[0046] The following will describe in detail some embodiments of the present invention with reference to the drawings. Without conflict, the following embodiments and the features in the embodiments can be combined with each other.

[0047] As Figure 1 、 Figure 2 and Figure 3 shown, a shock-absorbing device for a vehicle-mounted data collector provided by the present invention includes: a connection assembly 1, a collector body 2, a buffer assembly 3, a shock-absorbing housing 4, a buffer sponge 5, and a clamping assembly 6;

[0048] The top end of the connection assembly 1 is detachably connected to the collector body 2, the bottom end of the connection assembly 1 is connected to the shock-absorbing housing 4 through the buffer assembly 3, the shock-absorbing housing 4 is filled with the buffer sponge 5 inside, and several uniformly distributed clamping assemblies 6 are fixedly connected to the bottom end of the shock-absorbing housing 4;

[0049] As Figure 8As shown in the figure, the buffer assembly 3 includes a fixed seat 301, a raised block 302, a slide bar 303, a movable plate 304, a first spring 305, and an absorber 306. The fixed seat 301 is in a C shape, and the open end of the fixed seat 301 is fixedly connected to the shock-absorbing housing 4. At both sides of the other end surface of the open end of the fixed seat 301, raised blocks 302 extend upward. Between the two raised blocks 302, two slide bars 303 are arranged in parallel. A movable plate 304 is sleeved between the two slide bars 303. At both ends of the movable plate 304, first springs 305 are sleeved on the surface of the slide bars 303. At the central position of the movable plate 304, an absorber 306 is provided, and the absorber 306 is fixedly connected to the connection assembly 1.

[0050] Specifically, the top end of the connection assembly 1 and the collector body 2 are fixedly connected in a detachable connection manner. When the collector body 2 needs to be taken or placed, it avoids the traditional technology of opening the housing of the collector body 2 and tightening bolts from top to bottom, increasing the installation time cost.

[0051] One or more buffer assemblies 3 are bonded or welded to the bottom end of the connection assembly 1. The buffer assemblies 3 are fixed on the top surface of the shock-absorbing housing 4. The shock-absorbing housing 4 is filled with buffer sponge 5 inside. When the vehicle shakes, the vibration will be transmitted to the shock-absorbing housing 4 first. The shock-absorbing housing 4 shakes. At this time, because the buffer sponge 5 that can buffer is filled inside, due to its porous structure, the buffer sponge 5 has good elastic deformation characteristics, can absorb external forces, and disperse the forces, reducing the shaking amplitude of the shock-absorbing housing 4, serving as the first-stage shock absorption.

[0052] The buffer assembly 3 includes a fixed seat 301 in a C shape. The fixed seat 301 fixes the open end downward to the top end of the shock-absorbing housing 4. At both sides of the other end surface of the fixed seat 301, raised blocks 302 extend upward, providing a support position for the first spring 305.

[0053] It should be noted that the fixed seat 301 can also be in an H shape or other shapes that can fix to the shock-absorbing housing 4 at the bottom end and provide support for the first spring 305 at the top end.

[0054] Between the two raised blocks 302, two slide bars 303 are arranged in parallel. At the central position between the two slide bars 303, a movable plate 304 that can slide left and right is sleeved. On each slide bar 303, first springs 305 with the same length at both ends are sleeved. The first springs 305 at both ends are located on both sides of the movable plate. When the vehicle shakes, although the buffer sponge 5 in the shock-absorbing housing 4 absorbs the first-stage shaking, the shock-absorbing housing 4 will still generate horizontal shaking. At this time, the shock-absorbing housing 4 will also shake accordingly, and the first springs 305 on both sides will absorb a part of the left and right shaking forces, serving as the second-stage shock absorption.

[0055] An absorber 306 is provided at the top of the center of the movable plate 304, and the top of the absorber 306 is fixedly connected to the connecting assembly 1. The absorber 306 is vertically set at the bottom of the movable plate 304 and the connecting assembly 1, and the connecting assembly 1 is connected to the collector body 2. During the shaking process, when there is up and down bumps, the absorber 306 will absorb the vertical shaking, which serves as the third level of shock absorption.

