Description

Technical Field

[0001] The present invention relates to the technical field of controller structure design, and in particular to a modular integrated socket controller. Background Art

[0002] The electric vehicle controller is a core control device used to control the start, operation, advance and retreat, speed, stop of the electric vehicle motor and other electronic components of the electric vehicle. It is like the brain of the electric vehicle and is an important component of the electric vehicle.

[0003] At present, the functional requirements of power-assisted bicycle controllers are increasing, which leads to an increase in the wiring harness at the controller connection end.

[0051] The present invention will be described in detail below with reference to specific embodiments. The following examples will help those skilled in the art to further understand the present invention, but are not intended to limit the present invention in any form. It should be noted that, for those skilled in the art, several changes and improvements can be made without departing from the scope of the present invention. These all fall within the scope of protection of the present invention.

[0052] Example 1

[0053] like Figures 1 to 4 As shown, a modular integrated socket 1 controller provided according to the present invention includes an integrated socket 1 assembly, a main shell 2, a circuit board assembly 3 and a cover plate 6. The integrated socket 1 assembly is arranged at one end of the main shell 2, the cover plate 6 is arranged at the other end of the main shell 2, and the circuit board assembly 3 is arranged in a space surrounded by the integrated socket 1 assembly, the main shell 2 and the cover plate 6. The integrated socket 1 assembly includes a fixed module 101 and a replacement module 102. The fixed module 101 is integrated with a plug-in for the basic necessary functions of the controller. The replacement module 102 is integrated with a plug-in for optional functions, or no plug-in is integrated. Any integrated socket 1 assembly formed by the detachable cooperation of the fixed module 101 and one or more replacement modules 102 can be assembled to the corresponding position of the main shell 2.

[0054] The integrated socket 1 assembly consisting of the fixed module 101 and the replacement module 102 can be detachably installed in the corresponding position of the main shell 2. When the controller is manufactured, the whole composed of the main shell 2, the circuit board assembly 3 and the cover plate 6 can be separately processed and assembled with the integrated socket 1 assembly. According to different functional requirements, the integrated socket 1 assembly composed of different replacement modules 102 can be selected, which can realize mass production and is easy to disassemble and assemble.

[0055] Specifically, the shape of the main shell 2 can be a hollow rectangle, and the material of the main shell 2 can be plastic, and it can be waterproof and prevent electric shock. The circuit board is fixedly mounted on the rib plate inside the main shell 2 or on the side wall of the main shell 2 by screws and other fasteners in the prior art. The cover plate 6 can be made of plastic, and the peripheral edge of the cover plate 6 is provided with connection holes. The cover plate 6 is assembled and connected to the main shell 2 through the cooperation of fasteners and connection holes, and a sealing gasket 5 is also provided between the cover plate 6 and the main shell 2. The peripheral edge of the fixed module 101 and / or the replacement module 102 is provided with connection holes. The integrated socket 1 assembly formed by the fixed module 101 and one or more replacement modules 102 is assembled and connected to the main shell 2 through the cooperation of fasteners and connection holes. The fasteners of this embodiment preferably use the fixing screws 7 in the prior art.

[0056] Specifically, the basic essential functions integrated into fixed module 101 include: positive and negative power plugs 12, which connect to the power source to power the device; waterproof cable connector 13, which connects to the motor output; and plug-in plastic housing 14, which connects to the instrument output. Optional functions integrated into replacement module 102 include one or more of: communication, torque, throttle, gear shifting, speed measurement, Hall effect, front and rear lights, left and right turn signals, and one-touch start. The plug-in for these optional functions is plug-in plastic housing 14.

[0057] Furthermore, the fixed module 101 is connected to the adjacent replacement module 102 via a detachable structure, and the replacement module 102 is connected to the adjacent fixed module 101 and / or replacement module 102 via a detachable structure. The detachable structure includes a buckle, a snap ring, or a detachable connector. Preferably, the side surface where the fixed module 101 is connected to the replacement module 102 is a plane, and the side surface where the replacement module 102 is connected to the fixed module 101 and / or replacement module 102 is a plane. The side surface of the fixed module 101 can be aligned with the side surface of the replacement module 102, and the side surface of the replacement module 102 can be aligned with the side surface of the fixed module 101 or the side surface of another replacement module 102.

[0058] Furthermore, the integrated socket assembly 1 is electrically connected to the circuit board. Both the fixed module 101 and the replacement module 102 include a base 11, with a plug-in plastic shell 14 integrated thereon. Pin holes are reserved on the base 11 within the plug-in plastic shell 14. A connecting plate 4 is fixedly mounted within the main housing 2. This plate is equipped with metal contacts corresponding to the ferrules and is electrically connected to the circuit board assembly 3.

[0059] The pin holes are equipped with a pin assembly 15 , which includes a pin header and / or a spring pin 17 .

