Description

Technical Field

[0001] This invention relates to the field of automotive parts technology, and in particular to a multi-functional automotive gantry. Background Technology

[0002] With the continued deepening of the policy to lift restrictions on pickup truck road rights in 2025, many regions have relaxed traffic restrictions, and new energy pickup trucks enjoy more preferential policies. Pickup trucks inherently combine comfort and transportation functions, offering greater versatility. As a core modification component, the multi-functional roll bar for pickup trucks combines roll protection, cargo securing, and aesthetic enhancement, making it an essential part of pickup truck vehicles. However, existing roll bars suffer from several drawbacks: First, traditional one-piece or welded structures occupy significant transport space, have high manufacturing costs, and are inconvenient to maintain and replace. Second, most products lack quick-release functionality, enclosing the vertical space of the pickup truck's tailgate after installation, affecting the loading of bicycles, large cargo, etc. Third, their functionality is limited, only meeting basic protection needs and lacking practical functions such as storage and extended mounting. Fourth, some designs with warning functions only add a single brake light, offering limited warning effectiveness in inclement weather and lacking adjustability to accommodate different cargo box sizes. Furthermore, existing quick-release structures often rely on non-standard connectors, resulting in high costs and poor versatility, failing to meet users' personalized modification and economic needs. These problems prevent existing roll bars from simultaneously achieving safety, practicality, and flexibility, thus limiting the multi-functional use of pickup trucks.

[0003] Of course, some masts do have quick-release structures, but existing quick-release structures mostly rely on non-standard connectors, which are costly and have poor versatility, making it difficult to meet users' personalized modification and economic needs. These problems prevent existing masts from simultaneously achieving safety, practicality, and flexibility, thus limiting the multi-functional use of pickup trucks. This invention aims to solve the technical problems of existing pickup truck masts, such as inconvenient transportation and storage, cumbersome assembly and disassembly, limited functionality, and poor adaptability. It provides a modular design, convenient quick-release, multi-functional, and highly adaptable pickup truck mast to meet multiple needs such as safety protection, flexible loading, and personalized expansion. Summary of the Invention

[0004] To overcome the shortcomings of the prior art, the present invention provides a multi-functional gantry frame for automobiles.

[0005] The technical solution adopted by this invention to solve its technical problem is: This invention provides a multi-functional gantry frame for automobiles, including a frame body for installation at a preset external position; the frame body includes a quick-release base, a support base, and a connector for connecting the quick-release base and the support base, the connector being detachably located at one end of the support base along its length, and the connector intersecting the support base to form an angle of 90-120°.

[0006] Preferably, the support base is arranged in a strip shape, with two connectors. The two connectors are respectively located at both ends of the support base along its length. The distance between the two connectors near the support base is no greater than the distance between the two connectors away from the support base. By setting the support base as a strip foundation and assembling connectors at both ends, and limiting the connectors at both ends to an flared layout with the distance between the far end and the distance between the near end being greater, the span of the stress point is lengthened in the longitudinal direction and the width of the support base is widened in the transverse direction. This significantly enhances the anti-tilting ability and structural stability of the frame under load, and avoids swaying or overturning caused by concentrated force.

[0007] Preferably, there are two quick-release bases, each located at the end of one of the two connectors furthest from the support. Each quick-release base has a pad at the end furthest from the support. The quick-release base is held against a predetermined external position by the pad and fixed thereby by external bolts. The pads at the ends of the two connectors increase the friction contact area, buffer installation stress, and fill minor unevenness in the installation surface. Combined with bolt locking, this achieves the dual effect of ensuring both the stability and flatness of the base installation while allowing for quick assembly and disassembly when needed.

[0008] Preferably, both ends of the connector in the length direction are provided with slots for external bolts to pass through. The connector is detachably connected to the quick-release base and the support base respectively via external bolts. By providing slots at both ends of the connector as bolt connection channels, it provides an adjustable margin for the relative position between the quick-release base and the support base, overcoming the problem of misalignment of holes caused by manufacturing tolerances or installation position deviations, and realizing flexible alignment during installation and convenience of subsequent disassembly and maintenance.

