Description

Technical Field

[0001] This utility model relates to the field of communication technology, and in particular to a portable robot control signal transmission device. Background Technology

[0002] The robot control signal transmission device is a neural network that connects the robot control core with various execution units (such as servo motors, sensors, and end effectors). It is responsible for encoding the instructions generated by the controller into electrical or optical signals of a specific protocol and transmitting them in real time and with high reliability through wired (such as EtherCAT, CAN bus) or wireless (such as Wi-Fi, 5G) communication links. At the same time, it receives feedback data from sensors to ensure that the robot can complete complex actions accurately and in a coordinated manner.

[0003] The interfaces (such as connectors and antennas) of existing portable robot control signal transmission devices are mostly fixed designs. In complex or confined environments, this structure is easily subjected to external forces or collisions, which can lead to physical damage to the interface or poor contact due to vibration. This directly affects the stability and reliability of signal transmission and limits its application in harsh working conditions. Utility Model Content

[0004] One objective of this invention is to provide a portable robot control signal transmission device. This invention addresses the problem that the interfaces (such as connectors and antennas) of existing portable robot control signal transmission devices mentioned in the background are mostly fixed designs. In complex or confined environments, this structure is easily subjected to external forces or collisions, leading to physical damage to the interface or poor contact caused by vibration.

[0005] A portable robot control signal transmission device according to an embodiment of the present invention includes: Signal transmission components, including the device body and connectors connected via a universal joint; The universal joint includes an outer ball frame and an inner ball frame that is movably disposed inside the outer ball frame. The outer ball frame is fixedly installed to the equipment body by a fixing bracket. A connecting cylinder is fixedly disposed at one end of the inner ball frame. Cable outlets are opened at the other ends of the outer ball frame, the inner ball frame, and the fixing bracket. A dustproof component is installed between the outer ball frame and the inner ball frame.

[0006] Preferably, the bottom of the device body is provided with a storage groove, and a bracket is rotatably installed at one end of the storage groove.

[0007] Preferably, a limiting groove is provided inside the storage slot at the end position corresponding to the bracket, and the limiting groove is a sloping structure.

[0008] Preferably, there are multiple universal joints and connectors.

[0009] Preferably, the fixing frame is fixed to the outside of the outer spherical frame, and the fixing frame and the equipment body are fixed together by bolts.

[0010] Preferably, the connecting sleeve in the connector and universal joint is threaded.

[0011] Preferably, the dustproof component includes a dustproof sleeve that engages with one end of the outer ball frame, and the other end of the dustproof sleeve is sleeved on the outside of the connecting cylinder at the end of the inner ball frame. The other end of the dustproof sleeve and the connecting cylinder are fixed by a locking component.

[0012] Preferably, the locking assembly includes a clamping ring sleeved on the outside of the dust cover, with positioning rings fixedly provided on both sides of the clamping ring. The positioning ring has a column inside, with a screw rotatably provided inside the column on the left side. The screw is threadedly installed with the column on the right side, and a knob is fixedly provided at the end of the screw.

[0013] The beneficial effects of this utility model are: 1. This utility model effectively avoids physical damage and poor contact caused by external pulling or collision of the interface through the universal mechanism. When the connector or its connected cable is pulled, bent or collided from any direction, the external force will not be directly applied to the rigid connection point between the connector and the device body. Instead, the force is converted into a buffer displacement by the multi-angle universal deflection of the inner ball frame inside the outer ball frame, which greatly alleviates stress concentration and protects the connector and internal circuits from damage. At the same time, the dust cover in the dustproof assembly is engaged with the outer side of the outer ball frame and sleeved on the connecting cylinder at the end of the inner ball frame. The clamping ring in the locking assembly is sleeved on the outside of the dust cover. Rotating the knob causes the screw to move in the threaded part of the positioning ring, thereby tightening the clamping ring and fixing the position of the dust cover. This can maintain a seal when the universal mechanism is moving, preventing dust, moisture and other impurities from entering and affecting the internal electrical connection. It also ensures that the connector and the device body can maintain a stable and reliable electrical contact during dynamic deflection. 2. This utility model effectively avoids the problem by setting up a storage slot, a limiting slot, and a bracket. When the device needs to be carried or stored, the bracket can be completely rotated and stored in the storage slot at the bottom of the device body, keeping the bottom of the device flat and making it easy to put into a backpack or toolbox, while protecting the bracket itself from external damage. When the device needs to be placed on a flat surface such as a table or the ground for operation, the bracket can be rotated out of the storage slot and its end can be inserted into the limiting slot. Since the limiting slot is a sloping structure, the end of the bracket will be locked into the lowest point of the slope, forming a stable triangular support structure, thereby providing a reliable standing posture for the device to facilitate operation.

[0016] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.

