Description

Technical Field

[0001] The utility model relates to the technical field of robots, in particular to a radome and a mobile robot. Background Art

[0002] Mobile robots with raised laser radars, especially sweeping robots or floor cleaning robots, need to protect the radars, so a radar cover is set above the radars.

[0003] During the movement of the mobile robot, obstacles may appear in front of or above the mobile robot, affecting the movement of the mobile robot. Therefore, it is necessary to sense collisions and trigger switches through collisions to enable the mobile robot to avoid obstacles. In related technologies, a radome is connected to the robot through a rotating shaft. When the radome touches something, the radome rotates to trigger the switch. This results in complex assembly of the radome and a narrow sensing range, which is not conducive to multi-directional triggering. There is also a method of setting up multiple switches to sense collisions of radomes in different directions, but the cost is relatively high. Utility Model Content

[0035] The utility model provides a radar cover.

[0036] See also Figures 3 to 5 In one embodiment of the utility model, the radome comprises:

[0037] A radome 10, wherein a side of the radome 10 is provided with an abutment platform 30;

[0038] A base 20, on which the radar cover 10 is mounted, and on which a micro switch facing the radar cover 10 is disposed;

[0039] Among them, the abutment platform 30 is provided with multiple first inclined surfaces 31, the base 20 is provided with a receiving groove 22 with an opening facing the radar cover body 10, and multiple side walls of the receiving groove 22 are all inclined surfaces. The abutment platform 30 is inserted into the receiving groove 22, and multiple first inclined surfaces 31 are respectively abutted with different side walls of the receiving groove 22.

[0040] It should be noted that the micro switch is disposed between the base 20 and the radar cover 10 .

[0041] like Fig. 9 As shown, the side walls of the receiving groove 22 are all inclined surfaces, and the inclined surfaces are inclined downward in a direction away from the center of the base 20 .

[0042] like Figure 4As shown, the first inclined surface 31 is inclined downward in a direction away from the center of the abutting platform 30 .

[0043] It can be understood that when the abutment platform 30 is inserted into the receiving groove 22 , one of the first inclined surfaces 31 abuts against a side wall inclined surface of the receiving groove 22 .

[0044] It should be noted that Figure 5 For example, when the radar cover 10 is subjected to a force from right to left, due to the transmission between the first inclined surface 31 and the inclined surface of the side wall of the accommodating groove 22, the radar cover 10 is subjected to a downward force and moves downward, and then contacts the micro switch and triggers the micro switch, thereby realizing mechanical pressure triggering, which is convenient for prompting the mobile robot to move forward and collide.

[0045] It is understandable that Figure 5 For example, when the radar cover 10 is subjected to a force from top to bottom, the radar cover 10 is driven to move in a vertical direction, contact the micro switch, and trigger the micro switch.

[0046] It is understandable that if Figure 6 For example, when the radar cover 10 is subjected to a force perpendicular to the cross-section, due to the presence of multiple pairs of the first inclined surfaces 31 abutting against the inclined side walls of the accommodating groove 22, the radar cover 10 can be subjected to a component force from top to bottom, thereby driving the radar cover 10 to move and triggering the micro switch.

[0047] The technical solution of the present invention is to provide the abutment platform 30 with multiple first inclined surfaces 31 on the side of the radar cover 10, and insert it into the accommodating groove 22 with multiple inclined side walls, so that one of the first inclined surfaces 31 abuts against the inclined side wall of one side of the accommodating groove 22. When the mobile robot moves and the radar cover 10 is subjected to external force from the front side of the movement, top surface pressure or external forces on the left and right sides of the moving direction, the radar cover 10 can be subjected to a component force in the direction close to the base 20 under the transmission of the inclined surface, so that the radar cover 10 is close to the base 20 and the micro switch is triggered to issue a collision prompt, thereby expanding the range of pressure triggering of the radar cover 10 and ensuring the smooth movement of the mobile robot.

[0048] In one embodiment, the plurality of first inclined surfaces face different directions respectively.

