Description

Technical Field

[0001] This invention relates to the field of transportation equipment accessories technology, specifically to a tool-free installation guide rail for the glass of transportation equipment and its installation method. Background Technology

[0002] Side window glass of transportation equipment is usually installed via upper glass guide rails. The upper glass guide rails extend along the top of the side wall of the vehicle. The upper edge of the glass is suspended on the upper glass guide rails via sliding components. Pushing the glass allows it to slide along the length of the upper glass guide rails, thus achieving the opening and closing adjustment of the glass. The installation stability of the upper glass guide rails directly affects the performance of the glass.

[0003] Currently, when installing the glass guide rail, installers first mark the installation position of the guide rail on the top of the side panel of the vehicle body. They then use a drill to drill multiple mounting holes in the vehicle body. After cleaning the mounting holes, they use bolts and other fasteners to lock the guide rail to the vehicle body point by point. During the locking process, it is also necessary to repeatedly calibrate the levelness and straightness of the guide rail. For some models, the guide rail is directly welded to the vehicle body. After welding, the weld is ground and treated with rust prevention. After the guide rail is fixed, the installers insert the sliding component into the slide groove of the guide rail. Then, using power tools or hand tools, they lock the upper edge of the glass to the sliding component point by point. After adjusting the gap between the glass and the vehicle body, the glass assembly is completed. During the assembly process, a sealing strip or sealant needs to be added between the contact surfaces of the guide rail and the vehicle body to fill the gaps caused by drilling and locking. In subsequent maintenance or glass replacement, the glass and sliding component need to be disassembled first, and then the fasteners need to be unscrewed one by one before the guide rail can be removed from the vehicle body.

[0004] The above installation method has gradually revealed the following defects during use: Drilling holes in the vehicle body weakens the local structural strength of the vehicle body and also adversely affects the sealing and corrosion resistance of the vehicle body; when fixed by welding, the guide rail cannot be disassembled, and when the guide rail is damaged or the glass is replaced, it can only be removed destructively, making maintenance very difficult; locking the guide rail and assembling the glass both require tools, resulting in many assembly steps, long assembly time, and high labor costs; the position of the fasteners is fixed after drilling, and the installation position of the guide rail in the length direction cannot be adjusted, making it difficult to adapt to glass of different widths; the support and guiding structure of the sliding component in the slide groove is simple, and the glass is prone to shaking and jamming during sliding, affecting the smoothness of glass opening and closing; the gap between the glass and the vehicle body relies on the experience of the assembly personnel for on-site adjustment, resulting in inconsistent assembly quality between different batches and affecting the consistency of the overall vehicle assembly; the fasteners are prone to loosening after long-term exposure to glass loads and vehicle vibrations, and the fixing reliability of the guide rail decreases with the use time, requiring regular shutdown and maintenance.

[0005] Therefore, those skilled in the art are dedicated to providing a tool-free installation method for glass guide rails in transportation equipment, which can effectively solve the above-mentioned technical problems. Summary of the Invention

[0006] According to a first aspect of the embodiments of this specification, a tool-free installation upper guide rail for the glass of a transportation equipment is provided, including an upper guide rail assembly, a sliding assembly, a snap-fit ​​assembly, a positioning seat, and a snap-fit ​​engagement assembly;

[0007] The upper guide rail assembly includes a guide rail body, on which a guide groove extending along the length of the guide rail body is formed;

[0008] Several sliding components are provided, and each of the sliding components can be slidably mounted on the guide rail body for installing glass;

[0009] The snap-fit ​​assembly is located at the rear end of the guide rail body; the positioning seat is installed on the transportation equipment.

[0010] The snap-fit ​​assembly is located on the outside of the positioning seat. The snap-fit ​​assembly engages with the snap-fit ​​assembly to fix the guide rail body to the transportation equipment without tools.

[0011] In one possible implementation, the guide rail body has an L-shaped cross-section and includes a vertical section and a horizontal section. The vertical section and the horizontal section are integrally formed. The lower end of the vertical section is connected to one side of the horizontal section, and two guide grooves are formed at the upper end of the horizontal section.

[0012] In one possible implementation, each guide chute includes a suspended section and a connecting section. The lower end of the suspended section is located directly above the horizontal section. The lower end of the suspended section is provided with two U-shaped guide grooves. The upper end of the connecting section is flush with the upper end of the suspended section, and the lower end of the connecting section is higher than the lower end of the suspended section. The connecting section has several connecting holes along its length direction. The connecting section is detachably connected to the upper end of the vertical section through several connecting holes.

[0013] In one possible implementation, at least two sliding components are provided, and the at least two sliding components are used to fix a piece of glass; the sliding component includes a sliding base, and positioning holes are provided at the four corners of the front end face of the sliding base. The positioning holes are used to install positioning clamping components, and the positioning clamping components are connected to the glass.

[0014] In one possible implementation, guide wheels are rotatably provided at the four corners of the upper end of the sliding seat. The guide wheels are located in guide grooves and cooperate with the guide grooves. The rotation axis of the guide wheels extends in the vertical direction. The guide wheels on both sides protrude from the sides of the sliding seat to prevent the sliding seat from wobbling left and right during sliding.

[0015] In one possible implementation, the lower end of the sliding seat has four mounting slots, and two guide pulleys are slidably installed in each mounting slot. Each guide pulley is located at a guide groove, and the guide groove guides the guide pulleys.

[0016] In one possible implementation, the snap-fit ​​assembly includes an installation section, a connecting plate, and a hanging section. The installation section is detachably connected to the vertical section. The inner side of the installation section is provided with a first limiting part integrally formed with the installation section. The cross-section of the first limiting part is semi-circular. The upper end of the installation section is connected to the upper end of the hanging section through the connecting plate. The hanging section extends downward. The installation section and the hanging section are arranged parallel to each other. The installation section, the hanging section, and the connecting plate are integrally formed. The inner side of the upper half of the hanging section is provided with a second limiting part. The second limiting part has the same structure as the first limiting part. The second limiting part and the first limiting part are offset. The second limiting part is located above the first limiting part. Both the first limiting part and the second limiting part are located between the installation section and the hanging section. The lower end of the hanging section is lower than the first limiting part and higher than the lower end of the installation section. The lower end of the hanging section has several positioning grooves, which are evenly distributed along the length direction of the hanging section.

