Description

Technical Field

[0001] This application relates to the field of gas separation technology, and more particularly to a scooter with a lifting riser. Background Technology

[0002] Some existing scooters have handlebars directly fixed to the stem, with no height adjustment, resulting in a poor riding experience for riders of different heights. To address this issue, some scooters use a locking mechanism (based on an eccentric wheel) to adjust the handlebar height. This involves rotating and tightening the handlebar to release or lock the stem, allowing for vertical movement and positioning. However, this design is cumbersome and time-consuming, requiring multiple rotations to tighten the handlebar. Over time, the screws may loosen, causing the handlebar to slip even when locked, requiring tools to re-tighten it. Some scooters have added spring clips and positioning holes for auxiliary positioning, which improves stability but further complicates the process. Tools are needed to press the spring clips to move the handlebar, and multiple presses may be required to skip unwanted positioning holes, making the adjustment process extremely tedious and time-consuming.

[0003] Chinese patent application CN213323501U discloses a foldable electric scooter. The scooter includes a telescopic mechanism and a folding mechanism. The telescopic mechanism includes a pole assembly and elastic positioning elements. The pole assembly includes a pole outer tube and a pole telescopic tube. The pole outer tube has multiple positioning holes. One end of the elastic positioning element is telescopically engaged in the positioning hole, and the other end passes through a side wall hole in the pole telescopic tube and is fixed to the opposite side wall. The telescopic mechanism includes a locking mechanism, a hook, and a locking groove. The pole assembly is rotatably connected to the front fork. A locking mechanism is provided at the connection between the pole assembly and the front fork. The handlebar mechanism has a hook, and the rear wheel mechanism has a locking groove. Although the handlebar height is adjustable, the adjustment is phased and discontinuous. Furthermore, the insertion of the positioning bead into the positioning hole is uncertain, making it difficult to insert it into a suitable height.

[0004] Chinese patent application CN218907511U discloses a push handle height adjustment device and a scooter and a bob handle equipped with the device. The push handle includes a vertical tube that is movable up and down relative to the riser, and a grip connected to the upper end of the vertical tube. The push handle height adjustment device includes a linkage component movably connected to the vertical tube, an operating component movably connected to the push handle, a locking component movably connected to the vertical tube, and multiple mating parts spaced vertically on the riser. When the locking component engages with any mating part, the vertical tube and the riser are positioned at that relative height. The upper side of the linkage component engages with the operating component, and the lower side engages with the locking component. The driving operating component can drive the locking component to disengage from the mating parts via the linkage component, allowing the vertical tube to move up and down relative to the riser. This patent still uses a locking hole for height adjustment, which may cause the push handle to be too high or too low due to hand tremors or other reasons, requiring multiple adjustments. Utility Model Content

[0005] This application provides a scooter with a lifting riser, which at least solves the technical problem of convenient lifting of the riser in the prior art.

[0006] According to a first aspect of this application, a scooter with a rising seat tube is provided, including a seat tube, handlebars, a frame, and wheels. The handlebars are disposed at the upper end of the seat tube, and the lower end of the seat tube is mounted on the frame in a manner that allows it to rotate relative to the frame. The seat tube includes a slide tube, a seat tube, and an adjustment tube. The adjustment tube is mounted on the seat tube in a manner that allows it to rotate relative to the seat tube. A linear track is provided between the slide tube and the seat tube so that the slide tube can move back and forth linearly relative to the seat tube along the linear track. The adjustment tube is threadedly connected to the slide tube so that when the adjustment tube rotates relative to the seat tube, the slide tube moves linearly relative to the seat tube to change the height of the handlebars.

[0007] Compared with the prior art, the scooter with a rising upright in this application has the following advantages: The handlebar height can be controlled by rotating the adjustment tube. The screw-type adjustment makes the height change continuous and the adjustment relatively smooth. A linear track is set between the slide tube and the seat tube to ensure that the slide tube moves in a straight line while maintaining the same angle with the seat tube. That is, when the handlebars are turned, the wheel at the bottom of the seat tube rotates synchronously, ensuring that the height adjustment has the same steering performance. The adjustment tube rotates relative to the seat tube and also rotates relative to the slide tube at the same time, but the seat tube and slide tube maintain the same relative angle, which can adjust the handlebar height while ensuring the steering performance of the handlebars.

