[0055] It should be noted that, in the absence of conflict, the features in the embodiments of the present invention may be combined with each other.

[0056] Please refer to Figure 1-Figure 8 This embodiment provides a folder 100, which includes a base 110, a folding main part 120, a trigger assembly 130 and a buffer assembly 140; the base 110 is used to connect with an external pedal body, and the folding main part 120 is used to connect with an external column 210;

[0057] The folding main part 120 and the trigger assembly 130 are both rotatably connected to the base 110, and the axis of rotation of the folding main part 120 relative to the base 110 is parallel to the axis of rotation of the trigger assembly 130 relative to the base 110; the buffer assembly 140 is connected to the folding main part 120 and the trigger assembly 130, and is used to limit the rotation of the folding main part 120 relative to the base 110 toward the side away from the trigger assembly 130;

[0058] The folder 100 has an initial state in which the folding main part 120 , the trigger assembly 130 and the base 110 are closed, and a folding state in which the folding main part 120 is rotated relative to the base 110 toward a side away from the trigger assembly 130 .

[0059] It should be noted that the folder 100 is used for a scooter, and the pedal body of the scooter is connected to the base 110 of the folder 100, and the folding main part 120 of the folder 100 is connected to the tube column 210 of the scooter; therefore, when the folder 100 is in an initial state, that is, a state in which the scooter can be used normally, at which time the tube column 210 of the scooter stands upright on the pedal body, and the folding main part 120, the trigger assembly 130 and the base 110 are in a closed state; and when the folder 100 is in a folded state, the tube column 210 rotates toward the direction of the pedal body to reduce the angle between the pedal body and the tube column 210, so as to facilitate placement or transportation, at which time, the folding main part 120 of the folder 100 rotates toward the side away from the trigger assembly 130, thereby reducing the angle between the pedal body and the tube column 210.

[0060] Please refer to Figure 1-Figure 8 , the working principle of the folder 100 is:

[0061] The folder 100 includes a base 110, a folding main part 120, a trigger assembly 130 and a buffer assembly 140. When the folder 100 is applied to a scooter, the base 110 is connected to the pedal body of the scooter, and the folding main part 120 is connected to the column 210 of the scooter. The folder 100 has an initial state in which the folding main part 120, the trigger assembly 130 and the base 110 are closed, and a folding state in which the folding main part 120 is rotated relative to the base 110 toward a side away from the trigger assembly 130.

[0062] Specifically, since the folding main part 120 and the trigger assembly 130 are both rotatably connected to the base 110, and the axis of rotation of the folding main part 120 relative to the base 110 is parallel to the axis of rotation of the trigger assembly 130 relative to the base 110; therefore, through such a setting, the angle of the column 210 connected to the folding main part 120 relative to the pedal body can be adjusted by the rotation of the folding main part 120 relative to the base 110, so that the scooter equipped with the folder 100 can be switched between the use state and the folding state, so as to facilitate use;

[0063] In the process of converting the scooter using the folder 100 from the use state to the folded state, it is necessary to reduce the angle between the tube column 210 and the pedal body. Due to the weight of the tube column 210 and the structure installed on the tube column 210, the impact force when the tube column 210 rotates toward the pedal body during the conversion process will be too large, which will lead to the risk of damage to the user or the structure of the scooter. Based on this, the folder 100 is equipped with a buffer assembly 140, which is connected to the folding main part 120 and the trigger assembly 130, and is used to limit the rotation of the folding main part 120 relative to the base 110 toward the side away from the trigger assembly 130. Therefore, through the setting of the buffer assembly 140, the rotation of the main assembly relative to the base 110 toward the side away from the trigger assembly 130 can be limited, thereby avoiding the increase of its rotational potential energy, and thus reducing the impact force during the conversion to the folded state.

[0064] Therefore, the folder 100 can play a buffering role during the folding process of the scooter, thereby avoiding excessive impact force during the folding process, and further protecting the user and the structure of the scooter. In addition, it has a simple structure, is easy to install, has a long service life, is simple to maintain, and can effectively reduce the cost of use and maintenance.

[0065] For further information, please refer to Figure 1-Figure 13In this embodiment, when the buffer assembly 140 is provided, the buffer member includes a first connecting shaft 141, a second connecting shaft 142, a connecting rod 143, a connecting sleeve 144 and a connecting rod spring 145;

[0066] Specifically, the first connecting shaft 141 and the second connecting shaft 142 are rotatably connected to the folding main part 120 and the trigger assembly 130 respectively; the connecting rod 143 is connected to the first connecting shaft 141, the connecting sleeve 144 is connected to the second connecting shaft 142, and a part of the connecting rod 143 is slidably matched with the connecting sleeve 144;

[0067] The connecting rod spring 145 is sleeved on the connecting sleeve 144 and the portion of the connecting rod 143 located outside the connecting sleeve 144 , and two ends of the connecting rod spring 145 are respectively connected to the first connecting shaft 141 and the second connecting shaft 142 .

