Description

Technical Field

[0001] This application relates to the technical field of car seats, and in particular to a car seat base and a child safety seat. Background Technology

[0002] A child safety seat is a seat attached to a car seat and is designed specifically for children of different weights and ages to protect them while the vehicle is in motion. In the event of a car collision or sudden deceleration, a child safety seat can absorb and disperse the energy of the impact, reducing the direct impact on the child's body. Safety seats also restrict the child's movement within the vehicle, providing necessary support, thereby helping to reduce the risk of serious injury or death.

[0003] Generally, a child safety seat consists of a base and a seat body. The base directly contacts the car seat to support the seat body. Below the base are support legs that abut against the car floor, increasing the seat's stability and safety. To make securing and storing the support legs easier, some child safety seats have a support leg receiving slot under the base. One end of the support leg is hinged to the front of the base, and when not in use, the support leg is folded into the receiving slot. However, in use, the support leg needs to extend to the front of the safety seat to contact the car floor mat. Therefore, in these safety seats, the upper end of the support leg must extend beyond the base to reach the front of the safety seat. This design creates a protrusion at the upper end of the support leg, which is prone to bumping during transport and inconvenient to use. Utility Model Content

[0004] To address the problem that the protrusion formed by the upper end of the support leg extending outward from the front of the base causes inconvenience in the use of child safety seats, this application provides a safety seat base and a child safety seat.

[0005] This application provides a child seat base, which adopts the following technical solution:

[0006] A child safety seat base includes a support base and a support leg, the support leg being pivotally connected to the support base, the bottom of the support base having a first receiving groove for accommodating the support leg, and further comprising:

[0007] A reinforcing rod is fixed inside the support base;

[0008] A fixing tube is fixedly connected to one end of the reinforcing rod. The first receiving groove is formed by the housing at the bottom of the support base recessed into the support base. The fixing tube abuts against the side wall of the first receiving groove and is clamped between the reinforcing rod and the side wall of the first receiving groove.

[0009] A telescopic tube is slidably inserted into a fixed tube and can slide from one end of the fixed tube. A locking element is provided between the telescopic tube and the fixed tube, which locks the telescopic tube onto the fixed tube after it extends out.

[0010] A sliding member is fixedly connected to the end of the telescopic tube away from the reinforcing rod, and the upper end of the support leg is hinged to the sliding member;

[0011] A sliding groove is provided at the bottom of the support base to accommodate the sliding member. One end of the sliding groove is connected to the first receiving groove, and the other end of the sliding groove has an opening for the sliding member to slide to the front side of the support base.

[0012] By adopting the above technical solution, the support leg is hinged to the sliding member, and the telescopic tube can slide and lock within the fixed tube. The sliding member is fixedly connected to the telescopic tube to achieve sliding. Compared with the prior art, the hinge point of the support leg can move with the sliding member. Therefore, when the support leg is retracted, the hinge point of the support leg can move with the sliding member to the sliding groove under the support seat, thus enabling the support leg to be hidden at the bottom of the support seat in the retracted state. This reduces the risk of bumps caused by the outward protrusion of the support leg in the traditional structure, improves the overall flatness of the base appearance, and enhances the convenience of using the child safety seat. One side of the fixed tube abuts against the wall of the first receiving groove, and a reinforcing rod is fixed to the other side of the fixed tube. The composite support structure formed by the reinforcing rod and the fixed tube improves the stability and connection strength of the connection between the support leg and the support seat while achieving the storage function.

[0013] Preferably, the locking member includes a stop and an elastic ejector. The stop is fixed to the end of the telescopic tube away from the sliding member. The elastic ejector is disposed on the telescopic tube. When the telescopic tube is in the retracted state, the stop is located outside the fixed tube, and the fixed tube restricts the elastic ejector from popping out. When the telescopic tube extends to the point where the stop abuts against the end face of the fixed tube, the elastic ejector pushes out to restrict the telescopic tube from retracting.

