Technical Field

[0001] The utility model relates to the technical field of electric power-assisted bicycles, in particular to an electric power-assisted bicycle controller. Background Art

[0002] An electric power-assisted bicycle is a mechatronic vehicle that uses batteries as auxiliary energy and is based on an ordinary small car and is equipped with motors, controllers, batteries, throttles, brake handles and other operating components and display instrument systems. The battery must be charged before use. At present, when an electric power-assisted bicycle is assembled and used, a DC controller is usually installed on the body of the electric power-assisted bicycle to control the start, operation, advance and retreat, speed, stop of the electric vehicle motor and the core control components of other electronic components of the electric vehicle.

[0003] At present, when the DC controller of an electric power-assisted bicycle is installed on the electric vehicle, the plates at both ends of the DC controller are usually locked on the frame of the electric vehicle with bolts. When the electric vehicle is running, the DC controller installed in direct contact with the frame of the electric vehicle is prone to bumps, which may cause desoldering of the internal components of the DC controller or bump damage to the internal components of the DC controller, thereby affecting the service life of the DC controller. To this end, we propose an electric power-assisted bicycle controller. Utility Model Content

[0004] The main purpose of the utility model is to provide an electric power-assisted bicycle controller, in which a buffer mechanism is improved and configured at the side mounting plate of the DC controller. The DC controller can be installed on the frame of the electric power-assisted bicycle with the help of the buffer mechanism. When the electric power-assisted bicycle generates vibration during driving, a guiding vibration reduction structure is provided between the DC controller and the frame of the electric power-assisted bicycle, which can effectively realize vibration reduction protection of the DC controller after being installed on the electric power-assisted bicycle, effectively avoid the DC controller from being damaged by vibration during driving of the electric power-assisted bicycle, and can effectively solve the problems in the background technology.

[0005] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0006] A controller for an electric power-assisted vehicle comprises a DC controller and a side-mounted plate, wherein the side-mounted plates are installed at both ends of a box body of the DC controller, and the surface of the side-mounted plates is provided with surface-mounted holes. The controller also comprises a buffer mechanism, wherein the buffer mechanism comprises a guide hole, a conduit, a substrate, a bottom-mounted hole, a bare rod bolt, a vibration-damping pad, an embedding hole and a plastic spring. The side-mounted plates between the surface-mounted holes are provided with guide holes, and conduits are inserted into the guide holes. The conduits are symmetrically welded to the surface of the substrate, and the substrate below the surface-mounted holes is provided with bottom-mounted holes, and a bare rod bolt is inserted between the surface-mounted hole and the bottom-mounted hole. A vibration-damping pad contacting the bottom surface of a DC controller housing is bonded to the surface of the substrate between the conduits, and an embedding hole for embedding a plastic spring is provided on the pad body of the vibration-damping pad.

[0007] Furthermore, the hole diameter of the embedded hole is the same as the spring coil diameter of the plastic spring;

[0008] By adopting the above technical solution, the hole body of the embedded hole can accommodate the plastic spring, and as the vibration-damping pad is deformed, the plastic spring can be compressed and elastic.

[0009] Furthermore, a rubber ring is sleeved outside the tube body of the catheter, and the rubber ring is pressed on the surface of the substrate;

[0010] By adopting the above technical solution, when the conduit guides the DC controller and the side mounting plate to press against the base plate, the rubber ring bears the downward pressure of the side mounting plate to perform elastic buffering.

[0011] Furthermore, the unthreaded rod of the polished rod bolt is inserted into the surface mounting hole and the bottom mounting hole, and the bottom of the polished rod bolt has a threaded rod passing through the bottom hole opening of the bottom mounting hole;

[0012] By adopting the above technical solution, the threadless rod body of the polished rod bolt allows the side mounting plate to slide and press toward the base plate at the threadless rod body through the surface mounting hole.

[0013] Furthermore, the diameter of the tube body of the conduit is the same as the diameter of the orifice of the guide hole, and the height of the tube body of the conduit is greater than the thickness of the pad body of the vibration damping pad;

[0014] By adopting the above technical solution, the conduit can be adapted and inserted into the guide hole for adaptation and engagement, and the conduit guides the edge mounting plate to be pressed toward the base plate at the guide hole.

[0015] Further, three groups of vibration-damping pads are bonded to the surface of the substrate;

[0016] By adopting the above technical solution, the substrate provides vibration-damping support for the DC controller with more vibration-damping pads.

[0017] Compared with the prior art, the utility model has the following beneficial effects:

[0018] The utility model improves the configuration of a buffer mechanism at the side mounting plate of the DC controller, and the DC controller can be installed on the frame of the electric power-assisted vehicle with the help of the buffer mechanism. When vibration is generated during the driving of the electric power-assisted vehicle, a guiding vibration reduction structure is provided between the DC controller and the frame of the electric power-assisted vehicle, which can effectively implement vibration reduction protection after the DC controller is installed on the electric power-assisted vehicle, and effectively prevent the DC controller from being damaged by vibration during the driving of the electric power-assisted vehicle.

