Description

Technical Field

[0001] The present invention relates to the technical field of infant carriers, and in particular to a child safety seat and a seat base. Background Art

[0002] Child safety seats need to be used correctly to play a role in protecting children. Child safety seats mainly include a seat body and a seat base. When in use, the seat base is connected to the car seat, and the seat body can be snapped onto the seat base in the forward or reverse direction. At present, most child safety seats do not have installation and use status warning devices. When users install them, whether the seat body and the seat base are snapped into place mainly depends on the subjective judgment of the operator, which can easily bring risks to children riding in the seats due to human errors. Other commercially available child safety seats have local indication functions, such as indication devices that display the connection status of the ISOFIX connector. However, the structures of these indication devices are generally more complicated, which increases the manufacturing difficulty and cost of child safety seats. Summary of the invention

[0080] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0081] like Figure 1 , Figure 2 and Fig.18 As shown, an embodiment of the present invention provides a child safety seat, which includes a seat base 1 and a seat body 2, wherein the seat body 2 is detachably connected to the seat base 1. The child safety seat has a simple structure, is convenient for users to observe the connection status between the seat base 1 and the seat body 2, and has a high safety factor.

[0082] like Figure 1-Figure 3 , Figure 6 , Fig.10 , Figure 18-Figure 20 As shown, the seat base 1 includes a clamping mechanism 100, a linkage mechanism 200, an indication mechanism 300, a release mechanism 400 and a mounting seat 101. The clamping mechanism 100 is used to clamp and lock the seat base 1 and the seat body 2. When the clamping mechanism 100 is released, the seat body 2 can be moved away from the seat base 1. The indication mechanism 300 includes an indication area, and the indication area is used to indicate the clamping state of the seat base 1 and the seat body 2. The linkage mechanism 200 is arranged between the clamping mechanism 100 and the indication mechanism 300. When the seat base 1 and the seat body 2 are clamped, the clamping mechanism 100 drives the indication mechanism 300 to change the indication state of the indication area to the first indication state. When the seat body 2 is moved away from the seat base 1, the indication state of the indication area is converted into the second indication state, so that the user can check the clamping state between the seat body 2 and the seat base 1 during installation or use to ensure that the two are installed in place. The release mechanism 400 is used to drive the clamping mechanism 100 to release.

[0083] like Figure 1-Figure 4 As shown, the mounting seat 101 is provided with a snap-fitting groove 102, the snap-fitting mechanism 100 is installed inside the mounting seat 101, and the locking hook 110 (described later) of the snap-fitting mechanism 100 protrudes into the snap-fitting groove 102. The bottom of the seat body 2 is provided with a snap-fitting rod 201 for snapping with the locking hook 110, and the snap-fitting locking of the seat base 1 and the seat body 2 is achieved by snapping the snap-fitting rod 201 into the snap-fitting groove 102 and locking with the locking hook 110; when the snap-fitting rod 201 is disengaged from the locking hook 110, the seat body 2 can be detached from the seat base 1.

[0084] In the present invention, four engaging grooves 102 can be provided on the mounting seat 101, two engaging grooves 102 are provided at the front and rear ends of the seat base 1, and the two engaging grooves 102 at each end are arranged at intervals. Figure 4 ), each engaging mechanism 100 is provided corresponding to one engaging slot 102, and the locking hook 110 of each engaging mechanism 100 protrudes into one engaging slot 102. Four or two engaging rods 201 are provided at the bottom of the seat body 2 to respectively engage in the four engaging slots 102. It is understandable that the number of the engaging slots 102 and the engaging rods 201 is not limited thereto and can be flexibly set according to needs.

[0085] like Figure 4-5 , Figure 8 , Figure 12-13 As shown, in the present invention, the structures of the four engaging mechanisms 100 are the same, and the two engaging mechanisms 100 arranged at the front end of the seat base 1 are symmetrically arranged, and the two engaging mechanisms 100 arranged at the rear end of the seat base 1 are symmetrically arranged. More specifically, a vertically extending fixing plate 103 is provided on the seat base 1, and each engaging mechanism 100 is correspondingly arranged on the fixing plate 103. The specific structure of one of the engaging mechanisms 100 is described in detail below by taking one of the engaging mechanisms 100 as an example.

[0086] like Figure 4 and Figure 5 As shown, the locking mechanism 100 includes a locking hook 110 , a fixing member 120 , a locking reset member 130 , a stopper 140 , a stopper reset member 150 , a sliding member 160 and a sliding reset member 170 .

