Description

Technical Field

[0001] The invention relates to a self-moving equipment positioning technology, and in particular to a base station and a self-moving equipment operating system. Background Art

[0002] GNSS (Global Navigation Satellite System) real-time dynamic measurement technology (RTK) is a real-time dynamic positioning technology based on carrier phase observations. It can provide real-time three-dimensional positioning results of the measuring station in a specified coordinate system. The RTK system is usually composed of a base station and a mobile station. The base station is used to receive satellite signals and calculate correction data, and the mobile station is used to receive satellite signals and correction data from the base station to achieve high-precision positioning of the mobile station. This technology can be applied to the positioning of self-moving devices such as garden robots, and the self-moving device serves as a mobile station.

[0003] In the related technology, it is necessary to set up a base station with RTK in a scene outside the self-moving device to achieve accurate positioning of the self-moving device. Since the base station is usually set up in an outdoor environment, it is easy to be struck by lightning on rainy days, which can easily cause damage to the electrical components inside the base station.

[0004] The solutions in the related technology include: first, the entire exterior of the base station is completely covered with a shell of insulating material and other structures, and the probability of the base station being struck by lightning is reduced by the properties of the insulating material. However, this solution cannot completely avoid lightning strikes, and the base station may still be struck by lightning. On the other hand, since the antenna is wrapped inside the insulating material, the signal receiving ability is weak; second, the base station is set up near the lightning rod, but this will lead to a reduction in the scope of the base station installation scenario, reducing the user's installation freedom, and it cannot completely avoid lightning strikes. The base station may still be struck by lightning and cause damage to electrical components. The above problems need to be solved urgently.

[0091] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0092] The present invention provides a reference station that can be used for positioning a self-moving device such as a garden robot. Figures 1 to 4 The reference station includes a housing 1, a circuit board 2, a heat dissipation component 4 and an external structure 6. The heat dissipation component 4 is a heat conductor and a conductor. The heat dissipation component 4 can be used to transfer heat and conduct current.

[0093] The heat dissipation member 4 is assembled on the housing 1 , and the heat dissipation member 4 conducts the heat inside the housing 1 to the outside.

[0094] The circuit board 2 is arranged inside the housing 1, and the circuit board 2 is electrically connected to the heat dissipation component 4. Here, the electrical connection means that the circuit board 2 and the heat dissipation component 4 can directly or indirectly conduct current.

[0095] The external structure 6 is disposed on the heat dissipation component 4, and the heat dissipation component 4 is electrically connected to the external structure 6. Here, the electrical connection means that the heat dissipation component 4 and the external structure 6 can directly or indirectly conduct current.

[0096] The external structure 6 can be used to connect to an external ground wire.

[0097] This embodiment uses a heat dissipation component 4 that has both thermal and electrical properties. On the one hand, the heat dissipation component 4 is electrically connected to the external structure 6. When installing and using the base station, the user can connect the external structure 6 to the external ground wire to ground the base station. When the base station is struck by lightning, the current is quickly conducted to the ground through the heat dissipation component 4, the external structure 6 and the ground wire, thereby reducing the potential difference inside the base station, avoiding the generation of destructive voltage, and effectively avoiding the risk of lightning damage to the circuit board 2 and other electrical components inside the base station. The problem that the base station may be struck by lightning and cause damage to electrical components in the related art is solved. At the same time, grounding can also protect electrical components such as the circuit board 2 from electrostatic interference and electromagnetic radiation, which can reduce the noise of the circuit board 2, improve its reliability, and prevent accidents caused by short circuits.

[0098] On the other hand, the heat dissipation component 4 conducts heat and can transfer the heat generated by the operation of the inner part of the housing 1, such as the circuit board 2, to the outside, thereby improving the heat dissipation performance of the reference station and preventing the problem of the reference station malfunctioning due to overheating.

[0099] Since the base station can be sold in conjunction with self-mobile equipment, in order to facilitate packaging and transportation and user self-installation, the base station requires a certain degree of portability and needs to be as small as possible. In this embodiment, the heat dissipation component 4 is used for both heat dissipation and conductive grounding, achieving a multi-purpose effect of one structure, so that the base station of the present invention can achieve the heat dissipation function and the lightning protection function while ensuring that the base station has a small size, thereby improving the functional integration level and space utilization of the base station.

[0100] In order to realize the electrical connection between the circuit board 2 and the heat dissipation component 4, in some optional embodiments, please refer to Figures 2 to 5 , the circuit board 2 and the heat dissipation component 4 are electrically connected by setting an internal passage structure 5; the internal passage structure 5 includes a first conductive member 51, a wire 52, and a second conductive member 53 connected in sequence; the first conductive member 51 is arranged on the circuit board 2, and the second conductive member 53 is arranged on the heat dissipation component 4. In this way, when lightning strikes, the overload current on the circuit board 2 can be conducted to the ground through the first conductive member 51, the wire 52, the second conductive member 53, the heat dissipation component 4, and the external structure 6 in sequence.

[0101] like Figure 2 Place Figure 5As shown in , optionally, the first conductive component 51 and the second conductive component 53 can be conductive components such as screws, and the two ends of the wire 52 have forks. The first conductive component 51 can detachably press the fork at one end of the wire 52 onto the circuit board 2, and the second conductive component 53 can detachably press the fork at the other end of the wire 52 onto the heat dissipation component 4. In this way, the installation and disassembly between the circuit board 2, the internal passage structure 5, and the heat dissipation component 4 can be facilitated.

[0102] The internal passage structure 5 may also adopt other structures as long as it can realize the electrical connection between the circuit board 2 and the heat dissipation component 4, which will not be elaborated here.

[0103] In order to realize the electrical connection and detachable connection between the heat dissipation component 4 and the external structure 6, in some optional embodiments, please refer to Figure 1 and Figure 2 The external structure 6 includes an adapter plate 61 and a fastener 62. The fastener 62 locks the adapter plate 61 on the heat dissipation component 4. The adapter plate 61 and the fastener 62 are both conductors. The fastener 62 can be used to connect the external ground wire. In this way, on the one hand, a detachable connection between the external structure 6 and the heat dissipation component 4 is achieved, which is convenient for installation and disassembly. On the other hand, the fastener 62 can be used not only as a fixing part, but also as a conductor and as an external connection point for connecting the ground wire. When the user installs the base station, the fastener 62 can be loosened first, the external ground wire can be connected between the fastener 62 and the adapter plate 61, and then the fastener 62 can be used to press the ground wire. The installation is complete. The installation is convenient and quick, and it is easy for users to get started.

[0104] The fastener 62 can be a structural member such as a screw made of conductive material.

[0105] The heat dissipation member 4 may be made of a conductive material such as metal.

[0106] The circuit board 2 can design its own lightning protection circuit according to actual needs. For example, a varistor 23 can be used as a protection design.

[0107] In order to improve the safety performance of the reference station, the outer surface of the heat dissipation component 4 and / or the adapter plate 61 is covered with an insulating layer. On the one hand, it can prevent the user from being stimulated by the static electricity generated inside the reference station when touching it, thereby improving safety and stability. On the other hand, when the heat dissipation component 4 and / or the adapter plate 61 are made of metal, the insulating layer can prevent the heat dissipation component 4 and / or the adapter plate 61 from oxidizing and rusting, thereby providing a protective function and extending the service life of the reference station.

