Description

Technical Field

[0001] The utility model relates to the field of bicycles, in particular to an electromagnetic locking pedal for a bicycle. Background Art

[0002] Many beginner cyclists have many blind spots when it comes to cycling equipment, but they hope to improve their cycling skills through good equipment, such as clipless pedals that lock cycling shoes and bicycle pedals together.

[0003] Most existing cleats are mechanical. Even more common than being unable to remove shoes, a novice rider who rides with cleats on is prone to "zero-speed falls." This literally means falling off the bike the moment they put on the cleats. Zero speed is different from speed; the rider's only balance is on the two tires, making a sideways fall very likely.

[0004] In addition, the way to unlock the mechanical cleats is to twist the ankle outward, but such an action may be forgotten in an emergency, resulting in the inability to detach from the bike, because it is not a habitual action of normal people.

[0005] This shows that existing mechanical pedal locks have significant safety risks. Summary of the Invention

[0006] The technical problem to be solved by the utility model is to overcome the defects of the prior art and provide a bicycle electromagnetic pedal lock, which can lock and unlock conveniently, quickly and safely, and can also convert the mechanical energy of the bicycle pedal rotation into electrical energy to power the electromagnet.

[0007] In order to solve the above technical problems, the technical solution of the utility model is: a bicycle electromagnetic pedal lock, comprising:

[0008] Cleats, for installation on cycling shoes;

[0009] A base, for mounting on a bicycle pedal;

[0010] an electromagnet, mounted on the base, for attracting the locking piece when energized;

[0011] a generator, mounted on the base and connected to the pedal rod of the bicycle, for converting the rotational mechanical energy of the pedal rod into electrical energy;

[0012] a battery, mounted on the base, for storing the electrical energy converted by the generator and supplying power to the electromagnet;

[0013] The control switch is used to control the power supply and power loss of the electromagnet.

[0014] In order to further make the lock pedal more secure after locking, the lock piece is a permanent magnetic base plate, and the lower surface of the permanent magnetic base plate is provided with an embedding hole, and the embedding hole is embedded with a permanent magnet.

[0015] Further providing a reasonable number and layout of permanent magnets and electromagnets, wherein three permanent magnets and three electromagnets are respectively configured, and each electromagnet corresponds to one permanent magnet; wherein,

[0016] One electromagnet is arranged at the middle position of the front end portion of the base, and the other two electromagnets are arranged at both sides of the rear end portion of the base.

[0017] In order to facilitate the installation of the cleat on the cycling shoe, the permanent magnetic base plate is provided with a mounting hole, and the mounting hole has a downward supporting surface; wherein,

[0018] The mounting hole is provided with a gasket, and the upper surface of the gasket is used to abut against the supporting surface.

[0019] Further providing a reasonably compact base structure, wherein the base and the bicycle pedal are integrally formed; or the bicycle pedal is used as the base; wherein,

[0020] The generator, the battery and the electromagnet are all installed in the base, and the adsorption end of the electromagnet is exposed from the side of the base facing the locking plate.

[0021] Furthermore, the bicycle electromagnetic pedal lock also includes a main control board, which is installed on the base. The main control board is respectively connected to the control switch and the circuit switch on the power supply circuit of the electromagnet, and is used to control the opening and closing of the circuit switch according to the signal of the control switch.

[0022] In order to further unlock the pedal immediately in emergency abnormal situations such as side falls and collisions, the bicycle electromagnetic pedal lock also includes a detection element, which is installed on the base and connected to the main control board. The main control board is also used to control the circuit switch to disconnect when the detection element detects an abnormal signal.

[0023] Possible types of detection elements are further provided, which are balance detection elements and / or angle sensors.

[0024] In order to further facilitate the alignment of the locking piece and the base, a limiting component is provided between the base and the locking piece.

[0025] A specific structure of a limiting assembly is further provided, wherein the limiting assembly includes at least two protrusions arranged on the base and at least two recesses arranged on the locking plate, each protrusion corresponds to a recess and is used to be embedded in the corresponding recess.

