Description

Technical Field

[0001] This invention belongs to the field of vehicle dashcam technology, and particularly relates to an integrated anti-poor contact assembly structure for vehicle dashcams. Background Technology

[0002] Most existing vehicle dashcams adopt a decentralized assembly design. Various functional components (such as touchpad, display screen, speaker, etc.) are electrically connected through multiple independent connecting wires. The motherboard is directly installed in the limited space inside the shell without a dedicated heat dissipation and electromagnetic shielding structure. The memory card slot, buttons, etc. adopt a traditional exposed or decentralized design. The button battery is fixedly connected to the motherboard and cannot be removed. The support structure is simple and only relies on the edge of the shell for installation.

[0003] The existing technology has the following problems:

[0004] The large number and messy layout of the connecting wires lead to a higher risk of poor contact between components, which can easily cause equipment to freeze, malfunction, and other faults, while also increasing the difficulty of troubleshooting.

[0005] The casing has limited space to accommodate the motherboard, and the motherboard lacks a dedicated heat dissipation structure, so heat cannot be dissipated in time. Long-term use can easily damage electronic components due to overheating and shorten the lifespan of the device.

[0006] The external wiring interface adopts a simple plug-in design without reinforcement structure, which is prone to loosening and falling off under the influence of vehicle vibration, further aggravating the problem of poor contact.

[0007] The memory card slot design is unreasonable, requiring tools to insert and remove it, making the operation cumbersome and inconvenient to use;

[0008] The button battery is fixedly connected to the motherboard and cannot be replaced separately. When the battery life expires, it will cause inaccurate time recording of the device, affecting the performance.

[0009] The buttons are installed in a distributed manner and need to be connected to the motherboard via a separate cable, which increases the number of wires and the probability of poor contact failure.

[0010] The motherboard lacks an electromagnetic shielding structure, making it susceptible to electromagnetic interference from both inside and outside the vehicle, resulting in unstable signal transmission and affecting image quality and functional response speed.

[0011] It is only equipped with small-capacity storage interfaces such as TF memory cards, and no large-capacity storage expansion interfaces are reserved, which cannot meet the user's needs for long-term, high-definition video storage.

[0012] The assembly of each component is complex, lacks a precise positioning structure, requires multiple adjustments to the alignment during the assembly process, resulting in low production and assembly efficiency and high labor costs.

[0013] Lacking a dedicated support and fixing structure, the shell relies solely on the edge of the outer shell to adhere to the mounting surface after installation. This makes it prone to displacement when the vehicle vibrates, leading to loose connections of internal components.

[0014] Therefore, an integrated anti-poor contact assembly structure for vehicle dashcams is needed to solve the above problems. Summary of the Invention

[0015] The purpose of this invention is to provide an integrated anti-poor contact assembly structure for vehicle recorders to solve the problems mentioned in the background art.

[0016] To achieve the above objectives, the present invention provides the following technical solution:

[0017] An integrated anti-poor contact assembly structure for a vehicle dashcam includes a touchpad, a mid-frame, a tail cover, a sliding slider, a display screen, a motherboard, and a support component.

[0018] The back of the touchpad is detachably snapped to the middle frame. The display screen is embedded in the touchpad. The tail cover is correspondingly snapped to the back of the middle frame. A sliding groove is provided on one side of the tail cover, and a speaker hole is provided on the back of the tail cover. The movable slider is slidably connected in the sliding groove. A speaker is fixedly installed inside the tail cover. The speaker is electrically connected to the speaker socket on the motherboard through a cable.

[0019] The touchpad is fixedly connected to one end of a flexible first ribbon cable and a second ribbon cable, respectively. The other ends of the first and second ribbon cables are fixedly connected to a plug-in structure. The plug-in structure is detachably plugged into the back of the motherboard and electrically connected to the ribbon cable interface of the motherboard. The motherboard is adapted to be installed in a placement slot provided on the inner side of the middle frame. The surface of the motherboard is electrically connected to a button battery structure, a TF memory card slot, a USB flash drive slot, and a reserved SATA interface. The surface of the motherboard is fixedly covered with a shielding cover. A heat sink is fixedly connected to the outer side of the shielding cover. The support is detachably fixedly connected to the middle area of ​​the back of the tail cover.

[0020] In a further technical solution, the support component includes an arc-shaped support plate and two sets of symmetrically arranged connecting seats. The connecting seats are detachably connected to the threaded holes pre-set on the back of the tail cover by bolts. The arc-shaped support plate and the connecting seats are integrally formed.

