Description

Technical Field

[0001] This utility model relates to the field of massage equipment technology, and in particular to a junction box for a physiotherapy robot and a physiotherapy robot including the junction box for the physiotherapy robot. Background Technology

[0002] Physiotherapy massage uses various massage techniques applied to specific parts of the body to quickly relieve muscle fatigue and regulate bodily functions. Traditional physiotherapy massage is performed manually by professional massage therapists, which presents challenges due to the high workload of the therapists and significant individual differences in skill levels. However, with the rapid development of robots across various industries, physiotherapy robots have also been widely applied in massage therapy in recent years. Physiotherapy robots simulate massage movements by using a robotic arm to move a therapy head. These robotic arms typically suspend various wires, such as radio frequency head cables, massage head cables, and camera cables. Without proper organization and protection, these wires can easily become tangled due to the movement of the robotic arm, hindering its operation and potentially damaging the equipment.

[0003] The utility model patent document with authorization announcement number CN222904051U discloses a multi-functional massage robot connector. The disclosed technical solution uses a housing installed on the robotic arm to transfer various cables to avoid the lines being exposed and affecting the appearance of the device. However, the housing is not convenient for fixing some cables without connectors, and the fixing effect of the housing itself on the robotic arm still has room for improvement. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a cable transfer box for physiotherapy robots that is stable on a robotic arm and has a good cable management effect.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: a junction box for a physiotherapy robot, including a junction box shell with an internal cavity, a cable quick connector and a line tube interface respectively provided at both ends of the junction box shell, and a mechanical arm retainer fixedly connected to the bottom of the junction box shell; it also includes a line limiting hole provided at the end of the junction box shell where the cable quick connector is provided, the bottom surface of the junction box shell is an upwardly concave arc surface, and the line limiting hole is a semi-circular hole extending downward from the end surface of the junction box shell to the bottom surface of the junction box shell. This invention uses a quick-connect cable connector and a line limiting hole at the front end of the junction box housing to fix cables that need to be plugged in and those that do not, respectively, and feeds them into the line conduit through a line conduit interface at the rear end of the junction box housing. This invention improves the bottom surface of the junction box housing by making it arc-shaped, allowing for a tight fit between the bottom surface and the robotic arm, thus improving the fixing effect of the junction box housing on the robotic arm. This invention also improves the fixing effect by making the line limiting hole a semi-circular hole that can connect with the robotic arm. When the junction box housing is fixed to the robotic arm, the wires passing through the line limiting hole and introduced into the junction box housing are pressed firmly against the robotic arm, preventing wire movement and improving the organization and fixing effect of the wires.

[0006] As an improvement to the above solution: the junction box housing is detachably composed of an upper shell and a lower shell; both the upper and lower shells have semi-circular holes on their rear ends for connecting to form a conduit interface; the lower shell has a semi-circular limiting groove on its front end; and the upper shell has a circular limiting part on its front end that forms a limiting fit with the limiting groove. A cable quick connector is located on the limiting part. This invention improves the connection between the upper and lower shells by forming a limiting fit between the limiting groove on the lower shell and the limiting part on the upper shell.

[0007] As an improvement to the above solution, it also includes a positioning buckle disposed within the limiting groove, which engages with the buckle groove disposed on the limiting part. This invention, through the engagement of the positioning buckle and the buckle groove, enables rapid positioning during the assembly of the upper and lower shells, improving the assembly efficiency and post-assembly stability of the junction box housing.

[0008] As an improvement to the above solution: the robotic arm retainer is detachably connected to the lower shell by a plurality of first screws, and the lower shell is detachably connected to the upper shell by a plurality of second screws.

[0009] As an improvement to the above solution: Both ends of the robotic arm retainer are integrally connected to connecting plates. Fixing grooves adapted to the connecting plates are provided on both sides of the lower shell. The connecting plates are embedded in the corresponding fixing grooves and detachably connected to the lower shell via first screws. This invention achieves a fitting fit between the connecting plates on the robotic arm retainer and the fixing grooves on the sides of the lower shell. The fixing grooves limit the position of the connecting plates, improving the connection and fixation effect between the robotic arm retainer and the junction box housing. It also conceals the connection between the robotic arm retainer and the junction box housing, maintaining better surface flatness and improving the appearance.

[0010] As an improvement to the above solution: the bottom of the lower shell is provided with multiple upward-recessed countersunk holes, and the lower shell is detachably connected to the upper shell by a second screw inserted into the countersunk holes. This invention, by providing countersunk holes at the bottom of the lower shell to conceal the second screw used to connect the upper and lower shells, improves the aesthetic appearance.

[0011] As an improvement to the above solution, the countersunk hole is located at the intersection of the bottom and side surfaces of the lower housing. This optimization of the countersunk hole's location avoids affecting the fit between the junction box housing and the robotic arm, facilitates the installation and removal of the second screw, and improves the balance of forces at the connection point.

[0012] This utility model also discloses a physiotherapy robot, including a robotic arm, on which a physiotherapy head cable, a camera head wire, and a wiring tube are provided, and also includes a junction box for the physiotherapy robot as described above; the junction box housing is fixed to the robotic arm by a robotic arm retainer, and the wiring tube is connected to the wiring tube interface; the physiotherapy head cable is connected to a cable quick connector, and the camera head wire extends into the wiring tube after passing through the wiring limiting hole.

[0013] As an improvement to the above solution, the circuit tube is a corrugated tube.

