Description

Technical Field

[0001] The present disclosure relates to the field of intelligent self - moving devices, and particularly to a base station and a self - moving system. Background Art

[0002] Real - time kinematic (RTK) positioning technology is a high - precision positioning method based on the Global Navigation Satellite System (GNSS). Outdoor intelligent self - moving devices can transmit reference signals to the intelligent self - moving devices through an RTK antenna base station. The reference signals contain time signals transmitted by GPS satellites and the position coordinate information of the base station itself. After receiving the reference signals, the intelligent self - moving devices calculate the distance difference from the base station by comparing the time signals transmitted by the satellites and the time information contained in the reference signals, enabling the outdoor intelligent self - moving devices to have the ability to autonomously plan a walking path map with centimeter - level accuracy.

[0003] The RTK antenna base stations installed on outdoor intelligent self - moving devices are generally 1 - 2 m high and mainly consist of an antenna erection device and an RTK antenna module, etc. The RTK antenna base station has strict centimeter - level requirements for the yaw distance after installation. If the yaw distance is greater than 2 cm, the walking path deviation of the outdoor intelligent self - moving device will be relatively large, and the walking path map needs to be re - planned to ensure the normal walking of the intelligent self - moving device. However, when the current RTK antenna base stations are fixed outdoors, they have a high installation height, few rigid contact points, and a small support contact area. Affected by many factors such as external forces, it is easy for the RTK antenna base stations to deviate from the initial position by a large distance, affecting the accuracy of map points.

[0090] Various exemplary embodiments of the present disclosure will now be described in detail with reference to the accompanying drawings. It should be noted that: unless otherwise specifically stated, the relative arrangements of components and steps, numerical expressions and values set forth in these embodiments do not limit the scope of the present disclosure.

[0098] The embodiments of the present disclosure provide a base station, including an antenna module and an antenna erection device. The base station of the present disclosure can be an RTK antenna base station or other base stations, which will not be listed one by one here. The antenna erection device of the present disclosure includes: a central support member and a tripod assembly. The antenna module is installed on the top of the central support member; the tripod assembly includes a slidable member and a plurality of leg members; the slidable member is sleeved on the central support member and is configured to axially slide in cooperation with the central support member; the leg members are hinged to the slidable member so that the leg members can rotate relative to the central support member to a folded state or an open state; wherein, the bottoms of the plurality of leg members and the bottom of the central support member are configured to jointly support on the working surface as support points.

[0099] In the above solution, multiple leg members are hinged to the slidable member, so that the multiple leg members can rotate relative to the central support member and be in a folded state or an open state. In the open state, the bottoms of the multiple leg members and the bottom of the central support member can cooperate to form multiple rigid support points to jointly support on the working surface, thereby providing a more stable support for the antenna module, reducing the influence of external forces and other factors on the yaw distance, ensuring the map positioning accuracy of the outdoor intelligent self-moving device, and improving the user experience.

[0100] For ease of understanding, the following refers to Figures 1 to 10 and, in combination with an embodiment, details the specific structure and working principle of the base station and the self-moving system of the present disclosure.

[0101] An embodiment of the present disclosure provides a base station, as Figure 1 shown. The base station includes an antenna module 10 and an antenna erection device 20. The antenna erection device 20 includes: a central support member 21 and a tripod assembly 22. The antenna module 10 is installed on the top of the central support member 21, and the tripod assembly 22 can be installed at the bottom of the central support member 21. The tripod assembly 22 may include a slidable member 221 and multiple leg members 222. The slidable member 221 is sleeved on the central support member 21 and is configured to be axially slidably engaged with the central support member 21; the top ends of the leg members 222 are hinged to the slidable member 221 so that the leg members 222 can rotate relative to the central support member 21 to a folded state or an open state.

[0102] In one embodiment, as Figure 2 shown, in the folded state, the multiple leg members 222 can rotate relative to the central support member 21 to a position parallel to the central support member 21; as Figure 1 shown, in the open state, the multiple leg members 222 can rotate relative to the central support member 21 to a triangular position with intervals from each other. In the open state, the bottoms of the multiple leg members 222 and the bottom of the central support member 21 are configured to jointly support on the working surface 40 as support points.

[0103] In the above solution, multiple leg members 222 are hinged to the slidable member 221, so that the multiple leg members 222 can rotate relative to the central support member 21 and assume a folded state or an open state. In other words, the tripod assembly 22 can be telescopically extended or retracted radially. In the open state, since the tops of the multiple leg members 222 are connected to the slidable member 221, the bottoms of the multiple leg members 222 and the bottom of the central support member 21 can cooperate with each other through the sliding fit between the slidable member 221 and the central support member 21 to form multiple rigid support points, which jointly support on the working surface 40, thereby enabling more stable support for the antenna module 10, reducing the influence of various factors such as external forces on the yaw distance, ensuring the map positioning accuracy of the outdoor intelligent self-moving device, and improving the user experience.

