Description

Technical Field

[0001] This invention relates to the field of controller structure design technology, and more specifically, to a modular integrated socket controller. Background Technology

[0002] The electric vehicle controller is a core control device used to control the starting, running, forward and backward movement, speed, and stopping of the electric vehicle motor, as well as other electronic components of the electric vehicle. It is like the brain of the electric vehicle and is an important component.

[0003] Currently, the functional requirements of electric bicycle controllers are increasing, which leads to an increase in the wiring harness at the controller connection point.

[0004] Chinese patent application CN209563016U discloses an electric vehicle controller housing structure, specifically a die-cast electric vehicle controller housing structure with integrated plugs, belonging to the field of electric vehicle controller technology. It includes a base, a panel, and a cover plate. The panel is detachably connected to the base via multiple connectors. An inner ring of the base has a mounting plate for positioning and mounting the core plate. The panel covers the core plate. The panel has a terminal block seat with multiple terminal hole holes. The cover plate is fastened to the terminal block seat, covering the multiple terminal hole holes. Each terminal hole contains an integrated terminal block.

[0005] In existing technologies, the plug structure of controllers is a fixed, integrated structure. As the functional requirements of electric bicycle controllers increase, the wiring harness at the controller connection point also needs to be increased. To meet the diverse needs of users and accommodate all operating conditions with all functions, material costs would be high. Conversely, if all functions are not pre-configured, different wiring harnesses would be needed to meet different requirements, leading to difficulties in material management. From a controller manufacturing perspective, producing controllers with different plug structures to meet different needs can easily lead to material stockpiling, and small-batch production is not conducive to industrial-scale production, indicating areas for improvement.

[0008] The integrated socket assembly includes a fixed module and a replacement module, wherein the fixed module integrates a plug-in that provides the basic necessary functions of the controller.

[0009] The replacement module may or may not integrate optional plugins.

[0010] Any integrated socket assembly formed by the fixed module and one or more replacement modules can be assembled to the corresponding position of the main housing.

[0011] Preferably, the plug-in modules integrating the basic essential functions on the fixed module include:

[0012] Positive and negative power plugs: Connect to the power source to supply power to the device;

[0014] Plug-in plastic housing: Connects to the instrument output cable.

[0015] Preferably, the optional functions integrated on the replacement module include one or more of the following: communication, torque, throttle, gear shifting, speed measurement, Hall effect sensors, front and rear lights, left and right turn signals, and one-button start.

[0016] The optional plug-in is a plug-in plastic shell.

[0017] Preferably, both the fixing module and the replacement module include a base, the interlocking plastic shell is integrated on the base, and the base located inside the interlocking plastic shell has reserved pin holes;

[0018] A connecting plate is fixedly installed inside the main housing. The connecting plate is provided with metal contacts corresponding to the ferrule. The connecting plate is electrically connected to the circuit board assembly.

[0019] The pin hole is equipped with a pin assembly, which includes a pin header and / or a spring pin; the pin header includes a straight pin header and / or a forward and reverse bent pin header, and one end of the spring core of the spring pin passes through the base from inside the housing and extends into the mating plastic housing, while the other end of the spring core contacts the metal contacts on the connecting plate.

[0020] Preferably, the fixing module is connected to the adjacent replacement module via a detachable structure, and the replacement module is connected to the adjacent fixing module and / or replacement module via a detachable structure.

[0021] Preferably, the detachable structure includes a snap fastener, a retaining ring, or a detachable connector.

[0023] Preferably, the fixing module further includes a cable storage box, which has a space for storing waterproof cables. The base of the fixing module has a through hole that allows the waterproof cables to pass through, and the waterproof cable connector is located on the side of the base of the fixing module away from the cable storage box.

[0024] Preferably, the peripheral edges of the fixing module and / or replacement module are provided with connection holes;

[0027] Compared with the prior art, the present invention has the following beneficial effects:

[0028] 1. This invention integrates a socket controller, allowing for the selection of different numbers of pins and mating shells based on different functions during the production stage. Compared to a full-function socket, this saves unnecessary wiring harnesses or connectors, reducing manufacturing costs. Furthermore, to meet different functional needs of users, it is not necessary to add a new mating connector for each functional configuration; simply replacing the mating shell on the integrated socket is sufficient, effectively reducing the difficulty of material management.

