Description

Technical Field

[0001] This utility model relates to the field of vehicle manufacturing technology, and in particular to a connection structure, a frame longitudinal beam having the connection structure, and a vehicle. Background Technology

[0002] In related technologies, existing automotive parts processing and manufacturing processes cannot achieve perfect consistency between workpiece dimensions and drawing dimensions, necessitating consideration of precision deviations. This is especially true for the relatively large overall dimensions of the vehicle frame longitudinal beams, where significant deviations are common. Furthermore, this prevents zero-to-zero clearance assembly between the various longitudinal beam segments, requiring the inclusion of certain gaps during assembly. Consequently, when connecting the longitudinal beam segments with bolts, insufficient preload may occur, leading to gaps between the segments. This hinders tight installation of the longitudinal beam segments and presents room for improvement. Utility Model Content

[0043] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0044] The following is for reference. Figures 1-11 According to the embodiment of the present utility model, the connection structure 100, by providing the mounting block 3 for plug-in installation, can reduce the assembly gap between the two first structural members 1 and second structural members 2 when the connector connects the first structural member 1 and the second structural member 2, thereby increasing the clamping force of the connector connection, and also improving the strength and durability, thereby reducing the cost.

[0045] like Figure 1 As shown, the connection structure 100 according to an embodiment of the present utility model includes: a first structural member 1, a second structural member 2, a mounting block 3, and a connector.

[0046] The first structural member 1 and the second structural member 2 are inserted into each other. That is, at least a part of the first structural member 1 can be inserted into the second structural member 2, or at least a part of the second structural member 2 can be inserted into the first structural member 1 to achieve the insertion and engagement of the two. The first structural member 1 and the second structural member 2 can be limited along the insertion direction by the connecting member so that the first structural member 1 and the second structural member 2 can be connected into a whole.

[0047] Mounting block 3 is inserted into one of the first structural member 1 and the second structural member 2; a connector passes through and connects mounting block 3, the first structural member 1, and the second structural member 2, and presses mounting block 3 towards the other of the first structural member 1 and the second structural member 2. That is, when the first structural member 1 and the second structural member 2 are connected and fixed by the connector, the connector can pass through and fix mounting block 3, the first structural member 1, and the second structural member 2, and mounting block 3 can be inserted into one of the first structural member 1 and the second structural member 2 and pressed against the other under the action of the connector.

[0048] In actual connection, the second connector 2 can be inserted into the first structural member 1, and the mounting block 3 can be inserted into the first structural member 1. Then, the connector is passed through the mounting block 3, the first structural member 1, and the second structural member 2. The connector presses against the first structural member 1, and the mounting block 3 presses against the second structural member 2 under the action of the connector. This allows the mounting block 3 to simultaneously make abutting contact with both the first and second structural members 1 and 2, thus fixing them relatively and reducing the assembly gap between them. This achieves a stable connection, ensuring a tight fit at the mating points, generating sufficient friction to enhance the anti-slip capability between the two structural members. Furthermore, the connector can be constructed as a bolt.

[0049] The mounting block 3 can be configured to flexibly adjust its relative position to the first structural component 1, meaning that the mounting block 3 and the first structural component 1 are not fixedly connected. In this case, mounting blocks 3 of different specifications can be installed on the first structural component 1 to adapt to different assembly gaps; or the mounting block 3 and the first structural component 1 can be manufactured together as a set and welded together during use to make it a whole structure. This can reduce the instability of the connection between the mounting block 3 and the first structural component 1, improve the durability of the connection position, and make the connection structure 100 suitable for different application scenarios and give full play to its fastening performance.

[0050] Meanwhile, compared to the traditional method of setting gaskets, the mounting block 3, the first structural component 1, and the second structural component 2 are fixed by inserting and connecting the mounting block 3 with the first structural component 1 using connectors. This method allows the mounting block 3 to be manufactured simultaneously with the first structural component 1, eliminating the need for developing new gasket processes or remanufacturing suitable gaskets as required by using separate gaskets. The process is simpler, which helps reduce production costs, allows for mass production, and allows the components to be welded into a single structure without causing durability issues or detachment, or any abnormal noise.

[0051] According to the connection structure 100 of this utility model embodiment, after the connector passes through the mounting block 3, the first structural member 1 and the second structural member 2, the mounting block 3 can be pressed and fixed with the first structural member 1 and the second structural member 2 at the same time. This helps to reduce the assembly gap between the first structural member 1 and the second structural member 2, making the assembly between the first structural member 1 and the second structural member 2 more compact and stable, improving the clamping force of the connector connection, and also improving the strength and durability, thereby reducing costs.

