[0039] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0040] like Figure 1-Figure 5 As shown, the present invention provides an embodiment of a tablet stand specially used for field exploration, wherein the tablet stand comprises a first protective shell 1 and a second protective shell 2, wherein the first protective shell 1 is used to place a tablet computer 7, and the second protective shell 2 is used to place a keyboard; a moving mechanism is provided between the first protective shell 1 and the second protective shell 2; the moving mechanism is used to move the second protective shell 2 between the back side of the first protective shell 1 and the side of the display screen of the tablet computer 7 in the first protective shell 1.

[0041] When it is necessary to use a tablet to draw a vectorized cross-section of the oil field, the second protective shell 2 is flipped to the side of the display screen of the tablet computer 7 in the first protective shell 1, converting it into a notebook form for easy use.

[0042] When it is necessary to consult drawings and data related to the oil field, the second protective shell 2 is turned over to the back of the first protective shell 1 and the two are fixed to each other; the first protective shell 1 can be held to realize the handheld tablet computer 7.

[0043] In this embodiment, at least one set of supporting legs 4 is provided on the back of the first protective shell 1, and the supporting legs 4 are hinged to the first protective shell 1. When the tablet needs to be operated through the keyboard, the supporting legs 4 are opened, and the second protective shell 2 is placed horizontally on the support. The supporting legs 4 support the first protective shell 1, so that the angle between the tablet computer 7 and the keyboard is an obtuse angle, which is convenient for use; when holding the tablet computer 7, the supporting legs 4 can be made to fit the back of the first protective shell 1 and be relatively fixed.

[0044] To achieve the above functions, in this embodiment, a limit rod 5 is provided at the hinge of the support leg 4; the limit rod 5 is used to limit the support leg 4 from being away from the first protective shell 1. When the tablet computer 7 is held in hand, the limit rod 5 limits the support leg 4. When the tablet computer 7 needs to be supported, the limit rod 5 is released from the limit of the support leg 4.

[0045] At the same time, the limit rod 5 is also used to limit the relative movement between the second protective shell 2 and the first protective shell 1. When the tablet computer 7 is held in hand, the limit rod 5 limits the second protective shell 2 to the back of the first protective shell 1; when the keyboard needs to be operated, the limit rod 5 releases the restriction on the second protective shell 2, so that the second protective shell 2 can move, and the second protective shell 2 is flipped to the side of the display screen of the tablet computer 7 in the first protective shell 1, converting it into a notebook form.

[0046] The present application provides an embodiment of a moving mechanism, such as Figure 4 and Figure 6 As shown:

[0047] The moving mechanism includes a guide rail 21 and a slide 22; the guide rail 21 is vertically arranged on the back of the first protective shell 1, and the end of the guide rail 21 extends to the bottom of the first protective shell 1; the slide 22 is hinged to the top of the second protective shell 2; the slide 22 moves along the guide rail 21 or in a direction parallel to the guide rail 21; when the slide 22 is relatively located at the top of the guide rail 21, the second protective shell 2 is completely located on the back of the first protective shell 1, and when the slide 22 moves to the bottom of the guide rail 21, the hinge structure between the slide 22 and the second protective shell 2 enables the second protective shell 2 to be flipped toward the display screen side of the tablet computer 7 in the first protective shell 1, changing into the form of a laptop computer.

[0048] In this embodiment, the specific position of the second protective shell 2 is: the keyboard in the second protective shell 2 faces the back of the first protective shell 1, and when the second protective shell 2 is located on the back of the first protective shell 1, the keyboard is protected; and after the second protective shell 2 moves to the bottom of the first protective shell 1, it is directly flipped over and changed into the shape of a laptop computer.

[0049] In this embodiment, two groups of guide rails 21 are arranged in parallel, and the two groups of guide rails 21 are symmetrically provided with guide grooves 211 on the facing sides; at least one group of connecting rods 221 are respectively provided on both sides of the slide 22, and the ends of the connecting rods 221 are rotatably connected with guide wheels 222, the slide 22 is located between the two groups of guide rails 21, the guide wheels 222 are located inside the guide grooves 211, and the two are rollingly connected, so that the movement of the second protective shell 2 is smoother.

[0050] Further, such as Figure 4 As shown, in this embodiment, the moving mechanism also includes a fixed seat 23 and a screw rod 24; the fixed seat 23 is arranged on the back side of the first protective shell 1 and is located above the slide 22; the screw rod 24 is threadedly connected to the fixed seat 23, and the screw rod 24 is arranged vertically downward, and its end can contact the slide 22 along the axial direction; the screw rod 24 is used to drive the slide 22 to move vertically downward; when the keyboard needs to be operated, the screw rod 24 is rotated, and the end of the screw rod 24 applies downward pressure to the slide 22, so that the slide 22 moves downward.

[0051] Further, such as Figure 3 As shown, a connecting member 25 is provided on the back of the first protective shell 1, and a protrusion 26 is provided on the connecting member 25; the position of the protrusion 26 is set so that the second protective shell 2 is located between the first protective shell 1 and the protrusion 26; the position and structure of the connecting member 25 are set so as not to hinder the movement of the second protective shell 2.

