Description

Technical Field

[0001] The utility model belongs to the technical field of battery charging, and particularly relates to a magnetic adsorption charging structure for an electric motorcycle battery. Background Art

[0002] To promote energy conservation, emission reduction and environmental protection, major cities are now advocating the use of electric transportation tools, such as electric buses, electric vehicles and electric motorcycles. Electric motorcycles are one of the most convenient electric transportation tools for personal travel. For easy charging, as disclosed in the storage box configuration of an electric motorcycle in Chinese Patent CN102039959B, the battery of an electric motorcycle is mostly vertically inserted into a battery box on the vehicle body, and its charging interface is set at the top of the battery. When charging, the cover plate or seat cushion covering the battery box is flipped open, and the battery is taken out or directly connected to the charging connector for charging.

[0003] Currently, most of the battery charging structures of electric motorcycles on the market adopt a three-pin plug-in male plug interface in a triangular shape. For example, the charging interface of an electric vehicle battery box disclosed in Chinese Patent CN202601950U and an improved electric vehicle charging interface structure disclosed in CN106099494A. The charging connector that matches the triangular charging interface has only one correct insertion direction, which is rather troublesome to use. A charging interface of an electric vehicle disclosed in Chinese Patent CN206163792U distributes the jacks on the charging interface in a centrosymmetric manner, enabling the charging connector to be inserted in either direction, reducing the usage difficulty. However, during the charging operation, the charging connector still needs to be aligned with the charging interface and inserted forcefully, which is not only laborious, but also likely to cause the plug-in fit to become loose due to wear and poor charging contact. Moreover, during charging, if the vehicle body or the battery accidentally moves, it is easy to damage the charging interface or the charging connector, and the reliability is poor.

DETAILED DESCRIPTION

[0025] In order to make the purpose, technical solution and advantages of the embodiments of the present utility model clearer, the technical solution in the embodiments of the present utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the present utility model.

[0026] Example:

[0027] See also Figure 1 and Figure 2, an electric motorcycle battery magnetic charging structure, comprising a battery 1 and a charging connector 2, wherein the battery 1 has a charging input surface on its outer wall, the charging input surface has a charging input contact 3, and a first magnetic member 4 is provided on the outer wall surface or inside of the battery 1 near the charging input contact 3; the charging connector 2 has a charging output surface, the charging output surface has a charging output contact 5 adapted to the charging input contact 3, and a second magnetic member (not shown in the figure) is provided on the surface or inside of the charging connector 2 near the charging output contact 5; both the first magnetic member 4 and the second magnetic member are magnetic and at least one of them is a magnet, and the charging connector 2 can be adsorbed on the battery 1 under the magnetic force of the first magnetic member 4 and the second magnetic member, and the charging output contact 5 is kept in contact and conduction with the charging input contact 3;

[0028] The charging input contact 3 and the charging input surface together form a charging interface corresponding to the charging connector 2, and the charging input contact 3 is electrically connected to the battery cell inside the battery 1; when the first magnetic attraction component 4 is a magnet (such as a magnet, a permanent magnet, an electromagnet), the second magnetic attraction component can be a magnet or a magnetic metal (such as an iron sheet); when the second magnetic attraction component is a magnet, the first magnetic attraction component 4 can be a magnet or a magnetic metal (it can be understood that when the second magnetic attraction component is a magnet, the outer wall portion of the battery with the charging point interface should be made of a non-magnetic material to avoid the charging connector 2 being magnetically attracted to the outer wall of the battery); when the first magnetic attraction component 4 and the second magnetic attraction component are both magnets, the magnetic polarity of the outward side of the first magnetic attraction component 4 should be opposite to the magnetic polarity of the outward side of the second magnetic attraction component; in addition, the magnetic force of the first magnetic attraction component 4 and the second magnetic attraction component should not be too large while satisfying the adsorption of the charging connector 2 so that the charging connector 2 can be easily removed after charging is completed.

[0029] The electric motorcycle battery magnetic charging structure of the utility model is provided with magnetic suction parts around the charging input contact 3 on the battery 1 and around the charging output contact 5 on the charging connector 2. When charging, after the charging output surface of the charging connector 2 is directly facing the charging input surface, the charging connector 2 can automatically move closer to the charging input surface under the magnetic force of the first magnetic suction part 4 and the second magnetic suction part, and finally be adsorbed on the battery 1, so that the charging output contact 5 is connected with the charging input contact 3, and the charging connector 2 is connected to the power grid to charge the battery 1. When implemented, the magnet is preferably a permanent magnet, and can also be an electromagnet when necessary. Before the charging connection is required, the electromagnet is controlled to be electrically magnetized, and the subsequent docking has the same use effect.