[0060] In a feasible implementation manner, the pin header includes a straight pin header and / or a positive and negative bend pin header.

[0061] In another feasible embodiment, one end of the spring core of the spring pin 17 extends from the interior of the main housing 2 through the base 11 and into the mating plastic shell 14 , and the other end of the spring core contacts the metal contact on the connecting plate 4 .

[0062] It should be noted that the plug housing 14 can be built with pin assemblies 15 of different numbers of cores. The current range of the number of cores is 2 to 8 to cope with different functions.

[0063] During installation, a plurality of pin holes are reserved on the base 11, and the pin assembly 15 on the plastic shell 14 can be inserted into the corresponding holes and connected to the base 11. Then glue is poured into the sealing groove of the base 11 to seal and waterproof. The metal pins can be directly welded to the circuit board assembly 3, or connected to it through electronic wires to achieve signal docking. Preferably, ordinary metal pins can be replaced with spring pins 17. The docking connection plate 4 is pre-fixed in the shell 2, and corresponding metal contacts are reserved thereon. When installing the integrated socket 1, the welding step can be omitted, and the spring pin itself can be pressed on the contact of the connection plate 4 to achieve signal connection.

[0064] The fixed module 101 also includes a wire storage box 18, which includes a space for storing the waterproof wire. A through hole is reserved on the base 11 of the fixed module 101 to allow the waterproof wire to pass through. The waterproof wire connector 13 is located on the side of the base 11 of the fixed module 101 away from the wire storage box 18.

[0065] On the basis of this embodiment, those skilled in the art may further design the storage of the waterproof line to improve the storage effect of the waterproof line.

[0066] Example 2

[0067] like Figures 1 to 6 As shown, based on Example 1, a wiring harness retracting structure for a controller provided according to the present invention includes an integrated socket 1 component, a main shell 2, a circuit board component 3, a cover plate 6 and a connector wiring harness. The integrated socket 1 component is arranged at one end of the main shell 2, the cover plate 6 is arranged at the other end of the main shell 2, and the circuit board component 3 is arranged in a space surrounded by the integrated socket 1 component, the main shell 2 and the cover plate 6.

[0068] The integrated socket 1 assembly includes a base 11 and a wire storage box 18. The wire storage box 18 includes space for storing the connector wiring harness. A through hole is reserved on the base 11 to allow the connector wiring harness to pass through. One end of the connector wiring harness is connected to the circuit board assembly 3, and the other end of the connector wiring harness extends from the inside to the outside after passing through the through holes on the wire storage box 18 and the base 11. A connector connected to the motor output line is formed at the end of the connector wiring harness extending out of the base 11.

[0069] In actual use, the connector harness needs to be pulled out from the wire storage box 18 during installation. The length of the connector harness pulled out is determined according to actual conditions. If the connector harness is pulled out too long, it will cause inconvenience in wiring, and if the connector harness is pulled out too short, it will not be able to connect to the motor output line. In this embodiment, the wire storage box 18 is used to store the connector harness. During installation, the connector harness can be pulled out to a specific length as needed.

[0070] In one embodiment: the connector wiring harness includes a spiral section, the spiral section of the connector wiring harness is arranged in the wire storage box 18, and the spiral section of the connector wiring harness is elastic. The connector wiring harness includes a waterproof wire, and the material of the connector wiring harness sheath is a flexible material. The connector wiring harness is stored in the wire storage box 18 in a spiral form, and its length meets the basic usage scenarios. And because the spiral section of the connector wiring harness is elastic, if the pulled-out connector wiring harness is too long, the connector wiring harness can be retracted into the wire storage box 18 under the elastic action of the spiral section, thereby ensuring that the length of the connector wiring harness is moderate. The sheath of the waterproof wire uses a flexible material, and during the wiring harness manufacturing process, it is injection molded in the form of a spiral wire. The spiral sections of the wiring harness can be placed in order in the wire storage box 18, and the electronic wires at the tail end are connected to the circuit board.

[0071] When the waterproof cable connector is docked with the motor cable, if the controller installation position exceeds the original distance or the docking position is not convenient for installation, the waterproof cable can be pulled outward to facilitate the connection between the controller and the motor. After installation, the wiring harness can be released and it will naturally retract along the spiral path. The retracted wiring harness is stored in the wire storage box 18 without interfering with the circuit board assembly 3 in the housing 2 and damaging the controller function.

[0072] In another embodiment, a winding drum 20 is rotatably provided in the wire storage box 18, and the connector wire harness is wound on the winding drum 20. The connector wire harness located in the innermost circle is fixedly connected to the winding drum 20. The winding drum 20 is also provided with a one-way tension locking device. When the connector wire harness is pulled, the winding drum 20 rotates and unwinds, and the connector wire harness is pulled out. A fixing column 181 is provided on the inner wall of the wire storage box 18, and the winding drum 20 is rotatably mounted on the fixing column 181.

