[0002] With the continuous development of science and technology, the application scenarios of self-moving devices are becoming more and more extensive, and are no longer limited to moving in a small range indoors stably and safely, but have begun to move in more complex and variable environments such as outdoor courtyards, and various types of courtyard robots such as lawn mowing robots and snow sweeping robots have appeared. In order to quickly obtain the current position and direction of the self-moving device and reduce the interference of environmental factors on the positioning data of the self-moving device, the applicant adopts a multi-antenna RTK (Real-time kinematic, real-time dynamic difference) system for positioning, wherein a data center module with an RTK antenna needs to be set up in a scene other than the self-moving device to assist in positioning the self-moving device. The existing data center module mainly has two technical problems in the application of assisting in positioning the self-moving device in the courtyard: firstly, the RTK antenna structure is mostly designed to be exposed, which is easy to be impacted by rain, snow, hail and other external forces in the outdoor environment, resulting in dislocation or damage of the antenna, and thus affecting the positioning accuracy and system stability; secondly, although a PoE (Power over Ethernet, power over Ethernet) power supply mode is adopted to simplify wiring and improve deployment flexibility, the commonly used Ethernet interface generally does not have a waterproof function, and it is difficult to cope with bad environments such as rainy days and snow accumulation, which has the risk of water corrosion, short circuit and the like, and restricts the long-term stable operation of the system in the outdoor environment. Therefore, there is an urgent need for a data center module with high structural reliability and suitable for outdoor environments, which should be able to effectively protect the RTK antenna from external damage and have good waterproof performance while realizing PoE power supply, so as to ensure the high-precision positioning of the self-moving device in the courtyard and the long-term stable operation of the system in the complex environment.

[0030] Please refer to Figs. 1 to 4, the anti-dislocation structure in the embodiments of the present application includes a shell 1, an antenna 2, a limiting piece 3 and a pressing piece 4. The shell 1 is provided with a mounting wall 11, and the antenna 2 is arranged on the mounting wall 11.

The elastic member 822 is arranged inside the clamping jaw portion 8211, and the elastic member 822 is formed with a first through slot 8221 inside.

[0068] The cap 823 is provided with an opening. The hollow inside of the clamping jaw 821, the first through slot 8221 of the elastic member 822 and the opening of the cap 823 cooperatively form a wire passing channel of the connector 82.

[0069] When the network cable is clamped into the connector 82, the network cable is first passed through the clamping jaw 821 and the cap 823, and then the network cable is clamped into the first through slot 8221 of the elastic member 822. The elastic member 822 is then inserted into the clamping jaw portion 8211, and then the cap 823 is screwed onto the first threaded portion 8212. The cap 823 pushes the clamping jaw portion 8211 to make the clamping jaw portion 8211 contract, and the clamping jaw portion 8211 contracts to press the elastic member 822, so that the elastic member 822 clamps the network cable to achieve the clamping function. Then the second threaded portion 8213 of the clamping jaw 821 is screwed into the ring seat 81 to complete the connection.

[0070] When the cap 823 presses the clamping jaw portion 8211, the clamping jaw portion 8211 deforms and contracts inwardly to press the elastic member 822. When the cap 823 is away from the clamping jaw portion 8211, the clamping jaw portion 8211 restores outwardly to release the elastic member 822.

[0071] Optionally, in order to facilitate the network cable to be clamped into the first through slot 8221 of the elastic member 822, the elastic member 822 is provided with a radial notch 8222, and the network cable can pass through the notch 8222 and then be clamped into the first through slot 8221.

[0072] Optionally, as shown in Fig. 8, the clamping jaw 821 is hollow inside, and the clamping jaw 821 is sequentially distributed with the clamping jaw portion 8211, the first threaded portion 8212, a force applying portion 8214 and the second threaded portion 8213 along the axial direction. The force applying portion 8214 can be held and rotated by the installer. The force applying portion 8214 can be but is not limited to a variable prism, which can be used to cooperate with an external tool to increase the torque for easy rotation.

[0073] The clamping jaw portion 8211 can be a plurality of axially extending claw bodies, and the plurality of claw bodies are arranged in a circumferential interval. The end of the clamping jaw portion 8211 can be contracted towards the axial center.

[0074] Optionally, as shown in FIG. 8, the joint 82 further comprises a sealing ring 824, which is arranged between the force applying part 8214 and the ring seat 81 to improve the sealing of the waterproof joint assembly 8.

[0075] In some optional embodiments, the cap 823 has a guide surface inside, which can be a curved surface or an inclined surface, and the guide surface gradually converges towards the opening of the cap 823, and the guide surface is used to press or loosen the clamping jaw part 8211 to control the tightening and loosening of the clamping jaw part 8211.

[0076] Optionally, as shown in FIG. 8, the joint 82 further comprises a plug 825, which is detachably arranged in the first through groove 8221. When the interface structure is not used, i.e. the network cable is not connected, the plug 825 can be used to plug the first through groove 8221 to prevent external water from seeping in through the first through groove 8221.

[0077] In some optional embodiments, as shown in FIG. 8, since the network cable is usually inserted into the network cable interface 021 by the user holding the joint of the network cable, the inner diameter of the inner circle of the ring seat 81 needs to be large enough to allow the thumb and index finger holding the joint of the network cable to enter. In order to reduce the difficulty of plugging and improve the user experience, the inner diameter of the inner circle of the ring seat 81 is L1, and 24mm≤L1≤30mm. Within this range, while ensuring that the thumb and index finger holding the joint of the network cable can enter, the volume of the interface structure is as small as possible.

