Description

Technical Field

[0001] The utility model relates to the technical field of frames that can be used for automobile skylight sunshades or insect-proof nets, in particular to a frame assembly. Background Art

[0002] The car sunroof is installed on the roof, which can be used to effectively improve the air circulation in the car, and can also be used to meet the needs of eliminating fog, cooling, and widening the field of vision. However, in summer, after the sunroof is opened, it is easy for flying insects to enter the car, which will cause adverse effects such as dirtying the interior decoration and disturbing the driver's sight, so sometimes an insect net is installed on the car sunroof. Sometimes, in order to prevent sun exposure, a sunshade is installed on the car sunroof. In the prior art, whether it is an insect net or a sunshade, after the frame assembly is assembled (usually assembled by two side rails and beams that are only used for connection), a complete decorative panel is usually pasted on the bottom surface of the frame assembly to achieve the effect of interior decoration. However, the use of the decorative panel not only increases the total thickness of the frame assembly in disguise, reduces the space in the car, but also increases the safety risk caused by the falling off of the decorative panel.

[0047] In order to make the purpose, technical solutions and advantages of the present utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model.

[0048] An insect-proof net, as Figure 1 shown, can be used to be installed at the position corresponding to the car sunroof on the car. After the sunroof is opened, it can prevent flying insects from entering the car through the sunroof.

[0049] The above-mentioned insect-proof net includes components such as two slide rails 1, a first panel 2, a second panel 3, a base 4, a reel 5, a curtain cloth 6, a pull rod 7, etc.

[0050] As shown Figure 1 、 Figure 2 , two slide rails 1 are respectively placed on both sides. The first panel 2 is installed at one end of the two slide rails 1, and a base 4 is installed at the other end of each slide rail 1. A reel 5 is rotatably installed between the two bases 4. The reel 5 is a prior art with an automatic winding function. A pull rod 7 that can move along the length direction of the slide rail is installed between the two slide rails 1. The curtain cloth 6 is a wound insect-proof net cloth in the prior art that can play an insect-proof role. One end of the curtain cloth 6 is wound and connected to the reel 5, and the other end is connected to the pull rod 7.

[0051] When it is necessary to close the curtain cloth 6, drive the pull rod 7 to move on the slide rail 1, and the reel 5 rotates to wind up the curtain cloth 6; when it is necessary to open the curtain cloth 6, drive the pull rod 7 to move on the slide rail 1, and the reel 5 rotates to unfold the curtain cloth 6, which can be used to prevent flying insects from entering the vehicle through the sunroof.

[0052] The assembly relationship between the above-mentioned slide rail 1 and the first panel 2 and the second panel 3 is as shown Figures 1 to 4 :

[0053] The two slide rails 1 have a bottom plate 11. One end of the two slide rails 1 is located on the first panel 2, and the second panel 3 is installed at the other end of the two slide rails 1 and the other end is located on the second panel 3. In this way, the bottom surfaces of the bottom plates 11 of the two slide rails 1, the bottom surface of the first panel 2, and the bottom surface of the second panel 3 together form a decorative surface, that is, the bottom surface of the bottom plate 11 carried by the slide rail 1 itself serves as a part of the overall decorative surface. The decorative surface refers to the surface that is directly exposed after the insect-proof net is installed on the vehicle and can be directly observed by the vehicle occupants. This decorative surface faces the interior of the vehicle to achieve a decorative effect.

[0054] The guide rails of traditional insect-proof nets do not have a bottom plate, while the slide rail 1 of this solution has its own bottom plate 11, and the first panel 2 and the second panel 3 have a wider bottom surface compared with the beams of traditional frames, which can play a role in jointly forming a decorative surface; and with the design that the two ends of the slide rail 1 are located on the first panel 2 and the second panel 3, only the decorative surface can be seen from the interior of the vehicle, and the ends of the slide rail 1 will not be exposed, making it more beautiful.

[0055] Traditional insect-proof nets will paste a decorative board on the bottom of the frame as a whole. For some off-road vehicles equipped with insect-proof nets, this additional pasted decorative board often falls off. However, in this solution, there is no need to additionally add a decorative board after the slide rail 1 is assembled with the first panel 2 and the second panel 3, which not only saves the decorative board but also avoids the phenomenon of the decorative board falling off.

