Description

Technical Field

[0001] This utility model relates to the field of toy vehicle technology, specifically to a seat status indicator device and a seat. Background Technology

[0002] Proper installation and use of the seat are crucial for ensuring passenger safety. The seat consists of the seat body and the base, with the seat body installed onto the base.

[0003] Currently, although some seats have status indicator functions, they can only indicate the overall engagement status of the seat body and the base, and cannot distinguish the engagement status of different parts (such as the front and rear, left and right). If a part is not engaged, the user will not be able to notice it, creating a safety blind spot. In the event of an accident, the unengaged part may cause the seat to become unstable, increasing the risk of injury. Especially during sudden braking or collision, local loosening will weaken the overall protection effect and create a safety hazard. Utility Model Content

[0004] In view of this, the present invention provides a seat status indicator device and a seat to solve the problem that current seats can only indicate the overall engagement status of the seat body and the base, and cannot distinguish the engagement status of different parts.

[0005] In a first aspect, this utility model provides a seat status indicator device, applicable to a seat having a seat body and a base, comprising: At least two sets of indicator windows are respectively set at different connection positions of the base; At least two sets of seat indicator mechanisms are respectively arranged at each of the indicator window positions. Each seat indicator mechanism has a first indicator position and a second indicator position. When the seat body is connected to the base, the first indicator position is facing the indicator window. When the seat body is disconnected from the base, the second indicator position is facing the indicator window.

[0006] The beneficial effects of the aforementioned seat status indicator device are as follows: By setting at least two sets of independent indicator windows and corresponding seat indicator mechanisms, it achieves separate indication of the engagement status of different parts (such as the front and rear, left and right, etc.) of the seat body and the base. Users can intuitively judge the connection status of the corresponding position through each indicator window, effectively eliminating the safety blind spots that traditional integral indicators cannot distinguish between partially engaged parts. This ensures that all key parts are in the correct connection state during installation, significantly improving the accuracy and reliability of seat installation, reducing the safety risks of passenger safety caused by partial loosening, and better protecting personnel safety.

[0007] In one optional embodiment, the seat indicator mechanism is provided in two groups, namely a first indicator mechanism group and a second indicator mechanism group, which are distributed at intervals along the front-back direction or the left-right direction; each first indicator mechanism group includes at least one first indicator mechanism, and each second indicator mechanism group includes at least one second indicator mechanism.

[0008] In one optional implementation, the first indicating mechanism includes: The first color-changing rotating component is rotatably mounted on the base; A first trigger component is disposed on the seat body and corresponds to the first color-changing rotating component.

A first reset component is disposed on the base and connected to the first color-changing rotating component. When the seat body is disconnected from the base, the first reset component drives the first color-changing rotating component to reset.

[0009] The beneficial effects of the above technical solution are as follows: the first indicator mechanism presses the first color-changing rotating component on the base through the first trigger component on the seat body to realize the color indicator switching. Combined with the first reset component driving the first color-changing rotating component to reset when the seat is removed, it not only realizes the accurate and intuitive feedback of the installation status of each part, but also eliminates the safety blind spot of the existing technology that can only indicate the whole, and avoids the risk of seat displacement caused by partial non-locking.

[0010] In one optional implementation, the first color-changing rotating assembly includes: A rotating plate extends from the top of the base at one end and is rotatably mounted on the base via a first rotating shaft at the other end. A positioning block is connected to a first rotating shaft. A first color display block is provided on the wall surface of the positioning block facing the indicator window. The first color display block has at least two color indicator areas.

[0011] The beneficial effects of the above technical solution are as follows: The first color-changing rotating component, through the linkage design of the rotating plate and the positioning block, combined with the multi-color indicator area of ​​the first color display block, realizes the mechanically triggered precise color switching of the seat connection status. The first shaft connection structure between the rotating plate and the base ensures smooth rotation and stable positioning. The first color display block on the positioning block can intuitively reflect the seat installation status through color changes. Users can quickly identify the engagement status of the corresponding parts through the indicator window, improving the accuracy and reliability of the status indication.

[0012] In one optional embodiment, the first triggering component is a pressing shaft disposed on the seat body. When the seat body is connected to the base, the pressing shaft presses against a rotating piece extending from the top of the base to drive the positioning block to rotate via the first rotating shaft. And / or, the first reset component is disposed between the positioning block and the inner wall of the base; And / or, the base is provided with at least one hook, and the top end of the rotating piece extends into the hook groove position when not pressed.

