Of course, in the embodiment of the present invention, the elastic fixing module can adapt to vehicle-mounted communication devices of different thicknesses and lengths. However, after the card slot 402 enters the elastic fixing module, it is at least necessary to cause the elastic fixing module to be elastically compressed so that the elastic fixing module can be compressed and stored, thereby achieving the purpose of limiting fixation, and at the same time, it can also buffer the vibration of the vehicle-mounted communication device. When the vehicle-mounted communication device enters the elastic fixing module, the eccentric locking module is used to lock the other end of the vehicle-mounted communication device. In this way, the vehicle-mounted communication device is fixed.More specifically, in the present invention, the eccentric lock module is specifically designed, that is, the eccentric principle is adopted, and the eccentric buckle is driven by the knob shaft to perform planetary motion around the knob shaft 204 in the rotating groove 205. When the eccentric buckle 207 moves up and down in the planetary orbit, the hook 201 is driven to move up and down in the sliding groove 206 through the transverse groove 202. At the same time, the left and right movement directions in the planetary orbit of the eccentric buckle 207 move in the same direction in the transverse groove 202, and are limited by the transverse groove 202.

The rotating shaft includes a leaf spring and a leaf spring fixing member, one end of the leaf spring is fixedly connected to the lock body through the leaf spring fixing member, and the other end is fixedly connected to the fixed disk 1 through the leaf spring fixing member, in this way, when the hook 201 slides into the lock groove 401, a stopping force between the hook 201 and the hook 201 is provided, and when the hook 201 slides out of the lock groove 401, the lock body is rotated back to its original position under the action of elastic force. In a preferred embodiment of the present invention, the slide groove 206 is a U-shaped structure, in this way, the lateral sides of the hook 201 are limited, and at the same time, the movement of the hook 201 is guided to ensure the stability of the device when it is working. Of course, as a preferred solution of this embodiment, a sliding groove is also provided on the slide groove 206, and correspondingly, a slider is provided on the hook. The slider and the sliding groove are arranged in coordination so that the hook 201 moves relative to the lock body 203 along the sliding groove. In this way, the longitudinal position of the hook is further limited, and the accuracy of the device is further improved.

[0039] In a preferred embodiment of the present invention, the eccentric lock module further includes a knob 208, the knob 208 is fixedly connected to the knob shaft 204, and the knob 208 is coaxially arranged with the knob shaft 204, one end of the eccentric buckle 207 is fixedly arranged with the knob 208, and the knob 208 is eccentrically arranged with the eccentric buckle 207. The eccentric lock module further includes a handle 209 and a handle stopper, the handle 209 is arranged on the knob 208, and the handle stopper is used to limit the rotation of the handle 209 when the hook 201 slides into the lock slot 401. The handle limiter includes a lock hole provided on the lock body 203 and a lock rod provided on the handle 209, and the handle 209 is rotatably connected to the knob 208. When the hook 201 slides into the lock slot 401 to lock, the handle 209 is pushed along the axis of the knob 208 so that the lock rod enters the lock hole to limit the twisting of the handle 209. As a preferred solution of this embodiment, the knob 208 can directly use a knob motor, and the power output shaft of the knob motor is fixedly connected to the knob shaft. At the same time, the stroke of the knob motor is set, so that the knob motor can make the hook 201 slide into the lock slot 401 and lock within a working stroke range. Of course, on the basis of the above embodiment, a thickness sensor is set to identify the thickness of the vehicle-mounted communication device, and the knob motor adjusts the working stroke according to the thickness to avoid the hook 201 moving too much downward to cause pressure damage to the equipment and devices. As a preferred solution of this embodiment, the central angle of the rotating groove 205 is 45°, that is, twisting the knob handle to drive the knob to rotate 45° clockwise can slide the hook 201 into the locking groove 401 and lock it.

[0040] In one embodiment of the present invention, the elastic fixing module includes a card block 3, which includes a horizontal plate and a vertical plate that are integrally formed and arranged vertically, the horizontal plate is arranged parallel to the fixing plate 1, a first spring piece 301 is fixedly arranged on the vertical plate, and a second spring piece 302 is fixedly arranged on the horizontal plate.

[0041] like Figure 5As shown, as a preferred embodiment of the present invention, in order to improve the adaptability of the device, that is, for different types of vehicle-mounted communication equipment, the present invention also provides a transverse elastic limit adjustment member, which is arranged on the limit slide plate, that is, each limit slide plate is provided with a transverse elastic limit adjustment member, and the two transverse elastic limit adjustment members are arranged opposite to each other. In this embodiment, the transverse elastic limit adjustment member includes a limit plate 101, a fixed plate 107 and an elastic adjustment component arranged therebetween, and both adjustment components are hinged to the limit plate 101 through a hinge 102 arranged on the limit plate 101. The two adjustment components are symmetrically arranged about the hinge 102. In this embodiment, the fixed plate 107 can be directly replaced by a limit slide plate. An adjustment groove is provided on the fixed plate 107. The lateral elastic limit adjustment member includes an elastic adjustment rod 103, an adjustment slider 104, an adjustment spring 105 and an adjustment limit member 106 which are connected in sequence, wherein the adjustment limit member 106 is arranged at the end of the adjustment groove, the adjustment slider 104 is movably arranged in the adjustment groove, and the elastic adjustment rod 103 is rotatably connected to the adjustment slider 104. In this way, when pressure is applied to the limit plate 101, the limit plate 101 applies an extrusion force through the elastic adjustment rod 103, and the extrusion force squeezes the adjustment spring 105 through the adjustment slider 104, so that the adjustment spring 105 is compressed and stores energy, thereby adjusting the distance between the two relatively set limit plates 101, so as to be practical for different models of vehicle-mounted communication equipment.

