Description

Technical Field

[0001] The utility model relates to the technical field of robot anti-collision, in particular to a buffer mechanism and an intelligent robot. Background Art

[0002] With the rapid development of modern technology, the application scope of intelligent robots is becoming more and more extensive. Whether at home or in public places such as shopping malls and banks, the figures of intelligent robots can be seen. During the use of intelligent robots, it is inevitable to collide with other objects.

[0003] In the related art, an intelligent robot is provided with an anti-collision plate and a buffer mechanism. The anti-collision plate is elastically connected to the device main body of the intelligent robot through the buffer mechanism. In the related art, an elastic member is used as the buffer mechanism, and the anti-collision plate buffers the acting force of the obstacle colliding with the device main body through the elastic deformation of the elastic member to avoid the risk of damage to the device main body.

[0004] However, the anti-collision plate is directly fixedly connected to the device main body through the elastic member. Therefore, the elastic member also needs to support the anti-collision plate, which requires the elastic member to have a certain rigidity. However, the greater the rigidity of the elastic member means the worse the elastic deformation ability of the elastic member, resulting in the worse ability of the anti-collision plate to buffer the external force impact deformation. Therefore, the intelligent robot is easily subjected to a greater impact force. Therefore, the anti-collision performance of the intelligent robot in the related art is poor. Summary of the Utility Model

[0005] The utility model discloses a buffer mechanism and an intelligent robot to solve the problem of poor anti-collision performance of the intelligent robot.

[0006] To solve the above problems, the utility model adopts the following technical solutions:

[0007] A buffer mechanism is applied to an intelligent robot. The buffer mechanism includes an anti-collision plate connection bracket, a body connection bracket, a rigid connecting member, and an elastic member;

[0008] One end of the rigid connecting member is hinged to the anti-collision plate connection bracket, the other end of the rigid connecting member is hinged to the body connection bracket, one end of the elastic member is connected to the body connection bracket, and the other end of the elastic member is connected to the rigid connecting member; wherein, the anti-collision plate connection bracket is used for fixedly connecting with the anti-collision plate of the intelligent robot, and the body connection bracket is used for fixedly connecting with the device main body of the intelligent robot.

[0009] An intelligent robot includes a device main body, an anti-collision plate, and the above buffer mechanism. The anti-collision plate connection bracket of the buffer mechanism is fixedly connected to the anti-collision plate, and the body connection bracket of the buffer mechanism is fixedly connected to the device main body.

[0010] The technical solution adopted by the utility model can achieve the following beneficial effects:

[0011] In the buffer mechanism disclosed by the utility model, when the anti-collision plate encounters the impact of an obstacle, the anti-collision plate connecting bracket and the rigid connecting piece rotate relative to each other, and at the same time, the rigid connecting piece and the body connecting bracket also rotate relative to each other. During the rotation of the rigid connecting piece, the elastic member undergoes elastic deformation, so as to buffer the impact force of the obstacle hitting the equipment main body, and thus play a role in preventing the intelligent robot from colliding. In this solution, the anti-collision plate and the equipment main body are connected by a rigid connecting piece to ensure the firm and reliable connection between the anti-collision plate and the equipment main body. At the same time, an elastic member is arranged between the rigid connecting piece and the body connecting bracket, and the elastic member can buffer the impact force. Therefore, the anti-collision plate and the equipment main body can better resist the impact force of the obstacle. Therefore, the solution disclosed in this application can not only ensure the connection reliability between the anti-collision plate and the equipment main body, but also ensure that the anti-collision plate and the equipment main body have good buffering performance, so that the intelligent robot has good anti-collision performance.

Detailed implementation manners

[0019] To make the objectives, technical solutions and advantages of the present utility model clearer, the technical solutions of the present utility model will be clearly and completely described below in conjunction with specific embodiments of the present utility model and the corresponding drawings. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts fall within the scope of protection of the present utility model.

[0020] The following will, with reference to the drawings, detail the technical solutions disclosed in each embodiment of the present utility model.

