Description

Technical Field

[0001] This application relates to the technical field of desktop terminal accessories, and particularly to a rotating mechanism and an electronic terminal. Background Art

[0002] Many existing electronic products are provided with rotatable and foldable structures to add the function of convenient storage while maintaining the original usage functions. For example, in some existing scanning pen structures, it includes a main body and a scanning component. There is a storage slot on the main body that can accommodate the scanning component. The scanning component is rotatably connected to the main body through a rotating shaft. When the scanning function is needed, only the scanning component needs to be rotated and unfolded. After use, the scanning component can be rotated and stored in the storage slot. At this time, the overall size of the entire scanning pen is greatly reduced, making it more convenient for storage. In the specific structure of the existing scanning pen, the scanning component is rotatably connected to the rotating shaft. There are limiting holes provided on the housing of the main body. The end of the rotating shaft is inserted into the limiting holes for fixation, so that the scanning component can rotate and open and close relative to the main body around the rotating shaft. Generally, in order to maintain the stability of the structure after unfolding, a damping or elastic retaining member is provided in the rotatable connection structure between the scanning component and the rotating shaft, so that the scanning component can remain relatively fixed to the main body after the user releases the hand. In addition, to save costs and reduce weight, the housing of the main body is generally made of plastic. Under the action of the damping or elastic retaining member, when rotating the scanning component, the rotating shaft needs to bear a large torsional force, and this torsional force ultimately acts on the limiting holes of the main body housing. Since the plastic main body housing has poor durability, after rotating the scanning component multiple times, the limiting holes on the main body housing will be deformed and expanded under the action of the torsional force of the rotating shaft, and then the gap between the rotating shaft and the wall surface of the limiting hole will gradually increase, resulting in looseness between the rotating shaft and the main body. Therefore, there are technical problems in the rotatable connection structure of the existing scanning pen: the product service life is short, affecting the user experience.

[0031] To make the technical problems solved by this application, the technical solutions adopted and the achieved technical effects clearer, the technical solutions of the embodiments of this application will be further described in detail below. Obviously, the described embodiments are only a part of the embodiments of this application, rather than all the embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative efforts shall fall within the scope of protection of this application.

[0032] In the description of this application, unless otherwise clearly specified and limited, the terms "connected", "connected", and "fixed" shall be understood in a broad sense. For example, it may be a fixed connection, a detachable connection, or integrated; it may be a mechanical connection or an electrical connection; it may be directly connected or indirectly connected through an intermediate medium, and it may be the internal connection or the interaction relationship between two components. For those of ordinary skill in the art, the specific meanings of the above terms in this utility model can be understood according to specific situations.

[0033] In this application, unless otherwise clearly specified and limited, the first feature being "above" or "below" the second feature may include the direct contact between the first and second features, or may include the situation where the first and second features are not in direct contact but in contact through other features between them. Moreover, the first feature being "above", "above", and "on the top" of the second feature includes the first feature being directly above and obliquely above the second feature, or merely indicating that the first feature has a higher horizontal height than the second feature. The first feature being "below", "below", and "under the bottom" of the second feature includes the first feature being directly below and obliquely below the second feature, or merely indicating that the first feature has a lower horizontal height than the second feature.

