Description

Technical Field

[0001] This utility model relates to the field of loader technology, and in particular to a shock-absorbing and sealing structure, a cab, and a loader. Background Technology

[0002] A skid steer loader, also known as a skid steer loader, multi-purpose engineering vehicle, or multi-purpose engineering machine, is a wheeled specialized chassis equipment that uses the difference in linear speed between the wheels on both sides to achieve vehicle steering. It is mainly used in situations where the work area is confined, the ground is uneven, and the work content changes frequently.

[0003] To facilitate the inspection and maintenance of components beneath the cab, skid steer loaders typically employ a split-type tilting cab. This type of cab consists of a floor compartment and the cab body. The front end of the cab body is connected to the frame via shock absorbers, while the rear end is fixed to the upper frame via rubber bushings. The floor compartment and control lever mechanism are connected to the frame by welding and bolting, allowing the windshield, side panels, rear window, roof, and bottom seat to tilt backward as a single unit. The floor compartment and control lever mechanism are fixed to the bottom frame and cannot be tilted. This rigid connection between the floor compartment and the frame makes it difficult for the cab to effectively isolate vibrations and impacts from the road surface during operation, resulting in poor shock absorption. This not only affects the stability of the cab but also reduces driving comfort, poses safety hazards to the driver, and generates significant noise, negatively impacting the driver's experience.

[0004] Therefore, a shock-absorbing and sealing structure, a cab, and a loader are needed to solve the above problems. Utility Model Content

[0040] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

[0044] like Figures 1 to 11As shown, this embodiment provides a shock-absorbing and sealing structure, which is connected between the vehicle frame 100 and the floor compartment 200. The floor compartment 200 includes a foot plate 201, a vertical plate 202, and a mounting plate 203 connected in sequence. The shock-absorbing and sealing structure includes a first shock-absorbing component, a second shock-absorbing component, and a noise reduction component. The first shock-absorbing component is connected between the foot plate 201 and the vehicle frame 100, the second shock-absorbing component is connected between the mounting plate 203 and the vehicle frame 100, and the noise reduction component is sealed between the foot plate 201 and the vehicle frame 100. The noise reduction component includes a first noise reduction element 31 and a second noise reduction element 32. The first noise reduction element 31 is disposed at the flange 2011 of the foot plate 201, and the second noise reduction element 32 is fitted to the vehicle frame 100, with the first noise reduction element 31 and the second noise reduction element 32 abutting against each other. Specifically, in this embodiment, the floor compartment 200 includes a footboard 201, a vertical plate 202, and a mounting plate 203 connected in sequence, thus making the floor compartment 200 an integral structure and improving its overall integrity. The first shock-absorbing component of the shock-absorbing and sealing structure is connected between the frame 100 and the footboard 201, and the second shock-absorbing component is connected between the frame 100 and the mounting plate 203, thus ensuring that the floor compartment 200 is vibration-isolated from the frame 100, effectively reducing noise in the cab and improving the driver's driving experience. The first noise-reducing component 31 of the noise-reducing component is disposed at the flange 2011 of the footboard 201, and the second noise-reducing component 32 is disposed on the frame 100, with the first noise-reducing component 31 and the second noise-reducing component 32 abutting against each other, thus providing two layers of noise reduction between the floor compartment 200 and the frame 100, improving the vibration isolation effect between the floor compartment 200 and the frame 100, and further reducing noise in the cab.

[0045] Specifically, in this embodiment, the foot plate 201, the upright plate 202 and the mounting plate 203 are arranged in a "Z" shape, and the foot plate 201, the upright plate 202 and the mounting plate 203 are integrated, thereby improving the overall integrity of the floor compartment 200.

[0046] Furthermore, such as Figures 5 to 8 As shown, the first noise reduction component 31 includes a connecting portion 311 and a noise reduction portion 312 connected together. The connecting portion 311 is detachably connected to the flange 2011 of the foot plate 201, and the noise reduction portion 312 is disposed at one end of the connecting portion 311 away from the flange 2011 of the foot plate 201. Specifically, in this embodiment, the connecting portion 311 is detachably connected to the flange 2011 of the foot plate 201, which facilitates the installation and replacement of the first noise reduction component 31, improving the convenience of installation and replacement of the first noise reduction component 31. The noise reduction portion 312 is disposed at one end of the connecting portion 311 away from the flange of the foot plate 201, which allows the noise reduction portion 312 to be located between the flange of the foot plate 201 and the frame 100, improving the sound insulation performance of the noise reduction portion 312, and at the same time avoiding collisions between the foot plate 201 and the frame 100, further reducing noise generation.

