Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of bulldozer cabs, and in particular relates to a bulldozer seat mounting structure. Background Art
[0002] Currently, bulldozer seats are equipped with a suspension system that can be adjusted as needed, but the armrests, control handles, and safety locks are all fixed to the floor frame. This structure provides good driver seat comfort, but as the seat floats, the distance between the seat and the control handles and armrests also constantly adjusts and floats. This cannot meet the needs of drivers of different heights, body shapes, and driving habits, especially for smaller operators. In terms of stability, it is inconvenient to maintain the driver's stability and balance, especially when going up and down hills and turning. In terms of safety, the large distance between the seat and the safety lock makes it difficult for the operator to brake in time. The safety lock is located on the right side of the seat, making it easy to forget to lock it when exiting the vehicle, which may lead to a certain risk of loss of control. Utility Model Content
[0003] In order to solve the technical problem in the background technology that the seat suspension causes the distance between the seat and the operating handle, armrest, etc. to change, causing inconvenience to the operator, the purpose of the utility model is to provide a bulldozer seat mounting structure that can solve the above problem.
[0004] The technical solution to achieve the purpose of the utility model is: a bulldozer seat mounting structure, including a seat body, an operating handle, an armrest, an armrest box and a safety lock, the operating handle, armrest and safety lock are installed on the armrest box, and the armrest box is fixed on the seat body.
[0005] In this solution, the control handle and other structures are centrally fixed on the seat body, thereby solving the technical problem of inconvenience to the operator after the seat body is suspended. Specifically, the control handle, armrest and safety lock are all installed on the armrest box, and the armrest box is fixed on one side of the seat body. In this way, when the suspension device at the bottom of the seat body drives the seat to float up and down, the control handle, armrest and safety lock all float with the seat. In other words, the positions of the control handle, armrest and safety lock and other devices and the operator remain unchanged. After the driver adjusts the seat to a suitable position, he can always maintain a relatively comfortable position to drive the bulldozer for a long time. The armrest box can not only provide installation space for components such as the control handle and safety lock, but can also be used to provide storage space, etc. The control handle includes mechanical handles and hydraulic handles commonly used in bulldozers.
[0006] Furthermore, the armrest box has a mounting plate at its bottom with mounting holes on it, and a fixing plate corresponding to the mounting plate is provided on the seat body. The armrest box is fixed to the seat body via bolts, the mounting plate, and the fixing plate. The bolted fixing method of the armrest box facilitates installation and removal, and facilitates subsequent disassembly and maintenance.
[0007] Furthermore, the armrest box includes a left armrest box and a right armrest box. The left armrest box is located near the cockpit door. The safety lock is installed on the left armrest box, and the operating rod of the safety lock protrudes toward the front of the seat body. In traditional bulldozer cab structures, the safety lock is usually installed on the right side of the seat body, and the driver enters and exits the cockpit from the left side of the seat body. In this structure, the safety lock is installed on the left side of the seat body, and the operating rod of the safety lock protrudes toward the front of the seat. In other words, when the driver wants to exit the cockpit, his legs are restricted by the operating rod of the safety lock, and he must first pull up the operating rod of the safety lock before he can exit smoothly. This arrangement is safer and can immediately brake the bulldozer when the driver leaves the seat body to prevent the bulldozer from rolling away and other related problems. The operating rod of the safety lock can also be set to a telescopic style, which can be extended and retracted to prevent the problem of the driver's legs being too large in the cockpit and not being able to restrain the driver from exiting the cockpit.
[0008] Furthermore, the armrest is curved, with its protruding portion facing the seat body. The bent portion of the armrest is securely fastened to the outer corner of the armrest box. The driver's elbow can be comfortably placed on the protruding portion, providing support. The armrest can also be made of sponge to increase flexibility and enhance driver comfort. It can also be made of PVC for easier molding and a certain degree of support.
[0009] By adopting the above technical solution, the utility model has the following beneficial effects:
[0010] (1) The armrests, operating handles, and safety locks are integrally fixed to the seat body. Even if the seat body floats up and down under the action of the suspension device, it will not affect the operator's operation;
[0011] (2) The armrest box is fixed to the seat body by bolts, which is convenient for installation and disassembly, and subsequent maintenance;
[0012] (3) The safety lock is located on the left side of the seat body, that is, near the cockpit door. When the driver exits, he must first pull up the safety lock, otherwise it will restrain the driver's legs, preventing the driver from forgetting to pull up the safety lock when exiting the cockpit.
