Description

Technical Field

[0001] This invention relates to the field of household sewing equipment technology, and in particular to a multi-functional household sewing machine that integrates convenient storage, on-demand lighting, and automatic reset support for the worktable after folding. Background Technology

[0002] Most existing household sewing machines are standalone units, typically requiring a separate storage box or external cover for dust protection, making them inconvenient to move and carry. In low-light home environments, insufficient lighting in the needle area can lead to difficulties in threading and alignment, affecting sewing efficiency and safety. Furthermore, portable or small sewing machines, in order to reduce size, often lack sufficient support for the worktable, resulting in poor stability during sewing. The worktable's unfolding and storage are also not convenient, impacting the user experience. Inconvenient needle installation, removal, and adjustment further increase the barrier to entry for home users.

[0003] Therefore, it is necessary to provide a multi-functional household sewing machine that can achieve portable storage, protection, and immediate use upon opening the lid, and also has functions such as opening-lid lighting, stable support for the workbench, and automatic reset storage. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides a multi-functional household sewing machine, aiming to solve at least one of the following technical problems: 1) The sewing machine lacks an integrated storage and portability structure, making it inconvenient to handle and protect; 2) Insufficient lighting in the needle area affects operation in a home setting; 3) The workbench lacks stability and ease of storage and repositioning; 4) Optionally, the needle is inconvenient to install, remove, and adjust in height.

[0005] To address the above problems, the present invention provides a multi-functional household sewing machine, comprising a storage box and a sewing machine body disposed within the storage box: The storage box includes a lower shell and an upper shell, which are rotatably connected by a first hinge. An opening and closing limiting support mechanism is provided between the lower shell and the upper shell of the box. The opening and closing limiting support mechanism is used to limit the opening angle of the upper shell relative to the lower shell and to provide support for the upper shell in the open state. The storage box is equipped with a locking mechanism, which is used to lock the lower shell and the upper shell of the box when the box is closed. The storage box is equipped with a handle on the outside. A lighting device is provided on the inner side of the upper shell of the box; The sewing machine body is provided with a worktable, which is rotatably connected to a folding support. A reset elastic element is provided between the worktable and the folding support. The folding support has an unfolded position and a retracted position. The reset elastic element is used to reset the folding support to the retracted position after the external force is released.

[0006] Furthermore, the opening and closing limiting support mechanism includes a damping support member, which is used to provide damping buffer during the opening or closing of the upper shell of the housing.

[0007] Furthermore, the locking mechanism is a latch-type locking structure.

[0008] Furthermore, the lighting device is electrically connected to the linkage triggering mechanism, which is configured to activate the lighting device when the upper shell of the housing is opened and deactivate the lighting device when the upper shell of the housing is closed.

[0009] Furthermore, the lighting device is electrically connected to a control switch, which is used to manually control the lighting device to turn on and off.

[0010] Furthermore, the sewing machine body can be detachably installed inside the lower shell of the housing.

[0011] Furthermore, the sewing machine body includes a drive motor and a handwheel, and the drive motor is connected to the handwheel via a transmission assembly.

[0012] Furthermore, a thread feeder is provided on the top of the sewing machine head for mounting the spool and feeding the thread.

[0013] Furthermore, the sewing machine body is provided with a needle clamp assembly and a sewing needle. The needle clamp assembly is provided with a locking hole, and a locking fastener is provided in the locking hole. The locking fastener is used to clamp and fix the sewing needle.

[0014] Furthermore, the needle clip assembly is also provided with a positioning fastener, which is used to position and limit the needle. The needle clip assembly is provided with a mounting hole or mounting groove for inserting the needle, so as to adjust the effective extension of the needle by changing the insertion depth of the needle.

