[0077] The present invention will be described in detail below with reference to the accompanying drawings.

[0078] exist Figure 1 In the illustrated embodiment, a support leg device 10 is provided at the front end of the base of the safety seat, and when in use, the lower end of the support leg device can be supported on the ground inside the car. The support leg device 10 includes a first pipe member 20 and a second pipe member 30, and the second pipe member 30 is slidably disposed in the first pipe member 20, so that the support leg device 10 can be extended and retracted. Therefore, when the safety seat is placed on the car seat, the length of the support leg device 10 can be adjusted so that the lower end of the support leg device can reach the ground inside the car.

[0079] Next, the structure for displaying whether the foot support device 10 is in contact with the ground will be described in detail.

[0080] The indicator assembly according to the present invention is attached to the support leg device 10. The indicator assembly includes: an indicator housing 110, which is located at the upper end of the support leg device 10, more specifically connected to the upper end of the first tube 20, and has an indicator window 111; an indicator member 100, which is pivotally accommodated in the indicator housing 110; a first elastic member 120, which is disposed in the indicator housing 110 and is used to drive the indicator member 100 to pivot along a first direction; a push member 200 and a driving member 300, both of which are located inside the support leg device 10 and extend in the longitudinal direction of the support leg device.

[0081] like Figure 1 As shown, the indicator housing 110 can be formed as a connecting part connecting the support leg device 10 and the base of the safety seat. Therefore, the indicator housing 110 can be formed as a whole with the support leg device 10 and the base of the safety seat, so that the three have sufficient strength to ensure that the support leg device 10 plays a supporting role for the safety seat. Of course, in order to facilitate manufacturing and transportation, the three can also be made into separate components and then assembled together by screwing, riveting or welding.

[0082] The indicating housing 110 is provided with an indicating window 111 which penetrates the indicating housing 110 . Figure 1 and Figure 2 In the illustrated embodiment, the indication window 111 is formed at the top of the indication housing 110 so that the user can more conveniently observe the indication window 111 from above. However, it should be understood that the indication window 111 may also be formed at the side of the indication housing 110 so that the user can observe the indication window 111 from the side.

[0083] A pivotable indicator 100 is accommodated in the indicator housing 110. The outer surface of the indicator 100 includes a first area 101 and a second area 102, which can be switched to be exposed from the indicator window 111 by pivoting the indicator 100. The first area 101 and the second area 102 can have different colors, such as red and green; or have different patterns, such as text or graphics, so as to display different states of the indicator component. For example, when the support foot device 10 is not touching the ground, the first area 101 of the indicator 100 is exposed from the indicator window 111; when the support foot device 10 is touching the ground, the second area 102 of the indicator 100 is exposed from the indicator window 111. In this way, the user can clearly know the contact situation of the support foot device 10.

[0084] In order to facilitate the pivoting of the indicator 100, a pivot shaft 103 may be formed on both sides of the indicator 100, which is rotatably supported on the indicator housing 110 or supported on the top of the support foot device 10 (i.e., the first tube 20) or supported on the frame 40 (see FIG. 4 ) disposed on the top of the support foot device 10 (i.e., the first tube 20). Figure 4 and Fig.12 ), so that the indicator 100 pivots around the pivot axis 103 in the indicator housing 110. In other embodiments, the indicator 100 can also be pivoted by other means such as a slide rail.

[0085] When the support foot device 10 is not touching the ground, in order to ensure that the first area 101 is exposed from the indication window 111, a first elastic member 120 is further provided in the indication housing 110, which drives the indicator 100 to pivot to the first position along the first direction. When the indicator 100 is in the first position, the first area 101 is exposed from the indication window 111. The first elastic member 120 is made of elastic material and may include a spring, a spring sheet or any elastic element capable of providing a driving force. Moreover, the first elastic member 120 may be integrally formed with the indicator 100, or the two may be formed separately and then assembled together. The first elastic member 120 may be of any shape, for example Figure 6 The spring piece shape is shown, but the present invention is not limited to this.

[0086] When the support leg device 10 touches the ground, the push member 200 and the driving member 300 are mainly used to drive the indicator member 100 to pivot to the second position along the second direction opposite to the first direction. When the indicator member 100 is in the second position, the second area 102 is exposed from the indicator window 111. The push member 200 and the driving member 300 will be described in detail below. Both of them are located inside the support leg device 10. Figure 4 Best shown.