[0087] Specifically, Figure 2 and Figure 5 As shown, the locking hook 110 is pivotally connected to the fixing plate 103 via a pivot shaft 113 and has an open position and a closed position. The locking hook 110 has a hook portion 111, which protrudes into the locking groove 102, and a locking groove 112 is formed below the hook portion 111. When the locking hook 110 is in the closed position, the locking rod 201 (such as Figure 3 When the locking hook 110 is in the open position, the latch rod 201 can be disengaged from the locking groove 112.

[0088] Specifically, Figure 5 and 13 As shown, the fixing member 120 is pivotally connected to the side of the locking hook 110 facing away from the fixing plate 103 through the pivot shaft 113, and the locking reset member 130 abuts against the fixing member 120 and the locking hook 110 respectively, and the locking reset member 130 constantly rotates the locking hook 110 to the open position.

[0089] Specifically, Figure 2 and Figure 5As shown, one end of the stopper 140 is pivotally connected to the fixed plate 103, and the pivot axis of the stopper 140 is parallel to the pivot axis 113 of the locking hook 110. The other end of the stopper 140 protrudes toward the fixing member 120 and is pivotally connected to the locking hook 110, and the stopper 140 can abut against the fixing member 120. The stopper reset member 150 is installed on the pivot axis of the stopper 140, and its two ends abut against the fixing plate 103 and the stopper 140 respectively, and the stopper reset member 150 constantly rotates the locking hook 110 to the open position. More specifically, the stopper 140 has a protruding portion 141 protruding toward the locking hook 110, and the protruding portion 141 protrudes into the engaging groove 102.

[0090] like Figure 2 , Figure 5 , Figure 8 As shown, during the process of the clamping rod 201 moving into the clamping groove 102, the clamping rod 201 pushes the hook portion 111 to make the locking hook 110 rotate by overcoming the elastic force of the locking reset member 130, and then the hook portion 111 rotates above the clamping rod 201. At the same time, during the clamping process, the clamping rod 201 also pushes the protrusion 141 of the stopper 140 to overcome the elastic force of the stopper reset member 150 and pivot toward the fixing member 120. During this process, the stopper 140 drives the end of the locking hook 110 connected thereto to move, and further drives the locking hook 110 to pivot toward its closed position. Under the dual action, the locking hook 110 can be quickly clamped on the clamping rod 201, making it faster and more labor-saving to clamp the clamping rod 201 into the locking hook 110, thereby realizing the rapid installation and locking of the seat body 2. Moreover, when the locking hook 110 is in the closed position, the stopper 140 abuts against the fixing member 120 to keep the locking of the locking hook 110 stable.

[0091] Correspondingly, during the process of the locking hook 110 pivoting to the open position, the block 140 is reset under the action of the block reset member 150, that is, the block 140 is pivoted upward, disengaged from the abutment against the fixing member 120 and at the same time drives the end of the locking hook 110 connected thereto to move, thereby generating a force for the locking hook 110 to pivot to the open position. With the joint action of the locking reset member 130 and the block reset member 150, the locking hook 110 can be quickly opened, making the detachment of the locking rod 201 more labor-saving and quick, thereby realizing the rapid removal of the seat body 2.

[0092] Specifically, the sliding member 160 is movably disposed in the mounting seat 101, and the sliding member 160 can abut against the four locking hooks 110 to simultaneously maintain the four locking hooks 110 in the open position or the closed position. Figure 4-5 shown.

[0093] like Figure 4 , Figure 10-13 , Figure 23-26As shown, the sliding member 160 is generally rectangular, and the four corners of the sliding member 160 are respectively provided with blocking portions 161, and the four blocking portions 161 respectively abut against each locking hook 110. The sliding member 160 has a locking position and a release position. When the sliding member 160 is in the locking position, its four blocking portions 161 simultaneously keep the four locking hooks 110 in the closed position. When the sliding member 160 slides to the release position along the direction indicated by the arrow F1, the four locking hooks 110 can be pivoted to their open positions, and then the four blocking portions 161 can abut against the locking hooks 110 again to keep them in the open position. The four locking hooks 110 are driven by one sliding member 160 to achieve locking and release synchronously, so that the structure is simplified. One end of the sliding reset member 170 is fixed to the sliding member 160, and the other end thereof is fixed to the mounting seat 101. The sliding reset member 170 constantly slides the sliding member 160 toward its locking position. Through the elastic force of the sliding reset member 170, the sliding member 160 constantly has a force abutting against the locking hook 110, so that the sliding member 160 can keep the locking hook 110 in the closed position or the open position.