[0052] In some embodiments, such as Figure 1 and Figure 2 As shown, the first structural member 1 has an insertion cavity 11 that opens along a first direction, and at least a portion of the second structural member 2 is inserted into the insertion cavity 11. The first direction can be the length direction of the first structural member 1, meaning the insertion cavity 11 is also configured to be open at one end along the length direction of the first structural member 1, and the length direction of the second structural member 2 is also the first direction, such as... Figure 1 As shown, the insertion cavity 11 is open at the right end of the first structural member 1, that is, the left end of the second structural member 2 can be inserted into the insertion cavity 11 along its length direction, so that the two can be inserted and mated.

[0053] In this design, the mounting block 3 is inserted into the first structural member 1 along a second direction, and at least a portion of the mounting block 3 extends into the insertion cavity 11 to press against the second structural member 2. The second direction intersects with the first direction. The second direction is the direction that intersects with the first direction, which means that it forms a certain angle with the first direction, such as an angle less than 90° or perpendicular to the first direction. In a specific design, the first direction may be the length direction of the first structural member 1, and the second direction may be the height direction, width direction, or other direction that forms a small angle with the length direction of the first structural member 1.

[0054] like Figure 1 As shown, the second direction is constructed along the width direction of the first structural member 1, that is, the mounting block 3 can be inserted into the first structural member 1 along the width direction of the first structural member 1, and at least a portion of the mounting block 3 extends into the first structural member 1 to press against the second structural member 2 from the second direction. In this way, after the first structural member 1 and the second structural member 2 are inserted along the first direction and fastened by the connector, the mounting block 3 can fasten the second structural member 2 in the first structural member 1 along the second direction, that is, reduce the assembly gap between the first structural member 1 and the second structural member 2 in the second direction, thereby enabling the connector to fix the first structural member 1 and the second structural member 2 in assembly.

[0055] Therefore, by using the overlapping insertion of the mounting block 3, the first structural component 1 and the second structural component 2 in two intersecting directions, the assembly of the first structural component 1 and the second structural component 2 can be made more stable, the structure is simple, the installation is convenient, and it is also beneficial to improve the connection strength of the connection structure 100.

[0056] It should also be noted that the first structural component 1 can be a casting, and the second structural component 2 can be an aluminum profile. In this way, when the gap between the first structural component 1 and the second structural component 2 is reduced by the mounting block 3, the second structural component 2 located in the first plug-in component 1 can be directly pressed and tightened without deforming the first structural component 1, thereby enhancing the stability effect.

[0057] In some embodiments, the first structural member 1 is provided with a plug hole 12 communicating with the plug cavity 11, and the mounting block 3 is provided with a protruding plug post 31 on the side facing the first structural member 1. The plug post 31 is inserted into the plug hole 12 to extend into the plug cavity 11. That is, the plug post 31 of the mounting block 3 can extend into the plug cavity 11 through the plug hole 12 to press against and fit against the second structural member 2. In this way, the assembly gap between the connecting structures 100 can be effectively reduced, and the fastening of the connecting structures 100 can be improved.

[0058] Specifically, such as Figure 9 and Figure 11 As shown, a protruding insertion post 31 is formed on the right side of the mounting block 3, and at the same time, as Figure 4 As shown, the first structural member 1 is provided with a through-hole 12 extending along the thickness direction of its sidewall, and as... Figure 1 As shown, during actual assembly, the insertion post 31 is aligned with the insertion hole 12, which allows the insertion post 31 to extend into the insertion hole 12 along the second direction, penetrate the side wall of the first structural member 1, extend into the insertion cavity 11, and press against the second structural member 2. This reduces the assembly gap formed by the inability of the first structural member 1 and the second structural member 2 to make close contact.

[0059] Therefore, by inserting the plug 31 of the mounting block 3 into the plug hole 12 of the first structural component 1, a fixed connection can be made through the connector. The structure is simple and easy to install. It does not require a complex installation structure, which is conducive to the quick installation by the staff and improves the assembly efficiency.

[0060] In some embodiments, such as Figure 8 and Figure 10 As shown, the mounting block 3 has a first connecting hole 32 that passes through the insertion post 31, and the second structural member 2 has a second connecting hole 21. The first connecting hole 32 and the second connecting hole 21 are distributed opposite each other along the second direction and are both used for inserting the connector. That is to say, when the insertion post 31 is inserted into the insertion hole 12, the first connecting hole 32 also passes through the insertion hole 12. Thus, the connector passes through the first connecting hole 32 and the second connecting hole 21, and also passes through the insertion hole 12, thereby passing through the mounting block 3, the first structural member 1 and the second structural member 2, to achieve the fixation of the three structural members.

