[0001] This invention relates to the field of child car seat technology, and in particular to a child safety seat. Background Technology

[0002] In related technologies, car seats often achieve their rotating function by using a rotating mechanism to drive the seat body to rotate. However, the rotating mechanism in existing car seats is easily misoperated by users, causing the car seat to rotate when it should not, posing a certain safety risk and affecting the safety of children riding in it. Summary of the Invention

[0003] The present invention aims to at least solve one of the technical problems existing in the prior art. To this end, the present invention proposes a child safety seat that can improve the safety of children while riding.

[0004] According to a first aspect of the present invention, a safety seat is provided, comprising a base, a rotating seat, a seat body, a locking assembly, and a locking component. The base is provided with a mounting platform. The rotating seat is disposed on the base and is rotatable relative to the base. The outer peripheral wall of the rotating seat is provided with a circumferentially extending limiting groove. The lower end face of the rotating seat is provided with a plurality of locking holes, which are spaced apart circumferentially. The seat body includes a backrest and a headrest connected to each other, and the backrest is mounted on the rotating seat. The locking assembly includes a first lever, a transmission member, a first elastic member, and a first locking member. The first lever is rotatably connected to the base. The first locking member is disposed on the mounting platform and is slidable toward or away from the rotating seat. The first elastic member is disposed on the mounting platform. Inside, the first elastic element is used to push the first locking element and insert the first locking element into the locking hole. The first lever is connected to the first locking element through the transmission element. The first lever can rotate and drive the first locking element to separate from the locking hole. The locking assembly includes a sliding seat, a second lever, and a limiting rod. The sliding seat is installed on the base. The sliding seat is provided with a guide rail extending along the length direction of the sliding seat. The second lever is slidably connected to the guide rail to move along the length direction of the sliding seat. The limiting rod is provided on the base and can move toward or away from the rotating seat. The second lever is connected to the limiting rod. The second lever can slide and drive the limiting rod into or out of the limiting groove.

[0005] A child safety seat according to an embodiment of the present invention has at least the following beneficial effects:

[0006] This invention applies a rotary locking mechanism to a child safety seat. When rotation is not required, the first locking member remains inserted into the locking hole at the bottom of the rotating seat under the action of the first elastic member, thus locking the rotating seat. When rotation is required, the first lever can be rotated, which drives the transmission member to move, thereby moving the first locking member to separate it from the locking hole, unlocking the rotating seat. The user can then rotate the rotating seat as needed. When the rotating seat rotates to a certain angle, the other locking hole aligns with the first locking member. Under the push of the first elastic member, the first locking member automatically inserts into the locking hole, completing the locking after rotation. The rotary locking mechanism provided in the first aspect of this invention has a simple structure, high reliability, and only requires rotating the first lever to unlock, making operation simple and convenient. Furthermore, by incorporating a reversing locking component into the reversing mechanism, when a smaller child needs to ride in the reverse direction, the second lever will actuate the limiting rod to insert it into the limiting groove of the rotating seat. Under the constraint of the limiting rod and the limiting groove, the rotating seat can rotate within the arc range of the limiting groove without turning to the forward-facing side. This helps prevent users from accidentally turning the seat and causing the child to ride in the forward direction, thus reducing the risks associated with children riding in the forward direction.

[0007] According to some embodiments of the present invention, the first paddle block is provided with an arc-shaped groove on the side facing the transmission member, and the transmission member is provided with a column at one end near the first paddle block, the column being inserted into the arc-shaped groove.

[0054] In related technologies, car seats often achieve their rotating function by using a rotating mechanism to drive the seat body to rotate. However, the rotating mechanism in existing car seats is easily misoperated by users, causing the car seat to rotate when it should not, posing a certain safety risk and affecting the safety of children riding in it.

[0055] Therefore, some embodiments of the present invention provide a safety seat 1000, as detailed in the accompanying drawings. Figures 1-16 As shown.