[0108] It should be noted that the electrical connection structure between the heat dissipation component 4 and / or the adapter plate 61 still remains conductive and is not affected by the insulating layer.

[0109] Optionally, the heat dissipation component 4 and / or the adapter plate 61 may be coated with an insulating layer by surface treatment. As an example, the heat dissipation component 4 and / or the adapter plate 61 may be formed by secondary injection molding, and the heat dissipation component 4 and / or the adapter plate 61 itself is a metal part, and an insulating layer such as a plastic layer or a rubber layer is formed on the outer layer.

[0110] As an optional example, a first conductive hole 42 is formed on a side of the heat dissipation component 4 facing the circuit board 2. The first conductive hole 42 and the second conductive component 53 are detachably installed in the first conductive hole 42, and the hole wall of the first conductive hole 42 is not covered with an insulating layer. A second conductive hole 43 is formed on a side of the heat dissipation component 4 facing the adapter plate 61, and a fixing through hole 611 adapted to the second conductive hole 43 is formed on the adapter plate 61. The fixing member 62 passes through the fixing through hole 611 and can be detachably assembled in the second conductive hole 43, and the hole wall of the second conductive hole 43 is not covered with an insulating layer. In this way, the heat dissipation component 4 and the adapter plate 61 are relatively fixed, and electrical conduction between the two is achieved.

[0111] In order to improve the waterproof performance, the first conductive hole 42 and the second conductive hole 43 are both non-through holes. For example, the first conductive hole 42 and / or the second conductive hole 43 are blind holes.

[0112] Optional, such as Figure 2 As shown in FIG. 6 , the outer edge of the fixing through hole 611 is not covered with an insulating layer so as to be in contact with the second conductive member 53 for electrical conduction.

[0113] In some optional embodiments, such as Figure 2 As shown in , the heat dissipation component 4 is in the shape of a plate, a heat dissipation assembly hole 1111 is opened on the shell 1, and the heat dissipation component 4 covers the heat dissipation assembly hole 1111; one side of the heat dissipation component 4 faces the circuit board 2, and the other side of the heat dissipation component 4 faces the outside. The plate-shaped heat dissipation component 4 can have a similar function to the shell 1, and cooperate with the shell 1 to wrap the circuit board 2 inside to provide protection, while increasing the heat dissipation area of ​​the heat dissipation component 4, the overlapping area of ​​the heat dissipation component 4 and the circuit board 2 side by side is increased, and the area of ​​the heat dissipation component 4 exposed to the outside is also increased, which is beneficial to heat transfer and effectively enhances the heat dissipation effect without increasing the volume of the reference station.

[0114] In order to further improve the heat dissipation performance of the heat dissipation component 4, in some optional embodiments, such as Figure 2 As shown in the figure, a heat dissipation grille 41 is formed on the side of the heat dissipation component 4 facing the outside. The heat dissipation grille 41 can be in the shape of, but not limited to, strips, grids, fins, etc. The heat dissipation grille 41 can effectively increase the surface area of ​​the side of the heat dissipation component 4 facing the outside, that is, increase the area for heat exchange with the outside, and effectively improve the heat dissipation effect.

[0115] Optionally, the heat dissipation component 4 can be arranged side by side with a gap or in contact with the circuit board 2. The heat dissipation component 4 can form a groove on the side facing the circuit board 2, which fits the components on the circuit board 2 that need to dissipate heat. Optionally, resin or the like can be coated between the two for heat conduction.

[0116] Since the base station is usually installed outdoors and needs to cope with thunderstorms, in addition to the lightning protection function, the waterproof performance must also be improved. Therefore, the heat dissipation grille 41 adopts a non-hollow structure, that is, the heat dissipation grille 41 does not have through holes.

[0117] In order to improve the waterproof performance, optionally, the heat dissipation component 4 is sealed and connected to the housing 1. For example, the heat dissipation assembly hole 1111 can be interference-fitted with the heat dissipation component 4.

[0118] like Figure 2 and Figure 5 As shown in , in some optional embodiments, a plurality of buckle holes 44 are formed on the periphery of the heat dissipation component 4, and latch teeth 1112 adapted to the buckle holes 44 are formed on the periphery of the heat dissipation assembly hole 1111, and the latch teeth 1112 are buckled into the buckle holes 44.

[0119] To improve the waterproof performance, Figure 2 and Figure 5 As shown in , optionally, the heat dissipation component 4 has a circle of inserting edges extending from its periphery, the buckle holes 44 are formed on the inserting edges, and the hole walls of the heat dissipation assembly holes 1111 are radially expanded outward to form a circle of slots, such as Figure 5 As shown in , the latch teeth 1112 are formed on the slot wall of the slot, and the insert edge of the heat dissipation member 4 is inserted into the slot of the hole wall of the heat dissipation assembly hole 1111. The insert edge can prevent water from entering the interior of the housing 1. Further, the slot wall can be interference fit with the insert edge.

[0120] In some optional embodiments, please refer to Figure 5 and Figure 6 The housing 1 is provided with an indicator light structure 9. The indicator light structure 9 is used to provide information to the user, such as power on / off, connection status, mode, etc., so that the user can understand the working status of the reference station.

[0121] Since the base station is usually located in an outdoor environment, in order to improve the waterproof performance of the indicator light structure 9, in some optional embodiments, please refer to Figure 5 and Figure 6 The indicator light structure 9 includes a light source 91, a diffusion plate 92 and a light board sealing ring 93. The light source 91 is located inside the housing 1, and the light source 91 is electrically connected to the circuit board 2.

[0122] The diffuser plate 92 is formed with a diffuser portion 921 and a water retaining ring 922 that protrude in the same direction. The water retaining ring 922 surrounds the outer circumference of the diffuser portion 921 .

[0123] The housing 1 is provided with a lamp board slot 104 , and the inner wall of the housing 1 is recessed to form a water retaining slot 105 , which surrounds the outer circumference of the lamp board slot 104 .

[0124] The diffuser 921 is arranged in the lamp board groove 104, the water retaining ring 922 is arranged in the water retaining groove 105, the lamp board sealing ring 93 is arranged in the water retaining groove 105, and the lamp board sealing ring 93 is located between the water retaining ring 922 and the groove wall of the water retaining groove 105 to achieve a sealing function.

[0125] The water retaining ring 922 has a water retaining function and can effectively prevent water from penetrating into the interior of the housing 1 .

[0126] The light source 91 may be, but is not limited to, a structure such as an LED lamp. The diffusion plate 92 has a light diffusion function to make the light more uniform. Optionally, the diffusion plate 92 may be made of transparent polycarbonate and light diffusion powder.

[0127] In order to ensure better signal reception and transmission effects, ensure a good radio transmission path between the base station and the mobile station, and make the operation distance longer, the base station can be elevated by using a pole mechanism 7. In some optional embodiments, please refer to Figures 7 to 13 The reference station further includes a pole mechanism 7 , an external structure 6 is arranged at one end of the pole mechanism 7 , and a wire passage 702 is formed inside the pole mechanism 7 .