[0094] like Figure 4 , Fig. 9 As shown, the sliding return member 170 can be a tension spring, but it is not limited thereto, and other elastic components can be selected. In the present invention, there are two sliding return members 170, which are arranged at intervals. The front end of each sliding return member 170 is connected to the sliding member 160, and the rear end thereof is connected to the mounting seat 101. The sliding return member 170 always has the force to pull the sliding member 160 toward the rear end of the mounting seat 101, that is, always makes the sliding member 160 move toward the rear end of the mounting seat 101, that is, Figure 4 , Fig.10 Therefore, the blocking portions 161 respectively abut against the front sides of the locking hooks 110. Of course, in another embodiment, as Figure 23-26 As shown, the sliding member 160 can also abut against the rear side of the locking hook 110 , and at this time, the force of the sliding restoration member 170 on the sliding member 160 is reversed.

[0095] Combination Figure 1-5 , Figure 8 , Figure 12-13 As shown, when the latch rod 201 pushes the hook portion 111 of the locking hook 110 downward to make it pivot, the hook portion 111 of the locking hook 110 pivots to the top of the latch rod 201, that is, the locking hook 110 rotates to the closed position. During this process, the locking hook 110 causes the locking reset member 130 to deform. When the locking hook 110 is in the closed position, the sliding member 160 resists the lower end of the locking hook 110 to keep it in the closed position. When the sliding member 160 slides to the unlocking position along the direction indicated by the arrow F1, the locking hook 110 loses the force of the sliding member 160, and the locking reset member 130 recovers its deformation and drives the locking hook 110 to rotate along the direction indicated by the arrow F1. Figure 12-13The locking hook 110 automatically pivots to the open position in the direction indicated by the middle arrow F3, so that the locking hook 110 is disengaged from the locking of the latch rod 201, allowing the latch rod 201 to move out of the latching slot 102 of the locking hook 110, allowing the seat body 2 to be removed from the seat base 1. For the locking hook 110 in the open position, the sliding member 160 will again abut against the lower end of the locking hook 110 under the action of the sliding return member 170 to keep it in the open position, so that the locking hook 110 cannot be closed.

[0096] In the present invention, the movement of the sliding member 160 drives the linkage mechanism 200 to move, thereby causing the indicating mechanism 300 to change the indicating state.

[0097] Specifically, Figure 6-7 , Figure 10-11 As shown, the linkage mechanism 200 includes a linkage member 210 , a linkage restoring member 220 , a rotating member 230 , a push button 240 and a push button restoring member 250 .

[0098] like Figure 6 , 7 As shown in FIG. 11 , the linkage member 210 is movably disposed in the mounting seat 101 and one end of the linkage member 210 is connected to the indication area. The linkage member 210 has a first indication position and a second indication position relative to each other. When the linkage member 210 is in different indication positions, the indication area is in different indication states. The linkage reset member 220 is disposed between the linkage member 210 and the mounting seat 101. The linkage reset member 220 constantly moves the linkage member 210 to its second indication position. Fig.10 , 16 shown.

[0099] like Figure 9-11 , Fig.17 As shown, the rotating member 230 is generally an L-shaped sheet structure, and the approximately middle part of the rotating member is pivoted on the mounting seat 101. The rotating member 230 has a first connecting end 231 and a second connecting end 232. The first connecting end 231 and the second connecting end 232 are arranged at an angle relative to the pivot axis of the rotating member 230. The first connecting end 231 is pivoted to the linkage 210, and the second connecting end 232 has a vertically extending abutment portion 233, that is, the abutment portion 233 extends along the axial direction of the pivot axis of the rotating member 230. The abutment portion 233 is located below the push button 240 and abuts therewith. When the push button 240 acts on the abutment portion 233, the rotating member 230 can be driven to rotate. In addition, the sliding member 160 has a downwardly protruding push protrusion 162, and the push protrusion 162 is slidably matched with the upper end of the push button 240. When the sliding member 160 slides, the push protrusion 162 pushes the push button 240 to slide downward, that is, along the Fig.11 Slide in the opposite direction as indicated by the middle arrow F2.

