The elastic buckle assembly 1330 of the middle sweeping lid assembly 1300 is simple in structure and convenient to process, disassemble and the like.

Referring to fig. 1 to 2, in one embodiment, the middle-scanning box 1100 includes a fixing plate 1200, the fixing plate 1200 is detachably coupled to the middle-scanning box 1100, and the fixing hole 1210 is disposed on the fixing plate 1200. The fixing plate 1200 is detachable, so that the fixing plate 1200 can be formed separately, and the requirement of higher strength of the fixing plate 1200 relative to the middle-scanning box 1100 can be met.

Referring to fig. 1 to 10, in one embodiment, the number of the fixing holes 1210 of the middle-scan cassette 1100 is plural, and the number of the locking hooks 1332 on the surface of the side of the slide plate 1331 facing away from the toggle 1333 corresponds to the number of the fixing holes 1210.

Referring to fig. 6 to 7, it is achieved that one of the elastic buckle assemblies 1330 is matched with the fixing hole 1210 by the locking hooks 1332 of the slide plate 1331, and when the slide plate 1331 slides, the matching state of all the locking hooks 1332 with the fixing hole 1210 is changed at the same time.

In one embodiment, the second end of the middle-scan cover 1310 is detachably coupled to an opposite-side fixing hole provided on the middle-scan casing 1100 by a second elastic buckle assembly coupled to the second end.

The second elastic buckle assembly includes:

a second base plate coupled to the middle-sweep cover plate 1310;

a second sliding plate disposed between the second base plate and the middle-sweep cover plate 1310;

In this embodiment, the first end of the middle scanning plate 1310 is detachably connected to a fixing hole 1210 provided on the middle scanning box 1100 by an elastic buckle assembly 1330 connected to the first end; the second end of the middle-broom cover 1310 is detachably coupled to an opposite-side fixing hole provided on the middle-broom case 1100 by a second elastic buckle assembly coupled to the second end. The elastic buckle assembly 1330 and the second elastic buckle assembly are firmly fixed together to the center-sweeping cover 1310.

In one embodiment, the second elastic buckle assembly is arranged in a central symmetry with the elastic buckle assembly 1330.

The second elastic buckle assembly is arranged symmetrically with respect to the center of the elastic buckle assembly 1330. The user can simultaneously release the second elastic fastener assembly and the elastic fastener assembly 1330 by using a single-hand pinching operation, and the user can conveniently remove the middle broom cover assembly 1300 from the middle broom box 1100 by using a single hand because the second elastic fastener assembly and the elastic fastener assembly 1330 are located on the symmetry axis of the middle broom cover 1310.

In one embodiment, the side of the toggle piece 1333 adjacent to the resilient piece 1335 has a female chamfer 13331.

Referring to fig. 9 to 10, if the side of the toggle 1333 close to the elastic member 1335 is perpendicular to the slide plate 1331, the process of removing the middle wiper cover assembly 1300 completely depends on friction. The female chamfer 13331 provides an internal buckle structure to facilitate easy finger placement and finger gripping of the toggle 1333 when the user operates the toggle 1333, and the female chamfer 13331 increases the finger contact area of the toggle 1333 and the user, thereby increasing the friction force of the user to facilitate removal of the middle broom cover assembly 1300 from the middle broom box 1100.

In one embodiment, the elastic buckle assembly 1330 includes two locking hooks 1332, two locking hooks 1332 are symmetrically disposed at two sides of the toggle piece 1333, and the sliding hole 1311 is disposed at a middle position of the first end.

Two locking hooks 1332 are disposed on two sides of the toggle piece 1333 in a position-symmetrical manner, and the orientations of the locking hooks 1332 are the same; so as to ensure that when the sliding plate 1331 is pulled, the two locking hooks 1332 can be simultaneously separated from the fixing holes 1210 or simultaneously fixed to the fixing holes 1210.

The toggle piece 1333 is mounted at a middle position of the first end, so that the force applied to the middle wiper cover assembly 1300 is uniform in the process that a user takes off the middle wiper cover assembly 1300 through the toggle piece 1333; while the symmetrical arrangement of the locking hooks 1332 increases the stability of the middle-scan cover assembly 1300 in fixing the middle-scan casing 1100.

In one embodiment, the first end is provided with an internal recess 1312.

Referring to fig. 3, the interior recess 1312 provides a point of application for a user to facilitate the removal and installation process of the middle wiper cover assembly 1300.

In one embodiment, the elastic buckle assembly 1330 includes four locking hooks 1332, and the four locking hooks 1332 are uniformly distributed on one side of the sliding plate 1331.

