Description

Technical Field

[0001] The present application belongs to the technical field of damping hinges, and specifically relates to a damping hinge and operating equipment. Background Art

[0002] Damping hinges are a common connection mechanism. When connecting long-arm structures, the damping force provided by existing damping hinges is usually insufficient to effectively maintain the stability of the long-arm structure, which can easily cause the long-arm structure to vibrate, causing adverse effects in some application scenarios. For example, in tractors, the rearview mirror is generally connected to the damping hinge on the side of the cab via a long arm. When the damping hinge cannot maintain the stability of the long arm, it will cause the rearview mirror to vibrate, affecting normal operation. Therefore, in order to improve the reliability of the damping hinge when connecting long-arm structures, it is necessary to optimize its design. Utility Model Content

[0007] a rotating mechanism, comprising a rotating shaft, wherein the rotating shaft is rotatably connected to the first base and fixedly connected to the second base, so that the second base can rotate relative to the first base; and

[0008] The damping mechanism includes a turntable and an elastic pressing structure. The turntable is fixed to the rotating shaft through a sleeve. The elastic pressing structure is arranged at intervals on the radial outside of the rotating shaft and is elastically pressed between the first seat and the disk surface of the turntable.

[0009] In some embodiments, the pre-tightening force of the elastic pressing structure elastically pressed between the first seat and the disk surface of the turntable is adjustable;

[0013] In some embodiments, the elastic crimping structure includes a mounting sleeve embedded in the first seat body, and the inner peripheral wall of the mounting sleeve forms a threaded connection with the outer peripheral wall of the mounting member, so that the preload force of the elastic member can be adjusted by rotating the mounting member to adjust the position in the mounting sleeve.

[0014] In some embodiments, a locating pin hole is provided on a peripheral wall of the mounting sleeve, and the elastic crimping structure includes an anti-slip pin passing through the first seat body and the locating pin hole.

[0015] In some embodiments, a shifting groove is formed on the surface of the turntable, and the elastic crimping structure includes a fixed end fixedly connected to the first seat body and a crimping end that can be inserted into or out of the shifting groove when the second seat body drives the turntable to rotate.

[0016] In some embodiments, there are multiple shift grooves, which are arranged in sequence along the circumference of the turntable. The crimping end of the elastic crimping structure can be engaged with the multiple shift grooves in sequence when the second seat drives the turntable to rotate.

[0017] In some embodiments, the crimping end is provided with a crimping spherical surface, and the shifting groove is provided with a groove wall spherical surface capable of engaging with the crimping spherical surface.

[0018] In some embodiments, the elastic pressing structures are provided in plurality and are arranged in pairs, and the turntable is pressed between two of the elastic pressing structures arranged in pairs.

[0019] In some embodiments, the damping hinge comprises:

[0020] a first limiting structure, connected to the second base and capable of abutting against the first base to limit a maximum rotation angle of the second base along a first rotation direction;

[0021] The second limiting structure is connected to the second base and can abut against the first base to limit the maximum rotation angle of the second base along a second rotation direction, and the second rotation direction is set opposite to the first rotation direction.

[0022] In some embodiments, the first limiting structure is provided with a first card slot, the second limiting structure is provided with a second card slot, the second seat is provided with a first card plate that is inserted into the first card slot and a second card plate that is inserted into the second card slot, and the peripheral wall of the turntable abuts against the first limiting structure and the second limiting structure toward the first card plate and the second card plate.

[0027] Through the above technical solution, the damping hinge of the present application utilizes an elastic pressing structure to press the surface of the turntable, which can generate friction at the contact position between the elastic pressing structure and the surface of the turntable. At the same time, since the elastic pressing structure is spaced apart on the radially outer side of the rotating shaft, compared with existing damping hinges of the same size, the damping hinge of the present application has a longer damping lever arm, thereby having a larger damping torque. In this way, even when the second base is connected to a long-arm structure, the second base is not easy to rotate relative to the first base, and the position of the long-arm structure connected to the second base can be effectively maintained stable, so that the long-arm structure is suspended. At this time, the damping hinge plays a role in limiting the long-arm structure, thereby improving reliability and broadening the applicable scenarios. For example, the damping hinge of the present application can be used to connect the rearview mirror assembly of operating equipment such as tractors, which can effectively reduce the risk of vibration of the rearview mirror assembly and avoid affecting normal operation.

