Description

Technical Field

[0001] The utility model relates to the technical field of electric power-assisted bicycle instruments, in particular to a centrally mounted instrument structure for an electric power-assisted bicycle. Background Art

[0002] The working principle of an electric-assisted bicycle is to provide power to the rider through an electric motor. The motor is usually mounted on the wheel or central axle, and is driven by electricity from a battery, thus providing power. When the rider pedals, the motor senses the rider's movement and automatically activates to provide power. The motor's output power can be adjusted by a controller, allowing the rider to select different power-assistance modes according to their needs.

[0003] The parameters and operating status of electric-assisted bicycles are displayed on their instruments, which are detachably connected to the handlebars via brackets. Current bracket structures, such as the utility model patent with authorization publication number CN 215513978 U, which discloses an angle adjustment structure, an adjustable instrument bracket, and an electric-assisted bicycle instrument, consist of a left bracket, a right bracket, and a rotating member. This structure, which consists of multiple separately connected components, is prone to loosening due to vibration and bumps during long periods of riding, as well as rotation around the handlebar connection. Therefore, there is an urgent need to provide a new mid-mounted instrument structure for electric-assisted bicycles. Utility Model Content

[0004] The technical problem to be solved by the utility model is: in order to overcome the disadvantages of the prior art that the instrument bracket is easy to loosen and rotate, the utility model provides a centrally mounted instrument structure for an electric power-assisted bicycle.

[0005] The technical solution adopted by the utility model to solve its technical problems is: a central instrument structure of an electric assisted bicycle, comprising a display screen, a bracket and a button assembly, wherein the button assembly is connected to the display screen through a line, a boss is provided on the back of the display screen, and a plurality of first connecting holes are provided on the boss, the bracket comprises a connecting plate, a support arm and a locking portion, the connecting plate is provided with a second connecting hole that matches the first connecting hole one by one, the two support arms are arranged side by side on the left and right sides of the connecting plate, and are integrally connected to the connecting plate, the end of the support arm away from the connecting plate is provided with a first arc-shaped groove, one end of the locking portion is hinged to the end of the support arm, and the other end of the locking portion is detachably connected to the middle part of the support arm through a detachable structure, and the locking portion is provided with a second arc-shaped groove opposite to the first arc-shaped groove on the side of the locking portion facing the first arc-shaped groove, and the first arc-shaped groove and the second arc-shaped groove together form a locking ring.

[0006] Furthermore, the support arm is arranged to be inclined with respect to the plane where the connecting plate is located, wherein a first inclination angle α of the support arm is 20°-45°, and a second inclination angle β is 30°-60°, and β ≥ α. The first inclination angle α is the angle between the outer edge of the support arm and the plane where the connecting plate is located, and the second inclination angle β is the angle between the inner edge of the support arm and the plane where the connecting plate is located.

[0007] Furthermore, to ensure the meter can be stably connected to the bicycle's mid-mounted structure, an anti-slip buffer is provided inside the locking ring and is a C-shaped ring structure. The anti-slip buffer has a certain elasticity and cushioning performance and is preferably made of TPU material.

[0008] Furthermore, to facilitate installation and removal, the anti-slip buffer has a first, inwardly concave relief groove on its outer wall and a second, outwardly concave relief groove on its inner wall, located directly opposite the hinged joint between the locking portion and the support arm. The relief grooves prevent interference when the locking portion rotates relative to the support arm about the hinged joint and reduce stress on the anti-slip buffer during rotation.

[0009] Preferably, there are three first connection holes and three second connection holes, which are distributed in a triangular pattern.

[0010] Specifically, the locking portion and the support arm are hinged via a pin.

[0011] Furthermore, a USB port is provided on the side of the boss.

[0012] Furthermore, the device also includes a sealing structure, comprising a USB port sealing structure and a display screen sealing structure. The USB port sealing structure is fully sealed with glue at the USB port, while the display screen sealing structure is sealed with glue at the connection between the screen and the upper and lower covers, as well as at the connection between the upper and lower covers. This glue-filling and glue-dispensing process ensures that the meter achieves a waterproof rating of X7, effectively ensuring water resistance.

[0013] Furthermore, the detachable structure includes a threaded hole arranged in the middle of the support arm, a through hole arranged on the other end of the locking part (the end away from the hinge), and a locking screw. The locking screw passes through the end of the through hole and is threadedly connected in the threaded hole to achieve locking between the support arm and the locking part, thereby fixing the instrument on the central structure of the bicycle.

[0014] The beneficial effects of the present invention are as follows: the present invention provides a centrally mounted instrument structure for an electric assisted bicycle, in which the connection part of the bracket and the display screen is integrated and detachably connected to the back of the display screen housing, thereby simplifying the structure of the bracket and avoiding loosening of the connection due to vibration and bumps; in addition, an anti-slip buffer is added to the locking ring of the bracket to prevent the instrument from rotating around the handlebar, thereby ensuring the stability of its position.