[0014] Preferably, the stop includes a fixed mounting part and a stop part, the mounting part being fitted and fixed inside the telescopic tube, and the stop part abutting against the end face of the telescopic tube.

[0015] Preferably, the support leg includes a fixed leg and a telescopic leg. The upper end of the fixed leg is hinged to the sliding member, and the telescopic leg is slidably fitted onto the lower end of the fixed leg. The telescopic leg can be adjusted to extend and retract and is fixed to the fixed leg to adjust the length of the support leg.

[0016] Preferably, the telescopic leg is provided with a plurality of position holes, and the fixed leg is provided with an adjusting pin. The adjusting pin includes a plug, a fixing part, and a pressing part. The fixing part is fixed to the fixed leg. The plug is inserted into the position hole to fix the telescopic leg. The plug is fixed to one end of the fixing part, and the pressing part is fixed to the other end of the fixing part. Pressing the pressing part causes one end of the fixing part connected to the plug to tilt upward, and the plug disengages from the position hole.

[0017] Preferably, the first receiving groove is provided with a limiting buckle on the groove wall, and the limiting buckle restricts the support leg from coming out of the first receiving groove.

[0018] Preferably, the lower end of the support leg is provided with a support foot, the width of the support foot is greater than the width of the support leg, a positioning key is provided through the support foot, the bottom end of the positioning key protrudes away from the support foot, the other end of the positioning key abuts against an indicator plate, a viewing window is provided on the support foot for observing the indicator plate, and when the bottom end of the positioning key is pressed, it pushes the indicator plate upward to indicate the installation status of the support foot.

[0019] Preferably, the bottom of the support base is provided with a second receiving groove adapted to the support leg, the second receiving groove is connected to the first receiving groove, and the support leg abuts against the groove wall of the second receiving groove to restrict the support leg from sliding along the length direction of the first receiving groove.

[0020] Preferably, one side of the support base extends upward to form a support portion, which is used to support the backrest of the seat body of the safety seat.

[0021] In summary, this application includes at least one of the following beneficial technical effects:

[0022] With its compact structure and concealed support legs, the support legs can be hidden at the bottom of the base when folded, reducing the risk of bumps and knocks caused by the protruding hinge points of the support legs in traditional structures.

[0023] The locking is reliable, and the support and connection strength are high. The combination design of the stop and the elastic ejector achieves a two-level locking function. The fixing tube is clamped between the reinforcing rod and the groove wall of the first receiving groove. The groove wall of the first receiving groove can share part of the load, thereby improving the overall support strength.

[0024] It saves space and has good adaptability. The nested structure of fixed legs and telescopic legs can shorten the length of the support legs when stored, saving storage space. At the same time, the length of the support legs is adjustable to adapt to different car seats. Attached Figure Description

[0034] The following is in conjunction with the appendix Figure 1-8 This application will be described in further detail.

[0035] This application discloses a child safety seat base. (Refer to...) Figure 1 and Figure 2The child safety seat base includes a support base 1, a support frame 2, a sliding mechanism 3, and support legs 4. The support base 1 directly contacts the car seat and supports the seat body. The support frame 2 is fixed to the bottom of the support base 1 and connects the support base 1 and the support legs 4. The upper end of the support legs 4 is hinged to the sliding mechanism 3, which is slidably connected to one end of the support frame 2. The sliding mechanism 3 allows the hinge point of the support legs 4 to slide. A locking element connects the sliding mechanism 3 and the support frame 2, fixing them relatively. The bottom of the support base 1 also has a first receiving groove 11 and a sliding groove 12 that communicate with each other. The first receiving groove 11 is used to receive the support legs 4, and the sliding groove 12 provides sliding space and storage space for the sliding mechanism 3. When the support leg 4 is extended, rotate the support leg 4 out of the first receiving groove 11, and then pull the sliding mechanism 3 outward so that the hinge point of the support leg 4 is placed on the front side of the support base 1. At this time, the locking member locks the sliding mechanism 3 in the predetermined position, and then adjust the support leg 4 to abut against the car floor mat. When the support leg 4 is retracted, release the locking member, push the sliding mechanism 3 back to its original position, and then rotate the support leg 4 to be retracted into the first receiving groove 11.