[0013] In one optional implementation, the second indicating mechanism includes: The second color-changing rotating component is rotatably mounted on the base; The second trigger component is disposed on the seat body and corresponds to the second color-changing rotating component. When the seat body is connected to the base, the second trigger component presses the second color-changing rotating component to rotate, so as to switch the first indication position and the second indication position. The second reset component is disposed on the base and connected to the second color-changing rotating component. When the seat body is disconnected from the base, the second trigger component drives the second color-changing rotating component to reset.

[0014] The beneficial effects of the above technical solution are as follows: the second indicator mechanism achieves accurate switching and reliable reset of the indicator state during seat installation and removal through the mechanical linkage between the second trigger component and the second color-changing rotation component and the automatic rebound design of the second reset component.

[0015] In one optional embodiment, the second color-changing rotating assembly includes a rotating disk rotatably mounted on the base, a second color display block being provided on the wall surface of the rotating disk facing the indicator window, the second color display block having at least two color indicator areas, and an abutment groove adapted to the second trigger assembly being provided on the wall surface of the rotating disk facing the second trigger assembly; the second reset assembly is a spring piece inclinedly mounted on the rotating disk. And / or, the second triggering component includes a push rod, a first fixing member, a second fixing member, and a third fixing member. The first fixing member, the second fixing member, and the third fixing member are respectively provided with slide rails. The push rod is slidably disposed on the slide rails. One end of the push rod corresponds to the second color-changing rotating component, and the other end of the push rod is connected to the inner wall of the base through a return spring.

[0016] Secondly, this utility model provides a seat, comprising: The base has a positioning groove at its bottom; The seat body is detachably mounted on the base; The support feet are rotatably mounted in the positioning grooves of the base; The aforementioned seat status indicator device.

[0017] In one alternative implementation, the support leg includes: The first tube has a hollow interior and is pivotally connected to the base via a supporting foot cover. The second tube is slidably fitted into the first tube and its extension and retraction are adjusted within the first tube via an adjusting component.

[0018] The beneficial effects of the above technical solution are as follows: the adjustable components can precisely lock the telescopic length to meet the support needs of different ground heights or usage scenarios, and improve the stability of the device placement. The pivot structure allows the support legs to be flexibly extended or retracted, saving storage space when retracted, and ensuring stable support angle through mechanical limiting when extended.

[0019] In one optional embodiment, the supporting foot cover is rotatably mounted on a supporting foot cover rotation shaft, and both ends of the supporting foot cover rotation shaft are fixedly mounted on a base; a third color display block is provided on the outer side wall of the supporting foot cover, the third color display block having at least two color indication areas, and the indication window on the base corresponds to the color indication area of ​​the third color display block.

[0020] The beneficial effects of the above technical solution are as follows: the multi-color area of ​​the third color block on the outer side wall of the support foot cover, together with the base indicator window, can intuitively reflect the real-time status of the support foot (such as red when folded up and green when unfolded). The working status of the support foot can be accurately conveyed through color changes without additional operation, thereby improving the user's efficiency in judging the stability of the device.

[0021] In one optional embodiment, the adjustment assembly includes a support foot fixing seat, a fixing pin, and a button.

The support foot fixing seat is rotatably mounted on the button via a button shaft. At least one fixing pin is provided on the side of the button near the second tube. A pressing part is provided on the side of the button away from the second tube. The fixing pin and the pressing part are located on opposite sides of the button shaft.

[0022] The beneficial effects of the above technical solution are as follows: The adjustment component realizes the rapid adjustment and stable locking of the support foot height through the lever linkage design of the button, the fixing pin and the pin hole: When the button is pressed, the fixing pin is driven to disengage from the pin hole based on the lever principle, so the extension length of the second tube can be flexibly adjusted. After being released, the fixing pin automatically engages with the corresponding pin hole under its own elastic force (or structural restoring force), thus completing the multi-level height locking. The operation is convenient and the adjustment accuracy is high.

[0023] In one optional embodiment, a mounting base is provided at the end of the second tube away from the support foot cover, a support foot indicator is rotatably connected to the mounting base, a fourth reset member is provided between the support foot indicator and the mounting base, a fourth color block is provided on the support foot indicator, the fourth color block has at least two color indication areas, and a fourth indicator window corresponding to the fourth color block is provided on the mounting base.

