Description

Technical Field

[0001] This invention relates to the field of child car seat technology, and in particular to a support mechanism and a safety seat. Background Technology

[0002] To prevent child safety seats from shifting due to inertia during sudden braking or other emergencies, a support leg is typically installed at the front of the base. This support leg can be adjusted in length to align with the vehicle floor, thus supporting and securing the safety seat. However, users often rely solely on feel and experience to adjust the support leg's height, making it difficult to determine whether the support leg is properly in contact with the floor and thus ensuring it is correctly installed. Summary of the Invention

[0003] The present invention aims to at least solve one of the technical problems existing in the prior art. To this end, the present invention proposes a support mechanism and a safety seat capable of indicating whether the support mechanism is properly installed.

[0004] According to a first aspect of the present invention, a support mechanism is provided, comprising: an outer tube, an inner tube, a display component, a locking component, and a stop member. The outer tube has a cavity extending vertically inside and a through groove communicating with the cavity on its outer surface. The inner tube passes through the cavity and is slidably connected to the outer tube. The inner tube has a plurality of locking holes spaced apart vertically, and a limiting portion is provided at the top end of the inner tube. The display component is mounted on the outer tube and includes an identifier and a driving component connected to each other. The identifier has a first identifier and a second identifier, and the driving component is capable of moving vertically to rotate the identifier. The locking component includes a locking member and a connecting member. The locking member can pass through the through groove and connect with the outer tube. The connector is engaged with one of the aforementioned slots. One end of the connector is connected to the locking member, and the other end is connected to the driving member. The stopping member includes a stopping part, which passes through the bottom opening of the outer tube and is fixedly connected to the outer tube. The stopping part can abut against the limiting part to stop the inner tube. The inner tube has a supported state and a non-supported state. When the inner tube is in the non-supported state, the marking member displays the first marking. When the inner tube is in the supported state, the bottom end of the inner tube abuts against the vehicle floor. The inner tube can drive the locking member to move upward along the through groove through the slot and drive the connector to move upward, thereby driving the driving member to move upward and causing the marking member to rotate. The marking member displays the second marking.

[0005] A locking component according to an embodiment of the present invention has at least the following beneficial effects:

[0006] This invention achieves height adjustment of the support mechanism through a sliding connection between the outer and inner tubes. The use of a stop and a limiting part prevents the inner tube from detaching from the outer tube. The height of the support mechanism is fixed by the locking member engaging with one of the locking holes. A display component is included so that when the inner tube is in a non-supported state, the indicator displays a first indicator. When the bottom end of the inner tube abuts against the vehicle floor, it is in a supported state. The inner tube can then drive the locking member upwards along the through groove via the locking hole, simultaneously driving the connecting member upwards. The upward movement of the connecting member drives the driving member upwards, which in turn rotates the indicator, causing it to display a second indicator. By displaying either the first or second indicator, the user can clearly determine whether the support mechanism is in a supported state. This facilitates the user's understanding of whether the support mechanism is fully in contact with the floor, thus confirming that the support legs are properly installed. This not only reduces the time required for installation, improves installation efficiency and difficulty, but also enhances installation accuracy, stability, and reliability, significantly improving the user experience.

[0041] Embodiments of the present invention are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0042] In the description of this invention, it should be understood that the orientation descriptions, such as up, down, inside, outside, etc., are based on the orientation or positional relationship shown in the drawings and are only for the convenience of describing this invention and simplifying the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this invention.

[0043] In the description of this invention, the use of "first" and "second" is for the purpose of distinguishing technical features only, and should not be construed as indicating or implying relative importance or implicitly indicating the number of technical features indicated or the order of the technical features indicated.

[0044] In the description of the present invention, unless otherwise clearly defined, terms such as setting, installing, and connecting should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in the present invention based on the specific content of the technical solution.

[0045] To prevent child safety seats from shifting due to inertia during sudden braking or other emergencies, a support leg is typically installed at the front of the base. This support leg can be adjusted in length to align with the vehicle floor, thus supporting and securing the safety seat. However, users often rely solely on feel and experience to adjust the support leg's height, making it difficult to determine whether the support leg is properly in contact with the floor and thus ensuring it is correctly installed.