[0036] Reference Figure 2 and Figure 3 The support frame 2 includes a reinforcing rod 21 and a fixing tube 22. The reinforcing rod 21 is fixed inside the support base 1 and fixed to the lower housing of the support base 1. One end of the reinforcing rod 21 is connected to the ISOFIX assembly on the support base 1. The fixing tube 22 is fixedly connected to the other end of the reinforcing rod 21. The fixing tube 22 and the reinforcing rod 21 can be connected by welding or bolting. The reinforcing rod 21 provides a stable installation base for the fixing tube 22 and prevents structural deformation when the support leg 4 is deployed. Preferably, two reinforcing rods 21 and two fixing tubes 22 are provided respectively. The first receiving groove 11 is formed by the lower shell of the support base 1 recessed into the support base 1. Correspondingly, a protrusion 13 is formed in the support base 1. The two sides of the protrusion 13 are the groove walls of the first receiving groove 11. The fixing tube 22 abuts against the two sides of the protrusion 13. The reinforcing rod 21 is fixed on the side of the fixing tube 22 away from the protrusion 13. The fixing tube 22 is clamped between the reinforcing rod 21 and the protrusion 13. This clamping connection structure can effectively distribute the load transmitted by the support leg 4.

[0037] Reference Figure 2 and Figure 4The sliding mechanism 3 includes a telescopic tube 31 and a sliding member 32. The telescopic tube 31 is slidably inserted into the fixed tube 22 and can extend and retract from one end of the fixed tube 22. A locking member is provided between the fixed tube 22 and the telescopic tube 31 to fix the telescopic tube 31 relative to the fixed tube 22 after it extends out. The sliding member 32 is fixed to the end of the telescopic tube 31 away from the reinforcing rod 21. The sliding member 32 slides by connecting to the telescopic tube 31. The upper end of the support leg 4 is hinged to the sliding member 32. The sliding groove 12 provides sliding space and storage space for the sliding member 32. One end of the sliding groove 12 is connected to the first receiving groove 11, and the other end of the sliding groove 12 has an opening. The opening allows the sliding member 32 to slide out of the sliding groove 12 to the front side of the support base 1. The support leg 4 moves its hinge point by sliding the telescopic tube 31 and the sliding member 32, so as to meet the different requirements of the hinge point position of the support leg 4 in the retracted state and the unfolded state. When the support leg 4 and the sliding member 32 are retracted, they can be retracted to the bottom of the support base 1, thereby overcoming the problem of the outward protrusion of the hinge point of the support leg 4.

[0038] Reference Figure 4 and Figure 5 The locking element includes a stop block 311 and an elastic ejector 312. The stop block 311 is fixed to the end of the telescopic tube 31 away from the sliding member 32. Specifically, the stop block 311 can be a plastic part that is clamped to the end of the telescopic tube 31 by an interference fit to axially limit the extension direction of the telescopic tube 31. The stop block 311 abuts against the end face of the fixed tube 22 to indicate that the telescopic tube 31 and the sliding member 32 have slid into place. In a specific embodiment, the stop block 311 includes a mounting part 313 and a stop part 314 that are fixedly connected. The mounting part 313 and the stop part 314 are preferably integrally formed. The stop part 314 is located at one end of the mounting part 313, and the other end of the mounting part 313 is inserted and fixed inside the telescopic tube 31. The mounting part 313 and the telescopic tube 31 can be fixed by an interference fit or bolts. The size of the stop part 314 is larger than the size of the through hole of the fixed tube 22 so that the stop part 314 can abut against the end face of the fixed tube 22. Compared to the existing technology that uses snap-fit ​​protrusions for limiting, the stop block 311 can withstand greater impact loads.

