Description

Technical Field

[0001] This invention relates to the field of children's products technology, specifically to a base and a child safety seat. Background Technology

[0002] Child safety seats are primarily used when children are riding in cars to improve their safety. A child safety seat generally consists of a base and the seat itself, which is mounted on the base. Due to differences in car design, the angle at which car seats are tilted relative to the horizontal varies, resulting in different backrest angles when a child safety seat is installed in different car seats. To ensure children can sit comfortably at the initially designed angle, some child safety seats incorporate an angle adjustment mechanism on the base. However, after installation, it's not immediately obvious whether the base is properly installed; it needs to be checked to ensure correct placement. Otherwise, an improperly installed base may prevent the child safety seat from effectively protecting the child. Summary of the Invention

[0003] The purpose of this invention is to address the shortcomings of existing technologies by providing a base that allows for a more intuitive way of determining whether the device is properly installed.

[0004] To achieve the above objectives, the technical solution adopted by the present invention is as follows: A base, comprising: Base body; A support assembly is movably disposed below the rear of the base body to adjust the installation angle of the base body. The support assembly includes a first support seat movably connected to the base body and a second support seat movably connected to the first support seat. The second support seat extends downward to the lower part of the first support seat. The display device includes a display element movably disposed on the base body, the display element having first display information and second display information; A connector is attached between the display and the second support base to cause the display to move and display different information when the second support base moves relative to the first support base.

[0005] In some embodiments, the support component has multiple positions relative to the base body, and when the support component moves relative to the base body to adjust the position, the display component is fixed relative to the base body.

[0006] In some embodiments, the connector includes a flexible sleeve and a connecting rope partially passing through the sleeve. The connecting rope is movable along the sleeve. The two ends of the sleeve are respectively fixedly disposed on the base body and the first support seat. The two ends of the connecting rope are respectively fixedly connected to the display element and the second support seat. When the support component moves relative to the base body to adjust its position, the sleeve bends, and the position of the connecting rope relative to the sleeve remains unchanged. When the second support moves relative to the first support, the sleeve is fixed, and the position of the connecting rope relative to the sleeve changes.

[0007] In some embodiments, the two ends of the sleeve along its length are a first end and a second end, the first end being fixedly disposed on the base body and the second end being fixedly disposed on the first support base; The two ends of the connecting rope along its length are the third end and the fourth end, respectively. The third end is connected to the display component, and the fourth end is connected to the second support base. The connecting rope extends along its length and includes a first segment, a second segment, and a third segment arranged in sequence. The first segment and the third segment are both located outside the sleeve, the second segment is housed inside the sleeve, the first segment is located between the first end and the third end, and the third segment is located between the second end and the fourth end. When the support component moves relative to the base body to adjust its position, the lengths of the first segment, the second segment, and the third segment remain unchanged. When the second support moves relative to the first support, the length of the second segment remains unchanged, the length of one of the first segment and the third segment increases, and the length of the other segment decreases, with the increase and decrease being the same.

[0008] In some embodiments, the connector is a traction cable.

[0009] In some embodiments, the second support base has a first position and a second position relative to the first support base; When the second support is in the first position, the display shows first information; when the second support is in the second position, the display shows second information. The second support moves upward relative to the first support, causing the second support to move from the first position to the second position.

[0010] In some embodiments, the support assembly further includes a first elastic member disposed between the first support base and the second support base, the first elastic member applying a downward elastic force to the second support base to cause the second support base to tend to move toward a first position.

[0011] In some embodiments, the support assembly further includes a second elastic member disposed between the base body and the first support seat, the second elastic member applying a downward elastic force to the first support seat to cause the support assembly to have a downward movement tendency, and the elastic force of the second elastic member is less than the elastic force of the first elastic member.

[0012] In some embodiments, the display device further includes a third elastic member disposed between the base body and the display element, the third elastic member applying an elastic force to the display element to cause the display element to have a tendency to move in the direction of displaying second display information when the second support is in the second position.