[0029] 2. By replacing the pin with a spring pin, the present invention can eliminate the welding process and improve production.

[0030] 3. This invention utilizes a unidirectional stretching self-locking function, so that the wire harness does not need to maintain tension at all times during the stretching process, and the wire harness will not automatically retract. When the wire harness needs to be retracted, the self-locking function can be released, and the turntable rotates to drive the wire harness to retract. The self-locking functions can be switched between each other, making the use of the wire harness more flexible.

[0031] 4. The present invention uses a spiral spring-loaded waterproof wire harness, which can be adjusted in length at will during installation, improving the convenience of connection with external connectors. The wire harness itself has a spring-loaded design, which can automatically retract into the wire storage box without affecting the internal circuit board. Attached Figure Description

[0051] The present invention will now be described in detail with reference to specific embodiments. These embodiments will help those skilled in the art to further understand the present invention, but do not limit the invention in any way. It should be noted that those skilled in the art can make several changes and improvements without departing from the concept of the present invention. These all fall within the protection scope of the present invention.

[0052] Example 1

[0053] like Figures 1 to 4 As shown, a modular integrated socket 1 controller according to the present invention includes an integrated socket 1 assembly, a main housing 2, a circuit board assembly 3, and a cover plate 6. The integrated socket 1 assembly is disposed at one end of the main housing 2, and the cover plate 6 is disposed at the other end of the main housing 2. The circuit board assembly 3 is disposed within the space formed by the integrated socket 1 assembly, the main housing 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 integrates plug-in modules with basic essential functions of the controller. The replacement module 102 integrates plug-in modules with optional functions, or may not integrate plug-in modules. 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 housing 2.

[0054] The integrated socket 1 assembly, consisting of a fixed module 101 and a replacement module 102, can be detachably installed at the corresponding position of the main housing 2. During controller manufacturing, the main housing 2, the circuit board assembly 3, and the cover plate 6 can be processed separately from the integrated socket 1 assembly and then assembled. Depending on different functional requirements, the integrated socket 1 assembly consisting of different replacement modules 102 can be selected, enabling mass production and convenient disassembly and assembly.

[0055] Specifically, the main housing 2 can be a hollow rectangle, made of plastic, and waterproof and shockproof. The circuit board is fixed to the reinforcing plate inside the main housing 2 or to the side wall of the main housing 2 using fasteners such as screws. The cover plate 6 can be made of plastic, and its peripheral edges are provided with connection holes. The cover plate 6 is assembled and connected to the main housing 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 housing 2. The peripheral edges of the fixing module 101 and / or the replacement module 102 are provided with connection holes. The integrated socket 1 assembly formed by the fixing module 101 and one or more replacement modules 102 is assembled and connected to the main housing 2 through the cooperation of fasteners and connection holes. In this embodiment, the fasteners preferably adopt the fixing screws 7 of the prior art.

[0056] More specifically, the essential functional connectors integrated on the fixed module 101 include: positive and negative power plugs 12: connected to the power supply to power the device; waterproof cable connector 13: connected to the motor output; and plug-in plastic housing 14: connected to the instrument output. Optional functions integrated on the replacement module 102 include one or more of the following: communication, torque, throttle, gear shifting, speed measurement, Hall effect sensors, front and rear lights, left and right turn signals, and one-button start. The connectors for these optional functions are plug-in plastic housings 14.

[0057] Furthermore, the fixing module 101 is connected to the adjacent replacement module 102 via a detachable structure, and the replacement module 102 is connected to the adjacent fixing module 101 and / or replacement module 102 via a detachable structure. The detachable structure includes a snap-fit, a retaining ring, or a detachable connector. Preferably, the side of the fixing module 101 connected to the replacement module 102 is a plane, the side of the replacement module 102 connected to the fixing module 101 and / or replacement module 102 is a plane, the side plane of the fixing module 101 can fit against the side plane of the replacement module 102, and the side plane of the replacement module 102 can fit against the side plane of the fixing module 101 or the side plane of another replacement module 102.

