Detailed implementation manners

[0035] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the drawings in the specification of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of 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.

[0036] For a better understanding of the present invention, the above content will be described in detail below in conjunction with specific embodiments.

[0037] Please refer to the attached Figure 1 - attached Figure 8 , the embodiment of the present invention provides an adjustable personalized electronic counter based on circuit board control, including: a housing 1, inside which a circuit board 3 and a display screen 2 are installed and connected to each other; a receiving switch 5, which is located on one side of the inner bottom of the housing 1 and connected to the circuit board 3; a button 4, which is installed outside the housing 1, and an adjusting mechanism 6 is arranged on the other side of the inner bottom of the housing 1. The button 4 is used to squeeze the adjusting mechanism 6 after being stressed to make it contact with the receiving switch 5. Subsequently, the receiving switch 5 generates an electrical signal and transmits it to the circuit board 3, and finally the counting information is displayed through the display screen 2.

[0038] In this embodiment, pressing the button 4 can drive the adjusting mechanism 6 to contact the receiving switch 5. Subsequently, the electrical signal generated by the receiving switch 5 will be transmitted to the circuit board 3. After being processed by the circuit board 3, the counting information will be displayed on the display screen 2, thereby driving the traditional mechanical movement.

[0039] Please refer to the appendix Figure 3 - appendix Figure 8 , the adjusting mechanism 6 includes a sleeve 601. The sleeve 601 is fixedly connected to the inner bottom of the housing 1. On both sides inside the sleeve 601, a left plate 602 and a right plate 603 are respectively slidably connected. And between the left plate 602 and the right plate 603, they are fixedly connected by a cross bar 604. One side of the left plate 602 is fixedly connected with a connecting rod 605, and the connecting rod 605 is connected to the button 4. One side of the right plate 603 is fixedly connected with a pressing rod 606. One end of the pressing rod 606 is close to the receiving switch 5. Inside the sleeve 601, there is a coil 607. One side of the coil 607 is connected to the circuit board 3, and the coil 607 is located between the left plate 602 and the right plate 603. Inside the left plate 602, there is a magnet 608. The coil 607 is used to generate magnetic force after being powered on. The magnetic poles on the adjacent sides between the magnet 608 and the coil 607 are the same. Inside the housing 1, a storage battery 7 is fixedly connected. The storage battery 7 is used to supply power to the coil 607, the receiving switch 5, the display screen 2 and the circuit board 3.

[0040] In this embodiment, pressing the button 4 will drive the left plate 602 and the right plate 603 to approach the receiving switch 5. At this time, the connecting rod 605 and the pressing rod 606 will also approach the receiving switch 5 together. And at this time, the left plate 602 will also drive the magnet 608 to approach the coil 607. Therefore, when the coil 607 is powered on, it will generate magnetic force. And the magnetic poles on the adjacent sides of the magnet 608 and the coil 607 are the same. Using the principle of like poles repelling each other, there will be a resistance when pressing the button 4. And by adjusting the magnitude of the current flowing through the coil 607, the magnitude of the magnetic force generated by the coil 607 can be adjusted, and then the resistance received by the magnet 608 when approaching the coil 607 can be adjusted, so as to achieve the purpose of adjusting the pressing touch feeling of the button 4.

[0041] Please refer to the appendix Figures 1 - 4 and Figures 9 - 11 , on the top of one side of the outer wall of the housing 1, a support plate 8 is rotatably connected. On the bottom of one side of the outer wall of the housing 1, a support leg 9 is rotatably connected. One side of the support leg 9 is fixedly connected with a cross plate 10. In the middle of the cross plate 10, there is a plug-in column 11. At the bottom of the support plate 8, a plug-in plate 12 is rotatably connected. The plug-in column 11 penetrates through the plug-in plate 12. In the middle of the support plate 8, a support foot 13 is slidably connected. On both sides of the inner bottom of the support foot 13, a top block 14 is slidably connected. Between the two top blocks 14, there is a spring 15. On the upper middle parts of both sides of the inner wall of the support plate 8, a card slot 16 is opened. And the adjacent sides of the two top blocks 14 are respectively located in the two card slots 16. The bottom of the support foot 13 is rotatably connected to the plug-in plate 12.

[0042] In this embodiment, the support plate 8, the support plate 8 and the support leg 9 can support the housing 1, and the support plate 8, the housing 1 and the support leg 9 can be unfolded in a triangular shape. Therefore, the stability of the support of the housing 1 by this device can be improved. At the same time, after pulling out the pull-out foot 13, the top blocks 14 on both sides inside the foot 13 can be driven to move out of the card slot 16 and approach each other, so that the spring 15 can be compressed. When the top block 14 coincides with the position of the card slot 16 again, the spring 15 can push the top block 14 out so that it enters the card slot 16, thereby adjusting the combined length between the foot 13 and the support plate 8. When the combined length of the two changes, the ratio of their lengths to the length of the support leg 9 will also change at any time, thereby adjusting the pitch angle of the housing 1 and the display screen 2 during use.

