Description

Technical Field

[0001] The present invention relates to the technical field of watches, and specifically to a watch component with a multi-dial interface display. Background Art

[0002] A mechanical watch stores energy after the mainspring is wound up. As the mainspring slowly unwinds, the energy is released to drive the barrel wheel to rotate. The barrel wheel transmits power to each gear in turn through a gear transmission system, enabling the gears to rotate at a specific speed and law for time display. Its interior includes a large number of precision gears, escapement mechanisms and other transmission structures. In actual use, the working environment of the watch is complex, especially in high-temperature and vibration environments. For example, when playing ball in summer, it is exposed to direct sunlight and vibration, and the temperature of the in-vehicle movement can reach as high as sixty or seventy degrees Celsius under direct sunlight in summer and resonate during vehicle driving. High temperature will cause the gear clearance of the watch to increase. The reason is that gears are usually fixed on structures such as bridge plates, shafts, and bearings, and the thermal expansion coefficients of these components may be different from those of the gears. For example, the thermal expansion coefficient of a brass bridge plate is larger, and it will expand outwards at high temperature, driving the gear shaft away from the mating gear, resulting in an increase in the center distance between the two gears. Although the gears will also expand and the tooth thickness will increase, the increase in the center distance is much greater than the increase in the tooth thickness. When the gear clearance increases, the gears will shake and impact each other, and the pointer will also generate large shaking impacts in a vibration environment, greatly intensifying the wear of the movement module, resulting in the movement module being extremely easy to damage and the timekeeping being inaccurate under such extreme working conditions. Summary of the Invention

[0003] The purpose of the present invention is to provide a watch component with a multi-dial interface display to solve the problems raised in the above background art.

[0004] To achieve the above purpose, the present invention provides the following technical solution: A watch component with a multi-dial interface display includes a movement module, as well as an hour hand driving ring and a minute hand driving ring arranged on the movement module. The movement module drives the hour hand driving ring and the minute hand driving ring to rotate according to the hour hand period and the minute hand period respectively. Both the hour hand driving ring and the minute hand driving ring are annular, and a disc pointer is fixedly arranged in each of the hour hand driving ring and the minute hand driving ring. An annular groove is formed on the outer surface of the hour hand driving ring, and the hour hand driving ring and the annular groove are coaxially arranged. A damping contact block and a temperature-sensitive damping pressing member are arranged outside the annular groove; when the temperature of the watch rises, the temperature-sensitive damping pressing member drives the damping contact block to squeeze the annular groove, so that the rotational damping of the hour hand driving ring is increased.

[0005] The temperature-sensitive damping pressing member includes a right-angle support member and a metal cavity cylinder. The right-angle support member is fixedly installed on the movement module, and the end of the metal cavity cylinder is integrally fixed with the right-angle support member. Fins are arranged on the surface of the metal cavity cylinder.

[0006] Inside the metal cylinder, there is a piston part which is in sealed contact with the inner wall surface of the metal cylinder. On one side of the piston part, a sealed coupling shaft is fixedly arranged. On the right-angle support member, a sealing sleeve is fixedly arranged, and the sealed coupling shaft is sealed and inserted through the sealing sleeve and extends to the outside of the metal cylinder.

[0007] At one end of the sealed coupling shaft away from the piston part, a split pressing plate is fixedly arranged. On the right-angle support member, a limit pin is fixedly arranged, and the limit pin is inserted through the split pressing plate to limit the split pressing plate, so that the split pressing plate can only move along the axis direction of the sealed coupling shaft.

[0008] On the surface of the right-angle support member, a positioning hole is provided, and a positioning end shaft is arranged in the positioning hole. One end of the positioning end shaft is fixedly installed with a damping contact block; When the temperature of the watch rises and reaches the preset range, the temperature is conducted to the inside of the metal cylinder, causing the gas inside the metal cylinder to expand, driving the piston part to move axially, driving the split pressing plate to be in pressing contact with the positioning end shaft, applying pressure to the damping contact block through the positioning end shaft, so that the damping contact block is in pressing contact with the annular groove, and at this time, the rotation damping of the hour hand driving ring is increased.

