Description

Technical Field

[0001] This application relates to the field of housing assembly technology, specifically to a cover plate disassembly and assembly assembly and an industrial control computer. Background Technology

[0002] Electronic devices generally consist of a housing and a circuit structure installed within the housing. The housing serves as a mounting platform for the internal circuit structure and also provides effective protection for it. The housing is typically composed of multiple separate parts assembled together. The circuit structure is installed inside first, and then the various parts are assembled and secured together.

[0003] Taking industrial control computers as an example, their outer casing usually includes a chassis and a cover. One end of the chassis is open to allow for the disassembly and assembly of the circuit structure, and the cover closes to the opening to cover and protect the internal circuit structure.

[0004] In existing industrial PCs, the cover is mostly fixed to the opening of the chassis by multiple screws. This makes it time-consuming to remove and install the cover during the assembly of the industrial PC and the disassembly and maintenance of the internal components, which affects the overall efficiency. Utility Model Content

[0005] In view of the above problems, this application provides a cover plate disassembly and assembly assembly that enables convenient disassembly and assembly of the cover plate.

[0006] According to one aspect of the embodiments of this application, a cover plate disassembly and assembly is provided, applied to a chassis with a detachable cover plate. The cover plate disassembly and assembly includes: a base for mounting on the chassis; a lifting mechanism including: a lifting member, vertically and vertically connected to the base, for descending under the pressure of the cover plate during installation and rising to lift the cover plate during disassembly; a locking member, movably disposed on the base, for moving to a locked state when the lifting member descends to the designated position and to an unlocked state when the cover plate is disassembled; a snap-fit ​​mechanism, movably connected to the base, for detachably snap-fitting with a snap fastener on the cover plate; and a transmission mechanism connected between the lifting member and the snap-fit ​​mechanism, for driving the snap-fit ​​mechanism to move and snap-fit ​​with the snap fastener when the lifting member descends, thereby fixing the cover plate to the chassis. The transmission mechanism is also used to drive the snap-fit ​​mechanism to move and separate from the snap fastener when the lifting member rises, thereby lifting the cover plate.

[0007] In one alternative embodiment, the base includes a button seat, a lifting member is fastened to the button seat and moves vertically in cooperation with the outer side wall of the button seat, a lifting elastic member is connected between the lifting member and the button seat, the lifting elastic member provides an upward elastic force to the lifting member; the button seat has an internal mounting cavity, an opening is provided on the side wall of the button seat, and a locking part is provided at the position opposite to the opening when the lifting member is lowered to the position; the locking member includes a locking rod rotatably disposed in the mounting cavity, one end of the locking rod has a locking protrusion, the locking rod is used to rotate when the lifting member is lowered to the position so that the locking protrusion passes through the opening and engages with the locking part, thereby restricting the rise of the lifting member; the button seat is also provided with a button, the button cooperates with the end of the locking rod opposite to the locking protrusion, the button is used to drive the locking rod to rotate when pressed so that the locking protrusion separates from the locking part, thereby releasing the restriction on the rise of the lifting member.

[0008] In one alternative embodiment, the locking mechanism is slidably connected to the base; the outer wall of the lifting member extends along the lifting direction and is provided with a drive rack; the transmission mechanism includes a gear set and a transmission slider; the transmission slider is connected to the locking mechanism; the transmission slider is provided with a driven rack; the gear set is driven between the drive rack and the driven rack; the lifting member is used to drive the locking mechanism to slide through the gear set and the transmission slider during lifting, so that the locking mechanism can engage or disengage from the buckle.

[0009] In one alternative embodiment, the base further includes a sliding seat disposed on at least one side of the button seat. A snap-fit ​​mechanism is slidably connected to the sliding seat along a first direction, and a transmission slider is slidably connected to the sliding seat along a second direction, wherein the first direction is perpendicular to the second direction. The transmission slider and the snap-fit ​​mechanism are engaged by inclined friction, and a first elastic element is connected between the side of the snap-fit ​​mechanism away from the transmission slider and the sliding seat. The first elastic element is used to provide a spring force to the snap-fit ​​mechanism to slide toward the transmission slider. The snap-fit ​​mechanism is used to slide along the first direction under the action of the transmission slider or the first elastic element to snap or separate from the buckle.

