Description

Technical Field

[0001] This utility model relates to the technical field of gaming peripherals, and in particular to a clamping device and its gaming controller. Background Technology

[0002] With the booming development of the video game industry, game controllers, as important game control devices, have increasingly attracted user attention regarding their functionality and adaptability. Currently, game controllers designed for mobile smart terminals (such as smartphones and tablets) include a clamping device for holding the mobile smart terminal, compared to conventional game controllers. However, existing clamping devices are only compatible with small mobile devices like smartphones, and game controller designs are typically limited to adapting to devices of a single size; this is clearly inadequate for the diverse range of mobile smart terminal sizes on the market. Furthermore, the clamping device often fails to hold the mobile smart terminal securely and stably, easily leading to separation and significantly impacting the user experience. Therefore, there is an urgent need to address these issues. Utility Model Content

[0003] To address the aforementioned issues, this utility model provides a clamping device and its game controller that offers a large clamping range, convenient and quick storage, and relatively secure clamping.

[0004] This utility model provides a clamping device, including a housing, a first limiting mechanism on the housing, a sliding cavity through the housing along a first direction, and a first-stage telescopic member slidably connected to both ends of the sliding cavity; a second limiting mechanism on the first-stage telescopic member, a sliding hole through the first-stage telescopic member along the first direction, a second-stage telescopic member slidably connected in the sliding hole, and a clamping claw protruding from the second-stage telescopic member;

[0005] The first limiting mechanism is used to lock or unlock the primary telescopic member relative to the housing, and the second limiting mechanism is used to lock or unlock the secondary telescopic member relative to the primary telescopic member.

[0006] Furthermore, a gear is rotatably connected inside the housing, and a rack that meshes with the gear is provided on the first-stage telescopic member. The rack extends along the first direction; under the cooperative transmission of the gear and the rack, the two first-stage telescopic members can move towards each other or away from each other, so that they can retract or expand simultaneously.

[0007] Furthermore, the first-level telescopic component is provided with a limiting post, and the second-level telescopic component is provided with a groove that engages with the limiting post. At least two grooves are spaced apart along the first direction. With the engaging engagement of the limiting post and the groove, the second-level telescopic component can be locked relative to the first-level telescopic component, preventing it from sliding freely and ensuring a secure and stable clamping.

[0008] Furthermore, the first limiting mechanism includes a first limiting member and a first elastic member. The first limiting member is provided with a stop tooth, and the first-stage telescopic member is provided with a helical rack adapted to the stop tooth. The helical rack extends along the first direction, and the first elastic member always has the tendency to make the stop tooth engage with the helical rack. The first limiting member is provided with a first knob, and the housing has a first strip hole for the first knob to slide through, and the first knob is exposed to the outside through the first strip hole. Under the engagement of the stop tooth and the helical rack, the first-stage telescopic member can be effectively locked relative to the housing. By operating the first knob, the stop tooth can be disengaged from the helical rack, so that the first-stage telescopic member is unlocked relative to the housing.

[0009] Furthermore, the second limiting mechanism includes a second limiting member and a second elastic member. The second limiting member has a protruding locking block, and the secondary telescopic member has a protruding limiting strip extending along the first direction. The limiting strip has at least two notches spaced apart along the first direction. The second elastic member always has a tendency to allow the locking block to engage in one of the notches. The second limiting member is slidably connected to the primary telescopic member. The second limiting member has a protruding second dial, and the primary telescopic member has a second strip-shaped hole for the second dial to slide through. The second dial passes through the second strip-shaped hole and is exposed to the outside. With the locking engagement of the locking block and the notch, the secondary telescopic member can be effectively locked relative to the primary telescopic member. By operating the second dial, the locking block can be disengaged from the notch to release the engagement, thus releasing the locking state of the secondary telescopic member relative to the primary telescopic member.

[0010] Furthermore, a third elastic element is connected between the housing and the first-stage telescopic member. The third elastic element always tends to keep the two first-stage telescopic members away from each other. Under the action of the third elastic element, the first-stage telescopic member can automatically unfold, making the user operation simpler and faster.

[0011] Furthermore, the inner wall of the sliding cavity is provided with an annular barrier, the third elastic element is housed within the annular barrier, and one end of the third elastic element abuts against the inner wall of the annular barrier. The primary telescopic member is provided with a stop block that abuts against the other end of the third elastic element. By setting the annular barrier, the third elastic element is easy to install and securely connected, so that the primary telescopic member has sufficient tension for automatic expansion.