[0056] Better, as shown Figure 2 、 Figure 5 、 Figure 6, on the upper surface of the first panel 2, a baffle 21, a reinforcing rib 22, and a limiting plate 23 are fixed. The baffle 21, the reinforcing rib 22, and the limiting plate 23 are all distributed along the length direction of the first panel 2, and the reinforcing rib 22 is relatively located between the baffle 21 and the limiting plate 23. One end of the bottom of the slide rail 1 is provided with a first notch 101, and the first notch 101 penetrates the inner and outer sides of the slide rail 1. When the first panel 2 is assembled with the slide rail 1, the baffle 21, the reinforcing rib 22, and the limiting plate 23 on the first panel 2 are all placed in the first notch 101.

[0057] Among them, the reinforcing rib 22 is used to improve the strength of the first panel 2; the distance between the baffle 21 and the limiting plate 23 is adapted to the width of the first notch 101. After the baffle 21 and the limiting plate 23 are inserted into the first notch 101, it can play a lateral limiting role and is also convenient for the accurate positioning of the screw holes on the first panel 2 and the slide rail 1 when the first panel 2 and the slide rail 1 are installed with screws; when the curtain cloth 6 is pulled to this end of the slide rail 1, there is often a gap between the curtain cloth 6 and the upper surface of the first panel 2, resulting in light leakage and an unsightly appearance. The baffle 21 provided in this solution can just be used to make up for this light leakage defect; moreover, the baffle 21 is L-shaped, including a vertical portion 211 and a horizontal portion 212. The horizontal portion 212 is formed by extending from the top end of the vertical portion 211 towards the outside of the frame. The setting of the horizontal portion 212 can prevent the top end of the vertical portion 211 from scratching and damaging the curtain cloth 6.

[0058] Moreover, the first panel 2 is integrally formed with the baffle 21, the reinforcing rib 22, and the limiting plate 23, so that the first panel 2 integrates multiple functions and is convenient for production and installation.

[0059] Better, as Figure 6 , a first groove 102 is formed at one end of the bottom surface of the slide rail 1. The first notch 101 is located in the first groove 102. The end of the first panel 2 is installed in the first groove 102. At this time, the baffle 21 and the limiting plate 23 on the first panel 2 are inserted into the first notch 101, and the bottom surface of the first panel 2 is flush with the bottom surface of the slide rail 1. As Figure 2 , Figure 7 , a second groove 103 is formed at the other end of the bottom surface of the slide rail 1. The end of the second panel 3 is installed in the second groove 103, and the bottom surface of the second panel 3 is flush with the bottom surface of the slide rail 1.

[0060] For the formation method of the above first groove 102 and second groove 103 on the slide rail 1, it can be a groove formed by removing the bottom plate at this end of the slide rail, such as Figure 6 , Figure 7 , or it can be a groove formed by the depression and extension of the bottom plate at this end of the slide rail, or formed by other existing technical methods, as long as it is convenient for the installation of the first panel and the second panel and keeps the bottom surfaces of the three flush.

[0061] By setting the bottom surfaces of the sliding rail 1 (i.e., the bottom surface of the bottom plate 11), the first panel 2, and the second panel 3 to be flush with each other, the overall decorative surface can be made flush, which is more aesthetically pleasing. Moreover, the overall height of the frame can be reduced. Compared with the traditional insect-proof net where a decorative board is pasted on the frame, this solution can also reduce the space occupied by the insect-proof net in the vehicle.

[0062] It should be noted that when the bottom surfaces of the three are described as being flush in the text here, in actual manufacturing, due to manufacturing or assembly errors, there will often be a slightly uneven situation, or there are protrusions with different heights added to the bottom surfaces of the three, etc. This also falls within the scope of the three bottom surfaces being flush in this solution.