[0046] Therefore, some embodiments of the present invention provide a support mechanism 1000, as detailed in the accompanying drawings. Figures 1-9 As shown.

[0047] Reference Figure 1 , Figure 2 and Figure 4As shown, in this embodiment of the invention, the support mechanism 1000 may include: an outer tube 100, an inner tube 200, a display component 300, a locking component 400, and a stop component 500. The outer tube 100 may have a cavity 110 extending vertically inside, the size and shape of which match the inner tube 200. The outer tube 100 has a through groove 120 communicating with the cavity 110 on its exterior. It should be noted that the end of the support mechanism 1000 facing the vehicle floor is the lower end, and the end away from the vehicle floor is the upper end. The extending direction of the inner tube 200 may be consistent with the extending direction of the cavity 110. Therefore, the inner tube 200 can pass through the cavity 110 and slide connected to the outer tube 100. The relative sliding between the inner tube 200 and the outer tube 100 enables the height of the support mechanism 1000 to be adjustable. The inner tube 200 may have multiple locking holes 210, which are spaced apart vertically. Specifically, refer to... Figure 6 , Figure 7 and Figure 9 As shown, the through groove 120 can be connected to any of the slots 210. It should be noted that the length of the through groove 120 in the vertical direction is greater than the length of the slot 210 in the vertical direction.

[0048] Reference Figure 2 , Figure 3 and Figure 5 As shown, in this embodiment of the invention, the display component 300 can be installed on the outer tube 100. Specifically, the display component 300 can be detachably connected to the outer tube 100, or it can be slidably connected, allowing the display component 300 to move up and down along the outer tube 100. This embodiment does not limit this. The display component 300 may include an identifier 310 and a driving component 320 connected to each other. It should be noted that the identifier 310 and the driving component 320 can be directly connected, or they can be indirectly connected through other components. This embodiment does not limit this. The identifier 310 may be provided with a first identifier 311 and a second identifier 312. The identifier 310 showing the first identifier 311 can indicate that the inner tube 200 is in a non-supported state, and the identifier 310 showing the second identifier 312 can indicate that the inner tube 200 is in a supported state. The first identifier 311 and the second identifier 312 can be visual identifiers. For example, the first identifier 311 can be a red sticker, and the second identifier 312 can be a green sticker. The first identifier 311 and the second identifier 312 can also be other types of visual identifiers. Those skilled in the art can choose to set them according to the actual situation, and this embodiment does not limit them. Refer to Figure 5 and Figure 8 As shown, the drive unit 320 can move up and down to drive the marker 310 to rotate. When the marker 310 rotates, it can switch the position of the first marker 311 and the second marker 312, thereby displaying the first marker 311 or the second marker 312.

[0049] Reference Figure 4 , Figure 6 and Figure 7 As shown, in this embodiment of the invention, the locking assembly 400 may include a locking member 410 and a connecting member 420. It is understood that when the inner tube 200 can slide relative to the outer tube 100, the inner tube 200 is in an active state; when the inner tube 200 cannot slide relative to the outer tube 100, the inner tube 200 is in a locked state. When the inner tube 200 is in the locked state, the locking member 410 can pass through the through groove 120 and engage with one of the locking holes 210, thereby fixing the relative position of the inner tube 200 and the outer tube 100. When the inner tube 200 is in the unlocked state, the locking member 410 can disengage from the locking hole 210 and the through groove 120, allowing the inner tube 200 to slide along the inner cavity 470. One end of the connecting member 420 is connected to the locking member 410, and the other end is connected to the driving member 320. The inner tube 200 has a supported state and a non-supported state, as shown in the figure. Figure 5 and Figure 6 As shown, when the inner tube 200 is in a non-supported state, that is, when the inner tube 200 is not in contact with the vehicle floor or the contact with the vehicle floor is insufficient, the support mechanism 1000 is not installed in place, the marking element 310 is in the initial state and displays the first marking 311. (Refer to...) Figure 8 and Figure 9 As shown, when the inner tube 200 is in a supported state, the bottom end of the inner tube 200 abuts against the vehicle floor, and the support mechanism 1000 is installed in place, the vehicle floor can apply upward pressure to the inner tube 200, thereby driving the inner tube 200 to move upward. At the same time, since the length of the through groove 120 in the vertical direction is greater than the length of the locking hole 210 in the vertical direction, the inner tube 200 can drive the locking member 410 to move upward along the through groove 120 through the locking hole 210. The locking member 410 is connected to the connecting member 420. Therefore, the locking member 410 can drive the connecting member 420 to move upward. The connecting member 420 is connected to the driving member 320. The connecting member 420 can drive the driving member 320 to move upward. The upward movement of the driving member 320 can drive the marking member 310 to rotate, so that the marking member 310 can display the second marking 312. In this embodiment, the lower end face of the inner tube 200 may be provided with anti-slip teeth. It is understood that the lower end face of the inner tube 200 is the end that abuts against the vehicle floor. The anti-slip teeth can reduce the possibility of the inner tube 200 becoming loose and improve the stability of the support mechanism 1000.

