Description

Technical Field

[0001] This invention belongs to the field of vehicle-mounted electronic equipment installation, and relates to the design technology for rapid installation, reliable locking, and simultaneous power supply and multi-channel data communication of portable rugged tablets inside vehicles. Specifically, it relates to a device for rapid locking and multi-functional communication connection of a portable tablet in a vehicle. Background Technology

[0002] With the rapid development of intelligent cockpits and in-vehicle information systems, ruggedized portable tablets have been widely used in special vehicles, engineering vehicles, police / military vehicles, and logistics transportation for critical tasks such as navigation, mission scheduling, video surveillance, and human-machine interaction. In mobile operation scenarios such as UAV ground control, emergency command, and field exploration, operators often need to hold a tablet outside the vehicle to perform flight control, real-time image transmission, or situational awareness tasks; after the mission is completed, the tablet is returned to the vehicle for charging, data synchronization, or standby, forming a typical "vehicle-machine collaborative" working mode.

[0003] Such applications pose a dual challenge to the in-vehicle installation of tablets: on the one hand, tablets need to be frequently disassembled and reassembled, requiring the installation structure to support rapid deployment and one-handed handling; on the other hand, while the vehicle is in motion, it is essential to ensure that the tablet is securely fixed and can continuously provide stable power supply and multi-channel data communication, including high-speed data upload, high-definition video transmission, and device status feedback.

[0004] However, the current mainstream practice is still to place the tablet in a drawer or storage compartment under the dashboard and manually connect it to the vehicle's interface via USB or Type-C data cable. This method has the following obvious drawbacks:

[0005] (1) Each time you need to access the device, you need to plug and unplug the cable, which is cumbersome and makes it impossible to achieve the quick scene switching of "place and lock, take out and use". (2) Ordinary cable interfaces are prone to loosening or even falling off under vehicle vibration, resulting in power outages or communication failures; (3) It can only support a single function (such as charging or low-speed data), and it is difficult to meet the multi-channel integrated transmission requirements of power supply, control signals and high-definition video at the same time. (4) The drawer lacks a dedicated limiting structure, making the flat panel prone to sliding and collision, which poses a risk of equipment damage; (5) It does not support one-handed operation, which seriously affects the mission response efficiency during emergency deployment or rapid relocation.

[0006] Although some vehicle mounts on the market already have mechanical clamping capabilities, their electrical connections still rely on external cables, failing to achieve simultaneous integrated docking of mechanical locking and multi-functional communication. Current technology lacks a rapid docking device specifically designed for high-frequency, high-reliability mobile operations that can automatically establish a composite connection path including power, data, and video while ensuring structural stability. Summary of the Invention

[0007] To address the technical problems of existing vehicle-mounted portable tablets during storage and use, such as unstable fixation, reliance on external cables for electrical connections, cumbersome operation, and inability to quickly switch between task scenarios, and to meet the comprehensive needs of cutting-edge application scenarios such as drone control for efficient human-machine collaboration, seamless task switching, and adaptability to the vehicle environment, this invention discloses a device for quick locking and multi-functional communication connection of a vehicle-mounted portable tablet. The device includes a portable tablet, a fixed base, and a locking mechanism.

[0008] Specifically, the portable tablet has locking and guiding parts symmetrically arranged on both sides of its body, and an electrical contact point group is provided in the middle of its bottom surface. A fixed base is installed inside a mobile vehicle. The fixed base is provided with a guide positioning component, an elastic contact component, and a locking mechanism mounting area. The guide positioning component cooperates with the guide mating part. A locking mechanism is installed in the locking mechanism installation area, including an operating component, a transmission component, and a locking component. The operating component drives the transmission component, causing the transmission component to work in conjunction with the locking component to switch the locking component between an unlocked position and a locked position. When the portable tablet is placed on the fixed base, the guide positioning member is inserted into the guide mating part for initial positioning. Then, the locking member is embedded into the locking mating part at the locking position for mechanical locking. At the same time, the elastic contact component establishes an electrical connection with the electrical contact point group to realize power supply and data communication.

[0009] Furthermore, the portable tablet is also provided with a locking threaded hole, and the operating component is a tightening screw, the screw section of which passes through the fixed base and is threadedly engaged with the locking threaded hole, and its front end forms a thrust end face.

[0010] Furthermore, the transmission component is a shift fork rod, which is hinged to the fixed base by a first fixing pin. One end of the shift fork rod abuts against the thrust end face of the operating component, and the other end is provided with a moving shaft.