[0024] The beneficial effects of the above technical solution are as follows: The support foot indicator, through its rotating connection design with the mounting base, combined with the corresponding coordination between the multi-color indicator area of ​​the fourth color block and the fourth indicator window, achieves real-time visual feedback on the support foot's ground contact status: When the support foot is extended and in contact with the ground, the support foot indicator rotates under the pressure of external force, aligning the corresponding color area of ​​the fourth color block with the window (e.g., green indicates support in place). When the support foot indicator is retracted, it rotates to reset and displays another color (e.g., red indicates no support). The support status can be intuitively judged without additional operation, improving the user's efficiency in confirming the stability of the device. Attached Figure Description

[0028] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0029] According to an embodiment of the present invention, in a first aspect, a seat status indicator device is provided, combined with... Figures 1 to 18 As shown, this invention is applicable to a seat having a seat body 1 and a base 2, and includes an indicator window 3 and a seat indicator mechanism. At least two sets of indicator windows 3 are provided, each located at a different connection position on the base 2, where the connection position of the base 2 refers to the connection position between the base 2 and the seat body 1. At least two sets of seat indicator mechanisms are provided, each corresponding to a position on the indicator window 3. Each seat indicator mechanism has a first indicator position and a second indicator position. When the seat body 1 is connected to the base 2, the first indicator position faces the indicator window 3; when the seat body 1 is disconnected from the base 2, the second indicator position faces the indicator window 3.

[0030] The aforementioned seat status indicator device, by setting at least two sets of independent indicator windows 3 and corresponding seat indicator mechanisms, enables separate indication of the engagement status of different parts (such as the front and rear, left and right sides) of the seat body 1 and the base 2. Users can intuitively judge the connection status of the corresponding position through each indicator window 3, effectively eliminating the safety blind spots that traditional integral indicators cannot distinguish between partially engaged parts. This ensures that all key parts are in the correct connection state during installation, significantly improving the accuracy and reliability of seat installation, reducing the safety risks of passenger safety caused by partial loosening, and better protecting personnel safety.

[0031] The segmented indicator design allows users to make targeted adjustments during installation. For example, if the rear part is not properly engaged, users can focus on checking the rear part to avoid repeated disassembly and reassembly errors. At the same time, clear status feedback reduces installation failures caused by improper operation, improving the overall user experience.

[0032] The aforementioned seat status indicator can be applied to child seats to monitor the installation status of child safety seats, and can also be applied to other seat scenarios.

[0033] In some embodiments, the seat indicator mechanism comprises two groups: a first indicator group and a second indicator group, which are spaced apart along the front-to-back or left-to-right direction. Each first indicator group includes at least one first indicator 4, which can be distributed at different positions on the seat body 1 and the base 2. For example, when two first indicator 4s are provided, they are respectively located on the left and right sides of the seat body 1 and the base 2, used to indicate the installation position on the left and right sides of the seat body 1 and the base 2. Each second indicator group includes at least one second indicator 5, which can be distributed at different positions on the seat body 1 and the base 2. For example, when two second indicator 5s are provided, they are respectively located on the left and right sides of the seat body 1 and the base 2, used to indicate the installation position on the left and right sides of the seat body 1 and the base 2.

[0034] In some embodiments, the first indicating mechanism 4 includes a first color-changing rotation component 41, a first trigger component 42, and a first reset component 415. The first color-changing rotation component 41 is rotatably mounted on the base 2 and is used to change color during rotation. The first trigger component 42 is mounted on the seat body 1 and corresponds to the first color-changing rotation component 41. When the seat body 1 is connected to the base 2, the first trigger component 42 presses the first color-changing rotation component 41 to rotate, thereby switching between a first indicating position and a second indicating position. The first reset component 415 is mounted on the base 2 and connected to the first color-changing rotation component 41. When the seat body 1 is disconnected from the base 2, the first reset component 415 drives the first color-changing rotation component 41 to reset.

[0035] The first indicator mechanism 4 of the seat status indicator device switches the color indication by pressing the first color-changing rotating component on the base 2 through the first trigger component 42 on the seat body 1. Combined with the first reset component 415 driving the first color-changing rotating component 41 to reset when the seat is removed, it not only realizes accurate and intuitive feedback on the installation status of each part, but also eliminates the safety blind spot of the existing technology that can only indicate the whole, and avoids the risk of seat displacement caused by partial misalignment.

