[0037] In order to make the purpose, technical solution and advantages of the embodiment of the utility model clearer, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is a part of the embodiment of the utility model, not all the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the utility model.

[0038] The inventors have found in practice that the buffer components in the related art have the following main disadvantages: when a collision occurs under conditions where the transfer device has a high speed or a heavy weight, the buffer components are subjected to a large impact, making the buffer components easily damaged, resulting in a short service life of the buffer components.

[0039] In addition, the buffer component cannot achieve a step-by-step buffering effect, resulting in a poor buffering effect on the transfer device, that is, the buffer component cannot perform step-by-step buffering and deceleration on the transfer device, causing the transfer device to be subjected to a greater impact.

[0040] In order to solve or improve the problem that the buffer is subjected to a large impact and cannot be buffered step by step, a buffer device and a transfer device are provided in the embodiment of the utility model.

[0041] Combine the following Figures 1 to 6 , describing the buffer device provided in an embodiment of the utility model.

[0042] Specifically, the buffer device includes a mounting assembly 1 , a first buffer component 2 , a first sliding component 3 and an elastic component 4 .

[0043] The mounting assembly 1 is used to be connected to the side of the main body of the transfer device. Optionally, the main body includes a frame, and the mounting assembly 1 is connected to the side of the frame, for example, the mounting assembly 1 can be connected to the frame by a threaded fastener.

[0044] The first buffer member 2 is connected to the side of the mounting assembly 1 facing away from the main body, and the surface of the first buffer member 2 facing away from the main body forms a collision surface 202. The collision surface 202 is the surface of the first buffer member 2 for colliding with an object. Optionally, the first buffer member 2 is configured as a rubber member, a silicone member or a soft plastic member. Optionally, the first buffer member 2 can be connected to the mounting assembly 1 by bonding or threaded fastener connection.

[0045] The first sliding member 3 is slidably mounted on the mounting assembly 1. For example, a guide post or a guide hole is provided on the mounting assembly 1, and the first sliding member 3 is slidably matched with the guide post or the guide hole. The first sliding member 3 can slide beyond the impact surface 202, or slide back to the side of the impact surface 202 close to the main body. It can be understood that the first sliding member 3 can slide beyond the impact surface 202 means that at least part of the first sliding member 3 can exceed the impact surface 202.

[0046] The elastic member 4 connects the first sliding member 3 and the mounting assembly 1, and is used to drive the first sliding member 3 to exceed the impact surface 202. Optionally, the elastic member 4 is configured as a spring, and both ends of the spring abut against the first sliding member 3 and the mounting assembly 1, respectively.

[0047] In this embodiment, during use, the buffer device is installed on the main body of the transfer device. During the collision between the transfer device and the object, the first sliding member 3 exceeds the first buffer member 2 under the action of the elastic member 4, so the first sliding member 3 first contacts the object. During the contact between the first sliding member 3 and the object, the elastic member 4 is compressed, so that the elastic member 4 forms a primary buffer. As the elastic member 4 is compressed, when the first sliding member 3 slides and retracts to the side of the impact surface 202 close to the main body, the impact surface 202 contacts the object, the first buffer member 2 is deformed, and the first buffer member 2 and the elastic member 4 together form a secondary buffer.

[0048] In this way, the buffer device provided by the utility model can be connected to the main body of the transfer device through the installation component 1, and the first sliding member 3 is driven to exceed the impact surface 202 of the first buffer member 2 through the elastic member 4, so that the first sliding member 3 can compress the elastic member 4 to form a primary buffer. By arranging the first buffer member 2 on the side of the installation component 1 away from the main body, it can work together with the elastic member 4 to form a secondary buffer.

[0049] The primary buffering of the elastic member 4 can slow down the impact speed of the transfer device, thereby reducing the impact force on the first buffer member 2 and reducing the probability of damage to the first buffer member 2. The elastic member 4 and the first buffer member 2 form a secondary buffer together, so that the elastic member 4 and the first buffer member 2 can share the impact force with each other, thereby reducing the impact force on the first buffer member 2 and the elastic member 4 and reducing the probability of damage to the first buffer member 2 and the elastic member 4.

[0050] In addition, through the primary buffer and the secondary buffer, the buffer device can form a step-by-step buffering effect, making the stopping process of the transfer device smoother and with less impact.

[0051] In some embodiments provided by the present utility model, the buffer device further includes a second sliding member 5 and a lever assembly 6 .

[0052] The second sliding member 5 is slidably mounted on the mounting assembly 1 in a direction close to or away from the main body. For example, a guide post or a guide hole is provided on the mounting assembly 1, and the second sliding member 5 is slidably matched with the guide post or the guide hole. Optionally, the sliding path of the second sliding member 5 is parallel to the sliding path of the first sliding member 3.

