Description

Technical Field

[0001] This utility model belongs to the technical field of driver's cab table, and in particular relates to a foldable and expandable driver's cab small table device. Background Technology

[0002] With the continuous development of modern transportation, especially commercial vehicles, long-distance buses, and high-end RVs, the human-centered and comfortable design of the driver's cab is receiving increasing attention. During long drives, drivers often need to take short breaks, eat, record driving information, use electronic devices, or handle simple office tasks inside the vehicle, thus increasing the functional requirements for auxiliary facilities within the cab. However, traditional driver's cabs have limited interior space and a compact layout, typically lacking a dedicated control panel or storage platform. This results in a lack of stable and safe support for the driver during breaks in driving or when the vehicle is parked, making it extremely inconvenient to use.

[0003] Currently, although there are some in-vehicle tray table products on the market, most of them are fixed or simply foldable, which have many limitations: First, fixed tray tables occupy space for a long time, affecting the passage and layout flexibility of the driving operation area; second, ordinary foldable tray tables are mostly flip-up or pull-down designs, with limited adjustment range, making it difficult to meet the needs of drivers of different sizes or diverse usage scenarios; third, the desktop area of ​​existing products is fixed and cannot be expanded according to actual needs, limiting their functionality.

[0004] To address these issues, we have developed a foldable and extendable cab table system. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0024] Example

[0025] Please see Figure 1-3 The present invention is a foldable and expandable cab small table device, including a telescopic and adjustable storage table 200 and a base 100 for mounting and supporting the storage table 200. The base 100 includes a base 102, ear seats 103 fixed to the middle of both sides of the base 102, and a guide rod 104 passing through the ear seats 103.

[0026] The storage table 200 includes a bracket 201 sleeved and installed outside the guide rod 104, a scissor-type telescopic frame 202 disposed between the brackets 201, a segmented table 204 fixed to the top of the brackets 201, and an extension plate 203 telescopically disposed in the middle of the segmented table 204.

[0027] Specifically, a lower positioning frame 206 is fixed at the middle position of the upper side of the base 102, and an upper positioning frame 208 is provided above the lower positioning frame 206. A screw 207 is provided between the lower positioning frame 206 and the upper positioning frame 208. The bottom of the screw 207 passes through the base 102 and is connected to the rotation drive inside it. The lower positioning frame 206 and the upper positioning frame 208 are located inside the scissor telescopic frame 202 to form a left and right telescopic drive system, and the lower positioning frame 206 and the upper positioning frame 208 are located directly below the extension plate 203.

[0028] Furthermore, baffles 105 are fixed at both ends of the guide rod 104. The baffles 105 are arranged parallel to the lower end of the bracket 201. The bracket 201 is perpendicular to the guide rod 104. An intercepting strip 205 is provided at the upper edge of the segmented table 204, and the segmented table 204 is symmetrically arranged about the center line of the extension plate 203. An mounting plate 101 is fixed at the bottom of the base 102. A positioning hole for fastener installation is opened at the corner of the mounting plate 101. The mounting plate 101 is fixed to the interior of the driver's cab by fasteners.

[0029] The structural principle of the foldable extendable cab table device provided in this embodiment is to achieve multi-dimensional adjustment and stable support of the table in a limited space, taking into account both convenient storage and functionality. The overall structure uses the base 100 as the basic mounting unit. The device is firmly fixed to a suitable position in the cab using fasteners via the mounting plate 101, ensuring the stability and safety of the overall structure. A base 102 is provided in the middle of the base 100, and ear seats 103 are mounted on the middle of both sides. A guide rod 104 passes through the ear seats 103 to form a lateral guide structure, providing guidance and support for the lateral extension and retraction of the table 200. Baffles 105 are provided at both ends of the guide rod 104 to limit the travel range of the bracket 201 during extension and retraction, preventing it from detaching and ensuring smooth and reliable operation. The table 200 is sleeved on the guide rod 104 via the bracket 201, achieving a sliding connection with the base 100. A scissor-type telescopic frame 202 is connected between the brackets 201. This scissor-type telescopic frame 202, together with the internally installed screw 207 drive system, forms a left-right extension and retraction drive mechanism.

[0030] Specifically, a lower positioning frame 206 is installed in the middle of the upper surface of the base 102, and an upper positioning frame 208 is installed above it. The two are connected by a screw 207, the bottom of which passes through the base 102 and is connected to a rotary drive device. When the rotary drive drives the screw 207 to rotate, the upper positioning frame 208 is pushed up and down relative to the lower positioning frame 206 through threaded transmission, thereby driving the scissor-type telescopic frame 202 to unfold or retract, thus driving the entire tabletop 200 to achieve lateral telescopic movement. This drive system is integrated inside the scissor-type telescopic frame 202, with a compact structure and space-saving design. The tabletop body adopts a segmented tabletop 204 symmetrically arranged on both sides of the extension plate 203, with a telescopic extension plate 203 in the middle. It can be pulled out to expand the desktop area according to usage needs, improving practicality. An intercepting strip 205 is set on the upper edge of the segmented tabletop 204 to prevent items from slipping and improve safety. The entire device, through the composite structure of guide rod 104 and scissor telescopic frame 202, realizes multiple adjustment functions of horizontal telescopic extension of the table and expansion of the tabletop area, fully adapting to the narrow and variable operating space requirements in the cab, and achieving the goal of "folding and storing without taking up space, unfolding and using with stability and practicality".

[0031] The specific steps of using this utility model are as follows: First, in the initial storage state, the entire storage table 200 is in a folded and retracted position, with the segmented table 204 and extension plate 203 both folded up above the base 102. The scissor-type telescopic frame 202 is in a folded state, with the lateral dimension minimized, which saves space when the cab is not in use. When the small table is needed, the driver or passenger first drives the screw 207 to rotate by controlling the drive device. Since the bottom of the screw 207 is connected to the rotation drive in the base 102, its rotation drives the upper positioning frame 208 to rise along the screw 207, while the lower positioning frame 206 remains fixed. The relative movement between the two pushes the scissor-type telescopic frame 202 to unfold. At the same time as the scissor-type telescopic frame 202 unfolds, the bracket 201 slides along the guide rod 104 to ensure the horizontal stability and straightness of the lifting process and prevent swaying or deviation. Once the tabletop is raised to the appropriate height, the user can manually pull the middle extension plate 203 horizontally out from the gap in the segmented tabletop 204 to expand the usable desktop area and meet the needs of placing larger items. The intercepting strips 205 set on the edge of the segmented tabletop 204 can effectively prevent items such as cups, mobile phones, or documents from accidentally slipping off. After use, the operation process is reversed: first, push the extension plate 203 back to its original position, then rotate the drive screw 207 in the opposite direction to reverse, causing the upper positioning frame 208 to descend, and the scissor-type telescopic frame 202 to retract accordingly. The entire tabletop 200 descends and gradually retracts to its initial position above the base 102, ultimately achieving complete folding and storage. The entire operation is simple and smooth. The lateral position adjustment is achieved through mechanical linkage, ensuring both flexibility and comfort in use, as well as efficient utilization of the cab space.