[0021] In a further technical solution, the first and second ribbon cables are FFC flexible ribbon cables, and the plug-in structure is provided with a limiting buckle, which is adapted to and engaged with a pre-set slot on the back of the motherboard.

[0022] In a further technical solution, a through groove is provided at the bottom of the placement slot of the middle frame.

[0023] In a further technical solution, the shielding cover is made of metal and is fixed to the surface of the motherboard by welding or bolts.

[0024] In a further technical solution, the heat sink is an aluminum heat sink with multiple heat dissipation fins on its surface, and is fixed to the shielding cover by thermally conductive silicone grease.

[0025] In a further technical solution, the TF memory card slot and the USB flash drive slot are hidden structures with their openings facing the slide groove. When the slider is moved to the closed position, the slots are completely covered.

[0026] In a further technical solution, the button battery structure includes a battery holder and a removable button battery, with the battery holder fixed to the motherboard surface by welding.

[0027] In a further technical solution, the horn is fixed in a pre-set mounting groove inside the tail cover by a buckle or bolt, and the sound-producing surface of the horn is set to correspond to the sound-emitting hole.

[0028] In a further technical solution, the inner side of the movable slider is provided with a guide strip, the inner wall of the slide groove is provided with a guide groove adapted to the guide strip, and the outer side of the movable slider is provided with anti-slip texture.

[0029] Compared with the prior art, the beneficial effects of the present invention are:

[0030] This invention reduces the risk of poor contact: by integrating the touchpad with the middle frame and tail cover through a snap-fit / fastening method, and coordinating the centralized connection of the first and second ribbon cables with the plug-in structure, it replaces the traditional distributed multi-connection cable design, reducing wiring nodes and clutter; the plug-in structure precisely plugs into the back of the motherboard, and the limiting buckle provides secondary fixation, effectively reducing the risk of poor contact and solving the problem of failure caused by multiple connection cables;

[0031] This invention improves heat dissipation performance: the motherboard is fitted and installed in the placement slot of the middle frame to obtain reasonable heat dissipation space; a metal shield is fixed on the surface of the motherboard, and an aluminum heat sink is connected to its outer side. The heat sink increases the heat dissipation area through heat dissipation fins, which quickly conducts heat, solves the problem of insufficient heat dissipation of the motherboard, and extends the service life of electronic components.

[0032] This invention enhances the reliability of interface connections: the speaker is directly connected to the motherboard's speaker port via a short-distance cable, replacing traditional long-distance external wiring; all interfaces are integrated on the motherboard surface, reducing the use of external wiring, avoiding interface loosening caused by vibration, and solving the problem of unreliable external wiring interfaces;

[0033] This invention improves the ease of inserting and removing memory cards: the TF memory card slot and USB flash drive slot adopt a hidden design, combined with the sliding protection of the sliding slider, so that users can insert and remove storage devices by hand without tools, which is convenient and solves the problem of needing tools to insert and remove memory cards;

[0034] This invention enables the replacement of button batteries: the button battery structure is designed to be detachable, and the user can directly push the sliding block to push it out of the slide groove. At this time, the button battery structure is exposed, and the battery can be replaced directly without disassembling the entire device, ensuring the accuracy of the device's time recording and solving the problem of non-replaceable button batteries.

[0035] This invention reduces the probability of button failure: the buttons are integrated into the touchpad and centrally connected to the motherboard via a first ribbon cable and a second ribbon cable, eliminating the need for additional scattered connection cables, reducing the risk of poor contact, and solving the problem of failure caused by scattered buttons;

[0036] This invention improves electromagnetic compatibility: the metal shielding cover completely covers the electronic components on the motherboard surface, effectively blocking external electromagnetic interference, ensuring stable signal transmission, avoiding interference with other electronic devices in the vehicle, and solving the problem of the lack of shielding structure on the motherboard.

[0037] This invention expands storage capacity: the motherboard has a reserved SATA interface, supporting optional 1T or 2T solid-state drives, meeting users' long-term, high-definition video storage needs and solving the problem of limited storage capacity;

[0038] This invention improves assembly efficiency: each component adopts a precise positioning snap-fit, plug-in, and fastening structure; the touch panel is pre-connected with ribbon cable; and the motherboard integrates all functional interfaces, reducing assembly wiring and adjustment steps, significantly improving production assembly efficiency, reducing labor costs, and solving the problem of low assembly efficiency.

