Description

Technical Field

[0001] The present invention relates to the field of watches, in particular to a time indicating mechanism and a watch comprising the time indicating mechanism. Background Art

[0002] Nowadays, watches are no longer simply a tool for telling time, but rather a form of accessory for consumers. Ordinary watches use traditional pointer displays: the hour hand indicates the hour, the minute hand indicates the minute, and the second hand indicates the second. Time is read by following the scale on the dial below the pointer. As people's pursuit of novelty and novelty continues to develop, they are no longer satisfied with the conventional indications of watches. While watches can still tell time, they should also offer a wider range of functions to meet the needs of different users. There are two types of watch indication structures: one in which the dial remains stationary while the pointer moves, and the other in which the pointer remains stationary while the dial moves. The pointer's movement path generally matches the shape of the dial, and most pointers follow a circular path. Summary of the Invention

[0003] The technical problem to be solved by this invention is that existing watches only serve the purpose of reading the time, which is a single function. Based on this technical problem, the purpose of this invention is to design a time indicating mechanism with a novel motion trajectory curve of the pointer and a more interesting indicating structure. To achieve this goal, the technical solution adopted by this invention is as follows:

[0004] A time indicating mechanism comprises a face, a pointer, a time indicating disc, a guide post, and a seconds tube, wherein the pointer, the time indicating disc, and the guide post are all connected to the face; the pointer is provided with a through slot, and the through slot and the guide post cooperate to define the motion trajectory of the pointer; the pointer moves about the seconds tube as an axis; and the seconds tube is connected to a movement.

[0005] Furthermore, the time indicating mechanism further comprises a splint assembly, and the splint assembly is connected to the literal.

[0006] Furthermore, the splint assembly includes an upper splint and a lower splint; the upper splint is fixedly connected to the lower splint, an axial hole is provided on the upper splint, the guide column passes through the axial hole and is connected to the upper splint, and a bearing is provided between the guide column and the axial hole; the lower splint is provided through the second support column, the second support column is connected to the literal, and a screw passes through the upper splint and is connected to the second support column.

[0007] Furthermore, the upper splint is composed of two fan-shaped structures with smooth transitions towards each other, both sides of the fan-shaped structure are concave arc structures, and the upper splint is also provided with a through hole.

[0008] Furthermore, the shape of the time indicating disc matches the movement trajectory of the pointer.

[0009] Furthermore, the motion trajectory of the pointer is crescent-shaped.

[0010] Furthermore, the time indicating plate includes an upper cover and a lower cover, the pointer is located between the upper cover and the lower cover, and the upper cover and the lower cover are connected by a first support column; the upper cover is made of transparent material and is provided with a time scale.

[0011] Furthermore, the second tube includes a bearing portion, a connecting portion, a counterweight portion and a movement connecting hole; the bearing portion is connected to the pointer, and the bearing portion is arranged at an end of the connecting portion close to the guide column; the counterweight portion is arranged at an end away from the bearing portion, the mass of the counterweight portion is greater than the mass of the connecting portion, and the movement connecting hole is arranged at the intersection between the connecting portion and the counterweight portion.

[0012] Furthermore, the time indicating mechanism further comprises a fixed movement ring, and the movement and the dial are both connected to the fixed movement ring.

[0013] Another object of the present invention is to provide a watch comprising the above-mentioned time indicating mechanism.

[0014] The beneficial effects of the present invention are as follows: (1) The movement trajectory of the pointer is achieved through the cooperation of the guide column and the second hand, which determines the movement trajectory of the pointer and breaks through the conventional circular motion; (2) To ensure the stability of the pointer movement, a second tube is provided to achieve a counterweight effect; (3) The shapes of the time indicator and the splint echo each other, which improves the aesthetics.

DETAILED DESCRIPTION

[0020] The present invention will be further described below with reference to the embodiments and accompanying drawings.