[0054] The following describes the specific embodiments of the present application in detail with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only used to illustrate and explain the present application and are not intended to limit the present application.

[0055] Reference Figures 1 to 7 A first exemplary embodiment of the present application provides a damping hinge, comprising:

[0056] First seat body 1;

[0057] Second seat body 5;

[0058] The rotating mechanism 3 includes a rotating shaft 21, which is rotatably connected to the first base body 1 and is fixed to the second base body 5, so that the second base body 5 can rotate relative to the first base body 1; and

[0059] The damping mechanism 2 includes a turntable 11 and an elastic pressing structure. The turntable 11 is sleeved and fixed on the rotating shaft 21. The elastic pressing structure is spaced apart on the radial outside of the rotating shaft 21 and elastically pressed between the first base 1 and the disk surface of the turntable 11.

[0060] Through the above technical solution, the damping hinge of the present application utilizes the elastic pressing structure to press the disk surface of the turntable 11, which can form a friction force at the contact position between the elastic pressing structure and the disk surface of the turntable 11. At the same time, since the elastic pressing structure is arranged at intervals on the radial outside of the rotating shaft 21, the damping hinge of the present application has a longer damping force arm L (refer to FIG. Figure 2 ), thereby providing a greater damping torque. Thus, even when the second base body 5 is connected to a long arm structure, the second base body 5 is unlikely to rotate relative to the first base body 1, effectively maintaining the position of the long arm structure connected to the second base body 5, allowing the long arm structure to hover. In this case, the damping hinge acts as a limiter for the long arm structure, improving reliability and expanding its application scenarios. For example, the damping hinge of the present application can be used to connect the rearview mirror assembly of operating equipment such as tractors, effectively reducing the risk of rearview mirror assembly vibration and preventing it from affecting normal operation.

[0061] When the second base body 5 needs to be rotated, for example, when a long arm-like structure is connected to the second base body 5, a torque sufficient to overcome the damping torque and rotate the second base body 5 needs to be applied to the long arm-like structure. When the second base body 5 rotates relative to the first base body 1, the elastic pressing structure still maintains pressure on the surface of the rotating disk 11. At this time, the elastic pressing structure and the surface of the rotating disk 11 form sliding friction, which can slow down the rotation speed of the second base body 5 and prevent the long arm-like structure connected to the second base body 5 from rotating rapidly, thereby protecting the long arm-like structure. For example, when the position of the rearview mirror assembly needs to be adjusted, this can prevent the rearview mirror assembly from moving too quickly and causing an accidental collision.

[0062] In some embodiments, reference Figure 1 、 Figure 4 and Figure 7 A first chamber is provided in the first base body 1, and a second chamber is provided in the second base body 5. The turntable 11 can rotate in the first chamber and the second chamber. At this time, in order to realize the elastic pressing structure to press the disk surface of the turntable 11, the elastic pressing structure can also be built into the first base body 1, so that the damping hinge of the present application has a more compact structure, a smaller size, and a smooth and beautiful appearance, and can be used directly as an appearance part without a jacket.

[0063] Of course, in some other embodiments, the turntable 11 and the elastic pressing structure can also be arranged outside the first base body 1 and the second base body 5, and do not have to be built into the first base body 1 and the second base body 5. This application does not limit the specific setting method of the turntable 11 and the elastic pressing structure.

[0064] In some embodiments, reference Figure 4 The elastic crimping structure may include a mounting member 31 connected to the first base body 1, a crimping member 33 crimped to the disk surface of the turntable 11, and an elastic member 32 (for example, a rubber spring, a heavy metal spring, etc.) elastically crimped between the mounting member 31 and the crimping member 33.

[0065] When the first base 1 and the second base 5 are relatively fixed, the crimping member 33 is kept pressed against the surface of the turntable 11 by the elastic force of the elastic member 32. When the second base 5 drives the rotating shaft 21 to rotate, and the rotating shaft 21 drives the turntable 11 to rotate, the position of the crimping member 33 pressed against the surface of the turntable 11 changes. The changing trajectory of the crimping position of the crimping member 33 and the surface of the turntable 11 can be seen in FIG. Figure 5 The crimping position track i in .