[0011] Furthermore, the locking element is a locking rod, which is hinged to the fixed base by a second fixing pin; The locking rod is provided with a guide groove and a buckle part. The moving shaft is slidably engaged in the guide groove. When the buckle part is in the locked position, it is embedded in the locking engagement part.

[0012] Furthermore, the axis of the second fixing pin is perpendicular to the direction of movement of the moving vehicle to enhance the locking member's ability to resist vibrations in that direction.

[0013] Furthermore, the guide positioning element is a tapered pin, and the guide mating part is a tapered groove that matches the guide positioning element, used to achieve self-centering guidance.

[0014] Furthermore, the elastic contact assembly includes an elastic contact pin, a floating bracket, and a compression spring. The elastic contact pin is fixed on the floating bracket, and the floating bracket is pre-compressed into the fixed base by the compression spring to provide constant contact pressure after the plate is in place.

[0015] Furthermore, the electrical contact point group and the elastic contact component constitute a composite electrical connection interface, integrating DC power supply, USB data signal and video transmission channel.

[0016] Furthermore, the fixed base is provided with a waist-shaped mounting hole for adjusting its mounting position on the operating table of the mobile vehicle.

[0017] Furthermore, when the operating component is in the unlocked state, the locking component disengages from the locking engagement part, allowing the user to vertically remove the portable tablet with one hand.

[0018] This invention achieves rapid installation and reliable connection of a portable tablet on a mobile vehicle through an integrated mechanical-electrical co-design. Compared to existing technologies, this device has at least the following advantages: (1) Ease of operation: Users only need to place the tablet on the fixed base and tighten the operating parts to simultaneously complete the mechanical locking and electrical connection establishment without the need to plug or unplug cables; (2) Connection reliability: During the tightening of the operating parts, the transmission mechanism synchronously drives the locking rod to move, so that its buckle part is embedded in the locking engagement part of the plate, thereby achieving a firm mechanical lock; This locking structure effectively suppresses the displacement of the plate caused by vibration during the operation of the mobile vehicle, thereby ensuring continuous and stable contact between the elastic contact pin and the quick-connect contact point; (3) Functional integration: By connecting the elastic pins on the fixed base with the quick-connect contact group on the bottom of the tablet, DC power supply, USB data communication and high-definition video signal transmission can be realized at one time, meeting the needs of multi-channel composite communication; (4) Environmental adaptability: The hinge axis of the locking mechanism is perpendicular to the main movement direction of the vehicle. Combined with the floating preloaded contact pin design, it significantly improves the device's anti-interference ability in high vibration environment and avoids communication interruption or power supply failure caused by mechanical loosening.

[0026] This invention discloses a device for quick locking and multi-functional communication connection of a vehicle-mounted portable tablet, such as... Figure 1 As shown, the device includes a portable tablet 10, a fixed base 20, and a locking mechanism 30.

[0027] Specifically, such as Figures 1 to 3 As shown, the portable tablet 10 has locking mating parts 11 and guiding mating parts 12 symmetrically arranged on both sides of its main body, and an electrical connection contact point group 14 is provided in the center of its bottom surface. The portable tablet 10 can be an industrial-grade ruggedized tablet, the locking mating parts 11 can be rectangular, the guiding mating parts 12 can be designed as conical, and the number of contacts in the electrical connection contact point group 14 can be designed as 6 gold-plated contacts. The tablet can be designed to transmit +12V, GND, USB D+ / D- and MIPI video signals.

[0028] The fixed base 20 is installed inside the mobile vehicle. The fixed base 20 is provided with a guide positioning component 21, an elastic contact component 22 and a locking mechanism mounting area. The guide positioning component 21 cooperates with the guide mating part 12.

[0029] The locking mechanism 30 is installed in the locking mechanism installation area and includes an operating member 31, a transmission member 32 and a locking member 33. The operating member 31 drives the transmission member 32, so that the transmission member 32 is linked to the locking member 33, and the locking member 33 is switched between the unlocked position and the locked position.

[0030] like Figure 4 As shown, when the portable tablet 10 is placed on the fixed base 20, the guide positioning member 21 is inserted into the guide mating part 12 for initial positioning. Then, the locking member 33 is embedded in the locking mating part 11 at the locking position for mechanical locking. At the same time, the elastic contact component 22 establishes an electrical connection with the electrical contact point group 14 to realize power supply and data communication.

