Description

Technical Field

[0001] This utility model relates to the field of microcomputer technology, and in particular to a door cover structure and a microcomputer. Background Technology

[0002] Consumer electronics products such as MiniPCs often have decorative covers over their interfaces. On one hand, exposed ports like USB, HDMI, and Ethernet ports are prone to dust accumulation, which can lead to poor contact or short circuits. These covers physically isolate the interfaces from dust, protecting them. On the other hand, some commercial MiniPCs have covers with locks to prevent unauthorized access to storage devices or networks, enhancing MiniPC security.

[0003] The door cover structure needs to be easy to open during use, allowing for the insertion of cables via an interface. Existing door cover structures often involve snapping the entire door cover onto a microcomputer host, which is relatively difficult to assemble and disassemble, and can easily lead to breakage of the snap-fit ​​joint during this process. Utility Model Content

[0004] The main purpose of this utility model is to propose a door cover structure and a microcomputer, which aims to facilitate the convenient opening and closing of the door cover when the user uses the microcomputer.

[0005] To achieve the above objectives, the door cover structure proposed in this utility model includes:

[0006] A housing having a first through hole;

[0007] A door cover, which is rotatably connected to the housing, and a snap-fit ​​portion is provided on the side of the door cover facing the housing;

[0008] A switch structure includes a snap-fit ​​plate and a first elastic element. The snap-fit ​​plate is connected to the side of the housing facing away from the door cover. The snap-fit ​​plate has a second through hole. The first elastic element connects the housing and the snap-fit ​​plate.

[0009] When the fastening plate is under force, it moves along the length of the housing, causing the first elastic element to undergo elastic deformation. The first through hole and the second through hole coincide. The snap-fit ​​part can pass through the first through hole and the second through hole. When the first elastic element is reset, it drives the fastening plate to snap into the snap-fit ​​part, thereby realizing the connection between the door cover and the housing.

[0010] In one embodiment, the housing is provided with a first guide member facing the fastening plate, and the fastening plate is provided with a second guide member on the side facing the housing. The first guide member and the second guide member are correspondingly engaged and extend along the length direction of the housing.

[0011] In one embodiment, the first guide member is one of a guide block and a guide hole, and the second guide member is the other of the two.

[0012] In one embodiment, the first elastic element is a tension spring or a compression spring.

[0013] In one embodiment, the switch structure further includes a push switch connected to the housing. The push switch has a first mating surface on the side facing the fastening plate, and the fastening plate has a second mating surface on the side facing the push switch. The first mating surface abuts against the second mating surface so that the push switch can push the fastening plate to move.

[0014] In one embodiment, both the first mating surface and the second mating surface are inclined surfaces.

[0015] In one embodiment, the switch structure further includes a second elastic element. A guide post is provided on the side of the push switch facing the housing, and a guide hole is correspondingly formed on the side of the housing facing the push switch. The guide post is inserted into the guide hole, and the second elastic element is sleeved on the guide post. The two ends of the second elastic element abut against the housing and the push switch respectively in the axial direction.

[0016] In one embodiment, a limiting buckle is provided on the side of the push switch facing the housing, and a limiting hole is formed on the side of the housing facing the push switch. The limiting buckle is inserted into the limiting hole and can hook and cooperate with the edge of the limiting hole to prevent the push switch from disengaging from the housing.

[0017] In one embodiment, the door cover is provided with a pivot, and the housing is formed with a pivot hole. The pivot is inserted into the pivot hole so that the door cover can rotate relative to the housing. The pivot is fitted with a torsion spring, and the two ends of the torsion spring abut against the door cover and the housing, respectively.

[0018] This utility model also proposes a microcomputer, the microcomputer including a door cover structure, the door cover structure including:

[0019] The housing has a first through hole;

[0020] A door cover, which is rotatably connected to the housing, and a snap-fit ​​portion is provided on the side of the door cover facing the housing;

[0021] A switch structure includes a snap-fit ​​plate and a first elastic element. The snap-fit ​​plate is connected to the side of the housing facing away from the door cover. The snap-fit ​​plate has a second through hole. The first elastic element connects the housing and the snap-fit ​​plate.