[0066] In some embodiments, reference Figure 4 The elastic pressing structure may include a mounting sleeve 34 embedded in the first seat body 1, and the inner peripheral wall of the mounting sleeve 34 is threadedly connected to the outer peripheral wall of the mounting member 31 (see Figure 4The threaded engagement position between the mounting sleeve 34 and the mounting member 31 is defined as e). Thus, by rotating and adjusting the position of the mounting member 31 in the mounting sleeve 34, the compression of the elastic member 32 can be increased or decreased, thereby adjusting the preload force of the elastic member 32. This, in turn, adjusts the pressing force applied by the crimping member 33 on the surface of the turntable 11. The friction force at the contact point between the crimping member 33 and the surface of the turntable 11 can be adjusted accordingly, making the damping hinge adaptable to a wider range of usage scenarios.

[0067] In addition, through the arrangement of this embodiment, when assembling the damping hinge, after the mounting sleeve 34 is embedded in the first base body 1 and the turntable 11 is installed, it is only necessary to successively place the crimping piece 33 and the elastic piece 32 into the mounting sleeve 34, and finally place the mounting piece 31 into the mounting sleeve 34, and rotate and adjust the mounting piece 31 to a preset position in the mounting sleeve 34, so that the elastic piece 32 is pre-compressed and the crimping piece 33 is crimped onto the surface of the turntable 11, and the assembly of the mounting piece 31, the elastic piece 32 and the crimping piece 33 can be completed. The assembly method of this elastic crimping structure is convenient and quick, and does not require the aid of additional clamping auxiliary tooling. Therefore, compared with the existing damping hinge, it can greatly improve the assembly efficiency and save installation costs.

[0068] In some embodiments, reference Figure 4 The peripheral wall of the mounting sleeve 34 may be provided with a positioning pin hole, and the elastic crimping structure may include an anti-slip pin 35 that passes through the first base body 1 and the positioning pin hole. With this arrangement, after the mounting sleeve 34 is embedded in the first base body 1, the anti-slip pin 35 can be used to pass through the first base body 1 and the positioning pin hole, thereby strengthening the fixation of the mounting sleeve 34 and preventing the mounting sleeve 34 from falling out of the first base body 1. In particular, when the mounting member 31 is rotated to adjust the position of the mounting member 31 in the mounting sleeve 34, the mounting sleeve 34 can be effectively prevented from moving.

[0069] In some embodiments, reference Figure 5 The surface of the turntable 11 may be formed with a shifting groove h, and the elastic pressing structure may include a fixed end fixedly connected to the first base 1 and a pressing end capable of engaging with or disengaging from the shifting groove h during the process of the turntable 11 being rotated by the second base 5. For example, when the elastic pressing structure is provided with the aforementioned mounting member 31, elastic member 32, and pressing member 33, the fixed end of the elastic pressing structure is located on the mounting member 31, and the pressing end of the elastic pressing structure is located on the pressing member 33.

[0070] When the crimping end of the elastic crimping structure is stuck in the gear slot h, the damping torque of the damping hinge is further increased. If the second base body 5 is to rotate relative to the first base body 1, it is necessary to apply a greater thrust to the second base body 5 to make the crimping end of the elastic crimping structure disengage from the gear slot h. Therefore, when the crimping end of the elastic crimping structure is stuck in the gear slot h, the long arm-like structure connected to the second base body 5 can hover more stably. At this time, the gear slot h is equivalent to the hovering gear of the long arm-like structure.

[0071] In some embodiments, reference Figure 5 There can be multiple gear slots h, and the multiple gear slots h are arranged in sequence along the circumference of the turntable 11, and the multiple gear slots h are all located on the crimping position trajectory i. At this time, the crimping end of the elastic crimping structure can be sequentially engaged with the multiple gear slots h in the process of the second seat body 5 driving the turntable 11 to rotate, so that the hovering stability of the long arm structure can be improved at the positions of the multiple gear slots h. At this time, the multiple gear slots h serve as multiple hovering gears of the long arm structure.

