[0035] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0036] During the driving process of movable equipment such as vehicles, a laser warning device can be used to warn the equipment's route and the required avoidance width during the transfer of the equipment. Taking vehicles as an example, the length, width, height and location of the laser warning device installed in vehicles of different models are generally different. The irradiation length or area of ​​the laser warning device of the same model generally remains constant, while the irradiation length or area of ​​the laser warning device projected on the outside of the vehicle required by different models of vehicles is also different. In the prior art, the light output display length or area of ​​the laser warning device is constant, and the versatility in different vehicles is poor. In order to make the length of the projected light meet the laser warning length requirements of different models of vehicles during driving, it is often necessary to design special laser warning devices for different models of vehicles, which greatly increases the research and development and production costs of the laser warning device.

[0037] To solve the above technical problems, Figures 1 to 8 As shown, the present application proposes a warning device 100 , which includes a base 110 , a laser module 120 and an adjustment component 130 .

[0038] like Figure 1 as well as Figure 5 As shown, the base 110 has a light exit hole 1111, and the light exit hole 1111 is used to limit the light exit of the laser module 120. The shape of the light exit hole 1111 can be different according to the different warning requirements of different mobile devices such as vehicles 200. Specifically, the light exit hole 1111 can be a circular hole, a rectangular hole, a star-shaped hole or a hole of any suitable shape, and the light exit hole 1111 can be a regular hole or an irregular hole, which is not limited here.

[0039] like Figure 1 as well as Figure 5As shown, the laser module 120 is connected to the base 110, and the laser module 120 can emit a warning laser 121 from the light outlet 1111 along the first direction X. In order to facilitate the display of the route of the vehicle 200 and the width of the path that needs to be avoided, the laser pattern projected on the ground by the laser module 120 can be a linear pattern, a triangular pattern or a rectangular pattern, etc. The pattern projection of the warning laser 121 on the ground indicates the driving path of the vehicle 200 and the width that needs to be avoided when the vehicle 200 is driving. Specifically, when the projected light is a straight line, the straight line can be parallel to the driving path of the vehicle 200 or perpendicular to the driving path of the vehicle 200. When the straight line is parallel to the driving path of the vehicle 200, the warning devices 100 on both sides respectively indicate the positions that need to be avoided on each side of the vehicle 200 during driving, and the distance between the warning lasers 121 on both sides is the total distance that the vehicle 200 is predicted to need to avoid. When the straight line is perpendicular to the driving path of the vehicle 200, the length of the straight line is the width that the vehicle 200 needs to avoid. At the same time, along the driving direction of the vehicle 200, the area between the straight line and the vehicle 200 is the avoidance area. If the shape projected by the warning laser 121 is a rectangle or other shape, the avoidance area can also be indicated by the boundary or pattern content of the projected laser pattern, which will not be repeated here. The warning device 100 can be set on both sides of the vehicle 200, or at the front or rear end of the vehicle 200, without limitation here.

[0040] like Figure 3As shown, the adjustment component 130 is connected to the base 110, the projection surface 131 is perpendicular to the first direction X, the adjustment component 130 has a first projection 132 on the projection surface 131 along the first direction X, the light exit hole 1111 has a second projection 112 on the projection surface 131 along the first direction X, the adjustment component 130 has a first state and a second state, in the first state, the first projection 132 and the second projection 112 have a first overlap area a, in the second state, the first projection 132 and the second projection 112 have a second overlap area b, and the first overlap area a and the second overlap area b satisfy: a>b. The warning laser 121 is emitted from the light exit hole 1111 along the first direction X, and the actual aperture size of the light exit hole 1111 directly affects the size of the display area of ​​the light exit of the laser module 120 on the target surface, and the target surface can be the ground, etc. When the projection of the light emitted by the laser module 120 on the target surface is a linear light, the actual diameter of the light emitting hole 1111 changes, and the length of the straight line projected by the warning laser 121 on the target surface also changes accordingly. Specifically, in the first state, the first projection 132 and the second projection 112 have a first overlap area a, that is, along the first direction X, the adjustment component 130 can block the light emitting hole 1111, and the actual blocking degree of the light emitting hole 1111 by the adjustment component 130 can be set according to the light emission warning requirements of the warning device 100 on vehicles 200 of different models. The adjustment component 130 can block any suitable opening area of ​​the light emitting hole 11111, such as 1 / 4, 1 / 3, 1 / 2 or 2 / 3. In the second state, the first projection 132 and the second projection 112 have a second overlap area b, and the first overlap area a and the second overlap area b satisfy: a>b. Similarly, in the second state, the adjustment component 130 can block any suitable area of ​​the light emitting hole 1111 opening. It should be noted that the first overlap area a is greater than the second overlap area b. Specifically, the second overlap area b may also be 0 mm. 2 , that is to say, the light exit hole 1111 has the largest light exit area. It can be understood that the first overlapping area a can also be the opening area of ​​the light exit hole 1111. At this time, the adjustment component 130 completely covers the light exit hole 1111, and the warning device 100 is in a closed state.

