Description

Technical Field

[0001] This utility model relates to the field of agricultural machinery technology, and in particular to a rearview mirror assembly mounting bracket structure and agricultural machinery. Background Technology

[0002] Rearview mirrors are the primary visual aids for drivers to observe their surroundings, crop harvesting, and ensure safe driving operations. They are typically positioned on the outermost edge of the machine to provide a reliable and clear rear view, enabling efficient operation. In existing rearview mirror assembly structures, the width of the cab is often limited by the width ratio of the grain bin and protective covers, requiring long cantilever supports to ensure a sufficiently large field of view. However, as the operating speeds of agricultural machinery (such as harvesters) increase, the vibrations and shaking of the cab also increase. The continuous impact of high-frequency, heavy loads on the cab causes constant shaking and vibration, which, combined with the long cantilever rearview mirror supports, results in severe rearview mirror vibration, affecting visibility and even causing dizziness for the driver and passengers. Utility Model Content

[0003] This utility model provides a rearview mirror assembly mounting bracket structure and agricultural machinery, which can improve the technical problem of poor installation stability of rearview mirror assemblies in the prior art.

[0004] The technical solution of this utility model to solve the above-mentioned technical problems is as follows:

[0005] This utility model provides a rearview mirror assembly mounting bracket structure, including a mounting bracket assembly, the mounting bracket assembly comprising:

[0006] The transition mounting plate has multiple fixing holes through one end, each of which is used for bolts threaded to the top cover to pass through.

[0007] The first reinforcing bracket is fixedly connected to one side of the transition mounting plate on one side;

[0008] The second reinforcing bracket has one end fixedly connected to one side of the transition mounting plate and is arranged opposite to the first reinforcing bracket;

[0010] The transition mounting plate, the first reinforcing bracket, the second reinforcing bracket, and the reinforcing plate together form a frame structure, and the ends are used to extend out of the top cover and to fix the rearview mirror assembly.

[0011] The beneficial effects of this utility model are: the transition mounting plate, the first reinforcing bracket, the second reinforcing bracket, and the reinforcing plate together form a frame structure, which ensures the rigidity of the entire mounting bracket assembly, giving the mounting bracket assembly a multi-directional anti-torsion effect, and using multiple bolts passing through the fixing holes to fix it to the top cover, forming a multi-point fixing effect, thus improving the technical problem of poor installation stability of the rearview mirror assembly in the prior art.

[0012] Based on the above technical solution, the present invention can be further improved as follows.

[0013] Furthermore, the mounting bracket assembly also includes a third reinforcing bracket located on the same plane as the reinforcing plate. The reinforcing plate and the third reinforcing bracket are located at both ends of the transition mounting plate, and the two sides of the third reinforcing bracket are fixedly connected to the first reinforcing bracket and the second reinforcing bracket, respectively.

[0014] Furthermore, the third reinforcing bracket, together with the first and second reinforcing brackets, forms a clearance groove, which opens in a direction away from the transition mounting plate.

[0015] Furthermore, both the first and second reinforcing brackets have transverse insertion holes on their side walls, and the third reinforcing bracket is fixedly connected with multiple transverse insertion plates, each of which is adapted to and inserted into the respective transverse insertion hole.

[0016] Furthermore, the mounting bracket assembly also includes a sealing plate, which is fixedly connected to the transition mounting plate, the first reinforcing bracket, and the second reinforcing bracket, and one side of the sealing plate is used to abut against the inner wall of the top cover.

[0017] Furthermore, the mounting bracket assembly also includes a wire harness mounting plate fixedly connected to the second reinforcing bracket, the wire harness mounting plate having a through wire harness hole.

[0018] Furthermore, the mounting bracket assembly also includes a threaded post detachably connected to one end of the first reinforcing bracket, the threaded post being used to insert into the top cover.

[0019] Furthermore, one end of the first reinforcing bracket is fixedly connected to an inclined section, which extends inclinedly to the middle position of the transition mounting plate.

[0020] Furthermore, the first reinforcing bracket has multiple vertical insertion holes, and both the first and second reinforcing brackets are fixedly connected to vertical insertion plates, each of which is adapted to and inserted into the respective vertical insertion hole.

[0021] This utility model also provides an agricultural machinery, including the aforementioned rearview mirror assembly mounting bracket structure. Attached Figure Description

[0032] The principles and features of this utility model are described below with reference to the accompanying drawings. The examples given are only for explaining this utility model and are not intended to limit the scope of this utility model.

[0033] In existing technologies, to accommodate the width of the rear grain bin, protective cover, etc., the rearview mirror assembly is designed as a relatively long cantilever structure to ensure the rearward visibility of the driver and passengers. The existing rearview mirror assembly mounting structures mainly fall into the following two categories:

[0034] I. For example Figure 7The rearview mirror assembly 1 is fixed to the middle section of the A-pillar of the cab 2 via the mounting bracket assembly 4. The mounting bracket assembly 4 is a welded structure of bent round tube. This fixed bracket structure lacks three-dimensional support, has poor torsional resistance, and does not meet the usage requirements.