[0061] Since the plug-in post 31 protrudes from the surface of the mounting block 3, the depth of the first connecting hole 32 is the sum of the thickness of the mounting block 3 and the axial length of the plug-in post 31. Furthermore, the depth of the first connecting hole 32 of the plug-in post 31 can be set to be greater than the depth of the second connecting hole 21. In this way, when the connector is inserted into the first connecting hole 32, the connector can automatically align with the second connecting hole 21 under the guidance of the first connecting hole 32, and the connector can be smoothly inserted and fastened to the second connecting hole 21, which helps to improve installation efficiency.

[0062] Furthermore, the first connecting hole 32 is positioned opposite to the second connecting hole 21. The diameter of the first connecting hole 32 can be set to be the same as that of the second connecting hole 21, so that both connecting holes can be compactly installed with the connector. This also ensures that the fitting force between the connector, the mounting block 3, and the second structural member 2 is relatively balanced. As a result, structural failure caused by excessive deformation due to uneven force on each connecting hole during use can be avoided, thus improving the reliability of the structure.

[0063] In some embodiments, such as Figure 1 As shown, the first structural member 1 is also provided with a third connecting hole 13 for a connector to pass through. The third connecting hole 13 and the insertion hole 12 are respectively provided on two oppositely distributed sidewalls of the first structural member 1. The second connecting hole 21 is directly connected between the third connecting hole 13 and the insertion hole 12 along the second direction. That is, the first structural member 1 has an insertion hole 12 on one of its two oppositely distributed sidewalls along the second direction and a third connecting hole 13 on the other sidewall. After the second structural member 2 is inserted into the first structural member 1, the second connecting hole 21 is located between the insertion hole 12 and the third connecting hole 13. Thus, when the connector passes through the first connecting hole 32, it can sequentially pass through the insertion hole 12, the second connecting hole 21, and the third connecting hole 13.

[0064] It should be noted that the connector can be constructed as a bolt, which includes a threaded portion and a limiting head. The threaded portion can be sequentially inserted into the first connecting hole 32, the second connecting hole 21, and the third connecting hole 13. The limiting head can press against the side of the mounting block 3 away from the first structural member 1 to close the first connecting hole 32. A nut is provided on the outside of the third connecting hole 13 and threadedly connected to the threaded portion. As the nut is tightened, it can close the third connecting hole 13. During this process, the nut and the threaded portion gradually tighten, and the limiting head pushes the mounting block 3 towards the first structural member 1. At the same time, the insertion post 31 of the mounting block 3 gradually presses towards the second structural member 2 in the insertion hole 12, thereby gradually reducing the assembly gap between the insertion post 31 and the second structural member 2. As a result, the first structural member 1 and the second structural member 2 can be assembled more compactly through the action of the mounting block 3, improving the connection strength of the connecting structure 100 and enhancing its stability and durability.

[0065] In some embodiments, such as Figure 1 As shown, the connecting structure 100 also includes a reinforcing body 22, which is installed inside the second structural member 2. The reinforcing body 22 can be constructed as an aluminum block to strengthen the structure of the second structural member 2.

[0066] like Figure 7 As shown, the reinforcing body 22 is also provided with a through hole 221, which is distributed opposite to the second connecting hole 21 along the second direction. Thus, the connector passes through the reinforcing body 22 through the through hole 221 while passing through the second connecting hole 21. In this way, the connector connects the second structural member 2 and the reinforcing body 22 into a whole, eliminating the need for a separate connector between the two and reducing the number of connectors.

[0067] In some embodiments, a mounting cavity 23 is formed within the second structural member 2, the reinforcing body 22 is located within the mounting cavity 23, and both sidewalls of the mounting cavity 23, which are distributed opposite to each other along the second direction, are provided with second connecting holes 21. For example, Figure 1 As shown, the second structural member 2 includes two connecting plates 24 spaced apart along a second direction, with a mounting cavity 23 formed between the two connecting plates 24. That is, the reinforcing body 22 is installed between the two connecting plates 24 in the second structural member 2, and each of the two connecting plates 24 has a second connecting hole 21 arranged opposite to the through hole 221. This can prevent the force of the second structural member 2 from being concentrated on one side and improve the strength and durability of the connecting structure 100.