[0128] In order to make the appearance of the base station more concise and protect the wires, the external ground wire, the network cable of the base station, etc. can be passed through the wire channel 702.

[0129] As another alternative grounding scheme, in some optional embodiments, the external structure 6 is not directly connected to the ground wire. The pole mechanism 7 is a conductor, the external structure 6 is electrically connected to the pole mechanism 7, and the pole mechanism 7 has a grounding piece at one end away from the external structure 6, and the grounding piece is used to connect to the external ground wire, or the grounding piece directly contacts the ground. The overloaded current on the circuit board 2 passes through the heat dissipation component 4, the external structure 6, the pole mechanism 7, and the grounding piece in sequence before being grounded.

[0130] In this way, the pole mechanism 7 can be used for elevation and as a conductor. When the grounding piece of the pole mechanism 7 directly contacts the ground, the connection of the ground wire can be omitted, and the installation is fast and convenient. When the grounding piece of the pole mechanism 7 is used to connect to the external ground wire, the length requirement of the ground wire can be reduced.

[0131] As an optional example, the tail end of the pole mechanism 7 is a mounting seat 75, and the bottom of the mounting seat is directly in contact with the ground and directly grounded; as another optional example, a fifth locking piece 775 is provided on the pole mechanism 7, and the user can connect the ground wire to the fifth locking piece 775 to achieve grounding. The fifth locking piece 775 can be a screw, etc.

[0132] In order to improve safety, optionally, the outer surface of the pole mechanism 7 is covered with an insulating layer.

[0133] In order to save the packaging and transportation costs of the stand mechanism 7 and facilitate installation by the user, in some optional embodiments, please refer to Figures 7 to 10 The pole mechanism 7 includes a joint piece 72, a mounting seat 75 and at least two connecting rods 73. A transition piece 74 is provided between the connecting rods 73 and the connecting rods 73 for connection. All the connecting rods 73 and all the transition pieces 74 form a rod group as a whole. The connecting rod 73 at the head end of the rod group is detachably connected to the joint piece 72, and the connecting rod 73 at the tail end of the rod group is connected to the mounting seat 75. The pole mechanism 7 is a multi-stage structure to reduce the volume and reduce the packaging and transportation costs.

[0134] In some optional embodiments, the connecting rod 73 and the adapter 74 are connected in a straight line by buckle connection, and the connecting rod 73 at the head end of the rod group and the connector 72 are connected in a straight line by buckle connection. The quick connection function of the vertical pole structure is realized, and when the user installs, the assembly of the pole group can be completed by straight line plugging, which can effectively improve the installation efficiency, simplify the installation steps, and enhance the user's experience.

[0135] It should be noted that the linear snap connection refers to the snap connection that can be achieved without a large relative rotation (e.g., a rotation of more than 180 degrees) between the connecting rod 73 and the connector 72, or between the connecting rod 73 and the adapter 74. Because if the connecting rods 73 and 73, or between the connecting rods 73 and the connector 72 are connected by threaded connection, a large relative rotation angle will occur between the connecting rods 73 and 73, which may cause the wire inside the connecting rod 73 to be entangled, so a linear snap connection is used. The linear snap connection can be a snap with a small rotation, or a completely straight snap without relative rotation.

[0136] All the connecting rods 73 and all the adapters 74 form a rod group as a whole. The connecting rod 73 at the head end of the rod group is linearly snap-connected with the connector 72, and the connecting rod 73 at the tail end of the rod group is connected with the mounting seat 75.

[0137] The connector 72 and the inside of the rod group are connected to form a wire passage 702. The wire passage 702 is used to accommodate wires such as the SMA wire and the external ground wire on the reference station, which can protect the wires and simplify the appearance of the reference station.

[0138] Optionally, the connecting rod 73 may be tubular, and the internal space thereof is a part of the wire passage 702 . The connecting rod 73 may also be in other shapes, as long as there is a passage on the connecting rod 73 as a part of the wire passage 702 .

[0139] Due to packaging and transportation requirements, the multi-section pole structure can reduce packaging volume and reduce transportation costs.

[0140] The number of connecting rods 73 and the number of adapters 74 can be configured according to actual needs. As an optional example, Figure 7 As shown in , the vertical pole structure includes two connecting rods 73 and a transition piece 74, which are respectively a first rod body 731 and a second rod body 732. The two ends of the first rod body 731 are respectively a second connecting end 7311 and a third connecting end 7312, and the two ends of the second rod body 732 are respectively a fourth connecting end 7321 and a fifth connecting end 7322. The first connecting end 721 is formed on the joint piece 72, and the first transition end 741 and the second transition end 742 are formed on the transition piece 74. The first connecting end 721 is linearly buckled with the second connecting end 7311, the third connecting end 7312 is linearly buckled with the first transition end 741, the second transition end 742 is linearly buckled with the fourth connecting end 7321, and the fifth connecting end 7322 is connected to the mounting seat 75.

[0141] Optionally, the mounting seat 75 and the connecting rod 73 at the end of the rod group can be fixedly connected or detachably connected. Figure 7 As shown in the figure, the mounting seat 75 and the connecting rod 73 at the end of the rod group are detachably connected, and the mounting seat 75 and the connecting rod 73 at the end of the rod group are locked by setting a fifth locking member 775. The mounting seat 75 and the connecting rod 73 at the end of the rod group have matching assembly holes corresponding to the fifth locking member 775. The fifth locking member 775 can be, but is not limited to, a locking member such as a screw or a latch.

[0142] The angle between the connecting rods 73 and 73 can be adjusted according to actual needs. As an optional example, Figure 7 As shown in , the connecting rods 73 may be at a right angle to each other, that is, on the same straight line; as another example, as shown in Figure 8 As shown in , the connecting rods 73 may be at right angles to each other.

[0143] The connecting rods 73 may also be at other angles, which can be achieved by changing the shape of the adapter 74. As an optional example, the adapter 74 is formed with a first adapter end 741 and a second adapter end 742, and the angle between the first adapter end 741 and the second adapter end 742 is a right angle.

[0144] Different angles between the connecting rods 73 can be applied to different installation environments. Figure 7 As shown in , the connecting rods 73 and 73 are at right angles, and the entire rod group is in a straight line state, so the reference station can be installed vertically on a flat ground such as a lawn; as another example, Figure 2As shown in , the connecting rods 73 and 73 are at right angles, and the entire rod group is in a bent state. The base station can be installed on a wall or under the eaves. The above is only an example of an installation scenario and can also be applied to other scenarios, which will not be repeated here.

[0145] In some optional embodiments, please refer to Fig. 9 and Fig.10 The structure of the linear snap connection between the connecting rod 73 and the adapter 74, and the structure of the linear snap connection between the connecting rod 73 and the connector 72 at the head end of the rod group are both snap structures 701. The snap structure 701 includes a snap part 7011 and a snap seat part 7012, and the snap part 7011 and the snap seat part 7012 are linearly elastically snapped. One of the connecting rod 73 and the adapter 74 connected thereto is provided with the snap part 7011, and the other is correspondingly provided with the snap seat part 7012. One of the connecting rod 73 and the connector 72 at the head end of the rod group is provided with the snap part 7011, and the other is correspondingly provided with the snap seat part 7012.

