Therefore, the first component, region, layer, and / or part discussed below may be referred to as the second component, region, layer, and / or part without departing from some embodiments of the present invention.
[0040] As described above, due to the very compact structure of the whole vehicle and the very narrow cabin, when reinstalling and disassembling the in-cabin equipment, it is extremely inconvenient, time-consuming, and laborious to disassemble and assemble the screws placed inside the cabin.
[0041] To overcome the above-mentioned defects existing in the prior art, the present invention provides a fastening device for loading and unloading in-cabin equipment, which can simplify the installation and disassembly process of in-cabin equipment and improve the disassembly and assembly efficiency of in-cabin equipment.
[0042] Please refer to Figure 1 , Figure 1 which shows a side schematic view of a fastening device for loading and unloading in-cabin equipment provided according to some embodiments of the present invention.
[0043] As Figure 1 shown, the fastening device 100 for loading and unloading in-cabin equipment includes an in-cabin equipment 110, and the installation surface A of the in-cabin equipment 110 is fixedly integrated with a connecting plate 120.
[0044] When the in-cabin equipment 110 is installed and fixed inside the cabin, the outside of the surface B of the in-cabin equipment 110 can be the outside of the cabin, and the position of the in-cabin equipment 110, that is, the inside of the surface B, is the inside of the cabin.
[0045] The fastening device 100 for loading and unloading in-cabin equipment further includes an inner base 130 and an outer base 140. The inner base 130 and the outer base 140 are fixed to the installation surface of the cabin. The inner base 130 is used to fix the inside of the in-cabin equipment 110 to the cabin installation surface, and the outer base 140 can be arranged close to the outside of the cabin.
[0046] The connecting plate 120 can be detachably and firmly connected to the outer base 140 close to the outside of the cabin through a first fastener. The outer base 140 can be a right-angled base close to the outside of the cabin, with the right-angled bottom surface fixed to the cabin installation surface and the right-angled side surface used to connect with the connecting plate 120.
[0047] Preferably, the connecting plate 120 may further have a first connecting portion 121, and the first connecting portion 121 conforms to the surface of the outer base 140 for connection, so as to make the connection between the connecting plate 120 and the outer base 140 more stable. InFigure 1 In the illustrated embodiment, the connecting surface of the outer base 140 is the right-angled side surface. The first connecting portion 121 can be flush with the surface B of the in-cabin device 110, facilitating the loading and unloading of the in-cabin device 110 by technicians outside the cabin.
[0048] The first connecting portion 121 and the connecting surface of the outer base 140 are tightly connected by a first fastener. Figure 1 In the illustrated embodiment, threaded holes for tightly connecting the first fastener can be formed on the connecting surface of the outer base 140, and the first fastener can be a tension screw 150. The tension screw 150 is passed through the first connecting portion 121 of the connecting plate 120 and the threaded holes on the connecting surface of the outer base 140, so that the connecting plate 120 and the outer base 140 near the outside of the cabin are detachably and tightly connected.
[0049] Optionally, in some other embodiments, those skilled in the art can also, based on the above concept, adopt other equivalent components to achieve the effect of detachable and tight connection. For example, the first fastener can also be set as a buckle, a hook, etc. Correspondingly, a buckle device for clamping the first fastener can also be provided on the outer base.
[0050] The connecting plate 120 can also be detachably and tightly connected to the inner base 130 near the inside of the cabin through a self-locking structure. Preferably, the connecting plate 120 can have a second connecting portion 122 extending towards the inside of the cabin, and the second connecting portion 122 is inserted into the inner base 130 to form a self-locking structure.
[0051] In Figure 1 the illustrated embodiment, the self-locking structure can be composed of a semi-circular plate and a clamping member. For details, please refer to Figure 2A and Figure 2B , Figure 2A shows a schematic diagram of the self-locking structure in the unlocked state according to some embodiments of the present invention, Figure 2B shows a schematic diagram of the self-locking structure in the locked state according to some embodiments of the present invention.
