Description
Technical Field
[0001] The present invention relates to a vehicle-mounted cigarette lighter and a vehicle, and belongs to the technical field of vehicle accessories and vehicles. Background Art
[0002] As a device that provides power to the car, the car cigarette lighter is usually installed in the car. The car cigarette lighter usually has a standard 12V DC power socket, which is used to accept power-taking devices such as power plugs that are compatible with the cigarette lighter, thereby allowing various external devices, such as mobile phone chargers, air purifiers, driving recorders, etc., to access and use the car's power, making the car cigarette lighter a convenient in-car power interface.
[0003] However, during vehicle driving, especially on rough roads, the continuous vibration and shaking of the vehicle pose a severe challenge to the vehicle cigarette lighter and the power supply device connected to it. These vibrations may cause the physical connection between the power supply device and the vehicle cigarette lighter to become unstable, with slight looseness or intermittent separation between the contacts. This instability will not only lead to interruptions in power transmission, affecting the normal charging or operation of the power supply device, but may also cause damage to the power supply device due to sudden power outages. In addition, vibrations may also cause fluctuations in the contact resistance between the contacts, affecting the stable supply of current, which in turn has a negative impact on the performance of the power supply device, and further aggravates the wear and aging of the contacts, thereby shortening the service life of the vehicle cigarette lighter and the power supply device.
[0004] In view of the above, how to provide a vehicle-mounted cigarette lighter that can ensure the stability and reliability of the contact points even when used in an environment where the vehicle is vibrating and shaking, and ensure the stable operation of the vehicle-mounted cigarette lighter, is an issue that needs to be solved urgently. Summary of the invention
[0005] In order to solve the above technical problems of traditional vehicle cigarette lighters, the present invention provides a vehicle cigarette lighter and a vehicle. By using the vehicle cigarette lighter, a reliable connection between the contacts of the vehicle cigarette lighter and the power supply device can be ensured, ensuring that the vehicle cigarette lighter can operate stably to provide power to the power supply device.
[0006] Specifically, the first aspect of the present disclosure provides a vehicle-mounted cigarette lighter, comprising: a cigarette lighter body, which is embedded in the vehicle interior and has an upper end opening; a cover, which is arranged at the upper end of the cigarette lighter body and can be switched between an open state in which the opening is opened and a closed state in which the opening is closed; and a biasing portion, which is arranged at the cover or between the cigarette lighter body and the cover, and when the cover is in the open state, applies a biasing force to the cover so that the cover tends to switch to the closed state.
[0007] According to the vehicle-mounted cigarette lighter with the above-mentioned structure, it is provided with a closable cover. When using the cigarette lighter, the user can easily open the cover to light a cigarette or draw electricity, and can close the cover when not in use. This not only keeps the interior of the vehicle tidy, but also effectively prevents dust and debris from entering the cigarette lighter, reducing the risk of circuit short circuit or damage due to foreign matter, thereby improving the safety and convenience of use.
[0008] In addition, according to the vehicle-mounted cigarette lighter having the above structure, a biasing part is also provided. When the cigarette lighter is not in use, the cover can be kept in a closed state by the biasing force of the biasing part, and is not easy to be accidentally opened, which reduces the potential danger caused by children or pets accidentally touching the cigarette lighter due to curiosity to a certain extent, and provides additional safety protection for family members. When an external power-drawing device is inserted into the cigarette lighter to draw power using the cigarette lighter, the biasing part applies a biasing force to the cover so that the cover is pressed against the external power-drawing device. This pressing action ensures a good physical and electrical connection between the power-drawing device and the power contacts inside the cigarette lighter, reduces the problem of unstable power supply or connection failure caused by poor contact, thereby improving the reliability and efficiency of power drawing. Even if the vehicle vibrates due to uneven roads or driving operations during driving, the biasing part applies additional pressing force to the power-drawing device through the cover, so that a stable connection state can be maintained. In addition, due to the adjustable pressure provided by the biasing part, the cover can be appropriately compressed and adapted according to external power-drawing devices of different sizes, so that whether it is a thinner or thicker power-drawing plug, it can be firmly clamped in the cigarette lighter under the action of the biasing part, ensuring wide compatibility and flexibility of use. Furthermore, the automatic pressing function of the biasing part simplifies the installation process of the power-drawing device and provides a continuous and reliable power supply, allowing users to focus on driving tasks during driving and enjoy a more convenient and worry-free charging experience.
