Technical Field

[0001] This utility model relates to the field of luggage technology, specifically a safety structure for a foot pedal on a luggage. Background Technology

[0002] Currently, there is a type of scooter case, such as the scooter case disclosed in announcement number CN209617349U. This type of scooter case generally includes a scooter and a case. By combining the scooter and the case to form a scooter case, the functionality of the case is enriched, which is of positive significance.

[0003] The scooter case has two working states. The first state is the scooter state, where the scooter is unfolded and the child can stand on it while holding onto the handlebar on the side of the case. The second state is the case-dragging state, where the scooter's pedals are folded to the back of the case. To achieve the switching between the two states, a folding structure is required. How to prevent accidental operation of the folding structure is a matter of safety and is very important, especially the safety when the scooter is in scooter state.

[0004] The applicant wishes to further enhance security, and therefore proposes a foot pedal safety structure for bags. Utility Model Content

[0005] The technical problem to be solved by this utility model is to overcome the defects of the prior art and propose a safety structure for the pedal of a bag, which is beneficial to prevent accidental folding and especially to improve safety when the scooter is in a certain state.

[0006] Compared with the prior art, this utility model proposes a safety structure for a foot pedal of a bag, including a bag and a foot pedal. The mounting base at the lower end of the bag is rotatably connected to the front end of the foot pedal. The mounting base is provided with an unlocking plate with a seesaw structure that can swing up and down and a latch that can extend and retract in the front and back direction. The latch is connected to a first connecting rod. The front side of the foot pedal is provided with a locking hole that cooperates with the latch. In the initial position, the latch extends backward under the action of the elastic element and engages with the locking hole, and the foot pedal is in the foot pedal scooter state of the bag.

[0007] The unlocking plate, latch, and first connecting rod are all installed in the mounting base, and the upper side of the mounting base is provided with a mating hole. The front end of the unlocking plate is movable and can move up and down with the mating hole, while the rear end of the unlocking plate is located below the upper side and is covered by the upper side. The rear end of the unlocking plate is located on one side of the first connecting rod. When the front end of the unlocking plate is pulled upward, the rear end of the unlocking plate swings downward to drive the first connecting rod forward. The forward movement of the first connecting rod drives the latch forward. The forward movement of the latch unlocks and compresses the elastic element. When the front end of the unlocking plate is released, under the action of the elastic element, the latch re-engages with the lock hole and brings back the first connecting rod. The first connecting rod then drives the rear end of the unlocking plate to swing upward, and the front end of the unlocking plate swings downward back to the initial position.

[0008] In some embodiments, the mounting base includes a top wall, a left wall, a right wall, and a rear wall. The left wall, the right wall, and the rear wall form a circumferential portion. The top wall covers the top of the circumferential portion to form an installation space. The unlocking plate, the latch, and the first connecting rod are all installed in the installation space. The top wall is provided with the aforementioned mating hole. The latch can pass through the rear wall to extend and retract in the front and rear directions.

[0009] In some embodiments, the front end of the pedal is configured as a U-shaped groove, which is swayably sleeved with the circumferential portion. A second connecting rod is provided on the left and right outer sides of the U-shaped groove. The upper end of the second connecting rod on the left side is hinged to the left outer side of the U-shaped groove, and the lower end of the second connecting rod on the left side is hinged to the left wall. The upper end of the second connecting rod on the right side is hinged to the right outer side of the U-shaped groove, and the lower end of the second connecting rod on the right side is hinged to the right wall.

[0010] In some embodiments, a third connecting rod is provided on both the left and right outer sides of the U-shaped groove. The third connecting rod is located behind the second connecting rod. The upper end of the third connecting rod on the left side is hinged to the left outer side of the U-shaped groove, and the lower end of the third connecting rod on the left side is hinged to the left wall. The upper end of the third connecting rod on the right side is hinged to the right outer side of the U-shaped groove, and the lower end of the third connecting rod on the right side is hinged to the right wall.

[0011] In some embodiments, the pedal has a vertically arranged support portion on the rear side of the U-shaped groove, and the support portion has a locking hole at the position corresponding to the tenon, with the tenon and the support portion arranged at right angles.