[0021] As Figures 1 to 6 shown, an embodiment of the present utility model discloses a buffer mechanism 100, which is applied to an intelligent robot. The intelligent robot includes a device main body and an anti - collision plate, and the anti - collision plate is connected to the device main body through the buffer mechanism 100. Here, the device main body includes, but is not limited to, a frame, a circuit component, and a functional component. The buffer mechanism 100 can be connected to the frame. The disclosed buffer mechanism 100 includes an anti - collision plate connection bracket 110, a body connection bracket 120, a rigid connection member 130, and an elastic member 140.

[0022] The anti-collision plate connecting bracket 110 is used for fixedly connecting with the anti-collision plate. At this time, there is no relative movement between the anti-collision plate connecting bracket 110 and the anti-collision plate. Therefore, the anti-collision plate connecting bracket 110 and the anti-collision plate can be regarded as a whole component. In one solution, the anti-collision plate can be fixedly connected with the anti-collision plate connecting bracket 110 by mechanical connection methods such as welding, riveting, and threaded connection. Or, in another solution, the anti-collision plate can be integrally formed with the anti-collision plate connecting bracket 110. The body connecting bracket 120 is used for fixedly connecting with the equipment main body. At this time, the body connecting bracket 120 is fixedly connected with the frame of the equipment main body. There is no relative movement between the body connecting bracket 120 and the frame. Therefore, the body connecting bracket 120 and the frame can be regarded as a whole component. In one solution, the body connecting bracket 120 can be fixedly connected with the frame by mechanical connection methods such as welding, riveting, and threaded connection. Or, in another solution, the body connecting bracket 120 can be integrally formed with the body.

[0023] One end of the rigid connecting member 130 is hinged to the anti-collision plate connecting bracket 110, and the other end of the rigid connecting member 130 is hinged to the body connecting bracket 120. The rigid connecting member 130 here is made of a rigid material and is not easily bent. Therefore, the rigid connecting member 130 has good supporting performance. Since the anti-collision plate connecting bracket 110 and the body connecting bracket 120 are respectively fixedly connected to the anti-collision plate and the equipment main body, the rigid connecting member 130 can realize the rigid connection between the anti-collision plate and the equipment main body, so that the buffer mechanism 100 has good supporting performance for the anti-collision plate.

[0024] One end of the rigid connecting member 130 is hinged to the anti-collision plate connecting bracket 110. At this time, the anti-collision plate connecting bracket 110 has a rotational degree of freedom relative to the rigid connecting member 130. Therefore, the anti-collision plate has a rotational degree of freedom relative to the rigid connecting member 130. When the anti-collision plate is impacted by an obstacle, the anti-collision plate and the anti-collision plate connecting bracket 110 can rotate relative to the rigid connecting member 130 at a certain angle.

[0025] The other end of the rigid connecting member 130 is hinged to the body connecting bracket 120. At this time, the body connecting bracket 120 has a rotational degree of freedom relative to the rigid connecting member 130. One end of the elastic member 140 is connected to the body connecting bracket 120, and the other end of the elastic member 140 is connected to the rigid connecting member 130. At this time, the rigid connecting member 130 is elastically connected to the body connecting bracket 120 and the equipment main body. When the anti-collision plate is impacted by an obstacle, the rigid connecting member 130 rotates relative to the body connecting bracket 120 and the equipment main body. At this time, the elastic member 140 undergoes elastic deformation during the rotation of the rigid connecting member 130, so as to be able to buffer the impact force of the obstacle colliding with the equipment main body, and thus play a role in preventing the intelligent robot from colliding.

[0026] During the specific operation process, when the anti-collision plate is impacted by an obstacle, the anti-collision plate and the anti-collision plate connection bracket 110 can rotate relative to the rigid connection member 130 at a certain angle. At the same time, the rigid connection member 130 also rotates relative to the body connection bracket 120 and the equipment main body at a certain angle. During the rotation of the rigid connection member 130, the elastic member 140 can be compressed, and the elastic member 140 can absorb the impact force, thereby offsetting the impact force of the obstacle on the anti-collision plate, and further making the impact force received by the equipment main body smaller. That is to say, the translational movement of the anti-collision plate relative to the equipment main body can be realized through the articulated rigid connection member 130, and the translational movement of the anti-collision plate is buffered by the elastic member 140.

