Description

Technical Field

[0001] This utility model relates to the field of scooter technology, and more specifically, to a scooter handlebar stem with a storage function. Background Technology

[0002] Scooters have become increasingly popular due to their small size, light weight, and compact folding design. However, some shortcomings have also become apparent during scooter use, particularly compared to bicycles. Traditional scooters lack storage space for personal items. In daily riding, we often encounter situations where we need something, such as a drink of water or an umbrella in the rain. While these items can be carried in a bag, some cyclists prefer not to carry a backpack. Therefore, designing storage space on the scooter for essential items would be very convenient for riders and greatly enhance the riding experience.

[0003] To address the above issues, this utility model provides a scooter handlebar stem with storage function. It can provide space to store common items such as umbrellas, water bottles, and other frequently used items without increasing the scooter's external space, bringing convenience to riders. Utility Model Content

[0004] The purpose of this utility model is to provide a scooter stem with storage function. It innovates the original stem structure without increasing the scooter's outward space, allowing for additional storage space to carry frequently used items such as umbrellas and water bottles, thus providing convenience for riders.

[0005] The embodiments of this utility model can be implemented as follows:

[0006] A scooter handlebar stem with storage function, characterized in that the scooter handlebar stem comprises:

[0007] The handlebar stem assembly is located in the upper section of the overall handlebar stem and has an internal cavity for storing items such as umbrellas.

[0008] A support stem assembly is provided, located at the lower section of the overall stem. The upper end of the support stem assembly is fixedly connected to the lower end of the storage stem assembly. The lower end of the support stem assembly is inserted into the scooter's connecting base, causing the scooter's front wheel to steer.

[0009] Furthermore, the storage handle tube assembly includes: an outer tube sleeve, a horizontal handle assembly, and a display screen. The upper end of the outer tube sleeve is provided with a horizontal protrusion. The display screen is fixed above the horizontal protrusion and the horizontal handle assembly is fixed below it. The outer tube sleeve is a hollow cylinder with a storage sleeve inside.

[0010] Furthermore, the storage sleeve can slide up and down inside the outer sleeve, and a ratchet mechanism is provided below the storage sleeve.

[0011] Furthermore, the ratchet mechanism includes a ratchet housing, a stationary ratchet, a movable ratchet, and a spring, wherein the stationary ratchet, the movable ratchet, and the spring are arranged in order from top to bottom inside the ratchet housing;

[0012] The inner wall of the ratchet housing is uniformly provided with grooves along the circumferential direction, and the adjacent grooves form a locking part. Each locking part has a large wedge-shaped surface and a small wedge-shaped surface at its end face. The end of the small wedge-shaped surface is smoothly connected to the groove, and the end of the large wedge-shaped surface is blocked.

[0013] The upper end of the stationary ratchet is fixedly connected to the lower end of the storage sleeve. The stationary ratchet has a protrusion along the circumferential direction. The protrusion is engaged in the groove of the ratchet housing. The stationary ratchet can slide up and down along the groove, but cannot rotate around its own axis due to the engagement of the groove. The lower end face of the stationary ratchet is evenly provided with ratchet teeth along the circumferential direction. The tooth tip of the ratchet teeth is aligned with the center line of the protrusion. A movable ratchet is provided below the stationary ratchet.

[0014] The movable ratchet also has a protrusion along the circumferential direction, called the second protrusion. The upper end of the second protrusion has a wedge-shaped surface. The second protrusion is also engaged in the groove. The movable ratchet slides up and down along the groove, but it cannot rotate around its own axis because of the engagement of the groove unless the second protrusion is completely disengaged from the groove. A spring is provided below the movable ratchet.

[0015] Furthermore, the ratchet mechanism has two states: open and closed, which switch sequentially in a loop.

[0016] Furthermore, the support stem assembly includes a support tube, and a battery unit may be provided in the inner cavity of the support tube. The upper end of the battery unit is fixedly connected to the ratchet housing. If the inner cavity of the support tube does not have a battery unit, the ratchet housing is directly fixedly connected to the support tube.

[0017] Furthermore, an item, such as an umbrella, is placed inside the storage sleeve, with the upper surface of the umbrella flush with the upper end face of the outer sleeve. When the ratchet mechanism is in the closed state, pressing down on the upper surface of the umbrella triggers the ratchet mechanism to open, causing the spring in the ratchet mechanism to push the storage sleeve upward, thereby moving the umbrella upward and making it protrude from the storage cavity for easy removal. When the umbrella is pressed down again until the ratchet mechanism closes, the upper surface of the umbrella is flush with the upper end face of the outer sleeve again, and the cycle repeats.

[0018] Furthermore, since the inner diameter of the lower end of the outer sleeve is larger than the outer diameter of the support tube, a connecting sleeve is provided at the connection of the two tubes. The connecting sleeve has a connecting hole on its side wall, and the outer sleeve and the support tube also have connecting holes at corresponding positions. The three are fixed together by fastening screws.