[0034] There are many existing electronic products that are provided with rotatable and foldable structures to add the function of convenient storage on the basis of maintaining the original usage functions. For example, in some existing scanning pen structures, it includes a main body and a scanning component. There is a storage groove on the main body that can accommodate the scanning component. The scanning component is rotatably connected to the main body through a rotating shaft. When the scanning function is needed, only the scanning component needs to be rotated and unfolded. After use, the scanning component can be rotated and stored in the storage groove. At this time, the overall size of the entire scanning pen is greatly reduced, making it more convenient for storage. In the specific structure of the existing scanning pen, the scanning component is rotatably connected to the rotating shaft. There are limiting holes provided on the housing of the main body, and the end of the rotating shaft is inserted into the limiting holes for fixation, so that the scanning component can rotate and open and close relative to the main body around the rotating shaft. Generally, in order to maintain the stability of the structure after unfolding, a damping or elastic retaining member is provided in the rotating connection structure between the scanning component and the rotating shaft, so that the scanning component can remain relatively fixed to the main body after the user releases the hand. In addition, to save costs and reduce weight, the housing of the main body is generally made of plastic. Under the action of the damping or elastic retaining member, when rotating the scanning component, the rotating shaft needs to bear a large torsional force, and this torsional force finally acts on the limiting holes of the main body housing. Since the plastic main body housing has poor durability, after rotating the scanning component multiple times, the limiting holes on the main body housing will be deformed and expanded under the action of the torsional force of the rotating shaft, and then the gap between the rotating shaft and the wall surface of the limiting hole will gradually increase, resulting in looseness between the rotating shaft and the main body. Therefore, the existing rotating connection structure of the scanning pen has technical problems: the product service life is short, which affects the user experience.

[0035] In order to overcome the above technical problems, referring to Figures 1-8 , this embodiment provides a rotating mechanism, including a rotating shaft 3, a first bracket 1 and a second bracket 2. The rotating shaft 3 is rotatably connected to the first bracket 1 and fixedly connected to the second bracket 2. Thus, based on the relative rotation of the first bracket 1 and the rotating shaft 3, the relative rotation of the first bracket 1 and the second bracket 2 can be realized. The rotating mechanism of this embodiment can be applied to various desktop terminals or electronic terminals, such as a flip-type smart watch, a smart phone, a laptop computer, a scanning pen and other electronic terminals, or a desktop mobile phone stand, etc. Taking the application in a scanning pen as an example, the first bracket 1 serves as the housing of the scanning component, and the second bracket 2 serves as the housing of the main body. By rotating the first bracket 1, its unfolding or recycling can be realized.

[0036] Regarding the structure of the fixed connection between the rotating shaft 3 and the second bracket 2, the second bracket 2 is provided with a limiting hole 21, and the end of the rotating shaft 3 is provided with a plug-in portion 31. The plug-in portion 31 is plugged into the limiting hole 21 to realize the connection of the rotating shaft 3 to the second bracket 2. At least one side of the second bracket 2 is provided with a side fixing hole 22 communicating with the limiting hole 21, and a preloading member 4 is installed in the side fixing hole 22, and the preloading member 4 presses the rotating shaft 3.

[0037] Among them, the shape of the insertion part 31 is adapted to that of the limiting hole 21. After the insertion part 31 is inserted into the limiting hole 21, the limiting hole 21 can completely lock the insertion part 31, so that the insertion part 31 cannot rotate relative to the second bracket 2.

[0038] Based on the rotating mechanism of this embodiment, a limiting hole 21 is provided on the second bracket 2, and an insertion part 31 is provided at the end of the rotating shaft 3. The insertion part 31 is inserted into the limiting hole 21 for fixation; further, at least one side fixing hole 22 communicating with the limiting hole 21 is provided on the second bracket 2, and a preloading member 4 is installed in the side fixing hole 22. The preloading member 4 rigidly presses the rotating shaft 3. With such a setting, the contact area between the insertion part 31 and the side wall of the limiting hole 21 can be effectively reduced, and further the degree of deformation and expansion of the material on the side wall of the limiting hole 21 under the action of the torsional force of the insertion part 31 can be reduced, so that the connection between the second bracket 2 and the rotating shaft 3 can still maintain a stable connection after undergoing more rotation and opening / closing operations, thus achieving the effect of extending the service life of the rotating mechanism and optimizing the user experience of the product.

[0039] During specific implementation, one or more side fixing holes 22 can be provided, and one preloading member 4 is provided in each side fixing hole 22. The preloading member 4 rigidly presses the rotating shaft 3. On one side or multiple sides of the limiting hole 21 where the preloading member 4 is provided, after the rotating shaft 3 is installed, the preloading member 4 directly contacts the rotating shaft 3 and bears the torsional force applied by the rotating shaft 3, so that the deformation of the material on the side of the limiting hole 21 where the preloading member 4 is located can be effectively avoided. It can be understood that the more the number of the provided preloading members 4, the better the durability of the rotating structure.