[0014] The beneficial effects of this utility model are as follows: This utility model improves the junction box installed on the robotic arm of a physiotherapy robot by setting the bottom surface of the junction box housing as an arc surface, so that the junction box housing and the robotic arm can form a more suitable fit. The junction box housing and the robotic arm fit tightly together, which can effectively improve the fixing effect of the junction box housing on the robotic arm. At the same time, this utility model sets a wire limiting hole on the junction box housing to limit the wires that do not need to be plugged in. The semi-circular hole structure of the wire limiting hole allows the wire to contact the robotic arm before being introduced into the junction box housing, and the junction box housing presses the wire tightly on the robotic arm, thereby improving the fixing and organization effect of the wire.

[0018] In the description of this utility model, it should be noted that the terms "front", "rear", "left", "right", "up", "down", "inner", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of description and do not indicate or imply that the device or component referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0019] like Figure 1 and Figure 2 As shown, the junction box for a physiotherapy robot disclosed in this utility model includes a junction box housing 100. A cable quick connector 210 and a line limiting hole 230 are provided at the front end of the junction box housing 100, and a line conduit interface 220 is provided at the rear end of the junction box housing 100. The cable quick connector 210 is used to connect cable connectors that need to be plugged in, the line limiting hole 230 is used to organize and fix wires that do not need to be plugged in, and the line conduit interface 220 serves as a centralized outlet for multiple lines and connects to a unified conduit. The interior of the junction box housing 100 is a hollow structure, and a connector electrically connected to the cable quick connector 210 is installed within the hollow structure to realize the cable transfer function.

[0020] like Figures 1 to 3As shown, this utility model achieves the installation and fixation of the cable transfer box on the robotic arm 500 of the physiotherapy robot by installing a robotic arm retainer 400 on the cable transfer box housing 100. In order to further improve the fixing effect of the cable transfer box on the robotic arm 500, this utility model improves the bottom surface structure of the cable transfer box housing 100 by setting the bottom surface of the cable transfer box housing 100 as an upwardly concave arc surface. The curvature of the arc surface is adapted to the surface curvature of the robotic arm 500, so that when the cable transfer box housing 100 is fixed on the robotic arm 500 by the robotic arm retainer 400, it can form a tight fit with the surface of the robotic arm 500. In addition, in order to improve the arrangement and fixation of wires, the present invention sets the wire limiting hole 230 at the front end of the junction box housing 100 as a semi-circular hole, and extends the wire limiting hole 230 from the front end of the junction box housing 100 downward to the bottom surface of the junction box housing 100. This can press the wires tightly against the surface of the robotic arm 500 when the wires are introduced into the junction box housing 100, thus forming a good fixing effect on the wires.

[0021] like Figure 2 As shown, the junction box housing 100 of this utility model is detachably composed of an upper shell 110 and a lower shell 120. Both the upper shell 110 and the lower shell 120 have opposing semi-circular holes on their rear end faces. After assembly, the two semi-circular holes connect to form a conduit interface 220. A recessed limiting groove 130 is provided on the front end face of the lower shell 120, while a convex limiting part 140 is provided on the front end face of the upper shell 110. A cable quick connector 210 is disposed on the limiting part 140, which can be inserted into the limiting groove 130 to form a limiting fit. The shapes of the limiting groove 130 and the limiting part 140 are not limited, but a semi-circular limiting groove 130 and a circular limiting part 140 are preferred in this utility model. To further improve the fit between the upper shell 110 and the lower shell 120, this utility model adds a positioning buckle 131 in the limiting groove 130 and a buckle groove is provided at the bottom of the limiting part 140. The positioning buckle 131 and the buckle groove are engaged to quickly achieve positioning when assembling the upper shell 110 and the lower shell 120.

[0022] This utility model employs a simple and easy-to-implement screw connection method to achieve a detachable connection between the robotic arm retainer 440 and the lower housing 120, as well as a detachable connection between the lower housing 120 and the upper housing 110. Specifically, as shown... Figure 2As shown, connecting plates 410 are connected to both ends of the robotic arm retainer 400. Fixing grooves 150, adapted to the connecting plates 410, are provided on both sides of the lower housing 120. The connecting plates 410 are embedded in the corresponding fixing grooves 150 and are detachably connected to the lower housing 120 by multiple first screws 310. The connecting plates 410 and the robotic arm retainer 400 can be integrated to improve overall strength. Multiple upward-recessed countersunk holes 160 are provided at the bottom of the lower housing 120. The lower housing 120 is detachably connected to the upper housing 110 by multiple second screws 320 inserted into the countersunk holes 160. To avoid affecting the fit between the junction box housing 100 and the robotic arm 500, and to facilitate the installation and removal of the second screws 320, the countersunk holes 160 can be located at the intersection of the bottom and side surfaces of the lower housing 120.

[0023] This utility model also discloses, as follows: Figure 3 The illustrated physiotherapy robot is equipped with a junction box as described above. A physiotherapy head cable 510, a camera head cable 520, and a wiring conduit 530 are mounted on the robot's robotic arm 500. The junction box housing 100 is fixed to the robotic arm via a robotic arm retainer 400. The physiotherapy head cable 510 includes an RF head cable and a massage head cable with connectors, allowing selective connection of the RF head cable and / or massage head cable to the cable quick connector 210 depending on the robot's operating conditions. The wiring conduit 530 is connected to the wiring conduit interface 220 for fixed connection to the junction box housing 100. The wiring, collected and routed from the junction box housing 100, extends within the wiring conduit 530. While conventional conduit channels can be used, this invention employs a corrugated pipe with good ductility and flexibility as the wiring conduit 530. The camera head cable 520 of the physiotherapy robot passes through the line limiting hole 230 and extends into the line tube 530. The camera head cable 520 is pressed and fixed by the installation and fixation of the junction box housing 100 on the robotic arm 400.