[0022] When the fastening plate is under force, it moves along the length of the housing, causing the first elastic element to undergo elastic deformation. The first through hole and the second through hole coincide. The snap-fit ​​part can pass through the first through hole and the second through hole. When the first elastic element is reset, it drives the fastening plate to snap into the snap-fit ​​part, thereby realizing the connection between the door cover and the housing.

[0023] This utility model provides a door cover structure, including a housing, a door cover, and a switch structure. The housing has a first through hole, which provides a channel for the door cover to engage with the housing. The door cover is mounted on the housing via a rotatable connection and can rotate relative to the housing around a connecting shaft to open or close the opening. A latching portion, a protruding structure, is provided on the side of the door cover facing the housing; its size matches the first through hole and is used to engage with the switch structure when the door cover is closed. The switch structure controls the locking or unlocking of the door cover and the housing. The switch structure includes a latching plate and a first elastic element. The latching plate is connected to the side of the housing facing away from the door cover, i.e., the inner side of the housing, and has a second through hole matching the size of the first through hole. The first elastic element connects the housing and the latching plate, providing a restoring force for the latching plate.

[0024] When the door needs to be closed, rotate the door to bring it closer to the housing while applying force to the latching plate. Under this force, the latching plate moves along the length of the housing. At this time, the first elastic element undergoes elastic deformation and stores elastic potential energy. As the latching plate moves, the first through hole and the second through hole gradually overlap, allowing the locking part to pass through the first and second through holes. Then, release the latching plate, the first elastic element releases its elastic potential energy and resets, causing the latching plate to move in the opposite direction, so that the side wall of the second through hole of the latching plate forms a latching engagement with the locking part, thereby locking the locking part in the through hole and achieving a stable connection between the door and the housing. Conversely, when the door needs to be opened, simply apply force to the latching plate to make the first and second through holes overlap, causing the latching plate to disengage from the locking part, thus lifting and opening the door.

[0025] In this solution, the door cover is locked by the movement of the snap-fit ​​plate and the reset of the elastic element. The direct cooperation of the mechanical structure transmits force and motion, eliminating the need for complex electronic control components. This not only reduces manufacturing costs but also improves the stability and durability of the structure. It can reliably control the opening and closing of the door cover in various environments, thus improving the convenience of opening and closing the door cover. Attached Figure Description

[0038] Consumer electronics products such as MiniPCs often have decorative covers over their interfaces. On one hand, exposed ports like USB, HDMI, and Ethernet ports are prone to dust accumulation, which can lead to poor contact or short circuits. These covers physically isolate the interfaces from dust, protecting them. On the other hand, some commercial MiniPCs have covers with locks to prevent unauthorized access to storage devices or networks, enhancing MiniPC security.

[0039] The door cover structure needs to be easy to open during use, allowing for the insertion of cables via an interface. Existing door cover structures often involve snapping the entire door cover onto a microcomputer host, which is relatively difficult to assemble and disassemble, and can easily lead to breakage of the snap-fit ​​joint during this process.

[0040] To solve the above problems, please refer to... Figures 1 to 4This utility model proposes a door cover structure 100, including a housing 1, a door cover 2, and a switch structure 3. The housing 1 has a first through hole 1a. The door cover 2 is rotatably connected to the housing 1, and a snap-fit ​​part 21 is provided on the side of the door cover 2 facing the housing 1. The switch structure 3 includes a fastening plate 31 and a first elastic member 32. The fastening plate 31 is connected to the side of the housing 1 facing away from the door cover 2, and the fastening plate 31 has a second through hole 31a. The first elastic member 32 connects the housing 1 and the fastening plate 31. When the fastening plate 31 is under force, it moves along the length direction of the housing 1, causing the first elastic member 32 to undergo elastic deformation. The first through hole 1a and the second through hole 31a coincide, and the snap-fit ​​part 21 can pass through the first through hole 1a and the second through hole 31a. When the first elastic member 32 is reset, it drives the fastening plate 31 to engage with the snap-fit ​​part 21, thereby realizing the connection between the door cover 2 and the housing 1.

