Description

Technical Field

[0001] The invention relates to the technical field of ISOFIX, and in particular to a multifunctional adapter for connecting a child safety seat with a car seat. Background Art

[0002] The Child Safety Seat Anchor System (ISOFIX for short) is a new standard for placing child safety seats in cars. The child safety seat is connected to the ISOFIX connection part set in the back seat of the car through the ISOFIX connection device. Existing ISOFIX connection devices are generally fixedly set on the base of the child safety seat for safety reasons. When the ISOFIX connection device fails or is damaged, it is difficult and time-consuming to remove. In addition, when installing and removing the existing ISOFIX connection device from the back seat of the car, both hands are needed to unlock the connectors on the left and right sides at the same time, which is cumbersome to operate and the user experience is not good. Summary of the invention

[0003] The object of the present invention is to provide a multifunctional adapter which can be connected to or detached from a child safety seat and a car seat, has simple connection, and is simple and convenient to operate.

[0004] In order to achieve the above-mentioned purpose, the multifunctional adapter provided by the present invention includes a first connecting device, a second connecting device, a driving shaft and a gear, the first connecting device is connected to the driving shaft, the second connecting device is pivotally connected to the driving shaft, the first connecting device includes a first seat body, a first locking piece, a first driving assembly and a rack, the first locking piece is pivotally connected to the first seat body, the first driving assembly is arranged on the first seat body, the rack is arranged at one end of the first driving assembly, and the gear is meshed with the rack; the driving shaft is coaxially fixedly connected to the gear to drive the rack to move through the gear, so that the first driving assembly drives the first locking piece to rotate to a released state.

[0005] Compared with the prior art, the present invention provides a first connection device and a second connection device on the drive shaft, respectively, and uses the first connection device to connect the child safety seat, and uses the second connection device to connect the car seat, so that the multifunctional adapter can be quickly connected or disassembled with the child safety seat and the car seat, and the connection is simple. In addition, the first connection device includes a first seat body, a first locking member, a first driving assembly and a rack, so that the rack is meshed with the gear, and the gear is connected to the drive shaft. Therefore, by driving the drive shaft, the drive shaft drives the gear to rotate, and then the gear can drive the first locking member through the first driving assembly to release the connection shaft 200 of the child safety seat. Therefore, even if multiple first connection devices are provided on the drive shaft, the present solution only needs to operate the drive shaft with one hand when releasing the lock, and compared with the traditional structure, its operation is simpler and more convenient.

[0006] Preferably, the first driving assembly includes a first slider and a first elastic member, the first slider is slidably disposed on the first seat body and one end is connected to the rack, and the other end abuts against the first locking member, and the first elastic member is connected between the eccentric position of the first locking member and the first slider. By using the first slider to abut the first locking member, the first locking member cannot be rotated and is locked in the locked position, thereby ensuring the firmness and stability of the locking, and the first elastic member is connected between the eccentric position of the first locking member and the first slider, so that when the first slider slides away from the first locking member, the elastic force of the first elastic member can be used to pull the first locking member to rotate, thereby rotating the first locking member to the unlocking position. In this way, the first connecting device can be switched between the locked and unlocked states to achieve connection or separation with the child safety seat.

[0007] Preferably, a first bayonet is provided on one side of the first locking member, and the first locking member is in a released state when it is rotated so that the first bayonet is facing the same direction as the moving direction of the first slider; and is in a locked state when the first locking member is rotated so that the first bayonet is facing and intersects with the moving direction of the first slider.

[0008] Preferably, a step is provided in a concave manner on one side of the first locking member near the first slider, and a curved surface is provided on the other side adjacent thereto. A clamping portion is provided at one end of the first driving assembly near the first locking member to engage with the step. When the clamping portion engages with the step, the first locking member is in a locked state. When the clamping portion abuts against the curved surface, the first locking member is in a released state. By utilizing the step and the clamping portion, the first slider and the first locking member can be more stably engaged, thereby making the first connection device more firmly connected. Furthermore, by providing a curved surface on the other side of the first locking member, the curved surface abuts against the clamping portion, so that when the first locking member abuts against the connecting shaft 200 of the child safety seat, the abutting force of the connecting shaft 200 and the curved surface can be used to push the first locking member to rotate, thereby rotating the first locking member to a locked state, without the need for manual locking, thereby improving the convenience of connection and operation.

[0009] Preferably, the driving shaft is a square shaft. Setting the cross section of the driving shaft to be square can make it more firmly connected with the gear, effectively preventing the two from slipping, thereby improving the reliability of the work.

[0010] Preferably, the multifunctional adapter further comprises a first operating member, which is fixedly disposed on the driving shaft, and can rotate and drive the driving shaft to rotate. The driving shaft can be operated by the first operating member, so that the driving shaft can be rotated more easily, and only one hand is needed to twist the first operating member to rotate the entire driving shaft, thereby releasing multiple first connecting devices at the same time, effectively improving the convenience of operation.