[0012] Furthermore, the annular enclosure is provided with a guide rod, and the third elastic element is sleeved on the guide rod; this effectively restricts the third elastic element, allowing it to be compressed or stretched only along the guide rod.

[0013] Furthermore, the second dial is provided with a guide slope, and one end of the outer wall of the annular enclosure is positioned opposite to the guide slope; with the cooperation of the outer wall of the annular enclosure and the guide slope, the annular enclosure can push the second dial, thereby automatically releasing the locking state of the secondary telescopic component relative to the primary telescopic component.

[0014] This utility model also provides a game controller with the above-mentioned clamping device. The game controller includes a shell connected to the housing, a circuit board inside the shell, and buttons, a joystick, and a connection port electrically connected to the circuit board on the shell.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows: By setting a first limiting mechanism on the shell and setting first-stage telescopic members at both ends of the sliding cavity, the two first-stage telescopic members can be extended outward during actual use, thereby clamping smaller devices. Under the action of the first limiting mechanism, the first-stage telescopic members can be locked relative to the shell, maintaining a secure and stable clamping and preventing the clamped device from accidentally falling off. For larger devices, the second-stage telescopic members can be extended after the first-stage telescopic members are extended, thus clamping larger devices. Under the action of the second limiting mechanism, the second-stage telescopic members can be extended... The first and second telescopic components are locked together to ensure a secure and stable clamping experience, effectively improving the user experience and feel, thus solving the technical problems in the prior art. Furthermore, the first and second limiting mechanisms allow the first and second telescopic components to be unlocked, allowing them to retract or be stored inside the housing, keeping the entire clamping device and game controller compact for easy storage and portability. Overall, this invention offers advantages such as a large clamping range, convenient and quick storage, and secure and stable clamping, making it compatible with mobile smart terminals of various sizes while effectively ensuring a good user experience and feel.

Detailed Implementation

[0026] To facilitate understanding of this utility model, a more detailed description is provided below with reference to the accompanying drawings and specific embodiments. It should be noted that when an element is described as being "fixed to" another element, it can be directly on the other element, or one or more intermediate elements may exist between them. When an element is described as being "connected" to another element, it can be directly connected to the other element, or one or more intermediate elements may exist between them. The terms "upper," "lower," "left," "right," "inner," "outer," and similar expressions used in this specification are for illustrative purposes only.

[0027] Unless otherwise defined, all technical and scientific terms used in this specification have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to limit the scope of the invention. The term "and / or" as used in this specification includes any and all combinations of one or more of the associated listed items.

[0028] like Figures 1 to 6 As shown, this utility model protects a clamping device, including a housing 1, a first limiting mechanism 2 on the housing 1, a sliding cavity 1.1 extending through the housing 1 in a first direction, and a primary telescopic member 3 slidably connected to both ends of the sliding cavity 1.1; a second limiting mechanism 4 on the primary telescopic member 3, a sliding hole 3.1 extending through the primary telescopic member 3 in the first direction, a secondary telescopic member 5 slidably connected in the sliding hole 3.1, and a clamping claw 5.1 protruding from the secondary telescopic member 5;

[0029] The first limiting mechanism 2 is used to lock or unlock the primary telescopic member 3 relative to the housing 1, and the second limiting mechanism 4 is used to lock or unlock the secondary telescopic member 5 relative to the primary telescopic member 3.

[0030] A gear 6 is rotatably connected inside the housing 1. A rack 7 that meshes with the gear 6 is provided on the primary telescopic member 3. The rack 7 extends along the first direction and is integrally formed with the primary telescopic member 3. Specifically, a rotating shaft 1.4 for mounting the gear 6 is protruding from the center of the sliding cavity 1.1. Two racks 7 are spaced apart in the second direction and both mesh with the gear 6, so that the two primary telescopic members 3 can move towards or away from each other, causing them to retract or expand simultaneously.

[0031] The primary telescopic member 3 has a limiting post 8 inside, and the secondary telescopic member 5 has a groove 5.2 that engages with the limiting post 8. At least two grooves 5.2 are spaced apart along a first direction. Preferably, both sides of the secondary telescopic member 5 have grooves 5.2, and the limiting post 8 is also correspondingly provided. The mating surface between the groove 5.2 and the limiting post 8 is hemispherical. During the actual extension or retraction of the secondary telescopic member 5, when the limiting post 8 disengages from the groove 5.2, the locking state is released. At this time, the secondary telescopic member 5 can slide relative to the primary telescopic member 3, and a certain amount of plastic deformation will occur at the limiting post 8 of the primary telescopic member 3. When the limiting post 8 re-engages into the groove 5.2, the locking state is re-established. Under the elastic force of the plastic deformation, the limiting post 8 is securely engaged in the groove 5.2. To induce plastic deformation in the primary telescopic member 3 and disengage the limiting post 8 from the groove 5.2, the user needs to apply a certain force. Therefore, the limiting post 8 can be securely engaged in the groove 5.2. It is worth mentioning that, for reference Figure 6As shown, in this embodiment, there are two grooves 5.2 on the same side, corresponding to the initial position and the maximum stroke position of the secondary telescopic member 5; of course, more grooves 5.2 can also be set between the two positions for a stronger sense of segmentation.