[0039] The elastic ejector 312 is mounted on the telescopic tube 31, and can be an elastic element with elastic deformation capability, such as a spring plunger or an elastic metal sheet. When the telescopic tube 31 is in the retracted state, the elastic ejector 312 is located in the gap between the outer wall of the telescopic tube 31 and the inner wall of the fixed tube 22. At this time, the elastic ejector 312 is compressed and undergoes elastic deformation, exhibiting a tendency to rebound. Simultaneously with the telescopic tube 31 sliding into position, the elastic ejector 312 slides out from the fixed tube 22. Having broken free from the constraint of the inner wall of the fixed tube 22, the elastic ejector 312 pops out and abuts against the end face of the fixed tube 22 away from the stop 311, thus restricting the retraction of the telescopic tube 31. Therefore, the telescopic tube 31 is restricted by the stop 311 in the extension direction and by the elastic ejector 312 in the retraction direction, thus fixing the telescopic tube 31 relatively to the fixed tube 22.

[0040] The support leg 4 includes a fixed leg 41 and a telescopic leg 42. The upper end of the fixed leg 41 is hinged to the sliding member 32, and the telescopic leg 42 is slidably fitted onto the lower end of the fixed leg 41. The telescopic leg 42 can be adjusted to extend and retract along its length and is fixed to the fixed leg 41, thereby adjusting the length of the support leg 4 to accommodate car seats of different heights. In one specific embodiment, the telescopic leg 42 has several stop holes 421 along its length. These stop holes 421 are spaced apart to provide multiple fixed positions for length adjustment. The fixed leg 41 has an adjusting pin 43, which is inserted into the stop holes 421 to restrict the sliding of the telescopic leg 42 and fix the telescopic leg 42 and the fixed leg 41. Specifically, the adjusting pin 43 is an elastic component made of metal sheet by stamping or plastic injection molding. The adjusting pin 43 includes a plug part 431, a fixing part 432 and a pressing part 433. The fixing part 432 is fixed to the fixing leg 41. The plug part 431 is a protruding structure fixed to one end of the fixing part 432 for inserting into the gear hole 421. The pressing part 433 is fixed to the other end of the fixing part 432. When pressure is applied to the pressing part 433, a lever effect is generated. Specifically, when the length of the support leg 4 needs to be adjusted, press the pressing part 433 so that the fixing part 432 acts as a fulcrum to generate a lever effect. One end of the fixing part 432 connected to the pressing part 433 is pressed down, and the other end of the fixing part 432 is raised so that the insertion part 431 is disengaged from the stop hole 421. At this time, the telescopic leg 42 can slide along the fixing leg 41. When it moves to the target position, release the pressing part 433. The insertion part 431 rebounds under the elasticity of the material and automatically inserts into the corresponding stop hole 421 to complete the locking.

[0041] Reference Figure 1 and Figure 2The first receiving groove 11 is provided with a limiting buckle 111 on the groove wall. The limiting buckle 111 can be implemented by an elastic buckle. The limiting buckle 111 is preferably provided on both sides of the groove wall of the first receiving groove 11. When the support leg 4 is stored in the first receiving groove 11, the limiting buckle 111 undergoes elastic deformation to abut against the side wall of the support leg 4, thereby preventing the support leg 4 from coming out of the first receiving groove 11.

