Description

Technical Field

[0001] The invention relates to the field of induction code computers, in particular to a magnetic induction code computer for bicycles. Background Art

[0002] A magnetic induction meter for bicycles is an electronic device specially used to calculate the speed and mileage of bicycle riding. Its principle is that when the magnet installed on the wheel spoke passes the sensor on the front fork as the wheel rotates, an induced current will be generated in the coil. This current change is captured by the induction coil and transmitted to the meter host. The meter host calculates the number of wheel rotations by processing these signals, and then combines the pre-set wheel circumference data to calculate the speed and distance of the bicycle.

[0003] During the use of the computer, the induction magnet needs to be installed on the tire banner. For example, the utility model patent with application number CN202123026713.X discloses a bicycle computer sensing device, including an upper cover and a lower cover detachably connected to the upper cover; the lower cover is provided with a connecting column; the connecting column is provided with a slot; the side of the connecting column is provided with a through hole connected to the slot; the upper cover is provided with a pressing column for inserting in the slot; the lower cover is provided with a magnet; the lower cover is provided with a first placement groove connected to the slot and a second placement groove connected to the slot at the bottom of the connecting column.

[0004] In the above case, since bicycle banners are usually made of metal steel wire with a relatively smooth surface, it is difficult for the induction magnet to stably attach to the banner. In addition, during the movement of the bicycle, the induction magnet is easily shifted due to the vibration of the bicycle body, resulting in the sensor failing to capture the induction magnet, which in turn leads to measurement failure.

[0005] Therefore, the present invention proposes a magnetic induction code computer for bicycle to solve the above problems. Summary of the invention

[0006] In order to achieve the above purpose, the technical solution adopted by the present invention is: a magnetic induction code computer for bicycles, comprising: An upper clamping seat and a lower clamping seat, wherein the upper clamping seat and the lower clamping seat are fixedly connected to the surface of the wheel axle through a fixing bolt; A lifting and adjusting frame, the bottom end of which is fixedly connected to the top end of the upper clamping seat; A first clamping block, wherein the first clamping block is fixedly connected to the top of the lifting and adjusting frame; A bolt, wherein a slot is provided at the end of the bolt, and the slot is used to insert the steel wire banner; A second clamping block, wherein the second clamping block is clamped with the bolt thread, and an electromagnet is fixedly connected to an end of the second clamping block; Specifically, in the prior art, since bicycle banners are usually metal steel wires with a relatively smooth surface, it is difficult for the induction magnet to stably attach to the banners. In addition, during the movement of the bicycle, the induction magnet is easily shifted in position due to the vibration of the bicycle body, resulting in the sensor failing to capture the induction magnet, which in turn causes measurement failure.

[0007] This technical solution can solve the above problems, and the specific operations are as follows: First, adjust the tire position, find a suitable steel wire banner, insert the steel wire banner into the slot, and then determine the position of the second clamping block. Then, fix the upper clamping seat and the lower clamping seat to the surface of the wheel axle through the fixing bolts, and then thread the second clamping block with the first clamping block. Finally, adjust the height position of the electromagnetic block through the lifting adjustment frame so that the sensor of the peripheral device can capture the electromagnet. During riding, the wheel axle drives the upper and lower clamping seats to rotate together, so that the lifting and adjusting frame drives the first clamping block, the second clamping block and the electromagnet to rotate. At this time, the electromagnet is limited in both radial and axial directions, which helps to avoid the problem of the electromagnet's position being offset during the bicycle's travel, and helps to improve the success rate of the sensor capturing the electromagnet.

[0012] Scenario 2: When the bicycle is running at a low speed, the counterweight block is subjected to the centrifugal force, so that the counterweight block slides along the side wall of the lifting adjustment frame, and the sliding pin slides along the inclined groove, wherein the counterweight block is slidably connected to the side wall of the sliding frame. Driven by the inclined groove, the U-shaped connecting frame moves away from the side wall of the first card block, so that the hook pulls the connecting block to move in the direction of the first card block, so that the first spring is pulled and the second spring is compressed, so that the second spring applies pressure on the second card block in the direction of the first card block, thereby improving the stability of the connection between the second card block and the first card block, which is beneficial to avoid the second card block from loosening from the first card block due to vibration during the driving of the bicycle, and reduces the possibility of the electromagnet deviating from the specified position or even falling off.