[0013] In some embodiments, the display element is rotatably mounted on the base body, and the first display information and the second display information are sequentially arranged along the rotation direction of the display element.

[0014] In some embodiments, the support assembly moves relative to the base body in multiple positions. The base also includes a locking structure disposed between the base body and the first support to lock their relative positions. The locking structure includes a locking member movably disposed on one of the base body and the first support and a locking groove fixedly disposed on the other. Multiple locking grooves are sequentially spaced along the direction of movement of the first support relative to the base body. When the locking structure is in the locked state, the locking element is engaged in one of the lock slots; when the locking structure is in the unlocked state, the locking element is disengaged from all of the lock slots.

[0015] In some embodiments, the components of the base body and the first support seat that are provided with locking slots are further provided with sliding grooves extending along the movement direction of the first support seat, and the sliding grooves are respectively connected to each of the locking slots; when the locking structure is in the unlocked state, the locking member is located in the sliding groove and can move along the extension direction of the sliding groove.

[0016] In some embodiments, the locking structure further includes a locking bar rotatably disposed on the base body, a locking member fixedly disposed at one end of the locking bar, and the base further includes an unlocking mechanism for driving the locking structure to unlock from the locked state, the unlocking mechanism including an unlocking member movably disposed on the base body, the unlocking member being movably connected to the other end of the locking bar; The unlocking component is slidably disposed on the base body, and the unlocking component is rotatably and slidably connected to the other end of the locking rod; Alternatively, the base may further include an unlocking mechanism for driving the locking structure to unlock from the locked state, the unlocking mechanism including an unlocking element movably disposed on the base body, the unlocking element cooperating with the locking element.

[0017] In some embodiments, the first support base is slidably mounted on the base body; And / or, the second support can be slidably mounted on the first support; And / or, a guide block is provided inside the base body, the first support seat is sleeved on the outside of the guide block, and the second support seat is sleeved on the outside of the first support seat.

[0018] The present invention also provides a child safety seat having a base as described in any of the preceding claims.

[0019] Due to the application of the above technical solution, the present invention has the following advantages compared with the prior art: In the base of the present invention, the position of the support component on the base body can be adjusted by moving the first support seat relative to the base body, thereby adjusting the installation angle of the base body to improve the comfort of children riding in child safety seats. Moreover, when the base is not installed on the car seat, the display shows one type of information. When the base is installed on the car seat, the second support seat slides relative to the first support seat, causing the display to move relative to the base body. Thus, when the base body is properly installed on the car seat, the display shows different information. This allows for intuitive judgment of whether the base is properly installed based on the information displayed, eliminating the need for inspection and making the child safety seat convenient to use. It also ensures that the base is correctly installed on the car seat, enabling the child safety seat to effectively protect the child. Attached Figure Description

[0022] The technical solution of the present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0023] In the following description, the directions "front," "back," "left," "right," "up," and "down" all refer to... Figure 4 In the figure, the right direction is "rear", the left direction is "front", the upper direction is "up", and the lower direction is "down". The directions perpendicular to the paper are "left" and "right". The above definitions of directions are only for the convenience of describing the present 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 limiting the present invention.

[0024] Example 1 The child safety seat in this embodiment includes a base and a seat body (not shown in the figure) mounted on the base.

[0025] like Figures 1-24 As shown, the base includes a base body 1, a support component 2, a display device 3, and a connector.

[0026] The seat body is mounted on the base body 1.

[0027] The support component 2 is movably positioned at the lower rear of the base body 1. By adjusting the position of the support component 2 on the base body 1, the installation angle of the base body 1 can be adjusted to accommodate the backrest angles of different car seats, thereby stably installing the child safety seat on the car seat and improving the comfort and safety performance of the child safety seat during use.