[0041] The technical solution of the present application can control the overlap area between the adjustment component 130 and the light exit hole 1111, thereby controlling the exit aperture of the warning laser 121 emitted from the light exit hole 1111, and finally controlling the projection area of ​​the warning laser 121 on the target surface. The overlap area between the adjustment component 130 and the light exit hole 1111 can be set according to the installation requirements of the warning device 100 on vehicles 200 of different models. The technical solution of the present application improves the versatility of the warning device 100 on vehicles 200 of different models, and greatly reduces the research and development and manufacturing costs of the warning device 100.

[0042] like Figure 1 , Figure 2 , Figure 5 as well as Figure 6 As shown, the way in which the adjustment component 130 covers and releases the light exit hole 1111 may vary according to different usage requirements. The adjustment component 130 may approach or move away from the light exit hole 1111 along a direction intersecting the first direction X, so that the overlapping area increases or decreases, and the light exit area of ​​the light exit hole 1111 decreases or increases accordingly. The adjustment component 130 may be provided with one light shielding plate, or may be provided with multiple light shielding plates, and the multiple light shielding plates share the light exit of the light hole. The light shielding plate 133 may be snap-connected to the base 110, and may slide or rotate relative to the base 110, as long as the light shielding plate 133 may approach or move away from the light exit hole 1111. The light shielding plate 133 may cooperate with a protrusion or a slot of the base 110 to achieve the connection between the light shielding plate 133 and the base 110, which is not limited here. In this embodiment, the base 110 has a first card slot 113, and the adjustment component 130 includes a light shielding plate 133, which is connected to the first card slot 113. The light shielding plate 133 can slide relative to the base 110 along the second direction Y, and the second direction Y intersects with the first direction X. Specifically, the light shielding plate 133 can be a rectangular plate, a cylindrical plate, a fan-shaped plate, or a plate of any other suitable shape. Correspondingly, the first card slot 113 can be a rectangular slot, etc. The first card slot 113 can also be connected to the light outlet hole 1111, and the light shielding plate is passed through the light outlet hole 1111 from the first card slot 113 along the second direction Y. The provision of the first card slot 113 can improve the stability of the movement and fixation of the light shielding plate relative to the base 110, thereby improving the light output stability of the warning laser 121.

[0043] The base 110 is provided with a light exit hole 1111, and the light shielding plate 133 can be provided on a side of the base 110 close to the laser assembly, or on a side of the base 110 away from the laser assembly. When in use, the user can directly push the light shielding plate 133 to switch between the first state and the second state. The warning device 100 can also be provided with a driving member 134 to drive the light shielding plate 133 to switch between the first state and the second state. Figure 3 as well as Figure 5 As shown, in this embodiment, the adjustment component 130 also includes a driving member 134, one side of the driving member 134 is connected to the base 110, and the other side is connected to the light baffle 133, and the driving member 134 is used to drive the light baffle 133 to switch from the first state to the second state along the second direction Y. The driving member 134 can be configured as an electrically controlled driving member 134, such as a servo motor, an electric push rod, a linear motor, an electrically controlled cylinder or an electromagnetic relay. The driving member 134 can also be a mechanical driving member 134, such as a ratchet, a snap ring 1341, a spring, etc. The setting of the driving member 134 can make the control of the light baffle 133 more accurate and convenient.

[0044] like Figure 3 as well as Figure 4 As shown, in this embodiment, the base 110 has a second card slot 114, and the second card slot 114 is arranged around an axis parallel to the first direction X. The light blocking plate 133 has a third card slot 1331, and the third card slot 1331 extends along the third direction Z. The third direction Z is perpendicular to the first direction X and intersects with the second direction Y. One end of the driving member 134 is clamped in the second card slot 114 and the other end is clamped in the third card slot 1331. The driving member 134 can slide along the second card slot 114, so that the end of the driving member 134 arranged in the third card slot 1331 drives the light blocking plate 133 to approach or move away from the light exit hole 1111 along the second direction Y. Specifically, the first card slot 113 can extend along the second direction Y, the light shielding plate 133 is arranged in the first card slot 113 along the second direction Y, the third direction Z intersects with the second direction Y, the light shielding plate 133 abuts against the wall surface of the first card slot 113, and under the limiting effect of the first card slot 113, when the driving member 134 rotates along the second card slot 114 around an axis parallel to the first direction X, one end of the driving member 134 that passes through the third card slot 1331 moves in the third card slot 1331, and at the same time drives the light shielding plate 133 to move in the first card slot 113 along the second direction Y. In other words, the movement of the driving member 134 along the second card slot 114 can be decomposed into the movement of the driving member 134 along the third card slot 1331 and the movement of the light shielding plate 133 along the second direction Y.

