[0043] See also Figure 1 , Figure 2 and Figure 3 The utility model discloses a multifunctional vehicle-mounted device rack, which is mainly used for placing vehicle machines or vehicle-mounted devices that are not installed on the vehicle, for example, in the process of testing vehicle machines or vehicle-mounted devices. The multifunctional vehicle-mounted device rack includes a plurality of vehicle machine placement racks 1 arranged in sequence up and down. The number of the vehicle machine placement racks can be two or more. The vehicle machine placement racks are in a right-angle bending shape (L-shaped in longitudinal section / side projection), including a bottom plate 2 and a back plate with perpendicular plate surfaces. The bottom plate is used to place vehicle machines or vehicle-mounted devices. In any two vehicle machine placement racks adjacent to each other up and down, a matching detachable plug-in fixing mechanism is provided between the bottom plate of the vehicle machine placement rack located above and the back plate of the vehicle machine placement rack located below, and the bottom plates are connected by the plug-in fixing mechanism. A spacing is left between the bottom plates of any two vehicle machine placement racks adjacent to each other up and down (there is space for placing vehicle machines or vehicle-mounted devices). Since the plurality of vehicle machine placement racks are arranged in layers up and down, the overall space occupied by the multifunctional vehicle-mounted device rack is small, and multiple vehicle machines or vehicle-mounted devices can be placed in layers at the same time, which is both beautiful and practical. The adjacent vehicle machine placement racks are detachably connected via the plug-in fixing mechanism, and an appropriate number of vehicle machine placement racks can be selected for assembly according to actual usage needs (the number of vehicle machines or vehicle-mounted devices that need to be placed), and the usage methods are flexible and diverse. In addition, when there is no need to place a vehicle machine or vehicle-mounted device, the plug-in fixing mechanisms can be disassembled, and several vehicle machine placement racks can be stacked up and down to reduce the vertical space occupied and facilitate movement or storage.

[0044] The heights of the vehicle machine racks can be the same or different.

The number of the pin holes on the back plate is multiple, and the multiple pin holes are preferably distributed in two rows along the vertical direction and the horizontal heights correspond one to one. The two rows of pin holes are respectively arranged on the left and right sides of the board surface of the back plate and correspond to the vertical positions of the button latches on the bottom plate. With such an arrangement, the spacing between the bottom plates of adjacent vehicle machine placement racks can be flexibly adjusted when assembling the multifunctional vehicle-mounted device rack to accommodate vehicle machines or vehicle-mounted devices of different heights.

[0049] The pin hole is preferably a through hole that passes through the surface of the back plate, and a metal column sleeve (such as a cylindrical sleeve, equivalent to the pin nose) that matches the pin column of the button latch can be embedded in the through hole to prevent the pin hole from being worn out due to long-term and repeated disassembly and assembly of the vehicle machine placement rack, resulting in instability after assembly.

[0050] The plug-in fixing mechanism may also adopt any other connection mechanism suitable for detachable fixed connection between two plates with perpendicular plate surfaces in the prior art, such as a three-in-one connector or matching bolts and nuts.

[0051] The left and right ends of the rear edge of the bottom plate are preferably provided with vertical plates 5 extending vertically upward, with a spacing between the two vertical plates (referring to the spacing in the left and right directions), the two vertical plates constitute the back plate, and the two rows of pin holes are respectively provided on the two vertical plates. This arrangement not only saves material but also helps to ventilate the vehicle machine or vehicle-mounted device placed on the bottom plate.

[0052] The top ends of the two vertical plates are preferably fixedly connected with a horizontal plate 6, that is, the left and right ends of the horizontal plate are respectively fixedly connected with the top ends of the vertical plates on the corresponding sides, so as to improve the structural strength and stability of the back plate.

[0053] The bottom plate is preferably provided with a through hole that passes through the plate surface from top to bottom, or the rear end surface of the bottom plate is provided with an inward groove 7. The through hole or the groove can be located in the middle of the rear side of the bottom plate.
