Description

Technical Field

[0001] This utility model relates to keyboards, and more particularly to a keyboard with a ratchet eject mechanism. Background Technology

[0002] With the widespread adoption of wireless technology, wireless peripherals such as wireless keyboards and mice have gained popularity due to their convenience. These devices typically come with a USB receiver to establish a wireless connection between the device and the computer. This USB receiver is usually small and easily lost if not properly stored when not in use or when carrying the keyboard.

[0003] To address this issue, existing designs typically incorporate a storage slot in the keyboard casing. Users insert the wireless receiver into this slot, securing it using friction between the components or simple clips. However, this method is generally inconvenient, especially when removing the receiver, which often requires effort to pry or pull it out of the slot using fingernails or tools, resulting in a poor user experience. Summary of the Invention

[0004] This invention aims to at least partially solve one of the technical problems in related technologies. Therefore, the purpose of this invention is to provide a keyboard with a ratchet-type eject mechanism.

[0005] To achieve the above objectives, a keyboard with a ratchet-type ejection mechanism according to an embodiment of the present invention includes: A keyboard case, wherein the side of the keyboard case has an opening for inserting a receiver; A storage stand, which is slidably disposed within the keyboard housing, is used to store the receiver; A ratchet-type ejection mechanism is configured such that when the receiver is inserted into the storage base and pressed once, the storage base is restricted to a retracted position to conceal the receiver within the keyboard housing, and when the receiver is pressed a second time, the storage base is pushed to slide into an extended position to eject the receiver from the opening.

[0006] The keyboard with a ratchet-type pop-out mechanism provided in this embodiment simplifies the storage and retrieval process of the receiver through the designed storage base and ratchet-type pop-out mechanism. A single press locks the storage base inside the keyboard for secure concealment. A second press automatically pops it out for quick and easy access. This improves operational convenience, significantly enhances the user experience, and provides a more user-friendly and efficient storage and retrieval method while ensuring reliable storage and preventing loss.

[0007] In addition, the keyboard with a ratchet eject mechanism according to the above embodiments of the present invention may also have the following additional technical features: According to one embodiment of the present invention, the ratchet ejection mechanism includes: A sleeve is fixed inside the keyboard housing. Multiple locking grooves and multiple releasing grooves are alternately formed on the inner peripheral wall of the sleeve along the axial direction. The depth of the locking groove in the axial direction is smaller than the depth of the releasing groove in the axial direction. A follower is disposed within the sleeve and is capable of axial and rotational movement. The follower is provided with at least one radially protruding follower tooth for selectively engaging with a locking groove or a releasing groove of the sleeve. The follower tooth has a helical tooth surface. A ratchet is linked to the storage seat. One end of the ratchet is provided with a plurality of axially protruding ratchet teeth at circumferential intervals, and the tips of the ratchet teeth abut against the helical tooth surface of the driven member. An elastic element acts on the driven member to provide an axial elastic force toward the ratchet; When the ratchet is pressed, it pushes the driven member to overcome the elastic force of the elastic member and cause axial displacement until the driven tooth disengages from one of the locking groove and the release groove. The elastic member drives the driven member to rebound towards the ratchet. During the rebound, the helical tooth surface of the driven member is abutted and guided by the tip of the ratchet, thereby forcing the driven member to rotate, so that the driven tooth aligns with and enters the other of the locking groove and the release groove, so as to alternately realize the extended position defined by the release groove and the retracted position defined by the locking groove.

[0008] According to one embodiment of the present invention, the ratchet is provided with a first magnetic element, the driven member is provided with a second magnetic element, and the first magnetic element and the second magnetic element are attracted to each other, so that when the driven tooth of the driven member is located in the locking groove, the storage seat and the ratchet are held in the retracted position.

[0009] According to one embodiment of the present invention, the ratchet includes a first end and a second end, the first end is slidably sleeved in the sleeve, the ratchet teeth are located at the second end, the first magnetic element is embedded in the second end, and the second end is pluggably connected to the storage base.

