Description

Technical Field

[0001] The utility model relates to the technical field of automobile and seat structures, in particular to a locking structure for an armored vehicle seat. Background Art

[0002] Armored vehicles are various tracked or wheeled military vehicles with armored protection. They are a general term for armored military or police vehicles. Since armored vehicles are often used in off-road environments and the space inside armored vehicles is small, both the upper and lower seats often need to be adjusted.

[0003] The existing patent (publication number is CN220281182U) and a locking structure of a seat slide rail. The pressure of the spring on the slide rod in this patent causes the connecting plate to drive the cover plate to pull up the support rod, so that the latch tooth is stuck in the lock hole, which plays a role in stopping sliding. The handle is connected to the slide rod. Pulling the handle upward will cause the spring to contract, so that the slide rod pulls up the connecting plate, and the cover plate will cover the support rod downward. The support rod moves downward to push the latch tooth out of the lock hole, and the upper and lower slide rails can slide, so that the seat can be adjusted. However, the spring will become fatigued after being stretched for a long time. The fatigued spring will affect the slide rail effect of the seat. If rust occurs between the latch tooth and the lock hole, it will cause the latch tooth and the lock hole to rust, making the seat difficult to adjust.

[0004] Therefore, we propose an armored vehicle seat locking structure, which is conducive to ensuring the stability of the seat locking structure during long-term use, avoiding mechanical fatigue affecting the sliding effect of the seat, and avoiding mechanical rust that causes the seat to get stuck and unable to slide.

[0020] The technical solution of the present invention will be clearly and completely described below in conjunction with the drawings in the present invention. In addition, the forms of the various structures recorded in the following embodiments are merely illustrative, and the structures involved in the present invention are not limited to the various structures recorded in the following embodiments. All other implementations obtained by ordinary technicians in this field without making creative work belong to the scope of protection of the present invention.

[0021] Example:

[0022] See also Figure 1-4 The utility model provides a technical solution: since the driving environment of armored vehicles is relatively complex and the space inside armored vehicles is small, it is often necessary to adjust the position of the seats when getting on and off armored vehicles, so the armored vehicle seats need to be adjusted frequently. A locking structure for armored vehicle seats includes a base 1, a slide seat 2 is slidably installed at the bottom of the base 1, racks 4 are symmetrically arranged on the left and right sides of the inner wall of the base 1, and the protruding parts of the racks 4 are inclined. A horizontal support rod 6 is arranged inside the slide seat 2, and the right end of the support rod 6 is connected to a handle 3 through a rotating shaft 7, and a lock hook 5 is fixed to the left end of the support rod 6, and the lock hook 5 corresponds to the narrow surface lock buckle of the protruding part of the rack 4 , by lifting the handle 3, the handle 3 drives the support rod 6 to tilt up through the rotating shaft 7, and then the lock hook 5 and the rack 4 are disengaged, and then the handle 3 is lowered, and then the handle 3 lowers the support rod 6 through the rotating shaft 7, and then the lock hook 5 corresponds to the narrow surface lock of the protruding part of the rack 4, ensuring that the locking structure of the seat is stable during long-term use, and avoiding mechanical fatigue from affecting the sliding effect of the seat. When the sliding seat 2 and the base 1 slide, the lock hook 5 slides along the rack 4, and the lock hook 5 slides in a single direction along the wide surface of the protruding part of the rack 4, and the unidirectional sliding of the lock hook 5 is not restricted by the rack 4, and when the lock hook 5 slides in a certain direction, the lock hook 5 corresponds to the narrow surface lock of the protruding part of the rack 4 and is fixed.

[0023] Among them, a support plate 8 is arranged under the two groups of the racks 4, and the support plate 8 is fixed to the inner wall of the base 1, and pulleys 9 are arranged on the left and right sides of the slide 2. The distance between the racks 4 and the support plate 8 is greater than the diameter of the pulley 9. The pulley 9 is supported by the support plate 8, and then the pulley 9 rotates on the support plate 8, and then the rotation of the pulley 9 drives the slide 2 to move.

[0024] Among them, the left and right groups of pulleys 9 are located on the two groups of support plates 8 and roll, and the slide 2 moves on the support plate 8 through the pulleys 9. The pulleys 9 on the left and right sides of the slide 2 are supported on the support plates 8 accordingly, and then the pulleys 9 roll on the support plates 8, and then the slide 2 slides on the base 1, and then the slide 2 moves on the base 1, so as to avoid the seat being stuck and unable to slide due to mechanical rust.

[0025] Among them, the handle 3 is raised to make the support rod 6 tilt up with the rotating shaft 7 as the center point, and the tilting of the support rod 6 drives the locking hook 5 to disengage from the rack 4. By lifting the handle 3, the handle 3 drives the support rod 6 to tilt up through the rotating shaft 7, and then the locking hook 5 and the rack 4 are disengaged.

[0026] Among them, the handle 3 and the support rod 6 are connected by a torsion spring 10, and the torsion spring 10 pushes the handle 3 and the support rod 6 to open. The torsion spring 10 is made of an elastic material with soft material and high toughness, which can store force for twisting or rotation. When there is no external force, the torsion spring 10 is in a natural state and presents an initial shape. Once an external force is applied to the spring, the torsion spring 10 will be torsionally deformed, and the angle between the handle 3 and the support rod 6 is opened by the torsion spring 10, and then the handle 3 and the support rod 6 are rotated through the rotating shaft 7, and then the torsion spring 10 engages the support rod 6 and the lock hook 5 with the corresponding rack 4. By lifting the handle 3, the angle between the handle 3 and the support rod 6 becomes smaller, and then the support rod 6 is also tilted up, and then the lock hook 5 is separated from the rack 4.

[0027] Among them, there are two groups of support rods 6, the bottom end of the handle 3 is connected to the two groups of support rods 6 through two groups of rotating shafts 7 corresponding to the two groups of support rods 6, the two groups of support rods 6 correspond to the rack 4, and the locking hooks 5 of the two groups of support rods 6 are engaged and fixed to the rack 4.

[0028] The working principle of the embodiment of the utility model is as follows: the pulleys 9 on the left and right sides of the slide seat 2 are supported on the support plates 8 correspondingly, and then the pulleys 9 roll on the support plates 8, and then the slide seat 2 slides on the base 1, and by lifting the handle 3, the handle 3 drives the support rod 6 to tilt up through the rotating shaft 7, so that the angle between the handle 3 and the support rod 6 becomes smaller, and then the support rod 6 also tilts up, and then the locking hook 5 disengages from the rack 4, and then the handle 3 is lowered, the handle 3 and the support rod 6 are stretched apart by the torsion spring 10, and then the handle 3 is lowered by the rotating shaft 7, and then the locking hook 5 is locked with the narrow surface of the protruding part of the rack 4. When the slide seat 2 and the base 1 slide, the locking hook 5 slides along the rack 4, and the locking hook 5 slides in a single direction along the wide surface of the protruding part of the rack 4, and the unidirectional sliding of the locking hook 5 is not limited by the rack 4, and when the locking hook 5 slides in a certain direction, the locking hook 5 is locked and fixed with the narrow surface of the protruding part of the corresponding rack 4.
