In addition, the terms "first" and "second" are only used to distinguish in the description and have no special meaning.

[0043] like Figures 1 to 3 As shown, an embodiment of the first aspect of the present invention provides a fixing device, which includes a first fixing assembly 1 and a second fixing assembly 2. The first fixing assembly 1 includes a first fixing plate 11, and the first fixing plate 11 is provided with a first connection structure 12 and a third connection structure 13. The first connection structure 12 can be connected to the first part 3, and the third connection structure 13 can be connected to the second part 4 and / or the first part 3. The first part 3 and the second part 4 can be arranged on both sides of the first fixing plate 11. The second fixing assembly 2 is arranged on the first fixing assembly 1, and the second fixing assembly 2 includes a second fixing plate 21 and a second support member 22. The second support member 22 is arranged between the first fixing plate 11 and the second fixing plate 21. The second support member 22 can support the second fixing plate 21 from the surface of the first fixing plate 11 to form an installation channel 23. The installation channel 23 can be used for the installation of the first part 3. The second fixing plate 21 is provided with a second connection structure 24, and the second connection structure 24 can be used for the connection of the third part 5.

[0044] The first fixing assembly 1 refers to the basic part of the fixing device, which at least includes a first fixing plate 11, on which a first connection structure 12 and a third connection structure 13 are provided, and the first connection structure 12 is designed to establish a fixed connection with the first part 3, so as to ensure that the first part 3 can be stably installed on one side of the first fixing plate 11. The third connection structure 13 has a similar function to the first connection structure 12, but at the same time it can also be connected to the second part 4, and can be achieved without interfering with the first part 3, so that the first part 3 and the second part 4 can be fixed on both sides of the first fixing plate 11 respectively, reducing the interference between the first part 3 and the second part 4, and improving the applicability of the fixing device.

[0045] The second fixing assembly 2 may be located above the first fixing assembly 1, and at least includes a second fixing plate 21 and a second support member 22. The function of the second support member 22 is to separate the second fixing plate 21 from the first fixing plate 11 to form an installation channel 23, that is, the second support member 22 is a structure connecting the first fixing plate 11 and the second fixing plate 21, and plays a supporting and separating role, ensuring that there is a certain space between the second fixing plate 21 and the first fixing plate 11, that is, the installation channel 23. The second fixing plate 21 is located above the installation channel 23, and a second connecting structure 24 is provided thereon for connecting the third part 5, so as to allow the third part 5 to be installed without interfering with the first and second parts 4 on the first fixing assembly 1, thereby increasing the flexibility and versatility of the fixing device.

[0046] The function of the installation channel 23 is to allow the first part 3 to be directly installed on the first fixing plate 11 through the installation channel 23 without colliding or interfering with the second fixing component 2, thereby ensuring smooth and safe installation of the first part 3.

[0047] In this way, the present embodiment arranges the first connection structure 12 and the third connection structure 13 on the first fixing plate 11, so that the first part 3 and the second part 4 can be connected to the two sides of the first fixing plate 11 respectively, and the second support member 22 supports the second fixing plate 21 from the surface of the first fixing plate 11, and the third part 5 is installed on the second fixing plate 21, thereby avoiding the interference problem that may be caused by direct contact between the first part 3, the second part 4 and the third part 5, and is particularly suitable for the scene of fixing parts that need to be avoided. The second support member 22 forms an installation channel 23 between the first fixing plate 11 and the second fixing assembly 2, and the second support member 22 supports the second fixing plate 21 from the surface of the first fixing plate 11, so as to adapt to the height difference between the first part 3 and the third part 5, without the need for additional parts or complex adjustment mechanisms, and simplifying the fixing process.

[0048] The design of the installation channel 23 not only solves the height difference problem, but also provides space for the first part 3 to avoid. For example, when the first part 3 needs to be staggered with the third part 5 in space, the installation channel 23 can reduce the obstruction of the second fixing plate 21 to the installation of the first part 3. The second connection structure 24 on the second fixing plate 21 can be connected to the third part 5, so that the installation of the third part 5 does not need to be directly in contact with the first fixing component 1, and can be completed through the second fixing component 2, which simplifies the installation sequence and steps when fixing multiple parts and improves assembly efficiency. The second support member 22 not only provides support, but also ensures the stability of the second fixing plate 21, avoids possible shaking or displacement of the second fixing plate 21 during use, and enhances the overall stability of the fixing device. The design of the installation channel 23 also ensures the stable installation of the first part 3, and reduces the vibration and displacement caused by the excessive gap between adjacent parts.