[0010] According to one embodiment of the present invention, the driven member includes a first cylindrical segment and a second cylindrical segment, the first cylindrical segment is slidably sleeved in the sleeve, the driven tooth is located in the first cylindrical segment, the second magnetic member is embedded in the first cylindrical segment, and the second cylindrical segment abuts against the elastic member.

[0025] The keyboard with a ratchet eject mechanism according to an embodiment of the present invention will now be described in detail with reference to the accompanying drawings.

[0026] Reference Figures 1 to 10 As shown, the keyboard with a ratchet eject mechanism provided according to an embodiment of the present invention includes a keyboard shell 10, a storage base 20, and a ratchet eject mechanism 30.

[0027] Specifically, the keyboard housing 10 has an opening H10 on its side for inserting a receiver. For example, the opening H10 may be located on the rear side of the keyboard housing 10. The size and shape of the opening H10 are matched to the receiver so that the receiver can be smoothly inserted into or removed from the opening H10.

[0028] The storage base 20 is slidably disposed within the keyboard housing 10 to store the receiver. For example, a guide rail structure can be provided inside the keyboard housing 10, and a slider or groove that cooperates with it can be provided on the outer wall of the storage base 20, thereby ensuring that the storage base 20 can reciprocate linearly stably and smoothly within a preset stroke.

[0029] The ratchet-type ejection mechanism 30 is configured to restrict the storage base 20 to a retracted position after the receiver is inserted into the storage base 20 and pressed once, so as to hide the receiver inside the keyboard shell 10, and to push the storage base 20 to an extended position when the receiver is pressed a second time, so as to eject the receiver from the opening H10.

[0030] Understandably, the ratchet-type pop-out mechanism 30 can adopt a push-button switch structure, such as a push-lock unlock mechanism similar to that used in the extension and retraction of a ballpoint pen.

[0031] When the user needs to store the receiver, they first insert it into the storage holder 20 located at the opening H10 of the keyboard case 10. Then, the user presses the end of the receiver inward; this pressure is transmitted through the receiver to the storage holder 20, causing the entire storage holder 20 to slide into the keyboard case 10. The user then releases the receiver. During this process, the storage holder 20 pushes the ratchet-type ejection mechanism 30 to the retracted position, where the end of the receiver is flush with or slightly recessed from the side of the keyboard case 10, thus completely and concealing the receiver inside the keyboard, effectively preventing loss.

[0032] When the user needs to remove the receiver, they simply need to press down again on the end of the receiver at the opening H10. This press causes a slight inward displacement of the storage base 20, which is then released. This displacement is sufficient to disengage the ratchet-type ejection mechanism 30, causing it to spring back to the extended position. In this extended position, the receiver ejects a short distance from the opening H10, causing its end to protrude beyond the keyboard housing 10. The user can easily and naturally remove the receiver from the storage base 20 without using fingernails or tools.

[0033] The keyboard with a ratchet-type pop-out mechanism provided in this embodiment of the invention simplifies the storage and retrieval process of the receiver through the storage base 20 and the ratchet-type pop-out mechanism 30. A single press locks the storage base 20 inside the keyboard for secure concealment. A second press automatically pops it out for quick and easy access. This improves operational convenience, significantly enhances the user experience, and provides a more user-friendly and efficient storage and retrieval method while ensuring reliable storage and preventing loss.

[0034] Reference Figures 3 to 10 As shown, in one embodiment of the present invention, the ratchet ejection mechanism 30 includes a sleeve 301, a follower 302, a ratchet 303, and an elastic element 304. The sleeve 301 is fixed inside the keyboard housing 10. Multiple locking grooves H30b and multiple releasing grooves H30a are alternately formed on the inner peripheral wall of the sleeve 301 along the axial direction. The depth of the locking groove H30b in the axial direction is smaller than the depth of the releasing groove H30a in the axial direction.

