The utility model provides a technical principle of adjustable high formula mortise lock as follows:
the adjustable height mortise lock comprises: a fixed part; the guide part is fixedly connected with the fixing part; the latch part is connected with the guide part in a sliding way; one end of the connecting part is fixedly connected with the mortise lock part; the power part is connected with the guide part and the other end of the connecting part; when the power part is started, the plug-in lock part is pulled by the connecting part to slide towards the top end of the fixing part along the guide part, so that the plug-in lock height adjusting function of the height-adjustable plug-in lock is realized.
Example one
The present embodiment provides an adjustable height mortise lock, comprising:
a fixed part;
the guide part is fixedly connected with the fixing part;
the latch part is connected with the guide part in a sliding way;
one end of the connecting part is fixedly connected with the mortise lock part;
the power part is connected with the guide part and the other end of the connecting part;
when the power part is started, the plug-in lock part is pulled by the connecting part to slide towards the top end of the fixing part along the guide part, so that the plug-in lock height adjusting function of the height-adjustable plug-in lock is realized. The mortise lock height adjusting function is that when the mortise lock slides towards the top end of the fixing part, the mortise lock drives the safety belt connected with the mortise lock to move to the chest or the abdomen of a passenger so as to prevent the passenger from being hurt by the transverse rotation of the body in an accident.
The height adjustable mortise lock provided by the present embodiment will be described in detail with reference to the drawings. Please refer to fig. 1, which is a schematic diagram of a height-adjustable mortise lock according to an embodiment of the present invention. As shown in fig. 1, the adjustable height mortise lock includes: a fixed part 101, a guide part 102, a latch part 103, a connecting part 104, and a power part 105.
Fixed part 101 is the installing support, the installing support and the back of the chair 106 and seat support 107 fixed connection of a seat, the fixed connection mode includes: bolt fastening, weld fastening and/or adhesive fastening.
The guide part 102 is a sliding guide rail and is fixedly connected with the mounting bracket.
The latch 103 is a latch slidably connected to the slide rail, and has a locking groove, which is engaged with the rail of the slide rail, is slidable, and is connected to the seat belt 115 to restrain the movement of the occupant.
The connecting portion 104 is a mortise lock connecting rod, and one end of the mortise lock connecting rod is fixedly connected with the mortise lock, and is used for pulling the mortise lock upwards, so as to adjust the binding position of the safety belt to the human body.
The power part 105 is a moving piston, the lower end of the moving piston is fixedly connected with the sliding guide rail or the mounting bracket, or the lower end of the moving piston is connected with the upper end of the sliding guide rail and the mounting bracket in an integrated manner, and the upper end of the moving piston is connected with the other end of the mortise lock connecting rod. A through hole 113 is formed in the middle of the lower end of the moving piston, and the mortise lock connecting rod penetrates through the through hole 113 to be connected with the mortise lock and the upper end of the moving piston.
The lower end of the moving piston is fixedly connected to a first gas generator 108 and a second gas generator 110. The first gas generator 108 is provided with a first chamber and a first exhaust passage 112, gunpowder is arranged in the first chamber, and a first ignition harness 109 is fixedly connected with the first chamber; the second gas generator 110 is provided with a second chamber in which powder is provided and to which a second ignition harness 111 is fixedly connected, and a second exhaust passage 114. When the first ignition wire bundle 109 works alone, the first gas generator 108 generates gas to push the connecting part 104 and pull the latch part 103 to move upwards, so that the electric plug is suitable for a small human body (such as a female); when the first ignition harness 109 and the second ignition harness 111 work simultaneously, the first gas generator 108 and the second gas generator 110 generate gas simultaneously, and the amount of the generated gas can be adjusted by the amount of the ignition charge in the second gas generator 110, so that the connecting part 104 is pushed and the latch part 103 is pulled to move upwards, and the latch is suitable for a human body with a large size (such as a male person), and different latch height position control can be realized for passengers with different sizes.
The working process of the height-adjustable mortise lock is as follows:
when the automobile is not subjected to side collision, the latch part 103 is at the lowest position, and plays a role in basically protecting passengers; when the automobile is in side collision, the passenger rotates laterally, so that collision is dangerous, the power part 105 starts to work, the latch part 103 is pulled by the connecting part 104 to slide upwards along the guide part, and the safety belt 115 is lifted to the chest or the belly of the passenger by the latch part 103.
Specifically, the height-adjustable mortise lock adjusts the position state of the seat according to the height condition of the passenger or performs different ignition operations according to the action of the weight of the passenger on the seat. When the position of the automobile seat is adjusted backwards or downwards or the current load bearing of the automobile seat is larger, the passenger can be determined to be larger in size, and a two-stage ignition device is required. The first ignition wire bundle 109 ignites gunpowder in the first chamber, gas is generated through chemical reaction, and the gas pushes the upper end of the moving piston to move upwards through the first exhaust passage 112; meanwhile, the second ignition wire harness 111 ignites gunpowder in the second chamber, gas is generated through a chemical reaction, the gas pushes the upper end of the moving piston to move upwards through the second exhaust channel 114, and the moving piston drives the mortise lock to slide upwards to a higher position through the combined action of the two-stage ignition gas, so that the safety belt 115 is bound to the chest and abdomen of a large passenger, and the injury caused by the secondary collision of the passenger is reduced. When the position of the automobile seat is adjusted forwards or upwards or the current load of the automobile seat is small, the size of the passenger can be determined to be small, only a single-stage ignition device is needed, gunpowder in the first cavity can be ignited through the first ignition wire harness 109, gas is generated through chemical reaction, the gas pushes the upper end of the moving piston to move upwards through the first exhaust channel 112, and the moving piston drives the mortise lock to slide upwards to a lower position due to less gas generated by single-stage ignition, so that the safety belt 115 is bound to the chest and abdomen of the passenger with the small size, and the injury caused by secondary collision of the passenger is reduced.
To sum up, adjustable high formula mortise lock can solve and drive the safety belt through the mortise lock and improve to human belly or chest in the side direction collision, can tie up the human body betterly, reduces the human amount of exercise to the opposite side to avoid between the passenger or passenger and automotive interior to lead to the fact the injury between the hard thing. The utility model discloses effectively overcome all kinds of shortcomings in the prior art and had high industry value.
The above embodiments are merely illustrative of the principles and effects of the present invention, and are not to be construed as limiting the invention. Modifications and variations can be made to the above-described embodiments by those skilled in the art without departing from the spirit and scope of the present invention. Accordingly, it is intended that all equivalent modifications or changes which may be made by those skilled in the art without departing from the spirit and technical spirit of the present invention be covered by the claims of the present invention.
