[0030] This utility model provides a composite handle assembly for a suitcase and a suitcase, which can improve the comfort and cushioning of the handle assembly while ensuring strong support, thereby enhancing user comfort and extending the service life of the handle assembly.

[0031] like Figures 1 to 3 As shown, this embodiment of the utility model provides a luggage composite handle assembly 100. The luggage composite handle assembly 100 includes a handle body 110, with connecting portions 120 at both ends. The handle body 110 is connected to the suitcase body 210 of the luggage 200 through the connecting portions 120. The handle body 110 also has a grip portion 130 on the side near the suitcase body 210. A support layer 140 and a buffer layer 150 are sequentially provided along the thickness direction of the handle body 110. The support layer 140 is located on the outside of the handle body 110 and is made of a rigid material. The buffer layer 150 protrudes from the grip portion 130 and is matched and connected to the support layer 140. The buffer layer 150 is made of a flexible material.

[0032] This utility model's technical solution involves setting up a composite handle assembly 100, with a support layer 140 and a buffer layer 150 sequentially arranged along the thickness direction of the handle body 110. The buffer layer 150 protrudes from the grip portion 130 and is matched and connected to the support layer 140. The support layer 140 is made of rigid material, and the buffer layer 150 is made of flexible material. Through the multi-layer composite structure design, the support of the rigid material helps to prevent deformation of the handle assembly 100, and the buffer layer 150 protrudes and conforms to the user's palm, reducing pressure when gripping. While ensuring strong support for the handle assembly 100, this design improves the comfort and buffering properties of the handle assembly 100, enhances user comfort, and extends the service life of the handle assembly 100.

[0033] like Figures 1 to 3 As shown, the buffer layer 150 includes a gripping area 151 and a connecting area 152. The connecting area 152 is located at both ends of the gripping area 151 and is used to connect with the support layer 140. The thickness of the gripping area 151 is greater than the thickness of the connecting area 152. The outer surface of the buffer layer 150 forms an arc-shaped contact surface. This utility model's technical solution, by forming an arc-shaped contact surface on the outer surface of the buffer layer 150, improves grip elasticity and comfort while ensuring structural stability, which helps reduce pressure during gripping and improves comfort. In this application, the buffer layer 150 is integrally formed with the support layer 140 by bonding, injection molding, or compression molding.

[0034] Preferably, the material density of the flexible material in the gripping area 151 is less than that in the connecting area 152. This invention provides a softer feel and better cushioning by using a thicker, less dense flexible material in the gripping area 151, making it suitable for prolonged gripping. Conversely, using a thinner, more dense flexible material in the connecting area 152 ensures a reliable connection with the support layer 140, preventing the cushioning layer 150 from detaching.

[0035] Specifically, in one embodiment, the gripping area 151 has a thickness of 5 mm and a material density of 0.8 g / cm³, while the connecting areas 152 at both ends have a thickness of 3 mm and a material density of 1.0 g / cm³.

[0036] Specifically, in this application, the support layer 140 includes a rigid skeleton and a molding material covering the skeleton. The molding material can be made of plastic. The cushioning layer 150 includes thermoplastic-rubber (TPR), which can provide good rebound support and improve the grip experience. In addition to TPR, other flexible materials such as silicone can also be selected for the cushioning layer 150 according to actual needs.

[0037] Furthermore, antibacterial agents or fragrances can be added to the cushioning layer 150 to improve the hygiene and user experience of the handle assembly 100. The outer surface of the cushioning layer 150 can also be covered with a breathable fabric to facilitate breathability during gripping and improve user comfort.

[0038] like Figures 1 to 3 As shown, preferably, the surface of the grip area 151 is provided with an anti-slip structure 153. This utility model's technical solution, by providing an anti-slip structure 153 on the surface of the grip area 151, helps to increase the friction between the handle assembly 100 and the user's hand, preventing slippage and improving safety during use.

[0039] Specifically, such as Figure 1 As shown, the anti-slip structure 153 consists of anti-slip protrusions arranged at intervals. Those skilled in the art can also provide other forms of anti-slip structure 153 according to actual needs, such as anti-slip textures, concave-convex structures, etc. This application does not limit the specific form of the anti-slip structure 153.