[0032] The first limiting mechanism 2 includes a first limiting member 2.1 and a first elastic member 2.2. The first limiting member 2.1 is provided with a stop tooth 2.11, and the first-stage telescopic member 3 is provided with a helical rack 3.2 adapted to the stop tooth 2.11. The helical rack 3.2 extends along the first direction, and the first elastic member 2.2 always has the tendency to allow the stop tooth 2.11 to engage with the helical rack 3.2. The first limiting member 2.1 is provided with a first dial 2.12 protruding, and the housing 1 is provided with a first strip hole 1.2 for the first dial 2.12 to slide. The first dial 2.12 passes through the first strip hole 1.2 and is exposed to the outside.

[0033] Preferably, the first limiting member 2.1 has a clearance hole 2.13 for the rotating shaft 1.4 to pass through. The clearance hole 2.13 is an oblong or elongated hole to facilitate the sliding of the first limiting member 2.1 to switch between locked and unlocked states. The first limiting member 2.1 extends along the second direction. Inside the sliding cavity 1.1, along the second direction, is a first sliding groove 1.5 for the first limiting member 2.1 to slide. A first elongated hole 1.2 connects to the bottom of the first sliding groove 1.5 and is formed along the second direction. Connecting posts 15 protrude from the side wall of the sliding cavity 1.1 and the end of the first limiting member 2.1, respectively. The two ends of the first elastic member 2.2 are respectively sleeved on the two connecting posts 15, which can make the first elastic member 2.2 securely connected and ensure the driving force of the first limiting member 2.1. The first elastic member 2.2 is preferably a columnar spring.

[0034] When the first limiting mechanism 2 is actually working, under normal circumstances, under the elastic force of the first elastic element 2.2, the stop tooth 2.11 is locked in the helical rack 3.2, so that the first-stage telescopic member 3 is locked relative to the housing 1. At this time, the two first-stage telescopic members 3 cannot slide relative to the sliding cavity 1.1. When it is necessary to unfold the first-stage telescopic member 3, by operating the first dial 2.12, the first dial 2.12 slides in the first strip hole 1.2, and the entire first limiting member 2.1 slides in the first sliding groove 1.5. At the same time, it overcomes the elastic force of the first elastic element 2.2, so that the stop tooth 2.11 moves away from the helical rack 3.2, so that the first-stage telescopic member 3 is unlocked relative to the housing 1. At this time, the two first-stage telescopic members 3 can slide relative to the sliding cavity 1.1.

[0035] It is worth mentioning that, since the mating surface between the helical rack 3.2 and the stop tooth 2.11 is an inclined surface, the first-stage telescopic member 3 can move in one direction (towards the inside of the sliding cavity 1.1). Even in the locked state, if the user applies a certain force to the first-stage telescopic member 3, it can slide towards the inside of the sliding cavity 1.1, allowing the two first-stage telescopic members 3 to move closer to each other to fit the shape and size of the mobile smart terminal.

[0036] The second limiting mechanism 4 includes a second limiting member 4.1 and a second elastic member 4.2. The second limiting member 4.1 has a protruding locking block 4.11. The secondary telescopic member 5 has a protruding limiting strip 5.3 extending along a first direction. The limiting strip 5.3 has at least two notches 5.4 spaced apart along the first direction. The second elastic member 4.2 always tends to allow the locking block 4.11 to engage with one of the notches 5.4. The second limiting member 4.1 is slidably connected to the primary telescopic member 3. The second limiting member 4.1 has a protruding second dial 4.12. The primary telescopic member 3 has a second strip-shaped hole 3.3 for the second dial 4.12 to slide through, and the second dial 4.12 passes through the second strip-shaped hole 3.3 and is exposed to the outside. It is worth mentioning that, according to reference... Figure 6 As shown, in this embodiment, there are two notches 5.4 on the same limiting strip 5.3, which correspond to the initial position and the maximum stroke position of the secondary telescopic member 5; of course, more notches 5.4 can also be set between the two positions for a stronger sense of segmentation.

