Description

Technical Field

[0001] This utility model belongs to the field of robotics technology, and more specifically, relates to a service robot. Background Technology

[0002] Artificial intelligence technology is being widely applied in various aspects of daily life, and service robots are playing an increasingly important role in various industries. For example, delivery robots are gradually playing an important role in express delivery, restaurant delivery, hotel delivery, and vending machines; cleaning robots can perform functions such as vacuuming, dust mopping, washing, sweeping, and polishing in restaurants, hotels, and plazas; and inspection robots are widely used in daily security inspections, power line inspections, and logistics transportation. Therefore, a comprehensive robot service solution has emerged, using a universal chassis to adapt to multiple functional modules, thus enabling multi-functional service robots. However, due to vibrations of different frequencies and accelerations during robot movement, and assembly tolerances between the functional modules and the robot's dimensions and assembly, conductive springs combined with guiding structures are conventionally used to provide power and control signals to the functional modules.

[0003] Using conventional conductive spring solutions has several drawbacks: signal transmission interruption problem. If the robot encounters a large threshold or trench during its movement, the contact point of a single spring may experience a signal interruption time of more than 1µs due to vibration, causing the functional module to fail due to power or signal disconnection. Therefore, a multi-spring solution with different directions is needed to avoid the risk, but this will increase the difficulty of wiring and limit the structural design. Utility Model Content

[0004] The purpose of this utility model embodiment is to provide a service robot to solve the technical problem in the prior art where the signal is easily disconnected when the conductive spring is used due to vibration.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A service robot is provided, comprising a universal base, a functional module, and a floating quick-connect connector. The floating quick-connect connector includes a male connector end and a female connector end that can be plugged into each other. One of the male connector end and the female connector end is floatingly disposed on one of the universal base and the functional module, while the other of the male connector end and the female connector end is fixedly disposed on the other of the universal base and the functional module. The male connector end includes a conductive pin, and the female connector end has a conductive socket that cooperates with the conductive pin. The plugging direction of the male connector end and the female connector end is a first direction, and the relative floating direction of the male connector end and the female connector end is perpendicular to the first direction.

[0006] Optionally, the male connector is floatingly disposed on the universal base, and the female connector is fixed to the functional module. The male connector includes a male connector socket floatingly disposed on the universal base, a conductive pin fixed to the male connector socket, and a connector for connecting the male connector and the universal base.

[0007] Optionally, the male connector has a first connecting hole, the universal base has a second connecting hole, the connector includes a screw, the screw passes through the first connecting hole and is threaded into the second connecting hole, and the inner diameter of the first connecting hole is larger than the major diameter of the screw.

[0008] Optionally, the male connector further includes a floating seat, which includes a cylindrical portion and two first skirt portions. The two first skirt portions are formed by radially outward extension from both ends of the cylindrical portion. The cylindrical portion is located inside the first connecting hole, and the first skirt portions abut against the surface of the male connector at the periphery of the first connecting hole. The screw passes through the cylindrical portion, and the outer peripheral wall of the cylindrical portion and the inner peripheral wall of the first connecting hole are spaced apart.

[0009] Optionally, a nesting cylinder is fixed to the inner peripheral wall of the first connecting hole, the cylindrical portion is located inside the nesting cylinder, and there is a gap between the nesting cylinder and the cylindrical portion.

[0010] Optionally, the gap between the inner peripheral wall of the nested cylinder and the outer peripheral wall of the cylindrical portion is 0.15 mm to 0.2 mm.

[0011] Optionally, the two ends of the nested cylinder extend radially outward to form a second skirt portion, the male connector seat is provided with a groove around the first connecting hole, the second skirt portion is located in the groove, and the side of the second skirt portion facing away from the groove is flush with the surface of the male connector seat.

[0012] Optionally, one of the male end and the female end of the connector is provided with a guide post, and the other is provided with a guide hole.

[0013] Optionally, the circumferential inner wall of the conductive socket has a torsion spring for contacting and communicating with the conductive pin.

[0014] Optionally, the service robot further includes a guide rail structure, which includes mutually cooperating guide recesses and guide protrusions. The cross-section of the guide protrusion gradually increases from its top to its root. The guide recess is located in one of the universal base and the functional module, and the guide protrusion is located in the other of the universal base and the functional module.