[0058] Furthermore, the integrated socket 1 assembly is electrically connected to the circuit board. Both the fixed module 101 and the replacement module 102 include a base 11, and a mating plastic shell 14 is integrated on the base 11. The base 11, located inside the mating plastic shell 14, has pre-drilled pin holes. A connecting plate 4 is fixedly installed inside the main housing 2. The connecting plate 4 has metal contacts corresponding to the ferrule, and the connecting plate 4 is electrically connected to the circuit board assembly 3.

[0059] The pin hole is fitted with a pin assembly 15, which includes a pin header and / or a spring pin 17.

[0060] In one feasible implementation: the pin header includes straight pin headers and / or bent pin headers.

[0061] In another feasible implementation: one end of the spring core of the spring pin 17 passes through the base 11 from the inside of the housing 2 and extends into the mating plastic housing 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 plastic housing 14 can house pin assemblies 15 with different numbers of pins, currently ranging from 2 to 8 pins, to accommodate different functions.

[0063] During installation, multiple pin holes are pre-drilled on the base 11. The pin assembly 15 on the plastic shell 14 can be inserted into the corresponding holes to connect with the base 11. Then, glue is poured into the sealing groove of the base 11 for sealing and waterproofing. The metal pins can be directly soldered to the circuit board assembly 3 or connected to it via electronic wires to achieve signal connection. Preferably, ordinary metal pins can be replaced with spring pins 17. The connecting plate 4 is pre-fixed inside the shell 2, with corresponding metal contacts pre-drilled on it. During installation, the integrated socket 1 can skip the soldering step, relying on the spring-loaded pins' own spring-loaded characteristics to press against the contacts of the connecting plate 4 to achieve signal connection.

[0064] The fixing module 101 also includes a cable storage box 18, which includes a space for storing waterproof cables. The base 11 of the fixing module 101 has a through hole that allows the waterproof cables to pass through. The waterproof cable connector 13 is located on the side of the base 11 of the fixing module 101 away from the cable storage box 18.

[0065] Based on this embodiment, those skilled in the art can further design the storage of the waterproof line to improve its storage effect.

[0066] Example 2

[0067] like Figures 1 to 6 As shown, based on Embodiment 1, a wiring harness retraction structure for a controller provided by the present invention includes an integrated socket 1 assembly, a main housing 2, a circuit board assembly 3, a cover plate 6, and a connector wiring harness. The integrated socket 1 assembly is disposed at one end of the main housing 2, the cover plate 6 is disposed at the other end of the main housing 2, and the circuit board assembly 3 is disposed within the space formed by the integrated socket 1 assembly, the main housing 2, and the cover plate 6.

[0068] The integrated socket 1 assembly includes a base 11 and a cable storage box 18. The cable storage box 18 includes a space for storing connector wire harnesses. The base 11 has a through hole that allows the connector wire harnesses to pass through. One end of the connector wire harness is connected to the circuit board assembly 3. The other end of the connector wire harness extends from the inside to the outside after passing through the through hole on the cable storage box 18 and the base 11. The end of the connector wire harness extending out of the base 11 forms a connector for connecting to the motor output wire.

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

[0070] In one embodiment: the connector harness includes a helical segment, which is disposed within the cable storage box 18 and is elastic. The connector harness includes a waterproof wire, and the sheath of the connector harness is made of a flexible material. The connector harness is spirally housed in the cable storage box 18, and its length meets basic usage scenarios. Furthermore, due to the elasticity of the helical segment, if the pulled-out connector harness is too long, it can retract into the cable storage box 18 under the elastic action of the helical segment, thus ensuring that the length of the connector harness is appropriate. The sheath of the waterproof wire is made of a flexible material and is injection molded in a spiral shape during the harness manufacturing process. The spiral segment of the harness can be orderly placed within the cable storage box 18, and the tail electronic wire is connected to the circuit board.

[0071] When the waterproof cable connector is connected to the motor cable, if the controller installation position exceeds the original distance or the connection position is not conducive to installation, the waterproof cable can be pulled outward to facilitate the connection between the controller and the motor. After installation, the cable harness can be released and it will naturally retract along the spiral path. The retracted cable harness is stored in the cable storage box 18 and will not interfere with the circuit board assembly 3 inside the housing 2 or damage the controller function.