[0047] Furthermore, such as Figure 6 As shown, the connecting part 311 is provided with a plug groove 3111, which is plugged into the flange 2011 of the foot plate 201. Specifically, in this embodiment, the connecting part 311 includes a support member and a rubber sleeve wrapped around the support member. The support member has a "U" shaped structure, which allows the support member and the rubber sleeve wrapped around the support member to form the plug groove 3111. The plug groove 3111 can be plugged into the flange 2011 of the foot plate 201. The rubber sleeve can ensure that the connecting part 311 and the foot plate 201 have a good connection effect, thereby ensuring stability during use. At the same time, the second noise reduction member 32 and the first noise reduction member 31 abut against each other, which can also prevent the connecting part 311 of the first sealing member from detaching from the flange 2011 of the foot plate 201, thereby improving the connection stability between the first noise reduction member 31 and the foot plate 201.

[0048] Furthermore, such as Figure 8 As shown, the first sidewall of the insertion groove 3111 is provided with a plurality of spaced-apart first lips 3112, and the second sidewall of the insertion groove 3111 is provided with a plurality of spaced-apart second lips 3113, with the plurality of first lips 3112 and the plurality of second lips 3113 being arranged alternately. Specifically, in this embodiment, this arrangement can increase the friction between the inner wall of the insertion groove 3111 and the flange 2011 of the foot plate 201, further preventing the first noise reduction component 31 from detaching from the flange 2011 of the foot plate 201, thereby ensuring both the noise reduction effect and the connection stability between the first noise reduction component 31 and the flange 2011 of the foot plate 201, ensuring the stability of the cab during use.

[0049] Furthermore, such as Figure 6 and Figure 8 As shown, the noise reduction part 312 has a noise reduction cavity 3121. Specifically, in this embodiment, the noise reduction part 312 is fixedly connected to the rubber sleeve outside the support member. The noise reduction part 312 has a uniform wall thickness, thereby forming a noise reduction cavity 3121 in the middle of the noise reduction part 312. This arrangement allows the noise reduction cavity 3121 of the noise reduction part 312 to deform when the frame 100 and the floor compartment 200 move relative to each other, thereby making the first noise reduction part 312 and the second noise reduction part 312 in flexible contact. This can reduce the wear of the first noise reduction part 312 and the second noise reduction part 312, extend the service life of the first noise reduction part 312 and the second noise reduction part 312, and at the same time ensure the relative movement of the frame 100 and the floor compartment 200, thereby avoiding mutual collision and generating greater noise, and thus reducing the noise in the cab.

[0050] Specifically, in this embodiment, the second noise reduction component 32 and the first noise reduction component 31, except for the support component, are all made of rubber, which can improve the noise reduction effect between the frame 100 and the floor compartment 200, reduce the noise in the driver's cab, and improve the driver's driving experience.

[0051] Optionally, in this embodiment, the second noise reduction part 312 and the first noise reduction part 312, except for the support member, are both made of EPDM rubber by injection molding, and the Shore hardness of the EPDM rubber is preferably 60±5HA, without specific limitations.

[0052] Specifically, in this embodiment, the second noise reduction part 312 is a noise reduction sponge, and the second noise reduction part 312 is glued to the frame 100, thereby ensuring its installation stability and performance.

[0053] Optionally, in this embodiment, the material of the second noise reduction part 312 is EVA sponge, and its hardness can be selected according to actual use, without specific limitations.

[0054] Furthermore, such as Figure 9 As shown, the first shock absorption assembly includes a plurality of first shock absorbers 11, which are evenly distributed; the second shock absorption assembly includes a plurality of second shock absorbers 21, which are spaced apart. Specifically, in this embodiment, four first shock absorbers 11 are provided, and the four first shock absorbers 11 are respectively provided at the four corners of the foot plate 201, thereby improving the connection stability between the frame 100 and the foot plate 201, optimizing the force balance of the foot plate 201, and thus improving the performance of the foot plate 201; two second shock absorbers 21 are provided, which are spaced apart. This arrangement can improve the connection stability between the frame 100 and the mounting plate 203. Due to the force balance of the mounting plate 203, the reliability of the mounting plate 203's installation position is improved.

