Abstract

This application discloses a connection structure and locking method for a handheld component and a functional component. The structure utilizes a return spring to push a sliding member to normally seal the slot, automatically shielding the internal power terminals and achieving dynamic dust and water protection. This effectively prevents moisture and dust from entering when idle, improving the overall protection capability and service life. The device achieves synchronous control of locking and power-on via a single sliding button, with the unlocking sequence being mechanical unlocking followed by circuit disconnection, completely eliminating hot-plugging while powered on, preventing arcing and electrical damage, and enhancing safety. The structure employs a graded decoupling design of magnetic pre-fixation and mechanical hard locking. When not powered on, temporary pre-positioning is achieved through magnetic attraction, preventing component detachment and facilitating assembly. During operation, a limiting member engages to withstand external forces, ensuring a stable and durable connection while balancing ease of operation and structural reliability.

Description

Technical Field

[0001] This application relates to a modular power supply connection structure, and in particular to a connection structure between a handheld component and a functional component, and a locking method thereof. Background Technology

[0002] With the rapid development of handheld electronic devices, personal care devices, and portable small household appliances, users' demand for multifunctional integrated devices is increasing. Existing handheld devices typically employ a "single main unit paired with a single functional head" structure, or although they adopt a detachable modular design, they often suffer from the following technical shortcomings in practical use: First, existing detachable functional heads and handheld power supply terminals mostly use a simple plug-and-play connection. When the device is not powered on or in standby mode, the interface is easily exposed to dust and moisture. Second, existing connection structures usually require users to perform two separate operations: "mechanical locking" and "circuit switching," which is cumbersome and can easily lead to safety hazards such as "hot-swapping" or "starting without locking." Third, existing handheld modules are mostly custom-designed and cannot achieve broad compatibility and modular universal adaptation of a single power supply handle for various types and functions of execution modules.

[0003] Therefore, how to provide a compact connection structure for handheld components and functional components that supports synchronous control of linkage sliding parts and has safe timing coordination has become a technical problem that urgently needs to be solved by those skilled in the art. Summary of the Invention

[0004] The purpose of this invention is to overcome the shortcomings of the prior art and provide a connection structure and locking method for handheld components and functional components, thereby solving the problems of long-term exposure of existing plug interfaces, wide compatibility with various types and functional execution modules, and modular universal adaptation.

The sliding member is supported by the reset elastic member and blocks the opening under normal conditions. When the functional component is inserted, it moves downward against the elastic force of the reset elastic member so that the handheld component and the functional component can be connected and connected. A mechanical locking mechanism is provided inside the handheld component, including a limiting member that can move in a direction intersecting the insertion direction. The limiting member is used to engage the functional component under drive to achieve a limiting lock. A linkage slider is disposed on the handheld component.

[0009] In a preferred embodiment, the fixed bracket and the functional component are respectively provided with magnetic attracting elements that magnetically attract each other, and the magnetic attraction generated when the two are connected is used for pre-fixation.

[0010] In a preferred embodiment, the sum of the rebound force of the reset elastic member in the compressed state and the self-weight of the functionalized component is less than the axial magnetic attraction force between the magnetic members.

[0011] In a preferred embodiment, the mechanical locking mechanism further includes a fixed cylinder, a sleeve, and a locking spring. The limiting member is a movable rod, and the locking spring is sleeved on the movable rod and pushes it to retract in its normal state.

[0012] In a preferred embodiment, the linkage slider is a sliding button that can slide vertically. The upper trigger protrusion on its back serves as the locking drive part, and the lower trigger protrusion serves as the switch trigger part. A transmission inclined surface is provided between the locking drive part and the limiting member to realize the conversion from vertical movement to horizontal movement. The handheld component is provided with a limiting bracket inside for limiting the sliding button to a certain position.

[0013] In a preferred embodiment, when the linkage sliding member is activated, the locking drive unit withdraws its drive on the mechanical locking mechanism before the switch trigger unit, so that the limiting member retracts first to release the mechanical locking state, and then the switch trigger unit cuts off the power supply circuit.

The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0026] Please refer to Figures 1 to 15 This embodiment provides a connection structure between a handheld component and a functional component and a linkage control method thereof, including a handheld component 100 and a functional component 200.

[0027] The handheld component 100 includes a housing 101 and a cover 102. The cover 102 is fixed to the top of the housing 101. The cover 102 has an axial through slot 103, which is the opening at the top of the handheld component 100.

