The equipment uses a motor-driven needle bar mechanism to complete continuous sewing actions, and works in conjunction with a feeding mechanism, presser foot mechanism, and positioning fixtures to achieve stable transport and precise sewing of the workpiece.

[0003] As shown in the reference case "A sewing machine for processing electric vehicle seat covers" (publication number CN219385561U), by setting up the cooperation of the drive component and the clamping component, the sewing of electric vehicle seat covers can be automated. This helps to reduce the workload of operators, improve the efficiency and standardization of electric vehicle seat cover sewing, and reduce the production cost of electric vehicle seat covers, thereby improving the production efficiency of electric vehicle seat covers.

[0004] However, in the actual production of products such as electric vehicle seat covers, due to differences in varieties, structures, or decorative effects, it is often necessary to replace sewing needles of different models, adjust the stitch length, or change the needle type structure. When changing the needle position, existing sewing equipment usually requires disassembling multiple parts such as the needle bar, presser foot, and feed teeth in sequence, and readjusting the stitch length and feed synchronization mechanism, which is a cumbersome and time-consuming process. Utility Model Content

[0005] Therefore, it is necessary to address the issue that in the production of products such as electric vehicle seat covers, different types of sewing needles and stitch length adjustments are often required for different varieties, structures, or decorative effects. Existing equipment requires the sequential disassembly of parts such as the needle bar, presser foot, and feed teeth, as well as the readjustment of the synchronization mechanism, when changing needle positions. This process is cumbersome and time-consuming. Therefore, an easy-to-operate automatic sewing device for electric vehicle seat covers should be provided.

[0006] An easy-to-operate automatic sewing device for electric vehicle seat covers includes: a processing base, a support frame fixedly installed on one side of the processing base, and a sewing head provided on one side of the support frame; a modular sewing mechanism, a telescopic modular sewing mechanism for replacing the sewing head is provided on the outside of the processing base; wherein, the modular sewing mechanism includes a sewing table provided on the top of the processing base, a modular assembly is provided between the sewing head and the support frame, and a tensioning assembly is provided on the outside of the sewing table.

[0007] The module assembly includes a power receiving plate fixedly installed on one side of the support frame. The bottom of the power receiving plate is fixedly installed on the mounting tube. One side of the suture head extends into the interior of the mounting tube. Guide tubes are fixedly installed on both sides of the mounting tube, and limit rods are slidably installed on one side of each of the two guide tubes. The adjacent sides of the two limit rods extend into the interior of the mounting tube and abut against the surface of the suture head.

[0008] The surface of the suture head has two limiting grooves, which are located at one end of two limiting rods, and the two limiting rods are slidably connected to the two limiting grooves.

[0009] The adjacent ends of the two limiting rods are both set in an arc shape, and the shapes of the two limiting grooves are adapted to the corresponding limiting rods.

[0010] A spring is installed through the surface of the limiting rod, and the other end of the spring is fixedly connected to the guide tube.

[0011] Pull rings are fixedly installed at the ends of the two limiting rods that are far apart, and the two pull rings are located on both sides of the mounting tube.

[0012] The tensioning assembly includes movable frames disposed on both sides of the suture table. A support rod is fixedly installed on one side of each of the two movable frames. Two abutting tubes are disposed on the surface of the support rods. The same abutting plate is rotatably installed on the outer side of the two abutting tubes. The abutting plate abuts against the suture table.

[0013] A torsion spring is fixedly installed between the inside of the clamping tube and the surface of the support rod, and the cross-section of the clamping plate is set to an isosceles rectangle.

[0014] A first resistance slide rail is fixedly installed on the surface of the processing seat, and a second resistance slide rail is fixedly installed at the output end of the first resistance slide rail.

[0016] Beneficial effects

[0017] 1. The modular component allows for quick replacement of the sewing head without disassembling the needle bar, presser foot, feed teeth, etc., enabling flexible switching between different sewing needle models, stitch lengths, or needle types. This significantly reduces changeover time and improves production line flexibility and efficiency. Its precise positioning and locking structure ensures stable installation of the sewing head, preventing skipped stitches, thread breaks, or decreased accuracy caused by positional misalignment. The tensioning component continuously tightens the seat cover during sewing, keeping the fabric smooth and wrinkle-free, ensuring even stitches and good appearance quality.

[0018] 2. With the cooperation of the support rod and the clamping tube, the clamping plate can be flexibly adjusted along both sides of the sewing table.

[0027] 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.

[0028] The following is combined Figures 1-5 This invention describes an easy-to-operate automatic sewing device for electric vehicle seat covers.

[0029] In one embodiment, an easy-to-operate automatic sewing device for electric vehicle seat covers includes: a processing base 100, a support frame 200 fixedly mounted on one side of the processing base 100, and a sewing head 210 disposed on one side of the support frame 200; a modular sewing mechanism 300, a telescopic modular sewing mechanism 300 for replacing the sewing head 210 disposed on the outside of the processing base 100; wherein, the modular sewing mechanism 300 includes a sewing table 310 disposed on the top of the processing base 100, a modular assembly 320 disposed between the sewing head 210 and the support frame 200, and a tensioning assembly 330 disposed on the outside of the sewing table 310.