[0017] In one possible implementation, the snap-fit ​​assembly includes two support pillars, a snap-fit ​​frame, a reinforcing member, and two insertion pins. The lower half of each support pillar has a fixing hole. A snap-fit ​​frame is positioned above the two support pillars, comprising a connecting part and a snap-fit ​​part. The lower end of the connecting part connects to the upper ends of both support pillars, and the connecting part and snap-fit ​​part are integrally formed. The lower end of the snap-fit ​​part connects to one side of the connecting part. A reinforcing member is positioned at the angle between the snap-fit ​​frame and the support pillars, connecting the two support pillars. Two insertion pins are positioned at the upper end of the connecting part, with the cross-section of each insertion pin gradually decreasing from the middle to the upper end. A first limiting groove is formed on the outer side of the snap-fit ​​part, and a second limiting groove is formed on the inner side of the snap-fit ​​part. The first and second limiting grooves are offset, with the second limiting groove positioned above the first limiting groove.

[0018] In one possible implementation, an auxiliary locking assembly and a locking engagement assembly are also included. The auxiliary locking assembly includes a slider and a slide rail. The slide rail is located at the lower end of the horizontal section, and the slider is slidably connected to the slide rail. The slider can reciprocate along the slide rail towards the positioning seat. The slider includes a sliding part, a guide section, and two deformable parts. The upper end of the guide section is connected to the sliding part, and the cross-section of the guide section gradually decreases from top to bottom. The two deformable parts are symmetrically arranged at the lower end of the guide section, forming a locking area between the two deformable parts. The locking engagement assembly is connected to the positioning seat and includes a positioning post, two elastic return members, and two swing limit members. The positioning post is locked into the locking area. The two elastic return members are respectively located on both sides of the positioning post and are S-shaped. The two swing limit members are respectively located above the two elastic return members. Both swing limit members are rotatably connected to the locking engagement assembly via a rotating shaft and are used in conjunction with the guide section.

[0019] According to a second aspect of the embodiments of this specification, a tool-free method for installing a guide rail on the glass of a transportation device is provided, comprising the following steps:

[0020] The connecting section of the guide slide is detachably connected to the upper end of the vertical section through several connecting holes. The guide pulley of the sliding seat is embedded in the guide slide, and the guide pulley is embedded in the U-shaped guide groove set at the lower end of the suspended section, so that the sliding seat can slide along the length direction of the guide rail body.

[0021] The snap-fit ​​assembly located at the rear end of the vertical section is hung on the snap-fit ​​part of the snap-fit ​​bracket of the snap-fit ​​mating assembly located outside the positioning seat. During the hanging process, the snap-fit ​​part is located between the installation section and the hanging section.

[0022] As the snap-fit ​​component continues to move downward, the first limiting part and the second limiting part deform under pressure and then snap into the first limiting groove and the second limiting groove respectively, thereby limiting the snap-fit ​​component through the first limiting part and the second limiting part;

[0023] When the snap-fit ​​assembly moves downward into place, the insertion post located at the upper end of the connecting part is in the positioning groove, which limits the snap-fit ​​assembly in all directions, thereby fixing the guide rail body to the transportation equipment without tools.

[0024] The sliding part of the sliding component is pushed to slide along the slide rail towards the positioning seat. The positioning post of the locking assembly is engaged in the engagement area between the two deformable parts. The two deformable parts are located below the two swing limiters. The guide section presses the two swing limiters, causing the two swing limiters to rotate around the pivot and press the elastic return member. After the two swing limiters are reset, they limit the two deformable parts respectively, locking the upper guide rail assembly on the positioning seat.

[0025] The positioning clamping assembly is installed at the front end of the sliding seat through the positioning hole, and the glass is installed on the sliding seat through the positioning clamping assembly. The sliding seat is pushed to slide along the length direction of the guide rail body, and the guide pulley rolls in the guide groove, so that the glass slides along the length direction of the guide rail body.

[0026] As described above, the present invention provides a tool-free installation guide rail for the glass of transportation equipment and an installation method thereof, which has the following beneficial effects:

[0027] 1. This invention uses a snap-fit ​​component to engage with a snap-fit ​​mating component, which fixes the upper guide rail component onto the positioning seat without tools, and the entire installation and disassembly process requires no tools;

[0028] 2. The snap-fit ​​fixing method in this invention does not require drilling holes in the vehicle body, does not damage the structural strength of the vehicle body, helps to maintain the sealing and anti-corrosion performance of the vehicle body, and extends the service life of transportation equipment;

[0029] 3. In this invention, the first limiting part is inserted into the first limiting groove, and the second limiting part is inserted into the second limiting groove. The first limiting part and the second limiting part are arranged vertically and vertically, and are inserted into the positioning groove with the plug-in post. This forms a limiting on the upper guide rail assembly in the vertical, front-back and left-right directions. The multiple limitings are independent of each other and serve as backups for each other. The upper guide rail assembly is firmly fixed and the glass is installed stably.

[0030] 4. In this invention, the lower end of the hanging section is evenly distributed with several positioning grooves along the length direction. The insertion post can be selected to be aligned and inserted into any positioning groove according to the width of the glass. The hanging position of the upper guide rail assembly in the length direction can be adjusted as needed to adapt to glass of different widths.

[0031] 5. In this invention, the guide wheel at the upper end of the sliding seat is embedded in the guide groove, which restricts the horizontal displacement of the guide wheel. The guide pulley at the lower end of the sliding seat is embedded in the guide groove to roll and bear the load. The upper guide and the lower guide cooperate with each other, so that the glass sliding process is smooth and stable, and it is not easy to shake or jam.

[0032] 6. In this invention, the first and second limiting parts of the deformable material are deformed and displaced under pressure. After the extrusion disappears, they automatically spring back to their original position. The snap-fit ​​part can be pressed down to snap into place and lifted up to disengage. Repeated disassembly and assembly will not damage the limiting structure. The snap-fit ​​is durable.

[0033] 7. The sliding member in this invention can make the positioning post engage in the engagement area. The swing limiting member is reset and stops the deformation under the restoring force of the elastic return member, forming a push-in secondary lock. The locking of the upper guide rail assembly is further reinforced. When unlocking, press the swing limiting member and pull the sliding member outward to separate. Locking and unlocking also do not require tools.

