Description

Technical Field

[0001] This invention relates to the field of battery charger technology, and in particular to a portable smart car battery charger with a waterproof connector structure. Background Technology

[0002] Car batteries are consumable parts. As the source of power for the car's electrical system, they are also an essential component for starting the car. After a period of use, the battery needs to be charged. The quality of the charger directly affects the battery's effectiveness. A high-quality charger should have advantages such as short charging time, minimal impact on battery life, and accurate full charge detection.

[0003] Some portable smart chargers have a quick-connect interface on the output side, where clips and ring terminals can be plugged in and out at any time. This interface usually achieves a safe and reliable quick connection by matching the rated current with the foolproof polarity, allowing users to switch between accessories such as alligator clips and ring terminals in seconds: it is convenient for short-term temporary charging, and it is also convenient to fix the ring terminal to the battery for a long time. When not in use, it can be used with a dustproof and waterproof cap to improve weather resistance.

[0004] For example, "CN120824879A" describes a portable smart car battery charger with a waterproof structure. This invention relates to the field of charger technology and includes a housing device. This portable smart car battery charger with a waterproof structure, through its housing design, encloses the charger in a shell, thus providing protection, reducing external water splashes and other disturbances, and improving equipment safety. Pads elevate the shell to reduce water immersion. Guide plates limit the device's sliding space, preventing component movement, improving stability during placement, and reducing mechanical wear between components, thereby extending their lifespan. The guide mechanism provides shock absorption and cushioning. A clamping mechanism presses the charger from both sides, contacting grooves on both sides of the charger to secure it, preventing any impact on subsequent operation efficiency and facilitating subsequent relocation.

[0005] However, in the existing technology, portable car smart battery chargers are often used in engine compartments, motorcycle exteriors and open-air environments. Existing sockets mostly rely on rubber dust caps, straight rubber boots or a single O-ring seal on the end face, with the plug and socket end face touching. However, such structures are prone to rain or spray entering the cavity, and short circuits are likely to occur when connected. At the same time, some solutions have the risk of conducting without sealing when partially inserted, making it difficult to work safely. Summary of the Invention

[0006] In view of the aforementioned existing problems, the present invention is proposed.

[0007] The purpose of this invention is to solve the problem that the waterproof performance of the plug of some portable car smart battery chargers is not very good in the prior art.

[0008] To solve the above-mentioned technical problems, the present invention provides the following technical solution:

[0009] On one hand, the present invention provides a portable intelligent car battery charger with a waterproof connector structure, comprising a charger body with a slot, a charging cable detachably electrically connected to the slot, a plug at one end of the charging cable engaging with the slot, a fixing seat on the side wall of the charger body, the slot being formed on the fixing seat and the side wall of the charger body, the end face of the plug engaging with the end face of the slot via a locking mechanism, a male plug being provided above the plug, a female plug being slidably provided in the fixing seat above the inner end of the slot, a waterproof sealing sleeve being rotatably provided on the outside of the plug, a connecting groove adapted to the male plug being provided on the waterproof sealing sleeve, an arc-shaped rail being provided on the outside of the waterproof sealing sleeve, a first sliding groove and a second sliding groove being provided below the plug at both ends of the waterproof sealing sleeve, and a slider being provided at the outer end of the slot to slide and adapt to the arc-shaped rail, the first sliding groove and the second sliding groove.

[0010] Furthermore, a side groove is provided on the outer side of the plug, the sealing and waterproof sleeve is rotatably disposed in the side groove, and the arc-shaped rail is located at the outer half of the sealing and waterproof sleeve;

[0011] By setting the arc-shaped rail at the outer half of the sealed waterproof sleeve, it can be ensured that each time the slider drives the arc-shaped rail to rotate, it rotates exactly 180 degrees, rotating the connecting groove located directly below to the top.

[0012] Furthermore, a first magnetic block and a second magnetic block are respectively provided at both ends of the arc-shaped rail, and a third magnetic block and a fourth magnetic block are respectively provided at the end of the first and second slides facing the arc-shaped rail. The third magnetic block and the first magnetic block are attracted to each other, and the fourth magnetic block and the second magnetic block are attracted to each other.