[0041] The present invention provides a door cover structure 100, comprising a housing 1, a door cover 2, and a switch structure 3. The housing 1 has a first through hole 1a, which provides a channel for the door cover 2 to engage with the housing 1. The door cover 2 is mounted on the housing 1 via a rotatable connection and can rotate relative to the housing 1 around a connecting shaft to open or close the opening. The side of the door cover 2 facing the housing 1 has a latching portion 21, which is a protruding structure whose size is adapted to the first through hole 1a, for engaging with the switch structure 3 when the door cover 2 is closed. The switch structure 3 is used to control the locking or unlocking of the door cover 2 and the housing 1. The switch structure 3 includes a fastening plate 31 and a first elastic member 32. The fastening plate 31 is connected to the side of the housing 1 facing away from the door cover 2, that is, the inner side of the housing 1, and a second through hole 31a matching the size of the first through hole 1a is formed on the fastening plate 31. The first elastic member 32 is connected between the housing 1 and the fastening plate 31 to provide a reset elastic force for the fastening plate 31.

[0042] When the door cover 2 needs to be closed, rotate the door cover 2 to gradually approach the housing 1, and at the same time apply force to the fastening plate 31. Under the force, the fastening plate 31 moves along the length of the housing 1. At this time, the first elastic element 32 generates elastic deformation and stores elastic potential energy. As the fastening plate 31 moves, the first through hole 1a and the second through hole 31a gradually overlap, and the locking part 21 can pass through the first through hole 1a and the second through hole 31a. Then, release the fastening plate 31, the first elastic element 32 releases elastic potential energy and resets, and drives the fastening plate 31 to move in the opposite direction, so that the side wall of the second through hole 31a of the fastening plate 31 forms a fastening fit with the locking part 21, thereby locking the locking part 21 in the through hole and realizing a stable connection between the door cover 2 and the housing 1. Conversely, when it is necessary to open the door cover 2, it is only necessary to apply force to the latching plate 31 so that the first through hole 1a and the second through hole 31a coincide, and the latching plate 31 disengages from the snap-fit ​​part 21, thereby lifting and opening the door cover 2.

[0043] In this solution, the door cover 2 is locked by the movement of the snap-fit ​​plate 31 and the reset of the elastic element. The direct cooperation of the mechanical structure transmits force and movement, eliminating the need for complex electronic control components. This not only reduces manufacturing costs but also improves the stability and durability of the structure. It can stably control the opening and closing of the door cover 2 in various environments, thus improving the convenience of opening and closing the door cover 2.

[0044] In an alternative embodiment, please refer to Figure 3 and Figure 4 To ensure the stability of the fastening plate 31 during movement and prevent it from shifting or jamming, the housing 1 has a first guide member 11 facing the fastening plate 31, and a second guide member 311 is provided on the side of the fastening plate 31 facing the housing 1. The first guide member 11 and the second guide member 311 cooperate with each other and extend along the length direction of the housing 1. The arrangement of the first guide member 11 and the second guide member 311 forms the movement guide path of the fastening plate 31, ensuring that the fastening plate 31 can only move along the preset length direction of the housing 1, thereby improving the accuracy of the operation of the switch structure 3.

[0045] Specifically, the cooperation of the first guide member 11 and the second guide member 311 can limit the displacement of the fastening plate 31 in the direction perpendicular to the movement, preventing the fastening plate 31 from tilting or jamming due to uneven force. For example, when the fastening plate 31 is subjected to the pressure of the snap-fit ​​part 21 or the tension of the first elastic member 32, the guide member can disperse part of the lateral force, ensuring that the fastening plate 31 always moves in a straight line, thereby ensuring that the first through hole 1a and the second through hole 31a can accurately coincide, improving the reliability of the door cover 2 fastening. At the same time, the cooperation of the first guide member 11 and the second guide member 311 can also reduce the friction and wear between the fastening plate 31 and the housing 1, extending the service life of the door cover structure 100.

[0046] In an alternative embodiment, please refer to Figure 3 and Figure 4 The first guide member 11 is one of a guide block and a guide hole, and the second guide member 311 is the other one. For example, if the first guide member 11 is a guide hole extending along the length of the housing 1, then the second guide member 311 is a guide block disposed on the fastening plate 31 and adapted to the guide hole, the guide block being inserted into the guide hole and sliding along the extension direction of the guide hole; or, the first guide member 11 is a guide block, and the second guide member 311 is a guide hole that cooperates with the guide block, which can also achieve a sliding fit between the two, and the specific choice can be made according to actual needs.