[0068] Specifically, such as Figure 1 As shown, the mounting cavity 23 is open on both the upper and lower sides, allowing the reinforcing body 22 to be installed from the upper side of the mounting cavity 23 into the mounting cavity 23. After installation, the connector can pass through the mounting block 3, the insertion hole 12, one connecting plate 24, the reinforcing body 2, another connecting plate 24, and the third connecting hole 13 along the second direction. Thus, the connection and fixation of each structural component can be achieved through the connector. The structure is simple, easy to install, and the forces on both sides of the second structural component 2 are relatively balanced.

[0069] In some embodiments, the outer surface of the first structural member 1 is further formed with a mounting groove 14, and the insertion hole 12 communicates between the mounting groove 14 and the insertion cavity 11. At least a portion of the mounting block 3 on the side near the first structural member 1 is accommodated in the mounting groove 14. That is, during actual installation, a portion of the mounting block 3 can be extended into the mounting groove 14, or the entire mounting block 3 can be located within the mounting groove 14, so that the mounting block 3 and the first structural member 1 can achieve embedded installation, thereby enabling the mounting block 3 and the first structural member 1 to share space in the inner and outer directions. That is, the mounting block 3 does not occupy additional assembly space in the inner and outer directions, which helps to reduce the overall structural size of the connection structure 100.

[0070] The mounting block 3 is installed and fitted with the mounting groove 14, which allows the mounting block 3 to move along the inner wall of the mounting groove 14. When the connector fastens the mounting block 3 and the first structural member 1 and the second structural member 2, the mounting block 3 can move inward along the inner wall of the mounting groove 14 to achieve a pressing effect with the first structural member 1 and the second structural member 2, thereby improving the assembly stability of the mounting block 3.

[0071] Furthermore, the mounting block 3 is provided with a plug-in post 31 on the side near the first structural member 1. As the mounting block 3 extends into the mounting recess 14, the plug-in post 31 extends into the plug-in hole 12. With the tightening of the connector, the mounting block 3 presses against the inner wall of the mounting recess 14, that is, it presses against the first structural member 1. At the same time, the plug-in post 31 approaches or directly presses against the second structural member 2. Thus, by setting the mounting block 3, the fastening effect of the connector on the first structural member 1 and the second structural member 2 can be realized, which helps to reduce the assembly gap between the first structural member 1 and the second structural member 2 and achieve compact installation.

[0072] In some embodiments, each mounting block 3 is provided with at least two insertion posts 31, and each mounting recess 14 is provided with at least two insertion holes 12, with the at least two insertion posts 31 and at least two insertion holes 12 distributed in a one-to-one correspondence. That is, each mounting block 3 can be positioned and installed with the corresponding mounting recess 14 through the insertion and engagement of at least one set of insertion posts 31 and insertion holes 12. For example, the insertion posts 31 and insertion holes 12 can be set to two, three, four or more sets, that is, the specific number can be flexibly set according to the actual fastening requirements, and is not limited to the specific number exemplified above.

[0073] In some embodiments, the first direction is perpendicular to the second direction, so that the insertion direction of the first structural member 1 and the second structural member 2 is perpendicular to the fastening direction of the mounting block 3 on the second structural member 2. In other words, when the mounting block 3 is fastened by the connector, the mounting block 3 can act on the first structural member 1 and the second structural member 2 respectively in a direction perpendicular to the insertion direction of the first structural member 1 and the second structural member 2. That is, when the mounting block 3 is fastened towards the second structural member 2 in the second direction, the assembly gap between the first structural member 1 and the second structural member 2 can be minimized to the greatest extent, thereby enhancing the assembly strength.

[0074] Therefore, in actual setup, one of the first direction and the second direction can be set as the length direction of the first structural member 1 and the other as the thickness direction, or one can be the length direction of the first structural member 1 and the other as the width direction, or one can be the thickness direction of the first structural member 1 and the other as the width direction. That is, the specific direction setting is flexible and can be selected flexibly, not limited to the direction shown in the figure, which helps to enhance the flexibility of the structural setup.

[0075] In some embodiments, the first direction is set along the length direction of the first structural member 1, that is, when the first structural member 1 and the second structural member 2 are inserted and mated in the first direction, they have a large insertion and mating length. For example, when the second structural member 2 extends into the first structural member 1, more than half of it can extend into the first structural member 1, thereby increasing the mating depth.

