Description

Technical Field

[0001] The invention relates to the technical field of metal profile application, and in particular to a modular assembly component based on square tube profile and an assembled finished product. Background Art

[0002] Desktop small indoor toy cars are very popular toys for many children, which are mainly controlled by pre-programmed remote controls and controlled motors and steering gears. However, conventional toy cars are mostly solid finished products, lacking the variability of subsequent configuration and operation, so it is easy to make people lose interest, and it is difficult to achieve the purpose of promoting learning ability and stimulating interest in learning.

[0003] Another existing ride-on toy car has a height that is basically not adjustable or is rather troublesome to adjust, which is not conducive to children's entertainment and play. In addition, the chassis of the toy car is integrated and can only be completely replaced if damaged. Therefore, the replacement cost is relatively high, which increases the household expenditure of ordinary families to a certain extent.

[0004] There is also a type of assembled building block toy car, among which the small particle building block car of Lego is the most popular. By using a variety of building blocks made of plastic particles to assemble the frame, and integrating electric modules such as motors, control modules, and drive modules, a finished toy that can simulate various driving modes can be obtained. After assembling various painted shell parts, you can also get models that simulate various brands and models and have a cool visual effect, which has become a hot item for friends to play with. However, this type of assembled car is small in size (usually more than ten times the original car is reduced in proportion), has low structural strength (even falls apart if it cannot withstand a collision), and cannot meet the load-bearing requirements of driving, and only exists as a desktop toy. Moreover, in addition to the changeable shell, its frame structure is usually restricted by the instructions of the product design and is limited to a single structure, which makes it impossible to open up thinking for innovative assembly.

[0005] As an important tool for intellectual development and entertainment, and with the continuous improvement of people's living standards, the pursuit of quality and function of toy cars is getting higher and higher.

[0044] The specific implementation modes of the present invention will be further described below in conjunction with the accompanying drawings of the embodiments, so that the technical solution of the present invention is easier to understand and grasp, thereby making a clearer definition of the protection scope of the present invention.

[0045] The designers of the present invention have focused on the fact that desktop building blocks and toy vehicles lack the vitality to grow with the age of players, and have focused on metal profiles (especially square tube aluminum profiles) that are widely used in the current market. They have innovatively proposed a modular assembly component and assembled product, which is conducive to expanding teaching ideas, improving teaching quality, and also conducive to the flexible application and disassembly and storage of various tools used in life and work affairs.

[0046] The present invention is based on a modular assembly of square tube profiles. From a technical overview, it consists of one or more square tube profiles that are fixed by fastening bolts and sliders with screw holes through modular bases of one or more shapes. The following square tube profiles are preferably aluminum profiles, and their cross-sections perpendicular to the length direction are as follows: Figure 1 As shown, the aluminum profile 1 is provided with a through hole 11 passing through along the central axis, and the end of the through hole of each cutting section is processed with an internal thread adapted to the fastening bolt. The four sides of the aluminum profile are provided with a T-slot 12 which extends linearly and is adapted to accommodate the slider. Usually, the aluminum profile has specifications such as 20mm×20mm, 30mm×30mm and 40mm×40mm, which can be freely selected according to actual needs; the size of the mounting surface of the modular seat body used for assembly matches the specifications of the corresponding aluminum profile to be mounted. The modular seat body includes a docking base for linearly connecting aluminum profiles, a transfer base for right-angled connecting aluminum profiles, a bearing seat for single or side-by-side assembly of aluminum profiles, a toothed base for increasing the single-end axial rotation adjustable capacity of the aluminum profile, a U-shaped seat for increasing the single-end mounting peripheral swinging capacity of the aluminum profile, and a straight tooth seat for increasing the angular adjustable capacity between aluminum profiles and its matching double-sided toothed ring. On the basis of the above aluminum profiles and modular base bodies being available in sufficient quantity and matching in specifications, the aluminum profiles can be cut in sections according to the teaching plan and the tools or machines designed for daily life, and the modular base body can be used to assemble and combine with the aluminum profiles, so that the aluminum profiles have the ability of linear connection, right-angle connection, end or interrupted bearing attachment, single-end axial rotation adjustment, single-end peripheral swing attachment, and angle-adjustable assembly between segmented aluminum profiles. The products obtained by assembling aluminum profiles will no longer be limited to regular-shaped and relatively static finished products, but can also be expanded to various heterogeneous shapes and practical finished products suitable for both static and dynamic applications by using modular base bodies to adapt to common bearings, rods, reducers, shock absorbers, motors, transmission components, various formed wooden boards, etc.

