[0049] The specific embodiments of the application have been shown by way of example in the above figures, and will be described in more detail hereafter. These figures and this written description are not intended to limit the scope of the inventive concept in any way, but are merely to illustrate the inventive concept by reference to specific embodiments. DETAILED DESCRIPTION

[0050] The exemplary embodiments will be described in detail herein with reference to the attached drawings. The same reference numbers in different drawings represent the same or similar elements. The embodiments described in the following exemplary embodiments are not meant to represent all embodiments consistent with the application. Rather, they are merely examples of apparatus and methods consistent with some aspects of the application as detailed in the appended claims. It is apparent that the described embodiments are a part of the application, and not all embodiments consistent with the application. Based on the embodiments in the application, all other embodiments obtained by those of ordinary skill in the art without creative work are within the scope of protection of the application.

[0051] The vehicle of the application can be a bicycle or an electric bicycle. A bicycle is a small land vehicle that is driven by pedaling with human power. The bicycle can be used as an environmentally friendly means of transportation for walking and traveling, and can also be used as a fitness equipment for riding and exercising. The bicycle itself is also a sports competition, including road bicycle racing, mountain bicycle racing, track bicycle racing, and stunt bicycle racing.

[0052] During cycling, the height of the bicycle seat directly determines the comfort of the people cycling. Therefore, in order to adapt to the differences in height and cycling posture of different users, the height of the seat is usually adjustable. Users can adjust the height of the seat according to their own use requirements, thereby improving the comfort during cycling.

[0053] In the prior art, the device for adjusting the height of the seat is not easy to operate, and different users cannot effectively realize flexible adjustment of the height of the seat according to their own needs, and cannot meet their individual needs.

[0054] Alternatively, in another prior art, a bicycle can be provided with a seat tube clamp for adjusting the height of the seat. When the seat is adjusted to the appropriate height, the seat tube clamp can be used to lock the seat tube connected with the seat. The locking mode of the seat tube clamp and the seat tube is usually to lock by using a screw and a nut pair. However, in the case of using a shared bicycle, the user needs to use a professional tool to lock the screw and the nut to adjust the height of the seat, which is not convenient to operate.

[0055] Based on the above problems, the applicant improves the structure of the existing seat tube clamp device. The locking assembly of the present application includes an eccentric wheel and a sliding block. When the wrench is turned around the first direction, the eccentric wheel of the locking assembly can extrude the sliding block to move in the direction of the seat tube. The sliding block can push the seat tube to limit the upward and downward sliding of the seat tube, thereby realizing the locking of the height of the seat. Therefore, the user can realize the adjustment of the height of the seat without using any professional tool.

[0056] In addition, the contact area between the eccentric wheel and the sliding block of the present application is large, so that the reliability of the interaction between the eccentric wheel and the sliding block during repeated turning of the wrench is high, which is beneficial to improve the service life of the two.

[0057] The seat tube clamp device and the vehicle provided by the present application will be described below with reference to the accompanying drawings and in combination with specific embodiments.

[0058] Referring to Figures 1 to 4 The seat tube clamp device 100 of the embodiment of the present application includes a wrench 110, a tube clamp body 120, and a locking assembly 130.

[0059] Along the first direction X, the wrench 110 includes two side arms 111 arranged oppositely. The tube clamp body 120 is sleeved on the seat tube 200. Along the first direction X, the two side arms 111 are arranged on the two sides of the tube clamp body 120. The side arm 111 is rotatably connected with the tube clamp body 120, and the tube clamp body 120 is provided with a guide cavity 120a. The guide cavity 120a is arranged along the second direction Y.

[0060] The locking assembly 130 comprises a connecting shaft 131, an eccentric wheel 132 and a sliding block 133. The eccentric wheel 132 is sleeved on the outside of the connecting shaft 131. In the first direction X, the connecting shaft 131 penetrates the pipe clamp body 120. The connecting shaft 131 connects the wrench 110 and the pipe clamp body 120. The eccentric wheel 132 and the sliding block 133 are located in the guide cavity 120a. In the second direction Y, the sliding block 133 is located between the eccentric wheel 132 and the seat tube 200. Wherein, the wrench 110 is flipped around the first direction X, so that the eccentric wheel 132 pushes the sliding block 133 to move in the direction of the seat tube 200, so as to lock the seat tube 200.

[0061] In the process of flipping the wrench 110 around the first direction X, the eccentric wheel 132 rotates with the connecting shaft 131. The outer side of the eccentric wheel 132 away from the center line of the shaft hole can push the sliding block 133 to move in the direction of the seat tube 200. The eccentric wheel 132 and the sliding block 133 can slide in the guide cavity 120a along the second direction Y. The sliding block 133 can press the seat tube 200 to limit the up and down sliding of the seat tube 200, so as to realize the locking of the seat height.

