Also, in the present embodiment, the flexible mat 5 may still be provided between the connecting bracket 21 and the housing of the trunk. The provided flexible mat 5 has a good anti-seismic effect. In particular, for the present embodiment, this flexible mat 5 may be provided at a portion where the suspension cross member 21c contacts the rear seat.

Fifth embodiment

The fifth embodiment of the present invention provides a vehicle-mounted projection apparatus and an electronic device mounting apparatus, wherein the fifth embodiment is different from the vehicle-mounted projection apparatus and the electronic device mounting apparatus provided by the third and fourth embodiments, and the main difference lies in that, in the fifth embodiment of the present invention, a connection manner different from relying on a headrest fixing column or a hanging beam 21c is provided.

Specifically, in the present embodiment, as shown in fig. 5 and 6a, the connecting bracket 21 is fixedly connected to the protective plate 4 through a prepared hole 41 in the protective plate 4 at the bottom of the housing of the rear compartment.

As a result of research, the inventors have realized that in various models of automobiles of the related art, a protective plate 4 for protecting parts under a trunk is often provided, and for example, in the case of an electric or hybrid automobile type, a protective plate 4 for protecting a battery is provided. A prefabricated hole 41 penetrating the protective plate 4 is often provided in the protective plate 4 of the vehicle body. These prefabricated holes 41 are already provided at the time of shipment, but are not substantially used after shipment.

The present embodiment realizes stable and reliable fixed connection by means of the original prefabricated hole 41 on the protection plate 4 of the vehicle body. Therefore, the present embodiment also has better reliability without damaging the original structure of the vehicle body.

Of course, when the protection plate 4 of the vehicle body itself does not have the prepared hole 41, the prepared hole 41 may be processed for use.

Specifically, in the present embodiment, the connecting bracket 21 includes: and the connecting cross beam 21d is fixedly connected with the protection plate 4 through at least two prefabricated holes 41 arranged on the protection plate 4 at the bottom of the shell of the rear compartment.

Of course, the stud prefabricated on the connecting beam 21d is also connected to the fixing nut 21g through the prefabricated hole 41. In addition, it is also feasible to directly connect the preformed hole 41 with the clamping column formed on the protective plate 4. There are many specific connection methods, and therefore, they will not be described in detail herein.

The stability can be significantly increased by the connection of the two prefabricated holes 41 to the provided connecting cross beam 21 d. When only one prefabricated hole 41 is provided, the auxiliary connection can be performed in a clamping, abutting and other modes. Moreover, when the electronic device 1 includes the projection mechanism, the projection light emitted by the projection mechanism can be exactly positioned within the interval range of the preferred projection angle by the design of the shape and the structure of the fixing bracket 22 after being fixed through the preformed hole 41, and a good and stable projection effect can be obtained. And a flexible sleeve can be arranged at the position of the connecting beam 21d passing through the prefabricated hole 41 to play a role of shock absorption.

Referring to fig. 5 and 6a, when the protection plate 4 is provided with 4 or more prefabricated holes 41, the number of the connection beams 21d may be correspondingly increased, and the connection stability may be remarkably improved by a plurality of connection beams 21d connected to each other. Of course, when only one prefabricated hole 41 is provided, the technical object of the present invention can be achieved even though the fixing stability is not as good as that of the case of two or more prefabricated holes 41.

In the prior art, there are situations where it is difficult, if not impossible, to open the protective panel 4 of a part of the car. At this time, the fixing clip plate 21h can be easily inserted into the slit below the protection plate 4. After the fixing screw holes of the fixing clip plate 21h are aligned with the preformed holes 41 and the through holes 21d3, the fixing can be completed by the fixing bolts 21 f. Therefore, by fixing the fixing clip plate 21h and the bolt, the mounting can be made easier than the fixing of the nut and the bolt.

It is worth mentioning that in order to better place the fixing catch plate 21h under the protection plate 4, i.e. in the slot at the side of the protection plate 4 facing away from the space in the trunk, the shape of the fixing catch plate 21h may be set according to practical requirements, and is not limited to the shape in fig. 6 b.

In addition, the lift platform 22b2 may be tightened by tightening bolts 22d3 so that the lift platform 22b2 is at the proper height.

The vehicle-mounted projection device provided by the embodiment can be adapted to vehicle types with different trunk structures by adjusting the optical axis angle of the projection mechanism and the height of the projection mechanism.

It should be noted that the embodiment shows only one solution for adjusting the height and angle of the projection mechanism, and there are many variations of this solution in practical use. For example, a crescent hole may be formed in the side wall of the support 22b so that the projection mechanism is fastened by a fastening shaft provided on the crescent hole. When the fastening shaft moves in the crescent hole, the angle of the optical axis of the projection mechanism relative to the horizontal plane can be adjusted. As another example, it is also possible to omit the tightening mechanism 22d by using a latch structure, and achieve more stable adjustment.