[0063] The structure of the above-mentioned sliding rail 1 is as Figure 4 :

[0064] In addition to having the bottom plate 11, the sliding rail 1 has a U-shaped wall 12 extending upward from the upper surface of the bottom plate 11. The bottom plate 11 and the U-shaped wall 12 enclose a first closed cavity 121 with a square cross-section as a whole. When the sliding rail 1 is assembled with the connecting die base 93, if the first groove or the second groove is formed by removing the bottom plate at that end, then the inner cavity of the U-shaped wall 12 is used to install the third mounting leg 932 of the connecting die base. If the first groove or the second groove is formed by the bottom plate being concave at that end, then the first closed cavity 121 can be used to install the third mounting leg of the connecting die base. The middle part of the top surface of the U-shaped wall 12 is recessed downward to form a transition wall 13 with a W-shaped cross-section.

[0065] The first end surface at one end of the transition wall 13 (i.e., the left end surface of the left side part 131) and the second end surface at the middle end (i.e., the middle end surface) respectively extend obliquely upward to correspond to the first inclined wall 133 and the second inclined wall 134. The top ends of the first inclined wall 133 and the second inclined wall 134 intersect and then continue to extend to form a transverse wall 135. The first inclined wall 133, the second inclined wall 134, and the left side part 131 of the W-shaped transition wall 13 enclose a second closed cavity 136. And the first inclined wall 133 extends a convex part 137 toward the second closed cavity 136. The convex part 137 and the left side part 131 of the transition wall 13 enclose an arc-shaped first mounting cavity 138 at the lower part of the second closed cavity 136. This first mounting cavity 138 can be used to accommodate the flexible shaft 91 and allow the flexible shaft to move in this cavity. Moreover, the inclined design of the first inclined wall 133 and the second inclined wall 134 can reduce the overall height of the sliding rail 1.

[0066] A third end face at the other end of the transition wall 13 (i.e., the right end face of the right side portion 132) extends upward to form a bent wall 14. The bent wall 14 is relatively located below the transverse wall 135 and a clearance cavity 141 with an opening facing the inside of the slide rail 1 is formed between the bent wall 14 and the transverse wall 135. The clearance cavity 141 communicates with the second installation cavity 139 and is available for the sliding portion 71 provided at the end of the pull rod 7 to move, such as Figure 12 .

[0067] Meanwhile, the second inclined wall 134, the right side portion 132 of the W-shaped transition wall 13, and the bent wall 14 enclose an arc-shaped second installation cavity 139. The second installation cavity 139 can be used to accommodate the flexible shaft 91 and allow the flexible shaft to move within the cavity, such as Figure 12 . The above-mentioned first installation cavity 138 and second installation cavity 139 can radially constrain the side wall of the flexible shaft 91 with a circular cross-section by means of an arc design to prevent the flexible shaft 91 from bending, and at the same time have a moving guiding function.

[0068] Meanwhile, a third installation cavity 15 with an opening facing the inside of the slide rail 1 is enclosed between the bent wall 14 and the top surface on the right side of the U-shaped wall 12 (i.e., the top surface located on the right side of the transition wall). The third installation cavity 15 is available for the folded edge strip on the side of the curtain cloth 6 to move therein, that is, to place the side of the curtain cloth 6 inside the slide rail 1, avoiding the occurrence of a leakage phenomenon due to a lateral gap between the curtain cloth 6 and the slide rail 1.

[0069] The top surface on the right side of the U-shaped wall 12, the bent wall 14, and the transverse wall 135 are arranged vertically at intervals in sequence. On the basis that the height of the transverse wall 135 is reduced by the inclined design of the first inclined wall 133 and the second inclined wall 134, the top surface on the right side of the U-shaped wall 12 is designed to be lower than the top surface on the left side (i.e., the top surface located on the left side of the transition wall), so as to reduce the height of the bent wall 14. On the premise of fully ensuring the use space height of the clearance cavity 141 and the third installation cavity 15, the overall height of the slide rail 1 is further reduced, saving the occupied space in the vehicle.

[0070] Moreover, the inner side edge of the bent wall 14 extends downward to form a hook portion 142. The hook portion 142 bends towards the inside of the third installation cavity 15. The hook portion 142 can be used to form a lateral constraint on the folded edge strip to prevent the side of the curtain cloth 6 from falling off laterally from the slide rail 1, and can also improve the lateral tension of the curtain cloth 6.

