Description

Technical Field

[0001] This application relates to the field of automotive modification technology, and in particular to a multi-chassis adaptive modular adapter frame and its usage method. Background Technology

[0002] Currently, non-load-bearing vehicles have a rigid frame, also known as a chassis ladder frame. The body is suspended on the frame and connected by elastic elements; vibrations from the frame are transmitted to the body through these elastic elements, and most vibrations are weakened or eliminated. In the event of a collision, the frame can absorb most of the impact force, protecting the body when driving on rough roads. Therefore, the body deformation is small, resulting in good stability and safety, and low cabin noise. However, this type of non-load-bearing body is relatively heavy, has a high center of gravity, and poor high-speed stability. Its advantages are that it has an independent ladder frame, higher chassis strength, and better resistance to bumps. In addition, even if the force on the four wheels is uneven, it is borne by the frame and will not be transmitted to the body. Therefore, it is more commonly used in SUVs and off-road vehicles.

[0003] Furthermore, the market commonly adopts a method of developing non-load-bearing chassis and platform superstructures simultaneously to achieve compatibility. During development, each chassis is designed with a specialized interface for a specific platform superstructure, ensuring uniqueness and allowing only one-to-one pairing. The platform superstructure, designed for installation, comprises all other structures of the vehicle besides the chassis.

[0004] However, due to the different needs of customer groups in the market, it is difficult for existing chassis and platform top-mounted systems to match the actual needs one by one; if a corresponding chassis and platform top-mounted system is designed for each need, the investment cost will be too large.

[0005] Therefore, in order to meet the market's different customization needs for chassis, a multi-chassis adaptable modular adapter chassis is proposed. Summary of the Invention

[0006] This application provides a multi-chassis adaptable modular adapter frame and its usage method to solve the problem in related technologies where, due to different customer needs, it is impossible to specify a one-to-one pairing between chassis and platform mounts during product development, thus avoiding repetitive design.

[0007] Firstly, a multi-chassis adaptable modular adapter chassis is provided, comprising:

[0008] Crossbars of various sizes, with at least two of each type;

[0009] Multiple beam connection structures are available, each with different limiting space dimensions, and there are multiple such structures.

[0010] The crossbar is selectively and detachably connected to two longitudinal beams according to different sizes to form the main frame of the base frame; at least two sizes of the main beam connection structure can be detachably installed on the longitudinal beam of the main frame of the base frame.

[0011] In some embodiments, the crossbar is defined as a length, and its end in contact with the longitudinal beam is provided with a first connecting screw hole;

[0012] A second connecting screw hole is provided on the side surface where the longitudinal beam contacts the end of the crossbar, and the longitudinal beam passes through the second connecting screw hole along the length direction of the crossbar; the crossbar and the longitudinal beam are connected by a first connecting bolt.

[0013] In some embodiments, the longitudinal beam is provided with transverse through holes;

[0014] The main beam connection structure includes: a U-shaped rod, the horizontal part of which passes through a transverse through hole, and the two ends of which extend downward and are provided with first screws; a pressure plate, which is provided with two mounting holes for the first screws to pass through, and is connected to the U-shaped rod by a first clamping nut;

[0015] The distance from the end of the U-shaped bar to its horizontal part is not equal for each type of beam connection structure.

[0016] In some embodiments, the longitudinal beam is provided with transverse through holes;

[0017] The beam connection structure includes:

[0018] A vertical connecting rod has a connecting ring at the top and a first screw at the bottom;

[0019] The pressure plate has two mounting holes for the first screw to pass through, and is connected to the bottom of the first clamping nut and the vertical connecting rod.

[0020] The second screw is located in the transverse through hole, and both ends of it pass through the connecting ring; the second screw is connected to the top of the vertical connecting rod through the second clamping nut;

[0021] The lengths of the second screws, vertical connecting rods, and pressure plates are not equal for each type of beam connection structure.

[0022] In some embodiments, the bottom of the longitudinal beam is provided with a shock-absorbing pad of the same length as the beam.

[0023] In some embodiments, it also includes a side-connected support beam mounting seat and an L-shaped limiting plate connected to the longitudinal beam, as well as an adapter seat connected to the upper part of the base frame via a connecting plate.

[0024] In some embodiments, the adapter is provided with an electrical adapter, an electrical limiting plate, and a mechanical limiting block.

[0025] In some embodiments, the L-shaped limiting plates are spaced apart along the length of the longitudinal beams, and their vertical portions protrude downwards to limit the lateral movement of the chassis.

[0026] Secondly, a method for using a multi-chassis adaptable modular adapter chassis is provided, which includes the following steps:

[0027] Based on the target, select the corresponding size of crossbars and beam connection structure for the chassis customization;

[0028] The crossbar and two longitudinal beams are detachably connected to form the main frame of the base frame, and the main beam connecting structure is installed on the main frame of the base frame;

[0029] The main frame of the chassis is placed on the target customized chassis and connected using the beam connection structure. Then, the platform is installed on the main frame of the chassis.