[0053] The lever assembly 6 is rotatably connected to the mounting assembly 1. The lever assembly 6 connects the first sliding member 3 and the second sliding member 5, and can make the sliding directions of the first sliding member 3 and the second sliding member 5 opposite, that is, when the first sliding member 3 moves away from the main body, the second sliding member 5 approaches the main body, and when the first sliding member 3 approaches the main body, the second sliding member 5 moves away from the main body.

[0054] In the process of sliding of the first sliding member 3 , the second sliding member 5 does not exceed the impact surface 202 .

[0055] In this embodiment, during the collision process, the first sliding member 3 first contacts the object, and during the contact process between the first sliding member 3 and the object, the elastic member 4 is compressed, so that the elastic member 4 forms a primary buffer. As the elastic member 4 is compressed, when the first sliding member 3 slides and retracts to the side of the impact surface 202 close to the main body, the impact surface 202 contacts the object, the first buffer 2 is deformed, and the first buffer 2 and the elastic member 4 form a secondary buffer together. During the sliding process of the first sliding member 3, the first sliding member 3 drives the second sliding member 5 to slide in the direction away from the main body through the lever assembly 6, and when the ends of the first sliding member 3 and the second sliding member 5 away from the main body are flush, the first sliding member 3 and the second sliding member 5 both stop sliding, and the object can no longer compress the first buffer 2 and the elastic member 4.

[0056] In this way, by setting the second sliding member 5 and the lever assembly 6, during the process of an object compressing the first buffer member 2, when the first sliding member 3 and the second sliding member 5 are flush with one end away from the main body, the first sliding member 3 and the second sliding member 5 no longer move, thereby limiting the object and preventing the object from further compressing the first buffer member 2 or the elastic member 4, thereby achieving the effect of limiting the maximum deformation of the first buffer member 2 and the elastic member 4, and preventing the first buffer member 2 and the elastic member 4 from being damaged by excessive compression.

[0057] In addition, when the first sliding member 3 and the second sliding member 5 are flush, the object is limited in position. The first sliding member 3 and the second sliding member 5 act on the object together, and the action area is larger, thereby avoiding the problem of stress concentration.

[0058] refer to Figure 4 As shown, in some embodiments provided by the present invention, the first sliding member 3 corresponds to two second sliding members 5 , and the two second sliding members 5 are connected to the first sliding member 3 through corresponding lever assemblies 6 .

[0059] In this embodiment, when the two second sliding members 5 are flush with the first sliding member 3, the object can be limited. In this way, the three sliding members act on the object together, the action area is larger, and the problem of stress concentration is avoided. In addition, the space on both sides of the first sliding member 3 can be fully utilized to improve the space utilization rate of the buffer device.

[0060] Furthermore, the number of the first sliding members 3 is set to be multiple, and each first sliding member 3 has two second sliding members 5. Such a configuration allows multiple sliding members to act on the object together, with a larger action area, thereby avoiding the problem of stress concentration.

[0061] refer to Figure 5 As shown, in some embodiments provided by the present utility model, the lever assembly 6 includes a swing rod 601 and a sliding rod 602 .

[0062] The sliding rod 602 is provided in two numbers, and both sliding rods 602 are slidably connected to the swing rod 601, for example, the two sliding rods 602 are slidably sleeved on both ends of the swing rod 601. The swing rod 601 is rotationally connected to the mounting assembly 1, and the rotation center of the swing rod 601 is located between the first sliding member 3 and the second sliding member 5. The two sliding rods 602 are rotationally connected to the first sliding member 3 and the second sliding member 5, for example, the two sliding rods 602 are hinged to the first sliding member 3 and the second sliding member 5, respectively. In this way, during the sliding of the first sliding member 3, the second sliding member 5 can be driven to slide in the opposite direction by the lever assembly 6.

[0063] Of course, the lever assembly 6 is not limited to the above-mentioned swing rod 601 and sliding rod 602. For example, Figure 6As shown, in other embodiments provided by the utility model, the lever assembly 6 includes a swing rod 601. The swing rod 601 is rotatably connected to the mounting assembly 1, and the rotation center of the swing rod 601 is located between the first sliding member 3 and the second sliding member 5. The swing rod 601 is provided with a first slide groove 603 and a second slide groove 604, the first sliding member 3 is provided with a first guide portion that slidably cooperates with the first slide groove 603, and the second sliding member 5 is provided with a second guide portion that slidably cooperates with the second slide groove 604. In this way, during the sliding process of the first sliding member 3, the second sliding member 5 can also be driven by the lever assembly 6 to slide in the opposite direction.