[0027] In the embodiment disclosed in the present application, the anti-collision plate and the equipment main body are connected by a rigid connection member 130 to ensure the firm and reliable connection between the anti-collision plate and the equipment main body. At the same time, the rigid connection member 130 is hinged and elastically connected to the body connection bracket 120 through the rigid connection member 130 and the elastic member 140, so that the impact force can be buffered. Therefore, the anti-collision plate and the equipment main body can better resist the impact force of the obstacle. Therefore, the solution disclosed in the present application can not only ensure the connection reliability between the anti-collision plate and the equipment main body, but also ensure that the anti-collision plate and the equipment main body have good buffering performance, so that the intelligent robot has good anti-collision performance.

[0028] In the above embodiment, the rigid connection member 130 and the anti-collision plate connection bracket 110 and the body connection bracket 120 can be hinged through components such as a rotating shaft, a hinge, and a hinge. At this time, the rotating shaft, the hinge, and the hinge can realize the rotation of the rigid connection member 130 and the anti-collision plate connection bracket 110 and the body connection member at a certain angle and direction. That is to say, the rotation angle and direction of the rigid connection member 130 and the anti-collision plate connection bracket 110 and the body connection bracket 120 need to be set according to the specific collision direction.

[0029] In another alternative solution, the rigid connection member 130 may include a first ball head 131, a support rod 132, and a second ball head 133. The first end of the support rod 132 may be fixedly connected to the first ball head 131, and the second end of the support rod 132 may be fixedly connected to the second ball head 133. Here, the support rod 132 may be integrally formed with the first ball head 131 and the second ball head 133. Of course, the support rod 132 may be fixedly connected to the first ball head 131 and the second ball head 133 by welding, riveting, threaded connection, etc.

[0030] The anti-collision plate connection bracket 110 is provided with a first accommodation space 1101. At least part of the first ball head 131 can be located within the first accommodation space 1101, and the first ball head 131 can rotate relative to the anti-collision plate connection bracket 110. At this time, since the first ball head 131 is spherical in structure, the first ball head 131 and the anti-collision plate connection bracket 110 can achieve universal rotation. It can be understood here that the first accommodation space 1101 restricts the translational freedom of the first ball head 131 but does not restrict its rotational freedom. Therefore, the first ball head 131 can rotate in any direction within the first accommodation space 1101. Thus, the support rod 132 can be hinged to the anti-collision plate connection bracket 110 through the first ball head 131. The first ball head 131 here is the hinge component. The first accommodation space 1101 has an opening, and the first end of the support rod 132 can extend into the opening, so that the first end of the support rod 132 is connected to the first ball head 131. Or, part of the first ball head 131 extends out of the anti-collision plate connection bracket 110 through the opening, so that the first end of the support rod 132 is connected to the first ball head 131.

[0031] Similarly, the body connection bracket 120 is provided with a second accommodation space 1201. At least part of the second ball head 133 can be located within the second accommodation space 1201, and the second ball head 133 can rotate relative to the body connection bracket 120. At this time, since the second ball head 133 is spherical in structure, the second ball head 133 and the body connection bracket 120 can achieve universal rotation. It can be understood here that the second accommodation space 1201 restricts the translational freedom of the second ball head 133 but does not restrict its rotational freedom. Therefore, the second ball head 133 can rotate in any direction within the second accommodation space 1201. Thus, the support rod 132 can be hinged to the body bracket through the second ball head 133. The second ball head 133 here is the hinge component. The second accommodation space 1201 has an opening, and the second end of the support rod 132 can extend into the opening, so that the second end of the support rod 132 is connected to the second ball head 133. Or, part of the second ball head 133 extends out of the body connection bracket 120 through the opening, so that the second end of the support rod 132 is connected to the second ball head 133.

[0032] In this solution, the first ball head 131 and the second ball head 133 can achieve the universal rotation of the rigid connecting member 130 with the anti-collision plate connection bracket 110 and the body connection bracket 120, thus not restricting the collision direction of the obstacle. Therefore, the structure of the buffer mechanism 100 is simplified, so that the buffer mechanism 100 of the same structure can be used for the anti-collision plates in any direction of the intelligent robot, without adjusting the rotation angle and direction of the buffer mechanism 100. Therefore, the manufacturing cost of the intelligent robot is reduced.