[0035] II. Figure 8 The rearview mirror assembly 1 is fixed to the upper section of the A-pillar of the cab 2 via the rearview mirror mounting bracket assembly 4. The mounting bracket assembly 4 is a bent U-shaped bracket structure. This type of fixed bracket structure has poor torsional resistance and does not meet the usage requirements.

[0036] In summary, the rearview mirrors with the existing mounting bracket assembly and long cantilever mounting structure will vibrate and shake synchronously with the continuous shaking and vibration of the cab. This cantilever mounting structure cannot guarantee the installation stability requirements of the rearview mirrors.

[0037] To address the aforementioned issues, this utility model provides a rearview mirror assembly mounting bracket structure, as detailed below.

[0038] Example 1

[0039] like Figures 1-6 A rearview mirror assembly mounting bracket structure includes a mounting bracket assembly 4, the mounting bracket assembly 4 comprising:

[0040] The transition mounting plate 41 has multiple fixing holes 5 through one end, and each fixing hole 5 is used for bolts threaded to the top cover 3 to pass through.

[0041] The first reinforcing bracket 42 is fixedly connected to one side of the transition mounting plate 41 on one side;

[0042] The second reinforcing bracket 43 has one end fixedly connected to one side of the transition mounting plate 41 and is arranged opposite to the first reinforcing bracket 42.

[0043] The reinforcing plate 44 is fixedly connected to the first reinforcing bracket 42 and the second reinforcing bracket 43 on both sides respectively.

[0044] The transition mounting plate 41, the first reinforcing bracket 42, the second reinforcing bracket 43, and the reinforcing plate 44 together form a frame structure, with the ends extending out of the top cover 3 and used to fix and connect the rearview mirror assembly 1.

[0045] The beneficial effects of this embodiment are: the transition mounting plate 41, the first reinforcing bracket 42, the second reinforcing bracket 43 and the reinforcing plate 44 together form a frame structure, which ensures the rigidity of the entire mounting bracket assembly 4, so that the mounting bracket assembly 4 has a multi-directional anti-torsion effect, and is fixed to the top cover 3 by multiple bolts passing through the fixing holes 5, forming a multi-point fixing effect, which improves the technical problem of poor installation stability of the rearview mirror assembly 1 in the prior art.

[0046] In addition, the existing cab 2 and roof 3 are usually closed cavity structures that are fixed by bolts. The roof 3 is made of non-metallic material, and each fixing point is a pre-embedded nut, which has low strength. Moreover, there are no rigid connecting parts between each fixing point, and the fixing points are relatively independent. The overall structure has poor torsional resistance, and the roof 3 has poor installation stability, which does not meet the usage requirements.

[0047] In this application, the mounting bracket assembly 4, which has an overall frame structure, is fixed to the top cover 3 using bolts passing through each fixing hole 5. This mounting bracket assembly 4 forms a "reinforcing rib" effect, improving the torsional resistance of the overall structure of the top cover 3. Compared to the prior art method of fixing the mounting bracket assembly 4 to the A-pillar of the cab 2, the mounting bracket assembly 4, with its overall frame structure fixed to the top cover 3, increases the number of fixing points, thus improving stability.

[0048] Based on the above embodiments, the length ratio of one end of the mounting bracket assembly 4 fixed to the top cover 3 to the other end extending out of the top cover 3 is not less than 8:1, so as to further improve the installation stability of the mounting bracket assembly 4 as the mounting base of the rearview mirror assembly 1.

[0049] Based on the above embodiments, slots 9 are provided on the other side of the first reinforcing bracket 42 and the second reinforcing bracket 43, and the reinforcing plate 44 is formed with inserts 91 that fit and insert into the slots 9, so as to form a positioning installation through the slots 9 and realize quick assembly and disassembly of the reinforcing plate 44. After installation, the reinforcing plate 44, the first reinforcing bracket 42, and the second reinforcing bracket 43 are welded to ensure structural stability.

[0050] Example 2

[0051] like Figures 2-6 Based on embodiment 1, the mounting bracket assembly 4 further includes a third reinforcing bracket 45 located on the same plane as the reinforcing plate 44. The reinforcing plate 44 and the third reinforcing bracket 45 are located at both ends of the transition mounting plate 41, and the two sides of the third reinforcing bracket 45 are fixedly connected to the first reinforcing bracket 42 and the second reinforcing bracket 43, respectively.