[0028] like Figure 4 , Figure 5 , Figure 8 , Figure 12 , Figure 16 , Figure 17 , Figure 20 and Figure 24 As shown, the support assembly 2 includes a first support base 21 and a second support base 22. The first support base 21 is movably mounted on the base body 1, and the second support base 22 is movably mounted on the first support base 21. The second support base 22 extends downward to the lower part of the first support base 21.

[0029] The support assembly 2 has multiple positions relative to the base body 1. By moving the first support seat 21 relative to the base body 21, the support assembly 2 is positioned in different positions. During this process, the second support seat 22 is fixed relative to the first support seat 21. When the base is installed on a car seat, the bottom of the second support seat 22 abuts against the car seat, causing the second support seat 22 to move upward relative to the first support seat 21. During this process, the first support seat 21 is fixed relative to the base body 1.

[0030] like Figure 5 and Figure 17 As shown, the support assembly 2 also includes a first elastic element 23, which is disposed between the first support base 21 and the second support base 22. The first elastic element 23 applies a downward elastic force to the second support base 22, causing the second support base 22 to have a downward tendency to move.

[0031] The second support 22 has a first position and a second position relative to the first support 21. When the bottom of the second support 22 is not subjected to external force, the elastic force of the first elastic element 23 keeps the second support 22 in the first position, such as... Figure 4 , Figure 5 , Figure 8 , Figure 16 , Figure 17 and Figure 20 As shown. When the base is installed on the car seat, the bottom of the second support 22 is subjected to an external force, namely the abutment of the car seat 8, which causes the second support 22 to be in the second position, as shown. Figure 12 and Figure 24 As shown.

[0032] like Figure 5 and Figure 17 As shown, the support assembly 2 also includes a second elastic element 24, which is disposed between the base body 1 and the first support seat 21. The second elastic element 24 applies a downward elastic force to the first support seat 21, causing the support assembly 2 to have a downward tendency to move. That is, the entire support assembly 2 moves downward under the action of the elastic force of the second elastic element 24 to adjust the gear position.

[0033] The elastic force of the second elastic element 24 is less than that of the first elastic element 23. When the support assembly 2 moves upward to adjust the gear position, force is applied to the bottom of the second support seat 22. Since the elastic force of the second elastic element 24 is less than that of the first elastic element 23, the second elastic element 24 undergoes elastic deformation, while the first elastic element 23 does not undergo elastic deformation. This prevents the second support seat 22 from moving relative to the first support seat 21, and the support assembly 2 moves upward as a whole.

[0034] In this embodiment, the first support base 21 is slidably mounted on the base body 1, and the second support base 22 is slidably mounted on the first support base 21.

[0035] In this embodiment, a guide block 12 is fixedly mounted on the base body 1, a first support seat 21 is slidably sleeved on the outside of the guide block 12, and a second elastic element 24 is disposed between the guide block 12 and the first support seat 21. A second support seat 22 is slidably sleeved on the outside of the first support seat 21. When the support assembly 2 is adjusted to a different position, the sliding of the first support seat 21 is guided by the cooperation between the first guide block 12 and the first support seat 21. The sliding of the second support seat 22 is guided by the cooperation between the first support seat 21 and the second support seat 22.

[0036] like Figure 4 , Figure 8 , Figure 12 , Figure 16 , Figure 20 and Figure 24 As shown, the display device 3 includes a display element 31 movably disposed on the base body 1, and the display element 31 has first display information 311 and second display information 312.

[0037] like Figure 1 , Figure 6 , Figure 10 , Figure 13 , Figure 18 and Figure 22 As shown, a display window 11 is provided on the base body 1. The display component 31 can be moved relative to the base body 1 so that one of the first display information 311 and the second display information 312 is aligned with the display window.

[0038] In this embodiment, the display element 31 is rotatably mounted on the base body 1, and the first display information 311 and the second display information 312 are arranged sequentially along the rotation direction of the display element 31.