[0015] The beneficial effects of the service robot provided by this utility model are as follows: Compared with the prior art, the service robot of this utility model includes a universal base, a functional module, and a floating connector. One of the male and female connector ends is floating, while the other is fixed. Since the male connector end can float relative to the female connector end, when the service robot encounters a large threshold or groove, the functional module may vibrate and shift relative to the universal base.

It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

When a component is referred to as being "connected to" another component, it can be directly connected to or indirectly connected to that other component.

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element 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.

[0029] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0030] Artificial intelligence technology is being widely applied in various aspects of daily life, and service robots are playing an increasingly important role in various industries. For example, delivery robots are gradually playing an important role in express delivery, restaurant delivery, hotel delivery, and vending machines; cleaning robots can perform functions such as vacuuming, dust mopping, washing, sweeping, and polishing in restaurants, hotels, and plazas; and inspection robots are widely used in daily security inspections, power line inspections, and logistics transportation. Therefore, a comprehensive robot service solution has emerged, using a universal chassis to adapt to multiple functional modules, thus enabling multi-functional service robots. However, due to vibrations of different frequencies and accelerations during robot movement, and assembly tolerances between the functional modules and the robot's dimensions and assembly, conductive springs combined with guiding structures are conventionally used to provide power and control signals to the functional modules.

[0031] Using conventional conductive spring solutions has several drawbacks: signal transmission interruption problem. If the robot encounters a large threshold or trench during its movement, the contact point of a single spring may experience a signal interruption time of more than 1µs due to vibration, causing the functional module to fail due to power or signal disconnection. Therefore, a multi-spring solution with different directions is needed to avoid the risk, but this will increase the difficulty of wiring and limit the structural design.

[0032] To address the aforementioned technical issues, this utility model proposes a service robot, comprising a universal base 10, a functional module 20, and a floating quick-connect connector 30. The floating quick-connect connector 30 includes a male connector end 31 and a female connector end 32 that are mutually plugged in. The male connector end 31 or the female connector end 32 is floating, so when the service robot encounters thresholds, grooves, or other obstacles that cause it to vibrate, the floating male connector end 31 or the female connector end 32 can adjust its position to always maintain the mutual plugging of the male connector end 31 and the female connector end 32, thus preventing signal disconnection when the robot vibrates and ensuring a stable connection between the universal base 10 and the functional module 20.

[0033] The service robot provided in the embodiments of this utility model will now be described.

[0034] Please refer to the following: Figures 1 to 3The service robot includes a universal base 10, a functional module 20, and a floating quick-connect connector 30. The floating quick-connect connector 30 includes a male connector end 31 and a female connector end 32 that can be plugged into each other. One of the male connector end 31 and the female connector end 32 is floatingly disposed on one of the universal base 10 and the functional module 20, and the other of the male connector end 31 and the female connector end 32 is fixedly disposed on the other of the universal base 10 and the functional module 20. The male connector end 31 includes a conductive pin 312, and the female connector end 32 has a conductive socket 321 that cooperates with the conductive pin 312. The plugging direction of the male connector end 31 and the female connector end 32 is a first direction, and the relative floating direction of the male connector end 31 and the female connector end 32 is perpendicular to the first direction.

[0035] Different types of service robots can use the same universal base 10. By designing different functional modules 20 and electrically connecting the functional modules 20 to the universal base 10, different types of service robots can be formed, which can reduce design costs and material costs.

[0036] The universal base 10 generally has functions such as walking, map scanning, and positioning. The universal base 10 can be used with different functional modules 20. The universal base 10 is generally located at the bottom of the functional module 20 and needs to form a structural interconnection and a circuit interconnection with the functional module 20.

[0037] Functional module 20 can integrate different functions, such as vacuuming, floor cleaning, inspection, and food delivery, and can then be paired with universal base 10 to form different types of service robots.