[0062] In the present application, the user only needs to manually operate the wrench 110 to flip around the first direction X, so as to realize the adjustment of the seat height. Therefore, the user's way of adjusting the seat height is simple and convenient, which is beneficial to improve the user's experience.

[0063] In addition, the contact between the eccentric wheel 132 and the sliding block 133 in the present application is the contact between the surfaces, so that the possibility of scratching or serious wear affecting the locking effect in the process of pushing the sliding block 133 by the eccentric wheel 132 can be reduced, and the service life of the locking assembly 130 can be improved.

[0064] In some examples, the surface of the eccentric wheel 132 in contact with the sliding block 133 can be matched, so that the surfaces in contact with each other between the eccentric wheel 132 and the sliding block 133 can be matched. Similarly, the surface of the sliding block 133 in contact with the seat tube 200 can be matched, so that the surfaces in contact with each other between the sliding block 133 and the seat tube 200 can be tightly matched.

[0065] Exemplarily, the surface of the sliding block 133 facing the eccentric wheel 132 is an arc surface. The surface of the sliding block 133 facing the seat tube 200 is an arc surface. The sliding block 133 can be made by profile extrusion forming process.

[0066] In some examples, the eccentric wheel 132 can be a cam, an eccentric column or other eccentric structure. In the present application, it is not limited.

[0067] In some realizable ways, referring to Figure 2 and Figure 3As shown, the slider 133 of the embodiment of the present application comprises a first sliding piece 1331 and a second sliding piece 1332. In the second direction Y, the first sliding piece 1331 is located between the second sliding piece 1332 and the seat tube 200. The contact surface of the first sliding piece 1331 and the second sliding piece 1332 is an inclined surface 130a.

[0068] The pipe clamp body 120 can be sleeved on the outside of the seat tube, and the locking assembly 130 can push the seat tube 200 to achieve locking. That is, the pipe clamp body 120, the seat tube 200 and the locking assembly 130 cooperate with each other. Therefore, if the dimensional accuracy consistency of the pipe clamp body 120 and the seat tube 200 is poor, the locking effect is easily affected. Or, after the pipe clamp body 120 is used for many times, there is a gap between the inner wall of the pipe clamp body 120 and the outer wall of the seat tube 200, and when the user operates the wrench 110 to make the eccentric wheel 132 push the slider 133 to move to the preset position, the locking cannot be achieved, that is, the locking effect of the locking assembly 130 is poor or fails. It can be understood that if the saddle slips or rotates during the user's riding, the user's experience is easily poor, and even the safety is easily affected. Or, in order to reduce the occurrence of the above problems, the dimensional accuracy of the pipe clamp body 120 and the seat tube 200 can be improved during the machining process, however, the cost is easily increased.

[0069] In order to solve the above problems, the locking assembly 130 of the embodiment of the present application can have an adjusting compensation function. The first sliding piece 1331 can slide along the inclined surface 130a. After the first sliding piece 1331 slides, the distance between the second sliding piece 1332 and the seat tube 200 in the second direction Y can be increased, so as to compensate for the fitting dimensional gap between the inner wall of the pipe clamp body 120 and the outer wall of the seat tube 200. Therefore, when the eccentric wheel 132 is rotated again to push the slider 133 to move in the direction of the seat tube 200, the locking effect can be achieved. In other words, after the first sliding piece 1331 slides, the wrench 110 will act on the slider 133 in advance during the turning process, and when the wrench 110 reaches the preset position, the seat tube 200 can be locked.

[0070] In some examples, the first sliding piece 1331 and the second sliding piece 1332 can both be made by profile extrusion molding process, so as to reduce the machining process of parts and improve the controllability of precision.

[0071] In some realizable modes, referring to Figure 3 As shown, the inclined surface 130a of the embodiment of the present application faces the seat tube 200. In the third direction Z, the cross-sectional area of the first sliding piece 1331 gradually increases in the direction from the first sliding piece 1331 to the second sliding piece 1332. The cross section is perpendicular to the third direction Z.

[0072] During installation of the seat tube clamp device 100 on the seat tube 200, the cross-sectional size of the first sliding member 1331 can be adjusted to compensate for the gap between the inner wall of the tube clamp body 120 and the outer wall of the seat tube 200.