[0146] For example, Figure 7 and Fig. 9 As shown in the figure, one of the connecting rods 73 is a first rod body 731, and the two ends of the first rod body are a second connecting end 7311 and a third connecting end 7312. The joint member 72 has a first connecting end 721, and the first connecting end 721 is provided with a snap-on portion 7011, and the second connecting end is provided with a snap-on seat portion 7012.

The buckle seat part 7012 includes a second pipe section 70121, the second pipe section 70121 is provided with a second clamping hole 70122, the second pipe section 70121 is sleeved on the outer circumference of the first pipe section 70113, and the marble 70112 can be buckled into the second clamping hole 70122.

[0149] For example, one end of the connector 72 connected to the connecting rod 73 is the first connecting end 721. When a spring-loaded portion 7011 is provided on the connector 72, the first connecting end 721 serves as the first tube segment 70113 of the spring-loaded portion 7011. When a buckle seat portion 7012 is provided on the connecting rod 73, the second connecting end 7311 of the first rod body 731 serves as the second tube segment 70121 of the buckle seat portion 7012.

[0150] The elastic member 70111 may be, but is not limited to, an elastic member such as a torsion spring, an elastic pressing sheet, or the like. For example, the elastic member 70111 is a torsion spring, such as Figures 10 to 12 As shown in the figure, the torsion spring is U-shaped, and a marble 70112 is set at one end of the torsion spring. The marble 70112 can be but not limited to a hemispherical, bullet-shaped or cylindrical shape.

[0153] The adapter 74 is provided with three adapter ends in different directions, which can facilitate the user to adjust the angle between the connecting rods 73 and the connecting rods 73 according to their own needs, so as to adapt to more installation environments. For example, there are two connecting rods 73 and one adapter 74. Under this configuration, two installation angles can be achieved between the two connecting rods 73.

[0154] In some optional embodiments, such as Figure 7 and Figure 8 As shown in , the pole structure also includes a cap 76, which is used to perform a linear snap connection at any of the first transfer end 741, the second transfer end 742 and the third transfer end 743. The transfer member 74 is provided with three transfer ends in different directions. When a transfer end is not involved in the connection, it can be buckled with the cap 76, which can be used for dust and water prevention.

[0157] In some optional embodiments, such as Figure 8 As shown in FIG. 7 , a sixth connecting end 751 and a bottom plate 752 are formed at both ends of the mounting seat 75 .

[0158] The sixth connection end 751 is connected to the connection rod 73 at the rear end of the rod group.

[0160] In some optional embodiments, the adapter plate 61 is disposed on one side of the connector 72 , and a second locking member 772 is disposed between the adapter plate 61 and the connector 72 for locking.

[0161] Optionally, in order to improve the stability of the vertical pole structure, a fixed connection scheme other than the spring-lock structure 701 may be provided on the vertical pole structure as an alternative connection scheme.

[0162] For example, Fig. 9 As shown in the figure, in addition to the snap-fastener portion 7011 and the snap-fastener portion 7012, the connector 72 and the connecting rod 73 may also be provided with a third locking member 773. The connector 72 and the connecting rod 73 are provided with corresponding assembly holes.

This solution allows users to choose whether to install or not, and has a high degree of freedom. The fourth locking member 774 can be a screw or a latch.

[0164] In some optional embodiments, the heat dissipation component 4 is located on the side of the adapter plate 61 away from the connector 72, and the heat dissipation component 4 and the adapter plate 61 are locked by setting a first locking member 771, and the first locking member 771 can be a screw or other components. Optionally, the first locking member 771 can be a fastening member 62.

[0165] Please refer to Figures 14 to 17 In some optional embodiments, the housing 1 includes a housing 11 and a cover 12. The cover 12 extends in the vertical direction. The housing 11 includes a first vertical wall 111 and a guide wall 112, the first vertical wall 111 is parallel to the cover 12, the size of the first vertical wall 111 in the vertical direction is smaller than the cover 12, and the size of the first vertical wall 111 in the left-right direction is smaller than the cover 12. The outer edge of the first vertical wall 111 extends toward the outer edge of the cover 12 to form the guide wall 112. The housing 1 of this embodiment can be used to quickly divert water flow to prevent water accumulation at the reference station.

[0166] Optionally, the heat dissipation component 4 is disposed on the housing 11 . For example, the heat dissipation component 4 is disposed on the first vertical wall 111 , a heat dissipation assembly hole 1111 is opened on the first vertical wall 111 , and the heat dissipation component 4 covers the heat dissipation assembly hole 1111 .

[0167] Optionally, the diffusion plate 92 of the indicator light structure 9 is disposed on the cover body 12 .

[0168] This embodiment uses a guide wall 112 to guide the water flow, and concentrates the water to the first vertical wall 111. Under the action of gravity, the water drips downward along the first vertical wall 111 and the cover body 12, thereby realizing the function of rapid diversion, which can effectively prevent water accumulation in the outer shell structure, avoid the situation where water slowly seeps into the outer shell 1 through the gaps due to long-term existence of water accumulation, and optimize the waterproof performance of the base station.

[0169] When the user actually installs the base station, it may not be possible to ensure that the housing 1 is installed completely vertically, and there may be a certain angle deviation. In this case, the guide wall 112 can still guide the water flow and concentrate the water to the first vertical wall 111 to achieve rapid diversion.

[0170] The guide wall 112 gradually converges toward the first vertical wall 111 , and may be gradually converged by an arc-shaped curved surface, or may be gradually converged by an inclined plane, or a combination of the above two, etc.

[0171] In order to provide a guide wall 112 structure with a better drainage effect, in some optional embodiments, please refer to Fig.14 and Fig.15 The guide wall 112 includes a top guide wall 1121, a first side guide wall 1122, a bottom guide wall 1124 and a second side guide wall 1123 which are sequentially connected in an annular manner.

[0172] The lower edge of the top guide wall 1121 is connected to the upper edge of the first vertical wall 111, and the top guide wall 1121 gradually slopes toward the upper edge of the cover body 12. The top guide wall 1121 can quickly drain the accumulated water on the top downward to prevent the water from accumulating on the top.

[0173] The right edge of the first side guide wall 1122 is connected to the left edge of the first vertical wall 111, and the first side guide wall 1122 gradually slopes toward the left edge of the cover body 12. The first side guide wall 1122 can concentrate the water flow to the first vertical wall 111 or the left edge of the cover body 12 to achieve rapid diversion.

[0174] The left edge of the second side guide wall 1123 is connected to the right edge of the first vertical wall 111, and the second side guide wall 1123 gradually slopes toward the right edge of the cover body 12. The second side guide wall 1123 can concentrate the water flow to the first vertical wall 111 or the right edge of the cover body 12 to achieve rapid diversion. The bottom guide wall 1124 is connected to the first vertical wall 111.

[0175] Optionally, the top guide wall 1121 includes a second end face 11212, a first end face 11211, and a third end face 11213 connected in sequence from left to right. The first end face 11211 gradually tilts backward from top to bottom. The second end face 11212 gradually tilts backward from top to bottom, and the second end face 11212 gradually tilts upward from left to right. The third end face 11213 gradually tilts backward from top to bottom, and the third end face 11213 gradually tilts downward from left to right. The second end face 11212, the first end face 11211, and the third end face 11213 are used to centrally guide the accumulated water on the top of the shell 11 to the first vertical wall 111.

