Description

Technical Field

[0001] The utility model relates to the technical field of pneumatic comfort equipment, in particular to a combined positioning component, a positioning structure and an intelligent device. Background Art

[0002] During the installation process of automotive parts, positioning is often required before screw or clip installation. In actual products, factors such as sheet metal and plastic manufacturing processes often result in poor positioning or large dimensional deviations, leading to actual positioning failure, affecting installation efficiency or causing other abnormal noises, permanent damage to plastic parts, etc.

[0003] For example, in a car seat with a pneumatic comfort system, the air pump of the pneumatic comfort system is carried on a base shell, which is fixedly mounted on the back panel of the seat to achieve fixed installation of the air pump on the seat. In the prior art, a positioning column is usually provided on the seat back panel, a positioning hole is provided on the base shell, and a reinforcing rib is integrally formed on the positioning column to fit with the positioning hole. The positioning column and the positioning hole are positioned and engaged with each other to achieve alignment of the screw hole on the base shell with the screw hole on the seat back panel. However, if the positioning hole and the screw hole molding of the base shell are defective or have dimensional deviations, the screw hole on the base shell and the screw hole on the seat back panel cannot be aligned, making it difficult to install the base shell on the seat back panel. Alternatively, a large gap will exist between the screw hole of the base shell and the screw hole of the seat back panel, which will reduce the assembly strength between the base shell and the seat back panel, and the base shell will produce obvious vibration and abnormal noise when the air pump is working.

[0004] In addition, by providing reinforcing ribs on the positioning column to achieve snap-on positioning, the reinforcing ribs on the positioning column are easily worn after multiple disassembly and assembly, so that the positioning column only has a positioning and guiding function, and there is a gap between the base shell after positioning, further reducing the installation strength of the base shell and the seat back panel. When the air pump is working, it will further cause the base shell to produce obvious vibration and abnormal noise.

[0005] Therefore, in order to solve the above technical problems, it is urgent to develop a positioning component. Utility Model Content

[0044] To make the purpose, technical solutions and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. The described embodiments are only part of the embodiments of the present invention, not all of the embodiments.

[0045] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but rather merely represents selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by a person of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0046] Please see the attached Figure 1 ~Attached Figure 3 In the first aspect, the combined positioning assembly 1 provided by the embodiment of the present invention includes a fixing member 10 and an adapter 20 .

[0047] Among them, see Figure 1 , Figure 1 The diagram illustrates the structural relationship between the fixing member 10 and the adapter 20 in an embodiment of the present invention. Specifically, the fixing member 10 includes a cap portion 11 and a stem portion 12 connected to each other, with a first engaging portion 121 provided on the stem portion 12. The adapter 20 has an engaging hole 21 through which the stem portion 12 of the fixing member 10 passes, and a second engaging portion 211 is provided in the engaging hole 21 to engage with the first engaging portion. The adapter 20 has a claw 22 at its end.

[0048] During the combined positioning and use of the fixing member 10 and the adapter 20, when the rod 12 of the fixing member 10 is passed through the clamping hole 21 of the adapter 20, the first clamping portion 121 set on the rod 12 is passed through the clamping hole 21, and when the first clamping portion 121 passes over the second clamping portion 211, along the direction opposite to the passing direction, the side of the first clamping portion 121 close to the cap 11 of the fixing member 10 abuts against the side of the second clamping portion 211 facing away from the cap 11 of the fixing member 10, so that the first clamping portion 121 is clamped to the second clamping portion 211, and the second clamping portion 211 is located between the first clamping portion 121 and the cap 11, so that the fixing member 10 and the adapter 20 are clamped and fixed. Preferably, the fixing member 10 can be a soft member such as a silicone rubber nail, so that the first clamping portion 121 of the fixing member 10 can pass through the clamping hole of the adapter 20, thereby improving the assembly reliability of the combined positioning component 1. In addition, the adapter 20 can be a plastic member.