[0100] like Fig. 9 , 11As shown in FIGS. 15A and 15B , the upper end of the push button 240 has a protrusion 241 protruding along its radial direction. The push button reset member 250 is sleeved outside the push button 240 and abuts against the mounting seat 101 and the protrusion 241 respectively. The push button reset member 250 constantly moves the push button 240 in the opposite direction of being pushed by the locking mechanism 100.

[0101] Combination Figure 1 , 16 As shown in FIG. 17 , the indication area of ​​the indication mechanism 300 is specifically divided into a first indication area 310 and a second indication area 320, both of which are arranged at one end of the linkage member 210 away from the rotating member 230. The first indication area 310 and the second indication area 320 can be set to different colors, patterns or other warning signs. For example, in this embodiment, the first indication area 310 is set to green and the second indication area 320 is set to red, so as to clearly indicate the state of the locking hook 110.

[0102] See also Figure 1 , Figure 4 The indicating mechanism 300 further includes an indicating window 330 disposed at the front end of the mounting seat 101, and the first indicating area 310 and the second indicating area 320 are disposed below the indicating window 330. When the linking member 210 moves, the first indicating area 310 and the second indicating area 320 are selectively positioned opposite the indicating window 330, that is, the indicating area is switched between the first indicating state and the second indicating state, wherein the first indicating area 310 corresponds to the first indicating state, and the second indicating area 320 corresponds to the second indicating state.

[0103] Recombination Figure 10-11 , 16-17, during the engagement of the seat base 1 and the seat body 2, the sliding member 160 moves along Fig.10 , Fig.14 The push button 240 moves in the reverse direction indicated by the middle arrow F1, and the push projection 162 on the sliding member 160 presses the push button 240 downward, and the push button 240 moves downward, that is, along the Fig.11 , Fig.15 The push button 240 moves in the reverse direction as indicated by the middle arrow F2. During this process, the push button reset member 250 is compressed and deformed. The push button 240 pushes the abutment portion 233 of the rotating member 230 during the downward movement, so that the rotating member 230 moves along its pivot axis. Figure 7 , Fig.11 The first connecting end 231 is pivoted in the direction indicated by the middle arrow F5, thereby swinging the first connecting end 231 and driving the linking member 210 along the Figure 10-11The seat body 2 is slid in the direction indicated by the middle arrow F4, during which the linkage member 210 pushes the linkage reset member 220 to deform it. When the seat body 2 is fully engaged with the seat base 1, the locking hook 110 pivots to the closed position, the sliding member 160 is in the locked position and the push button 240 is kept in a lower position, and the linkage member 210 slides to the first indication position, that is, the first indication area 310 (green area) is opposite to the indication window 330, that is, the indication area is in the first indication state, indicating that the seat body 2 is fully engaged with the seat base 1.

[0104] When the seat body 2 and the seat base 1 are released from engagement, the locking hook 110 is released. Fig.10 The push button 240 moves in the direction indicated by the middle arrow F1, and the push projection 162 on the sliding member 160 is separated from the push button 240. The push button 240 moves along the push button reset member 250 under the action of the push button reset member 250. Fig.11 At the same time, the linkage reset member 220 recovers its deformation and acts on the linkage member 210 to make it move along Figure 10-11 Slide in the opposite direction indicated by the middle arrow F4. When the linkage 210 slides to the second indication position, the second indication area 320 (red area) is opposite to the indication window 330, that is, the indication state of the indication area is converted into the second indication state, indicating that the seat base 1 and the seat body 2 are not connected.

[0105] In one embodiment, Figure 4 , Figure 6-Figure 11 , Figure 14-15 As shown, the lock release mechanism 400 includes a driving member 410 , a first push rod 420 , a second push rod 430 , a driving reset member 440 , a pull handle 450 and a pulling member 460 .

[0106] like Figure 4 , Figure 6-Figure 11 , Figure 14-15 As shown, the driving member 410 is movably mounted on the mounting seat 101 and has a first position and a second position relative to each other. The first push rod 420 is movably arranged and slidably cooperates with the driving member 410. The moving direction of the first push rod 420 is staggered with the moving direction of the driving member 410. The second push rod 430 is inserted into the push button 240 and is movably arranged. The two ends of the second push rod 430 respectively abut against the first push rod 420 and the sliding member 160. The first push rod 420 drives the second push rod 430 to move in the same direction. Figure 7 , Figure 10-11 , Figure 14-15When moving in the direction indicated by the middle arrow F4, the first push rod 420 can be driven to move in the direction indicated by the arrow F2 to push the second push rod 430, so that the second push rod 430 moves in the direction indicated by the arrow F2 to drive the sliding member 160 to move in the direction indicated by the arrow F1 and disengage from the interference with the locking hook 110, so that the locking hook 110 can pivot to the open position.