[0009] Preferably, in the vehicle-mounted cigarette lighter of the first aspect, the cover includes more than two sub-cover parts, and in the closed state of the cover, each of the sub-cover parts is located radially inward relative to the cigarette lighter body and abuts against each other, thereby closing the opening of the cigarette lighter body; each of the sub-cover parts is constructed to be able to rotate radially outward or radially inward relative to the cigarette lighter body, so that in the closed state of the cover, the cover is switched to the open state by rotating each of the sub-cover parts radially outward relative to the cigarette lighter body, and in the open state of the cover, the cover is switched to the closed state by rotating each of the sub-cover parts radially inward relative to the cigarette lighter body.
[0010] According to the vehicle-mounted cigarette lighter with the above-mentioned structure, since the sub-cover portion can be rotated in the radial direction relative to the cigarette lighter body, the cigarette lighter can easily adapt to external power-taking devices of different sizes and shapes. No matter whether it is a small or large power-taking device, it can find a suitable position and be firmly connected through an appropriate rotation angle. This wide compatibility ensures that users can get a reliable power-taking experience when using different devices, without having to worry about power supply problems caused by device incompatibility.
[0011] In addition, according to the vehicle-mounted cigarette lighter with the above structure, since it is equipped with more than two sub-cover parts, these sub-cover parts can work together under the action of the biasing part to uniformly press the inserted power-taking device from the radial outside to the radial inside, and ensure the all-round, balanced and reliable clamping of the power-taking device with more than two pressing points. When the external power-taking device is inserted into the cigarette lighter, the biasing part will drive each sub-cover part to fit tightly inward around the power-taking device, and the power-taking device is firmly clamped inside the cigarette lighter by using multiple pressing points, forming a stable and reliable electrical connection.
[0012] Preferably, in the vehicle cigarette lighter of the first aspect, the cover also includes an annular operating portion, which is arranged on the upper side relative to the sub-cover portion, and the operating portion is arranged in a manner linked to the sub-cover portion, so that when the operating portion is pressed, pulled or rotated, the sub-cover portion rotates radially outward or radially inward along with the pressing, pulling or rotation.
[0013] According to the vehicle-mounted cigarette lighter with the above-mentioned structure, the design of the annular operating part allows the user to easily operate the cigarette lighter cover without complicated movements or finding a specific operating point. Whether it is a pressing, pulling or rotating operation, it can be done intuitively and accurately through the operating part. The linkage mechanism between the operating part and the sub-cover part ensures the synchronization and consistency of the operation. The user only needs to apply force or rotate the operating part to trigger the corresponding action of the sub-cover part, without directly operating the sub-cover part, which greatly simplifies the operation process. In addition, the existence of the operating part also provides an extra layer of protection for the cigarette lighter, forming a circle of barriers on the top of the sub-cover part to avoid accidentally touching the sub-cover part.
[0014] Preferably, in the vehicle-mounted cigarette lighter of the first aspect, each of the sub-cover portions is provided with the biasing portion.
[0015] According to the vehicle-mounted cigarette lighter having the above-mentioned structure, the biasing part equipped on each sub-cover portion ensures that the power-taking device can be clamped evenly and firmly when inserted into the cigarette lighter. The biasing force provided by the biasing part enables the sub-cover portion to fit tightly around the power-taking device, reducing unstable power supply caused by poor contact or looseness.
[0016] Preferably, in the vehicle-mounted cigarette lighter of the first aspect, the cover is constructed as an upper flip cover connected to the cigarette lighter body by a hinge, which can be flipped up and down relative to the cigarette lighter body to open and close the opening, and the biasing portion is arranged on the hinge between the upper flip cover and the cigarette lighter body.
[0017] According to the vehicle-mounted cigarette lighter with the above structure, the design of the upper flip cover allows the user to open and close the opening of the cigarette lighter by simply flipping up and down, which is more intuitive and easy to operate. The biasing part is set at the hinge. When the cigarette lighter is not in use, the upper flip cover is in a closed state and can fit tightly to the cigarette lighter body to form an effective sealing barrier to prevent external pollutants such as dust and water vapor from entering the interior of the cigarette lighter, thereby protecting the electrical components and the power-taking device; when the cigarette lighter is in use, the opened upper flip cover can abut against the power-taking device under the action of the biasing part and press the power-taking device downward, thereby ensuring that the power-taking device can be stably inserted into the cigarette lighter body and reliably take electricity.