[0068] It can be understood that, through the above-mentioned structural arrangement, when the folding main part 120 rotates relative to the base 110 to convert to the folded state, since the two ends of the connecting rod spring 145 are respectively connected to the first connecting shaft 141 and the second connecting shaft 142, and the first connecting shaft 141 and the second connecting shaft 142 are respectively rotatably connected to the folding main part 120 and the trigger assembly 130, when the folding main part 120 rotates relative to the base 110, it will rotate relative to the trigger assembly 130, and in this way, as the distance between the folding main part 120 and the trigger assembly 130 gradually increases, the connecting rod spring 145 can play a buffering role, and through the arrangement of the connecting rod 143 and the connecting sleeve 144, during the rotation of the folding part, the connecting rod 143 can slide relative to the connecting sleeve 144, which can play a deformation guiding role for the connecting rod spring 145, thereby playing a stable buffering role.

[0069] Furthermore, when configuring the above-mentioned connecting rod 143 , in order to adjust the locking stress of the buffer, the second connecting shaft 142 is provided with a mounting hole 146 , the connecting rod 143 is threadedly connected to the mounting hole 146 , and the outer periphery of the connecting rod 143 is provided with an annular platform 147 for abutting against the connecting sleeve 144 .

[0070] By such a setting, the annular platform 147 located outside the connecting sleeve 144 can be abutted against the end of the connecting sleeve 144, thereby limiting the maximum sliding fit length of the connecting rod 143 and the connecting sleeve 144, thereby limiting the minimum distance between the first connecting shaft 141 and the second connecting shaft 142; in addition, since the connecting rod 143 is threadedly connected to the mounting hole 146, the minimum distance between the first connecting shaft 141 and the second connecting shaft 142 can be adjusted by adjusting the fit length between the connecting rod 143 and the second connecting shaft 142, thereby adjusting the minimum length of the connecting rod spring 145, thereby adjusting the locking force applied by the connecting rod spring 145 between the folding main part 120 and the trigger assembly 130 and the buffering stress of the connecting rod spring 145.

[0071] Further, based on the structure of the above-mentioned buffer assembly 140, when configuring the trigger assembly 130 in this embodiment, the trigger assembly 130 includes a trigger body 131, a first torsion spring 132, an operating wrench 133 and a second torsion spring 134;

[0072] The trigger body 131 is rotatably connected to the base 110. The first torsion spring 132 is disposed at the rotation connection between the trigger body 131 and the base 110 and is used to make the trigger body 131 have a tendency to rotate toward the folding main part 120. The second connecting shaft 142 is rotatably connected to the trigger body 131. In this way, the trigger body 131 can have a tendency to move toward the initial position.

[0073] The operating lever 133 is connected to one end of the trigger body 131 away from the folding main part 120. The second torsion spring 134 is disposed at the rotation connection between the operating lever 133 and the trigger body 131 and is used to make the operating lever 133 have a tendency to rotate toward the folding main part 120.

[0074] One end of the trigger body 131 close to the base 110 is provided with a limit platform 135 which abuts against the base 110 to limit the trigger body 131 from rotating toward the folding main part 120 .

[0075] Through the above-mentioned structural arrangement, the position of the trigger body 131 can be adjusted by operating the wrench 133. In addition, in the present embodiment, since the buffer assembly 140 is connected to the trigger body 131 and the folding main part 120, during the rotation of the folding main part 120 relative to the base 110, an external force rotating in the same direction is applied to the trigger body 131 through the buffer assembly 140. Based on this, one end of the trigger body 131 close to the base 110 is provided with a limit table 135 which abuts against the base 110 to limit the rotation of the trigger body 131 toward the direction of the folding main part 120. It can be understood that when the folder 100 is in the initial state, the limit table 135 of the trigger body 131 is in the position where the limit table 135 and the base 110 are in contact with each other. 10 is in a state of abutment, thereby limiting the rotation of the trigger body 131 toward one side of the folding main component 120. Thus, in this way, during the folding process, when the trigger body 131 is able to return to the initial position under the action of the first torsion spring 132 and the external force of the folding main component 120, the rotation of the trigger body 131 can be limited by the abutment of the limit platform 135 and the base 110, so that it is fixed to the base 110, so that the second connecting shaft 142 connecting the buffer assembly 140 and the trigger body 131 is in a state of unchanged position, and further, when the first connecting shaft 141 increases the distance between it and the second connecting shaft 142 during the rotation of the folding main component 120, the pull rod spring is stretched, thereby playing a buffering role.