[0047] The structural design logic of the modular assembly components of the present invention can be understood from the further detailed features of the mutual assembly of the modular base and the aluminum profile. Figures 2 to 4 The figure is a schematic diagram of the three-dimensional structure of the three docking bases in the modular seat body of the present invention. Specifically, Figure 2The first docking base 21 shown is formed with a first base 211 corresponding to the outer contour of the aluminum profile, and the main body is a square sheet (the thickness can be customized). When clamped between two sections of aluminum profile, its outer wall is flush with the aluminum profile or has no abrupt feeling. The first base 211 is provided with a center hole 9 corresponding to the stud-type fastening bolt, and the two side surfaces of the first base 211 are integrally formed with an annular rack 212. Of course, it can also be integrally formed into a buckle that is compatible with the T-slots of the aluminum profile. During actual assembly, the fastening bolt first penetrates the center hole from one side and is fixed in the through hole of the first section of the aluminum profile, so that the edges of the first section of the aluminum profile and the first base are aligned and radially locked, and then the through hole of the second section of the aluminum profile to be connected is aligned with the exposed part of the fastening bolt, and the screw is tightened until all edges are aligned and radially locked.

[0048] Figure 3 The second docking base 22 shown is formed with a second base 221 corresponding to the outer contour of the aluminum profile and in the form of an L-shaped block. The second base 221 is provided with a center hole 9 corresponding to the stud-type fastening bolt, and the bottom of the second base is integrally formed with an annular rack 222 (it can also be a buckle that is compatible and limited to be located in the aluminum profile. Since most of the figures are annular racks, it is set as a preferred setting, and other modular bases are similar). The half side of the second base is provided with a gear table 223 and an assembly hole 224 that is axially perpendicular to the center hole for combining the two into one. Therefore, when the aluminum profile is linearly connected, the annular rack of a second docking base is first placed directly opposite to the end face of a section of the aluminum profile, and the fastening bolts are inserted and tightened in the center hole to align the edges to complete one set of assembly. The other set of assembly is completed in the same way, and then the two second docking bases are assembled inverted, the gear tables are filled with each other, and the assembly holes are coaxial. Bolts are inserted through the assembly holes and nuts are tightened to complete the linear connection of the two sections of aluminum profiles.

[0049] Figure 4 The third docking base 23 shown is formed with a third base 231 corresponding to the outer contour of the aluminum profile and in a block shape. The third base 231 is provided with a central hole 9 for the corresponding fastening bolt to penetrate, and the bottom surface of the third base is integrally formed with a groove 232a and a pair of buckles 233a, and the top surface of the third base is integrally formed with a groove 232b and a pair of buckles 233b, wherein the grooves on both sides are orthogonal to each other, and each groove is provided with an assembly hole corresponding to the back buckle. When the aluminum profile is linearly connected, firstly, a pair of buckles on one side (top or bottom) of a third docking base are accommodated and limited in the aluminum profile, and then fastening bolts are passed through the central hole to assemble and fix with the aluminum profile; the other group of assembly is completed in the same way, and then two third docking bases are spliced ​​relative to each other, so that the pair of buckles facing outward are compatible with the groove facing outward, and then small bolts are used in each T-slot of the aluminum profile to penetrate the assembly hole and tighten with nuts to complete the linear connection of the two sections of aluminum profile.

[0050] like Figure 5As shown, it is a three-dimensional structural schematic diagram of a transfer base in the modular assembly component of the present invention. It can be seen that the transfer base 3 is formed with a fourth base 31 bent at a right angle, each side of the fourth base 31 corresponds to the outer contour of the aluminum profile and is provided with a central hole 9 corresponding to the fastening bolt, and an annular rack 32 is integrally formed outward, and the transfer base is integrally formed with a triangular wing plate 33 with a strong right-angle bend on both sides of the fourth base. When the aluminum profile is connected at a right angle, a section of the aluminum profile is facing the annular rack provided on one side of the fourth base and is connected with the fastening bolts to lock it, and then another section of the aluminum profile is facing the annular rack provided on the other side of the fourth base and is connected with the fastening bolts to lock it. There is no sharp edge pointing outward between the two sections of aluminum profile connected at a right angle, which can prevent collision damage. Here, the annular rack mainly plays the role of increasing damping, so that the aluminum profile after assembly will not rotate axially. Of course, this puts higher requirements on the strength and durability of the annular rack.