[0176] In some optional embodiments, the guide wall 112 further includes a first longitudinal wall 1125 and a second longitudinal wall 1126. The first longitudinal wall 1125 and the second longitudinal wall 1126 are arranged along the vertical direction.

[0177] The left edge of the first side guide wall 1122 extends toward the left edge of the cover body 12 to form a first longitudinal wall 1125 .

[0178] The right edge of the second side guide wall 1123 extends toward the right edge of the cover body 12 to form a second longitudinal wall 1126 .

[0179] The top of the first longitudinal wall 1125 extends toward the upper right to form a seventh end surface 11251, which is connected to the second end surface 11212. The seventh end surface 11251 is used to guide water flow to the first longitudinal wall 1125 and then flow downward along the first longitudinal wall 1125 to quickly drain water.

[0180] The top of the second longitudinal wall 1126 extends upward to the left to form an eighth end surface 11262, and the eighth end surface 11262 is connected to the third end surface 11213. The eighth end surface 11262 is used to guide the water flow to the second longitudinal wall 1126 and then flow downward along the second longitudinal wall 1126 to quickly drain the water.

[0181] A first cut corner 124 is formed at the top left end of the cover body 12, and a second cut corner 125 is formed at the top right end of the cover body 12. The first cut corner 124 is aligned with the front edge of the seventh end surface 11251, and the second cut corner 125 is aligned with the front edge of the eighth end surface 11262.

[0182] In some optional embodiments, such as Fig.15 As shown in the figure, the bottom guide wall 1124 includes a fifth end face 11242, a fourth end face 11241 and a sixth end face 11243 which are connected in sequence from left to right. The fourth end face 11241 is connected to the lower edge of the first vertical wall 111. The fifth end face 11242 is gradually inclined downward from left to right. The sixth end face 11243 is gradually inclined upward from left to right.

[0183] A third cut corner 126 is formed at the left bottom end of the cover body 12 , and a fourth cut corner 127 is formed at the right bottom end of the cover body 12 . The third cut corner 126 is aligned with the front edge of the fifth end face 11242 , and the fourth cut corner 127 is aligned with the front edge of the sixth end face 11243 .

[0184] The fifth end surface 11242 and the sixth end surface 11243 are used to guide the water flow on both sides of the shell 11 to the fourth end surface 11241 to concentrate the water flow and make the water drip downward along the fourth end surface 11241.

[0185] In order to facilitate installation by the user, the first longitudinal wall 1125 and the second longitudinal wall 1126 are recessed toward the inside of the housing 11 to form a recessed portion 15. The recessed portion 15 can be used as a force application point for the user to hold by hand or with a tool.

[0186] In order to minimize the volume of the housing structure while meeting the assembly space required by the internal components, in some optional embodiments, please refer to Fig.14 and Fig.16 The guide wall 112 is convexly formed with a first accommodating cavity wall 131, which smoothly transitions with the guide wall 112. A first accommodating cavity 101 is formed inside the first accommodating cavity wall 131. The first accommodating cavity 101 is used to accommodate and install the antenna 3. The design of the smooth transition between the first accommodating cavity wall 131 and the guide wall 112 is conducive to flow diversion.

[0187] The number of cavity walls can be set according to the number of antennas required by the data center module. As an optional example, the number of cavity walls is three, such as Figures 14 to 16 As shown in the figure, a first accommodating cavity wall 131, a second accommodating cavity wall 132 and a third accommodating cavity wall 133 are convexly formed on the guide wall 112, the first accommodating cavity wall 131 is located at the top of the guide wall 112, the second accommodating cavity wall 132 is located on the left side of the guide wall 112, and the third accommodating cavity wall 133 is located on the right side of the guide wall 112, a first accommodating cavity 101 is formed inside the first accommodating cavity wall 131, a second accommodating cavity 102 is formed inside the second accommodating cavity wall 132, and a third accommodating cavity 103 is formed inside the third accommodating cavity wall 133, and the first accommodating cavity 101, the second accommodating cavity 102 and the third accommodating cavity wall 133 are all equipped with antennas 3.

[0188] The design of the first accommodating cavity wall 131 can be various. In order to improve the guiding effect of the water flow, in some optional embodiments, such as Fig.14As shown in the figure, the first accommodating cavity wall 131 includes a first curved side wall 1311 and a first top wall 1312. The first curved side wall 1311 extends in an arc shape in the horizontal direction, and the first top wall 1312 is arranged on the top of the first curved side wall 1311. The first top wall 1312 and the first curved side wall 1311 surround to form the first accommodating cavity 101. The first top wall 1312 gradually tilts downward from the front to the back. The first curved side wall 1311 can concentrate the water flow to the middle position of the arc to achieve rapid diversion. The inclined design of the first top wall 1312 can also concentrate the water flow to the middle position of the arc of the first curved side wall 1311.

[0189] In some optional embodiments, such as Figures 14 to 16 As shown in , the second accommodating cavity wall 132 includes a second arcuate side wall 1321, which is formed on the first side guide wall 1122, and extends in an arc shape along the vertical direction. The left side of the second arcuate side wall 1321 is connected to the first longitudinal wall 1125, and a part of the first longitudinal wall 1125 can also be regarded as a part of the second accommodating cavity wall 132. The second arcuate side wall 1321 increases the installation space of the antenna 3, and does not cause water accumulation in the housing.

[0190] In some optional embodiments, such as Figures 14 to 16 As shown in , the third accommodating cavity wall 133 includes a third arcuate side wall 1331, which is formed on the second side guide wall 1123, extends in an arc shape along the vertical direction, and is connected to the second longitudinal wall 1126 on the right side of the third arcuate side wall 1331, and a part of the second longitudinal wall 1126 can also be regarded as a part of the third accommodating cavity wall 133. The third arcuate side wall 1331 increases the installation space of the antenna 3, and does not cause water accumulation in the housing.

[0191] In some optional embodiments, such as Fig.15 As shown in , the cover body 12 includes a second vertical wall 121, the second vertical wall 121 extends toward the left edge of the shell body 11 to form a ninth end face 122, and the second vertical wall 121 extends toward the right edge of the shell body 11 to form a tenth end face 123. The ninth end face 122 gradually tilts forward from left to right. The tenth end face 123 gradually tilts backward from left to right. The ninth end face 122 and the tenth end face 123 are used to guide water to the horizontal edges of the cover body 12 and drip quickly along the edges.

[0192] In some optional embodiments, such as Fig.16 and Fig.17 As shown in , a first sealing ring 141 is provided between the housing 11 and the cover 12 for sealing to improve the waterproof performance of the housing structure. Fig.17As shown in the figure, the outer edge of the shell 11 is set as a male buckle, the outer edge of the cover body 12 is set as a female buckle, the male buckle is buckled into the female buckle, and the first sealing ring 141 is squeezed between the male buckle and the female buckle to improve the airtightness.

