For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0029] Some embodiments of the present invention are described in detail below in conjunction with the accompanying drawings. In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other.

[0030] like Figure 1 , Figure 2 and Figure 3 As shown, a shock absorbing device for a vehicle-mounted data collector provided by the present invention comprises: a connecting component 1, a collector body 2, a buffer component 3, a shock absorbing shell 4, a buffer sponge 5 and a clamping component 6; The top of the connecting component 1 is detachably connected to the collector body 2, and the bottom of the connecting component 1 is connected to the shock-absorbing shell 4 through the buffer component 3. The inside of the shock-absorbing shell 4 is filled with a buffer sponge 5, and the bottom of the shock-absorbing shell 4 is fixed with a plurality of evenly distributed clamping components 6; like Figure 8As shown, the buffer assembly 3 includes a fixed seat 301, a protruding block 302, a sliding rod 303, a movable plate 304, a first spring 305 and an absorber 306; the fixed seat 301 is C-shaped, the open end of the fixed seat 301 is fixedly connected to the shock-absorbing shell 4, and the two side edges of the surface of the other end of the opening of the fixed seat 301 extend upward to form a protruding block 302, two sliding rods 303 are arranged in parallel between the two protruding blocks 302, a movable plate 304 is sleeved between the two sliding rods 303, first springs 305 are sleeved on the two ends of the movable plate 304 through the surface of the sliding rod 303, an absorber 306 is arranged at the center of the movable plate 304, and the absorber 306 is fixedly connected to the connecting assembly 1.

[0031] Specifically, the top of the connecting assembly 1 is fixedly connected to the collector body 2 in a detachable manner. When the collector body 2 needs to be taken in and out, the traditional technique of opening the collector body 2 shell and tightening the bolts from top to bottom is avoided, which increases the installation time cost. One or more buffer components 3 are bonded or welded to the bottom of the connection component 1, and the buffer component 3 is fixed to the top surface of the shock-absorbing shell 4, and the shock-absorbing shell 4 is filled with a buffer sponge 5. When the vehicle shakes, the vibration will be transmitted to the shock-absorbing shell 4 first, and the shock-absorbing shell 4 shakes. At this time, because the interior is filled with buffer sponges 5, the buffer sponges 5 have good elastic deformation characteristics due to their porous structure, and can absorb external forces and disperse the forces, thereby reducing the shaking amplitude of the shock-absorbing shell 4, which serves as the first level of shock absorption.

[0032] The buffer assembly 3 includes a C-shaped fixing seat 301, which fixes the fixing seat 301 with one open end facing downward to the top of the shock-absorbing housing 4, and the two side edges of the other end surface of the fixing seat 301 extend upward to form a protrusion 302 to provide a support position for the first spring 305.

[0033] It should be noted that the fixing seat 301 may also be in an H shape or other shape that can be fixed to the shock absorbing housing 4 at the bottom end while providing support for the first spring 305 at the top end.

[0034] Two sliding bars 303 are arranged in parallel between the two raised blocks 302, and a movable plate 304 that can slide left and right is sleeved at the center position between the two sliding bars 303, and each sliding bar 303 is sleeved with a first spring 305 of the same length at both ends, and 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 shell 4 absorbs the first-level shaking, the shock-absorbing shell 4 will still produce horizontal shaking. At this time, the shock-absorbing shell 4 will also follow the shaking, and the first springs 305 on both sides will absorb part of the left and right shaking force as the second-level shock absorption.

[0035] 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.

[0036] 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; 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.

[0037] 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.

[0038] The threaded portion of the worm 102 extending into the housing 101 is meshed with a turbine 104 fixed to the housing 101 through a fixed shaft, thereby driving the turbine 104 to rotate. At this time, the rotational force generated by the driving turbine 104 will drive the first straight tooth 105 to rotate; two parallel slide grooves 106 are arranged on both sides of the first straight tooth 105 in the housing 101, and each slide groove 106 is slidably connected with a T-shaped slider 107, and the bottom end of the T-shaped slider 107 is inserted into the interior of the slide groove 106, and the edges on both sides of the top end are rack-shaped or fixed with a long strip of rack, which is used to mesh with the two sides of the first straight tooth 105. When the first straight tooth 105 rotates, it drives the T-shaped slider 107 to slide in the slide groove 106.