[0030] Compared with the current plug-in charging structure, the utility model not only does not need to use force to connect the charging connector 2 with the charging interface, which is more labor-saving, but the connection between the charging connector 2 and the charging interface mainly relies on magnetic force rather than plug-in matching surfaces, and there will be no loose matching and poor charging contact due to wear. The utility model can effectively solve the problem of laborious plug-in and inconvenient use of the current electric motorcycle charging structure, and achieves the effect of reducing the difficulty of charging operation and improving the user experience.

[0031] See also Figure 2 and Figure 3 In order to avoid misalignment between the charging output contact 5 and the charging input contact 3 when the charging connector 2 is adsorbed on the battery 1, resulting in failure of normal charging; the charging input surface is designed to be a concave surface, and the charging output surface is designed to be a convex surface that matches the charging input surface; or the charging input surface is a convex surface, and the charging output surface is designed to be a concave surface that matches the charging input surface; in this way, positioning is achieved through the concave and convex cooperation of the charging input surface and the charging output surface during docking, ensuring that the charging output contact 5 can be in direct contact with the charging input contact 3 after docking.

[0032] See also Figure 2 and Figure 3 In this embodiment, the charging input surface is designed to be a concave surface, the charging output surface is designed to be a convex surface adapted to the charging input surface, and the outer wall of the battery 1 where the charging input surface is located is non-magnetic; the first magnetic attraction member 4 is arranged inside the outer wall of the battery 1, and the second magnetic attraction member is arranged inside the charging connector 2; the first magnetic attraction member 4 is an annular structure surrounding the charging input contact 3, and the second magnetic attraction member is an annular structure surrounding the charging output contact 5; or there are multiple first magnetic attraction members 4 and they are evenly distributed around the charging input contact 3, and there are multiple second magnetic attraction members and they are evenly distributed around the charging output contact 5;

[0033] In this way, since the first magnetic attraction member 4 and the second magnetic attraction member are annular or circumferentially evenly distributed, when the charging output surface is completely opposite to the charging input surface, the first magnetic attraction member 4 and the second magnetic attraction member are also completely opposite to each other, which is the most stable state. Since the charging input surface is a concave surface, the charging connector 2 is close to or abuts against the outer wall surface of the battery 1, and its movement is not blocked; during charging, when the charging connector 2 is close to the battery 1 and the charging output surface is not completely opposite to the charging input surface, the two are close to each other so that the magnetic force reaches a certain intensity, and the charging connector 2 will be pulled by the magnetic force to move and automatically correct the deviation, so that the charging output surface is opposite to the charging input surface, and finally adsorbed together to achieve contact and conduction between the charging output contact 5 and the charging input contact 3;

[0034] It can be understood that when charging, you only need to hold the charging connector 2 so that the charging output surface is close to the charging input surface, or press it against the outer wall of the battery 1 close to the charging input surface, and then release the charging connector 2. The charging connector 2 will automatically be adsorbed back into place under the action of the magnetic force, so that the charging output contact 5 and the charging input contact 3 are in contact and conductive; when connecting the charging connector 2 to the charging interface, there is no need to ensure that the two are completely facing each other, which can effectively reduce the difficulty of the charging operation, especially in dim light conditions, which is conducive to improving the user experience.

[0035] See also Figure 2 and Figure 3There are multiple charging input contacts 3 and they are distributed symmetrically in the center, and there are multiple charging output contacts 5 and they are adapted to the distribution of the charging input contacts 3; in this way, the charging connector 2 can be close to the charging interface and can be docked, which is conducive to reducing the difficulty of use. When multiple contacts have docking order requirements, the orientation uniqueness of the magnetic connection can be limited by the necessary adaptation of the convex and concave shapes.

[0036] See also Figure 4 A rubber cover 6 covering the charging input surface and being removable is provided on the outer wall of the battery 1, and a third magnetic attraction member (not shown in the figure) having magnetic properties is embedded in the rubber cover 6, and at least one of the third magnetic attraction member and the first magnetic attraction member 4 is a magnet, and the inner side of the rubber cover 6 can maintain a sealed contact with the top surface of the boss 11 under the magnetic force of the third magnetic attraction member and the first magnetic attraction member 4; in this way, the rubber cover 6 is provided to cover and protect the charging interface, and the rubber cover 6 also adopts magnetic adsorption, which can avoid the loosening or even failure due to wear after a long time.