[0040] The side fixing hole 22 can be a through hole or a blind hole. When the side fixing hole 22 is set as a through hole, the preloading member 4 can be directly inserted from the outer wall side of the second bracket 2; when the side fixing hole 22 is a blind hole, the preloading member 4 can only be inserted from the opening of the limiting hole 21.

[0041] According to requirements, one or more rotating shafts 3 can be provided in the connection structure between the first bracket 1 and the second bracket 2. When multiple rotating shafts 3 are provided, it is necessary to ensure that the rotation centers of the multiple rotating shafts 3 are coaxial. When one rotating shaft 3 is provided, the insertion part 31 can be provided only at one end of the rotating shaft 3, or the insertion parts 31 can be respectively provided at both ends of the rotating shaft 3. Providing two insertion parts 31 to provide two-point support can effectively improve the reliability of the rotating connection structure between the first bracket 1 and the second bracket 2. When only one rotating shaft 3 is provided and the insertion part 31 is provided only at one end thereof, the length of the rotating shaft 3 can be effectively shortened, the consumption of the rotating shaft 3 can be reduced, and the cost can be lowered. Preferably, for improving stability, referring to Figure 3 a rotating cylinder 6 spaced from and coaxial with the rotating shaft 3 is fixedly provided on the first bracket 1, and the rotating cylinder 6 is rotatably connected to the second bracket 2, so as to provide two-point support and achieve the effect of improving the reliability of the structure.

[0042] In one embodiment, the preloading member 4 is a rigid structure.

[0043] The preloading member 4 being of a rigid structure has the advantage of strong anti-deformation ability and can provide a strong pressing force to press the rotating shaft 3, while avoiding the problem of deformation of the preloading member 4 due to extrusion by the rotating shaft 3 after long-term use.

[0044] Preferably, the preloading member 4 is made of a material with good rigidity, such as metal materials like steel and aluminum, or carbon fiber, fiberglass, etc.

[0045] In one embodiment, the side fixing hole 22 is provided with an internal thread, the preloading member 4 is provided with an external thread, and the preloading member 4 is threadedly installed in the side fixing hole 22.

[0046] Threaded connection can provide a high pre-tightening force and friction force, thus ensuring that the preloading member 4 will not loosen after installation and effectively maintaining the stable connection between the rotating shaft 3 and the second bracket 2. Additionally, by rotating the preloading member 4, the pressing degree of the preloading member 4 against the rotating shaft 3 can be conveniently adjusted. This adjustability enables fine-tuning according to actual needs during the assembly process to achieve the best connection effect.

[0047] For the convenience of installing the preloading member 4, the side fixing hole 22 is preferably a through hole, allowing the preloading member 4 to be threadedly screwed into the side fixing hole 22 from the outer bracket of the second bracket 2.

[0048] In one embodiment, the side surface of the insertion portion 31 in contact with the preloading member 4 is a flat surface.

[0049] The side surface of the insertion portion 31 in contact with the preloading member 4 is a flat surface. The flat surface contact increases the contact area between the preloading member 4 and the insertion portion 31, thereby improving the connection stability. During rotation, even when subjected to a large torsional force, the large contact surface can be used to disperse and bear these forces to maintain the tightness of the connection.

[0050] In one embodiment, in combination Figure 4 and Figure 6 , the second bracket 2 is further provided with a limiting boss 23 located in the limiting hole 21. The insertion portion 31 is provided with a limiting groove 311 adapted to the limiting boss 23. The limiting boss 23 is fitted into the limiting groove 311, and the relative rotation of the rotating shaft 3 and the second bracket 2 is further restricted by the cooperation of the limiting boss 23 and the limiting groove 311.

