Description

Technical Field

[0001] This utility model relates to the field of shield technology, and in particular to a retractable shield. Background Technology

[0002] With the continuous advancement of modern policing and military equipment, the design and function of shields, as an important protective tool, are constantly evolving. Traditional shields typically employ a fixed-size design, which to some extent limits the user's flexibility and adaptability. For example, a fixed shield size may not provide optimal protection when facing different types of threats. In confined spaces, an overly large shield may hinder the user's movement, while in open areas, a small shield may not provide sufficient protection. Furthermore, different combat environments and mission requirements necessitate shields with greater adjustability and adaptability. However, traditional shield designs lack this flexibility, failing to freely adjust the shield size according to actual needs, thus impacting the user's combat efficiency and safety.

[0047] The specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit the scope of this utility model.

[0048] like Figure 1 , Figure 2As shown, the retractable shield provided in this embodiment includes: a fixed shield 100, a retractable shield assembly 200, a mounting base 300, and a drive assembly 400; the side of the fixed shield 100 away from the impact-resistant surface is connected to the mounting base 300, and there is an accommodating space between the fixed shield 100 and the mounting base 300 for placing the retractable shield assembly 200; the drive assembly 400 is disposed on the mounting base 300, and the drive assembly 400 is pulsatorically connected to the retractable shield assembly 200. The drive assembly 400 is configured to drive the retractable shield assembly 200 to extend from or into the accommodating space to increase or decrease the impact-resistant area. When it is necessary to increase the shield area, the drive assembly 400 drives the retractable shield assembly 200 to extend from the accommodating space to increase the shield area; when it is necessary to reduce the shield area, the drive assembly 400 drives the retractable shield assembly 200 to extend into the accommodating space to reduce the shield area.

[0049] The mounting base 300 is equipped with a tactical rail 500, which is a metal rail used to freely add or remove accessories, such as flashlights and sensors.

[0050] The retractable shield provided in this embodiment, through the cooperative arrangement of the retractable shield assembly 200 and the drive assembly 400, utilizes the driving force generated by the drive assembly 400 to move the retractable shield assembly 200 relative to the fixed shield 100, causing the retractable shield assembly 200 to extend from or into the accommodating space, thereby increasing or decreasing the overall impact-resistant area of ​​the shield. Furthermore, a tactical guide rail 500 is configured on the mounting base 300, which allows for the selective installation of other accessories, making it more versatile and alleviating the technical problem in the prior art where traditional shields typically use a fixed size design, making it impossible to freely adjust the shield area according to actual conditions.

[0051] Based on the above embodiments, the telescopic shield assembly 200 in the telescopic shield provided in this embodiment further includes a left telescopic shield 210, a right telescopic shield 220, and a lower telescopic shield 230; the left telescopic shield 210, the right telescopic shield 220, and the lower telescopic shield 230 are all disposed in the accommodating space, the left telescopic shield 210 and the right telescopic shield 220 are disposed opposite to each other, and both telescopically move along the side of the fixed shield 100; the lower telescopic shield 230 telescopically moves perpendicular to the bottom edge of the fixed shield 100.

[0052] Specifically, the mounting base 300 includes a frame and a base plate. The frame extends with a connecting protrusion on the side near the fixed shield 100. The connecting protrusion connects with the fixed shield 100, thereby connecting the mounting base 300 and the fixed shield 100 into a whole. The gap between other parts of the frame and the fixed shield 100 is the accommodating space, which can accommodate the left telescopic shield 210, the right telescopic shield 220 and the lower telescopic shield 230.

[0053] Furthermore, such as Figure 3 As shown, the drive assembly 400 includes a first drive unit 410, a second drive unit 420, and a third drive unit 430; the first drive unit 410 is connected to the left telescopic shield 210; the second drive unit 420 is connected to the right telescopic shield 220; and the third drive unit 430 is connected to the lower telescopic shield 230. The driving directions of the first drive unit 410 and the second drive unit 420 are both to the side of the fixed shield 100, and the driving direction of the third drive unit 430 is perpendicular to the bottom edge of the fixed shield 100.

[0054] Specifically, the first drive unit 410 drives the left telescopic shield 210 to move along the side direction perpendicular to the fixed shield 100, and the second drive unit 420 drives the right telescopic shield 220 to move along the side direction perpendicular to the fixed shield 100, so that the left telescopic shield 210 and the right telescopic shield 220 can extend to both sides to expand the shield area, and can also retract to reduce the shield area.

[0055] Furthermore, the first drive unit 410 includes a first drive motor 411, a first rotating lead screw 412, and a first movable slider 413. The first drive motor 411 is fixed on the mounting base 300. The drive end of the first drive motor 411 is connected to the first rotating lead screw 412. The first movable slider 413 is threadedly connected to the first rotating lead screw 412 and is connected to the left telescopic shield 210. The driving force generated by the first drive motor 411 drives the first rotating lead screw 412 to rotate along its own axis. Since the first rotating lead screw 412 is threadedly connected to the first movable slider 413, the first movable slider 413 moves along the first rotating lead screw 412, thereby driving the left telescopic shield 210 to move relative to the fixed shield 100.

