[0016] This section will describe in detail the specific embodiments of the present invention. The preferred embodiments of the present invention are shown in the accompanying drawings. The purpose of the accompanying drawings is to supplement the description of the text part of the specification with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present invention, but it should not be understood as a limitation on the scope of protection of the present invention.

[0017] Reference Figure 1-5 , an embodiment of the present invention provides a vehicle-mounted module table frame that is easy to install and disassemble, which includes: an installation frame 1, a circuit board fixing frame 2, a heat dissipation frame 3, and a display screen fixing frame 4 are arranged inside the installation frame 1, the circuit board fixing frame 2 is composed of a frame and a plurality of long rods, the long strips are fixedly connected to the inner wall of the frame, and the thickness of the long rods is less than the thickness of the frame, when the table frame is used, the circuit board contacts the upper surface of the long rods, and the above components cooperate with each other to separate different components of the vehicle-mounted module and improve the orderliness inside the table frame, the left and right surfaces of the circuit board fixing frame 2 and the left and right walls of the installation frame 1 are respectively provided with spherical clamping blocks 13 and contoured grooves 17, the spherical clamping blocks 13 are located inside the contoured grooves 17, and the spherical clamping blocks 13 cooperate with the contoured grooves 17 to increase the stability of the circuit board fixing frame 2 after entering the interior of the installation frame 1, and the surface of the display screen fixing frame 4 is rotatably connected to a lifting handle 18, which is clamped with the surface of the installation frame 1, and the lifting handle 18 is used to increase the force point of the display screen fixing frame 4.

[0018] Specifically, when using the watch frame to fix the vehicle-mounted module, the circuit board and display screen of the vehicle-mounted module are directly fixed on the surfaces of the circuit board fixing frame 2 and the display screen fixing frame 4, and then the circuit board fixing frame 2, the heat dissipation frame 3, and the display screen fixing frame 4 are pressed into the interior of the installation frame 1 in turn. In the process of pressing down the circuit board fixing frame 2, it is affected by the arc structure of the spherical block 13, and the resistance encountered by the circuit board fixing frame 2 when being pressed down is reduced. When it is necessary to separate the watch frame to inspect the vehicle-mounted module, since the surface of the display screen fixing frame 4 is smooth and there are fewer force points, the lifting handle 18 can be directly unfolded to directly extract the display screen fixing frame 4.

[0019] The upper surfaces of the front and rear walls of the heat dissipation frame 3 are provided with positioning grooves 5. The heat dissipation frame 3 is made of common heat dissipation materials and is used to concentrate the heat inside the meter frame. A hot-melt adhesive sheet 11 is provided inside the positioning groove 5. The hot-melt adhesive sheet 11 is in contact with the power cord of the vehicle-mounted mold. The hot-melt adhesive sheet 11 is made of plastic, and the front and rear ends of the hot-melt adhesive sheet 11 are bent to enter the interior of the positioning groove 5. A cutting opening 12 is provided on the surface of the hot-melt adhesive sheet 11. When the meter frame is used, the upper end of the power cord passes through the cutting opening 12 and extends to the top of the heat dissipation frame 3. The hot-melt adhesive sheet 11 is made of insulating plastic material and is used to limit the range of movement of the power cord, thereby improving the orderliness inside the meter frame.

[0020] Specifically, in the process of fixing the vehicle-mounted module using the frame, the two ends of the hot-melt adhesive sheet 11 are bent and the bent ends of the hot-melt adhesive sheet 11 are pressed into the interior of the positioning groove 5, and then a cutting tool is used to add a cutting opening 12 on the surface of the hot-melt adhesive sheet 11. At this time, the power cord connected to the circuit board can be passed through the cutting opening 12 and pulled toward the top of the heat dissipation frame 3. At the same time, after the power cord passes through the cutting opening 12, the hot-melt adhesive sheet 11 is added into the interior of the positioning groove 5, and the hot-melt adhesive sheet 11 is fixed inside the positioning groove 5 by using the hot-melt characteristics.

