Description

Technical Field

[0001] The present invention relates to the field of in-vehicle ETC devices, and particularly to an in-vehicle ETC device that is convenient for installation. Background Art

[0002] In order to significantly improve the traffic efficiency of highway toll stations and driving convenience, modern vehicles are generally equipped with dedicated in-vehicle ETC terminal devices. The core value of this system lies in building an efficient and intelligent contactless interaction channel between vehicles and toll station infrastructure. When a driver enters the clearly marked ETC dedicated lane of a toll station, the highly sensitive induction terminal installed above or on the side of the toll station can automatically and accurately capture and read the unique identification signal containing vehicle identity information continuously emitted by the in-vehicle ETC device the moment the vehicle enters its working area. Through this non-contact wireless communication, the system can instantly complete the verification of vehicle identity and the calculation and processing of tolls, and finally achieve the goal of the vehicle passing through the toll gate without stopping for payment and passing smoothly. This process greatly optimizes the traffic experience and reduces the waiting time of traditional manual toll collection.

[0003] For the currently widely used in-vehicle ETC devices, the mainstream installation method is to directly fix its body on the inner side of the vehicle's front windshield using strong adhesives. Although this installation method is simple and effective, when the body of the ETC device is physically damaged due to accidental impact, aging or other reasons, or the built-in ETC card is accidentally demagnetized and fails due to long-term use or improper storage and needs to be repaired or replaced, the device disassembly process is inconvenient, and even if the device is finally removed, obvious and stubborn adhesive marks will almost inevitably remain in the originally pasted area. These residual glue stains are usually difficult to clean thoroughly. They not only adhere to the glass surface, affecting light transmittance and aesthetics, but also form a distinct mark on the glass compared with the surrounding clean area, damaging the original clean appearance of the windshield. Summary of the Invention

[0004] The purpose of the present invention is to provide an ETC vehicle-mounted ETC device that is easy to install, so as to solve the problem of using a strong adhesive to directly fix its body to the inside of the front windshield of the vehicle as proposed in the above background technology. Although this installation method is simple and effective, when the ETC device body is physically damaged due to accidental impact, aging or other reasons, or the built-in ETC card is accidentally demagnetized and invalid due to long-term use or improper storage, and needs to be repaired or replaced, the device disassembly process will be inconvenient, and even if the device is eventually removed, the area originally pasted will almost inevitably leave obvious and stubborn adhesive marks. These residual glue stains are usually difficult to clean thoroughly, and not only adhere to the glass surface, affecting the light transmittance and aesthetics, but also form a mark on the glass that is in sharp contrast to the surrounding clean area, destroying the original neat appearance of the windshield. In order to achieve the above purpose, the present invention provides the following technical solutions: an ETC vehicle-mounted ETC device that is easy to install, comprising a protective frame, a guide groove is provided on the top of the protective frame; It also includes a card block, which is slidably arranged inside the guide groove, and a mounting assembly for fixing the ETC card is slidably arranged inside the protection frame, and through grooves matching the mounting assembly are provided on both the front and rear sides of the inner wall of the protection frame; Rectangular grooves are provided on both the left and right sides of the bottom of the protection frame, and two slide grooves are provided on both the left and right sides of the top of the inner wall of the rectangular groove, and protective components are slidably arranged inside the slide grooves.

[0005] Preferably, the installation component includes a fixed frame, the fixed frame is slidably arranged inside the protective frame, the top of the fixed frame is fixedly matched with the card block, and the front and rear sides of the fixed frame are fixedly provided with a moving frame, and the side of the moving frame is slidably matched with the inside of the protective frame. This structural design realizes the overall sliding adjustment function of the installation component in the protective frame. The fixed frame serves as a core supporting frame, and its sliding setting allows the user to flexibly adjust the longitudinal position of the entire component in the protective frame according to installation requirements. The moving frame is fixed on both sides of the fixed frame and slidably matches with the inner wall of the protective frame, which significantly enhances the stability and guidance of the fixed frame during the sliding process, effectively prevents deflection or jamming, and ensures a smooth and accurate adjustment process; A clamping plate is slidably arranged inside the moving frame. The shapes of the clamping plate and the inside of the moving frame are both T-shaped. A first compression spring is fixedly arranged on the side surface of the vertical plate of the T-shaped clamping plate. One end of the first compression spring is fixedly matched with the inside of the moving frame. The side surface of the horizontal plate of the T-shaped clamping plate is slidably matched with the inside of the through groove. A long groove is formed at the bottom of the fixed frame. The matching design of the T-shaped clamping plate and the T-shaped groove inside the moving frame ensures that the clamping plate can only slide stably along a specific path. The first compression spring acts on the vertical plate of the clamping plate to provide a continuous elastic restoring force for it. The horizontal plate of the clamping plate is slidably matched with the through groove, so that its movement range is precisely controlled. Overall, this structure provides a reliable elastic sliding mechanism for the clamping plate, enabling it to displace under the action of an external force and automatically reset after the external force disappears, creating conditions for triggering or releasing the locked state.

