Technical Field

[0001] This invention relates to the field of fixing equipment technology, and more particularly to a fixing device and a vehicle. Background Technology

[0002] In vehicle manufacturing, fixing devices are an indispensable component, used to ensure stable connection and positioning between parts.

[0003] In related technologies, fixing devices are often designed as a single frame structure, which limits their fixing methods and application scope. For example, when it is necessary to fix two parts with a height difference and specific structural avoidance, or in some application scenarios, when the two parts also need to be fixed to another structural component, a single frame structure is difficult to meet the fixing requirements, and it is also highly complex and unstable during installation and use. Summary of the Invention

[0004] The purpose of this invention is to provide a fixing device and a vehicle to solve the technical problems in the related art where fixing devices cannot effectively fix parts with height differences and specific avoidance structures, and where there is high complexity and poor stability during installation and use.

[0005] To achieve this objective, the present invention adopts the following technical solution:

[0006] In a first aspect, the present invention provides a fixing device, the fixing device comprising:

[0007] The first fixing component includes a first fixing plate, on which a first connecting structure and a third connecting structure are provided. The first connecting structure can be connected to a first part, and the third connecting structure can be connected to a second part and / or the first part. The first part and the second part can be respectively disposed on both sides of the first fixing plate.

[0008] A second fixing component is disposed on the first fixing component. The second fixing component includes a second fixing plate and a second support member. The second support member is disposed between the first fixing plate and the second fixing plate. The second support member can support the second fixing plate away from the surface of the first fixing plate to form an installation channel. The installation channel can be used to install the first part. The second fixing plate is provided with a second connecting structure, which can be used to connect a third part.

[0009] In one embodiment, the third connection structure includes:

[0010] A main connecting hole, which penetrates the first fixing plate, is capable of connecting to the first part and / or the second part; and / or,

[0011] A positioning post is disposed on the side of the first fixing plate opposite to the second fixing component, and the positioning post can be connected to the second part.

[0012] In one embodiment, the second fixing plate is located above the third connecting structure, and the second fixing plate includes a first sub-plate and a second sub-plate, which are respectively disposed on both sides of the main connecting hole;

[0013] The second support member may be provided in at least two, and the at least two second support members are respectively provided between the first sub-plate and the first fixed plate and between the second sub-plate and the first fixed plate.

[0014] In one embodiment, in the arrangement direction of the first and second sub-plates, the extension length of the first sub-plate is equal to or greater than the extension length of the second sub-plate.

[0015] In one embodiment, a first support member is provided at the bottom of the first fixing plate, the first connecting structure and the third connecting structure are respectively provided on both sides of the first support member, and the plate segment of the first fixing plate provided with the second fixing component and the first support member surrounds to form a fixing groove, the fixing groove being able to connect with the second part.

[0016] In one embodiment, there are multiple positioning posts, which are disposed in the fixing groove and spaced apart along the extension direction of the first support member.

[0017] In one embodiment, the first fixing component further includes a first reinforcing plate disposed between the first fixing plate and the first support member; and / or,

[0018] The second fixing component further includes a second reinforcing plate, which is disposed between the first sub-plate and the second support member, and / or between the second sub-plate and the second support member.

[0019] In one embodiment, the first connection structure includes a plurality of first auxiliary connection holes, which are spaced apart on the first fixing plate; and / or,

[0020] The second connection structure includes a plurality of second auxiliary connection holes, which are spaced apart on the second fixing plate;

[0021] The distance between two adjacent first auxiliary connecting holes is equal to or greater than the distance between two adjacent second auxiliary connecting holes.

[0022] In one embodiment, there are multiple second fixing components, which are spaced apart on the first fixing plate, and / or, the multiple second fixing components are stacked in the vertical direction of the first fixing plate.

[0023] Secondly, the present invention provides a vehicle including a first part, a second part, a third part, and a fixing device according to any of the above embodiments. The first part and the second part are disposed on a first fixing assembly, and the third part is disposed on a second fixing assembly. The first part and the third part extend along a first direction, and the first part and the third part have a height difference in a second direction. The second part can extend along a third direction, and the first direction, the second direction, and the third direction intersect each other.

[0024] The beneficial effects of this invention are as follows:

[0025] The present invention provides a fixing device and vehicle. The fixing device, by setting a first fixing component and a second fixing component, and by setting a first connecting structure and a third connecting structure on the first fixing plate, allows a first part and a second part to be respectively connected to opposite sides of the first fixing plate.

