Description

Technical Field

[0001] This utility model relates to a charging head, specifically a press-and-release charging head structure. Background Technology

[0002] A charging adapter is mostly used to charge electronic devices such as smartphones and tablets. It is usually used in conjunction with a power cord to convert the AC power from the socket into low-voltage electricity suitable for electronic devices.

[0003] To ensure a stable connection when plugged into the socket and to prevent the charger from falling due to gravity or the pulling of the power cord, the electrodes of the charger are specially designed so that the charger can be firmly positioned on the socket after the electrodes are fully inserted.

[0004] Although it can be securely positioned on the socket, a certain amount of force is required to unplug the charging head. If the connection between the socket and the wall is not strong enough, the socket may be pulled out along with the wall and partially detached.

[0005] To overcome the above problems, existing technologies, such as the Chinese utility model patent with application number 202121133203.X entitled "Safe and Easy-to-Unplug Charging Head", disclose the following solution: "Safe and easy-to-unplug charging head, including a plastic shell, with a structural chamber built inside the plastic shell, and an assist mechanism provided inside the structural chamber; the assist mechanism has a rod-shaped ejector part, and a top outlet is opened on the plug-in surface for the ejector part to move and cooperate; one end of the ejector part is configured as a pivot end pivotally connected to the top outlet side; the assist mechanism also has a rod-shaped connecting part, one end of the connecting part is rigidly connected to the pivot end of the ejector part, and the other end of the connecting part extends into the structural chamber relative to the plug-in surface and forms a key-shaped pushing part at the end; an operation port for the pushing part to be exposed is opened on the plastic shell."

[0006] In the above scheme, when the pushing part is pushed towards the ejecting part, the ejecting part flips along the pivot axis to the outside of the plug surface, causing the ejecting end to be higher than the plug surface. This forces the plug surface to actively lift off the outer shell of the mains socket, thereby releasing the tight fit between the plug electrodes and the mains socket, so as to unplug the charging head.

[0007] While the above solution allows the charging head to be unplugged, the ejector part of the assist mechanism can easily cause squeezing damage to the plastic socket when rigidly supporting it for a long time, and also damages the aesthetics of the socket surface. Utility Model Content

[0008] The purpose of this utility model is:

[0009] A press-and-release charging head structure is designed. The structure of the charging head is improved by adding a flip lever. When it is necessary to remove the charging head, the flip lever is pressed to assist in the removal of the charging head. This optimizes the force applied to the socket, reduces wear on the socket surface, and reduces squeezing damage to the socket.

[0010] To achieve the above objectives, the present invention provides the following technical solution:

[0011] A press-and-release charging head structure includes a charging head body, a receiving groove, a flip lever, and a spring. The receiving groove is located on the side of the charging head body and is arranged symmetrically with respect to the electrodes of the charging head body. The receiving groove is connected to the end face of the charging head body where the electrodes are located and the side face of the charging head body. The flip lever is flip-mounted in the receiving groove and includes a pressing rod, a pushing rod, and a roller. The pressing rod and the pushing rod are at an angle. The roller is located at the end of the pushing rod facing the electrodes and is arranged symmetrically with respect to the pushing rod. The spring is located in the receiving groove and is connected to the flip lever.

[0012] Furthermore, both the pressing rod and the ejecting rod are elongated rod-shaped structures. The pressing rod is located near the side of the charging head body, and the ejecting rod is located near the end face of the charging head body.

[0013] Furthermore, the included angle between the pressing rod and the ejecting rod is 90-145°; and / or, the length of the pressing rod is greater than the length of the ejecting rod.

[0014] Furthermore, a pivot is provided between the pressing rod and the ejecting rod, and the pivot is rotatably connected to the inside of the receiving groove.

[0015] Furthermore, the roller is cylindrical and its axle is parallel to the shaft of rotation; the outer periphery of the roller is covered with a soft rubber layer; the roller can be housed in a groove on the charging head body, and the groove is connected to the receiving groove.

[0016] Furthermore, the surface of the pressing rod is provided with a groove, and the groove is provided with anti-slip texture.

[0017] Furthermore, the spring is a helical spring, and the spring is located between the bottom wall of the receiving groove and the pressing rod, and the spring is in a compressed state.

[0018] The beneficial effects of this utility model are as follows:

[0019] A press-and-release charging head structure is proposed, which improves the structure of the charging head by adding a flip lever. When it is necessary to remove the charging head, the finger presses the flip lever on the side of the charging head body, the flip lever flips, and the roller presses against the socket. The roller can achieve rolling friction, thereby assisting in the removal of the charging head. This optimizes the force applied to the socket. Compared with the sliding friction of rigid support, it can significantly reduce the wear on the socket surface, thereby helping to reduce the squeezing damage to the socket structure and ensuring the surface aesthetics of the socket.

[0026] To make the objectives, technical solutions, and advantages of this utility model clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the utility model and are not intended to limit the scope of the utility model.

[0027] refer to Figures 1 to 4 A press-and-release charging head structure includes a charging head body 1, a receiving slot 4, a flip lever 5, and a spring 6; the charging head body 1 has an approximately cuboid structure, and a slot 3 is provided at the end away from the electrode 2, which can be a USB slot or a type-C slot.