[0030] In some embodiments, when the size of the target customized chassis changes, the beam connection structure and / or crossbars of the corresponding size are replaced according to the size change to form a new multi-chassis adaptable modular transfer chassis.

[0031] The beneficial effects of the technical solution provided in this application include:

[0032] This application provides a modular adapter frame for multi-chassis adaptation and its usage method. Because the number of two longitudinal beams is fixed and various sizes of crossbars and main beam connection structures are provided, when dealing with different chassis, only the corresponding sizes of crossbars and main beam connection structures need to be replaced, eliminating the need for a complete replacement. This treats the crossbar and main beam connection structures as replaceable modules, reducing the dependence of the platform mount on the chassis, increasing the independence of the frame, improving the design response speed for multi-chassis requirements, and ensuring the overall structural accuracy of the device. This also improves the adaptation efficiency between the platform mount and the chassis and reduces chassis adaptation costs. For example, if the chassis used in this application differs from the one used in the previous matching only in its lateral dimensions, replacing the entire chassis using traditional methods would be wasteful. Therefore, the modular adapter frame for multi-chassis adaptation of this application only requires replacing the crossbars, solving the problem of inconsistent customer needs and the inability to specify a one-to-one pairing between chassis and platform mount during product development, thus avoiding repetitive design work.

[0038] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0039] This application provides a multi-chassis adaptable modular adapter frame to solve the problem in related technologies where, due to different customer needs, it is impossible to specify a one-to-one pairing between chassis and platform mounts during product development, thus avoiding repetitive design.

[0040] The above should be understood as follows: on the one hand, the modular adapter frame for multi-chassis adaptation needs to enable a single platform mount to adapt to different types of chassis, thereby improving the platform mount's ability to adapt to different types of chassis and achieving rapid adaptation of the platform mount to different types of chassis.

[0041] On the other hand, it also needs to have a modular adapter chassis that is adaptable to multiple chassis, easy to install and operate, reliable in fixing, and has good interface expandability, so as to ensure a reliable connection with the chassis during driving.

[0042] See Figure 1 To explain the first aspect above:

[0043] Crossbars 1 in various sizes, with at least two of each type;

[0044] Multiple beam connection structures 2, each with different limiting space dimensions, and there are multiple of them;

[0045] The crossbar 1 can be detachably connected to two longitudinal beams 3 according to different sizes to form the main frame of the base frame; at least two sizes of beam connection structures 2 can be detachably installed on the longitudinal beams 3 of the main frame of the base frame.

[0046] Since the number of the two longitudinal beams 3 is fixed, and various sizes of crossbars 1 and main beam connection structures 2 are provided, when dealing with different chassis, only the corresponding sizes of crossbars 1 and main beam connection structures 2 need to be replaced, without the need for a complete replacement. Thus, the crossbars 1 and main beam connection structures 2 can be regarded as replaceable modules, thereby reducing the dependence of the platform mount on the chassis, improving the independence of the chassis, increasing the design response speed for multiple chassis requirements, and ensuring the overall structural accuracy of the device. This also improves the compatibility efficiency between the platform mount and the chassis and reduces the chassis compatibility cost.

[0047] The above should be understood as follows: the only difference between the current chassis and the chassis used in the previous matching is the lateral dimension; all other dimensions are the same. Replacing the entire chassis using the traditional method would be wasteful. Therefore, the multi-chassis adaptive modular adapter frame of this application only requires replacing crossbar 1.

[0048] For example, the only difference between the current chassis and the previous one is the vertical thickness; everything else is the same. Replacing the entire chassis using traditional methods would be wasteful. Therefore, the multi-chassis adaptable modular adapter frame of this application only requires replacing the main beam connection structure 2. This allows for replacement of the corresponding modules wherever there is a difference, improving versatility. It also solves the problem of inconsistent customer needs making it impossible to specify a one-to-one match between chassis and platform mounts during product development, thus avoiding repetitive design work.

[0049] The reason why at least two sizes of beam connection structures 2 can be detached on the longitudinal beam 3 of the multi-chassis modular transfer frame is that the thickness of the chassis in the longitudinal beam 3 is basically not equal in the length direction.

[0050] In some preferred embodiments, reference Figure 1 and Figure 2 The detachable connection structure between crossbar 1 and longitudinal beam 3 is described below:

[0051] The crossbar 1 is sized as length, and its end that contacts the longitudinal beam 3 is provided with a first connecting screw hole;

[0052] A second connecting screw hole is provided on the side surface of the longitudinal beam 3 that contacts the end of the crossbar 1. The longitudinal beam 3 passes through the second connecting screw hole along the length direction of the crossbar 1. The crossbar 1 and the longitudinal beam 3 are connected by a first connecting bolt.