[0008] In one embodiment, the slide tube is provided with a first square tube and the seat tube is provided with a second square tube. The first square tube is sleeved outside the second square tube or the second square tube is sleeved outside the first square tube, so that the first square tube can move linearly relative to the second square tube but cannot rotate relative to it. This structure is simple and can realize linear movement.

[0009] In one possible embodiment, the slide tube is sleeved outside the regulating tube and the slide tube has an internal thread that matches the external thread of the regulating tube, or the regulating tube is sleeved outside the slide tube and the regulating tube has an internal thread that matches the external thread of the slide tube.

[0010] In one embodiment, the regulating tube has an external exposed surface, which is knurled or has protrusions to increase friction and facilitate rotation of the regulating tube.

[0011] In one embodiment, the seat tube is provided with an installation section, and the adjusting tube is provided with an annular plate. The annular plate is installed to the installation section by a nut, so that the axial direction of the annular plate is limited by the nut but it can rotate relative to the seat tube. This facilitates the installation of the seat tube and the adjusting tube in a way that allows them to rotate relative to each other.

[0012] In one embodiment, the seat tube adopts a symmetrical design, including an upper mounting section, an upper second square tube, a lower mounting section, and a lower second square tube. The upper second square tube is positioned above the upper mounting section, and the lower second square tube is positioned below the lower mounting section. The upper mounting section, upper second square tube, lower mounting section, and lower second square tube are connected sequentially. The sliding tube includes an upper sliding tube and a lower sliding tube, and the adjusting tube includes an upper adjusting tube and a lower adjusting tube. The upper sliding tube and the upper adjusting tube are installed above the seat tube, and the lower sliding tube and the lower adjusting tube are installed below the seat tube. The upper adjusting tube adjusts the axial position of the upper sliding tube, and the lower adjusting tube adjusts the axial position of the lower sliding tube. This symmetrical design reduces the height of the riser on one side, lowers the torque it bears, and increases the overall strength of the riser. Furthermore, the height can be adjusted on both sides, increasing the height adjustment range.

[0013] In one embodiment, the upper sliding tube and the lower sliding tube are provided with sleeves. The inner wall of the sleeve is provided with anti-rotation grooves that match the protrusions provided with the upper and lower adjusting tubes, so that the protrusions are inserted into the anti-rotation grooves. The sleeve rotates synchronously with the upper and lower adjusting tubes. The rotation directions of the threads of the upper and lower adjusting tubes are opposite, so that when the upper and lower adjusting tubes rotate in the same direction, the upper sliding tube and the lower sliding tube move in opposite directions. In this way, the height is adjusted synchronously up and down, which can achieve rapid height adjustment.

[0014] In one embodiment, a sealing ring is provided at the upper end of the sleeve. The sealing ring is fixed between the upper sliding tube and the sleeve by a sealing cap, so as to lock the sleeve and prevent foreign objects from entering the sleeve.

[0015] In one embodiment, a slide rod is provided on each side of the upper slide tube, and slide rod seats are provided on both sides of the lower slide tube or seat tube so that the slide rod can move linearly within the slide rod seats. Alternatively, a slide rod is provided on each side of the lower slide tube or seat tube, and slide rod seats are provided on both sides of the upper slide tube so that the slide rod can move linearly within the slide rod seats. This allows for more stable linear movement of the upper slide tube.