[0049] The presence of the installation channel 23 makes the installation of the first part 3 more convenient, without the need for complicated positioning and adjustment steps. When the installation channel 23 is similar to the outline size of the first part 3, it can also guide the first part 3. At the same time, the independent setting of the second connection structure 24 also simplifies the connection operation of the third part 5, improving the work efficiency of the user. The first connection structure 12, the second connection structure 24 and the third connection structure 13 in the design of the fixing device can flexibly adapt to the fixing requirements of various parts, whether it is a simple plane fixation or a complex spatial layout, and it is easy to find a suitable fixing method, which solves the technical problems that the fixing device in the related art cannot effectively fix parts with height differences and specific avoidance structures, and there are high complexity and poor stability during installation and use.

[0050] Optionally, the second support member 22 can be designed as a lifting structure with adjustable height, and the distance between the second fixing plate 21 and the first fixing plate 11 can be changed by adjusting the height of the second support member 22, so as to adapt to the fixing requirements of the first part 3 and the third part 5 with different height differences. For example, the second support member 22 can be in the form of a threaded rod or a telescopic rod, and its length can be adjusted by rotation or stretching. The third connecting structure 13 can be designed as a structure with one or more connection points. For example, multiple third connecting structures 13 can be set on the first fixing plate 11 to facilitate the simultaneous fixing of multiple second parts 4, or to strengthen the connection between the second part 4 and the first fixing plate 11 at multiple points. This can improve the versatility of the fixing device and enable it to adapt to more complex combinations of parts.

[0051] The shape of the second fixing plate 21 can be optimized to better match the installation requirements of the third part 5. For example, the second fixing plate 21 can be designed to have a special contour shape, such as a groove, a protrusion or a special angle, to ensure the accurate positioning and stable connection of the third part 5. The second connection structure 24 on the second fixing plate 21 can be of various types, such as a threaded hole, a slot, a hinge or a magnetic adsorption member. This diversified connection method can provide a wider range of fixing options and is suitable for third parts 5 of different materials and shapes. A positioning system, such as laser positioning, magnetic positioning or mechanical positioning pins, can also be integrated in the first fixing component 1 and / or the second fixing component 2 to help quickly and accurately locate and install the corresponding parts during the installation process. For example, a positioning system such as magnetic positioning can be set at the first connection structure 12, the second connection structure 24 and the third connection structure 13 to improve the convenience of the connection operation. The material of the fixing device can be optimized to adapt to different use environments and strength requirements. For example, the fixing device can use high-strength alloy materials, composite materials or materials with corrosion resistance and high temperature resistance to enhance the durability and reliability of the fixing device.

[0052] The fixture can be modularly designed, that is, the first fixing component 1 and the second fixing component 2 can be independently disassembled and replaced. This design allows the fixture to be flexibly configured according to specific application scenarios, improving its maintainability and adaptability. The fixture is modularized through the separate fixing design of the first fixing component 1 and the second fixing component 2. This design allows the user to add or remove corresponding fixing components as needed to adapt to the fixing of parts of different numbers and sizes, thereby improving the versatility and customizability of the fixture.

[0053] like Figures 1 to 3 As shown, in some embodiments, the third connection structure 13 includes a main connection hole 131 and / or a positioning column 132, the main connection hole 131 passes through the first fixing plate 11, and the main connection hole 131 can be connected to the first part 3 and / or the second part 4. The positioning column 132 is arranged on a side of the first fixing plate 11 away from the second fixing component 2, and the positioning column 132 can be connected to the second part 4.

[0054] Among them, the main connection hole 131 is one or more hole structures that penetrate the first fixing plate 11, and its diameter and position are designed according to specific application requirements. The main function of the main connection hole 131 is to provide a direct connection point, so that the second part 4, or the first part 3, can pass through this hole to establish a mechanical connection with the first fixing plate 11 through bolts, pins or other fixing structures. The advantage of this connection method lies in its stability. The first part 3 and / or the second part 4 are directly connected to the first fixing plate 11 through the hole, which reduces the shaking and displacement during the movement, and is suitable for scenes that need to bear large loads or require high-precision positioning.

[0055] The positioning column 132 is a protruding structure arranged on the side of the first fixing plate 11 away from the second fixing component 2. Its shape can be cylindrical, but it can also be designed into other shapes as needed. The main function of the positioning column 132 is to provide a positioning reference for the second part 4 to ensure that the second part 4 can be more accurately aligned with the first fixing plate 11 during the installation process. Unlike the main connection hole 131, the positioning column 132 is not used for direct mechanical connection, but plays a role in auxiliary positioning. This design is particularly suitable for application scenarios that require rapid installation and disassembly, as well as situations where high part position accuracy is required.