[0049] In some preferred embodiments, see Figure 2 , Figure 2 The diagram illustrates the structural relationship between the first clamping portion 121 and the first guide surface 1211 in the embodiment of the present invention. Specifically, the first clamping portion 121 has a first guide surface 1211 for guiding the first clamping portion 121 to be clamped to the second clamping portion 211 when passing through the clamping hole 21. Among them, the first guide surface 1211 can be an inclined surface. Specifically, along the direction in which the rod portion 12 passes through the clamping hole 21, the inclined surface is arranged on the surface of the first clamping portion 121 facing the clamping hole 21. The inclined surface starts from the periphery of the first clamping portion 121 and the outer diameter gradually decreases along the direction of penetration. When the rod portion 21 passes through the clamping hole 21, the first guide surface 1211 set by the inclined surface directly contacts the second clamping portion 211 and enables the first clamping portion 121 to gradually slide over the second clamping portion 211, and then clamp on the second clamping portion 211 after passing over the second clamping portion 211, so that the first clamping portion 121 is more labor-saving in the process of passing through the clamping hole 21.

[0050] In some preferred embodiments, the second engaging portion 211 has a second guide surface 2111 for guiding the first engaging portion 121 to engage with the second engaging portion 211 when passing through the engaging hole 21. The second guide surface 2111 may be an inclined surface. Specifically, along the direction in which the engaging hole 21 receives the rod 12 for entry, the inclined surface is provided on the surface of the second engaging portion 211 facing the rod 12. The inclined surface starts from the periphery of the second engaging portion 211 and its outer diameter gradually decreases in a direction opposite to the entry direction. When the rod 21 enters the engaging hole 21, the second guide surface 2111 provided with the inclined surface directly contacts the first engaging portion 211, allowing the first engaging portion 121 to gradually slide through the second engaging portion 211. This allows the first engaging portion 121 to pass through the engaging hole 21 more smoothly, and then engage with the second engaging portion 211 after passing through the second engaging portion 211, thereby improving assembly efficiency.

[0051] It can be understood that the first guide surface 1211 and the second guide surface 2111 cooperate with each other to make the process of the rod portion 12 of the fixing member 10 passing through the engaging hole 21 more labor-saving and smooth, thereby improving assembly efficiency.

[0052] In other embodiments, the surface of the first engaging portion 121 opposite the first guide surface 1211 can be set as a flat surface, and / or the surface of the second engaging portion 211 opposite the second guide surface 2111 can be set as a flat surface. When the first engaging portion 121 passes through the engaging hole 21 and engages with the second engaging portion 211, the flat surface on the first engaging portion 121 faces the flat surface on the second engaging portion 211. The flat contact engagement improves the engagement stability between the first engaging portion 121 and the second engaging portion 211, thereby preventing the first engaging portion 121 from being disengaged from the second engaging portion 211 and falling out of the engaging hole 21.

[0053] In some preferred embodiments, please refer to Figure 1 , Figure 1 The diagram illustrates the structural relationship between the first orienting portion 122 and the second orienting portion 212 in an embodiment of the present invention. Specifically, the first orienting portion 122 is provided on the rod portion 12 of the fixing member 10, and the second orienting portion 212 is provided on the engaging hole 21 of the adapter 20, which cooperates with the first orienting portion 122 to guide the rod portion 12 through the engaging hole 21, thereby improving assembly convenience.

[0054] In some preferred embodiments, the first orientation portion 122 extends to the first clamping portion 121. When the rod portion 12 of the fixing member 10 is inserted into the clamping hole 21, the second orientation portion 212 cooperates with the first orientation portion 122 to guide the first clamping portion 121 to pass through the clamping hole 21 and be clamped to the second clamping portion 211, thereby preventing the first orientation portion 122 from interfering with the depth of the first clamping portion 121 entering the clamping hole 21. For example, the first clamping portion 121 can be oriented to smoothly pass over the first orientation portion 122 and penetrate into the clamping hole 21 to complete the clamping connection with the second clamping portion 211, thereby ensuring the clamping stability of the first clamping portion 121 and the second clamping portion 211, thereby improving the assembly reliability of the combined positioning component 1.

