Description

Technical Field

[0001] This application relates to the field of luggage technology, and in particular to a luggage frame and a luggage. Background Technology

[0002] The diversification of modern travel modes has significantly broadened the application scenarios of suitcases, covering various travel modes such as daily commutes and business trips, and making them an important piece of equipment in the modern integrated travel system. Consequently, user demands have also become more complex: not only are products required to achieve higher storage efficiency and mobility stability within limited space, but higher standards are also being set for aesthetic design and visual experience.

[0003] In the existing technology, vacuum forming is the mainstream process for manufacturing suitcase bodies. However, due to the inherent limitations of this process, the suitcase body cannot be formed in one piece; the front and rear bodies must be manufactured separately, and then assembled into a complete suitcase body using suitcase frame strips.

[0004] Chinese patent application publication number CN111955877A discloses a front-opening structure I-shaped nailing method for a suitcase, including a small front cover, which is connected to the front box body by a zipper. A connecting frame is connected between the front box body and the rear box body. A slot is provided above the I-shaped frame, and a tube is connected to the slot. The front box body, the rear box body and the I-shaped frame are all reinforced and connected by hollow nails.

[0005] However, using the above-mentioned I-frame combined with hollow nails will leave protruding nails at the joint between the front and rear boxes, resulting in an uneven outer surface of the suitcase, affecting the tactile feel and overall aesthetics. Utility Model Content

[0006] To overcome the problem of poor feel and reduced aesthetics caused by protruding nails at the seams of a suitcase, this application provides a suitcase frame strip and a suitcase.

[0007] Firstly, the luggage frame strip provided in this application adopts the following technical solution: A luggage frame includes a connecting frame for connecting to a front compartment and a rear compartment. The connecting frame includes a connecting strip, an inner sealing strip fixedly connected to one end of the connecting strip, and an outer sealing strip fixedly connected to the other end of the connecting strip. The outer sealing strip and the inner sealing strip are separated by the connecting strip into a front connecting area for inserting the front compartment and a rear connecting area for inserting the rear compartment. The inner sealing strip has grooves on both sides for fastening screws to be driven into.

[0008] By adopting the above technical solution, the front box and the rear box can be inserted into the front connection area and the rear connection area respectively, so as to realize the quick positioning and connection of the box and the connection frame; the groove provides pre-positioning for the fastening screw before it is driven in, and the inner sealing strip is thinner at the groove, which can reduce the driving resistance of the fastening screw during driving.

[0009] Optionally, positioning grooves are provided on both sides of the outer sealing strip at positions corresponding to the groove.

[0010] By adopting the above technical solution, the positioning groove provides guidance and positioning for the end of the fastening screw, avoiding deviation during the insertion process.

[0011] Optionally, a decorative strip for covering the inner seal is also included.

[0012] By adopting the above technical solution, the decorative strip can cover the exposed inner sealing strip and fastening screws, which can improve the appearance while effectively preventing dust accumulation and scratches.

[0013] Optionally, the inner seal strip has support protrusions connected to both ends on the side opposite to the outer seal strip, and a receiving cavity for accommodating the head of the fastening screw is formed between the inner seal strip and the decorative strip.

[0014] By adopting the above technical solution, the supporting protrusions can not only support the decorative strips, but also ensure that the inner surface of the suitcase is flat.

[0015] Optionally, the decorative strip includes a cover sheet and a protrusion connected to the cover sheet, and a connecting block is connected to the side of the inner seal strip opposite to the outer seal strip, and the connecting block is provided with a slot for insertion of the protrusion.

[0016] By adopting the above technical solution, the snap-fit ​​between the protrusion and the slot achieves a reliable connection between the connecting frame and the decorative strip.

[0017] Optionally, the protrusion includes a connecting part and a limiting part that are connected to each other, the slot includes a connecting groove and a limiting groove that are connected to each other, the opening of the connecting groove is provided with a rounded corner, the limiting part is engaged with the limiting groove, and the connecting part is engaged with the connecting groove.