[0073] In some examples, the first sliding member 1331 slides downward along the inclined surface 130a, and the cross-sectional area of the first sliding member 1331 increases, i.e., along the second direction Y, the distance between the second sliding member 1332 and the seat tube 200 increases to compensate for the gap between the inner wall of the tube clamp body 120 and the outer wall of the seat tube 200.

[0074] In some examples, the seat tube clamp device 100 can be sleeved on the outside of the seat tube 200 along the axial direction of the seat tube 200. That is, the third direction Z can be the same as the axial direction of the seat tube 200. The third direction Z can be a vertical direction. Therefore, referring to Figure 4 As shown, when the user stands on the ground, the downward force is applied to the wrench 110 to make the wrench 110 flip downward around the first direction X to lock the seat tube 200. The operation mode is simple and convenient, and has the effect of saving labor.

[0075] In some examples, the seat tube clamp device 100 can further include shaft sleeves. The shaft sleeves can be sleeved on the outside of the connecting shaft 131. The number of the shaft sleeves can be two. Along the first direction X, the two shaft sleeves can be located on the two sides of the eccentric wheel 132, respectively.

[0076] In some examples, the included angle between the inclined surface 130a and the horizontal plane can be set according to application requirements, for example, the included angle can be 30 degrees. In the present application, it is not limited.

[0077] In some realizable modes, referring to Figure 4 As shown, along the third direction Z, the first sliding member 1331 is provided with a threaded hole 1331a. The second sliding member 1332 is provided with a guide through hole 1332a. The locking assembly 130 can further include an adjusting screw 134. The adjusting screw 134 is arranged at the bottom of the second sliding member 1332. The adjusting screw 134 is arranged through the guide through hole 1332a and the threaded hole 1331a. The adjusting screw 134 can adjust the sliding of the first sliding member 1331 along the inclined surface 130a.

[0078] The depth of the adjusting screw 134 screwed into the first sliding piece 1331 can adjust the upward or downward movement of the first sliding piece 1331 along the inclined surface 130a. The downward sliding of the first sliding piece 1331 can compensate the gap of the fitting dimension between the inner wall of the pipe clamp body 120 and the outer wall of the seat pipe 200. Therefore, when the locking effect of the locking assembly 130 is reduced or lost after long-term use, the maintenance personnel can compensate the gap of the fitting dimension between the inner wall of the pipe clamp body 120 and the outer wall of the seat pipe 200 by adjusting the adjusting screw 134, so that the locking of the seat pipe 200 can be realized when the wrench 110 is operated again. Therefore, the maintenance personnel does not need to replace the entire seat pipe clamp device 100, which is beneficial to improve the work efficiency of the maintenance personnel and reduce the maintenance cost.

[0079] In some examples, along the third direction Z, one end of the adjusting screw 134 can be arranged in the guide through hole 1332a from below the second sliding piece 1332 and connected with the threaded hole 1331a of the first sliding piece 1331.

[0080] In some implementable manners, referring to Figure 4 As shown in the figure, the second sliding piece 1332 of the embodiment of the present application is provided with a limiting portion 1332b. The limiting portion 1332b is arranged close to the large end face of the first sliding piece 1331. The limiting portion 1332b restricts the upward sliding of the first sliding piece 1331 along the inclined surface 130a.

[0081] The downward sliding of the first sliding piece 1331 of the present application compensates the gap of the fitting dimension between the inner wall of the pipe clamp body 120 and the outer wall of the seat pipe 200, therefore, the limiting portion 1332b can effectively reduce the possibility that the compensation effect is lost due to the upward sliding of the first sliding piece 1331.

[0082] In some examples, the limiting portion 1332b can be but is not limited to a strip-shaped structure. The shape of the limiting portion 1332b is not limited in the present application.

[0083] In some implementable manners, referring to Figure 2 As shown in the figure, the pipe clamp body 120 of the embodiment of the present application comprises a first guide plate 121 and two second guide plates 122 oppositely arranged along the first direction X. The first guide plate 121 is located between the two second guide plates 122. The first guide plate 121 connects the two second guide plates 122, and the first guide plate 121 and the second guide plates 122 together enclose a guide cavity 120a.

[0084] The eccentric wheel 132 and the sliding block 133 of the embodiment of the present application are located in the guide cavity 120a. The two second guide plates 122 can restrict the pushing of the eccentric wheel 132 to move the sliding block 133 along the second direction Y.

[0085] In some examples, referring to Figure 2As shown, the pipe clamp body 120 can further include a ring body 123. The ring body 123 can be sleeved on the outside of the seat pipe 200. The first guide plate 121 and the second guide plate 122 are connected with the ring body 123. The second guide plate 122 is provided with a through hole along the first direction X. The connecting shaft 131 can be inserted into the through hole to connect the pipe clamp body 120 and the wrench 110.