[0045] The driving member 134 may be a rod or a plate with a clamping portion at both ends, the base 110 is provided with a second clamping slot 114, and the light shielding plate 133 is provided with a third clamping slot 1331. The two ends of the driving member 134 may be clamped in the second clamping slot 114 and the third clamping slot 1331, respectively. It is understood that in some embodiments, the driving part may be provided with a clamping slot, and the base 110 and the light shielding plate 133 may be provided with a protrusion connected to the driving member 134, which will not be described in detail here. Figure 2 As shown, in this embodiment, the driving member 134 includes a snap ring 1341 and a connecting rod 1342. The snap ring 1341 is arranged around an axis parallel to the first direction X and penetrates the second clamping groove 114. One end of the connecting rod 1342 is connected to the snap ring 1341, and the other end is penetrated in the third clamping groove 1331. The snap ring 1341 is arranged around an axis parallel to the first direction X and penetrates the second clamping groove 114. When the driving member 134 moves along the second clamping groove 114, the arrangement of the snap ring 1341 can make the driving member 134 drive the light blocking plate 133 more stably.

[0046] In some embodiments, the driving member 134 may only have a driving rod, one end of which is connected to the base 110 and the other end is connected to the light blocking plate 133. The driving rod may be configured as a component that can undergo plastic deformation, and the user may bend the driving rod to directly drive the movement of the light blocking plate 133.

[0047] According to different driving requirements, the driving member 134 can also be configured as a threaded fastener 1343. Figure 5 As shown, in this embodiment, the driving member 134 is configured as a threaded fastener 1343, one end of the threaded fastener 1343 is connected to the base 110, and the other end is connected to the end of the light shielding plate 133 away from the light exit hole 1111, and the threaded fastener 1343 can be close to or away from the base 110 along the second direction Y. In other words, when the threaded fastener 1343 is screwed into the base 110, the light shielding plate 133 can be driven to move toward the side close to the light exit hole 1111, and when the threaded fastener 1343 is screwed out of the base 110, the light shielding plate 133 can be driven to move toward the side away from the light exit hole 1111. Specifically, the light shielding plate 133 can also be provided with a through hole engaged with the threaded fastener 1343, which is not limited here.

[0048] The light shielding plate 133 moves along the second direction Y. To further improve the stability of the movement of the light shielding plate 133, the base 110 may be provided with a limiter to further guide the movement of the light shielding plate 133. Figure 1 as well as Figure 2 As shown, in this embodiment, the base 110 has a shell 111 and a first stopper 115, the shell 111 defines a light exit hole 1111 and a first slot 113, the light shielding plate 133 defines a fourth slot 1332, the fourth slot 1332 extends along the second direction Y, one end of the first stopper 115 is connected to the shell 111, and the other end is clamped in the fourth slot 1332. Specifically, the first stopper 115 can be configured in any suitable form such as a bolt, a nut or a clamping block.

[0049] In mobile devices such as vehicles 200, in order to further improve the adaptability of the warning device 100 in vehicles 200 of different models, improve the parallelism between the boundary of the warning laser 121 of the warning device 100 and the driving direction of the vehicle 200, etc., the laser module 120 in the warning device 100 can be configured to be rotatable relative to the base 110, so that the angle of the warning laser 121 on the target surface can be more flexible. Figure 2 as well as Figure 4As shown, in this embodiment, the base 110 includes a shell 111 and a second stopper 116, the shell 111 defines a light exit hole 1111, a mounting hole 1112 and a stopper hole 1113, the mounting hole 1112 is connected to the light exit hole 1111, the stopper hole 1113 is connected to the mounting hole 1112, the laser module 120 is arranged in the mounting hole 1112, the laser module 120 can rotate relative to the base 110 around an axis parallel to the first direction X, so that the warning laser 121 can rotate around an axis parallel to the first direction X, and the second stopper 116 is arranged in the stopper hole 1113 and abuts against the laser module 120 to limit the rotation of the laser module 120. The second stopper 116 can also be configured as a nut or any other suitable component.

[0050] In order to further improve the convenience of installing the warning device 100 on a mobile device such as a vehicle 200, the warning device 100 may be provided with a connecting plate 117 for abutting against the wall panel of the vehicle 200. In order to further improve the warning range of the warning device 100, so that the warning device 100 can illustrate the travel route of a transportation device with a large width, or the warning laser 121 can be projected outside the actual boundary of the equipment's travel path to reduce the possibility of danger, the abutting surface 1171 of the connecting plate 117 can intersect with the first direction X, so that after the warning device 100 is installed, the warning laser 121 can be irradiated outside the actual movement boundary of the transportation device such as the vehicle 200. In other words, if Figure 7 as well as Figure 8 As shown, the warning boundary of the laser warning device 100 can be the boundary of the actual running track of the vehicle 200 or the like, or can be smaller or larger than the boundary of the actual running track of the vehicle 200 or the like. Figure 1 , Figure 5 as well as Figure 6 As shown, in this embodiment, the base 110 includes a shell 111 and a connecting plate 117, the shell 111 defines a light exit hole 1111, the connecting plate 117 is connected to the shell 111, and the connecting plate 117 defines an abutting surface 1171, and the abutting surface 1171 intersects with the projection surface 131.