This is particularly suitable for fixing parts that require avoidance. An installation channel is formed between the first fixing plate and the second fixing component through the second support member. The second support member supports the second fixing plate away from the surface of the first fixing plate, thus accommodating the height difference between the first and third parts. No additional parts or complex adjustment mechanisms are required, simplifying the fixing process. The device is simple in structure, easy to install and use, and convenient to operate.

[0039] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, and not all of the structures.

[0040] In the description of this invention, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly.

[0041] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0042] In the description of this embodiment, the terms "upper," "lower," "left," and "right," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the present invention. In addition, the terms "first" and "second" are used only for distinction in 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 component 1 and a second fixing component 2. The first fixing component 1 includes a first fixing plate 11, on which a first connecting structure 12 and a third connecting structure 13 are provided. The first connecting structure 12 can be connected to a first part 3, and the third connecting structure 13 can be connected to a second part 4 and / or the first part 3. The first part 3 and the second part 4 can be respectively disposed on both sides of the first fixing plate 11. The second fixing component 2 is disposed on the first fixing component 1, and includes a second fixing plate 21 and a second support member 22. The second support member 22 is disposed between the first fixing plate 11 and the second fixing plate 21, and can support the second fixing plate 21 away from the surface of the first fixing plate 11 to form an installation channel 23 for the first part 3 to be installed. The second fixing plate 21 is provided with a second connecting structure 24 for the third part 5 to be connected.

[0044] The first fixing component 1 refers to the basic part of the fixing device, including at least a first fixing plate 11. The first fixing plate 11 is provided with a first connecting structure 12 and a third connecting structure 13. The first connecting structure 12 is designed to establish a fixed connection with the first part 3, ensuring that the first part 3 can be stably installed on one side of the first fixing plate 11. The third connecting structure 13 has a similar function to the first connecting structure 12, but it can also be connected to the second part 4 without interfering with the first part 3. This allows the first part 3 and the second part 4 to be fixed on opposite sides of the first fixing plate 11, reducing interference between the first part 3 and the second part 4 and improving the applicability of the fixing device.

[0045] The second fixing component 2 can be located above the first fixing component 1, and includes at least 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, forming 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, playing a supporting and separating role, ensuring that there is a certain space between the second fixing plate 21 and the first fixing plate 11, i.e., the installation channel 23. The second fixing plate 21 is located above the installation channel 23, and is provided with a second connecting structure 24 for connecting a third part 5, which facilitates the installation of the third part 5 without interfering with the first and second parts 4 on the first fixing component 1, increasing the flexibility and versatility of the fixing device.

[0046] The purpose of the mounting channel 23 is to allow the first part 3 to be directly mounted on the first fixing plate 11 without colliding or interfering with the second fixing component 2, thus ensuring the smoothness and safety of the installation of the first part 3.

[0047] With this configuration, this embodiment, by setting a first connecting structure 12 and a third connecting structure 13 on the first fixing plate 11, allows the first part 3 and the second part 4 to be connected to both sides of the first fixing plate 11 respectively, and the second support member 22 to support the second fixing plate 21 away from the surface of the first fixing plate 11. The third part 5 is installed on the second fixing plate 21, avoiding interference problems that may be caused by direct contact between the three parts 3, 4 and 5. This is particularly suitable for fixing scenarios where parts need to be avoided. The first fixing plate 11 and the second fixing assembly 2 form an installation channel 23 through the second support member 22. The second support member 22 supports the second fixing plate 21 away from the surface of the first fixing plate 11, thereby accommodating the height difference between the first part 3 and the third part 5. No additional parts or complex adjustment mechanisms are required, simplifying the fixing process.

[0048] The design of the mounting channel 23 not only solves the height difference problem but also provides space for the first part 3 to avoid obstruction. For example, when the first part 3 needs to be spatially offset from the third part 5, the mounting channel 23 can reduce the obstruction of the second fixing plate 21 on the installation of the first part 3. The second connecting structure 24 on the second fixing plate 21 can be used to connect the third part 5, so that the installation of the third part 5 does not need to directly contact the first fixing component 1, but can be completed through the second fixing component 2, simplifying the installation sequence and steps when fixing multiple parts and improving assembly efficiency. The second support 22 not only provides support but also ensures the stability of the second fixing plate 21, avoiding possible shaking or displacement of the second fixing plate 21 during use and enhancing the overall stability of the fixing device. The design of the mounting channel 23 also ensures the stable installation of the first part 3, reducing vibration and displacement caused by excessive gaps between adjacent parts.