[0037] Preferred, Reference Figure 2 As shown, the primary telescopic member 3 has a second sliding groove 3.5 along the second direction for sliding connection of the second limiting member 4.1. The second strip hole 3.3 connects to the bottom of the second sliding groove 3.5 and is opened along the second direction. Mounting posts 4.3 are provided at both ends of the second limiting member 4.1 and are connected to the primary telescopic member 3. The second elastic member 4.2 is preferably a torsion spring. The second elastic member 4.2 is installed on both mounting posts 4.3. One end of the second elastic member 4.2 abuts against the end of the second limiting member 4.1, and the other end of the second elastic member 4.2 abuts against the inner wall of the sliding hole 3.1.

[0038] When the second limiting mechanism 4 is in operation, under normal circumstances, under the elastic force of the two second elastic elements 4.2, the locking block 4.11 is locked in one of the notches 5.4, so that the secondary telescopic member 5 is locked relative to the primary telescopic member 3. At this time, the secondary telescopic member 5 cannot slide relative to the primary telescopic member 3. When it is necessary to unfold the secondary telescopic member 5, by operating the second dial 4.12, the second dial 4.12 slides in the second strip hole 3.3, and the entire second limiting member 4.1 slides in the second slide groove 3.5. At the same time, it overcomes the elastic force of the second elastic element 4.2, allowing the locking block 4.11 to leave the notch 5.4, so that the secondary telescopic member 5 is unlocked relative to the primary telescopic member 3. At this time, the secondary telescopic member 5 can slide relative to the primary telescopic member 3, thereby further extending and clamping a larger mobile smart terminal.

[0039] Preferably, the gripping claws 5.1 are C-shaped, and the two gripping claws 5.1 are arranged opposite each other, which can more firmly grip the mobile smart terminal. The gripping claws 5.1 are arranged at right angles to the secondary telescopic member 5, and the gripping claws 5.1 extend upward along the third direction, extending from the top of the housing 1. It should be noted that the first direction, the second direction, and the third direction are mutually perpendicular, and two of these directions correspond to a plane, which is equivalent to the X-axis, Y-axis, and Z-axis.

[0040] Preferably, in some embodiments, a limiting block 5.5 is protruding at the end of the secondary telescopic member 5 and at the other end opposite to the clamping claw 5.1, and a stop bar 16 is installed on the corresponding primary telescopic member 3. When the secondary telescopic member 5 extends outward to its maximum stroke, the stop bar 16 will abut against the limiting block 5.5 to prevent the secondary telescopic member 5 from continuing to extend outward, avoid falling, and ensure a reliable connection.

[0041] refer to Figure 2 As shown, a third elastic element 9 connects the housing 1 and the first-stage telescopic member 3. The third elastic element 9 always tends to keep the two first-stage telescopic members 3 away from each other. An annular barrier 1.3 protrudes from the inner wall of the sliding cavity 1.1. The third elastic element 9 is housed within the annular barrier 1.3, and one end of the third elastic element 9 abuts against the inner wall of the annular barrier 1.3. A stop block 3.4 protrudes from the first-stage telescopic member 3 and abuts against the other end of the third elastic element 9.

[0042] It is worth mentioning that under the action of the third elastic element 9, and when the first limiting mechanism 2 releases the locking state of the first-level telescopic element 3, the first-level telescopic element 3 will automatically extend, without the user having to pull the first-level telescopic element 3, making the operation simple and quick.

[0043] refer to Figure 2As shown, a guide rod 10 is provided inside the annular enclosure 1.3, and a third elastic element 9 is sleeved on the guide rod 10. A guide slope 4.13 is provided on the second dial 4.12, and one end of the outer wall of the annular enclosure 1.3 is positioned opposite to the guide slope 4.13. Preferably, the surfaces of the annular enclosure 1.3 and the guide slope 4.13 that mate are also sloped, making the fit tighter and the pushing smoother. When the guide ramp 4.13 is in operation, both the primary telescopic component 3 and the secondary telescopic component 5 are in the extended state. The user only needs to push the secondary telescopic component 5 inward. Since both are in the locked state, the primary telescopic component 3 will retract inward first under the cooperation of the helical rack 3.2 and the stop tooth 2.11 until the guide ramp 4.13 abuts against the outer wall of the annular barrier 1.3, thereby pushing the second dial 4.12 to move in the second direction, thereby releasing the lock on the secondary telescopic component 5. At this time, the secondary telescopic component 5 can also retract until the entire clamping device is fully retracted. It can be seen that during the entire retraction process, the retraction can be completed without operating the first dial 2.12 or the second dial 4.12, which is convenient and quick to operate.