[0107] like Figure 7 , Fig. 9 As shown, the driving member 410 is provided with staggered driving inclined grooves 411 and sliding grooves 412. The sliding grooves 412 extend along their sliding direction. The mounting seat 101 is provided with a mounting block 104. The mounting block 104 is provided with a third guide column 105. The third guide column 105 can be inserted into the sliding groove 412 and can slide along the sliding groove 412, thereby realizing the sliding connection between the driving member 410 and the mounting block 104. The first push rod 420 is slidably connected in the mounting block 104. The first push rod 420 is provided with a first guide column 421. The first guide column 421 is inserted into the driving inclined groove 411 and can slide along the driving inclined groove 411, thereby realizing the sliding connection between the first push rod 420 and the driving member 410. The driving member 410 is along Figure 7 , Figure 10-11 , Figure 14-15 When sliding from the first position to the second position in the direction indicated by the middle arrow F4, the driving inclined groove 411 acts on the first guide column 421 to drive the first push rod 420 to move upward in the direction indicated by the arrow F2. The driving reset member 440 is arranged between the driving member 410 and the mounting block 104. When the driving member 410 slides to the second position, the driving reset member 440 is compressed, so the driving reset member 440 constantly moves the driving member 410 to its first position.

[0108] like Fig. 9 , Fig.15 As shown, the second push rod 430 is slidably connected to the mounting base 101 through a pin, and a driving inclined surface 431 is provided at the end of the second push rod 430 away from the first push rod 420, and a driven inclined surface 163 matching the driving inclined surface 431 is provided approximately in the middle of the sliding member 160. When the second push rod 430 moves upward in the direction indicated by the arrow F2, the driving inclined surface 431 acts on the driven inclined surface 163 to drive the sliding member 160 to move in the direction indicated by the arrow F1.

[0109] like Figure 1 , Figure 4 , Figure 6-7As shown, the pull handle 450 is disposed at the front end of the seat base 1 and exposed on the upper surface of the seat base 1 for user operation. The traction member 460 is connected between the pull handle 450 and the driving member 410. When the pull handle 450 is operated, the driving member 410 is pulled to slide from the first position to the second position by the traction member 460. The traction member 460 may be a steel wire rope, but is not limited thereto, and may also be other similar components with toughness and strength.

[0110] Combine the following Figure 4 , Figure 6-Figure 11 , Figure 14-15 As shown, when the driving member 410 is in the first position, the first push rod 420 is retracted into the driving member 410. Figure 7 , Fig.11 , Fig.15 As shown, the driving reset member 440 is in a natural state. At this time, the sliding member 160 is in a locked position and the locking hook 110 is kept in its closed position. Pulling the handle 450 causes it to pull the driving member 410 along the pull member 460. Figure 7 , Figure 10-11 , Figure 14-15 The first push rod 420 is driven by the driving inclined groove 411 to slide upward along the direction indicated by the arrow F2, and the first push rod 420 then pushes the second push rod 430 to slide upward along the direction indicated by the arrow F2. The driving inclined surface 431 on the second push rod 430 acts on the driven inclined surface 163 to drive the sliding member 160 to move along the direction indicated by the arrow F1 until the sliding member 160 moves to the unlocking position. During the sliding process of the sliding member 160, the sliding reset member 170 is further stretched. When the sliding member 160 moves to the unlocking position, the locking hook 110 can automatically pivot and open under the action of the locking reset member 130.

[0111] After releasing the pull handle 450, the driving member 410 is reset to the first position under the action of the driving reset member 440, thereby driving the first push rod 420 to slide downward in the opposite direction of the direction indicated by the arrow F2, and then causing the second push rod 430 to slide downward in this direction. The sliding member 160 loses the force of the second push rod 430, and is therefore reset under the action of the sliding reset member 170, thereby abutting against the locking hook 110 again to keep it in the open position.

[0112] In another embodiment, Figure 22-34 As shown, the release mechanism 400 includes a first pivoting member 410 a , a first pushing member 420 a , a second pushing member 430 a , a second pivoting member 440 a , a pivoting restoring member 450 a , a handle 450 and a pulling member 460 .