[0049] The presence of mounting channel 23 makes the installation of the first part 3 more convenient, eliminating the need for complex positioning and adjustment steps. When the mounting channel 23 is similar in size to the outline of the first part 3, it can also guide the first part 3. Simultaneously, the independent design of the second connecting structure 24 simplifies the connection operation of the third part 5, improving user efficiency. The first connecting structure 12, the second connecting structure 24, and the third connecting structure 13 in the fixing device design can flexibly adapt to the fixing needs of various parts, whether it is simple planar fixing or complex spatial layout, facilitating the finding of a suitable fixing method. This solves the technical problems in related technologies where fixing devices cannot effectively fix parts with height differences and specific avoidance structures, and where there is high complexity and poor stability during installation and use.

[0050] Optionally, the second support member 22 can be designed as a height-adjustable lifting structure. 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, thereby accommodating the fixing needs of the first part 3 and the third part 5 with different height differences. For example, the second support member 22 can be a threaded rod or a telescopic rod, with its length adjusted by rotation or extension. The third connecting structure 13 can be designed with one or more connection points. For example, multiple third connecting structures 13 can be provided on the first fixing plate 11 to simultaneously fix multiple second parts 4, or to provide multi-point reinforcement connections between the second part 4 and the first fixing plate 11. This improves the versatility of the fixing device, enabling 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 with a special contour shape, such as a groove, a protrusion, or a special angle, to ensure accurate positioning and secure connection of the third part 5. The second connecting structure 24 on the second fixing plate 21 can take various types, such as threaded holes, slots, hinges, or magnetic adsorption components. This diverse connection method provides a wider range of fixing options suitable for third parts 5 of different materials and shapes. Positioning systems, such as laser positioning, magnetic positioning, or mechanical positioning pins, can also be integrated into the first fixing assembly 1 and / or the second fixing assembly 2 to help quickly and accurately position the corresponding parts during installation. For example, positioning systems such as magnetic positioning can be set at the first connecting structure 12, the second connecting structure 24, and the third connecting structure 13 to improve the convenience of connection operations. The materials of the fixing device can be optimized to adapt to different usage 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 fixing device can adopt a modular design, meaning that the first fixing component 1 and the second fixing component 2 can be independently disassembled and replaced. This design allows the fixing device to be flexibly configured according to specific application scenarios, improving its maintainability and adaptability. The fixing device achieves modularity through the separate fixing design of the first fixing component 1 and the second fixing component 2. This design allows users to add or remove corresponding fixing components as needed to accommodate the fixing of parts of different numbers and sizes, improving the versatility and customizability of the fixing device.

[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 post 132. The main connection hole 131 penetrates the first fixing plate 11 and can be connected to the first part 3 and / or the second part 4. The positioning post 132 is disposed on the side of the first fixing plate 11 opposite to the second fixing assembly 2 and can be connected to the second part 4.

[0054] The main connecting hole 131 is one or more holes penetrating the first fixing plate 11, the diameter and position of which are designed according to specific application requirements. The main function of the main connecting hole 131 is to provide a direct connection point, allowing the second part 4, or possibly the first part 3, to establish a mechanical connection with the first fixing plate 11 via bolts, pins, or other fixing structures passing through this hole. 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, reducing swaying and displacement during movement, making it suitable for scenarios requiring large loads or high-precision positioning.

[0055] The positioning post 132 is a protruding structure located on the side of the first fixing plate 11 opposite to the second fixing component 2. Its shape can be cylindrical, but it can also be designed in other shapes as needed. The main function of the positioning post 132 is to provide a positioning reference for the second part 4, ensuring that the second part 4 can be more accurately aligned and positioned with the first fixing plate 11 during installation. Unlike the main connecting hole 131, the positioning post 132 is not used for direct mechanical connection, but rather serves as an auxiliary positioning element. This design is particularly suitable for applications requiring rapid installation and disassembly, and for situations where high accuracy in part positioning is required.

[0056] With this configuration, in this embodiment, whether through direct connection via the main connecting hole 131 or auxiliary positioning via the positioning post 132, the third connecting structure 13 ensures a stable connection between the second part 4 and the first fixing plate 11. In particular, the through-hole design of the main connecting hole 131 provides an additional fixing point, allowing it to withstand greater torque and load, thus improving the strength and stability of the fixing structure. The third connecting structure 13 can connect not only the second part 4 but also the first part 3. The fixing device has multi-part compatibility; one fixing device can simultaneously fix multiple parts, reducing the number of supports during assembly, simplifying the assembly process, and improving production efficiency.