[0018] Preferably, in the vehicle-mounted cigarette lighter of the first aspect, the inner surface of the upper flip cover facing the cigarette lighter body is provided with one or more protrusions, wherein the plurality of protrusions are arranged in a zigzag shape along the flipping direction of the upper flip cover.
[0019] According to the vehicle-mounted cigarette lighter with the above-mentioned structure, the inner surface of the upper flip cover is provided with a protrusion, which can be used to more closely fit the power-taking device so as to engage and press the power-taking device downward, ensuring that the power-taking device is in close contact with the electrical contacts of the cigarette lighter body, thereby effectively preventing the power-taking device from slipping or loosening during the driving of the vehicle, and achieving a stable power-taking process. Secondly, the multiple protrusions arranged in a serrated shape can adapt to a variety of power-taking devices with different exposure heights, greatly improving the versatility and compatibility of the vehicle-mounted cigarette lighter. Whether it is a traditional cigarette lighter plug or a modern power-taking device such as a charging cable and an adapter of various sizes and shapes, it can be matched with a corresponding protrusion and firmly fixed by the serrated protrusion in the upper flip cover, which not only improves the convenience of the user, but also ensures that a reliable power-taking process can be achieved regardless of the type or size of the power-taking device.
[0020] Preferably, in the vehicle cigarette lighter of the first aspect, at least a surface of each protrusion on the hinge side is an inclined surface, and the inclined surface extends in a direction away from the hinge as it moves away from the inner surface of the upper flip cover.
[0021] According to the vehicle-mounted cigarette lighter with the above-mentioned structure, when the upper flip cover of the vehicle-mounted cigarette lighter rotates toward the closed position driven by the biasing part, the surface of each protrusion located on the hinge side, i.e. the inclined surface, gradually approaches and finally abuts against the power collection device as the upper flip cover rotates, and its angle gradually tends to be horizontal, ensuring that the protrusion can more firmly wrap around and press the power collection device from above, significantly enhancing the stability and reliability during the power collection process, making the contact between the cigarette lighter and the power collection device closer, and effectively reducing the problem of unstable power transmission caused by looseness or misalignment, thereby providing users with a safer and smoother use experience.
[0022] Preferably, in the vehicle-mounted cigarette lighter of the first aspect, the protruding heights of the plurality of protrusions gradually increase in a direction away from the hinge.
[0023] According to the vehicle-mounted cigarette lighter with the above-mentioned structure, for a variety of power-taking devices with different exposed heights, the upper flip cover can be reliably used to press down the power-taking device, which greatly improves the versatility and compatibility of the vehicle-mounted cigarette lighter. For example, if the height of the power-taking device exposed upward when inserted into the cigarette lighter body is higher, then the upper flip cover is pressed against the power-taking device in a state closer to being upright. However, since the protruding height of the protrusion gradually increases in the direction away from the hinge, even for a power-taking device with a larger exposed height, a protrusion with a higher protruding height can be used to press it, thereby ensuring close contact between the cigarette lighter and the power-taking device, and ensuring a stable and reliable connection between the contact points of the cigarette lighter body and the power-taking device.
[0024] Preferably, in the vehicle cigarette lighter of the first aspect, the upper flip cover further comprises: a magnet which is embedded in the upper flip cover body, so that when the upper flip cover is in a fully opened position, the magnet in the upper flip cover body is attracted to a matching magnet arranged on the vehicle, thereby maintaining the upper flip cover in a fully opened state.
[0025] According to the vehicle cigarette lighter having the above structure, when the upper flip cover needs to be kept in an open state, the upper flip cover is placed in a fully open position. In this position, the adsorption force between the magnets is greater than the biasing force of the biasing part, so that the upper flip cover can stay stably in a predetermined position after opening, making it convenient for users to access or replace the power supply device at any time, thereby improving the convenience of operation.
[0026] The vehicle-mounted cigarette lighter according to the first aspect of the present disclosure has been described above. In addition, the second aspect of the present disclosure further provides a vehicle, the vehicle comprising the vehicle-mounted cigarette lighter according to the first aspect.