[0072] In another embodiment: a winding reel 20 is rotatably disposed inside the cable storage box 18, and the connector wire harness is wound on the winding reel 20. The innermost coil of the connector wire harness is fixedly connected to the winding reel 20, and a one-way tension locking device is also provided on the winding reel 20. When the connector wire harness is pulled, the winding reel 20 rotates to unwind, and the connector wire harness is pulled out. A fixing post 181 is provided on the inner wall of the cable storage box 18, and the winding reel 20 is rotatably mounted on the fixing post 181.

[0073] Furthermore, the one-way tension locking device includes a ratchet 21, a pawl 23, and a spring limiting block 24. The ratchet 21 is fixedly connected to the winding reel 20. The pawl 23 is rotatably disposed inside the wire storage box 18, engaging with the ratchet 21. The spring limiting block 24 is disposed below the pawl 23 and contacts the pawl 23. A rotating shaft is provided on the pawl 23, rotatably mounted on the side wall of the wire storage box 18. One end of the rotating shaft extends out of the wire storage box 18 from the inside, and a lever is fixedly disposed on the end of the rotating shaft extending out of the wire storage box 18. The spring limiting block 24 includes a return spring and a limiting block 24. A slot is provided on the pawl 23, and a pressing plate is provided on the outside of the wire storage box 18, fixedly connected to the limiting block 24.

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

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

[0076] With the one-way limiting action of ratchet 21 and pawl 23, when the wire is unloaded, the user pulls the connector wire harness outward, and ratchet 21 and pawl 23 work together to control the winding reel 20 to rotate in one direction, and can lock the position of the winding reel 20.

[0077] Furthermore, a coil spring 22 is also provided inside 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 operator releases the pawl 23 and ratchet 21 from the winding reel 20 by using the lever and 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 implementation: the side wall of the cable storage box 18 is provided with a vertical waist-shaped groove and a horizontal waist-shaped groove; the lever can move along the direction of the horizontal waist-shaped groove, and the pressing plate can move along the direction of the vertical waist-shaped groove. When unlocking, the operator operates the pressing plate to move downward along the direction of the vertical waist-shaped groove, and operates the lever to move away from the ratchet 21 along the direction of the horizontal waist-shaped groove, until the limiting block 24 is embedded in the slot. At this time, the pawl 23 separates from the ratchet 21, and the one-way tension locking device releases the lock on the winding reel 20.

[0079] During the stretching process, the ratchet 21 rotates, engaging with the pawl 23 to form an intermittent unidirectional motion mechanism. Each time the wire harness is stretched out a small section, the ratchet 21 rotates one notch. With a relatively large number of teeth at intervals, the stretching is nearly stepless and uniform, resulting in a relatively smooth and controllable stretching speed without significant fluctuations. Each time the pawl 23 is moved, it engages between two teeth of the ratchet 21, creating a self-locking function. The wire can only be stretched outwards in one direction and cannot be reversed. Even when rotated inwards, the wire harness will not automatically retract into the cable storage box 18. When the wire harness is stretched too far and needs to be retracted, the pawl 23 is moved backwards. During this movement, due to the compressible spring below the limit block 24, the pawl 23's slot eventually engages above the limit block 24, separating the ratchet 21 and pawl 23, thus releasing the wire harness from locking. The inner end of the coil spring 22 is connected to the fixing post 181, and the outer end is connected to the winding reel 20. With the lock disengaged, pushing the wire harness inward, combined with the slight elasticity of the coil spring 22, causes the winding reel 20 to rotate, allowing the wire harness to automatically and smoothly retract. Pressing the limit block 24 down again and sliding the pawl 23 to reset, in conjunction with the ratchet 21, restores the self-locking function.

[0080] In a preferred embodiment: the upper surface of the limiting block 24 is spherical, the slot is a semi-circular groove, and the lower surface of the pawl 23 that contacts the limiting block 24 is an inclined plane.

[0081] The integrated socket 1 assembly has connection holes on its peripheral edge, and is assembled and connected to the main housing 2 through the cooperation of fasteners and connection holes. The cover plate 6 has connection holes on its peripheral edge, 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.