[0193] In some optional embodiments, such as Fig.14 As shown in , the housing 11 and the cover 12 can be relatively fixed by screws and other parts. The housing 11 is provided with a screw hole, and the hole wall of the screw hole is an inclined hole wall 114, which is inclined downward to prevent water from penetrating into the interior of the reference station through the screw hole.

[0194] In some optional embodiments, the reference station includes at least one antenna 3, and the housing 1 is formed with a corresponding number of accommodating cavities 10 for the antennas 3. The antennas 3 are arranged in the accommodating cavities 10 and extend through the housing 1 to the outside.

[0195] For example, the base station includes three antennas 3, and a first accommodating cavity 101, a second accommodating cavity 102 and a third accommodating cavity 103 are formed on the shell 1. The three antennas 3 are respectively installed in the first accommodating cavity 101, the second accommodating cavity 102 and the third accommodating cavity 103 and protrude through the shell 1 to the outside.

[0196] In order to improve the signal strength, the applicant exposes the antenna 3 to the environment. However, in the outdoor environment, the antenna 3 is easily dislocated under the impact of external forces such as snow, hail, etc., which affects the normal operation of the base station. In order to solve the above problem, in some optional embodiments, please refer to Figures 18 to 23 The housing 1 is provided with a mounting wall 113, and the antenna 3 is disposed on the mounting wall 113. A limiting member 17 is disposed in the accommodating cavity 10, and the limiting member 17 circumferentially limits the antenna 3. A pressing member 18 is detachably disposed in the accommodating cavity 10, and the mounting wall 113 and the pressing member 18 cooperate to limit the antenna 3 axially.

[0197] This embodiment uses a limiter 17 to limit the antenna 3 circumferentially, effectively preventing the antenna 3 from circumferentially rotating. At the same time, a clamping member 18 and a mounting wall 113 are used to cooperate with each other to limit the antenna axially, effectively preventing the antenna 3 from axially moving in a straight line. The cooperation between the circumferential limit and the axial limit can effectively prevent the antenna 3 from being dislocated under the action of external force, thereby improving the overall installation stability and reliability, thereby extending the service life of the base station and effectively coping with the problem of relatively uncontrollable external force influences in outdoor environments.

[0198] Optionally, the mounting wall 113 may be a first longitudinal wall 1125 .

[0199] The limiting member 17 can limit the antenna 3 circumferentially in various ways, as long as the antenna 3 is prevented from rotating circumferentially.

[0200] Optionally, in order to facilitate assembly and disassembly, the limiter 17 can be detachably mounted on the housing 11. For example, a structure with a limiter function or a clamping function is provided on the housing 11, and the limiter 17 is detachably mounted on the housing 11.

[0201] In some optional embodiments, such as Fig.18 and Fig.19 As shown, the limiting member 17 is provided with a circumferential limiting groove 172, which is a non-circular groove. The antenna 3 is radially convex to form a first enlarged portion 32, the shape of which matches the shape of the circumferential limiting groove 172, and the groove wall of the circumferential limiting groove 172 limits the circumferential rotation of the first enlarged portion 32.

[0202] Since the circumferential limit groove 172 of the limit member 17 is a non-circular groove, when the antenna 3 has a tendency to rotate circumferentially, the side wall of the first enlarged portion 32 will press against the groove wall of the circumferential limit groove 172. The groove wall of the circumferential limit groove 172 prevents the antenna 3 from rotating, thereby realizing the circumferential limit function. The structure is simple and easy to assemble, which can effectively prevent the antenna 3 from rotating under the action of external force and prevent the cable from bending and twisting.

[0203] As an example, the first enlarged portion 32 may be a polygonal column, such as Fig.19 The circumferential limit groove 172 is adapted to the shape of the groove-shaped polygonal prism, and the side wall of the prism groove prevents the first enlarged portion 32 from rotating, thereby preventing the antenna 3 from rotating. By adopting the solution of the polygonal prism, the area of ​​the groove wall of the circumferential limit groove 172 against the first enlarged portion 32 can be increased to ensure the limiting effect.

[0204] Optionally, in order to facilitate the assembly personnel to insert the first expanded portion 32 into the limiting member 17, the circumferential limiting groove 172 of the limiting member 17 is a notched groove, that is, the groove wall of the circumferential limiting groove 172 is partially missing, which can be seen in FIG. Fig.18 The shape of the notch groove can facilitate assembly or disassembly. During installation, the stopper 17 is first installed on the housing 11, the antenna 3 is inserted into the installation wall 113, and then the first expanded portion 32 is inserted into the circumferential stopper groove 172 from the notch of the stopper 17.

[0205] Optional, such as Fig.18 As shown in the figure, in order to facilitate assembly, both ends of the notch of the limit member 17 are set as inclined guide end faces 173. From the notch to the inside of the circumferential limit groove 172, the two guide end faces 173 gradually tilt toward each other to expand the area of ​​the first enlarged portion 32 entering the notch, increase the tolerance, and facilitate assembly by assemblers without the need for precise alignment, so that the first enlarged portion 32 can be smoothly inserted during assembly.

[0206] Optional, such as Fig.18As shown in FIG, when the first enlarged portion 32 is a hexagonal prism, two parallel edges of the circumferential limiting groove 172 are perpendicular to the notch to facilitate assembly.

[0207] In some optional embodiments, please refer to Figures 19 to 21 One end of the pressing member 18 is a pressing portion 181, which presses the first enlarged portion 32 toward the mounting wall 113 to axially position the first enlarged portion 32, and the first enlarged portion 32 is located between the pressing portion 181 and the mounting wall 113. In this way, the antenna 3 can be axially positioned to prevent the antenna 3 from axially moving linearly, thereby achieving an anti-drop function.

[0208] As an example, please refer to Figures 19 to 21 The first enlarged portion 32 can be a polygonal column, the side of the first enlarged portion 32 close to the mounting wall 113 is a first abutting top surface 321, and the side away from the mounting wall 113 is a second abutting top surface 322. The clamping portion 181 of the clamping member 18 presses against the second abutting top surface 322 to clamp the first enlarged portion 32 between the mounting wall 113 and the clamping portion 181.

[0209] In some optional embodiments, the first abutting end surface 321 of the first expanded portion 32 may press against the mounting wall 113 . Optionally, in order to improve the sealing and waterproofing effect, a sealing structure may be provided between the first abutting end surface 321 and the mounting wall 113 .

[0210] For example, Fig.19 As shown in , a mounting through hole 1131 is provided on the mounting wall 113, and one end of the antenna 3 is inserted into the mounting through hole 1131. The first bulged portion 32 cannot pass through the mounting through hole 1131. A third sealing ring 142 is sleeved on the antenna 3, and the third sealing ring 142 is located between the first bulged portion 32 and the mounting wall 113. The third sealing ring 142 is used to seal the gap between the antenna 3 and the wall of the mounting through hole 1131.

[0211] In order to facilitate assembly and disassembly, the pressing member 18 is detachably arranged on the housing 11. As a reference solution, a structure with a limit function or a clamping function can be arranged on the housing 11; as another reference solution, additional parts can be arranged on the pressing member 18 to detachably connect the pressing member 18 to the housing 11.