[0009] Preferably, the connector includes a first outer rod and a first inner rod, which are respectively mounted on the base and the support. The first inner rod is slidably mounted on the first outer rod. Both the first inner rod and the first outer rod have arrayed slots along their length for external bolts to pass through. The first inner rod and the first outer rod are fixed by external bolts. The telescopic sleeve structure formed by the first outer rod and the first inner rod, along with the arrayed slots, is locked in place. This allows for flexible adjustment of the distance between the support and the quick-release base, enabling the same gantry frame to adapt to external installation positions and vehicle-mounted items of different widths or sizes, significantly improving the product's versatility and applicability.

[0010] Preferably, the first inner rod is provided with a scale bar. By setting the scale bar on the first inner rod, it provides an intuitive and accurate numerical reference when adjusting the extension and retraction length of the connecting parts, eliminating the adjustment error caused by visual inspection, realizing the consistency of length when adjusting at both ends simultaneously, and ensuring the squareness and left-right balance of the overall assembly of the frame.

[0011] Preferably, the frame is provided in two sets, which are arranged in parallel with a gap. The frame is equipped with connecting components, and the two sets of frames are connected by the connecting components. By arranging the two sets of frames in parallel with a gap and using the connecting components for lateral connection, a three-dimensional frame-type load-bearing structure is constructed, which transforms the original linear support of a single frame into planar support, greatly improving the overall rigidity and load-bearing area of ​​the entire gantry system, and realizing the stable support of large or irregularly shaped items.

[0012] Preferably, the connecting assembly includes a second outer rod and a second inner rod slidably disposed on the second outer rod. The ends of the second outer rod and the second inner rod that are far apart are respectively disposed on the connectors at one end of the length direction of the two sets of frames. By designing the connecting assembly as a telescopically adjustable structure of the second outer rod and the second inner rod, and fixing its two ends to the connectors of the two sets of frames respectively, it plays the role of simultaneously adjusting the span between the two sets of frames when connecting them laterally, realizing flexible adjustment in the width direction, and further enhancing the adaptability of the frame structure to items of different sizes.

[0013] Preferably, the second inner rod is provided with a scale bar. By setting the scale bar on the second inner rod, a quantitative benchmark is provided when adjusting the interval width of the two sets of frames. This avoids the deviation of parallelism or inconsistency of width on both sides caused by adjustment by feeling. It enables the two sets of frames to be adjusted to the required working width quickly and accurately, ensuring the construction efficiency and structural symmetry.

[0014] Preferably, a storage frame is detachably provided on the support base. The storage frame is mounted on the support base via quick-release bolts. By detachably installing the storage frame on the support base using quick-release bolts, the load-bearing function of the gantry frame is expanded without changing the main structure of the gantry frame. This allows the frame to quickly switch between a simple basic support function and a storage mode with enclosure and storage functions, meeting the diverse loading needs of users.

[0015] The beneficial effects of this invention are: 1. Adopting a modular quick-disassembly design, each component can be quickly assembled and disassembled using bolts and T-bolts. A single person can complete the assembly or disassembly in 5 minutes, reducing the transportation and storage volume by 60% and lowering transportation and maintenance costs.

[0016] 2. It integrates a high-mounted brake light, fog warning light strip, and spare tire fixing function. At the same time, it supports the mounting of various expansion accessories through a standard interface T-slot, solving the problem of the single function of traditional gantry frames and meeting the needs of off-road, freight and other scenarios.

[0017] 3. The connector adopts an inward angle design and telescopic structure, combined with an adjustable quick-release base, to adapt to different pickup truck tail box sizes. Cargo binding holes and anti-slip bases improve cargo stability and prevent shaking during transportation.

[0018] 4. The main body is made of aluminum alloy profiles and die-cast aluminum connectors, which reduces the overall weight while ensuring structural strength (load-bearing capacity up to 400kg). The corrosion-resistant coating treatment improves adaptability to extreme environments and extends service life. Attached Figure Description

[0023] Reference Figures 1 to 5A multi-functional gantry for automobiles includes a frame 1, which is used to be installed in a preset position on the outside. The frame 1 includes a quick-release base 11, a support base 12, and a connector 13 for connecting the quick-release base 11 and the support base 12. The connector 13 is detachably provided at one end of the support base 12 along its length. The connector 13 and the support base 12 intersect to form an angle of 90-120°.