[0030] In this embodiment, the modular component 320 allows for the rapid replacement of the sewing head 210 without disassembling multiple parts such as the needle bar, presser foot, and feed teeth. This enables flexible switching between different sewing needle models, stitch lengths, or needle types, significantly reducing changeover time, avoiding production delays caused by prolonged downtime, and significantly improving the flexibility and adaptability of the production line. Simultaneously, the modular component 320 employs a precise positioning and locking structure, ensuring stable installation of the replaced sewing head 210 and support frame 200. This prevents skipped stitches, thread breaks, or decreased sewing accuracy due to positional misalignment during sewing. The tensioning component 330 continuously and stably tensions the electric vehicle seat cover during sewing, keeping the fabric or leather flat and wrinkle-free under the needle position, contributing to even stitch distribution and improving the overall appearance quality of the sewing.

[0031] It should be noted that existing automatic sewing equipment typically includes basic components such as a processing base 100, a support frame 200, a sewing head 210, a needle bar mechanism, a presser foot mechanism, a feeding mechanism, a drive motor, and control components. These components work together to complete actions such as feeding, positioning, and sewing. The module component 320 is in a static or standby state when the sewing head 210 is being replaced. The tensioning component 330 only acts on the surface of the workpiece during the sewing process and will not interfere with the coordinated operation of core moving parts such as the needle bar and the feeding teeth, thus ensuring the stability and safety of the equipment.

[0032] like Figure 2 , Figure 3 and Figure 4 As shown, the module assembly 320 includes a power receiving plate 321 fixedly installed on one side of the support frame 200. The bottom of the power receiving plate 321 is fixedly installed on the mounting tube 322. One side of the suture head 210 extends into the interior of the mounting tube 322. Guide tubes 323 are fixedly installed on both sides of the mounting tube 322. Limiting rods 324 are slidably installed on one side of each of the two guide tubes 323. The adjacent sides of the two limiting rods 324 extend into the interior of the mounting tube 322 and abut against the surface of the suture head 210.

[0033] In this embodiment, the junction plate 321 enables quick electrical connection and disconnection when replacing the suture head 210, avoiding the cumbersome wiring steps in the traditional replacement process. The guide tube 323 provides a smooth sliding guide for the limiting rod 324, allowing the limiting rod 324 to maintain positional accuracy during linear movement. When the limiting rod 324 slides to the working position, its end can abut against the surface of the suture head 210, thereby achieving quick installation and reliable fixation of the suture head 210. Stable positioning of the needle position module can be completed without additional threaded locking or complex adjustment structures, significantly shortening replacement time and improving installation convenience.

[0034] The surface of the suture head 210 has two limiting grooves 325, which are located at one end of two limiting rods 324 respectively, and the two limiting rods 324 are slidably connected to the two limiting grooves 325 respectively.

[0035] In this embodiment, when the end of the limiting rod 324 slides into the corresponding limiting groove 325, it can achieve bidirectional limiting and anti-rotation constraint on the sewing head 210, ensuring that the sewing head 210 always maintains a stable position during high-speed sewing, avoiding loosening or displacement caused by vibration or lateral force, thereby ensuring sewing accuracy and equipment operation reliability.

[0036] The two limiting rods 324 are both set to an arc shape at one end, and the two limiting grooves 325 are adapted to the shape of the corresponding limiting rods 324.

[0037] In this embodiment, the arc-shaped structure at the end of the limiting rod 324 can form a natural guiding effect during the insertion into the limiting groove 325, reducing jamming and scratching during installation. The limiting groove 325 and the limiting rod 324 are matched in shape, so that the two form a stable surface contact positioning after being combined, which improves the stability and vibration resistance of the connection.

[0038] A spring 326 is installed through the surface of the limiting rod 324, and the other end of the spring 326 is fixedly connected to the guide tube 323.

[0039] In this embodiment, the spring 326 continuously applies an elastic preload to the limiting rod 324 under compressed conditions, so that the limiting rod 324 always keeps reliably pressed against the limiting groove 325, thereby forming a stable locking effect after the sewing head 210 is installed.

[0040] Pull rings 327 are fixedly installed at the ends of the two limiting rods 324 that are far apart, and the two pull rings 327 are located on both sides of the mounting tube 322 respectively.

[0041] In this embodiment, the pull ring 327 can be used as a manual release component for the limiting rod 324. The operator only needs to pull the corresponding pull ring 327 outward to overcome the elastic force of the spring 326 and make the limiting rod 324 disengage from the limiting groove 325, thereby realizing the quick unlocking and disassembly of the suture head 210, making the replacement process of the suture head 210 simpler and more efficient.

[0042] like Figure 2 , Figure 4 and Figure 5 As shown, the tensioning assembly 330 includes movable frames 333 disposed on both sides of the sewing table 310. Support rods 334 are fixedly installed on adjacent sides of the two movable frames 333. Two abutting tubes 335 are disposed on the surface of the support rods 334. The same abutting plate 336 is rotatably installed on the outer side of the two abutting tubes 335. The abutting plate 336 abuts against the sewing table 310.