[0057] The presence of the positioning post 132 provides a precise positioning reference for the second part 4, ensuring the accuracy of the part's installation position. This is particularly important for applications requiring high-precision positioning, such as the assembly of precision instruments or mechanical equipment. Since the third connecting structure 13 includes various forms of the main connecting hole 131 and the positioning post 132, it provides greater flexibility and adaptability for the use of the fixing device. Different application scenarios can select the appropriate connection method according to actual needs, enabling the fixing device to adapt to more diverse part fixing requirements.

[0058] Optionally, the main connecting hole 131 can be designed with different sizes or shapes according to the different fixing requirements of the first part 3 or the second part 4. For example, it can be a tapered hole, an elliptical hole, or multiple standard-sized round holes to accommodate fixing structures of different diameters or connectors of special shapes, thereby improving the compatibility and flexibility of the connection. The positioning post 132 can be designed with an adjustable height or position, such as using a threaded post or a telescopic post, to accommodate the second part 4 of different thicknesses or positions, allowing the user to adjust the positioning post 132 according to actual needs, ensuring the accurate installation and fixing of the second part 4.

[0059] The positioning post 132 can be designed as a detachable and replaceable component, allowing users to select the appropriate positioning post 132 for installation based on the specific shape and size of the second part 4. This modular design improves the adaptability and ease of maintenance of the fixing device. In addition to a cylindrical shape, the cross-sectional profile of the positioning post 132 can also be designed as a square, triangular, or other shape to match specific grooves or holes on the second part 4, providing a more precise positioning effect.

[0060] A reinforcing structure, such as annular reinforcing ribs or mesh reinforcing beams, can be designed around the main connecting hole 131 to improve the structural strength of the first fixing plate 11 in the hole area and prevent the material around the hole from deforming or cracking under heavy loads. For the second part 4 made of metal, the positioning post 132 can be designed to be made of a magnetic material to fix the second part 4 by magnetic attraction, providing initial positioning, and then finally fixing it by 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 connecting structure 13. The second fixing plate 21 includes a first sub-plate 211 and a second sub-plate 212, which are respectively disposed on both sides of the main connecting hole 131. At least two second support members 22 may be provided, and at least two second support members 22 are respectively disposed 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 partition plate 211 and the second partition plate 212 is to better accommodate the main connecting hole 131 and reduce interference from the second fixing plate 21 when the first part 3 and the third part 5 are fixed. The arrangement of the two partition plates allows the first part 3 or other connecting parts to approach the main connecting hole 131 from both sides or above, making the fixing more flexible and efficient. To ensure the stability and strength of the structure, at least two second support members 22 should be respectively set between the first partition plate 211 and the first fixing plate 11 and between the second partition 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 a single support point may bring by distributing 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 and second sub-plates 211 and 212. It maintains good mechanical performance 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 utilization of the main connecting hole 131, facilitate the installation of the first part 3. The first part 3 can approach the main connecting hole 131 from both sides or above without being obstructed by the second fixing plate 21, greatly simplifying the assembly process and improving assembly efficiency. The design of the first and second sub-plates 211 and 212 allows for more fixing points on the second fixing plate 21, i.e., the second connecting structure 24, and more parts, such as the third part 5, can be fixed to the second fixing plate 21, improving the versatility of the fixing device and the part fixing capability. By setting a first partition plate 211 and a second partition plate 212 on both sides of the main connecting hole 131, and setting a second support member 22 between these partition plates and the first fixing plate 11, the fixing device achieves 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, enabling the fixing device to perform complex fixing tasks in a limited space.

[0064] Optionally, the shape and size of the first partition plate 211 and the second partition plate 212 can be optimized according to the size and position of the main connecting hole 131. For example, the first partition plate 211 and the second partition plate 212 can be designed with arc-shaped edges or recessed bottoms 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 with a material with a certain degree of elasticity, such as spring steel or rubber. This elastic support can absorb some vibration and impact, improve the seismic performance of the fixing device, and is especially suitable for applications that require stability in dynamic environments.

