DETAILED DESCRIPTION

[0029] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0030] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art in the technical field of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0031] Figures 1 to 9 The structure of a novel wristwatch according to one embodiment of the utility model is schematically shown.

[0032] like Figures 1 to 9 As shown, a novel wristwatch includes a watch body 7, and a display structure 1, a first power device 2, a relay flyback pointer structure 3 and a second power device 4 arranged in the watch body 7. Of course, the wristwatch mentioned here is not limited to being worn on the hand, but can also be a clock used in other scenes.

[0033] In general, in this embodiment, the display structure 1 includes a DNA helical structure 11 and a digital amplification structure 12. The first power device 2 can drive the DNA helical structure 11 and the digital amplification structure 12 to rotate. That is to say, the first power device 2 can simultaneously drive the DNA helical structure 11 and the digital amplification structure 12 to rotate synchronously. A plurality of time numbers can be assembled on the DNA helical structure 11. The digital amplification structure 12 can amplify one of the numbers and display the time through the amplified number. Specifically, the amplified number represents (the word "representation" here can also be understood as: indicating, showing) the current time (hour time).

[0034] In this embodiment, the relay flyback pointer structure 3 may include a dial display component 31, and the second power device 4 can drive the relay flyback pointer structure 3 to move. The dial display component 31 of the relay flyback pointer structure 3 can display the corresponding time, where the time displayed is minutes.

[0035] The following is a detailed description of the specific structure of each part:

[0036] like Figure 2 to Figure 7It can be seen that the DNA helical structure 11 in this embodiment includes a rotating shaft 111 and a helical frame 112. The helical frame 112 is fixed or installed on the rotating shaft 111 in a spiral manner, so that the helical frame 112 forms a structure similar to a DNA helical structure, which is novel in structure, and the helical frame 112 also has a high strength and can meet different usage requirements. In addition, a plurality of time numbers can be assembled on the rotating shaft 111, and the plurality of time numbers are arranged from left to right in the manner of 1.2.3...12, and a rotation angle is formed between two adjacent time numbers, and the rotation angle is greater than 0°. For example, a rotation angle is formed between the numbers 1 and 2, and the rotation angle is greater than 0°. The rotation angle mentioned here means that when the number 1 is facing up, the number 2 will not face up at this time, and the number 1 needs to rotate a certain angle following the rotating shaft 111 before the number 2 will face up.

[0037] In this embodiment, if Figure 2 As shown, the digital magnifying structure 12 includes a screw rod 121, a nut 122 and a magnifying glass 123. The magnifying glass 123 is connected to the nut 122. The nut 122 can move along the screw rod 121, and the magnifying glass 123 can synchronously magnify one of the numbers. Specifically, when one of the numbers is turned to face forward, the magnifying glass 123 also moves to the top of the number. The magnifying glass 123 can magnify the number, and the number indicates the current hour time.

[0038] In this embodiment, there are twelve time digits, which are 1-12 in sequence, and the rotation angle between two adjacent time digits is 225°. The rotation angle here means that when the number 1 is facing up, the rotation axis 111 needs to rotate 225°, and the number 2 will face up. Similarly, when the number 2-3 is facing up, the rotation axis 111 also needs to rotate 225°. Of course, in other embodiments, different rotation angles can be set for the digits according to actual conditions.

[0039] In addition, in this embodiment, the pitch of the screw rod 121 is 1.5 mm. When the screw rod 121 rotates 360°, the lateral distance moved by the nut 122 and the magnifying glass 123 is 1.5 mm, and the lateral distance between two adjacent time digits is 2 mm. That is, when the nut 122 and the magnifying glass 123 move 2 mm laterally, the rotating shaft 111 rotates 225°.

[0040] The specific situation is described below: In this embodiment, if Figure 3 and Figure 4As shown, the first power device 2 includes a first motor 21 and a first transmission mechanism 22. The first motor 21 can be fixedly installed in the watch body 7. The first transmission mechanism 22 is respectively connected to the rotating shaft 111 of the DNA spiral structure 11 and the lead screw 121 of the digital amplification structure 12. Therefore, the first transmission mechanism 22 can drive the rotating shaft 111 and the lead screw 121 of the DNA spiral structure 11 to rotate respectively.

[0041] The rotation speed ratio of the rotating shaft 111 and the screw rod 121 in this embodiment is 15:32. When the rotating shaft 111 rotates 225°, the screw rod 121 rotates 480°, which just corresponds to the above-mentioned rotation of the rotating shaft 111 by 225° when the nut 122 and the magnifying glass 123 move 2mm horizontally. For example, when the current time is 1 o'clock, the magnifying glass 123 is facing the position of the number 1, and the magnifying glass 123 amplifies the number 1, indicating that the current time is in the time interval of 1 hour. When the time reaches the time interval of 2, at this time, the first motor 21 is started, the first motor 21 drives the screw rod 121 to rotate 480°, the screw rod 121 drives the nut 122 to move 2mm, and the first motor 21 drives the rotating shaft 111 to rotate 225°, and the magnifying glass 123 moves from the number 1 to the number 2, and faces the number 2. Therefore, the display of the hour time is completed.