[0013] Scenario three: When the bicycle is running at high speed, the inertial force received by the counterweight block increases. Compared with the low-speed state, the counterweight block moves farther along the inclined groove, so that the U-shaped pushing frame is farther away from the first block, and the hook pulls the connecting block to move farther.

During riding, the wheel shaft drives the upper clamping seat and the lower clamping seat to rotate together, so that the lifting adjustment frame drives the first clamping block, the second clamping block and the electromagnet to rotate. At this time, the electromagnet is limited in both radial and axial directions, which helps to avoid the problem of the position of the electromagnet being offset during the riding of the bicycle, and helps to improve the success rate of the sensor capturing the electromagnet.

[0018] 2. The present invention provides a hook and a connecting block. During the running of the bicycle, the U-shaped connecting frame is pulled by the pulling assembly, so that the hook pulls the connecting block to move in the direction of the first clamping block, so that the first spring is pulled and the second spring is compressed, so that the second spring applies pressure on the second clamping block in the direction of the first clamping block, thereby improving the stability of the connection between the second clamping block and the first clamping block, which is beneficial to avoid the second clamping block from loosening with the first clamping block due to vibration during the running of the bicycle, and reduces the possibility of the electromagnet deviating from the specified position or even falling off.

[0019] 3. The present invention arranges a counterweight block, a drive plate and an inclined slot.

DETAILED DESCRIPTION

[0022] The following description is used to disclose the present invention so that those skilled in the art can implement the present invention. The preferred embodiments described below are only examples, and those skilled in the art may think of other obvious variations.

[0023] like Figures 1 to 10 A magnetic induction computer for a bicycle, comprising: An upper clamping seat 3 and a lower clamping seat 4, wherein the upper clamping seat 3 and the lower clamping seat 4 are fixedly connected to the surface of the wheel shaft 1 via a fixing bolt; A lifting and adjusting frame, the bottom end of which is fixedly connected to the top end of the upper clamping seat 3; A first clamping block 7, the first clamping block 7 is fixedly connected to the top of the lifting and adjusting frame; The bolt 8 has a slot 801 at the end thereof, and the slot 801 is used to insert the steel wire banner 2; A second clamping block 9, the second clamping block 9 is threadedly clamped with the bolt 8, and an electromagnet 10 is fixedly connected to the end of the second clamping block 9; Specifically, in the prior art, since bicycle banners are usually metal steel wires with a relatively smooth surface, it is difficult for the induction magnet to stably attach to the banners. In addition, during the movement of the bicycle, the induction magnet is easily shifted in position due to the vibration of the bicycle body, resulting in the sensor failing to capture the induction magnet, which in turn causes measurement failure.

[0024] This technical solution can solve the above problems, and the specific operations are as follows: First, adjust the tire position, find a suitable steel wire banner 2, first insert the steel wire banner 2 into the slot 801, so as to determine the position of the second clamping block 9, then fix the upper clamping seat 3 and the lower clamping seat 4 to the surface of the wheel shaft 1 through the fixing bolts, then thread the second clamping block 9 and the first clamping block 7, and finally adjust the height position of the electromagnetic block through the lifting adjustment frame so that the external sensor can capture the electromagnet 10; During riding, the wheel axle 1 drives the upper clamping seat 3 and the lower clamping seat 4 to rotate together, so that the lifting and adjusting frame drives the first clamping block 7, the second clamping block 9 and the electromagnet 10 to rotate. At this time, the electromagnet 10 is limited in both radial and axial directions, which helps to avoid the problem of position deviation of the electromagnet 10 during the driving of the bicycle, and helps to improve the success rate of the sensor capturing the electromagnet 10.