[0016] According to a second aspect of this application, a scooter with a rising stem is provided, comprising a stem, handlebars, a frame, and wheels. The handlebars are mounted on the upper end of the stem, and the lower end of the stem is rotatably mounted on the frame relative to the frame. The stem includes an upper sliding tube, a lower sliding tube, and an adjusting tube. The adjusting tube covers the upper sliding tube and the lower sliding tube and has an internal thread. Both the upper sliding tube and the lower sliding tube have external threads with opposite directions of rotation. The internal thread of the adjusting tube has two segments with opposite directions of rotation, which respectively match the external threads of the upper sliding tube and the lower sliding tube. A linear track is provided between the upper sliding tube and the lower sliding tube, allowing the upper sliding tube to move linearly relative to the lower sliding tube. This structure is simple and has high strength.

Detailed Implementation

[0021] To make the objectives, features, and advantages of this application more apparent and understandable, the technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0022] Example 1: like Figure 1 and Figure 2 As shown, a scooter with a rising stem includes a stem 1, handlebars 2, frame 3, and wheels 4. The handlebars 2 are located at the upper end of the stem 1, and the lower end of the stem 1 is mounted on the frame 3 in a manner that allows it to rotate relative to the frame 3. The wheels 4 are respectively mounted at the lower end of the stem 1 and below the frame 3, and the wheels 4 below the stem 1 provide steering.

[0023] like Figure 3 and Figure 4As shown, the riser 1 includes a slide tube 11, a seat tube 12, and an adjusting tube 13. The adjusting tube 13 is rotatably mounted on the seat tube 12. A linear track 5 is provided between the slide tube 11 and the seat tube 12, allowing the slide tube 11 to move back and forth linearly relative to the seat tube 12 along the linear track 5. The adjusting tube 13 is threadedly connected to the slide tube 11, so that when the adjusting tube 13 rotates relative to the seat tube 12, the slide tube 11 moves linearly relative to the seat tube 12, changing the height of the handlebar 2. The circular portions of the slide tube 11, seat tube 12, and adjusting tube 13 are coaxially arranged.

[0024] like Figure 4 , Figure 5 and Figure 7 As shown, in one embodiment, the slide tube 11 is provided with a first square tube 51, which is welded and fixed inside the slide tube 11. The seat tube 12 is provided with a second square tube 52, which is welded to the upper end of the seat tube 12. The first square tube 51 is sleeved outside the second square tube 52 or the second square tube 52 is sleeved outside the first square tube 51, so that the first square tube 51 can move linearly relative to the second square tube 52 but cannot rotate relative to it.

[0025] like Figure 4 , Figure 6 and Figure 7 As shown, in one possible embodiment, the slide tube 11 is sleeved outside the adjusting tube 13, and the slide tube 11 has an internal thread that matches the external thread of the adjusting tube 13. The external thread of the adjusting tube 13 is only provided at the end, so that when the adjusting tube 13 rotates, the slide tube 11 does not easily expose the threaded area when it rises, and the range is shorter. The internal thread of the slide tube 11 is designed to be longer, so that the riser 1 has a larger adjustment range.

[0026] like Figure 4 and Figure 6 As shown, in one embodiment, the regulating tube 13 has an external surface 14, which is knurled or has protrusions 15. The rougher the surface of the external surface 14, the greater the friction.

[0027] like Figure 4 and Figure 5 As shown, in one embodiment, the seat tube 12 is provided with an installation section 16, and the adjusting tube 13 is provided with an annular plate 17. The annular plate 17 is installed to the installation section 16 by a nut 7, so that the annular plate 17 is axially limited by the nut 7 but can rotate relative to the seat tube 12. The seat tube 12 can be designed as a solid structure, but this consumes more material; a hollow structure can reduce weight. The outer diameter of the installation section 16 is smaller than the outer diameter of the exposed surface 14.

