Description

Technical Field

[0001] The present invention generally relates to the field of charging battery sockets, and in particular to a charging battery socket. Background Art

[0002] With the development of electric energy, the popularity of electric vehicles is increasing, and there are more and more scenarios for using rechargeable batteries. Therefore, it is necessary to improve the reliability and convenience of rechargeable battery sockets. However, the current rechargeable battery sockets cannot meet the requirements of waterproof and dustproof. The surface of the plug connector is prone to accumulation and dust, and it is easy to wear when plugging and unplugging, which reduces the service life of the socket. The socket has no guide structure, or the guide structure is poor. The rechargeable battery docking socket requires manual adjustment of the battery position, which is inconvenient, inefficient and harmful to the connector. Summary of the invention

[0003] In view of the above-mentioned defects or deficiencies in the prior art, it is desired to provide a charging battery socket structure that is waterproof, dustproof and has a guiding structure.

[0004] In the first aspect, in order to make the charging battery socket waterproof and dustproof, the technical solution adopted by the present invention is to design a charging battery socket structure, including: an upper cover, a base, and a cover plate. A boss is provided on the inner side of the flip cover, and the boss cooperates with the opening of the base. A silicone wire sleeve is provided at the wire outlet of the base wire.

[0005] As a preference, the flip cover plate adopts a two-color injection molding process, and the structures other than the boss, such as the bottom plate and the shaft, are made of hard plastic material to ensure the strength of the shaft and the rigidity of the flip cover plate as a whole. The boss is made of soft plastic material, and the outer side of the boss is interference-fitted with the inner side of the opening of the upper cover connector.

[0006] Preferably, the upper cover and the base can be integrally formed.

[0007] Preferably, the interior of the boss is a cavity structure, and except for the edge where the rotating shaft is located, the other three edges of the flip cover plate have raised side wall structures, and a groove is formed between the side wall and the boss.

[0008] Preferably, the flip cover plate is fixed to the upper cover by a retaining spring pin and a retaining spring and can rotate freely around the retaining spring pin, thereby realizing the functions of opening when in use and closing when idle.

[0009] Preferably, a clamping shaft is arranged around the side wall of the flip cover plate, and a clamping shaft hole is arranged around the base, and the clamping shaft hole is a semi-closed hole with rounded corners at the opening.

[0010] Preferably, the upper cover and the bottom shell form an access port for the plug and the signal line on the back of the socket, and the grooves and the grooves form an inner cavity for containing and compressing the waterproof ring, so as to realize the waterproof function of the back port. The step at the joint surface of the base is contained in the inner sink of the upper cover, and the groove in the inner sink of the upper cover and the groove of the step at the joint surface of the base form an inner cavity for containing and compressing the silicone wire sleeve.

[0011] In the second aspect, in order to enable the rechargeable battery socket to automatically correct its position when the battery is inserted, the technical solution adopted by the present invention is to design a rechargeable battery socket structure, including an upper cover and a base. The upper cover has a first guide structure, and the base has a second guide structure, and the first guide structure and the second guide structure are nested or contained with each other.

[0012] The first guide structure includes an inclined guide surface, which cooperates with a straight guide surface below that runs through the height direction of the socket.

[0013] Among them, the inner side surface of the guide structure of the upper cover is contained in the outer side surface of the guide structure of the base. The inclined guide surface at the top of the guide structure has a gentle slope and a sufficient slope length. Combined with the straight guide surface below that runs through the height direction of the socket, it can very effectively adjust the insertion posture of the charging battery and ensure the smooth connection between the charging battery connector and the socket connector.

[0014] Preferably, the four grooves with through holes after the upper cover and the base are assembled are structures for mounting screws.

[0015] The present invention has the following beneficial effects: it can ensure that water, dew, sand and dust cannot enter from the connector opening and ensure that the entire socket meets the IP45 double protection standard; it can automatically correct the position when the battery is inserted, improve efficiency, and avoid damage to the connector. The design of the boss can make the internal soft glue and the connector fit tightly and in place. The characteristic of the soft glue that is easily compressed and deformed realizes the waterproof and dustproof function at the connector opening. Because rechargeable batteries are often heavy, the above-mentioned containment structure helps to improve the strength and rigidity of the guide structure, and prevent the guide structure from being damaged or deformed and failing when plugging and unplugging the rechargeable battery. The groove allows the socket to be installed in various occasions. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] The present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It is to be understood that the specific embodiments described herein are only used to explain the relevant invention, rather than to limit the invention. It is also necessary to explain that, for ease of description, only the parts related to the invention are shown in the accompanying drawings.

