Description

Technical Field

[0001] This invention relates to the field of charging plugs, and more specifically, to an electric bicycle charging plug with a locking mechanism. Background Technology

[0002] Electric bicycles are vehicles that use batteries as auxiliary power and are based on ordinary bicycles, equipped with motors, controllers, batteries, throttles, brake levers, and display systems. In China, electric bicycles were first developed in the 1980s and their structure was continuously improved. It was not until the beginning of this century that electric bicycles were widely promoted and entered countless households.

[0003] Most existing electric bicycles are charged by using a charging plug and a charging socket. Currently, the charging plug and the charging socket are mostly connected by an interference fit, which is extremely unstable during charging and is prone to falling off or loosening, resulting in low safety during charging.

[0004] Chinese patent CN219067337U discloses an electric bicycle charging plug with a locking mechanism. During charging, the plug body is aligned with the socket body, and the hollow plug is inserted into the socket to form a charging structure. The slotted side of the locking lever is inserted into the slot of the locking block. The locking head, under the elastic action of the locking lever, enters the slot, thus forming a locking structure to prevent it from falling off or loosening during charging, thus affecting charging safety. However, the sliding friction caused by the locking head inside the slot can lead to wear and a reduction in its size, resulting in a less secure connection. Furthermore, the locking lever is prone to breakage during use, rendering the self-locking structure unusable. Summary of the Invention

[0005] In view of the problems existing in the prior art, the purpose of this invention is to provide an electric bicycle charging plug with a locking mechanism.

[0006] To solve the above problems, the present invention adopts the following technical solution.

[0007] An electric bicycle charging plug with a locking mechanism includes a handle and a socket assembly. A plug is fixedly connected to one side of the handle, and a conductive post is axially symmetrically connected to one side of the inner surface of the plug. A conductive wire is fixedly connected to one side of the handle, and a self-locking component for locking the plug is provided at the middle of the upper surface of the handle.

[0008] The self-locking assembly includes a fixing rod fixed to the upper and lower surfaces of the handle and a metal retaining ring fixed to one side of the socket assembly. The outer surface of the fixing rod is slidably connected with a hook, and a first spring is sleeved on the outer surface of the fixing rod.

[0009] Furthermore, the socket assembly includes a socket housing, a fixed frame is fixedly connected to one side of the socket housing, a fixed block is fixedly connected to one side of the inner surface of the socket housing, and the fixed block has axially symmetrically formed insertion holes inside.

[0010] Furthermore, a limit block is fixedly connected to the top of the fixing rod, the hook is located above the first spring, and one side of the hook is inclined.

[0011] Furthermore, the handle is internally provided with a thrust assembly for assisting in pulling out the plug. The thrust assembly includes a cavity formed in the middle of the handle's interior. A squeezing rod is slidably connected to the top and bottom of the inner surface of the cavity. A squeezing plate is fixedly connected to the top of the squeezing rod. A hinge rod is hinged to the bottom of the squeezing rod. A first telescopic rod is hinged to the other end of the hinge rod. Two push rods are slidably connected to the middle of one side of the inner surface of the cavity. A push plate is fixedly connected to one side of the two push rods. A second spring is fixedly connected to the top and bottom of the squeezing plate near the push rods.

[0012] Furthermore, one side of the first telescopic rod extends into the interior of the top rod, the top of the compression rod extends out of the interior of the cavity, and one side of the top rod extends into the interior of the plug.

[0013] Furthermore, a groove is provided on the inner surface of the plug near the handle, and two spring grooves are provided on one side of the inner surface of the groove. The push plate is located inside the groove, and the second spring is located inside the spring groove. One side of the second spring is fixedly connected to the inner surface of the spring groove. The side of the push plate away from the push rod is flush with one side of the inner surface of the plug.