[0051] A limiting boss 23 is additionally provided in the second bracket 2, and a limiting groove 311 is correspondingly provided at the end of the insertion part 31. When installed, the limiting boss 23 just snaps into the limiting groove 311. In this way, the limiting contact area between the insertion part 31 and the second bracket 2 can be increased, the connection reliability can be further improved, and at the same time, the material of the second bracket 2 that bears the torsional force applied by the insertion part 31 is increased, the stress on the material around the limiting hole 21 is reduced, and the degree of deformation and expansion of the side wall material of the limiting hole 21 under the action of the torsional force of the insertion part 31 is further reduced, thereby improving the durability of the rotating mechanism.

[0052] Optionally, the limiting boss is used to further limit the rotation of the insertion part, and its structure can be a non-rotary body, and it can be, but not limited to, structures such as D-shaped, C-shaped, E-shaped, etc. that increase the limiting contact positions for preventing rotation.

[0053] In one embodiment, referring to Figure 6 , the radial section of the insertion part 31 is "D"-shaped, and the limiting hole 21 is a corresponding "D"-shaped hole.

[0054] Due to the asymmetry of the "D" shape, the insertion part 31 cannot rotate freely after being inserted into the limiting hole 21. This design can ensure that the rotating shaft 3 remains fixed at a specific angle or direction, avoiding unnecessary rotation and loosening, and improving the connection stability and reliability. Compared with a circular or other symmetric shape, the shape feature of the "D" shape is more obvious, which helps to achieve more accurate positioning during the assembly process, which can reduce the assembly error and ensure the correct alignment and tight fit between the rotating shaft 3 and the second bracket 2.

[0055] In one embodiment, the second bracket 2 includes a bracket main body and a bracket bottom cover covering one side of the bracket main body. The limiting hole 21 is provided on the bracket main body, and the side fixing hole 22 is only provided on one side of the limiting hole 21 close to the bracket bottom cover. The bracket bottom cover covers the side fixing hole 22 and the preloading member 4.

[0056] As Figure 5 shown, only the structure of the bracket main body is shown in this figure, and the bracket bottom cover is not shown. The bottom side of the bracket main body in the figure is the side for installing the bracket bottom cover. The bracket main body, as the main load-bearing component, is provided with a limiting hole 21 for the insertion and positioning of the insertion part 31, and the side fixing hole 22 is provided on one side of the limiting hole 21 close to the bracket bottom cover. This design can ensure that the preloading member 4 firmly presses against the insertion part 31 during installation, thereby preventing the rotating shaft 3 from loosening or shifting during rotation. At the same time, after installing the bracket bottom cover, it covers the side fixing hole 22 and internal components such as the preloading member 4, making the appearance of the entire second bracket 2 more neat and beautiful. This design is particularly suitable for products with high appearance requirements, such as electronic products and precision instruments.

[0057] In one embodiment, referring to Figure 6 , a locking assembly 5 is further provided on the rotating shaft 3. The locking assembly 5 includes a rotating wheel 51, a locking wheel 52 and an elastic member 53 that are respectively sleeved on the rotating shaft 3. The rotating wheel 51 can rotate relative to the rotating shaft 3, and the first bracket 1 is fixedly connected to the rotating wheel 51; the locking wheel 52 can axially move relative to the rotating shaft 3, and its rotational freedom is locked; on one side of the rotating wheel 51 facing the locking wheel 52, there are engaging teeth 511, and on one side of the locking wheel 52 facing the rotating wheel 51, at least two card slots 521 are provided. The elastic member 53 pushes the locking wheel 52 towards the rotating wheel 51 to make the engaging teeth 511 engage with the card slots 521, so as to lock the relative rotation of the first bracket 1 and the second bracket 2.