[0024] With the above-described structural design, in use, this technical solution designs the frame 1 as a combination structure including a quick-release base 11, a support base 12, and a connector 13. The connector 13 is detachably installed at the end of the support base 12, and the two intersect to form an angle of 90-120°. This allows the quick-release base 11 to be firmly installed in the preset position, and the force direction and load-bearing capacity of the support base 12 to be optimized by utilizing this specific angle range. This achieves the ability to flexibly adjust or replace different specifications of the support base 12 according to actual usage needs to expand its multi-functionality, while ensuring the structural connection is stable and the reliable support effect for vehicle-mounted items, and facilitating disassembly and transportation.

[0025] Specifically, the support base 12 is arranged in a strip shape, and there are two connectors 13. The two connectors 13 are respectively located at both ends of the support base 12 along its length. The distance between the two connectors 13 near the end of the support base 12 is no greater than the distance between the two connectors 13 away from the support base 12. By setting the support base 12 as a strip foundation and assembling connectors 13 at both ends, and limiting the connectors 13 at both ends to an flared layout with "the distance between the far end and the distance between the near end", the span of the stress point is lengthened in the longitudinal direction and the width of the support bottom is widened in the transverse direction. This significantly enhances the anti-tilting ability and structural stability of the frame 1 under load, and avoids swaying or overturning caused by concentrated force.

[0026] The support base 12 is preferably made of die-cast aluminum alloy, with an M8 tapping hole specification; the exposed part of the connecting plate of the quick-release base 11 is made of stainless steel and is fastened to the pickup truck tail box rail with T-bolts. The connector 13 has a T-slot and can slide to connect two get-out-of-trouble plate brackets. The load-bearing capacity of the connector 13 can reach 50kg / piece. It is worth noting that 50kg / piece is a static load, or it can carry a tool shovel and two 5KG fuel tanks.

[0027] All components in this technical solution can be treated with corrosion-resistant coatings, such as coating or electroplating.

[0028] The support base 12 has end caps 121 at both ends along its length, and the end caps 121 are formed by cutting and bending the ends along the length of the support base 12.

[0029] Of course, when using T-bolts, the locking torque or anti-loosening can be achieved by adding anti-loosening nuts or locking washers.

[0030] Specifically, there are two quick-release bases 11, which are respectively located at the ends of the two connectors 13 away from the support base 12. The ends of the quick-release bases 11 away from the support base 12 are provided with pads 111. The quick-release bases 11 are abutted against the preset external position by the pads 111 and are fixed to the preset external position by external bolts. The quick-release bases 11 with pads 111 are respectively provided at the ends of the two connectors 13. The pads 111 abut against the preset external position first, which increases the friction contact surface, buffers the installation stress, and fills the minor unevenness of the installation surface. Combined with bolt locking, the dual effect of ensuring the firmness and flatness of the base installation and achieving quick disassembly and assembly when needed is achieved.

[0031] The quick-release base 11 is an arc-shaped structure that fits into the pre-set track of the pickup truck's tail box. The quick-release base is connected to the pre-set track of the pickup truck's tail box by T-bolts and is further tightened by longitudinal bolts.

[0032] The pad 111 is an anti-slip rubber pad with a thickness of 1.5mm. The anti-slip rubber pad is used to improve the fit and anti-slip effect.

[0033] Specifically, both ends of the connector 13 along its length are provided with slots 131 for external bolts to pass through. The connector 13 is detachably connected to the quick-release base 11 and the support base 12 via external bolts. By providing slots 131 at both ends of the connector 13 as bolt connection channels, it provides an adjustable margin for the relative position between the quick-release base 11 and the support base 12, overcoming the problem of misalignment of holes caused by manufacturing tolerances or installation position deviations, and realizing flexible alignment during installation and convenience for subsequent disassembly and maintenance.

[0034] Specifically, the connector 13 includes a first outer rod 132 and a first inner rod 133. The first outer rod 132 and the first inner rod 133 are respectively disposed on the base 11 and the support seat 12. The first inner rod 133 is slidably disposed on the first outer rod 132. The first inner rod 133 and the first outer rod 132 are provided with an array of slots 131 along the length direction. The slots 131 are used for external bolts to pass through. The first inner rod 133 and the first outer rod 132 are fixed by external bolts. The telescopic sleeve structure formed by the first outer rod 132 and the first inner rod 133 is locked in conjunction with the array of slots 131, which enables the spacing between the support seat 12 and the quick-release base 11 to be flexibly adjusted. This realizes the ability of the same gantry frame to adapt to external installation positions and vehicle-mounted items of different widths or sizes, significantly improving the versatility and applicability of the product.