[0034] 8. The reinforcing member in this invention connects two support columns simultaneously, which reinforces the connection angle between the snap-fit ​​frame and the support column, improves the bending resistance of the snap-fit ​​assembly, and makes it less prone to deformation and loosening under long-term load.

Detailed Implementation

[0053] The present invention will be further described below with reference to the accompanying drawings and embodiments:

[0054] In the description of this invention, it should be noted that the terms "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing the invention and for simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the invention. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0055] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "setting," and "connection" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0056] This specification provides a tool-free installation method for the upper guide rail of a transportation equipment glass. The following embodiments will be described in detail.

[0057] This embodiment provides a tool-free installation guide rail for the glass of a transportation device, referring to... Figures 1 to 16 The system includes an upper guide rail assembly 100, a sliding assembly 200, a snap-fit ​​assembly 300, a positioning seat 500, a snap-fit ​​mating assembly 600, an auxiliary snap-fit ​​assembly 700, and a locking mating assembly 750. The upper guide rail assembly 100 is used to install glass 1000 along its length. The snap-fit ​​assembly 300 is located at the rear end of the upper guide rail assembly 100. The positioning seat 500 is mounted on the transportation equipment and is located behind the upper guide rail assembly 100. The snap-fit ​​mating assembly 600 is located outside the positioning seat 500, and the snap-fit ​​assembly 300 engages with the snap-fit ​​mating assembly 600. The auxiliary snap-fit ​​assembly 700 engages with the locking mating assembly 750 to lock the upper guide rail assembly 100 onto the positioning seat 500.

[0058] During installation, the operator can easily mount and fix the upper guide rail assembly 100 onto the positioning seat 500 without using any tools or drilling holes in the vehicle body. The glass 1000 can then be installed onto the upper guide rail assembly 100, avoiding the damage to the vehicle structure caused by traditional drilling methods. This ensures the structural strength of the transportation equipment itself and extends its service life. Furthermore, after installation, the glass 1000 can slide smoothly along the length of the upper guide rail assembly 100, maintaining stability and reliability without lateral wobbling.

[0059] The specific structure of this embodiment will be described in detail below.

[0060] The upper guide rail assembly 100 includes a guide rail body 101 with an L-shaped cross-section. The guide rail body 101 includes a vertical section 101a and a horizontal section 101b. The lower end of the vertical section 101a is connected to one side of the horizontal section 101b, and the vertical section 101a and the horizontal section 101b are integrally formed. Specifically, the horizontal section 101b extends horizontally, and the vertical section 101a extends vertically upward from the upper surface of the horizontal section 101b. Together, they form an integral profile structure with an L-shaped cross-section, which is easy to integrally form through extrusion, resulting in low processing costs and high overall structural strength.

[0061] It can be seen that the L-shaped integrally formed guide rail body 101 has a vertical section 101a that is arranged to correspond with the side structure of the vehicle body and supports the snap-fit ​​component 300, and a horizontal section 101b that supports the sliding component 200. The upper guide rail component 100 only needs one profile to complete the construction of the main load-bearing structure, the assembly foundation is stable, and the cumulative error caused by the assembly of multiple parts is eliminated.

[0062] In one possible implementation, refer to Figure 1 Two guide grooves 102 extending along the length of the guide rail body 101 are provided at the upper end of the horizontal section 101b. That is, the guide grooves 102 are located directly above the horizontal section 101b, and the two guide grooves 102 extend parallel to each other along the length of the guide rail body 101. Figure 1 The diagram shows the segmentation of the guide groove 102 along its length: the section located on the side near the snap-fit ​​assembly 300 is the connecting section 102b. Figure 1 The section on the other side is marked 102b; the section on the other side is the suspended section 102a. Figure 1 It is marked with 102a.

[0063] Reference Figure 1 and Figure 7 The guide chute 102 includes a suspended section 102a and a connecting section 102b. The lower end of the suspended section 102a is located directly above the horizontal section 101b. The lower end of the suspended section 102a is provided with two U-shaped guide grooves 103. The upper end of the connecting section 102b is flush with the upper end of the suspended section 102a, and the lower end of the connecting section 102b is higher than the lower end of the suspended section 102a. The connecting section 102b is provided with a number of connecting holes 102c along its length direction. The connecting section 102b is detachably connected to the upper end of the vertical section 101a through the number of connecting holes 102c.

[0064] Specifically, in combination Figure 7 and Figure 9 , Figure 7 An enlarged view of the connection between the vertical section 101a, the horizontal section 101b, and the guide groove 102 is shown. Figure 9The three-dimensional structure of connecting segment 102b is shown. Connecting holes 102c are provided on the plate of connecting segment 102b, and several connecting holes 102c are spaced apart along the length of connecting segment 102b. A serrated positioning structure with mutual engagement is provided between the lower edge of connecting segment 102b and the upper end of vertical segment 101a. During installation, the serrated positioning structure is first engaged and aligned, and then fasteners are inserted through the connecting holes 102c and locked to vertical segment 101a, thus achieving a detachable connection between connecting segment 102b and vertical segment 101a. The serrated positioning structure serves to provide circumferential positioning and prevent misalignment, making it difficult for connecting segment 102b to shift during locking, ensuring reliable connection and convenient assembly and disassembly.

[0065] In one possible implementation, the connecting hole 102c can be either an oblong hole or a round hole. When the connecting hole 102c is an oblong hole, the connecting section 102b has a small position adjustment margin before locking, which facilitates alignment during assembly. The specific form can be determined according to the processing technology and installation accuracy requirements.

[0066] The lower end of the suspended section 102a is provided with two U-shaped guide grooves 103, which extend along the length of the guide groove 102 and are spaced apart from each other. Figure 2 , Figure 2 The diagram shows a partially enlarged fit between the guide groove 103 and the sliding assembly 200. The U-shaped guide groove 103 covers the guide wheel 203 at the upper end of the sliding assembly 200 from the outside, providing a horizontal limit for the guide wheel 203. The lower end of the suspended section 102a is suspended, creating a sliding space below the guide groove 102 for the upper end of the sliding assembly 200 to extend into. During the sliding process, the guide wheel 205 at the lower end of the sliding assembly 200 rolls and guides along the guide groove 102, while the guide wheel 203 at the upper end rolls and limits along the guide groove 103. The simultaneous guidance from both ends ensures the smoothness and straightness of the sliding assembly 200 as it slides along the length of the guide rail body 101.

