Detailed Description
In order to make the objects, technical solutions and advantages of the present application more apparent, the present application will be further described in detail with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the present application.
The laser radar is a radar system for detecting the position, speed and other characteristic quantities of an object by emitting laser beams, and the working principle of the laser radar is that the emitting system firstly emits emitted laser for detection to a detection area, then a receiving system receives reflected laser reflected from the object in the detection area, the reflected laser is compared with the emitted laser, and relevant information of the object such as parameters of distance, azimuth, height, speed, gesture, even shape and the like can be obtained after processing.
Current lidars include a plurality of housings, each housing assembled to form an interior chamber that houses an internal component. The shells are assembled only through simple threaded fasteners, so that the sealing effect of joints between the shells is poor, and the waterproof and dustproof performance requirements cannot be met.
As shown in fig. 1 to 8, in order to solve the above-mentioned problems, the present embodiment provides a housing sealing structure of a laser radar 10, which can enhance the sealing effect of the laser radar 10 and improve the waterproof and dustproof performance of the laser radar 10.
The case sealing structure in the present embodiment includes a first case 200, a second case 100, and a weather strip 300. The first housing 200 and the second housing 100 may be part of a plurality of housings of the laser radar 10, that is, the laser radar 10 may have three or more housings, two of which are the first housing 200 and the second housing 100, and only a part of the laser radar 10 is sealed after the first housing 200 and the second housing 100 are connected. The lidar 10 may also only include the first housing 200 and the second housing 100, wherein after the first housing 200 is connected with the second housing 100, an internal cavity enclosed by the first housing 200 and the second housing is an internal cavity of the lidar 10, and seams between the two are all seams of the lidar 10.
As shown in fig. 1 and 5, the first housing 200 in the present embodiment has a first engagement edge 210, and the first engagement edge 210 may be a surface wall for connection of an outer peripheral side plate of the first housing 200. The first engagement rim 210 is for connection with the second housing 100. The first engaging edge 210 is formed with a first engaging groove 211 extending along a length direction thereof, and the extending direction of the first engaging groove 211 is the same as the extending direction of the first engaging edge 210, and the extending length of the first engaging groove 211 may be completely arranged on the first engaging edge 210 (i.e., the first engaging groove 211 is arranged at all positions along the length direction of the first engaging edge 210) or may be arranged only on a portion of the first engaging edge 210.
The weather strip 300 has elasticity and is capable of being elastically deformed to some extent when being pressed. The sealing strip 300 is embedded in the first engagement groove 211, and may fill the first engagement groove 211 after being deformed to achieve a sealing effect. The sealing strip 300 in this embodiment may be long or annular. The cross-sectional shape of the first engagement groove 211 perpendicular to the longitudinal direction thereof depends on the actual need, and may be, in particular, a regular semicircle, a half waist (about half of a waist-shaped hole), a rectangle, a half ellipse, or the like. Of course, in one embodiment, the cross-sectional shape of the first engaging groove 211 may be rectangular for convenience of processing, and for convenience of filling the first engaging groove 211 after the sealing strip 300 is deformed, rounded chamfers may be provided on both sides of the bottom of the first engaging groove 211 having a rectangular cross-section, so that the sealing strip 300 is easier to fill the chamfer position of the first engaging groove 211 after being deformed.
The specific structure of the weather strip 300 depends on the structure of the first engaging groove 211. When the first engagement groove 211 is annular, the sealing strip 300 may be annular or elongated. When the sealing strips 300 are in a strip shape, the number of the sealing strips 300 in the first joint groove 211 may be one and arranged in an abutting manner from end to end so as to fill the first joint groove 211. When the sealing strips 300 are in a strip shape, the number of the sealing strips 300 in the first joint groove 211 may be plural, and each sealing strip 300 in the first joint groove 211 is sequentially abutted end to end, so as to fill the first joint groove 211.
The second housing 100 has a second engagement rim 110, and the second engagement rim 110 may be a surface wall for connection of an outer peripheral side plate of the second housing 100. The second engagement rim 110 is for connection with the first housing 200. The second joint margin 110 is configured such that, when connected to the first joint margin 210, the sealing tape 300 is deformed by pressing the sealing tape 300 to fill the gap between the first joint margin 210 and the second joint margin 110.