[0035] The first outer rod 132 and the first inner rod 133 can achieve stepless height adjustment from 0 to 26 cm to adapt to the loading needs of goods of different heights.

[0036] Preferably, the first outer rod 132 and the first inner rod 133 are made of automotive wheel hub grade aluminum alloy, with an outer rod cross-section of 96x56mm and an inner rod cross-section of 82x43mm, and an inward angle of 10 degrees.

[0037] Specifically, the first inner rod 133 is provided with a scale bar. By setting the scale bar on the first inner rod 133, it provides an intuitive and accurate numerical reference when adjusting the extension length of the connecting piece 13, eliminating the adjustment error caused by visual inspection, realizing the consistency of length when adjusting at both ends simultaneously, and ensuring the squareness and left-right balance of the overall assembly of the frame 1.

[0038] Specifically, the frame 1 has two sets, which are arranged in parallel with each other. The frame 1 is equipped with a connecting component 2, and the two sets of frame 1 are connected by the connecting component 2. By arranging the two sets of frame 1 in parallel with each other and connecting them laterally with the connecting component 2, a three-dimensional frame-type load-bearing structure is constructed, which transforms the original linear support of a single frame into a planar support, greatly improving the overall rigidity and load-bearing area of ​​the entire gantry system, and realizing the stable support of large or irregularly shaped items.

[0039] The two sets of frame bodies 1 have the same structure and are symmetrically distributed. The structural material of the two sets of frame bodies 1 is partly or entirely made of automotive wheel hub-grade aluminum alloy profiles, and they are set with an inward angle of 10-12 degrees. That is, the actual manifestation is that the connector 13 and the support base 12 intersect to form an angle of 90-100°.

[0040] Specifically, the connecting component 2 includes a second outer rod 21 and a second inner rod 22 slidably disposed on the second outer rod 21. The ends of the second outer rod 21 and the second inner rod 22 that are far apart are respectively disposed on the connectors 13 at one end of the length direction of the two sets of frames 1. By designing the connecting component 2 as a telescopically adjustable structure of the second outer rod 21 and the second inner rod 22, and fixing its two ends to the connectors 13 of the two sets of frames 1 respectively, it plays the role of simultaneously adjusting the span between the two sets of frames when connecting them laterally, realizing flexible adjustment in the width direction, and further enhancing the adaptability of the frame structure to items of different sizes.

[0041] Both the second outer rod 21 and the first outer rod 132 are hollow square profiles. The second inner rod 22 is slidably disposed inside the second outer rod 21. The upper, lower, left and right outer walls of the second outer rod 21 have T-shaped grooves, which can be expanded in all directions. The first outer rod 132 is similarly configured.

[0042] The second outer rod 21 and the first outer rod 132 can achieve stepless adjustment of 0-10cm in the front and rear to adapt to the needs of different pickup truck models.

[0043] Specifically, the second inner rod 22 is equipped with a scale bar. By setting the scale bar on the second inner rod 22, it serves as a quantitative benchmark when adjusting the interval width of the two sets of frames 1, avoiding the deviation of parallelism or inconsistency of width on both sides caused by adjustment by feeling. It enables the two sets of frames to be quickly and accurately adjusted to the required working width, ensuring the construction efficiency and structural symmetry.

[0044] The scale bars are recessed on the second inner rod 22 and the first inner rod 133.

[0045] Specifically, a storage frame is detachably provided on the support base 12. The storage frame is installed on the support base 12 via external quick-release bolts. By detachably installing the storage frame on the support base 12 using quick-release bolts, the load-bearing function of the gantry frame is expanded without changing the main structure of the gantry frame. This allows the frame 1 to quickly switch between a simple basic support function and a storage mode with enclosure and storage functions, thus meeting the diverse loading needs of users.

[0046] The storage box is lined with a net to hold a spare tire and other items; the outer side of the connector 13 of the two frames 1 is also provided with a standard interface T-slot, which can slide to connect the escape board bracket, tool box and other expansion accessories, and can be extended externally by T-bolts.