[0036] More specifically, combined Figure 7As shown, the first color-changing rotating assembly 41 includes a rotating plate 411 and a positioning block 413. One end of the rotating plate 411 extends from the top of the base 2, and the other end of the rotating plate 411 is rotatably mounted on the base 2 via a first rotating shaft 412. The positioning block 413 is connected to the first rotating shaft 412, and a first color display block 414 is provided on the wall surface of the positioning block 413 facing the first indicator window 31. The first color display block 414 has at least two color indicator areas, wherein one color in the color indicator area corresponds to a first indicator position, and the other color in the color indicator area corresponds to a second indicator position.

[0037] In this embodiment, the first color-changing rotating assembly 41, through the linkage design of the rotating plate 411 and the positioning block 413, combined with the multi-color indicator area of ​​the first color display block 414, realizes the mechanically triggered precise color switching of the seat connection status. The connection structure between the rotating plate 411 and the first rotating shaft 412 of the base ensures smooth rotation and stable positioning. The first color display block 414 on the positioning block 413 can intuitively reflect the seat installation status through color changes. Users can quickly identify the engagement status of the corresponding parts through the indicator window, improving the accuracy and reliability of the status indication. When the seat body 1 is connected to the base 2, the first trigger component 42 presses the rotating plate 411, thereby causing the rotating plate 411 to rotate, which in turn causes the first color display block 414 on the positioning block 413 to rotate, so that the first indicator mechanism 4 moves to the first position. The user can quickly determine that the seat body 1 and the base 2 are connected by the first color (e.g., green) presented by the first indicator mechanism 4. When the seat body 1 and the base 2 are separated, the rotating plate 411 and the first color display block 414 on the positioning block 413 are reset, so that the first indicator mechanism 4 moves to the second position. The user can quickly determine that the seat body 1 and the base 2 are separated by the second color (e.g., red) presented by the first indicator mechanism 4.

[0038] Combination Figure 6 As shown, the first trigger component 42 is a pressing shaft mounted on the seat body 1. When the seat body 1 is connected to the base 2, the pressing shaft presses against the rotating plate 411 extending from the top of the base 2, thereby driving the positioning block 413 to rotate via the first rotating shaft 412. In this embodiment, the first trigger component 42 achieves instantaneous response to seat installation actions and indicator state switching through the direct mechanical linkage between the pressing shaft on the seat body 1 and the rotating plate 411. The pressing shaft naturally presses against the rotating plate 411 during the connection process of the seat body 1, and precisely drives the positioning block 413 to rotate via the first rotating shaft 412, without the need for additional manual operation. The mechanical trigger structure has high stability and is not easily affected by environmental factors, ensuring the accuracy and reliability of state switching. At the same time, it is directly integrated into the connection action between the seat body 1 and the base 2, so that the triggering process and the installation operation are completed synchronously, improving the overall coordination and ease of use of the device.

[0039] Combination Figure 3 and Figure 4 As shown, to facilitate the positioning of the pressing shaft when it contacts the rotating plate 411, the base 2 is provided with at least one hook 43. When the top of the rotating plate 411 is not pressed, it extends into the hook groove of the hook 43. When the seat body 1 is connected to the base 2, the pressing shaft can be embedded in the hook groove of the hook 43 and press the top of the rotating plate 411.

[0040] The first reset component 415 is disposed between the positioning block 413 and the inner wall of the base 2. The first reset component 415 is a spring.

[0041] In some embodiments, the second indicating mechanism 5 includes a second color-changing rotation component 51, a second trigger component 52, and a second reset component 512. The second color-changing rotation component 51 is rotatably mounted on the base 2. The second trigger component 52 is mounted on the seat body 1 and corresponds to the second color-changing rotation component 51. When the seat body 1 is connected to the base 2, the second trigger component 52 presses the second color-changing rotation component 51 to rotate, thereby switching between the first indicating position and the second indicating position. The second reset component 512 is mounted on the base 2 and connected to the second color-changing rotation component 51. When the seat body 1 is disconnected from the base 2, the second trigger component 52 drives the second color-changing rotation component 51 to reset.