[0056] With such a configuration, in this embodiment, whether directly connected through the main connection hole 131 or assisted by the positioning column 132, the third connection structure 13 can ensure a stable connection between the second part 4 and the first fixing plate 11. In particular, the through-design of the main connection hole 131 provides an additional fixing point, which can withstand greater torque and load, and improve the strength and stability of the fixing structure. The third connection structure 13 can not only connect the second part 4, but also the first part 3. The fixing device has multi-part compatibility, and one fixing device can fix multiple parts at the same time, which reduces the number of brackets in the assembly process, simplifies the assembly process, and improves production efficiency.

[0057] The presence of the positioning column 132 provides an accurate positioning reference for the second part 4, ensuring the accuracy of the part installation position, which is particularly important for application scenarios that require high-precision positioning, such as the assembly of precision instruments or mechanical equipment. Since the third connection structure 13 includes a variety of main connection holes 131 and positioning columns 132, it provides greater flexibility and adaptability for the use of the fixing device. Different application scenarios can select appropriate connection methods according to actual needs, so that the fixing device can adapt to more diverse part fixing needs.

[0058] Optionally, the main connection hole 131 can be designed to have different sizes or shapes according to the fixing requirements of different first parts 3 or second parts 4, for example, a conical hole, an elliptical hole or a plurality of round holes of standard sizes can be used to adapt to fixing structures of different diameters or connectors of special shapes, thereby improving the compatibility and flexibility of the connection. The positioning column 132 can be designed to have an adjustable height or position, for example, using a threaded column or a telescopic column to adapt to second parts 4 of different thicknesses or positions, allowing the user to adjust the positioning column 132 according to actual needs to ensure accurate installation and fixation of the second part 4.

[0059] The positioning post 132 can be designed as a detachable and replaceable component so that the user can select a suitable positioning post 132 for installation according to the specific shape and size of the second part 4. This modular design improves the adaptability and maintenance convenience of the fixture. In addition to the cylindrical shape, the cross-sectional profile of the positioning post 132 can also be designed as a square, a triangle or other shapes to match the specific groove or hole on the second part 4 to provide a more precise positioning effect.

[0060] A reinforcement structure, such as an annular reinforcement rib or a mesh reinforcement beam, can be designed around the main connection hole 131 to improve the structural strength of the first fixing plate 11 in the hole area to prevent deformation or cracking of the material around the hole when subjected to a large load. For the second part 4 made of metal, the positioning column 132 can be designed to be a magnetic material, which fixes the second part 4 by magnetic adsorption, provides preliminary positioning, and then performs final fixation through mechanical connection. This design is particularly suitable for rapid assembly and disassembly scenarios.

[0061] like Figures 1 to 3 As shown, in some embodiments, the second fixing plate 21 is located above the third connection structure 13, and the second fixing plate 21 includes a first sub-plate 211 and a second sub-plate 212, and the first sub-plate 211 and the second sub-plate 212 are respectively arranged on both sides of the main connection hole 131. At least two second support members 22 may be provided, and the at least two second support members 22 are respectively arranged between the first sub-plate 211 and the first fixing plate 11 and between the second sub-plate 212 and the first fixing plate 11.

[0062] The separation design between the first sub-plate 211 and the second sub-plate 212 is to better match the main connection hole 131, reducing the interference of the second fixing plate 21 on the first part 3 and the third part 5 when they are fixed. The setting of the two sub-plates allows the first part 3 or other connecting parts to approach the main connection hole 131 from both sides or above, making the fixation more flexible and efficient. In order to ensure the stability and strength of the structure, at least two second support members 22 should be respectively arranged between the first sub-plate 211 and the first fixing plate 11 and between the second sub-plate 212 and the first fixing plate 11. The multi-point support design not only improves the load-bearing capacity of the fixing device, but also reduces the structural risks that may be caused by a single support point by dispersing the pressure.

[0063] This embodiment significantly improves the overall structural stability of the fixing device through the multiple point distribution of the second support member 22 and the symmetrical design of the first sub-plate 211 and the second sub-plate 212, and can maintain good mechanical properties under heavy loads, reducing the risk of structural deformation or failure. The separation between the second fixing plate 21 and the first fixing plate 11 and the use of the main connection hole 131 facilitate the installation of the first part 3. The first part 3 can approach the main connection hole 131 from both sides or from above without being hindered by the second fixing plate 21, which greatly simplifies the assembly process and improves assembly efficiency. The design of the first sub-plate 211 and the second sub-plate 212 allows more fixing points, i.e., the second connection structure 24, to be set on the second fixing plate 21, and more parts, such as the third part 5, can be fixed on the second fixing plate 21, improving the versatility and part fixing ability of the fixing device. By arranging the first sub-plate 211 and the second sub-plate 212 on both sides of the main connecting hole 131, and arranging the second support member 22 between these sub-plates and the first fixing plate 11, the fixing device realizes efficient use of space, which not only reduces the overall volume of the fixing device, but also provides the possibility for structural avoidance between parts, so that the fixing device can realize complex fixing tasks in a limited space.