[0022] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0023] like Figure 1-2 As shown, an electric power-assisted vehicle controller comprises a DC controller 1 and a side-mounted plate 2, the side-mounted plates 2 are installed at both ends of the box body of the DC controller 1, and the surface of the side-mounted plate 2 is provided with surface-mounted holes 3, and also comprises a buffer mechanism 4, the buffer mechanism 4 comprises a guide hole 5, a conduit 6, a base plate 7, a bottom-mounted hole 8, a bare rod bolt 9, a vibration-damping pad 10, an embedding hole 11 and a plastic spring 12, the side-mounted plate 2 between the surface-mounted holes 3 is provided with a guide hole 5, and the conduit 6 is inserted into the guide hole 5, the conduit 6 is symmetrically welded to the plate surface of the base plate 7, the base plate 7 below the surface-mounted hole 3 is provided with a bottom-mounted hole 8, and a bare rod bolt 9 is inserted between the surface-mounted hole 3 and the bottom-mounted hole 8, the surface of the base plate 7 between the conduits 6 is bonded with a vibration-damping pad 10 contacting the bottom surface of the DC controller 1 shell, and the pad body of the vibration-damping pad 10 is provided with an embedding hole 11 for embedding the plastic spring 12.

[0024] The hole diameter of the embedding hole 11 is the same as the spring coil diameter of the plastic spring 12;

[0025] By adopting the above technical solution, the hole body of the embedding hole 11 can accommodate the plastic spring 12, and as the vibration-damping pad 10 is deformed, the plastic spring 12 can be compressed and elastic.

[0026] Wherein, a rubber ring 13 is inserted into the outer sleeve of the tube body of the catheter 6, and the rubber ring 13 is pressed on the surface of the substrate 7;

[0027] By adopting the above technical solution, when the conduit 6 guides the DC controller 1 and the side mounting plate 2 to press against the base plate 7, the rubber ring 13 bears the downward pressure of the side mounting plate 2 to perform elastic buffering.

[0028] The unthreaded rod of the polished bolt 9 is inserted into the surface mounting hole 3 and the bottom mounting hole 8, and the bottom of the polished bolt 9 has a threaded rod passing through the bottom hole of the bottom mounting hole 8;

[0029] By adopting the above technical solution, the unthreaded rod body of the polished rod bolt 9 enables the side mounting plate 2 to slide and press toward the base plate 7 at the unthreaded rod body through the surface mounting hole 3 .

[0030] The diameter of the tube body of the conduit 6 is the same as the diameter of the opening of the guide hole 5, and the height of the tube body of the conduit 6 is greater than the thickness of the cushion body of the vibration damping cushion 10;

[0031] By adopting the above technical solution, the conduit 6 can be adapted and inserted into the guide hole 5 for adaptation and engagement, and the conduit 6 guides the edge mounting plate 2 to be pressed toward the base plate 7 at the guide hole 5 .

[0032] Among them, there are three groups of vibration damping pads 10 bonded on the surface of the substrate 7;

[0033] By adopting the above technical solution, the base plate 7 provides vibration-damping support for the DC controller 1 with a large number of vibration-damping pads 10 .

[0034] It should be noted that the utility model is an electric power-assisted vehicle controller, in which a buffer mechanism 4 is improved and configured at the side mounting plate 2 of the DC controller 1. When the DC controller 1 needs to be installed at the frame of the electric power-assisted vehicle, the base plate 7 of the buffer mechanism 4 contacts the housing of the DC controller 1 with the vibration-damping pad 10, and then the conduit 6 on the surface of the base plate 7 is inserted into the guide hole 5 of the side mounting plate 2. At this time, the bare rod bolt 9 passes through the bottom mounting hole 8 of the base plate 7 from the surface mounting hole 3 to the mounting hole of the electric power-assisted vehicle frame. When the electric power-assisted vehicle generates bumps and vibrations during driving, the vibration force is transmitted to the base plate 7. The vibration force of the substrate 7 is transmitted to the DC controller 1 after being buffered by the elastic deformation of the vibration-damping pad 10. A plastic spring 12 is arranged in the embedding hole 11 of the vibration-damping pad 10 to increase its elastic offsetting force when deformed. When the vibration force of the bare rod bolt 9 is transmitted to the side mounting plate 2 of the DC controller 1 to cause vibration, the DC controller 1 is pressed toward the substrate 7 under the action of the force, and the vibration-damping pad 10 is used to buffer the substrate 7 and the DC controller 1 again, thereby realizing the vibration reduction protection of the DC controller 1 after being installed at the electric power-assisted vehicle, and preventing the DC controller 1 from being damaged by the vibration during the driving of the electric power-assisted vehicle.