[0009] On the watch core module, a support side shaft is fixedly arranged, and a support wheel is rotatably sleeved outside the support side shaft, and the hour hand driving ring and the minute hand driving ring are respectively limited by the support wheel.

[0010] An hour hand indicator disk is arranged around the outside of the hour hand driving ring, and a minute hand indicator disk is arranged around the outside of the minute hand driving ring. An aiming pupil is eccentrically arranged on the disk pointer, and the aiming pupil on the disk pointer cooperates with the hour hand indicator disk and the minute hand indicator disk respectively to display the hour and minute time.

[0011] An energy pointer is arranged on the watch core module to display the remaining energy of the mainspring in the watch core module.

[0012] Compared with the prior art, the beneficial effects of the present invention are: The watch component with multi-disk interface display of the present invention drives the disk pointer to display time through the hour hand driving ring and the minute hand driving ring, realizes the multi-disk display of hours and minutes, and can form a binocular effect of a human face in cooperation with the watch core module, which is more beautiful.

[0013] The present invention is cooperated with the damping contact block and the temperature-sensitive damping pressing member set, etc., and can automatically increase the rotation damping of the hour hand when the temperature of the watch rises and causes the gap of the metal expansion gear to increase. By increasing the damping, the shaking between the pointer and the gear is suppressed. Under the additional conditions of movement or vibration, the impact wear of the components can be effectively reduced, and the service life of the watch core module under extreme working conditions of high temperature and vibration can be prolonged.

Detailed implementation manners

[0022] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0023] Please refer to Figures 1 to 7 , the present invention provides a technical solution: a watch component with a multi-disc interface display, as Figure 3As shown in the figure, it includes a movement module 1, an hour - hand driving ring 2 and a minute - hand driving ring 3 arranged on the movement module 1. The movement module 1 is composed of a barrel, a winding mechanism, a gear system, an escapement mechanism and a balance wheel and hairspring system, etc. The movement module 1 drives the hour - hand driving ring 2 and the minute - hand driving ring 3 to rotate according to the hour - hand period and the minute - hand period respectively. The movement module 1 is the movement principle of a mechanical watch under the existing technology, which will not be elaborated here.

[0024] Both the hour - hand driving ring 2 and the minute - hand driving ring 3 are in a circular - ring shape, and a disc - shaped pointer 4 is fixedly arranged in each of the hour - hand driving ring 2 and the minute - hand driving ring 3; as Figure 3 shown in the figure, the disc - shaped pointer 4 is in a disc shape, the movement module 1 presents a human - face shape, and the disc - shaped pointers 4 are arranged at the binocular positions to simulate binoculars.

[0025] As Figure 4 shown in the figure, an annular groove 5 is formed on the outer surface of the hour - hand driving ring 2. The hour - hand driving ring 2 and the annular groove 5 are coaxially arranged. A damping contact block 6 and a temperature - sensitive damping pressing part are arranged outside the annular groove 5; when the temperature of the watch rises, the temperature - sensitive damping pressing part drives the damping contact block 6 to squeeze the annular groove 5, so that the rotational damping of the hour - hand driving ring 2 is increased. The temperature - sensitive damping pressing part includes a right - angled support 7 and a metal cylinder 701. The right - angled support 7 is fixedly installed on the movement module 1, and the end of the metal cylinder 701 is integrally fixed with the right - angled support 7. Fins 702 are arranged on the surface of the metal cylinder 701.

[0026] A piston part 703 is arranged inside the metal cylinder 701. The piston part 703 is in sealing contact with the inner wall surface of the metal cylinder 701. A sealing connecting shaft 704 is fixedly arranged on one side of the piston part 703. A sealing sleeve 705 is fixedly arranged on the right - angled support 7. The sealing connecting shaft 704 is hermetically inserted through the sealing sleeve 705 and extends outside the metal cylinder 701.

[0027] A split pressing plate 706 is fixedly arranged at the end of the sealing connecting shaft 704 away from the piston part 703. A limit pin 707 is fixedly arranged on the right - angled support 7. The limit pin 707 passes through the split pressing plate 706 to limit the split pressing plate 706, so that the split pressing plate 706 can only move along the axial direction of the sealing connecting shaft 704.