[0042] Of course, in other embodiments, the speed ratio of the rotating shaft 111 and the screw rod 121 is not limited to the above-mentioned specific numbers. The speed ratio of the rotating shaft 111 and the screw rod 121 can be set according to actual conditions, as long as the rotating shaft 111 rotates a certain angle, the screw rod 121 also rotates a corresponding angle, and the magnifying glass 123 moves to an adjacent number, and the adjacent number can be facing the magnifying glass 123.

[0043] In this embodiment, the first transmission mechanism 22 includes a first transmission gear 221, a second large transmission gear 222, a second small transmission gear 223, a third transmission gear 224, a fourth large transmission gear 225, a fourth small transmission gear 226 and a fifth transmission gear 227. The second large transmission gear 222 and the second small transmission gear 223 are coaxially connected, the fourth large transmission gear 225 and the fourth small transmission gear 226 are coaxially connected, the first transmission gear 221 is meshed with the second large transmission gear 222, the second small transmission gear 223 is meshed with the third transmission gear 224, the third transmission gear 224 is meshed with the fourth large transmission gear 225, the fourth small transmission gear 226 is meshed with the fifth transmission gear 227, the third transmission gear 224 is connected to the screw rod 121, the fifth transmission gear 227 is connected to the rotating shaft 111, and the rotating shaft 111 and the screw rod 121 rotate in the same direction.

[0044] When the first motor 21 is started, the first motor 21 can drive the other transmission gears to rotate in sequence through the first transmission gear 221, so that the rotating shaft 111 and the screw rod 121 rotate. At the same time, by setting the transmission ratio of each transmission gear, the rotating shaft 111 and the screw rod 121 can be set at the set value. Of course, in other embodiments, the number and method of the gears of the first transmission mechanism 22 can be set according to the actual situation, such as: the number of gears can be three, or four, etc.

[0045] In this embodiment, the speed ratio of the output shaft of the first motor 21 to the screw 121 is 6:1, that is, the screw rotates 4 / 3 of a circle 480° for each action, and the motor rotates 8 circles. Therefore, the first transmission mechanism 22 can play a role in deceleration.

[0046] Combination Figure 6 to Figure 9 It can be seen that the relay flyback pointer structure 3 also includes a sixth transmission gear 35. There are two dial display components 31 in this embodiment. The pointer 34 on the dial display component 31 can point to different numbers. The sixth transmission gear 35 is connected to the second power device 4. The sixth transmission gear 35 can drive the pointers 34 on the two dial display components 31 back and forth in turn to point to the numbers (the numbers on the dial body 311). Therefore, the "relay" effect is achieved in this way.

[0047] In this embodiment, if Figure 7 and Figure 8 As shown, the dial display component 31 includes a dial body 311, an arc gear 32, a zero return hairspring 33 and a pointer 34. The outer end of the zero return hairspring 33 is fixed to the watch body 7, and the inner end of the zero return hairspring 33 is fixed to the shaft core 341. The shaft core 341 is provided with a coaxially connected pointer 34. The shaft core 341 can be coaxially connected with the arc gear 32. In this embodiment, the arc gear 32 is a complete gear, and only a part of it has teeth. The toothed part can be connected with the sixth transmission gear 35. The toothless portion will not have any contact with the sixth transmission gear 35. The sixth transmission gear 35 can mesh with the arc gears 32 of the two dial display components 31 in sequence. The pointer 34 can rotate with the arc gear 32. The dial body 311 can be arranged on the arc gear 32 and the zeroing hairspring 33 in a covering manner. At the same time, numbers are arranged on the dial body 311. The pointer 34 can pass through the dial body 311 and indicate the numbers on the dial body 311 to display the time.

[0048] In this embodiment, Figure 8 and Fig. 9It can be seen that a portion of the sixth transmission gear 35 is formed with continuous long teeth, and the other portion is formed with continuous short teeth 352. The long teeth can mesh with the arc gear 32, and the short teeth 352 do not contact the arc gear 32. The arc length corresponding to the long teeth can mesh with the arc gear 32 and the number of teeth is the same.

[0049] In this embodiment, Figure 6 and Figure 7 As can be seen in the figure, the dial body 311 on the left is provided with numbers 00-30, and the dial body 311 on the right is provided with numbers 30-60.