The increased number of the locking hooks 1332 enhances the stability of the fixing of the middle-scan cover assembly 1300 to the middle-scan casing 1100 without increasing the difficulty of manufacturing and assembling the elastic buckle assembly 1330.

Referring to fig. 7-8, in one embodiment, the locking hook 1332 includes a bent free end away from the sliding plate 1331, and the free end is chamfered at a side near the sliding plate 1331. In the process of matching the locking hook 1332 with the fixing hole 1210, the existence of the chamfer plays a role in guiding, and the matching process is facilitated.

A sweeper comprising the middle sweeping cover assembly 1300. The middle sweeping cover assembly 1300 is simple in structure and stable in fixation.

Referring to fig. 11-15, in an embodiment of the present invention, a sweeper includes a radome assembly, the radome assembly includes:

a radome 2200, wherein the radome 2200 comprises a plate 2210 and a top cover 2220 arranged on the plate 2210, the top cover 2220 is used for covering the radar, and the radome 2200 is connected to a top plate 2300 of the sweeper in a turnover manner by taking a first rotating shaft as an axis;

a first sensing device disposed between the top plate 2300 and the plate 2210 of the sweeper, the first sensing device being electrically connected to a processor of the sweeper, wherein the first sensing device is configured to sense a change in state of the radome 2200.

In this embodiment, the radome 2200 is connected to the top plate 2300 of the sweeper in a reversible manner with the first rotating shaft as the shaft. Two clamping heads 2211 are arranged on the surface of the plate body 2210, which is far away from the top cover 2220, and a supporting part 2212 is arranged between the two clamping heads 2211; the top plate 2300 is provided with a rotating shaft hole 2310 correspondingly matched with the chuck 2211 and a mounting groove corresponding to the support portion 2212, wherein the support portion 2212 is substantially cylindrical and is substantially horizontally mounted in the mounting groove, a plurality of support bars 2320 are convexly arranged in the mounting groove towards the support portion 2212 to support the support portion 2212, in this embodiment, each support bar 2320 extends in the mounting groove along the width direction of the mounting groove, and the support bars 2320 are arranged at intervals along the length direction of the mounting groove; further, in order that the supporting portion 2212 is engaged with the mounting groove to form a fitting structure that does not hinder the turning of the radome 2200, a side of the supporting rib 2320 facing the supporting portion 2212 is preferably configured as an arc surface, and a middle portion of the arc surface is recessed in a direction away from the supporting portion 2212, so that the supporting portion can be uniformly supported by the supporting ribs 2320 and can rotate on the arc surface of the supporting rib 2320 to smoothly and stably turn the radome 2200.

During specific installation, the clamping head 2211 is matched with the rotating shaft hole 2310, so that the radome 2200 is hinged to the top plate 2300, and the radome 2200 can be connected to the top plate 2300 of the sweeper in a turnover manner by taking the first rotating shaft as a shaft; the support portion 2212 may support the radome 2200, thereby reducing the burden on the chuck 2211, and the radome 2200 may be rotated based on the support portion 2212 even if the chuck 2211 is broken and failed.

The first sensing device is arranged between the top plate 2300 and the plate body 2210 of the sweeper; when the sweeper does not hit any object, the radome 2200 is in a natural state, and the first sensing device does not obtain a trigger signal. When the sweeper encounters a collision, the first sensing device senses the state change trend of the radome 2200 and determines that the sweeper collides with an object. The radome 2200 described above tends to change state by tipping up, falling back, or sinking. The collision sensing mechanism of the sweeper is integrated in the radar cover structure, so that the space in the sweeper is fully utilized.

Referring to fig. 12-15, in one embodiment, the radome assembly further comprises a frame 2100 and a second inductive device;

a hollow portion 2110 is arranged in the middle of the frame 2100, the hollow portion 2110 is used for penetrating through a radar of the sweeper, the radome 2200 is fixed on the frame 2100 in a turnover manner by taking a second rotating shaft as an axis, one side of the frame 2100 is connected to a top plate 2300 of the sweeper in a turnover manner by taking the first rotating shaft as an axis, so that the radome 2200 is connected to the top plate 2300 of the sweeper in a turnover manner by taking the first rotating shaft as an axis through the frame 2100, and an included angle of 45 degrees to 135 degrees is formed between the second rotating shaft and the first rotating shaft;

the second sensing device is disposed between the top plate 2300 of the sweeper and the frame 2100 or between the top plate 2300 of the sweeper and the plate 2210, the second sensing device is electrically connected to the processor of the sweeper,

wherein the second sensing device is used for sensing a state change of the frame 2100.