[0056] Reference Figure 1 and Figure 2 As shown, in this embodiment of the invention, the child safety seat 1000 may include a base 100, a rotating seat 200, a seat body 300, a locking assembly 400, and a locking assembly 500. (Refer to...) Figure 3 and Figure 5 As shown, the base 100 is provided with a mounting platform 110; the rotating seat 200 is disposed on the base 100 and can rotate relative to the base 100. The outer peripheral wall of the rotating seat 200 is provided with a limiting groove 210 extending circumferentially, and the lower end face of the rotating seat 200 is provided with a plurality of locking holes 220, which are spaced apart circumferentially. (Refer to...) Figure 1 and Figure 2 As shown, the seat body 300 includes a backrest 310 and a headrest 320 that are connected to each other. Specifically, the backrest 310 and the headrest 320 can be slidably connected. The backrest 310 is mounted on the rotating seat 200, so that the seat body 300 can rotate with the rotating seat 200.

[0057] Reference Figure 3 , Figure 4 and Figure 5 As shown, in this embodiment of the invention, the locking assembly 400 includes a first lever 410, a transmission member 420, a first elastic member 430, and a first locking member 440. The first lever 410 is rotatably connected to the base 100. The first locking member 440 is disposed on the mounting platform 110 and can slide toward or away from the rotating seat 200. The first elastic member 430 is disposed in the mounting platform 110 and is used to push the first locking member 440 and insert the first locking member 440 into the locking hole 220. The first lever 410 is connected to the first locking member 440 through the transmission member 420. The first lever 410 can rotate and drive the first locking member 440 to separate from the locking hole 220.

[0058] Reference Figure 5 , Figure 6 and Figure 7 As shown, in this embodiment of the invention, the locking component 500 includes a sliding seat 510, a second lever 520, and a limiting rod 530. The sliding seat 510 is mounted on the base 100, and the second lever 520 is slidably connected to the sliding seat 510. Specifically, the sliding seat 510 is provided with a guide rail 511 extending along the length direction of the sliding seat 510. The second lever 520 is slidably connected to the guide rail 511 to move along the length direction of the sliding seat 510, thereby improving the accuracy of the movement direction of the second lever 520 and facilitating the user to move the second lever 520. The limiting rod 530 is located on the base 100 and can move toward or away from the rotating seat 200. The second lever 520 is connected to the limiting rod 530, and the second lever 520 can slide and drive the limiting rod 530 into or out of the limiting groove 210.

[0059] This invention applies a rotary locking mechanism to a child safety seat 1000. When rotation is not required, the first locking member 440 remains inserted into the locking hole 220 at the bottom of the rotating seat 200 under the action of the first elastic member 430, thus locking the rotating seat 200. When rotation is required, the first lever 410 can be rotated, which drives the transmission member 420 to move, thereby moving the first locking member 440 to separate it from the locking hole 220, unlocking the rotating seat 200. The user can then rotate the rotating seat 200 as needed. When the rotating seat 200 rotates to a certain angle, the other locking hole 220 aligns with the first locking member 440. Under the push of the first elastic member 430, the first locking member 440 automatically inserts into the locking hole 220, completing the locking after rotation. The rotary locking mechanism provided in the first aspect of this invention has a simple structure, high reliability, and only requires rotating the first lever 410 to unlock, making operation simple and convenient. Furthermore, by incorporating a reversing locking component 500 in the reversing mechanism, when a smaller child needs to ride in the reverse direction, the second lever 520 actuates the limiting rod 530 so that the limiting rod 530 is inserted into the limiting groove 210 of the rotating seat 200. Under the constraint of the limiting rod 530 and the limiting groove 210, the rotating seat 200 can rotate within the arc range of the limiting groove 210, while the rotating seat 200 will not rotate to the side facing forward. This helps prevent the user from accidentally rotating the seat and causing the child to ride in the forward direction, thus reducing the risks caused by the child riding in the forward direction.