[0028] The housing 101 contains a battery 104 and a circuit board 105. The battery 104 and the circuit board 105 are electrically connected. The circuit board 105 is provided with a switch button 106 and a power-on female connector 107. The power-on female connector 107 is arranged axially toward the slot 103.

[0029] Among them, the power-conducting female connector 107 is a specific form of electrical connection terminal used to realize the transmission of electrical energy or signals.

[0030] Please refer to Figure 9 The housing 101 has a fixed bracket 108 inside, which is located below the cover 102 and is fixedly connected to the inner wall of the housing 101. The fixed bracket 108 has a sliding groove 109 extending in the vertical direction.

[0031] The fixed bracket 108 is provided with a sliding member inside, which is specifically a sliding bracket 110; the side wall of the sliding bracket 110 is provided with a protrusion 111, which is embedded in the sliding groove 109, so that the sliding bracket 110 can slide up and down in the vertical direction inside the fixed bracket 108 along the sliding groove 109.

[0032] The sliding bracket 110 can slide inside the housing 101 along the insertion direction to close the opening of the handheld component 100 when not assembled and to be pressed down when assembled.

[0033] The lower part of the sliding bracket 110 has a ring-shaped protrusion 112, and the bottom of the fixed bracket 108 is provided with a groove 113. The ring-shaped protrusion 112 is located above the groove 113. A reset elastic element is provided inside the groove 113. The reset elastic element is specifically a reset spring 114. The bottom end of the reset spring 114 abuts against the bottom surface of the groove 113, and the top end of the reset spring 114 abuts against the bottom surface of the ring-shaped protrusion 112.

[0034] Both the sliding bracket 110 and the fixed bracket 108 have an axially extending channel 115 at their center, and the power-conducting female connector 107 passes through the channel 115.

[0035] The functional component 200 has a downward protruding protrusion 201 at its lower part. The shape of the protrusion 201 is adapted to the slot 103 of the cover 102. The shape of the protrusion 201 and the slot 103 restricts the insertion to one direction only, which plays a role in preventing fooling and misinsertion. A power male connector 202 is provided on the bottom surface of the protrusion 201.

[0036] Please refer to Figures 8 to 12 When the protrusion 201 of the functional component 200 is inserted into the slot 103, the bottom surface of the protrusion 201 presses the sliding bracket 110 and slides downward along the fixed bracket 108, so that the power-conducting male connector 202 passes through the channel 115 and connects with the power-conducting female connector 107; the top of the handheld component 100 is provided with an opening, and the sliding bracket 110 is supported by the return spring 114 and blocks the opening under normal conditions; when the functional component 200 is inserted, it moves downward against the elastic force of the return spring 114 so that the power-conducting terminals are connected.

[0037] After the functional component 200 is pulled upward, the reset spring 114 releases its elastic force to push the annular protrusion 112 upward, causing the sliding bracket 110 to slide upward and reset, so that the top of the sliding bracket 110 closes the slot 103 of the cover 102.

[0038] The magnetic components include: a lower magnetic component 116 disposed inside the upper part of the fixed bracket 108, and an upper magnetic component 203 disposed at a corresponding position inside the protrusion 201 of the functional component 200, with the lower magnetic component 116 and the upper magnetic component 203 being vertically corresponding.

[0039] When the functional component 200 is inserted into the docking position, the fixed bracket 108 and the corresponding position of the functional component 200 are respectively provided with magnetic suction components that magnetically attract each other, namely the lower magnetic suction component 116 and the upper magnetic suction component 203. The magnetic attraction force generated when the two are docked is used for pre-fixing.

[0040] At this time, the return spring 114 is in a compressed state. The sum of its rebound force and the weight of the functional component 200 is less than the axial magnetic attraction force between the lower magnetic accumulator 116 and the upper magnetic accumulator 203, thereby ensuring that the functional component 200 will not be lifted by the return spring 114 or fall off by itself after being released.

[0041] The magnetic attraction force is set to maintain the functional component 200's own weight from falling off, but it is insufficient to withstand external pulling force during operation and is only used for pre-positioning.

