DETAILED DESCRIPTION

[0039] In order to more clearly and completely illustrate the technical solution of the present invention, the present invention is further described below in conjunction with the accompanying drawings.

[0040] Please refer to Figure 1-Figure 8The present invention provides an intelligent automobile instrument that is easy to assemble, including a main body 1 and a fastening device 2. The main body 1 is the main body of the intelligent automobile instrument. The fastening device 2 is fixedly connected to the back of the main body 1. A circuit board is arranged in the main body 1. A data processing module 101, a first driving module 102, and a wireless transmission module 103 are arranged on the circuit board. The data processing module 101 is electrically connected to the first driving module 102 and the wireless transmission module 103 respectively. The data processing module 101 is used to issue corresponding operation instructions to the first driving module 102 according to the instructions of the wireless transmission module 103. The first driving module 102 is used to drive the fastening device 2 to operate. The fastening device 2 is electrically connected to the first driving module 102. The wireless transmission module 103 is used to receive external wireless control instructions, which can be instructions from a remote control or instructions from a corresponding mobile phone APP. After the wireless transmission module 103 receives the external wireless control instructions, the data processing module 101 issues corresponding operation instructions to the first driving module 102, so that the first driving module 102 drives the fastening device 2 to support external fixation or to retract and loosen the fixation.

[0041] In this embodiment, when the main body 1 is installed on the car, the main body 1 is placed in the installation groove of the original car instrument position at a suitable depth. After the conductive wire on the main body 1 is connected to the car and powered on, it can be wirelessly connected to the user's mobile phone through the wireless transmission module 103. The wireless transmission module 103 can be a Bluetooth module, a WiFi module, or an infrared receiving module. The infrared receiving module needs to be connected using a remote control. After using the mobile phone for wireless connection, the user can operate through the corresponding mobile phone APP to send wireless control instructions. After the wireless transmission module 103 receives the external wireless control instruction, the data processing module 101 issues the corresponding operation instruction to the first drive module 102, so that the first drive module 102 drives the fastening device 2 to support it externally to fix it to the outside. At this time, the main body 1 is installed. When disassembly is required, the corresponding mobile phone APP is also used to operate so that the first drive module 102 drives the fastening device 2 to retract, loosen and fix it for disassembly.

[0042] In this embodiment, the fastening device 2 includes a fixed shell 21, a double-rod motor 22, two sliding blocks 23, and an external support mechanism 24. The fixed shell 21 is fixedly connected to the back of the main body 1, and the double-rod motor 22 is fixedly connected inside the fixed shell 21. The two sliding blocks 23 are respectively connected to the left and right screw rods 221 of the double-rod motor 22 for transmission and are symmetrically arranged. The external support mechanism 24 is arranged around the inner side of the fixed shell 21 and is respectively connected to the two sliding blocks 23 for transmission. The double-rod motor 22 drives the two sliding blocks 23 to slide at the same time, which can drive the external support mechanism 24 to support and fix it externally or to retract and loosen it; the fixed shell 21 is fixedly connected to the back of the main body 1 by screw locking. After the main body 1 is placed at an appropriate depth in the slot of the original automobile instrument position, the first drive module 102 issues a forward rotation command to On the double-rod motor 22, the double-rod motor 22 rotates forward, and at this time the left and right screw rods 221 rotate forward, and at the same time drive the two sliding blocks 23 to slide toward the outside of the double-rod motor 22, and the outward sliding of the two sliding blocks 23 drives the external support mechanism 24 to be expanded outward relative to the fixed shell 21, so that the outer peripheral side of the external support mechanism 24 is abutted and fixed to the inner wall of the mounting groove of the original automobile instrument position, and finally the main body 1 is fixed; when disassembling, the first drive module 102 issues a reverse command to the double-rod motor 22, and the double-rod motor 22 reverses. At this time, the left and right screw rods 221 reverse, and at the same time drive the two sliding blocks 23 to slide toward the direction of the double-rod motor 22, and the inward sliding of the two sliding blocks 23 drives the external support mechanism 24 to be retracted relative to the fixed shell 21 to loosen the fixation.