[0028] The surface of the right-angle support member 7 is provided with a positioning hole 708, and a positioning end shaft 709 is arranged in the positioning hole 708. One end of the positioning end shaft 709 is fixedly installed with the damping contact block 6. When the temperature of the watch rises and reaches the preset range, the temperature is conducted to the inside of the metal cavity 701, causing the gas inside the metal cavity 701 to expand, driving the piston portion 703 to move axially, driving the split pressure plate 706 to be in pressing contact with the positioning end shaft 709, applying pressure to the damping contact block 6 through the positioning end shaft 709, so that the damping contact block 6 is in pressing contact with the annular groove 5, and at this time, the rotational damping of the hour hand driving ring 2 is increased.

[0029] A support side shaft 101 is fixedly arranged on the watch core module 1, and a support wheel 102 is rotatably sleeved outside the support side shaft 101, and the hour hand driving ring 2 and the minute hand driving ring 3 are respectively limited by the support wheel 102.

[0030] An hour hand indicating disk 103 is arranged around the outside of the hour hand driving ring 2, and a minute hand indicating disk 104 is arranged around the outside of the minute hand driving ring 3. An aiming pupil 401 is eccentrically arranged on the disk pointer 4, and the hour and minute time is displayed by the cooperation of the aiming pupil 401 on the disk pointer 4 with the hour hand indicating disk 103 and the minute hand indicating disk 104 respectively.

[0031] An energy pointer 105 is arranged on the watch core module 1, and the remaining energy of the mainspring in the watch core module 1 is displayed by the energy pointer 105.

[0032] As Figure 4 and Figure 6 As shown in

[0033] A stepped groove 603 is provided on the contact convex portion 602, a buffer cavity 604 is provided inside the contact convex portion 602, a sludge storage cavity 605 and a hydraulic fluid storage cavity 606 are provided inside the damping contact block 6, and a viscous hydraulic fluid is filled in the hydraulic fluid storage cavity 606; the stepped groove 603 is communicated with the sludge storage cavity 605 through the buffer cavity 604, a one-way sheet 607 is arranged between the buffer cavity 604 and the sludge storage cavity 605, a support elastic member 608 is arranged on one side of the one-way sheet 607, and the one-way blocking function is realized through the one-way sheet 607, so that the sludge in the buffer cavity 604 will not flow out after being sucked into the sludge storage cavity 605; a wetting brush 609 is embedded and installed in the contact convex portion 602, one end of the wetting brush 609 is inserted into the hydraulic fluid storage cavity 606 to wet the wetting brush 609 with the viscous hydraulic fluid, and the other end of the wetting brush 609 contacts the annular groove 5. During the rotation of the hour hand driving ring 2, first, the sludge adhering to the surface of the annular groove 5 and containing metal powder chips is scraped by the contact convex portion 602 and buffered in the buffer cavity 604, and then the viscous hydraulic fluid is replenished and brushed again through the wetting brush 609.

[0034] As Figure 7 shown, an oil-proof breathable filter membrane 610 is arranged in the sludge storage cavity 605, a tail end cavity 611 is provided in the damping contact block 6, the tail end cavity 611 is communicated with the sludge storage cavity 605, and oil-proof and breathable functions are realized through the oil-proof breathable filter membrane 610, so as to prevent the sludge in the sludge storage cavity 605 from being sucked into the tail end cavity 611 when the tail end cavity 611 sucks air under negative pressure; a first one-way valve 612 is arranged in the tail end cavity 611, and the gas in the sludge storage cavity 605 flows unidirectionally towards the tail end cavity 611 through the first one-way valve 612. A negative suction hole 613 is communicatedly arranged in the tail end cavity 611. As Figure 4 shown, a connecting air nozzle 614 is communicatedly arranged outside the metal cavity cylinder 701, and the negative suction hole 613 and the connecting air nozzle 614 are communicated through a pipeline.

[0035] A second one-way valve 615 is embedded and installed on the metal cavity cylinder 701, and the second one-way valve 615 enables the gas in the metal cavity cylinder 701 to flow unidirectionally towards the outside. Both the second one-way valve 615 and the connecting air nozzle 614 are located on the side of the piston portion 703 away from the sealing coupling shaft 704.