[0038] The floating quick-connect connector 30 includes a male connector 31 and a female connector 32. The male connector 31 has a conductive pin 312, and the female connector 32 has a conductive socket 321. When the male connector 31 and the female connector 32 are plugged into each other, the conductive pin 312 is inserted into the conductive socket 321, thus achieving a conductive connection between the two. The plugging direction of the male connector 31 and the female connector 32 is a first direction. One of the male connector 31 and the female connector 32 is floatingly disposed on one of the universal base 10 and the functional module 20, while the other is fixedly disposed on the other of the universal base 10 and the functional module 20. Specifically, the following scenarios are included: The male connector 31 is floatingly mounted on the universal base 10 and electrically connected to the universal base 10; the female connector 32 is fixedly mounted on the functional module 20 and electrically connected to the functional module 20; or, the male connector 31 is floatingly mounted on the functional module 20 and electrically connected to the functional module 20; the female connector 32 is fixedly mounted on the universal base 10 and electrically connected to the universal base 10; or, the male connector 31 is fixedly mounted on the universal base 10 and electrically connected to the universal base 10; the female connector 32 is floatingly mounted on the functional module 20 and electrically connected to the functional module 20; or, the male connector 31 is fixedly mounted on the functional module 20 and electrically connected to the functional module 20; the female connector 32 is floatingly mounted on the universal module and electrically connected to the universal module.

[0039] If both the female connector 32 and the male connector 31 are fixed to the corresponding universal base 10 or functional module 20, the male connector 31 and the female connector 32 may become misaligned or even suffer impact damage under vibration conditions. By setting the female connector 32 or the male connector 31 as a floating structure, and making the floating direction of the female connector 32 or the male connector 31 perpendicular to the first direction, the male connector 31 can move relative to the female connector 32 under vibration conditions. The position between the two can be adjusted according to the influence of vibration, and the conductive pin 312 and the conductive socket 321 always remain in a conductive state, without damaging the male connector 31 and the female connector 32.

[0040] The service robot in the above embodiment includes a universal base 10, a functional module 20, and a floating connector. One of the male connector end 31 and the female connector end 32 is floating, while the other is fixed. Since the male connector end 31 can float relative to the female connector end 32, when the service robot encounters a large threshold or groove, the functional module 20 may vibrate and displace relative to the universal base 10. The male connector end 31 can float relative to the female connector end 32 to adjust its relative position, so that the conductive pin 312 and the conductive socket 321 can always maintain close contact, so as to prevent the signal from being disconnected when the robot vibrates, and ensure a stable connection between the universal base 10 and the functional module 20.

[0041] Please refer to some embodiments of this utility model. Figure 3 and Figure 4 The male connector 31 is floatingly disposed on the universal base 10, and the female connector 32 is fixed to the functional module 20. The male connector 31 includes a male connector socket 311 floatingly disposed on the universal base 10, conductive pins 312 fixed to the male connector socket 311, and a connector 316 for connecting the male connector 31 and the universal base 10. The male connector 31 is electrically connected to the universal base 10, and the female connector 32 is electrically connected to the functional module 20. The male connector socket 311 is the basic structure of the male connector 31, and the conductive pins 312, etc., are disposed on the male connector socket 311. The male connector socket 311 can move relative to the universal base 10 in a direction perpendicular to a first direction, so that the entire male connector 31 can move relative to the universal base 10 in a direction perpendicular to the first direction. The connector 316 is used to float the male connector 31 to the universal base 10, so that the male connector 31 can float relative to the universal base 10.

[0042] By setting the connector 316, the male connector 31 is floatingly positioned on the universal base 10. When the functional module 20 and the universal base 10 are relatively displaced, the male connector 31 is displaced relative to the universal base 10 under the limiting effect of the female connector 32, so that the male connector 31 and the female connector 32 can always maintain a stable plugging state.

[0043] Please refer to some embodiments of this utility model. Figures 3 to 5The connector male base 311 has a first connection hole 3110, the universal base 10 has a second connection hole, and the connector 316 includes a screw. The screw passes through the first connection hole 3110 and is threaded into the second connection hole. The inner diameter of the first connection hole 3110 is larger than the major diameter of the screw. The first connecting hole 3110 is provided through the connector male socket 311. The first connecting hole 3110 is a through hole, and the second connecting hole is a threaded hole. The screw passes through the first connecting hole 3110 and is connected to the second connecting hole. If the inner diameter of the first connecting hole 3110 is compatible with the major diameter of the screw, the connector male socket 311 is fixedly connected to the universal base 10. The connector male socket 311 cannot move in the first direction and in the direction perpendicular to the first direction. If the inner diameter of the first connecting hole 3110 is larger than the major diameter of the screw, there is a gap between the inner wall of the first connecting hole 3110 and the outer peripheral wall of the screw. The screw can move in the direction perpendicular to the first direction. It can be understood that the connector male socket 311 can move relative to the universal base 10 in the radial direction of the first connecting hole 3110 to adjust the position of the connector male socket 311.