[0010] In one alternative embodiment, the button base is provided with sliding seats and locking mechanisms on both sides along the first direction, and the transmission slider is respectively engaged with the locking mechanisms on both sides through inclined friction.

[0011] In one alternative embodiment, the locking mechanism includes a locking slider and a locking block, which are arranged opposite to each other along a first direction and are both slidably connected to a sliding seat along the first direction. A first elastic element is connected between the side of the locking block away from the locking slider and the sliding seat, and a second elastic element is connected between the locking block and the locking slider. The transmission slider and the side of the locking slider away from the second elastic element are engaged by inclined friction. The lifting member is used to drive the locking slider toward the locking block via a gear set and a transmission slider when it descends under the pressure of the cover plate, so as to compress the first... The two elastic elements have a force greater than that of the first elastic element, causing the locking block to slide away from the locking slider and engage with the latch. The lifting element is also used to drive the transmission slider to slide through the gear set when the cover is raised, thereby releasing the space on the side of the locking slider away from the locking block. This releases the force of the second elastic element and pushes the locking slider away from the locking block. When the force of the second elastic element is less than that of the first elastic element, the first elastic element pushes the locking block to slide towards the locking slider, thereby separating the locking block from the latch.

[0012] In one alternative embodiment, the top of the latch is provided with a ramp surface. The latch is used to slide toward the latch slider by squeezing the second elastic element and stretching the first elastic element during the pressing of the cover plate and when the ramp surface is subjected to the pressure of the latch, so that the latch can continue to descend. The latch is also used to slide away from the latch slider under the elastic recovery of the first and second elastic elements when the cover plate is pressed into place, so as to engage with the latch.

[0013] In one alternative embodiment, the cover plate removal assembly also includes a switching mechanism movably connected to the base for a separable limiting connection with the transmission mechanism to lock or unlock the lifting mechanism and the locking mechanism.

[0014] In one alternative embodiment, the cover plate assembly is symmetrically mounted on opposite side walls of the chassis along a second direction; the base includes a switch base for mounting on the side wall of the chassis along a first direction; the switching mechanism includes a rotating block, a switch lever, and two sets of limiting members, each limiting member including a connecting rod, a sliding rod, and a limiting rod; the rotating block is rotatably mounted on the switch base, and the switch lever is slidably mounted on the outside of the chassis, penetrating the chassis wall and movably connected to the rotating block, the switch lever driving the rotating block to rotate during sliding; two sliding rods are slidably mounted on both sides of the switch base along the second direction, in each In the middle, the connecting rod is hinged between one end of the sliding rod and the rotating block; two limiting rods are respectively set on the two opposite sides of the two sliding rods, and both limiting rods are slidable along the first direction. In each side, the limiting rod and the sliding rod are driven together, and a limiting part is provided on the transmission mechanism at the position opposite to the limiting rod; the switch block is used to make the two sliding rods slide opposite to each other or towards each other along the second direction when the rotating block is driven to rotate. In each side, the sliding rod makes the limiting rod slide towards or away from the transmission mechanism along the first direction, thereby making the limiting rod engage or disengage with the limiting part to lock or unlock the movement restriction of the transmission mechanism.

[0015] According to another aspect of the embodiments of this application, an industrial control computer is provided, including a chassis, a cover plate, and a cover plate disassembly assembly as described above. The cover plate disassembly assembly is disposed on the chassis, and the cover plate is provided with a buckle. The cover plate is detachably connected to the chassis by the cooperation of the buckle and the cover plate disassembly assembly.

[0016] In the cover plate assembly provided in this embodiment, the base is responsible for the overall installation and fixation on the chassis. The base is equipped with a lifting mechanism and a snap-fit ​​mechanism that are interconnected by a transmission mechanism. The snap-fit ​​mechanism is responsible for snapping with the snaps on the cover plate, realizing the quick assembly and fixation of the cover plate on the chassis. When removing the cover plate, the lifting mechanism rises and lifts the cover plate while the transmission mechanism drives the snap-fit ​​mechanism to move, thereby releasing the snap-fit ​​mechanism from the snaps on the cover plate. This allows the cover plate and chassis to not only be automatically disassembled, but the cover plate is also automatically lifted by the lifting mechanism, making it easy for technicians to remove the cover plate and perform subsequent hardware-related operations in the chassis, achieving easy and convenient disassembly and assembly of the cover plate.