[0051] like Figure 6 and Figure 7 The figure shows the three-dimensional structure of two bearing seats in the modular seat body of the present invention. Specifically, Figure 6 The straight-cylindrical bearing seat 41 corresponding to the single-end mounting of the aluminum profile is shown. The main body of the straight-cylindrical bearing seat is a block structure with a square bottom and a semi-cylindrical top, and is provided with a center hole 9 that penetrates the top and bottom and is corresponding to the fastening bolt. The bottom surface of the straight-cylindrical bearing seat is integrally formed with an annular rack 411, and a pair of side surfaces of the straight-cylindrical bearing seat are formed with a sink groove 412 for embedding the bearing, and the centers of the two sink grooves are through-set. After completing the same assembly process as above, the straight-cylindrical bearing seat is integrally joined to the end of the aluminum profile, and the bearing is embedded in the sink groove, so that the aluminum profile has the ability to pass through the rotating shaft at a single end, meeting the specific finished product assembly design requirements.

[0052] Figure 7The hexagonal bearing seat 42 is shown to be assembled side by side and mounted sideways with corresponding aluminum profiles. The main body of the hexagonal bearing seat is a dome-shaped triangular block structure, and is provided with two center holes 9 that penetrate to the bottom surface and corresponding to the fastening bolts, and the wheelbase of the two center holes is slightly larger than the width of the aluminum profile. The bottom surface of the hexagonal bearing seat is integrally formed with two annular racks 421 (coaxial with each center hole) or two sets of cross-shaped buckles. A pair of side surfaces of the hexagonal bearing seat 42 are formed with sink grooves 422 for embedding bearings, and the center penetration direction S of the two sink grooves is perpendicular to the connecting plane Z of the two center holes. The hexagonal bearing seat has a variety of flexible assembly methods relative to the aluminum profile: one is to arrange two sections of aluminum profile side by side (spacing ≥ 0), and use the same assembly process as mentioned above to install the hexagonal bearing seat on the flush ends of the two sections of aluminum profile, so that the aluminum profile with doubled strength in the length direction has the ability to pass through the rotating shaft at one end; the second is to pre-install two sliders with screw holes in any T-slot of an aluminum profile, align the annular rack of the hexagonal bearing seat toward the T-slot, use fastening bolts to pass through each center hole and fasten to the slider, so that the side of the aluminum profile has the ability to pass through the rotating shaft to meet specific finished product assembly design requirements.

[0053] like Figure 8 and Fig. 9 The figure is a schematic diagram of the three-dimensional structure of two toothed bases in the modular assembly assembly of the present invention. Specifically, Figure 8 The toothed base 51 shown is formed with a thin sheet-like fifth base 511 corresponding to the outer contour of the aluminum profile, and the fifth base 511 is provided with a central hole corresponding to the fastening bolt, and a buckle 513 that is compatible with the aluminum profile is integrally formed on the side surface of the fifth base facing the aluminum profile, and a ring-shaped rack 512 is integrally formed on the other side surface of the fifth base facing outward. Fig. 9 The toothed base 52 shown has a similar base 521 and annular rack 522. Both toothed bases must ensure that an annular rack is provided on one side, so that the aluminum profile can be equipped with an external device to achieve single-end radial angle adjustment, that is, the angle can be adjusted when the fastening bolt is loose, and when the required angle is reached, the fastening bolt is tightened to mesh a pair of annular racks and radially lock. The difference is that the tooth height or tooth spacing of the two annular racks is different. Figure 8 The buckle 513 of the toothed base is arranged in a straight line. Fig. 9 The buckles 523 provided on the toothed base are distributed in a cross shape.

[0054] like Fig.10The figure shows a three-dimensional structural diagram of the U-shaped seat in the modular assembly component of the present invention. It can be seen that the U-shaped seat 61 is formed with a sixth base, and the sixth base is provided with a central hole 9 that passes from the top surface to the bottom surface and corresponds to the fastening bolts passing through, the bottom surface of the sixth base is integrally formed with an annular rack 611, and the top two sides of the sixth base are integrally formed with a pair of relatively parallel ear plates 612, and the ear plates are provided with coaxially opposite mounting holes 613; the top surface of the sixth base is set to avoid the concave arc surface 614 of the external device mounted between the ear plates. When assembling the aluminum profile, the annular rack is facing the end face of the aluminum profile, and the U-shaped seat is integrally fixed to the end of the aluminum profile using the fastening bolts passing through the central hole. When assembling the peripherals, you only need to put the butt end of the peripherals between the ear plates and fix them with a specific bolt assembly through the mounting hole and the butt end. Then the peripherals at the end of the aluminum profile will have the ability to swing based on the axis of the mounting hole, or it can be understood that the aluminum profile can rotate 360 ​​degrees freely along the axis of the mounting hole relative to the peripherals. It is mainly used to assemble vehicles, booms and other highly mobile machines.