[0026] By adopting the above technical solution, the present invention achieves locking between the base and the locking plate by energizing the electromagnet and unlocking the base and the locking plate by de-energizing the electromagnet. This is convenient and saves time, effectively preventing falls caused by locking, and also facilitates unlocking in emergencies. The control switch that controls the energization and de-energization of the electromagnet can be installed on the bicycle handlebar or other convenient location for riding, further improving convenience and safety, and reducing accidents caused by the inability of mechanical pedal locks to flexibly lock and unlock.

[0033] In order to make the contents of the present invention more clearly understood, the present invention is further described in detail below based on specific embodiments in conjunction with the accompanying drawings.

[0034] Example 1

[0035] like Figures 1 to 5 As shown, a bicycle electromagnetic pedal lock includes:

[0036] Cleat 1, used for installation on cycling shoes;

[0037] A base 3, for mounting on a bicycle pedal;

[0038] The electromagnet 4 is mounted on the base 3 and is used to attract the permanent magnet 2 when powered;

[0039] A generator 5 is mounted on the base 3 and connected to a pedal rod 6 of a bicycle pedal, and is used to convert the rotational mechanical energy of the pedal rod 6 into electrical energy;

[0040] The battery 7 is mounted on the base 3 and is used to store the electrical energy converted by the generator 5 and to supply power to the electromagnet 4;

[0041] The control switch is used to control the power supply of the electromagnet 4.

[0042] Specifically, this embodiment achieves locking between the base 3 and the locking plate 1 by energizing the electromagnet 4, and unlocking the base 3 and the locking plate 1 by de-energizing the electromagnet 4. This is convenient and saves time, effectively preventing falls caused by locking the bicycle, and also facilitates unlocking in emergencies. The control switch that controls the energization and de-energization of the electromagnet 4 can be installed on the bicycle handlebar or other convenient location for riding, further improving convenience and safety, and reducing accidents caused by the inability to flexibly lock and unlock mechanical pedals. The utility model also utilizes the combination of a generator 5 and a battery 7 to convert the mechanical energy generated during the rotation of the bicycle pedal rod 6 into electrical energy to power the electromagnet 4, eliminating the need for separate charging or battery replacement.

[0043] It should be noted that after the electromagnet 4 is energized, the electromagnet 4 absorbs the lock plate 1 to achieve locking, and the suction force between the two is greater than the pulling force of the human leg when the lock pedal is pulled upward, thereby ensuring that there is no risk of unlocking.

[0044] In this embodiment, to ensure strong attraction between the electromagnet 4 and the locking plate 1, the locking plate 1 may be, but is not limited to, a permanent magnetic base plate having an embedding hole provided on its lower surface, in which the permanent magnet 2 is embedded. The permanent magnet 2 is a strong permanent magnet. This ensures a secure adsorption between the locking plate 1 and the base 3.

[0045] The number of electromagnets 4 and permanent magnets 2 can be multiple, respectively. Figures 1 to 5 In the example shown, there are three permanent magnets 2 and three electromagnets 4, each electromagnet 4 corresponding to one permanent magnet 2;

[0046] One electromagnet 4 is disposed at a middle position of the front end portion of the base 3 , and the other two electromagnets 4 are disposed at both sides of the rear end portion of the base 3 .

[0047] In this way, there are multiple adsorption points between the locking piece 1 and the base 3, which can ensure that the base 3 firmly adsorbs the locking piece 1.

[0048] In this embodiment, the entire locking piece 1 may be configured as a strong permanent magnet; the locking piece 1 itself may also be made of a material that cannot be magnetically attracted, but the locking piece 1 may be embedded with a strong permanent magnet.