[0041] In the description of the embodiments of this application, technical terms such as "first" and "second" are used only to distinguish different objects and should not be construed as indicating or implying relative importance or implicitly specifying the number, specific order, or primary and secondary relationship of the indicated technical features. In the description of the embodiments of this application, "multiple" means two or more, unless otherwise explicitly defined.

[0042] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0043] In the description of the embodiments in this application, the term "and / or" is merely a description of the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent three cases: A exists, A and B exist simultaneously, and B exists.

Therefore, they should not be construed as limitations on the embodiments of this application.

[0046] In the description of the embodiments of this application, unless otherwise expressly specified and limited, technical terms such as "installation," "connection," "joining," and "fixing" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. For those skilled in the art, the specific meaning of the above terms in the embodiments of this application can be understood according to the specific circumstances.

[0047] The casing of electronic devices such as computers and servers is usually composed of a chassis and a cover. The internal circuit structure is installed inside the chassis, and the cover is detachably fixed to the chassis with screws.

[0048] Taking industrial PCs as an example, they are a special type of computer used in industrial environments. In order to better protect the internal circuit structure, industrial PCs mostly adopt a fanless casing cooling method, that is, heat dissipation fins that can increase the heat dissipation area are set on the cover plate. The internal heat is dissipated to the outside through the chassis and cover plate. The cover plate is usually connected to the chassis by multiple screws at the edge.

[0049] Whether it's an industrial control computer or other types of electronic equipment, when hardware upgrades or maintenance are needed, the cover plate must be removed before the corresponding operations can be performed. However, the screw connection method not only requires a suitable screwdriver, but also takes a long time to disassemble, which makes the disassembly and assembly of the cover plate complicated and time-consuming, affecting the efficiency of hardware upgrades or maintenance.

[0050] To address this issue, this application proposes a cover plate assembly / disassembly component. A base is responsible for the overall installation and fixation on the chassis. The base is equipped with a lifting mechanism and a locking mechanism connected to each other via a transmission mechanism. The locking mechanism engages with the clips on the cover plate, enabling quick assembly and fixation of the cover plate on the chassis. When disassembling the cover plate, the lifting mechanism rises and lifts the cover plate while the transmission mechanism drives the locking mechanism to disengage from the clips on the cover plate. This allows the cover plate to be automatically disassembled from the chassis, and the lifting mechanism automatically lifts the cover plate, facilitating easy removal of the cover plate by technicians for subsequent hardware operations within the chassis. This achieves easy and convenient cover plate assembly / disassembly.

[0051] This application provides cover plate disassembly and assembly components, including but not limited to those used in industrial control computers, computers, servers and other electronic devices, as well as other devices whose housings are assembled from multiple parts. The following description and accompanying drawings use an industrial control computer as an example, which does not constitute a limitation on the specific application areas of the cover plate disassembly and assembly components.

[0052] According to one aspect of the embodiments of this application, an industrial control computer is provided; please refer to the details below. Figure 1 The figure shows the perspective structure of the industrial computer. As shown, the industrial computer 500 includes a cover plate assembly 100, a chassis 200, and a cover plate 300. To facilitate the structural display of the cover plate assembly 100 located inside the chassis 200, the chassis 200 is represented in a transparent form with gray double-dotted lines. The structures shown in the other figures below are similarly represented in the same way.

[0053] The cover plate 300 is provided with a latch 310, which is specifically located on the side of the cover plate 300 facing the chassis 200. Figure 1The buckle 310 and the cover plate 300 are shown in an exploded state. In the specific embodiment shown in the figure, the buckle 310 has a connecting hole 311. The buckle 310 can be installed on the cover plate 300 by rivets, threaded fasteners, etc. Of course, the buckle 310 can also be an integral structure with the cover plate 300. The cover plate 300 can be provided with heat dissipation fins 320 as shown in the figure, or it can be a conventional flat plate.

