Abstract
Description
Technical Field
[0001] This utility model relates to the field of electrical connections, and in particular to a charging interface protection module for anti-icing bonding and a charging socket using the same. Background Technology
[0002] The charging ports of new energy charging equipment (such as charging sockets) generally need to be equipped with dust covers for protection. Side-flip dust covers are a common type. After the side-flip dust cover seals the charging interface, it needs to be locked with a locking device (such as a latch). Its drawback is that the contact surfaces of the locking device and the dust cover are opposite to each other, resulting in a large contact area. When the equipment is in a low-temperature environment for a long time, ice will form between the locking device and the dust cover. The ice formation will increase the friction or adhesion, making it difficult to open the dust cover. Utility Model Content
[0003] To address one or more of the aforementioned problems, this utility model provides a charging interface protection module for preventing icing and bonding, and a charging socket using the same.
[0004] According to one aspect of the present invention, the anti-icing adhesive charging interface protection module includes: a panel, a protective cover, an anti-icing lock, and a first damping spring.
[0005] The panel is fixedly connected to the front of the socket body, and a charging interface is provided in the middle of the panel;
[0006] One end of the protective cover is rotatably connected to the edge of the charging interface via a first rotating shaft, and the upper surface of the other end of the protective cover is provided with multiple recessed locking grooves.
[0007] The lower end of the anti-icing lock is rotatably connected to the other edge of the charging interface via a second rotating shaft. The upper inner side of the anti-icing lock is integrally provided with multiple locking blocks that cooperate with the locking groove. The upper end of the locking block is provided with a guide surface and the lower end is provided with a toothed contact end.
[0008] The first damping spring is located between the inner end of the anti-icing lock and the panel. In its natural state, the damping force of the first damping spring keeps the anti-icing lock vertical.
[0009] When an external force is applied, the protective cover rotates to the guide surface. The protective cover can push the anti-icing lock to rotate outward and slide along the guide surface to the bottom of the lock block. Then, the anti-icing lock is reset under the action of the first damping spring, and the toothed contact end presses against the locking groove, thereby making the protective cover tightly close the charging interface.
[0010] In some implementations, the upper inner side of the anti-icing lock body is integrally connected to multiple lock blocks, and the lower inner side of the lock block is provided with an upwardly concave toothed groove and the lower outer side forms a toothed contact end.
[0011] In some embodiments, the lower end of the toothed contact is provided with a plurality of pressing feet at equal intervals, and a clearance groove is formed between adjacent pressing feet.
[0012] In some embodiments, the guide surface is an arcuate surface extending from the upper outer side to the lower inner side, the toothed groove is an arcuate groove, and the inner surface of the toothed contact tip is an arcuate surface extending from the upper outer side to the lower inner side.
[0013] In some implementations, the upper surface of the lock body is integrally formed with several longitudinal protrusions at equal intervals.
[0014] In some embodiments, the inner end of the U-shaped groove of the locking groove is provided with a recessed rectangular fixing groove, and the locking groove and the locking block, the fixing groove and the pressing foot are positioned opposite each other and their sizes match; when the protective cover rotates to close and fit the charging interface, the toothed contact enters the U-shaped groove and the pressing foot presses and fits the fixing groove.
[0015] In some embodiments, a second damping spring is also included, which is disposed between the connection of the protective cover and the panel. In its natural state, the damping force of the second damping spring causes the protective cover to fold outward and stand upright.
[0016] In some embodiments, the hinge supports at both ends of the charging interface edge are rotatably connected to the first rotating shaft and the second rotating shaft, respectively;
[0017] The lower end of the lock body is provided with a C-shaped groove with a lower opening and fixed end blocks are formed on both sides. The middle section of the second rotating shaft is interference-fitted with the two fixed end blocks and passes through the C-shaped groove. The first damping spring is located in the C-shaped groove.
[0018] The connecting part at one end of the protective cover is provided with an open receiving groove. The middle section of the first rotating shaft is interference-fitted to the two end shaft holes of the connecting part and passes through the receiving groove. The second damping spring is located in the receiving groove and is sleeved on the first rotating shaft.
[0019] In some implementations, both the first damping spring and the second damping spring are torsion springs;
[0020] The first and second rotating shafts are pins, with one end plate positioned against the hinge support and the other end passing through another hinge support and fixed by a snap ring.
[0021] The advantages of this anti-icing bonding charging interface protection module are as follows: First, the protection module uses an anti-icing lock with toothed contacts and a locking groove on the protective cover to fit together, changing the original full-surface contact to point-line contact with toothed contacts, which greatly reduces the contact area. This results in a low probability of icing at the locking joint and a small icing area when the device is in a low-temperature environment, effectively preventing large-area icing that could cause the cover to stick and become impossible to open. Opening the cover is convenient and easy with low opening force, ensuring normal opening operations in low-temperature environments. Second, the protective cover has a grooved locking groove, which increases the engagement force between the anti-icing lock and the protective cover, and improves the locking force when the cover is closed. Third, the protection module is a modular structure, and the module and its components can be replaced individually, facilitating maintenance and assembly.