[0042] In other embodiments, the lower magnetic accumulator 116 and the upper magnetic accumulator 203 can be arranged as an integral ring magnet along the circumference, or multiple small magnets can be evenly distributed along the circumference; the magnetic attraction force can be adjusted as needed according to the self-weight of the functional component 200, so as to ensure the pre-positioning effect without increasing the resistance of the pull-out operation.

[0043] Please refer to Figures 9 to 13 A fixed cylinder 117 is provided on one side of the fixed bracket 108, and the fixed cylinder 117 is fixedly connected to the fixed bracket 108. The fixed cylinder 117 penetrates the side wall of the fixed bracket 108, connecting the internal space and the external space of the fixed bracket 108. A sleeve 118 is fixedly provided inside the fixed cylinder 117. A moving rod 120 and a locking spring 119 are provided inside the sleeve 118. The locking spring 119 is sleeved on the moving rod 120. The two ends of the locking spring 119 abut against the inner wall of the sleeve 118 and the tail of the moving rod 120, respectively. The cross section of the moving rod 120 is cross-shaped. The locking spring 119 abuts against the intersection of the cross-shaped part. Under normal conditions, the locking spring 119 pushes the moving rod 120 to retract into the sleeve 118. Under moving conditions, the front end of the moving rod 120 can pass through the fixed cylinder 117 and extend into the internal space of the fixed bracket 108.

[0044] The lower protrusion 201 of the functional component 200 has a locking groove 204 on its side wall. The size of the locking groove 204 is adapted to the front end of the moving rod 120, and the position of the locking groove 204 is coaxially corresponding to the position of the moving rod 120.

[0045] When the moving rod 120 extends outward, its front end can be inserted into the locking groove 204 on the side wall of the protrusion 201, restricting the axial displacement of the functional component 200 along the insertion direction, and realizing the limit locking and snapping.

[0046] The fixed cylinder 117, sleeve 118, moving rod 120 and locking spring 119 together constitute the mechanical locking mechanism. The moving rod 120 serves as a limiting member and can move in a direction intersecting the insertion direction.

[0047] In other embodiments, the front end of the moving rod 120 may be provided with a guide chamfer to facilitate smooth insertion into the locking groove 204; the sleeve 118 and the fixed bracket 108 may be provided as an integral molding structure or in the form of separate assembly; a set of active locking structures may be provided on different side walls of the fixed bracket 108 to further improve the locking firmness.

[0048] The side wall of the outer casing 101 is provided with a side sliding groove 121, and a linkage sliding component is slidably engaged on the side sliding groove 121. The linkage sliding component is a sliding button 122, which can slide up and down in the vertical direction. The back of the sliding button 122 facing the inside of the outer casing 101 is provided with an upper trigger protrusion 123 and a lower trigger protrusion 124. The lower trigger protrusion 124 serves as a switch trigger part, and its position corresponds vertically to the switch button 106 on the circuit board 105. The upper trigger protrusion 123 serves as a locking drive part, and its position corresponds to the tail position of the moving rod 120.

[0049] The upper triggering point 123 and the tail of the moving rod 120 are provided with a matching transmission inclined surface. The linkage sliding component realizes the conversion of motion trajectory through the transmission inclined surface, which is used to complete the smooth conversion from vertical motion to horizontal motion.

[0050] The sliding button 122 has a protrusion 125 on its side, and a limiting bracket 126 is provided inside the housing 101. The limiting bracket 126 is fixedly connected to the inner wall of the housing 101. Two limiting grooves 127 are provided on the limiting bracket 126. The two limiting grooves 127 are arranged vertically and are adapted to the protrusion 125 on the side of the sliding button 122.

[0051] When the sliding button 122 is pushed upward, the lower trigger point 124 moves upward with the sliding button 122 and triggers the switch button 106 on the circuit board 105, thus turning on the power supply circuit. The upper trigger point 123 moves upward synchronously, and through the cooperation of the transmission inclined plane, the vertical upward thrust is converted into a horizontal outward component force, which pushes the tail of the moving rod 120, so that the moving rod 120 overcomes the elastic force of the locking spring 119 and pushes outward, inserting into the locking groove 204 of the functional component 200 to complete the limit engagement. When the protrusion 125 on the side of the sliding button 122 is engaged in the upper limit groove 127, the sliding button 122 remains in a fixed position and continues to press the moving rod 120 through the upper trigger point 123 to maintain the locked state.