[0053] In some preferred embodiments, reference Figure 1 and Figure 2 The detachable connection structure between the main beam connection structure 2 and the longitudinal beam 3 will be explained below:

[0054] The first type has transverse through holes on the longitudinal beam 3;

[0055] The main beam connection structure 2 includes: a U-shaped rod, the horizontal part of which passes through a transverse through hole, and the two ends of which extend downward and are provided with first screws 200; a pressure plate 201, which is provided with two mounting holes for the first screws 200 to pass through, and is connected to the U-shaped rod by a first clamping nut;

[0056] The distance from the end of the U-shaped rod to its horizontal part is not equal for each type of beam connection structure 2.

[0057] The second type has transverse through holes on the longitudinal beam 3;

[0058] The main beam connection structure 2 includes:

[0059] The vertical connecting rod 203 has a connecting ring at the top and a first screw 200 at the bottom;

[0060] The pressure plate 201 has two mounting holes for the first screw 200 to pass through, and is connected to the bottom of the first clamping nut and the vertical connecting rod 203.

[0061] The second screw 202 is located in the transverse through hole, and both ends of it pass through the connecting ring; the second screw 202 is connected to the top of the vertical connecting rod 203 through the second clamping nut;

[0062] The lengths of the second screw 202 of each beam connection structure 2 are not equal, the lengths of the vertical connecting rods 203 are not equal, and the lengths of the pressure plates 201 are not equal.

[0063] Both of the above methods can achieve the function of detachable connection, and the size of the limiting space can be changed by replacing specific parts.

[0064] In some preferred embodiments, the second aspect above is improved by the following settings:

[0065] The multi-chassis adaptable modular transfer base frame is characterized by: including a side-connected support beam mounting seat 4 and an L-shaped limiting plate 5 connected to the longitudinal beam 3, and a transfer seat 7 connected to the upper part of the base frame main body via a connecting plate 6; the transfer seat 7 is provided with an electrical transfer seat 8, an electrical limiting plate 9, and a mechanical limiting block 10. The L-shaped limiting plates 5 are spaced apart along the length of the longitudinal beam 3, and their vertical parts protrude downwards to limit the lateral movement of the chassis. The bottom of the longitudinal beam 3 is provided with a shock-absorbing pad 11 of the same length. The shock-absorbing pad 11 can be made of oil-impregnated sleepers.

[0066] The above settings ensure simple installation, reliable fixation, good interface expandability, and a reliable connection with the chassis during operation and driving.

[0067] For example, oil-impregnated sleepers are installed between the main frame of the multi-chassis modular adapter chassis and the chassis beam to achieve buffering and shock absorption. The lateral limitation between the main frame of the chassis and the chassis is achieved by the front and rear L-shaped limiting plates 5. Then, the connection is achieved by the vertical connecting rod 203 and the first screw 200. The pressure plate 201 has two mounting holes for the first screw 200 to pass through, and is connected to the bottom of the vertical connecting rod 203 by the first clamping nut. The second screw 202 is connected to the top of the vertical connecting rod 203 by the second clamping nut. This ensures that the connection between the main frame of the chassis and the chassis beam can be achieved after clamping.

[0068] The platform mount is securely connected to the adapter 7 via connecting bolts. An electrical limit plate is installed to electrically limit the platform mount's rotation on the base frame. Adjusting the relative position between the platform mount's buffer and the mechanical limit block 10 achieves mechanical limiting when the platform mount rotates on the base frame's main frame. An electrical adapter plug is installed on the electrical adapter to enable communication control between the control terminal and the platform mount. Additionally, an extended support beam is installed on the support beam mounting base 4 as needed to facilitate the fixing of the decking and toolbox on the base frame.

[0069] The above platform is equipped with existing equipment and structures. Among them, the adapter 7, electrical adapter 8, electrical limit plate 9 and mechanical limit block 10 are all existing structures and will not be described in detail again.

[0070] This application also proposes a method for using a multi-chassis adaptable modular adapter chassis, which includes:

[0071] Based on the target, select the corresponding size of the crossbar 1 and the beam connection structure 2 for the chassis customization;

[0072] The crossbar 1 and the two longitudinal beams 3 are detachably connected to form the main frame of the base frame, and the main beam connecting structure 2 is installed on the main frame of the base frame;

[0073] The main frame of the chassis is placed on the target customized chassis and connected using the main beam connection structure 2. Then, the platform is installed on the main frame of the chassis.

[0074] When the dimensions of the target customized chassis change, the main beam connection structure 2 and / or crossbar 1 of the corresponding dimensions are replaced to form a new multi-chassis adaptable modular transfer base frame. Of course, for ease of construction and installation, horizontal or vertical plates can be added to the main frame of the base frame later.

[0075] This method reduces the dependence of the platform mount on the chassis, increases the independence of the chassis, improves the design response speed for multiple chassis requirements, and better ensures the overall structural accuracy of the device. It also improves the adaptation efficiency between the platform mount and the chassis, and reduces chassis adaptation costs. It achieves simple installation and operation, reliable fixation, good interface expandability, and ensures reliable connection with the chassis during operation and driving.