[0014] Furthermore, a transmission assembly is slidably disposed on one side inside the extrusion plate. The transmission assembly includes a transmission rod that slides on one side inside the extrusion plate. A first limiting plate is fixedly connected to the top of the transmission rod, a second limiting plate is fixedly connected to the bottom of the transmission rod, and a third spring is sleeved on the outer surface of the transmission rod.

[0015] Furthermore, the first limiting plate is located above the extrusion plate, and the first limiting plate is in contact with the upper surface of the extrusion plate. The third spring is located between the extrusion plate and the second limiting plate, and the third spring is in a taut state.

[0016] Furthermore, the front and rear sides of the handle are provided with a shielding component for shielding and protecting the plug. The shielding component includes a fixing sleeve fixed to the front and rear sides of the handle. A fourth spring is fixedly connected to one side of the inside of the fixing sleeve. A second telescopic rod is fixedly connected to one side of the fourth spring. A slider is fixedly connected to one side of the second telescopic rod. A shielding plate is fitted on the outer surface of the slider. A groove is opened on one side of the shielding plate. A magnet is fixedly connected to one side of the shielding plate.

[0017] Furthermore, the slider slides inside the groove, the magnet is embedded inside the shielding plate, and the two shielding plates are arranged with opposite poles facing each other. The slider and the groove have a T-shaped cross-section.

[0018] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0019] 1. This solution incorporates a self-locking component. Under the elastic force of the first spring, the hook is pushed upwards, locking into the metal retaining ring. This ensures sufficient stability when the plug and socket are connected. Compared to existing technologies, the wear between the hook and metal retaining ring is minimal during use. Even if there is wear on the beveled edge of the hook, it will not affect the locking effect between the metal retaining ring and the hook. Furthermore, the metal retaining ring will not break, preventing the plug and socket from failing to self-lock.

[0020] 2. This solution incorporates a thrust assembly. By pressing the two compression plates with the thumb and forefinger, a transmission push rod pushes the push plate against the surface of the fixing block, applying a thrust away from the fixing block. Combined with manual pulling, this allows the plug to be easily pulled out of the socket housing without constantly shaking the plug to reduce friction. This significantly extends the lifespan of the conductive components inside the socket, making plug removal easier and more efficient.

[0021] 3. This solution incorporates a transmission component, which not only releases the self-locking state but also applies a pushing force to the push plate, making it easier to pull the plug out of the socket housing. By linking the self-locking component and the pushing component through the various parts of the transmission component, the number of steps required to pull out the plug is reduced, eliminating the drawbacks of operating the plug with both hands. It can be operated with just one hand, improving the convenience of the user experience. Attached Figure Description

[0037] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0038] Please see Figures 1 to 8An electric bicycle charging plug with a locking mechanism includes a handle 1 and a socket assembly 2. A plug 4 is fixedly connected to one side of the handle 1. A conductive post 7 is symmetrically connected to one side of the inner surface of the plug 4. A conductive wire 3 is fixedly connected to one side of the handle 1. A self-locking assembly 5 for self-locking the plug 4 is provided in the middle of the upper surface of the handle 1.

[0039] like Figure 2-4 As shown, the self-locking assembly 5 includes a fixing rod 51 fixed to the upper and lower surfaces of the handle 1 and a metal retaining ring 54 fixed to one side of the socket assembly 2. The outer surface of the fixing rod 51 is slidably connected with a hook 52, and the outer surface of the fixing rod 51 is fitted with a first spring 53.

[0040] The socket assembly 2 includes a socket housing 21, a fixed frame 24 is fixedly connected to one side of the socket housing 21, and a fixed block 23 is fixedly connected to one side of the inner surface of the socket housing 21. The fixed block 23 has symmetrically arranged socket holes 22 inside.

[0041] A limit block is fixedly connected to the top of the fixed rod 51, and the hook 52 is located above the first spring 53, with one side of the hook 52 being inclined.