[0052] When the sliding button 122 is pushed downwards and reversed, causing the protrusion 125 to engage with the lower limiting groove 127, the sliding component moves in tandem. The upper trigger point 123 retracts its drive on the mechanical locking mechanism before the lower trigger point 124. The moving rod 120 retracts first under the action of the locking spring 119, releasing the mechanical lock. Subsequently, the lower trigger point 124 cuts off the power supply circuit, safely releasing the power supply and achieving the timing coordination of power-off and unlocking.

[0053] In other embodiments, the protrusion 125 on the side of the sliding button 122 can be configured as an elastic buckle structure, and the two limiting grooves 127 can be configured as arc-shaped slots to provide a clear gear operation feel; the exposed surface of the sliding button 122 can be provided with an anti-slip texture to improve the convenience and feel of operation.

[0054] The power-conducting female connector 107 and the power-conducting male connector 202 together form an electrical connection interface. After they are connected and connected, power can be transmitted between the handheld component 100 and the functional component 200.

[0055] After the functional component 200 is inserted and locked, the electrical connection interface remains stably conductive, capable of transmitting electrical energy, as well as control signals and data signals.

[0056] In other embodiments, the power-on female connector 107 and the power-on male connector 202 can adopt a flexible pin structure or a standard connector interface; in addition to physical contact, the electrical connection can also adopt a wireless power-on coil combined with near-field communication to realize wireless power and signal transmission, in which case the mechanical locking structure is still retained; the functional component 200 can be replaced with different functional modules according to actual usage requirements, and the size of the lower protrusion 201 of each functional module is consistent with the position of the power-on male connector 202, so that one handheld component 100 can be adapted to multiple functional components 200.

[0057] The handheld component 100 can be a mobile power bank handle with a built-in energy storage battery 104, a portable energy storage power supply handle, a main control handle with an integrated control chip and drive circuit, or a data host or sensor acquisition host with data relay and signal acquisition functions. The core of the handheld component 100 is an internal cavity that can integrate a fixed bracket 108, a sliding bracket 110, a locking structure and an electrical connection interface, and provide power or control signal output to the functional component 200.

[0058] Among them, the functional component 200 can be various small handheld functional execution devices, including but not limited to: household appliance functional heads such as hair dryer modules, atomizing humidification modules, LED lighting modules, and fan modules; personal care functional heads such as facial cleansing brush heads, beauty import heads, and hair removal and care heads; power tool functional heads such as mini polishing heads, electric screwdriver bits, and small drilling bits; and electronic functional modules such as data storage modules, Bluetooth communication modules, and environmental sensing modules.

[0059] The functional components 200 with different functions all have the same external dimensions of the lower protrusion 201, the position and specifications of the power male connector 202, and the position and dimensions of the side wall locking groove 204. They can all be plugged into and cooperate with the same handheld component 100 to realize a modular use scheme in which one power supply main body can adapt to multiple functional modules.

[0060] This application also provides a linkage control method for the above-mentioned connection structure, which is based on the aforementioned plug-in locking structure. It synchronously completes power supply switching and mechanical locking / unlocking through a single operating element. The specific control process is as follows: Initial standby procedure: The sliding member seals the opening under the action of the reset elastic member, the linkage sliding member is in the initial position, the power supply circuit is disconnected, and the limit member is in the released state. Specifically: the sliding member (i.e., the sliding bracket 110) inside the handheld component 100 is in the sealed position, the reset spring 114 at the bottom of the fixed bracket 108 pushes the annular protrusion 112 of the sliding bracket 110 upward, so that the sliding bracket 110 is held in the highest position along the slide groove 109, the top of the sliding bracket 110 is flush with the groove 103 of the cover 102, the opening of the groove 103 is closed, and the power-on female connector 107 is hidden inside.

[0061] At this time, the sliding button 122 is in the lower initial position, and the side protrusion 125 is positioned by engaging the limiting groove 127 below the limiting bracket 126; the moving rod 120 is kept in the retracted state by the locking spring 119 inside the sleeve 118, and the front end does not extend into the insertion path; the switch button 106 on the circuit board 105 is not triggered, the power supply circuit is disconnected as a whole, and the mechanical locking mechanism is in the released state.

[0062] Connecting and connecting steps: Insert the functional component 200 into the opening, push the slider down and connect the power terminals.

