Description

Technical Field

[0001] The utility model relates to the technical field of motorcycle and electric vehicle, in particular to a heat-sealing device for a seat cushion leather cover of a motorcycle and electric vehicle. Background Art

[0002] The manufacturing of leather seat covers for motorcycles and electric vehicles, particularly those with integrated ties, requires a perfect fit for the diverse and often irregular shapes of these cushions. Current production methods rely primarily on manual sewing using sewing machines, which places high demands on worker skill, resulting in operational difficulties and low production efficiency. Due to the limitations of manual sewing, dimensional consistency and accuracy of the finished product are difficult to ensure, leading to significant dimensional variation between products and compromising product quality.

[0003] Furthermore, leather covers sewn with a sewing machine present significant drawbacks during use: the threading area can easily allow moisture to enter the seat cushion, leading to damage. While some manufacturers apply glue to the seams to create a seal, this treatment only effectively prevents moisture penetration in the short term. Over time, the glue loses its effectiveness due to aging, ultimately failing to completely resolve the water seepage issue, severely impacting product durability and user satisfaction.

[0023] The following is an explanation and description of the technical solutions of the embodiments of the present invention in conjunction with the drawings of the embodiments of the present invention, but the following embodiments are only preferred embodiments of the present invention and are not exhaustive. Based on the embodiments in the embodiments, other embodiments obtained by those skilled in the art without creative work are all within the scope of protection of the present invention.

[0024] The following is a detailed description of the heat-sealing device for a motorcycle or electric vehicle seat cushion leather cover according to an embodiment of the present invention with reference to the accompanying drawings. Example

[0025] For easier understanding, see Figures 1 to 3 An embodiment of a heat-sealing device for a motorcycle or electric vehicle seat cushion leather cover provided by the utility model comprises:

[0026] An upper mold 1 and a lower mold 2 that are butted against each other;

[0027] The outer wall of the lower mold 2 is fixedly connected to a plurality of clamping platforms 21, and the clamping platforms 21 are distributed around the periphery of the lower mold 2;

[0028] A clamp 22 for fixing two pieces of leather and a strap is provided on the top of each clamping platform 21. The clamp 22 is used to ensure that the positions of the two pieces of leather and the strap remain unchanged during the welding process.

[0029] It should be noted that the heat-sealing device primarily comprises an upper mold 1 and a lower mold 2, which are butt-jointed. Multiple clamping platforms 21 are fixedly connected to the outer wall of the lower mold 2 and distributed around the periphery of the lower mold 2. Each clamping platform 21 is topped with a clamp 22, which secures the two pieces of leather and a bridle during the welding process, ensuring they remain in place.

[0030] In some embodiments, a plurality of first mounting members 11 are fixedly connected to the outer wall of the upper mold 1 , and the first mounting members 11 are arranged around the upper mold 1 ;

[0031] The outer wall of the lower mold 2 is fixedly connected to the corresponding position of the second mounting members 23, which are the same in number and corresponding in position as the first mounting members 11;

[0032] The first mounting member 11 is connected to the corresponding second mounting member 23 via a positioning pin 3 to ensure that the upper mold 1 and the lower mold 2 are aligned when docked.

[0033] It should be noted that to ensure precise alignment of the upper mold 1 and lower mold 2 during mating, multiple first mounting members 11 are fixedly connected to the outer wall of the upper mold 1, arranged in a circumferential manner. Correspondingly, an equal number of second mounting members 23, positioned in corresponding positions, are fixedly connected to the outer wall of the lower mold 2. The first mounting members 11 and the second mounting members 23 are connected by locating pins 3, ensuring precise alignment of the upper mold 1 and lower mold 2 during mating.

[0034] In some embodiments, the clip 22 is suitable for clamping two pieces of leather of different thicknesses and a strap.

[0035] It should be noted that, considering the requirements for materials of different thicknesses, the clip 22 is adaptable and can clamp two pieces of leather and a strap of different thicknesses, which makes the device suitable for the production of products of various specifications.

[0036] In some embodiments, the upper mold 1 is integrated with an ultrasonic generator for welding two pieces of leather and a bridle clamped by the upper mold 1 and the lower mold 2.

[0037] It's important to note that to achieve efficient welding, upper mold 1 incorporates an integrated ultrasonic generator. When upper and lower molds 1 and 2 are closed, the ultrasonic generator activates, using ultrasonic energy to weld the two pieces of leather and the strap secured by clips 22. Ultrasonic welding technology quickly delivers sufficient heat to melt the material surface while maintaining a cool surrounding environment, effectively bonding the leather and strap together without damaging the materials or affecting their appearance.

[0038] Working Principle: The operator prepares two pieces of leather and a strip of thong to be welded. These materials will form part of a seat cushion cover. The operator places the two pieces of leather and the strip of thong in the clamps 22 and adjusts the clamps 22 to accommodate the varying thicknesses of the materials, ensuring they remain secure during the welding process. The upper and lower molds 1 and 2 are precisely aligned using the first and second mounting members 11 and 23 secured to their outer walls, along with the locating pins 3. The locating pins 3 ensure perfect alignment when the upper and lower molds are closed, ensuring the precise welding position. Once the upper and lower molds 1 and 2 are successfully aligned, the ultrasonic generator integrated into the upper mold 1 is activated. This ultrasonic generator generates high-frequency vibration energy, which is transmitted through the upper mold 1 to the contact surface between the leather and the thong. The ultrasonic energy causes the contact surface between the leather and the thong to vibrate rapidly, generating frictional heat, which rapidly softens or melts the material in the contact area. As the material melts, under a certain pressure, the two pieces of leather and the thong fuse together at the contact point, forming a strong weld. Because ultrasonic welding is fast and focused, surrounding materials are not affected by excessive heat, ensuring that the quality of materials outside the weld point is not damaged. The upper mold 1 and lower mold 2 separate, and the operator can open the clamp 22 and carefully remove the finished seat cushion leather cover.

[0039] As described above, the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit them. Although the present application has been described in detail with reference to the above embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the above embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the embodiments of the present application.