[0042] In this embodiment, the second indicating mechanism 5 achieves precise switching and reliable reset of the indicating state during seat installation and removal through the mechanical linkage between the second trigger component 52 and the second color-changing rotation component 51, and the automatic springback design of the second reset component 512. When the seat body 1 is connected to the base 2, the second trigger component 52 drives the second color-changing rotation component 51 to switch to the first indicating position through a pressing action, providing intuitive feedback on the installation status. When the seat body 1 is removed from the base 2, the second reset component 512 independently drives the second color-changing rotation component 51 to spring back to the second indicating position, ensuring that the status indication is strictly synchronized with the actual connection status. This structure requires no additional energy drive and achieves fully automatic state switching through pure mechanical transmission, improving the timeliness and accuracy of the indication response. At the same time, the setting of the second reset component 512 avoids the risk of misjudgment due to the indication status remaining after disassembly, further strengthening the safety redundancy of independent monitoring of multiple parts and ensuring that the user has comprehensive control over the status of each key connection point of the seat.

[0043] More specifically, combined Figure 8 and Figure 9As shown, the second color-changing rotating assembly 51 includes a rotating disk 511, which is rotatably mounted on the base 2 via a second rotating shaft 513. A second color display block 514 is provided on the wall surface of the rotating disk 511 facing the second indicator window 32. The second color display block 514 has at least two color indicator areas, wherein one color in the color indicator area corresponds to a first indicator position, and the other color in the color indicator area corresponds to a second indicator position. An abutment groove 5111 adapted to the second trigger assembly 52 is provided on the wall surface of the rotating disk 511 facing the second trigger assembly 52. ​​The second reset assembly 512 is a spring piece inclined on the rotating disk 511.

[0044] Combination Figure 10 and Figure 11 As shown, the second trigger assembly 52 includes a push rod 521, a first fixing member 522, a second fixing member 523, and a third fixing member 524. Each of the first fixing member 522, the second fixing member 523, and the third fixing member 524 has a slide rail. The push rod 521 is slidably mounted on the slide rail. One end of the push rod 521 corresponds to the second color-changing rotation assembly 51, and the other end of the push rod 521 is connected to the inner wall of the base 2 via a return spring 525. Figure 12 As shown. The first fixing member 522, the second fixing member 523, and the third fixing member 524 are provided to prevent the push rod 521 from wobbling left and right.

[0045] In this embodiment, the combined design of the second color-changing rotating component 51 and the second triggering component 52 achieves a highly efficient and reliable status indication function through multiple mechanical structural optimizations. The precise fit between the abutment groove 5111 of the rotating disk 511 and the push rod 521 ensures the directional transmission of the triggering action. Combined with the sliding limit of the first fixing member 522, the second fixing member 523, and the third fixing member 524, it effectively prevents the push rod from wobbling left and right during sliding, improving the accuracy of the trigger position and the stability of the movement. When the seat body 1 is disengaged from the base 2, the return spring 525 at the tail of the push rod 521 can reset the push rod 521, and the spring on the rotating disk 511 can reset the rotating disk 511. The return spring 525 at the tail of the push rod 521 and the spring on the rotating disk 511 form a dual elastic reset mechanism, ensuring stable pushing force output from the push rod to the rotating disk during seat installation and enabling rapid reset through dual elasticity after disassembly, avoiding delays or stagnation in status indication. The multi-color area of ​​the second color display block, in conjunction with the indicator window, allows for intuitive differentiation of different connection states.

[0046] When the seat body 1 is connected to the base 2, the push rod 521 abuts against the abutment groove 5111 on the rotating disk 511, thereby driving the rotating disk 511 to rotate, causing the second indicator mechanism 5 to move to the first position. The user can quickly determine that the seat body 1 and the base 2 are connected at this time by the third color (e.g., green) presented by the second indicator mechanism 5. When the seat body 1 and the base 2 are separated, the rotating disk 511 is reset under the action of the spring, causing the second indicator mechanism 5 to move to the second position. The user can quickly determine that the seat body 1 and the base 2 are separated at this time by the fourth color (e.g., red) presented by the second indicator mechanism 5.

[0047] According to an embodiment of the present invention, in a second aspect, a seat is provided, including a base 2, a seat body 1, support legs 6, and a seat status indicator device. A positioning groove is provided at the bottom of the base 2. The seat body 1 is detachably mounted on the base 2. Figure 14 As shown, the support foot 6 is rotatably mounted in the positioning groove of the base 2.

[0048] In some embodiments, the support foot includes a first tube 61 and a second tube 62. The first tube 61 is hollow inside and is pivotally connected to the base 2 via a support foot cover 68. The hollow first tube 61 provides a stable sliding track for the second tube 62, which is slidably fitted inside the first tube 61 and can be extended or retracted within the first tube 61 by an adjustment component. In this embodiment, the adjustment component can precisely lock the extension length to meet the support needs of different ground heights or usage scenarios, improving the stability of the device placement. The pivot structure allows the support foot to be flexibly extended or retracted; when retracted, it saves storage space, and when extended, mechanical limiting ensures a stable support angle.