[0039] The top surface of the T-shaped slider 107 is meshed with two rotatable second spur teeth 108 at one end away from the first spur teeth 105. The second spur teeth 108 are arranged by a fixed axis, so that the screw 109 is gradually screwed out of the shell 101 to expose the surface of the shell 101, and then the connecting component 1 and the collector body 2 are detachably connected through the screw 109, which can ensure that the connection between the two is stable when in the connected state, and can also ensure that they can be screwed in from the side when disassembled, which is convenient for disassembly.

[0040] As another embodiment of the connection assembly 1 in the present invention, Figure 3 As shown, magnets are laid on the surface of the connecting component 1 and / or the bottom surface of the collector body 2 .

[0041] Specifically, a layer of magnets is directly laid on the surface of the shell 101 or the bottom surface of the collector body 2, or both, so that the two can be detachably connected. This embodiment is faster to disassemble and does not require multiple internal gears for transmission, saving costs.

[0042] In the embodiment of the present invention, if there is one buffer component 3 , the buffer component 3 is located at the center of the collector body 2 ; if there are multiple buffer components 3 , the buffer components 3 are symmetrically arranged.

[0043] Specifically, when the number of buffer components 3 is single, the cost is saved, but considering the force problem and the shock absorption effect, the size of the buffer component 3 needs to be increased and it needs to be set at the exact center for shock absorption; preferably, when the number of buffer components 3 is two or four, they are symmetrically arranged in pairs, such as Figure 7 As shown, there are two buffer components 3, which are arranged diagonally, so as to reduce vibration to the greatest extent and maintain stability.

[0044] As an embodiment of an absorbent 306 in the present invention, Figure 8 As shown, the absorber 306 includes a connecting rod 307, a spring chamber 308, a second spring 309 and a fixing rod 310; The bottom end of the connecting rod 307 is fixedly connected to the center of the movable plate 304 , the top of the connecting rod 307 is provided with a spring cavity 308 , a second spring 309 is provided at the center of the spring cavity 308 , and the top of the spring cavity 308 is fixedly connected to the connecting assembly 1 via a fixing rod 310 .

[0045] Specifically, the bottom end of the connecting rod 307 is fixedly connected to the center of the movable plate 304, and 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. Part of the shaking force can be absorbed by the second spring 309.

[0046] As another embodiment of the absorber 306 in the present invention (not shown in the drawings), the absorber 306 is a damping spring, which can be any one of a compression spring, a rubber spring, a composite spring or an air bag spring. One end of the damping spring is fixed to the center of the movable plate 304, and the other end of the damping spring is fixed to the bottom surface of the connecting component 1. While ensuring the cost, it can also absorb part of the shaking force and reduce the shock of the collector body 2 at the top of the connecting component 1.

[0047] In an embodiment of the present invention, Fig. 9 , Fig.10 , Fig.11 As shown, the clamping assembly 6 includes a round shell 601, a first screw rod 602, a knob 603, a first bevel gear 604, a transmission assembly 605, a second bevel gear 606, a second screw rod 607, a claw 608 and a sliding rod 609; The top of the circular shell 601 is fixedly connected to the bottom end of the shock-absorbing shell 4, and the first screw rod 602 is evenly distributed on the outer surface of the circular shell 601. The end of the first screw rod 602 facing away from the circular shell 601 is fixedly connected to the knob 603, and the end of the first screw rod 602 that penetrates into the circular shell 601 is fixedly connected to the first bevel gear 604, the first bevel gear 604 is meshed with the transmission component 605, and the end of the transmission component 605 facing away from the first bevel gear 604 is meshed with the second bevel gear 606, one end of the second screw rod 607 passes through the circular shell 601, the second bevel gear 606 is fixedly sleeved outside the second screw rod 607 and forms a threaded connection with the second screw rod 607, and the other end of the second screw rod 607 abuts against the center position of the claw 608; the claw 608 is fixed by a sliding rod 609 that passes through the circular shell 601.

[0048] Specifically, Fig. 9 , Fig.10 , Fig.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.

[0049] 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; 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 .

[0050] A fixing block 613 is fixedly connected to the inner surface of the circular shell 601 , and the second screw rod 607 and the sliding rod 609 both pass through the fixing block 613 . A circular ring 614 also passes through the top of the fixing block 613 . The circular ring 614 is located at the connecting shaft 611 and has a hanging ring 615 extending downwardly.

[0052] In the embodiment of the present invention, the buffer sponge 5 includes any one of polyurethane sponge, EVA sponge or foam sponge. The buffer sponge 5 can reduce the shaking of the shock-absorbing shell 4.

[0053] 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: 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.

[0054] 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.
