[0050] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present utility model will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.
[0051] like Figures 1 to 5 As shown, an embodiment of the utility model provides a buffer device, which includes at least two anti-collision structures 10 and a buffer component 20. One of two adjacent anti-collision structures 10 among the at least two anti-collision structures 10 is movably arranged on the other of the two adjacent anti-collision structures 10 so that one of the two adjacent anti-collision structures 10 moves to an initial position or a buffer position; one end of the buffer component 20 is connected to or abuts against one of the two adjacent anti-collision structures 10, and the other end of the buffer component 20 is connected to or abuts against the other of the two adjacent anti-collision structures 10.
[0052] Among them, when one of the two adjacent anti-collision structures 10 is in the initial position, the contact surface of one of the two adjacent anti-collision structures 10 protrudes from the contact surface of the other of the two adjacent anti-collision structures 10 and contacts with the structure to be buffered; when one of the two adjacent anti-collision structures 10 is in the buffering position, the contact surface of one of the two adjacent anti-collision structures 10 is flush with the contact surface of the other of the two adjacent anti-collision structures 10, so that the contact surface of one of the two adjacent anti-collision structures 10 and the contact surface of the other of the two adjacent anti-collision structures 10 are both in contact with the structure to be buffered.
[0053] The buffer device provided by this embodiment can effectively buffer the structure to be buffered by setting at least two anti-collision structures 10 and a buffer 20. When the structure to be buffered with a certain speed begins to contact the anti-collision structure, one of the two adjacent anti-collision structures 10 is impacted and the buffer 20 begins to compress. After one of the two adjacent anti-collision structures 10 reaches the buffering position under the impact, the structure to be buffered will contact the contact surface of the two adjacent anti-collision structures at the same time. At this time, the force-bearing area of the buffer device increases, and the impact force and vibration received are further reduced. If the structure to be buffered has not stopped moving, the next anti-collision structure 10 adjacent to the other of the two adjacent anti-collision structures will continue to bear the impact and play a buffering effect until the structure to be buffered stops moving, thereby playing an effective shock absorption and anti-collision effect on the structure to be buffered. In addition, the buffer device can configure the number of anti-collision structures 10 according to different impact conditions, so that it can be flexibly applied to different buffering demand scenarios, ensuring a good buffering effect. Therefore, the buffer device provided by this embodiment can solve the technical problem of poor buffering effect of the buffer device in the prior art.
[0054] Specifically, the buffer device further includes an anti-collision pad 30, which is arranged on the other of the two adjacent anti-collision structures, and the anti-collision pad 30 is made of a buffer material. When the anti-collision pad 30 is in the initial state, at least part of the anti-collision pad 30 protrudes from the contact surface of the other of the two adjacent anti-collision structures. With such a structural arrangement, the buffering effect of the buffer device can be further enhanced through the buffering effect of the anti-collision pad 30, and the buffering efficiency can be further improved through the joint action of the anti-collision pad 30 and the buffer member 20.
[0055] Specifically, the crash pad 30 may be made of a rubber material.
[0056] Specifically, another of the two adjacent anti-collision structures is provided with an installation groove, which is adapted to the shape of the anti-collision pad 30, and the anti-collision pad 30 is installed in the installation groove. In this way, when installing the anti-collision pad 30, accurate positioning can be achieved, the installation efficiency is improved, and it is convenient to ensure that the anti-collision pad 30 effectively plays a buffering effect.
[0057] Specifically, the anti-collision pad 30 is an annular pad. With such a configuration, the anti-collision pad 30 can match the shape of the annular buffer device, so that the anti-collision pad 30 can better cooperate with the buffer device to achieve a buffering effect.
[0058] Specifically, at least two anti-collision structures 10 are detachably connected. With such a structural setting, the anti-collision structures can be detachably connected to each other, which can facilitate the rapid assembly and disassembly of the anti-collision structures, and help to set a buffer device with different numbers of anti-collision structures according to different buffering requirements, thereby effectively ensuring the buffering effect of the buffer device and further improving the application flexibility of the buffer device.
[0059] Specifically, another of the two adjacent anti-collision structures is provided with an avoidance opening groove, the avoidance opening groove is adapted to the shape of one of the two adjacent anti-collision structures, and one of the two adjacent anti-collision structures is movably provided at the avoidance opening groove. With such a structural setting, buffering cooperation between multiple anti-collision structures can be achieved through the setting of the avoidance opening groove, so that the anti-collision structure can move from the initial position to the buffering position under the impact, and in the process of movement, combined with the function of the buffering member 20, it plays an effective buffering role on the structure to be buffered.
[0060] Specifically, a first limiting portion is provided on one of the two adjacent anti-collision structures, and a second limiting portion cooperating with the first limiting portion is provided on the other of the two adjacent anti-collision structures. When one of the two adjacent anti-collision structures is in the initial position, the first limiting portion and the second limiting portion abut against each other to limit; when one of the two adjacent anti-collision structures is in the buffer position, the first limiting portion and the second limiting portion are spaced apart. With such a structural arrangement, the two adjacent anti-collision structures can be prevented from being disengaged from each other in the initial position through the cooperation between the first limiting portion and the second limiting portion, and can also be prevented from being disengaged from each other under the rebound action of the buffer member 20 in the process of the anti-collision structure moving from the buffer position to the initial position after the impact stops, thereby effectively ensuring the structural stability of the buffer device. Specifically, the first limiting portion and the second limiting portion can be limiting protrusions.