[0025] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0026] Figure 1 and Figure 3 A rechargeable battery socket is shown, which is suitable for connecting to a rechargeable battery. The rechargeable battery socket includes an upper cover 100, a base 200, a cover plate 300, a connector plate 400, a waterproof ring 500, a retaining ring 600 and a retaining ring pin 700.

[0027] See Figure 2 As shown, after the upper cover 100 of the charging battery socket is assembled with the base 200, four grooves 140 with through holes are formed, which are structures for mounting screws. With this structure, the socket can be installed in various occasions for use.

[0028] See also Figure 1 and Figure 2 It can be seen that when the cover 300 is in the open position (see Figure 1 ), the rechargeable battery socket can be matched with the rechargeable battery, when the cover 300 is in the closed position (see Figure 2 ), the cover plate 300 can prevent water and dust from entering the interior of the charging battery socket.

[0029] Figure 4 The charging battery socket upper cover 100 is shown. Figure 5The rechargeable battery socket base 200 is shown, wherein the upper cover 100 is provided with a first guide structure 110, and the base 200 is provided with a second guide structure 210. The inner side 111 of the first guide structure 110 is contained on the outer side 211 of the second guide structure 210 of the base 200. The guide structure is used to guide the rechargeable battery to align when the rechargeable battery and the rechargeable battery socket cooperate with each other. The main advantage of the above-mentioned mutually contained structure is that it helps to improve the strength and rigidity of the guide structure, because the rechargeable battery is often heavy, so it can prevent the guide structure from being damaged or deformed and failed when plugging and unplugging the rechargeable battery.

[0030] Preferably, an inclined guide surface 112 is provided at the top of the first guide structure. The inclined guide surface 112 has a gentle slope and a sufficient slope length, and cooperates with the straight guide surface 113 below that runs through the height direction of the socket. The main function is to facilitate the adjustment of the insertion posture of the rechargeable battery and ensure the smooth connection between the rechargeable battery connector and the socket connector. The step 220 at the joint surface of the base 200 is contained in the inner sink 120 of the upper cover 100, and has two main functions: ① limiting the relative movement of the upper cover and the base; ② preventing water from entering the inner side of the socket. The upper cover 100 and the base 200 form an access port for the plug and the signal line on the back of the socket, and the groove 130 and the groove 230 form an inner cavity for containing and compressing the waterproof ring 500 to realize the waterproof function of the back port, wherein the waterproof ring 500 can be a silicone wire sleeve or rubber or other waterproof materials. The waterproof ring includes a signal line outlet and a power connector port, and the waterproof ring is interference-fitted in the cavity formed by the groove 130 and the groove 230. The four grooves 140 with through holes after the upper cover 100 and the base 200 are assembled are structures for mounting screws. With this structure, the socket can be installed in various occasions for use, and the first guide structure and the second guide structure cooperate to form a structure in which an inclined guide surface and a straight guide surface are transitionally connected.

[0031] Read also Figure 2 and Figure 3 The outlet is provided on one side of the housing, and half of the groove is provided on the upper cover 100 and the base 200, so that when the electrical components are installed inside the housing, the power connector 430 can be limited to the outlet formed by the groove. Preferably, the opening direction of the first guide structure 110 and the second guide structure 120 is perpendicular to the direction of the outlet. This vertical position relationship setting allows the housing disassembly and installation direction to be no longer in the same straight line with the power cord plugging and unplugging force direction when the power connector 430 is plugged in or unplugged, thereby effectively ensuring the structural stability of the upper cover and the base, and extending the service life of the socket of the present application.

[0032] Figure 6The cover plate 300 of the charging battery socket is shown, wherein the cover plate 300 is fixed to the upper cover 100 through the snap spring pin 700 and the snap spring 600 and can rotate freely around the snap spring pin 700 or the upper cover 100, thereby realizing the functions of opening when in use and closing when idle. The cover plate can also be rotated and matched on the upper cover in other ways.