[0056] Furthermore, the first drive unit 410 also includes a first guide rail 414 and a first guide slider 415; the arrangement direction of the first guide rail 414 is parallel to the arrangement direction of the first rotating screw 412, the first guide slider 415 is slidably connected to the first guide rail 414, and the first guide slider 415 is connected to the left telescopic shield 210 so that the left telescopic shield 210 can move along the first guide rail 414. The first guide rail 414 and the first guide slider 415 play a guiding role, restrict the movement direction of the left telescopic shield 210, and ensure that the left telescopic shield 210 can telescopically move in a direction perpendicular to the side of the fixed shield 100.

[0057] Furthermore, the second drive unit 420 includes a second drive motor 421, a second rotating lead screw 422, and a second movable slider 423. The second drive motor 421 is fixed on the mounting base 300, and the drive end of the second drive motor 421 is connected to the second rotating lead screw 422. The second movable slider 423 is threadedly connected to the second rotating lead screw 422 and is connected to the right telescopic shield 220. The driving force generated by the second drive motor 421 drives the second rotating lead screw 422 to rotate along its own axis. Since the second rotating lead screw 422 is threadedly connected to the second movable slider 423, the second movable slider 423 moves along the second rotating lead screw 422, thereby driving the right telescopic shield 220 to move relative to the fixed shield 100.

[0058] Furthermore, the second drive unit 420 also includes a second guide rail 424 and a second guide slider 425; the arrangement direction of the second guide rail 424 is parallel to the arrangement direction of the second rotating screw 422, the second guide slider 425 is slidably connected to the second guide rail 424, and the second guide slider 425 is connected to the right telescopic shield 220 so that the right telescopic shield 220 can move along the second guide rail 424. The second guide rail 424 and the second guide slider 425 play a guiding role, restrict the movement direction of the right telescopic shield 220, and ensure that the right telescopic shield 220 can telescopically move in a direction perpendicular to the side of the fixed shield 100.

[0059] Furthermore, the third drive unit 430 includes a third drive motor 431, a third rotating lead screw 432, and a third moving slider 433. The third drive motor 431 is fixed on the mounting base 300, and the drive end of the third drive motor 431 is connected to the third rotating lead screw 432. The arrangement direction of the third rotating lead screw 432 is perpendicular to the arrangement direction of the first rotating lead screw 412, that is, the drive direction of the third drive motor 431 is perpendicular to the bottom edge of the fixed shield 100. The third moving slider 433 is threadedly connected to the third rotating lead screw 432 and is connected to the lower telescopic shield 230. The drive motor is used to drive the third rotating lead screw 432 to rotate along its own axis, so that the third moving slider 433 moves along the third rotating lead screw 432, thereby driving the lower telescopic shield 230 to telescopically move relative to the fixed shield 100.

[0060] Furthermore, in order to facilitate the connection between the left telescopic shield 210 and the first movable slider 413, a left connecting block is provided on the left telescopic shield 210. The left connecting block is connected to the first movable slider 413 by screws. Similarly, a right connecting block and a lower connecting block are provided on the right telescopic shield 220 and the lower telescopic shield 230, respectively, for connecting the second movable slider 423 and the third movable slider 433.

[0061] In addition, in order to limit the telescopic movement distance of the left telescopic shield 210 and prevent the left telescopic shield 210 from extending or retracting excessively, in an optional embodiment, a first proximity switch 416 and a second proximity switch 417 are provided in the mounting base 300, and a sensing component is provided on the first moving slider 413. When the sensing component contacts the first proximity switch 416 or the second proximity switch 417, a motor stop signal is issued, and the first drive motor 411 stops working. The distance between the first proximity switch 416 and the second proximity switch 417 is the movement distance of the left telescopic shield 210.

[0062] Similarly, other proximity switches can be installed on the mounting base 300 to limit the telescopic movement distance of the right telescopic shield 220 and the lower telescopic shield 230.

[0063] Furthermore, the tactical rail 500 is positioned on the side of the mounting base 300 away from the lower telescopic shield 230 to prevent the lower telescopic shield 230 from interfering with the installation of components onto the tactical rail 500.

[0064] In an optional embodiment, the retractable shield is also provided with a control mechanism, which may be a host computer 600, a microprocessor unit, or a control circuit board, etc. Preferably, the control mechanism is a host computer 600, which can be set on the mounting base 300, and a motor controller 700 is also set on the mounting base 300. The user uses the host computer 600 to control the operation of the drive motor through the motor controller 700, thereby controlling the retractable movement of the retractable shield assembly 200.

[0065] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