[0078] In some optional embodiments, as shown in FIG. 10, since the network cable is usually inserted into the network cable interface 021 by the user holding the joint of the network cable, the depth of the network cable interface 021 cannot be too deep and should be as small as possible to not exceed the second knuckle of the index finger. In order to facilitate the plugging of the network cable and improve the user experience, the distance between the end face of the connection ring 7 away from the network cable interface 021 and the network cable interface 021 is L2, and 10mm≤L2≤20mm. Within this range, while ensuring that the network cable can be flexibly plugged and the water blocking effect of the connection ring 7 is achieved, the volume of the connection ring 7 is as small as possible.

[0079] As shown in FIGS. 5-7, the data center module of the embodiment of the application is used to provide high-precision reference data and real-time correction information, so that the flow station can quickly and accurately determine its own position.

[0080] The data center module can include a housing 01 and a circuit board 02 arranged in the housing 01, and further include any of the above-mentioned interface structures and at least one anti-displacement structure as described above. The shell 1 is part of the housing 01, the antenna 2 is electrically connected to the circuit board 02, and the network cable interface 021 is electrically connected to the circuit board 02.

[0081] For example, the data center module has three anti-displacement structures as described above, which are distributed at two ends in the horizontal direction and one end in the vertical direction.

[0082] Optionally, as shown in FIG. 10, the casing 01 can include a shell 1 and a cover 1b, which are covered with each other.

[0083] Optionally, the shell 1 can also be regarded as a partial structure of the casing 01. For example, the data center module can include two interface structures as described above, which are both located on the same casing 01, as shown in FIG. 7.

[0084] In order to improve the waterproof function of the switch 022 on the data center module, in some optional embodiments, please refer to FIGS. 11-13, the switch 022 is electrically connected to the circuit board 02, the shell 1 is formed with a button slot 12a, the button slot 12a is provided with a second through hole 124a, and the switch 022 is aligned with the second through hole 124a. The button slot 12a is provided with an elastic button 9, which is arranged in the button slot 12a. The elastic button 9 is in interference fit with the slot wall of the button slot 12a, and the elastic button 9 can be deformed to press or leave the switch 022.

[0085] The elastic button 9 can be made of, but not limited to, elastic materials such as rubber and silicone.

[0086] The switch 022 can be a linear travel switch. The switch 022 can be a reset switch.

[0087] Optionally, the button slot 12a is located on the mounting end face 11a between the two first through holes 111a.

[0088] In some optional embodiments, as shown in FIGS. 12 and 13, the button slot 12a is provided with a clamping hole 123a, and the elastic button 9 is provided with a buckle head 92, which is buckled into the clamping hole 123a. The elastic button 9 can be detachably installed, and no other connecting parts are needed.

[0089] The buckle head 92 can be elastically deformed, and the size of the buckle head 92 is greater than that of the clamping hole 123a. The buckle head 92 can be pressed into the clamping hole 123a by extrusion deformation, and the buckle head 92 is limited after recovery.

[0090] In an optional embodiment, the number of the buckle heads 92 protruding from the elastic button 9 is two, and the button slot 12a is provided with two clamping holes 123a corresponding to the two buckle heads 92, respectively. The buckle heads 92 and the clamping holes 123a are one-to-one corresponding to buckling. This embodiment can improve the stability of the elastic button 9 installed in the button slot 12a, and prevent the elastic button 9 from being dislocated and rotated.

[0091] Since the elastic button 9 controls the switch 022 by pressing, when the elastic button 9 is pressed, the elastic button 9 deforms, and the external water flow may seep into the data center module from the gap between the elastic button 9 and the button groove 12a when the elastic button 9 deforms, affecting the normal use of the data center module.

[0092] In some optional embodiments, in order to solve the above problems and further improve the waterproof performance of the elastic button 9, as shown in FIGS. 12 and 13, the outer circle of the elastic button 9 is formed with an outward convex eave 91, and the eave 91 is in interference fit with the groove wall of the button groove 12a. The waterproof of the outer circle of the button groove 12a is achieved. The inner convex water retaining rib 121a of the button groove 12a is located at the outer periphery of the second through hole 124a. The waterproof of the inner circle of the button groove 12a is achieved, while not affecting the pressing of the switch 022.

[0093] As shown in FIG. 11, the internal space enclosed by the water retaining rib 121a is a stroke cavity 122a, and the stroke cavity 122a is provided to facilitate the deformation of the elastic button 9. The end face of the elastic button 9 towards the button groove 12a is concave to form a reserved groove 95, and the water retaining rib 121a is located in the reserved groove 95 and tightly abuts the side wall of the reserved groove 95. The groove wall of the reserved groove 95 towards the switch 022 is a deformation part 94, which can deform under external force. The deformation part 94 can be in the form of a film. The deformation part 94 extends towards the switch 022 to form a stop part 93, which passes through the second through hole 124a and is used to press or move away from the switch 022. The reserved groove 95 is used to give the deformation space of the deformation part 94 and the stroke space of the stop part 93. When the elastic button 9 is pressed, the deformation part 94 deforms towards the switch 022 under external force, and the stop part 93 moves towards the switch 022 until the switch 022 is pressed. When the external force is removed, the deformation part 94 resets, thereby driving the stop part 93 away from the switch 022 to reset. In this way, when the elastic button 9 is pressed, the elastic button 9 deforms, the eave 91 of the elastic button 9 extrudes the groove wall of the button groove 12a, and the side wall of the reserved groove 95 extrudes the water retaining rib 121a. The inner circle and the outer circle are in over-tight fit state, effectively preventing the problem that water may seep in when the elastic button 9 is pressed