[0033] Optionally, the elastic member 140 may be arranged in parallel with the support rod 132. At this time, the support rod 132 and the elastic member 140 are arranged in parallel on the body connection bracket 120. One end of the elastic member 140 facing away from the body connection bracket 12 is connected to the support rod 132. Alternatively, in the present application, the elastic member 140 may also be connected to the second ball head 133.

[0034] In another alternative embodiment, the elastic member 140 may be sleeved on the outer side of the support rod 132, and one end of the elastic member 140 facing away from the body connection bracket 120 may be connected to the support rod 132. This solution can reduce the occupied volume of the elastic member 140, thereby reducing the volume of the buffer mechanism 100.

[0035] In the above embodiments, the elastic member 140 may be an elastic structure such as a spring or a foam. Of course, the elastic member 140 may also be other elastic structures, which are not limited herein.

[0036] In another solution, in the direction from the first end of the support rod 132 to the second end of the support rod 132, the cross-sectional area of the elastic member 140 gradually increases in a direction perpendicular to the axis of the support rod 132. That is to say, in the direction from the first end of the support rod 132 to the second end of the support rod 132, the elastic member 140 is an increasing structure. Here, it can also be understood that the elastic member 140 is a tower-shaped structure or a conical structure. At this time, the end face area of the end of the elastic member 140 connected to the body connection bracket 120 is larger, and the end face area of the end of the elastic member 140 connected to the support rod 132 is smaller.

[0037] In this solution, since the end face area of the end of the elastic member 140 connected to the body connection bracket 120 is larger, the elastic member 140 has a higher connection strength with the body connection bracket 120. Therefore, the elastic member 140 has better support performance for the support rod 132, and thus can further improve the support performance for the anti-collision plate, and further avoid the problem of insufficient support performance for the anti-collision plate.

[0038] Optionally, the elastic member 140 may be a spring. At this time, in the direction from the first end of the support rod 132 to the second end of the support rod 132, the circumference, area or diameter of each turn of the spring wire gradually increases. Alternatively, the elastic member 140 may be an elastic sleeve. The cross-sectional shape of the elastic member 140 may be circular, elliptical, rectangular, or racetrack-shaped. Of course, the cross-sectional shape of the elastic member 140 may also be other shapes, which are not limited herein.

[0039] In the above embodiments, one end of the elastic member 140 facing away from the body connection bracket 120 may be connected to the outer side wall of the support rod 132.

[0040] In another solution, an annular protrusion 1321 may be provided on the outer sidewall of the support rod 132, and one end of the elastic member 140 facing away from the body connection bracket 120 may be connected to the annular protrusion 1321. In this solution, one end of the elastic member 140 can directly abut against the annular protrusion 1321, thereby simplifying the connection manner between the support rod 132 and the elastic member 140, and further simplifying the structure of the buffer mechanism 100, so that the assembly manner of the buffer mechanism 100 is more simple and reliable.

[0041] Optionally, the annular protrusion 1321 and the support rod 132 may be of a split structure, that is to say, the annular protrusion 1321 may be sleeved on the outer sidewall of the support rod 132 and then connected by a connecting component. Alternatively, the annular protrusion 1321 and the support rod 132 may be integrally formed.

[0042] In the above embodiment, the first accommodation space 1101 may be a through hole or a groove. At this time, when the first ball head 131 is installed in the first accommodation space 1101, it is necessary to limit the position at the port of the through hole or the notch of the groove to avoid the risk of the first ball head 131 detaching from the first accommodation space 1101.

[0043] In another alternative embodiment, the anti-collision plate connecting frame may include a first bracket 111 and a first cover 112. The first bracket 111 and the first cover 112 are connected. The first bracket 111 may be provided with a first through hole 111a, and the first cover 112 may be formed with a first groove 112a. The first port of the first through hole 111a may be disposed opposite to the support rod 132. Here, the first port of the first through hole 111a is the opening of the first accommodation space 1101. The second port of the first through hole 111a may be disposed opposite to the notch of the first groove 112a, and the first groove 112a and the first through hole 111a may form the first accommodation space 1101. In the axial direction of the first through hole 111a, the orthographic projection area of the first ball head 131 may be smaller than the orthographic projection area of the first groove 112a and the orthographic projection area of the second port of the first through hole 111a, and the orthographic projection area of the first ball head 131 may be greater than the orthographic projection area of the first port of the first through hole 111a.