[0060] Reference Figure 3 and Figure 4 As shown, in this embodiment of the invention, the first lever 410 has an arc-shaped plate on the side facing the transmission member 420, and an arc-shaped groove 411 is provided on the arc-shaped plate. A column 421 is provided at the end of the transmission member 420 near the first lever 410, and the column 421 is inserted into the arc-shaped groove 411. When the first lever 410 is rotated, the arc-shaped plate of the first lever 410 drives the column 421 inserted into the arc-shaped groove 411 to move, thereby driving the transmission member 420 to move. The structure of the first lever 410 and the transmission member 420 is simple, and the transmission method is stable and reliable. It should be noted that a tension spring for pulling the first lever 410 back to its original position can be provided between the first lever 410 and the base 100. It should be noted that when unlocking is required, the first lever 410 is rotated. The arc-shaped plate on the side of the first lever 410 near the transmission component 420 drives the column 421 inserted in the arc-shaped groove 411 to move. The movement of the column 421 drives the first locking component 440 to move, so that the first locking component 440 is separated from the locking hole 220 on the rotating seat 200, thus completing the unlocking of the rotating seat 200.

[0061] Reference Figure 3 and Figure 4As shown, in this embodiment of the invention, two guide plates 422 are spaced apart at one end of the transmission member 420 near the first locking member 440, forming an installation position between the two guide plates 422. Each guide plate 422 is provided with an inclined guide groove 4221. The first locking member 440 includes a square post and guide posts 441. Guide posts 441 are provided on opposite sides of the square post. Each guide post 441 on the square post is inserted into the guide groove 4221 on a guide plate 422. When the first lever 410 drives the transmission member 420 to move, the inclined wall of the guide groove 4221 on the guide plate 422 presses against the guide post 441, so that the guide post 441 slides along the guide groove 4221 to separate the first locking member 440 from the locking hole 220. The transmission method from the transmission member 420 to the first locking member 440 is stable and reliable. It should be noted that when unlocking, rotating the first lever 410 can drive the transmission component 420 to move. The inclined wall of the guide groove 4221 on the guide plate 422 presses against the guide post 441 so that the guide post 441 slides along the guide groove 4221, thereby separating the first locking component 440 from the locking hole 220, thus unlocking the rotating seat 200.

[0062] Reference Figure 5 , Figure 6 and Figure 7 As shown, in this embodiment of the invention, the base 100 is provided with a mounting post 120, and the limiting rod 530 is provided with a first through groove 531 arranged along the length direction. During installation, the first through groove 531 on the limiting rod 530 is aligned with the mounting post 120, and the mounting post 120 is inserted into the first through groove 531. When the second lever 520 is turned, the mounting post 120 on the base 100 can play a guiding role and limit the movement trajectory of the limiting rod 530. During the process of the limiting rod 530 entering or leaving the limiting groove 210 on the outer wall of the rotating seat 200, the movement trajectory of the limiting rod 530 is not easily deviated. It should be noted that the limiting groove 210 extends along the outer periphery of the rotating seat 200, and it can extend to 90 degrees, 10 degrees, or 15 degrees. A tension spring can also be provided between the base 100 and the second lever 520 to increase the tension of the reversing locking assembly 500.

[0063] Reference Figure 5 , Figure 6 and Figure 7As shown, in this embodiment of the invention, the limiting rod 530 is further provided with a first receiving groove 532 communicating with the first through groove 531. The first receiving groove 532 is arranged along the length direction of the limiting rod 530. A second elastic member 540 is provided in the first receiving groove 532. One end of the second elastic member 540 abuts against the wall surface of the first receiving groove 532 away from the mounting post 120, and the other end abuts against the mounting post 120. By providing the second elastic member 540 between the mounting post 120 and the limiting rod 530, when the second lever 520 is moved, the elastic force provided by the second elastic member 540 can improve the tension of the entire reversing locking assembly 500, so that the limiting rod 530 can enter the limiting groove 210 more stably. By providing the first receiving groove 532 on the limiting rod 530 to accommodate the second elastic member 540, it is beneficial to improve the compactness of the structure of the entire reversing locking assembly 500.

