Description

Technical Field

[0001] The invention relates to the technical field of vehicle-mounted shock absorption, and in particular to a shock absorber used for a vehicle-mounted instrument shock absorption platform. Background Art

[0002] VOC detector is a special precision instrument used to detect VOC (volatile organic compounds). The weight of the equipment is about 300kg and the height is about 1.5m. During the transportation of VOC detector, it is inevitable that the vehicle will brake, turn, bump, etc. At this time, the detector will have large inertia and vibration, which is easy to cause damage and directly affect the detection accuracy of the detector.

[0003] Shock absorbers are devices that accelerate the attenuation of vibrations of the vehicle frame, body, and onboard objects to improve the smoothness and comfort of the vehicle. Most existing shock absorbers are designed for automobile body shock absorption, and have complex structures and cannot be directly used for shock absorption of onboard instruments. Therefore, how to properly configure shock absorbing devices, improve the stability of onboard precision instruments, and buffer the vibrations caused by vehicle driving have become urgent issues to be solved in the transportation of precision instruments.

[0004] For this purpose, a shock-absorbing fixing frame has appeared in the prior art. For example, Chinese patent document CN207889643U discloses a special vehicle-mounted instrument shock-absorbing fixing frame, which involves shock-absorbing equipment and facilities, including a wall, a fixing block is provided on the wall and the two are connected by screws, the fixing block is connected to a support block A and the two are fixed by an angle block, the support block A is connected to a support block B, a shockproof device is connected to the support block B, the shockproof device is connected to a fixing seat, an instrument body is fixed inside the fixing seat, the support block A is connected to one end of the shock absorber and the two are fixed by screws, and the other end of the shock absorber is in contact with the wall. This shock-absorbing fixing frame is large in size, occupies a lot of space in the vehicle, needs to be complexly installed with the vehicle body when used, and the method of clamping and fixing the instrument equipment by the fixing seat is not reliable, and the accident of the instrument equipment falling off is prone to occur, and the reliability is poor. In addition, the shock absorber used in this shock-absorbing bracket is a spring shock absorber. Although the spring can absorb part of the vibration when the vehicle body bumps and vibrates, the reciprocating motion of the spring itself does not help much in restoring the stability of the instrument. Therefore, the shock-absorbing effect of this shock absorber on the vehicle-mounted instrument is relatively poor, and the smooth transportation of the vehicle-mounted instrument cannot be guaranteed.

[0037] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0038] like Figure 1 As shown, it is a preferred embodiment of a vehicle-mounted instrument shock-absorbing platform involved in the present invention, and the vehicle-mounted instrument shock-absorbing platform is used to fix, shock-absorb and buffer the vehicle-mounted instruments and equipment when the vehicle brakes, turns, bumps, etc.

[0039] The vehicle-mounted instrument shock-absorbing platform includes a platform base 1 that can be fixedly connected to the bottom surface of the vehicle body, and a plurality of vertical shock-absorbing devices and a plurality of horizontal shock-absorbing devices arranged on the platform base 1. The upper parts of the vertical shock-absorbing devices and the horizontal shock-absorbing devices are both connected to the platform top plate 2. The vehicle-mounted instrument is placed on the platform top plate 2. The vertical shock-absorbing devices only limit the vertical movement of the platform top plate 2, and the horizontal shock-absorbing devices only limit the horizontal movement of the platform top plate 2.

[0040] In this embodiment, the platform base 1 is rectangular, preferably a long rectangle, and the platform top plate 2 is a rectangle matching the platform base 1. Two mutually symmetrical rectangular through holes are formed on the platform top plate 2 and the platform base 1 to facilitate the inspection and maintenance of internal components. In the vehicle-mounted instrument shock-absorbing platform of the present invention, the platform top plate 2 is the main load-bearing component, so in order to increase its load-bearing strength, the lower surface of the platform top plate 2 has a reinforcing rib 14, such as Figure 2 shown.

[0041] In order to better place the on-board instruments and equipment, the upper surface of the platform top plate 2 is provided with a connection component that matches the bottom surface shape of the on-board instrument. The on-board instrument shock-absorbing platform in this embodiment is designed for VOC detectors or GCMS (gas chromatograph-mass spectrometer), so the structure of the connection component matches the bottom surface shape of the VOC detector. Specifically, the connection component includes four skirt plates 11 arranged perpendicular to the platform top plate 2, and the adjacent skirt plates 11 are connected by side feet 9. A middle foot 10 is also provided in the middle position of a group of relatively arranged skirt plates 11. A notch 15 is formed on the skirt plate 11, and the notch 15 is suitable for matching and connecting with the bottom surface of the VOC detector. The skirt plate 11, the side foot 9, and the middle foot 10 together constitute a protruding frame-like structure, and match the bottom surface shape of the VOC detector, so that the VOC detector can be quickly placed on the shock-absorbing platform.