[0012] In some embodiments, the top of the front end of the latch is provided with a first guide surface, and the lower end of the support is provided with a second guide surface. When the pedal is swung back, the lower end of the support automatically pushes the latch back through the cooperation of the first guide surface and the second guide surface. Then, when the latch is aligned with the lock hole, the latch and the lock hole are automatically re-inserted and engaged.

[0013] In some embodiments, two latches are arranged side by side in the left-right direction and are connected by a first link. The rear end of the unlocking plate swings downward and moves the two latches forward simultaneously through the first link.

[0014] In some embodiments, the top wall is provided with a blocking member that is removably disposed on the upper side of the front end of the unlocking plate.

[0015] In some embodiments, the blocking member is a rotating plate, the front end of which is hinged to the blocking member, and the rear end of which is located above the front end of the unlocking plate.

[0016] With the above structure, compared with the prior art, the present invention has the following advantages: Since the front end of the unlocking plate and the mating hole can move up and down in a movable fit, and the rear end of the unlocking plate is located on the lower side of the upper side and is covered by the upper side, it is not easy to accidentally touch the unlocking plate. At the same time, when the front end of the unlocking plate is pulled up, the rear end of the unlocking plate swings down to drive the first link to move forward. The forward movement of the first link drives the latch to move forward. The forward movement of the latch unlocks and compresses the elastic element. Therefore, in the scooter mode, even if the front end of the unlocking plate is stepped on, the latch will not open, further improving safety.

[0017] Therefore, this utility model provides a safety structure for the pedal of a bag, which helps to prevent accidental folding and is especially beneficial to improving safety when the scooter is in use. Attached Figure Description

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, the above terms should not be construed as limitations on this utility model.

[0029] like Figures 1 to 8 The diagram shows a safety structure for a footrest pedal of a bag, including a bag 1 and a footrest 2. The mounting base 3 at the lower end of the bag 1 is rotatably connected to the front end of the footrest 2. The mounting base 3 is provided with an unlocking plate 4 that can swing up and down like a seesaw and a latch 5 that can extend and retract in the front and back direction. The latch 5 is connected to a first connecting rod 6. The front side of the footrest 2 is provided with a locking hole 7 that cooperates with the latch 5. In the initial position, the latch 5 extends backward under the action of the elastic element 9 and engages with the locking hole 7. The footrest 2 is in the footrest pedal state of the bag 1, and the child can step on the footrest 2 and hold the handlebar 21. When the footrest 2 is flipped around the mounting base 3 and close to the bag 1, it can form a bag dragging state. At this time, the footrest 2 is in the storage state, and the user can drag the bag 1 through the handlebar 21. Therefore, before flipping, the locked state of the latch 5 and the locking hole 7 needs to be unlocked.

[0030] like Figure 1 , 2As shown in Figures 6 and 7, the unlocking plate 4, the latch 5, and the first connecting rod 6 are all installed in the mounting base 3. The upper side of the mounting base 3 is provided with a mating hole 8. The front end of the unlocking plate 4 is movablely engaged with the mating hole 8, allowing it to move up and down. That is, the front end of the unlocking plate 4 extends through the mating hole 8 and can be operated by the user. The rear end of the unlocking plate 4 is located below the upper side and is covered by the upper side. The rear end of the unlocking plate 4 is located on one side of the first connecting rod 6. When the front end of the unlocking plate 4 is pulled upward, the rear end of the unlocking plate 4 swings downward to drive the first connecting rod 6 forward. The forward movement of the first connecting rod 6 drives the latch 5 forward. The forward movement of the latch 5 unlocks the plate and compresses the elastic element 9. When the front end of the unlocking plate 4 is released, under the action of the elastic element 9, the latch 5 re-engages with the lock hole 7 and brings back the first connecting rod 6. The first connecting rod 6 then drives the rear end of the unlocking plate 4 to swing upward, while the front end of the unlocking plate 4 swings downward back to its initial position.