In this way, the moving direction of the first anti-collision structure 11 can be stabilized by the limiting effect of the first guide groove 1131, ensuring that the first anti-collision structure 11 can stably move at the first avoiding opening groove 1231, thereby further ensuring the stabilizing effect of the buffer device.

[0064] Specifically, there are multiple first anti-collision protrusions 113, and the multiple first anti-collision protrusions 113 are arranged at intervals around the periphery of the first anti-collision body 112.

[0071] Specifically, the elastic coefficient of the second buffer 22 is greater than the elastic coefficient of the first buffer 21. In this way, when the structure to be buffered with a certain speed begins to contact the first anti-collision structure 11, the first buffer 21 begins to compress, and the second buffer also begins to compress at the same time. However, the compression stroke of the first anti-collision structure 11 is greater than the compression stroke of the second anti-collision structure 12, which will prioritize the first anti-collision structure 11 to be in the first buffering position, thereby facilitating better contact and buffering with the structure to be buffered through the contact surface of the first anti-collision structure 11 and the contact surface of the second anti-collision structure 12, thereby effectively improving the buffering effect.
[0072] In this embodiment, the buffer device includes a plurality of anti-collision structures 10, at least two buffer members 20, and one buffer member 20 is arranged on two adjacent anti-collision structures 10. Among them, the elastic coefficient of one of the two adjacent buffer members 20 that is close to the structure to be buffered is smaller than the elastic coefficient of one of the two adjacent buffer members 20 that is far from the structure to be buffered. With such a structural setting, it is easy to ensure that the elastic coefficients of at least two buffer members 20 in the direction away from the structure to be buffered increase step by step, which will make the compression stroke of one of the two adjacent buffer members 20 that is close to the structure to be buffered greater than the compression stroke of one of the two adjacent buffer members 20 that is far from the structure to be buffered. In this way, it can be effectively ensured that the buffer member 20 that is closer to the structure to be buffered among the two adjacent buffer members 20 has a sufficient compression stroke and moves to the corresponding buffer position first, so as to effectively ensure the buffering effect.
[0073] Specifically, the first buffer member 21 and the second buffer member 22 are made of springs or nylon.
[0074] Specifically, the first mounting base plate 125 is detachably disposed on the second anti-collision structure 12; the second mounting base plate 133 is detachably disposed on the third anti-collision body 131. In this way, the anti-collision structure can be disassembled by disassembling the base plate, so that the anti-collision structures are detachably connected, and the number of anti-collision structures is increased or decreased, so that the buffer device can more flexibly adapt to different impact conditions, ensure the buffering effect, and improve the buffering efficiency.
[0075] The specific working principle of the buffer device provided in the embodiment of the utility model is: when an object with a certain speed begins to contact the front anti-collision structure (equivalent to the first anti-collision structure 11), the anti-collision material of the front anti-collision structure (equivalent to the first buffer 21) begins to compress, and at the same time, the anti-collision material (equivalent to the second buffer 22) of the middle anti-collision structure (equivalent to the second anti-collision structure 12) also begins to compress, but the compression stroke of the front end is larger than the compression stroke of the middle. If the object still has speed, the front anti-collision structure first reaches the limit position (equivalent to the buffer position), and then the object contacts the anti-collision pad and the middle anti-collision structure. At this time, the force area of the equipment where the buffer device is installed begins to increase, and the impact force and vibration received begin to decrease. If the object has not stopped moving, the middle anti-collision structure will contact the anti-collision pad and the end anti-collision structure (equivalent to the third anti-collision structure 13) again after being gradually compressed to the limit position (equivalent to the buffer position). At this time, the force area of the equipment where the buffer device is installed is further increased, and the impact force and vibration received are further reduced. And so on, until the object stops moving.
[0076] From the above description, it can be seen that the above embodiments of the utility model achieve the following technical effects:
[0077] 1. A multi-level buffer structure is designed, which can configure the number of anti-collision structures in the buffer device according to different impact conditions. The number can be increased when the impact force is large, and the number can be reduced when the impact force is opposite. The device can reduce the impact force more flexibly, more conveniently and more efficiently.
[0078] 2. A variety of cushioning materials are used to enhance the ability to absorb impact energy, effectively cushion moving parts, reduce impact effects, and improve equipment stability.
[0079] 3. During the application process, the buffer device will gradually increase the force-bearing area of the contact surface with the structure to be buffered under the action of impact force. Increasing the force-bearing area can effectively reduce the impact force and impact intensity, thereby providing a better buffering effect.
[0080] 4. Each anti-collision structure is connected and limited by blocks, and the number can be flexibly adjusted according to the impact conditions. The structure is easy to disassemble and install.