[0064] Optionally, the shape and size of the first sub-plate 211 and the second sub-plate 212 can be optimized according to the size and position of the main connection hole 131. For example, the first sub-plate 211 and the second sub-plate 212 can be designed to have arc-shaped edges or inner grooves at the bottom to facilitate the alignment and installation of the first part 3 and reduce friction and resistance during installation. The second support member 22 can be designed to be a material with a certain elasticity, such as spring steel or rubber. This elastic support can absorb some vibrations and shocks, improve the anti-seismic performance of the fixing device, and is particularly suitable for applications that need to maintain stability in a dynamic environment.

[0065] In order to improve the mechanical strength of the second fixing plate 21, reinforcing ribs or support beams may be added to the first sub-plate 211 and the second sub-plate 212, especially around the second connection structure 24, to prevent deformation of the second connection structure 24 due to force. In order to prevent the third part 5 from sliding on the second fixing plate 21, anti-slip patterns or coatings may be provided on the first sub-plate 211 and the second sub-plate 212 to increase the friction between the third part 5 and the second fixing plate 21, thereby ensuring that the third part 5 is firmly fixed.

[0066] like Figures 1 to 3 As shown, in some embodiments, in the arrangement direction of the first sub-board 211 and the second sub-board 212 , the extension length of the first sub-board 211 is equal to or greater than the extension length of the second sub-board 212 .

[0067] The layout direction of the first sub-panel 211 and the second sub-panel 212 refers to the arrangement and layout direction of the first sub-panel 211 and the second sub-panel 212 in space, which may be horizontal or vertical, depending on the design of the fixture and the application scenario.

[0068] The extension length refers to the longitudinal dimension of the first sub-plate 211 and the second sub-plate 212 in the layout direction, that is, the distance from one end thereof in contact with the second support member 22 to the other end. Considering the length difference between the first sub-plate 211 and the second sub-plate 212, the sizes of the first sub-plate 211 and the second sub-plate 212 are limited.

[0069] In this way, when the extension length of the first sub-plate 211 is greater than that of the second sub-plate 212, the first sub-plate 211 provides a larger support area on one side of the fixture, which helps to enhance the structural stability of the side, especially when subjected to asymmetric loads or lateral forces, the fixture can be better balanced. The longer first sub-plate 211 can provide more fixing points, such as the position of the second connecting structure 24, which enables the fixture to fix larger parts or multiple parts, thereby enhancing the versatility and practicality of the fixture. Different extension lengths allow the fixture to adapt to parts of different sizes, especially for those parts with different length requirements in the layout direction. This design can provide a more flexible installation and fixing scheme. By adjusting the extension lengths of the first sub-plate 211 and the second sub-plate 212, the space occupied by the fixture can be minimized while ensuring the fixing effect, especially in an application environment with limited space. In some application scenarios, when the fixture needs to accurately position the third parts 5 of different lengths, the difference in extension lengths of the first sub-plate 211 and the second sub-plate 212 can be used as a positioning reference to ensure that the parts can be accurately aligned during the installation process.

[0070] Optionally, the first sub-plate 211 and the second sub-plate 212 can be designed as a retractable structure, for example, by means of a slide rail, a telescopic rod or a threaded adjustment structure, the user can adjust the extension length of the first sub-plate 211 and the second sub-plate 212 as needed to accommodate parts of different sizes, providing more flexible fixing options. In some cases, the extension length of the first sub-plate 211 can be designed to be stepped, that is, in the layout direction, its length varies at different positions, forming multiple support planes, which can provide support points for parts of different heights, thereby enhancing the load-bearing capacity and structural stability of the fixing device.

[0071] The extension lengths of the first sub-plate 211 and the second sub-plate 212 can be adjusted proportionally according to the expected load distribution. For example, on the side where the expected load is heavier, the first sub-plate 211 can be designed to be longer to provide a larger support area, while on the side where the load is lighter, the length of the second sub-plate 212 can be relatively reduced to save materials and space. In the case where there is no need to fix large parts, the first sub-plate 211 and the second sub-plate 212 can be designed as a foldable structure, connected by a hinge or a folding rod, so that it can be folded, reducing space occupancy and facilitating the storage and transportation of the fixture.