[0052] To meet the above requirements, in this embodiment, two groups of connecting members 25 are provided, which are vertically arranged on the two side edges of the back side of the first protective shell 1. The structure of the connecting member 25 is an L-shaped bracket, whose short side is arranged perpendicular to the back side of the first protective shell 1, and whose long side is arranged parallel to the back side of the first protective shell 1. The protrusion 26 is arranged at the end of the long side of the L-shaped bracket. When the second protective shell 2 is completely located on the back side of the first protective shell 1, the end of the L-shaped bracket is located above the second protective shell 2.

[0053] A guide block 27 is provided on the back side of the second protective shell 2 along its own moving direction, which can contact the protrusion 26 during the movement; the surface where the guide block 27 contacts the protrusion 26 is an inclined surface, and the bottom of the inclined surface of the guide block 27 is inclined toward the second protective shell 2; as the second protective shell 2 moves, the protrusion 26 imposes restrictions on the inclined surface of the guide block 27, so that the bottom of the second protective shell 2 flips toward the side of the display screen of the tablet computer 7 in the protective shell.

[0054] The present application provides an embodiment of the hinge structure of the support leg 4, such as Figure 3 and Figure 7 Shown:

[0055] A hinge seat 41 is provided on the back of the first protective shell 1, and the support leg 4 is hinged to the hinge seat 41; the position and structure of the hinge seat 41 are set so as not to hinder the movement of the second protective shell 2; a deformable support member 42 is provided between the support leg 4 and the hinge seat 41; the support member 42 is used to limit the angle between the support leg 4 and the first protective shell 1.

[0056] In this embodiment, the hinge seat 41 and the connecting member 25 are the same structure (L-shaped bracket), which simplifies the structure. The long side of the L-shaped bracket is provided with a slot 46, and the support leg 4 can be received in the slot 46; two groups of support legs 4 are correspondingly arranged to increase the stability of the support for the first protective shell 1.

[0057] Further, such as Figure 8 As shown, in this embodiment, the support leg 4 is provided with a through groove 44 at its own axial position, and a slider 45 sliding along the through groove 44 is provided in the through groove 44; the two ends of the deformable support member 42 are respectively hinged to the slider 45 and the hinge seat 41; when the support leg 4 can be stored in the slot 46, one end of the deformable support member 42 slides along the slider 45 and will not be bent, thereby extending the service life.

[0058] In order to realize the limiting of the support leg 4 by the limiting rod 5, the present application provides an embodiment, such as Figure 3 , Figure 5 and Figure 7 As shown:

[0059] A positioning hole 43 is provided on one side of the support leg 4 close to the limiting rod 5, and one end of the limiting rod 5 can pass through the hinge seat 41 and be stuck in the positioning hole 43; a spring member 51 is provided between the hinge seat 41 and the limiting rod 5, and the spring member 51 is used to apply an external force to the limiting rod 5 to move toward the support leg 4.

[0060] Furthermore, the limiting rod 5 is arranged horizontally; a mounting plate 52 is vertically upwardly provided on one side of the limiting rod 5 away from the supporting leg 4; the spring member 51 is arranged parallel to the limiting rod 5, and both ends of the spring member 51 are respectively connected to the hinge seat 41 and the mounting plate 52.

[0061] Furthermore, the linkage rod 6 is arranged perpendicular to the back side of the second protective shell 2, and a block 61 is provided at the end of the linkage rod 6, and the moving trajectory of the block 61 can pass through the limiting rod 5; the limiting rod 5 is provided with a slot 53 that passes through the limiting rod 5 along the moving trajectory of the block 61; the positional relationship between the block 61 and the slot 53 is as follows: in the process of the block 61 passing through the slot 53, the block 61 contacts the side of the slot 53 away from the hinge seat 41, so that the block 61 applies an external force to the slot 53 of the limiting rod 5.

[0062] The surface where the block 61 contacts the notch 53 is an inclined surface, and the bottom of the inclined surface of the block 61 is inclined toward the hinge seat 41; when the block 61 passes through the notch 53, the bottom of the inclined surface of the block 61 first contacts the notch 53 of the limit rod 5, and as the block 61 moves downward, the position where the block 61 contacts the notch 53 becomes thicker, causing the entire limit rod 5 to be relatively displaced toward the side away from the hinge seat 41.

[0063] Therefore, when the block is moving downward, the inclined surface of the block 61 applies a squeezing force to the side of the notch 53 away from the hinge seat 41 , so that the end of the limiting rod 5 is disengaged from the positioning hole 43 of the supporting leg 4 .

[0064] When the thickest position of the block 61 contacts the notch 53 , the end of the limiting rod 5 can fall off from the hinge seat 41 .

[0065] Furthermore, in this embodiment, the pulling force applied by the spring member 51 to the limiting rod 5 is greater than the squeezing force applied by the block 61 to the limiting rod 5 under the gravity of the second protective shell 2 and the keyboard.

[0066] When the second protective shell 2 is located on the back of the first protective shell 1 , the limiting rod 5 limits the downward movement of the linkage rod 6 , thereby limiting the second protective shell 2 , thereby achieving relative fixation of the second protective shell 2 and the first protective shell 1 .

[0067] The above embodiments are only exemplary embodiments of the present application and are not intended to limit the present application. The protection scope of the present application is defined by the claims. Those skilled in the art may make various modifications or equivalent substitutions to the present application within the essence and protection scope of the present application, and such modifications or equivalent substitutions shall also be deemed to fall within the protection scope of the present application.
