Description

Technical Field

[0001] This utility model relates to the field of CNC machining, and in particular to a cover connection structure and an engraving machine. Background Technology

[0002] In existing engraving machines, the cover and housing are connected by a hinge. During the development of this application, the inventors discovered that users, unaware of when the cover reaches its maximum opening angle, typically open it with full force, continuing to exert force even at this point. This results in significant stress on the connection structure between the cover and housing (and even greater stress due to the typically large size of the cover), leading to a high damage rate and severely impacting the lifespan of the connection. Utility Model Content

[0003] This utility model provides a cover connection structure and an engraving machine to solve at least one of the above-mentioned technical problems.

[0004] This utility model embodiment provides a cover connection structure for connecting the cover and housing of an engraving machine. The cover connection structure includes: a cover connecting part, a connecting shaft, a housing connecting part, and a feedback mechanism. A first end of the cover connecting part is connected to the cover, a second end of the cover connecting part is fixedly connected to a first end of the connecting shaft, and a second end of the connecting shaft is fixedly connected to the housing. The first end and the second end of the connecting shaft are rotatable relative to each other. The feedback mechanism is disposed between the second end of the cover connecting part and the housing connecting part. When the cover is opened to a preset position, the feedback mechanism emits a prompt sound.

[0005] In some embodiments, the feedback mechanism includes a movable feedback component and a fixed feedback component. The movable feedback component is disposed at the second end of the cover connection portion, and the fixed feedback component is disposed on the housing connection portion. When the cover is opened to a preset position, the movable feedback component and the fixed feedback component interact to emit a prompt sound.

[0006] In some embodiments, the active feedback component is a rigid component and the fixed feedback component is an elastic component. When the cover is opened to a preset position, the active feedback component moves the fixed feedback component to generate vibration and emit a prompt sound.

[0007] In some embodiments, the rigid member is fixed to the second end of the cover connection portion, and one end of the elastic member is fixed to the housing connection portion.

[0008] In some embodiments, the housing connection is a crossbeam of the housing, the crossbeam includes a top wall and a side wall, a notch is provided on the crossbeam, the notch extends from the top wall to the side wall, and the side wall has a bottom edge of the notch corresponding to the position of the notch.

[0009] In some embodiments, the rigid component is an L-shaped paddle, and the elastic component is a T-shaped elastic sheet.

[0010] In some embodiments, the active feedback component is an elastic component and the fixed feedback component is a rigid component. When the cover is opened to a preset position, the fixed feedback component moves the active feedback component to generate vibration and emit a prompt sound.

[0011] In some embodiments, both the active feedback component and the fixed feedback component are elastic components. When the cover is opened to a preset position, the fixed feedback component and the active feedback component vibrate against each other to produce a prompt sound.

[0012] In some embodiments, the first end of the hood connector is connected to the lower surface of the top plate of the hood, and the second end of the hood connector is located below the plane of the top plate of the hood.

[0013] In some embodiments, the connecting shaft is a damping shaft.

Detailed Implementation

[0018] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model. It should be noted that, unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other.

[0019] It should also be noted that, in this document, the terms "comprising" or "including" include not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Unless otherwise specified, an element defined by the phrase "comprising..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes that element.

[0020] like Figure 1 The diagram shown is a structural schematic of one embodiment of the engraving machine provided in this application. Figure 2 As shown Figure 1 A magnified view of part A in the middle. (See image below.) Figure 3 As shown Figure 1 A schematic diagram of the exploded structure of section A in the middle.

[0021] like Figure 1 As shown, the engraving machine includes a cover 1 and a housing 2. A crossbeam 21 is provided at the top of the housing 2, and the cover 1 is connected to the crossbeam of the housing 2 through a cover connecting structure. The cover 1 can be opened and closed relative to the housing around the cover connecting structure. The space enclosed by the cover 1 and the housing 2 can be used to install the three-axis moving mechanism, work platform, engraving machine spindle, etc. required by the engraving machine, but this application does not limit this.

[0022] like Figure 2 and Figure 3 As shown, the hood connection mechanism 3 includes a hood connection part 31, a connecting shaft 32, and a feedback mechanism 33. The feedback mechanism 33 includes a movable feedback component 331 and a fixed feedback component 332.

[0023] The first end of the cover connecting part 31 is connected to the lower surface of the cover 1, and the second end of the cover connecting part 31 is fixedly connected to the first end of the connecting shaft 32. The second end of the connecting shaft 32 is fixedly connected to the housing. The connecting shaft 32 can be a damping shaft.

[0024] The second end of the cover connecting part 31 is provided with a screw hole, and the first end of the connecting shaft 32 is fixedly connected to the second end of the cover connecting part 31 by screws.

[0025] The crossbeam 21 of the housing 2 is provided with screw holes, and the second end of the connecting shaft 32 is fixedly installed by screws engaging with the screw holes on the crossbeam 21.