[0072] In some embodiments, reference Figure 4 The crimping end of the elastic crimping structure can be provided with a crimping spherical surface. In this case, the shifting slot h is provided with a spherical surface on the slot wall that can engage with the crimping spherical surface. That is, the contact point between the crimping spherical surface of the elastic crimping structure and the spherical surface on the slot wall of the shifting slot h forms a spherical mating position g. By providing this spherical mating position g, the crimping end of the elastic crimping structure can be prevented from becoming stuck in the shifting slot h, thereby causing the rotational function of the damping hinge to fail, while increasing the damping torque of the damping hinge. In other words, the damping hinge can maintain its original basic function while increasing the damping torque.

[0073] The following summarizes some embodiments of adjusting the pressing force applied by the elastic pressing structure on the turntable 11:

[0074] For example, the elastic pressing structure can be configured to have an adjustable preload force. For example, in the embodiment described above, when the elastic pressing structure includes a mounting sleeve 34, a mounting member 31, an elastic member 32, and a pressing member 33, the position of the mounting member 31 within the mounting sleeve 34 can be adjusted by rotating the mounting member 31 to increase or decrease the compression of the elastic member 32, thereby adjusting the preload force of the elastic member 32 and thereby adjusting the pressing force applied by the pressing member 33 to the surface of the turntable 11.

[0075] Alternatively, the damping mechanism 2 may include multiple interchangeable elastic pressing structures with different preload forces. In this embodiment, when the pressing force exerted by the elastic pressing structure on the turntable 11 needs to be adjusted, a different elastic pressing structure is required. When using elastic pressing structures with different preload forces, the pressing forces exerted by the elastic pressing structure on the turntable 11 will also vary, thereby achieving the purpose of adjusting the pressing force.

[0076] Alternatively, the damping mechanism 2 may include a plurality of turntables 11 of different thicknesses that can be used interchangeably. In this embodiment, when it is necessary to adjust the pressing force applied by the elastic pressing structure on the turntable 11, a different turntable 11 needs to be replaced. When using turntables 11 with different thicknesses, the distance between the turntable 11 and the elastic pressing structure will also be different, so that the compression amount of the elastic pressing structure will also be different, and the pressing force applied to the turntable 11 will also be different. Therefore, this embodiment can also achieve the purpose of adjusting the pressing force. It should be noted that the thickness of the turntable 11 referred to here can be the thickness at a position on the turntable 11 where the shift groove h is not provided, or it can be the thickness at the shift groove h on the turntable 11, wherein the different thicknesses at the shift groove h are actually equivalent to the different depths of the shift groove h.

[0077] It can be seen that by configuring the above-listed embodiments, the pressing force applied by the elastic pressing structure to the turntable 11 can be adjusted, thereby making the damping hinge of the present application applicable to a wider range of scenarios. It should be noted that the above-listed embodiments can be configured individually or in combination in the damping hinge, and this application does not limit this.

[0078] In some embodiments, the turntable 11 and the rotating shaft 21 are fixed to each other only along the circumferential direction, and can move relative to each other along the axial direction. Figures 4 to 6 The peripheral wall of the rotating shaft 21 may be provided with a key mounting groove m, in which an anti-rotation key 12 is installed. At the same time, a key matching groove j is provided on the turntable 11. When the turntable 11 is inserted into and fixed on the rotating shaft 21, the anti-rotation key 12 is inserted into the key matching groove j, thereby realizing that the turntable 11 and the rotating shaft 21 are fixed to each other in the circumferential direction and can move relative to each other along the axial direction.

[0079] In the case that the turntable 11 and the rotating shaft 21 are relatively movable along the axial direction, when the clamping force applied by the elastic crimping structure on the turntable 11 is adjusted, since the turntable 11 is not axially fixed, the turntable 11 can adaptively adjust its own position along the axial direction to avoid the turntable 11 and the rotating shaft 21 from being subjected to axial pressure from each other, thereby avoiding the generation of internal stress, which is beneficial to extending the service life and can reduce the strength requirements of the rotating shaft 21 and the turntable 11.