[0212] For examples, please refer to Fig.18 and Fig.19 A sixth locking member 19 is also provided in the housing 1, and a locking structure 119 is formed on the shell 11. The sixth locking member 19 is detachably connected to the locking structure 119. A fastening portion 182 is formed on the pressing member 18, and the sixth locking member 19 positions the fastening portion 182 on the locking structure 119.

[0213] Optionally, the sixth locking member 19 is threadedly connected to the locking structure 119. For example, the sixth locking member 19 is a screw, and the locking structure 119 includes a threaded column 1191, and the thread of the threaded column 1191 is an internal thread. After the pressing member 18 is assembled, the sixth locking member 19 can be screwed on the threaded column 1191 together with the fixing portion 182.

[0214] Alternatively, the sixth locking member 19 may be a latch pin, and the locking structure 119 may be a latch pin seat adapted to the latch pin.

[0215] In some optional embodiments, in order to increase the strength of the thread groove column 1191 and prevent the thread groove column 1191 from breaking, the locking structure 119 further includes a plurality of reinforcing ribs 1192. The accommodating cavity 10 protrudes to form the reinforcing ribs 1192, and one end of the reinforcing ribs 1192 is connected to the locking structure 119. Optionally, the other end of the reinforcing ribs 1192 extends to connect with the clamping structure 117.

[0216] Optionally, to facilitate processing and simplify component structure, such as Fig.18 As shown in , the pressing member 18 can be a bent member, and the two ends of the pressing member 18 are respectively a fixing portion 182 and a pressing portion 181, and a first angle is formed between the fixing portion 182 and the pressing portion 181, and the first angle is one of an acute angle, a right angle and an obtuse angle. The pressing member 18 can be in a sheet shape.

[0217] For example, the fixing portion 182 and the pressing portion 181 form a first angle, which is a right angle. The mounting wall 113, the stopper 17 and the pressing portion 181 are arranged side by side, and the fixing portion 182 abuts against the top end surface of the clamping structure 117 and the top end surface of the locking structure 119. The pressing portion 181 can prevent the antenna 3 from moving in the z-axis ( Fig.21 ) direction.

[0218] In some optional embodiments, a housing 11 is formed with a housing cavity 10, and the antenna 3 is located in the housing cavity 10. A clamping structure 117 is formed in the housing cavity 10, and the clamping structure 117 separates the housing cavity 10 into a first slot body 10a, and the stopper 17, the first expanded portion 32 and the pressing portion 181 are all located in the first slot body 10a.

[0219] The holding structure 117 is wall-shaped, and the limiting member 17, the first expanded portion 32, the pressing portion 181 and the holding structure 117 are arranged side by side and pressed in sequence.

[0220] In order to facilitate assembly, a first avoidance groove 1171 may be provided on the clamping structure, and the first avoidance groove 1171 allows the antenna 3 to pass axially.

[0221] The clamping structure 117 is used not only as a limiting end for axial limiting, but also as a positioning end for the fastening portion 182 of the pressing member 18 .

[0222] Optionally, the holding structure 117 divides the accommodating cavity 10 into a first slot body 10a and a second slot body 10b, and one end of the antenna 3 is an exposed section 31, which is exposed to the outside through the mounting through hole 1131. The first bulged portion 32 is located in the first slot body 10a, and the other end of the antenna 3 away from the exposed section 31 is located in the second slot body 10b.

[0223] In some optional embodiments, please refer to Fig.18 and Fig.21 In order to facilitate the installation of the limiter 17 on the housing 11, a buckling portion 118 is formed in the accommodating cavity 10. The limiter 17 is provided with a first buckling groove 171, and the buckling portion 118 is buckled into the first buckling groove 171. The buckling portion 118 holds the limiter 17 in the y-axis ( Fig.21 ) direction on the housing 11 to prevent the limit member 17 from moving relative to the housing 11 in the y-axis direction.

[0224] Optionally, the pressing portion 181 is provided with a second buckle groove 184, and the buckle portion 118 is buckled into the second buckle groove 184. In this way, the buckle portion 118 holds the pressing portion 181 in the y-axis ( Fig.21 ) direction on the housing 11 to prevent the pressing member 18 from moving relative to the housing 11 in the y-axis direction.

[0225] In some optional embodiments, the antenna 3 is radially outwardly convex to form a second enlarged portion 33 , the second enlarged portion 33 is smaller than the first enlarged portion 32 , and the first enlarged portion 32 is located between the second enlarged portion 33 and the mounting wall 113 .

[0229] The base station in the related art adopts the commonly used power grid power supply method and is connected using a standard power cord. The applicant proposed a solution to apply a new power supply method, using PoE (Power over Ethernet). PoE power supply uses network cables for power supply, but because the base station is often set up outdoors and needs to be used in rainy, snowy and other environments, the commonly used network cable interface does not have a waterproof function and is not suitable for direct application on the base station.

[0230] To solve the above problem, in some optional embodiments, the housing 1 has a mounting end surface 115 , and a first through hole 1151 is formed on the mounting end surface 115 . The first through hole 1151 extends toward the outside of the housing 1 to form a connecting ring 1132 .

[0233] A network cable channel is reserved inside the waterproof connector assembly 8 for holding an external network cable, and two ends of the network cable channel are connected to the outside world and the network cable interface 21 respectively.

[0234] The present embodiment adopts a scheme of sealing connection between the waterproof connector assembly 8 and the connecting ring 1132. The connecting ring 1132 has a water-blocking function to prevent water from contacting and affecting the network cable interface 21 and the electrical components in the base station. The waterproof connector assembly 8 is used to clamp the network cable connected to the network cable interface 21, and has the functions of positioning the network cable and waterproofing. The interface structure of the base station in the present embodiment has a wider range of applications and can be used in outdoor environments. It can effectively prevent the base station from being unable to work normally due to rainwater, snow water, etc. penetrating into the base station.

[0235] It should be noted that the sealing connection can be a static seal or a dynamic seal, and can be sealed by, for example, interference fit sealing, adding sealing parts, oil sealing, etc.

[0236] Optionally, the mounting end face 115 may be the fourth end face 11241 .

[0237] To facilitate installation and removal, in some optional embodiments, see Fig.24The waterproof connector assembly 8 includes a ring seat 81 and a connector 82. The outer wall of the ring seat 81 is sealed and connected to the inner wall of the connecting ring 1132. The ring seat 81 and the connector 82 are detachably connected. A network cable channel is reserved in the connector 82. The connector 82 is used to seal and clamp the network cable. When connecting the network cable, the connector 82 is first removed from the ring seat 81, the network cable is inserted into the network cable channel of the connector 82, and the network cable connector is inserted into the network cable interface 21.

[0238] The ring seat 81 and the connector 82 may be connected in a detachable manner such as, but not limited to, a threaded connection, a linear snap-on connection, etc. For example, the ring seat 81 and the connector 82 are connected in a threaded manner, the ring seat 81 is a nut member having an internal thread, and one end of the connector 82 has an external thread that matches the nut member.

[0239] Optionally, in order to make the ring seat 81 and the connecting ring 1132 sealed and connected, for example, the ring seat 81 is a nut member formed by secondary injection molding, and the nut member can be a metal member with a plastic layer coated on the outside, and the ring seat 81 and the connecting ring 1132 are interference fit.