[0026] Continue to refer to Figure 2 and Figure 3 The active feedback component 331 is an L-shaped lever (rigid component), and the fixed feedback component 332 is a T-shaped elastic sheet (elastic component). A screw hole is provided on one side wall of the L-shaped lever for fixing with a screw to the second end of the cover connection part 31. In this embodiment, the L-shaped lever can be fixed together with the second end of the connecting shaft 32 with a screw to the second end of the cover connection part 31.

[0027] It should be noted that the activity feedback component 331 can also be a flat lever or a lever of other shapes, and this application does not limit this. For example, when the activity feedback component 331 is a flat lever, the flat lever can be fixedly installed on the side wall of the second end of the cover connection portion 31. In addition, the flat lever can also be configured to be integrally formed with the side wall of the second end of the cover connection portion 31, and this application does not limit this.

[0028] The horizontal portion of the T-shaped elastic sheet has a screw hole, and a corresponding screw hole is provided on the crossbeam 21 of the housing 2. The horizontal portion of the T-shaped elastic sheet is fixedly mounted on the crossbeam 21 of the housing 2 by screws. A recess 211 is provided on the crossbeam 21 opposite to the T-shaped elastic sheet to accommodate the vertical portion of the T-shaped elastic sheet, allowing the T-shaped elastic sheet to vibrate up and down within this recess 211. For example, the T-shaped elastic sheet can be made of 60Mn spring steel.

[0029] In this embodiment, the L-shaped paddle is a rigid component, and the T-shaped elastic piece is an elastic component. When the cover 1 rotates to a preset position around the connecting shaft 32 via the cover connecting part 31 (for example, rotating 90 degrees from the closed state, the corresponding L-shaped paddle also rotates 90 degrees), the L-shaped paddle actuates the longitudinal part of the T-shaped elastic piece, causing the T-shaped elastic piece to vibrate and emit a beeping sound.

[0030] like Figure 4 As shown Figure 2 A structural schematic diagram from another perspective. In this embodiment, the crossbeam 21 includes a top wall 214 and a side wall 215. A notch 211 is provided on the crossbeam 21 at the position where the T-shaped spring is installed. The horizontal part of the T-shaped spring is fixedly installed on the top wall 212, and the vertical part of the T-shaped spring is located in the notch 211, so that the vertical part of the T-shaped spring can vibrate in the space of the notch 211. Further, the notch 211 extends from the top wall 214 to the side wall 215, and the side wall 215 has a bottom edge 2111 of the notch corresponding to the position of the notch 211.

[0031] In this embodiment, during the opening of the cover 1, when the cover connecting part 31 rotates around the connecting shaft 32 to a preset position (for example, rotating 90 degrees from the closed state, the corresponding L-shaped lever also rotates 90 degrees), the L-shaped lever actuates the longitudinal part of the T-shaped elastic piece, causing the T-shaped elastic piece to vibrate and emit a warning sound. If the cover 1 continues to be opened, the L-shaped lever will abut against the bottom edge 2111 of the notch, achieving mechanical limiting of the cover, thereby avoiding physical damage caused by excessive opening of the cover to the cover or other components on the housing due to compression.

[0032] This invention employs a simple lever-type mechanical structure. Utilizing the rotational motion of the flip cover, when the door or cover reaches a predetermined position, the lever is activated, generating vibration and producing a sound. This solves the problem of the lack of clear and effective indication when the cover's opening and closing is limited. It effectively increases the safety of equipment use and maintenance.

[0033] In some modified embodiments, the active feedback component 331 can be configured as an elastic component and the fixed feedback component 332 as a rigid component. When the cover 1 is opened to a preset position (for example, rotated 90 degrees from the closed state, the corresponding fixed feedback component also rotates 90 degrees), the fixed feedback component moves the active feedback component to generate vibration and emit a prompt sound.

[0034] In some modified embodiments, both the active feedback component 331 and the fixed feedback component 332 can be configured as elastic components. When the cover 1 is opened to a preset position (for example, rotated 90 degrees from the closed state, the corresponding fixed feedback component also rotates 90 degrees), the fixed feedback component and the active feedback component move against each other to generate vibration and emit a prompt sound.

[0035] In some modified embodiments, the first end of the cover connecting part 31 is connected to the lower surface of the top plate of the cover 1, and the second end of the cover connecting part 31 is located below the plane of the top plate of the cover (when the cover is in a fully closed state). The cover connecting part 31 in this embodiment allows the engraving machine in actual application to further provide a crossbeam 21 cover plate flush with the upper surface of the cover 1 above the crossbeam 21, so that when the cover 1 is in a fully closed state, the top of the entire engraving machine is completely flat.

[0036] like Figure 5-7 The diagram shown is a cross-sectional schematic of three different embodiments of the hood connection portion 31 in this application. Among them, Figure 5 The hood connection 31 shown is U-shaped. Figure 6 The cover connection 31 shown is U-shaped. Figure 7 The cover connection 31 shown is V-shaped. Figure 5-7 The left end of the hood connector shown is the first end of the hood connector, and the right end is the second end of the hood connector. It should be noted that the above is only an example, and this application does not limit the specific shape of the hood connector.

[0037] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended 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 of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this application.