[0042] When charging an electric bicycle, the plug 4 is inserted into the socket housing 21, so that the plug 4 fits onto the outer surface of the fixing block 23. The two conductive posts 7 are inserted into the socket 22, thereby connecting the circuit and allowing the electric bicycle to be charged. When the plug 4 is inserted into the socket housing 21, the hook 52 moves towards the fixing frame 24. The inclined side of the hook 52 contacts one side of the metal retaining ring 54. The hook 52 slides on the inclined side of the metal retaining ring 54 and slides downward on the outside of the fixing rod 51. As the hook 52 continues to move closer to the fixing frame 24, the hook 52 moves completely into the metal retaining ring 54. Below the retaining ring 54, the top of the hook 52 slides below the metal retaining ring 54. Under the elastic force of the first spring 53, the hook 52 is pushed upward, so that the hook 52 is locked inside the metal retaining ring 54. This ensures that the plug 4 and the socket housing 21 are sufficiently stable when plugged in. During the use of the hook 52 and the metal retaining ring 54, the wear between the hook 52 and the metal retaining ring 54 is less than that of the prior art. Even if there is wear on the bevel of the hook 52, it will not affect the locking effect between the metal retaining ring 54 and the hook 52. Moreover, the metal retaining ring 54 will not break, avoiding the situation where the plug 4 and the socket housing 21 cannot lock themselves.

[0043] like Figure 5As shown, the handle 1 is provided with a push assembly 55 for assisting in pulling out the plug 4. The push assembly 55 includes a cavity 558 opened in the middle of the inside of the handle 1. A pressing rod 553 is slidably connected to the top and bottom of the inner surface of the cavity 558. A pressing plate 551 is fixedly connected to the top of the pressing rod 553. A hinge rod 552 is hinged to the bottom of the pressing rod 553. A first telescopic rod 557 is hinged to the other end of the hinge rod 552. Two push rods 554 are slidably connected to the middle of one side of the inner surface of the cavity 558. A push plate 555 is fixedly connected to one side of the two push rods 554. A second spring 556 is fixedly connected to the top and bottom of the pressing plate 551 near the push rods 554.

[0044] One side of the first telescopic rod 557 extends into the interior of the top rod 554, the top of the compression rod 553 extends out of the interior of the cavity 558, and one side of the top rod 554 extends into the interior of the plug 4.

[0045] A groove is provided on the inner surface of the plug 4 near the handle 1, and two spring grooves are provided on one side of the inner surface of the groove. The push plate 555 is located inside the groove, and the second spring 556 is located inside the spring groove. One side of the second spring 556 is fixedly connected to the inner surface of the spring groove. The side of the push plate 555 away from the push rod 554 is flush with one side of the inner surface of the plug 4.

[0046] In daily use, when the electric bicycle is fully charged, the plug 4 needs to be unplugged from the socket housing 21. However, when unplugging the plug 4 from the socket housing 21, due to the large friction between the plug 4, the socket housing 21, and the fixing block 23, it is necessary to shake the plug up, down, left, and right repeatedly to pull it out. However, prolonged shaking will cause the conductive post 7 to shake continuously inside the socket 22, causing the diameter of the socket 22 to increase continuously. This can easily lead to poor contact between the conductive post 7 and the conductive part inside the socket 22, or even prevent the conductive part inside the socket 22 from contacting the conductive post 7, thus reducing the service life of the socket housing 21.

[0047] Therefore, when the plug 4 and the socket housing 21 are connected, the push plate 555 and the fixing block 23 are in contact and fit together. When the plug 4 is pulled out of the socket housing 21, the thumb and forefinger press the two squeezing plates 551, and the two squeezing plates 551 move closer to each other, driving the two squeezing rods 553 to move into the cavity 558. The squeezing rods 553 push the first telescopic rod 557 to move inside the top rod 554. The two top rods 554 push the push plate 555 to apply a pushing force to the surface of the fixing block 23. The forces are mutual, thus applying a pushing force to the plug 4 in a direction away from the fixing block 23. Combined with the manual pulling force, the plug 4 can be easily pulled out of the socket housing 21 without constantly shaking the plug 4 to reduce friction. This greatly improves the service life of the conductive parts inside the socket 22, and makes it easier and more efficient to pull out the plug 4.