[0054] The cover plate removal assembly 100 is mounted on the chassis 200, and the cover plate 300 is detachably connected to the chassis 200 via a latch 310 that engages with the cover plate removal assembly 100. The specific engagement method between the latch 310 and the cover plate removal assembly 100 will be explained in detail below, and will not be elaborated here.

[0055] According to another aspect of the embodiments of this application, a cover plate disassembly and assembly 100 is provided that can be applied to the industrial control computer 500 provided in the above embodiments. Please... Figure 1 Based on further integration Figures 2 to 5 The figure shows the structure of different parts of the cover plate disassembly and assembly 100. The cover plate disassembly and assembly 100 includes a base 110, a lifting mechanism 120, a transmission mechanism 130, and a locking mechanism 140.

[0056] like Figure 1 As shown, the base 110 is used to be installed on the chassis 200 as a carrier for the installation and fixation of other mechanisms. The base 110 can adopt the shell structure shown in the figure, or it can adopt the structure of bracket, mounting plate, mounting block, etc. The specific form is not limited here.

[0057] like Figure 2 and Figure 3 As shown, the lifting mechanism 120 includes a lifting component 121 and a locking component 122. It should be noted that... Figure 3 In the specific structure shown, the lifting member 121 is represented by a transparent gray double-dotted line, and the locking member 122 is covered inside the lifting member 121. The lifting member 121 is vertically and vertically connected to the base 110 along the z-axis, and the locking member 122 is movably connected to the base 110.

[0058] Please combine again Figure 1When installing the cover plate 300, first place the cover plate 300 downwards along the z-axis. The bottom of the cover plate 300 will abut against the top of the lifting member 121, and the lifting member 121 will descend under the pressure of the cover plate 300. After the lifting member 121 has descended into place, that is, after the cover plate 300 is installed, the locking member 122 moves to the state of locking the lifting member 121, preventing it from moving up or down, ensuring that the cover plate 300 will not be subjected to the force of the lifting member 121 after assembly. Conversely, when removing the cover plate 300, operate the locking member 122 to the state of unlocking the lifting member 121, so that the lifting member 121 rises and lifts the cover plate 300.

[0059] Regarding the 120 lifting mechanism, in Figure 2 and Figure 3 In the illustrated embodiment, the base 110 includes a button seat 111. A lifting member 121 is fastened to the button seat 111 and engages with the outer wall of the button seat 111 in a lifting-sliding manner. For example, it can be engaged with a slider and a slide rail, a slider and a slide rail, a roller and a slide rail, etc., and the specific method is not limited here. A lifting elastic member 123 is connected between the lifting member 121 and the button seat 111. The lifting elastic member 123 is used to provide an upward elastic force to the lifting member 121 in the direction shown by the z-axis. The lifting elastic member 123 can be a compression spring as shown in the figure, or it can be a spring sheet, an elastic soft rubber block, etc.

[0060] The button base 111 has an installation cavity 1111 inside, and the side wall of the button base 111 has an opening 1112. When the lifting member 121 is lowered into place, a locking part 1211 is provided at the position opposite to the opening 1112. In the figure, the locking part 1211 is a bayonet, but in other embodiments it can also be a slot, a protrusion, etc.

[0061] The locking member 122 includes a locking rod 1222 rotatably disposed within the mounting cavity 1111 via a first rotating shaft 1221, and one end of the locking rod 1222 has a locking protrusion 12221. In the specific embodiment shown in the figure, in order to improve the stability of limiting the lifting member 121, there are two locking rods 1222 arranged in a mirror symmetrical manner. In other embodiments, more or only one locking rod may be provided, and the principle is the same.

[0062] Regarding the locking of the lifting component 121, such as Figure 4aAs shown in the locked state from a top-down view, when the lifting member 121 is lowered into place, that is, when the cover plate 300 is installed in place, the right locking rod 1222 rotates clockwise relative to its first pivot 1221, while the left locking rod 1222 rotates counterclockwise relative to its first pivot 1221 (the movement relationship of the right locking rod 1222 is only described below, while the left locking rod 1222 moves in the opposite direction). The locking protrusion 12221 passes through the opening 1112 and engages with the locking part 1211, restricting the lifting member 121 from rising and ensuring that the cover plate 300 is not subjected to the force of the lifting member 121 after installation.