[0006] Preferably, a connecting plate is fixedly arranged on the front side of the inner wall of the long groove. Rack bars are fixedly arranged on the left and right sides at the rear of the connecting plate. A threaded rod is rotatably arranged on the lower side of the inner wall of the protection frame. A driven gear is fixedly arranged at the top end of the threaded rod. The driven gear meshes with the rack bar. The connecting plate firmly connects the rack bar to the fixed frame and moves synchronously with it. The rack bar and the driven gear at the top end of the threaded rod form a meshing transmission relationship. When the threaded rod is rotated, the driven gear is driven to rotate, and then through the meshing of the gear and the rack bar, the rotational movement of the threaded rod is efficiently and precisely converted into the linear lifting movement of the rack bar and the fixed frame connected thereto.

[0007] Preferably, the bottom end of the threaded rod penetrates through the bottom of the protection frame and is fixedly provided with a suction cup. An arc-shaped groove matching the two suction cups is formed at the bottom of the protection frame. The bottom end of the threaded rod extends out of the protection frame and directly fixes the suction cup, so that the suction cup can rise and fall synchronously with the threaded rod. The arc-shaped groove at the bottom of the protection frame provides a storage space for the suction cup when it is not in use or during the rising process to protect the suction cup. When the threaded rod rotates downward, the suction cup extends out accordingly and can directly act on the automobile windshield, providing a firm adsorption and fixing force by using the negative pressure principle, greatly enhancing the anti-displacement and anti-tipping capabilities of the entire device on a smooth surface.

[0008] Preferably, the clamping block includes a rectangular frame which is slidably arranged inside the guiding groove. The middle part of the inner wall of the rectangular frame is movably inserted with an E-shaped block. The middle vertical block of the E-shaped block moves to the top of the rectangular frame. The length of the middle vertical block of the E-shaped block is twice the length of the left and right vertical blocks of the E-shaped block. A second compression spring is fixedly arranged at the bottom of the cross block of the E-shaped block. Slots which are matched with the left and right vertical blocks of the E-shaped block are formed at the bottom of the inner wall of the protection frame. The sliding of the rectangular frame in the guiding groove ensures the accuracy of the moving track of the clamping block. The E-shaped block is movably inserted into the rectangular frame through its middle long vertical block and has a tendency to move downward under the action of the second compression spring. The slots at the bottom of the protection frame are designed to accurately accommodate the left and right short vertical blocks of the E-shaped block. When the fixed frame slides to a specific position, under the elastic force of the second compression spring, the left and right short vertical blocks of the E-shaped block will quickly insert into the slots to form a mechanical lock, effectively preventing the fixed frame from sliding. The design of the middle long vertical block facilitates operation and provides sufficient stroke.

[0009] Preferably, four silica gel strips are fixedly arranged at the top of the rectangular frame. The tops of the four silica gel strips are on the same horizontal plane as the top of the protection frame. The silica gel strips arranged at the top of the rectangular frame have their tops flush with the top surface of the protection frame, forming a flat and continuous supporting contact surface. The silica gel material has excellent flexibility and a high friction coefficient. When in use and during operation, the silica gel strips can provide stable anti-slip support.

[0010] Preferably, the protection component includes four sliders which are respectively slidably arranged inside four chutes. The bottoms of two sliders in each group of the four sliders are fixedly provided with L-shaped plates. Protection plates are fixedly arranged on the opposite sides of the two L-shaped plates. The protection plates are slidably matched with the bottom of the protection frame. The side surface of the vertical plate of the L-shaped plate abuts against the side surface of the clamping plate. A baffle is fixedly arranged at the top of the vertical plate of the L-shaped plate. This protection component realizes the protection of the suction cup. The sliders slide in the chutes, driving the L-shaped plates and the protection plates to move. The two opposite protection plates can slide open and close at the bottom of the protection frame. When the clamping plate slides in the moving frame, it will push the vertical plate of the L-shaped plate, thereby driving the sliders, the L-shaped plates and the protection plates to move synchronously. The baffle is located at the top of the vertical plate of the L-shaped plate, increasing the structural strength and playing a role in limiting and guiding. The function of the protection plate is to close when the suction cup is retracted, covering and protecting the suction cup or other components below from dust pollution or external collision. When the suction cup needs to be extended, the protection plate automatically opens to make space.