[0039] The connector 4 is connected between the display element 31 and the second support base 22, so that when the second support base 22 moves relative to the first support base 21, the display element 31 moves relative to the base body 1, thereby aligning one of the first display information 311 and the second display information 312 with the display window, and the display element 31 displays different display information.

[0040] Specifically, when the second support 22 is in the first position, the first display information 311 of the display component 31 is aligned with the display window 11, such as... Figure 4 , Figure 8 , Figure 16 , Figure 17 and Figure 20 As shown. When the second support 22 is in the second position, the second display information 312 of the display element 31 is aligned with the display window 11, as shown. Figure 12 and Figure 24 As shown.

[0041] like Figure 4 , Figure 8 , Figure 12 , Figure 16 , Figure 20 and Figure 24 As shown, the connector 4 includes a flexible sleeve 41 and a connecting rope 42 partially passing through the sleeve 41. The connecting rope 42 can move along the sleeve 41. The two ends of the sleeve 41 are respectively fixedly mounted on the base body 1 and the first support 21. The two ends of the connecting rope 42 are respectively fixedly connected to the display component 31 and the second support 22, and are tensioned between the display component 31 and the second support 22.

[0042] When the first support 21 moves to adjust its position relative to the base body 1, the second support 2 is always in the first position. The connecting rope 42 bends with the sleeve 42, but the position of the connecting rope 42 relative to the sleeve 41 remains unchanged, thereby fixing the display 31 relative to the base body 1. In this way, the first display information 311 of the display 31 is always aligned with the display window 11.

[0043] When the second support 22 moves relative to the first support 21, the sleeve 41 is fixed. The second support 22 pulls the connecting rope 42 to move relative to the sleeve 41. The position of the connecting rope 42 relative to the sleeve 41 changes, and the connecting rope 42 can move the display component 31 relative to the base body 1 in conjunction with it.

[0044] Specifically, the two ends of the sleeve 41 along its length are a first end 411 and a second end 412, respectively. The first end 411 is fixedly mounted on the base body 1, and the second end 412 is fixedly mounted on the first support 21.

[0045] The two ends of the connecting rope 42 along its length are the third end 421 and the fourth end 422, respectively. The third end 421 is connected to the display component 31, and the fourth end 422 is connected to the second support base 22.

[0046] The connecting rope 42 includes a first segment 423, a second segment 424, and a third segment 425 arranged sequentially along its length. The first segment 423 and the third segment 425 are both located outside the sleeve 41, while the second segment 424 is housed within the sleeve 41. The first segment 423 is located between the first end 411 and the third end 421, and the third segment 425 is located between the second end 412 and the fourth end 422.

[0047] When the first support 21 moves relative to the base body 1 to adjust its position, the second support 22 remains in the first position, and the lengths of the first segment 423, the second segment 424, and the third segment 425 remain unchanged. Figure 4 and Figure 16 As shown. In this way, the display element 31 does not move relative to the base body 1, and the first display information 311 of the display element 31 is always aligned with the display window 11.

[0048] When the second support 22 moves from the first position to the second position relative to the first support 21, the length of the third segment 425 decreases, the length of the second segment 424 remains unchanged, the length of the first segment 423 increases, and the decrease in the length of the third segment 425 is the same as the increase in the length of the first segment 423.

[0049] The display device also includes a third elastic member (not shown in the figure) disposed between the base body 1 and the display element 31. The third elastic member applies an elastic force to the display element 31, causing the display element 31 to tend to move in the direction of displaying the second display information 312.

[0050] When the length of the first segment 423 increases, the display element 32 moves relative to the base body 1 under the elastic force of the third elastic element, thereby aligning the second display information 312 of the display element 31 with the display window 11.

[0051] When the second support 22 moves from the second position to the first position relative to the first support 21, the length of the third segment 425 increases, the length of the second segment 424 remains unchanged, and the length of the first segment 423 decreases, with the increase in the length of the third segment 425 being the same as the decrease in the length of the first segment 423. When the length of the first segment 423 is small, the connecting rope 42 pulls the display element 32 to overcome the elastic force of the third elastic element and move in the opposite direction relative to the base body 1, thereby aligning the first display information 311 of the display element 31 with the display window 11.