[0064] Because users often rely solely on feel and experience to adjust the height of the support legs, it's difficult to determine whether the legs are fully in contact with the floor, making it hard to confirm proper installation. Therefore, referring to... Figure 2 , Figure 8 and Figure 9 As shown, in this embodiment of the invention, the support mechanism 600 may include: an outer tube 610, an inner tube 620, a display component 630, and a fixing component 640. The outer tube 610 may have a cavity 611 extending vertically inside, the size and shape of which match the inner tube 620. The outer tube 610 has a second through groove 612 communicating with the cavity 611 on its exterior. It should be noted that the end of the support mechanism 600 facing the vehicle floor is the lower end, and the end away from the vehicle floor is the upper end. The extending direction of the inner tube 620 may be consistent with the extending direction of the cavity 611. Therefore, the inner tube 620 can pass through the cavity 611 and slide in connection with the outer tube 610. The relative sliding between the inner tube 620 and the outer tube 610 enables the height of the support mechanism 600 to be adjustable. The inner tube 620 may have multiple locking holes 621, which are spaced apart vertically. Specifically, refer to... Figure 9 and Figure 11 As shown, the second through groove 612 can be connected to any of the slots 621. It should be noted that the length of the second through groove 612 in the vertical direction is greater than the length of the slot 621 in the vertical direction.

[0065] Reference Figure 8 , Figure 9 and Figure 10As shown, in this embodiment of the invention, the display component 630 can be installed on the outer tube 610. Specifically, the display component 630 can be detachably connected to the outer tube 610, or it can be slidably connected, allowing the display component 630 to move up and down along the outer tube 610. This embodiment does not limit this. The display component 630 may include an identifier 632 and a driving component 633 connected to each other. It should be noted that the identifier 632 and the driving component 633 can be directly connected, or they can be indirectly connected through other components. This embodiment does not limit this. The identifier 632 may have a first identifier 6321 and a second identifier 6322. The identifier 632 showing the first identifier 6321 can indicate that the inner tube 620 is in a non-supported state, and the identifier 632 showing the second identifier 6322 can indicate that the inner tube 620 is in a supported state. The first identifier 6321 and the second identifier 6322 can be visual identifiers. For example, the first identifier 6321 can be a red sticker, and the second identifier 6322 can be a green sticker. The first identifier 6321 and the second identifier 6322 can also be other types of visual identifiers. Those skilled in the art can choose to set them according to the actual situation, and this embodiment does not limit them. The driving component 633 can move up and down to drive the identifier component 632 to rotate. When the identifier component 632 rotates, the positions of the first identifier 6321 and the second identifier 6322 can be switched, thereby displaying the first identifier 6321 or the second identifier 6322.

[0066] Reference Figure 9 and Figure 11 As shown, in this embodiment of the invention, the fixing component 640 may include a second locking member 641 and a connecting member 642. It is understood that when the inner tube 620 can slide relative to the outer tube 610, the inner tube 620 is in an active state; when the inner tube 620 cannot slide relative to the outer tube 610, the inner tube 620 is in a locked state. Specifically, when the inner tube 620 is in the locked state, the second locking member 641 can pass through the second through groove 612 and engage with one of the locking holes 621, thereby fixing the relative position of the inner tube 620 and the outer tube 610. When the inner tube 620 is in the unlocked state, the second locking member 641 can disengage from the locking hole 621 and the second through groove 612, allowing the inner tube 620 to slide along the inner cavity. One end of the connecting member 642 is connected to the second locking member 641, and the other end is connected to the driving member 633. The inner tube 620 has a supported state and a non-supported state. When the inner tube 620 is in the non-supported state, that is, when the inner tube 620 is not in contact with the vehicle floor or the contact with the vehicle floor is insufficient, the support mechanism 600 is not installed in place, the marking element 632 is in the initial state and displays the first marking 6321. (Refer to...) Figure 10As shown, when the inner tube 620 is in a supported state, the bottom end of the inner tube 620 abuts against the vehicle floor, and the support mechanism 600 is installed in place, the vehicle floor can apply upward pressure to the inner tube 620, thereby driving the inner tube 620 to move upward. At the same time, since the length of the second through groove 612 in the vertical direction is greater than the length of the locking hole 621 in the vertical direction, the inner tube 620 can drive the second locking member 641 to move upward along the second through groove 612 through the locking hole 621. The second locking member 641 is connected to the connecting member 642. Therefore, the second locking member 641 can drive the connecting member 642 to move upward. The connecting member 642 is connected to the driving member 633. The connecting member 642 can drive the driving member 633 to move upward. The upward movement of the driving member 633 can drive the marking member 632 to rotate, so that the marking member 632 can display the second marking 6322.