[0044] The connector male socket 311 is mounted on the universal base 10 by screws. The connection structure is simple, low-cost, and easy to assemble. Moreover, the inner diameter of the first connecting hole 3110 on the connector male socket 311 is larger than the outer diameter of the screw, which allows the connector male socket 311 to move in the radial direction relative to the universal base 10 in the first connecting hole 3110 to adjust the position of the connector male socket 311 and realize that the connector male socket 311 is floatingly set on the universal base 10.

[0045] The screw includes a head and a shank that are connected to each other. The shank is threaded. When the screw is installed on the connector male seat 311, the head of the screw abuts against the side of the connector male seat 311 away from the universal base 10.

[0046] In some embodiments, please refer to Figures 3 to 5 There are multiple connectors 316, and correspondingly, there are also multiple first connecting holes 3110 and second connecting holes. The number of connectors 316, first connecting holes 3110 and second connecting holes are the same, which can make the connector male socket 311 stably installed on the universal base 10.

[0047] Optionally, the number of connectors 316 is four, and the number of first connecting holes 3110 and second connecting holes is also four. The first connecting holes 3110 are respectively located at the four corners of the connector male socket 311.

[0048] Please refer to some embodiments of this utility model. Figure 3 and Figure 4The male connector 31 also includes a floating seat 314, which includes a cylindrical portion 3141 and two first skirt portions 3142. The two first skirt portions 3142 are formed by radially extending outward from both ends of the cylindrical portion 3141. The cylindrical portion 3141 is located inside the first connecting hole 3110, and the first skirt portions 3142 abut against the surface of the male connector 311 around the first connecting hole 3110. A screw is provided through the cylindrical portion 3141, and the outer peripheral wall of the cylindrical portion 3141 and the inner peripheral wall of the first connecting hole 3110 are spaced apart. The two first skirt portions 3142 are respectively connected to the opposite ends of the cylindrical portion 3141 in the axial direction, and the first skirt portions 3142 extend outward radially along the cylindrical portion 3141. The first skirt portion 3142 abuts against the surface of the connector male end 31 around the first connection hole 3110. The surface of the connector male socket 311 around the first connection hole 3110 is located on the side of the connector male end 31 away from and facing the universal base 10. One of the first skirt portions 3142 is located on the side of the connector male end 31 away from the universal base 10, and the other first skirt portion 3142 is located on the side of the connector male end 31 facing away from the universal base 10. After the floating seat 314 is installed to the connector male socket 311, the floating seat 314 is located between the inner peripheral wall of the first connection hole 3110 and the outer peripheral wall of the screw. The screw, the floating seat 314, and the universal base 10 remain relatively stationary. Under vibration conditions, the connector male socket 311 can move relative to the universal base 10.

[0049] The floating seat 314 isolates the screw from the first connecting hole 3110, preventing the screw from colliding with the inner wall of the first connecting hole 3110 and protecting the screw. Furthermore, the floating seat 314 has first skirt portions 3142 at both ends, which abut against the surface of the connector male seat 311, making the movement of the connector male seat 311 relative to the floating seat 314 smoother.

[0050] In some embodiments, the cylindrical portion 3141 of the floating seat 314 is matched to the size of the screw, such that after the screw passes through the cylindrical portion 3141, the cylindrical portion 3141 and the screw are relatively fixed. For example, the inner diameter of the cylindrical portion 3141 is smaller than the major diameter of the screw, and the two are configured with an interference fit. When the screw passes through the cylindrical portion 3141, it is equivalent to tapping the cylindrical portion 3141, thereby achieving relative fixation between the screw and the floating seat 314.