[0022] According to another aspect of this utility model, a charging socket includes a socket body and any of the aforementioned protective modules. The front end of the socket body is connected to the panel of the protective module, and the socket body's insertion hole enters the charging interface. Its advantages are: the charging socket has a high protection level, effectively preventing icing and sticking; it is convenient to open and close the cover; and it is simple and efficient to assemble.

[0035] The present invention will now be described in further detail with reference to the accompanying drawings. It should be noted that the terms "front," "rear," "left," "right," "up," and "down" used in the following description refer to the directions in the accompanying drawings, while the terms "inner" and "outer" refer to the directions toward or away from the geometric center of a specific component, respectively.
[0036] Figures 1 to 7 The diagram schematically illustrates an anti-icing adhesive charging interface protection module and a charging socket using the same, according to one embodiment of the present invention.
[0037] like Figures 1 to 6 As shown, the anti-icing bonding charging interface protection module includes: panel 1, protective cover 2, anti-icing lock 3, and first damping spring 4.
[0038] The panel 1 is fixedly connected to the front of the socket body 01 and has a charging interface 100 in the middle;
[0039] One end of the protective cover 2 is rotatably connected to one edge of the charging interface 100 via the first rotating shaft 5, and the other end of the protective cover 2 has multiple recessed locking grooves 21 on its upper surface.
[0040] The lower end of the anti-icing lock 3 is rotatably connected to the other edge of the charging interface 100 via the second rotating shaft 6. The upper inner side of the anti-icing lock 3 is integrally provided with multiple locking blocks 31 that cooperate with the locking groove 21. The upper end of the locking block 31 is provided with a guide surface 311 and the lower end is provided with a toothed contact end 312.
[0041] The first damping spring 4 is located between the inner end of the anti-icing lock 3 and the panel 1. In its natural state, the damping force of the first damping spring 4 keeps the anti-icing lock 3 vertical. Preferably, it also includes a second damping spring 7, which is located between the connecting part 20 of the protective cover 2 and the panel 1. In its natural state, the damping force of the second damping spring 7 keeps the protective cover 2 flipped outward and vertical. Its beneficial effect is that when the anti-icing lock 3 releases the protective cover 2, the protective cover 2 can automatically pop open under the action of the second damping spring 7. When the protective cover 2 is pressed down to the designated position, the anti-icing lock 3 automatically locks in place under the action of the first damping spring 4, which facilitates automated opening and closing of the cover, making opening and closing the cover simple and quick.
[0042] When an external force is applied, the protective cover 2 rotates to the guide surface 311. The protective cover 2 can push the anti-icing lock 3 to rotate outward and slide along the guide surface 311 to the lock block 31. Then, the anti-icing lock 3 resets under the action of the first damping spring 4, and the toothed contact end 312 presses against the locking groove 21, thereby making the protective cover 2 tightly close the charging interface 100.
[0043] The working principle of this anti-icing bonding charging interface protection module is as follows:
[0044] When opening the cover, apply external force to pry the anti-icing lock 3 open clockwise. The protective cover 2 can be opened manually or automatically. When the second damping spring 7 is provided, the elastic restoring force of the second damping spring 7 can make the protective cover 2 return to the vertical state, thereby opening the cover automatically.
[0045] During the closing operation, simply rotate the protective cover 2 clockwise. During the closing process, the protective cover 2 interferes with the guide surface 311 of the anti-icing lock 3. Rotation will push the anti-icing lock 3 open. After the protective cover 2 closes to the designated position and seals the charging interface 100, the interference between the protective cover 2 and the anti-icing lock 3 disappears. The anti-icing lock 3 automatically returns to its position under the elastic restoring force of the first damping spring 4, and the toothed contact end 312 of the anti-icing lock 3 presses against the locking groove 21 to fix and lock the protective cover 2.
[0046] The advantages of this anti-icing and bonding charging interface protection module are as follows: First, the protection module uses an anti-icing lock 3 with toothed contacts 312 and a locking groove 21 of the protective cover 2 to fit together, changing the original full-surface contact to a point-line contact of the toothed contacts 312, which greatly reduces the contact area. This results in a low probability of icing at the locking joint when the device is in a low-temperature environment, and a small icing area. This effectively prevents large-area icing from causing the cover to stick and become stuck, making it easy and convenient to open the cover with less force, ensuring normal opening operation in low-temperature environments. Second, the protective cover 2 has a locking groove 21 with a groove structure. This structure increases the hooking force between the anti-icing lock 3 and the protective cover 2, and improves the locking force when the protective cover 2 is closed. Third, the protection module is a modular structure, and the module can be replaced individually, as can the individual components within the module, facilitating maintenance and assembly.
