[0031] In order to make the purpose, features and advantages of the utility model more obvious and easy to understand, the technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of them. Based on the embodiments of the utility model, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the utility model.

[0032] An embodiment of the utility model provides a fixed connection structure, including a male end component and a female end component, which are plug-in connected to each other, wherein a locking groove can be set on the male end component, and a locking protrusion can be set on the female end component. When the male end component and the female end component are plugged into the set position, the locking protrusion and the locking groove are snap-fitted, thereby realizing a stable connection between the male end component and the female end component.

[0033] The following describes the components in the fixed connection structure provided by the embodiment of the utility model, and the connection relationship and position relationship between the components in conjunction with the accompanying drawings.

[0034] like Figures 1 to 4 As shown, in the embodiment of the utility model, the male end component 10 includes a plug-in portion 11, and the outer wall of the plug-in portion 11 is provided with a locking groove 12, for example, the locking groove 12 is arranged at one end close to the plug-in portion 11, and a mounting portion 14 is arranged at the other end of the plug-in portion 11, and the mounting portion 14 is connected to the plug-in portion 11, and the plug-in portion 11 is installed on the structure connected to the male end component 10 through the mounting portion 14, for example, the plug-in portion 11 is connected to the system end 1 or the display end 2 of the electronic product, for example, a mounting hole 33 is arranged on the mounting portion 14, and a mounting hole 33 is arranged on the shell of the corresponding system end 1 or the display end 2, and the mounting holes 33 on the two structures are arranged relative to each other and are fastened by mounting screws.

[0035] The female end assembly 20 includes a base 21, on which a plug hole 22 is provided, and one end of the plug hole 22 is provided with two locking plates 23 extending along the plug direction, the two locking plates 23 are arranged in parallel and at intervals, and the two locking plates 23 can be used to generate elastic deformation, and a locking protrusion 24 is provided on the inner wall of the locking plate 23. The plug direction can be interpreted as: the direction in which the plug part 11 slides in the plug hole 22 after entering the plug hole 22. The locking plate 23 is located at one end of the plug hole 22, and the locking protrusion 24 is arranged on the locking plate 23, which is equivalent to the locking protrusion 24 being located at one end of the female end assembly 20. The female end assembly 20 is connected to the structure connected to the female end assembly 20 through the base 21. For example, the base 21 is provided with a mounting hole 33, and the corresponding system end 1 or display end 2 is provided with a mounting hole. The mounting holes on the two structures are arranged relative to each other and are fastened by mounting screws.

[0036] When the male end component 10 is connected to the female end component 20, the plug-in part 11 is plugged into the space between the plug-in hole 22 and the locking plate 23, wherein the outer wall of the plug-in part 11 fits against the inner wall of the plug-in hole 22, and the spacing between the two locking protrusions 24 is slightly smaller than the outer diameter of the plug-in part 11. After the plug-in part 11 is inserted into the gap between the locking plates 23, the locking plates 23 are gradually deformed outward under the extrusion of the locking protrusions 24. The thickness of the locking plate 23 (thin-wall structure) meets the deformation requirements. With the plug-in operation, when the locking protrusion 24 slides into the locking groove 12, the locking plate 23 is reset to achieve the snap connection between the locking groove 12 and the locking protrusion 24.

[0037] Correspondingly, when the male end component 10 and the female end component 20 are separated, the clamping force of the locking plate 23 on the locking protrusion 24 (plug-in part 11) is overcome by external force, so that the locking protrusion 24 and the locking groove 12 are separated, and then the plug-in part 11 can be pulled out from the locking plate 23 and the plug-in hole 22 bracket.

[0038] For example, the locking plate 23 and the base 21 are integrally formed structures, and the thickness of the locking plate 23 meets the requirements of deformation and automatic reset. The integrally formed structure ensures good connection strength between the locking plate 23 and the base 21 and is easy to manufacture.

[0039] For example, the plug-in portion 11 includes a front side and a back side, and locking grooves 12 are respectively provided on the front side and the back side of the plug-in portion 11; locking protrusions 24 are respectively provided on the inner walls of the two locking plates 23; when the male end assembly 10 is connected to the female end assembly 20, the two locking grooves 12 are respectively engaged with the locking protrusions 24 on the same side. When the male end assembly 10 and the female end assembly 20 are connected, the front side and the back side of the plug-in portion 11 are engaged with the female end assembly 20, which can further improve the connection strength of the male end assembly 10 and the female end assembly 20 and the stability of the connection between the two.

[0040] In the embodiment of the utility model, the number of faces of the plug-in portion 11 is not limited, and it may also be three faces, four faces or more faces, and the developed plug-in hole 22 is set to have the same structural shape as it.

[0041] Continue to refer Figures 1 to 4 As shown, in the embodiment of the utility model, the outer wall of the plug-in portion 11 fits with the inner walls of the plug-in hole 22 and the locking plate 23, and by providing guide surfaces on the plug-in portion 11, the plug-in hole 22 and the locking plate 23, the male end component 10 and the female end component 20 can be provided with an auxiliary guiding function during the plug-in process, that is, adaptive positioning can be achieved during the plug-in process, thereby facilitating the user's alignment; and after the plug-in operation is completed, the guide surfaces on the male end component 10 and the female end component 20 fit together, which can play a further limiting role, thereby improving the stability of the connection.