When the sweeper does not hit any object, the radome 2200 is in a natural state, and the first sensing device does not obtain a trigger signal. The state change tendency of the radome 2200 is the largest when the impact force is perpendicular to the first rotation axis, and the state change tendency of the radome 2200 is the smallest when the impact force is parallel to the first rotation axis. The first sensing device senses the state change trend of the radome 2200, so that the sweeper collides with an object. The above-mentioned state change tendency is an upturn or a fall or a sink.

When the sweeper does not hit any object, the radome 2200 and the frame 2100 are in a natural state, and the second sensing device does not obtain a trigger signal. The state change tendency of the radome 2200 and the frame body 2100 is the largest when an impact force is perpendicular to the second rotation axis, and the state change tendency of the radome 2200 and the frame body 2100 is the smallest when an impact force is parallel to the second rotation axis. The collision of the sweeper with an object is determined by the second sensing device sensing the state change trend of the radome 2200 and the frame 2100. The above-mentioned state change tendency is an upturn or a fall or a sink. The first sensing device is arranged on the top plate 2300 of the sweeper or below the plate body 2210; the second sensing device is disposed on the top plate 2300 of the sweeper or under the frame 2100.

In this embodiment, the first rotation axis and the forward direction axis Y of the sweeper form an angle of 15 degrees to 75 degrees, the second rotation axis and the forward direction axis Y of the sweeper form an angle of-15 degrees to-75 degrees, and the second rotation axis is perpendicular to the first rotation axis. The first rotating shaft and the second rotating shaft are respectively positioned on two sides of a forward direction shaft Y of the sweeper, and the angle of the first rotating shaft and the second rotating shaft is set so that at least one of the first sensing device and the second sensing device can obtain stronger signal sensing no matter which direction the sweeper impacts an object.

In one embodiment, the first rotating shaft and the second rotating shaft are perpendicular to each other, so that at least one of the first sensing device and the second sensing device can obtain corresponding sensitive sensing no matter which direction the sweeper impacts an object.

In one embodiment, the first rotating shaft forms an included angle of 45 degrees with a forward direction axis Y of the sweeper; the second rotating shaft and the forward direction axis Y of the sweeper form an included angle of-45 degrees.

The angle between the first rotating shaft and the second rotating shaft is set, so that no matter which direction the sweeper impacts an object, at least one of the first sensing device and the second sensing device can obtain excellent sensing. In this embodiment, the radome 2200 is fixed to the hollow portion 2110 of the frame 2100 in a reversible manner.

Referring to fig. 13, in one case, when an impact force is perpendicular to the first rotation axis, the radome 2200 is turned up with respect to the frame 2100; and at this time, the impact force is parallel to the second rotation axis, and the frame 2100 has the smallest tendency to be flipped up with respect to the top plate 2300.

Referring to fig. 14, in one case, when an impact force is perpendicular to the second rotation axis, the frame body 2100 is turned up with respect to the top plate 2300; and the impact force is parallel to the first rotation axis at this time, the radome 2200 has a minimum tendency to be upturned with respect to the frame body 2100.

Referring to fig. 15, in one instance, when an impact force is applied from the forward direction axis Y of the sweeper, the radome 2200 is flipped up relative to the frame 2100, and the frame 2100 is also flipped up relative to the top plate 2300.

Note that in fig. 13 to 15, the degree of the upturning of the radome 2200 or the frame 2100 is exaggerated. Even in some implementations, the top plate 2300 is covered with a cover that limits the flip-up of the radome 2200 and the frame 2100, but does not limit the sag of the radome 2200 or the frame 2100.

In one embodiment, the first sensing device and the second sensing device are both elastic switches.

When the radome 2200 is in a natural state, the elastic switch of the first sensing device is not triggered. When the radome 2200 is tilted or has a tendency to be tilted, the elastic switch of the first sensing device is still not triggered, and only when the radome 2200 falls back and falls back to form a sinking state beyond an original natural state, the elastic switch of the first sensing device is triggered.

When the radome 2200 and the frame 2100 are in a natural state, the elastic switch of the second sensing device is not triggered. When the radome 2200 is tilted up together with the frame 2100 or has a tendency to be tilted up, the elastic switch of the second sensing device is still not triggered, and only when the radome 2200 falls back together with the frame 2100 and falls back to a state of being sunk beyond an original natural state, the elastic switch of the second sensing device is triggered.

No matter which direction the sweeper impacts an object, at least one of the first sensing device and the second sensing device can obtain corresponding sensing, so that the processor of the sweeper can judge that a collision condition occurs.

In one embodiment, a first elastic member is disposed between the frame 2100 and the top plate 2300 of the sweeper and connected to the bottom of the frame 2100 or the top plate 2300 of the sweeper, wherein the first elastic member is configured to support the frame 2100 and the radome 2200.