[0021] The lower inner wall of the mounting frame 1, the upper surfaces of the circuit board fixing frame 2 and the heat dissipation frame 3 are respectively fixedly connected with a single-hole receiving tube 6 and a double-hole receiving tube 7. The lower surfaces of the circuit board fixing frame 2, the heat dissipation frame 3 and the display screen fixing frame 4 are all fixedly connected with a socket rod 8. Multiple socket rods 8 are respectively located inside the single-hole receiving tube 6 and the double-hole receiving tube 7. The socket rods 8 cooperate with the single-hole receiving tube 6 and the double-hole receiving tube 7 to utilize the socket structure to integrate the mounting frame 1, the circuit board fixing frame 2, the heat dissipation frame 3 and the display screen fixing frame 4. The lower surface of the socket rod 8 is fixedly connected with a rubber pad 14. The rubber pads 14 on the lower surfaces of the multiple socket rods 8 are in contact with the inner walls of the single-hole receiving tube 6 and the double-hole receiving tube 7 respectively. The rubber pads 14 reduce the negative effects caused by the collision between the socket rod 8 and the receiving tube.

[0022] Specifically, after the circuit board, display screen, and power cord are installed, the circuit board fixing frame 2, the heat dissipation frame 3, and the display screen fixing frame 4 are pressed into the interior of the installation frame 1 in sequence. During the process of the circuit board fixing frame 2, the heat dissipation frame 3, and the display screen fixing frame 4 entering the interior of the installation frame 1, the socket rod 8 enters the interior of the storage tube to limit the range of movement of the circuit board fixing frame 2, the heat dissipation frame 3, and the display screen fixing frame 4 inside the installation frame 1.

[0023] A mounting cavity 15 is provided on the side surface of the socket rod 8, and a spring limiter 16 is fixedly connected to the inside of the mounting cavity 15. The spring limiter 16 is composed of a support spring 9 and a spherical block 10. Among the multiple spring limiters 16, the end of the spherical block 10 away from the inside of the mounting cavity 15 protrudes from the through holes on the side surfaces of the single-hole receiving tube 6 and the double-hole receiving tube 7. The two ends of the support spring 9 are fixedly connected to the inner wall of the mounting cavity 15 and the surface of the spherical block 10 respectively, and the diameter of the support spring 9 is smaller than the diameter of the mounting cavity 15. The diameter and depth of the mounting cavity 15 are greater than the diameter of the spherical block 10 and the length of the support spring 9 after compression. The support spring 9 and the spherical block 10 are both located inside the mounting cavity 15. The spring limiter 16 is used to increase the resistance encountered by the socket rod 8 after entering the inside of the receiving tube, thereby improving the stability of the socket rod 8.

[0024] Specifically, when the socket rod 8 enters the storage tube, the spherical block 10 is affected by the inner wall of the storage tube and is pressed into the interior of the installation cavity 15. When the spherical block 10 passes through the through hole on the surface of the storage tube, the spherical block 10 is affected by the support spring 9 and is ejected from the through hole on the surface of the storage tube, thereby preventing the components of the watch frame from sliding up and down due to the inertia of the bumps. At the same time, the spherical block 10 protruding from the through hole realizes the integration of the display screen fixing frame 4, the heat dissipation frame 3, and the circuit board fixing frame 2, so that in the process of lifting the display screen fixing frame 4, the heat dissipation frame 3 and the circuit board fixing frame 2 are driven out of the installation frame 1, thereby achieving the purpose of quickly unfolding the watch frame.

[0025] Working principle: When using the table frame to fix the vehicle-mounted module, first fix the circuit board and the display screen on the surface of the circuit board fixing frame 2 and the display screen fixing frame 4, then press the circuit board fixing frame 2 into the interior of the installation frame 1 so that the socket rod 8 and the spherical block 13 enter the single-hole storage tube 6 and the contoured groove 17, then press down the heat dissipation frame 3 so that the heat dissipation frame 3 is clamped with the double-hole storage tube 7 on the upper surface of the circuit board fixing frame 2, and then connect the power cord to the circuit board. While pulling the power cord upward, select a hot melt adhesive sheet 11 of appropriate width, and use a cutting tool to add a cutting opening 12 on the surface of the hot melt adhesive sheet 11, pass the upper end of the power cord through the cutting opening 12 and extend above the heat dissipation frame 3, then press down the display screen fixing frame 4 to complete the fixing of the vehicle-mounted module. When the vehicle-mounted module needs to be inspected, directly use the lifting handle 18 to lift the display screen fixing frame 4. Since the display screen fixing frame 4 and the heat dissipation frame 3 are subjected to the same friction force, when the pulling force is greater than the friction force applied to the display screen fixing frame 4, the heat dissipation frame 3 is synchronously driven up, and at this time the connection point of the power cord is completely exposed.

[0026] The embodiments of the present invention are described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Various changes can be made within the scope of knowledge possessed by ordinary technicians in the technical field without departing from the scope of the present invention.