[0055] In some preferred embodiments, please combine Figure 3 and Figure 4 , Figure 3 and Figure 4 The diagram illustrates the structural relationship between the guide slot 1221 and the guide post 2121 in an embodiment of the present invention. Specifically, the first orientation portion 122 includes the guide slot 1221, and the second orientation portion 212 includes the guide post 2121 adapted to fit within the guide slot 1221. When the rod 12 of the fixture 10 passes through the engaging hole 21, the guide post 2121 aligns with the guide slot 1221 and slides relative to it in a directional manner, allowing the rod 12 to be inserted into the engaging hole 21. This ensures that the first engaging portion 121 and the second engaging portion 211 are aligned and engaged, improving ease of assembly. In addition, when the rod portion 12 is inserted into the snap-fitting hole 21, in the rotational circumferential direction, the guide column 2121 is limitedly snap-fitted to the guide groove 1221, so that the fixing member 10 is snap-fitted to the adapter 20, thereby realizing the alignment snap-fitting between the adapter 20 and the fixing member 10, and at the same time improving the anti-torsion performance between the fixing member 10 and the adapter 20, preventing twisting between the fixing member 10 and the adapter 20, thereby improving the connection stability between the fixing member 10 and the adapter 20.

[0056] Preferably, there are a plurality of guide posts 2121 and a plurality of second clamping portions 211. Accordingly, a plurality of guide grooves 1221 are provided to correspond to the plurality of guide posts 212. The first clamping portion 121 is thus divided into a plurality of sections by the plurality of guide grooves 1221 extending to the first clamping portion 121. The plurality of guide posts 2121 and the second clamping portions 211 are alternately spaced and distributed along the inner circumferential wall of the clamping hole 21. When the rod 12 of the fixing member 10 passes through the clamping hole 21, the plurality of guide posts 2121 cooperate with the plurality of guide grooves 1221 provided on the rod 12 and extending to the first clamping portion 121 to guide the first clamping portion 121 to clamp to the second clamping portion 211, and the clamping is limited in the rotational circumferential direction, thereby improving the connection stability of the overall structure.

[0057] In other preferred embodiments, the rod portion 12 of the fixing member 10 is provided with a thread, specifically an external thread provided on the portion of the rod portion 12 not provided with the first clamping portion 121. Thus, the rod portion 12 of the fixing member 10 can be threadedly positioned and engaged with the internally threaded positioning hole, thereby improving the positioning stability of the fixing member 10 in the positioning hole and thereby ensuring the positioning reliability of the combined positioning assembly 1.

[0058] Specifically, the claw 22 on the adapter 20 extends axially from the end of the adapter 20 that is inserted into the facing rod portion 12 and is folded outward. In some embodiments, it is understood that the adapter 20 body has a through-molded engaging hole 21, and the claw 22 is integrally formed and extended from the end of the adapter 20 body to facilitate the engagement and positioning of the adapter 20 in the positioning hole.

[0059] In a second aspect, based on the above embodiments, an embodiment of the present utility model provides a positioning structure 2.

[0060] The positioning structure 2 of the embodiment of the utility model is shown in the attached Figure 4 ~Attached Figure 5 , including a base shell 30, a mounting plate 40 and the above-mentioned combined positioning component 1.

[0061] Among them, see Figure 5 , Figure 5 The diagram illustrates the structural relationship between the mounting plate 40, the base shell 30, and the combined positioning assembly 1 in an embodiment of the present invention. Specifically, a first positioning hole 41 is provided on the mounting plate 40, and a second positioning hole 31 corresponding to the first positioning hole 41 is provided on the base shell 30. The adapter 20 is provided between the mounting plate 40 and the base shell 30, and the first positioning hole 41, the engaging hole 21 of the adapter 20, and the second positioning hole 31 are concentrically arranged. The rod 12 of the fixing member 10 is sequentially passed through the second positioning hole 31 and the engaging hole 21 and inserted into the first positioning hole 41. The second engaging portion 211 is engaged between the cap portion 11 and the first engaging portion 121. The claw 22 passes through the second positioning hole 31 toward the base shell 30 and engages with the base shell 30, so that the adapter 20 is engaged with the base shell 30, thereby fixing the overall combined positioning assembly 1 relative to the base shell 30 to improve the positioning integrity and stability.