[0067] In one possible implementation, it is preferable to have two guide grooves 103, with the two guide grooves 103 respectively corresponding to the two guide wheels 203 at the upper end of the sliding component 200; the guide grooves 103 and the guide slide 102 are integrally formed structures, or they can be separate structures, which are not specifically limited here.

[0068] Therefore, it can be seen that the guide slide 102 decouples the sliding guiding function from the installation and connection function through the segmented arrangement of the suspended section 102a and the connecting section 102b: the suspended section 102a is responsible for providing a stable sliding guiding space for the sliding component 200, and the connecting section 102b is responsible for detachably fixing the entire guide slide 102 to the vertical section 101a, and the two do not interfere with each other; at the same time, the detachable connection method allows the guide slide 102 to be replaced separately after wear, without having to scrap the entire guide rail body 101, thus reducing maintenance costs;

[0069] Reference Figure 3 and Figure 8 The number of sliding components 200 is several, and the several sliding components 200 can be slidably arranged on the upper guide rail assembly 100 and can slide along the length direction of the upper guide rail assembly 100. Figure 3 The overall assembly structure of the upper guide rail assembly 100 and multiple sliding assemblies 200 is shown. Figure 8 The diagram shows the state in which the glass 1000 is suspended on the upper guide rail assembly 100. The number of sliding assemblies 200 is determined according to the length of the guide rail and the number of glass 1000 in actual use. Each glass 1000 corresponds to at least two sliding assemblies 200, that is, at least two sliding assemblies 200 are used to fix one glass 1000 to ensure that the glass 1000 is subjected to uniform force and suspended stably.

[0070] In one possible implementation, refer to Figure 5 The sliding assembly 200 includes a sliding base 201. Positioning holes 202 are provided at each of the four corners of the front end of the sliding base 201. The positioning holes 202 are used to install a positioning clamping assembly, which is connected to the glass 1000 to position and fix the glass 1000. The positioning clamping assembly is not the main improvement of this solution; it is existing technology. Any existing structure capable of achieving glass positioning and clamping can be used, such as a clamping structure combining a pressure plate and fasteners, or a snap-on clamping structure. The specific choice depends on the thickness, weight, and cost requirements of the glass 1000, and will not be elaborated here.

[0071] Combination Figure 8 The upper end of the glass 1000 extends between the sliding seat 201 and the positioning clamping assembly. The positioning clamping assembly is fixed to the front end of the sliding seat 201 through the positioning hole 202, clamping and positioning the upper edge of the glass 1000, thereby suspending the glass 1000 on the upper guide rail assembly 100. Since at least two sliding assemblies 200 jointly support a piece of glass 1000, the weight of the glass 1000 is distributed and the force at a single point is small, making it less prone to deformation and detachment during long-term use.

[0072] In one possible implementation, refer to Figure 2 and Figure 5The upper end of the sliding seat 201 is provided with guide wheels 203 at each of its four rotatable corners. The four guide wheels 203 are respectively located within guide grooves 103 and cooperate with the guide grooves 103. Figure 2 The rotation axis of the guide wheel 203 extends in the vertical direction, that is, the guide wheel 203 can rotate freely around the vertical axis; the part of the structure of the guide wheel 203 located on both sides protrudes from the side of the sliding seat 201, and the protruding part rolls against the side wall of the guide groove 103, thereby preventing the sliding seat 201 from wobbling left and right, and making the sliding seat 201 slide more smoothly.

[0073] Specifically, refer to Figure 5 , Figure 5 for Figure 4 The enlarged view of the area marked with b shows the three-dimensional structure of the sliding seat 201. A guide wheel 203 is provided at each of the four corners of the upper end of the sliding seat 201. The guide wheels 203 are rotatably connected to the sliding seat 201 via a rotating shaft extending vertically. The fitting relationship between the guide wheels 203 and the guide groove 103 is shown in [reference needed]. Figure 2 The guide wheel 203 is inserted into the U-shaped guide groove 103. The two side arms of the guide groove 103 are respectively limited to the two sides of the guide wheel 203. The guide wheel 203 rolls along the length of the guide groove 103. It cannot come out of the guide groove 103 to the left or right, nor can it swing in the horizontal plane. The horizontal posture of the sliding seat 201 during the sliding process is completely constrained, and the glass 1000 will not sway left or right with the sliding seat 201.

[0074] In one possible implementation, refer to Figure 6 The lower end of the sliding seat 201 is provided with several mounting slots 206. There are four mounting slots 206. Two guide pulleys 205 can be slidably arranged in each mounting slot 206. Each guide pulley 205 is located at a guide groove 102 and is guided by the guide groove 102. Figure 6 The structure of the bottom surface of the sliding seat 201 is shown. Four mounting slots 206 are arranged in two groups in the four corner areas at the lower end of the sliding seat 201. Two guide pulleys 205 are arranged side by side in each mounting slot 206. The guide pulleys 205 are embedded in the guide groove 102 and can roll along the guide groove 102. The groove wall of the mounting slot 206 limits the guide pulleys 205 to prevent them from falling out.

[0075] It can be seen that the sliding component 200 forms a double-guide structure by cooperating with the upper guide wheel 203 and the guide groove 103, and with the lower guide pulley 205 and the guide groove 102. The upper guide wheel 203 is responsible for limiting and preventing swaying in the horizontal direction, and the lower guide pulley 205 is responsible for bearing the weight and guiding in the length direction. The sliding component 200 can still slide smoothly and easily along the length direction of the guide rail body 101 when the glass 1000 is fully loaded. It has good sliding stability and saves effort and has no play when the user pushes and pulls the glass 1000.

[0076] In one possible implementation, the number of mounting slots 206 and the number of guide pulleys 205 in each mounting slot 206 can be increased or decreased according to the size of the sliding seat 201 and the load requirements. For example, when the glass 1000 is heavy, the number of mounting slots 206 or the number of guide pulleys 205 in each mounting slot 206 can be increased to distribute the wheel pressure and reduce the wear of a single wheel. The specific implementation can be determined according to the actual use.