[0071] Preferably, the above-mentioned U-shaped wall 12 is located on one side of the bottom plate 11. A bent portion 16 extends upward on the other side of the upper surface of the bottom plate 11. A fourth installation cavity 161 with an opening facing the inside of the slide rail 1 is enclosed between the bent portion 16 and the upper surface of the bottom plate 11. The fourth installation cavity 161 can be used to install an ambient light.

[0072] Moreover, a fifth installation cavity 17 with an upward opening is formed by enclosing between the bending part 16, the U-shaped wall 12, and the bottom plate 11. The fifth installation cavity 17 can be used to assemble the sliding rail 1 and the base 4 by installing the feet of the base 4 at the end, and can be used to install atmosphere lights, etc. in the middle.

[0073] The above-mentioned first installation cavity 138, second installation cavity 139, third installation cavity 15, clearance cavity 141, fourth installation cavity 161, and fifth installation cavity 17 are integrated on a sliding rail 1, enabling the sliding rail 1 to have multiple functions. Moreover, the first installation cavity 138, second installation cavity 139, clearance cavity 141, and third installation cavity 15 cooperate with each other to overall improve the movement coordination effect among the flexible shaft 91, the sliding part 71 at the end of the pull rod 7, and the curtain cloth 6.

[0074] It should be noted that the usage methods of the above-mentioned first installation cavity 138, second installation cavity 139, third installation cavity 15, clearance cavity 141, fourth installation cavity 161, and fifth installation cavity 17 in other embodiments should not be limited by the usage methods in this embodiment, as long as they belong to the reasonable assembly and usage methods that can be achieved by those skilled in the art.

[0075] The structure of the above-mentioned base 4 is as Figures 7 to 9 :

[0076] The outer side wall of the base 4 has a connecting part 41 for installing the connecting part 41 on the top surface of the left side of the U-shaped wall 12 of the sliding rail 1 through screws, thereby realizing the fixed connection between the base 4 and the sliding rail 1. Moreover, an avoidance groove 42 corresponding to the first inclined wall 133 of the sliding rail 1 is formed on the bottom surface of the base 4, thereby reducing the overall height after the base 4 is installed on the sliding rail 1. A rotation hole 43 is formed at one end of the inner side wall of the base 4 for rotatably assembling with the end of the reel 5. Of course, in other embodiments, a rotation groove can also be used instead of the rotation hole to rotatably cooperate with the end of the reel. A connecting column 44 is formed in the middle of the inner side wall of the base 4, and the connecting column 44 is used to connect with the pressing strip 8.

[0077] Moreover, as Figure 8 , a guiding seat 45 is formed at the lower part of the inner side wall of the base 4, and a first installation support foot 451 is formed at the end of the guiding seat 45. By snapping the first installation support foot 451 into the fifth installation cavity 17 of the sliding rail 1, the assembly of the base 4 and the sliding rail 1 is realized. At the same time, an inclined guiding part 452 with a certain slope extends upward at this end of the guiding seat 45. When the base 4 and the sliding rail 1 are assembled, the top surface of the inclined guiding part 452 is flush with the top surface of the right side of the U-shaped wall 12 of the sliding rail 1, which is convenient for guiding the curtain cloth 6 to smoothly enter the third installation cavity 15 of the sliding rail 1 and prevents the curtain cloth 6 from being scratched and damaged by the end face of the sliding rail when entering the sliding rail 1.

[0078] Moreover, at the other end of the inner side wall of the base 4, a hook seat 46 is formed. The hook seat 46 is located above the guide seat 45. A hook 461 is formed on the side of the hook seat 46. The hook 461 is used in cooperation with the inclined guide portion 452. When the base 4 is assembled with the slide rail 1, the position of the hook 461 corresponds to the hook portion 142 of the slide rail 1, as Figure 8 ; when the curtain cloth 6 is guided into the slide rail 1 along the inclined guide portion 452, the hook 461 is used to hook the hem strip on the side of the curtain cloth 6, and the hem strip is smoothly guided into the slide rail 1 and is continuously cooperatively constrained by the hook portion 142.