[0047] The guide block and guide hole have a simple and easy-to-manufacture structure. The width of the guide block is slightly smaller than the width of the guide hole to ensure smooth sliding while avoiding wobbling caused by excessive clearance. The guide block can be cylindrical or square, and the cross-sectional shape of the guide hole matches that of the guide block. The length of both should cover the maximum travel of the snap-fit ​​plate 31 to ensure effective guidance throughout the entire movement of the snap-fit ​​plate 31. This structural design further improves the stability of the snap-fit ​​plate 31's movement and ensures the overlap accuracy of the first through hole 1a and the second through hole 31a, thereby guaranteeing the reliability of the door cover 2's snap-fit.

[0048] In an alternative embodiment, please refer to Figure 3 The first elastic element 32 is a tension spring or a compression spring. Both tension springs and compression springs are common elastic elements with good elastic restoring performance. The appropriate type can be selected according to the force direction of the fastening plate 31 and the installation space.

[0049] Specifically, in this embodiment, a tension spring is used as the first elastic element 32. One end of the tension spring is connected to the housing 1, and the other end is connected to the fastening plate 31. When the fastening plate 31 is moved under force, the tension spring is stretched and generates elastic tension. After the external force is released, the tension of the tension spring drives the fastening plate 31 to reset. At this time, the initial position of the fastening plate 31 is that it is engaged with the snap-fit ​​part 21. After being moved under force, the through hole coincides. After being released, the tension spring pulls the fastening plate 31 to reset and achieve locking. If a compression spring is used as the first elastic element 32, the two ends of the compression spring abut against the housing 1 and the fastening plate 31 respectively. When the fastening plate 31 is moved under force, it compresses the compression spring, which generates elastic thrust. After the external force is released, the compression spring pushes the fastening plate 31 to reset. The elastic coefficients of the tension spring and the compression spring can be selected according to the required fastening force to ensure that the door cover 2 can be stably locked and easily unlocked during operation. The specific selection can be made according to actual needs.

[0050] In an alternative embodiment, please refer to Figures 1 to 5 To improve the ease of unlocking the door cover 2, the switch structure 3 also includes a push switch 33. The push switch 33 is connected to the housing 1. The push switch 33 has a first mating surface on the side facing the fastening plate 31, and the fastening plate 31 has a second mating surface on the side facing the push switch 33. The first mating surface and the second mating surface abut against each other so that the push switch 33 can push the fastening plate 31 to move.

[0051] The push-button switch 33 converts the user's pressing operation into the movement power of the latching plate 31, enabling unlocking without direct contact with the latching plate 31, thus improving the user experience. When the user needs to open the door cover 2, pressing the push-button switch 33 moves inward into the housing 1. The first mating surface pushes the second mating surface, causing the latching plate 31 to move along the length of the housing 1. This causes the first elastic element 32 to deform, aligning the first through hole 1a with the second through hole 31a. At this point, the latching part 21 loses its latching restriction, and the door cover 2 can be opened. After releasing the push-button switch 33, under the action of the first elastic element 32, the latching plate 31 moves in the opposite direction and pushes the push-button switch 33 back to its original position, awaiting the next latching operation. The push-button switch 33 makes the unlocking operation of the door cover 2 more intuitive and effortless, suitable for various scenarios requiring frequent opening and closing.

[0052] In an optional embodiment, both the first and second mating surfaces are inclined planes. The inclined planes convert the vertical movement of the push switch 33 (along the thickness direction of the housing 1) into the horizontal movement of the latching plate 31 (along the length direction of the housing 1), achieving a change in force direction and improving ease of operation. The inclination angle of the inclined planes can be designed according to actual needs, typically between 30° and 60°, ensuring sufficient force transmission efficiency while avoiding jamming due to an excessively small angle or excessive travel due to an excessively large angle. The first and second mating surfaces have the same inclination angle and fit together. When the push switch 33 is pressed, the two inclined planes slide against each other, and a portion of the axial force of the push switch 33 acts as a component force along the moving direction of the latching plate 31, pushing the latching plate 31 to move. This inclined plane mating structure is simple to manufacture, has high mating precision, ensures smooth pressing operation, reduces wear between mating surfaces, and extends the service life of the switch structure 3.