[0077] In one possible implementation, refer to Figure 1 , Figure 10 and Figure 14 The upper guide rail assembly 100 is provided with a snap-fit ​​component 300 at its rear end, that is, the snap-fit ​​component 300 is provided at the rear end of the vertical section 101a. The snap-fit ​​component 300 is approximately the same length as the guide rail body 101, and both ends of the snap-fit ​​component 300 are flush with both ends of the guide rail body 101, so that the snap-fit ​​component 300 is evenly stressed along the entire length of the guide rail body 101, and the upper guide rail assembly 100 is less likely to warp locally after installation.

[0078] Reference Figure 10 , Figure 11 and Figure 15 The snap-fit ​​assembly 300 includes a mounting section 301, which is detachably connected to the vertical section 101a. Specifically, in conjunction with Figure 10 The mounting section 301 is attached to the rear side of the vertical section 101a. The mounting section 301 is detachably connected to the vertical section 101a by fasteners. Its connection method is independent of and does not interfere with the connection methods of the connecting section 102b and the vertical section 101a. Figure 10 The image also shows the slide rail 702 located at the lower end of the horizontal section 101b and a magnified area c at the lower right end.

[0079] The inner side of the mounting section 301 is provided with a first limiting part 302 integrally formed with the mounting section 301, and the cross-section of the first limiting part 302 is semi-circular. Figure 11 , Figure 11 for Figure 10 In the enlarged view of part c, the first limiting part 302 protrudes from the inner surface of the mounting section 301 toward the inner cavity of the snap-fit ​​assembly 300, forming a semi-circular protrusion structure.

[0080] Reference Figure 11 and Figure 15 The upper end of the mounting section 301 is connected to the upper end of the hanging section 305 via a connecting plate 303. The hanging section 305 extends downwards, and the mounting section 301 and the hanging section 305 are arranged parallel to each other. The mounting section 301, the hanging section 305, and the connecting plate 303 are integrally formed structures. Specifically, in conjunction with Figure 15 , Figure 15The connection details between the upper end of the mounting section 301 and the hook section 305 are shown. The connecting plate 303 is placed horizontally between the upper ends of the mounting section 301 and the hook section 305, connecting the two into one. The hook section 305 extends downward from the connecting plate 303, and is parallel and spaced from the mounting section 301. A cavity area is formed between the mounting section 301 and the hook section 305 for the snap-fit ​​portion of the snap-fit ​​assembly 600 to extend into.

[0081] In one possible implementation, a second limiting part 306 is provided on the inner side of the upper half of the connecting section 305. The second limiting part 306 has the same structure as the first limiting part 302, that is, the second limiting part 306 is also a protruding structure with a semi-circular cross-section. The second limiting part 306 is offset from the first limiting part 302, and the second limiting part 306 is located above the first limiting part 302. Figure 11 The first limiting part 302 protrudes from the inner side of the mounting section 301, and the second limiting part 306 protrudes from the inner side of the hook section 305. The two are staggered in the height direction, so that the snap-fit ​​part is blocked and guided by the first limiting part 302 and the second limiting part 306 in turn as it enters the cavity area from above.

[0082] In one possible implementation, both the first limiting part 302 and the second limiting part 306 are located between the mounting section 301 and the hooking section 305. The lower end of the hooking section 305 is lower than the first limiting part 302 and higher than the lower end of the mounting section 301. That is, the length of the hooking section 305 is shorter than that of the mounting section 301, and a clearance space is formed between the lower end of the hooking section 305 and the lower end of the mounting section 301.

[0083] Reference Figure 15 The lower end of the connecting section 305 is provided with several positioning grooves 307. The several positioning grooves 307 are opened at the lower end of the connecting section 305 and are evenly distributed along the length of the connecting section 305. Figure 15 The image shows serrated positioning grooves 307 arranged along the length of the lower edge of the hook section 305, with equal spacing between adjacent positioning grooves 307.

[0084] In one possible implementation, both the first limiting part 302 and the second limiting part 306 are made of deformable materials, such as elastic engineering plastics or elastic metal sheets. The specific material used depends on the magnitude of the clamping force and cost requirements. By using deformable materials, the first limiting part 302 and the second limiting part 306 can elastically deform and reposition themselves when compressed, and automatically spring back to their original position after the compression disappears, thus achieving tool-free insertion and removal.

[0085] Thus, it can be seen that the snap-fit ​​assembly 300 forms an open snap-fit ​​cavity by the mounting section 301, the hanging section 305 and the connecting plate 303. The first limiting part 302 and the second limiting part 306 are staggered vertically in the cavity. The positioning groove 307 is evenly distributed along the entire length of the hanging section 305, so that the snap-fit ​​assembly 300 has both the hanging load capacity and the multi-limiting cooperation basis with the snap-fit ​​mating assembly 600. At the same time, the even distribution of the positioning groove 307 also allows the hanging position of the snap-fit ​​assembly 300 in the length direction to be selected as needed, adapting to glass 1000 of different widths and guide rails of different lengths.

[0086] Reference Figure 1 and Figure 12 The positioning seat 500 is installed on the transportation equipment. Once fixed, the positioning seat 500 does not need to be disassembled. The positioning seat 500 can be regarded as being welded and fixed to the transportation equipment as a whole. The outer side of the positioning seat 500 is provided with a snap-fit ​​component 600. The snap-fit ​​component 600 and the snap-fit ​​component 300 are used to snap together. The upper guide rail component 100 is hung on the snap-fit ​​component 600 through the snap-fit ​​component 300 located at the rear end of the vertical section 101a, thereby fixing the upper guide rail component 100.

[0087] Combination Figure 12 , Figure 12 The overall assembly structure of the positioning seat 500 and the snap-fit ​​assembly 600 is shown. The positioning seat 500 is a long strip plate. Multiple snap-fit ​​assemblies 600 are distributed along the length of the positioning seat 500. Each snap-fit ​​assembly 600 corresponds to a snap-fit ​​assembly 300. That is, each snap-fit ​​assembly 600 is used to cooperate with the snap-fit ​​assembly 300 on an upper guide rail assembly 100 to meet the requirement of multiple glass panels 1000 being installed side by side on transportation equipment.