[0027] The vehicle of the second aspect can also achieve the same technical effect because it adopts the vehicle-mounted cigarette lighter of the first aspect.
[0028] The basic structure and technical effects of the vehicle-mounted cigarette lighter of the first aspect and the vehicle of the second aspect of the present disclosure have been described above. The technical solution of the present disclosure will be more easily understood by describing the details with reference to the accompanying drawings. BRIEF DESCRIPTION OF THE DRAWINGS

[0060] The vehicle is equipped with a vehicle cigarette lighter 100, which is usually located below the center console or near the armrest box, so that the driver can reach it easily. Figure 4 As shown in or 5: it includes a cigarette lighter body 10 hidden in the vehicle interior 200. The shape of the cigarette lighter body 10 is mostly a bottomed cylinder with an open top. The inner wall of the cylinder is provided with a raised metal point as a contact 11, which is similar to a small power interface as a whole. In addition to the traditional cigarette-lighting function, the vehicle-mounted cigarette lighter 100 can also be used as a power interface. When an adapted power-taking device is inserted, it can charge various electronic devices such as mobile phones, vehicle-mounted vacuum cleaners, and driving recorders. It greatly expands the convenience of using electricity in the car. It is one of the indispensable convenience facilities in modern cars. It not only meets the driver's smoking needs, but also expands the scope of use of the vehicle's power supply, and improves the comfort and convenience during driving. The contact 11 in the figure is drawn only for the convenience of explanation and is not the actual shape and position.
[0061] The vehicle-mounted cigarette lighter 100 of the present disclosure is provided with a cover 20 located at the upper end of the cigarette lighter body 10 and capable of switching between an open state of opening the opening of the cigarette lighter body and a closed state of closing the opening. By using the vehicle-mounted cigarette lighter 100 of the present disclosure, a reliable connection between the contact points of the power-collecting device 300 can be ensured, ensuring that the vehicle-mounted cigarette lighter 100 can operate stably to provide power to the power-collecting device 300.
[0062] <First Embodiment>
[0063] Figure 1 to Figure 3 The first embodiment of the present disclosure is described, and the plan schematic diagrams are shown from a top-down perspective, and only the main components are depicted, and other unnecessary components are omitted.
[0064] In the vehicle-mounted cigarette lighter 100 of the first embodiment, the cover 20 disposed on the upper end of the cigarette lighter body 10 is, for example, Figure 1 and Figure 3 The cover 20 is composed of three sub-cover portions 21, and a biasing portion 30 such as a coil spring is provided on each sub-cover portion 21, so that when the cover 20 is in Figure 3In the open state shown, the biasing portion 30 can apply a biasing force to the cover 20 that tends to switch the cover 20 to the closed state.
[0065] like Figure 1 As shown, when the cover 20 is closed, each sub-cover plate portion 21 is located radially inward relative to the cigarette lighter body 10 and butted against each other, thereby closing the opening of the cigarette lighter body 10. Each sub-cover plate portion 21 is configured to be able to rotate radially outward (opening direction) or radially inward (closing direction) relative to the cigarette lighter body 10. Figure 1 In the closed state of the cover 20 shown in FIG. 1 , each sub-cover plate portion 21 is rotated radially outward relative to the cigarette lighter body 10 as shown by the arrow, so that the cover 20 is Figure 3 On the other hand, in Figure 3 In the open state of the cover 20 shown in the figure, by rotating each sub-cover plate portion 21 inwardly in the radial direction relative to the cigarette lighter body 10, that is, in the closing direction, the cover will return to the Figure 1 Shown in closed state.
[0066] In the vehicle cigarette lighter 100 of the first embodiment, the above-mentioned opening or closing operation of each sub-cover portion 21 can be performed by the annular operating portion 23. The operating portion 23 is arranged on the upper side relative to the sub-cover portion 21, and the operating portion 23 is arranged in a manner of interlocking with the sub-cover portion 21, so that when the operating portion 23 is pressed, pulled or rotated, the sub-cover portion 21 rotates radially outward or radially inward along with the pressing, pulling or rotating, thereby realizing the opening or closing of the cover 20.
