Description

Technical Field

[0001] The invention relates to the field of electric bicycles, in particular to an electric bicycle motor that is easy to install. Background Art

[0002] An electric bicycle is a two-wheeled vehicle that uses a battery as an auxiliary energy source, is pedalable, and can be electrically assisted or driven. The motor is one of its core components, converting electrical energy into mechanical energy to propel the bicycle. Electric bicycle motors are categorized as either hub-driven or mid-mounted. The present invention relates to a hub-driven electric bicycle motor.

[0003] During the installation of electric bicycle motors, they are usually fixed directly with bolts. This fixing method requires manual alignment of multiple pairs of through holes and tightening of the bolts, which is inconvenient to use. In addition, since electric bicycles are bumpy during driving, the bolts may become loose, affecting the firmness of the motor after installation. Summary of the Invention

[0004] In view of the above-mentioned existing problems of inconvenience in installation by manually aligning multiple pairs of perforations and the easy falling off of bolts during driving, the present application is proposed.

[0005] Therefore, an object of the present invention is to provide an electric bicycle motor that is easy to install, which is to avoid the need for manual alignment of multiple pairs of through holes and reduce the possibility of bolts falling off.

[0006] The above technical problem is solved by the following technical solution: The present invention proposes an easy-to-install electric bicycle motor, which includes:

[0007] a motor element, the motor element comprising a tire and a motor body, and a supporting portion disposed on the tire;

[0008] A fastening element, the fastening element comprising a fastening portion provided on the motor body, four limiting portions provided on the fastening portion, and two positioning portions provided on the fastening portion;

[0009] A fixing element, the fixing element comprising a plug-in portion provided on the supporting portion and four fixing portions provided on the supporting portion;

[0010] The positioning portion cooperates with the plug-in portion to determine the installation position; the fastening portion cooperates with the plug-in portion to install the motor body; and the limiting portion cooperates with the fixing portion to limit the motor body.

[0011] In a preferred embodiment of the easy-to-install electric bicycle motor of the present invention, the supporting portion includes a mounting plate detachably disposed in the tire and a mounting groove disposed in the mounting plate.

[0012] In a preferred embodiment of the easy-to-install electric bicycle motor of the present invention, the fastening portion includes a mounting ring fixedly arranged on the motor body, and four first screws penetrating the mounting ring and threadedly connected to the mounting ring.

[0013] In a preferred embodiment of the easy-to-install electric bicycle motor of the present invention, the limiting portion includes a second screw rod fixedly arranged at one end of the first screw rod, and a sleeve threadedly arranged on the second screw rod.

[0014] In a preferred embodiment of the easy-to-install electric bicycle motor of the present invention: the limiting part also includes limiting rods rotatably arranged on the upper and lower walls of the sleeve, and the limiting rods are connected to the sleeve through torsion springs, and the limiting rods rotate toward the direction of the first screw.

[0015] In a preferred embodiment of the easy-to-install electric bicycle motor of the present invention, the positioning portion includes a positioning block provided on one side of the mounting ring, and the positioning block is provided toward the second screw rod.

[0016] In a preferred embodiment of the easy-to-install electric bicycle motor of the present invention, the positioning portion further includes a telescopic rod with both ends fixedly disposed on the positioning block and the mounting ring, and the positioning block and the mounting ring are elastically connected via a spring.

[0017] In a preferred embodiment of the easy-to-install electric bicycle motor of the present invention: the plug-in part includes four threaded grooves penetrating the side wall of the mounting plate and two positioning grooves penetrating the side wall of the mounting plate. The torsion spring is compressed and the limiting rod passes through the threaded groove smoothly.

[0018] In a preferred embodiment of the easy-to-install electric bicycle motor of the present invention: the first screw is threadedly connected to the thread groove, the positioning block is matched with the positioning groove, and the longitudinal cross-sectional area of the positioning block is larger than the longitudinal cross-sectional area of the thread groove.

[0019] In a preferred embodiment of the easy-to-install electric bicycle motor of the present invention: the fixing part includes four rotating seats rotatably set on the rear wall of the mounting plate, a connecting rod fixedly set on the rotating seat, and a threaded tube fixedly set on the connecting rod; when the torsion spring is compressed, the limiting rod passes through the threaded tube smoothly; when the torsion spring is stretched, the limiting rod cannot pass through the threaded tube.

[0020] The beneficial effects of the present invention are as follows: when the motor body is inserted through the mounting slot, the mounting ring abuts against the mounting plate, the spring and the telescopic rod are compressed, and the motor body is rotated. When the positioning block rotates to the positioning slot, the spring and the telescopic rod extend, and the positioning block enters the positioning slot. At this time, the four first screws are aligned with the four thread grooves.

[0021] By rotating the first screw, when the limit rod hits the thread groove, the thread groove forces it to rotate in the direction of the first screw, and the first screw is smoothly screwed into the thread groove. The connecting rod is rotated, and the position allows the first screw to be smoothly screwed into the threaded tube. When the first screw is rotated out of the threaded tube, the limit rod pops out, and the sleeve is rotated to make the limit rod close to the threaded tube, completing the installation of the motor. Compared with the traditional method, this device can quickly install the motor without the need for manual hole alignment, and the setting of the limit rod effectively avoids the possibility of the first screw being rotated out of the threaded tube, thereby ensuring riding safety.