[0088] In one possible implementation, refer to Figure 13 The snap-fit ​​assembly 600 includes two support posts 601, each with a fixing hole 602 in its lower half. Figure 13 and Figure 14 The fixing hole 602 can be an oblong hole, with the long axis of the oblong hole extending vertically. By inserting fasteners through the fixing hole 602, the two support columns 601 can be fixed to the positioning seat 500. The oblong hole facilitates the fine adjustment of the installation position of the snap-fit ​​component 600 in the height direction, ensuring that the height of the snap-fit ​​part is accurately aligned with the snap-fit ​​component 300. A round hole can also be used, depending on the installation accuracy requirements.

[0089] Reference Figure 13A snap-fit ​​bracket 603 is provided above the two support columns 601. The snap-fit ​​bracket 603 includes a connecting part 603a and a snap-fit ​​part 603b. The lower end of the connecting part 603a is connected to the upper end of both support columns 601. The connecting part 603a and the snap-fit ​​part 603b are integrally formed. The lower end of the snap-fit ​​part 603b is connected to one side of the connecting part 603a. Specifically, in conjunction with Figure 13 The connecting part 603a extends horizontally and is erected between the upper ends of the two support columns 601. The snap-fit ​​part 603b extends vertically upward from one side of the connecting part 603a. The snap-fit ​​part 603b and the two support columns 601 are located on opposite sides of the connecting part 603a. The snap-fit ​​part 603b, the connecting part 603a and the two support columns 601 together form a stable load-bearing frame.

[0090] Reference Figure 13 and Figure 14 A reinforcing member 605 is provided at the angle between the clip bracket 603 and the support column 601, and the reinforcing member 605 connects the two support columns 601. Figure 13 The reinforcing member 605 is in the shape of an arc plate, bridging the corner area between the snap-fit ​​part 603b and the connecting part 603a and the two support columns 601. It forms a triangular reinforcement for the connection angle between the snap-fit ​​frame 603 and the support column 601, which significantly improves the bending stiffness and impact resistance of the snap-fit ​​assembly 600, and ensures that the snap-fit ​​assembly 600 does not deform or loosen under repeated mounting and dismounting and long-term load of the glass 1000.

[0091] Reference Figure 13 The upper end of the connecting part 603a is also provided with two insertion posts 606, the cross-section of which gradually decreases from the middle to the upper end. Specifically, the two insertion posts 606 are arranged at intervals along the length direction of the connecting part 603a. The lower part of the insertion post 606 is fixedly connected to the connecting part 603a, and the outer contour gradually tapers from the middle to the upper end to form a guide cone surface. The upper end of the insertion post 606 is smoothly transitioned, which facilitates the insertion post 606 to be smoothly inserted into the positioning groove 307 of the snap-fit ​​assembly 300, thereby limiting the snap-fit ​​assembly 300 in the length and thickness directions.

[0092] Reference Figure 13 The outer side of the latching part 603b is provided with a first limiting groove 608, and the inner side of the latching part 603b is provided with a second limiting groove 609. The first limiting groove 608 and the second limiting groove 609 are offset, with the second limiting groove 609 located above the first limiting groove 608. Figure 13The first limiting groove 608 is a semi-circular groove formed on the outer surface of the snap-fit ​​part 603b, and the second limiting groove 609 is a semi-circular groove formed on the inner surface of the snap-fit ​​part 603b. The two are staggered vertically in the height direction and are aligned one-to-one with the first limiting part 302 and the second limiting part 306 on the snap-fit ​​assembly 300: the first limiting part 302 is located inside the mounting section 301 and directly opposite the outer side of the snap-fit ​​part 603b, and is snapped into the first limiting groove 608; the second limiting part 306 is located inside the hanging section 305 and directly opposite the inner side of the snap-fit ​​part 603b, and is snapped into the second limiting groove 609.

[0093] Therefore, it can be seen that the snap-fit ​​component 300 and the snap-fit ​​mating component 600 achieve tool-free fixation through a triple mating of "hooking + double limiting + plug-in positioning": the snap-fit ​​part 603b extends into the mounting section 301 and the hook-fit section 305 to form a gravity hook-fit; the first limiting part 302 snaps into the first limiting groove 608 and the second limiting part 306 snaps into the second limiting groove 609 to form a double locking in the up and down direction and the separation direction; the plug-in post 606 inserts into the positioning groove 307 to form positioning in the length direction and the thickness direction. The limiting in each direction is independent and serves as a backup for each other. The failure of a single mating point will not cause the whole thing to detach. The fixation reliability is high, and no tools are required throughout the process.

[0094] In one possible implementation, refer to Figure 1 and Figure 16 The upper guide rail assembly 100 also includes an auxiliary snap-fit ​​assembly 700 and a locking engagement assembly 750. The auxiliary snap-fit ​​assembly 700 and the locking engagement assembly 750 cooperate to further lock the upper guide rail assembly 100 onto the positioning seat 500. Figure 1 and Figure 10 The slide rail 702 is located at the lower end of the horizontal section 101b and extends along the length of the guide rail body 101. The sliding member 701 is slidably connected to the slide rail 702 and can slide back and forth along the slide rail 702 toward the positioning seat 500. Figure 1 The diagram shows the arrangement of the slide rail 702 extending from the lower end of the horizontal section 101b toward the positioning seat 500, with the slider 701 and the locking engagement assembly 750 both located in the extended end region of the slide rail 702.

[0095] Reference Figure 16 The slider 701 includes a sliding part 701a, which is slidably connected to the slide rail 702. The sliding part 701a is the main bearing part of the slider 701, and its upper end cooperates with the slide rail 702.

[0096] A guide section 701b is provided at the lower end of the sliding part 701a. The upper end of the guide section 701b is connected to the sliding part 701a. The cross-section of the guide section 701b gradually decreases from top to bottom, that is, the outer contour of the guide section 701b contracts from top to bottom, forming a guide slope. Figure 16 , Figure 16 This is an enlarged cross-sectional view of the mating point between the slider 701 and the locking assembly 750. The guide section 701b is located directly below the slider 701a, and its two inclined surfaces converge from top to bottom towards the middle.