[0013] Through the mutual attraction between the magnetic blocks, when the sealing waterproof sleeve is rotated and the connecting groove is in the downward position, the first and third magnetic blocks attract each other, which can promote the connection between the first slide groove and the end face of the arc-shaped rail. This avoids the labor of workers frequently adjusting the position of the arc-shaped rail during installation. In addition, when the slider passes through the arc-shaped rail and connects to the second slide groove, the fourth magnetic block attracts the second magnetic block, ensuring that the arc-shaped rail and the port of the second slide groove remain connected. This prevents the slider from failing to enter the arc-shaped rail smoothly when pulled out, thus avoiding the problem of the plug failing to be pulled out.

[0014] Furthermore, the engaging mechanism includes an engaging block and an engaging groove. The engaging block is disposed on the end face of the plug, and the engaging groove is opened in the inner end of the slot. Assembly grooves are symmetrically opened on both sides of the engaging block. A limiting plate is rotatably disposed in the assembly groove at one end away from the plug. The limiting plate is assembled and connected to the assembly groove by a first spring. Limiting grooves adapted to the limiting plate are opened in the fixing seats on both sides of the engaging groove.

[0015] Once the locking block and locking groove are fully engaged, the limiting plate loses its limiting position and unfolds into the limiting groove under the push of the first spring, thus achieving positioning. At this point, the plug is installed in the slot.

[0016] Furthermore, a channel is provided inside the lower part of the plug, and multiple guide rollers are rotatably arranged in the channel. A steel wire rope is provided in the channel. One end of the steel wire rope is connected to two limiting plates respectively through a branch rope. The other end of the steel wire rope passes through the channel through the multiple guide rollers and extends to the lower part of the plug end face.

[0017] By pulling the outer end of the steel wire rope, the two limiting plates are tightened into the assembly groove, causing the limiting plates to completely disengage from the limiting groove. At this point, the plug can be easily pulled out of the slot.

[0018] Furthermore, a fixed plate and a sliding plate are provided below the end of the plug away from the locking mechanism. A handle is provided below the sliding plate. The sliding plate is slidably disposed below the plug. The fixed plate and the sliding plate are connected by a second spring. The end of the wire rope away from the locking mechanism is connected to the sliding plate.

[0019] Furthermore, a sealing groove is provided above the fixing base, and the female plug is slidably disposed in the sealing groove. The side wall of the sealing groove is connected to the female plug by a cylinder.

[0020] By extending the cylinder, the female connector moves downward until it is fully engaged with the male connector, thus achieving electrical connection.

[0021] Furthermore, a pressure sensor is provided in the limiting groove, and a microcontroller is provided on the charger body. The pressure sensor is electrically connected to the cylinder through the microcontroller.

[0022] Furthermore, a waterproof groove is provided on the outer side of the charger body located at the fixed base, the slot is located above the waterproof groove, and a waterproof plate is rotatably provided at the upper end of the waterproof groove via a coil spring;

[0023] The waterproof grooves and waterproof panels further prevent raindrops from entering the slots during rainy weather.

[0024] The beneficial effects of this invention are:

[0025] 1. This invention uses a sealed waterproof sleeve to protect the male plug portion when not in use, keeping it dry. During the engagement of the plug and slot, the sealed waterproof sleeve automatically rotates 180 degrees, moving its connecting groove upwards. This process takes place inside the slot, preventing rainwater from wetting the exposed male plug portion from the top down during the rotation of the sealed waterproof sleeve. Once the plug and slot are fully engaged, the female plug is automatically triggered to move downwards, engaging with the male plug and achieving electrical connection. The female plug is positioned above the slot, so even if rainwater enters the slot, it will not wet the female plug, ensuring the dryness of both the male and female plugs.

[0026] 2. By setting the arc-shaped rail at the outer half of the sealed waterproof sleeve, the present invention can ensure that each time the slider drives the arc-shaped rail to rotate, it rotates exactly 180 degrees, rotating the connecting groove located directly below to the top.

[0027] 3. When the sealing and waterproof sleeve is rotated so that the connecting groove is in the lower position, the first magnetic block and the third magnetic block attract each other, which can make the first slide groove and the end face of the arc-shaped rail connect. This avoids the labor of workers frequently adjusting the position of the arc-shaped rail during installation. In addition, when the slider passes through the arc-shaped rail and connects with the second slide groove, the fourth magnetic block and the second magnetic block attract each other, ensuring that the arc-shaped rail and the port of the second slide groove always remain connected. This avoids the problem of the slider not being able to smoothly enter the arc-shaped rail when pulling out, which would cause the plug to fail.

