Description

Technical Field

[0001] The invention relates to the field of equipment integration, and in particular to a vehicle-mounted multifunctional telescopic workbench. Background Art

[0002] With the rapid development of vehicle-mounted integration technology, shelter vehicles are widely used in various industries and in more and more usage scenarios. In some usage scenarios, traditional non-expandable shelters cannot meet the usage requirements due to the limitations of the vehicle chassis and usage area, and expanded shelters must be used.

[0003] The expansion cabin has a driving and transportation state before expansion and an expanded use state after expansion. Due to the limitations of road and rail transportation, the width of the cabin vehicle in the driving and transportation state must be within 2500mm. The internal integrated layout of the cabin in the expanded use state is restricted by multiple factors such as the cabin area, the number of people working in the cabin, and the equipment composition. In the usual design, the workbench and equipment in the expansion cabin are arranged in the non-expansion area in the middle, which can meet the needs of a certain number of people and are not affected by the expansion. However, it also causes problems such as low utilization rate of the expansion area as an office area, low office comfort, small number of people working, and electronic equipment cannot be moved. In order to optimize the integrated layout design in the cabin, improve the utilization rate of the cabin area, meet the needs of more staff, and the requirements that electronic equipment can be moved with the workbench, a vehicle-mounted multifunctional telescopic workbench that can change its length in the expansion cabin according to the expansion of the cabin is designed.

[0004] The vehicle-mounted multifunctional telescopic workbench is based on the basic principles of relative movement and self-locking of the work surface. Combined with the design concept of the vehicle-mounted workbench, it adopts reinforced design in terms of raw material selection, structural form, connection method, etc., so that the product can meet the requirements of vibration, impact and other uses in harsher vehicle environments. Summary of the invention

[0005] The purpose of the present invention is to provide a vehicle-mounted multifunctional telescopic workbench to solve the problems existing in the prior art.

[0006] The technical solution adopted to achieve the purpose of the present invention is as follows: a vehicle-mounted multifunctional telescopic workbench includes an electric side-pull telescopic mechanism, a frame, a first desktop, a second desktop, a third desktop and a folding bracket.