[0049] like Figure 4 As shown, the first inclined surfaces are oriented away from the bottom surface of the base 20 and in different directions.

[0050] It can be understood that the first inclined surfaces in multiple different orientations cooperate with the inclined side walls of the accommodating groove 22 in multiple different orientations. When the radar cover 10 is subjected to external forces in different directions, the interaction between the inclined surfaces can generate a component force for the radar cover 10 to move toward the base 20, thereby driving the radar cover 10 to approach the base 20 and triggering the micro switch to generate a collision prompt.

[0051] It can be understood that the provision of multiple first inclined surfaces enables the radar cover 10 to move and trigger the micro switch when responding to external forces in different directions, thereby expanding the pressure triggering range of the radar cover.

[0052] In one embodiment, a mounting groove 23 is disposed in the base 20 . The mounting groove 23 is located on a side of the receiving groove 22 away from the bottom surface of the base 20 , and a bottom wall of the mounting groove 23 is a second inclined surface.

[0053] In order to facilitate the assembly between the radar cover 10 and the base 20 , the mounting groove is provided on the side of the receiving groove 22 away from the bottom surface of the base 20 .

[0054] like Figure 3 to Figure 4 As shown, an arc groove 11 is provided on the radar cover, and the arc groove 11 is provided on one side of the abutment platform 30 .

[0055] It should be noted that the arc center of the arc groove 11 is close to the abutment platform 30 .

[0056] like Fig. 9 As shown, the bottom wall of the mounting groove 23 is a second inclined surface.

[0057] It is understandable that Figure 5 For example, during the installation of the radar cover 10, the abutment platform 30 first extends into the installation groove 23. At this time, when an external force is applied to the radar cover 10 from top to bottom, driven by the second inclined surface, the radar cover 10 on one side of the abutment platform 30 is partially deformed, and the spacing between the groove walls of the arc groove 11 is reduced. As the external force continues to be applied to the radar cover 10, when the abutment platform 30 moves to the side of the receiving groove 22, the deformed part of the radar cover 10 is restored, and the abutment platform 30 extends into the receiving groove 22, thereby completing the assembly between the radar cover 10 and the base 20.

[0058] It can be understood that by providing the mounting groove 23 with the second inclined surface, during the assembly of the radar cover 10, the radar cover 10 only needs to be pressed to achieve quick assembly between the radar cover and the base 20, thereby improving the installation efficiency of the radar cover 10 and reducing material costs.

[0059] It should be noted that in order to avoid displacement between the radar cover 10 and the base 20, a plurality of positioning parts are arranged at intervals on the sides of the radar cover 10, and positioning grooves are arranged on the base 20 corresponding to the positions of the plurality of positioning parts. When the radar cover 10 and the base 20 are assembled, one positioning part is inserted into one positioning groove to achieve positioning restriction of the radar cover 10 and prevent displacement of the radar cover 10.

[0060] In one embodiment, there are multiple abutment platforms 30 , which are spaced apart and distributed on the same side of the radar cover 10 , and are respectively located on both sides of the micro switch corresponding to the position on the radar cover 10 .

[0061] In one embodiment, the base 20 is provided with a plurality of spaced-apart receiving grooves 22 , one abutment platform 30 is inserted into one receiving groove 22 , and one side of one receiving groove 22 facing away from the bottom surface of the base 20 is provided with the installation groove 23 .

[0062] In order to ensure the sensitivity of triggering the micro switch when the radar cover 10 is subjected to external force, a plurality of the abutment platforms 30 and a plurality of the accommodating grooves 22 cooperating with the abutment platforms 30 are provided. When the radar cover 10 is displaced by external force, it can react quickly and trigger the micro switch, thereby improving the timeliness of the collision prompt and ensuring the smooth movement of the mobile robot.

[0063] It can be understood that the multiple abutment platforms 30 are distributed on both sides of the position where the micro switch is projected on the radar cover 10, and the multiple accommodating grooves 22 are distributed on both sides of the micro switch, so that the radar cover 10 can stably output component forces when subjected to external forces in different directions, so that the radar cover 10 triggers the micro switch, ensures the sensitivity of the radar cover 10, and expands the direction range of the external force that triggers the movement of the radar cover 10.