[0028] 4. This invention uses the engagement of the locking block and the locking groove to position the plug in the slot, ensuring that the male and female plugs are aligned. By moving the handle with a finger, the internal steel wire rope is moved, which in turn moves the limiting plate closer to the locking block, causing it to disengage from the limiting groove. At this point, the plug can be easily pulled out of the slot. Attached Figure Description

[0041] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0042] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and those skilled in the art can make similar extensions without departing from the spirit of the invention. Therefore, the invention is not limited to the specific embodiments disclosed below.

[0043] Secondly, as used herein, "an embodiment" or "embodiment" refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that is mutually exclusive with other embodiments.

[0044] Please see Figures 1-9 The present invention provides a technical solution: a portable car smart battery charger with a waterproof plug structure, including a charger body 2 with a slot 1, a charging cable 3 detachably electrically connected to the slot 1, and a plug 4 at one end of the charging cable 3 that engages with the slot 1.

[0045] The charger body 2 has a fixed base 5 on its side wall. The slot 1 is opened on the fixed base 5 and the side wall of the charger body 2. The end face of the plug 4 is engaged with the end face of the slot 1 through a locking mechanism. The plug 4 has a male plug 6 above it. The slot 1 has a female plug 7 that slides up and down inside the fixed base 5 above the inner end.

[0046] A sealing waterproof sleeve 8 is rotatably provided on the outside of the plug 4. A connecting groove 9 adapted to the male plug 6 is provided on the sealing waterproof sleeve 8. An arc-shaped rail 101 is provided on the outside of the sealing waterproof sleeve 8. A first sliding groove 102 and a second sliding groove 103 are respectively provided below the plug 4 at both ends of the sealing waterproof sleeve 8. A slider 104 is provided at the outer end of the slot 1 to slide and adapt to the arc-shaped rail 101, the first sliding groove 102 and the second sliding groove 103.

[0047] like Figures 1-9 As shown, a side groove 11 is provided on the outside of the plug 4, and the sealing waterproof sleeve 8 is rotatably disposed in the side groove 11. The arc-shaped rail 101 is located at the outer half of the sealing waterproof sleeve 8.

[0048] By setting the arc-shaped rail 101 at the outer half of the sealing waterproof sleeve 8, it can be ensured that each time the slider 104 drives the arc-shaped rail 101 to rotate, it rotates exactly 180 degrees, rotating the connecting groove 9 located directly below to directly above.

[0049] The arc-shaped rail 101 is provided with a first magnetic block 121 and a second magnetic block 122 at both ends. The first slide groove 102 and the second slide groove 103 are provided with a third magnetic block 123 and a fourth magnetic block 124 at one end facing the arc-shaped rail 101, respectively. The third magnetic block 123 and the first magnetic block 121 are attracted to each other, and the fourth magnetic block 124 and the second magnetic block 122 are attracted to each other.

[0050] Through the mutual attraction between the magnetic blocks, when the sealing waterproof sleeve 8 is rotated and the connecting groove 9 is in the lower position, when the first magnetic block 121 and the third magnetic block 123 attract each other, the first sliding groove 102 can be connected to the end face of the arc rail 101, avoiding the labor of workers to frequently adjust the position of the arc rail 101 during installation.

[0051] In addition, when the slider 104 passes through the arc-shaped rail 101 and connects with the second slide groove 103, the fourth magnetic block 124 and the second magnetic block 122 are mutually attracted to each other, ensuring that the arc-shaped rail 101 and the port of the second slide groove 103 are always connected, so as to avoid the problem that the slider 104 cannot smoothly enter the arc-shaped rail 101 when it is pulled out, causing the plug 4 to fail.

[0052] The engaging mechanism includes an engaging block 131 and an engaging groove 132. The engaging block 131 is disposed on the end face of the plug 4, and the engaging groove 132 is opened in the inner end of the slot 1. Assembly grooves 133 are symmetrically opened on both sides of the engaging block 131. A limiting plate 134 is rotatably provided in the assembly groove 133 away from the plug 4. The limiting plate 134 is assembled and connected to the assembly groove 133 by a first spring 135. The fixing seats 5 on both sides of the engaging groove 132 are provided with limiting grooves 136 that are adapted to the limiting plate 134.

[0053] In the initial state, the first spring 135 pushes the limiting plate 134 outward. When the engaging block 131 engages with the engaging groove 132, the limiting plates 134 on both sides are squeezed and contracted in the assembly groove 133. When the engaging block 131 and the engaging groove 132 are fully engaged, the limiting plate 134 loses its limiting position and unfolds into the limiting groove 136 under the pushing action of the first spring 135 to achieve positioning. At this time, the plug 4 is installed in the slot 1.