[0043] In this embodiment, the outer support mechanism 24 includes an upper support component 241, a lower support component 242, a left support component 243, and a right support component 244. The upper support component 241, the lower support component 242, the left support component 243, and the right support component 244 are all slidably connected to the fixed shell 21. Four sliding grooves 211 are provided in the fixed shell 21. The upper support component 241, the lower support component 242, the left support component 243, and the right support component 244 correspond to the four sliding grooves 211 one by one and are slidably connected to the groove walls of the sliding grooves 211 respectively. One end of the upper support component 241 is symmetrically hinged to one side of the two sliding blocks 23, one end of the lower support component 242 is symmetrically hinged to the other side of the two sliding blocks 23, the left support component 243 is fixedly connected to one end of one sliding block 23, and the right support component 244 is fixedly connected to the other end of the other sliding block 23. One end is fixedly connected, and the double-rod motor 22 drives the two sliding blocks 23 to slide at the same time, and can drive the upper opening component 241, the lower opening component 242, the left opening component 243, and the right opening component 244 to slide at the same time; when the main body 1 needs to be fixed to the outside, the double-rod motor 22 rotates forward to make the two sliding blocks 23 slide outward, and the upper opening component 241, the lower opening component 242, the left opening component 243, and the right opening component 244 are simultaneously driven to slide outward, and relative to the fixed shell 21, they are stretched outward, so that the main body 1 is fixed; when the main body 1 needs to be disassembled, the double-rod motor 22 reverses to make the two sliding blocks 23 slide inward, and the upper opening component 241, the lower opening component 242, the left opening component 243, and the right opening component 244 are simultaneously driven to slide inward, and relative to the fixed shell 21, they are retracted inward.

[0044] In this embodiment, the upper opening component 241 includes two first connecting components 2411, a first support frame 2412, and a first pressing block 2413. One end of the two first connecting components 2411 is hinged to one side of the two sliding blocks 23, and the other end of the two first connecting components 2411 is hinged to the back of the first supporting frame 2412. The two first connecting components 2411 are symmetrically arranged, and the first supporting frame 2412 forms a longitudinal sliding connection with the fixed shell 21, and the first pressing block 2413 is fixedly connected to the other end of the first supporting frame 2412; since the width of the main body 1 is greater than the height, the length of the upper opening component 241 and the lower opening component 242 will be greater than the length of the left opening component 243 and the right opening component 244. Since the two screw rods 221 of the double-rod motor 22 can only be oriented in two symmetrical directions, the left and right directions are the best orientations. When the screw rod 221 drives the sliding block 23 to slide, the first connecting component 2411 cannot be directly pushed to The first support frame 2412 is slidably connected to the fixed shell 21, and the outward sliding of the sliding block 23 will cause the first connecting component 2411 to change the inclination angle, thereby pushing the first support frame 2412 outward, so that the first support frame 2412 pushes the first pressing block 2413 outward to abut against the upper and lower sides of the main body 1. The upper and lower sides of the main body 1 can be directly fixed to the outer wall of the installation groove, so that the main body 1 can balance the force. The first pressing block 2413 is an anti-skid structure made of rubber or silicone material, which is hollow and has a certain elasticity. It will elastically deform when subjected to extrusion force, and will form a tight fit after abutting against the groove wall of the installation groove to avoid accidental side sliding.

[0045] In this embodiment, the first connecting component 2411 includes a first connecting rod 24111 and a first pressure sensor 24112. One end of the first connecting rod 24111 is hinged to one side of the sliding block 23, and the other end of the first connecting rod 24111 is hinged to the back of the first support frame 2412. The first pressure sensor 24112 is used to detect the bending force value of the middle part of the first connecting rod 24111. The first pressure sensor 24112 is electrically connected to the data processing module 101. When the first support frame 2412 drives the first pressing block 2413 to abut outward, in order to ensure sufficient abutment force, the first pressure sensor 24112 is arranged on the first connecting rod 24111, and the first U-shaped portion 203 is arranged in the middle of the first connecting rod 24111. The first pressure sensor 24112 is installed in the first U-shaped portion 203. When the sliding block 23 slides outward and drives the first connecting rod 24111 to change the inclination angle and then pushes the first support frame 2412 to slide outward, the first connecting rod 24111 will produce a certain amount of elastic deformation, and the amount of its elastic deformation depends on the magnitude of the force of the first pressing block 2413 abutting against the inner wall of the installation groove. A force value that can be appropriately fixed is set as the detection threshold of the first pressure sensor 24112. After reaching the threshold, it indicates that the outer support of the upper support component 241 or the lower support component 241 is in place; a connecting column 24121 is provided on the back of the first support frame 2412, and a rotating hole 202 is provided at one end of the first connecting rod 24111. The connecting column 24121 passes through the rotating hole 202 to form a hinge.

[0046] In this embodiment, the left opening component 243 includes a second connecting component 2431 and an elastic pressing component 2432. One end of the second connecting component 2431 is fixedly connected to one end of the sliding block 23, and the other end of the second connecting component 2431 is fixedly connected to the back of the elastic pressing component 2432. The elastic pressing component 2432 forms a horizontal sliding connection with the fixed shell 21; the left opening component 243 has the same structure as the right opening component 244; when the sliding block 23 slides outward, the sliding block 23 pushes the second connecting component 2431 to move outward, thereby pushing the elastic pressing component 2432 to slide outward, so as to elastically abut against the inner wall of the mounting groove.