[0058] Specifically, the rotating wheel 51 is sleeved on the rotating shaft 3 and fixedly connected to the first bracket 1. When the user needs to rotate the first bracket 1, in fact, the rotating wheel 51 is driven to rotate around the rotating shaft 3. On one side of the rotating wheel 51 facing the locking wheel 52, there are engaging teeth 511, and these engaging teeth 511 are used to engage with the card slots 521 on the locking wheel 52, so as to achieve the locking function. The locking wheel 52 is also sleeved on the rotating shaft 3, but different from the rotating wheel 51, its rotational freedom is locked, that is, it cannot rotate around the rotating shaft 3. However, the locking wheel 52 can axially move relative to the rotating shaft 3. On one side of the locking wheel 52 facing the rotating wheel 51, at least two card slots 521 are provided, and the positions and numbers of these card slots 521 determine the different opening and closing angles at which the first bracket 1 can be locked. The elastic member 53 (such as a spring) is installed between the locking wheel 52 and the rotating shaft 3 and is used to push the locking wheel 52 towards the rotating wheel 51. In the absence of external force, the locking wheel 52 will maintain a state of being in close contact with the rotating wheel 51, so that the engaging teeth 511 can smoothly engage with the card slots 521; when the user needs to adjust the angle of the first bracket 1, just rotate the first bracket 1 forcefully to make the locking wheel 52 move backward against the thrust of the elastic member 53. At this time, the engaging teeth 511 will disengage from the current card slot 521 and slide into the next card slot 521 to complete the rotation process.

[0059] Based on the locking of the locking assembly 5, by engaging the engaging teeth 511 with the card slots 521 at different positions, the first bracket 1 can be locked at different opening and closing angles. In this way, it is convenient for the user to fix the first bracket 1 after it is unfolded or folded, so that it can be kept in a stable state to avoid affecting normal use.

[0060] To achieve the fixed connection between the rotating wheel 51 and the first bracket 1, preferably, a connecting plate 513 is integrally formed on one side of the rotating wheel 51, and the connecting plate 513 is locked to the first bracket 1 using screws.

[0061] In one embodiment, referring to Figures 7-8, first guiding surfaces 512 are provided on both sides of the engaging teeth 511, and the first guiding surfaces 512 are used to guide the engaging teeth 511 to rotate and disengage from the card slot 521; and / or, second guiding surfaces 522 are provided on both sides of the card slot 521, and the second guiding surfaces 522 are used to guide the engaging teeth 511 to rotate and disengage from the card slot 521.

[0062] In practical applications, the first guiding surface 512 and the second guiding surface 522 can be used separately or in combination to achieve better results. When both exist, they can cooperate with each other to jointly guide the engaging teeth 511 to smoothly disengage from the card slot 521 and quickly reset after unlocking.

[0063] In one embodiment, the locking assembly 5 further includes an adjusting nut 54 threadedly installed on the rotating shaft 3, and the adjusting nut 54 abuts against the side of the elastic member 53 away from the locking wheel 52.

[0064] The adjusting nut 54 is designed to be threadedly installed on the rotating shaft 3 and can move along the axial direction of the rotating shaft 3. By adjusting the position of the adjusting nut 54 on the rotating shaft 3, the degree of compression of the elastic member 53 can be changed, thereby adjusting the thrust of the elastic member 53 on the locking wheel 52. The elastic force of the elastic member 53 directly affects the meshing tightness between the locking wheel 52 and the rotating wheel 51. If the elastic force is too large, it may cause difficulty in unlocking or damage to components; if the elastic force is too small, the first bracket 1 may not be effectively locked. By rotating the adjusting nut 54, the elastic force of the elastic member 53 can be finely adjusted. When it is necessary to increase the locking force, the adjusting nut 54 is moved forward to compress the elastic member 53; when it is necessary to decrease the locking force, the adjusting nut 54 is moved backward to release the compression of the elastic member 53. After introducing the adjusting nut 54, the locking assembly 5 can be flexibly adjusted according to actual needs. Whether in the production and assembly process or in the subsequent use process, the locking effect can be optimized by adjusting the adjusting nut 54.

[0065] On the other hand, an electronic terminal is provided, including the above-mentioned rotating mechanism.

[0066] The electronic terminal of this embodiment can be a product such as a flip-type smart watch, a smart phone, a laptop computer, a scanning pen, etc.

[0067] Based on the rotating mechanism of this embodiment, the electronic terminal of this embodiment has the advantages of being flip-openable and having good durability.