[0072] like Figures 1 to 4 As shown, in some embodiments, a first support member 14 is disposed at the bottom of the first fixed plate 11, the first connecting structure 12 and the third connecting structure 13 are disposed on both sides of the first support member 14, and the first fixed plate 11 is provided with a plate section of the second fixed component 2 and is surrounded by the first support member 14 to form a fixing groove 15, and the fixing groove 15 can be connected to the second part 4.

[0073] The first support member 14 is arranged at the bottom of the first fixing plate 11, and is used to support the entire fixing device to ensure that it can remain stable during use. There can be multiple first support members 14, which are distributed at the bottom of the first fixing plate 11 according to the load and stability requirements, and are usually columnar or plate-shaped structures. The fixing groove 15 is a space formed by the plate section of the second fixing component 2 arranged on the first fixing plate 11 and the first support member 14, and is used to accommodate and fix the second part 4. The design of the fixing groove 15 can adapt to second parts 4 of different shapes and sizes, and provide a stable fixing effect.

[0074] In this way, the arrangement of the first support member 14 enhances the bottom support of the first fixing plate 11, improves the overall stability and load-bearing capacity of the fixing device, and can maintain good structural performance, especially when subjected to a large load. The first connecting structure 12 and the third connecting structure 13 are respectively used to fix different types of parts, providing a variety of fixing methods, which can adapt to the fixing requirements of different parts and improve the versatility and flexibility of the fixing device. The design of the fixing groove 15 can not only accommodate the second part 4, but also can achieve accurate positioning and stable fixation of the second part 4 through its specific structure, such as cooperation with the third connecting structure 13, thereby reducing the positional deviation and instability of the second part 4 during the fixing process. By arranging the first connecting structure 12 and the third connecting structure 13 on both sides of the first support member 14 and forming the fixing groove 15, the fixing device can more efficiently utilize limited space, which not only reduces the volume of the fixing device, but also improves its application potential in a small space. The combination of the first fixing plate 11, the first connecting structure 12, the third connecting structure 13 and the fixing groove 15 enables the fixing device to fix multiple parts at the same time, thereby improving its practicality in a complex assembly environment.

[0075] Optionally, the first support member 14 can be designed to be height-adjustable, for example, through a threaded adjustment or telescopic mechanism, allowing the user to adjust the distance between the first fixing plate 11 and the base according to actual needs, thereby adapting to the fixing requirements of parts of different heights. The first support member 14 can be composed of multiple independent support points to disperse the load and enhance the stability of the overall structure. These support points can be detachable so that they can be flexibly adjusted according to the use environment and load size. Integrating a position sensor, a pressure sensor or a vibration sensor on the first fixing plate 11 or the first support member 14 to monitor the fixing state of the second part 4 and the working condition of the fixing device is helpful to adjust the fixing strategy in real time or warn of potential problems.

[0076] Reinforcing ribs or support beams can be added around the fixing groove 15 to improve its bearing capacity and structural strength. This reinforced design is more advantageous for fixing devices that need to fix heavier parts or are used in high vibration environments. Positioning points are engraved or marked on the first fixing plate 11 to assist in the precise alignment of the first part 3 and the second part 4. Especially in application scenarios that require alignment of multiple parts, this design can significantly improve the accuracy and efficiency of assembly. The first fixing plate 11 can be designed as a modular structure. By adding or reducing plate segments and expanding or reducing the size of the fixing groove 15 to accommodate second parts 4 of different sizes, the flexibility and versatility of the fixing device are enhanced.

[0077] like Figures 2 to 4 As shown, in some embodiments, the number of positioning posts 132 is multiple, and multiple positioning posts 132 are arranged in the fixing groove 15, and multiple positioning posts 132 are arranged at intervals along the extension direction of the first support member 14. In this way, by arranging multiple positioning posts 132 inside the fixing groove 15, the second part 4 can be more accurately positioned when fixed, avoiding the assembly error caused by the offset of the second part 4, and improving the accuracy of the overall assembly. The interval distribution of multiple positioning posts 132 not only provides multiple positioning points, but also plays a role in structural reinforcement, especially when carrying a large load, it can effectively disperse stress, reduce the deformation of the fixing groove 15, and enhance the structural stability of the fixing device. The number and distribution of positioning posts 132 can be adjusted according to the size and shape of different second parts 4. This design flexibility enables the fixing device to adapt to a wider range of part fixing requirements and improves its applicability in different application scenarios. The design of multiple positioning posts 132 makes the positioning process of the second part 4 simpler, without complicated adjustment steps, and only needs to place the second part 4 in the fixing groove 15, and the positioning posts 132 can automatically complete the positioning, thereby improving the assembly efficiency. The uniform distribution of the locating posts 132 reduces the risk of wear and damage to individual locating posts 132 , extending the service life of the fixture, thereby reducing long-term maintenance and replacement costs.