[0076] It should be noted that when the operating lever 133 is configured, its function is to facilitate the user to operate the trigger body 131 so as to rotate the trigger body 131 relative to the base 110 , thereby adjusting the position of the trigger body 131 .

[0077] Based on the structure of the trigger assembly 130 described above, please refer to Figure 1-Figure 14 In this embodiment, in order to optimize the structure of the folder 100 and reduce its structural size, the trigger body 131 is provided with a mounting groove 136, and a first connecting portion 137, a receiving groove 138 and a second connecting portion 139 which are sequentially arranged at intervals along the extending direction of the mounting groove 136; the extending direction of the mounting groove 136 is perpendicular to the axis of rotation of the trigger body 131 relative to the base 110;

[0078] The first connecting portion 137 is rotatably connected to the base 110; the second connecting shaft 142 is connected to the second connecting portion 139; the accommodating groove 138 is connected to the mounting groove 136, and the extending direction of the accommodating groove 138 is perpendicular to the extending direction of the mounting groove 136;

[0079] When the folder 100 is in the initial state, the connecting rod 143 , the connecting sleeve 144 and the connecting rod spring 145 are all accommodated in the installation groove 136 , and the second connecting shaft 142 passes through the accommodating groove 138 and cooperates with the accommodating groove 138 .

[0080] Thus, in this way, when the folder 100 is in the initial position, the buffer assembly 140 can be accommodated in the trigger body 131 of the trigger assembly 130, which is beneficial to reducing its structural size. Specifically, when configuring the first connecting portion 137 and the second connecting portion 139, the first connecting portion 137 and the second connecting portion 139 can be arranged on the side wall of the mounting groove 136, so that the second connecting shaft 142 is located in the mounting groove 136; thus, when the folder 100 is in the initial state, the second connecting shaft 142, the connecting rod 143, the connecting sleeve 144 and the connecting rod spring 145 are all accommodated in the mounting groove 136, thereby reducing the structural size of the folder 100 in the initial state; in addition, when the folder 100 is in the initial position, the trigger body 131 is pressed and contacted on the first connecting shaft 141 through its accommodating groove 138, and its force is transmitted to the folding main component 120, so that there is no gap between the folding main component 120 and the base 110, and there is no shaking as a whole.

[0081] Moreover, in this way, when the folder 100 is converted to the folded state, its folding action can be performed in stages, that is, as the folding main part 120 rotates, the connecting rod 143, the connecting sleeve 144 and the connecting rod spring 145 of the buffer assembly 140 accommodated in the installation groove 136 will rotate out of the installation groove 136 as the first connecting shaft 141 rotates relative to the folding main part 120 and the second connecting shaft 142 rotates relative to the trigger body 131. Subsequently, as the folding main part 120 continues to rotate in the same direction, the connecting rod 143 and the connecting sleeve 144 of the buffer assembly 140 are straightened, so that the connecting rod spring 145 can play a buffering role during the rotation of the folding main part 120. That is, from the foregoing content, it can be known that when folding the folder 100, the buffer assembly 140 includes a process of rotating out from the mounting groove 136, and a process of buffering between the folding main component 120 and the trigger body 131. Thus, it is possible to avoid the buffer assembly 140 from continuously buffering during the folding process and increasing the difficulty of folding, thereby improving the folding efficiency.

[0082] Furthermore, in this embodiment, the folding main part 120 is provided with a receiving groove 121, and the first connecting shaft 141 is rotatably connected to the receiving groove 121; wherein, when the folder 100 is in the initial state, the portion of the trigger body 131 having the receiving groove 138 cooperates with the receiving groove 121. Such a setting is the same as the principle of the above-mentioned mounting groove 136, and when the folder 100 is in the initial state, by accommodating a portion of the trigger body 131 in the receiving groove 121, its working principle is consistent with the working principle of the above-mentioned receiving groove 138 on the trigger body 131, thereby reducing the structural size of the folder 100 in the initial state.

[0083] For further information, please refer to Figure 1-Figure 16 In this embodiment, based on the structures of the buffer assembly 140 and the trigger assembly 130, since the scooter is in a normal use state when the folder 100 is in the initial state, in order to limit its state when the folder 100 is in the initial state to prevent the folding main part 120 from being displaced or rotated relative to the base 110, the folder 100 also includes a limit assembly 150, which is connected to the trigger body 131 and is used to limit the rotation of the folding main part 120 relative to the trigger body 131 when the folder 100 is in the initial state.

