[0040] In one embodiment, Figures 1 to 4 As shown, the present application provides a seat tube clamp assembly 300, comprising:

[0041] A wrench kit 310, comprising a wrench 311, a gasket 312, and a pin 313; one end of the wrench 311 is provided with an eccentric wheel;

[0042] The pipe clamp body 320 is rotatably connected to the wrench 311; the pipe clamp body 320 includes an adjusting screw 321, a fixing seat 322, a hanging core 324, and a slider 323; the slider 323 is located between the fixing seat 322 and the hanging core 324; the adjusting screw 321 passes through the opening on the pin 313, the opening on the gasket 312, the opening on the fixing seat 322, the opening on the slider 323, and the opening on the hanging core 324.

[0043] Among them, the eccentric wheel is a mechanical transmission structure; the specific form of the eccentric wheel can be an eccentric structure such as a cam and an eccentric column.

[0044] In some examples, the slider 323 can slide in a first direction; the wrench 311 can flip around a second direction; the hanging core 324 can move in a third direction; the first direction can be specifically expressed as Figures 1 to 4 The X-axis direction shown in FIG. 2 ; the second direction can be specifically expressed as Figures 1 to 4 The Y-axis direction shown in ; the third direction can be specifically expressed as Figures 1 to 4 The Z-axis direction is shown in ; it can be seen that the first direction, the second direction, and the third direction are perpendicular to each other.

[0045] The present application provides a seat tube clamp assembly, comprising: a wrench kit consisting of a wrench with an eccentric wheel at one end, a gasket, and a pin, and a pipe clamp body consisting of a fixed seat, a hanging core, a slider located between the fixed seat and the hanging core, and an adjusting screw that passes through the opening on the pin, the opening on the gasket, the opening on the fixed seat, the opening on the slider, and the opening on the hanging core. In the process of operating the wrench to flip, the eccentric wheel at one end of the wrench will pull the adjusting screw, and the pulled adjusting screw will drive the hanging core to push the slider to move, so as to squeeze the seat tube through the movement of the slider and limit the seat tube from sliding up and down, thereby achieving the effect of locking the seat height. It can be seen that the seat tube clamp assembly provided by the present application can achieve the adjustment of the seat height without using any professional tools, which is not only less difficult to operate, but also more convenient.

[0046] In one embodiment, the eccentric wheel is provided with a central hole.

[0047] In one embodiment, the pin 313 passes through the central hole; there is a gap between the central hole and the pin 313.

[0048] The center hole refers to the center hole provided on the eccentric wheel. By setting a gap between the center hole provided on the eccentric wheel and the pin 313 passing through the center hole, it can be ensured that the pin 313 will not rotate during the rotation of the wrench 311.

[0049] The embodiment of the present application ensures that the pin does not rotate during the rotation of the wrench by setting a gap between the center hole provided on the eccentric wheel and the pin passing through the center hole, thereby effectively ensuring the structural stability of the seat tube clamp assembly.

[0050] In one embodiment, the pipe clamp body 320 is connected to the wrench 311 by rotating the adjusting screw 321 .

[0051] In one embodiment, the opening on the hanging core 324 is a screw hole; and the opening on the slider 323 is a track-shaped hole.

[0052] Specifically, the pipe clamp body 320 can ensure that when the wrench 311 rotates around the second direction (i.e. Figures 1 to 4 During the flipping process (in the Y-axis direction shown in FIG), the eccentric wheel at one end of the wrench 311 will also rotate, so that the adjusting screw 321 can drive the hanging core 324 to the third direction (i.e. Figures 1 to 4 ) to move along the first direction (i.e., the Z-axis direction shown in FIG. 1 ), thereby achieving the goal of pushing the slider 323 along the first direction (i.e., the Z-axis direction shown in FIG. 1 ) through the hanging core 324. Figures 1 to 4 The track-shaped hole on the slider 323 can ensure that the slider 323 slides in the first direction (ie, Figures 1 to 4The screw hole on the hanging core 324 allows the adjusting screw 321 to lock the hanging core 324 after passing through the opening on the pin 313, the opening on the gasket 312, the opening on the fixing seat 322, and the track-shaped hole on the slider 323.

[0053] In one embodiment, at least one of the contact surface between the slider 323 and the fixing seat 322 and the contact surface between the slider 323 and the hanging core 324 is an inclined surface.

[0054] Specifically, at least one of the contact surface between the slider 323 and the fixed seat 322 and the contact surface between the slider 323 and the hanging core 324 is in the form of an inclined surface. Either the contact surface between the slider 323 and the fixed seat 322 or the contact surface between the slider 323 and the hanging core 324 is an inclined surface, or both the contact surface between the slider 323 and the fixed seat 322 and the contact surface between the slider 323 and the hanging core 324 are inclined surfaces.

[0055] The embodiment of the present application effectively ensures the use efficiency of the seat tube clamp assembly by setting at least one of the contact surface between the slider and the fixed seat and the contact surface between the slider and the hanging core as an inclined surface.

[0056] In one embodiment, the eccentric wheel is a cam or an eccentric column.

[0057] In practical applications, the specific form of the eccentric wheel may also be other eccentric structures besides the cam and the eccentric column. The present application does not make any strict limitation on the specific form of the eccentric wheel.