[0062] In the positioning structure 2 of the embodiment of the present utility model, the adapter 20 is arranged between the first positioning hole 41 and the second positioning hole 31. The adapter 20 has one end of the claw 22 facing the base shell 30 and passing through the second positioning hole 31, so that the claw 22 is clamped on the base shell 30, and the rod portion 12 of the fixing member 10 is passed through the second positioning hole 31 and the clamping hole 21 in sequence and fixed in the first positioning hole 41. At this time, the first clamping portion 121 is clamped on the second clamping portion 211, and the second clamping portion 211 is located between the first clamping portion 121 and the cap portion 11 of the fixing member 10, so that the base shell 30 and the mounting plate 40 are positioned and fixed, and then the first screw hole 60 of the base shell 30 and the second screw hole 70 of the mounting plate 40 are aligned, so that the base shell 30 and the mounting plate 40 can be accurately fixed by screws 80 or buckles in the future, so that the base shell 30 can be accurately fixed on the mounting plate 40. Figure 4 As shown, a stud 50 is provided on the mounting plate 40, a second screw hole 70 is opened on the stud 50, and a first screw hole 60 is opened on the base shell 30. After positioning the base shell 30 and the mounting plate 40 by using the combined positioning component 1, the first screw hole 60 of the base shell 30 and the second screw hole 70 of the stud 60 of the mounting plate 40 can be accurately aligned to ensure the assembly strength of the base shell 30 and the mounting plate 40, and avoid positioning failure due to the gap between the first screw hole 60 and the second screw hole 70, which in turn leads to low assembly strength and further causes obvious vibration or abnormal noise.

[0063] The positioning structure 2 of the embodiment of the present invention adopts the combined positioning component 1 provided in the embodiment of the present invention to perform fixed installation and positioning of the base shell 30 and the mounting plate 40, so that the base shell 30 and the mounting plate 40 can be accurately fixed and positioned, thereby achieving the alignment of the first screw hole 60 of the base shell 30 and the second screw hole 70 of the mounting plate 40, and then the base shell 30 and the mounting plate 40 are positioned before the snap fasteners or screws 80 are installed, avoiding positioning failure resulting in insufficient assembly strength, and thus causing abnormal noise or vibration problems. Specifically, when using the combined positioning assembly 1 to fix and position the base shell 30 and the mounting plate 40, the end of the adapter 20 facing away from the clamping claw 22 is positioned to align with the second positioning hole 31 of the base shell 30, and is clamped to the base shell 30 through the clamping claw 22. The rod 12 of the fixing member 10 is sequentially passed through the second positioning hole 31 and the clamping hole 21 and is inserted into the first positioning hole 41, thereby realizing precise fixed positioning of the base shell 30 and the mounting plate 40, and then realizing the alignment of the first screw hole 60 of the base shell 30 and the second screw hole 70 on the mounting plate 40, avoiding the problem of reduced assembly emphasis caused by a large gap between the first screw hole 60 and the second screw hole 70, thereby causing obvious vibration or abnormal noise.

[0064] In some embodiments, the rod portion 12 of the fixing member 10 can be designed to have an outer diameter larger than the inner diameter of the first positioning hole 41 of the positioning column 42, so that the rod portion 12 and the first positioning hole 41 can be fixed together by an interference fit to enhance the positioning stability of the base shell 30 and the mounting plate 40.

[0065] In other embodiments, the first positioning hole 41 on the positioning column 42 can be provided with an internal thread, and the rod portion 12 of the fixing member 10 with an external thread and the first positioning hole 41 of the positioning column 42 can be fixed together by screwing to enhance the stability of the positioning of the base shell 30 and the mounting plate 40.