[0079] Moreover, a second mounting leg 462 is formed at the end of the hook seat 46 for insertion into the clearance cavity 141 of the slide rail 1, thereby realizing the assembly of the hook seat 46 and the slide rail 1.

[0080] The above-mentioned guide seat 45, connecting column 44, and hook seat 46 can all be integrally formed with the base 4. The hook seat 46 can also be detachably assembled with the base 4. For example, a mounting groove 47 is opened at the other end of the inner side wall of the base 4, and the hook seat 46 is installed in the mounting groove 47 by screws. Through the split design, it is convenient to first hang the hem strip of the curtain cloth on the hook 461, and then fix the hook seat 46 in the mounting groove 47 by screws. Compared with the integral design of the hook seat and the base, it can reduce the difficulty of hanging the hem strip and reduce the complexity of mold opening.

[0081] The assembly relationship between the above-mentioned base 4 and the slide rail 1, as Figures 7 to 10 :

[0082] A second notch 104 is opened on the inner side surface of the other end of the slide rail 1 (i.e., the end corresponding to the second panel). The base 4 is placed above the end of the other end of the slide rail 1, so that the connecting portion 41 is located on the top surface on the left side of the U-shaped wall 12 of the slide rail 1 and is fixed together by screws. The first inclined wall 133 of the slide rail 1 is placed in the avoidance groove 42 of the base 4, the guide seat 45 is placed in the second notch 104, the first mounting leg 451 of the guide seat 45 is inserted into the fifth mounting cavity 17, and the second mounting leg 462 of the hook seat 46 is inserted into the clearance cavity 141. The connecting portion 41 is fixed on the top surface on the left side of the U-shaped wall 12 by screws, thereby realizing the assembly of the base 4 and the slide rail 1.

[0083] The assembled base 4 is relatively located above the second panel 3, and the second panel 3, the end of the slide rail 1, and the base 4 are arranged vertically and stacked.

[0084] Preferably, a vertical hem 31 is formed upward on the inner side edge of the second panel 3 (as Figure 2), the vertical folding edge 31 can be used to reduce the distance between the upper surface of the second panel 3 and the curtain cloth 6, make up for the light leakage defect, and at the same time, when installing the second panel 3 in the second groove 103 of the slide rail 1, the vertical folding edge 31 can be used to abut against the end face of the slide rail 1 corresponding to the second notch 104, which is convenient for the installation and positioning of the second panel 3.

[0085] The frame assembly mechanism, such as Figure 1 , Figure 2 :

[0086] The above two slide rails 1, the first panel 2 and the second panel 3 together form a frame, and the curtain cloth 6 can move back and forth within the frame. The first panel 2 and the second panel 3 can also improve the stability of the frame. By installing a base 4 at the other end of the slide rail 1, it can be used to assemble the reel 5, thus forming a frame assembly that can be used to assemble the reel 5 and the curtain cloth 6.

[0087] The assembly relationship among the frame assembly, the reel 5, the curtain cloth 6 and the pull rod 7 is as shown in Figure 1 , Figure 2 :

[0088] The two ends of the above-mentioned reel 5 are respectively rotatably installed in the rotation holes 43 of the base 4, so as to realize the rotatable installation of the reel 5 between the two bases 4.

[0089] A pressure strip 8 is inserted and installed between the connecting columns 44 of the two bases 4. The pressure strip 8 is used to prevent the curtain cloth 6 from warping and at the same time change the height of the curtain cloth 6 unfolded from the reel 5 so as to be smoothly introduced into the third installation cavity 15 of the slide rail 1.

[0090] The two ends of the above-mentioned pull rod 7 are respectively formed with a sliding part 71. The sliding part 71 can be a slider (such as Figure 12 ) additionally installed at both ends of the pull rod 7, and in other embodiments, it can also be integrally formed with the pull rod 7. The sliding parts 71 at both ends are respectively slidably installed in the clearance cavities 141 of the two side slide rails 1. Preferably, the sliding part 71 can additionally have a limiting column part 72 corresponding to the arc of the second installation cavity 139. The limiting column part 72 is used to connect a soft shaft 91 described below, and at the same time, the limiting column part 72 is slidably installed in the second installation cavity 139 and is restricted to prevent the sliding part 71 from falling off the slide rail 1 horizontally.