[0052] In this embodiment, the connector 4 can be a traction cable.

[0053] The base also includes a locking structure, which is disposed between the base body 1 and the first support seat 21 to lock their relative positions, thereby locking the support component 2 in different gear positions. When the locking structure is in the locked state, the first support seat 21 is fixed relative to the base body 1, thus preventing the support component 2 from adjusting its gear position relative to the base body 1. When the locking structure is in the unlocked state, the support component 2 as a whole can move relative to the base body 1 to adjust its gear position.

[0054] The locking structure includes a locking member 51 movably disposed on one of the base body 1 and the first support 21 and a locking groove 211 fixedly disposed on the other. Multiple locking grooves 211 are arranged sequentially at intervals along the movement direction of the first support 21 relative to the base body 1.

[0055] When the locking structure is in the locked state, the locking element 51 is engaged in a locking groove 211, such as Figure 8 and Figure 20 As shown. When the locking member 51 is in different lock slots 211, the support assembly 2 is in different positions. When the locking structure is in the unlocked state, the locking member 51 disengages from all lock slots 211, as shown. Figure 4 and Figure 16 As shown.

[0056] The base body 1 and the first support seat 21 are provided with a sliding groove 212 on the component with the locking groove 211. The sliding groove 212 extends along the movement direction of the first support seat 21 and is connected to each locking groove 211.

[0057] When the locking structure is in the unlocked state, the locking element 51 enters the slide groove 212 from the locking groove 211, such as... Figure 4 and Figure 16 As shown. When the first support 21 moves to the adjustment position relative to the base body 1, the locking member 51 moves along the extension direction of the slide groove 212, thereby guiding and limiting the movement of the first support 21.

[0058] In this embodiment, such as Figure 4 , Figure 8 , Figure 12 , Figure 16 , Figure 20 and Figure 24 As shown, the locking structure also includes a locking rod 5 that is rotatably mounted on the base body 1, and the aforementioned locking member 51 is fixedly mounted on one end of the locking rod 5.

[0059] The base also includes an unlocking mechanism. When the locking structure is in the locked state, the unlocking mechanism can be operated to unlock the locking structure from the locked state.

[0060] The unlocking mechanism includes an unlocking component 6, which is movably mounted on the base body 1 and is movably connected to the end of the locking rod 5 away from the locking component 51.

[0061] In this embodiment, such as Figure 4 , Figure 8 , Figure 12 , Figure 16 , Figure 20 and Figure 24 As shown, the unlocking component 6 is slidably mounted on the base body 1, and the unlocking component 6 is rotatably and slidably connected to the locking rod 5. Specifically, the lower end of the unlocking component 6 is provided with a first guide groove 61, and the rotating shaft 7, which is rotatably connected to the unlocking component 6 and the locking rod 5, is slidably mounted in the first guide groove 61. The first guide groove 61 is inclined relative to the sliding direction of the unlocking component 6.

[0062] When the locking structure is in the locked state, the rotating shaft 7 is located at the upper end of the first guide groove 61.

[0063] When the unlocking piece 6 is pulled and slids upward relative to the base body 1, the first guide groove 61 moves upward relative to the rotating shaft 7. At the same time, the first guide groove 61 acts on the rotating shaft 7, causing the locking rod 5 to rotate relative to the base body 1, so that the locking piece 51 disengages from the locking groove 211 and enters the sliding groove 212. The locking structure is then in the unlocked state, and the support assembly 2 can slide upward or downward relative to the base body 1 to adjust the gear position.

[0064] Alternatively, the first guide groove 61 can be set on the locking rod 5, so that when the locking structure is in the locked state, the rotating shaft 7 is located at the lower end of the first guide groove 61.