[0067] like Figure 2 As shown, each sub-cover portion 21 has a rotating shaft 22 extending up and down, and the rotating shaft 22 can be set at a corner of the radial outer side of each sub-cover portion 21, and each sub-cover portion 21 can rotate around its own rotating shaft 22. A transmission mechanism such as a connecting rod, a cam, a gear rack, etc. can be set between the operating portion 23 and the sub-cover portion 21, and the operation of the operating portion 23 is converted into a rotation operation of the sub-cover portion 23 around the rotating shaft 22 through the transmission mechanism. For example, when the operating portion 23 is pressed down or pulled up, the operating portion 23 presses down or pulls up the rotating shaft 22, and the transmission mechanism is activated after the rotating shaft 22 is pressed down or pulled up, so that the sub-cover portion 21 rotates, and when the operating portion 23 is released, the opposite action is performed; or when the operating portion 23 is rotated, the transmission mechanism is activated, so that the sub-cover portion 21 rotates, and when the operating portion 23 is released, the opposite action is performed; or when the operating portion 23 is rotated, the transmission mechanism is activated, so that the sub-cover portion 21 rotates, and when the operating portion 23 is released, the opposite action is performed.
[0068] like Figures 1 to 3 As shown, the biasing portion 30 provided on each sub-cover portion 21 may be a coil spring, one end of which is connected to the sub-cover portion 21 and the other end of which is connected to the vehicle. Figure 1When the cover 20 is closed, the biasing portion 30 is in a free state, more preferably in a slightly compressed state, so that a reaction force can be applied to each sub-cover portion 20, so that each sub-cover portion 21 is tightly docked together and maintained in a closed state. Figure 2 or Figure 3 When the sub-cover portions 21 of the cover 20 shown are in the opened state, the biasing portion 30 is greatly compressed and the elastic force is accumulated. Therefore, when the operation of the operating portion 23 is released, for example, when the user's hand is released from the operating portion 23, each sub-cover portion 21 is pushed by the elastic restoring force of the biasing portion 30 and rotates toward the closing direction.
[0069] Figures 1 to 3 The sub-cover plate parts 21 and the biasing part 30 shown are arranged on the lower side of the panel of the vehicle interior, and a space for accommodating each sub-cover plate part 21 is reserved on the lower side of the lower surface of the panel, so that each sub-cover plate part 21 enters and moves out of the space with the opening and closing of the cover 20. In addition, a track part can also be arranged in the space to guide the rotation of the corresponding sub-cover plate part 21.
[0070] The basic structure of the vehicle-mounted cigarette lighter 100 according to the first embodiment has been described above. Next, the operation of charging using the vehicle-mounted cigarette lighter 100 will be described.
[0071] First, the operator operates the operation portion 23 to rotate each sub-cover portion 21 radially outward, that is, in the opening direction, to enter the open state. At this time, the biasing portion 30 is greatly compressed.
[0072] Then, the power taking device 300 is inserted into the cigarette lighter body 10, so that the power taking device 300 and the contact 11 of the cigarette lighter body 10 are connected to each other to realize power supply. Charging devices such as mobile phones can be continuously charged by connecting to the power taking device 300.
[0073] Next, the user releases the operating portion 23, and each sub-cover portion 23 rotates radially inward, that is, in the closing direction, under the force of the biasing portion 23 until it contacts the outer periphery of the power extraction device 300. Figure 3 At this time, each sub-cover portion 23 evenly applies clamping force to the power-drawing device 300 at three positions, and the power-drawing device 300 can be reliably held in the cigarette lighter body 10 without accidental displacement or loosening.
[0074] In addition, it should be noted that in the above description, the number of sub-cover portions 21 is described as 3, but this is not restrictive, and there is no limit to the number, as long as it is 2 or more. In addition, the shape of the sub-cover portion 21 is described as dividing a circle into 120° equal parts, but this is not restrictive and can be divided arbitrarily. In addition, the portion of each sub-cover portion 21 that docks with other sub-cover portions 21 can be provided with an elastic soft portion, so that each sub-cover portion 21 can fit more closely, and each sub-cover portion 21 can use the soft portion to clamp the power-collecting device 300, which is more closely attached and not easy to damage the power-collecting device 300.