[0013] (4) The armrest is bent, which is convenient for installation at the corner of the armrest box, does not take up a large installation space, and the raised part effectively supports the driver's elbow, thereby improving the driver's comfort. BRIEF DESCRIPTION OF THE DRAWINGS

[0017] The numbers in the accompanying drawings are: 1 seat body; 2 operating handle; 3 armrest; 4 safety lock; 5 mounting plate; 6 mounting hole; 7 left armrest box; 8 right armrest box; 9 operating lever; 10 protrusion; 11 bend of armrest; 12 suspension device. DETAILED DESCRIPTION
[0018] Example:
[0019] like Figure 1 and Figure 2 As shown, this embodiment provides a bulldozer seat mounting structure, comprising a seat body 1, a joystick 2, an armrest 3, an armrest box, and a safety lock 4. The joystick 2, armrest 3, and safety lock 4 are mounted on the armrest box, which is fixed to the seat body 1. In this solution, the joystick 2 and other components are centrally fixed to the seat body 1, thereby resolving the technical problem of inconvenience caused to the operator when the seat body 1 is suspended. Specifically, the joystick 2, armrest 3, and safety lock 4 are all mounted on the armrest box, which is fixed to one side of the seat body 1. This allows the joystick 2, armrest 3, and safety lock 4 to float along with the seat when the suspension device 12 at the bottom of the seat body 1 causes the seat to float up and down. This means that the joystick 2, armrest 3, and safety lock 4 remain in the same position as the operator. Once the operator has adjusted the seat to the appropriate position, they can maintain a relatively comfortable position while operating the bulldozer for extended periods. The armrest box not only provides space for mounting components such as the joystick 2 and safety lock 4, but also provides storage space. The operating handle includes a mechanical handle and a hydraulic handle commonly used in bulldozers.
[0020] Preferably, the bottom of the armrest box has a mounting plate 5 with mounting holes 6, and the seat body 1 has a fixing plate corresponding to the mounting plate 5. The armrest box is fixed to the seat body 1 by bolts, the mounting plate 5, and the fixing plate. The bolted fixing method of the armrest box facilitates installation and removal, and is conducive to subsequent disassembly and maintenance.
[0021] Preferably, the armrest box includes a left armrest box 7 and a right armrest box 8. The left armrest box 7 is located near the cockpit door. The safety lock 4 is mounted on the left armrest box 7, and the operating lever 9 of the safety lock 4 protrudes forward of the seat body 1. In conventional bulldozer cab structures, the safety lock 4 is typically mounted on the right side of the seat body 1, and the driver enters and exits the cab from the left side of the seat body 1. In this structure, the safety lock 4 is mounted on the left side of the seat body 1, and the operating lever 9 of the safety lock 4 protrudes forward of the seat body. In other words, when the driver wants to exit the cab, their legs are constrained by the operating lever 9 of the safety lock 4, and they must first pull up the operating lever 9 of the safety lock 4 before they can exit smoothly. This arrangement is safer and allows the bulldozer to be braked immediately upon leaving the seat body 1, preventing the bulldozer from rolling away and other related problems. The operating lever 9 of the safety lock 4 can also be configured as a telescopic design, which can be extended to prevent the driver's legs from being too wide in the cab and not being restrained from exiting the cab.
[0022] Preferably, the armrest 3 is bent, with its protrusion 10 facing toward the seat body 1. The armrest's bend 11 is securely fastened to the outer corner of the armrest box. The driver's elbow can be conveniently placed on the protrusion, providing support. The armrest 3 can also be made of sponge for increased flexibility and driver comfort. It can also be made of PVC for easier molding and a certain degree of support.
[0023] Working principle: First, install the structural components such as the operating handle 2, armrest 3 and safety lock 4 on the armrest box, and then fix the armrest box to the seat body 1 with bolts, so that the seat body 1 will not affect the driver's operation of the operating handle and other components under the action of the suspension device 12; the safety lock 4 is located on the left side of the seat body 1, and the safety lock 4 must be pulled up when leaving the cockpit, otherwise the operating rod 9 of the safety lock 4 will restrain and block the driver's legs, reminding the driver that he must pull up the operating rod 9 of the safety lock 4 before leaving the cockpit.
[0024] The specific embodiments described above further illustrate the purpose, technical solutions and beneficial effects of the present invention in detail. It should be understood that the above description is only a specific embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