[0039] This invention enhances installation stability: the support component on the back of the tail cover adapts to the vehicle mounting surface through an arc-shaped bracket, and is fixed by two sets of connecting seat bolts, ensuring that the recorder is stable after installation, avoiding displacement and loosening of internal components caused by vehicle vibration, and solving the problem of unstable installation.

[0050] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0051] The specific implementation of the present invention will be described in detail below with reference to specific embodiments.

[0052] like Figure 1-8 As shown, this embodiment of the invention provides an integrated anti-poor contact assembly structure for a vehicle recorder, including a touchpad 1, a middle frame 2, a tail cover 3, a sliding slider 4, a display screen 5, a main board 6, and a support component 7;

[0053] The back of the touchpad 1 is detachably snapped to the middle frame 2. The display screen 5 is embedded in the touchpad 1. The tail cover 3 is correspondingly snapped to the back of the middle frame 2. A sliding groove 32 is provided on one side of the tail cover 3. A speaker hole 31 is provided on the back of the tail cover 3. The movable slider 4 is slidably connected in the sliding groove 32. A speaker 33 is fixedly installed inside the tail cover 3. The speaker 33 is electrically connected to the speaker socket 66 on the motherboard 6 through a cable.

[0054] The touchpad 1 is fixedly connected to one end of the flexible first ribbon cable 11 and the second ribbon cable 12 respectively. The other ends of the first ribbon cable 11 and the second ribbon cable are fixedly connected to the plug-in structure 13. The plug-in structure 13 is detachably plugged into the back of the motherboard 6 and electrically connected to the ribbon cable interface 64 of the motherboard 6. The motherboard 6 is adapted to be installed in the placement slot 21 provided inside the middle frame 2. The surface of the motherboard 6 is electrically connected to the button battery structure 61, the TF memory card slot 62, the USB flash drive slot 63, and the reserved SATA interface 65. The surface of the motherboard 6 is fixedly covered with a shielding cover 67. A heat sink 68 is fixedly connected to the outside of the shielding cover 67. The support 7 is detachably fixedly connected to the middle area of ​​the back of the tail cover 3.

[0055] In this embodiment, the touchpad 1, mid-frame 2, and tail cover 3 adopt a layered snap-fit / fastening assembly method to ensure accurate positioning and stable connection of each component, reducing adjustment steps during assembly; the display screen 5 is embedded in the touchpad 1, avoiding the connection loosening problem caused by traditional external installation; the first ribbon cable 11 and the second ribbon cable 12 adopt a flexible design, and are centrally connected to the motherboard 6 with the plug-in structure 13, replacing the traditional distributed wiring, reducing the number of connecting wires, and reducing the risk of poor contact; the motherboard 6 integrates multiple functional interfaces to realize centralized electrical connection of components such as the speaker 33 and storage devices, further simplifying the connection relationship; the combined design of the shielding cover 67 and the heat sink 68 solves the electromagnetic interference problem and improves heat dissipation efficiency; the movable slider 4 cooperates with the slide groove 32 to achieve hidden protection of the interface, and the support component 7 enhances the overall installation stability. All structures work together to form an integrated system that prevents poor contact and achieves efficient assembly.

[0056] Specifically, the support component 7 includes an arc-shaped support plate and two sets of symmetrically arranged connecting seats. The connecting seats are detachably connected to the threaded holes pre-set on the back of the tail cover 3 via bolts. The arc-shaped support plate and the connecting seats are integrally formed.

[0057] In this embodiment, the support member 7 is designed with an integral arc-shaped support plate and a connecting seat. The arc-shaped support plate can adapt to the curvature of the vehicle mounting surface to improve the fit. The two sets of symmetrical connecting seats are fixed to the tail cover 3 with bolts to ensure a firm connection. At the same time, the detachable design facilitates later maintenance and replacement, effectively solving the problem of easy displacement after installation of traditional recorders.

[0058] Specifically, the first ribbon cable 11 and the second ribbon cable 12 are FFC flexible ribbon cables, and the plug-in structure 13 is equipped with a limit buckle, which is adapted to and connected to the card slot preset on the back of the motherboard 6.

[0059] In this embodiment, the first ribbon cable 11 and the second ribbon cable 12 are FFC flexible ribbon cables, which have the characteristics of good flexibility and stable transmission. They are adapted to the assembly angle between various components and avoid poor contact caused by wiring bends. The limiting buckle of the plug-in structure 13 is adapted to the slot of the motherboard 6 to achieve secondary fixation after plugging in, prevent the plugging from loosening due to vehicle vibration, and further improve the connection reliability.