[0087] The push member 200 is located inside the first pipe member 20 and can move up and down relative to the first pipe member 20. In one embodiment, the push member 200 is disposed on the inner side wall of the first pipe member 20. Figure 3 and Fig.11 As shown, a longitudinally extending groove 23 is provided on the inner side wall of the first tube 20, and the push member 200 is a slender member extending in the longitudinal direction of the support foot device 10 (see Figure 5 ), the slender member can be inserted into the groove 23 and move up and down along the groove 23. It should be understood that the push member 200 can also adopt other structures to move up and down along the inside of the first pipe member 20.

[0088] The top end 220 of the pushing member 200 can be connected to the indicator member 100, or can be in contact with the indicator member 100, or can be separated from the indicator member 100 by a small distance, so that when the pushing member 200 moves upward, its top end 220 can push the indicator member 100 and overcome the force of the first elastic member 120 to pivot along the second direction.

[0089] The top 220 can be in any shape, such as round, square, etc., as long as it can push the indicator to pivot.

[0090] The pushing member 200 further has a plurality of engaging holes 210 arranged longitudinally. These engaging holes may be spaced apart at the same interval or at different intervals.

[0091] The upward movement of the push member 200 is mainly achieved by the driving member 300. The driving member 300 is located inside the second pipe member 30 and can move up and down relative to the second pipe member 30.

[0092] The driving member 300 includes an upper end provided with a snap hook 310 and a lower end 320 that can touch the ground. When the lower end 320 of the driving member 300 touches the ground, the driving member 300 moves upward relative to the second pipe member 20. It should be noted that the lower end 320 of the driving member 300 can touch the ground, including two situations where the lower end 320 directly touches the ground and indirectly touches the ground. Among them, the situation where the lower end 320 indirectly touches the ground can be, for example, the lower end 320 is provided with a ground contacting member 321, such as Figure 4 and Figure 5 As shown. The ground contacting member 321 can be made entirely of rubber to avoid damaging the vehicle ground during contact with the vehicle ground. Alternatively, the bottom of the ground contacting member 321 is overmolded with an anti-collision and anti-slip member 322, such as Fig.13 The anti-collision and anti-slip member 322 is made of a thermoplastic elastomer material (ie, TPE material).

[0093] The engaging hook 310 at the upper end of the driving member 300 can be operably engaged with one of the multiple engaging holes 210 of the pushing member 200, wherein the size of the engaging hook 310 is slightly smaller than the size of the engaging hole 210. Preferably, the size of the engaging hook 310 is similar to the size of the engaging hole 210, so that the engaging hook 310 is tightly engaged with the engaging hole 210.

[0094] After the engaging hook 310 is operatively engaged with one of the engaging holes 210, the driving member 300 and the pushing member 200 form a linkage. For example, the upward movement of the driving member 300 will drive the pushing member 200 to move upward. On the other hand, the engaging hook 310 can also be operatively disengaged from the engaging hole 210, so that the driving member 300 and the pushing member 200 no longer form a linkage, thereby avoiding the second pipe member 30 from sliding relative to the first pipe member 20.

[0095] The following combination Figure 5-Figure 7 The matching relationship between the various components in the indicating assembly according to the present invention is described in detail.

[0096] When the lower end 320 of the driving member 300 does not touch the ground, the indicator 100 is pivoted to the first position along the first direction under the action of the first elastic member 120 , so that the first area 101 is exposed from the indicator window 111 .

[0097] When the lower end 320 of the driving member 300 touches the ground, as described above, the driving member 300 moves upward relative to the second tube member 30, and at the same time drives the pushing member 200 to move upward by means of the engagement of the locking hook 310 and the locking hole 210, thereby the top end 220 of the pushing member 200 pushes the indicating member 100 to overcome the force of the first elastic member 120 and pivot to the second position along the second direction, so that the second area 102 is exposed from the indicating window 111.

[0098] In this way, the first area 101 and the second area 101 of the indicator are switched to be exposed from the indicator window 111 under different circumstances, so that the user can more conveniently observe whether the supporting foot device 10 has contacted the ground of the car, ensuring the safety and reliability of the safety seat.

[0099] Next, the locking mechanism of the support foot device 10 will be described in detail.