[0078] like Figure 1 and Figure 4 As shown, in some embodiments, the first fixing component 1 also includes a first reinforcing plate 16, which is arranged between the first fixing plate 11 and the first support member 14; and / or, the second fixing component 2 also includes a second reinforcing plate 25, which is arranged between the first sub-plate 211 and the second support member 22, and / or, between the second sub-plate 212 and the second support member 22.

[0079] Among them, the first reinforcing plate 16 is arranged between the first fixing plate 11 and the first support member 14, and is used to strengthen the connection between the two, improve the overall structural strength of the first fixing assembly 1, and prevent structural deformation or damage under force or vibration conditions. A plurality of first reinforcing plates 16 can be provided, and the plurality of first reinforcing plates 16 are arranged at intervals in the extension direction of the first support member 14. For example, the plurality of first reinforcing plates 16 can be evenly arranged at equal intervals. The second reinforcing plate 25 can be arranged between the first sub-plate 211 and the second support member 22, or between the second sub-plate 212 and the second support member 22, and plays a role in structural reinforcement, ensuring the stability and reliability of the second fixing assembly 2 when bearing loads.

[0080] In this way, the arrangement of the first reinforcing plate 16 and the second reinforcing plate 25 significantly improves the structural strength of the fixing device, so that the fixing device can withstand a larger load, and improves its stability and durability under various working conditions. By adding corresponding reinforcing plates between the first fixing plate 11 and the first support member 14, and between the second fixing plate 21 and the second support member 22, vibration can be effectively suppressed, the displacement of corresponding parts or fixation failure caused by vibration can be reduced, and the accuracy and reliability of the fixing device can be improved. The design of the first reinforcing plate 16 and the second reinforcing plate 25 can reduce the requirements for the material thickness of the first fixing plate 11 and the first support member 14, and the second fixing plate 21 and the second support member 22, and achieve the strength requirements through structural optimization, save materials, and reduce production costs. The rigidity and stability of the first fixing component 1 and the second fixing component 2 can also be further fine-tuned by adjusting the thickness, material or layout of the first reinforcing plate 16 and the second reinforcing plate 25 to meet the specific needs of different application scenarios. In a working environment with high temperature or large temperature difference, the first reinforcing plate 16 and the second reinforcing plate 25 can alleviate the influence of thermal stress on the first fixing component 1 and the second fixing component 2, and prevent structural damage caused by thermal expansion and contraction.

[0081] Optionally, the first reinforcing plate 16 and the second reinforcing plate 25 are designed as a structure with adjustable thickness or position. For example, the first fixing plate 11 and the second support member 22 may be detachably connected to the first reinforcing plate 16 by bolt connection or clamping, and the first fixing plate 11 and the first support member 14 may be provided with a plurality of connection positions for the first reinforcing plate 16 to be connected. The second fixing plate 21 and the second support member 22 may also be detachably connected to the second reinforcing plate 25 by bolt connection or clamping, and the second fixing plate 21 and the second support member 22 may be provided with a plurality of connection positions for the second reinforcing plate 25 to be connected, so that the user can adjust the layout of the first reinforcing plate 16 and the second reinforcing plate 25 as needed to optimize the load-bearing capacity and structural stability of the fixing device. The material of the first reinforcing plate 16 and the second reinforcing plate 25 may be a high-strength composite material, such as carbon fiber, glass fiber reinforced plastic, etc., to significantly improve the tensile strength and bending stiffness while maintaining lightweight, which is suitable for environments requiring high load and light weight.

[0082] Optionally, both the first reinforcing plate 16 and the second reinforcing plate 25 can be designed as triangular plates. The height of the first reinforcing plate 16 gradually increases from the free end of the first fixing plate 11 to the connection position of the first fixing plate 11 with the first support member 14, which can improve the structural strength and reduce the space occupied by the first reinforcing plate 16. The height of the second reinforcing plate 25 gradually increases from the free end of the first sub-plate 211 to the connection position of the first sub-plate 211 with the second support member 22. Similarly, the height of the second reinforcing plate 25 gradually increases from the free end of the second sub-plate 212 to the connection position of the second sub-plate 212 with the second connecting member, which can improve the structural strength and form an arched avoidance structure under the first sub-plate 211 and the second sub-plate 212 to avoid the installation of the first part 3 and the connection operation of the third connecting structure 13.