[0053] In an optional embodiment, to facilitate the automatic reset of the push switch 33, the switch structure 3 further includes a second elastic element 34. The push switch 33 has a guide post 331 on the side facing the housing 1, and a guide hole is formed on the side of the housing 1 facing the push switch 33. The guide post 331 is inserted into the guide hole to guide the movement of the push switch 33. The second elastic element 34 is sleeved on the guide post 331, and its two axial ends abut against the housing 1 and the push switch 33 respectively.

[0054] When the user presses switch 33, switch 33 moves into housing 1 against the elastic force of second elastic element 34, and guide post 331 slides along guide hole to ensure the accuracy of the movement direction of switch 33. After the user releases the press, second elastic element 34 releases its elastic potential energy, pushing switch 33 to move in the opposite direction and return to its initial position. Second elastic element 34 is a compression spring, and its elastic coefficient should be selected according to the pressing feel requirements to ensure easy pressing and rapid return. The mating length of guide post 331 and guide hole covers the maximum stroke of switch 33 to avoid shaking or deviation during pressing, further improving the stability of switch 33 operation.

[0055] In an alternative embodiment, please refer to Figure 5 To prevent the push switch 33 from detaching from the housing 1 when it is reset under the action of the second elastic element 34, a limit buckle 332 is provided on the side of the push switch 33 facing the housing 1. A limit hole is formed on the side of the housing 1 facing the push switch 33. The limit buckle 332 is inserted into the limit hole and can be hooked and engaged with the edge of the limit hole.

[0056] The limit buckle 332 has a hook-shaped structure with a protrusion at its free end and a step or groove on the edge of the limiting hole that mates with the protrusion. When the push switch 33 returns to its maximum stroke, the protrusion of the limit buckle 332 hooks onto the edge of the limiting hole, restricting the push switch 33 from moving further and preventing it from falling off the housing 1. This ensures that the push switch 33 remains reliably connected to the housing 1 during pressing and resetting. This limiting structure is simple and reliable, requiring no additional fixing components. It ensures the normal movement of the push switch 33 while effectively improving the safety and reliability of the structure.

[0057] In an optional embodiment, the door cover 2 is provided with a pivot, and the housing 1 is formed with a pivot hole. The pivot is inserted into the pivot hole so that the door cover 2 can rotate relative to the housing 1. A torsion spring is sleeved on the pivot, and the two ends of the torsion spring abut against the door cover 2 and the housing 1 respectively.

[0058] The fit between the pivot and the shaft hole ensures smooth rotation of the door cover 2. A slight gap can be set between them to reduce friction, or grease can be added to further improve rotational performance. The torsion spring, as an elastic element, is twisted and stores force during the closing process of the door cover 2. When the door cover 2 is unlocked, the latching part 21 disengages from the fastening plate 31, and the torsion spring releases its elastic potential energy, generating a torque that causes the door cover 2 to rotate around the pivot, automatically opening the door cover 2 at a certain angle for easy opening by the user. The elastic force of the torsion spring can be adjusted according to the weight of the door cover 2 and the required opening angle, ensuring that the door cover 2 can open automatically without causing collision damage due to excessive opening force. This structural design improves the ease of use of the door cover 2, especially suitable for scenarios requiring one-handed operation.

[0059] This utility model also proposes a microcomputer, which includes a door cover structure 100. The specific structure of the door cover structure 100 is as described in the above embodiments. Since this microcomputer adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, and will not be described in detail here. As a portable electronic device, a microcomputer usually needs to be equipped with structures such as a battery compartment and an expansion interface compartment. The application of the door cover structure 100 can provide reliable opening and closing control for these structures. In the microcomputer, the shell 1 of the door cover structure 100 can be integrally formed with the main shell 1 of the microcomputer or fixedly connected by screws. The door cover 2 is used to cover the opening of the battery compartment or the interface compartment, protecting the interface from dust and moisture intrusion. By adopting the above-mentioned door cover structure 100, the user of the microcomputer can unlock the door cover 2 by a simple pressing operation. With the automatic spring-loaded function, the door cover 2 can be easily opened for battery replacement or interface use; when closing, simply press the door cover 2 to the latching position to lock it, making the operation convenient and efficient. The compact design of the cover structure 100 does not increase the size of the microcomputer, and its stable mechanical fit ensures long-term reliability, improving the overall usability and user experience of the microcomputer.