[0011] Preferably, a groove is provided on the right side of the protective frame, and the upper side of the protective frame is rounded. The groove provided on the right side of the protective frame mainly provides a convenient force application point and operation space for the user to insert their finger to take the ETC card, improving the comfort and usability of the user's operation. The rounding process on the upper edge of the protective frame significantly improves the safety and aesthetics of the product. The rounded edge completely eliminates the risk of scratches that may be caused by sharp corners, making the product feel softer. At the same time, the smooth rounded corner line also gives the product a more modern and delicate visual appearance.

[0012] Compared with the prior art, the beneficial effects of the present invention are as follows: In the present invention, the fixed frame drives the two moving frames to move into the protective frame. At the same time, the fixed frame drives the connecting plate and the rack to move, and drives the driven gear, the threaded rod, and the suction cup to rotate and move downward. When the fixed frame moves in place, the T-shaped clamping plate moves outward through the first compression spring to limit and fix the driven gear, the threaded rod, and the suction cup. At the same time, the two L-shaped plates open to the front and rear sides at the same time to release the seal of the arc-shaped groove. At this time, the threaded rod drives the suction cup to move out of the arc-shaped groove, quickly fixing the ETC device on the windshield of the car, thereby preventing glue marks from appearing on the windshield of the car and ensuring the cleanliness and beauty of the windshield of the car.

[0013] In the present invention, by moving the E-shaped block downward, the fixation between the protective frame and the fixed frame is released. The silicone strip drives the rectangular frame and the fixed frame to move to the right, taking out the fixed block from the protective frame to release the fixation of the two L-shaped plates. At the same time, the two racks move forward, driving the two driven gears to rotate counterclockwise, causing the threaded rod and the suction cup to move upward, and the suction cup can be quickly received into the arc-shaped groove. At the same time, the two L-shaped plates are closed to the middle to protect the arc-shaped groove, and the suction cup can be quickly protected.

[0014] In the present invention, by moving the E-shaped block downward, the second compression spring is compressed, and the left and right vertical blocks of the E-shaped block move downward at the same time, moving out of the slot, releasing the fixation between the protective frame and the fixed frame. Thus, the fixed frame can drive the ETC card inside it to move out of the protective frame, and the ETC card can be quickly inspected and replaced, thereby increasing the speed of replacing and repairing the ETC card.

Detailed implementation manners

[0017] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0018] Please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Figure 9 , Figure 10 , Figure 11 , the present invention provides a technical solution: an ETC vehicle-mounted ETC device that is easy to install, including.