[0083] like Figures 1 to 3 As shown, in some embodiments, the first connection structure 12 includes a plurality of first auxiliary connection holes 121, and the plurality of first auxiliary connection holes 121 are arranged at intervals on the first fixing plate 11; and / or the second connection structure 24 includes a plurality of second auxiliary connection holes 241, and the plurality of second auxiliary connection holes 241 are arranged at intervals on the second fixing plate 21. The spacing between two adjacent first auxiliary connection holes 121 is equal to or greater than the spacing between two adjacent second auxiliary connection holes 241.

[0084] Among them, the first auxiliary connection hole 121 is a hole set on the first fixing plate 11, which is used to pass bolts, pins or other connecting parts to fix the first fixing plate 11 with the external structure or the first part 3. The interval arrangement of multiple first auxiliary connection holes 121 provides multiple connection points, which enhances the reliability and stability of the connection. The second auxiliary connection hole 241 is a hole set on the second fixing plate 21, which is used for connection with the external structure or the third part 5. Similar to the first auxiliary connection hole 121, the distribution design of multiple second auxiliary connection holes 241 can provide multiple connection points to ensure the stable connection of the second fixing plate 21.

[0085] In this way, the present embodiment can provide multiple fixing points by setting a plurality of corresponding first auxiliary connection holes 121 and second auxiliary connection holes 241 distributed at intervals on the first fixing plate 11 and the second fixing plate 21, which significantly enhances the connection stability and reliability between the fixing device and the external structure or the corresponding parts. The multiple settings of the two auxiliary connection holes allow the user to select the appropriate connection point according to actual needs, improve the applicability and flexibility of the fixing device, and can adapt to various different connection requirements and environments. The spacing between two adjacent first auxiliary connection holes 121 is equal to or greater than the spacing between two adjacent second auxiliary connection holes 241, which not only allows the fixing device to adapt to external structures of different sizes by changing the hole spacing, but also increases the rigidity of the connection by increasing the hole spacing in applications requiring high stability. The design of multiple auxiliary connection holes makes it easier to replace or adjust the corresponding connection position when the fixing device needs maintenance or adjustment, reducing maintenance costs and downtime. By increasing the connection points, the load of a single connector can be dispersed, thereby improving the bearing capacity and durability of the overall connection system and reducing the risk of failure caused by damage to the connector.

[0086] In this embodiment, in order to adapt to different types of connectors, the shapes and sizes of the first auxiliary connection hole 121 and the second auxiliary connection hole 241 can be designed to be adjustable, such as oval, rectangular or with internal threads, to meet the needs of different connectors such as bolts, pins, rivets, etc. In addition, shockproof materials can be added around the holes or shock-absorbing structures can be designed, such as rubber pads or bellows, to absorb and disperse external impacts and protect the fixing device and connector from damage.

[0087] like Figures 1 to 3 As shown, in some embodiments, there are multiple second fixing components 2, and the multiple second fixing components 2 are arranged at intervals on the first fixing plate 11, and / or the multiple second fixing components 2 are stacked in the vertical direction of the first fixing plate 11.

[0088] Among them, multiple second fixing components 2 means that the number of second fixing components 2 is not limited to one, and there can be multiple second fixing components 2 to meet the needs of fixing parts of different numbers or sizes, thereby improving the flexibility and application range of the fixing device. Optionally, multiple second fixing components 2 are arranged at intervals on the first fixing plate 11, which means that the distribution of multiple second fixing components 2 on the first fixing plate 11 is spaced apart, rather than continuous. This layout can ensure that each second fixing component 2 has enough space to avoid mutual interference, and also facilitates the positioning and fixing of parts.

[0089] Optionally, a plurality of second fixing components 2 are stacked in the vertical direction of the first fixing plate 11, which means that the second fixing components 2 can be stacked in the vertical direction of the first fixing plate 11, which means that the second fixing components 2 can be set at different heights of the first fixing plate 11 to meet the needs of fixing parts with height differences.