[0028] like Figure 4 and Figure 5As shown, in one embodiment, the seat tube 12 adopts a symmetrical design, including an upper mounting tube section 21, an upper second square tube 22, a lower mounting tube section 23, and a lower second square tube 24. The upper second square tube 22 is located above the upper mounting tube section 21, and the lower second square tube 24 is located below the lower mounting tube section 23. The upper mounting tube section 21, the upper second square tube 22, the lower mounting tube section 23, and the lower second square tube 24 are connected in sequence. The sliding tube 11 includes an upper sliding tube 18 and a lower sliding tube 19. The adjusting tube 13 includes an upper adjusting tube 30 and a lower adjusting tube 31. The upper sliding tube 18 and the upper adjusting tube 30 are installed above the seat tube 12, and the lower sliding tube 19 and the lower adjusting tube 31 are installed below the seat tube 12. The upper adjusting tube 30 adjusts the axial position of the upper sliding tube 18, and the lower adjusting tube 31 adjusts the axial position of the lower sliding tube 19.

[0029] Example 2: like Figure 8 As shown, the difference from Embodiment 1 is that a slide rod 20 is provided on each side of the upper slide tube 18, and a slide rod seat 10 is provided on both sides of the lower slide tube 19 or seat tube 12 so that the slide rod 20 can move linearly within the slide rod seat 10. Alternatively, a slide rod 20 is provided on each side of the lower slide tube 19 or seat tube 12, and a slide rod seat 10 is provided on both sides of the upper slide tube 18 so that the slide rod 20 can move linearly within the slide rod seat 10.

[0030] Example 3: like Figure 9 , Figure 10 , Figure 11 and Figure 12 As shown, the difference from Embodiment 1 is that the upper sliding tube 18 and the lower sliding tube 19 are provided with a sleeve 6. The inner wall of the sleeve 6 is provided with an anti-rotation groove 32 that matches the protrusion 15 provided in the upper adjusting tube 30 and the lower adjusting tube 31, so that the protrusion 15 is inserted into the anti-rotation groove 32. The sleeve 6 rotates synchronously with the upper adjusting tube 30 and the lower adjusting tube 31. The rotation directions of the threads of the upper adjusting tube 30 and the lower adjusting tube 31 are opposite, so that when the upper adjusting tube 30 and the lower adjusting tube 31 rotate in the same direction, the upper sliding tube 18 and the lower sliding tube 19 move in opposite directions.

[0031] like Figure 11 As shown, a sealing ring 33 is provided at the upper end of the sleeve 6, and the sealing ring 33 is fixed between the upper sliding tube 18 and the sleeve 6 by the sealing cover 34.

[0032] Example 4: like Figure 13As shown, the difference from Embodiment 3 is that the seat tube 12 component is omitted, the upper adjustment tube 30 and the lower adjustment tube 31 adopt an integral structure, the sleeve 6 is set outside the upper slide tube 18, the lower slide tube 19, the upper adjustment tube 30 and the lower adjustment tube 31, the upper slide tube 18 is welded to the inside, the lower slide tube 19 is welded to the inside and fixed to the lower first square tube 54, the upper first square tube 53 is sleeved outside the lower first square tube 54, and the upper slide tube 18 and the lower slide tube 19 achieve relative linear movement through the upper first square tube 53 and the lower first square tube 54 set inside.

[0033] Example 5: like Figure 14 As shown, the difference from Embodiment 1 is that the riser 1 includes an upper sliding tube 18, a lower sliding tube 19, and an adjusting tube 13. The adjusting tube 13 covers the upper sliding tube 18 and the lower sliding tube 19 and has an internal thread. The upper sliding tube 18 and the lower sliding tube 19 both have external threads, and the external threads of the upper sliding tube 18 and the lower sliding tube 19 have opposite directions of rotation. The internal thread of the adjusting tube 13 has two sections with opposite directions of rotation, which respectively match the external threads of the upper sliding tube 18 and the lower sliding tube 19. A linear track 5 is provided between the upper sliding tube 18 and the lower sliding tube 19 so that the upper sliding tube 18 can move linearly relative to the lower sliding tube 19. An upper first square tube 53 is welded inside the upper sliding tube 18, and a lower first square hole 55 is provided inside the lower sliding tube 19. The upper first square tube 53 is installed in the lower first square hole 55. The upper sliding tube 18 and the lower sliding tube 19 achieve relative linear movement through the upper first square tube 53 and the lower first square hole 55.