[0028] The receiving slot 4 is located on the side of the charging head body 1, and the receiving slot 4 is arranged symmetrically with respect to the electrode 2 of the charging head body 91; the receiving slot 4 is used to accommodate the flip lever 5, and there are two receiving slots 4.

[0029] The receiving groove 4 is connected to the end face of the charging head body 1 where the electrode 2 is located and the side face of the charging head body 1, respectively, thus providing sufficient space for the flipping action of the flipping lever 5.

[0030] The flip lever 5 is flip-mounted within the receiving groove 4. The flip lever 5 can be flipped relative to the charging head body 1 when pinched by fingers, thus supporting the socket and facilitating the removal of the charging head. The flip lever 5 includes a pressing rod 51, an ejecting rod 52, and a roller 55. The pressing rod 51 and the ejecting rod 52 are at an angle. When the hand presses or pinches the pressing rod 51, it will cause the ejecting rod 52 to flip.

[0031] The roller 55 is located at the end of the ejector rod 52 facing the electrode 2, and the roller 55 is arranged symmetrically with respect to the ejector rod 52; the roller 55 can rotate relative to the ejector rod 52 and roll along the surface of the socket.

[0032] Spring 6 is located in receiving groove 4 and connected to flip lever 5. Spring 6 is used to realize the automatic reset of flip lever 5.

[0033] Both the pressing rod 51 and the ejecting rod 52 are long and thin rod-shaped structures. The pressing rod 51 is located near the side of the charging head body 1, making it easy to press by pinching with your fingers; the ejecting rod 52 is located near the end face of the charging head body 1, so that the ejecting rod 52 is close to the socket.

[0034] The included angle between the pressing rod 51 and the ejecting rod 52 is 90-145°; and / or, the length of the pressing rod 51 is greater than the length of the ejecting rod 52, that is, the power arm is greater than the resistance arm. According to the lever principle, this can achieve a labor-saving effect and facilitate the smooth removal of the charging head body 1.

[0035] A rotating shaft 53 is provided between the pressing rod 51 and the ejecting rod 52. The rotating shaft 53 is rotatably connected to the inside of the receiving groove 4 and serves as the rotating shaft of the flipping lever 5.

[0036] The roller 55 is cylindrical and its axle is parallel to the rotating shaft 53. The roller 55 is rotatably connected to the ejector rod 52 through a bearing. The roller 55 is covered with a soft rubber layer, which is made of rubber or silicone and has a soft texture and strong anti-slip properties.

[0037] The roller 55 can be housed in the groove 41 on the charging head body 1. The groove 41 is connected to the receiving groove 4 to avoid structural interference.

[0038] The surface of the pressing rod 51 is provided with a groove, which is used to make it easier for the fingers to find the pressing position and pinch it. The groove is provided with anti-slip texture 54, which is a raised texture, and is used to prevent slipping.

[0039] Spring 6 is a helical spring, and spring 6 is located between the bottom wall of receiving groove 4 and pressing rod 51. Spring 6 is in a compressed state and is used to apply a continuous elastic force to pressing rod 51 so as to achieve self-reset after releasing flip lever 5.

[0040] The working principle of this utility model is as follows:

[0041] When you need to use the charging head, hold the top and bottom sides of the charging head body 1 with your fingers and insert the plug 2 of the charging head body 1 into the socket on the socket until it is fully inserted.

[0042] Under the elastic support of the spring 6, the pressing rod 51 moves away from the bottom wall of the receiving groove 4, the ejecting rod 52 retracts into the receiving groove 4, and the roller 55 retracts into the wheel groove 41. It will not protrude from the front side of the charging head body 1, so it will not cause structural interference to the contact and cooperation between the charging head body 1 and the socket.

[0043] When it is necessary to pull out the charging head body 1, the thumb and index or middle finger of the hand pinch the pressing rods 51 of the two flip levers 5 on both sides of the charging head body 1, specifically pinching the anti-slip texture 54 in the groove. Then pinch it tightly towards the middle of the charging head body 1. At this time, the pressing rods 51 overcome the elastic force of the spring 6 and flip towards the charging head body 1, driving the ejector rod 52 to flip outward relative to the receiving groove 4.

[0044] During the flipping process, the roller 55 at the end of the ejector rod 52 moves out of the wheel groove 41, and the soft rubber layer around the roller 55 presses against the socket. Since the soft rubber layer is soft and can undergo elastic deformation, it can avoid rigidly supporting the socket to a certain extent.

[0045] Since the rollers 55 on the two flip levers 5 support the socket at the same time, they will give the charging head body 1 a reaction force away from the socket.

[0046] Continue to squeeze the flip lever 5, and the pressing rod 51 will continue to drive the ejector rod 52 to flip. The roller 55 can roll on the surface of the socket, thereby avoiding scratches on the socket surface to a certain extent. The roller 55 moves out of the groove 41, and the ejector rod 52 provides assistance in pulling the charging head body 1 out of the socket. Thus, the force of squeezing the charging head body 1 can be used to assist in pulling out the charging head body 1.

[0047] The above embodiments are used to further illustrate the present invention, but do not limit the present invention to these specific embodiments. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be understood as being within the protection scope of the present invention.