[0019] Example 1, please refer to Figure 2 ,Figure 3 , Figure 4 , Figure 5 , Figures 6 to 9 , this embodiment provides a technical solution: The installation component 4 includes a fixed frame 401, the fixed frame 401 is slidably arranged inside the protection frame 1, the top of the fixed frame 401 is fixedly matched with the clamping block 3, and moving frames 402 are fixedly arranged on both the front and rear sides of the fixed frame 401. The sides of the moving frames 402 are slidably matched with the inside of the protection frame 1; A clamping plate 403 is slidably arranged inside the moving frame 402. The shapes of the clamping plate 403 and the inside of the moving frame 402 are both T-shaped. A first compression spring 404 is fixedly arranged on the side of the vertical plate of the T-shaped clamping plate 403. One end of the first compression spring 404 is fixedly matched with the inside of the moving frame 402. The side of the horizontal plate of the T-shaped clamping plate 403 is slidably matched with the inside of the through groove 5. A long groove 405 is opened at the bottom of the fixed frame 401; A connecting plate 406 is fixedly arranged on the front side of the inner wall of the long groove 405. Rack bars 407 are fixedly arranged on both the left and right sides of the rear side of the connecting plate 406. A threaded rod 408 is rotatably arranged on the lower side of the inner wall of the protection frame 1. A driven gear 409 is fixedly arranged at the top of the threaded rod 408. The driven gear 409 is meshed with the rack bars 407; In this embodiment, when the fixed frame 401 moves into the protection frame 1, the displacement of the fixed frame 401 not only directly drives the connecting plate 406 fixedly connected thereto to move forward synchronously. More importantly, through the meshing of the rack 407 provided on the rear side of the connecting plate 406 with the driven gear 409 installed on the lower side of the inner wall of the protection frame 1, the linear motion is converted into rotational motion. The rotation of the driven gear 409 then drives the threaded rod 408 coaxially fixed thereto to start rotating. Due to the transmission characteristics of the thread pair, the rotation of the threaded rod 408 is precisely converted into its own downward movement along the axis. At the same time, the movement of the fixed frame 401 also pushes the two moving frames 402 on both sides to slide backward synchronously along the inner wall of the protection frame 1 through the moving frames 402 fixedly arranged on both sides thereof. When the fixed frame 401 completely moves to the preset locking position, the elastic potential energy stored in the first compression spring 404 inside the moving frame 402, which was compressed due to the movement of the fixed frame 401 and the moving frame 402, is released. Under the action of the elastic restoring force of the first compression spring 404, the T-shaped clamping plate 403 instantly obtains power and pops out along the T-shaped track inside the moving frame 402. At this time, the horizontal plate part of the clamping plate 403 is embedded into the preset through groove 5, and its side is in close fit with the inner wall of the through groove 5, forming a rigid mechanical interference. This action of the clamping plate 403 being embedded into the through groove 5 constitutes the most direct mechanical locking point, which complements the adsorption locking force generated by the downward movement of the threaded rod 408, jointly ensuring a tight and non-shaking fitting state between the fixed frame 401 and the main structure of the protection frame 1. When the device is in a non-use state, it protects the suction cup 4010, and when the device needs to be enabled, the user can conveniently and quickly release the lock of the clamping plate 403 and the pressure of the threaded rod 408 to achieve rapid release, which not only improves the durability of the device but also takes into account the convenience of user operation; Example 2, please refer to Figure 1 , Figure 2 , Figure 4 , Figure 7 , Figure 7 , Figure 10 , this embodiment provides a technical solution: The bottom end of the threaded rod 408 penetrates through the bottom of the protection frame 1 and is fixedly provided with a suction cup 4010. An arc-shaped groove 101 matching the two suction cups 4010 is opened at the bottom of the protection frame 1; The clamping block 3 includes a rectangular frame 301. The rectangular frame 301 is slidably arranged inside the guiding groove 2. The middle vertical block of the E-shaped block 302 is movably inserted into the middle of the inner wall of the rectangular frame 301. The middle vertical block of the E-shaped block 302 moves to the top of the rectangular frame 301. The length of the middle vertical block of the E-shaped block 302 is twice the length of the left and right vertical blocks of the E-shaped block 302. A second compression spring 303 is fixedly arranged at the bottom of the horizontal block of the E-shaped block 302. Slots 305 matching the left and right vertical blocks of the E-shaped block 302 are opened at the bottom of the inner wall of the protection frame 1; Four silicone strips 304 are fixedly arranged on the top of the rectangular frame 301, and the tops of the four silicone strips 304 are on the same horizontal plane as the top of the protection frame 1; In this embodiment, when the user needs to release the protection state to disassemble the device, a downward pressure is applied to the E-shaped block 302. This downward pressure directly acts on the protruding middle long vertical block of the E-shaped block 302 and is transmitted to its horizontal block part. The second compression spring 303 at the bottom of the horizontal block is stably compressed in this process, and elastic potential energy is stored inside. As the E-shaped block 302 moves downward as a whole, its shorter vertical blocks located on the front and rear sides move downward synchronously and slip out of the preset slots 305 at the bottom of the inner wall of the protection frame 1. This key action instantly releases the mechanical locking constraint of the E-shaped block 302 on the protection frame 1 and the fixed frame 401. After the lock is released, the connection relationship between the protection frame 1 and the fixed frame 401 is immediately separated, and the user can easily remove the main body of the device from the