[0047] Furthermore, the anti-icing lock 3 includes a flat lock body 30, with multiple lock blocks 31 integrally connected to the inner side of the upper end of the lock body 30. The inner side of the lower end face of each lock block 31 has an upwardly concave toothed groove 32, and the outer side of the lower end face forms a toothed contact end 312. The toothed groove 32 is preferably an arc-shaped groove, and the inner side of the toothed contact end 312 is preferably an arc-shaped surface extending from the upper outer edge to the lower inner edge. The beneficial effect is that this design greatly reduces the direct contact area between the toothed contact end 312 and the locking groove 21. In addition, the guide surface 311 is preferably an arc-shaped surface extending from the upper outer edge to the lower inner edge. The beneficial effect is that this design allows the protective cover 2 to push the anti-icing lock 3 smoothly and without jamming, ensuring stable and consistent operation over long-term use.
[0048] The protective cover 2 has multiple locking grooves 21 spaced longitudinally on its upper surface at equal intervals at the other end, and the anti-icing lock 3 has multiple locking blocks 31 integrally spaced longitudinally on its inner side at the upper end. The beneficial effect of this design is that it ensures a uniform distribution of contact positions, further optimizing the locking force.
[0049] Preferably, the lower end of the toothed contact 312 is provided with a plurality of pressing feet 33 at equal intervals, and a relief groove is formed between adjacent pressing feet 33 to reduce the contact area. The beneficial effect is that this arrangement optimizes line contact into point contact, further reduces the contact area, and has a better anti-icing and adhesion effect.
[0050] Furthermore, the upper surface of the lock body 30 is integrally formed with several longitudinal protrusions 35 at equal intervals, and the vertical cross-section of the longitudinal protrusions 35 is an arc shape. The beneficial effect is that the longitudinal protrusions 35 can increase the force when opening the anti-icing lock 3, avoid slipping due to excessive smoothness, and increase the convenience of closing the cover.
[0051] Furthermore, the inner end of the U-shaped groove 210 of the locking groove 21 is provided with a recessed rectangular fixing groove 211. The locking groove 21 and the locking block 31, the fixing groove 211 and the pressing foot 33 are positioned opposite each other and their sizes match. When the protective cover 2 rotates to close and fit the charging interface 100, the toothed contact end 312 enters the U-shaped groove 210 and the pressing foot 33 presses and fits the fixing groove 211. Its beneficial effect is that this setting can make the locking force large and the closure reliable.
[0052] Furthermore, a sealing gasket 23 is also interference-fitted into the sealing groove of the protective cover 2, and the sealing gasket 23 seals and fits snugly against the charging interface 100. The beneficial effect is that the sealing gasket 23 ensures that the charging interface 100 is sealed without gaps, with good closure effect and high protection effect.
[0053] Furthermore, two opposing hinge supports 101 are integrally formed at both ends of the edge of the charging interface 100, and the two hinge supports 101 are rotatably connected to the first rotating shaft 5 and the second rotating shaft 6 respectively.
[0054] The lower end of the lock body 30 is provided with a C-shaped groove 34 with a lower opening and fixed end blocks 36 are formed on both sides. The middle section of the second rotating shaft 6 is interference-fitted with the two fixed end blocks 36 and passes through the C-shaped groove 34. The first damping spring 4 is located in the C-shaped groove 34.
[0055] The connecting part 20 at one end of the protective cover 2 is provided with an open receiving groove 22. The middle section of the first rotating shaft 5 is interference-fitted into the shaft holes at both ends of the connecting part 20 and passes through the receiving groove 22. The second damping spring 7 is located in the receiving groove 22 and is sleeved on the first rotating shaft 5. Its beneficial effects are: the spring setting effectively reduces the size of the equipment, making it compact and easy to install.
[0056] Preferably, both the first damping spring 4 and the second damping spring 7 are torsion springs.
[0057] The spring body of the first damping spring 4 is sleeved on the second rotating shaft 6 and its two torsion arms respectively fix the lock body 30 and the panel 1.
[0058] The second damping spring 7 is sleeved on the first rotating shaft 5, and its two torsion arms are respectively fixed to the connecting part 20 and the panel 1. Its beneficial effect is that this setting can improve the elastic force and effectively realize automatic recovery operation.
[0059] Preferably, the first rotating shaft 5 and the second rotating shaft 6 are pins, with one end plate positioned against a hinge support 101 and the other end passing through another hinge support 101 and fixed by a snap ring 8. The advantages are: this arrangement has a simple structure and is easy to assemble.
[0060] like Figure 7 As shown, a charging socket includes a socket body 01 and any of the aforementioned protective modules 00. The front end of the outer shell 010 of the socket body 01 is threadedly connected to the panel 1 of the protective module 00. The socket hole 011 of the socket body 01 enters the charging interface 100. When not charging, the protective cover 2 closes the charging interface 100 to protect the socket hole 011. When charging, the protective cover 2 rotates to one side to expose the charging interface 100 and the socket hole 011 therein. The socket body 01 is a charging socket for new energy vehicles. Its advantages are: the charging socket has a high protection level, effectively avoids icing and sticking, is easy to open and close, and is simple and efficient to assemble.
[0061] The above descriptions are merely some embodiments of this utility model.