[0054] The plug 4 has a channel 141 located at the bottom inside. Multiple guide rollers 142 are rotatably arranged in the channel 141. A steel wire rope 143 is arranged in the channel 141. One end of the steel wire rope 143 is connected to two limit plates 134 respectively through a branch rope. The other end of the steel wire rope 143 passes through the channel 141 via multiple guide rollers 142 and extends to the bottom of the end face of the plug 4.

[0055] By pulling the outer end of the steel wire rope 143, the two limiting plates 134 are tightened into the assembly groove 133, causing the limiting plates 134 to completely disengage from the limiting groove 136. At this time, the plug 4 can be smoothly pulled out of the slot 1.

[0056] A fixed plate 151 and a sliding plate 152 are provided below the end of the plug 4 away from the locking mechanism. A handle 153 is provided below the sliding plate 152. The sliding plate 152 is slidably disposed below the plug 4. The fixed plate 151 and the sliding plate 152 are connected by a second spring 154. The end of the wire rope 143 away from the locking mechanism is connected to the sliding plate 152.

[0057] By flicking the handle 153 with your finger, you can pull the internal steel wire rope 143 to move, thereby moving the limit plate 134 closer to the locking block 131 and disengaging it from the limit groove 136. At this time, the plug 4 can be easily pulled out of the slot 1.

[0058] A sealing groove 161 is provided above the fixed base 5. The female plug 7 is slidably disposed in the sealing groove 161. The side wall of the sealing groove 161 is connected to the female plug 7 by a cylinder 162.

[0059] By driving the cylinder 162 to extend, the female plug 7 moves down until the female plug 7 and the male plug 6 are fully inserted, thus achieving electrical connection.

[0060] A pressure sensor 163 is provided in the limiting groove 136, and a microcontroller is provided on the charger body 2. The pressure sensor 163 is electrically connected to the cylinder 162 through the microcontroller.

[0061] When the limiting plate 134 engages with the limiting groove 136, the pressure sensor 163 receives the pressure from the limiting plate 134, converts the received signal into an electrical signal through the microcontroller and transmits it to the cylinder 162, triggering the cylinder 162 to extend, which in turn moves the female plug 7 downward to achieve connection.

[0062] A waterproof groove 171 is provided on the outer side of the charger body 2 located at the fixed base 5. The slot 1 is located in the upper part of the waterproof groove 171. A waterproof plate 172 is provided at the upper end of the waterproof groove 171 via a coil spring.

[0063] The waterproof groove 171 and waterproof plate 172 further prevent raindrops from entering the slot 1 during rainy weather.

[0064] Working principle: When assembling the plug 4 and slot 1, in the initial state, the connecting groove 9 of the sealing waterproof sleeve 8 is set downwards, that is, the end face of the arc-shaped rail 101 is connected to the first slide groove 102. Align the port of the first slide groove 102 with the slider 104 and push the plug 4 into the slot 1. During the pushing process, the slider 104 passes through the first slide groove 102 and enters the arc-shaped rail 101 from the port of the arc-shaped rail 101. During the movement, the slider 104 drives the sealing waterproof sleeve 8 to rotate 180 degrees. When the slider 104 passes the end of the sealing waterproof sleeve 8, the port of the sealing waterproof sleeve 8 is just connected to the second slide groove 103. Continue to push inwards, and the slider 104 enters the second slide groove 103 until the end face of the plug 4 is engaged with the innermost end of the slot 1. At this time, the sealing... The waterproof sleeve 8 and the male plug 6 are completely inside the slot 1, which can effectively prevent external rainwater from seeping into the connection between the male plug 6 and the female plug 7, ensuring the dryness of the connection and the safety of electrical connection. The connection slot 9, which was originally facing downward, is rotated to the top, and the male plug 6 is completely exposed and located directly below the female plug 7. When the locking block 131 engages with the locking slot 132, the pressure sensor 163 is triggered, which moves the female plug 7 downward until the female plug 7 and the male plug 6 are fully engaged. At this time, the female plug 7 and the male plug 6 are in an electrical connection state. When separating, the handle 153 is turned by finger, which pulls the internal steel wire rope 143 to move, thereby moving the limiting plate 134 closer to the locking block 131, so that it is disengaged from the limiting slot 136. At this time, the plug 4 can be easily pulled out of the slot 1.

[0065] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