[0100] That is, the matching structure between the first tube member 20 and the second tube member 30 of the supporting foot device 10 and how the first tube member 20 and the second tube member 30 are locked with each other are described in detail.

[0101] like Fig. 9 As shown, the inner diameter of the first pipe 20 is greater than the outer diameter of the second pipe 30 , so that there is a certain gap between the inner side of the first pipe 20 and the outer side of the second pipe 30 , which is conducive to the relative sliding of the second pipe 30 in the first pipe 20 .

[0102] When the second tube 30 slides relative to the first tube 20 to extend the support leg device 10 to a suitable length, for example, when the support leg device 10 extends to the point where it contacts the ground of the vehicle, the first tube 20 and the second tube 30 need to be locked with each other to keep the support leg device 10 at a suitable length. To this end, a plurality of segment locking holes 21 arranged longitudinally are provided in the first tube 20, and a segment locking member 400 is provided in the second tube 30. Figure 5-Figure 7 In the illustrated embodiment, the segment locking member 400 is provided with a positioning pin 420, which is supported on the inner wall of the second pipe 30, so that the segment locking member 400 can pivot in the second pipe 30. Therefore, after the position of the second pipe 30 relative to the first pipe 20 is determined, the segment locking member 400 can be operatively engaged with one of the plurality of segment locking holes 21, such as Fig.10As shown, the first pipe 20 and the second pipe 30 are mutually locked. The size of the segment locking piece 400 is slightly smaller than the size of the segment locking hole 21. Preferably, the size of the segment locking piece 400 is similar to the size of the segment locking hole 21, so that the segment locking piece 400 is tightly engaged with the segment locking hole 21. In addition, the segment locking piece 400 can have a convex structure, such as a convex piece, a convex rod, etc., but the present invention is not limited thereto. The segment locking piece 400 can be engaged with the segment locking hole 21 in a shape-matched manner.

[0103] During the process of adjusting the length of the supporting leg device 10, the segment locking member 400 can also be operably disengaged from the engaged segment locking hole 21, so that the mutual locking between the first tube 20 and the second tube 30 is unlocked, and the second tube 30 can slide again relative to the first tube 20 to adjust the position of the second tube 30 relative to the first tube 20, which will be described in detail below.

[0104] Next, the unlocking mechanism of the support leg device 10 will be described in detail.

[0105] When the supporting leg device 10 is ready to be folded, the mutual locking between the first tube 20 and the second tube 30 needs to be released, that is, the segment locking member 400 needs to be disengaged from the segment locking hole 21 so that the second tube 30 can slide relative to the first tube 20 .

[0106] The present invention provides a configuration structure for disengaging the segment locking member 400 from the segment locking hole 21 , and the configuration structure can also disengage the engaging hook 310 from the engaging hole 210 at the same time.

[0107] Combination Figure 5-Figure 8 The configuration structure includes a pull rod 500 extending longitudinally in the second pipe 30, and the pull rod can move up and down but cannot move horizontally in the second pipe 30.

[0108] First, in order to make the segment locking member 400 disengage from the segment locking hole 21, the top end of the pull rod 500 is provided with a long oblique groove 510 extending obliquely relative to the longitudinal direction of the support foot device 10, and the segment locking member 400 is provided with a driving pin 410, which passes through the oblique groove 510. The oblique direction of the oblique groove 510 is set so that when the pull rod 500 moves downward, the oblique groove 510 can force the driving pin 410 to move in the horizontal direction, thereby driving the segment locking member 400 to disengage from the segment locking hole 21.

[0109] In one embodiment, the upper portion of the pull rod 500 has an opening, and the segment locking member 400 is located in the opening. Preferably, the opening may be a U-shaped opening. Figure 7As best seen in FIG. 5 , in this case, the inclined grooves 510 are disposed on opposite sides 520 of the U-shaped opening. However, the present invention is not limited thereto, and the opening of the upper portion of the pull rod 500 may also be of other shapes as long as it can accommodate the segment locking member 400. Alternatively, the upper portion of the pull rod 500 may not have an opening, in which case the inclined grooves 510 are formed through the upper portion of the pull rod 500, and the segment locking member 400 is disposed side by side relative to the upper portion of the pull rod 500, so that the driving pin 410 on the segment locking member 400 passes through the inclined grooves 510.

