Description

Technical Field

[0001] This utility model relates to the field of general vehicle technology, and in particular to a corner structure for connecting strips. Background Technology

[0002] With the continuous innovation of modern technology, more and more buses are adopting the use of linoleum flooring in their interior design to enhance the overall aesthetics of the passenger cabin, thereby improving the passenger experience and comfort. The neatness and seamlessness of the linoleum flooring installation directly affect the overall aesthetics of the bus. During installation, floor strips are typically laid at the joints or edges of the linoleum flooring to secure it. Corner strips are used at the corners of the floor strips to secure the corner linoleum and connect two floor strips.

[0003] Chinese utility model patent document with authorization announcement number CN203450047U and authorization announcement date of 2014 / 02 / 26 discloses a plastic corner strip for bus floor. The corner strip includes a strip body in the shape of a right angle, inner and outer skirts with rounded transitions on the inner and outer sides of the strip body, and threaded fixing holes and decorative grooves on the upper surface of the strip body. The strip body and the inner and outer skirts are integrally injection molded by an injection molding machine.

[0004] Traditional floor trim strips require beveled edges at corners to join two strips. This often results in misalignment or uneven seams. While this corner trim strip solves the problem of uneven cutting at corners, it directly presses onto the corresponding floor trim strips on both sides. This leads to inconsistent heights between the floor trim and the corner trim, creating protrusions. Furthermore, the decorative groove on the upper surface of this corner trim strip prevents the insertion of an insert strip when used in bus floors. This causes the insert strip on the floor trim strip to be interrupted at the corner, disrupting the continuity of the insert strip after joining. Therefore, this corner trim strip design fails to maintain the overall aesthetics and consistency of the vehicle interior. Utility Model Content

[0005] The purpose of this utility model is to provide a corner structure for connecting floor strips, so as to solve the problems that protrusions easily appear when the floor strips are pressed and the inlay strips on the floor strips are not continuous at the corners, resulting in poor overall aesthetics and consistency in the passenger car cabin.

[0006] To solve the above problems, the corner structure of the pressure strip of this utility model adopts the following technical solution:

[0007] A corner structure for floor molding strips includes a corner member. The upper side of the corner member is provided with a through-core mounting groove that extends to the shape of the corner member and is angular, for installing through cores. The two ends of the corner member are mating surfaces for aligning and splicing with the ends of the corresponding floor molding strips. The shape of the mating surfaces is the same as the cross-sectional shape of the floor molding strip, so that the two ends of the through-core mounting groove are aligned and connected with the through-core mounting grooves on the corresponding floor molding strips.

[0008] Furthermore, the through-core mounting groove is a closing groove.

[0009] Furthermore, the angular member has a through screw connection hole on the bottom of the through-core mounting groove.

[0010] Furthermore, there are two or more screw connection holes.

[0011] Furthermore, there are two screw connection holes, which are located near the end of the through-core mounting groove.

[0012] Furthermore, the screw connection hole is a countersunk hole.

[0013] Furthermore, the angular component is a one-piece molded part.

[0014] Furthermore, the angular component is an aluminum alloy component.

[0015] Beneficial Effects: The corner structure for mating strips of this utility model is a pioneering invention. This corner structure includes a corner member with a through-hole mounting groove. The corner member also includes a mating surface with the same cross-sectional shape as the end of the corresponding floor trim strip. This identical cross-section design ensures a high degree of matching between the corner member and the corresponding floor trim strip during mating, thus avoiding interference, protrusions, or dimensional inconsistencies. It also improves the smoothness and flatness of the connecting strips inserted into the through-hole mounting groove, thereby enhancing the overall aesthetics and consistency of the passenger compartment. Therefore, this corner structure can achieve mating between the corner member and the corresponding floor trim strip while also meeting the requirements for smooth and flat connecting strips.

[0019] The features and performance of this utility model will be further described in detail below with reference to the embodiments.

[0020] An embodiment of the pressure strip joint corner structure of this utility model is as follows:

[0021] The corner structure of this utility model uses mating surfaces with the same cross-section to achieve the fit between the corner piece and the corresponding floor trim, and the through-core mounting groove set on the corner piece can realize the continuous arrangement of the trim, thereby improving the overall aesthetics and consistency of the passenger car cabin.

[0022] Based on the above inventive concept, as a basic solution, such as Figure 1-2 As shown, the corner structure of the floor strip connection of this utility model includes a corner member 1, which is used to fix the floor and floor covering at the corner and to connect the two floor strips 2, so that the floor strips 2 in the passenger compartment have continuity as a whole, thereby giving the passenger compartment better integrity and aesthetics. The upper side of the angular component 1 is provided with an angled mounting groove 3 for installing the core, which extends with the shape of the angular component 1. The two ends of the angular component 1 are mating surfaces for aligning and splicing with the ends of the corresponding floor strips 2. The shape of the mating surfaces is the same as the cross-sectional shape of the floor strips 2, so that the two ends of the mounting groove 3 are aligned and connected with the mounting groove 3 on the corresponding floor strips 2. Keeping the cross-sectional shape the same ensures the matching degree between the angular component 1 and the corresponding floor strips 2 on both sides when they are mated, thereby avoiding interference, protrusions, inconsistent dimensions, and other adverse conditions. It also ensures the continuity of the inlay strips set in the mounting groove 3. The inlay strips on the bus floor strips 2 are usually floor coverings or warning lines. Floor coverings can play a decorative and aesthetic role, or warning lines can remind passengers to pay attention to the safety of the bus. Therefore, the continuous setting of the inlay strips can maintain the visual uniformity and aesthetics of the passengers, and help avoid phenomena such as uneven connection of the inlay strips, thereby improving the overall aesthetics and consistency of the bus cabin.