[0042] For example, the front and / or back of the plug-in portion 11 is provided with a first guide surface 13; the inner walls of the plug-in hole 22 and the locking plate 23 are provided with a second guide surface 25 having the same angle as the first guide surface 13; when the male end assembly 10 is connected to the female end assembly 20, the first guide surface 13 and the second guide surface 25 are in contact. For example, the first guide surface 13 and the second guide surface 25 include multiple surfaces along the plug-in direction, so that a multi-stage structure is formed on the first guide surface 13 and the second guide surface 25.

[0043] Through the multi-section structure, an auxiliary guiding function can be achieved during the plug-in process of the male end component 10 and the female end component 20, and after the plug-in is completed, the multi-section guide surfaces fit tightly together to limit each other, thereby reducing the probability or amplitude of shaking between the male end component 10 and the female end component 20.

[0044] For example, the first guide surface 13 and the second guide surface 25 include a plurality of wedge-shaped surfaces 31 and a plurality of straight surfaces 32 along the plugging direction; at least one wedge-shaped surface 31 is arranged between two adjacent straight surfaces 32, and along the plugging direction, the linear distance between the wedge-shaped surface 31 and the center line of the plug-in portion 11 gradually decreases; the locking protrusion 24 and the locking groove 12 are arranged on the straight surface 32. Figures 1 to 4 As shown, in the structure shown in the figure, the plug-in portion 11 includes two wedge-shaped surfaces 31 and three straight surfaces 32. For example, the number of the wedge-shaped surfaces 31 and the straight surfaces 32 can be selected according to the length of the plug-in portion 11 and the depth of the plug-in hole 22.

[0045] In the embodiment of the utility model, the outer wall at the end of the plug-in part 11 and the inner wall of the locking plate 23 are straight surfaces 32. During the plug-in process of the male end component 10 and the female end component 20, except for the straight surface 32 at the end, the other parts of the plug-in part 11 are guide structures, and the corresponding plug-in holes 22 are all guide structures. After the plug-in operation is completed, the two are completely fitted, and there is no space for relative shaking or the gap that can cause shaking is very small, thereby ensuring the stability of the connection between the male end component 10 and the female end component 20.

[0046] The utility model also provides an electronic product, including the above-mentioned fixed connection structure. Figure 5 As shown, the electronic product includes a display terminal 2 and a system terminal 1; the male terminal component 10 of the fixed connection structure is connected to the system terminal 1, and the female terminal component 20 of the fixed connection structure is connected to the display terminal 2. For example, the electronic product is a two-in-one tablet computer, that is, the system terminal 1 and the display terminal 2 are two independent structures. Among them, one use form is a "tablet computer" form. At this time, only the display terminal 2 part can be used. Since the plug-in portion 11 will protrude from the shell of the male terminal component 10 (for plugging with the plug hole 22) when the male terminal component 10 is connected, the male terminal component 10 can be set at the system terminal 1 to reduce the impact on the use of the user. The two-in-one tablet computer realizes different use functions through different combination states. When it is necessary to realize the "laptop computer" form, it is necessary to connect the system terminal 1 and the display terminal 2, and the connection between the system terminal 1 and the display terminal 2 is realized through the male terminal component 10 and the female terminal component 20.

[0047] In the embodiment of the utility model, the display terminal 2 further includes a rotating shaft 26, one rotating part of the rotating shaft 26 is fixedly connected to the display terminal 2, and the other rotating part is connected to the base 21 of the female end component 20. When the male end component 10 and the female end component 20 are connected, the male end component 10 can position the female end component 20, that is, when the display terminal 2 is rotated, the part of the rotating shaft 26 connected to the base 21 is fixed, and the rotating part connected to the display terminal 2 rotates synchronously with the display terminal 2, that is, the connection between the display terminal 2 and the system terminal 1 is realized, and the relative opening and closing angles of the display terminal 2 and the system terminal 1 can also be adjusted.

[0048] The utility model provides a fixed connection structure and an electronic product. When the male end component 10 and the female end component 20 are connected, the plug-in portion 11 is inserted into the plug-in hole 22 along the plug-in direction and inserted into the plug-in hole 22 for a distance. With the continuous plug-in operation, the locking protrusion 24 squeezes the locking plate 23, causing the two locking plates 23 to deform outward. When the locking protrusion 24 slides into the locking groove 12, the locking plate 23 is reset, thereby completing the clamping of the locking groove 12 and the locking protrusion 24. In the technical solution of the utility model, the end of the plug-in portion 11 is connected to the locking plate 23 by a clamping method, without a spring structure, and the space required to complete the clamping operation is smaller, which is conducive to the lightweight design of the product, and the connection strength between the two is reliable, avoiding / reducing the problems of shaking and falling off when the screen is opened. At the same time, after removing the spring and the spring locking screws and other structures, the cost can be further reduced.