[0031] In one embodiment, such as Figure 1 , Figure 2 , Figure 4 and Figure 5 As shown, the portable tablet 10 is also provided with a locking threaded hole 13. The operating component 31 is a tightening screw, the screw section of which passes through the fixed base 20 and is threadedly engaged with the locking threaded hole 13, and its front end forms a thrust end face. The transmission component 32 is a shift fork rod, which is hinged to the fixed base 20 by a first fixing pin 34. One end of the shift fork rod abuts against the thrust end face of the operating component 31, and the other end is provided with a moving shaft 35. The locking component 33 is a locking rod, which is hinged to the fixed base 20 by a second fixing pin 36. The locking rod is provided with a guide groove 37 and a latching part. The moving shaft 35 is slidably engaged in the guide groove 37, and the latching part is embedded in the locking engagement part 11 when in the locked position.

[0032] For example, the operating component 31 can be designed as a screw with a handle, the screw section of which passes through the base and is threaded into the locking threaded hole 13 on the plate, with the front end forming a planar thrust end face. The transmission component 32 is an L-shaped shift fork rod, hinged to the base by the first fixing pin 34, with one end abutting the thrust end face and the other end having a moving shaft 35. The locking component 33 is a bent-arm locking rod, hinged to the base by the second fixing pin 36, with an elongated oval guide groove 37 on it, through which the moving shaft 35 passes; the free end forms a snap-fit ​​part that can be inserted into the locking engagement part 11.

[0033] Preferably, the axial direction of the second fixing pin 36 is perpendicular to the direction of movement of the moving vehicle, so as to enhance the ability of the locking member 33 to resist vibration in that direction.

[0034] In one embodiment, such as Figure 1 and Figure 2As shown, the portable flat plate 10 is also provided with a locking threaded hole 13. The operating component 31 is a tightening screw, the screw section of which passes through the fixed base 20 and is threadedly engaged with the locking threaded hole 13, and its front end forms a thrust end face.

[0035] Preferably, the guide positioning element 21 is a tapered pin, and the guide mating part 12 is a tapered groove that matches the guide positioning element 21, for achieving self-centering guidance.

[0036] In an embodiment where no figures are shown, the resilient contact assembly 22 includes a resilient stylus, a floating bracket, and a compression spring. The resilient stylus is fixed to the floating bracket, which is pre-compressed into the fixed base 20 by the compression spring to provide a constant contact pressure, such as 2N, after the plate is in place.

[0037] In one embodiment, the electrical contact point group 14 and the elastic contact component 22 constitute a composite electrical connection interface, integrating DC power supply, USB data signal and video transmission channel.

[0038] In one embodiment, such as Figure 3 As shown, the fixed base 20 is provided with a waist-shaped mounting hole 23 for adjusting its mounting position on the operating table of the mobile vehicle.

[0039] In one embodiment, such as Figure 5 As shown, when the operating member 31 is in the unlocked state, the locking member 33 disengages from the locking engagement part 11, and the user can vertically remove the portable tablet 10 with one hand.

[0040] When using, such as Figure 4 As shown, the user places the tablet vertically on the base, and the guide positioning member 21 is inserted into the guide mating part 12 to achieve initial positioning; tighten the operating member 31, and its thrust end face pushes the transmission member 32 to rotate, the moving shaft 35 slides in the guide groove 37, driving the locking member 33 to rotate around the second fixed pin 36, and the buckle part is embedded into the locking mating part 11 to complete the locking; at the same time, the contact pin and the contact group establish an electrical connection.

[0041] During disassembly, such as Figure 5 As shown, loosening the operating component 31 causes the locking component 33 to rotate, allowing the user to remove the flat plate vertically with one hand.

[0042] This invention achieves rapid installation and reliable connection of a portable tablet on a mobile vehicle through an integrated mechanical-electrical co-design. Compared to existing technologies, this device has at least the following advantages: (1) Ease of operation: Users only need to place the tablet on the fixed base and tighten the operating parts to simultaneously complete the mechanical locking and electrical connection establishment without the need to plug or unplug cables; (2) Connection reliability: During the tightening of the operating parts, the transmission mechanism synchronously drives the locking rod to move, so that its buckle part is embedded in the locking engagement part of the plate, thereby achieving a firm mechanical lock; This locking structure effectively suppresses the displacement of the plate caused by vibration during the operation of the mobile vehicle, thereby ensuring continuous and stable contact between the elastic contact pin and the quick-connect contact point; (3) Functional integration: By connecting the elastic pins on the fixed base with the quick-connect contact group on the bottom of the tablet, DC power supply, USB data communication and high-definition video signal transmission can be realized at one time, meeting the needs of multi-channel composite communication; (4) Environmental adaptability: The hinge axis of the locking mechanism is perpendicular to the main movement direction of the vehicle. Combined with the floating preloaded contact pin design, it significantly improves the device's anti-interference ability in high vibration environment and avoids communication interruption or power supply failure caused by mechanical loosening.