[0044] At this time, since the orthographic projection area of the first groove 112a and the orthographic projection area of the second port of the first through hole 111a are larger than the orthographic projection area of the first ball head 131, the first ball head 131 can be normally inserted into the first groove 112a and the first through hole 111a. At the same time, since the orthographic projection area of the first ball head 131 is larger than the orthographic projection area of the first port of the first through hole 111a, the first ball head 131 will not fall out from the first port of the first through hole 111a. Therefore, the first ball head 131 can be limited in the first accommodation space 1101. Here, it can also be understood that the diameter of the first ball head 131 is smaller than the diameter of the first port of the first through hole 111a.

[0045] In this solution, by restricting the opening of the first accommodation space 1101 itself, there is no need to additionally provide a limiting structure, thus further simplifying the structure of the buffer mechanism 100.

[0046] In the above solution, the first ball head 131 needs to be first inserted into the first accommodation space 1101. Therefore, at least one of the first ball head 131 and the second ball head 133 needs to be integrally formed with the support rod 132. For example, when the first ball head 131 is integrally formed with the support rod 132 and the second ball head 133 is integrally formed with the support rod 132, the first ball head 131 can be first inserted into the first through hole 111a, then the first cover 112 is covered, the first cover 112 and the first bracket 111 are connected, and finally the support rod 132 is connected to the first ball head 131. When the second ball head 133 is integrally formed with the support rod 132 and the first ball head 131 is integrally formed with the support rod 132, the support rod 132 passes through the first through hole 111a, so that the first ball head 131 is located in the first through hole 111a, then the first cover 112 is covered, the first cover 112 and the first bracket 111 are connected, and finally the support rod 132 is connected to the second ball head 133. When both the first ball head 131 and the second ball head 133 are integrally formed with the support rod 132, the first ball head 131 can be first inserted into the first through hole 111a, then the first cover 112 is covered, the first cover 112 and the first bracket 111 are connected, and finally the support rod 132 is connected to the first ball head 131 and the second ball head 133. Of course, the support rod 132 can also be divided into two parts. One part is integrally formed with the first ball head 131, and the other part is integrally formed with the second ball head 133. After the first ball head 131 is installed in the first accommodation space 1101, the two divided parts of the support rod 132 are then connected.

[0047] Similarly, the body connection bracket 120 may include a second bracket 121 and a second cover 122. The second bracket 121 is provided with a second through hole 121a, and the second cover 122 is formed with a second groove 122a. The first port of the second through hole 121a may be disposed opposite to the support rod 132, the second port of the second through hole 121a may be disposed opposite to the notch of the second groove 122a, and the second groove 122a and the second through hole 121a may form a second accommodation space 1201. In the axial direction of the second through hole 121a, the orthographic projection area of the second ball head 133 may be smaller than the orthographic projection area of the second groove 122a and the orthographic projection area of the second port of the second through hole 121a, and larger than the orthographic projection area of the first port of the second through hole 121a.

[0048] At this time, since the orthographic projection area of the second groove 122a and the orthographic projection area of the second port of the second through hole 121a are larger than the orthographic projection area of the second ball head 133, the second ball head 133 can be normally installed in the second groove 122a and the second through hole 121a. At the same time, since the orthographic projection area of the second ball head 133 is larger than the orthographic projection area of the first port of the second through hole 121a, the second ball head 133 will not fall out from the first port of the second through hole 121a. Therefore, the second ball head 133 can be limited in the second accommodation space 1201. It can also be understood here that the diameter of the second ball head 133 is smaller than the diameter of the first port of the second through hole 121a.

[0049] In this solution, by restricting the opening of the second accommodation space 1201 itself, there is no need to additionally provide a limiting structure, thereby further simplifying the structure of the buffer mechanism 100.

[0050] The installation method of the second ball head 133 here is the same as that of the first ball head 131, so it will not be elaborated in this article.

[0051] Optionally, the first bracket 111 and the first cover 112 may be connected by a third fastener 113. The third fastener 113 here may be a threaded member such as a bolt or a screw, and of course, it may also be a rivet. The second bracket 121 and the second cover 122 may be connected by a fourth fastener 123. The fourth fastener 123 here may be a threaded member such as a bolt or a screw, and of course, it may also be a rivet.