[0052] The beneficial effect of adopting the preferred solution in the above embodiments is that the reinforcing plate 44 and the third reinforcing bracket 45 located on the same plane make the transition mounting plate 41, the first reinforcing bracket 42 and the second reinforcing bracket 43 form a complete frame structure. The transition mounting plate 41, the first reinforcing bracket 42, the second reinforcing bracket 43 and the third reinforcing bracket 45 form a frame structure located inside the top cover 3, which can improve the structural stability of the entire mounting bracket assembly 4. The transition mounting plate 41, the first reinforcing bracket 42, the second reinforcing bracket 43 and the reinforcing plate 44 form a frame structure extending outside the top cover 3 and serve as the mounting base for the rearview mirror assembly 1 to ensure the installation stability of the rearview mirror assembly 1.

[0053] Example 3

[0054] like Figure 3 and Figure 4 Based on embodiments 1 and 2, the third reinforcing bracket 45, together with the first reinforcing bracket 42 and the second reinforcing bracket 43, forms a clearance groove 6, which opens in the direction away from the transition mounting plate 41.

[0055] The beneficial effect of adopting the preferred solution in the above embodiments is that, while forming a stable frame structure within the top cover 3 through the transition mounting plate 41, the first reinforcing bracket 42, the second reinforcing bracket 43 and the third reinforcing bracket 45, the clearance groove 6 is used to avoid structural features on the top cover 3.

[0056] Example 4

[0057] like Figure 5 and Figure 6 Based on embodiments 1-3, the side walls of the first reinforcing bracket 42 and the second reinforcing bracket 43 are provided with transverse insertion holes 7, and the third reinforcing bracket 45 is fixedly connected with multiple transverse insertion plates 71, each transverse insertion plate 71 being adapted to and inserted into each transverse insertion hole 7.

[0058] The beneficial effect of adopting the preferred solution in the above embodiments is that the third reinforcing bracket 45 is quickly positioned and assembled by inserting the transverse insert plate 71 into the corresponding transverse insert hole 7. After assembly and positioning, welding is performed, which helps to increase the welding area or weld length between the two, thereby improving the connection strength.

[0059] Example 5

[0060] like Figures 2-6 Based on embodiments 1-4, the mounting bracket assembly 4 further includes a sealing plate 46, which is fixedly connected to the transition mounting plate 41, the first reinforcing bracket 42 and the second reinforcing bracket 43, and one side of the sealing plate 46 is used to abut against the inner wall of the top cover 3.

[0061] The beneficial effect of adopting the preferred solution in the above embodiments is that the sealing structure formed by the sealing plate 46 to form the top cover 3 for the through holes of the installation transition plate 41, the first reinforcing bracket 42, the second reinforcing bracket 43 and the reinforcing plate 44 reduces the possibility of external debris entering the top cover 3.

[0062] The sealing plate 46 has a stepped groove through which the transition mounting plate 41, the first reinforcing bracket 42, and the second reinforcing bracket 43 pass. The end of the transition mounting plate 41 extends into the large-diameter end of the stepped groove to form a stable installation. After passing through, the sealing plate 46, the transition mounting plate 41, the first reinforcing bracket 42, and the second reinforcing bracket 43 are welded together.

[0063] Example 6

[0064] like Figures 2-6 Based on embodiments 1-5, the mounting bracket assembly 4 further includes a wire harness mounting plate 47 fixedly connected to the second reinforcing bracket 43, and the wire harness mounting plate 47 has a through wire harness hole.

[0065] The advantage of adopting the preferred solution in the above embodiments is that the wire harness is installed through the wire harness mounting plate 47, thereby improving the functionality of the mounting bracket assembly 4.

[0066] Example 7

[0067] like Figures 2-6 Based on embodiments 1-6, the mounting bracket assembly 4 also includes a threaded post 48 detachably connected to one end of the first reinforcing bracket 42, the threaded post 48 being used to insert the top cover 3.

[0068] The advantage of the preferred solution in the above embodiments is that by using the threaded post 48 as the positioning and installation center, precise installation between the mounting bracket assembly 4 and the top cover 3 can be achieved.

[0069] Example 8

[0070] like Figures 2-6 Based on embodiments 1-7, one end of the first reinforcing bracket 42 is fixedly connected to an inclined section 421, which extends inclinedly to the middle of the transition mounting plate 41.

[0071] The beneficial effect of adopting the preferred solution in the above embodiments is that the support for the first reinforcing bracket 42 is formed by the inclined section 421, thereby improving the structural strength of the first reinforcing bracket 42.

[0072] Example 9

[0073] like Figure 5 and Figure 6 Based on embodiments 1-8, the first reinforcing bracket 42 has multiple vertical insertion holes 8, and both the first reinforcing bracket 42 and the second reinforcing bracket 43 are fixedly connected with vertical insertion plates 81, each vertical insertion plate 81 being adapted to and inserted into each vertical insertion hole 8.

[0074] The beneficial effect of adopting the preferred solution in the above embodiments is that the first reinforcing bracket 42 and the second reinforcing bracket 43 can be quickly positioned and assembled by inserting the vertical insert plate 81 into the corresponding vertical insert hole 8. After assembly and positioning, welding is performed, which helps to increase the welding area or weld length between the two, thereby improving the connection strength.