[0019] In summary, the ratchet mechanism allows for easy ejection or locking of items from the storage compartment, and the stored items are concealed, without affecting the scooter's appearance or other functions. Attached Figure Description

[0032] In the description of this utility model, it should be noted that if terms such as "upper," "lower," "inner," or "outer" are used to indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship in which the utility model product is usually placed during use, 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, and therefore should not be construed as a limitation of this utility model.

[0033] Furthermore, the terms "first" and "second" are used only to distinguish descriptions and should not be interpreted as indicating or implying relative importance.

[0034] It should be noted that, where there is no conflict, the features in the embodiments of this utility model can be combined with each other. The specific drawings are described below.

[0035] Figure 1 The figure shows a perspective view of the scooter handlebar stem 10 installed on the scooter 1.0 according to an embodiment of the present invention. As shown, the scooter handlebar stem 10 is located at the front of the scooter 1.0, and the lower end of the stem is inserted into the scooter connecting base to drive the front wheel of the scooter to turn.

[0036] Figure 2 The figure shows a perspective view of the scooter handlebar stem 10 provided in an embodiment of the present utility model. The scooter handlebar stem 10 is composed of a handlebar stem storage assembly 100 located at the upper part and a handlebar stem support assembly 200 located at the lower part.

[0037] Figure 3 The exploded view of the scooter handlebar stem 10 provided in this embodiment of the utility model is shown in the figure. The main part of the handlebar stem storage assembly 100 is the outer tube sleeve 102. The inner cavity 1021 of the outer tube sleeve is hollow and can be used as a storage cavity. The upper end of the outer tube sleeve 102 is provided with a horizontal protrusion 1022. The horizontal protrusion 1022 is provided with a display screen 1023 on the top and a horizontal handlebar assembly 1024 below. The inner cavity 1021 of the outer tube sleeve is provided with a storage sleeve 103. The storage sleeve 103 is also hollow. Its inner cavity can be used to store items. The item to be stored in the figure is an umbrella 101. Of course, it can also be a water bottle or other commonly used cycling items. In order to prevent the item from rotating in the storage sleeve 103, the end cap of the item is designed as a non-rotating body shape, and the upper surface of the end cap is flat so as to be flush with the upper end surface of the outer tube sleeve.

[0038] The lower end of the storage sleeve is provided with a ratchet mechanism 110, which includes a ratchet housing 111, a stationary ratchet 112, a movable ratchet 113, and a spring 114. The ratchet mechanism 111 is used to control whether the storage sleeve is in an extended or retracted state. The stationary ratchet 112 is provided with a first connecting thread 1123 on its upper part, which fixes the storage sleeve 103 and the stationary ratchet 112 together.

[0039] The support handlebar stem assembly 200 mainly consists of an external support handlebar stem 201 and a battery unit 202 located inside it. The upper end of the battery unit 202 is provided with a second connecting thread 2021, which is used to fix the ratchet housing 111 and the battery unit 202 together. It should be noted that if the support handlebar stem assembly 200 does not have a battery unit inside, and the battery unit is located inside the scooter foot pedal, then the ratchet housing 111 is directly fixed to the support handlebar stem 201.

[0040] Since the inner diameter of the outer sleeve 102 is much larger than the outer diameter of the support handlebar stem 201, there will be a large gap when the two tubes are inserted. Therefore, a connecting sleeve 120 is provided at the connection point. The side wall of the connecting sleeve 120 is provided with a connecting side hole 121. The support handlebar stem 201 and the outer sleeve are also provided with connecting holes at corresponding positions. The three are fixedly connected together by connecting screws 130.

[0041] Figure 4 This is a schematic diagram of the internal component connections of the scooter handlebar stem 10 provided in this embodiment of the utility model. The diagram omits the outer sleeve 102 and the support stem 201. As shown, the umbrella 101 is inserted into the storage sleeve 103. Because the umbrella fabric of the umbrella 101 is made of soft material, it tends to expand outwards even when folded. Therefore, the storage sleeve 103 is needed to wrap around the umbrella 101; otherwise, the expansion of the fabric will cause friction with the inner wall of the outer sleeve 102, affecting the sliding of the umbrella 101 in the storage cavity 1021. Therefore, the storage sleeve 103 is added. Below the storage sleeve 103 are the ratchet housing 111 and the battery unit 202.

[0042] Figure 5 The figure shows a cross-sectional view of the ratchet mechanism of the scooter handlebar stem 10 provided in this embodiment of the invention. The storage sleeve 103 is fixedly connected to the stationary ratchet 112 via a first connecting thread 1123. Therefore, when the storage sleeve 103 and the umbrella 101 slide up and down in the storage cavity 1021, they will cause the stationary ratchet 112 to slide up and down in the ratchet housing 111. The ratchet housing 111 is fixedly connected to the battery unit 202 via a second connecting thread 2021.