[0011] Preferably, the second connecting device includes a second base body, a second locking member, a second slider, a second elastic member and a second operating member, the second locking member is pivotally connected to the second base body, the second slider is slidably disposed on the second base body and has one end connected to the second operating member and the other end abutting against the second locking member, the second elastic member is connected between an eccentric position of the second locking member and the second slider; by pulling the second operating member, the second slider drives the second locking member to rotate to a released state.

[0012] Specifically, a second bayonet is provided on one side of the second locking member, and the second locking member is in a released state when it is rotated so that the second bayonet is in the same direction as the moving direction of the second slider; and the second locking member is in a locked state when it is rotated so that the second engagement direction intersects with the moving direction of the second slider.

[0013] Specifically, a step is recessed on one side of the second locking member close to the second slider, and an arc surface is provided on the other adjacent side. An engaging portion that engages with the step is provided on one end of the second slider close to the second locking member. When the engaging portion engages with the step, the second locking member is in a locked state; when the engaging portion abuts against the arc surface, the second locking member is in a released state.

[0014] Specifically, the number of the second connection devices is two, which are symmetrically arranged at the two ends of the driving shaft; the number of the first connection devices is two, and they are arranged between the two second connection devices. In this way, there are two connection points between the child safety seat and the car seat, so that the connection between the two is more firm and stable.

[0022] In order to explain the technical content, structural features and achieved effects of the present invention in detail, the following is a detailed description in conjunction with the implementation methods and the accompanying drawings.

[0023] like Figure 1 and Figure 2As shown, the present invention discloses a multifunctional adapter 100, which is suitable for connecting a child safety seat to a rear seat of a car. The multifunctional adapter 100 includes a first connecting device 1, a second connecting device 2, a drive shaft 3 and a gear 4. The first connecting device 1 is connected to the drive shaft 3, the second connecting device 2 is pivoted to the drive shaft 3, and the number of the second connecting devices 2 is two, which are symmetrically arranged at both ends of the drive shaft 3; the number of the first connecting device 1 is two, and they are arranged between the two second connecting devices 2. In this way, there are two connection points between the child safety seat and the car seat, so that the connection between the two is more firm and stable. The extension direction of the first connecting device 1 is opposite to the extension direction of the second connecting device 2. The first connecting device 1 includes a first seat body 11, a first locking member 12, a first driving assembly 13 and a rack 14. The first locking member 12 is pivoted to the first seat body 11 through a pivot shaft 12a, the first driving assembly 13 is arranged on the first seat body 11, and the rack 14 is arranged at one end of the first driving assembly 13. The number of the gears 4 is the same as the number of the first connecting device 1, and the gears 4 are meshed with the racks 14; the drive shaft 3 is coaxially fixedly connected to the gears 4, so that the racks 14 are driven to move by the gears 4, so that the first drive assembly 13 drives the first locking member 12 to rotate to a released state. The drive shaft 3 is a square shaft. An outer tube 31 is sleeved on the outer side of the drive shaft 3, and the drive shaft 3 is rotatable relative to the outer tube 31, and the outer tube 31 can protect the drive shaft 3. The cross section of the drive shaft 3 is set to be square, so that it can be more firmly connected to the gear 4, effectively preventing the two from slipping, thereby ensuring the reliability of the work.

[0024] Combination Figure 2 and Figure 3Specifically, the first driving assembly 13 includes a first slider 131 and a first elastic member 132. The first slider 131 is slidably disposed on the first seat 11 and one end of the slider 131 is connected to the rack 14, and the other end of the slider 131 abuts against the first locking member 12. The sliding direction of the first slider 131 is along the length extension direction of the first connecting device 1. An elongated hole 131a is disposed in the middle of the first slider 131. A central axis 11a is fixedly disposed in the first seat 11. The central axis 11a passes through the elongated hole 131a and can slide in the elongated hole 131a to guide and limit the first slider 131. The rack 14 is disposed in the same direction as the sliding direction of the first slider 131. The first locking member 12 has an eccentric position outside the pivot axis 12a. The first slider 131 extends a connecting portion. The first elastic member 132 is connected between the eccentric position of the first locking member 12 and the connecting portion 131c of the first slider 131. The first elastic member 132 is a tension spring. By using the first slider 131 to push against the first lock member 12, the first lock member 12 can be locked in the locked position without being rotated, thereby ensuring the firmness and stability of the locking. The first elastic member 132 is connected between the eccentric position of the first lock member 12 and the first slider 131, so that when the first slider 131 slides away from the first lock member 12, the elastic force of the first elastic member 132 can be used to pull the first lock member 12 to rotate, so that the first lock member 12 rotates to the unlocking position. In this way, the first connecting device 1 can be switched between the locked and unlocked states to achieve connection or separation with the child safety seat. A first bayonet 121 is provided on one side of the first lock member 12, and an opening 11b is provided at the front end of the first seat body 11. When the first lock member 12 is rotated to make the first bayonet 121 face the same direction as the moving direction of the first slider 131, the first bayonet 121 faces the same direction as the opening 11b, and the first lock member 12 is in the unlocking state / unlocking position. When the first locking member 12 is rotated to make the first bayonet 121 intersect / be perpendicular to the moving direction of the first slider 131 , the first bayonet 121 intersects / be perpendicular to the opening 11 b , and the first locking member 12 is in a locked state / locked position.