[0056] As an embodiment of a connection component 1 in the present invention, Figure 4 , Figure 5 , Figure 6 As shown, the connection assembly 1 includes a housing 101, a worm 102, a torsion bar 103, a worm gear 104, a first spur gear 105, a slide groove 106, a T-shaped slider 107, a second spur gear 108 and a screw 109;

[0057] The bottom end of the shell 101 is fixedly connected to the absorber 306, and a worm 102 is inserted into the shell 101. The end of the worm 102 facing away from the shell 101 is fixedly connected to a torque 103. The worm 102 is meshed with a turbine 104 arranged inside the shell 101, and the turbine 104 is meshed with the first straight tooth 105. Two parallel slide grooves 106 are opened on both sides of the first straight tooth 105 through the inside of the shell 101. A T-shaped slider 107 is slidably connected in the slide groove 106. The top of the T-shaped slider 107 is rack-shaped. Both T-shaped sliders 107 are meshed with the first straight tooth 105. Each T-shaped slider 107 is also meshed with a plurality of second straight teeth 108 on the side facing away from the first straight tooth 105. A screw 109 is provided on the top surface of the second straight tooth 108. The screw 109 passes through the top of the shell 101 and is threadedly connected to the collector body 2.

[0058] Specifically, the cross-section of the shell 101 is rectangular, and the bottom end of the shell 101 is fixedly connected to the absorber 306. A worm 102 is inserted into one side of the shell 101. The worm 102 can be screwed in or out relative to the shell 101, and a twist knob 103 is installed. Since parts are provided at both ends of the shell 101, it is difficult to disassemble. Therefore, by controlling the worm 102 and the twist knob 103 to rotate from the side, the screw 109 can be screwed upward into the thread at the bottom end of the collector body 2, thereby connecting the shell 101 to the collector body 2. Screwing in from the side is more convenient than tightening the bolts from top to bottom.

[0059] The threaded part of the worm 102 extending into the interior of the housing 101 meshes with the turbine 104 fixed inside the housing 101 through a fixed shaft. Further, the turbine 104 is driven to rotate. At this time, the rotational force generated by driving the turbine 104 drives the first straight gear 105 to rotate; on both sides of the first straight gear 105, two sliding grooves 106 are arranged in parallel inside the housing 101. A T-shaped slider 107 is slidably connected in each sliding groove 106. The bottom end of the T-shaped slider 107 is inserted into the interior of the sliding groove 106, and the two side edges of the top end are in the shape of a rack or fixedly connected with a long strip-shaped rack for meshing with both sides of the first straight gear 105. When the first straight gear 105 rotates, it drives the T-shaped slider 107 to slide in the sliding groove 106.

[0060] At one end of the top surface of the T-shaped slider 107 away from the first straight gear 105, two rotatable second straight gears 108 are meshed. The second straight gears 108 are arranged through a fixed shaft, thereby gradually screwing out the screw rod 109 from the housing 101, exposing the surface of the housing 101. Further, the connecting component 1 and the collector body 2 are detachably connected through the screw rod 109, which can not only ensure the stable connection of the two when in the connected state, but also ensure convenient disassembly by screwing in from the side when disassembling.

[0061] As another embodiment of the connecting component 1 in the present invention, as Figure 3 shown, magnets are laid on the surface of the connecting component 1 and / or the bottom surface of the collector body 2.

[0062] Specifically, a layer of magnets is directly laid on the surface of the housing 101 or the bottom surface of the collector body 2, or both, so that the two can be detachably connected. This embodiment is more rapid in disassembly and does not require multiple internal gears for transmission, saving costs.

[0063] In the embodiment of the present invention, if the number of the buffer components 3 is one, the buffer component 3 is located at the central position of the collector body 2; if the number of the buffer components 3 is multiple, the buffer components 3 are symmetrically arranged.

[0064] Specifically, when the number of the buffer components 3 is single, costs are saved. However, considering the force-bearing problem and the shock absorption effect, the size of the buffer component 3 needs to be increased and it is set at the central position for shock absorption; preferably, when the number of the buffer components 3 is two or four, they are symmetrically arranged in pairs. As Figure 7 shown, there are two buffer components 3, arranged diagonally, which can reduce vibration to the greatest extent and maintain stability.

[0065] As an embodiment of an absorber 306 in the present invention, as Figure 8 shown, the absorber 306 includes a connecting rod 307, a spring chamber 308, a second spring 309 and a fixed rod 310;

[0066] The bottom end of the connecting rod 307 is fixedly connected to the central position of the movable plate 304. A spring cavity 308 is provided at the top end of the connecting rod 307. A second spring 309 is provided at the central position inside the spring cavity 308. The top end of the spring cavity 308 is fixedly connected to the connecting component 1 through a fixing rod 310.

[0067] Specifically, the bottom end of the connecting rod 307 is fixedly connected to the central position of the movable plate 304. A second spring 309 is installed between the center of the spring cavity 308 and the center of the connecting rod 307. The spring cavity 308 is circular and is connected to the bottom surface of the connecting component 1 through the fixing rod 310 at the top end. A part of the shaking force can be absorbed through the second spring 309.

[0068] As another implementation manner of the absorber 306 in the present invention (not shown in the drawings), the absorber 306 is a damping spring. One end of the damping spring is fixed at the central position of the movable plate 304, and the other end of the damping spring is fixed at the bottom surface of the connecting component 1. While ensuring the cost, a part of the shaking force can also be absorbed to damp the collector body 2 at the top end of the connecting component 1.