[0025] As an optional implementation of the lifting and adjusting frame, the lifting and adjusting frame includes: The bracket 5 has a bottom end fixedly connected to the top of the upper holder 3, and a first buckle groove 501 is formed on the top of the bracket 5; The sliding frame 6, the bottom end of the sliding frame 6 is slidably connected to the top side wall of the bracket 5, and a plurality of second buckle grooves 601 are arranged in an array on the bottom side wall of the sliding frame 6, and the first buckle groove 501 and the second buckle groove 601 are connected and limited by a threaded pin; Specifically, by setting the bracket 5 and the sliding frame 6, during the process of installing the electromagnet 10, the radial position of the electromagnet 10 is adjusted by adjusting and pushing the sliding frame 6 until the external sensor can capture the electromagnet 10, and then the position of the sliding frame 6 is limited by the threaded pin, thereby limiting the radial position of the electromagnet 10, which is beneficial to improve the stability of the radial position of the electromagnet 10.

[0026] As a further embodiment of the present invention, it also includes: A U-shaped connecting frame 11, both sides of which are slidably connected to the outer side wall of the first clamping block 7, and two first springs 12 are symmetrically fixedly connected between the U-shaped connecting frame 11 and the first clamping block 7; A hanging block 13, the hanging block 13 is slidably connected to the outer wall of the second clamping block 9, and two second springs 14 are symmetrically fixedly connected between the hanging block 13 and the second clamping block 9; Two rotating frames 15, one end of each rotating frame 15 is rotatably connected to the outer wall of the U-shaped connecting frame 11, and the other end of each rotating frame 15 is fixedly connected to a hook 16, which is hung on the hanging block 13; A pulling assembly is used for the U-shaped connecting frame 11, so that the hook 16 pulls the hanging block 13 to move in the direction of the first card block 7, so that the second spring 14 applies pressure to the second card block 9 in the direction of the first card block 7, thereby increasing the stability of the connection between the second card block 9 and the first card block 7; Specifically, by providing the hook 16 and the connecting block 13, during the driving of the bicycle, the U-shaped connecting frame 11 is pulled by the pulling assembly, so that the hook 16 pulls the connecting block 13 to move in the direction of the first clamping block 7, so that the first spring 12 is pulled and the second spring 14 is compressed, so that the second spring 14 applies pressure on the second clamping block 9 in the direction of the first clamping block 7, thereby improving the stability of the connection between the second clamping block 9 and the first clamping block 7, which is beneficial to avoid the second clamping block 9 from loosening on the first clamping block 7 due to vibration during the driving of the bicycle, and reduces the possibility of the electromagnet 10 deviating from the specified position or even falling off.

[0027] As a further embodiment of the present invention, the pulling assembly comprises: Two driving plates 26, the two driving plates 26 are symmetrically fixedly connected to the two side walls of the U-shaped connecting frame 11, and the side walls of the driving plates 26 are provided with oblique grooves 27; A counterweight block 28 is slidably connected to the side wall of the lifting and adjusting frame. Sliding pins 29 are symmetrically fixedly connected to both sides of the counterweight block 28. The sliding pins 29 are slidably connected in the inclined slots 27. It should be noted that the gravity of the counterweight 28 is less than the sum of the elastic resistances of the first spring 12 , the second spring 14 , the third spring 31 and the arc spring 18 ; Scenario 1: When the bicycle is not moving, the weight of the counterweight 28 itself cannot overcome the elastic resistance of the first spring 12, the second spring 14, the third spring 31 and the arc spring 18, so that the hook 16 cannot pull the hanging block 13, thereby facilitating manual disassembly of the second clamping block 9 and the electromagnet 10.

[0028] Scenario 2: When the bicycle is running at a low speed, the counterweight 28 is subjected to the centrifugal force, so that the counterweight 28 slides along the side wall of the lifting and adjusting frame, and the sliding pin 29 slides along the inclined groove 27, wherein the counterweight 28 is slidably connected to the side wall of the sliding frame 6. Driven by the inclined groove 27, the U-shaped connecting frame 11 moves away from the side wall of the first clamping block 7, so that the hook 16 pulls the hanging block 13 to move toward the first clamping block 7, so that the first spring 12 is pulled and the second spring 14 is compressed, so that the second spring 14 applies pressure to the second clamping block 9 in the direction of the first clamping block 7, thereby improving the stability of the connection between the second clamping block 9 and the first clamping block 7, which is conducive to avoiding the loosening of the second clamping block 9 and the first clamping block 7 due to vibration during the driving of the bicycle, and reducing the possibility of the electromagnet 10 deviating from the specified position or even falling off.