[0050] Reference Figure 2 and Figure 4As shown, in this embodiment of the invention, the top end of the inner tube 200 may be provided with a limiting part 220, which may be sleeved on the top end of the inner tube 200. The support mechanism 1000 may further include a stop member 500, which may include a stop part 510. The stop part 510 passes through the bottom opening of the outer tube 100 and is fixedly connected to the outer tube 100. The width of the limiting part 220 may be greater than that of the inner tube 200, and the width of the stop part 510 may match that of the limiting part 220, so that the stop part 510 can abut against the limiting part 220 to stop the inner tube 200. Specifically, when the top end of the inner tube 200 slides close to the bottom opening of the outer tube 100, in order to prevent the inner tube 200 from detaching from the outer tube 100, the stop part 510 may abut against the limiting part 220, thereby preventing the inner tube 200 from continuing to slide downward.

[0051] In this embodiment of the invention, the height of the support mechanism 1000 is adjusted by sliding the outer tube 100 and the inner tube 200. The stop member 500 and the limiting part 220 prevent the inner tube 200 from detaching from the outer tube 100. The height of the support mechanism 1000 is fixed by engaging the locking member 410 with one of the locking holes 210. Furthermore, by providing a display component 300, when the inner tube 200 is in a non-supported state, the indicator 310 displays a first indicator 311. When the bottom end of the inner tube 200 abuts against the vehicle floor, the inner tube 200 is in a supported state. This allows the inner tube 200 to drive the locking member 410 upward along the through groove 120 via the locking hole 210, simultaneously driving the connecting member 420 upward. The upward movement of the connecting member 420 can... The drive component 320 moves upward, causing the indicator component 310 to rotate, thereby displaying the second indicator 312 on the indicator component 310. By displaying either the first indicator 311 or the second indicator 312 on the indicator component 310, the user can clearly know whether the support mechanism 1000 is in a supported state. This allows the user to clearly see whether the support mechanism 1000 is in full contact with the floor, thus confirming whether the support legs are installed correctly. This not only reduces the time required for the user to install the support mechanism 1000, but also improves the installation efficiency and reduces the installation difficulty. Furthermore, it improves the installation accuracy, stability, and reliability of the support mechanism 1000, greatly enhancing the user experience.

[0052] Reference Figure 2 , Figure 4 and Figure 7As shown, in this embodiment of the invention, the outer tube 100 may be provided with two sliding grooves 130 extending in the vertical direction. The two sliding grooves 130 are arranged opposite to each other, that is, the two sliding grooves 130 may be located on both sides of the side wall of the outer tube 100 facing the locking assembly 400. The locking assembly 400 also includes a pressing member 430 slidably connected to the two sliding grooves 130. It should be noted that the upper end of the two sliding grooves 130 is provided with an opening. Therefore, the pressing member 430 can enter the sliding groove 130 from the upper opening and slide along the sliding groove 130, thereby reducing the installation difficulty of the pressing member 430 and improving the installation efficiency of the pressing member 430. The pressing member 430 is provided with two rotating parts 431 that correspond one-to-one with the two sliding grooves 130. The two rotating parts 431 are respectively located at both ends of the pressing member 430. The rotating parts 431 can extend into the corresponding sliding grooves 130 and be rotatably connected to the corresponding sliding grooves 130. At the same time, the rotating parts 431 can also be slidably connected to the sliding grooves 130, thereby driving the pressing member 430 to slide along the two sliding grooves 130.