[0048] like Figure 6 As shown, a transmission assembly 559 is slidably disposed on one side inside the extrusion plate 551. The transmission assembly 559 includes a transmission rod 5593 that slides on one side inside the extrusion plate 551. A first limiting plate 5591 is fixedly connected to the top of the transmission rod 5593, a second limiting plate 5592 is fixedly connected to the bottom of the transmission rod 5593, and a third spring 5594 is sleeved on the outer surface of the transmission rod 5593.

[0049] The first limiting plate 5591 is located above the extrusion plate 551, and the first limiting plate 5591 is in contact with the upper surface of the extrusion plate 551. The third spring 5594 is located between the extrusion plate 551 and the second limiting plate 5592, and the third spring 5594 is in a taut state.

[0050] When unplugging plug 4, one hand needs to press the two hooks 52 to separate the hooks 52 from the metal retaining ring 54 and release the self-locking state of plug 4. The other hand needs to press the two pressing plates 551 to drive the push plate 555 to apply pressure to the fixing block 23. The two-hand operation increases the number of steps to unplug plug 4, which is inconvenient for users.

[0051] When disconnecting the plug 4 and the socket housing 21, press the two pressing plates 551 together. As the pressing plates 551 move downward, they compress the third spring 5594. The third spring 5594 compresses the hook 52 through the second limiting plate 5592. At this time, the deformation force of the third spring 5594 is greater than that of the first spring 53. Therefore, the second limiting plate 5592 pushes the hook 52 to slide downward on the outer surface of the fixing rod 51, causing the hook 52 to disengage from the metal retaining ring 54. At the same time, when the pressing plate 551 moves the pressing rod 553, in order to avoid the pressing plate 555 generating a synchronous pushing force, which could cause the hook 52 to not completely move out of the metal retaining ring 54 and become stuck, the pressing rod 553 is pressed while the pressing plate 551 is moving. Pushing the first telescopic rod 557 to slide a certain distance inside the top rod 554 does not generate a thrust on the top rod 554. When the hook 52 is completely removed from the inside of the metal retaining ring 54, the hook 52 stops moving, and the pressing plate 551 continues to move. At this time, the third spring 5594 is compressed to ensure the normal movement of the pressing plate 551. Through the transmission, the first telescopic rod 557 moves to the very end inside the top rod 554, which generates a thrust on the push plate 555. This makes it easier to pull the plug 4 out of the socket housing 21. By linking the self-locking component 5 and the thrust component 55 through the transmission component 559, the number of steps to pull out the plug 4 can be reduced, reducing the disadvantages of operating the plug 4 with both hands. It can be operated with only one hand, improving the convenience of the user experience.

[0052] like Figure 7-8 As shown, the front and rear sides of the handle 1 are provided with a shielding component 6 for shielding and protecting the plug 4. The shielding component 6 includes a fixing sleeve 65 fixed to the front and rear sides of the handle 1. A fourth spring 66 is fixedly connected to one side inside the fixing sleeve 65. A second telescopic rod 64 is fixedly connected to one side of the fourth spring 66. A slider 63 is fixedly connected to one side of the second telescopic rod 64. A shielding plate 61 is sleeved on the outer surface of the slider 63. A groove 62 is opened on one side of the shielding plate 61. A magnet 67 is fixedly connected to one side of the shielding plate 61.

[0053] The slider 63 slides inside the groove 62, the magnet 67 is embedded inside the shielding plate 61, and the two shielding plates 61 are arranged with opposite poles facing each other. The cross-section of the slider 63 and the groove 62 is T-shaped.