[0064] Optionally, the first buffer member 2 is covered on the outside of the first sliding member 3 and the second sliding member 5, and the first buffer member 2 is provided with a through hole 201 for the first sliding member 3 and the second sliding member 5 to pass through. Such a configuration can improve the compactness of the buffer device.

[0065] In some embodiments provided by the present invention, the mounting assembly 1 includes a connecting seat 101 and a mounting seat 102 .

[0066] The connecting seat 101 is used to connect with the main body, for example, the connecting seat 101 can be connected with the main body through a threaded fastener. The mounting seat 102 is connected with the connecting seat 101, for example, the mounting seat 102 can be connected with the connecting seat 101 through a threaded fastener. The first buffer member 2, the first sliding member 3 and the elastic member 4 are all arranged on the mounting seat 102.

[0067] In this embodiment, the first buffer member 2, the first sliding member 3 and the elastic member 4 can be installed on the mounting seat 102 and after debugging, the mounting seat 102 can be connected to the connecting seat 101 to reduce the difficulty of assembling the buffer device. In addition, the mounting seat 102 and the main body can be connected through the connecting seat 101, and different connecting seats 101 can be set according to different types of transfer devices. In this way, the buffer device can be installed on the transfer device by simply selecting the corresponding connecting seat 101.

[0068] In some embodiments provided by the present invention, in the first direction, an extension portion 103 is provided at one end of the connection seat 101, and in the first direction, the extension portion 103 is used to cooperate with the main body in a limited manner. For example, the first direction is the height direction of the transfer device. The extension portion 103 is provided at the top end of the connection seat 101, and accordingly, the connection seat 101 can be fitted with the side wall of the main body, and the extension portion 103 is fitted with the top or top surface of the main body.

[0069] In this embodiment, the extension portion 103 cooperates with the main body limiter to prevent the connection seat 101 from sliding down along the side wall of the main body, thereby improving the connection strength between the buffer device and the transfer device.

[0070] Optionally, the connection seat 101 is configured as an integrated sheet metal structure, and the connection seat 101 is provided with a flange, and the flange forms the extension portion 103 .

[0071] In some embodiments provided by the present invention, the mounting assembly 1 further includes a supporting seat 104 , and the mounting seat 102 is connected to the connecting seat 101 via the supporting seat 104 .

[0072] Since the size of the items or equipment placed on the main body of the transfer device may exceed the side wall of the main body, in this embodiment, the mounting seat 102 and the connecting seat 101 are connected by the support seat 104, so that the size of the mounting seat 102 protruding from the side wall of the main body can be increased, so that the buffer device can exceed the side wall of the items or equipment placed on the main body, and the buffer device can play a role in buffering the impact with obstacles.

[0073] Optionally, the number of the supporting seats 104 is set to at least two to improve the connection strength between the mounting seat 102 and the connecting seat 101 .

[0074] Optionally, the support seat 104 and the mounting seat 102 as well as the support seat 104 and the connecting seat 101 are connected via threaded fasteners.

[0075] In some embodiments provided by the present invention, in the second direction, both ends of the mounting seat 102 are provided with barrier portions 105, the barrier portions 105 extend toward the connecting seat 101, and the supporting seat 104 is provided between the two barrier portions 105. For example, the second direction is the extension direction of the side edge of the main body.

[0076] Since the mounting seat 102 and the connecting seat 101 are connected via the supporting seat 104, there is a distance between the mounting seat 102 and the connecting seat 101. In this embodiment, by providing a blocking portion 105 at both ends of the mounting seat 102, objects can be prevented from entering the gap between the mounting seat 102 and the connecting seat 101 and causing hooking problems.

[0077] Optionally, along the direction from the mounting seat 102 to the connecting seat 101 , the two blocking portions 105 gradually move away from each other.

[0078] In some embodiments provided by the present invention, the mounting assembly 1 further includes a second buffer 106, and the second buffer 106 is disposed between the support seat 104 and the connecting seat 101. Optionally, the second buffer 106 is configured as a rubber member, a silicone member or a soft plastic member.

[0079] In this embodiment, by disposing the second buffer member 106 between the support seat 104 and the connection seat 101 , the impact transmitted between the support seat 104 and the connection seat 101 can be reduced, thereby further improving the buffering effect of the buffer device.

[0080] A transfer device is also provided in an embodiment of the utility model.

[0081] Specifically, the transfer device includes a main body and the buffer device as described above.

[0082] It should be noted that the transfer device includes a buffer device, and also includes all the above-mentioned advantages of the buffer device, so it will not be elaborated on.

[0083] Although the embodiments of the present invention are described in conjunction with the accompanying drawings, those skilled in the art may make various modifications and variations without departing from the spirit and scope of the present invention, and such modifications and variations are all within the scope defined in the present application.