[0052] As Figure 2A and Figure 2BAs shown, a rotatable semicircular plate 131 is provided inside the inner base 130, and the second connecting portion of the connecting plate 120 can be a clamping member 1221 with a rough surface, and the clamping member 1221 can press the lower part of the semicircular plate 131 of the inner base 130 to form a self-locking structure. When the clamping member 1221 on the second connecting portion 122 is inserted into the semicircular plate 131 in the inner base 130, the end of the semicircular plate 131 that is tilted and falls on the bottom of the inner base 130 is lifted. The semicircular plate 131 uses the principle of a lever to convert the lateral thrust into a downward clamping pressure to press the clamping member 1221, thereby achieving the locking of the connecting plate 120 and the inner base 130. When the clamp 1221 on the second connecting portion 122 is pulled out from the semicircular plate 131 in the inner base 130, the semicircular plate 131 releases the clamp 1221, and drops the pulled-out end of the clamp 1221 back to the bottom of the inner base 130, and lifts up the other end of the semicircular plate 131, so that the clamp 1221 is smoothly pulled out of the inner base 130, thereby achieving the unlocking of the connecting plate 120 and the inner base 130.
[0053] Optionally, in another embodiment, the self-locking structure may be composed of a circular hole and a cone. Figure 3 , Figure 3 A schematic diagram of a self-locking structure provided according to some embodiments of the present invention is shown.
[0054] like Figure 3 As shown, the inner base 300 may be as shown in FIG. Figure 1 The right-angled base similar to the outer base 140 in the illustrated embodiment has a circular hole 310 on the right-angled side of the inner base 300. The second connecting portion of the connecting plate can be a cone 320 adapted to the circular hole 310. The inner base 300 and the connecting plate are locked by inserting the cone 320 into the circular hole 310 and clamping at a position where the cone 320 and the circular hole 310 have the same diameter. Correspondingly, the connecting plate and the inner base 300 are unlocked by pulling the cone 320 out of the circular hole 310.
[0055] Please refer to Figure 1 and Figure 4 , Figure 4 A front schematic diagram of a fastening device for loading and unloading cabin-built equipment provided according to some embodiments of the present invention is shown.
[0056] like Figure 1 and Figure 4As shown in the figure, the front surface of the in-cabin device 110 is the surface B of the in-cabin device 110. The in-cabin device 110 can set the number of required bases according to its own size, weight and other conditions. Multiple inner bases 130 and outer bases 140 are symmetrically distributed on both sides of the in-cabin device 110. The in-cabin device 110 can be provided with two symmetrical bases 411 and 412. Here, both the base 411 and the base 412 include an inner base 130 close to the inside of the cabin and an outer base 140 close to the outside of the cabin. For another example, when the in-cabin device 110 is small in volume, the number of bases can be only one. When the in-cabin device 110 is relatively large in volume, the number of bases can also be increased adaptively.
[0057] Please continue to refer to Figure 1 , the mounting surface A of the in-cabin device 110 can be connected to the connecting plate 120 through fastening screws 160 to be fixed as a whole. There can be one fastening screw 160 on each side of the connecting plate 120, one close to the outside of the cabin and the other close to the inside of the cabin, so as to stably fix the connecting plate 120 and the in-cabin device 110 as a whole. In addition, those skilled in the art can, based on the above concept, adopt other equivalent components to achieve the effect of fixing the mounting surface A of the in-cabin device 110 and the connecting plate 120.
[0058] By fixing the in-cabin device 110 and the connecting plate 120 as a whole, and the fastening connection between the connecting plate 120 and the inner base 130 and the outer base 140, the fastening device 100 for loading and unloading the in-cabin device provided by the present invention can install the connecting plate 120 together with the in-cabin device 110 inside the cabin, and convert the bolt connection between the in-cabin device 110 and the cabin mounting surface into the fastening connection between the connecting plate 120 and the inner base 130 and the outer base 140.
[0059] In this way, technicians can load and unload the in-cabin device by disassembling and assembling the first fastener outside the cabin. For example, in Figure 1 the shown embodiment, after the technician disassembles the tensioning screw 150 outside the cabin and pulls out the connecting plate 120 outside the cabin, the self-locking structure of the inner base 130 is changed from the locked state to the unlocked state. In this way, the in-cabin device 110 is disassembled from the inside of the cabin together with the connecting plate 120.
[0060] In summary, the fastening device for loading and unloading the in-cabin device provided by the present invention can disassemble and assemble the in-cabin device outside the cabin through the first fastener, simplifies the loading and unloading process of the in-cabin device, and greatly improves the loading and unloading efficiency of the in-cabin device.