After the first casing 200 is connected with the second casing 100, the first joint edge 210 is attached to the second joint edge 110, the gap between the first joint edge 210 and the second joint edge 110 is the gap required to be sealed by the whole laser radar 10, and when the sealing strip 300 is pressed and deformed by the first joint edge 210 and the second joint edge 110, the gap between the first casing 200 and the second casing 100 can be completely filled, so that a good sealing effect is achieved. And the volume of the sealing strip 300 can be increased due to the existence of the first engagement groove 211, and the deformation amount is correspondingly increased, so that structural failure caused by exceeding the maximum deformation amount in the deformation process of the sealing strip 300 can be avoided.
In order to make the sealing effect of the whole laser radar 10 better, the whole laser radar 10 only has the first housing 200 and the second housing 100, that is, after the first joint edge 210 is attached to the second joint edge 110, the first housing 200 and the second housing 100 together define an internal cavity of the laser radar 10. The seam between the first joint edge 210 and the second joint edge 110 is all the movable joint seam of the lidar 10, and in this case, in order to form a sealing effect, the first joint edge 210 and the second joint edge 110 are all annular and are arranged around the inner chamber. When the first engagement rim 210 is annular, the first engagement groove 211 may then also be annular and extend around the interior chamber of the lidar 10. That is, the sealing strip 300 may be disposed at all joints of the first and second cases 200 and 100, thereby achieving an optimal sealing effect.
When the first engaging edge 210 of the first case 200 has the first engaging groove 211 thereon, it is possible to provide a sufficient receiving space for the sealing tape 300. However, when the deformation amount of the weather strip 300 is large, a large groove needs to be formed in the first case 200 to accommodate the weather strip 300, and the width dimension of the first engaging edge 210 is generally small (i.e., when the first engaging edge 210 is an edge wall surface on a side wall plate of the first case 200, the thickness of the side wall plate is generally small). At this time, in order to facilitate accommodation of the sealing tape 300, a second engagement groove (not shown) may be provided on the second engagement rim 110 of the second housing 100, the second engagement groove defining a space accommodating the sealing tape 300 together with the first engagement groove 211. The second engagement groove may have substantially the same structural shape as the first engagement groove 211, and will not be described herein.
Of course, when the space volume of the first engagement groove 211 is sufficient to accommodate the weather strip 300, the second engagement rim 110 may be made planar without the second engagement groove disposed thereon. Such a structure can reduce the processing difficulty, save the manufacturing cost, and simultaneously can more highly squeeze the sealing tape 300, thereby deforming the sealing tape 300 to fill the gap of the joint between the first case 200 and the second case 100.
To enhance the sealing effect of the sealing strip 300, in one embodiment, the first engaging edge 210 may have a first outer protruding portion 212, and the second engaging edge 110 may have a first inner recessed portion 111, where the first outer protruding portion 212 is attached to the first inner recessed portion 111. The first joint groove 211 has a first joint section located at the position of the first outer flange 212, the weather strip 300 has a first seal section 310 embedded in the first joint section, the first seal section 310 is in a straight line shape and configured to be deformed by bending after being pressed by the first outer flange 212 (the first seal section 310 may be elastically deformed or slightly plastically deformed when deformed by bending), so as to fill the first joint section. That is, the first engaging groove 211 has at least a portion that is not linear, so that the sealing strip 300 needs to be bent at this portion. And in particular, the portion of the sealing strip 300 received at the above-mentioned bending portion is the first sealing section 310, the initial state of the first sealing section 310 is in a straight line shape, and after the first sealing section 310 is received in the first coupling section, it is subjected to a bending deformation process, for example, as shown in fig. 8, the first sealing section 310 is deformed from the original position a to the original position b. In the bending process of the first sealing section 310, on one hand, the deformation amount can be increased, so as to enhance the sealing effect, on the other hand, the first sealing section 310 can be in closer contact with the first joint edge 210 and the second joint edge 110, so that the sealing strip 300 is positioned at the first sealing section 310 in the process that the sealing strip 300 is extruded and slowly deformed, and the sealing strip 300 is prevented from moving in the first joint groove 211 in the process that the sealing strip 300 is extruded and deformed, so that the deformation amount of the places where the sealing strip 300 is large and the deformation amount of the places where the sealing strip 300 is small are prevented, and the sealing effect of the places where the first joint groove 211 is not uniform.
In order to enhance the sealing effect, a plurality of first outer protrusions 212 may be provided at the first joint margin 210, and a plurality of first inner recesses 111 may be provided at the second joint margin 110, and each of the first outer protrusions 212 is fitted to each of the first inner recesses 111 in a one-to-one correspondence. This enables the weather strip 300 to have multiple bending positions and thus multiple anchor points.