[0037] See also Figure 4 , one side of the rubber cover 6 has a connecting plate 7 extending on the outer wall of the battery 1, and the connecting plate 7 is connected to the outer wall of the battery 1 by a screw 8 passing through it. There is a wedge-shaped, easily bendable connecting portion 9 on the connecting plate 7 between the rubber cover 6 and the screw 8. When the rubber cover 6 is lifted up, the connecting plate 7 is folded at the connecting portion 9; in this embodiment, a strip groove 16 connected to the water guide groove 10 is also provided on the outer wall of the battery 1 to accommodate the connecting plate 7, so that the rubber cover 6 and the connecting plate 7 are both embedded in the outer wall of the battery 1, which is more beautiful. A threaded hole 17 is provided in the strip groove 16 for connecting the screw 8; in this way, the rubber cover 6 can be flipped and connected to the outer wall of the battery 1. When charging, the rubber cover 6 is lifted up to connect the charging connector 2. After the charging connector 2 is removed, the rubber cover 6 will flip toward the charging interface under its own elastic force and be sucked tightly under the action of magnetic force. There is no need to manually operate the cover, which makes the charging operation simpler and is conducive to improving the user experience.

[0038] See also Figure 1 and Figure 3The outer wall of the battery 1 has a water guide groove 10, and the bottom of the water guide groove 10 has a boss 11 lower than the outer wall surface of the battery 1. The bottom surface of the water guide groove 10 and the top surface of the boss 11 form the charging input surface, and the charging input contact 3 is located on the top surface of the boss 11; there is a gap between the boss 11 and the side wall of the water guide groove 10 and a drainage groove 12 surrounding the boss 11 is formed, and the drainage groove 12 has a leakage hole or a leakage gap 13 to drain the water entering the water guide groove 10 to play a waterproof role; the charging output surface A groove 14 is provided on the top surface of the boss 11, and the charging output contact 5 is located on the bottom surface of the groove 14; in this way, when water passes through the charging interface and enters the water guide groove 10, it will flow along the drainage groove 12 in time and be discharged through the leakage hole or leakage gap 13. The charging input contact 3 is arranged on the top surface of the boss 11 higher than the drainage groove 12, which can avoid short circuit or corrosion caused by contact with water; in this embodiment, the boss 11 has two levels, which are round and square respectively, and the groove 14 corresponds to it.

[0039] See also Figure 3 In this embodiment, in order to facilitate manufacturing and assembly, the boss 11 is designed to be a non-magnetic mounting block embedded in the bottom of the water channel 10, and the first magnetic attraction member 4 is embedded inside the mounting block.

[0040] See also Figure 1 and Figure 2 In order to prevent the charging connector 2 from being deflected relative to the charging interface due to the swing of the wire connected to the charging connector 2 or other small external forces after being adsorbed and docked at the charging interface, causing the charging output contact 5 to shift and disengage from the charging output contact 5, the outer contours of the charging input surface and the charging output surface or / and the outer contours of the boss 11 and the groove 14 are designed to be rectangular; in this way, the charging connector 2 will not deflect arbitrarily after being adsorbed, which is conducive to improving the reliability of the contact and conduction between the charging output contacts 5 and the charging output contacts 5, ensuring smooth charging.

[0041] See also Figure 3 In this embodiment, mounting holes are respectively provided on the charging output surface and the charging input surface, and elastic contact pins 15 are insulated in the mounting holes. The outer ends of the elastic contact pins 15 on the charging connector 2 extend out of the charging output surface to form the charging output contact 5, and the outer ends of the elastic contact pins 15 at the charging interface are lower than the charging input surface to form the charging input contact 3. When the charging connector 2 is adsorbed and docked on the charging interface, the part of the elastic contact pins 15 on the charging connector 2 extending out of the charging output surface falls into the corresponding mounting holes at the charging interface and abuts against the outer ends of the elastic contact pins 15 in the charging interface, so that the charging connector 2 is electrically connected to the charging interface. Every two elastic contact pins 15 abutting against each other are in a compressed state to ensure the stability of the abutment conduction, so that charging can proceed smoothly. In implementation, the elastic contact pins 15 on the charging connector 2 should be retractable, and the contact pins at the charging interface can also be fixed, and vice versa.

[0042] During implementation, the other end of the charging connector 2 is connected to the energy storage device. The energy storage device and the charging connector 2 can be mounted on the vehicle; or they can be separated from the vehicle. When necessary, the energy storage device can be hung on the vehicle body, such as the handlebars of a motorcycle, and the charging connector 2 can be magnetically attached to the battery 1 for charging and riding.

[0043] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit the technical solution. Ordinary technicians in this field should understand that those modifications or equivalent replacements of the technical solution of the utility model without departing from the purpose and scope of the technical solution of the utility model should be included in the scope of the claims of the utility model.
