In addition, the terms "first", "second", "third" are only for the purpose of description, and cannot be understood as indicating or implying relative importance. Physical quantities in the formula, such as no separate marking, should be understood as the basic quantity of the international system of units, or the derived quantity derived from the basic quantity by multiplication, division, differentiation or integration and other mathematical operations.

[0025] In the description of the utility model, it is necessary to explain that, unless there is definite stipulation and limitation, the terms "mount", "link", "connect" should be understood broadly, for example, it can be fixed connection, also can be detachable connection, or integrally connected, can be mechanical connection, also can be electrical connection, can be direct connection, also can through the intermediate medium indirectly connect, can be the intercommunication of two elements. For ordinary skilled in the art, the specific meaning of the above terms in the utility model can be understood according to the specific circumstances.

[0026] As Figure 1 And Figure 2 The utility model discloses a screen lock catch mechanism, including motor frame 100, motor 200, screw shaft 300, guide shaft 400 and lock catch piece 500, motor 200 and guide shaft 400 are installed respectively in motor frame 100, screw shaft 300 is transmission connection with motor 200, and screw shaft 300 is parallel with guide shaft 400, and lock catch piece 500 is slidably fitted in guide shaft 400, and lock catch piece 500 is screwed with screw shaft 300.

[0027] Motor 200 can drive screw shaft 300 to rotate, and lock catch piece 500 can be driven to reciprocate along guide shaft 400 by screw shaft 300, to realize locking action and unlocking action. Screw shaft 300 has self-locking function, and can ensure that lock catch piece 500 is stable under the condition of motor 200 power-off, so that the equipment operating power consumption is lower, and can adapt to the jolt condition, and the reliability of screen lock catch mechanism is improved.

[0028] In the utility model embodiment, lock catch piece 500 has lock hook 510, and lock hook 510 is provided with the pressing inclined surface 511 that is inclined upward from the end close to motor 200 to the end away from motor 200.

[0029] When screw shaft 300 drives lock catch piece 500 to lock screen 900, pressing inclined surface 511 abuts against screen 900, and gradually drives screen 900 to swing to horizontal posture, so that screen 900 and machine body 800 as a whole present the structure that tends to be plane.

[0030] As Figure 2 Screw shaft 300 is rotatably installed on motor frame 100 through bearing 600, and is lubricated through bearing 600, so as to reduce the rotation resistance of screw shaft 300.

[0031] As Figure 1As shown, in an optional embodiment, the motor frame 100 is mounted with a position sensor 700, which is used to detect the position of the locking member 500. The position sensor 700 may include a photoelectric sensor, an electromagnetic sensor, or an ultrasonic sensor. The position sensor 700 detects the distance between itself and a specific part of the locking member 500, thereby determining the working position of the locking member 500.

[0032] like Figure 1 and Figure 2 As shown, the locking member 500 is provided with a first sensing portion and a second sensing portion. The first sensing portion and the second sensing portion correspond to the position sensor 700 respectively and are spaced apart along the extending direction of the guide shaft 400 .

[0033] When controlling the motor 200, when the position sensor 700 is triggered by the first sensing part, the locking member 500 moves to one end of the stroke. At this time, the motor 200 is controlled to reverse, and the locking member 500 moves to the other end of the stroke until the position sensor 700 is triggered by the second sensing part, and the motor 200 is controlled to reverse again, so that the reciprocating movement control of the locking member 500 can be realized.

[0034] like Figure 2 As shown, the motor frame 100 has a first limiting end plate 101 and a second limiting end plate 102, which are spaced apart along the guide shaft 400, and the locking member 500 is located between the first limiting end plate 101 and the second limiting end plate 102. The screw shaft 300 and the guide shaft 400 both extend from the first limiting end plate 101 to the second limiting end plate 102, and the travel of the locking member 500 is limited between the first limiting end plate 101 and the second limiting end plate 102, resulting in a more compact structure.

[0035] In an optional embodiment, the locking member 500 is configured as an integrally molded plastic member. The plastic member itself has a certain shock-absorbing effect, which can prevent the screen 900 from being damaged by rigid extrusion.

[0036] like Figure 1 As shown, the ceiling screen assembly provided by an embodiment of the present invention includes: a body 800, a screen 900 and the screen locking mechanism described in the above embodiment; the screen 900 is pivotally connected to the body 800, the motor frame 100 is installed on the body 800, and the locking member 500 is used to lock the screen 900.

[0037] In an embodiment of the present invention, the screen 900 is provided with a slot 901 adapted to the locking member 500, and the locking hook 510 can be matched with the slot 901, thereby locking the screen 900 in a closed state, ensuring that the screen 900 is firmly locked in bumpy working conditions and when the screen 900 is not in use.

[0038] The vehicle provided by the embodiment of the present invention is equipped with the ceiling screen assembly described in the above-mentioned embodiment. The vehicle has the technical effects of the above-mentioned ceiling screen assembly, which will not be described in detail here.

[0039] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the above embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the scope of the technical solutions of the embodiments of the present invention.