[0066] The fixing part 10 can be a silicone rubber nail, which makes it easier for the first clamping portion 121 of the fixing part 10 to pass through the clamping hole 21 of the adapter 20 and interference fit in the first positioning hole 41, and the connection is more stable; the cap portion 11 of the fixing part 10 can play an auxiliary guiding role during installation, and a flexible fit and abutment is achieved between the fixing part 10 and the adapter 20 and the positioning column 42, which can reduce abnormal sounds and noises caused by the resonance of the positioning structure 2.

[0067] In addition, by adjusting the engagement depth between the fixing member 10 and the first positioning hole 41 and / or adjusting the thickness of the adapter 20, it is possible to accommodate the positioning and fixation of more positioning mechanisms 2 of different specifications, while being flexible in assembly and disassembly for easy maintenance. The hardness of the silicone rubber nails can also be adjusted according to actual assembly requirements to ensure assembly convenience and stability.

[0068] In some preferred embodiments, see Figure 6 , Figure 6 The diagram illustrates the structural relationship between the positioning post 42, adapter 20, and fixture 10 in an embodiment of the present invention. Specifically, to reduce the clearance between the base housing 30 and the mounting plate 40, the mounting plate 40 is provided with a positioning post 42, which extends from a protrusion on the mounting plate 40. A first positioning hole 41 is defined within the positioning post 42. When the fixture 10 and adapter 20 are used to position the base housing 30 and the mounting plate 40, the rod 12 of the fixture 10 penetrates and positions the second positioning hole 31 in the base housing 30, the engaging hole 21 in the adapter 20, and the first positioning hole 41 in the positioning post 42.

[0069] In a further preferred embodiment, a positioning groove that is adapted to the positioning column 42 can be provided at the end of the adapter 20 facing away from the clamping claw 22, so that the adapter 20 is adapted to be connected to the positioning column 42, and the rod portion 12 of the fixing member 10 is passed through the second positioning hole 31 and the clamping hole 21 and fixed in the first positioning hole 41, so that the connection between the adapter 20, the fixing member 10 and the mounting plate 40 is more stable, thereby improving the overall structural reliability.

[0070] In a third aspect, based on the above embodiments, the present invention provides an intelligent device.

[0071] The intelligent device of the present embodiment includes a pneumatic comfort system, a base housing 30, and a mounting plate 40. The pneumatic comfort system includes an air source device, an air distribution device, and an air bag. The air bag is ventilated and connected to the air source device through the air distribution device. The base housing 30 is used to support the air source device. For example, when the air source device is an air pump, the base housing 30 can be a housing compatible with the air pump and capable of mounting and supporting the air pump. The base housing 30 is positioned and fixed to the mounting plate 40 using the positioning structure 2 described above.

[0072] The smart device can be a seat, such as an office chair, massage chair, or car seat. The pneumatic comfort system includes one or more of a pneumatic massage system, a pneumatic lumbar support system, and a pneumatic wing support system. The air source device includes, but is not limited to, an air pump, an air compressor, or an integrated pump-valve structure. The air distribution device includes, but is not limited to, an air valve, a fluid oscillator, and the like, such as a solenoid valve. The corresponding airbags can be massage bags, lumbar support bags, or wing support bags. In the pneumatic comfort system, the air source device supplies air to the airbags, inflating them to adjust the comfort of the smart device, while the air distribution device controls the inflation and deflation of the airbags.

[0073] In an embodiment of the present utility model, the base shell 30 is positioned and fixed on the mounting plate 40 using a positioning structure 2. Due to the flexible connection between the adapter 20, the fixing member 10 and the mounting plate 40, and the first screw hole 60 of the base shell 30 and the second screw hole 70 of the mounting plate 40 are precisely aligned under the action of the positioning structure 2, the positioning failure between the base shell 30 and the mounting plate 40 is avoided, which causes the assembly strength to be reduced, and further causes the air source device of the pneumatic comfort system to resonate when working, causing the base shell 30 to produce obvious vibration and abnormal noise, thereby improving the user experience.