[0021] Example 1

[0022] like Figures 1 to 3 As shown, a time indicating mechanism comprises a dial face 1, a pointer 2, a time indicator disc 3, a guide post 4, and a seconds hand 5. The pointer 2, time indicator disc 3, and guide post 4 are all connected to the dial face 1. The pointer 2 is provided with a through slot 21, which cooperates with the guide post 4 to define the motion trajectory of the pointer 2. The pointer 2 moves about the seconds hand 5. The seconds hand 5 is connected to a movement 10. The dial face 1 serves as the main assembly component. The movement 10 outputs power to the seconds hand, which rotates and drives the pointer 2 in a circular motion. The through slot 21 in the pointer 2 and the cooperating guide post 4 change the motion trajectory of the seconds hand, thus freeing it from a circular trajectory.

[0023] Specifically, the time indicating mechanism further includes a plate assembly 6, which is connected to the dial face 1 and is used to secure the pointer 2. The plate assembly 6 includes an upper plate 61 and a lower plate 62. The upper plate 61 is fixedly connected to the lower plate 62, and the upper plate 61 is provided with an axial hole 611. The lower end of the guide post 4 is connected to the dial face 1 via a bearing. The guide post 4 passes through the axial hole 611 and is connected to the upper plate 61. A bearing 612 is provided between the guide post 4 and the axial hole 611. The lower plate 62 is disposed through a second support post 621, which is connected to the dial face 1. A screw 63 passes through the upper plate 61 and is connected to the second support post 621, thereby locking the upper plate 61 to the lower plate 62.

[0024] Specifically, the upper plate 61 is composed of two opposing, smoothly transitioning fan-shaped structures, each with its sides formed into an inwardly concave arc. A through-hole 622 is also provided on the upper plate 1. The shape of the upper plate 61 echoes that of the indicator dial 3, and the paths of its two sides also resemble a crescent. As the seconds tube 4 rotates, the trajectory of the seconds tube 4 is displayed through the through-hole 622.

[0025] Specifically, the shape of the time indicating disc 3 matches the motion trajectory of the pointer 2 .

[0026] Specifically, the motion trajectory of the pointer 2 is as follows: Figure 4 It is crescent-shaped. Figure 4 As shown, the needle trajectory calculation formula is as follows: X (t) =-X*sin(B)-Y2*sin(A); Y (t) =-X*cos(B)+Y2*COS(A); where sin(A)=X / Y1*sin(B); where X (t) , Y (t)They represent the X and Y coordinates of a point on the needle's trajectory, respectively. X represents the distance from the seconds tube axis to the pointer axis, Y1 represents the distance from the pointer axis to the guide post, and Y2 represents the distance from the pointer axis to the pointer tip. Figure 4 O1 represents the seconds tube axis, which is the dot; O2 represents the pointer axis, and O3 represents the pointer tip.

[0027] Specifically, the time indicator disk 3 includes an upper cover 31 and a lower cover 32, and the pointer 3 is located between the upper cover 31 and the lower cover 32. The upper cover 31 and the lower cover 32 are connected by a first support column 33, so that an accommodating space is formed between the upper cover 31 and the lower cover 32 to prevent the pointer from interfering with the upper cover 31 or the lower cover 32 when rotating; the upper cover 31 is made of transparent material to facilitate observation of the indicated position of the pointer, and a time scale is provided on the upper cover 31.

[0028] Specifically, the seconds tube includes a bearing 51, a connecting portion 52, a counterweight 53, and a movement connection hole 54. The bearing 51 is connected to the pointer 2 and is located at the end of the connecting portion 52 closest to the guide post 4. The counterweight 53 is located at the end farther from the bearing 51, with a mass greater than that of the connecting portion 52. The movement connection hole 54 is located at the junction of the connecting portion 52 and the counterweight 53. When the seconds tube rotates, one end of the second tube is connected to the pointer, causing it to tilt. Therefore, the end opposite the pointer requires a configuration.

[0029] Specifically, the time indicating mechanism further comprises a fixed movement ring, and the movement and the dial are both connected to the fixed movement ring.