[0040] like Figures 2 to 3 As shown, preferably, the support layer 140 is further provided with reinforcing ribs 141 inside. The reinforcing ribs 141 are distributed in a grid pattern inside the support layer 140 to enhance the overall strength of the handle assembly 100. The reinforcing ribs 141 can be made of plastic and integrally injection molded with the support layer 140, or they can be made of other strong support materials.

[0041] like Figure 3 As shown, in another embodiment of this application, at least one interlayer 160 is further provided between the support layer 140 and the buffer layer 150, and the thickness of the interlayer 160 is less than the thickness of the buffer layer 150 and the support layer 140. For example, the thickness of the interlayer 160 is 1-2 mm, the thickness of the buffer layer 150 is 3-8 mm, and the thickness of the rigid support layer 140 is 3-5 mm. This utility model's technical solution, by providing an interlayer 160 between the support layer 140 and the buffer layer 150, helps to further enhance the shock absorption effect and structural stability of the handle assembly 100.

[0042] Furthermore, the interlayer 160 can adopt a honeycomb, mesh, or corrugated structure to enhance structural strength and shock absorption performance while reducing weight. The interlayer 160 can be fixed between the support layer 140 and the buffer layer 150 by hot pressing or adhesive bonding.

[0043] In this application, the interlayer 160 includes a flexible material and / or a polymer reinforcing material. The present invention's technical solution, by incorporating a flexible material in the interlayer 160, facilitates vibration absorption. Specifically, the flexible material of the interlayer 160 can be ethylene-vinyl acetate copolymer (EVA), silicone, or similar materials. Alternatively, shock-absorbing springs can be uniformly arranged between the buffer layer 150 and the support layer 140, with both ends of the springs connected to the support layer 140 and the buffer layer 150 respectively, effectively absorbing vibrations during the movement of the suitcase 200 and reducing impact on the hands. Incorporating a polymer reinforcing material in the interlayer 160 improves the impact resistance of the handle. Specifically, the polymer reinforcing material of the interlayer 160 can be made of elastic fiber cloth or similar materials.

[0044] like Figures 4 to 5 As shown, this utility model embodiment provides a suitcase 200, which includes a suitcase body 210, a pull rod assembly 220, and a handle assembly 230. The pull rod assembly 220 and the handle assembly 230 are respectively connected to the suitcase body 210. The pull rod assembly 220 and the handle assembly 230 each include a composite handle assembly 100 according to any of the foregoing embodiments of this utility model.

[0045] This utility model's technical solution involves setting composite handle assemblies 100 in the pull rod assembly 220 and the handle assembly 230 of the suitcase 200. The handle assembly 100 has a support layer 140 and a buffer layer 150 sequentially arranged along the thickness direction of the handle body 110. The buffer layer 150 protrudes from the grip portion 130 and is matched and connected to the support layer 140. The support layer 140 is made of rigid material, and the buffer layer 150 is made of flexible material. Through this multi-layer composite structure design, the rigid material's support helps prevent deformation of the handle assembly, while the buffer layer 150 protrudes and conforms to the user's palm, reducing pressure during gripping. While ensuring strong support for the handle assembly 100, this design improves the comfort and buffering properties of the handle assembly 100, enhances user comfort, and extends the service life of both the handle assembly 100 and the suitcase 200.

[0046] Understandably, when the handle assembly 100 is applied to the pull rod assembly 220, the connecting part 120 is fixedly connected to the pull rod assembly 220 via mounting holes and bolts or snap-fit ​​structures, resulting in a strong connection and high stability under pulling force. The pull rod assembly 220 also includes a button and a pull rod; pressing the button extends the pull rod. When the handle assembly 100 is applied to the carrying handle assembly 230, the connecting part 120 is connected to the outside of the suitcase 200 body 210 via a rotating connector. The rotating connector includes a mounting base and a rotating shaft, allowing the carrying handle assembly 230 to rotate flexibly around the rotating shaft, facilitating the user to lift the suitcase 200 at different angles.

[0047] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