[0042] like Figure 3 As shown, in order to more evenly buffer and limit the vibration and shaking that may occur during the transportation of the instrument, the vertical shock absorbing device and the horizontal shock absorbing device are preferably arranged in such a way that at least one horizontal shock absorbing device is provided between adjacent vertical shock absorbing devices. Specifically, since the platform top plate 2 in this embodiment is rectangular, the vertical shock absorbing device and the horizontal shock absorbing device are provided along the four sides of the platform base 1. One vertical shock absorbing device is provided at each of the four corners of the platform base 1, and one vertical shock absorbing device is provided at the middle position of each pair of long sides of the platform base 1, two horizontal shock absorbing devices are provided between the adjacent vertical shock absorbing devices on the long sides of the platform base 1, and three horizontal shock absorbing devices are provided between the adjacent vertical shock absorbing devices on the short sides of the platform base 1.

[0043] The vertical shock absorbing device adopts a damper 13, and the horizontal shock absorbing device adopts a shock absorber 3. After the damper 13 is connected to the platform top plate 2, it only limits the vertical movement of the platform top plate 2 (i.e., up and down vibration), and does not limit the horizontal movement of the platform top plate 2 (i.e., front and back, left and right shaking). Correspondingly, after the shock absorber 3 is connected to the platform top plate 2, it only limits the horizontal movement of the platform top plate 2 (i.e., front and back, left and right shaking), and does not limit the vertical movement of the platform top plate 2 (i.e., up and down vibration).

[0044] like Figure 4 and 5 The figure shows a preferred embodiment of the shock absorber for the vehicle-mounted instrument shock absorbing platform of the present invention.

[0045] The shock absorber 3 includes a shock absorbing upper frame 301, a shock absorbing lower frame 302, and a shock absorbing connecting rod 303 connecting the shock absorbing upper frame 301 and the shock absorbing lower frame 302. The shock absorbing lower frame 302 is fixed to the bottom surface of the vehicle compartment, the shock absorbing upper frame 301 is integrally linked with the vehicle-mounted instrument, the two ends of the shock absorbing connecting rod 303 are rotatably connected to the shock absorbing upper frame 301 and the shock absorbing lower frame 302 in a vertical plane, and the end of the shock absorbing connecting rod 303 connected to the shock absorbing upper frame 301 is provided with a shock absorbing component for shock absorbing the horizontal shaking of the shock absorbing upper frame 301.

[0046] In this embodiment, the shock-absorbing upper frame 301 is integrally linked with the vehicle-mounted instrument through the platform top plate 2 of the shock-absorbing platform. Figure 6As shown, the shock-absorbing upper frame 301 has an upper frame fixing plate 304 connected to the platform top plate 2 and two upper frame connecting plates 305 perpendicular to the platform base 1 and extending toward the platform base 1. The two upper frame connecting plates 305 are parallel to each other, and corresponding positions of the two upper frame connecting plates 305 are formed with upper frame through holes 306. The upper frame fixing plate 304 is fixedly connected to the platform top plate 2 by screws.

[0047] In this embodiment, the shock-absorbing lower frame 302 is fixed to the bottom surface of the vehicle compartment through the platform base 1 of the shock-absorbing platform. Figure 7 As shown, the shock-absorbing lower frame 302 has a lower frame fixing plate 307 connected to the platform base 1 and two lower frame connecting plates 308 perpendicular to the platform base 1 and extending toward the platform top plate 2. The two lower frame connecting plates 308 are parallel to each other, and lower frame through holes 309 are formed at corresponding positions of the two lower frame connecting plates 308. The lower frame fixing plate 307 is fixedly connected to the platform base 1 by screws.

[0048] like Figure 8 As shown, the two ends of the shock absorbing connecting rod 303 are respectively an upper frame connecting portion 310 and a lower frame connecting portion 311. The lower frame connecting portion 311 is formed with a lower frame assembly hole 312, and the lower frame assembly hole 312 is connected with the two lower frame through holes 309 through a lower frame connecting screw 313, so that the shock absorbing connecting rod 303 can rotate around the lower frame connecting screw 313.