[0104] Moreover, the rotation angle of the multiple leg members 222 relative to the central support member 21 can be adjusted according to the actual application scenario. The area enclosed by the multiple support points at the bottoms of the multiple leg members 222 is defined as the effective support area, and the radial dimension of the effective support area can increase or decrease as the rotation angle of the multiple leg members 222 relative to the central support member 21 changes.

[0105] In an embodiment of the present disclosure, as Figure 1 shown, the number of the leg members 222 is three. It can be understood that in other embodiments not shown, the number of the leg members 222 is not limited to three, and it can be four, five or more, which will not be listed one by one here.

[0106] In an embodiment of the present disclosure, as Figure 1 shown, the tripod assembly 22 further includes a link member 223. One end of the link member 223 is hinged to the central support member 21, and the other end is configured to be hinged to the leg member 222. In this way, by providing the link member 223 between the central support member 21 and the leg member 222, the support stability of the entire tripod assembly 22 can be improved. In addition, the link member 223 forms a linkage structure among the leg member 222, the central support member 21, and the slidable member 221. That is, since the link member 223 is hinged between the leg member 222 and the central support member 21, when the leg member 222 moves in the opening or folding direction, it will drive the slidable member 221 to move along the central support member 21 in the height direction, thereby driving other leg members 222 to perform the same action, realizing the linkage of all the leg members 222. Specifically, refer to Figure 1, a hinge seat is provided below the central support 21, and the hinge seat is fixed at the lower position of the central support 21. One end of the connecting rod member 223 is hinged on the hinge seat, and the other end is hinged on the leg member 222. This makes the leg member 222 deflect relative to the slidable member 221 at the upper end due to the restriction of the connecting rod member 223 when it is opened outward relative to the central support 21, and drives the slidable member 221 to slide downward along the central support 21 (refer to Figure 1 view direction), and vice versa. The number of connecting rod members 223 is consistent with the number of leg members 222, and they are installed one by one. Since the leg members 222 are all hinged on the central support member 21, when the slidable member 221 slides downward along the central support member 21, all the leg members 222 open outward, which makes the entire tripod assembly 22 form a linkage structure.

[0107] In one embodiment of the present disclosure, if Figure 3 As shown in FIG. 1 , the bottom end of the central support member 21 is configured to be provided with a fixed base 211A, and the fixed base 211A is configured to be provided with a screw connection portion 2110 on the bottom surface to which the fixing member 30 can be screwed. In this way, by screwing the fixing member 30 on the bottom surface of the fixed base 211A, the bottom end of the central support member 21 can be used as a supporting point to be fixed to the working surface 40. It is understandable that the supporting connection method between the bottom end of the central support member 21 and the working surface 40 is not limited to this.

[0108] In one embodiment of the present disclosure, if Figure 4 As shown in FIG. 2 , the top end of at least one leg member 222 among the plurality of leg members 222 is configured as a first connecting end 222A. The slidable member 221 includes: a first clamp body 2210 and a first locking mechanism 2220 . The first clamp body 2210 is constructed to embrace the central support 21; the first locking mechanism 2220 includes two first clamping members 2221 and a first fastener 2222, and the first connection end 222A is constructed to be clamped by the two first clamping members 2221 on both sides in the radial direction; the first fastener 2222 is constructed to pass through the first connection end 222A and the two first clamping members 2221; the first connection end 222A is constructed to be rotatable around the first fastener 2222 to hinge the slidable member 221; the first fastener 2222 is constructed to be switchable between a locked state and a released state. In the locked state, the first fastener 2222 can compress the two first clamping members 2221 to apply a radial clamping force to the first connection end 222A to clamp the first connection end 222A, and at the same time, make the first clamp body 2210 embrace the central support 21.

[0109] ​​​Specifically, the first clamp body 2210 can be constructed as a deformable member, and the two first clamping members 2221 can be integrally formed with the first clamp body 2210. When the first fastener 2222 presses the two first clamping members 2221 to apply a radial clamping force to the first connecting end 222A, the first clamp body 2210 is deformed at the same time to hold the central support member 21 tightly.

[0110] Thus, by constructing the slidable member 221 to include the first clamp body 2210 and the first locking mechanism 2220, when the slidable member 221 slides to a suitable position relative to the central support member 21, the slidable member 221 can be locked by the first locking mechanism 2220. At the same time, the first fastener 2222 passes through the first connecting end 222A and can also act as a pivot shaft to hinge the first connecting end 222A to the slidable member 221.

[0111] In one embodiment of the present disclosure, the first clamp body 2210 may be provided with a first opening S1 in the circumferential direction, and the two first clamping members 2221 are respectively connected to the two sides of the first opening S1.

[0112] In one embodiment of the present disclosure, the first fastener 2222 may be configured as an operable tensioning member that can be operated. Specifically, the first fastener 2222 may include a first screw and a first knob 2222A. Screw holes are provided on the first clamping member 2221 and the first connecting end 222A. The first screw may pass through the screw holes on the first clamping member 2221 and the first connecting end 222A. The first knob is connected to the end of the first screw to facilitate the user to rotate the screw to lock or loosen the first clamping member.