[0055] like Fig.11 , which is a three-dimensional structural diagram of the U-shaped seat used as a shock absorber in the modular assembly assembly of the present invention. Fig.10 The U-shaped seats shown are similar in height, and the only difference is the hole diameter specification of the mounting hole 623 provided on the corresponding ear plate; thereby adapting to the mounting end of the commercially available finished shock absorber to be mounted and fixed between the ear plates.

[0056] like Fig.12 The figure is a schematic diagram of the three-dimensional structure of the spur gear seat in the modular assembly component of the present invention. It can be seen that the main body of the spur gear seat 7 is an L-shaped block, and the lower part 71 of the spur gear seat is provided with a center hole 9 that passes through the top and bottom and the corresponding fastening bolts pass through. The bottom surface of the spur gear seat is integrally formed with an annular rack 711, and the upper part 72 of the spur gear seat is formed with an annular rack 721 on the side facing the axis of the center hole, and is provided with a mounting hole 722 that is coaxial with the corresponding annular rack. Here, the thickness of the upper part of the spur gear seat is less than the width of the lower part, because the spur gear seat is usually not assembled and used alone, but assembled and used in pairs, that is, the two upper parts of the spur gear seat are relatively clamped. Fig.17 The double-sided toothed ring 103 shown is assembled into an angle adjustment module through a bolt assembly of corresponding specifications passing through the assembly hole. At this time, the assembled thickness is the same as or similar to the width of the lower half of the spur gear seat. When assembling the aluminum profile, each spur gear seat is assembled with an aluminum profile in the aforementioned assembly method, and a double-sided toothed ring is taken out of the two semi-finished assemblies to be assembled into an angle adjustment module. In this way, the two spur gear seats can adjust the included angle in stages when the bolt assembly is loosened, and the included angle is locked when the bolt assembly is tightened, thereby improving the convenience of the angle adjustment operation between the two sections of aluminum profiles in the assembled product.

[0057] In addition to the above-mentioned frequently used modular housings, there are also some optional modular housings with different shapes that are used to expand the various connection modes of aluminum profiles. Fig.13 The long strip connecting seat 81 shown in the figure has a main body in the form of a rectangular block. The long strip connecting seat is provided with three center holes 9 distributed along the length direction, wherein the center holes on both sides are symmetrically arranged relative to the center hole in the middle. Moreover, the bottom surface of the long strip connecting seat is provided with an annular rack 811 coaxially corresponding to the center holes on both sides, and the top surface is provided with an annular rack 812 coaxially corresponding to the center hole in the middle. In this way, three sections of aluminum profiles can be assembled in a staggered manner on both sides based on the long strip connecting seat, and then matched with other modular seats to achieve a more complex assembly configuration. Fig.14 Another long strip connecting seat 82 shown is Fig.13 The difference shown is that the main body is thickened with a gentle transition at the location of the central hole in the middle, and the annular rack 821 is arranged at the thickened end surface.

[0058] When applied to simulated vehicle assembly and requires simulated direction control, the present invention also provides a handle seat. Fig.15 As can be seen from the three-dimensional structural diagram shown, the main body of the handle seat 101 is a hollow cylindrical tube, and a base plate corresponding to the outer contour of the aluminum profile is formed at one end, and the outer end face of the base plate is provided with an annular rack for docking with the aluminum profile or other modular seat bodies, and a center hole penetrating the base plate is provided in the center of the hollow cylindrical tube.

[0059] like Fig.16 The figure shows a three-dimensional structure diagram of a toothed hexagonal seat. Figure 6 The straight-cylinder bearing seat shown in the figure is similar, and its square bottom is also provided with an annular rack 1021 for docking with the aluminum profile. The slight difference is that the sink groove is changed to a hexagonal column groove 1022 corresponding to the hexagonal rod, and the top of the toothed hexagonal seat is cut and the side is provided with a mounting hole 1023, so as to facilitate the adjustment of the tightness and positioning when the hexagonal rod is inserted. Fig.18 A hexagonal column connector 104 is shown, and its main body is a round-headed cone, with a ring-shaped rack on the bottom surface for docking with aluminum profiles, a center hole on the top from top to bottom, and the extended part of the center hole corresponds to the hexagonal rod, so that the aluminum profiles respectively connected to the toothed hexagonal seat and the hexagonal column connector have linkage through the hexagonal rod therebetween.

