Description

Technical Field

[0001] This utility model relates to the field of keyboard shell technology, specifically to a keyboard shell structure that is easy to assemble. Background Technology

[0002] The keyboard is the primary input device used by computers and other electronic devices to input data and control systems. As a computer input device, the keyboard undertakes multiple tasks such as inputting text, numbers, and commands, and provides convenient control methods through shortcut keys and special function keys. One of the main functions of the keyboard casing is to protect the internal electronic components such as circuit boards, keys, and connectors. It prevents dust, dirt, moisture, and other external substances from entering the interior, maintaining the keyboard's normal operation and extending its lifespan.

[0003] Chinese Patent Publication No. CN212208214U discloses a keyboard housing structure for easy keyboard installation. The structure includes a keyboard housing, characterized by: a notch at the bottom; a base plate slidably connected inside the keyboard housing; a spring contact fixedly connected to the lower end of the base plate; a retaining strip fixedly connected to the surface of the spring contact; a cable winding frame fixedly connected to the lower end of the base plate; the cable winding frame and the base plate being an integral structure; a circuit board slidably connected inside the keyboard housing; a rubber pad adhered to the lower end of the circuit board; keys mounted on the upper end of the circuit board; a support column fixedly connected to the inner side of the keyboard housing; and a connecting column fixedly connected to the lower end of the base plate, with a first limiting groove and a second limiting groove on the surface of the connecting column. This invention provides a convenient keyboard housing structure with advantages such as easy keyboard assembly, stable keyboard placement, and easy cable management for carrying.

[0004] The aforementioned patent mentions that when assembling the keyboard casing, the keyboard casing needs to be placed on top of the base plate, and the base plate is pressed down. This causes the retaining strip to be squeezed by the keyboard casing, driving the spring to deform and allowing the retaining strip to engage with the slot, thus assembling the keyboard casing. During this process, there is a lack of a guiding structure between the retaining strip and the slot. When the base plate moves the retaining strip through the spring, the retaining strip and the slot are prone to misalignment. At the same time, because it is difficult to control the deformation of the spring, when the base plate and the keyboard casing are connected, the spring causes the retaining strip to squeeze against the keyboard casing, making it easy for the base plate and the keyboard casing to jam, affecting the smoothness of keyboard casing assembly. Therefore, we propose a keyboard casing structure that is easy to assemble. Utility Model Content

[0005] To address the aforementioned issues, a keyboard shell structure that facilitates assembly is provided. By controlling the first limiting mechanism through a winding mechanism to determine whether mechanical force is applied to the shell body, the technical problem of jamming between the base plate and the keyboard shell, which affects the smoothness of keyboard shell assembly, is solved.

[0006] To address the problems of existing technologies, this utility model provides a keyboard shell structure that is easy to assemble, including a shell body, a support plate for housing internal keyboard components, and a base plate. The base plate is disposed on the lower side of the shell body, and the upper side of the base plate is connected to the support plate. The keyboard shell structure also includes a first limiting mechanism and a winding mechanism. The first limiting mechanism is disposed between the base plate and the support plate, and is used to restrict the shell body and the base plate together. The winding mechanism is disposed on the base plate, and the working end of the winding mechanism is connected to the first limiting mechanism. The winding mechanism is used to control whether the first limiting mechanism limits the shell body and the base plate.

[0026] To further understand the features, technical means, and specific objectives and functions achieved by this utility model, the following detailed description of this utility model is provided in conjunction with the accompanying drawings and specific embodiments.

[0027] See Figures 1-3 As shown, a keyboard shell structure that is easy to assemble includes a shell body 1, a support plate 101 for housing internal keyboard components, and a base plate 102. The base plate 102 is disposed on the lower side of the shell body 1, and the upper side of the base plate 102 is connected to the support plate 101. The keyboard shell structure also includes a first limiting mechanism and a winding mechanism. The first limiting mechanism is disposed between the base plate 102 and the support plate 101, and is used to restrict the shell body 1 and the base plate 102 together. The winding mechanism is disposed on the base plate 102, and the working end of the winding mechanism is connected to the first limiting mechanism. The winding mechanism is used to control whether the first limiting mechanism limits the shell body 1 and the base plate 102.