[0050] The "relay" process of the relay flyback pointer structure 3 of the utility model is described in detail below: First, when the second power device 4 is started, the second power device 4 can drive the sixth transmission gear 35 to move through the structure of the worm gear. Figure 8 In the process, the sixth transmission gear 35 rotates counterclockwise ( Fig. 9 In the embodiment of the present invention, the sixth transmission gear 35 rotates clockwise. At this time, the long teeth of the sixth transmission gear 35 can mesh with the arc gear 32 on the left, and the arc gear 32 on the left rotates clockwise. During the clockwise rotation of the arc gear 32 on the left, the shaft core 341 can be driven to rotate synchronously, and the shaft core 341 drives the pointer 34 to rotate synchronously. The pointer 34 points to the corresponding time number on the dial body 311, such as: 00 / 05 / 10, etc., representing 00 minutes / 05 minutes / 10 minutes respectively. During the clockwise rotation of the arc gear 32 on the left, the arc gear on the right will not contact the sixth transmission gear 35, that is, the arc gear on the right will not rotate.

[0051] When the pointer 34 points to the number 30, one minute later, the long teeth of the sixth transmission gear 35 will be disengaged from the arc gear 32 on the left (i.e., not meshed). Since the return-to-zero hairspring 33 on the left is twisted and has a twisting tendency, the arc gear 32 on the left will quickly return to its original position under the action of the return-to-zero hairspring 33. At the same time, the arc gear 32 on the left drives the pointer 34 to rotate synchronously, and the pointer 34 points to the number 00. Correspondingly, the long teeth of the sixth transmission gear 35 rotate to mesh with the arc gear 32 on the right, and then the long teeth of the sixth transmission gear 35 drive the pointer 34 on the right to rotate synchronously, completing the "relay" effect. When the pointer 34 on the right points to the number 60, one minute later, the long teeth of the sixth transmission gear 35 will be disengaged from the arc gear 32 on the right (i.e., not meshed). Since the return-to-zero hairspring 33 is twisted and has a twisting tendency, the arc gear 32 on the right will quickly return to its original position under the action of the return-to-zero hairspring 33. At this time, the long teeth of the sixth transmission gear 35 are connected to the arc gear 32 on the left again to complete the minute timing of the next hour. Therefore, through the above structure, the "relay" process can be completed.

[0052] In addition, in order to allow the user to know the currently working dial display component 31 more intuitively, the following components can be set: the relay-type flyback pointer structure 3 also includes a direction display component 36, which includes a direction bar 361, a rotating tooth 362, a first slingshot 363, a second slingshot 364 and a direction plate 365. The rotating tooth 362 is coaxially connected to the sixth transmission gear 35. A rack component is arranged at the corresponding position of the direction bar 361. When the teeth on the rotating tooth 362 are engaged with the rack component, it can drive The rack component moves to the left, one end of the first slingshot 363 is fixed on the watch body 7, and a fixing pin 3612 is provided at one end of the direction bar 361. The other end of the first slingshot 363 can always be clamped by the fixing pin 3612, and the direction bar 361 is always subjected to the elastic force / or elastic tendency force of the first slingshot 363; a column pin 351 is provided on the back of the sixth transmission gear 35, and the second slingshot 364 can clamp the direction bar 361 to prevent the direction bar 361 from being pulled under the elastic force of the first slingshot 363. Of course, the pin 351 can also squeeze the second slingshot 364 so that the second slingshot 364 is separated from the direction bar 361. The direction bar 361 is pulled under the elastic force of the first slingshot 363. A display panel 3611 is provided on the direction bar 361. The display panel 3611 is coated with green fluorescent agent. Two hollow arrows are provided on the direction plate 365. The hollow arrows on the direction plate 365 point to the left and the right respectively. The display panel follows the movement of the direction bar 361 so that the green fluorescence on the display panel 3611 is displayed through one of the hollow arrows on the direction plate.

[0053] The working process of the direction display component 36 is described in detail below:

[0054] The display panel 3611 in this embodiment is coated with green fluorescent agent, so the display panel 3611 is always in the working state of displaying. The display panel 3611 can emit fluorescence, and the emitted fluorescence can be displayed through the corresponding hollow arrow on the direction plate 365. Figure 7 It can be seen that there are two hollow arrows on the left and the right. The left hollow arrow corresponds to the left dial display component 31, and the right hollow arrow corresponds to the right dial display component 31. That is to say, when the left hollow arrow displays fluorescent light, it means that the left dial display component 31 is working at this time. Correspondingly, when the right hollow arrow displays fluorescent light, it means that the right dial display component 31 is working at this time.