[0067] Reference Figure 9 , Figure 10 and Figure 11 As shown, in this embodiment of the invention, the outer tube 610 may be provided with two first sliding grooves 613 extending in the vertical direction. The two first sliding grooves 613 are arranged opposite to each other, that is, the two first sliding grooves 613 may be located on both sides of the side wall of the outer tube 610 facing the fixing component 640. The fixing component 640 also includes a pressing member 643 slidably connected to the two first sliding grooves 613. It should be noted that the upper end of the two first sliding grooves 613 is provided with an opening. Therefore, the pressing member 643 can enter the first sliding groove 613 from the upper opening of the first sliding groove 613 and slide along the first sliding groove 613, thereby reducing the installation difficulty of the pressing member 643 and improving the installation efficiency of the pressing member 643. The pressing member 643 is provided with two rotating parts 6431 that correspond one-to-one with the two first sliding grooves 613. The two rotating parts 6431 are respectively provided at both ends of the pressing member 643. The rotating parts 6431 can extend into the corresponding first sliding groove 613 and be rotatably connected to the corresponding first sliding groove 613. At the same time, the rotating parts 6431 can also be slidably connected to the first sliding groove 613, thereby driving the pressing member 643 to slide along the two first sliding grooves 613.

[0068] Reference Figure 9 and Figure 11As shown, in this embodiment of the invention, the pressing member 643 and the second locking member 641 can be fixedly connected. Specifically, the pressing member 643 can include a snap-fit ​​part and a fixing part connected to each other. The snap-fit ​​part can pass through the second through groove 612 and engage with the locking hole 621. The fixing part can pass through the pressing member 643 and be fixedly connected to the pressing member 643. Specifically, the two can be connected by snap-fit, screw, or interference fit. This embodiment does not limit this. The pressing member 643 can drive the second locking member 641 to rotate towards or away from the locking hole 621. Specifically, the pressing member 643 can be provided with a pressing part for the user to press. When the user presses the pressing part, the pressing part can drive the second locking member 641 to rotate around the rotating part 6431 away from the locking hole 621, thereby causing the second locking member 641 to leave the locking hole 621 and the second through groove 612, and causing the inner tube 620 to switch to an active state.

[0069] Reference Figure 9 , Figure 10 and Figure 11 As shown, in this embodiment of the invention, the connector 642 can be inserted into any of the first slide grooves 613. Specifically, the connector 642 can enter the first slide groove 613 from the upper opening of the first slide groove 613. The pressing member 643 and the connector 642 can enter the first slide groove 613 in sequence to complete the installation, which greatly reduces the installation difficulty of the pressing member 643 and the connector 642 and improves the installation efficiency. The driving member 633 may include a connecting part 6331, which can be disposed at the lower part of the driving member 633. The connecting part 6331 can enter the first slide groove 613 from the upper opening of the first slide groove 613, so that the connecting part 6331 and the connector 642 are located in the same first slide groove 613. One end of the connector 642 abuts against the corresponding rotating part 6431, and the other end abuts against the connecting part 6331. It can be understood that the two rotating parts 6431 of the pressing part 643 are respectively located in the two first sliding grooves 613, and the connector 642 can be set in one of the first sliding grooves 613. Therefore, the lower end of the connector 642 can abut against the connecting part 6331 located in the first sliding groove 613, and the upper end of the connector 642 can abut against the connecting part 6331.

[0070] Understandably, since the connector 642 abuts against the rotating part 6431 and the connecting part 6331 respectively, when the inner tube 620 abuts against the vehicle floor, the vehicle floor can apply upward pressure to the inner tube 620, thereby driving the inner tube 620 to move upward. The inner tube 620 can drive the second locking member 641 to move upward along the second through groove 612 through the locking hole 621. The second locking member 641 drives the pressing member 643 to move upward. The pressing member 643 drives the connector 642 to move upward through the connecting part 6331. The connector 642 drives the driving member 633 to move upward through the connecting part 6331. The upward movement of the driving member 633 can drive the marking member 632 to rotate, so that the marking member 632 can display the second marking 6322.