[0113] In one embodiment of the present disclosure, if Figure 4 As shown in FIG. 1 , the top end of at least another leg member 222 among the plurality of leg members 222 is configured as a second connection end 222B. The slidable member 221 further includes a hinge mechanism, wherein the hinge mechanism includes two second clamping members 2241 and a second fastener 2242; the two second clamping members 2241 are connected to the circumference of the first clamp body 2210, and the second connection end 222B is configured to be clamped by the two second clamping members 2241 on both sides in the radial direction; the second fastener 2242 passes through the second connection end 222B and the two second clamping members 2241; the second connection end 222B is configured to be rotatable around the second fastener 2242 to hinge the slidable member 221. In this way, the second fastener 2242 passes through the second connection end 222B, and the second fastener 2242 acts as a pivot axis to hinge the second connection end 222B to the slidable member 221.

[0114] ​​​​​The three leg members 222 are respectively denoted as the first leg member 222, the second leg member 222, and the third leg member 222. Among them, the top end of the first leg member 222 is configured as a first connection end 222A and is hinged to the slidable member 221 through a first locking mechanism 2220; the top end of the second leg member 222 is configured as a second connection end 222B and is hinged to the slidable member 221 through a hinging mechanism; the top end of the third leg member 222 is configured as a second connection end 222B and is hinged to the slidable member 221 through a second locking mechanism.

[0115] In one embodiment, the second fastener 2242 can be configured not to lock the second leg member 222 and the third leg member 222. Since the three leg members 222 are all hinged to the same slidable member 221, when the first leg member 222 rotates relative to the central support member 21, it will drive the slidable member 221 to axially slide. Thus, the second leg member 222 and the third leg member 222 can be linked with the slidable member 221 and accordingly opened or folded. Similarly, when the first leg member 222 is locked by the first locking mechanism 2220, the position of the slidable member 221 relative to the central support member 21 is locked, and the second leg member 222 and the third leg member 222 also cannot rotate relative to the central support member 21. Therefore, only by locking or loosening the first leg member 222, the other two leg members 222 can be locked or loosened simultaneously.

[0116] In another embodiment, the second fastener 2242 is further configured to be able to press two second clamping members 2241 to clamp the second connection end 222B. In this way, the second connection end 222B can be locked or loosened by the first locking mechanism 2220.

[0117] When the RKT antenna base station in this embodiment is in use, operate the first fastener 2222 and the second fastener 2242 to make the first locking mechanism 2220 and the hinging mechanism in a loosened state to loosen the first leg member 222, the second leg member 222, the third leg member 222, and the first clamp body 2210. Slide the first clamp body 2210 axially along the central support member 21, and at the same time rotate the three leg members 222 relative to the central support member 21 until the three leg members 222 are opened to an appropriate angle. At this time, operate the first fastener 2222 to lock the first clamp body 2210 and the first leg member 222, and operate the second fastener 2242 to lock the second leg member 222 and the third leg member 222, so that the tripod assembly 22 and the central support member 21 jointly support on the working surface 40.

[0118] In one embodiment of the present disclosure, the connecting rod member 223 is configured to have a receiving groove on one side facing the leg member 222, and the receiving groove is configured to receive the corresponding leg member 222 when the leg member 222 is in a folded state. In this way, by providing the receiving groove, on the one hand, the corresponding leg member 222 can be received in the folded state to reduce the volume of the entire base station, which is convenient for storage and transportation, and on the other hand, it can increase the strength while reducing the weight.

[0119] In one embodiment of the present disclosure, the central support member 21 includes: a telescopic rod 210 and a locking mechanism 211. The telescopic rod 210 includes at least two rod bodies. Any two adjacent rod bodies can be connected by plugging each other so that the telescopic rod 210 can be axially extended and retracted; the locking mechanism 211 is arranged at the docking position of the adjacent two-stage rod bodies. The locking mechanism 211 is configured to lock or release the corresponding two-stage rod bodies. In this way, by extending and retracting the telescopic rod 210, the installation height of the antenna module 10 can be conveniently adjusted. The telescopic rod 210 can be locked at a suitable telescopic height by the locking mechanism 211.

[0120] In one embodiment of the present disclosure, if Figure 5 and Figure 6 As shown in FIG. 1 , the locking mechanism 211 includes: a second clamp body 2111 and a second locking mechanism 2112. The second clamp body 2111 includes two clamp units connected together, one clamp unit surrounds one of the two adjacent rod bodies, and the other clamp unit surrounds the other of the two adjacent rod bodies. Figure 5 As shown in , the two clamp units are respectively a first clamp unit 2111A and a second clamp unit 2111B connected together. The second locking mechanism 2112 includes two locking units, one clamp unit corresponds to one locking unit.