[0015] Compared with the prior art, the present invention has at least the following beneficial effects: 1) This invention integrates the sewing machine body and the openable and closable storage box into a single structure, which can achieve dust protection, impact protection and transport without the need for external storage equipment; after the box is opened, it directly forms the upper working space and the lower supporting base, realizing "open and use", which significantly improves the convenience of use for home users and the overall product quality. 2) By integrating a lighting device inside the upper shell of the cabinet and supporting automatic linkage triggering or manual switch control, the light can reach the needle area and workbench area directly, effectively improving the common problem of insufficient illumination in the home environment, improving the accuracy and safety of threading, needle positioning and observation of stitches, and reducing the risk of misoperation and visual fatigue. 3) The worktable and the folding support are connected by a rotating mechanism, and the automatic retraction and reset are achieved after the external force is released through the reset elastic element, which avoids the risk of increased volume or transportation damage caused by users forgetting to retract the support after sewing; the support is stable when unfolded for sewing, and compact and reliable when folded, taking into account both working stability and compact storage. 4) The needle clip assembly features clamping holes and fasteners, allowing for quick release and locking of the needle. It also supports adjusting the effective extension of the needle tip by changing the insertion depth, improving maintenance efficiency and applicability. This allows home users to perform needle replacement and height adjustment operations without professional skills. Attached Figure Description

[0018] The technical solution of the present invention will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0019] like Figures 1 to 7 As shown in the figure, an embodiment of the present invention provides a multi-functional household sewing machine, including a storage box and a sewing machine body disposed within the storage box. This product combines a "stored and portable state" with an "open and working state," enabling the sewing machine to achieve closed protection, easy transport, and immediate use in a home setting.

[0020] The storage box includes a lower shell 1 and an upper shell 2. The lower shell 1 forms an installation / storage space for the sewing machine body. The upper shell 2 cooperates with the lower shell 1 to close and form a protective cover. When open, it forms an upper enclosure / shielding structure, thus providing some shielding and space for sewing operations. The sewing machine body includes a base 8, a machine head shell 9, and an internal frame 13. A worktable area (worktable plate 19) is formed at the base 8 to support the fabric.

[0021] like Figure 1 , Figure 2 As shown, the lower shell 1 and the upper shell 2 of the box are rotatably connected by a first hinge 3. The first hinge 3 can be a hinge, a pivot hinge, or other structures that can achieve a rotatable connection, so that the upper shell 2 can rotate relative to the lower shell 1 around the hinge axis to realize the conversion of the box from a closed state to an open state.

[0022] In the closed state, the upper shell 2 and the lower shell 1 of the box cooperate to form a relatively closed internal space, which is used to protect the sewing machine body from dust, collisions and transportation. In the open state, the upper shell 2 of the box flips to the open position, thereby exposing the working area of ​​the sewing machine body, and the user can directly perform operations such as threading, changing needles and sewing.

[0023] like Figures 1-2 As shown, an opening and closing limiting support mechanism 4 is provided between the lower shell 1 and the upper shell 2 of the box. The opening and closing limiting support mechanism 4 is used to limit the opening angle of the upper shell 2 relative to the lower shell 1 of the box and to provide support for the upper shell 2 in the open state, so as to prevent the upper shell 2 from falling back due to gravity or external disturbances, thereby improving operational safety and stability.

[0024] In this embodiment, the opening and closing limiting support mechanism 4 can be implemented in any of the following ways: Damping support method: The opening and closing limit support mechanism 4 includes a damping support. The two ends of the damping support are connected to the lower shell 1 and the upper shell 2 of the box respectively. It provides damping buffer during the opening or closing of the upper shell 2, so that the opening / closing of the upper shell is smoother and the support force is maintained in the open position. Limiting hinge method: A hinge with a limiting structure is used so that the upper shell 2 of the box is limited and stopped when it is opened to a set angle; Folding support rod method: Foldable support rod is provided. When the support rod is unfolded, it provides support for the upper shell 2 of the box and limits the opening angle. When stored, it can be folded and fits into the inside of the shell. Gas spring support method: using gas springs to provide support and cushioning.

[0025] All of the above structures can achieve the function of "limiting and supporting", and the specific structural form is not limited to the attached diagram.

[0026] like Figure 1 As shown, the storage box is equipped with a locking mechanism 5, which is used to lock the lower shell 1 and the upper shell 2 of the box when the box is closed, preventing the box from being accidentally opened during carrying and transportation. The locking mechanism 5 can be a latch-type locking structure, a flexible snap-locking structure, or other equivalent locking methods.