[0018] Optionally, the width of the decorative strip is greater than or equal to the width of the inner sealing strip.

[0019] By adopting the above technical solution, the decorative strip can completely cover the exposed inner sealing strip and fastening screws, which on the one hand protects the inner sealing strip and fastening screws from dust intrusion and scratches, extending their service life, and on the other hand eliminates the adverse effects on the user's tactile feel, combining aesthetics and user comfort.

[0020] By adopting the above technical solution, a multi-layered snap-fit ​​engagement between the protrusion and the slot is achieved. The engagement between the connecting part and the connecting groove provides basic positioning and fixation for the snap-fit ​​between the connecting frame and the decorative strip. The engagement between the limiting part and the limiting groove improves the stability of the connection between the connecting frame and the decorative strip.

[0021] Optionally, the thickness ratio of the outer seal to the inner seal is 1.

[0022] By adopting the above technical solution, the outer sealing strip directly exposed to the outside has better impact resistance and wear resistance, providing a solid protective barrier for the joint between the front and rear boxes.

[0023] Optionally, the ratio of the width of the outer seal to the width of the inner seal is 1.

[0024] By adopting the above technical solutions, the slightly narrower outer sealing strip effectively reduces its visual proportion in the appearance of the box, improving the overall aesthetics; the slightly wider inner sealing strip increases the contact area with the front and rear boxes, which helps to improve the firmness and sealing of the connection.

[0025] Secondly, the suitcase provided in this application adopts the following technical solution: A suitcase includes a front body, a rear body disposed opposite to the front body, a suitcase frame, and fastening screws connected to the suitcase frame. The edge of the front body is inserted into a front connecting area, the edge of the rear body is inserted into a rear connecting area, and the fastening screws penetrate the edge of the front body or the rear body.

[0026] By adopting the above technical solution, the suitcase achieves a stable connection between the front and rear compartments through the internal nailing method of connecting frame and fastening screws, and also achieves a smooth inner and outer surface of the suitcase, improving the overall aesthetics of the product.

[0027] In summary, this application has the following beneficial effects: 1. The luggage frame and luggage of this application, through the connection method of combining the connecting frame with internal nails, not only achieve a reliable connection between the front and rear boxes, but also hide the fastening screws inside the box, improving the flatness and aesthetics of the outer surface of the box.

[0028] 2. By interlocking the decorative strip with the luggage frame strip, the exposed inner sealing strip and fastening screws at the seams of the luggage body are effectively covered. This not only eliminates the adverse effects of surface protrusions on the user's tactile experience, but also provides dustproof and scratch-proof protection for the seam area, improving the product's comfort and durability.

[0031] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0032] This application discloses a luggage frame and a luggage.

[0033] Reference Figure 1 The suitcase includes a front compartment 4, a rear compartment 5 opposite to the front compartment 4, a suitcase frame connected to the front compartment 4 and the rear compartment 5, and fastening screws 1 fixedly connected to the suitcase frame.

[0034] The luggage frame includes a connecting frame 2 for connecting the front compartment 4 and the rear compartment 5, and a decorative strip 3 for covering the connecting frame 2. The connecting frame 2 and the decorative strip 3 are snap-fitted together. The connecting frame 2 is made of aluminum alloy profile, which significantly enhances the structural rigidity and bending strength at the joint between the front compartment 4 and the rear compartment 5. The decorative strip 3 is a soft rubber strip, which maintains a good appearance and tactile feel while possessing excellent bending resistance and tensile elasticity.

[0035] Reference Figure 1 , Figure 2The connecting frame 2 has a symmetrical structure and includes a connecting strip 21, an inner sealing strip 23 fixedly connected to one end of the connecting strip 21, and an outer sealing strip 22 fixedly connected to the other end of the connecting strip 21. The thickness ratio of the outer sealing strip 22 to the inner sealing strip 23 is (1.3-2):1, preferably 1.5:1 in this embodiment, so that the outer sealing strip 22 exposed on the outer surface of the suitcase has better impact resistance and wear resistance, and also provides a solid protective barrier for the joint between the front and rear boxes 4 and 5. The width ratio of the outer sealing strip 22 to the inner sealing strip 23 is (0.4-0.8):1, preferably 0.6:1 in this embodiment. The slightly narrower outer sealing strip 22 reduces its visual proportion on the outer surface of the suitcase, and the slightly wider inner sealing strip 23 increases its contact area with the front and rear boxes 4 and 5, further improving the stability of the connection.