[0053] Reference Figure 4 , Figure 6 and Figure 7 As shown, in this embodiment of the invention, the pressing member 430 and the locking member 410 can be fixedly connected. Specifically, the pressing member 430 may include a snap-fit ​​part 411 and a fixing part 412 connected to each other. The snap-fit ​​part 411 can pass through the through groove 120 and engage with the locking hole 210. The fixing part 412 can pass through the pressing member 430 and be fixedly connected to the pressing member 430. Specifically, the two can be connected by snap-fit, screw, or interference fit. This embodiment does not limit this. The pressing member 430 can drive the locking member 410 to rotate toward or away from the locking hole 210. Specifically, the pressing member 430 may be provided with a pressing part 432 for the user to press. When the user presses the pressing part 432, the pressing part 432 can drive the locking part 410 to rotate around the rotating part 431 away from the card hole 210, thereby causing the locking part 410 to leave the card hole 210 and the through groove 120, and the inner tube 200 to switch to the active state.

[0054] Reference Figure 2 , Figure 4 and Figure 5As shown, in this embodiment of the invention, the connector 420 can be inserted into any of the slide grooves 130. Specifically, the connector 420 can enter the slide groove 130 from the upper opening of the slide groove 130. The pressing member 430 and the connector 420 can enter the slide groove 130 sequentially, thereby completing the installation. This greatly reduces the installation difficulty of the pressing member 430 and the connector 420 and improves the installation efficiency. The driving member 320 may include a connecting part 321. The connecting part 321 can be disposed at the lower part of the driving member 320. The connecting part 321 can enter the slide groove 130 from the upper opening of the slide groove 130, so that the connecting part 321 and the connector 420 are located in the same slide groove 130. One end of the connector 420 abuts against the corresponding rotating part 431, and the other end abuts against the connecting part 321. It can be understood that the two rotating parts 431 of the pressing part 430 are respectively located in two slide grooves 130, and the connector 420 can be set in one of the slide grooves 130. Therefore, the lower end of the connector 420 can abut against the connecting part 321 located in the slide groove 130, and the upper end of the connector 420 can abut against the connecting part 321.

[0055] Understandably, since the connector 420 abuts against the rotating part 431 and the connecting part 321 respectively, when the inner tube 200 abuts against the vehicle floor, the vehicle floor can apply upward pressure to the inner tube 200, thereby driving the inner tube 200 to move upward. The inner tube 200 can drive the locking part 410 to move upward along the through groove 120 through the locking hole 210. The locking part 410 drives the pressing part 430 to move upward. The pressing part 430 drives the connector 420 to move upward through the connecting part 321. The connector 420 drives the driving part 320 to move upward through the connecting part 321. The upward movement of the driving part 320 can drive the marking part 310 to rotate, so that the marking part 310 can display the second marking 312.

[0056] Reference Figure 2 , Figure 3 and Figure 5As shown, in this embodiment of the invention, the display component 300 may further include a base 330 connected to the outer tube 100. Specifically, the base 330 may be snapped onto the outer peripheral wall of the outer tube 100 or connected by screws; this embodiment does not limit this. The base 330 is also provided with a mounting groove 331 suitable for inserting the drive member 320. The mounting groove 331 may be located on the base 330 near the slide groove 130, and the mounting groove 331 extends downward to form a space suitable for accommodating the drive member 320 and for allowing the drive member 320 to move. The drive member 320 may be installed in the mounting groove 331 and may move up and down along the mounting groove 331. The marker 310 is rotatably connected to the base 330, and the bottom end of the marker 310 abuts against the top end of the drive member 320. The connecting part 321 passes through the slide groove 130, and the top end of the driving member 320 abuts against the marking member 310 to fix the driving member 320. The connection between the slide groove 130 and the connecting part 321 can also guide the movement of the driving member 320.

