figure 2 As shown, an upper cover 11 is covered above the cleaning cotton 13 on the upper watch case 12.

[0034] Preferably, as Figure 1 and Figure 3 As shown, three transmission mechanisms are provided, and the three transmission mechanisms are distributed in a circumferential array.

[0035] Preferably, as Figure 2 As shown, a through hole 121 for observing the pointer 21 is provided on the upper watch case 12.

[0036] It can be understood that, as Figure 1 and Figure 2As shown, there are three through holes 121, which are arranged in a circumferential array, and the through holes 121 correspond to the pointer 21.

[0037] Working principle:

[0038] When the pointer shaft 22 drives the pointer 21 to swing clockwise during the driving of the vehicle, the first bevel gear 41 will be driven to rotate clockwise synchronously. At this time, the first ratchet tooth 411 rotates clockwise with the first bevel gear 41, that is, rotates along its inclined plane direction, and the first ratchet tooth 411 will slide along the direction of the first chute 414 and squeeze the first elastic member 412, so that the first ratchet tooth 411 and the internal ratchet 46 rotate relatively, so the internal ratchet 46 will not be driven to rotate. Moreover, the clockwise rotation of the first bevel gear 41 will drive the third bevel gear 43 to rotate counterclockwise through the second bevel gear 42, so that the swing plate 44 rotates counterclockwise together with the third bevel gear 43, and then drives the second ratchet tooth 441 to rotate counterclockwise. At this time, the second ratchet tooth 441 and the internal ratchet 46 are in planar contact, so as to drive the internal ratchet 46 to rotate counterclockwise;

[0039] When the pointer shaft 22 drives the pointer 21 to swing counterclockwise, the first bevel gear 41 will be driven to rotate counterclockwise synchronously. At this time, the first ratchet tooth 411 rotates counterclockwise with the first bevel gear 41, and drives the internal ratchet 46 to rotate counterclockwise in the case of planar contact. Moreover, the counterclockwise rotation of the first bevel gear 41 will drive the third bevel gear 43 to rotate clockwise through the second bevel gear 42, and then drive the second ratchet tooth 441 to rotate clockwise accordingly, that is, the second ratchet tooth 441 rotates along its inclined plane direction. At this time, the second ratchet tooth 441 slides along the direction of the second chute 444 and squeezes the second elastic member 442, so that the second ratchet tooth 441 and the internal ratchet 46 rotate relatively, so the internal ratchet 46 will not be driven to rotate; that is, when the pointer 21 swings back and forth, the internal ratchet 46 is always driven to rotate counterclockwise;

[0040] When the internal ratchet 46 rotates counterclockwise, it drives the fourth bevel gear 45 to rotate counterclockwise synchronously, and then drives the seventh bevel gear 47 to rotate clockwise. Through the transmission shaft 56, it drives the turntable 52 to rotate clockwise, and then drives the sixth bevel gear 51 to rotate under the mutual cooperation of the third ratchet tooth 54 and the ratchet tooth ring 511. The rotation of the sixth bevel gear 51 drives the fifth bevel gear 55 to rotate, and then drives the instrument glass 31 to rotate through the fixed shaft 32. During the rotation of the instrument glass 31, the cleaning cotton 13 in the upper case 12 will clean the instrument glass 31, so that the instrument glass 31 is always kept clean; and after the cleaning cotton 13 is used for a long time, the upper cover 11 above the cleaning cotton 13 can be opened to replace the cleaning cotton 13 to maintain the cleaning effect of the cleaning cotton 13;

[0041] Since each table drives the respective turntable 52 to rotate, although the rotation speeds of the turntables 52 are different due to the different swinging speeds of the pointers 21, due to the cooperation relationship between the third ratchet 54 and the ratchet tooth ring 511, only the turntable 52 with the fastest rotation speed will affect the sixth bevel gear 51. Therefore, each table does not affect each other and can control the instrument glass 31.

[0042] The technical features of the above-described embodiments can be combined arbitrarily. For the sake of concise description, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope described in this specification.

[0043] The above-described embodiments only represent several implementation manners of the present invention. The description is relatively specific and detailed, but it should not be construed as a limitation on the scope of the invention patent. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several modifications and improvements can be made, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the present invention patent shall be subject to the appended claims.