[0051] In some embodiments, the gap between the outer peripheral wall of the cylindrical portion 3141 and the inner peripheral wall of the first connecting hole 3110 is 0.15 mm to 0.2 mm. If the gap is too small, the floating distance of the connector male socket 311 is limited, and it cannot be guaranteed that the connector male end 31 and the connector female end 32 will always remain conductive; if the gap is too large, the locking force of the connector 316 on the connector male socket 311 is reduced, and even under non-vibration conditions, the connector male end 31 is prone to slippage.

[0052] Please refer to some embodiments of this utility model. Figure 3 and Figure 4 A nesting cylinder 315 is fixed to the inner peripheral wall of the first connecting hole 3110. A cylindrical portion 3141 is located inside the nesting cylinder 315, and there is a gap between the nesting cylinder 315 and the cylindrical portion 3141. The nesting cylinder 315 is fixedly connected to the connector male seat 311, and the nesting cylinder 315 moves synchronously when the connector male seat 311 floats. Because there is a gap between the nesting cylinder 315 and the cylindrical portion 3141, the connector male seat 311 and the nesting cylinder 315 can move relative to the universal base 10.

[0053] By setting the nested cylinder 315, the first connecting hole 3110 and the cylindrical part 3141 can be isolated to prevent the cylindrical part 3141 from colliding with the first connecting hole 3110, thereby protecting the first connecting hole 3110.

[0054] In some embodiments, the nesting cylinder 315 is a soft structure, which can mitigate the impact when the cylindrical portion 3141 collides with the nesting cylinder 315, so as to avoid damaging the male end 31 and the female end 32 of the connector.

[0055] Optionally, the nesting tube 315 is made of materials such as rubber or silicone.

[0056] In some embodiments, the nesting cylinder 315 is injection molded onto the inner wall of the first connecting hole 3110 using an insert molding process.

[0057] When installing the male connector 311, the nesting cylinder 315 is first injection molded into the inner wall of the first connecting hole 3110 through an insert molding process. The floating seat 314 is installed into the nesting cylinder 315 through a press-fit process. Finally, the connector 316 is passed through the floating seat 314 and connected to the universal base 10.

[0058] Please refer to some embodiments of this utility model. Figure 3 and Figure 4The gap between the inner peripheral wall of the nested cylinder 315 and the outer peripheral wall of the cylindrical portion 3141 is 0.15mm to 0.2mm. That is, the radial gap between the nested cylinder 315 and the cylindrical portion 3141 is 0.15mm to 0.2mm. When the connector male socket 311 floats relative to the universal base 10, the nested cylinder 315 moves relative to the cylindrical portion 3141. The gap setting allows the connector male socket 311 to float. If the gap is too small, the floating distance of the connector male socket 311 is limited, and it cannot be guaranteed that the connector male end 31 and the connector female end 32 will always maintain conductivity; if the gap is too large, the locking force of the connector 316 on the connector male socket 311 is reduced, and even under non-vibration conditions, the connector male end 31 is prone to slippage.

[0059] Optionally, the gap between the inner peripheral wall of the nested cylinder 315 and the outer peripheral wall of the cylindrical portion 3141 is 0.16 mm, 0.18 mm, 0.19 mm, etc.

[0060] Please refer to some embodiments of this utility model. Figure 3 and Figure 4 The axial ends of the nested cylinder 315 extend radially outward to form second skirt portions 3151. The connector male seat 311 has a recess 3111 around the first connecting hole 3110. The second skirt portions 3151 are located within the recess 3111, and the side of the second skirt portions 3151 facing away from the recess 3111 is flush with the surface of the connector male seat 311. There are two second skirt portions 3151, located at opposite ends of the axial direction of the nested cylinder 315. The location of the connector male seat 311 around the first connecting hole 3110 can be understood as the side of the connector male seat 311 facing the universal base 10 and the side facing away from the universal base 10. The two second skirt portions 3151 are located inside the two recesses 3111. The second skirt portion 3151 is flush with the surface of the connector male socket 311 on the side facing away from the recess 3111. The surface of the connector male socket 311 here can be understood as the side of the connector male socket 311 facing the universal base 10 and the side facing away from the universal base 10.

[0061] By providing a second skirt portion 3151 and a recess 3111, and placing the second skirt portion 3151 within the recess 3111, the nesting cylinder 315 can be axially limited, preventing it from falling off the connector male socket 311. Furthermore, the side of the second skirt portion 3151 facing away from the recess 3111 is flush with the surface of the connector male socket 311, making the surface of the connector male socket 311 smoother, thus allowing for smoother movement of the connector male socket 311 relative to the universal base 10.