[0069] In the embodiment of the present invention, as Figure 9 、 Figure 10 、 Figure 11 shown, the clamping component 6 includes a circular shell 601, a first lead screw 602, a knob 603, a first helical gear 604, a transmission component 605, a second helical gear 606, a second lead screw 607, a claw 608, and a sliding rod 609;

[0070] The top end of the circular shell 601 is fixedly connected to the bottom end of the shock-absorbing outer shell 4. The first lead screws 602 are evenly distributed on the outer peripheral surface of the circular shell 601. A knob 603 is fixedly connected to the end of the first lead screw 602 away from the circular shell 601. A first helical gear 604 is fixedly connected to the end of the first lead screw 602 penetrating into the circular shell 601. The first helical gear 604 is meshed and connected to the transmission component 605. The end of the transmission component 605 away from the first helical gear 604 is meshed with the second helical gear 606. One end of the second lead screw 607 passes through the circular shell 601. The second helical gear 606 is fixedly sleeved outside the second lead screw 607 and forms a threaded connection with the second lead screw 607. The other end of the second lead screw 607 abuts against the central position of the claw 608; the claw 608 is fixed through the sliding rod 609 passing through the circular shell 601.

[0071] Specifically, as Figure 9 、 Figure 10 、 Figure 11As shown, the round shell 601 is in a circular shape with openings on both sides, and the top of the round shell 601 is fixedly connected to the bottom of the shock-absorbing housing 4, providing a structure for the shock-absorbing housing 4 to be connected to the vehicle. Four first screw rods 602 are evenly distributed on the outer circumferential surface of the round shell 601, and each first screw rod 602 can be screwed into or out of the round shell 601. The end of the first screw rod 602 away from the round shell 601 is fixedly connected to a knob 603, which is used for easy operation. The knob 603 can be directly clamped on the protruding column of the vehicle through the claw 608, and then the knob 603 is manually rotated in sequence to rotate the first screw rod 602 into the housing, so that the claw 608 moves inward and clamps on the protruding outer surface to prevent loosening during the driving of the vehicle. One end of the first screw rod 602 that penetrates into the round shell 601 is fixedly connected with the first beveled tooth 604, and the first beveled tooth 604 transmits power through the transmission assembly 605. The radial force of manually rotating the first screw rod 602 causes the first beveled tooth 604 to rotate, thereby driving the second beveled tooth 606 inside the round shell 601 to rotate; wherein, the second beveled tooth 606 is sleeved with the second screw rod 607 through a threaded sleeve and forms a threaded connection, so that when the second beveled tooth 606 rotates, the second screw rod 607 can achieve linear displacement. The other end of the second screw rod 607 is abutted against the center position of the claw 608, and the second screw rod 607 moves to push the claw 608 to lock inward, thereby fixing it. wherein, the claw 608 is penetrated by a sliding rod 609 through the top opening to achieve the supporting effect when being pushed by the second screw rod 607.

[0072] In an embodiment of the present invention, the transmission assembly 605 includes a first bevel gear 610, a connecting shaft 611 and a second bevel gear 612;

[0073] The first bevel gear 610 and the second bevel gear 612 are fixedly connected to both sides of the connecting shaft 611 . The first bevel gear 610 is meshed with the first oblique gear 604 , and the second bevel gear 612 is meshed with the second oblique gear 606 .

[0076] In the embodiment of the present invention, the buffer sponge 5 is a foam sponge, so as to reduce the shaking of the shock-absorbing shell 4.

[0077] Based on the above embodiments, the working process of the shock absorbing device of the vehicle-mounted data collector provided by the present invention is as follows:

[0078] First, operate the first screw 602 through the knob 603 in the clamping assembly 6 to clamp the claw 608 on the protruding block of the vehicle to achieve rapid installation of the shock absorbing device; place the collector body 2 on the top of the connecting assembly 1, rotate the knob 103 and the worm 102, so that the four screws 109 are screwed upward into the bottom of the connecting assembly 1 to complete the installation.

[0079] When the vehicle shakes, the vibration is first transmitted to the shock-absorbing shell 4, and the internal buffer sponge 5 absorbs and disperses the force, reducing the shaking amplitude of the shock-absorbing shell, which serves as the first level of shock absorption. The movable plate 304 and the first spring 305 on the fixed seat 301 constitute a buffer assembly, which absorbs the shaking in the horizontal direction, which serves as the second level of shock absorption. The absorber 306 is vertically set up between the movable plate 304 and the connecting assembly 1, which absorbs the shaking in the vertical direction, which serves as the third level of shock absorption.