[0097] The lower end of the guide section 701b is provided with two symmetrically deformable portions 701c, and a snap-fit ​​area 701d is formed between the two deformable portions 701c. Figure 16 Two deformable portions 701c bend downwards from both sides of the lower end of the guide section 701b, arranged symmetrically. The space between the two deformable portions 701c is the locking area 701d, which is used to accommodate the positioning post 751 of the locking assembly 750. The deformable portions 701c are made of elastic material, which can expand and deform outwards when compressed, and automatically spring back and retract after the compression is removed.

[0098] Reference Figure 16 The locking engagement component 750 is connected to the positioning seat 500. The locking engagement component 750 includes a positioning post 751, which engages with the locking area 701d. Figure 1 The locking assembly 750 is located at the end of the slide rail 702 in the extending direction, near the positioning seat 500; [The text abruptly ends here, likely due to an incomplete sentence or missing information.] Figure 16 The positioning post 751 has a circular cross-section, and the main body of the self-locking fitting assembly 750 protrudes upward, directly opposite the snap-fit ​​area 701d between the two deformable parts 701c.

[0099] Two elastic return members 752 are provided on both sides of the positioning post 751, and each elastic return member 752 has an S-shaped structure. Combined with... Figure 16 Two S-shaped elastic return members 752 are placed on the left and right sides of the positioning post 751. The S-shaped bending profile gives it a long effective elastic deformation stroke in a small installation space.

[0100] Above each of the two elastic return members 752 is a swing limit member 753. There are two swing limit members 753, which are rotatably connected to the locking assembly 750 via a rotating shaft 755. The swing limit members 753 cooperate with the guide section 701b. Figure 16Two swing limiters 753 are placed on the left and right sides of the guide section 701b. Each swing limiter 753 has a pivot hole. The pivot 755 passes through the pivot hole and is fixed on the locking assembly 750. The swing limiter 753 can swing around the pivot 755. Its free end is held in the downward swing position by its own weight or the elastic restoring force of the elastic return member 752.

[0101] In one possible implementation, the elastic return member 752 can be made of spring steel sheet bent into an S-shape, or it can be made of elastic engineering plastic injection molding, or it can be made of torsion spring. The specific form can be determined according to the locking force requirements and cost. The swing limit member 753 is made of rigid plastic plate or metal plate. On the side facing the guide section 701b, there is a guide slope that matches the slope of the guide section 701b, so that the swing limit member 753 can be smoothly squeezed open when the guide section 701b moves down. No specific limitation is made here.

[0102] Therefore, the sliding member 701 and the locking engagement assembly 750 constitute a purely mechanical push-in secondary locking mechanism: when the sliding member 701 is pushed in, the positioning post 751 opens the two deformable parts 701c to enter the locking area 701d to complete the locking. The inclined surface of the guide section 701b presses the two swing limit members 753 to make them swing around the rotating shaft 755 to make room. When the swing limit members 753 swing, they press the elastic return member 752 to store energy. After the sliding member 701 is in place, the swing limit members 753 are reset under the restoring force of the elastic return member 752, blocking the two deformable parts 701c from below, so that the sliding member 701 can neither move backward nor upward, and the locking state is stable. When unlocking, it is only necessary to press the two swing limit members 753 and pull the sliding member 701 outward. The deformable parts 701c elastically deform to make room for the positioning post 751, and the sliding member 701 can be pulled out. No tools are required throughout the process.

[0103] Reference Figures 1 to 16 This embodiment also provides a tool-free installation method for the upper guide rail of the glass of transportation equipment, which is implemented using the above-mentioned tool-free installation method for the upper guide rail of the glass of transportation equipment. The installation method includes the following steps:

[0104] S1. Assemble the upper guide rail assembly 100 and the sliding assembly 200: detachably connect the connecting section 102b to the upper end of the vertical section 101a through several connecting holes 102c, thus fixing the guide groove 102 in place; embed the guide pulley 205 of each sliding assembly 200 into the corresponding guide groove 102, so that each guide pulley 205 is positioned at its respective guide groove 102 for guidance; simultaneously embed the guide wheel 203 at the upper end of each sliding assembly 200 into the corresponding guide groove 103, thus completing the sliding assembly of the sliding assembly 200 on the upper guide rail assembly 100.

[0105] S2. Mounting the upper guide rail assembly 100: Move the snap-fit ​​assembly 300 at the rear end of the upper guide rail assembly 100 toward the snap-fit ​​mating assembly 600 outside the positioning seat 500, so that the upper end of the snap-fit ​​part 603b enters the cavity area between the installation section 301 and the hanging section 305 from above, and continue to lower it so that the snap-fit ​​part 603b is located between the installation section 301 and the hanging section 305. At this time, the weight of the upper guide rail assembly 100 is transferred to the two support columns 601 through the snap-fit ​​part 603b and the connecting part 603a, and then to the positioning seat 500 to achieve suspension bearing.

[0106] S3. Double Limit Locking: During the downward movement of the locking part 603b, the outer wall of the locking part 603b presses against the first limiting part 302, causing the deformable material of the first limiting part 302 to deform and move out of place. After the locking part 603b passes the first limiting part 302, the first limiting part 302 springs back and locks into the first limiting groove 608. At the same time, the inner wall of the locking part 603b presses against the second limiting part 306. After the second limiting part 306 is deformed and moves out of place, it springs back and locks into the second limiting groove 609. The first limiting part 302 and the second limiting part 306 respectively engage and limit with the first limiting groove 608 and the second limiting groove 609, preventing the locking part 603b from coming out upward.

[0107] S4. Insertion and positioning: After the upper guide rail assembly 100 is completely lowered, the two insertion posts 606 at the upper end of the connecting part 603a are inserted into the positioning grooves 307 at the corresponding positions at the lower end of the hanging section 305. The insertion posts 606 cooperate with the positioning grooves 307 to limit the locking assembly 300 in four directions: front, back, left, and right. At this time, the upper guide rail assembly 100 is fixed without tools through the locking assembly 300 and the locking engagement assembly 600.