[0017] refer to Figures 1-4 A portable robot control signal transmission device, comprising: The signal transmission component 1 includes a device body 101 and a connector 102 connected by a universal mechanism 2. The bottom of the device body 101 is provided with a storage groove 103, and a bracket 105 is rotatably provided at one end of the storage groove 103. When the device needs to be carried or stored, the bracket 105 can be completely rotated and stored in the storage slot 103 at the bottom of the device body 101, keeping the bottom of the device flat and making it easy to put into a backpack or toolbox, while protecting the bracket 105 itself from external damage. When the device needs to be placed on a flat surface such as a table or the ground for operation, the bracket 105 can be rotated out of the storage slot 103 and its end can be inserted into the limiting slot 104. Since the limiting slot 104 is a sloping structure, the end of the bracket 105 will be inserted into the lowest point of the slope, forming a stable triangular support structure, thereby providing a reliable standing posture for the device to facilitate operation. The universal joint 2 includes an outer ball frame 201 and an inner ball frame 203 that is movably disposed inside it. The outer ball frame 201 is fixedly installed to the equipment body 101 via a fixing frame 202. A connecting cylinder 204 is fixedly disposed at one end of the inner ball frame 203. Cable outlets 205 are opened at the other ends of the outer ball frame 201, the inner ball frame 203 and the fixing frame 202. A dustproof component is installed between the outer ball frame 201 and the inner ball frame 203. When the connector 102 or its connected cable is subjected to pulling, bending or collision from any direction, the external force will not act directly on the rigid connection point between the connector 102 and the device body 101. Instead, the force is converted into a buffer displacement by the inner ball frame 203 deflecting in multiple angles inside the outer ball frame 201, thereby greatly alleviating stress concentration and protecting the connector 102 and internal circuits from damage. The dustproof component includes a dustproof sleeve 206 that engages with one end of the outer ball frame 201, and the other end of the dustproof sleeve 206 is sleeved on the outside of the connecting cylinder 204 at the end of the inner ball frame 203. The other end of the dustproof sleeve 206 and the connecting cylinder 204 are fixed together by a locking component. The locking assembly includes a clamping ring 207 sleeved on the outside of the dust cover 206. Positioning rings 208 are fixedly provided on both sides of the clamping ring 207. A column 209 is provided inside the positioning ring 208. A screw 210 is rotatably provided inside the left column 209. The screw 210 is threadedly installed with the right column 209. A knob 211 is fixedly provided at the end of the screw 210. The dust cover 206 in the dustproof assembly is engaged with the outer ball frame 201 and sleeved on the connecting cylinder 204 at the end of the inner ball frame 203. The clamping ring 207 in the locking assembly is sleeved on the outside of the dust cover 206. Rotating the knob 211 causes the screw 210 to move in the internal thread of the column 209 of the positioning ring 208, thereby tightening the clamping ring 207 and fixing the position of the dust cover 206. This can maintain a seal when the universal mechanism 2 is moving, preventing dust, moisture and other impurities from entering and affecting the internal electrical connection, and ensuring that the connector 102 and the equipment body 101 can still maintain a stable and reliable electrical contact during dynamic deflection.

[0018] Example 1: A limiting groove 104 is provided inside the storage slot 103 corresponding to the end position of the bracket 105. The limiting groove 104 is a ramp structure. When the bracket 105 is rotated out of the storage slot 103 to support the equipment, its end can be embedded in the limiting groove 104 of the ramp structure. Due to the guiding and limiting effect of the ramp, the bracket 105 can be stably locked at the preset support angle to form a solid triangular support structure. The universal mechanism 2 and the connector 102 are provided in several units. Multiple interfaces with universal buffer function can be configured at different positions of the device body 101 according to actual needs. For example, power interface, data interface and antenna interface can be set at the same time to meet the needs of simultaneous connection and transmission of multiple devices and multiple signals, which significantly improves the versatility and expandability of the device.

[0019] Example 2: The fixing frame 202 is fixed to the outside of the outer ball frame 201. The fixing frame 202 and the equipment body 101 are fixed with bolts, which ensures the firmness and reliability of the connection between the universal mechanism 2 and the equipment body 101. It is convenient to disassemble, maintain or replace when needed. The connector 102 and the connecting cylinder 204 in the universal mechanism 2 are threaded, which makes the installation and replacement of the connector 102 extremely convenient. When a certain interface is damaged or needs to be replaced with a different type of interface, it is not necessary to disassemble the entire universal mechanism. It can be quickly replaced by simply unscrewing it from the connecting cylinder 204. This greatly improves the maintenance efficiency of the device, reduces the use cost, and enhances the practicality and economy of the product.

[0020] Working principle: First, when the device needs to be placed for operation, the bracket 105 at the bottom of the device body 101 is rotated out of the storage groove 103, so that its end is embedded in the limiting groove 104 of the ramp structure, forming a stable triangular support structure; then, when the connector 102 or its cable is pulled by an external force, the external force drives the inner ball frame 203 to deflect in all directions inside the outer ball frame 201 fixed on the device body 101, converting rigid impact into buffer displacement, thereby protecting the connector 102 and internal circuitry; during this dynamic deflection process, the outer ball frame 201 and the connecting cylinder 204 are fitted together. The outer dust cover 206 deforms accordingly, and the screw 210 is tightened by rotating the knob 211 to tighten the clamping ring 207, thus firmly locking the dust cover 206 and ensuring that it always fits tightly, effectively preventing dust and moisture from entering and maintaining the stability of the internal electrical connection. When maintenance or replacement is required, the entire universal mechanism 2 can be removed by unscrewing the fixing bracket 202 with bolts, or the connector 102 can be directly unscrewed from the connecting cylinder 204 for replacement, which is convenient and efficient. After use, the bracket 105 is loosened and completely stored in the storage slot 103, making the bottom of the device flat and easy to carry and store.

[0021] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