[0075] According to the vehicle-mounted cigarette lighter 100 of the first embodiment with the above-mentioned structure, since the sub-cover portion 21 can rotate in the radial direction relative to the cigarette lighter body 10, the cigarette lighter 100 can easily adapt to external power-taking devices 300 of different sizes and shapes. No matter whether it is a small or large power-taking device 300, it can find a suitable position and be firmly connected through an appropriate rotation angle. This wide compatibility ensures that users can obtain a reliable power-taking experience when using different devices, without having to worry about power supply problems caused by device incompatibility.
[0076] In addition, according to the vehicle-mounted cigarette lighter 100 of the first embodiment having the above-mentioned structure, since it is equipped with more than two sub-cover portions 21, these sub-cover portions 21 can work together under the action of the biasing portion 30 to uniformly press the inserted power-taking device 300 from the radial outside to the radial inside, and ensure the all-round, balanced and reliable clamping of the power-taking device with more than two pressing points. When the power-taking device 300 is inserted into the cigarette lighter body 10, the biasing portion 30 will drive each sub-cover portion 21 to fit tightly inward around the power-taking device 300. Using multiple pressing points, the power-taking device 300 is firmly clamped inside the cigarette lighter, forming a stable and reliable electrical connection.
[0077] According to the vehicle-mounted cigarette lighter 100 of the first embodiment having the above-mentioned structure, the design of the annular operating part 23 allows the user to easily operate the cigarette lighter cover 20 without complicated movements or finding a specific operating point. Whether it is a pressing, pulling or rotating operation, it can be completed intuitively and accurately through the operating part. The linkage mechanism between the operating part 23 and the sub-cover part 21 ensures the synchronization and consistency of the operation. The user only needs to apply force or rotate the operating part to trigger the corresponding action of the sub-cover part, without directly operating the sub-cover part 21, which greatly simplifies the operation process. In addition, the existence of the operating part 23 also provides an extra layer of protection for the cigarette lighter, forming a circle of barriers for the sub-cover part on the top to avoid accidentally touching the sub-cover part 21.
[0078] <Second Embodiment>
[0079] Figure 4 and Figure 5 The second embodiment of the present disclosure is shown in FIG. The cigarette lighter body 10 of the vehicle cigarette lighter 100 of the second embodiment is the same as that of the first embodiment, and the difference lies in the cover 20 and the biasing portion 30 .
[0080] In the second embodiment, the cover 20 of the vehicle cigarette lighter 100 is as follows: Figure 4 and Figure 5 The upper flip cover 24 is connected to the cigarette lighter body 10 via a hinge 25 and can be flipped up and down relative to the cigarette lighter body 10 to open and close the opening at the upper end of the cigarette lighter body 10 , and the biasing portion 30 is disposed on the hinge 25 between the upper flip cover 24 and the cigarette lighter body 10 .
[0081] like Figure 4 and Figure 5 As shown, the inner surface of the upper flip cover 24 facing the cigarette lighter body 10 is provided with a plurality of protrusions 26, wherein the plurality of protrusions 26 are arranged in a sawtooth shape along the flipping direction of the upper flip cover. Each protrusion 26 has a first surface 27 on the hinge 25 side and a second surface 28 on the opposite side of the hinge 25. The first surface 27 can be set as an inclined surface, extending in a direction away from the hinge 25 as it moves away from the inner surface of the upper flip cover 24. As shown in the figure, the protrusion heights of the plurality of protrusions 26 can be gradually increased in the direction away from the hinge 25, but this is not restrictive, and the protrusion heights can also be the same.
[0082] It should be noted that the number of protrusions 26 is not limited to that shown in the figure, as long as there is more than one, or no protrusions are provided. The protrusions 26 are not limited to being sawtooth-shaped, and may also be long strips, truncated cones, frustums, etc. In addition, the second surface 28 may be an inclined surface or not.
[0083] like Figure 4 and Figure 5 As shown, the upper flip cover 24 of the vehicle cigarette lighter 100 further includes: a magnet 29 which is embedded in the upper flip cover body, so that when the upper flip cover 24 is in Figure 5 When the upper flip cover 24 is in the fully opened position shown in FIG. 1 , the magnet 29 in the upper flip cover body is attracted to the matching magnet 210 provided on the vehicle, thereby maintaining the fully opened state of the upper flip cover 24. Therefore, when the upper flip cover 24 needs to be kept in the open state, the upper flip cover 24 is in the fully opened state. Figure 5 The fully open position shown in the figure, in this position, the adsorption force between the magnets 29 and 210 is greater than the biasing force of the biasing part 30, so that the upper flip cover 24 can stay stably in the predetermined position after opening, which is convenient for the user to access or replace the power supply device 300 at any time, thereby improving the convenience of operation.