[0027] A handle 6 is provided on the outside of the box, which is used by the user to carry and transport the closed storage box. In some embodiments, the handle 6 may be a flip-up or embedded structure to reduce outward protrusion and reduce the risk of bumps and knocks during transportation when closed.

[0028] like Figure 2 As shown, an illumination device 7 is provided on the inner side of the upper shell 2 of the housing. The illumination device 7 is used to illuminate the operating area of ​​the sewing machine body when the housing is open, especially to supplement the needle area and the worktable 19 area, thereby improving visibility in low-light environments at home.

[0029] Lighting device 7 can be an LED light strip, LED light chip module, ring light, etc.; its control method can include, but is not limited to: Linkage trigger control: The lighting device 7 is electrically connected to the linkage trigger mechanism, which can be a mechanical contact switch, magnetic switch, or micro switch, etc. The trigger is activated when the upper shell 2 of the enclosure is opened and deactivated when the upper shell 2 of the enclosure is closed, so as to realize automatic lighting / extinguishing. Manual switch control: The lighting device 7 is electrically connected to the control switch, which can be used to manually control the lighting and extinguishing of the lights.

[0030] In some embodiments, the illumination device 7 can be directed toward the front area of ​​the needle clip assembly 14 and the worktable 19, thereby making threading, alignment and observation of the stitches more intuitive.

[0031] like Figures 2-4As shown, the sewing machine body is housed within the lower casing 1 of the housing. The sewing machine body includes a base 8, a head housing 9, and a frame 13 housed inside the head housing 9. The frame 13 serves as a load-bearing skeleton, housing the drive motor 10, transmission components 11, handwheel 12, and needle bar mechanism, thread take-up mechanism, fabric feeding mechanism, and bobbin thread supply mechanism related to sewing operations.

[0032] Regarding the installation method, the present invention can be implemented in one of the following ways: Detachable installation: The sewing machine body can be detachably installed inside the lower shell 1 of the housing, for example, by screw connection, buckle positioning, slide rail plug-in or other detachable connection methods, so that users can take out the sewing machine body for separate use or maintenance; Fixed installation: The sewing machine body is fixedly installed inside the lower shell 1 of the case, so that the lower shell 1 of the case can directly serve as the working support base of the sewing machine body after the case is opened, improving the convenience of "open and use".

[0033] The machine head housing 9 is used to cover the frame 13 and internal mechanisms and provide appearance and protection; the base 8 is used to support the worktable 19 and related components and form a fabric support platform.

[0034] like Figure 4 As shown, the drive motor 10 is mounted on the frame 13. The drive motor 10 is connected to the handwheel 12 via the transmission assembly 11, thereby transmitting the motor power to the spindle end, driving the needle bar to reciprocate and realize the sewing operation. The handwheel 12 can also be manually rotated for needle position calibration, threading assistance, or maintenance operations.

[0035] The transmission component 11 can be a belt-pulley drive, a gear drive, or other equivalent transmission structure. Belt drives can reduce vibration and noise and provide a certain buffering effect; gear drives can improve transmission rigidity and reduce the risk of slippage. The above transmission methods can be selected according to product size, cost, and noise requirements.

[0036] It should be noted that conventional mechanisms related to sewing (such as the thread guide structure, tension adjustment structure, thread take-up lever, presser foot mechanism, fabric feeding mechanism, bobbin / bottom thread supply mechanism, etc.) can be implemented using existing mature solutions, and the specific forms of these conventional mechanisms do not constitute a limitation of this invention. The core of this invention lies in the combined design of an integrated storage box, opening lighting, and an automatic reset support structure for the worktable after folding.

[0037] like Figure 3 and Figure 4As shown, a wire feeding rod 22 is provided at the top of the machine head for mounting the spool and feeding the upper wire. In some embodiments, the wire feeding rod 22 may be a detachable or foldable structure to reduce its height and internal space occupied when stored; a limit cap or baffle may be provided at the top of the wire feeding rod 22 to prevent the spool from jumping off during the wire feeding process.