[0054] When plug 4 is idle, it is usually exposed to the outside, which can cause small stones to get inside. These stones can become stuck between the two conductive posts 7, making it difficult to remove them and rendering plug 4 unusable. Therefore, when plug 4 is idle, pull the two shielding plates 61 to the front of plug 4 and push them closer together. The two shielding plates 61 slide outside the slider 63, and the two magnets 67 approach and attract each other, thus connecting the two shielding plates 61 to shield the surface of plug 4 and prevent stones from getting stuck between the two conductive posts 7. When charging, separate the two shielding plates 61 and move them away from the front of plug 4. Under the pull of the fourth spring 66, the shielding plates 61 are moved to both sides of the handle 1. The two shielding plates 61 will not obstruct the operation of plug 4.

[0055] Instructions for use: When the plug 4 is inserted into the socket housing 21, the hook 52 moves towards the fixed frame 24. The bevel of the hook 52 contacts one side of the metal ring 54. The hook 52 slides on the bevel of the metal ring 54 and slides downward on the outside of the fixed rod 51. As the hook 52 continues to move closer to the fixed frame 24, the hook 52 moves completely below the metal ring 54. The top of the hook 52 slides below the metal ring 54. Under the elastic force of the first spring 53, the hook 52 is pushed upward, so that the hook 52 is locked inside the metal ring 54. This ensures that the plug 4 and the socket housing 21 are sufficiently stable when plugged in.

[0056] When the plug 4 is pulled out of the socket housing 21, press the two pressing plates 551 with your thumb and forefinger. The two pressing plates 551 move closer to each other, which drives the two pressing rods 553 to move into the cavity 558. The pressing rods 553 push the first telescopic rod 557 to move inside the top rod 554. The two top rods 554 push the push plate 555 to apply a pushing force to the surface of the fixing block 23. The forces are mutual, so a pushing force is applied to the plug 4 in a direction away from the fixing block 23. Combined with the manual pulling force, the plug 4 can be easily pulled out of the socket housing 21 without constantly shaking the plug 4 to reduce friction.

[0057] Pressing the two pressing plates 551 brings them closer together. When the pressing plates 551 move downwards, they compress the third spring 5594. The third spring 5594, through the second limiting plate 5592, compresses the hook 52. At this time, the deformation force of the third spring 5594 is greater than that of the first spring 53. Therefore, the second limiting plate 5592 pushes the hook 52 to slide downwards on the outer surface of the fixing rod 51, causing the hook 52 to disengage from the inside of the metal retaining ring 54. At the same time, when the pressing plates 551 move the pressing rod 553, in order to avoid generating a synchronous pushing force on the push plate 555, the hook 52 may not be completely removed from the metal retaining ring. When the ring 54 gets stuck inside, the pressing rod 553 pushes the first telescopic rod 557 to slide a certain distance inside the top rod 554 when the pressing plate 551 moves. It does not exert any force on the top rod 554. When the hook 52 is completely removed from the inside of the metal ring 54, the hook 52 stops moving and the pressing plate 551 continues to move. At this time, the third spring 5594 is compressed to ensure the normal movement of the pressing plate 551. The first telescopic rod 557 moves to the very end inside the top rod 554 through the transmission. At this time, a force is generated on the push plate 555, so that the plug 4 can be pulled out from the inside of the socket housing 21 with less effort.

[0058] When plug 4 is idle, pull the two shielding plates 61 to the front end of plug 4, and then push the two shielding plates 61 closer to each other. The two shielding plates 61 slide outside the slider 63, and the two magnets 67 approach each other and attract and fix them, so that the two shielding plates 61 can be connected and shield the surface of plug 4 to prevent stones from getting stuck between the two conductive posts 7. When charging, separate the two shielding plates 61 and move them away from the front end of plug 4. Under the pull of the fourth spring 66, the shielding plates 61 are driven to both sides of the handle 1. The two shielding plates 61 will not obstruct the operation of plug 4.

[0059] The above description is merely a preferred embodiment of the present invention; however, the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and its improved concepts, should be covered within the scope of protection of the present invention.