[0110] Secondly, in order to make the engaging hook 310 disengage from the engaging hole 210, the upper part of the driving member 300 is provided with a driving slot 330 extending longitudinally relative to the supporting foot device 10, and the driving pin 410 also passes through the driving slot 330. Therefore, when the driving pin 410 is displaced in the horizontal direction under the action of the inclined slot 510, the driving pin 410 will drive the driving slot 330 and then drive the upper part of the driving member 300 to be displaced in the horizontal direction, so that the engaging hook 310 at the upper end of the driving member 300 is disengaged from the engaging hole 210 of the pushing member 200.

[0111] like Figure 4 and Figure 8 As shown, a support pin 550 can also be fixed to the lower part of the pull rod 500, and the lower part of the driving member 300 has an elongated support groove 340. The support pin 550 passes through the support groove 340, so that the driving member 300 can be supported on the pull rod 500 for upward and downward movement, and the driving member 300 can pivot around the support pin 550, so that the upper part of the driving member 300 can be displaced in the horizontal direction.

[0112] Furthermore, when the support leg device 10 is ready to be folded, the lower end 320 of the driving member 300 no longer touches the ground. In order to ensure that the driving member 300 is reset, a tension spring 350 can be installed between the lower part of the driving member 300 and the lower part of the pull rod 500. The tension spring 350 is arranged to drive the driving member 300 to move downward relative to the pull rod 500. Fig.12 As shown. Fig.12In the embodiment of the present invention, a rivet 360 is provided at the lower part of the driving member 300, and a wing 580 is provided at the lower part of the pull rod 500. One end of the tension spring 350 can be hooked on the rivet 360, and the other end can be hooked on the hole on the wing 580, so as to facilitate the installation of the tension spring 350. Of course, the tension spring 350 can also be installed in other ways. In this way, once the lower end 320 of the driving member 300 no longer touches the ground, the tension spring 350 will pull the driving member 300 to move downward, so the driving member 300 will no longer push the push member 200 upward. At the same time, since the tip of the engaging hook 310 has an inclined lower portion 311, the inclined direction of the inclined lower portion 311 is set so that when the engaging hook 310 moves downward, the inclined lower portion 311 interacts with the lower edge of the engaging hole 210, so that the engaging hook 310 withdraws from the engaging hole 210. In this way, since the driving member 300 no longer generates an upward thrust on the pushing member 200 and the pushing member 200 no longer generates a thrust on the indicating member 100 , the indicating member 100 will pivot to the first position along the first direction under the action of the first elastic member 120 , thereby exposing the first area 101 from the indicating window 111 .

[0113] Again, in order to facilitate the user to move the pull rod 500 downward, in one embodiment of the present invention, a driving inclined surface 530 is provided at the bottom end of the pull rod 500. The driving inclined surface 530 can be integrally formed on both sides of the bottom end of the pull rod 500, or fixed to both sides of the bottom end of the pull rod 500 by means of a connecting piece. At the same time, a stage adjustment button 600 is provided at the bottom end of the supporting foot device 10. Specifically, the stage adjustment button 600 can be set at the bottom end of the second pipe 30. Moreover, a button inclined surface 610 that contacts the driving inclined surface 530 is provided on the stage adjustment button 600. The inclination directions of the driving inclined surface 530 and the button inclined surface 610 are set so that when the stage adjustment button 600 is pressed, the button inclined surface 610 and the driving inclined surface 530 interact with each other, thereby causing the pull rod 500 to move downward. Figure 8 shown.

[0114] In addition, a second elastic member 540 is further provided at the bottom end of the pull rod 500. Figure 8As shown, the second elastic member 540 can be arranged below the bottom end of the pull rod 500 to force the pull rod 500 to move upward, but the position of the second elastic member 540 is not limited to this embodiment. The second elastic member 540 is made of elastic material and can include a spring, a spring or any elastic element that can provide a driving force. Due to the presence of the second elastic member 540, when the segment adjustment button 600 is not pressed, the second elastic member 540 will force the pull rod 500 to move upward, so that the driving inclined surface 530 will push the button inclined surface 610, so that the segment adjustment button 600 is radially outward to the initial position. On the other hand, in order to limit the range of the pull rod 500 to move up and down, the pull rod 500 can also be provided with an elongated limit groove 560 extending in the longitudinal direction of the pull rod, and a limit shaft 570 passes through the limit groove 560, and the limit shaft 570 can be fixed to the side wall of the second pipe 30.