[0038] In some embodiments, the wire feeding rod 22 can work with the wire guide to form a wire guide path, so as to guide the wire to the tension adjustment part and the needle area, thereby improving the stability of the wire routing.

[0039] like Figures 5-6 As shown, the sewing machine body is provided with a needle clamp assembly 14 and a sewing needle 15. The needle clamp assembly 14 is used to install, position, and clamp the sewing needle 15.

[0040] The needle clip assembly 14 is provided with a mounting hole or mounting slot for inserting the sewing needle 15. The user can adjust the effective extension of the sewing needle 15 by changing the insertion depth of the sewing needle 15 to adapt to different fabric thicknesses, different sewing conditions or different stitch requirements.

[0041] The needle clip assembly 14 is provided with a locking hole 16, and a locking fastener 18 is provided in the locking hole 16. The locking fastener 18 is used to clamp and fix the needle 15. Furthermore, the needle clip assembly 14 is also provided with a positioning fastener 17, which is used to position and limit the needle 15 (e.g., limit the angle of the needle handle or lateral sway), thereby improving the stability and repeatability of the needle installation. The needle 15 can be released by loosening the locking fastener 18, realizing quick assembly and disassembly; tightening the locking fastener 18 can complete the locking and fixing; the positioning fastener 17 can be used to assist positioning or further improve the clamping effect.

[0042] like Figure 7 As shown, the sewing machine body has a worktable 19, which supports the fabric and forms a sewing platform. To balance sewing stability and portability, the worktable 19 is rotatably connected to a folding support 20, which has an unfolded position and a stowed position. When the folding support 20 is in the unfolded position, it provides support for the worktable 19, improving the rigidity and stability of the worktable and reducing problems such as skipped stitches and unstable stitching caused by shaking during the sewing process. When the folding support 20 is in the storage position, it fits or retracts to the storage area below / to the side of the worktable 19, thereby reducing the overall size and making it easier to put the sewing machine body into the storage space formed by the lower shell 1 and the upper shell 2 of the box.

[0043] A reset elastic element 21 is provided between the worktable 19 and the folding support 20. The reset elastic element 21 applies a reset force to the folding support 20 toward the storage position, so that the folding support 20 can automatically return to the storage position after the external force is released. This reduces the number of storage steps, lowers the risk of damage during transportation caused by users forgetting to put it back, and improves the portability experience. The reset elastic element 21 can be a torsion spring, compression spring, or tension spring, etc., and the specific form is not limited.

[0044] A typical usage process of this embodiment can be as follows: (1) The user releases the locking mechanism 5 and flips the upper shell 2 of the box to the open state through the first hinge 3. The opening and closing limit support mechanism 4 restricts and supports the upper shell 2. (2) The lighting device 7 is automatically lit under the action of the linkage triggering mechanism or manually lit by the control switch; (3) The user places the fabric on the workbench 19 and, if necessary, flips the folding support 20 to the unfolded position to support the workbench; (4) Install the bobbin of thread using the thread feeding rod 22 and guide the thread routing. If necessary, calibrate the needle position using the handwheel 12. (5) After sewing is finished, the user can release the folding support 20, reset the elastic element 21 so that it automatically returns to the storage position, then close the upper shell 2 of the box and lock it through the locking mechanism 5. The handle 6 is used for carrying and transporting.

[0045] Other optional implementation methods Without departing from the concept of this invention, the following improvements can be made: (1) In addition to damping support components, the opening and closing limit support mechanism 4 can also use limit hinges, folding struts or gas spring support components; (2) The locking mechanism 5 may adopt a snap-on or elastic buckle structure; (3) The wire rod 22 can be configured as a detachable, foldable or telescopic structure to further optimize the storage space; (4) The lighting device 7 can be installed on the front, middle or both sides of the upper shell 2 of the housing to obtain a better illumination angle; (5) The installation position and force direction of the reset elastic element 21 can be adjusted according to the flipping axis of the flipping support 20, as long as the effect of "resetting towards the storage position after the external force is released" can be achieved.

[0046] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