Of course, in order to avoid bending the sealing strip 300 in the same direction everywhere, the first joint edge 210 may further have a second concave portion 213, the second joint edge 110 may further have a second convex portion 112, the second convex portion 112 may be attached to the second concave portion, the first joint groove 211 may have a second joint section located at the position of the second concave portion 213, the sealing strip 300 may have a second seal section 320 embedded in the second joint section, and the second seal section 320 may be linear and configured to be deformed by bending after being pressed by the second convex portion 112 (the second seal section 320 may be elastically deformed or slightly plastically deformed when deformed by bending), thereby filling the second joint section. Such a structure can prevent the portion of the sealing tape 300 near the first joint margin 210 and the portion near the second joint margin 110 from being uniformly deformed, and prevent the phenomenon that one end portion of the sealing tape 300 is excessively compressed and the other opposite end portion is excessively pulled when the sealing tape 300 is bent in a certain direction everywhere.
In another embodiment, when the first engaging edge 210 has the first outer protruding portion 212, the second engaging edge 110 has the first inner recessed portion 111, and the first outer protruding portion 212 is attached to the first inner recessed portion 111, the first engaging groove 211 has a first engaging section located at the position of the first outer protruding portion 212, and the sealing strip 300 has a first sealing section 310 embedded in the first engaging section, in particular, the first sealing section 310 is curved and configured to be deformed after being pressed by the first outer protruding portion 212 so that the bending angle becomes smaller, thereby filling the first engaging section. That is, although the first seal segment 310 is curved, the first seal segment 310 is still curved and deformed during the process of being received in the first joint segment, and the degree of curvature thereof becomes smaller during the process of being curved and deformed. As shown in fig. 7, the first seal segment 310 is deformed from a to b, thereby enabling the first seal segment 310 to be tightly positioned in the first joint segment.
When the first sealing section 310 is a curved section, the structure of the first sealing section 310 is the same as that of the first sealing section 310, and in the bending process of the first sealing section 310, on one hand, the deformation amount can be increased, so as to enhance the sealing effect, and on the other hand, the first sealing section 310 can be more tightly abutted against the first joint edge 210 and the second joint edge 110, so that the sealing strip 300 is positioned at the first sealing section 310 in the process that the sealing strip 300 is extruded and slowly deformed, the sealing strip 300 is prevented from moving in the first joint groove 211 in the process that the sealing strip 300 is extruded and deformed, the deformation amount of the part where the sealing strip 300 is large, the deformation amount of the part where the sealing strip 300 is small, and the sealing effect of the part where the first joint groove 211 is not uniform.
When the first seal segment 310 is curved, similarly, in order to enhance the sealing effect, a plurality of first outer protrusions 212 may be provided at the first joint edge 210, and a plurality of first inner recesses 111 may be provided at the second joint edge 110, and each of the first outer protrusions 212 is in one-to-one correspondence with each of the first inner recesses 111. This enables the weather strip 300 to have multiple bending positions and thus multiple anchor points.
Of course, in order to avoid bending the sealing strip 300 in the same direction everywhere, the first joint edge 210 may further have a second concave portion 213, the second joint edge 110 may further have a second convex portion 112, the second convex portion 112 may be attached to the second concave portion, the first joint groove 211 may have a second joint section located at the position of the second concave portion 213, the sealing strip 300 may have a second seal section 320 embedded in the second joint section, and the second seal section 320 may be bent and configured to be bent and deformed after being pressed by the second convex portion 112, thereby filling the second joint section. Such a structure can prevent the portion of the sealing tape 300 near the first joint margin 210 and the portion near the second joint margin 110 from being uniformly deformed, and prevent the phenomenon that one end portion of the sealing tape 300 is excessively compressed and the other opposite end portion is excessively pulled when the sealing tape 300 is bent in a certain direction everywhere.
The second aspect of the present application also provides a lidar 10, the lidar 10 comprising the housing seal structure in any of the embodiments described above. The lidar 10 may include only the first housing 200 and the second housing 100, and may also include other housings. When the lidar 10 includes other housings and the other housings have a movable joint with the first housing 200 or the second housing 100, the edge positions of the other housings for connection may be provided with a joint groove, and other sealing strips may be provided in the joint groove.