[0080] In some embodiments, reference Figure 4 The elastic pressing structure can be provided with multiple ones and arranged in pairs. At this time, the turntable 11 is pressed between the two elastic pressing structures arranged in pairs. The structure is symmetrical, and the force on both sides of the turntable 11 is uniform, which can prevent the turntable 11 from being deflected and exerting pressure on the rotating shaft 21, and prevent the turntable 11 and the rotating shaft 21 from being subjected to axial pressure from each other, thereby avoiding internal stress, which is beneficial to extending the service life and can reduce the strength requirements of parts such as the rotating shaft 21, the turntable 11 and the elastic pressing structure.

[0081] In some embodiments, reference Figure 2 and Figure 3 The damping hinge may include a limiting structure 4, which may specifically include a first limiting structure a and a second limiting structure b. The first limiting structure a is connected to the second base 5 and is capable of abutting against the first base 1 to limit the maximum rotation angle of the second base 5 along a first rotation direction d. Furthermore, the second limiting structure b is connected to the second base 5 and is capable of abutting against the first base 1 to limit the maximum rotation angle of the second base 5 along a second rotation direction c. It should be noted that the second rotation direction c is opposite to the first rotation direction d.

[0082] It can be seen that by providing the first limiting structure a and the second limiting structure b, the rotatable angle of the second seat body 5 is limited to a certain range.

[0083] In working equipment such as tractors, the first seat 1 of the damping hinge can be connected to the side of the cab, and the inner end of the long arm of the rearview mirror assembly is connected to the second seat 5 of the damping hinge, and the outer end of the long arm is connected to the rearview mirror. Figure 2 The state of the middle damping hinge is regarded as the open state of the damping hinge. At this time, the rearview mirror is open and the personnel in the cab can observe the situation behind the cab side through the rearview mirror. Figure 3 The state of the middle damping hinge is regarded as the closed state of the damping hinge, in which case the rearview mirror is closed. For example, when the tractor is parked, the rearview mirror can be closed.

[0084] In some embodiments, reference Figure 2 、 Figure 3 and Figure 7 The first limiting structure a can be provided with a first card slot, the second limiting structure b can be provided with a second card slot, and the second base body 5 can be provided with a first card plate inserted into the first card slot and a second card plate inserted into the second card slot. Figure 7 In the figure, the first and second clamping plates are both labeled as clamping plate n. In addition, the peripheral wall of the rotating disk 11 abuts against the first and second limiting structures a and b toward the first and second clamping plates, so that the rotating disk 11 can support the first and second limiting structures a and b, preventing the first and second limiting structures a and b from falling out of the second base 5. In this case, no additional fixing structure is required to fix the first and second limiting structures a and b, which helps to simplify the structure of the damping hinge and improve its compactness.

[0085] Reference Figure 4 The damping hinge may further include components such as a bushing 22, an anti-rotation washer 23, and a fastener 24. Specifically, the bushing 22 is embedded and fixed in the first base 1, and the rotating shaft 21 rotatably passes through the bushing 22. The anti-rotation washer 23 and the fastener 24 (such as a lock nut that can form a threaded fit with the rotating shaft 21) are usually combined and fixedly sleeved on the rotating shaft 21.

[0086] In addition, refer to Figure 4 、 Figure 6 and Figure 7 The rotating shaft 21 may be provided with an anti-rotation column section k (for example, a square column section), and the second seat body 5 may be provided with an anti-rotation hole o (for example, a square hole). The anti-rotation column section k is passed through the anti-rotation hole o, and an anti-rotation fitting position f is formed at the contact position between the anti-rotation column section k and the anti-rotation hole o, which can realize the circumferential fixation of the rotating shaft 21 and the second seat body 5, so that the rotating shaft 21 can be driven to rotate by the second seat body 5.

[0087] A second exemplary embodiment of the present application further provides an operating device, which can be agricultural machinery such as a tractor, or engineering machinery, emergency rescue machinery, etc. Specifically, the operating device includes a vehicle body, a rearview mirror assembly, and the aforementioned damping hinge, wherein a first base 1 of the damping hinge is connected to the vehicle body, and a second base 5 is connected to the rearview mirror assembly.

[0088] As previously mentioned, when the damping hinge of this application is used to connect the rearview mirror assembly of a tractor or other working equipment, the risk of the rearview mirror assembly shaking can be effectively reduced, thereby preventing normal operation from being affected. In addition, the working equipment of this application should also have other technical effects brought about by the damping hinge, which have been described in detail above and will not be repeated here.