[0060] In order to better understand the advantages of the modular assembly components based on square tube profiles (especially aluminum profiles) in the present invention in terms of structural design and enlightenment of mechanical structural thinking, the following introduces several finished products assembled from aluminum profiles and some modular bases therein. However, in actual applications, the assembled finished products are by no means limited to these, and as the users who participate in the design continue to assemble and try, the types and scales of the finished products will develop positively, and they will show strong practicality in many aspects.

[0061] The finished assembly can be roughly divided into two categories according to the usage status, including static equipment and dynamic driving equipment. The static equipment uses fastening bolts and sliders with screw holes as assembly parts, uses a docking base to linearly connect two sections of aluminum profiles, uses a transfer base to connect two sections of aluminum profiles to be bent at a right angle, and uses a straight tooth seat and a double-sided toothed ring to connect two sections of aluminum profiles to be bent at a desired angle. The finished assembly of the initial design is at least as follows: Fig. 20 The display stand A shown in the figure has a perforated board A1 or a whiteboard as a functional component, and is wrapped in a frame-like manner by a customized length aluminum profile and a modular base body and assembled downward to form a support base, and the support base is equipped with casters. Or it can be a special-shaped polygonal table and Fig.19 The regular polygon table (hexagonal table B) shown in the figure uses a customized desktop panel B1 as a functional component, and is assembled into a support frame of a corresponding shape by an aluminum profile with customized length and a modular seat body, and the desktop panel is covered and mounted on the top of the support frame through a transfer base. Alternatively, it is a chair (not shown), which uses a modular perforated pad as a functional component, and is assembled into a support base or a support base with armrests and backrests by an aluminum profile with customized length and a modular seat body, and the perforated pad is mounted on the support base as a seat plate and a backrest plate.

[0062] The dynamic driving equipment uses fastening bolts and sliders with screw holes as assembly parts, uses a docking base to linearly connect and extend two sections of aluminum profiles, uses a transfer base to connect the two sections of aluminum profiles into a right-angle bend, uses a spur gear seat and a double-sided gear ring to connect the two sections of aluminum profiles into a required angle bend, uses a U-shaped seat to provide the aluminum profile with the ability to swing at one end to attach peripherals or install shock absorbers, uses a spur gear seat and a double-sided gear ring to connect two sections of aluminum profiles at a required angle, or connects the end of one section of aluminum profile to the middle section side wall of another section of aluminum profile at a required angle, uses a bearing seat to provide the aluminum profile with the ability to attach bearings, and is assembled from aluminum profiles with customized lengths and modular seats into the frame and handlebars of the corresponding vehicle model, and uses perforated pads, wheels, brakes, modular battery packs, drive motors, drive pulleys, traction rods, and shock absorbers as functional components. The assembled product is at least a balance vehicle, a two-wheeled electric vehicle, a three-wheeled electric vehicle, or an electric kart. Fig.21 The figure only shows a partial frame assembly of one type of vehicle, and each functional component can be assembled and fastened using a slider with a screw hole, a fastening bolt or an external clamping device.

[0063] From the above introduction and detailed description of the modular assembly components and finished products based on square tube profiles, it can be seen that this solution is applied to teaching and daily necessities, and has outstanding substantive characteristics and significant progress. Its technical effects are as follows: 1) By flexibly configuring the number and type of each modular seat, and taking square tube profiles of different lengths and quantities according to design requirements, small furniture and display racks of various shapes and sizes can be assembled using fastening bolts, and can be disassembled and stored when there is no need for use, reflecting the strong reusability of the components.

[0064] 2) By adding and combining various conventional components such as bearings, motors, wheels, etc., it is helpful to stimulate creativity and assemble various vehicles suitable for outdoor pushing or riding. It overcomes the problems of traditional finished toy cars being damaged, rusted, taking up space and difficult to give away as children grow older. It gives modular assembly components vitality as toys, which can accompany children's growth and have long-term practicality, and continue to stimulate innovation.

[0065] In addition to the above embodiments, the present invention may also have other implementation modes. Any technical solutions formed by equivalent replacement or equivalent transformation shall fall within the scope of protection required by the present invention.