[0042] In one embodiment of the present invention, the fixing plate 1 is further provided with an inclined entry platform 6, and the inclined entry platform 6 is arranged on a side where the eccentric locking module is arranged.

[0043] like Figure 7 According to another aspect of the present invention, a method for installing a vehicle-mounted communication device is provided, comprising the following steps:

[0044] Step 1: Pass the fixed connector through the mounting countersunk hole 5 to fix the fixed plate 1 to the vehicle body. Specifically, in this step, when the fixed connector is connected to the mounting countersunk hole 5, the height of the fixed connector shall not exceed the upper surface of the fixed plate 1 to avoid affecting the pushing-in of the vehicle-mounted communication device 4 and also avoid crushing the vehicle-mounted communication device, so that the vehicle-mounted communication device is installed more stably.

[0045] Step 2, place the eccentric lock module horizontally, then place the vehicle-mounted communication device 4 on the fixed disk 1, and push the vehicle-mounted communication device 4 to slide along the limiting slide until the card slot 402 is connected to the elastic fixing module. At this time, the vehicle-mounted communication device 4 is placed parallel to the fixed disk 1. More specifically, in this step, the card slot 402 of the vehicle-mounted communication device 4 is pushed, and the card slot 402 first compresses the second spring piece 302, so that the second spring piece 302 is compressed and stored in the vertical direction, and then the card slot 402 compresses the first spring piece 301 in the longitudinal direction, so that the first spring piece 301 is compressed and stored in the longitudinal direction. When the spring piece stores energy, the spring piece reacts to the card slot 402 to fix the card slot 402.

[0046] Step 3: Rotate the eccentric buckle 207 so that the hook 201 moves to the farthest distance from the fixed disk 1, turn the eccentric lock buckle module to a vertical state, rotate the eccentric buckle 207, and the eccentric buckle 207 performs planetary motion around the knob shaft 204 in the rotating groove 205. At the same time, the eccentric buckle 207 performs horizontal motion in the transverse groove 202, so as to drive the hook 201 to move downward along the axial direction of the lock body 203 until the hook 201 slides into the lock groove 401, thereby fixing and locking the vehicle-mounted communication device 4. In this step, the eccentric buckle is driven to perform planetary motion around the knob shaft 204 in the rotating groove 205 by the knob shaft. When the eccentric buckle 207 moves up and down in the planetary track, the hook 201 is driven to move up and down in the slide groove 206 by the transverse groove 202. At the same time, the left and right movement directions in the planetary track of the eccentric buckle 207 move in the same direction in the transverse groove 202, and are limited by the transverse groove 202.

[0047] Step four, when it is necessary to unlock the vehicle-mounted communication device 4, rotate the eccentric buckle 207, and the eccentric buckle 207 performs planetary motion around the knob shaft 204 in the rotating groove 205. At the same time, the eccentric buckle 207 performs horizontal motion in the transverse groove 202 to drive the hook 201 to move upward along the axial direction of the lock body 203 until the hook 201 slides out of the lock groove 401, thereby unlocking the vehicle-mounted communication device 4.

[0048] In one embodiment of the present invention, a fixing device for vehicle-mounted communication equipment includes a fixing plate, a countersunk mounting hole is provided on the fixing plate, and the countersunk mounting hole can pre-fix the fixing plate to a certain position on the vehicle by bolts, a clamping block is provided at the rear end of the fixing plate, a spring is provided on the clamping block, a spring is contained in the spring, a locking hook is provided at the front end of the fixing plate, the locking hook is connected to the fixing plate through a knob shaft, a lock body is provided on the knob shaft, a hook is provided on the lock body, the hook can slide up and down on the lock body, a knob is provided on the lock body, a handle is provided on the knob, an eccentric buckle is provided on the rotating knob, and the eccentric buckle is connected to the hook through an arc groove. More specifically, the device includes a fixed plate 1, on which a mounting countersunk hole 5 is provided, and the mounting countersunk hole 5 is pre-installed on the vehicle by bolts, and the fixed plate 1 is provided with an inclined platform 6.

The eccentric buckle 207 is arranged on the knob 208, which rotates with the knob shaft 204. The handle 209 is clamped on the knob 208. When the knob 208 is driven to rotate clockwise or counterclockwise around the knob shaft 204 by twisting the handle 209, the eccentric buckle 207 performs planetary motion around the knob shaft 204 in the rotating groove 205. The up and down movement direction in the planetary trajectory of the eccentric buckle 207 drives the hook 201 to move up and down in the slide groove 206 through the transverse groove 202. At the same time, the left and right movement directions in the planetary trajectory of the eccentric buckle 207 move in the same direction in the transverse groove 202 and are limited by the transverse groove 202. After installing the fixing plate, align the rear end of the vehicle-mounted communication device 4 with the rear end of the fixing plate 1, and place the front end of the vehicle-mounted communication device 4 on the inclined entry platform 6. At this time, the vehicle-mounted communication device 4 is in a tilted state, and is pushed forward.