[0063] Please continue reading. Figure 4a The button base 111 is also provided with a button 124. The button 124 is engaged with the end of the locking rod 1222 that is away from the locking protrusion 12221. Specifically, it can be engaged by the inclined friction shown in the figure, or it can be engaged by the coarse hole with a thin shaft. The specific engagement method is not limited here, as long as it is ensured that when the button 124 is pressed, the button 124 can drive the right locking rod 1222 to rotate counterclockwise.

[0064] Regarding the unlocking of the lifting component 121, specifically, as follows: Figure 4b As shown in the unlocked state from a top-down view, when button 124 is pressed inward, button 124 causes the right locking lever 1222 to rotate counterclockwise, and the locking protrusion 12221 separates from the locking part 1211. That is, the locking protrusion 12221 and the locking part 1211 are no longer engaged, and the upward restriction of the lifting member 121 is released. Thus, under the elastic force of the lifting elastic member 123, the lifting member 121 will drive the cover plate 300 to rise to lift it up.

[0065] Furthermore, such as Figure 4b As shown, a locking elastic element 125 can be provided between the locking lever 1222 and the button seat 111. The locking elastic element 125 is used to provide a clockwise rotational reset force to the right locking lever 1222 so that when the lifting member 121 is lowered into place and the button 124 is not pressed, the locking protrusion 12221 remains engaged with the locking part 1211, thereby ensuring that the cover plate 300 and the chassis 200 remain in a mutually assembled and fixed state.

[0066] In the embodiment shown in the attached drawings, a push-button switch is used to release the locking of the lifting member 121, which makes it easier to remove the cover plate 300 from the chassis 200. Specifically, when removing the cover plate 300, no auxiliary tools are required. After pressing the button 124, the cover plate 300 can automatically pop up under the action of the lifting member 121. Then, the cover plate 300 can be easily removed to replace or maintain the internal circuit structure.

[0067] The above describes the specific structure and working principle of the lifting mechanism 120 provided in the corresponding embodiment. However, the specific implementation of the lifting mechanism 120 is not limited to this. For example, the lifting member 121 may be a spring pin that can elastically extend and retract relative to the base 110, and the locking member 122 may be a pin that can slide relative to the base 110, or a baffle that can rotate relative to the base 110. In the unlocked state, the spring pin extends relative to the base 110. When the cover plate 300 is placed, the cover plate 300 presses down on the spring pin to retract it. After it is pressed into place, the pin or baffle can be moved to a locked state where it connects with and limits the spring pin through an electric drive, an elastic reset member, or manual operation, ensuring that the cover plate 300 is not subjected to the force of the spring pin after assembly. When it is necessary to remove the cover plate 300, the pin or baffle is operated in the opposite direction to release the extension and retraction restriction on the spring pin. The spring pin automatically extends and lifts the cover plate 300 to facilitate subsequent removal and removal of the cover plate 300.

[0068] For the transmission mechanism 130 and the locking mechanism 140, please refer to... Figures 2 to 6 In the specific embodiment shown in the figure, the snap-fit ​​mechanism 140 is slidably connected to the base 110. For example... Figure 2 As shown, a drive rack 1212 extends along the lifting direction (i.e., the direction shown by the z-axis in the figure) on the outer wall of the lifting member 121, and the transmission mechanism 130 includes a gear set 131 and a transmission slider 132. Figures 2 to 6 As shown, the transmission slider 132 is connected to the snap-fit ​​mechanism 140. The transmission slider 132 is provided with a driven rack 1321, and the gear set 131 is connected between the driving rack 1212 and the driven rack 1321.

[0069] like Figure 1 and Figure 6 As shown, the base 110 also includes a slide seat 112, which is disposed on at least one side of the button seat 111. Figure 5 and Figure 6 As shown, the locking mechanism 140 is slidably connected to the sliding seat 112 along a first direction (the direction shown by the x-axis in the figure), and the transmission slider 132 is slidably connected to the sliding seat 112 along a second direction (the direction shown by the y-axis in the figure). The transmission slider 132 and the locking mechanism 140 are engaged by inclined friction, and a first elastic element 143 is connected between the side of the locking mechanism 140 away from the transmission slider 132 and the sliding seat 112. The first elastic element 143 is used to provide a spring force to the locking mechanism 140 to slide towards the transmission slider 132.