[0090] By setting a plurality of second fixing components 2, this embodiment can fix a plurality of parts at the same time, improve the fixing ability of the fixing device, and is suitable for application scenarios where a plurality of parts or components need to be fixed. The interval setting of the second fixing components 2 and the stacking setting of the second fixing components 2 enable the fixing device to adapt to parts of different sizes and heights, and improve the flexibility and versatility of the device. The plurality of second fixing components 2 can disperse the load when fixing the parts, avoid the problem of excessive force on a single point, and improve the stability and safety of the fixing device. The second fixing components 2 are arranged at intervals on the first fixing plate 11, and the second fixing components 2 are stacked in the vertical direction, so that the space can be reasonably utilized, and effective part fixation can be achieved even in a limited space. Through the preset interval and stacking layout, the assembly of the second fixing components 2 can be faster and more accurate, reducing the adjustment and positioning time during the assembly process. The flexible layout of the second fixing components 2 enables the fixing device to adapt to more complex assembly environments, such as the fixing of multi-layer structures, the fixing of specific space restrictions, etc. The setting of a plurality of second fixing components 2 can enhance the overall structural strength of the fixing device and improve its reliability under high load or vibration environments by increasing the connection points and dispersing the load.

[0091] Optionally, the installation position of the second fixing component 2 can be adjusted. For example, the second fixing component 2 and the first fixing plate 11 can be connected by a detachable method such as bolts or a sliding connection driven by a cylinder or a hydraulic cylinder. The user can adjust the spacing between adjacent second fixing components 2 as needed to adapt to the fixing requirements of parts of different sizes and shapes.

[0092] like Figure 1 and Figure 5 As shown, the X direction shown in the figure is a schematic diagram of the first direction, the Y direction is a schematic diagram of the third direction, and the Z direction is a schematic diagram of the second direction.

[0093] An embodiment of the second aspect of the present invention provides a vehicle, comprising a first part 3, a second part 4, a third part 5 and a fixing device in any of the above embodiments, wherein the first part 3 and the second part 4 are arranged on a first fixing component 1, and the third part 5 is arranged on a second fixing component 2, the first part 3 and the third part 5 can be extended along a first direction, the first part 3 and the third part 5 have a height difference in the second direction, the second part 4 can be extended along a third direction, and the first direction, the second direction and the third direction intersect with each other, for example, the first direction, the second direction and the third direction can be perpendicular to each other.

[0094] Among them, the first part 3 is a part of the vehicle, which can be extended along the first direction to form a specific height difference with other parts. The first direction is usually the lateral or longitudinal direction of the vehicle, depending on the layout of the parts. The first part 3 can be inserted into the installation channel 23, and the first part 3 can be fixedly arranged on the first fixing plate 11 through the first connecting structure 12 and / or the third connecting structure 13. The second part 4 is another part of the vehicle, which can be extended along the third direction, and the third direction intersects with the first direction and the second direction in pairs, so that the layout of the second part 4 forms a three-dimensional interlaced relationship with the first part 3 and the third part 5 to meet the complex space requirements in the vehicle. The second part 4 can be fixedly arranged on the first fixing plate 11 through the third connecting structure 13. The third part 5 is another component of the vehicle, which has a height difference with the first part 3 in the second direction. The first part 3 and the third part 5 are in different positions in the vertical direction of the vehicle, and a fixing device is required to ensure a stable connection between them. The third part 5 can be fixedly arranged on the second fixing plate 21 through the second connecting structure 24. The fixing device is used to form a stable and adjustable connection between different parts, and is particularly suitable for situations where there is structural avoidance and height difference between parts.

[0095] In this way, by using the fixture in the vehicle, the three-dimensional layout of the first part 3, the second part 4 and the third part 5 in space can be achieved, and even if the spatial relationship between the parts is complex, a good fixing effect can be ensured, thereby improving the flexibility of vehicle design and space utilization efficiency. The fixture can adapt to the height difference between the first part 3 and the third part 5 in the second direction, such as the vertical direction, so as to facilitate a stable connection between parts of different heights. The fixture supports the parts to be extended in different directions, namely the first direction, the second direction and the third direction. This directional fixing ability enables the fixture to cope with various dynamic loads when the vehicle is running, and improves the reliability and stability of the connection between the parts. The use of the fixture strengthens the connection between the internal parts of the vehicle, thereby improving the strength and rigidity of the overall structure of the vehicle, and helps the vehicle maintain the structural integrity under complex driving conditions such as bumpy roads and high-speed driving. The fixture can be used as a layout tool to help optimize the arrangement of the internal parts of the vehicle, so that the parts can achieve efficient and stable connection even in a limited space, which helps to improve the performance of the vehicle and reduce energy consumption. The precise positioning ability of the fixture and the highly compatible fixing method can improve the accuracy of the vehicle assembly process, ensure the correct alignment between the parts, thereby reducing assembly errors and improving the overall quality of the vehicle.

[0096] Since the above-mentioned fixing device is included, the vehicle of the embodiment of the present invention has all the advantages and beneficial effects of the above-mentioned embodiments, which will not be described in detail here.