In a natural state, the first elastic member supports the whole of the radome 2200 and the frame 2100, so that the gravity of the radome 2200 and the frame 2100 does not completely act on the second sensing device, the possibility of the frame 2100 controlling the second sensing device by mistake is reduced, and the deformed resilience force of the second sensing device can be used for assisting the radome 2200 and the frame 2100 to reset after the second sensing device is pressed and triggered.

In one embodiment, a second elastic member is disposed between the plate body 2210 and the top plate 2300 of the sweeper, and the second elastic member is connected to the bottom of the plate body 2210 or the top plate 2300 of the sweeper, wherein the second elastic member is used for supporting the radome 2200.

In a natural state, the second elastic member supports the radome 2200, so that the gravity of the radome 2200 may not completely act on the first sensing device, thereby reducing the possibility that the radome 2200 may erroneously control the first sensing device, and also assisting the radome 2200 to be reset by using the deformed resilience force of the radome after the first sensing device is pressed and triggered.

In one embodiment, the first sensing device and the second sensing device are pressure sensors.

When the radome 2200 is or has a tendency to tip up, the pressure signal on the first sensing device decreases. And when the radome 2200 sinks, the pressure signal on the first sensing device increases.

When the radome 2200 and the frame 2100 are in a natural state, a pressure signal of the second sensing device is larger. When the radome 2200 is flipped up or has a tendency to flip up with the frame 2100, the pressure signal on the second sensing device decreases. When the radome 2200 sinks together with the frame 2100, the pressure signal on the second sensing device increases.

When the second sensing device is disposed between the top plate 2300 of the sweeper and the frame 2100, the direction from which the impact comes can be roughly determined according to the pressure sensing obtained by the first sensing device and the second sensing device, such as obtaining the corresponding relationship between the magnitude relationship of the pressure sensing signals obtained by the first sensing device and the second sensing device and different impact force directions in advance. Specifically, when the impact force affects the magnitude of the pressure sensing signals obtained by the first sensing device and the second sensing device, the magnitude relationship between the pressure sensing signals obtained by the first sensing device and the second sensing device does not change with the magnitude of the impact force. When the sweeper encounters an impact, the processor of the sweeper can judge the direction from which the impact comes according to the corresponding relation obtained by comparing the pressure signal strength relation obtained by the first sensing device and the second sensing device.

In one embodiment, the top housing 2220 is disposed on one side of the plate 2210 near the first and second rotation axes.

The top cover 2220 is disposed on the plate 2210 near the first rotation axis and the second rotation axis, so that the moment of the radome 2200 relative to the first rotation axis and the second rotation axis is shorter, which is beneficial to the radome 2200 to generate a tendency of turning up around the second rotation axis under the action of inertia.

In one embodiment, the end of the top housing 2220 away from the plate 2210 is a top plate, and the center of gravity of the top plate is located on one side of the top plate near the first and second rotation axes.

The design of the gravity center of the top plate close to the first rotating shaft and the second rotating shaft makes the radome 2200 form a structure with unstable gravity center, so that the moment of the top plate relative to the first rotating shaft and the second rotating shaft is shorter, and the radome 2200 is favorable for generating a tendency of turning up by taking the second rotating shaft as an axis under the action of inertia.

In one embodiment, the first sensing device and the second sensing device are the same sensing device, and the first sensing device and the second sensing device are located below the board 2210.

When the frame 2100 is flipped up, the radome 2200 is also lifted up together. When the sensing device is disposed on the top plate 2300 of the sweeper and located on the plate 2210 at a position away from a corner of the first rotating shaft and the second rotating shaft, the sensing device is touched no matter the radome 2200 assembly falls or sinks after being flipped up by the first rotating shaft or the radome 2200 falls or sinks after being flipped up by the second rotating shaft.

In one embodiment, the first and second sensing devices are located on the plate 2210 under a corner away from the first and second rotation axes, which makes the force applied to the sensing devices during the falling back or sinking process after the radome 2200 is flipped up larger.

In summary, when the toggle piece 1333 is not operated, the elastic piece 1335 acts on the sliding plate 1331 to enable the locking hook 1332 to tightly buckle the fixing hole 1210; when the user pulls the toggle piece 1333, the lock hook 1332 moves away from the mutually fastened position to not fasten the fixing hole 1210; the above structure is arranged, so that the elastic buckle assembly 1330 has a simple structure and is convenient to process and operate.

The above only is the preferred embodiment of the present invention, not limiting the scope of the present invention, all the equivalent structures or equivalent flow changes made by the contents of the specification and the drawings, or directly or indirectly applied to other related technical fields, are included in the same way in the protection scope of the present invention.