[0028] Specifically, during the keyboard casing assembly process, the worker first operates the winding mechanism to tighten the control on the first limiting mechanism. Then, the casing body 1 is placed on the outside of the base plate, so that the first limiting mechanism is located inside the casing body 1. At this point, the winding mechanism is controlled to release the control on the first limiting mechanism, causing the casing body 1 and the base plate 102 to quickly achieve mutual positioning and thus tightly join together.

[0029] During the docking process between the outer shell body 1 and the base plate 102, the winding mechanism should control the first limiting mechanism to ensure that it does not apply mechanical force to the outer shell body 1. After the outer shell body 1 and the base plate 102 are docked, the winding mechanism controls the first limiting mechanism to apply mechanical force to the outer shell body 1, thereby ensuring that the outer shell body 1 and the base plate 102 are not prone to jamming during the assembly process, which may adversely affect the assembly process.

[0030] See Figure 1~ Figure 3 As shown, the first limiting mechanism includes a guide component and a snap-fit ​​component; the guide component is disposed between the outer shell body 1 and the base plate 102, and the guide component is used to assist the outer shell body 1 and the base plate 102 in positioning and docking; the snap-fit ​​component is disposed between the outer shell body 1 and the guide component, and the snap-fit ​​component is used to restrict the outer shell body 1 and the base plate 102 together.

[0031] Specifically, during the assembly of the outer shell body 1 and the base plate 102, the base plate 102 can be docked with the outer shell body 1 using a guide assembly. The installation of the guide assembly ensures that the base plate 102 and the outer shell body 1 are accurately positioned and docked, effectively preventing the base plate 102 from shifting inside the outer shell body 1, thereby avoiding jamming.

[0032] See Figure 1~ Figure 3 , Figure 5 , 7 and Figure 8 As shown, the guide assembly includes a docking groove 2 and a docking plate 201; the docking groove 2 is opened inside the outer shell body 1; the docking plate 201 is connected to the upper side of the base plate 102, and the docking plate 201 is slidably docked with the docking groove 2.

[0033] Specifically, the docking groove 2 and the docking plate 201 are mutually compatible. When the base plate 102 docks with the outer shell 1, the base plate 102 drives the docking plate 201 to slide and dock with the docking groove 2 first. Due to the compatibility between the docking groove 2 and the docking plate 201, the docking plate 201 can effectively suppress the occurrence of displacement within the docking groove 2, thereby ensuring that the base plate 102 and the outer shell 1 can stably complete the docking process.

[0034] See Figure 1~ Figure 3 , Figure 5 , 7 and Figure 8 As shown, the snap-fit ​​assembly includes a snap-fit ​​slot 202, a snap-fit ​​plate 203, and a first elastic reset member 204; the snap-fit ​​slot 202 is opened on the side of the outer shell body 1 near the docking slot 2; the snap-fit ​​plate 203 is rotatably connected to the docking plate 201; one end of the elastic reset member is connected to one side of the snap-fit ​​plate 203, and the other end of the elastic reset member is connected to the docking plate 201.

[0035] Specifically, the slot 202 and the plate 203 engage in a snap-fit ​​connection. After the plate 201 and the slot 202 are engaged, the plate 203 and the slot 202 engage in a snap-fit ​​connection under the action of the first elastic reset member 204. The first elastic reset member 204 can maintain the continuous engagement state of the plate 203 and the slot 202, thereby ensuring that the outer shell body 1 and the base plate 102 are stably connected and mutually limit each other.

[0036] See Figure 4 , Figure 6 and Figure 7 As shown, the winding mechanism includes a support rod 3, a connecting rope 301, a winding drum 302, and a connecting rod 303; the side of the clamping plate 203 away from the docking plate 201 is connected to the support rod 3; the connecting rope 301 is disposed between the two support rods 3, and one end of the connecting rope 301 is connected to the clamping plate 203; the winding drum 302 is disposed on the base plate 102, and the winding drum 302 is connected to the end of the connecting rope 301 away from the clamping plate 203; the upper end of the connecting rod 303 is connected to the winding drum 302, and the lower end of the connecting rod 303 slides through the interior of the base plate 102.

[0037] Specifically, during the assembly of the outer shell 1 and the base plate 102: First, the connecting rod 303 is rotated, which drives the winding drum 302 to rotate. The winding drum 302 winds the connecting rope 301 to its inner side. As the connecting rope 301 is wound, tension is generated, pulling the clamping plate 203 to rotate. As the clamping plate 203 rotates, it simultaneously drives the support rod 3 to rotate until the support rod 3 is in contact with the base plate. At this time, the first elastic reset member 204 is stretched due to the force, and the clamping plate 203 and the mating plate 201 are perpendicular.