[0084] In the second embodiment, the upper flip cover 24 is connected to the cigarette lighter body 10 by a hinge 25, and the hinge 25 can be a hinge with an automatic closing function, that is, the hinge 25 can be provided with a biasing portion 30, so that when the upper flip cover 24 is opened, the biasing portion 30 at the hinge 25 can apply a force to the upper flip cover 24, so that the upper flip cover 24 tends to rotate in the closing direction under the force. The biasing portion 30 arranged at the hinge 25 can be a wound leaf spring, for example, one end of the leaf spring is pressed against the outer surface of the upper flip cover 20, so that when the upper flip cover 24 is opened, one end of the leaf spring is elastically deformed by force, and an elastic restoring force is generated on the upper flip cover 24 to rotate in the closing direction. Of course, the arrangement of the leaf spring is only an example of the biasing portion at the hinge 25, and any other form can be adopted as long as the force applied to the upper flip cover can be achieved.
[0085] The basic structure of the vehicle-mounted cigarette lighter 100 according to the second embodiment has been described above. Next, the operation of charging using the vehicle-mounted cigarette lighter 100 will be described.
[0086] First, the operator operates the upper flip cover 24, flips the upper flip cover 24 upward around the hinge 25 to be in an open state, and the magnet 29 of the upper flip cover 24 is adsorbed to the matching magnet 210 provided in the vehicle interior panel 200, and the upper flip cover 24 is kept in the open state by the adsorption force, as shown in FIG. Figure 4 At this time, the biasing portion 30 at the hinge 25 is in an elastically deformed state.
[0087] Then, the power taking device 300 is inserted into the cigarette lighter body 10, so that the power taking device 300 and the contact 11 of the cigarette lighter body 10 are connected to each other to realize power supply. Charging devices such as mobile phones can be continuously charged by connecting to the power taking device 300.
[0088] Next, the user lifts the upper flip cover 24, and the upper flip cover 24 flips toward the closing direction under the elastic restoring force of the biasing portion 30 until it abuts against the upper part of the power taking device 300. Figure 5 At this time, the first surface 27 of the protrusion 26 of the upper flip cover 24 contacts and is stuck to the upper part of the power-drawing device 300, and the elastic restoring force of the biasing part 300 continuously applies a squeezing force to the power-drawing device 300, so that the power-drawing device 300 is firmly held in the cigarette lighter body 10 without displacement or loosening.
[0089] According to the vehicle-mounted cigarette lighter 100 of the second embodiment having the above-mentioned structure, the design of the upper flip cover 34 allows the user to open and close the opening of the cigarette lighter by simply flipping up and down, which is more intuitive and easy to operate. The biasing part 30 is arranged at the hinge 25. When the cigarette lighter is not in use, the upper flip cover 34 is in a closed state and can fit tightly to the cigarette lighter body to form an effective sealing barrier to prevent external pollutants such as dust and water vapor from entering the interior of the cigarette lighter, thereby protecting the electrical components and the power-drawing device; when the cigarette lighter is in use, the opened upper flip cover 24 can abut against the power-drawing device 300 under the action of the biasing part 30 and press the power-drawing device 300 downward, thereby ensuring that the power-drawing device 300 can be stably inserted into the cigarette lighter body 10 and reliably draw electricity.
[0090] According to the vehicle-mounted cigarette lighter 100 of the second embodiment having the above-mentioned structure, the inner surface of the upper flip cover 24 is provided with a protrusion 26, which can be used to more closely fit the power-taking device 300 so as to engage and press the power-taking device 300 downward, ensuring that the power-taking device 300 is in close contact with the electrical contacts of the cigarette lighter body 10, thereby effectively preventing the power-taking device 300 from slipping or loosening during the driving of the vehicle, and achieving a stable power-taking process. Secondly, the multiple protrusions 300 arranged in a serrated pattern can adapt to a variety of power-taking devices with different exposure heights, greatly improving the versatility and compatibility of the vehicle-mounted cigarette lighter. Whether it is a traditional cigarette lighter plug or a modern charging plug, adapter or other power-taking device of various sizes and shapes, it can be matched with a corresponding protrusion 300 and firmly fixed by the serrated protrusion in the upper flip cover, which not only improves the convenience of the user, but also ensures that a reliable power-taking process can be achieved regardless of the type or size of the power-taking device.