[0065] To improve the mechanical strength of the second fixing plate 21, reinforcing ribs or support beams can be added to the first sub-plate 211 and the second sub-plate 212, especially around the second connecting structure 24, to prevent deformation of the area around the second connecting structure 24 due to stress. To prevent the third part 5 from sliding on the second fixing plate 21, anti-slip textures or coatings can 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, ensuring the stable fixing of the third part 5.

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

[0067] The arrangement direction of the first partition plate 211 and the second partition plate 212 refers to the spatial arrangement direction of the first partition plate 211 and the second partition plate 212, which can be horizontal or vertical, depending on the design of the fixing device and the application scenario.

[0068] The extension length refers to the longitudinal dimension of the first partition plate 211 and the second partition plate 212 in the layout direction, that is, the distance from the end that contacts the second support member 22 to the other end. Taking into account the length difference between the first partition plate 211 and the second partition plate 212, the size of the first partition plate 211 and the second partition plate 212 is limited.

[0069] With this configuration, when the extension length of the first plate 211 is greater than that of the second plate 212, the first plate 211 provides a larger support area on one side of the fixing device. This helps to enhance the structural stability of that side, especially when subjected to asymmetrical loads or lateral forces, and better maintains the balance of the fixing device. The longer first plate 211 can provide more fixing points, such as the location of the second connecting structure 24, which allows the fixing device to fix larger parts or multiple parts, enhancing the versatility and practicality of the fixing device. Different extension lengths allow the fixing device to adapt to parts of different sizes, especially for parts with different length requirements in the layout direction, providing a more flexible installation and fixing scheme. By adjusting the extension lengths of the first plate 211 and the second plate 212, the space occupation of the fixing device can be minimized while ensuring the fixing effect, especially in space-constrained application environments. In some application scenarios, when the fixing device needs to accurately position a third part 5 of different lengths, the difference in the extension lengths of the first plate 211 and the second plate 212 can serve as a positioning reference, ensuring accurate alignment between parts during installation.

[0070] Optionally, the first partition plate 211 and the second partition plate 212 can be designed as telescopic structures. For example, they can be adjusted via slide rails, telescopic rods, or threads. Users can adjust the extension length of the first partition plate 211 and the second partition plate 212 as needed to accommodate parts of different sizes, providing more flexible fixing options. In some cases, the extension length of the first partition plate 211 can be designed as stepped, meaning its length varies at different positions in the layout direction, forming multiple support planes. This can provide support points for parts of different heights, enhancing the load-bearing capacity and structural stability of the fixing device.

[0071] The extension lengths of the first plate 211 and the second plate 212 can be adjusted proportionally according to the expected load distribution. For example, on the side with a heavier expected load, the first plate 211 can be designed to be longer to provide a larger support area, while on the side with a lighter load, the length of the second plate 212 can be relatively reduced to save materials and space. Where it is not necessary to fix large parts, the first plate 211 and the second plate 212 can be designed as foldable structures, connected by hinges or folding rods, allowing them to be folded up, reducing space occupation and facilitating the storage and transportation of the fixing device.

[0072] like Figures 1 to 4 As shown, in some embodiments, a first support member 14 is provided at the bottom of the first fixing plate 11, and a first connecting structure 12 and a third connecting structure 13 are respectively provided on both sides of the first support member 14. The plate segment of the second fixing component 2 of the first fixing plate 11 and the first support member 14 surround 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 located at the bottom of the first fixing plate 11 and supports the entire fixing device, ensuring its stability during use. Multiple first support members 14 can be distributed at the bottom of the first fixing plate 11 according to load and stability requirements, and are typically columnar or plate-shaped structures. The fixing groove 15 is the space enclosed by the plate segment of the first fixing plate 11 where the second fixing component 2 is located and the first support member 14, used to accommodate and fix the second part 4. The design of the fixing groove 15 can accommodate second parts 4 of different shapes and sizes, providing a stable fixing effect.

[0074] This configuration enhances the bottom support of the first supporting member 14, improving the overall stability and load-bearing capacity of the fixing device, especially maintaining good structural performance under heavy loads. The first connecting structure 12 and the third connecting structure 13 are used to fix different types of parts, providing diverse fixing methods to adapt to the fixing needs of different parts, thus improving the versatility and flexibility of the fixing device. The design of the fixing groove 15 not only accommodates the second part 4 but also, through its specific structure, such as its cooperation with the third connecting structure 13, achieves precise positioning and stable fixing of the second part 4, reducing positional displacement and instability during the fixing process. By arranging the first connecting structure 12 and the third connecting structure 13 on both sides of the first supporting member 14 and forming the fixing groove 15, the fixing device can utilize limited space more efficiently, reducing its volume and increasing its application potential in confined spaces. The combination of the first fixing plate 11, the first connecting structure 12, the third connecting structure 13, and the fixing groove 15 allows the fixing device to fix multiple parts simultaneously, improving its practicality in complex assembly environments.