[0070] like Figure 5 and Figure 6 As shown, the latching mechanism 140 includes a locking slider 141 ( Figure 5(In perspective view) and the latch block 142, the latch slider 141 and the latch block 142 are arranged opposite each other along the x-axis and are slidably connected to the sliding seat 112 along the x-axis.

[0071] The side of the locking block 142 away from the locking slider 141 is connected to the sliding seat 112 by a first elastic element 143. The locking block 142 and the locking slider 141 are connected by a second elastic element 144. The transmission slider 132 and the side of the locking slider 141 away from the second elastic element 144 are in frictional engagement through inclined surfaces (first inclined surface 1322 and second inclined surface 1411 in the figure).

[0072] like Figure 2 and Figure 3 As shown, the gear set 131 can use helical gear transmission to convert the lifting movement of the lifting member 121 along the z-axis into the sliding of the transmission slider 132 along the y-axis. It can also be configured with gears of different diameters meshing together to achieve speed reduction and torque increase. In other embodiments, worm gears, lead screw modules, or other mechanisms can also be used to convert the lifting movement of the lifting member 121 into the sliding of the transmission slider 132 in different directions.

[0073] Please combine Figures 1 to 6 When the cover plate 300 is installed, the lifting member 121 is lowered along the z-axis by the pressure of the cover plate 300. The driving rack 1212 drives the transmission slider 132 through the gear set 131 and the driven rack 1321. Figure 5 As shown in the diagram, the slider slides downwards, causing the transmission slider 132 to slide towards the locking slider 141 along the y-axis. Under the compression and friction between the first inclined surface 1322 and the second inclined surface 1411, the locking slider 141 slides towards the locking block 142 along the x-axis. The second elastic element 144 is compressed, and its elastic force gradually increases. When the elastic force of the second elastic element 144 is greater than the elastic force of the first elastic element 143, the locking block 142 slides away from the locking slider 141 along the x-axis under the action of the elastic force of the second elastic element 144, and finally engages with the latch 310 on the cover plate 300. Figure 6 and Figure 7 The status shown.

[0074] Furthermore, to ensure that the cover plate 300 can still be easily installed on the chassis 200 despite the influence of manufacturing and assembly tolerances, such as... Figure 6As shown, the top of the locking block 142 can be provided with a ramp surface 1421. During the pressing and assembly of the cover plate 300, if the lifting component 121 fails to promptly drive the locking block 142 to avoid the latch 310 via the intermediate transmission component, the ramp surface 1421 will be subjected to the pressure of the latch 310. At this time, the locking block 142 will squeeze the second elastic element 144 and stretch the first elastic element 143 to slide towards the locking slider 141, thereby avoiding the latch 310 and allowing the latch 310 to continue to descend. When the latch 310 descends to its position, the ramp surface 1421 is no longer subjected to pressure. At this time, the first elastic element 143 and the second elastic element 144 will restore their deformation to keep the elastic force on the locking block 142 balanced, that is, the locking block 142 will slide away from the locking slider 141, thereby forming a latch between the locking block 142 and the latch 310, and the cover plate 300 is fixed to the chassis 200.

[0075] The above are the solutions corresponding to the embodiments shown in the accompanying drawings. In other embodiments, the locking mechanism 140 may only consist of a locking block 142 and a first elastic member 143. The first elastic member 143 is also disposed between the locking block 142 and the sliding seat 112, providing a sliding unlocking force to the locking block 142. Furthermore, the locking block 142 directly engages with the transmission slider 132 through inclined friction. Figure 5 From the perspective of the transmission slider 132, when it slides backward along the y-axis, the friction between the inclined surfaces drives the locking block 142 to slide to the right along the x-axis and engage with the buckle 310. When the transmission slider 132 slides forward along the y-axis, the locking block 142 slides to the left along the x-axis under the elastic force of the first elastic element 143 and disengages from the buckle 310.