[0091] According to the vehicle cigarette lighter 100 of the second embodiment with the above-mentioned structure, when the upper flip cover 24 of the vehicle cigarette lighter 100 rotates toward the closed position under the drive of the biasing part 300, the surface of each protrusion 26 located on the hinge side, that is, the first surface, is an inclined surface. As the upper flip cover 24 rotates gradually approaches and finally abuts against the power collection device 300, the angle of the inclined surface gradually tends to be horizontal, ensuring that the protrusion can more firmly wrap around and press the power collection device 300 from above, significantly enhancing the stability and reliability during the power collection process, making the contact between the cigarette lighter and the power collection device closer, and effectively reducing the problem of unstable power transmission caused by looseness or misalignment, thereby providing users with a safer and smoother use experience.
[0092] According to the vehicle-mounted cigarette lighter 100 of the second embodiment having the above-mentioned structure, the protrusion 26 has different protruding heights, so for a variety of power-taking devices with different exposed heights, the upper flip cover 24 can be reliably used to press down the power-taking device 300, which greatly improves the versatility and compatibility of the vehicle-mounted cigarette lighter. For example, if the power-taking device 300 is exposed higher when inserted into the cigarette lighter body, then the upper flip cover 24 is pressed against the power-taking device in a state closer to being upright. However, since the protruding height of the protrusion 26 gradually increases in the direction away from the hinge, even for a power-taking device with a larger exposed height, a protrusion 26 with a higher protruding height can be used to press it, thereby ensuring close contact between the cigarette lighter and the power-taking device, and ensuring a stable and reliable connection between the contact points of the cigarette lighter body 10 and the power-taking device 300.
[0093] <Third Embodiment>
[0094] A third embodiment of the present disclosure provides a vehicle, which is provided with the vehicle-mounted cigarette lighter 100 of the first embodiment or the second embodiment, and can also achieve the same technical effects as the first embodiment and the second embodiment.
[0095] It should be noted that in the above-mentioned embodiments, the biasing part is taken as an example of a spring, but this is not restrictive. For example, it can also be an elastomer, elastic material, etc. that can store energy.
[0096] To sum up, according to the vehicle-mounted cigarette lighter disclosed in the present invention, it is provided with a switchable cover. When using the cigarette lighter, the user can easily open the cover to light a cigarette or draw electricity, and can close the cover when not in use. This not only keeps the interior of the vehicle tidy, but also effectively prevents dust and debris from entering the cigarette lighter, reducing the risk of circuit short circuit or damage due to foreign objects, thereby improving the safety and convenience of use.
[0097] In addition, according to the vehicle-mounted cigarette lighter disclosed in the present invention, a biasing part is also provided. When the cigarette lighter is not in use, the cover can be kept in a closed state by the biasing force of the biasing part, and is not easy to be accidentally opened, which reduces the potential danger caused by children or pets accidentally touching the cigarette lighter out of curiosity to a certain extent, and provides additional safety protection for family members. When an external power-drawing device is inserted into the cigarette lighter to draw power using the cigarette lighter, the biasing part applies a biasing force to the cover so that the cover is pressed against the external power-drawing device. This pressing action ensures a good physical and electrical connection between the power-drawing device and the power contacts inside the cigarette lighter, reduces the problem of unstable power supply or connection failure caused by poor contact, thereby improving the reliability and efficiency of power drawing. Even if the vehicle vibrates due to uneven roads or driving operations during driving, the biasing part applies additional pressing force to the power-drawing device through the cover, so that a stable connection state can be maintained. In addition, due to the adjustable pressure provided by the biasing part, the cover can be appropriately compressed and adapted according to external power-drawing devices of different sizes, so that whether it is a thinner or thicker power-drawing plug, it can be firmly clamped in the cigarette lighter under the action of the biasing part, ensuring wide compatibility and flexibility of use. Furthermore, the automatic pressing function of the biasing part simplifies the installation process of the power-drawing device and provides a continuous and reliable power supply, allowing users to focus on driving tasks during driving and enjoy a more convenient and worry-free charging experience.