[0075] Optionally, the first support member 14 can be designed to be height-adjustable, for example, through threaded adjustment or a 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 consist of multiple independent support points to distribute the load and enhance the overall structural stability. These support points can be detachable for flexible adjustment according to the usage environment and load size. Integrating position sensors, pressure sensors, or vibration sensors on the first fixing plate 11 or the first support member 14 can monitor the fixing status of the second part 4 and the working conditions of the fixing device, helping to adjust the fixing strategy in real time or provide early warning of potential problems.

[0076] Reinforcing ribs or support beams can be added around the fixing groove 15 to improve its load-bearing capacity and structural strength. This reinforced design is 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. This design significantly improves assembly accuracy and efficiency, especially in applications requiring the alignment of multiple parts. The first fixing plate 11 can be designed as a modular structure, expanding or reducing the size of the fixing groove 15 by adding or removing plate segments to accommodate second parts 4 of different sizes, enhancing the flexibility and versatility of the fixing device.

[0077] like Figures 2 to 4 As shown, in some embodiments, there are multiple positioning posts 132, which are arranged within the fixing groove 15 and spaced apart along the extension direction of the first support member 14. This arrangement, by providing multiple positioning posts 132 within the fixing groove 15, allows for more precise positioning of the second part 4 during fixing, avoiding assembly errors caused by the offset of the second part 4 and improving the overall assembly accuracy. The spaced distribution of the multiple positioning posts 132 not only provides multiple positioning points but also strengthens the structure, especially under heavy loads, effectively dispersing stress, reducing deformation of the fixing groove 15, and enhancing the structural stability of the fixing device. The number and distribution of the positioning posts 132 can be adjusted according to the different sizes and shapes of the second part 4. This design flexibility allows the fixing device to adapt to a wider range of part fixing needs, improving its applicability in different application scenarios. The design of multiple positioning posts 132 simplifies the positioning process of the second part 4, eliminating the need for complex adjustment steps. Simply place the second part 4 within the fixing groove 15, and the positioning posts 132 will automatically complete the positioning, improving assembly efficiency. The uniform distribution of the positioning posts 132 reduces the risk of wear and damage to individual positioning posts 132, extends the service life of the fixing device, and thus reduces the cost of long-term maintenance and replacement.

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

[0079] The first reinforcing plate 16 is disposed between the first fixing plate 11 and the first support member 14 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 stress or vibration conditions. Multiple first reinforcing plates 16 can be provided, spaced apart along the extension direction of the first support member 14; for example, multiple first reinforcing plates 16 can be evenly spaced. The second reinforcing plate 25 can be disposed 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, to strengthen the structure and ensure the stability and reliability of the second fixing assembly 2 under load.

[0080] This configuration significantly enhances the structural strength of the fixing device by adding the first reinforcing plate 16 and the second reinforcing plate 25, enabling it to withstand greater loads and improving 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, reducing the displacement of corresponding parts or fixing failures caused by vibration, thus improving the accuracy and reliability of the fixing device. The design of the first reinforcing plate 16 and the second reinforcing plate 25 reduces the material thickness requirements for the first fixing plate 11, the first support member 14, the second fixing plate 21, and the second support member 22. Strength requirements are met through structural optimization, saving materials and reducing production costs. Furthermore, by adjusting the thickness, material, or layout of the first reinforcing plate 16 and the second reinforcing plate 25, the rigidity and stability of the first fixing component 1 and the second fixing component 2 can be further finely adjusted to adapt to the specific needs of different application scenarios. In high-temperature or large-temperature-varying working environments, the first reinforcing plate 16 and the second reinforcing plate 25 can alleviate the impact 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 with adjustable thickness or position. For example, the first fixing plate 11 and the second support member 22 can be detachably connected to the first reinforcing plate 16 by bolts or snap-fits. The first fixing plate 11 and the first support member 14 can be provided with multiple connection positions for connecting the first reinforcing plate 16. Similarly, the second fixing plate 21 and the second support member 22 can be detachably connected to the second reinforcing plate 25 by bolts or snap-fits. The second fixing plate 21 and the second support member 22 can be provided with multiple connection positions for connecting the second reinforcing plate 25, allowing the user to 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 first reinforcing plate 16 and the second reinforcing plate 25 can be made of high-strength composite materials, such as carbon fiber or glass fiber reinforced plastic, to significantly improve tensile strength and bending stiffness while maintaining lightweight, making them suitable for environments requiring high loads and low 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 fixed plate 11 to the connection position between the first fixed plate 11 and the first support member 14, thereby improving structural strength while reducing 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 between the first sub-plate 211 and 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 between the second sub-plate 212 and the second connecting member. This not only improves structural strength but also forms an arched clearance structure below the first sub-plate 211 and the second sub-plate 212, allowing for clearance during 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 connecting structure 12 includes a plurality of first auxiliary connecting holes 121, which are spaced apart on the first fixing plate 11; and / or, the second connecting structure 24 includes a plurality of second auxiliary connecting holes 241, which are spaced apart on the second fixing plate 21. The distance between two adjacent first auxiliary connecting holes 121 is equal to or greater than the distance between two adjacent second auxiliary connecting holes 241.