[0076] Considering that a single-point snap-fit ​​makes it difficult to stably assemble and fix the cover plate 300 onto the chassis 200, therefore, if Figure 1 As shown, sliding seats 112 and locking mechanisms 140 can be provided on both sides of the button base 111 along the x-axis. The transmission slider 132 is respectively engaged with the locking mechanisms 140 on both sides through inclined friction. With this configuration, the cover plate 300 can be locked and fixed at multiple points by the latches 310 and the locking mechanisms 140, and multiple latches 310 can be unlocked simultaneously with just one button 124. This improves the assembly stability of the cover plate 300 while ensuring convenient operation during disassembly.

[0077] exist Figure 1 In the specific embodiment shown, although only one locking mechanism 140 is provided on each side of the button base 111, the transmission slider 132 slides along the y-axis, while the locking mechanism 140 slides along the x-axis after the transmission slider 132 slides through the inclined friction engagement. Therefore, even if multiple locking mechanisms 140 are provided on each side of the button base 111, the same transmission slider 132 can simultaneously drive each locking mechanism 140 to slide.

[0078] Furthermore, such as Figure 1 As shown, a button base 111 can be provided on each of the opposite sides of the chassis 200, and a snap-fit ​​mechanism 140 is provided on both sides of each button base 111, so that the cover plate 300 and the chassis 200 form a multi-point snap-fit ​​at the opposite sides and near the end points, which makes the assembly stable and reliable. Moreover, the multiple snap-fit ​​points on each side are simultaneously controlled by a button 124 to unlock, and the cover plate 300 is easy to disassemble.

[0079] Furthermore, without employing a beveled friction fit, the overall structure of the transmission slider 132 and the locking mechanism 140 can be further simplified. Specifically, the locking mechanism 140 only includes a locking block 142, and the sliding directions of both the transmission slider 132 and the locking block 142 are set to the x-axis direction, with the transmission slider 132 and the locking block 142 fixedly connected. For example, it can be... Figure 2 and 3 Based on the illustrated embodiment, the helical gear transmission in the gear set 131 is eliminated, and the extension direction of the driven rack 1321 on the transmission slider 132 is adaptively adjusted so that the original sliding direction of the transmission slider 132 along the y-axis is changed to along the x-axis. With this setting, when the lifting member 121 descends under the pressure of the cover plate 300, Figure 5 From this perspective, the transmission slider 132 and the locking block 142 will slide together to the right along the x-axis, and the locking block 142 will engage with the buckle 310. When the cover plate 300 is removed, the lifting member 121 rises, causing the transmission slider 132 and the locking block 142 to slide together to the left along the x-axis. The locking block 142 releases its engagement with the buckle 310, and the cover plate 300 can be lifted and removed normally.

[0080] To prevent accidental activation of the unlocking component of the lifting mechanism 120, which could cause the cover plate 300 to pop up unexpectedly and potentially damage the equipment, this application also incorporates anti-accidental activation designs for both the lifting mechanism 120 and the locking mechanism 140. Please refer again for details. Figure 1 As shown in the figure, the cover plate disassembly assembly 100 also includes a switching mechanism 150, which is movably connected to the base 110. The switching mechanism 150 is used to be detachably limited connected to the transmission mechanism 130 to lock or unlock the lifting mechanism 120 and the locking mechanism 140.

[0081] Specifically, the switching mechanism 150 can be detachably limited to the transmission mechanism 130 by means of a sliding pin, a rotating latch, or other mechanisms.

[0082] After the cover plate 300 is installed, the switch mechanism 150 is operated to the state of being limited to the transmission mechanism 130. At this time, if the unlocking part on the lifting mechanism 120 is accidentally touched, the lifting mechanism 120 and the locking mechanism 140 will not move due to the limitation of the movement of the transmission mechanism 130 by the switch mechanism 150, thereby avoiding the situation where the cover plate 300 is accidentally opened.

[0083] When the switch mechanism 150 is accidentally triggered, causing the transmission mechanism 130 to unlock, the cover 300 will not open accidentally because the unlocking component on the lifting mechanism 120 is not triggered. Therefore, when the cover 300 needs to be removed, the switch mechanism 150 must be unlocked first, and then the unlocking component on the lifting mechanism 120 must be triggered. The probability of accidentally triggering both the switch mechanism 150 and the unlocking component on the lifting mechanism 120 simultaneously is extremely low, thus effectively preventing the cover 300 from being accidentally opened.