[0064] In one embodiment, a third inclined surface 51 is provided on a side of the base 20 away from the abutting platform 30 , and a side of the radar cover 10 away from the abutting platform 30 abuts against the third inclined surface 51 .

[0065] like Figure 5 and Figure 7 As shown, the portion of the radar cover body away from the abutment platform 30 abuts against the third inclined surface 51. When the radar cover body 10 is subjected to an external force from top to bottom, due to the presence of the third inclined surface 51 and the inclined side wall of the accommodating groove 22, the radar cover body 10 moves toward the lower left, thereby facilitating the stable triggering of the micro switch to generate a collision prompt.

[0066] It can be understood that the setting of the third inclined surface is convenient for supporting the radar cover 10, and also convenient for the radar cover 10 to stably touch the micro switch when subjected to external force from top to bottom, thereby ensuring stable and efficient generation of collision prompts and improving timeliness.

[0067] In one embodiment, a fourth inclined surface 41 is disposed on a side of the radome 10 facing away from the abutting platform 30 , and the fourth inclined surface 41 abuts against the third inclined surface 51 .

[0068] like Figure 7 As shown, the fourth inclined surface 41 abuts against the third inclined surface 51. The abutment between the two inclined surfaces ensures the stability of the support between the radar cover 10 and the base 20, thereby avoiding the instability of transmission due to the small contact area.

[0069] In one embodiment, a first boss 40 is disposed on a side of the radome 10 facing away from the abutting platform 30 , and the fourth inclined surface 41 is disposed on a side of the first boss 40 facing away from the abutting platform 30 .

[0070] like Figure 7 As shown, a first boss 40 is provided on a side of the bottom surface of the radar cover 10 away from the abutment platform 30, and the fourth inclined surface 41 is provided on the first boss 40. Through the setting of the first boss 40, when the fourth inclined surface 41 abuts against the third inclined surface 51, the radar cover 10 can be supported horizontally, so that when the radar cover 10 is acted upon by an external force and is driven to move, it can move accurately in the direction of the micro switch, so as to ensure the accuracy and timeliness of triggering the micro switch.

[0071] In one embodiment, an assembly groove 21 is provided in the base 20, the radar cover 10 is provided in the assembly groove 21, the receiving groove 22 and the installation groove 23 are both provided on the same side wall of the assembly groove 21, and a second boss 50 is provided on the side of the assembly groove 21 away from the receiving groove 22, a fourth inclined surface 41 is provided on the second boss 50, and the first boss 40 abuts against the second boss 50.

[0072] like Figure 2 As shown, the assembly groove 21 is configured to accommodate the radar cover 10 .

[0073] It can be understood that the third inclined surface 51 is arranged on the second boss 50, so that the abutment platform 30 is inserted into the accommodating groove 22, and when the third inclined surface 31 abuts against the inclined side wall of the accommodating groove 22, the mutual abutment between the first boss 40 and the second boss 50 can ensure the smooth assembly of the radar cover 10, so as to facilitate the subsequent displacement of the radar cover 10 when subjected to force.

[0074] It can be understood that the radar cover 10 and the base 20 are assembled smoothly, so that the third inclined surface 31 is completely abutted against the inclined side wall of the accommodating groove 22, which in turn ensures the stability during force transmission and ensures that the radar cover 10 can stably trigger the micro switch when it moves under force, thereby improving the effectiveness and sensitivity of the trigger.

[0075] The utility model also proposes a mobile robot, which includes the radar cover 100. The specific structure of the radar cover 100 refers to the above embodiment. Since the mobile robot adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought by the technical solutions of the above embodiments, which will not be described one by one here.

[0076] The above description is only an exemplary embodiment of the present invention, and does not limit the patent scope of the present invention. All equivalent structural changes made by using the contents of the present invention specification and drawings under the technical concept of the present invention, or directly / indirectly applied in other related technical fields are included in the patent protection scope of the present invention.