[0062] Please refer to some embodiments of this utility model. Figure 5 and Figure 6One of the male connector end 31 and the female connector end 32 is provided with a guide post 317, and the other is provided with a guide hole 323. When the male connector end 31 and the female connector end 32 approach each other, the guide post 317 gradually extends into the guide hole 323, aligning the male connector end 31 and the female connector end 32, thereby allowing the conductive pin 312 to be gradually inserted into the conductive socket 321.

[0063] By setting the guide post 317 and the guide hole 323, the male end 31 and the female end 32 of the connector can be guided and inserted, so that the male end 31 and the female end 32 of the connector can be aligned with each other.

[0064] In some embodiments, the guide post 317 is fixedly disposed on the male connector seat 311, and the guide hole 323 is formed on the female connector end 32.

[0065] In some embodiments, the guide post 317 is fixedly disposed on the female end 32 of the connector, and the guide hole 323 is formed in the male connector 311.

[0066] In some embodiments, the top end of the guide post 317 is conical, making it easier for the guide post 317 to enter the guide hole 323.

[0067] In some embodiments, there are multiple guide posts 317 and guide holes 323, and the guide posts 317 and guide holes 323 are arranged in a one-to-one correspondence.

[0068] Please refer to some embodiments of this utility model. Figure 7 The circumferential inner wall of the conductive socket 321 has a torsion spring 324 for contacting and conducting with the conductive pin 312. When the conductive pin 312 is inserted into the conductive socket 321, the outer circumferential wall of the conductive pin 312 abuts against the inner circumferential wall of the torsion spring 324, thereby making the male end 31 and the female end 32 of the connector conductively connected. Specifically, the conductive pin 312 compresses the torsion spring 324, the torsion spring 324 deforms, and the rebound force of the torsion spring 324 presses firmly against the conductive pin 312, making the conductive connection between the two more stable.

[0069] In conventional solutions, conductive springs and guiding structures are used to provide power and control signals to the functional module 20. However, the number and area of ​​the conductive spring contacts are relatively small, and the contacts are prone to oxidation and failure due to overcurrent and temperature rise. Therefore, to ensure sufficient current, the springs need to be very large, resulting in a large footprint. This embodiment, by incorporating a torsion spring 324 inside the conductive socket 321, increases the conductive contact area, ensuring reliable connection and low contact resistance. It also provides strong overcurrent capability and meets automotive-grade shock resistance requirements, satisfying the robot's usage needs.

[0070] Please refer to some embodiments of this utility model. Figure 5 and Figure 6 The male connector 31 also includes a plurality of first conductive contacts 313, and the female connector 32 also includes a plurality of second conductive contacts 322 that correspond one-to-one with the first conductive contacts 313. The first conductive contacts 313 may be arranged in a linear pattern, a rectangular array, a ring array, etc.

[0071] When the functional module 20 is connected to the universal base 10, the universal base 10 provides power to the functional module 20 and transmits control signals. The conductive pin 312 and conductive socket 321 provide power to the functional module 20, and the conductive contact 313 and the second conductive contact 322 transmit control signals to the functional module 20.

[0072] In some embodiments of this invention, the service robot further includes a guide rail structure comprising cooperating guide recesses and guide protrusions. The cross-section of the guide protrusion gradually increases from its top to its base. The guide recess is located in one of the universal base 10 and the functional module 20, and the guide protrusion is located in the other of the universal base 10 and the functional module 20. When the functional module 20 is mounted onto the universal base 10, the guide protrusion gradually extends into the interior of the guide recess. The cross-section of the guide protrusion gradually increases from its top to its base, and correspondingly, the cross-section of the guide recess gradually decreases from its top to its base, making the guide recess flared.

[0073] By setting guide recesses and guide protrusions, the universal base 10 and the functional module 20 can be more easily assembled together.

[0074] In some embodiments, a guide protrusion is provided on the universal base 10, and a guide recess is provided on the functional module 20.

[0075] In some embodiments, guide protrusions are provided on the functional module 20, and guide recesses are provided on the universal base 10.

[0076] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