[0108] S5. Secondary Locking: Push the sliding part 701a of the slider 701 along the slide rail 702 towards the positioning seat 500. The guide section 701b moves towards the positioning post 751. The tapered end of the positioning post 751 presses against the two deformable parts 701c, causing the two deformable parts 701c to open and deform outward. The positioning post 751 is engaged in the engagement area 701d between the two deformable parts 701c. Continue pushing, and the downward movement of the guide section 701b presses against the two swing limiters 753. The two swing limiters 753 rotate around the pivot 755 respectively. The rotating swing limiters 753 press the corresponding elastic return members 752, causing the elastic return members 752 to elastically deform and store energy. After the slider 701 reaches the locking position, the two swing limiters 753 swing back to their original positions under the restoring force of the elastic return members 752, limiting and blocking the two deformed parts 701c from below, preventing the slider 701 from exiting, thereby further locking the upper guide rail assembly 100 onto the positioning seat 500.

[0109] S6. Install glass 1000: Install the positioning clamping component at the front end of the sliding seat 201 through the positioning hole 202, extend the upper edge of glass 1000 between the positioning clamping component and the sliding seat 201 and clamp and fix it to complete the installation of glass 1000; After the glass 1000 is installed, push the glass 1000, and each sliding component 200 will slide smoothly along the length direction of the guide rail body 101 under the guiding action of the lower guide pulley 205 rolling in the guide groove 102 and the limiting action of the upper guide wheel 203 rolling in the guide groove 103, so as to realize the opening and closing adjustment of glass 1000.

[0110] In one possible implementation, in step S2, the operator can also select any one of the several positioning grooves 307 evenly distributed along the length direction at the lower end of the hanging section 305 to align with the plug-in post 606 according to the width requirements of the glass 1000, thereby fine-tuning the hanging position of the upper guide rail assembly 100 in the length direction; when unlocking in step S5, the two swing limiting members 753 are squeezed inward to make them swing around the rotating axis 755 and press the elastic return member 752, while the sliding member 701 is pulled outward. The two deformable parts 701c are stretched and elastically deformed and opened, and the positioning post 751 is disengaged from the snap-fit ​​area 701d, so that the sliding member 701 can be separated from the locking engagement assembly 750, which also does not require any tools.

[0111] Optimal working principle:

[0112] After installation, the working principle of the tool-free installation of the upper guide rail for the glass of the transportation equipment is as follows: The positioning seat 500 is pre-fixed on the transportation equipment and integrated with the main body of the transportation equipment. In the snap-fit ​​assembly 600 on the outside of the positioning seat 500, two support columns 601 are fastened to the positioning seat 500 through the fixing holes 602 in their respective lower halves. The connecting part 603a is mounted on the upper end of the two support columns 601 and integrated with them. The reinforcing member 605 bridges the two support columns 601 at the angle between the snap-fit ​​frame 603 and the support columns 601. The snap-fit ​​part 603b extends vertically upward from one side of the connecting part 603a, forming a stable load-bearing snap-fit ​​reference. In the upper guide rail assembly 100... The L-shaped guide rail body 101 is integrally formed from a vertical section 101a and a horizontal section 101b. Two guide grooves 102 are provided at the upper end of the horizontal section 101b. The suspended section 102a of the guide groove 102 is suspended, and two U-shaped guide grooves 103 are provided at its lower end. The connecting section 102b is aligned with a serrated positioning structure and locked to the upper end of the vertical section 101a through several connecting holes 102c. The mounting section 301 is detachably connected to the rear side of the vertical section 101a. The mounting section 301 is integrally connected to the upper end of the hanging section 305 via a connecting plate 303. The first limiting part 302 on the inner side of the mounting section 301 and the second limiting part 306 on the inner side of the hanging section 305 are vertically offset and both extend into the mounting section 301a. In the cavity area between the 1 and the hanging section 305, several positioning grooves 307 at the lower end of the hanging section 305 are evenly distributed along the length direction. During installation, the snap-fit ​​part 603b enters the cavity area from above. The first limiting part 302 and the second limiting part 306 are deformed and rebounded after being pressed, and then respectively snap into the first limiting groove 608 on the outside and the second limiting groove 609 on the inside of the snap-fit ​​part 603b, locking the snap-fit ​​part 603b in the vertical and disengagement directions. The two insertion pins 606 are simultaneously inserted into the corresponding positioning grooves 307, positioning the snap-fit ​​assembly 300 in the length and thickness directions. The upper guide rail assembly 100 is then fixed to the positioning seat 500 without tools. Subsequently, the slide rail at the lower end of the horizontal section 101b... The slider 701 on 702 is pushed toward the positioning seat 500. The sliding part 701a slides along the slide rail 702. The narrowing slope of the guide section 701b guides its lower end to squeeze open the two swing limit members 753. The two swing limit members 753 swing around the rotating shaft 755 and press the S-shaped elastic return member 752 below them. After the positioning post 751 opens the two symmetrical deformable parts 701c, it enters the locking area 701d between them. After the slider 701 is in place, the two swing limit members 753 are reset under the restoring force of the elastic return member 752 and block the two deformable parts 701c from below. The slider 701 is locked and cannot move backward or upward. The upper guide rail assembly 100 thus obtains a double-safety locking.In use, the upper edge of the glass 1000 is clamped and fixed to each sliding seat 201 by the positioning clamping assembly installed at the positioning hole 202. Each piece of glass 1000 is supported by at least two sliding assemblies 200. When the glass 1000 is pushed and pulled along the length of the guide rail body 101, the guide pulleys 205 in the four mounting slots 206 at the lower end of each sliding seat 201 roll and bear weight in the corresponding guide grooves 102. The guide wheels 203 at the four corners at the upper end roll in the U-shaped guide grooves 103 and are horizontally limited by the arms on both sides of the guide grooves 103. The part of the guide wheel 203 protruding from the side of the sliding seat 201 abuts against the guide groove 103. The sliding process is smooth and without shaking. The opening and closing mechanism is smooth and easy. When disassembly is required, press the two swing limiters 753 to compress the elastic return member 752 and pull the outer sliding member 701 to disengage the positioning post 751 from the locking area 701d. Then lift the upper guide rail assembly 100. The first limiter 302 and the second limiter 306 are deformed under pressure, opening the first limiter groove 608 and the second limiter groove 609. The locking part 603b exits upward from the cavity area, allowing the upper guide rail assembly 100 to be removed as a whole. No tools are required for installation and disassembly. No holes are drilled in the main body of the transportation equipment, and the structural strength of the vehicle body is not damaged. After installation, the overall operation is stable and reliable, which helps to extend the service life of the transportation equipment.