[0043] Figure 6 This is an exploded view of the ratchet mechanism of the scooter handlebar stem provided in this embodiment of the utility model. The structural features of each part in the ratchet mechanism are described below.

[0044] First, the inner wall of the ratchet housing 111 is uniformly provided with grooves 1111 along the circumferential direction. The adjacent grooves 1111 form a locking part. Each locking part has a large wedge-shaped surface 1112 and a small wedge-shaped surface 1113 at its end face. The end of the small wedge-shaped surface 1113 smoothly transitions into the groove 1111, and the end of the large wedge-shaped surface is blocked. The stationary ratchet 112 is provided with a protrusion 1121 along the circumferential direction. The protrusion 1121 is locked in the groove 1111 of the ratchet housing 111. Therefore, the stationary ratchet 112 can slide up and down along the groove 1111. However, because the locking part is locked, it cannot rotate around its own axis. The lower end face of the stationary ratchet 112 is uniformly provided with ratchet teeth along the circumferential direction. The tooth tip 1122 of the ratchet teeth is aligned with the center line of the protrusion 1121. A moving ratchet 113 is provided below the stationary ratchet 112.

[0045] The movable ratchet 113 also has a protrusion along the circumferential direction, referred to as the second protrusion 1131. The upper end of the second protrusion 1131 is provided with a wedge-shaped surface 1132. The second protrusion 1131 is also engaged in the groove 1111. The movable ratchet 113 can also slide up and down along the groove 1111. However, due to the engagement of the engagement part, it cannot rotate around its own axis unless the second protrusion 1131 is completely disengaged from the groove 1111. A spring 114 is provided below the movable ratchet 113.

[0046] The working principle of the ratchet mechanism 110 will be explained next:

[0047] The ratchet mechanism 110 has two states, one open and one closed, corresponding to the extension and retraction of the storage sleeve 103 and the umbrella 101. When the protrusions of the stationary ratchet 112 and the moving ratchet 113 are both within the groove 1111, the protrusions of the two ratchets are aligned. It should be noted that one of the structural features of the stationary ratchet 112 is that the protrusion 1121 is aligned with the tooth tip 1122 of the ratchet on the end face in the circumferential direction. Therefore, at this time, the wedge-shaped surface 1132 of the second protrusion 1131 of the moving ratchet 113 is just engaged with the tooth tip 1122 of the stationary ratchet 112. This state is unstable. When a person presses the end cap of the umbrella 101, the umbrella 101 and the storage sleeve 103 together push the stationary ratchet 112 to slide down along the groove 1111. The movable ratchet 113 is also pushed down. When the second protrusion 1131 of the movable ratchet 113 is pushed away from the groove 1111, as previously analyzed, the wedge-shaped surface 1132 at the upper end of the second protrusion 1131 is unstable when it is engaged with the tooth tip 1122 of the ratchet. Therefore, the component force of the wedge-shaped surface 1132 will force the movable ratchet 113 to rotate at a certain angle. At the same time, because the stationary ratchet 112 and the movable ratchet 113 slide down in the groove 1111, the spring 114 is compressed.

[0048] Immediately afterward, when the pressure on the umbrella 101 is released, the lowest spring 114 reacts, forcing the moving ratchet 113 and the stationary ratchet 112 to slide upwards. Because the moving ratchet 113 has already rotated axially, its second protrusion 1131 is no longer aligned with the groove 1111, but instead slides into the wedge-shaped surface at the end face of the ratchet housing 111. The wedge-shaped surface is divided into large and small wedge-shaped surfaces, with one end of the large wedge-shaped surface 1112 closed. As long as the small wedge-shaped surface 1113 is smoothly connected to the groove 1111, when the second protrusion 1131 of the moving ratchet 113 slides into the large wedge-shaped surface 1112, it will get stuck at the end of the large wedge-shaped surface 1112. Only when it slides into the small wedge-shaped surface 1113 can it return to the groove 1111. When the second protrusion 1131 of the moving ratchet 113 engages with the large wedge-shaped surface 1112, the ratchet mechanism 110 is in the closed state. At this time, the storage sleeve 103 and the umbrella 101 retract into the storage cavity 1021, and the upper surface of the umbrella 101 end cap is flush with the upper surface of the outer tube sleeve 102. When the second protrusion 1131 of the moving ratchet 113 engages with the small wedge-shaped surface and then slides into the groove 1111, the ratchet mechanism 110 is in the open state. At this time, the storage sleeve 103 and the umbrella 101 slide upward, and the end cap of the umbrella is protruded, making it convenient for the cyclist to take out the umbrella. The on / off state of the ratchet mechanism 110 can be switched sequentially, so that the end cap of the umbrella 101 protrudes from or is flush with the upper surface of the outer tube sleeve 102, repeating the cycle.

[0049] In summary, the ratchet mechanism allows cyclists to easily take out or put away their umbrellas. In this embodiment, the umbrella can also be replaced with a water bottle or other commonly used cycling items.

[0050] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