[0065] The base also includes a fourth elastic element 52, which is disposed between the base body 1 and the locking rod 5. The fourth elastic element 52 applies an elastic force to the locking rod 5, causing the locking rod 5 to tend to move in the direction that causes the locking member 51 to enter the locking groove 211. That is, when the locking structure is in the unlocked state, after the first support seat 21 moves relative to the base body 1 to the position corresponding to the locking member 51 in the locking groove 211, the unlocking member 6 is released, and the locking rod 5 rotates in the opposite direction relative to the base body 1 under the action of the fourth elastic element 52, causing the locking member 51 to enter the locking groove 211 from the sliding groove 212, and the locking structure is in the locked state.

[0066] Alternatively, when the locking structure is in the unlocked state, the unlocking member 6 can be moved in the reverse direction to put the locking structure back into the locked state. Specifically, when the first support base 21 moves relative to the base body 1 to the position where the locking groove 211 corresponds to the locking member 51, the unlocking member 6 slides downward relative to the base body 1, which allows the first guide groove 61 to move downward relative to the rotating shaft 7. At the same time, the first guide groove 61 acts on the rotating shaft 7, causing the locking rod 5 to rotate in the reverse direction relative to the base body 1, so that the locking member 51 enters the locking groove 211 from the sliding groove 212, and the locking structure is in the locked state.

[0067] Example 2 In this embodiment, the locking structure and unlocking mechanism are different from those in Embodiment 1, but the rest are the same as in Embodiment 1.

[0068] The locking element 51 is movably mounted on the base body 1, and the unlocking element 6 is movably mounted on the base body 1. The unlocking element 6 cooperates with the locking element 51, so that when the unlocking element 6 moves relative to the base body 1, the locking element 51 moves relative to the base body 1 through the cooperation of the unlocking element 6 and the locking element 51, thereby switching the locking structure between the locked state and the unlocked state.

[0069] Specifically, such as Figures 25-27 As shown, the guide block 12 is provided with an elongated guide hole 121 extending in the front-back direction, and the locking member 51 is movably disposed in the elongated guide hole 121.

[0070] The unlocking member 6 is provided with a second guide groove 62 at one end near the locking member 51. The second guide groove 62 has a portion that extends obliquely in the vertical direction, and the locking member 51 is movably disposed in the second guide groove 62.

[0071] When the locking structure moves the unlocking member 6 upward in the locked state, the locking member 51 will slide from one end of the elongated guide hole 121 to the other end under the push of the inclined groove wall of the second guide slide 62, that is, it will disengage from the lock groove 211 and enter the slide 212, thus unlocking the locking structure and making the support component 2 adjustable in position.

[0072] Conversely, when the locking structure moves the unlocking member 6 downward in the unlocked state, the second guide groove 62 pushes the locking member 51 to move in the opposite direction along the elongated guide hole 121 through the inclined groove wall, so that the locking member 51 is disengaged from the slide groove 212 and enters the lock groove 211, and the locking structure is locked.

[0073] The second guide groove 62 is formed by connecting the first guide section and the second guide section. The first guide section extends along the sliding direction of the unlocking member 6, i.e., the vertical direction. The second guide section is inclined relative to the sliding direction of the unlocking member 6, and the first and second guide sections are set at an angle. When the locking member 51 is engaged in the lock groove 211, the locking member 51 is located in the first guide section. At this time, when the unlocking member 6 is accidentally touched by an external force, the locking member 51 will move within the first guide section first. Since the extension direction of the first guide section is consistent with the sliding direction of the unlocking member 6, the inner wall of the first guide section will not exert a pushing force on the locking member 51, so that the locking member 51 remains in its current position. When the user applies force to the unlocking member 6, the locking member 51 will first slide out of the first guide section and then enter the second guide section. Then, under the restraint of the inclined inner wall of the second guide section and the elongated guide hole 121, it will disengage from the lock groove 211. This setting can effectively prevent the unlocking member 6 from accidentally disengaging the locking member 51 from the lock groove 211.