[0025] Please see again Figure 2 and Figure 3The first locking member 12 has a step 122 recessed on one side close to the first slider 131, and an arc surface 123 on the other side adjacent thereto. The first slider 131 has a clamping portion 131b clamped with the step 122 on one end close to the first locking member 12. When the clamping portion 131b is clamped with the step 122, the first locking member 12 is in a locked state. When the clamping portion 131b abuts against the arc surface 123, the first locking member 12 is in a released state. By utilizing the step 122 and the clamping portion 131b, the first slider 131 and the first locking member 12 can be clamped more stably, thereby making the first connection device 1 more firmly connected. Furthermore, by providing an arc surface 123 on the other side of the first locking member 12, the arc surface 123 is used to abut against the engaging portion 131b. Thus, when the first locking member 12 abuts against the connecting shaft 200 of the child safety seat, the abutting force of the connecting shaft 200 and the arc surface 123 can be used to push the first locking member 12 to rotate, thereby rotating the first locking member 12 to a locked state without manual locking, thereby improving the convenience of connection and operation.

[0026] Please see again Figure 1 and Figure 2 The multifunctional adapter 100 further includes a first operating member 5, which is fixedly disposed at at least one end of the drive shaft 3. The first operating member 5 is a knob and is coaxially disposed with the drive shaft 3. In this solution, the first operating member 5 is fixed at both ends of the drive shaft. Of course, it can also be disposed at one end of the first operating member 5. The first operating member 5 can rotate and drive the drive shaft 3 to rotate. By operating the drive shaft 3 with the first operating member, the drive shaft 3 can be rotated more easily, and only one hand is needed to twist the first operating member 5 to rotate the entire drive shaft 3, thereby simultaneously releasing multiple first connection devices 1, effectively improving the convenience of operation.

[0027] See also Figure 2 and Figure 4The second connecting device 2 comprises a second seat 21, a second locking member 22, a second slider 23, a second elastic member 24 and a second operating member 25. The second locking member 22 is pivotally connected to the second seat 21. The second slider 23 is slidably disposed on the second seat 21 and fixedly connected to the second operating member 25 at one end and abutted against the second locking member 22 at the other end. The sliding direction of the second slider 23 is along the length extension direction of the second connecting device 2. An elongated hole 23a is disposed in the middle of the second slider 23. A central axis 21a is fixedly disposed in the second seat 21. The central axis 21a passes through the elongated hole 23a and can slide in the elongated hole 23a to guide and limit the second slider 23. The second elastic member 24 is connected between the eccentric position of the second locking member 22 and the connecting portion 231 of the second slider 23. The second elastic member 24 is a tension spring. The second operating member 25 is located outside the second seat 21. By pulling the second operating member 25, the second slider 23 drives the second locking member 22 to rotate to the unlocked state. A second bayonet 221 is provided on one side of the second locking member 22, and an opening 21b is provided at the front end of the second seat 21. When the second locking member 22 is rotated to make the second bayonet 221 face the same direction as the moving direction of the second slider 23, the direction of the second bayonet 221 is the same direction as the opening 21b, and the second locking member 22 is in the unlocked state / unlocked position. When the second locking member 22 is rotated to make the second bayonet 221 face the moving direction of the second slider 23, the direction of the second bayonet 221 faces the opening 21b, and the second locking member 22 is in the locked state / locked position.

[0028] Please see again Figure 2 and Figure 4The second locking member 22 has a step 222 recessed on one side close to the second slider 23, and an arc surface 223 on the other side. The second slider 23 has a locking portion 23b engaged with the step 222 on one end close to the second locking member 22. When the locking portion 23b is engaged with the step 222, the second locking member 22 is in a locked state. When the locking portion 23b abuts against the arc surface 223, the second locking member 22 is in a released state. By using the step 222 and the locking portion 23b, the second slider 23 and the second locking member 22 can be engaged more stably, so that the second connection device 2 is more firmly connected. Furthermore, by providing an arc surface 223 on the other side of the second locking member 22, the arc surface 223 is used to abut against the engaging portion 23b. Thus, when the second locking member 22 abuts against the connecting shaft 200 of the child safety seat, the abutting force of the connecting shaft 200 and the arc surface 223 can be used to push the second locking member 22 to rotate, thereby rotating the second locking member 22 to a locked state without manual locking, thereby improving the convenience of connection and operation.