[0113] Specifically, the first pivot member 410a is substantially in a triangular sheet-like structure, and substantially three vertices of the first pivot member 410a respectively have a first pivot end 411a, a driving end 412a and a free end 413a. Fig.28 , 30 The first pivot end 411a is pivoted to the mounting seat 101 and connected to one end of the traction member 460. The first pivot member 410a can rotate to the third position or the fourth position with the first pivot end 411a as the center. The mounting seat 101 is provided with a mounting tube 106. The mounting tube 106 is provided with a Fig.28 , 30 The first push member 420a is generally columnar and slidably disposed in the mounting tube 106. The first push member 420a is provided with a second guide column 421a. Fig.32 , 34 As shown, the second guide post 421a is inserted into the driving guide groove 107 and moves along the driving guide groove 107, thereby realizing the sliding connection between the first push member 420a and the mounting tube 106. The second guide post 421a passes through the driving guide groove 107 and the mounting tube 106 and is connected to the driving end 412a. Fig. 27 , 29 When the first pivot member 410a rotates from the third position to the fourth position in the direction indicated by the arrow F8, the driving end 412a of the first pivot member 410a moves upward along the driving guide groove 107 in the direction indicated by the arrow F2, and at the same time, the driving guide groove 107 acts on the second guide column 421a to drive the first push member 420a to move upward along the direction indicated by the arrow F2, as shown in FIG. Fig.32 , 34 shown.

[0114] like Fig.32 , 34 As shown, the second pushing member 430a is movably arranged between the first pushing member 420a and the sliding member 160. The second pushing member 430a has a mounting groove 431a, and the second pivot member 440a is rotatably arranged in the mounting groove 431a. The outer side of the bottom wall of the mounting groove 431a abuts against the first pushing member 420a. The second pivot member 440a is roughly a triangular sheet structure. The second pivot member 440a has a second pivot end 441a and an abutting end 442a at approximately two vertices, respectively. The second pivot end 441a is pivotally connected to the side wall of the mounting groove 431a, and the abutting end 442a is used to abut against the sliding member 160. Specifically, an abutting protrusion 164 can be provided at a position approximately in the middle of the sliding member 160, and the abutting end 442a is used to abut against the abutting protrusion 164. When the first pivot member 410a is subjected to force along Fig. 27 , 29When the first push member 420a rotates in the direction indicated by the arrow F8, the first push member 420a can be driven to move in the direction indicated by the arrow F2 to push the second push member 430a, so that the second push member 430a pushes the second pivot member 440a along the Fig.32 , 34 The abutting end 442a is rotated in the direction indicated by the arrow F9, so that the abutting end 442a pushes the abutting protrusion 164, so as to drive the sliding member 160 to move in the opposite direction indicated by the arrow F1 and to break away from the abutment with the locking hook 110, so that the locking hook 110 can be pivoted to the open position, as shown in FIG. Figure 23-26 shown.

[0115] like Fig.32 , 34 As shown, the pivoting restoration member 450a is respectively in contact with the first pivoting member 410a and the mounting seat 101. Fig. 27 , 29 During the rotation in the direction indicated by the middle arrow F8, the pivoting restoration member 450a is compressed, so the pivoting restoration member 450a always makes the first pivoting member 410a always have a Fig. 27 , 29 Rotate in the opposite direction of the direction indicated by the arrow F8 to achieve the tendency of resetting.

[0116] like Fig.19 , 20 As shown, there are two handles 450, which are respectively arranged on both sides of the mounting seat 101 and exposed on the side surface of the mounting seat 101, so as to facilitate the user's operation. The design of the handle 450 being located at the side of the mounting seat 101 is more convenient to operate than the design of the handle 450 being located at the front end of the mounting seat 101 in the aforementioned embodiment, because the front end of the mounting seat 101 is often difficult to reach due to the obstruction of the seat body 2 and the front car seat, while the side of the mounting seat 101 is directly opposite to the operator, so it is easier to operate.