[0044] Preferably, a plurality of spaced first guide strips 1.6 are provided on the inner wall of the sliding cavity 1.1 along the first direction. Correspondingly, a matching first guide groove 3.6 is provided on the outer wall of the first-stage telescopic member 3, which can effectively ensure the stability and reliability of the first-stage telescopic member 3 during contraction and extension. Similarly, a plurality of spaced second guide strips 3.7 are provided on the inner wall of the sliding hole 3.1 along the first direction. Correspondingly, a matching second guide groove 5.5 is provided on the outer wall of the second-stage telescopic member 5, which can effectively ensure the stability and reliability of the second-stage telescopic member 5 during contraction and extension.

[0045] The working principle of this utility model is as follows: When clamping a mobile phone or other small mobile smart terminals, sliding the first toggle switch 2.12 releases the lock on the first-stage telescopic member 3, allowing it to slide freely relative to the sliding cavity 1.1. In some embodiments, a third elastic member 9 automatically extends the first-stage telescopic member 3, eliminating the need for the user to pull it open. The mobile smart terminal is then placed between the two clamping claws 5.1, and the first-stage telescopic member 3 is pushed inward until the clamping claws 5.1 abut against the side of the mobile smart terminal, locking the first-stage telescopic member 3 again, thus completing the clamping process. When removing a small mobile smart terminal, sliding the first toggle switch 2.12 releases the lock on the first-stage telescopic member 3, and the third elastic member 9 causes the two clamping claws 5.1 to spring open, allowing the small mobile smart terminal to be removed. Pressing the first-stage telescopic member 3 then closes it, thus storing the game controller.

[0046] When clamping tablets and other large mobile smart terminals, first pull the clamping claws 5.1 on both sides. You will hear a "click" sound. The second switch 4.12 locks the secondary telescopic component 5. Then slide the first switch 2.12 to release the lock on the primary telescopic component 3. The primary telescopic component 3 will automatically spring open under the action of the third elastic component 9. Then place the large mobile smart terminal between the two clamping claws 5.1 and push the secondary telescopic component 5 inward until the clamping claws 5.1 abut against the side of the mobile smart terminal to complete the clamping. When removing a large mobile smart terminal, slide the first switch 2.12 to release the lock on the first-stage telescopic component 3. The third elastic component 9 will cause the two gripping claws 5.1 to spring open (the second-stage telescopic component 5 will remain in the extended state), allowing the large mobile smart terminal to be removed. Then press the second-stage telescopic component 5, and the first-stage telescopic component 3 will retract first (at this time, the stop tooth 2.11 will make a "click, click, click" sound with the rack 7). When only 1-2 teeth of the rack 7 remain, the second-stage telescopic component 5 will quickly retract under the pressure (the second switch 4.12 will be held in place and will not make a "click" sound). Continue pressing, and the last 1-2 teeth of the rack 7 will close, and the game controller will be fully stored.

[0047] refer to Figures 1 to 9 As shown, this utility model also protects a game controller with the aforementioned clamping device. The game controller includes a housing 11 connected to a shell 1, a circuit board inside the housing 11, and buttons 12, a joystick 13, and a connection port 14 electrically connected to the circuit board on the housing 11. It is worth noting that game controllers are usually sold or used in pairs, clamped to both sides of a mobile smart terminal during use, corresponding to the user's hands, providing a more secure and stable grip. A detachable connection structure can be provided between the two game controllers for easy storage and for clamping small-sized mobile smart terminals.

[0048] Preferably, the housing 1 is formed by connecting an upper housing and a lower housing in a detachable manner (see reference). Figure 2 As shown, the upper shell is detached from the lower shell, which facilitates manufacturing and installation / disassembly. Similarly, the outer shell 11 also has a detachably connected bottom shell and top shell, which are connected to the lower shell in a detachable manner.

[0049] In summary, the technical solution of this utility model can fully and effectively achieve the aforementioned objectives. Furthermore, the structure and functional principles of this utility model have been fully verified in the embodiments, achieving the expected effects and objectives. Without departing from the principles and essence of this utility model, various changes or modifications can be made to the embodiments. Therefore, this utility model includes all substitutions within the scope mentioned in the patent application claims, and any equivalent changes made within the scope of this patent application are within the scope of the patent application.