[0029] Combining the above and Figures 3 to 6 The working principle of the multi-function adapter 100 of the present invention is described in detail below:

[0030] When the multifunctional adapter 100 is not connected, the first bayonet 121 of the first locking member 12 of the first connecting device 1 is in the same direction as the opening 11b of the first seat body 11, and the second bayonet 221 of the second locking member 22 of the second connecting device 2 is in the same direction as the opening 21b of the second seat body 21. When the child safety seat needs to be connected to the car seat, the second connecting device 2 is first inserted into the ISOFIX interface of the car seat. At this time, the connecting shaft 300 in the ISOFIX interface of the car seat enters the second bayonet 221 of the second locking member 22 and presses against the second locking member 22, so that the second locking member 22 rotates. After the second locking member 22 rotates 90 degrees, it is perpendicular to the opening 21b of the second seat body 21. At this time, the second locking member 22 and the second seat body 21 jointly lock the connecting shaft 300. The second connecting device 2 can be connected to the car seat. Similarly, after placing the child safety seat on the car seat, connect the ISOFIX interface of the child safety seat to the first connecting device 1; so that the connecting shaft 200 in the ISOFIX interface of the child safety seat enters the first bayonet 121 of the first locking member 12 and abuts against the first locking member 12, so that the first locking member 12 rotates, and after the first locking member 12 rotates 90 degrees, it is perpendicular to the opening 11b of the first seat body 11. At this time, the first locking member 12 and the first seat body 11 jointly lock the connecting shaft 200. The first connecting device 1 can be connected to the child safety seat. At this time, the child safety seat can be fixed on the car seat.

[0031] When the child safety seat needs to be detached from the car seat, only one hand is needed to twist the first operating member 5, and the first operating member 5 rotates to drive the driving shaft 3 to rotate, and the driving shaft 3 rotates to drive the two gears 4 to rotate, and the two gears 4 rotate to drive the racks 14 on the first connecting device 1 to move, and the racks 14 move to drive the first slider 131 to move, and the first slider 131 moves to make the engaging portion 131b leave the step 122 of the first locking member 12, and the first slider 131 stretches the first elastic member 132. When the engaging portion 131b completely leaves the step 122, under the elastic force of the first elastic member 132, the first locking member 12 rotates around the pivot axis 12a, so that the arc surface 123 approaches the engaging portion 131b, and the first bayonet 121 rotates to the same direction as the opening 11b of the first seat body 11. At this time, the first locking members 12 of the two first connecting devices 1 can release the connecting shaft 200 in the ISOFIX interface of the child safety seat to achieve unlocking. Similarly, when the multifunctional adapter 100 needs to be detached from the car seat, it is only necessary to pull the second operating member 25, thereby driving the second slider 23 to slide, so that the second locking member 22 and the connecting shaft 300 in the ISOFIX interface of the car seat are released, and the multifunctional adapter 100 can be removed from the car seat.

[0032] Compared with the prior art, the present invention provides the first connecting device 1 and the second connecting device 2 on the driving shaft 3, respectively, and uses the first connecting device 1 to connect the child safety seat, and uses the second connecting device 2 to connect the car seat, so that the multifunctional adapter 100 can be quickly connected or disassembled with the child safety seat and the car seat, and the connection is simple. In addition, the first connecting device 1 includes a first seat body 11, a first locking member 12, a first driving assembly 13 and a rack 14, so that the rack 14 is meshed with the gear 4, and the gear 4 is connected to the driving shaft 3. Therefore, by driving the driving shaft 3, the driving shaft 3 drives the gear 4 to rotate, and then the gear 4 can drive the first locking member 12 through the first driving assembly 13 to release the connecting shaft 200 of the child safety seat. Therefore, even if multiple first connecting devices 1 are provided on the driving shaft 3, the present solution only needs to operate the driving shaft 3 with one hand when releasing the lock, and compared with the traditional structure, its operation is simpler and more convenient.

[0033] The ISOFIX interface structures of the child safety seat and the car seat involved in the multifunctional adapter 100 of the present invention are well known to those skilled in the art and will not be described in detail herein.

[0034] The above disclosure is only a preferred embodiment of the present invention, and certainly cannot be used to limit the scope of rights of the present invention. Therefore, equivalent changes made according to the scope of the patent application of the present invention still fall within the scope covered by the present invention.