[0055] The rotating tooth 362 is coaxially connected to the sixth transmission gear 35, and the sixth transmission gear 35 can drive the rotating tooth 362 to rotate synchronously. Figure 8It can be seen from the figure that due to the two teeth on the rotating tooth 362, during the counterclockwise rotation of the sixth transmission gear 35 (the sixth transmission gear 35 always rotates counterclockwise), the rotating tooth 362 also always rotates counterclockwise, and the two teeth on the rotating tooth 362 can just drive the direction bar 361 to move a certain distance to the left (the distance is equal to the length of the sliding groove on the direction bar 36, the sliding groove is indicated in the figure, but there is no label, the direction bar 36 can move along the fixed pin through the sliding groove), the direction bar 361 is stuck by the second slingshot 364 and the first slingshot 363 has a tendency to drive the direction bar 361 to move to the right. At this time, the fluorescent light displayed on the display panel 3611 is displayed through the hollow arrow on the left, which means that the dial on the left is displayed. The display component 31 is working, and the long teeth of the sixth transmission gear 35 are also meshed with the arc gear 32 on the left. When the pointer 34 on the left points to the number 30, one minute later, the long teeth of the sixth transmission gear 35 will be disengaged from the arc gear 32 on the left (i.e., not meshed), and the pin 351 on the back of the sixth transmission gear 35 just squeezes the second slingshot 364, and the second slingshot 364 temporarily disengages from the direction bar 361. Since the direction bar 361 will not be stuck by the second slingshot 364, under the action of the elastic force of the first slingshot 363, the direction bar 361 moves to the right. At this time, the fluorescent light displayed on the display panel 3611 is displayed through the hollow arrow on the right, and the corresponding hollow arrow also completes the "relay". When the pointer 34 on the right points to the number 60, one minute later, the long teeth of the sixth transmission gear 35 will disengage (not mesh) from the arc gear 32 on the right, and the two teeth on the rotating teeth 362 can just drive the direction bar 361 to move a certain distance to the left. At the same time, the direction bar 361 is stuck by the second slingshot 364, preventing the direction bar 361 from moving to the right under the elastic force of the first slingshot 363, completing a cycle.

[0056] In this embodiment, the second power device 4 includes a second motor 41, a seventh transmission gear 42, an eighth transmission gear 43, a ninth transmission gear 44, a tenth transmission gear 451 and a worm 45. The seventh transmission gear 42 is connected to the second motor 41. The seventh transmission gear 42, the eighth transmission gear 43, the ninth transmission gear 44 and the tenth transmission gear 451 are meshed with each other in sequence. The tenth transmission gear 451 and the worm 45 are coaxially connected. The worm 45 is matched with a turbine 452. The turbine 452 is coaxially connected with an eleventh transmission gear 46. The eleventh transmission gear 46 is meshed with the sixth transmission gear 35. When the second motor 41 is started, the second motor 41 can sequentially drive the seventh transmission gear 42, the eighth transmission gear 43, the ninth transmission gear 44, the tenth transmission gear 451 and the worm 45 to rotate. The worm 45 drives the turbine 452 to rotate. When the turbine 452 rotates, it drives the sixth transmission gear 35 to rotate.

[0057] In this embodiment, it also includes a micro encoder 5, an adjusting component and a control module. The adjusting component includes a crown 61 and a stem 62. The crown 61 is connected to the stem 62. One end of the stem 62 is connected to the micro encoder. When the stem 62 presses the micro encoder, it can trigger the button switch of the micro encoder.

[0058] In this embodiment, after pressing the micro encoder, when the handle 61 rotates the stem 62, the stem 62 drives the encoder disk of the micro encoder 5 to rotate, so that the mechanical structure changes, and the micro encoder 5 generates a corresponding digital signal, and the digital signal control module generates a corresponding drive signal according to the digital signal, and controls the corresponding motor to rotate through the drive signal. After the rotation is completed, the micro encoder 5 is pressed again to complete the operation.

[0059] In the utility model, the display structure includes a DNA spiral structure and a digital amplification structure. The DNA spiral structure can drive the digital rotation, and the digital amplification structure will also move. The digital amplification structure amplifies a certain number and displays the time through the amplified number, that is, the number is the current time (hour). At the same time, the relay flyback pointer structure can relay the display of time through two dial display components, and the relay flyback pointer structure can display the minute time correspondingly. The overall structure is novel, and the time display method is completely different from that of traditional watches. It is essentially different from the structure of traditional watches and can meet the needs of users with different needs.

[0060] The utility model adopts two time display modes, one is a DNA spiral structure, and the other is a relay-type flyback pointer structure similar to the structure of a car dashboard. The final time expression is finally achieved through these two structures. The time display mode is novel and can meet the needs of different groups of people.

[0061] The present utility model is not limited to the above-mentioned optional implementation modes. Anyone can derive other various forms of products under the inspiration of the present utility model. However, no matter what changes are made in the shape or structure, all technical solutions that fall within the scope defined by the claims of the present utility model fall within the protection scope of the present utility model.