fixed frame 401 for necessary maintenance, replacement or adjustment. The operation process is intuitive and convenient. In view of the protection needs when the device is in an idle state, a special storage mechanism is designed. At this time, an adsorption fixation is provided. The functional suction cup 4010 will be completely retracted upward and stored in the arc groove 101 of the protection frame 1. After 4010 is completely embedded in the arc groove 101, its edge is in close contact with the groove wall, forming an effective sealed protection environment, thereby significantly isolating dust, moisture, ultraviolet rays and possible chemical pollutants in the outside air, effectively avoiding the rubber material of the suction cup 4010 from being continuously exposed to the air environment. Problems such as cracking, hardening, brittleness and even aging and deterioration are effectively avoided. By storing the suction cup 4010 in the sealed arc groove 101, the decay rate of its material properties is greatly slowed down, and the actual service life of the suction cup 4010, a key vulnerable component, is significantly extended. Finally, this thoughtful protective design ensures that the ETC device can maintain a good physical state and working performance whether it provides a stable adsorption force in daily use or is used again after long-term storage, providing a strong guarantee for the reliability and durability of the equipment; Example 3, please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 9 , Figure 10 , Figure 11 , this embodiment provides a technical solution: The protection component 8 includes four sliders 801 which are respectively and slidably arranged inside four chutes 7. The bottoms of the four sliders 801, with two as a group, are fixedly provided with L-shaped plates 802. On the opposite sides of the two L-shaped plates 802, protection plates 803 are fixedly provided. The protection plates 803 are in sliding fit with the bottom of the protection frame 1. The side surface of the vertical plate of the L-shaped plate 802 abuts against the side surface of the clamping plate 403. The top of the vertical plate of the L-shaped plate 802 is fixedly provided with a baffle 804; A groove 102 is formed on the right side of the protection frame 1, and the upper side of the protection frame 1 is all rounded; In this embodiment, the protection mechanism design of the ETC device fully considers the different requirements in the daily use and idle state. When the device is idle, the two symmetrically distributed L-shaped plates 802 will be accurately closed, and their horizontal parts perfectly fit with the bottom of the protection frame 1, thereby effectively protecting the bottom of the suction cup 4010 from dust pollution and physical damage, and also preventing accidental scratches that may occur during transportation or storage. When the user needs to use the ETC device, the two L-shaped plates 802 are smoothly unfolded. At this time, the suction cup 4010 is completely exposed and can firmly adsorb at the designated position on the car windshield, ensuring the stability of the device during driving and the reliability of signal transmission. The whole opening and closing process adopts a user-friendly design, which not only ensures the protection effect but also takes into account the convenience of use; The usage method and advantages of the present invention: The usage method of the ETC vehicle-mounted ETC device that is easy to install is as follows: Such as Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 、 Figure 6 、 Figure 7 、 Figure 8 、 Figure 9 、 Figure 10 、 Figure 11As shown in the figure: The fixed frame 401 drives the two moving frames 402 to move into the interior of the protection frame 1. At the same time, when the fixed frame 401 moves, it drives the connecting plate 406 and the rack 407 at its bottom to move, and through the rack 407, it causes the two driven gears 409 to rotate, thereby driving the threaded rod 408 and the suction cup 4010 to rotate and move downward. When the fixed frame 401 drives the ETC card inside it to move into place, the T-shaped clamping plate 403 on the inner wall of the moving frame 402 moves outward by the resilience of the first compression spring 404, so that the horizontal plate of the T-shaped clamping plate 403 abuts against the vertical plates of the two L-shaped plates 802, and the fixed rack 407 positions and fixes the driven gear 409, the threaded rod 408, and the suction cup 4010. At the same time, the two L-shaped plates 802 expand toward the front and rear sides simultaneously inside the two rectangular slots 6, releasing the sealed state of the arc-shaped slot 101. At this time, the threaded rod 408 drives the suction cup 4010 to move out from the inside of the arc-shaped slot 101, and the ETC device can be quickly fixed on the windshield of the car, thereby preventing glue marks from appearing on the windshield of the car and ensuring the cleanliness and beauty of the windshield of the car; By moving the E-shaped block 302 downward, the fixation between the protection frame 1 and the fixed frame 401 is released. Then, the rectangular frame 301 and the fixed frame 401 are driven to move to the right by the silicone strip 304, and the fixed block 401 is taken out from the inside of the protection frame 1, releasing the fixed state of the two L-shaped plates 802. At the same time, the two racks 407 at the bottom of the fixed frame 401 move forward, driving the two driven gears 409 to rotate counterclockwise, thereby driving the threaded rod 408 and the suction cup 4010 to move upward. The suction cup 4010 can be quickly received into the interior of the arc-shaped slot 101, and at the same time, the two L-shaped plates 802 are closed toward the middle through the two rectangular slots 6 to protect the arc-shaped slot 101, and the suction cup 4010 can be quickly protected; By moving the E-shaped block 302 downward, the second compression spring 303 is compressed, and the left and right vertical blocks of the E-shaped block 302 move downward simultaneously and move out from the inside of the slot 305, releasing the fixation between the protection frame 1 and the fixed frame 401. Thus, the ETC card inside the fixed frame 401 can be driven to move out from the inside of the protection frame 1, and the ETC card can be quickly inspected and replaced, thereby increasing the speed of replacing and repairing the ETC card.
