Detailed Implementation

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] Example 1:

[0030] Please see Figures 1-5 A drive connection structure for an electric motor includes a bicycle frame 1, with a front wheel 4 mounted on the inner wall of the bicycle frame 1 via a drive assembly 5.

[0031] The drive assembly 5 includes a front protective cover 510 and a rear protective cover 51. The outer walls of the front protective cover 510 and the rear protective cover 51 are both fixed to the outer wall of the bicycle frame 1 by a number of screws 52. A connecting shaft 54 ​​is rotatably mounted on the bottom of the inner wall of the bicycle frame 1 through a transmission bearing seat 55. The front end of the connecting shaft 54 ​​passes through the bicycle frame 1 through a bearing and is fixedly mounted on a first transmission sprocket 56. A servo motor 59 is fixedly mounted on the top of the front wall of the front protective cover 510. The power shaft of the servo motor 59 passes through the front protective cover 510 through a bearing and is fixedly mounted on a second transmission sprocket 58. The outer walls of the second transmission sprocket 58 and the first transmission sprocket 56 are both driven by the same transmission chain 57.

[0032] In this embodiment of the utility model, the purpose of this setting is that the drive component 5 can provide good auxiliary drive for the entire bicycle when the rider encounters an uphill or is physically exhausted, while not affecting the rider's normal manual drive of the rear wheel rotation. By combining electric and manual methods, the rider can ride more effortlessly and conveniently.

[0033] Example 2:

[0034] Please see Figures 1-5 This embodiment provides a technical solution based on embodiment one: the front protective cover 510 and the rear protective cover 51 are arranged symmetrically front and rear. The battery pack 53 is fixedly installed on the inner wall of the rear protective cover 51. The outer wall of the connecting shaft 54 ​​is fixedly connected to the center of the inner wall of the front wheel 4. The second transmission sprocket 58, the first transmission sprocket 56 and the transmission chain 57 are all located inside the front protective cover 510. The battery pack 53 is electrically connected to the servo motor 59. The front wall of the front protective cover 510 and the position corresponding to the servo motor 59 are fixedly installed with protective frames 511. The four corners of the front wall of the protective frame 511 are screwed with dustproof nets 512 by fastening bolts 513. The handlebars 2 are fixedly installed on the front and rear walls of the top of the bicycle frame 1. The microcontroller 3 is fixedly installed at the center of the top wall of the bicycle frame 1. The mudguard 6 is fixedly installed on the left side of the outer wall of the bicycle frame 1.

[0035] In this embodiment of the utility model, the purpose of this arrangement is that the front protective cover 510 and the rear protective cover 51 are arranged symmetrically front and rear, and the battery pack 53 is fixedly installed on the inner wall of the rear protective cover 51. This can prevent the position of the bicycle frame 1 from shifting, so that the center of gravity of the front wheel 4 is always kept at the center of gravity, which is beneficial to riding safety. The microcontroller 3 can control the start and stop of the servo motor 59, and can also adjust the rotation speed of the servo motor 59 to adjust to a suitable auxiliary driving force under various conditions. The protective frame 511 has a protective function for the servo motor 59. When working for a long time, the heat generated by the servo motor 59 can be dissipated through the dustproof net 512, and it can also prevent external dust and impurities from entering the interior of the protective frame 511.

[0036] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0037] During operation, the servo motor 59 is first electrically connected to the microcontroller 3 and battery pack 53. When the rider encounters exhaustion or uphill sections and needs to use the drive assembly 5 for auxiliary drive, the microcontroller 3 controls the servo motor 59 to start working. The power shaft of the servo motor 59 drives the transmission sprocket 2 58 to rotate. When the transmission sprocket 2 58 rotates, it drives the transmission sprocket 1 56 to rotate through the transmission chain 57. The transmission sprocket 1 56 synchronously drives the connecting shaft 54 ​​and the front wheel 4 to rotate. The front wheel 4 rotates in the inner wall of the bicycle frame 1. The microcontroller 3 can control the rotation speed of the servo motor 59, making it easier for the rider to ride. The servo motor 59 installed inside the protective frame 511 generates heat during operation, which can be dissipated from the dustproof net 512 to prevent overheating and damage to the servo motor 59.