[0036] As shown in Figure 1 and Figure 2 the present invention, the overall shape of the watch core module 1 is close to the shape of a human face. By using the disc pointer 4 as the eyeball and the pointing pupil 401 as the pupil, the effect of being close to the human face is realized, and by using the rotational position difference between the hour hand and the minute hand, a relatively funny dial effect is realized, thereby improving the aesthetics.

[0037] When the watch is heated, as Figure 4 and Figure 5As shown in , the temperature is conducted through the fins 702, causing the gas in the metal cavity 701 to heat up and expand, driving the piston part 703 to move to the left. During the process of the piston part 703 moving to the left, the split pressure plate 706 is driven to move to the left through the sealing shaft 704. At the beginning, the split pressure plate 706 and the positioning end shaft 709 are not in contact with each other. As the split pressure plate 706 moves to the left, the split pressure plate 706 applies axial pressure to the positioning end shaft 709, and the positioning end shaft 709 pushes the damping contact block 6 to squeeze and contact the annular ring groove 5, thereby increasing the rotation damping of the hour hand driving circle 2. Similarly, it automatically resets when the temperature recovers.

[0038] Since the hour hand drive ring 2 is the hour hand end, the rotation speed is the slowest and the torque is the largest, increasing the damping of the hour hand drive ring 2 within a reasonable range will not have a significant impact on the energy consumption of the barrel. Only by sacrificing a small amount of the barrel's energy, the internal gear shaking of the watch movement module 1 is reduced under extreme working conditions, thereby extending the life of the watch movement module 1. The principle that the increase in the damping of the hour hand drive ring 2 can suppress the shaking of gears and pointers is that when the driving wheel (such as the minute hand gear) changes the direction of rotation or transmits power, due to the existence of a gap, the driving wheel will first "idle" for a distance until it hits the tooth surface of the driven wheel (such as the hour hand gear), generating an instantaneous impact force, causing the gear to shake; and by setting the damping, at this time, the hour hand is the end gear of the transmission chain, and its damping will act in the opposite direction on the entire transmission chain through the gear set, forming a "load constraint". When there is a gap between the driving wheel and the driven wheel, the driving wheel must first overcome the damping resistance of the driven wheel before it can drive it to rotate and convert the kinetic energy generated by the impact into heat energy.

[0039] During the operation of the mechanical watch, due to the wear between the gears, a certain amount of metal powder will be generated and scattered in the watch movement module 1, further aggravating the wear. The present invention can automatically capture the metal powder through structural settings during the operation of the watch, and automatically absorb and collect it by utilizing the movement of the piston part 703, thereby further improving the life of the watch movement module 1.

[0040] See also Figure 5 and Figure 6 As shown in FIG, the surface of the annular groove 5 is coated with viscous oil, which continuously captures and adheres the metal chips to form oil sludge containing the metal chips, thereby preventing the metal chips from spreading to other parts.

[0041] During the clockwise rotation of the hour hand driving ring 2, the contact convex portion 602 continuously scrapes the surface of the annular groove 5, so that the sludge on the surface of the annular groove 5 is accumulated in the buffer cavity 604 through the stepped groove 603. As the annular groove 5 rotates, new viscous oil will be applied when passing through the infiltration brush 609, so as to achieve capture and renewal.

[0042] like Figure 5As shown in the figure, when the watch cools down, the piston part 703 moves to the right to reset. At this time, there is negative pressure on the side of the piston part 703 away from the sealing coupling shaft 704. The negative pressure acts on the tail end cavity 611 through the connecting air nozzle 614 and the negative suction hole 613. After passing through the first one-way valve 612, the negative pressure is generated in the sludge storage cavity 605, and the sludge buffered in the buffer cavity 604 is actively sucked into the sludge storage cavity 605. In this process, the oil-proof breathable filter membrane 610 plays a role in separating oil and gas to prevent sludge from entering the first one-way valve 612. Similarly, when the piston part 703 moves to the left, there is positive pressure on the side of the piston part 703 away from the sealing coupling shaft 704, and the positive pressure can only be discharged through the second one-way valve 615. The one-way piece 607 can be opened under negative pressure or pushed open when the sludge in the buffer cavity 604 is full, as long as the supporting elastic force of the supporting elastic part 608 is not too large.