[0052] At least one of the first bracket 111 and the first cover 112 in the above embodiments may be fixedly connected to the anti-collision plate. Such as Figure 1As shown, the first bracket 111 can be fixedly connected to the anti-collision plate by a fifth fastener 150, where the fifth fastener 150 can be a threaded member such as a bolt, a screw, or a rivet. At least one of the second bracket 121 and the second cover 122 can be fixedly connected to the device body. Specifically, the second bracket 121 can be fixedly connected to the device body by a sixth fastener, where the sixth fastener can be a threaded member such as a bolt, a screw, or a rivet. For example, a threaded hole 121b is provided on the second bracket 121, and the sixth fastener passes through the device body and is threadedly connected to the threaded hole 121b.

[0053] In one solution, the rigid connector 130 further includes a first fastener 134 and a second fastener 135, and the first ball head 131 can be fixedly connected to the support rod 132 via the first fastener 134. The second ball head 133 can be fixedly connected to the support rod 132 via the second fastener 135. At this time, the first ball head 131 and the second ball head 133 are both provided with connecting holes, and the first fastener 134 is connected to the support rod 132 through the connecting hole on the first ball head 131, and the second fastener 135 is connected to the support rod 132 through the connecting hole on the second ball head 133. The first fastener 134 and the second fastener 135 here can be threaded parts such as bolts and screws, and of course, they can also be rivets.

[0054] In another alternative, if Figure 4 As shown, the first ball head 131 may be provided with a first stepped hole 131a, and one end facing the support rod 132 may pass through the first stepped hole 131a and be connected to the support rod 132, and the end of the first fastener 134 facing away from the support rod 132 is located in the first stepped hole 131a, and abuts against the stepped surface of the first stepped hole 131a. It can also be understood here that the cap body of the first fastener 134 abuts against the stepped surface. At this time, the first stepped hole 131a may include a first hole section and a second hole section that are connected, and the first hole section may be located on the side of the second hole section facing the support rod 132, and the cross-sectional area of ​​the first hole section is smaller than the cross-sectional area of ​​the second hole section, and the stepped surface of the above-mentioned first stepped hole 131a is the end face of the first hole section.

[0055] In this solution, the end of the first fastener 134 away from the support rod 132 does not protrude from the surface of the first ball head 131, so that the end of the first fastener 134 away from the support rod 132 is hidden in the first stepped hole 131a, thereby avoiding the risk of interference between the first fastener 134 and the first cover body 112.

[0056] Similarly, the second ball head 133 may be provided with a second stepped hole 133a. One end of the second fastener 135 facing the support rod 132 may pass through the second stepped hole 133a and be connected to the support rod 132. The end of the second fastener 135 facing away from the support rod 132 may be located within the second stepped hole 133a and abut against the stepped surface of the second stepped hole 133a.

[0057] In this solution, the end of the second fastener 135 facing away from the support rod 132 can be prevented from protruding beyond the surface of the second ball head 133, so that the end of the second fastener 135 facing away from the support rod 132 is hidden within the second stepped hole 133a, thus avoiding the risk of interference between the second fastener 135 and the second cover 122.

[0058] Furthermore, both the first fastener 134 and the second fastener 135 can be threaded parts. This solution facilitates the disassembly of the first ball head 131 and the second ball head 133 from the support rod 132, thereby improving the maintainability of the rigid connecting member 130.

[0059] In another alternative solution, a process groove 112b may be provided on the side of the first cover 112 facing away from the first ball head 131. The process groove 112b can insert a corresponding tool to adjust the position of the first cover 112 during assembly and connection of the anti-collision plate. The shape of the process groove 112b here can be a linear structure or a cross structure, and this is not limited in this text.

[0060] In another alternative embodiment, the anti-collision plate connecting bracket 110 and the rigid connecting member 130 can be elastically connected through an elastic reset member. For example, an elastic reset member can be sleeved on the support rod 132. One end of the elastic reset member is connected to the anti-collision plate connecting bracket 110, and the other end is connected to the support rod 132. At this time, the reset of the anti-collision plate can be achieved. In addition, the elastic reset member can also absorb part of the impact force, thereby further improving the anti-collision performance of the intelligent robot.