[0060] Specifically, a through slot is provided at the bottom of the placement slot 21 of the middle frame 2.

[0061] In this embodiment, the through groove at the bottom of the middle frame 2 placement slot 21 is used to avoid and adapt to the plug-in structure 13, ensuring that the motherboard 6 and the plug-in structure 13 are connected without obstruction and with accurate positioning, ensuring a smooth plug-in process and improving assembly efficiency.

[0062] Specifically, the shield 67 is made of metal and is fixed to the surface of the motherboard 6 by welding or bolts.

[0063] In this embodiment, the metal shielding cover 67 has a good electromagnetic shielding effect, which can block external electromagnetic signals from interfering with the electronic components of the motherboard 6 and ensure stable signal transmission; the welding or bolt fixing method ensures that the shielding cover 67 is firmly connected to the motherboard 6, avoiding displacement or detachment caused by vehicle vibration.

[0064] Specifically, the heat sink 68 is an aluminum heat sink with multiple heat dissipation fins on its surface, and is attached and fixed to the shielding cover 67 by thermal grease.

[0065] In this embodiment, the aluminum heat sink 68 has high thermal conductivity due to its aluminum material. Combined with the heat dissipation fins on its surface, it can significantly increase the heat dissipation area and quickly conduct the heat generated by the motherboard 6. The use of thermal grease enhances the fit between the heat sink 68 and the shielding cover 67, improves the heat conduction efficiency, and effectively solves the problem of insufficient heat dissipation in traditional recorders.

[0066] Specifically, the TF memory card slot 62 and the USB flash drive slot 63 are hidden structures with their openings facing the slide groove 32. When the slider 4 is slid to the closed position, it completely covers the slots.

[0067] In this embodiment, the hidden TF memory card slot 62 and USB flash drive slot 63 have their openings facing the slide groove 32. When the sliding slider 4 is closed, it can completely cover the interface, preventing dust and debris from entering and causing poor contact, while also avoiding accidental contact that could cause the storage device to fall off. Users can slide the slider to insert and remove the storage device by hand without the need for tools, thus improving ease of use.

[0068] Specifically, the button battery structure 61 includes a battery holder and a removable button battery, with the battery holder fixed to the surface of the motherboard 6 by welding.

[0069] In this embodiment, the button battery structure 61 has its battery holder welded and fixed to the surface of the motherboard 6 to ensure a stable power supply connection. The button battery is detachably installed inside the battery holder, and the movable slider 4 on the outside serves to prevent dust and contact. When the battery life expires, the user can directly open the movable slider 4 to replace the battery without disassembling the entire device, thus solving the problem that traditional recorders cannot replace button batteries.

[0070] Specifically, the horn 33 is fixed in the pre-set mounting groove inside the tail cover 3 by a buckle or bolt, and the sound-producing surface of the horn 33 is set to correspond to the sound-emitting hole 31.

[0071] In this embodiment, the speaker 33 is fixed in the mounting groove of the tail cover 3 by a buckle or bolt to ensure that the speaker 33 is installed firmly and to avoid displacement or loosening of the wiring caused by vibration. The sound-emitting surface of the speaker 33 is set to correspond to the sound hole 31, which can reduce the loss in the sound transmission process and improve the sound pickup and sound production effect. At the same time, the cable is directly connected to the speaker socket 66 of the motherboard 6, replacing the traditional long-distance wiring and reducing the risk of poor contact.

[0072] Specifically, the inner side of the movable slider 4 is provided with a guide strip, the inner wall of the slide groove 32 is provided with a guide groove that matches the guide strip, and the outer side of the movable slider 4 is provided with anti-slip texture.

[0073] In this embodiment, the guide strip on the inner side of the movable slider 4 is adapted to the guide groove of the slide 32 to ensure smooth sliding of the slider and avoid jamming; the anti-slip texture on the outer side increases the friction during user operation, making it easier to slide the slider; the combination of the guide structure and the anti-slip design improves the ease of use and durability of the movable slider 4 and ensures the stable implementation of the interface protection function.