[0023] In another embodiment, the corner of the corner component 1 is a right-angle bend. Preferably, the corner of the corner component 1 is a rounded transition. The rounded transition not only avoids the collision of sharp edges and right angles, but also helps to improve the aesthetics of the corner component 1.

[0024] As a preferred implementation method, such as Figure 1As shown, the through-hole mounting groove 3 is a tapered groove. After the insert strip is inserted into the through-hole mounting groove 3, the tapered groove design can prevent the insert strip from moving freely, which would cause wrinkles, falling off, or curling edges. The insert strip can cover the screws 5 used to connect the corner piece 1 to the floor in the through-hole mounting groove 3, and the flat insert strip can improve the overall aesthetics of the passenger compartment, further providing passengers with a better riding experience. In addition, when the insert strip (such as floor covering) inserted into the through-hole mounting groove 3 is cut to a size that matches the groove, it is easy to form rough edges at the edges. Therefore, the tapered design of the through-hole mounting groove 3 can also cover the rough edges and improve the neatness. In other embodiments, the groove wall and the bottom of the through-hole mounting groove 3 are set vertically or it is set as a flared groove. The insert strip in the groove can be fixed by adhesive during installation, which can also achieve the purpose of preventing its movement or wrinkles.

[0025] In a preferred embodiment, the corner piece 1 has a through screw connection hole at the bottom of the through-core mounting groove 3. A screw 5 is installed in the screw connection hole to connect the corner piece 1 to the floor. The screw 5 allows for a detachable connection between the corner piece 1 and the floor. After prolonged use, this facilitates the removal, cleaning, or replacement of the floor covering in the bus cabin. Furthermore, the screw 5 has a simple structure and is easy to install; it can be tightened or loosened using a wrench or a hand drill. Additionally, the screw 5 is highly standardized, making it easy to purchase various types of screws at a low cost. In other embodiments, no screw connection hole is provided; a self-tapping screw can be used to directly drill through the corner piece 1 and connect it to the floor using a hand drill.

[0026] In a preferred embodiment, the screw connection holes are two or more, providing at least two connection positions for the screws 5. This improves the stability and reliability of the connection between the corner piece 1 and the floor, preventing rotation or loosening of the corner piece 1 when connected at one position. The redundant design of multiple screw connections also enhances connection flexibility; if one screw 5 becomes loose or falls off, the others can still ensure the stability of the connection between the corner piece 1 and the floor, providing sufficient time for maintenance personnel to replace the faulty screw 5. In other embodiments, the screw connection holes can be three or other numbers. Specifically, the number of screw connection holes can be changed according to the size of the corner piece 1 to increase the number of screw connection positions, thereby improving connection stability.

[0027] As a preferred implementation method, such as Figure 1-2 As shown, there are two screw connection holes, which are located near the end of the through-core mounting groove 3. The screw connection holes at this location can achieve stability and reliability of the connection between the corner piece 1 and the floor by using a smaller number of screws 5.

[0028] As another preferred implementation, such as Figure 1-2 As shown, the screw connection hole is a countersunk hole 4. The countersunk hole 4 is designed to allow the screw 5 to be recessed, thereby avoiding the screw head from protruding too high in the through-core mounting groove 3 and causing unevenness. When laying floor linoleum or warning strips, the design of recessing the screw 5 can maintain sufficient flatness, thereby improving the aesthetics in the details and improving the overall quality of the bus.

[0029] As a preferred embodiment, the corner component 1 is a one-piece molded part. The one-piece molding design has a short production cycle and can achieve mass production, thereby reducing the processing steps of the through-core mounting groove 3, screw 5 holes and other structures, thus improving processing efficiency; and the one-piece molding of the corner component 1 can improve its overall strength and stability.

[0030] In a preferred embodiment, the corner component 1 is an aluminum alloy component. Aluminum has advantages such as lightweight, high strength, and high hardness, which can effectively cope with the phenomenon of the floor strip 2 being stepped on, maintaining its original state without deformation, thereby extending its service life, reducing the frequency of replacement, and lowering replacement costs. Furthermore, aluminum also has good surface gloss and texture, which can effectively enhance the overall aesthetics of the bus cabin when applied to the floor strip 2. A casting process can be used to form the aluminum corner component 1 as a single piece. Specifically, molten aluminum is poured into a mold, and after cooling, the desired aluminum alloy corner component 1 is formed. In other embodiments, PVC (polyvinyl chloride) corner components 1 can also be used. PVC material also has high strength and toughness, and can withstand certain pressure and impact. An injection molding process can be used to integrally mold the corner component 1.

[0031] The specific usage process of the pressure strip joint corner structure of this utility model is as follows: (e.g.) Figure 1-2 As shown, the corner structure of this utility model can be specifically processed according to the cross-sectional shape of the floor strip 2 that needs to be connected, so that the cross-sections of the two are the same so that the corner structure can better connect with the floor strip 2. The corner structure and the floor strip 2 are connected by screws 5 installed in the countersunk holes 4 set on the bottom of the through-core mounting groove 3. Finally, floor linoleum or warning line can be laid in the through-core mounting groove 3 as needed, which can cover the screws 5 and achieve a decorative effect or a warning reminder purpose.

The patent protection scope of the present utility model shall be determined by the claims. Similarly, any equivalent structural changes made based on the description and drawings of the present utility model shall also be included within the protection scope of the present utility model.
