Description

Technical Field

[0001] This utility model relates to a structural component of a hair-drying robot, and in particular to a lifting bracket for the hair-drying robot. Background Technology

[0002] A hair-drying robot is a vertical intelligent hair-drying device, structurally consisting of a base, a lifting frame, and a swing arm support. The lifting frame supports the swing arm support, which moves the blower end during operation. Existing hair-drying robots, in order to recognize information such as body height and hair position, have sensors at the end of the swing arm support. This requires long cables to connect the main control circuit board and the sensor circuit board to transmit sensor signals. These cables bend continuously with the movement of the robotic arm, posing a risk of damage over long-term use. Furthermore, the sensor signal transmission lines are susceptible to electromagnetic interference as they pass near motors, transformers, and other equipment. The sensor position changes with movement, requiring additional coordinate transformation calculations to determine the final positioning result. The robotic arm's vibrations introduce uncertainties and interference into the sensor's imaging. Utility Model Content

[0003] The embodiments of this application provide a hair-drying robot lifting bracket, which is mainly used to solve the shortcomings of existing sensors installed at the end of the swing arm bracket in terms of mechanical structure and signal stability.

Detailed Implementation

[0016] The following detailed description, in conjunction with specific embodiments and accompanying drawings, clarifies that the described embodiments are only a portion, not all, of the embodiments. All other embodiments obtained by those skilled in the art based on the following embodiments without inventive effort are also within the scope of protection of this utility model.

[0017] It should be understood that if the controllers or control circuits involved in the embodiments are conventional control technologies or units for those skilled in the art, such as the controller's control circuit, they can be implemented by those skilled in the art using existing technologies.

[0018] The disclosure of the embodiments provides many different implementations or examples for different solutions to implement this utility model. To simplify the disclosure of this utility model, the components and arrangements of specific examples are described in the embodiments. Of course, these are merely examples and are not intended to limit the utility model. Furthermore, reference numerals and / or reference letters may be repeated in different examples in the embodiments; this repetition is for simplification and clarity and does not in itself indicate a relationship between the various implementations and / or arrangements discussed. In addition, if examples of various specific processes and materials are provided in the embodiments, those skilled in the art will recognize the application of other processes and / or the use of other materials.

[0019] In this embodiment, the hair-drying robot lifting bracket is used to connect the base a and the swing arm bracket, serving as a support for the swing arm bracket with the help of the base, and can adjust the height of the swing arm bracket by its own lifting.

[0020] like Figures 1-6 As shown, the hair-drying robot lifting mechanism in this embodiment includes a connector assembly 1 and a support assembly 2, wherein the connector assembly 1 is located above the support assembly 2; The connector assembly 1 includes a connector housing 11, a module guide spool 12 and an inner fixing seat 13 are provided inside the connector housing 11, a circuit board 14 is provided on the inner fixing seat 13, a sensor 15 is provided on the circuit board 14, and a sensor lens 16 is provided on the connector housing 11 at the position corresponding to the sensor 15. The inner fixed seat 13 is also provided with a lifting motor 17. The bracket assembly 2 includes a sleeve assembly 21 and a lead screw assembly 22. The lifting motor 17 is connected to the lead screw assembly 22, and the sleeve assembly 21 is sleeved on the outside of the lead screw assembly 22.

[0021] Compared to existing technologies, the primary technical problem solved by this embodiment is that by setting up the connector assembly, the circuit board 14 and the sensor 15 are structurally integrated into the connector assembly. This allows the sensor to detect the height and position of the human body and hair from fixed coordinates during the operation of the hair-drying robot. Its position is not affected by the swing arm of the hair-drying robot. The bending, extension, and rotation of the swing arm do not change the detection direction and position of the sensor. When acquiring signals for position calculation, it does not require complex coordinate conversion. Moreover, the sensor is closer to the main control, which reduces signal transmission loss and strengthens anti-interference capabilities.

[0022] Secondly, this embodiment further solves the problem of centralized component installation by also installing the lifting motor in the connector assembly. Centralized component installation has the advantages of small space occupation and easy assembly. The following further elaborates on the various structural details.

[0023] Due to the aforementioned technical objectives, the connector housing of this embodiment has three functional parts: connecting the swing arm, mounting components, and connecting the bracket. Therefore, in this embodiment, the connector housing 11 includes a swing arm connecting section 111, a middle transition section 112, and a bracket connecting section 113. The swing arm connecting section 111 is located on the first side of the middle transition section 112 and extends upward, while the bracket connecting section 113 is located on the second side of the middle transition section 112 and extends downward.

[0024] The module wire guide shaft 12 has two main functions: first, to provide support and swing axis for the swing arm; and second, to allow the wire harness connected to the components in the swing arm to pass through. Therefore, in this embodiment, the module wire guide shaft 12 is provided on the swing arm connecting section 111, and the module wire guide shaft 12 has a hollow shaft body that protrudes upward from the swing arm connecting section.

[0025] In addition, in this embodiment, in order to further constrain the wire harness passing through the module guide spool 12 from the inside, a guide seat 18 is also provided inside the swing arm connecting section corresponding to the module guide spool.