[0071] Reference Figure 8 and Figure 10 As shown, in this embodiment of the invention, the display component 630 may further include a mounting base 631 connected to the outer tube 610. Specifically, the mounting base 631 may be snapped into the outer peripheral wall of the outer tube 610 or connected by screws; this embodiment does not limit this. The mounting base 631 is also provided with a mounting groove suitable for inserting the driving member 633. The mounting groove may be located near the first sliding groove 613 on the mounting base 631, and the mounting groove extends downward to form a space suitable for accommodating the driving member 633 and for the driving member 633 to move. The driving member 633 may be installed in the mounting groove and may move up and down along the mounting groove. The marking member 632 is rotatably connected to the mounting base 631, and the bottom end of the marking member 632 abuts against the top end of the driving member 633. The connecting part 6331 passes through the first sliding groove 613, and the top end of the driving member 633 abuts against the marking member 632 to fix the driving member 633. The connection between the first sliding groove 613 and the connecting part 6331 may also guide the movement of the driving member 633.

[0072] Reference Figure 1 , Figure 2 and Figure 14 As shown, in this embodiment of the invention, the adjustment mechanism may include: a chair back 310, a moving component 700, and a pull strap 730. The chair back 310 may have multiple fixing grooves 311, which are spaced apart along a first direction, i.e., the arrangement direction of the fixing grooves 311, which is also the moving direction of the headrest 320. The fixing grooves 311 may be located at the front end of the chair back 310 and may be recessed rearward.

[0073] Reference Figure 2 , Figure 12 and Figure 14As shown, in this embodiment of the invention, the movable component 700 may include a headrest 320, a locking pin 710, and a rotating base 720. The locking pin 710 is mounted on the rotating base 720 and can engage with one of the fixing slots 311. It is understood that the movable component 700 can have a locked state and an active state. When the movable component 700 is in the locked state, the rotating base 720 enables the locking pin 710 to engage with one of the fixing slots 311, thereby fixing the position of the headrest 320. The rotating base 720 is rotatably connected to the headrest 320, meaning the rotating base 720 can rotate relative to the headrest 320. When the rotating seat 720 rotates, it can drive the locking pin 710 into or out of the fixing groove 311. It can be understood that a rotating shaft can be provided at the connection between the rotating seat 720 and the headrest 320. When the rotating seat 720 rotates around the rotating shaft and moves away from the headrest 320, it can drive the locking pin 710 out of the fixing groove 311, and the moving component 700 switches from the locked state to the active state. Conversely, when the rotating seat 720 rotates around the rotating shaft and moves closer to the headrest 320, it can drive the locking pin 710 into the fixing groove 311, and the moving component 700 switches from the active state to the locked state.

[0074] Reference Figure 12 , Figure 13 and Figure 14 As shown, in this embodiment of the invention, the pull strap 730 can be threaded through the headrest 320 and connected to the rotating seat 720. It is understood that the user can directly pull the pull strap 730 and move it along the first direction. The pull strap 730 can move along the first direction, and when it does, it can cause the rotating seat 720 to rotate, causing the locking pin 710 to leave the fixing groove 311. The moving component 700 switches from a locked state to an active state. Under the continuous action of the pull strap 730, the headrest 320 can move along the first direction.

[0075] Reference Figure 12 , Figure 13 and Figure 14As shown, in this embodiment of the invention, the headrest 320 may be provided with two slots 321. Specifically, the two slots 321 may be provided at the rear end of the headrest 320, that is, at the end facing the backrest 310. The two slots 321 are spaced apart along a second direction, wherein the second direction is perpendicular to the first direction. The rotating seat 720 may include a main body 721 and two engaging portions 722. The main body 721 is fixedly connected to the pull strap 730. Specifically, the main body 721 may pass through the end of the pull strap 730, or the two may be fixed by other components. This embodiment does not limit this. Two snap-fit ​​parts 722 are located at both ends of the main body 721. The two snap-fit ​​parts 722 correspond one-to-one with the two slots 321. The slots 321 are suitable for inserting the snap-fit ​​parts 722. Based on this, the two snap-fit ​​parts 722 are respectively provided in the two slots 321. The pull strap 730 can drive the snap-fit ​​parts 722 to rotate relative to the slots 321. It can be understood that the rotation axis of the rotating seat 720 is the line connecting the two rotating parts 6431 that are parallel to the second direction.