[0049] The upper frame connection portion 310 is formed with an upper frame assembly hole 314, and the shock absorbing component is arranged in the upper frame assembly hole 314. The shock absorbing component is a hanging rubber 315, and the hanging rubber 315 is axially limited in the upper frame assembly hole 314 (that is, the hanging rubber 315 cannot move in its axial direction). In this embodiment, the hanging rubber 315 is limited in the upper frame assembly hole 314 in the following manner: a step is formed on one side end face (positioning end) of the upper frame assembly hole 314, and the hanging rubber 315 is inserted into the upper frame assembly hole 314 from the other side end face (installation end) and abuts against the step and cannot extend out; thereafter, a pressing sheet 316 is installed at the installation end by screws to press the hanging rubber 315, so that the hanging rubber 315 is limited in the upper frame assembly hole 314.

[0050] like Fig. 9As shown, the suspension rubber 315 includes a suspension rubber outer ring 317, a suspension rubber inner ring 318 and a buffer portion 319, wherein the buffer portion 319 is filled between the suspension rubber outer ring 317 and the suspension rubber inner ring 318, wherein the suspension rubber inner ring 318 is integrally linked with the shock-absorbing upper frame 301 in a horizontal plane, and the suspension rubber outer ring 317 is integrally fixed with the shock-absorbing connecting rod 303 and the shock-absorbing lower frame 302 in a horizontal plane. The central portion of the suspension rubber inner ring 318 has a suspension rubber assembly hole 320.

[0051] The outer rubber hanging ring 317 and the inner rubber hanging ring 318 are made of metal, such as iron, aluminum, etc. The buffer part 319 is made of elastic material. In this embodiment, the material of the buffer part 319 is rubber.

[0052] The hanging rubber assembly hole 320 is connected to the two upper frame through holes 306 via an upper frame connecting screw 321 , and the hanging rubber 315 together with the shock absorbing connecting rod 303 can rotate around the upper frame connecting screw 321 .

[0053] The shock absorption principle of the shock absorber 3 is as follows: the inner ring of the hanging rubber is integrally linked with the shock-absorbing upper frame, the platform top plate and the instruments and equipment in the horizontal plane, and the outer ring of the hanging rubber is integrally fixed with the shock-absorbing connecting rod, the shock-absorbing lower frame and the bottom surface of the car in the horizontal plane; when the vehicle shakes, the inner ring of the hanging rubber, the shock-absorbing upper frame, the platform top plate and the instruments and equipment shake together, while the outer ring of the hanging rubber, the shock-absorbing connecting rod, the shock-absorbing lower frame and the bottom surface of the car are relatively still. At this time, the buffer part of the hanging rubber absorbs the shaking, thereby making the instruments and equipment tend to be stable.

[0054] In order to prevent debris or human hands from getting stuck in the shock-absorbing platform, the shock-absorbing platform also includes a protective frame, which is fixedly connected to the platform top plate 2, and the bottom of the protective frame is suspended. The protective frame includes a protective frame 8 and a front protective plate 4, a rear protective plate 5, a left protective plate 6, and a right protective plate 7 installed on the protective frame 8. The upper parts of the front protective plate 4, the rear protective plate 5, the left protective plate 6, and the right protective plate 7 have a bending portion 12 fixedly connected to the plane of the platform top plate 2. The front protective plate 4 is adjacent to and connected to the left protective plate 6 and the right protective plate 7, and the rear protective plate 5 is adjacent to and connected to the left protective plate 6 and the right protective plate 7, thereby forming the protective frame. The bottom of the protective frame is suspended, which means that the bottom surfaces of the front protective plate 4, the rear protective plate 5, the left protective plate 6, and the right protective plate 7 are suspended and do not contact the bottom surface of the car body.

[0055] The shock absorbing process of the vehicle-mounted instrument shock absorbing platform of the present invention on the instrument equipment is described in detail as follows:

[0056] When instruments and equipment need to be transported, the instruments and equipment to be transported are placed on the upper surface of the platform top plate, and the bottom surface of the instruments and equipment is assembled with the connecting components; when the vehicle is driving, when bumps occur, the instruments and equipment shake up and down together with the platform top plate, and the damper can buffer the up and down shaking to make the instruments and equipment tend to be stable; when the vehicle turns or shakes, the instruments and equipment shake horizontally together with the platform top plate, and the shock absorber can buffer the horizontal shaking to make the instruments and equipment tend to be stable.

[0057] In other embodiments, the number and arrangement of the vertical shock absorbing devices and the horizontal shock absorbing devices can be modified and designed according to usage requirements.

[0058] Obviously, the above embodiments are merely examples for the purpose of clear explanation, and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived therefrom are still within the scope of protection of the invention.