[0035] In other words, there is a release groove H30a between the two locking grooves H30b, and the locking groove H30b and the release groove H30a are adjacent to each other. The bottom end of the locking groove H30b is shallower in the axial direction, while the bottom end of the release groove H30a is deeper in the axial direction. This difference in depth between the locking groove H30b and the release groove H30a provides two different physical limit points for the axial travel of the follower 302, thereby defining the retracted position and the extended position of the receiving seat 20.

[0036] The driven member 302 is disposed within the sleeve 301 and is capable of axial and rotational movement. The driven member 302 has at least one radially protruding driven tooth 3021 for selectively engaging with the locking groove H30b or releasing groove H30a of the sleeve 301. The driven tooth 3021 has a helical tooth surface S302. The size and shape of the driven tooth 3021 are designed to smoothly embed into the locking groove H30b or releasing groove H30a on the inner wall of the sleeve 301. One side of the driven tooth 3021 is designed with a helical tooth surface S302. This helical tooth surface S302 is a functional surface for achieving force-driven rotation and will cooperate with the ratchet 303.

[0037] The ratchet 303 is linked to the receiving seat 20. One end of the ratchet 303 has a plurality of axially protruding ratchet teeth 3031 spaced circumferentially, the tips of which abut against the helical tooth surface S302 of the driven member 302. Exemplarily, one end of the ratchet 303 is connected to one end of the receiving seat 20, and the other end extends into the sleeve 301 and faces the driven member 302. The end face of the ratchet 303 opposite to the driven member 302 has a plurality of axially protruding ratchet teeth 3031 evenly distributed circumferentially. The tips of these ratchet teeth 3031 can form an effective unidirectional abutment and sliding guide with the helical tooth surface S302 of the driven teeth 3021 on the driven member 302. When the driven member 302 rebounds, the lateral force exerted by the tips of these ratchet teeth 3031 on the helical tooth surface S302 forces the driven member 302 to rotate at a predetermined angle.

[0038] The elastic element 304 acts on the driven member 302, providing an axial elastic force towards the ratchet 303. Utilizing the elastic force provided by the elastic element 304, the driven tooth 3021 of the driven member 302 can remain in abutting position against the ratchet tooth 3031 on the ratchet 303.

[0039] When the ratchet 303 is pressed, it pushes the driven member 302 to overcome the elastic force of the elastic member 304 and undergo axial displacement until the driven tooth 3021 disengages from one of the locking groove H30b and the release groove H30a. The elastic member 304 drives the driven member 302 to rebound towards the ratchet 303. During the rebound, the helical tooth surface S302 of the driven member 302 is abutted and guided by the tip of the ratchet 3031, thereby forcing the driven member 302 to rotate, so that the driven tooth 3021 aligns with and enters the other of the locking groove H30b and the release groove H30a, so as to alternately realize the extended position defined by the release groove H30a and the retracted position defined by the locking groove H30b.

[0040] In practical use, assuming the initial state is the extended position, the driven tooth 3021 of the driven member 302 is located in a relatively deep release groove H30a. When the user presses the receiver for the first time, the receiver pushes the storage seat 20, which in turn pushes the ratchet 303. The ratchet teeth 3031 on the ratchet 303 further push the driven member 302 to move axially inward against the elastic force of the elastic member 304 until the driven tooth 3021 is completely disengaged from the release groove H30a. When the user releases the hand, the pressing force disappears, and the compressed elastic member 304 drives the driven member 302 to rebound outward. During the rebound process, the helical tooth surface S302 of the driven tooth 3021 contacts the tip of the ratchet teeth 3031 of the ratchet 303. Under the action of the axial rebound force, the helical tooth surface S302 slides along the tooth profile of the ratchet teeth 3031, generating a tangential component force. This component force drives the driven member 302 to rotate as a whole by an angle. After rotation, the driven tooth 3021 aligns perfectly with an adjacent shallower locking groove H30b. Subsequently, the driven member 302 continues to spring back until the driven tooth 3021 enters and abuts against the bottom of the locking groove H30b. At this point, the ratchet 303 ejection mechanism is locked, the storage seat 20 remains in the retracted position, and the receiver can be stored and hidden in the keyboard housing 10.