[0043] In this embodiment, the clamping plate 336, with the cooperation of the support rod 334 and the clamping tube 335, can be adjusted along both sides of the sewing table 310, and through its close contact with the sewing table 310, it can evenly press and fix the edge of the electric vehicle seat cover to be sewn, preventing the material from wrinkling, shifting or loosening during the sewing process.

[0044] A torsion spring 337 is fixedly installed between the inside of the clamping tube 335 and the surface of the support rod 334, and the cross section of the clamping plate 336 is set as an isosceles rectangle.

[0045] In this embodiment, the torsion spring 337 can provide a continuous return force to the abutment plate 336, so that it can automatically return to the position that is tightly fitted with the sewing table 310 after the external force is released, thereby ensuring the continuous and stable pressing of the cushion cover during the sewing process. The abutment plate 336 adopts an isosceles rectangular cross-section design, which can evenly distribute pressure during pressing and reduce local indentations or deformation.

[0046] A first resistance slide rail 331 is fixedly installed on the surface of the processing base 100, and a second resistance slide rail 332 is fixedly installed at the output end of the first resistance slide rail 331. The second resistance slide rail 332 is connected to the sewing table 310 through a resistance universal joint.

[0047] In this embodiment, the first resistance slide rail 331 and the second resistance slide rail 332 are arranged in a cross shape, allowing the sewing table 310 to move freely in both forward and backward and left and right directions within the plane of the processing seat 100. The resistance universal joint provides uniform and controllable damping force when the sewing table 310 moves in multiple directions, enabling the sewing table 310 to remain stably in the target position after positioning, avoiding displacement due to inertia or external forces. At the same time, the resistance universal joint allows the sewing table 310 to rotate smoothly in any direction or adjust its angle, thereby meeting the flexible processing needs of the seat cushion cover under different sewing paths.

[0048] It should be noted that the first resistance slide rail 331 and the second resistance slide rail 332 are used to provide linear guidance and damping support during the movement of the sewing table 310, respectively. The first resistance slide rail 331 is fixedly installed on the surface of the processing base 100 and can provide stable sliding guidance for the second resistance slide rail 332 in the horizontal direction. At the same time, it applies appropriate resistance during the sliding process to prevent the sewing table 310 from overshooting or shaking due to inertia. The second resistance slide rail 332 is arranged in a direction perpendicular to the first resistance slide rail 331. After being connected to the sewing table 310, it can achieve smooth movement in another direction and also has a damping effect. Thus, with the cooperation of bidirectional guidance, the stability and processing accuracy of the sewing table 310 at any position are guaranteed.

[0049] Electric slide rails 338 are fixedly installed on both sides of the sewing table 310, and the output ends of the electric slide rails 338 are fixedly connected to two movable frames 333 respectively.

[0050] In this embodiment, the electric slide rail 338 can drive the corresponding moving frame 333 to move precisely back and forth along both sides of the sewing table 310 when driven, thereby realizing the simultaneous tightening or loosening of both sides of the seat cushion cover.

[0051] Working principle: First, the electric vehicle seat cover to be processed is laid flat on the sewing table 310. The moving frame 333 is driven to unfold to both sides by the electric slide rail 338, so that the tensioning component 330 is in a loose state, which facilitates the placement and positioning of the seat cover. After placement, the electric slide rail 338 drives the moving frame 333 to move inward in the opposite direction, which drives the support rod 334 and the pressing plate 336 to evenly press the edge of the seat cover. The torsion spring 337 provides a continuous return force to ensure that the force is even and the fit is stable during the pressing process. Then, according to the processing path, the operator adjusts the position and direction of the sewing table 310 by the cross sliding cooperation of the first resistance slide rail 331 and the second resistance slide rail 332. The resistance universal joint provides stable damping in multi-directional movement, so that the sewing table 310 can accurately stop at the target position and avoid displacement during processing. After the sewing preparation is completed, the sewing head 210 starts and performs sewing operations according to the preset program. The feeding, presser foot and needle bar mechanism work together to continuously sew the edges of the fabric or leather of the seat cover. During processing, if it is necessary to change to a different model of sewing needle or stitch length specification, the limiting rod 324 can be released through the pull ring 327, causing it to disengage from the limiting groove 325. The original sewing head 210 can then be quickly removed, and the new sewing head 210 can be installed into the module assembly 320 and locked in place by the limiting rod 324. This eliminates the need to disassemble other parts, significantly shortening the replacement time. During sewing, the tensioning assembly 330 continuously maintains the flatness of the seat cover, ensuring that the stitches are evenly arranged and the appearance is neat.

[0052] It should be noted that the stitching head, electrical connector, and motorized slide rail mentioned above are all devices with relatively mature existing technologies. Specific models can be selected according to actual needs. At the same time, the stitching head, electrical connector, and motorized slide rail can be powered by the built-in power supply or by AC power. The specific power supply method should be selected according to the situation, and will not be elaborated here.

[0053] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model 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 will 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 utility model.