[0058] In one embodiment, the pipe clamp body 320 further includes a fixing screw 500 , and the fixing screw 500 is used to fix the fixing seat 322 .

[0059] In practical applications, the specific fixing position of the fixing screw 500 and the specific number of the fixing screw 500 can be as follows: Figure 2 The form shown (that is, when the fixed seat is as shown Figure 2 When the shape is shown, the specific number of fixing screws 500 can be two, which are respectively fixed on both sides of the fixing seat). The specific fixing position of the fixing screw 500 can also be adjusted accordingly according to the actual shape of the fixing seat, and the specific number of the fixing screw 500 can be set to one or more accordingly. The present application does not strictly limit the specific fixing position of the fixing screw 500 and the specific number of the fixing screw 500.

[0060] In one embodiment, the present application further provides a scooter, comprising a seat 100, a seat tube 200, a frame 400, and a seat tube clamp assembly 300; the seat 100 is connected to the seat tube 200; the seat tube 200 is connected to the seat tube clamp assembly 300;

[0061] The pipe clamp body 320 is sleeved on a connecting end of the vehicle frame 400 .

[0062] Specifically, the specific form of the mobility scooter provided in the present application can be a bicycle, an electric car, a scooter, an electric bicycle, an electric scooter, or other means of transportation with a mobility scooter function. The present application does not make any strict limitations on the specific form of the mobility scooter; the tube clamp body 320 is sleeved on a connecting end of the frame 400, and the tube clamp body 320 can be hidden inside the frame 400 to avoid the influence of the position of the tube clamp body 320 on the adjustable height range of the seat 100, thereby effectively expanding the adjustable height range of the seat 100.

[0063] In addition, a bicycle is a small land vehicle that is powered by human pedaling. It can be used for travel or as a fitness equipment for cycling. Of course, the bicycle itself can also be a sports equipment for road cycling, mountain biking, track biking, stunt biking and other sports competitions.

[0064] In some examples, the present application provides a mobility scooter that can be used as follows: Figures 1 to 3 The one-piece frame shown does not include an independent center tube structure (i.e., the frame body and the center tube are an integrated structure) to enhance the appearance integrity of the frame and reduce the interference of the position of the wrench on the adjustable range of the seat height during the process of lowering the seat height, thereby further expanding the adjustable range of the seat height.

[0065] In one embodiment, the slider 323 is placed inside the frame 400 along the first direction; the adjusting screw 321 passes through the opening on the pin 313, the opening on the gasket 312, the opening on the fixing seat 322, the opening on the slider 323, and the opening on the hanging core 324 in sequence along the third direction; the hanging core 324 is placed inside the frame 400 along the third direction; the first direction and the third direction are perpendicular to each other.

[0066] Further, when the wrench 311 is rotated in the second direction (i.e. Figures 1 to 4 During the flipping process (in the Y-axis direction shown in FIG), the eccentric wheel on one end of the wrench 311 will also rotate. At this time, the outer side of the eccentric wheel away from the center line of the shaft hole can pull the adjusting screw 321 to drive the hanging core 324 to the third direction (i.e. Figures 1 to 4 The hanging core 324 pushes the slider 323 along the first direction (ie, the Z-axis direction shown in FIG. 3 ). Figures 1 to 4 The slider 323 slides along the first direction, and can play the role of squeezing the seat tube 200 and limiting the seat tube 200 from sliding up and down, thereby locking the height of the seat 100.

[0067] It can be seen that when the user uses the seat tube clamp assembly 300 provided by the present application to adjust the height of the seat 100 of the scooter, he only needs to manually operate the wrench 311 to move in the second direction (i.e. Figures 1 to 4 The seat height of the mobility scooter can be easily and conveniently adjusted by flipping the seat in the Y-axis direction (as shown in FIG. 1 ).

[0068] In one embodiment, at least one of the contact surface between the slider 323 and the fixing seat 322 , the contact surface between the slider 323 and the hanging core 324 , and the contact surface between the slider 323 and the seat tube 200 matches.

[0069] Specifically, at least one of the contact surface between the slider 323 and the fixed seat 322, the contact surface between the slider 323 and the hanging core 324, and the contact surface between the slider 323 and the seat tube 200 is matched. It can be that only one or two of the contact surface between the slider 323 and the fixed seat 322, the contact surface between the slider 323 and the hanging core 324, and the contact surface between the slider 323 and the seat tube 200 are matched contact surfaces, or the contact surface between the slider 323 and the fixed seat 322, the contact surface between the slider 323 and the hanging core 324, and the contact surface between the slider 323 and the seat tube 200 are all matched contact surfaces.

[0070] Furthermore, by setting the contact surface between the slider 323 and the fixed seat 322, the contact surface between the slider 323 and the hanging core 324, and the contact surface between the slider 323 and the seat tube 200 to matching contact surfaces, the surfaces that contact each other between the slider 323 and the fixed seat 322, between the slider 323 and the hanging core 324, and between the slider 323 and the seat tube 200 can achieve a tight fit effect, thereby ensuring the use efficiency of the seat tube clamp assembly 300.

[0071] The technical features of the above embodiments can be combined arbitrarily. To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0072] The above-described embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the present application. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application. Therefore, the protection scope of the present application shall be subject to the attached claims.