[0036] The inner sealing strip 23 has symmetrical grooves 231 on both sides for positioning the fastening screws 1, and the outer sealing strip 22 has symmetrical positioning grooves 221 on both sides corresponding to the positions of the grooves 231. The outer sealing strip 22 and the inner sealing strip 23 are separated by a connecting strip 21 into a front connecting area 26 for inserting the edge of the front housing 4 and a rear connecting area 27 for inserting the edge of the rear housing 5.

[0037] When connecting the front housing 4 and the rear housing 5 to the connecting frame 2, first insert the edge of the front housing 4 into the front connecting area 26, and the rear housing 5 into the rear connecting area 27. Then, align the end of the fastening screw 1 with the inner wall of the groove 231. The groove 231 provides pre-positioning for the fastening screw 1, effectively preventing displacement when the fastening screw 1 is driven in, and reducing resistance for subsequent driving. The fastening screw 1 penetrates the bottom wall of the groove 231 and passes through the edge of the front housing 4 or the rear housing 5 until the end of the fastening screw 1 abuts against the bottom wall of the positioning groove 221, thus completing the connection between the connecting frame 2 and the front housing 4 and the rear housing 5.

[0038] Reference Figure 2 , Figure 3 as well as Figure 4 The decorative strip 3 includes a cover plate 31 and a protrusion 32 fixedly connected to the middle of the cover plate 31. The protrusion 32 includes a connecting part 322 and a limiting part 321 that are connected to each other. The width of the cover plate 31 is greater than or equal to the width of the inner sealing strip 23. In this embodiment, it is preferable that the width of the cover plate 31 is greater than the width of the inner sealing strip 23. Supporting protrusions 232 for supporting the cover plate 31 are fixedly connected to both ends of the side of the inner sealing strip 23 away from the outer sealing strip 22. A connecting block 24 is fixedly connected to the middle of the side of the inner sealing strip 23 away from the outer sealing strip 22. A slot 25 for the protrusion 32 to be inserted is provided in the connecting block 24. The slot 25 includes a connecting groove 252 and a limiting groove 251 that are connected. The opening of the connecting groove 252 is provided with a rounded corner 253 to facilitate the insertion of the protrusion 32.

[0039] During the connection process between the connecting frame 2 and the decorative strip 3, the rounded corner 253 can be used to smoothly guide the limiting part 321 and insert it into the connecting groove 252. Continue to insert until the limiting part 321 and the limiting groove 251 are engaged, and at the same time the connecting part 322 and the connecting groove 252 are engaged, thus completing the reliable connection between the two.

[0040] In this connected state, the cover plate 31 can cover the outer surface of the inner seal strip 23. Furthermore, the cover plate 31 is wider than the inner seal strip 23, achieving complete coverage of the inner seal strip 23. A receiving cavity 33 is formed between the cover plate 31 and the inner seal strip 23, providing space for the inner seal strip 23 and the head of the fastening screw 1.

[0041] The implementation principle of a luggage frame strip and luggage in this application embodiment is as follows: First, insert the edge of the front box 4 into the front connecting area 26 and the edge of the rear box 5 into the rear connecting area 27. Then, use fastening screws 1 to penetrate the bottom wall of the groove 231 and pass through the edge of the front box 4 or the rear box 5 until they abut against the bottom wall of the positioning groove 221. Finally, cover the inner side of the inner sealing strip 23 with the decorative strip 3 and insert the protrusion 32 into the slot 25 to complete the installation of the luggage frame strip.

[0042] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