[0074] Working principle and usage process of this invention:

[0075] Assembly process:

[0076] Preparation before assembly: Connect one end of the first ribbon cable 11 and the second ribbon cable 12 to the preset interface of the touch panel 1 in advance to ensure a firm connection; fix the speaker 33 in the mounting groove inside the tail cover 3 with clips or bolts, and tidy up the connection wires of the speaker 33; check whether each component is intact and ensure that the plug structure 13, interface, etc. are undamaged;

[0077] Display assembly: Align the display 5 with the embedded mounting position inside the touchpad 1, slowly insert it and ensure that the display 5 and the touchpad 1 fit tightly without loosening or shifting, and complete the assembly of the display and the touchpad;

[0078] Mid-frame and touchpad assembly: With the back of the touchpad 1 (with the display screen 5 assembled) facing the mid-frame 2, align it with the snap-fit ​​structure of the mid-frame 2, and press firmly to make the touchpad 1 and the mid-frame 2 securely snap together, ensuring that the two are accurately positioned and without any wobbling;

[0079] Motherboard connection and installation: With the back of the motherboard 6 facing the plug-in structure 13, use the through slot at the bottom of the middle frame 2 placement slot 21 to avoid the plug-in structure 13, and slowly move the motherboard 6 so that the plug-in structure 13 and the ribbon cable interface 64 of the motherboard 6 are precisely plugged in. At the same time, press the limiting buckle of the plug-in structure 13 to make it engage and fix it with the slot on the back of the motherboard 6; continue to move the motherboard 6 until it is completely placed into the placement slot 21, ensuring that the motherboard 6 is installed firmly and has no room for displacement.

[0080] Tail cover assembly: Lead out the connecting wire of the speaker 33 inside the tail cover 3, align it with the speaker socket 66 on the main board 6, insert the connecting wire plug into the speaker socket 66 and ensure a stable electrical connection; then align the tail cover 3 with the back of the middle frame 2, and use the preset snap-fit ​​structure or bolts to firmly fasten the tail cover 3 to the middle frame 2, ensuring that the tail cover 3 is installed flat and without looseness;

[0081] Installation of the movable slider and support: Align the guide strip of the movable slider 4 with the slide groove 32 of the tail cover 3, and slowly slide it into the slide groove 32 from one end to ensure that the slider slides smoothly without jamming; align the connecting seat of the support 7 with the threaded hole in the middle area of ​​the back of the tail cover 3, and fix the support 7 to the back of the tail cover 3 detachably with bolts to complete the entire assembly process.

[0082] Workflow:

[0083] Equipment installation: Secure the assembled vehicle recorder to the preset position on the vehicle using the support component 7. Adjust the arc-shaped bracket of the support component 7 to ensure it fits tightly against the mounting surface. Tighten the bolts to ensure a stable installation and prevent displacement caused by vehicle vibration.

[0084] Power supply: The button battery structure 61 on the motherboard 6 provides basic power for the device to record time, ensuring that the device can still record time accurately after power failure; at the same time, the device can be connected to an external power supply or vehicle power supply system to provide power support for the overall operation.

[0085] Storage function usage: Slide the slider 4 to expose the TF memory card slot 62 and the USB flash drive slot 63. Users can manually insert the TF memory card or USB flash drive into the corresponding slot to store data such as videos and pictures. When a large capacity storage is required, a solid-state drive can be connected through the reserved SATA interface 65 to expand the storage capacity.

[0086] Functional Operation: The touchpad 1 receives the user's touch operation commands and transmits them to the motherboard 6 via the first ribbon cable 11. After processing, the motherboard 6 controls the display screen 5 to display relevant information. The speaker 33 achieves sound pickup or sound emission through the speaker hole 31. The sound pickup signal is transmitted to the motherboard 6 for processing via a cable to ensure audio acquisition effect. The heat generated by the motherboard 6 during operation is conducted to the heat sink 68 on the outside through the shielding cover 67 on the surface. The heat sink 68 dissipates the heat into the air through the heat dissipation fins to ensure that the motherboard 6 operates at a suitable temperature. The shielding cover 67 also blocks external electromagnetic interference to ensure the stability of the electronic components and signal transmission of the motherboard 6.

[0087] Maintenance and Replacement: When it is necessary to replace the TF memory card, USB flash drive or solid-state drive, the sliding slider 4 can be used to insert or remove it by hand; when the button battery is depleted, the sliding slider 4 on the outside of the battery holder can be opened to replace the button battery; when the device malfunctions and requires maintenance, the connection structure between the tail cover 3 and the middle frame 2 can be disassembled, and the components can be separated for inspection without disassembling a large number of connecting wires, making maintenance convenient.

[0088] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