[0073] Furthermore, the one-way tension locking device includes a ratchet 21, a pawl 23, and a spring stopper 24. The ratchet 21 is fixedly connected to the winding reel 20, the pawl 23 is rotatably arranged in the wire storage box 18, the pawl 23 is engaged with the ratchet 21, and the spring stopper 24 is arranged below the pawl 23, and the spring stopper 24 is in contact with the pawl 23. A rotating shaft is provided on the pawl 23, and the rotating shaft is rotatably mounted on the side wall of the wire storage box 18. One end of the rotating shaft passes through the wire storage box 18 from the inside to the outside, and a paddle is fixedly provided on the end of the rotating shaft extending from the wire storage box 18. The spring stopper 24 includes a return spring and a stopper 24. A slot is provided on the pawl 23, and a pressing plate is provided on the outside of the wire storage box 18, which is fixedly connected to the stopper 24.

[0074] In the first state, the limiting block 24 is embedded in the slot, and the pawl 23 is separated from the ratchet 21 .

[0075] In the second state, the limiting block 24 is separated from the slot, the lower surface of the pawl 23 contacts the upper surface of the limiting block 24 , and the pawl 23 is engaged with the ratchet 21 .

[0076] Through the one-way limiting effect of the ratchet 21 and the pawl 23, when releasing the wire, the user pulls the connector harness outward, and the ratchet 21 and the pawl 23 cooperate to control the one-way rotation of the winding drum 20 and can lock the position of the winding drum 20.

[0077] Furthermore, a coil spring 22 is provided in the wire storage box 18. The inner end of the coil spring 22 is fixedly connected to the fixing post 181, and the outer end of the coil spring 22 is fixedly connected to the winding reel 20. When the winding reel 20 rotates to unwind, the coil spring 22 stores elastic potential energy. When it is necessary to rewind, the staff releases the pawl 23 and the ratchet 21 from limiting the winding reel 20 by using the paddle and the pressing plate. The elastic potential energy of the coil spring 22 is released, driving the winding reel 20 to rotate and rewind.

[0078] In one feasible embodiment, the sidewalls of the wire storage box 18 are provided with vertical and horizontal waist-shaped grooves. The paddle can move along the horizontal waist-shaped groove, and the pressing plate can move along the vertical waist-shaped groove. To unlock, the operator operates the pressing plate downward along the vertical waist-shaped groove and operates the paddle along the horizontal waist-shaped groove away from the ratchet 21 until the stop block 24 engages the slot. At this point, the pawl 23 disengages from the ratchet 21, and the one-way tension locking device releases the lock on the wire reel 20.

[0079] During the stretching process of the wiring harness, the ratchet 21 is driven to rotate, and the ratchet 23 cooperates to form an intermittent unidirectional motion mechanism. Every time a small section of the wiring harness is pulled out, the ratchet 21 rotates one grid, and the number of teeth is relatively large. During stretching, the ratchet 21 rotates almost steplessly and evenly, and the stretching speed changes relatively smoothly and controllably without significant fluctuations. Each time the ratchet 23 is turned, it will be stuck between the two teeth of the ratchet 21, forming a self-locking function. The wiring harness can only be pulled out in one direction and cannot be reversed. If it is turned inward, the wiring harness will not automatically retract into the wiring storage box 18. When the wiring harness is stretched too long and needs to be retracted, the ratchet 23 is turned backward. During the movement, due to the spring under the limit block 24 that can be compressed, the slot of the ratchet 23 is eventually stuck above the limit block 24, causing the ratchet 21 and the ratchet 23 to separate, and the lock of the wiring harness is released. The inner end of the coil spring 22 is connected to the fixed column 181, and the outer end is connected to the winding reel 20. In the unlocked state, the wire harness is pushed inward, and the slight elastic force of the winding spring 22 can drive the winding drum 20 to rotate, so that the wire harness is automatically and smoothly retracted. Pressing the limit block 24 downward again and sliding the pawl 23 back to its original position, cooperating with the ratchet 21, can restore the self-locking function.

[0080] In a preferred embodiment, the upper surface of the limit block 24 is a spherical surface, the engaging groove is a semicircular groove, and the lower surface of the pawl 23 in contact with the limit block 24 is an inclined plane.

[0081] The integrated socket 1 assembly is provided with connection holes along its circumferential edges, and is assembled and connected to the main housing 2 through the cooperation of fasteners and connection holes. The cover plate 6 is also provided with connection holes along its circumferential edges, and is assembled and connected to the main housing 2 through the cooperation of fasteners and connection holes. A sealing gasket 5 is also provided between the cover plate 6 and the main housing 2.