[0055] Furthermore, such as Figure 11 As shown, the first shock absorber 11 includes a first damping pad and a first fastening assembly. The first damping pad passes through the frame 100 and abuts against the foot plate 201. The first fastening assembly passes through the damping pad and the foot plate 201 to connect the first damping pad between the frame 100 and the foot plate 201. And / or, the second shock absorber 21 includes a second damping pad and a second fastening assembly. The second damping pad passes through the frame 100 and abuts against the mounting plate 203. The second fastening assembly passes through the damping pad and the mounting plate 203 to connect the first damping pad to the frame 100 and the mounting plate 203.

[0056] Specifically, in this embodiment, as Figure 11As shown, the first shock-absorbing pad includes a first stepped pad and a first ring pad 121. A first through hole is provided on the frame 100. The first stepped pad includes a first cylinder 111, a second cylinder 112, and a third cylinder 113. The second cylinder 112 of the first stepped pad passes through the first through hole. The first cylinder 111 of the first stepped pad abuts against the end face of the frame 100 away from the footplate 201. The first ring pad 121 is fitted around the outer periphery of the third cylinder 113 of the first rubber pad. The footplate 201 is provided with a second through hole. A fastening assembly includes a first screw 114, a first nut 115, and two first washers 116. The first screw 114 passes through the center hole and the second through hole of the first stepped pad in sequence and is threadedly connected to the first nut 115. One of the first washers 116 is sandwiched between the screw head of the first screw 114 and the first cylinder 111, and the other first washer 116 is sandwiched between the foot plate 201 and the first nut 115, thereby connecting the first shock absorber 11 between the frame 100 and the foot plate 201.

[0057] Specifically, in this embodiment, the second shock absorber includes a second stepped pad and a second ring pad. A third through hole is provided on the frame 100. The second stepped pad includes a fourth cylinder, a fifth cylinder, and a sixth cylinder. The fifth cylinder of the second stepped pad passes through the third through hole. The fourth cylinder of the second stepped pad abuts against the end face of the frame 100 away from the mounting plate 203. The second ring pad is sleeved on the outer periphery of the sixth cylinder of the second rubber pad. The mounting plate 203 is provided with a fourth through hole. The second fastening assembly includes a second screw, a second nut, and two second washers. The second screw passes through the center hole and the fourth through hole of the second stepped pad in sequence and is threadedly connected to the second nut. One of the second washers is sandwiched between the screw head of the second screw and the fourth cylinder, and the other second washer is sandwiched between the mounting plate 203 and the second nut, thereby connecting the second shock absorber 21 between the frame 100 and the mounting plate 203.

[0058] like Figures 1 to 4 As shown, this embodiment also provides a driver's cab, which includes a floor compartment 200 and the aforementioned shock-absorbing and sealing structure. A first shock-absorbing component is connected between the foot plate 201 of the floor compartment 200 and the frame 100, and a second shock-absorbing component is connected between the mounting plate 203 of the floor compartment 200 and the frame 100. A noise reduction component is sealed between the foot plate 201 and the frame 100. This driver's cab, by incorporating the aforementioned shock-absorbing and sealing structure, can reduce noise during driving through shock absorption, and further improve the sound insulation effect of the cab through the two sealing features of the shock-absorbing and sealing structure, thereby enhancing the driving experience.

[0059] Furthermore, such as Figures 1 to 3As shown, the cab also includes a joystick mechanism 300, which is mounted on the mounting plate 203. Specifically, in this embodiment, the joystick mechanism 300 is mounted on the mounting plate 203 by fasteners, thereby connecting the joystick mechanism 300 and the floor compartment 200 into a whole. This allows for effective vibration isolation between the joystick mechanism 300 and the frame 100, reducing the amount of vibration of the joystick mechanism 300, improving operating comfort, and enhancing the driving experience.

[0060] This embodiment also provides a loader, which includes the aforementioned cab. By providing the aforementioned cab, cab vibration can be reduced, and noise during operation can be effectively reduced, thus improving the comfort of the loader.