[0047] Of course, the support base 12 is also equipped with a standard interface T-slot.

[0048] In other embodiments, after the connector 13 is raised, it can be higher than the roof of the vehicle to facilitate the installation of a roof tent. A high-mounted brake light and a warning light are installed on the connector 13 located at the rear of the pickup truck. The connecting component 2 can be telescopically adjusted and can also be adapted to short wheelbase pickup truck models. It is 10 degrees inward to make the overall force distribution more reasonable. With the strength of the vehicle body, it can bear a larger total load, ultimately making the maximum load capacity of the roll frame 400kg.

[0049] Specifically, T-shaped grooves are provided on the connector 13, support base 12 and connecting assembly 2 to allow for sliding connection of extension accessories, including a get-out-of-trouble board bracket, toolbox or fuel tank.

[0050] The first inner rod and the first outer rod can be infinitely adjusted in height from 0 to 26 cm, and the second inner rod and the second outer rod can be infinitely adjusted forward and backward from 0 to 10 cm. The inner rod is equipped with a scale bar for adjustment reference.

[0051] A high-mounted brake light and a fog warning light can be installed on the connector.

[0052] End caps are provided at both ends of the support base to protect the groove and the ends of the support structure.

[0053] The support base 12, connector 13 and connecting assembly 2 are preferably made of automotive wheel hub grade aluminum alloy profiles, which have lightweight, high strength and corrosion resistance; the exposed connecting plate of the quick-release base 11 is made of stainless steel to improve wear resistance and corrosion resistance; each component can be anodized, electrophoretically coated or coated with anti-corrosion coating to enhance service life.

[0054] The included angle between the connector 13 and the support base 12 is designed to be 90-120°. The connectors 13 at both ends are arranged in an flared manner to increase the longitudinal force span and the lateral support width, thereby enhancing the anti-tilting ability. The quick-release base 11 is equipped with an anti-slip rubber pad 111 (1.5mm thick) to increase the friction surface and buffer the installation stress, so as to achieve stable installation and quick disassembly. The end cap 121 in the length direction of the support base 12 protects the end and the T-slot, while increasing the uniformity of force distribution.

[0055] Both the frame 12 and the connector 13 are equipped with standard T-slots, which can be used to install extension accessories such as off-road board brackets, tool boxes, and fuel tanks; the support base 12 can be detached to install a storage frame, which can hold a spare tire or outdoor tools for storage; the connector 13 can be raised to the top of the vehicle roof for easy installation of roof tents, brake lights and warning lights, and is compatible with different pickup truck models and cargo heights.

[0056] The quick-release base 11 is fastened to the vehicle's tailgate rail with T-bolts and can be used with anti-loosening nuts or locking washers to enhance stability; the connector 13 has slots 131 at both ends, which can be strip-shaped to provide adjustable bolt allowance to accommodate manufacturing tolerances and installation deviations, achieving flexible alignment and convenient maintenance; the frame and connecting components can be quickly disassembled, stored and transported, suitable for outdoor mobile operations.

[0057] A single connector can withstand a static load of up to 50kg, supporting tools, fuel tanks, or other outdoor equipment; the overall gantry system can withstand a maximum load of up to 400kg (considering the vehicle body support and the connection strength of the two sets of frames); the T-slot expansion interface can bear the total weight of accessories, ensuring the overall structure is stable.

[0058] The support base 12 and connecting component 2 are compatible with different pickup truck models and tailgate rail specifications; the frame, connectors and expansion accessories can be flexibly disassembled or adjusted according to usage needs to achieve multi-scenario use; all adjustable or telescopic parts are designed to be easy to operate and have clear scales to ensure installation efficiency and operation accuracy.

[0059] The modular design of this invention allows for flexible combination of different components according to user needs. All connection structures meet the requirements for disassembly and replacement. Those skilled in the art can adjust component parameters according to actual usage scenarios to achieve personalized adaptation.

[0060] The above descriptions provide one or more embodiments in conjunction with specific details, but do not imply that the specific implementation of the present invention is limited to these descriptions. Any methods or structures that are similar to or identical to those of the present invention, or any technical deductions or substitutions made based on the concept of the present invention, should be considered within the scope of protection of the present invention.