[0076] Meanwhile, the second direction is set along the thickness direction of the first structural member 1, which allows the mounting block 3 and the connector to achieve the fastening effect on the first structural member 1 and the second structural member 2 when they move toward the first structural member 1 with a small stroke in the second direction, which is conducive to achieving rapid fixation.

[0077] In some embodiments, there are multiple mounting blocks 3 and multiple sets of connectors. The multiple sets of connectors are matched one-to-one with the multiple mounting blocks 3, that is, the multiple mounting blocks 3 can be fastened together one-to-one by the multiple sets of connectors. Thus, there can be two, three, four or more mounting blocks 3.

[0078] Specifically, such as Figure 1 As shown, two mounting blocks 3 are provided on the outer side of the first structural member 1. The two mounting blocks 3 are spaced apart along the length of the first structural member 1. At the same time, two spaced mounting grooves 14 are provided on the left side of the first structural member 1. The two mounting blocks 3 can be installed into the two mounting grooves 14 one by one to achieve installation and cooperation at two positions.

[0079] One of the two mounting blocks 3 has four insertion posts 31 and four insertion holes 12 in the corresponding mounting groove 14 for corresponding insertion and engagement. Meanwhile, the other mounting block 3 has five insertion posts 31 and five insertion holes 12 in the corresponding mounting groove 14 for corresponding insertion and engagement. This allows for the fixed engagement of two sets of mounting blocks 3 with different shapes, resulting in higher strength and durability of the connection structure 100.

[0080] In other words, in actual design, the number of mounting blocks 3 can be set to multiple, and the shapes of the multiple mounting blocks 3 can be constructed to improve the flexibility of the installation form, realize differentiated assembly, and enhance the connection strength.

[0081] In some embodiments, multiple mounting blocks 3 are located on the same side of the first structural member 1, so that the mounting blocks 3 can be installed from the same side of the first structural member 1, which makes it easier for the operator to fasten the mounting blocks 3 and the connectors from the same side of the first structural member 1, thus improving the convenience of operation.

[0082] This utility model also proposes a longitudinal beam for a vehicle frame.

[0083] The frame longitudinal beam according to an embodiment of the present invention includes the connection structure 100 of any of the above embodiments. The frame longitudinal beam includes a front section, a middle section, and a rear section. The front section of the frame longitudinal beam can be constructed as a first structural member 1, and the middle section of the frame longitudinal beam can be constructed as a second structural member 2. This allows the front section of the middle section to at least partially extend into the front section of the longitudinal beam, and the mounting block 3 inserted into the front section of the longitudinal beam, along with a connecting member, achieves installation and engagement with the middle section of the longitudinal beam. This enables a tight assembly of the front and middle sections of the frame longitudinal beam, enhancing assembly stability.

[0084] Of course, in actual assembly, the above-mentioned connection structure 100 can be used not only between the front and middle sections of the longitudinal beam, but also for other structural components. For example, it can also be applied to the middle and rear sections of the longitudinal beam. The configuration is flexible and the application range is wider. And, attached... Figure 6 As shown, the middle section of the longitudinal beam can also be constructed as a hollow structure to form weight-reducing holes or cavities.

[0085] Therefore, by setting this connection structure 100, the longitudinal beam of the frame no longer needs to use shims or sleeves to fill the assembly gap. This avoids the force required to overcome material deformation due to material stiffness offsetting part of the bolt preload, thus preventing gaps. Instead, the connection structure 100, by using different mounting blocks 3, can adapt to different assembly gaps, improve the clamping force of the bolts, and be applied to various scenarios. At the same time, since the shim structure is eliminated, there is no need to develop new shim processes or manually make shims, thus simplifying the technical process and enabling the connection structure 100 to be mass-produced and reducing production costs. Furthermore, the mounting block 3 can be welded to the first structural component 1 to make it a whole, improving the overall strength and durability of the connection structure 100, and eliminating problems such as shim detachment and abnormal noise.

[0086] This utility model also proposes a vehicle.

[0087] The vehicle according to the embodiments of this utility model includes the connecting structure 100 or the frame longitudinal beam of any of the above embodiments. In this vehicle, after the connecting member passes through the mounting block 3, the first structural member 1, and the second structural member 2, the mounting block 3 can be simultaneously pressed and fixed to the first structural member 1 and the second structural member 2. This reduces the assembly gap between the first structural member 1 and the second structural member 2, making the assembly between them more compact and stable, and increasing the clamping force of the connecting member. Therefore, the assembly between the structural members on the vehicle is more stable, which helps to improve the strength and durability of the overall vehicle structure and enhance the overall competitiveness of the vehicle.
