Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of vehicle driver's mirror lifting and lowering, and in particular to a vehicle driver's mirror resetting and lifting device. Background Art
[0002] To meet future combat requirements, combat vehicle weaponry is trending toward lighter weight and smaller size, while also meeting transportability requirements by rail, sea, and air. Traditional turret weapon systems often lack the ability to lower their maximum height due to the mounting of observation devices (such as the commander's scope and gunner's scope) on the turret roof. This makes them inadequate for transport, especially when transporting empty equipment by air. Some turret weapon systems utilize retractable or simple lifting mechanisms to allow the observation device to switch between combat and mobile positions, meeting the requirements of small transport size and a high field of view during combat. The main drawback of current retractable and simple lifting mechanisms is poor reset accuracy. When the mechanism switches from mobile to combat, the actual position of the observation device is difficult to reconcile with the previous accurate position (primarily in height), thus affecting the accuracy of the optical sight.

DETAILED DESCRIPTION
[0013] like Figures 1 to 7As shown, a vehicle driver's mirror reset and lifting device includes a lifting platform assembly a, a fixed platform assembly b, and a drive unit c. The drive unit c includes a left electric cylinder 8 and a right electric cylinder 10, which are connected by a coupling 11. A lifting motor 9 is provided at the front end of the left electric cylinder 8. The fixed platform assembly b includes a locking cylinder 7 mounted above the left and right electric cylinders. The upper end of the inner cylinder wall of the locking cylinder 7 is connected to a fixed seat ring 3. Intermittent threads 7-1 are provided on the upper and lower ends of the inner wall of the locking cylinder 7. The outer circumference of the seat ring 3 is provided with threads corresponding to the intermittent threads 7-1, and the seat ring 3 is mounted on the intermittent threads 7-1 of the locking cylinder 7. The lower end surface of the seat ring 3 is connected and fixed to a locking reducer 5. The main gear in the locking reducer 5 meshes with a ring gear 4. The ring gear 4 is connected and fixed to the outer circumference of the seat ring 3 by screws. The locking reducer 5 is fixed to the lower end surface of the seat ring 3 by bolts. The locking reducer 5 is provided with a locking motor. The upper end surface of the ring 3 is installed with the support tube mounting base plate 2 in the lifting platform assembly a. The upper end surface of the support tube mounting base plate 2 is connected and fixed to the support tube 1. The support tube 1 is connected and fixed to the support tube mounting base plate 2 by bolts. A support plate 6 is set on the circumference of the bottom outer wall of the support tube 1. The piston rods of the left and right electric cylinders pass through the support plate 6 and are connected and fixed to the upper end flange of the support tube 1. The vehicle length mirror 12 is connected and fixed to the flange at the upper end of the support tube 1. A vehicle length mirror through-line hole 2-1 that axially passes through the support tube mounting base plate 2 is set in the center of the support tube mounting base plate 2. A plurality of weight-reducing blind holes 2-2 are set on the circumference of the lower end surface of the support tube mounting base plate 2.
[0014] When the vehicle length mirror reset and lifting device is working, the locking motor first drives the outer ring of the seat ring to rotate through the locking reducer and the tooth arc, so as to realize the "locking" or "disengaging" state of the intermittent thread between the outer ring of the seat ring and the locking cylinder. When the intermittent thread is in the "disengaging" state, the lifting drive motor drives the lifting platform combination to lift and lower through the left and right electric cylinders. After the lifting platform combination reaches the specified height, the locking motor drives the outer ring of the seat ring to rotate, so that the intermittent thread between the outer ring of the seat ring and the locking cylinder is in the "locking" state, and the lifting platform combination realizes reliable lifting and resetting.
[0015] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications made to the present invention by those skilled in the art without departing from the spirit of the present invention shall fall within the scope of protection of the present invention.