[0038] Next, while keeping the winding drum 302 wound up the connecting rope 301, the base plate 102 is docked with the outer casing 1. Since the connecting rope 301 is in the wound state, the clamping plate 203 will not come into contact with the outer casing 1.

[0039] After the docking plate 201 and the docking groove 2 are docked, the connecting rod 303 is rotated in the opposite direction. At this time, the winding drum 302 loosens the connecting rope 301, and the guide wheel installed near the docking plate 201 guides the winding and unwinding process of the connecting rope 301. As the connecting rope 301 loosens, the first elastic reset member 204 no longer bears tension and returns to its initial position. During the process of the first elastic reset member 204 returning to its original position, it drives the locking plate 203 to return to its original position simultaneously. At the same time, the locking plate 203 and the locking groove 202 complete the locking and docking action, finally realizing the mutual limiting connection between the outer shell body 1 and the base plate 102.

[0040] See Figure 4 and Figure 6 As shown, the connecting rod 303 includes a second limiting mechanism, which further includes a plug 4, a slot 401, and a second elastic reset member 402. The plug 4 is connected to the outer side of the connecting rod 303. The slot 401 is opened on the side of the base plate 102 near the plug 4, and the slot 401 is used to mate with the plug 4. One end of the second elastic reset member 402 is connected to the base plate, and the other end of the second elastic reset member 402 is rotatably connected to the connecting rod 303.

[0041] Specifically, slot 401 has a rectangular cross-section and is adapted to insert block 4. During the winding process of the take-up drum 302 winding the connecting rope 301, the connecting rod 303 is pushed upward, causing the second elastic reset member 402 to retract. Since a gap is reserved between the support plate and the base plate to meet the displacement requirements of the connecting rod 303, the connecting rod 303 can drive the insert block 4 to disengage from slot 401. At this time, rotating the connecting rod 303 drives the take-up drum 302 to perform the winding action of the connecting rope 301.

[0042] When the winding drum 302 needs to maintain the winding state of the connecting rope 301, the connecting rod 303 is pulled down, causing the connecting rod 303 to drive the insert 4 to re-engage with the slot 401. At this time, the second elastic reset member 402 applies a force to the insert 4 through the connecting rod 303, creating a compressive force between the insert 4 and the slot 401 to ensure that the insert 4 and the slot 401 remain in an engaged state. This restricts the rotation of the connecting rod 303 by the insert 4, ensuring that the winding drum 302 stably maintains the winding state.

[0043] See Figures 4-7 As shown, the first elastic reset member 204 and the second elastic reset member 402 are made of spring material.

[0044] Specifically, the spring material provides a stable and adjustable elastic restoring force. During the docking process between the locking plate 203 and the locking slot 202, the first elastic reset member 204 can quickly and accurately push the locking plate 203 to complete the engagement action with the locking slot 202. When subjected to a certain degree of external impact or interference, the elastic deformation of the spring can absorb energy, preventing hard collisions between the locking plate 203 and the locking slot 202 that could cause wear or damage, and ensuring that the stable limiting connection between the outer shell 1 and the base plate 102 is not affected.

[0045] See Figure 6 As shown, the connecting rope 301 is made of polyester rope.

[0046] Specifically, the polyester rope has high tensile strength, allowing the connecting rope 301 to withstand significant tension without easily breaking or detaching. Furthermore, the polyester rope exhibits good abrasion resistance; when the connecting rope 301 rubs against surrounding components during operation, it effectively resists this frictional wear, extending its service life, reducing the frequency of replacement due to frequent friction, and lowering maintenance costs.

[0047] Working principle: During the assembly of the outer shell body 1 and the base plate 102, the guide component functions to prevent the base plate 102 from shifting and avoid jamming between it and the outer shell body 1. Simultaneously, the winding mechanism controls the clamping plate 203, causing it to rotate. Furthermore, the second limiting mechanism ensures that the clamping plate 203 remains perpendicular to the docking plate 201. During the sliding docking process between the docking plate 201 and the docking groove 2, the clamping plate 203 will not come into contact with the outer shell body 1, thus ensuring the smoothness of the shell structure assembly process.

[0048] The above embodiments only illustrate one or more implementations of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of this utility model. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the appended claims.