[0026] Preferably, the swing arm connecting section is further provided with an interface circuit board, and the outer wall of the swing arm connecting section is provided with an interface. The interface on the interface circuit board is used for generating tests and inspections, and for connecting data cables to communicate test data. It is usually a Type-C interface.

[0027] As a core component in the installation of the circuit board, sensor, and motor in this embodiment, the inner fixing base 13 includes a circuit board mounting section 131 and a motor mounting section 132. The circuit board mounting section 131 is sleeved in the bracket connecting section 113 of the connector housing 11, and the motor mounting section 132 is located below the circuit board mounting section 131. The circuit board mounting section 131 is used to mount the circuit board, which can be a single circuit board or composed of multiple circuit boards. Regarding the internal component layout, in this embodiment, the circuit board 14 includes a main control circuit board 141 and a sensor circuit board 142. The sensor 15 is mounted on the sensor circuit board 142. The main control circuit board 141 has a button 143, and the connector housing 11 has a button 114 corresponding to the button. The main control circuit board 141 is used for device control, including user operation input, sensor signal input, processing of control commands and sensor signals, and execution of processed functions. The sensor circuit board is mainly used to set up the sensor and send the sensor signals to the main control circuit board 141.

[0028] like Figure 5 As shown, in this embodiment, in order to accommodate the main control circuit board 141 and the sensor circuit board 142, the circuit board mounting section 131 has a mounting plane on the side where the main control circuit board 141 and the sensor circuit board 142 are mounted. The mounting plane is formed by a plurality of studs provided inside the circuit board mounting section 131. The main control circuit board 141 and the sensor circuit board 142 are respectively mounted on the studs by screws.

[0029] In actual use, since the sensor's detection direction is facing the human body, and the buttons on the device are also facing the human body for the convenience of the user, in this embodiment, the main control circuit board 141 and the sensor circuit board 142 are located on the same mounting plane.

[0030] Combination Figure 1 , Figure 7 and Figure 8As shown, in this embodiment, since the lifting of the lifting bracket is driven and controlled by a lead screw assembly, a sleeve assembly 21 is provided outside the lead screw assembly 22 to conceal the lead screw assembly inside the device. The sleeve assembly 21 includes an outer tube 211 and an inner tube 212. The upper part of the inner tube 212 is sleeved on the outside of the motor mounting section 132 of the inner fixed seat 13, and the outer tube 211 is sleeved on the outside of the inner tube 212. The bottom of the outer tube 211 is mounted on the base. When the device is adjusted for lifting, the bottom of the outer tube 211 is fixed on the base and does not move up or down, while the inner tube 212 rises with the inner fixed seat 13, thus always enclosing the extended lead screw assembly within it.

[0031] Regarding the installation method of the outer tube 211 and the inner tube 212, the bottom of the outer tube is provided with an internal thread, which mates with the external thread on the base. The installation is achieved by rotation. Similarly, the upper end of the inner tube 212 is provided with an internal thread, and the bottom of the bracket connecting section 113 of the connector housing 11 is provided with an external thread. The installation is achieved by rotation.

[0032] Since both ends of the sleeve assembly 21 need to be threaded to corresponding components, it would be very difficult to calculate the number of thread turns and the locking position if the orientation between the connector housing 11 and the base is to be precisely controlled by controlling the threads. To solve this problem, in this embodiment, the bottom of the inner tube 212 is provided with a lower positioning seat 213, and the outer wall of the lower positioning seat 213 is provided with a vertical outer positioning groove 214. The inner side of the outer tube 211 is provided with a corresponding inner positioning groove 215. When the outer tube 211 is sleeved on the outside of the inner tube 212, the outer tube 211 and the inner tube 212 are first fixed to the corresponding components by threads, and then the mating angle of the inner positioning groove 215 and the outer positioning groove 214 can be used to precisely control the mating direction of the outer tube 211 and the inner tube 212.

[0033] In this embodiment, the lead screw assembly 22 includes a lead screw 221 and a lead screw sleeve 222. The top of the lead screw 221 is connected to the output shaft of the lifting motor 17, and the lead screw sleeve 222 is sleeved around the lead screw 221. The bottom of the lead screw sleeve 222 is mounted on the base. When the lifting motor 17 drives the lead screw 221 to rotate, the lead screw 221 can rise and fall relative to the lead screw sleeve 222, thereby driving the connector assembly 1 to rise and fall, achieving the purpose of height adjustment.

[0034] like Figure 3As shown, in order to reduce the vibration of the lifting motor 17 during operation and reduce the noise of the equipment during operation, in this embodiment, the bottom of the motor mounting section 132 has a motor mounting plate 133, the lifting motor 17 is fixed on the motor mounting plate 133, and buffer pads 134 are respectively provided on both sides of the motor mounting plate 133.

[0035] The above description is merely a preferred embodiment of the present application and does not limit the scope of disclosure of the embodiments of the present application. Any equivalent structural or procedural transformations made using the description and drawings of the embodiments of the present application, or direct or indirect applications in other related technical fields, are similarly included within the scope of patent protection supported by the embodiments of the present application.