[0091] The unfolding and retracting actions of the above-mentioned insect-proof net cloth can be manual operation or electric operation.

[0092] Taking the electric operation as an example below, an implementation scheme of the electric operation is given, such as Figure 1 , Figure 2 , Figure 10 , Figure 11 :

[0093] On one side of the base corresponding to the above-mentioned frame assembly, an electric drive assembly is installed for driving the sliding part 71 of the pull rod 7 to reciprocate in the slide rail 1. The electric drive assembly is on the same side as the reel 5 and both are located above the second panel 3. Of course, in other embodiments, the electric drive assembly can also be arranged on the opposite side of the reel, and at the same time, the assembly relationship between the electric drive assembly and the slide rail, panel, etc. can be changed appropriately.

[0094] Moreover, the base 4 is also relatively located above the second panel 3. The vertical folding edge 31 of the second panel 3 abuts against the end face of the slide rail 1 corresponding to the second notch 104, so that after the insect-proof net is installed in the vehicle, the electric drive assembly, the reel 5, and the base 4 cannot be seen from inside the vehicle, achieving a good decorative effect.

[0095] The electric drive assembly includes a drive motor integrated module 92 and two connecting mold bases 93. The two connecting mold bases 93 are respectively installed on both sides of the slide rail 1. Specifically, a third installation support foot 932 is formed on the connecting mold base, and the third installation support foot 932 is inserted into the inner cavity of the U-shaped wall 12. In this embodiment, screws are further used to fix the base 4, the slide rail 1, and the third installation support foot 932 together, and all are placed on the second panel 3, as Figure 10 shown.

[0096] The two connecting mold bases 93 are respectively connected to the drive motor integrated module 92 through a connecting beam 94. The three can be disassembled and assembled through the connecting beam 94, realizing modularization for easy adjustment of the spacing, and replacing the traditional one-piece of the three, saving the mold opening cost and improving the applicability to different vehicle models.

[0097] Among them, the drive motor integrated module 92 includes a motor, a reducer, a drive wheel that can be meshed and driven with the flexible shaft 91, and two flexible shafts 91 passing through the integrated module. The drive wheel is driven by the motor to mesh and drive to drive the flexible shaft 91 to move. The technology of the drive motor integrated module 92 driving the two flexible shafts 91 to drive the sliding part 71 in the two side slide rails to reciprocate belongs to the existing technical knowledge and will not be elaborated here.

[0098] Two through grooves 931 for the flexible shaft 91 to pass through are opened on the connecting mold base 93. One through groove 931 is communicated with the second installation cavity 139 of the slide rail 1, and the other through groove 931 is communicated with the first installation cavity 138 of the slide rail 1. A conduit 95 for the flexible shaft 91 to pass through is connected between the connecting mold base 93 and the drive motor integrated module 92, and the conduit 95 is communicated with the through groove 931.

[0099] When the insect-proof net cloth needs to be deployed, the driving motor integrated module 92 drives the forward ends of the two flexible shafts 91 (the end where the flexible shaft is connected to the limit post part is called the forward end) to push the sliding part 71 forward in the second installation cavity 139 of the two side slide rails 1. The conduit 95 and the second installation cavity 139 can radially constrain the flexible shafts 91 to prevent bending and ensure the driving effect of driving the sliding part 71 forward, thereby driving the curtain cloth 6 to be deployed by the pull rod 7; when the insect-proof net cloth needs to be retracted, the driving motor integrated module 92 drives the forward ends of the two flexible shafts 91 to retreat in the second installation cavity 139, and the reel 5 automatically retracts. At this time, the rear ends of the two flexible shafts 91 (the relative end of the forward end of the flexible shaft is called the rear end) move forward in the first installation cavity 138 of the other slide rail 1, that is, the first installation cavity 138 provides a space for accommodating and moving the rear ends of the flexible shafts 91.
