[0016] In order to make the above-mentioned purposes, features and advantages of the utility model more obvious and easy to understand, the specific implementation methods of the utility model are described in detail below in conjunction with the accompanying drawings. In the following description, many specific details are set forth to facilitate a full understanding of the utility model. However, the utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without violating the connotation of the utility model, so the utility model is not limited by the specific embodiments disclosed below.

[0017] In the description of the embodiments of the present utility model, it should be noted that, unless otherwise clearly specified and limited, the terms, "connection" and "installation" should be understood in a broad sense. For example, "connection" can be a detachable connection or a non-detachable connection; it can be a direct connection or an indirect connection through an intermediate medium. In addition, "connection" can be a direct connection or an indirect connection through an intermediate medium. Among them, "fixed" means that they are connected to each other and the relative position relationship after connection remains unchanged. The directional terms mentioned in the embodiments of the present utility model, such as "inside", "outside", "top", "bottom", etc., are only reference to the directions of the accompanying drawings. Therefore, the directional terms used are for better and clearer explanation and understanding of the embodiments of the present utility model, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the embodiments of the present utility model.

[0018] In the embodiments of the present invention, the terms "first" and "second" are used for descriptive purposes only and cannot be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features.

The terms "including", "comprising", "having" and their variations all mean "including but not limited to", unless otherwise specifically emphasized in other ways. Therefore, the utility model is not limited to the specific embodiments disclosed below.

[0021] like Figure 1-Figure 4 As shown, the utility model provides a stepless inclination adjustment and positioning structure for digital equipment, characterized in that it includes: an upper shell 10 and a lower shell 11; one side of the upper shell 10 is hinged to the lower shell 11, a plurality of key caps are provided on the upper shell 10, and the lower shell 11 is provided with at least one height adjustment device 12, and the height adjustment device 12 is also movably connected to the upper shell 10, and the height adjustment device 12 uses a screw rod to control the adjustment of the inclination of the upper shell 10.

[0022] Specifically, the upper shell 10 is a relatively closed structure, and the keycaps and the substrate are both placed in the upper shell 10. One side of the upper shell 10 is hinged to the lower shell 11, and the upper shell 10 can rotate vertically relative to the lower shell 11 around the hinge. At the same time, a height adjustment device 12 for making the upper shell 10 in an inclined state is also provided on the lower shell 11. The number of the height adjustment devices 12 can be increased according to the setting position. For example, if it is set on the side of the lower shell 11 away from the hinge with the upper shell 10, one can be set; if it is set at both ends of the lower shell 11, two can be set. The high height adjustment device 12 uses the principle of screw rod lifting to control the height and positioning of the upper shell 10, and because a screw rod is used, it can achieve stepless adjustment, that is, it can hover at any height within a predetermined range.

[0023] Further, the height adjustment device 12 includes: a screw rod 13; the screw rod 13 is fixed to the lower shell 11 through two connecting seats 15, a screw rod nut 16 is provided on the screw rod 13, and the screw rod nut is connected to a push rod 17, and one end of the push rod 17 away from the screw rod nut 16 is connected to the upper shell 10, and one end of the screw rod 13 is also connected to a rotating knob 18;

[0024] Specifically, the screw rod 13 is fixed on the lower shell 11 through two spaced connection seats 15, and a screw nut 16 is connected to the screw rod 13. The screw nut 16 moves along the screw rod when the screw rod 13 rotates. A push rod 17 is rotatably connected to the screw nut 16. The other end of the push rod 17 is movably connected to the upper shell 10. When the screw nut 16 moves, it pushes the push rod 17. Since the push rod 17 cannot move relative to the screw nut 16 and the upper shell 10, when it is pushed by the screw nut 16, Lift up the upper shell 10 to rotate it relative to the lower shell 11, wherein a rotating knob 18 is connected to one end of the screw rod 13, and the rotating knob 18 is used to drive the rotation of the screw rod 13, so that the inclination of the upper shell 10 is controlled by rotating the knob 18 to achieve stepless adjustment; it can adapt to hand movements to the greatest extent and avoid fatigue and soreness caused by inappropriate angles. Moreover, due to the use of the screw rod structure, it has its own self-limiting effect and can be fixed at any position without sliding easily, and it is smooth and stable to use.

[0025] It should be pointed out that the screw rod 13 can be one or two. When the height adjustment device 12 is arranged on one side of the lower shell 11, two screw rods 13 are preferably arranged, and each screw rod 13 is respectively provided with a screw nut 16, and the screw nut 16 is connected to a push rod 17. At the same time, the rotation directions of the two screw rods 13 are opposite, so that the two push rods 17 move in opposite directions when moving, so that the two are trapezoidal in shape to achieve stable support; when the height adjustment device 12 is arranged at both ends of the lower shell 11, since the upper shell 10 is supported from both ends, at this time, even if the number of screw rods of each height adjustment device 12 is one, there will be no left and right tilting.

[0026] Furthermore, in this embodiment, the screw nut 16 is located between the two connecting seats 15;

[0027] Specifically, in order to facilitate the control of the movement stroke and lifting height of the screw nut 16, the screw nut 16 is located in the two connecting seats 15 of the screw 13. When the screw nut 16 moves to the limit distance, it will resist the connecting seat 15 on the corresponding side. Restricted by the connecting seat 15, the minimum height and maximum height are achieved. The preferred minimum height should avoid the push rod 17 being in a horizontal state to avoid excessive resistance and inability to lift the upper shell 10. At the maximum height, the push rod 17 should be in a vertical state to avoid excessive movement and the resulting decrease in the tilt height of the upper shell 10.

[0028] Furthermore, in this embodiment, the push rod 17 and the upper shell 10 are connected by a ball head;

[0029] Specifically, since the side of the upper shell 10 does not move in a straight line when it is tilted, but moves along an arc, this will cause an angle change between the push rod 17 and the side of the upper shell 10. In order to avoid smooth movement between the two, the push rod 17 and the upper shell 10 are preferably connected by a ball head to avoid this situation. The ball head can cause a certain angle change between the upper shell 10 and the push rod 17 without affecting the movement between the two.

[0030] To sum up, the present application realizes stepless adjustment and fixation of the upper shell 10 by setting a height adjustment device 12 between the upper shell 10 and the lower shell 11, and the height adjustment device 12 adopts a screw lifting structure, so that the upper shell 10 can be adjusted arbitrarily at a height within a range, which is more practical. The total height of this structure can be determined according to needs. It is simple to use and can be electrically controlled when necessary, which has a stronger sense of technology.

[0031] The present invention is not limited to what is described in the specification and implementation modes, and therefore, additional advantages and modifications can be easily realized by those familiar with the art. Therefore, without departing from the spirit and scope of the general concept defined by the claims and their equivalents, the present invention is not limited to the specific details, representative devices, and illustrative examples shown and described herein.