[0031] In this example, as Figure 7 As shown, the mounting base 3 includes a top wall 10, a left wall 11, a right wall 12, and a rear wall 13. The left wall 11, the right wall 12, and the rear wall 13 form a circumferential portion. The top wall 10 covers the top of the circumferential portion to form an installation space. The unlocking plate 4, the latch 5, and the first connecting rod 6 are all installed in this installation space. The unlocking plate 4 is connected to the left wall 11 and the right wall 12 by a hinge shaft 22. The top wall 10 is provided with the aforementioned mating hole 8. The latch 5 can pass through the rear wall 13 to extend and retract in the front and rear directions.

[0032] like Figure 7 , 8 As shown, the left wall 11, right wall 12, and rear wall 13 form a rectangular parallelepiped around the circumferential portion. The front end of the pedal 2 is configured with a U-shaped groove 14, which can be oscillatingly fitted with the circumferential portion. A second connecting rod 15 is provided on both the left and right outer sides of the U-shaped groove 14. The upper end of the second connecting rod 15 on the left side is hinged to the left outer side of the U-shaped groove 14, and the lower end of the second connecting rod 15 on the left side is hinged to the left wall 11. The upper end of the second connecting rod 15 on the right side is hinged to the right outer side of the U-shaped groove 14, and the lower end of the second connecting rod 15 on the right side is hinged to the right wall 12. In this way, on the one hand, since the mounting base 3 needs to accommodate several components, it will have some volume. Therefore, the aforementioned solution facilitates the reciprocating oscillation of the pedal 2 without mutual interference. On the other hand, it also facilitates the assembly of the pedal 2 and the mounting base 3.

[0033] Furthermore, a third link 16 is provided on both the left and right outer sides of the U-shaped groove 14. The third link 16 is located behind the second link 15. The upper end of the third link 16 on the left side is hinged to the left outer side of the U-shaped groove 14, and the lower end of the third link 16 on the left side is hinged to the left wall 11. The upper end of the third link 16 on the right side is hinged to the right outer side of the U-shaped groove 14, and the lower end of the third link 16 on the right side is hinged to the right wall 12. In this way, there are two second links 15 and two third links 16. The second links 15 and the third links 16 together form a four-bar linkage structure, thereby ensuring the flipping trajectory of the pedal 2 and providing stable support from the second links 15 and the third links 16 after it is flipped upright.

[0034] In some embodiments, such as Figure 4 , 6 As shown, the pedal 2 has a vertically arranged support part 17 on the rear side of the U-shaped groove 14. The support part 17 has a locking hole 7 at the corresponding position of the latch 5. The latch 5 and the support part 17 are arranged at right angles. In this way, it has a high locking strength after locking, which is conducive to reliable locking.

[0035] Furthermore, such as Figure 6 As shown, the top front end of the latch 5 is provided with a first guide surface 18, and the lower end of the support part 17 is provided with a second guide surface 19. When the pedal 2 is swung back, the lower end of the support part 17 automatically pushes the latch 5 back through the cooperation of the first guide surface 18 and the second guide surface 19. Then, when the latch 5 is aligned with the lock hole 7, the latch 5 and the lock hole 7 automatically re-engage. In this way, when the pedal 2 is flipped back, it can be automatically locked, which greatly simplifies the user's operation.

[0036] Furthermore, to enhance security, such as Figure 6 As shown, two latches 5 are arranged side by side in the left-right direction, and the two latches 5 are connected by a first connecting rod 6. The rear end of the unlocking plate 4 swings downward and simultaneously drives the two latches 5 forward through the first connecting rod 6. In this way, it has higher strength and more reliable locking of the pedal 2.

[0037] In some embodiments, such as Figure 2 , 7 As shown, the top wall 10 is provided with a blocking member 20, which is removably mounted on the upper side of the front end of the unlocking plate 4. This further enhances the prevention of misoperation and greatly improves safety.

[0038] Furthermore, the blocking member 20 is a rotating plate, the front end of which is hinged to the blocking member 20, and the rear end of which is located above the front end of the unlocking plate 4. This results in a simple structure and convenient manufacturing.

[0039] The above description is merely an illustrative embodiment of this utility model. Therefore, all equivalent changes or modifications made to the structure, features, and principles described in the scope of protection of this utility model are included within the scope of protection of this utility model.