[0029] Scenario three: When the bicycle is running at high speed, the inertial force received by the counterweight block 28 increases. Compared with the low-speed state, the counterweight block 28 moves farther along the inclined groove 27, thereby making the U-shaped pushing frame farther away from the first block 7. The longer the hook 16 pulls the connecting block 13 to move, the greater the compression force of the second spring 14, and then the second spring 14 applies greater pressure on the second block 9 in the direction of the first block 7, thereby further improving the stability of the connection between the second block 9 and the first block 7.

[0030] As a further embodiment of the present invention, it also includes: An arc-shaped limit plate 17, the arc-shaped limit plate 17 is slidably connected in the hook 16, and an arc-shaped spring 18 is fixedly connected between the arc-shaped limit plate 17 and the hook 16; A pushing component, which is used to push the arc-shaped limiting plate 17 to slide, so that the arc-shaped limiting plate 17 extends from the hook 16 to lock the hanging block 13 in the hook 16, so as to increase the stability of the connection between the hook 16 and the hanging block 13; Specifically, by setting an arc-shaped limit plate 17, during the movement of the bicycle, the arc-shaped limit plate 17 is pushed to slide by the pushing assembly, so that the arc-shaped limit plate 17 extends from the hook 16, so that the hook 16 is locked to the hanging block 13, thereby improving the stability of the connection between the hook 16 and the hanging block 13, and preventing the hook 16 and the hanging block 13 from falling off during the movement of the bicycle.

[0031] As a further embodiment of the present invention, the pushing component comprises: The chamber 19 is provided in the rotating frame 15, and one end of the chamber 19 is communicated with the interior of the hook 16; A through slot 20, which is formed on the side wall of the end of the rotating frame 15 and communicates with the chamber 19; An L-shaped compression frame 22, one end of which is slidably connected in the chamber 19, and the other end of which passes through the through slot 20 and is slidably connected to the side wall of the through slot 20; A stopper 21, which is fixedly connected to the outer wall of the first clamping block 7 at a position corresponding to the L-shaped compression frame 22; Specifically, by providing the L-shaped compression frame 22, when the bicycle moves and the counterweight block 28 moves away from the center of the circle along the sliding frame 6, the U-shaped connecting frame 11 drives the rotating frame 15 to move. Under the blocking action of the block 21, the L-shaped compression frame 22 slides along the through groove 20, so that the gas in the cavity is compressed. Under the action of the air pressure, the arc-shaped limit plate 17 slides and extends from the hook 16, so that the hook 16 is locked to the hanging block 13, thereby improving the stability of the connection between the hook 16 and the hanging block 13, and preventing the hook 16 and the hanging block 13 from falling off during the movement of the bicycle. In addition, the faster the bicycle travels, the farther the L-shaped compression frame 22 moves, so that the arc-shaped limit plate 17 extends longer, further improving the stability of the connection between the hook 16 and the hanging block 13.

[0032] As a further embodiment of the present invention, it also includes: The mounting groove 23 is provided on the outer wall of the first clamping block 7. Two arc-shaped clamping jaws 24 are symmetrically connected to the mounting groove 23 for rotation. The ends of the arc-shaped clamping jaws 24 are fixedly connected with protrusions 25. The flip driving assembly is used to drive the arc-shaped clamping jaw 24 to rotate, so that the end of the arc-shaped clamping jaw 24 is close to the steel wire banner 2 and squeezes the steel wire banner 2, so that the steel wire banner 2 applies pressure on the second clamping block 9 in the direction of the first clamping block 7, thereby increasing the stability of the connection between the second clamping block 9 and the first clamping block 7; Specifically, by setting an arc-shaped clamp, during the running of the bicycle, by flipping the drive assembly, the end of the arc-shaped clamp 24 is close to the steel wire banner 2 and squeezes the steel wire banner 2, and the steel wire banner 2 is squeezed by the protrusion 25, while the steel wire banner 2 is fixed, so that the steel wire banner 2 applies pressure to the second clamp block 9 in the direction of the first clamp block 7, further increasing the stability of the connection between the second clamp block 9 and the first clamp block 7.