[0076] Reference Figure 1 and Figure 2 As shown, in this embodiment of the invention, the installation mechanism 800 may include a base 810, a locking element 820, and a locking assembly 830. The base 810 may be provided with a slot suitable for the anchor point in the car seat to enter. The locking element 820 may be provided on the base 810. Specifically, it may be provided at the slot to open or close the slot, thereby fixing and detaching the installation mechanism 800.

[0077] Reference Figure 15 and Figure 16 As shown, in this embodiment of the invention, the locking assembly 830 may include a first button 831, a second button 832, and a stop member 833. The first button 831 and the second button 832 are respectively disposed on both sides of the stop member 833. The first button 831 may have an inclined second sliding groove 8311. The stop member 833 may include a sliding portion 8331 passing through the second sliding groove 8311, and the sliding portion 8331 is slidably connected to the second sliding groove 8311. (Refer to...) Figure 15As shown, since the second slide groove 8311 is inclined, when the first button 831 moves toward or away from the stop member 833, it can drive the sliding part 8331 to move along the second slide groove 8311. It can be understood that the user can press the first button 831 to drive it toward the stop member 833. The second button 832 may include an abutting part 8321 and a driving part 8322. The driving part 8322 can be connected to the locking member 820. It should be noted that the driving part 8322 can be directly connected to the locking member 820 or indirectly connected to it; this embodiment does not limit this. In this embodiment, the stop member 833 can have a first position and a second position. Specifically, the first button 831 can drive the sliding part 8331 to slide along the second slide groove 8311, thereby switching the stop member 833 between the first position and the second position.

[0078] Reference Figure 16 As shown, when the stop 833 is in the first position, the movable part can be located at the top of the second slide groove 8311, and the stop 833 abuts against the abutting part 8321, thus preventing the second button 832 from moving towards the stop 833, thereby preventing the second button 832 from driving the latch 820 to open and reducing the possibility of accidental operation. When the stop 833 is in the second position, the movable part can be located at the bottom of the second slide groove 8311, causing the stop 833 to separate from the abutting part 8321. The stop 833 provides space suitable for the abutting part 8321 to pass through, allowing the second button 832 to move towards the first button 831, thereby driving the latch 820 to open.

[0079] Reference Figure 15 and Figure 16 As shown, in this embodiment of the invention, the first button 831 may be provided with a second receiving groove 8312. The second receiving groove 8312 may be located at one end facing the stop member 833, so that the stop member 833 may be disposed in the second receiving groove 8312, that is, the stop member 833 is located between the two opposite side walls of the second receiving groove 8312. The two opposite side walls of the second receiving groove 8312 are each provided with a second sliding groove 8311. Two sliding parts 8331 may be provided, and the two sliding parts 8331 are respectively disposed at both ends of the stop member 833. The second sliding groove 8311 may be inclined upward in the direction towards the second button 832. That is, when the first button 831 is in the first position, the sliding part 8331 is located at the top of the second sliding groove 8311. When the first button 831 moves toward the stop member 833, the sliding part 8331 moves down to the bottom end of the second sliding groove 8311, and the stop member 833 descends and separates from the abutting part 8321.

[0080] Reference Figure 15 and Figure 16As shown, in this embodiment of the invention, the locking assembly 830 may further include a guide seat 834 disposed within the second receiving groove 8312. The guide seat 834 may include a first guide portion and a second guide portion disposed opposite to each other. The first guide portion may be located at one end near the first button 831, and the second guide portion may be located at one end near the second button 832. The first guide portion and the second guide portion may extend upward to form a guide groove. A stop member 833 is disposed in the guide groove and can move along the guide groove. Specifically, the stop member 833 can rise and fall along the guide groove under the drive of the sliding portion 8331, thereby improving the directional accuracy of the stop member 833's movement.