[0042] Reference Figure 2 and Figure 7 The lower end of the support leg 4 is provided with a support foot 44, which is an extension structure installed at the bottom of the support leg 4. The width of the support foot 44 is greater than the width of the support leg 4 to increase the contact area between the support leg 4 and the car floor mat, thereby improving the stability of the support. Furthermore, a positioning key 5 is inserted through the support foot 44 as a transmission component. The bottom end of the positioning key 5 protrudes away from the support foot 44, and the other end of the positioning key 5 abuts against an indicator plate 51. The protruding design of the positioning key 5 causes it to push against the indicator plate 51 when its bottom end contacts the car floor mat. The indicator plate 51 is an identification element located inside the support foot 44, and can use a slider or baffle with bright color contrast to indicate the installation status of the support foot 44. The support foot 44 is also provided with a viewing window 441 for observing changes in the indicator plate 51 from the outside. When the support leg 44 contacts the car floor mat and bears pressure, the bottom end of the positioning key 5 is subjected to an upward reaction force, forcing the positioning key 5 to move upward. The other end of the positioning key 5 pushes the indicator plate 51 to rise simultaneously. When the indicator plate 51 is lifted into the visible range of the viewing window 441, the visible markings on the indicator plate 51 can be observed through the viewing window 441, thus confirming that the support leg 4 is installed in place. Conversely, if the support leg 44 does not contact the car floor mat, the bottom end of the positioning key 5 is not pressed, and the indicator plate 51 remains in its initial position. At this time, there are no visible markings in the viewing window 441, indicating that the position of the support leg 4 needs to be readjusted.

[0043] Reference Figure 1 and Figure 2 The bottom of the support base 1 is provided with a second receiving groove 14 for the support foot 44 to be received. The second receiving groove 14 matches the outer contour of the support foot 44 and is connected to the first receiving groove 11. When the support foot 44 is received in the second receiving groove 14, the support foot 44 abuts against the groove wall of the second receiving groove 14. On the one hand, the friction between the support foot 44 and the groove wall of the second receiving groove 14 restricts the support foot 44 from coming out of the second receiving groove 14. On the other hand, since the width of the support foot 44 is greater than the width of the support leg 4, the width of the second receiving groove 14 is correspondingly greater than the width of the first receiving groove 11. The support foot 44 abutting against the groove wall of the second receiving groove 14 on the side facing the first receiving groove 11 can restrict the support leg 4 from sliding along the length direction of the first receiving groove 11, thereby further improving the stability of the support leg 4 when it is received.

[0044] Reference Figure 8 One side of the support base 1 extends upward to form a support part 6. Specifically, the support part 6 is molded simultaneously with the support base 1 through injection molding, so that the support part 6 and the support base 1 form an integral continuous structure. The height extension direction of the support part 6 forms a vertical support relationship with the bearing plane of the support base 1. When the safety seat is installed, the backrest of the safety seat body contacts the front wall of the support part 6. The support part 6 provides support for the backrest of the safety seat body, reducing the shaking phenomenon caused by the lack of support of the backrest.

[0045] The implementation principle of a safety seat base according to an embodiment of this application is as follows: When the support leg 4 is unfolded, the support leg 4 is rotated so that the support foot 44 rotates out from the second receiving groove 14 and the support leg 4 rotates out from the first receiving groove 11 to the installation position perpendicular to the support base 1. Then, the sliding member 32 is pulled, and the telescopic tube 31 extends until the stop part 314 contacts the end face of the fixed leg 41. The elastic ejector 312 pops out to indicate that the sliding member 32 has slid into place. Pressing the pressing part 433 causes the insertion part 431 to disengage from the gear hole 421. The telescopic leg 42 is adjusted so that the bottom of the support foot 44 abuts against the car floor mat. The bottom end of the positioning key 5 abuts against the car floor mat, forcing the indicator plate 51 to rise. The visible marking on the indicator plate 51 is observed through the viewing window 441 to indicate that the support leg 4 is adjusted into place. After adjusting the telescopic leg 42 to the appropriate position, the pressing part 433 is released so that the insertion part 431 is inserted into the designated gear hole 421 to complete the fixing of the support leg 4. When retracting the support leg 4, press the elastic ejector 312 to retract the elastic ejector 312 into the fixed leg 41, push the sliding member 32 back into the sliding groove 12, adjust the support leg 4 to the retracted length by adjusting the pin 43, then rotate the support leg 4 to retract into the first receiving groove 11, and the support foot 44 to retract into the second receiving groove 14. The limiting buckle 111 prevents the support leg 4 from coming out of the first receiving groove 11.

[0046] This application also discloses a child safety seat, as shown in the embodiments. Figure 8 The child safety seat includes the seat body 7 and the safety seat base as described above.

[0047] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