[0035] Reference Figure 1 This embodiment provides an easy-to-install electric bicycle motor, including

[0036] The motor element 1 includes a tire 11 and a motor body 13. The tire 11 is provided with a support portion 12. The support portion 12 includes a mounting plate 121 that is detachably disposed within the tire 11 and a mounting slot 122 that extends through the mounting plate 121. The mounting plate 121 is used for installing and removing the tire 11, and the mounting slot 122 is used for mounting the motor body 13.

[0037] The fastening element 2 includes a fastening portion 21 provided on the motor body 13 . The fastening portion 21 includes a mounting ring 211 fixedly provided on the motor body 13 , and four first screws 212 penetrating the mounting ring 211 and threadedly connected thereto.

[0038] The fastening portion 21 is provided with four limiting portions 22. The limiting portions 22 include a second screw 221 fixedly mounted at one end of the first screw 212, and a sleeve 222 threadedly mounted on the second screw 221. The second screw 221 is positioned adjacent to the mounting plate 121, and the sleeve 222 is used to adjust the fastening position. The diameter of the second screw 221 is smaller than that of the first screw 212.

[0039] The limiting portion 22 also includes limiting rods 223 rotatably mounted on the upper and lower walls of the sleeve 222. Each limiting rod 223 is connected to the sleeve 222 via a torsion spring 224. The limiting rods 223 rotate toward the first screw 212. The torsion spring 224, a commercially available mechanical element that uses elastic deformation to store and release energy, has a core function of providing a reset or limiting effect through torsional force. The torsion spring 224 can only rotate toward the first screw 212 and is limited when the angle between the torsion spring 224 and the first screw 212 exceeds 90 degrees.

[0040] The fastening portion 21 is provided with a positioning portion 23, which includes a positioning block 231 disposed on one side of the mounting ring 211, and is positioned toward the second screw 221. The positioning portion 23 also includes a telescopic rod 232 with its ends fixedly attached to the positioning block 231 and the mounting ring 211. The positioning block 231 and the mounting ring 211 are elastically connected by a spring 233.

[0041] A fixing element 3 is provided on the side wall of the mounting plate 121. The fixing element 3 includes a plug-in portion 31 provided on the supporting portion 12. The plug-in portion 31 includes four thread grooves 311 provided through the side wall of the mounting plate 121 and two positioning grooves 312 provided through the side wall of the mounting plate 121. When the torsion spring 224 is compressed, the limiting rod 223 passes through the thread groove 311 smoothly and will not interfere with the screwing of the first screw rod 212 and the thread groove 311.

[0042] The first screw rod 212 is threadedly connected to the thread groove 311. The positioning block 231 is arranged in cooperation with the positioning groove 312, and the longitudinal cross-sectional area of the positioning block 231 is larger than the longitudinal cross-sectional area of the thread groove 311. The positioning block 231 can smoothly enter the positioning groove 312, thereby quickly positioning the first screw rod 212. During this process, the positioning block 231 will not enter the thread groove 311, resulting in positioning errors.

[0043] Four fixing parts 32 are provided on the supporting part 12, and the fixing part 32 includes four rotating seats 321 rotatably set on the rear wall of the mounting plate 121, a connecting rod 322 fixedly set on the rotating seat 321, and a threaded tube 323 fixedly set on the connecting rod 322. The torsion spring 224 is compressed, and the limiting rod 223 passes through the threaded tube 323 smoothly. The torsion spring 224 is stretched, and the limiting rod 223 cannot pass through the threaded tube 323, thereby ensuring that the first screw rod 212 can pass through the threaded tube 323 smoothly, and the limiting rod 223 plays a limiting role on the threaded tube 323. Among them, since the first screw rod 212 cannot be separated from the mounting ring 211, it is possible to screw the first screw rod 212 with the thread groove 311 and the threaded tube 323 when it rotates.

[0044] In one embodiment provided herein, the motor body 13 is first inserted through the mounting slot 122 . At this time, the mounting ring 211 abuts against the mounting plate 121 , and the spring 233 and the telescopic rod 232 are compressed. The motor body 13 is rotated. When the positioning block 231 rotates to the positioning slot 312 , the spring 233 and the telescopic rod 232 extend, and the positioning block 231 enters the positioning slot 312 . At this time, the four first screws 212 are aligned with the four threaded grooves 311 .

[0045] By rotating the first screw rod 212, when the limiting rod 223 contacts the threaded groove 311, the threaded groove 311 forces it to rotate in the direction of the first screw rod 212, and the first screw rod 212 is smoothly screwed into the threaded groove 311. The connecting rod 322 is rotated, and the position of the first screw 212 is smoothly screwed into the threaded tube 323. When the first screw 212 is rotated out of the threaded tube 323, the limiting rod 223 pops out, and the sleeve 222 is rotated so that the limiting rod 223 is close to the threaded tube 323, completing the installation of the motor body 13. The device can quickly install the motor body 13 without the need for manual hole alignment, and the setting of the limiting rod 223 effectively avoids the possibility of the first screw 212 being rotated out of the threaded tube 323, thereby ensuring riding safety.