[0033] The cover plate 300 is provided with a boss 330, and the boss 330 is matched with the opening 150 of the upper cover 100. The boss 330 includes an elastic body, and is used for interference fit with the opening 150 of the upper cover 100. The opening 150 is used to receive the electrode of the battery (not shown). When the cover plate 300 is closed, it can be closely matched with the upper cover 100 to achieve a waterproof effect.

[0034] The cover plate 300 also includes a bottom plate 310, and the boss 330 protrudes from the bottom plate 310, and the rigidity of the bottom plate 310 is greater than that of the boss 330. The cover plate 300 can be made of a two-color injection molding process. In addition to the boss 330, the structures such as the bottom plate 310 and the shaft 320 are made of hard plastic material. The hard plastic material is used to ensure the strength of the shaft 320 and the rigidity of the cover plate 300 as a whole. The boss 330 is made of soft plastic material, and the outer side surface 331 of the boss is interference-fitted with the inner side surface 151 of the connector opening of the upper cover 100 in a whole circle. The main function is to use the characteristics of the soft plastic that is easy to compress and deform to achieve the waterproof and dustproof function at the opening 150. The inside of the boss 330 is a cavity structure, and its main function is to avoid the interference between the internal soft plastic and the connector board 400 when it is buckled in the connector opening 150, resulting in problems such as inadequate buckling and loose buckling. The cover plate 300 has a raised side wall 340 on the other three edges except the side where the rotating shaft 320 is located, and a groove 360 ​​is formed between the side wall 340 and the boss 330. When the cover plate 300 is closed, the opening 150 of the upper cover 100 is contained in the groove 360. Such a structure can prevent water, dust and other debris from directly contacting the opening 150 of the upper cover 100, and can make the upper cover 100 and the cover plate 300 more tightly and in place when they are matched.

[0035] Figure 7The connector board 400 of the rechargeable battery socket is shown, wherein the three sides of the connector 410 are in contact with the main support surface 181 of the upper cover connector support platform 180 and the groove side 131, so that the external force received during the plugging and unplugging of the rechargeable battery will not act entirely on the bottom pins. The PCB board 440 is fixed in the base PCB card slot 250, and the card slot 250 limits the PCB board 440 to 4 degrees of freedom in the horizontal direction and 1 degree of freedom in the vertical direction. The main functions of the signal line 420 are: ① to transmit the status of the rechargeable battery; ② to help the system realize real-time monitoring of the rechargeable battery. A waterproof ring 500 is arranged between the connector board 400 and the upper cover 100 and the base 200. The main function of the waterproof ring 500 is to realize the waterproof function of the signal line 420 and the power connector 430.

[0036] The cover plate 300 has two usage states, which are described as follows:

[0037] ① When the socket is in use, the cover 300 is opened, and the card shaft 350 is buckled into the card shaft hole 240 of the base 200. The card shaft hole 240 is a semi-closed hole, and the card shaft 350 buckled therein can only be disengaged under the action of a certain magnitude of external force. The main function of the entrance fillet of the card shaft hole 240 is to prevent the card shaft 350 from being damaged, which is conducive to the insertion and disengagement of the card shaft 350. The reason for fixing the cover 300 in the open state is: considering the scenario when the socket of the present application is applied to movable products (such as drones, unmanned vehicles, etc.), it is possible to avoid collision of the cover 300 due to the movement of the product.

[0038] ② When the socket is in an idle state, flip the cover plate 300 to a state where the inner surface 311 of the bottom plate fits with the connector opening surface 160. After buckling, the groove 360 ​​of the cover plate 300 contains the connector opening surface 160 of the upper cover 100, and the groove 170 of the upper cover 100 contains the side wall 340 of the cover plate 300. The double-containing structure forms the first protective barrier for the plug. The boss 330 cooperates with the connector opening 150 to form the second protective barrier. The double barrier can make the socket more waterproof and dustproof.

[0039] The above description is only a preferred embodiment of the present application and an explanation of the technical principles used. Those skilled in the art should understand that the scope of the invention involved in the present application is not limited to the technical solution formed by a specific combination of the above technical features, but should also cover other technical solutions formed by any combination of the above technical features or their equivalent features without departing from the inventive concept. For example, the above features are replaced with (but not limited to) technical features with similar functions disclosed in the present application.