[0117] Fig. 20 , 27, 29, there are two traction members 460, and each traction member 460 is connected between the pull handle 450 on one side and the first pivot member 410a. When the pull handle 450 is operated, the first pivot member 410a is driven to rotate from the third position to the fourth position by pulling through the traction member 460. In this embodiment, the first pivot member 410a can be driven by pulling through the traction member 460 by operating the pull handle 450 upward. Of course, in other embodiments, the pull handle 450 can also be operated in other ways. Among them, the traction member 460 can be a steel wire rope, but it is not limited to this, and it can also be other similar components with toughness and strength. Specifically, a guide member 108 is provided on the mounting seat 101, and the guide member 108 has an arc-shaped guide portion. One end of the traction member 460 is connected to the pull handle 450 on either side, and the other end of the traction member 460 enters the mounting seat 101 along the direction indicated by the arrow F6 (i.e., the horizontal width direction of the mounting seat 101), and under the guidance of the guide member 108, bypasses the guide part and connects to the first pivot member 410a along the direction indicated by the arrow F7 (i.e., the length direction of the mounting seat 101).

[0118] Combine the following Figure 21-34 As shown, when the first pivot member 410a is in the third position, the first push member 420a is in a relatively lower position in the installation tube 106, such as Fig.32 As shown, the pivoting reset member 450a is in a natural state. At this time, the sliding member 160 is in a locked position and the locking hook 110 is kept in its closed position, such as Fig.30 Pull the handle 450 to pull the first pivot member 410a along the traction member 460. Fig.29 The first pivot member 410a rotates in the direction indicated by the middle arrow F8. During this process, the first pivot member 410a acts on the pivot reset member 450a to deform it. During the rotation of the first pivot member 410a, the first push member 420a is driven to slide upward in the direction indicated by the arrow F2 through the driving guide groove 107. The first push member 420a then pushes the second push member 430a to slide upward in the direction indicated by the arrow F2. The side wall or bottom wall of the mounting groove 431a of the second push member 430a pushes the second pivot member 440a to slide upward in the direction indicated by the arrow F2. Fig.32 The abutting end 442a is rotated in the direction indicated by the arrow F9, so that the abutting end 442a pushes the abutting protrusion 164 to drive the sliding member 160 to move in the opposite direction indicated by the arrow F1 until the sliding member 160 moves to the unlocking position, as shown in FIG. Fig.34 As shown. During the sliding process of the sliding member 160, the sliding reset member 170 is further stretched. When the sliding member 160 moves to the unlocking position, the locking hook 110 can automatically pivot and open under the action of the locking reset member 130.

[0119] After the handle 450 is released, the first pivot member 410a is reset to the third position under the action of the pivot reset member 450a, thereby driving the first push member 420a to slide downward in the direction opposite to the direction indicated by the arrow F2, thereby causing the second push member 430a to slide downward in the direction as well. Fig.32 The second pivot member 440a rotates in the direction opposite to the direction indicated by the arrow F9 and no longer pushes against the abutting protrusion 164. Fig.32 The sliding member 160 loses the force of the second pivoting member 440a, and is thus reset under the action of the sliding reset member 170, thereby abutting against the locking hook 110 again to keep it in the open position, as shown in FIG. Fig.28 shown.

[0120] Combination Figure 1-Figure 34 As shown, the working principle of the seat base 1 of the child safety seat of the present invention is described.

[0121] When the seat body 2 is not connected to the seat base 1, the locking hook 110 is located under the elastic force of the locking reset member 130. Figure 5-6 The open position shown, at the same time, the slide 160 is located Figure 6 In the unlocking position shown, the linkage member 210 is located at the second indicating position, that is, the second indicating area 320 (red area) is opposite to the indicating window 330 .

[0122] When the locking rod 201 of the seat body 2 is inserted into the locking groove 102 on the seat base 1, the locking rod 201 will push the hook portion 111 of the locking hook 110 downward to make it pivot around the pivot axis 113, thereby driving the locking hook 110 to overcome the elastic force of the locking reset member 130 and rotate the hook portion 111 to the top of the locking rod 201, thereby locking the locking rod 201 moved into the locking groove 102. After the locking hook 110 pivots around its pivot axis 113, the stopper 140 abuts against the fixing member 120 to keep the locking of the locking hook 110 stable. After the locking hook 110 is rotated and engaged with the locking rod 201, the sliding member 160 will slide along the sliding reset member 170 under the elastic force of the sliding reset member 170. Figure 4 , Figure 6 , Figure 10-11 , Fig.14 The locking hook 110 is abutted against the locking hook 110 again to keep the locking hook 110 in the closed position.