[0240] Optionally, the ring seat 81 and the connecting ring 1132 are clamped together, one of the ring seat 81 and the connecting ring 1132 has an annular groove, and the other has a convex ring adapted to the groove, and the convex ring is clamped in the groove, so that the ring seat 81 can be axially positioned in the connecting ring 1132.

[0243] When the network cable is inserted into the connector 82, first pass the network cable through the clamping claw 821 and the tightening head 823, then insert the network cable into the first through groove 8221 of the elastic member 822, insert the elastic member 822 into the clamping claw portion 8211, and then tighten the tightening head 823 onto the first threaded portion 8212. The tightening head 823 pushes the clamping claw portion 8211 to tighten the clamping claw portion 8211. The clamping claw portion 8211 tightens and squeezes the elastic member 822, so that the elastic member 822 clamps the network cable to achieve the clamping function. After that, the second threaded portion 8213 of the clamping claw 821 is screwed into the ring seat 81 to complete the connection.

[0244] When the clamping head 823 presses the clamping jaw portion 8211 , the clamping jaw portion 8211 deforms and contracts inwardly, thereby pressing the elastic member 822 . When the clamping head 823 leaves the clamping jaw portion 8211 , the clamping jaw portion 8211 recovers outwardly, releasing the elastic member 822 .

[0249] In some optional embodiments, the clamping head 823 has a guide surface inside, which may be an arc surface or an inclined surface. The guide surface gradually converges toward the opening of the clamping head 823, and the guide surface is used to press or loosen the clamping jaw portion 8211 to control the tightening and loosening of the clamping jaw portion 8211.

[0250] Optional, such as Fig.25As shown in , the connector 82 also includes a plug 825, and the plug 825 is detachably placed in the first slot 8221. When the interface structure is not in use, that is, when the network cable is not connected, the plug 825 can be used to block the first slot 8221 to prevent external water from penetrating through the first slot 8221.

[0251] In some optional embodiments, such as Fig.26 As shown in the figure, when plugging in the network cable, the user usually holds the connector of the network cable and inserts it into the network cable interface 21. The diameter of the inner circle of the ring seat 81 needs to be large enough to allow the thumb and index finger holding the network cable connector to enter. In order to reduce the difficulty of plugging in and improve the user experience, the diameter of the inner circle of the ring seat 81 is L1, 24 mm ≤ L1 ≤ 30 mm. Within this range, while ensuring that the thumb and index finger holding the network cable connector can enter, the volume of the interface structure is reduced as much as possible.

An elastic button 16 is disposed in the button groove 116, and the elastic button 16 is interference-fitted with the groove wall of the button groove 116. The elastic button 16 can be deformed to allow the switch 22 to be pressed or released.

[0255] The elastic button 16 can be made of elastic materials such as but not limited to rubber, silicone, etc.

[0256] The switch 22 may be a linear travel switch. The switch 22 may be a reset switch.

[0257] Optionally, the button slot 116 is located on the mounting end surface 115 , between the two first through holes 1151 .

[0258] In some optional embodiments, such as Fig.29 and Fig.30 As shown in , a first clamping hole 1163 is provided in the button groove 116, and a buckle head 162 is convexly provided on the elastic button 16, and the buckle head 162 is buckled into the first clamping hole 1163. The detachable installation function of the elastic button 16 is realized, and no other connecting parts need to be added.

[0259] The buckle head 162 can be elastically deformed. The size of the buckle head 162 is larger than that of the first clamping hole 1163. The buckle head 162 can be pressed into the first clamping hole 1163 by being deformed by extrusion. The buckle head 162 is limited after being restored.

[0260] In an optional embodiment, the number of the buckle heads 162 protruding from the elastic button 16 is two, and two first clamping holes 1163 are correspondingly provided in the button slot 116. The two first clamping holes 1163 are respectively located at the two ends of the second through hole 1164, and the buckle heads 162 are clamped in a one-to-one correspondence with the first clamping holes 1163. This embodiment can improve the stability of the elastic button 16 installed in the button slot 116, and prevent the elastic button 16 from being dislocated and rotating.

[0261] Since the elastic button 16 controls the switch 22 by pressing, the elastic button 16 is deformed when it is pressed. External water may penetrate into the base station through the gap between the elastic button 16 and the button slot 116 when the elastic button 16 is deformed, affecting the normal use of the base station.

[0262] In some optional embodiments, in order to solve the above problems, the waterproof performance of the elastic button 16 is further improved, such as Fig.29 and Fig.30 As shown, the outer ring of the elastic button 16 is formed with an outwardly protruding convex 161, and the convex convex 161 is interference-fitted with the groove wall of the button groove 116, so that the outer ring of the button groove 116 is waterproof.

[0263] A water retaining rib 1161 is convexly disposed in the button groove 116 , and the water retaining rib 1161 is located at the outer periphery of the second through hole 1164 , so as to realize waterproofing of the inner circle of the button groove 116 , while not affecting the pressing switch 22 .

[0264] like Fig.28 As shown in , the internal space enclosed by the water retaining rib 1161 is a travel cavity 1162 . The setting of the travel cavity 1162 can facilitate the deformation of the elastic button 16 .

[0265] The end surface of the elastic button 16 facing the button groove 116 is concave to form a reserved groove 165 . The water retaining rib 1161 is located in the reserved groove 165 , and the water retaining rib 1161 is closely attached to the side wall of the reserved groove 165 .

[0266] The groove wall of the reserved groove 165 facing the switch 22 is a deformation portion 164, which can be deformed under the action of external force. The deformation portion 164 can be in the shape of a thin film.

[0267] The deformation portion 164 extends toward the switch 22 to form an abutting top portion 163 . The abutting top portion 163 passes through the second through hole 1164 . The abutting top portion 163 is used to press or leave the switch 22 .

[0268] The reserved groove 165 is used to provide deformation space for the deformation portion 164 and travel space for the abutting portion 163 .

[0269] When the elastic button 16 is pressed, the deformation portion 164 is deformed toward the switch 22 under the action of external force, and the abutting top portion 163 moves toward the switch 22 until the switch 22 is pressed. When the external force is removed, the deformation portion 164 is reset, thereby driving the abutting top portion 163 away from the switch 22 to achieve reset.

[0270] In this way, when the elastic button 16 is pressed, the elastic button 16 is deformed, the convex eave 161 of the elastic button 16 squeezes the groove wall of the button groove 116, and the side groove wall of the reserved groove 165 squeezes the water retaining rib 1161. The inner ring and the outer ring are in a state of hard fit, which effectively prevents the problem of water seeping in when the elastic button 16 is pressed.

[0271] An embodiment of the present invention provides an operating system for a self-moving device, comprising any of the base stations described above, and also comprising a self-moving device, wherein the self-moving device is provided with a mobile station antenna, and the mobile station antenna is communicatively connected with the base station.

[0272] The base station is used to receive satellite signals and calculate correction data, and the rover antenna of the autonomous mobile device is used to receive satellite signals and the correction data of the base station to achieve high-precision positioning of the autonomous mobile device. The autonomous mobile device can be a snow sweeper robot, a lawn mower robot, etc.