[0084] The first auxiliary connecting hole 121 is a hole on the first fixing plate 11, used for passing bolts, pins, or other connectors to fix the first fixing plate 11 to an external structure or the first part 3. The spaced arrangement of multiple first auxiliary connecting holes 121 provides multiple connection points, enhancing the reliability and stability of the connection. The second auxiliary connecting hole 241 is a hole on the second fixing plate 21, used for connection to an external structure or the third part 5. Similar to the first auxiliary connecting hole 121, the distributed design of multiple second auxiliary connecting holes 241 provides multiple connection points, ensuring a secure connection of the second fixing plate 21.

[0085] This configuration, by providing multiple spaced-apart first auxiliary connecting holes 121 and second auxiliary connecting holes 241 on the first fixing plate 11 and the second fixing plate 21, provides multiple fixing points, significantly enhancing the stability and reliability of the connection between the fixing device and the external structure or corresponding parts. The multiple configurations of the two types of auxiliary connecting holes allow users to select appropriate connection points according to actual needs, improving the applicability and flexibility of the fixing device and adapting to various connection requirements and environments. The spacing between two adjacent first auxiliary connecting holes 121 is equal to or greater than the spacing between two adjacent second auxiliary connecting holes 241. This 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 in applications requiring high stability by increasing the hole spacing. The design of multiple auxiliary connecting holes makes it easier to replace or adjust the corresponding connection positions when the fixing device needs maintenance or adjustment, reducing maintenance costs and downtime. By increasing the connection points, the load on individual connecting parts can be distributed, thereby improving the load-bearing capacity and durability of the overall connection system and reducing the risk of failure due to damage to connecting parts.

[0086] In this embodiment, to accommodate different types of connectors, the shape and size of the first auxiliary connecting hole 121 and the second auxiliary connecting hole 241 can be designed to be adjustable, such as elliptical, rectangular, or threaded holes, to meet the needs of different connectors such as bolts, pins, and rivets. Additionally, adding shock-absorbing materials or designing damping structures, such as rubber pads or bellows, around the holes can absorb and disperse external impacts, protecting the fixing device and connectors from damage.

[0087] like Figures 1 to 3 As shown, in some embodiments, there are multiple second fixing components 2, which are spaced apart 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] The term "multiple second fixing components 2" refers to the fact that the number of second fixing components 2 is not limited to one; there can be multiple components to accommodate the fixing needs of different numbers or sizes of parts, thereby improving the flexibility and application range of the fixing device. Optionally, the multiple second fixing components 2 are spaced apart on the first fixing plate 11, meaning that the distribution of the multiple second fixing components 2 on the first fixing plate 11 is spaced apart rather than continuous. This layout ensures that each second fixing component 2 has sufficient space, avoids mutual interference, and also facilitates the positioning and fixing of parts.

[0089] Optionally, the stacking of multiple second fixing components 2 in the vertical direction of the first fixing plate 11 means that the second fixing components 2 can be stacked in the vertical direction of the first fixing plate 11. This means that the second fixing components 2 can be set at different heights of the first fixing plate 11 to meet the fixing requirements of parts with height differences.