[0123] During the sliding process, the sliding member 160 will cause the pushing protrusion 162 below to push the push button 240 along the Fig.11 , Figure 14-15 The push button 240 moves downward in the opposite direction of the direction indicated by the middle arrow F2. During the movement of the push button 240, the push button 240 acts on the abutment portion 233 of the rotating member 230, causing the rotating member 230 to rotate along its pivot axis. Fig.11The first connecting end 231 of the rotating member 230 is pivoted in the direction indicated by the middle arrow F5, thereby swinging the first connecting end 231 of the rotating member 230 to drive the linking member 210 to move along the Figure 10-11 , Fig.16 The push button 240 slides in the direction indicated by the middle arrow F4, so that the first indication area 310 (green area) faces the indication window 330, that is, the seat body 2 is indicated to be engaged with the seat base 1. In addition, the push button reset member 250 is pressed to deform during the downward movement of the push button 240, and the linkage reset member 220 is pressed to deform during the sliding of the linkage member 210.

[0124] When the seat body 2 needs to be removed from the seat base 1, in one embodiment, the operator pulls the handle 450, and the handle 450 drives the driving member 410 to move along the seat body 2. Figure 7 , Figure 10-11 , Figure 14-15 The first push rod 420 then pushes the second push rod 430 to continue moving in the direction indicated by the arrow F2. The driving inclined surface 431 of the second push rod 430 acts on the driven inclined surface 163 of the sliding member 160, driving the sliding member 160 to move in the direction indicated by the arrow F1, so that the four blocking portions 161 thereon are disengaged from the interference with the locking hook 110. At this time, the locking hook 110 automatically pivots to its open position under the action of the locking reset member 130, so that the hook portion 111 rotates away from the engaging groove 102. At this time, the seat body 2 can be lifted from the seat base 1 to achieve disassembly.

[0125] During the movement of the sliding member 160 in the direction indicated by the arrow F1, the push projection 162 of the sliding member 160 gradually separates from the push button 240 and loses the downward force on the push button 240, so the push button 240 is reset upward under the action of the push button reset member 250, that is, the push button 240 is reset upward along the direction indicated by the arrow F1. Fig.11 , Figure 14-15 The connecting member 210 moves upward in the direction indicated by the middle arrow F2, thereby losing the force on the abutment portion 233 of the rotating member 230. At this time, the connecting member 210 can be reset under the action of the connecting reset member 220, that is, it slides in the opposite direction of the direction indicated by the arrow F4, so that its second indication area 320 (red area) is opposite to the indication window 330 again, indicating that the seat body 2 is not engaged with the seat base 1.

[0126] In another embodiment, the operator operates the handle 450, and the handle 450 drives the first pivot member 410a to move along the Fig. 27 , 29The first pivot member 410a rotates toward the fourth position in the direction indicated by the middle arrow F8. During this process, the first pivot member 410a drives the first push member 420a to move upward in the direction indicated by the arrow F2. The first push member 420a then pushes the second push member 430a to continue moving in the same direction. The second push member 430a pushes the second pivot member 440a, so that the second pivot member 440a moves upward. Fig.32 , 34 The seat body 2 can be disassembled by rotating the seat body 20 from the seat base 102 through the locking mechanism 110. The seat body 2 can be disassembled by rotating the seat body 20 from the seat base 102 through the locking mechanism 110.

[0127] During the reverse movement of the sliding member 160 in the direction indicated by the arrow F1, the push projection 162 of the sliding member 160 gradually separates from the push button 240 and loses the downward force on it, so the push button 240 is reset upward under the action of the push button reset member 250, that is, the push button 240 is reset along the Fig.28 , Fig.30 The connecting member 210 moves upward in the direction indicated by the middle arrow F2, thereby losing the force on the abutment portion 233 of the rotating member 230. At this time, the connecting member 210 can be reset under the action of the connecting reset member 220, that is, it slides in the opposite direction indicated by the arrow F4, so that its second indication area 320 (red area) is opposite to the indication window 330 again, indicating that the seat body 2 is not engaged with the seat base 1.

[0128] In summary, the seat base 1 of the present invention is provided with a linkage mechanism 200 between the snap mechanism 100 and the indicating mechanism 300, and the snap connection between the seat base 1 and the seat body 2 is realized through the snap mechanism 100, and when the snap mechanism 100 is snap-connected or snap-disconnected with the seat body 2, the linkage mechanism 200 can drive the indicating drive to present different indicating states. In this way, the user can conveniently check the connection state between the seat base 1 and the seat body 2, which is more convenient and safer to use. At the same time, the structure of the seat base 1 is simple, and the manufacturing difficulty and manufacturing cost are both low.

To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention.