[0084] against Figure 1 The embodiment shown uses a multi-point snap-fit ​​method at the four corners to assemble the cover plate 300. This application proposes a specific implementation of a switching mechanism 150, firstly as follows: Figure 1 As shown, the cover plate assembly 100 is symmetrically arranged on the two opposite side walls of the chassis 200 along the direction shown by the y-axis.

[0085] Please combine further Figures 8 to 10 , Figure 8 The diagram shows a perspective view of the switch mechanism 150 on the chassis 200. Figure 9 and Figure 10 The structure of a portion of the switching mechanism 150 is shown.

[0086] like Figure 8 As shown, the base 110 includes a switch holder 113 for mounting on a side wall of the chassis 200 along the x-axis. The switching mechanism 150 includes a rotating block 151 and a switch lever 152 (in... Figure 8 The perspective view is used to represent the solid state; for the solid state, please refer to [reference needed]. Figure 1 It also includes two sets of limiting components 153, each of which includes a connecting rod 1531, a sliding rod 1532, and a limiting rod 1533.

[0087] like Figure 8 and Figure 9 As shown, the rotating block 151 is rotatably mounted on the switch base 113 relative to the second rotating shaft 1511, and the switch lever 152 is slidably mounted on the outside of the chassis 200. The switch lever 152 passes through the wall of the chassis 200 and is movably connected to the rotating block 151. The switch lever 152 is used to drive the rotating block 151 to rotate when sliding.

[0088] Specifically, the sliding direction of the switch block 152 can be the direction shown by the y-axis, and the switch block 152 and the rotating block 151 can be... Figure 9 At point A, a coarse hole and a fine shaft are used to move together so that when the switch block 152 slides left and right along the y-axis, it drives the rotating block 151 to rotate in the counterclockwise or clockwise direction.

[0089] like Figure 9 As shown, two sliding rods 1532 are slidably disposed on both sides of the switch base 113 along the direction shown by the y-axis, and on each side, a connecting rod 1531 is hinged between one end of the sliding rod 1532 and the rotating block 151.

[0090] like Figure 8 and Figure 10 As shown, two limiting rods 1533 are respectively disposed on opposite sides of the two sliding rods 1532, and both limiting rods 1533 are slidably disposed along the x-axis. On each side, the limiting rod 1533 is driven by the sliding rod 1532, and a limiting part 133 is provided on the transmission mechanism 130 at a position opposite to the limiting rod 1533. The limiting part 133 may be, for example, a snap-fit ​​groove, a snap-fit ​​hole, or a snap-fit ​​block.

[0091] When limiting and locking the transmission mechanism 130, Figure 9 From the perspective shown, moving the switch block 152 to the right causes the rotating block 151 to rotate clockwise, and the two sliding rods 1532 slide away from each other under the transmission of their respective connecting rods 1531. Figure 10 From the perspective of the sliding rod 1532, the left end of the sliding rod 1532 and the limiting rod 1533 can be engaged by the inclined surface friction. Under the squeezing action of the inclined surface, the limiting rod 1533 slides upward and the top end extends into the limiting part 133 on the transmission mechanism 130. At this time, the top end of the limiting rod 1533 and the limiting part 133 form a jamming, and the transmission mechanism 130 is restricted and cannot move further.

[0092] like Figure 10 As shown, the base 110 may further include a mounting seat 114 disposed on the side wall of the chassis 200. A limiting rod 1533 is slidably disposed on the mounting seat 114. A limiting elastic element 1534 is connected between the limiting rod 1533 and the mounting seat 114. The limiting elastic element 1534 provides a spring force to the limiting rod 1533 to slide towards the sliding rod 1532, thereby... Figure 9 After toggling switch 152 to the left from the perspective of the viewpoint, Figure 10 The sliding rod 1532 slides to the right and releases the frictional engagement with the limiting rod 1533. Under the elastic force of the limiting elastic element 1534, the limiting rod 1533 slides downward. The end of the limiting rod 1533 away from the sliding rod 1532 separates from the limiting part 133 on the transmission mechanism 130, thus releasing the movement restriction on the transmission mechanism 130.

[0093] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and not to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this application.