[0041] When the user presses again, the above process repeats, but this time the rotation will align the driven tooth 3021 and enter the next deeper release groove H30a. Under the elastic force of the elastic element 304, the storage seat 20 pops out to the extended position. At this time, the receiver can be extended from the opening H10, and the user can easily take out the receiver.

[0042] The aforementioned ratchet-type ejection mechanism 30 has a clear operational logic. Through the physical limiting of locking grooves H30b and release grooves H30a of varying depths, it directly defines the precise extension and retraction positions, improving operational reliability and positioning accuracy. Furthermore, both the ratchet 303 and the driven member 302 are guided and constrained within the sleeve 301, resulting in smooth and stable operation of the entire mechanism and enhancing overall reliability and stability.

[0043] Reference Figures 5 to 10 As shown, in one embodiment of the present invention, the ratchet 303 is provided with a first magnetic element 305, and the driven member 302 is provided with a second magnetic element 306. The first magnetic element 305 and the second magnetic element 306 are attracted to each other, so that when the driven tooth 3021 of the driven member 302 is located in the locking groove H30b, the storage seat 20 and the ratchet 303 are held in the retracted position.

[0044] When the storage base 20 is pressed to the retracted position, the driven tooth 3021 of the driven member 302 enters the locking groove H30b. In this state, the axial distance between the ratchet 303 and the driven member 302 reaches its minimum. At this time, the magnetic attraction between the first magnetic member 305 and the second magnetic member 306 keeps the ratchet 303 attached to the driven member 302, thereby keeping the storage base 20 in the retracted position and preventing the ratchet 303 from slipping within the sleeve 301 in this situation, thus greatly enhancing the stability of the locked state.

[0045] By adding the aforementioned magnetic adsorption structure, the reliability of the locking mechanism is greatly improved, ensuring that the receiver will not accidentally pop out during transport.

[0046] Preferably, the first magnetic component 305 and the second magnetic component 306 are small, strong permanent magnets, such as neodymium iron boron magnets. During installation, it is necessary to ensure that the opposing surfaces of the first magnetic component 305 and the second magnetic component 306 are of opposite polarities (i.e., N pole to S pole), so that they generate a magnetic force that attracts each other.

[0047] It is understandable that one of the first magnetic component 305 and the second magnetic component 306 is a permanent magnet, while the other of the first magnetic component 305 and the second magnetic component 306 is a metal component that can be attracted by the permanent magnet. In this way, the ratchet 303 can also be attracted together with the driven component 302.

[0048] Reference Figures 7 to 10 As shown, in one embodiment of the present invention, the ratchet 303 includes a first end and a second end. The first end is slidably sleeved in the sleeve 301, the ratchet tooth 3031 is located at the second end, the first magnetic element 305 is embedded in the second end, and the second end is pluggably connected to the storage seat 20.

[0049] During the assembly of the ratchet ejection mechanism, the sleeve 301, the driven component 302, and the ratchet 303 can be pre-assembled together. Then, one end of the ratchet 303 is inserted into the storage base 20 to form a complete module. This simplifies the production assembly process, achieves modular assembly, and significantly improves production efficiency. Simultaneously, it enhances the product's maintainability and scalability, allowing for easy independent replacement of faulty components.

[0050] Reference Figures 7 to 10As shown, in one embodiment of this utility model, the driven member 302 includes a first cylindrical segment 302a and a second cylindrical segment 302b. The first cylindrical segment 302a is slidably sleeved within the sleeve 301. The driven tooth 3021 is located within the first cylindrical segment 302a. The second magnetic member 306 is embedded within the first cylindrical segment 302a. The second cylindrical segment 302b abuts against the elastic member 304. Preferably, the diameter of the first cylindrical segment 302a is larger than the diameter of the second cylindrical segment 302b.