[0063] Specifically, the protrusion 201 at the lower part of the functional component 200 is inserted into the slot 103 of the handheld component 100. After the bottom surface of the protrusion 201 contacts the top of the sliding bracket 110, the sliding bracket 110 is pushed vertically down along the slide groove 109 and an electrical connection is achieved, so that the sliding bracket 110 moves down and compresses the return spring 114 to store energy.

[0064] As the insertion depth increases, the male connector 202 passes through the central channel 115 between the sliding bracket 110 and the fixed bracket 108 and gradually mates with the female connector 107. When the connector is inserted to the mating position, the male connector 202 and the female connector 107 are completely physically attached. At the same time, the lower magnetic accumulator 116 in the fixed bracket 108 and the upper magnetic accumulator 203 in the functional component 200 are aligned vertically to generate an axial attraction force.

[0065] After the functional component 200 is released, the attraction of the lower magnetic 116 and the upper magnetic 203 cancels out the weight of the component and the elastic force of the return spring 114 in the compressed state, so the functional component 200 will not fall off by itself, achieving temporary pre-fixation in the off state; at this time, the connection is maintained by magnetic attraction only, and it can still be separated under a large axial tensile force, without forming a reliable mechanical lock.

[0066] Power-on locking procedure: Operate the linkage slider to the locking position, the switch trigger unit triggers the power supply circuit to conduct, and at the same time the locking drive unit drives the limit piece to engage in the functional component to complete the mechanical locking.

[0067] Specifically: After completing the pre-positioning, operate a single operating component, push the sliding button 122 upward to the locking position, and the side protrusion 125 disengages from the lower limiting groove 127, slides to the upper limiting groove 127 and engages.

[0068] During the upward movement of the sliding button 122, on the one hand, the lower trigger protrusion 124 on the back moves upward and presses against the switch button 106 on the circuit board 105, triggering the power supply circuit between the battery 104 and the functional component 200, thus completing the power supply circuit. On the other hand, the upper trigger protrusion 123 on the back moves upward synchronously, converting the vertical upward thrust into a horizontal outward component through the transmission inclined plane, overcoming the elastic force of the locking spring 119 inside the sleeve 118, and pushing the moving rod 120 outward along the fixed cylinder 117, engaging the locking groove 204 on the side wall of the functional component 200, and driving the mechanical locking mechanism to limit and lock the functional component 200. At this time, the functional component 200 is blocked by the moving rod 120 and cannot be pulled out axially, the connection state is completely locked, and it can withstand the pulling and vibration forces during operation.

[0069] Power-off unlocking steps: Reverse operation of the linkage slider, the locking drive unit first drives the limit piece to retract and release the mechanical lock, then the switch trigger unit cuts off the power supply circuit, and after the functional component is pulled out, the reset elastic element drives the slider to reset the seal.

[0070] Specifically: When the module needs to be replaced after use, reverse the operation of the single operating component, push the sliding button 122 downwards, and the side protrusion 125 disengages from the upper limiting groove 127, slides back into the lower limiting groove 127 and locks in, returning to the initial position. During the downward movement of the sliding button 122, the upper trigger point 123 first withdraws the pushing force on the moving rod 120. Under the action of the tail locking spring 119, the moving rod 120 retracts into the sleeve 118 first, and the front end exits from the locking groove 204 of the functional component 200, first releasing the limiting state of the mechanical locking mechanism; then the lower trigger point 124 leaves the switch button 106 to cut off the power supply circuit, the power supply state is safely released, and the functional component 200 is de-energized and stops working.

[0071] At this point, the functional component 200 returns to its pre-fixed state solely by magnetic attraction. Finally, by applying an upward pulling force to overcome the magnetic attraction, the functional component 200 can be pulled out of the slot 103. After the sliding bracket 110 loses its downward pressure, the bottom return spring 114 releases its elasticity, pushing the sliding bracket 110 upward along the slide groove 109 back to its highest position. The top re-closes the slot 103 of the cap 102, and the device returns to its initial standby state, waiting for the next insertion and use.

[0072] In other embodiments, the magnetic attraction force of the lower magnetic component 116 and the upper magnetic component 203 can be adjusted according to usage requirements to adapt to functional components 200 with different weights; the damping feel of the gear limit groove 127 can be adjusted to adapt to different operating force requirements; the electrical connection method can be replaced with a wireless transmission scheme, while the mechanical locking logic remains unchanged, only the connection step of the physical conductive terminals is eliminated.
