Description

Technical Field

[0001] This utility model relates to the field of agricultural machinery operation technology, specifically to a multifunctional handrail box with extended functions. Background Technology

[0002] Agricultural machinery operators often face scenarios involving long hours of fieldwork. The cab space is compact, and breaks between tasks are short, requiring operators to conveniently complete basic needs such as meals within the cab. Existing agricultural machinery handrail boxes mostly only retain basic storage functions and lack a dedicated structure designed for the core need of drivers to eat within the cab during work breaks. Drivers must place temporary storage boards outside the cab when eating, which not only takes up already limited driving space but also poses a safety hazard as the food tray may slip due to bumps in the vehicle.

[0003] In addition, some height-adjustable handrail boxes for agricultural machinery use a simple manual adjustment structure, which has low adjustment accuracy and is cumbersome to operate, making it difficult to adapt to the elbow support needs of drivers of different heights; even if some handrail boxes are equipped with trays, they lack a stable support mechanism, and the trays are prone to shaking when carrying plates, bowls and chopsticks, which cannot meet the stability requirements of dining scenarios.

[0031] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be described in detail below. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0032] See Figures 1-5 As shown, this utility model provides a multifunctional armrest box with extended functions, including: armrest box body 1, lifting component 2, tray 3 and support mechanism 4.

[0033] The lifting assembly 2 is fixedly connected to the bottom of the armrest box body 1 and is used to lift the armrest box body 1; the support plate 3 is installed on the top of the armrest box body 1; the support mechanism 4 is fixedly installed on the lifting assembly 2 and is used to support the support plate 3. The lifting assembly 2 can be engaged with the support mechanism 4 by extending and can be disengaged from the support mechanism 4 by retracting.

[0034] As an optional implementation, the tray 3 has a concave surface 5 on the side corresponding to the driver. The edge of the tray 3 is provided with a retaining wall 7. A hollow groove is formed on the tray 3, and the hollow groove is in clearance fit with the storage box cover 6 of the armrest box body 1.

[0035] See Figure 4 and Figure 5The lifting assembly 2 includes an outer shell 201, an inner shell 202 slidably connected inside the outer shell 201, and the top of the inner shell 202 fixedly connected to the armrest box body 1. An electric push rod 204 is vertically fixedly connected inside the inner shell 202, and the movable end of the electric push rod 204 is fixedly connected to the inner shell 202. A telescopic rod 203 is vertically fixedly connected inside the outer shell 201, and both ends of the telescopic rod 203 are fixedly connected to the outer shell 201 and the inner shell 202, respectively. A vertically formed groove 205 corresponding to the surface of the inner shell 202 is formed on the outer shell 201.

[0036] In this embodiment, the inner housing 202 is moved vertically by the electric push rod 204. The inner housing 202 and the outer housing 201 have a mutual guiding effect, making the movement of the inner housing 202 more stable. The telescopic rod 203 can further improve the stability of the inner housing 202 during movement.

[0037] See Figure 1 , Figure 3 as well as Figure 4 The support mechanism 4 includes a first hook 403 fixedly connected to the outer shell 201 and a second hook 405 fixedly connected to the inner shell 202, with the second hook 405 passing through the strip groove 205. The support mechanism 4 also includes a diagonal brace 401 and a diagonal tie rod 402 fixedly connected to the diagonal brace 401. The diagonal brace 401 and the diagonal tie rod 402 form a Y-shape. A first through hole 404 and a second through hole 406 are respectively provided on the diagonal brace 401 and the diagonal tie rod 402, which are respectively engaged with the first hook 403 and the second hook 405. The upper side of the diagonal brace 401 is rotatably connected to the support plate 3. This arrangement connects the support mechanism 4 to the support plate 3, preventing parts from becoming scattered and lost.

[0038] In this embodiment, the support mechanism 4 serves as the main support component for the pallet 3. First, the first hook 403 is connected to the first through hole 404, and the second through hole 406 is connected to the second hook 405. The second hook 405 moves upward with the inner shell 202 and is connected to the second through hole 406. At that time, the support mechanism 4 can be fixedly installed on the lifting assembly 2.

[0039] With the above structure, the lifting component 2 serves as the core component for height adjustment of the armrest box body 1, adaptable to agricultural machinery drivers of different heights. Its operation is driven by the electric push rod 204. The support mechanism 4 is specifically designed for the tray 3 to support dining items such as plates, bowls, and chopsticks. Through its interlocking with the lifting component 2, it provides stable support for the tray 3, preventing the dining items from slipping due to agricultural machinery vibrations.

[0040] The diagonal brace 401 and the diagonal tie rod 402 of the support mechanism 4 form a Y-shaped structure, which has a strong anti-bump load capacity. The upper side of the diagonal brace 401 is rotatably connected to the pallet 3, which can prevent the pallet 3 from being lost during the bumps of the agricultural machinery after disassembly. In the initial state, the first through hole 404 on the diagonal brace 401 is first hooked to the first hook 403 on the outer shell 201 to complete the initial fixation of the support mechanism 4. The second hook 405 on the inner shell 202 moves upward synchronously with the inner shell 202 until it is precisely hooked to the second through hole 406 on the diagonal tie rod 402. At this time, the support mechanism 4 forms a stable triangular support structure for the pallet 3 through the double fixation of the first hook 403 and the second hook 405.

[0041] When there is no need for meals, the electric push rod 204 drives the inner housing 202 to descend, and the second hook 405 descends synchronously with the inner housing 202 and disengages from the second through hole 406, so that the tray 3 can be retracted, saving driving space.

[0042] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