[0051] In this embodiment, the follower 302 adopts a combination design of a first cylindrical segment 302a and a second cylindrical segment 302b. The first cylindrical segment 302a ensures smooth sliding cooperation with the sleeve 301, while the effective constraint of the second cylindrical segment 302b on the spring ensures stable and reliable driving force.

[0052] Reference Figure 7 As shown, in one embodiment of the present invention, the locking groove H30b has an inclined stop surface S301, which is adapted to the inclined tooth surface S302.

[0053] During the return stroke, after the helical tooth surface S302 of the driven member 302 disengages from the release groove H30a, the engagement of the ratchet tooth 3031 of the ratchet and the helical tooth surface S302 of the driven tooth 3021 forces the driven member 302 to rotate. When the driven member 302 rotates a certain angle, the helical tooth surface S302 on the driven member 302 will contact the inclined stop surface S301 of the locking groove H30b and slide along the inclined stop surface S301, eventually fully entering the locking groove H30b. In this way, the guiding effect of the inclined stop surface S301 makes each state switching action more precise and accurate, ensuring that the driven member 302 can smoothly switch from the release groove H30a to the locking groove H30b, thereby improving reliability.

[0054] Reference Figures 3 to 5 As shown, in one embodiment of this utility model, the storage base 20 has a storage cavity, and the side wall of the storage cavity is provided with a window H201. An elastic pressure arm 201 is located within the window H201. One end of the elastic pressure arm 201 is fixed to the storage base 20, and the other end of the elastic pressure arm 201 protrudes into the storage cavity to press against the surface of the receiver in the storage cavity. The elastic pressure arm 201 can be made of the same material as the storage base 20 and integrally formed, or it can be made of other elastic materials, such as an elastic metal sheet, with one end of the elastic metal sheet fixed to the storage base 20.

[0055] When the user pushes the receiver into the storage base 20, the side surface of the receiver will contact and press against the free end of the elastic pressure arm 201. As the receiver continues to be pushed in, the elastic pressure arm 201 is forced to undergo elastic deformation, and its free end deflects outward from the window H201, thereby generating a rebound force that is opposite to the direction of deformation and continuously points inward toward the storage cavity. This rebound force acts directly on the surface of the receiver, forming an effective clamping force that firmly presses the receiver against the opposite inner wall of the storage cavity.

[0056] Through the aforementioned storage base 20 structure, the continuous pressure provided by the elastic pressure arm 201 greatly enhances the stability of the receiver within the storage cavity, effectively preventing the receiver from shaking or producing abnormal noises due to keyboard movement or vibration, thus improving the overall quality of the product. Simultaneously, the elastic compression generates moderate frictional damping, ensuring that the receiver will not accidentally slip out of the storage base 20 due to inertia when it pops out from the keyboard shell 10, enhancing safety during use.

[0057] Reference Figure 2 and Figure 5 As shown, in one embodiment of the present invention, the outer surface of the sleeve 301 has a wing 3011, and the keyboard shell 10 is provided with a locking seat 101. The wing 3011 is locked on the locking seat 101 to fix the sleeve 301 inside the keyboard shell 10.

[0058] Reference Figure 2 As shown, in one embodiment of this utility model, a positioning seat 102 is provided inside the keyboard housing 10, and a positioning post is provided on the positioning seat 102. The elastic element 304 is a spring, one end of which is sleeved on the positioning post, and the other end of which abuts against the driven element 302. In this way, the spring is installed stably and reliably, thereby providing an elastic force with accurate direction.

During the rebound, the helical tooth surface of the driven member is abutted and guided by the tip of the ratchet, thereby forcing the driven member to rotate, so that the driven tooth aligns with and enters the other of the locking groove and the release groove, so as to alternately realize the extended position defined by the release groove and the retracted position defined by the locking groove.
