The specific implementation mode is as follows:
in order to clearly illustrate the technical features of the present invention, the present invention is explained in detail by the following embodiments in combination with the accompanying drawings.
The utility model discloses an embodiment is as shown in fig. 1-6, a device is backed up to truck collision seat, be in including driver's cabin 1 and setting seat 2 in the driver's cabin 1, seat 2 with driver's cabin 1 is along truck fore-and-aft direction sliding connection, 2 bottoms of seat are equipped with and stretch into iron axle 3 of driver's cabin 1 downside, the diapire of driver's cabin 1 is formed with the confession iron axle 3 gliding logical groove, the device of backing up still includes: the energy storage part is arranged at the lower side of the cab 1 and is connected with the iron shaft 3 and the cab 1 so as to provide backward sliding power for the seat 2; a cab front panel bracket 4 provided on the front side of the cab 1, the cab front panel bracket 4 having a gap with the front wall of the cab 1, the cab front panel bracket 4 being slidably connected to the cab 1; the locking subassembly, set up in driver's cabin front panel support 4 with between the iron axle 3, include with the unblock piece that driver's cabin front panel support 4 links to each other, with the locking piece that driver's cabin 1 links to each other, the locking piece has the locking the first state of iron axle 3 and release the second state of iron axle 3, driver's cabin front panel support 4 can be relative 1 backsliding of driver's cabin is so that the unblock piece touches the locking piece switches to the second state.
The utility model discloses a device is retreated to truck when the truck normally traveles, is in the first state of place iron axle 3 through the locking piece, and at this moment, under the backward pulling force effect of energy storage piece, iron axle 3 is fixed, and seat 2 is fixed in driver's cabin 1 this moment. When the truck bumps, cab front panel support 4 receives dress impact, cab front panel support 4 moves cab front panel support 4 relatively cab 1 backward and drives the deblocking piece and touch the locking piece and switch over to the second state, and then can release iron shaft 3, under the effect of energy storage spare pull backward, can pull seat 2 backward, when making the front side position of cab 1 receive the striking deformation, cab 1 moves backward and can form and dodge, prevent that personnel from being extruded, the striking injures and deaths, especially prevent that the steering wheel from catching passenger's chest.
As shown in the figure, seat 2 is slidably disposed on a slide rail, and iron shaft 3 extends upward from the bottom of cab 1 into cab 1 and is connected to seat 2.
The utility model discloses a driver's cabin 1 can with bottom girder lug connection for the structural component stable in structure that driver's cabin 1 stable in structure especially driver's cabin 1 was drawn forth, for example structural component such as brake cable, gear change.
Furthermore, the utility model discloses only need on current driver's cabin 1 basis, set up in driver's cabin 1 bottom supply the iron axle 3 remove the logical groove can, simple structure is convenient, does not influence other structural component that set up driver's cabin 1.
It should be noted that, in order to enable the seat to move backwards in the cab, a space for the seat to move backwards is reserved in the cab, the length of the through groove formed by the bottom wall of the cab is preferably 40-50 cm, in a preferred embodiment, a sleeping berth is reserved on the rear side in the cab, and the sleeping berth can be formed as a reserved space for the seat to move backwards, and only the sleeping berth needs to be folded when the sleeping berth is not used.
Further specifically say, energy storage spare includes energy storage spring 5, the rear end of iron axle 3 is equipped with a wire rope 6, wire rope 6 deviates from the one end of iron axle 3 is equipped with dog 7 the bottom of driver's cabin 1 is equipped with the confession first support 8 that wire rope 6 passed, energy storage spring 5 cover is established wire rope 6's the outside, just energy storage spring 5's both ends respectively with dog 7 with first support 8 butt. By adopting the steel wire rope 6, other structural components on the lower side of the cab 1 can be avoided conveniently, only the guide ring 15 for guiding needs to be arranged at the bottom of the cab 1, and as shown in the figure, the steel wire rope 6 on the front side of the iron shaft 3 penetrates through the guide ring 15 connected with the bottom of the cab 1 to play a guiding role.
It should be noted that the present invention is applicable to trucks, especially flat-head trucks, and the lower end of the iron shaft 3 extends to the lower side of the cab 1, so that the iron shaft 3 and the wire rope 6 do not interfere with structural components in the cab 1, especially with structural components at the instrument panel.
The further optimization point is that a second support 9 is further arranged on one side of the first support 8, the steel wire rope 6 penetrates through the first support 8 from front to back and then penetrates through the second support 9 from back to front, and the energy storage spring 5 is arranged on the front side of the second support 9. Whereby the length of the cab 1 can be utilized. As shown in the figure, the first support 8 and the second support 9 are both fixed blocks with rope holes, and the first support 8 and the second support 9 are both connected with a girder at the bottom of the cab 1, so that the reversing function is realized, and the energy storage spring 5 can be integrally positioned at the lower side of the cab 1. In an alternative embodiment, the first bracket 8 and the second bracket 9 may also be provided in the form of guide wheels.
More specifically, the iron shaft 3 is connected with a locking pin 10 through a steel wire rope 6, and a locking end 11 is formed at the front end of the locking pin 10; the locking piece comprises two opposite locking blocks 12 and locking springs 13 respectively arranged on the outer sides of the two locking blocks 12, a truncated cone-shaped locking cavity is formed between the two locking blocks 12 in a matched mode, the locking end 11 extends into the locking cavity, the locking springs 13 are respectively arranged on the outer sides of the two locking blocks 12, and the two locking springs 13 tightly push the two locking blocks 12 to clamp the locking end 11; the unlocking piece comprises a conical top block 14 connected with the cab front panel bracket 4, and the conical top block 14 can push the two locking blocks 12 open to release the locking end 11.
Further specifically speaking, both ends of the cab front panel support 4 are respectively provided with a connecting rod 16, the front side of the cab 1 is provided with a connecting plate 17, one end of the connecting rod 16 far away from the cab front panel support 4 penetrates the connecting plate 17 and is connected with a limiting rib 18, and a limiting spring 19 is sleeved on the outer side of the connecting plate 17 and the connecting rod 16 between the cab front panel support 4.
The seat is further optimized in that the seat 2 is provided with a convex locking piece 20, a non-return locking piece 21 is arranged in the cab 1, when the seat 2 slides backwards, the locking piece 20 can push through the non-return locking piece 21, and the non-return locking piece 21 limits the forward movement of the locking piece 20. Therefore, after the seat 2 is pulled backwards by the energy storage piece, the seat 2 is prevented from moving forwards again, and the seat 2 is prevented from swinging back caused by vibration of the energy storage spring.
Further specifically say, non return locking piece 21 is the wedge, non return locking piece 21 the front end with driver's cabin 1 is articulated, the device of retreating still includes non return spring 22, non return spring 22 both ends respectively with non return locking piece 21 the rear end with driver's cabin 1 butt, driver's cabin 1 be formed with non return muscle 23 of non return locking piece 21 butt, non return muscle 23 restriction non return locking piece 21 to the rotation of locking piece 20 direction.
The above-mentioned specific embodiments can not be regarded as the restriction to the scope of protection of the utility model, to technical personnel in this technical field, it is right the utility model discloses any replacement improvement or transform that embodiment made all fall within the scope of protection of the utility model.
The parts of the present invention not described in detail are the known techniques of those skilled in the art.