[0047] In this embodiment, the elastic pressing component 2432 includes a second support frame 24321, a plurality of elastic members 24322, and a second pressing block 24323. The back of the second support frame 24321 is fixedly connected to one end of the second connecting component 2431. The second support frame 24321 forms a transverse sliding connection with the fixed shell 21. The second support frame 24321 is provided with a sliding cavity 201. The plurality of elastic members 24322 are all accommodated in the sliding cavity 201. One end of the second pressing block 24323 is accommodated in the sliding cavity 201 and is slidably connected to the sliding cavity 201. One end of the elastic member 24322 abuts against the inner wall of the sliding cavity 201, and the other end of the elastic member 24322 abuts against the second pressing block 24323. When the sliding block 23 slides outward, The second connecting component 2431 pushes the second supporting frame 24321 to slide outward. After the second pressing block 24323 makes initial contact with the groove wall of the mounting groove, the double-rod motor 22 still needs to continue to rotate, thereby continuing to drive the sliding block 23 to slide outward, and then making the second supporting frame 24321 continue to slide outward, and the second supporting frame 24321 and the second pressing block 24323 together squeeze the multiple elastic members 24322, so that the elastic force of the multiple elastic members 24322 serves as the contact force applied by the second pressing block 24323 to the groove wall of the mounting groove, thereby improving the fixing effect and protecting the operation of the double-rod motor 22; the second pressing block 24323 is an anti-slip structure made of rubber or silicone material, which is used to improve the fixing force.

[0048] In this embodiment, the second connecting component 2431 includes a second connecting rod 24311 and a second pressure sensor 24312. One end of the second connecting rod 24311 is fixedly connected to one end of the sliding block 23, and the other end of the second connecting rod 24311 is fixedly connected to the back of the second support frame 24321. The second pressure sensor 24312 is used to detect the pressing force value of the middle part of the second connecting rod 24311. The second pressure sensor 24312 is electrically connected to the data processing module. In order to ensure that the elastic pressing component 2432 has sufficient abutment force, the second pressure sensor 24312 is set to detect the pressure exerted on the second connecting rod 24311. The middle part of the second connecting rod 24311 is provided with a second U-shaped portion 204. The second pressure sensor 24312 is used to detect the pressing force value of the middle part of the second connecting rod 24311. The second pressure sensor 24312 is electrically connected to the data processing module. The sensor 24312 is installed in the second U-shaped portion 204. When the sliding block 23 pushes the second connecting rod 24311 to move so that the second support frame 24321 slides outward and multiple elastic members 24322 are squeezed and the second pressing block 24323 abuts against the groove wall of the installation groove, the second connecting rod 24311 will produce a certain elastic deformation, and the elastic deformation site is concentrated in the second U-shaped portion 204. At this time, the second pressure sensor 24312 can detect the elastic deformation force of the second connecting rod 24311, and set a force value that can be properly fixed as the detection threshold of the second pressure sensor 24312. After reaching the threshold, it indicates that the external support of the left support component 241 or the right support component 241 is in place.

[0049] In this embodiment, the outer surface of the main body 1 is provided with a dashboard 11 and a ring light 12, and the ring light 12 is distributed around the outer peripheral side of the dashboard 11. The circuit board is provided with a second drive module 104, a vehicle speed collection module 105, and a data acquisition module 106. The second drive module 104, the vehicle speed collection module 105, and the data acquisition module 106 are all electrically connected to the data processing module 101. The second drive module 104 is electrically connected to the ring light 12. The second drive module 104 is used to issue corresponding operation instructions to the ring light 12. The vehicle speed collection module 105 is used to collect vehicle speed information of the dashboard 11 and feed it back to the data processing module 106. The data acquisition module 106 is used to obtain navigation road speed limit information in the mobile phone APP; when in use, the user needs to wirelessly connect to the mobile phone through the wireless transmission module 103, and then when the mobile phone uses the APP for navigation, the data acquisition module 106 will obtain the navigation road speed limit information in the mobile phone APP, and then mark it as the first speed information, and the speed collection module 106 will obtain the navigation road speed limit information in the mobile phone APP.

If the second speed information is greater than the first speed information, the ring light 12 turns on red to remind the user that the vehicle is speeding. If the second speed information is less than the first speed information, the ring light 12 does not turn on. If the driver has not started to slow down at this time, and the second speed information has exceeded 40% of the first speed information, the ring light 12 turns on red and flashes continuously at a time interval of 0.5s, thereby increasing the intensity of the reminder.

[0058] In summary, the easy-to-assemble intelligent automobile instrument and the control method thereof can quickly install and disassemble the automobile instrument, which is convenient and quick, and at the same time has a speeding reminder function, which is conducive to timely reminding the driver.

[0059] Of course, the present invention may have many other implementations. Based on this implementation, other implementations obtained by ordinary technicians in this field without any creative work are all within the scope of protection of the present invention.