[0033] As a further embodiment of the present invention, the flip drive assembly comprises: A folding push frame 30, the folding push frame 30 is slidably connected in the second clamping block 9, the top of the folding push frame 30 is fixedly connected to the bottom of the hanging block 13, the bottom of the folding push frame 30 is slidably connected with a rack 32, and the rack 32 and the bracket 5 of the folding push frame 30 are fixedly connected with a third spring 31; A driving gear 33, the driving gear 33 is coaxially fixed with the arc-shaped clamping jaw 24, and the driving gear 33 is meshed with the rack 32; Specifically, by setting a driving gear 33 and a rack 32, during the running of the bicycle, the connecting block 13 is pulled by the hook 16 to move toward the first block 7, so that the folding push frame 30 pushes the rack 32 to move, so that the rack 32 engages with the gear, and the arc-shaped clamping claw 24 flips, and the end of the arc-shaped clamping claw 24 approaches the steel wire banner 2 and squeezes the steel wire banner 2. The steel wire banner 2 is squeezed by the protrusion 25, so that the steel wire banner 2 applies pressure on the second block 9 in the direction of the first block 7, further increasing the stability of the connection between the second block 9 and the first block 7.

[0034] Working principle of the present invention: First, adjust the tire position, find a suitable steel wire banner 2, first insert the steel wire banner 2 into the slot 801, so as to determine the position of the second clamping block 9, then fix the upper clamping seat 3 and the lower clamping seat 4 to the surface of the wheel shaft 1 through the fixing bolts, then thread the second clamping block 9 and the first clamping block 7, and finally adjust the height position of the electromagnetic block through the lifting adjustment frame so that the external sensor can capture the electromagnet 10; Scenario 1: When the bicycle is not moving, the weight of the counterweight 28 cannot overcome the elastic resistance of the first spring 12, the second spring 14, the third spring 31 and the arc spring 18, so that the hook 16 cannot pull the hook block 13, thereby facilitating manual disassembly of the second clamping block 9 and the electromagnet 10; Scenario 2: When the bicycle is running at a low speed, the counterweight 28 is subjected to the centrifugal force, so that the counterweight 28 slides along the side wall of the lifting adjustment frame, so that the sliding pin 29 slides along the inclined slot 27, wherein the counterweight 28 is slidably connected to the side wall of the sliding frame 6, and driven by the inclined slot 27, the U-shaped connecting frame 11 is moved away from the side wall of the first clamping block 7, so that the hook 16 pulls the hanging block 13 to move in the direction of the first clamping block 7, so that the first spring 12 is pulled and the second spring 14 is compressed, so that the second spring 14 applies pressure to the second clamping block 9 in the direction of the first clamping block 7, thereby improving the stability of the connection between the second clamping block 9 and the first clamping block 7, which is conducive to avoiding the loosening of the second clamping block 9 and the first clamping block 7 due to vibration during the running of the bicycle, and reducing the possibility of the electromagnet 10 deviating from the specified position or even falling off; Scenario 3: When the bicycle is running at high speed, the inertial force received by the counterweight 28 increases. Compared with the low-speed state, the counterweight 28 moves farther along the inclined slot 27, so that the U-shaped pushing frame is farther away from the first clamping block 7, and the hook 16 pulls the connecting block 13 to move farther, and the compression force of the second spring 14 increases, and then the second spring 14 applies greater pressure on the second clamping block 9 in the direction of the first clamping block 7, thereby further improving the stability of the connection between the second clamping block 9 and the first clamping block 7; In addition, during the entire driving process of the bicycle, the wheel axle 1 drives the upper clamping seat 3 and the lower clamping seat 4 to rotate together, so that the lifting and adjusting frame drives the first clamping block 7, the second clamping block 9 and the electromagnet 10 to rotate. At this time, the electromagnet 10 is limited in both radial and axial directions, which is conducive to avoiding the problem of position deviation of the electromagnet 10 during the driving of the bicycle, and is conducive to improving the success rate of the sensor capturing the electromagnet 10.