[0049] Example 2

[0050] Based on the first embodiment, Figure 1 and Figure 2 As shown, the base 3 and the bicycle pedal are integrally formed; or the bicycle pedal is used as the base 3; wherein,

[0051] The generator 5 , the battery 7 and the electromagnet 4 are all installed in the base 3 , and the adsorption end of the electromagnet 4 is exposed on the side of the base 3 facing the locking piece 1 .

[0052] In this way, the compactness of the structure can be ensured, and the trouble of installing the base 3 on the bicycle pedal can be avoided.

[0053] Example 3

[0054] On the basis of Example 1 or Example 2, Figure 3 As shown, the bicycle electromagnetic pedal lock also includes a main control board 8, which is installed on the base 3. The main control board 8 is respectively connected to the circuit switch on the controlled switch and the power supply circuit of the electromagnet 4, and is used to control the opening and closing of the circuit switch according to the signal of the control switch.

[0055] Like this, the control switch can be installed on the bicycle handlebar, certainly, also can be installed in other position of convenient operation.Main control board 8 can be connected wirelessly with the control switch, has avoided the trouble of arranging electric wire or traction line on bicycle frame.

[0056] Example 4

[0057] Based on the third embodiment, Figure 3 As shown, the bicycle electromagnetic pedal lock further includes a detection element, which is mounted on the base 3 and connected to the main control board 8. The main control board 8 is also used to control the circuit switch to disconnect when the detection element detects an abnormal signal.

[0058] Specifically, when the bicycle experiences an emergency or abnormal situation such as a fall or collision, the detection element can detect the abnormal situation, and the main control board 8 can promptly control the pedal lock to unlock, so that the cycling shoe is promptly released from the bicycle pedal to avoid further injury. The detection element is a balance detection element and / or an angle sensor 9.

[0059] Example 5

[0060] Based on any one of the embodiments 1 to 4, Figure 4 and Figure 5 As shown, the permanent magnetic base plate is provided with a plurality of mounting holes 11, and the bolts pass through the mounting holes 11 and are threadedly connected to the cycling shoes.

[0061] A downward supporting surface 111 is provided in the mounting hole 11 . A gasket 10 is configured for each mounting hole 11 . The upper surface of the gasket 10 abuts against the supporting surface 111 , and the big head of the bolt can be completely sunk into the mounting hole 11 .

[0062] Specifically, the mounting holes 11 allow the permanent magnetic base plate to be conveniently mounted on the cycling shoe using bolts. Given the magnetic nature of the permanent magnetic base plate, the attraction of the permanent magnetic base plate to the bolts can affect the mounting bolts during the process. The use of the gasket 10 can provide a certain degree of isolation, reducing the difficulty of installation.

[0063] Example 6

[0064] Based on any one of the embodiments 1 to 5, Figure 1 、 Figure 4 and Figure 5 As shown, a limiting component is provided between the base 3 and the locking piece 1 .

[0065] By providing a limiting component, the locking plate 1 can be easily aligned with the base 3, thereby reducing the difficulty of using the locking pedal.

[0066] like Figure 1 、 Figure 4 and Figure 5 As shown, the limiting assembly includes at least two protrusions 31 provided on the base and at least two recesses 12 provided on the locking plate 1 , and each protrusion 31 corresponds to a recess 12 and is used to be embedded in the corresponding recess 12 .

[0067] Specifically, in the process of aligning the locking plate 1 and the base 3, the convex portion 31 is embedded into the concave portion 12 according to the feel of the foot. In addition, the concave portion 12 is provided on the locking plate 1 and will not affect the walking of the bicycle.

[0068] Among them, two protrusions 31 can be set, one at the front end and one at the rear end of the base 3. The shapes and sizes of the two protrusions 31 can be set differently, and the shape, position and size of the recess 12 correspond to the corresponding protrusion 31.

[0069] Based on the above-mentioned ideal embodiment of the present invention, and in accordance with the above description, relevant personnel can make various changes and modifications without departing from the technical scope of the present invention. The technical scope of the present invention is not limited to the content of the specification, but must be determined according to the scope of the claims.