[0049] In some embodiments, combined with Figure 15 As shown, the support foot cover 68 is rotatably mounted on the support foot cover rotation shaft 69, and both ends of the support foot cover rotation shaft 69 are fixedly mounted on the base 2; a third color display block 67 is provided on the outer wall of the support foot cover 68, the third color display block 67 has at least two color indicator areas, wherein one color in the color indicator area corresponds to a first indicator position, and the other color in the color indicator area corresponds to a second indicator position. Combined with... Figure 2 As shown, the third indicator window 33 on the base 2 corresponds to the color indicator area of ​​the third color block 67.

[0050] In this embodiment, the multi-color area of ​​the third color block 67 on the outer side wall of the support foot cover 68, together with the base indicator window, can intuitively reflect the real-time status of the support foot (e.g., red when folded up, green when unfolded). The working status of the support foot can be accurately conveyed through color changes without additional operation, improving the user's efficiency in judging the stability of the device.

[0051] In some embodiments, combined with Figure 17 and Figure 18 As shown, the adjustment assembly includes a support foot fixing seat 63, a fixing pin 65, and a button 64. Multiple pin holes 621 are provided on the wall of the second tube 62 along its extension direction. The support foot fixing seat 63 is sleeved on the outside of the first tube 61. The button 64 is rotatably mounted on the support foot fixing seat 63 via a button shaft 642. At least one fixing pin 65 is provided on the side of the button 64 near the second tube 62, and a pressing part 641 is provided on the side of the button 64 away from the second tube 62. The fixing pin 65 and the pressing part 641 are located on both sides of the button shaft 642.

[0052] In this embodiment, the adjustment component achieves rapid adjustment and stable locking of the support foot height through a lever-type linkage design of button 64, fixing pin 65, and pin hole: when button 64 is pressed, the fixing pin 65 is driven to disengage from the pin hole based on the lever principle, thereby flexibly adjusting the extension length of the second tube 62; after being released, the fixing pin 65 automatically engages with the corresponding pin hole under its own elastic force (or structural restoring force), completing multi-level height locking, which is convenient to operate and has high adjustment accuracy. The support foot fixing seat 63 enhances the overall structural rigidity by wrapping the first tube, and the ergonomic design of the button pivot and pressing part improves the operating feel and force application efficiency.

[0053] In some embodiments, a mounting base 611 is provided at the end of the second tube 62 away from the support foot cover 68. The mounting base 611 is inserted into the interior of the second tube 62 and sealed by the cover plate 612. A support foot indicator 610 is rotatably connected to the mounting base 611. A fourth reset member, which is a torsion spring, is provided between the support foot indicator 610 and the mounting base 611. Figure 16 and Figure 18 As shown, the support foot indicator 610 is provided with a fourth color block 6101, which has at least two color indication areas, and the mounting base 611 is provided with a fourth indicator window 34 corresponding to the fourth color block 6101.

[0054] In this embodiment, the support foot indicator 610, through its rotatable connection design with the mounting base, combined with the corresponding cooperation between the multi-color indicator area of ​​the fourth color block 6101 and the fourth indicator window 34, achieves real-time visual feedback on the support foot's ground contact status: when the support foot is extended and in contact with the ground, the support foot indicator 610 rotates under the action of external force, aligning the corresponding color area of ​​the fourth color block 6101 with the window (e.g., green indicates support in place); when the support foot indicator 610 is retracted, it resets by rotation to display another color (e.g., red indicates no support). The support status can be intuitively judged without additional operation, improving the user's efficiency in confirming the stability of the device.

[0055] Furthermore, the mounting base 611 is provided with a receiving groove. When the support foot indicator 610 is squeezed, the support foot indicator 610 is received by the receiving groove, so that the mounting base 611 comes into contact with the outside. The contact surface between the mounting base 611 and the outside is a flat surface, thereby ensuring the stability of the support foot when it is unfolded and in contact with the outside.

[0056] Although embodiments of the present invention have been described in conjunction with the accompanying drawings, those skilled in the art can make various modifications and variations without departing from the spirit and scope of the present invention, and such modifications and variations all fall within the scope defined by the appended claims.