[0043] Please refer to the appendix Figures 1 - 4 and Figures 9 - 11 , the insertion column 11 is rotatably connected to the middle of the cross plate 10, and a through hole is opened at the top of the support plate 8, and a threaded groove is opened at the top of one side of the housing 1. The insertion column 11 passes through the through hole and is threadedly connected to the threaded groove. A limiting ring 17 is fixedly connected to one side of the outer wall of the insertion column 11. The diameter of the limiting ring 17 is larger than the diameter of the insertion column 11, and the limiting ring 17 is rotatably connected to the inside of the cross plate 10. An anti-slip pad 18 is fixedly connected to one side of the cross plate 10, and the anti-slip pad 18 is made of rubber. A groove is opened inside one side of the button 4, and one end of the connecting rod 605 is located in the groove, and the connecting rod 605 is inserted into the groove.

[0044] In this embodiment, after use, first separate the insertion plate 12 from the insertion column 11, then rotate the support plate 8 so that it contacts the housing 1, and then rotate the support leg 9 so that the cross plate 10 contacts the support plate 8. At this time, rotate the insertion column 11 and screw it into the threaded groove on the outer wall of the housing 1. At this time, the housing 1, the support leg 9 and the support plate 8 can form a whole, thereby avoiding the phenomenon of scattering and improving the convenience of carrying this device.

[0045] Working principle: When in use, first rotate the insertion column 11 to move it out of the threaded groove, then first rotate the support leg 9 to move it away from the support plate 8, then rotate the support plate 8 away from the housing 1, then pull the support plate 8 to drive the housing 1 to rotate along one side of the support leg 9, and then dial the insertion plate 12 to put it on the outside of the insertion column 11. At this time, a triangular structure is formed between the support leg 9, the housing 1 and the support plate 8, thereby supporting the housing 1 and the display screen 2;

[0046] When counting is required, pressing the button 4 pushes the connecting rod 605, the left plate 602, the cross bar 604, the right plate 603, and the extrusion rod 606 to slide inside the sleeve 601. Thus, the extrusion rod 606 can be made to approach the receiving switch. When the extrusion rod 606 contacts the receiving switch 5, the receiving switch 5 will generate an electrical signal at this time and transmit the electrical signal to the circuit board 3. After the circuit board 3 processes the signal, the signal can be displayed on the display screen 2, thereby displaying the counting information. Moreover, when the left plate 602 approaches the receiving switch 5, the circuit board 3 can transmit the power of the storage battery 7 to the coil 607. When the coil 607 is energized, it will generate a magnetic force, and the magnetic poles on the adjacent sides between the coil 607 and the magnet 608 are the same. Using the principle of like poles repelling each other, when the button 4 presses the connecting rod 605 and the left rod approaches the receiving switch 5, it will be subject to magnetic resistance. By adjusting the magnitude of the current flowing through the coil 607, the magnitude of the magnetic force generated by the coil 607 can be changed. Therefore, the magnitude of the magnetic resistance received by the left plate 602 when the button 4 is pressed can be adjusted, and thus the purpose of adjusting the pressing touch feeling of the button 4 can be achieved;

[0047] Moreover, during use, by pulling the support feet 13, they can slide inside the straight plate. Therefore, when the top blocks 14 are moved out of the card slots 16 inside the support plate 8, the top blocks 14 on both sides inside the support feet 13 will approach each other and compress the spring 15. When the top blocks 14 coincide with the card slots 16 again, the elastic force of the spring 15 will drive the top blocks 14 on both sides to move away from each other, and then the top blocks 14 will be squeezed inside the card slots 16. Therefore, the combined length of the support feet 13 and the support plate 8 can be adjusted, and then the ratio of the combined length of the two to the length of the support legs 9 can be adjusted, thereby changing the pitching angle of the housing 1 and the display screen 2;

[0048] After use, first separate the plug-in board 12 from the plug-in post 11, then rotate the support plate 8 to make it contact the housing 1, and then rotate the support legs 9 to make them contact the support plate 8. At this time, the plug-in post 11 will pass through the through hole at the top of the support plate 8. Subsequently, rotating the plug-in post 11 can screw it into the threaded groove, thereby reducing the distance between the cross plate 10 and the housing 1. The cross plate 10 squeezes the support plate 8, so that the support legs 9, the cross plate 10, the support plate 8, and the housing 1 form a whole, preventing the support plate 8 and the support legs 9 from separating from the housing 1 and improving the portability and convenience.

[0049] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