[0090] This embodiment, by setting multiple second fixing components 2, can simultaneously fix multiple parts, improving the fixing capability of the fixing device and making it suitable for application scenarios requiring the fixing of multiple parts or components. The spaced arrangement and stacked arrangement of the second fixing components 2 allow the fixing device to adapt to parts of different sizes and heights, improving the device's flexibility and versatility. Multiple second fixing components 2 can distribute the load when fixing parts, avoiding excessive force at a single point and improving the stability and safety of the fixing device. The spaced arrangement of the second fixing components 2 on the first fixing plate 11 and the stacked arrangement of the second fixing components 2 in the vertical direction can make reasonable use of space, achieving effective part fixing even in limited spaces. Through the preset spacing and stacked layout, the assembly of the second fixing components 2 can be faster and more accurate, reducing adjustment and positioning time during assembly. The flexible layout of the second fixing components 2 allows the fixing device to adapt to more complex assembly environments, such as fixing multi-layer structures or fixing in specific space constraints. The setting of multiple second fixing components 2, by increasing connection points and distributing loads, can enhance the overall structural strength of the fixing device and improve its reliability under high load or vibration environments.

[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 detachable connections such as bolts or sliding connections driven by cylinders or hydraulic cylinders. Users 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 in the figure, the X direction is the first direction, the Y direction is the third direction, and the Z direction is the second direction.

[0093] An embodiment of the second aspect of the present invention provides a vehicle including a first part 3, a second part 4, a third part 5, and a fixing device as described in any of the above embodiments. The first part 3 and the second part 4 are disposed on a first fixing assembly 1, and the third part 5 is disposed on a second fixing assembly 2. The first part 3 and the third part 5 can extend along a first direction, and the first part 3 and the third part 5 have a height difference in a second direction. The second part 4 can extend along a third direction. The first direction, the second direction, and the third direction intersect each other, for example, the first direction, the second direction, and the third direction can be perpendicular to each other.

[0094] The first part 3 is a component of the vehicle and extends along a first direction, forming a specific height difference with other parts. The first direction is typically the vehicle's transverse or longitudinal direction, depending on the part's layout. The first part 3 can be inserted through the mounting channel 23 and can be fixed to the first mounting plate 11 via the first connecting structure 12 and / or the third connecting structure 13. The second part 4 is another component of the vehicle and extends along a third direction, intersecting with both the first and second directions, so that the layout of the second part 4 forms a three-dimensional interlacing relationship with the first part 3 and the third part 5 to accommodate complex spatial requirements within the vehicle. The second part 4 can be fixed to the first mounting plate 11 via the third connecting structure 13. The third part 5 is yet another component of the vehicle, having a height difference from the first part 3 in the second direction. The first part 3 and the third part 5 are positioned differently in the vehicle's vertical direction, requiring a fixing device to ensure a stable connection between them. The third part 5 can be fixed to the second mounting plate 21 via the second connecting structure 24. The fixing device is used to form a stable and adjustable connection between different parts, particularly suitable for situations where there are structural avoidances and height differences between parts.

[0095] This configuration, using a fixing device within the vehicle, allows for a three-dimensional spatial arrangement of the first part 3, the second part 4, and the third part 5. Even with complex spatial relationships between parts, it ensures effective fixation, improving the flexibility and space utilization efficiency of vehicle design. The fixing device can accommodate height differences between the first part 3 and the third part 5 in a second direction, such as the vertical direction, facilitating stable connections between parts of different heights. The fixing device supports parts extending in different directions—the first, second, and third directions. This directional fixing capability enables the fixing device to withstand various dynamic loads during vehicle operation, improving the reliability and stability of connections between parts. The use of the fixing device strengthens the connections between internal vehicle parts, thereby increasing the strength and rigidity of the overall vehicle structure and helping to maintain structural integrity under complex driving conditions such as bumpy roads and high-speed driving. The fixing device can serve as a layout tool, helping to optimize the arrangement of internal vehicle parts, enabling efficient and stable connections even in limited spaces, contributing to improved vehicle performance and reduced energy consumption. The precise positioning capability and highly compatible fixing methods of the fixing device improve the accuracy of vehicle assembly, ensuring correct alignment between parts, thereby reducing assembly errors and enhancing the overall quality of the vehicle.

[0096] Since the vehicle of the present invention includes the aforementioned fixing device, it has all the advantages and beneficial effects of the above embodiments, which will not be repeated here.

[0097] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the implementation of the present invention. Those skilled in the art will be able to make various obvious changes, readjustments, and substitutions without departing from the scope of protection of the present invention. It is neither necessary nor possible to exhaustively describe all embodiments here.