[0057] Reference Figure 3 , Figure 5 and Figure 8 As shown, in this embodiment of the invention, the base 330 may also be provided with two oppositely arranged slots 332, and the identifier 310 is provided with two hinge portions 313 corresponding to the two slots 332 respectively. The two hinge portions 313 are respectively provided at both ends of the identifier 310, and the hinge portions 313 can pass through the corresponding slots 332, thereby realizing the rotatable connection between the identifier 310 and the base 330. The display assembly 300 may also include a tension spring 340, a first shaft is provided between the two slots 332, and the identifier 310 may be provided with a second shaft 314. One end of the tension spring 340 is connected to the first shaft 333, and the other end is connected to the second shaft 314. Understandably, when the inner tube 200 is in a non-supported state, the marker 310 is in its initial state, and the tension spring 340 is in a relaxed state. When the inner tube 200 is in a supported state, the drive member 320 moves upward and drives the marker 310 to rotate. After the marker 310 rotates, the tension spring 340 is in a tense state. When the inner tube 200 returns to a non-supported state, the tension spring 340 can push the marker 310 to rotate and reset.

[0058] Reference Figure 2 , Figure 5 and Figure 8As shown, in this embodiment of the invention, the display component 300 may further include a cover 350, which can cover the base 330. Specifically, the cover 350 and the base 330 may be detachably connected. When the cover 350 is connected to the base 330, it can form a space capable of accommodating the identifier 310, the tension spring 340, and the drive member 320. Therefore, the identifier 310 is located between the base 330 and the cover 350. A viewing window 351 is provided at the position corresponding to the identifier 310 on the cover 350, allowing the user to view the identifier 310 through the viewing window 351. When the inner tube 200 is in a non-supported state, the viewing window 351 corresponds to the first identifier 311, allowing the user to view the first identifier 311 and thus know that the current support structure is not installed correctly. When the inner tube 200 is in a supported state, the viewing window 351 corresponds to the second identifier 312, allowing the user to view the second identifier 312 through the viewing window 351 and thus know that the current support structure is installed correctly.

[0059] Reference Figure 4 , Figure 7 and Figure 9 As shown, in this embodiment of the invention, the locking assembly 400 may further include a cover plate 440, a reset member 450, and an elastic member 460. The cover plate 440 may be fixedly connected to the outer tube 100. Specifically, the cover plate 440 may be snap-fitted to the outer tube 100 or screwed together; this embodiment does not limit this. The cover plate 440 and the peripheral wall of the outer tube 100 may form an inner cavity 470. The cover plate 440 has a through hole 441 communicating with the inner cavity 470. The reset member 450, the elastic member 460, the pressing member 430, and the locking member 410 are all disposed within the inner cavity 470. The pressing member 430 passes through the through hole 441 and is exposed outside the cover plate 440. The through hole 441 may extend vertically, therefore, the pressing member 430 may move vertically along the through hole 441. One end of the elastic member 460 abuts against the top wall of the cover plate 440, and the other end abuts against the reset member 450. (Refer to...) Figure 6 and Figure 7 As shown, the reset member 450 has an inclined surface 451 at one end facing the pressing member 430, which abuts against the pressing member 430. When the pressing member 430 rotates, it can drive the reset member 450 to move upward and squeeze the elastic member 460. Specifically, when the pressing part 432 receives pressure, it can drive the locking member 410 to rotate around the rotating part 431 away from the card hole 210 and the through groove 120. The pressing part 432 then rotates towards the outer tube 100, thereby squeezing the inclined surface 451, which in turn causes the reset member 450 to move upward and squeeze the elastic member 460. When the pressing force received by the pressing part 432 disappears, the elastic member 460 can push the reset member 450 downward, and the pressing part 432 can move along the inclined surface 451 and rotate away from the outer tube 100, thus realizing the reset of the pressing member 430.

[0060] Reference Figure 2 and Figure 4As shown, in this embodiment of the invention, the outer tube 100 is provided with two insertion holes 140, which are respectively located at both ends of the outer tube 100. The stop member 500 includes two snap-fit ​​parts 520 that correspond one-to-one with the two insertion holes 140. The two snap-fit ​​parts 520 can be located at both ends of the stop member 500. The snap-fit ​​parts 520 pass through the corresponding insertion holes 140 to snap-fit ​​with the outer tube 100, thereby realizing the fixed connection between the stop member 500 and the outer tube 100 and reducing the possibility of the inner tube 200 detaching from the outer tube 100.