[0086] In some possible implementation manners, referring to Figure 2 As shown, the pipe clamp body 120 has an opening 120b. The opening 120b is oppositely arranged with the first guide plate 121. The seat pipe clamp device 100 further includes a lower baffle 140. The lower baffle 140 blocks the opening 120b.

[0087] The sliding block 133 can be put into the guide cavity 120a through the opening 120b. The lower baffle 140 can block the opening 120b to restrict the sliding of the sliding block 133 along the first direction X.

[0088] In some examples, the opening 120b can be downward along the third direction Z. The lower baffle 140 can be provided with a relief groove. The relief groove can be used to avoid the head of the adjusting screw 134. The head of the adjusting screw 134 is exposed, which can facilitate the maintenance personnel to adjust the compensation amount. The maintenance personnel can adjust the adjusting screw 134 without disassembling the lower baffle 140, which is beneficial to reduce the difficulty of the maintenance work of the maintenance personnel. In addition, since the opening 120b is downward, even if the adjusting screw 134 is exposed, it is not easy to find, and thus the possibility of human damage can be reduced.

[0089] In some examples, the lower baffle 140 and the pipe clamp body 120 can be detachably connected. The lower baffle 140 and the pipe clamp body 120 can be detachably connected through screws.

[0090] In some possible implementation manners, the cross-sectional shape of the connecting shaft 131 of the embodiment of the present application can be formed by at least one of a straight line and a curve. The cross-sectional shape of the inner hole of the eccentric wheel 132 matches the cross-sectional shape of the connecting shaft 131, and the cross section is perpendicular to the second direction Y.

[0091] The embodiment of the present application further provides a vehicle. The vehicle includes the seat pipe 200 and the seat pipe clamp device 100. Referring to Figure 1 As shown, the seat pipe 200 includes an outer pipe 210 and a middle pipe 220. The pipe clamp body 120 is arranged on the outer pipe 210. The eccentric wheel 132 presses the sliding block 133 to make the sliding block 133 abut against the middle pipe 220.

[0092] The vehicle of the present application can be a bicycle or an electric vehicle. The electric vehicle can be an electric bicycle. In the present application, no specific limitation is made.

[0093] In some examples, one end of the middle tube 220 is connected with the seat along the third direction Z. Part of the middle tube 220 is located in the outer tube 210, so that the middle tube 220 can slide along the axial direction of the outer tube 210, thereby adjusting the height of the seat. When the seat is adjusted to a suitable height of the user, the wrench 110 is flipped down, so that the eccentric wheel 132 pushes the slider 133 to move in the direction of the middle tube 220. The slider 133 can press the middle tube 220 to constrain the up and down movement of the middle tube 220, thereby achieving the locking of the height of the seat.

[0094] When the wrench 110 is flipped down to the maximum position and cannot achieve locking due to processing errors or long-term use of the seat tube clamp device 100, the maintenance personnel can not need to disassemble the entire seat tube clamp device 100, but can adjust the depth of the adjusting screw 134 screwed into the first slider 1331, so as to compensate for the gap between the inner wall of the tube clamp body 120 and the outer wall of the middle tube 220, thereby achieving the reuse of the seat tube clamp device 100.

[0095] In some examples, the middle tube 220 can be provided with an adjusting slot. The adjusting slot is arranged along the third direction Z. The sidewall of the tube clamp body 120 is provided with a connecting through hole. The connecting through hole corresponds to the adjusting slot. The vehicle further comprises a seat tube limiting screw 300. The seat tube limiting screw 300 is arranged in the connecting through hole. The tail end of the seat tube limiting screw 300 is located in the adjusting slot.

[0096] The connecting through hole can be arranged on the sidewall of the ring body 123 of the tube clamp body 120. The seat tube limiting screw 300 can be arranged in the connecting through hole of the ring body 123, so that the tail end of the seat tube limiting screw 300 can be located in the adjusting slot, thereby reducing the possibility of the middle tube 220 continuously sliding upward and being separated from the outer tube 210.

[0097] In some examples, the ring body 123 can further be provided with a locking mounting hole. The locking mounting hole is arranged along the third direction Z. The locking mounting hole is in communication with the connecting through hole. The vehicle can further comprise a locking screw 400. The locking screw 400 can abut against the seat tube limiting screw 300 through the locking mounting hole, so that the seat tube limiting screw 300 is not easy to be separated from the connecting through hole.