[0084] Specifically, the limiting assembly 150 includes a limiting rod 151, a limiting spring 152 and a limiting wrench 153;

[0085] The limiting rod 151 and the limiting spring 152 are both connected to the trigger body 131, and the limiting spring 152 is used to make the limiting rod 151 have a tendency to move toward the folding main part 120, and the limiting wrench 153 is connected to the limiting rod 151; the folding main part 120 is provided with at least one limiting groove 122, and the limiting rod 151 is used to engage with the limiting groove 122. It should be noted that when the limiting rod 151, the limiting spring 152 and the limiting wrench 153 are connected to the trigger body 131, a groove body that is slidably matched with the limiting rod 151 and the limiting wrench 153 is provided on the trigger body 131 to guide the limiting rod 151, and the limiting spring 152 and the limiting rod 151 are located in the same groove.

[0086] Through such a setting, when the folding main part 120 is in the initial state, the limit rod 151 can move toward the limit groove 122 under the elastic action of the limit spring 152, and then engage with the limit groove 122, so as to limit the relative movement of the folding main part 120 and the trigger body 131, thereby keeping the folder 100 in the initial state.

[0087] On the basis of the above structure, in this embodiment, when the above-mentioned limiting groove 122 is provided, the folding main part 120 may be provided with a plurality of limiting grooves 122, and the limiting rod 151 is used to engage with one of the limiting grooves 122;

[0088] Moreover, a plurality of limit grooves 122 are sequentially arranged on the end surface of the accommodating groove 121 around the direction in which the folding main component 120 rotates toward the trigger body 131. Thus, through such an arrangement, the angle of the folding main component 120 relative to the base 110 can be limited by cooperating with the limit rod 151 and one of the plurality of limit grooves 122. That is, the limit rod 151 can be abutted against different limit grooves 122, so that the folding main component 120 can be at different angles with the base 110 to meet different usage requirements.

[0089] In the present embodiment, on the basis of providing a plurality of limit grooves 122, taking two limit grooves 122 as an example, one of them is used as a pre-positioning, and the other limit groove 122 is used as the limit groove 122 for positioning the initial state; specifically, the two limit grooves 122 are respectively the first limit groove 122 and the second limit groove 122 in the direction of rotation of the folding main component 120 toward the trigger body 131, and the end surface of the accommodating groove 121 is an arcuate surface arranged around the axis of rotation of the folding main component 120 relative to the base 110. Therefore, when the limit rod 151 is acted upon by the limit spring 152, it will abut against the arcuate surface, and then when the folding main component 120 continues to rotate toward the direction of the trigger body 131. , it will slide into the first limiting groove 122. At this time, the folding main component 120 will be restricted relative to the base 110. In this state, there is a matching angle between the folding main component 120 and the base 110, so there is a matching gap between the two, which will cause shaking. In this case, it is necessary to operate the limiting wrench 153 so that the limiting rod 151 overcomes the elastic force of the limiting spring 152 and moves in the direction away from the base 110, thereby rotating with the first limiting groove 122, and then continue to rotate the folding main component 120, and after releasing the limiting wrench 153, the limiting rod 151 is matched with the second limiting groove 122 under the action of the limiting spring 152, so that the folder 100 can be kept in the initial state. When the limiting rod 151 moves from the first limiting groove 122 to the second limiting groove 122, the first connecting shaft 141 and the accommodating groove 138 on the trigger body 131 are completely fitted and pressed without any gap, thereby achieving the effect of keeping the folder 100 in the initial state to ensure that there is no shaking gap between the folding main part 120 and the base 110 during the use of the scooter.

[0090] In summary, please refer to Figure 1-Figure 16 When the folder 100 is converted from the initial state to the folded state, the operation steps of the folder 100 are as follows:

[0091] First, use the limit wrench 153 to drive the limit rod 151 to disengage from the limit groove 122, thereby releasing the rotation restriction on the folding main component 120;

[0092] Then, the trigger body 131 is rotated toward the side away from the folding main part 120 by operating the wrench 133, so that the limiting rod 151 is separated from the area directly opposite to the limiting groove 122, so as to prevent the limiting rod 151 from engaging with the limiting groove 122 under the action of the limiting spring 152 after the limiting wrench 153 is released;

[0093] Then, the limit wrench 153 is released, and the folding main part 120 is rotated. At this time, the rotation direction of the folding main part 120 is to rotate away from the trigger body 131. At this time, the angle between the pipe column 210 connected to the folding main part 120 and the pedal body connected to the base 110 gradually decreases, so that the size of the scooter on which the folder 100 is installed can be reduced.

[0094] Moreover, during the rotation of the folding main component 120, the buffer assembly 140 can reduce the impact force of the folding main component 120 and the tube column 210 rotating toward the pedal body, thereby playing a buffering role and further protecting the scooter and the user operating the scooter.

[0095] Therefore, the scooter can play a buffering role during the folding process by adopting the folder 100, thereby preventing the impact force from continuing to increase during folding, thereby improving the safety during folding, protecting the display screen assembly and other structures of the scooter, and protecting the user from being injured by the column 210.

[0096] The above are only specific embodiments of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that can be easily thought of by a person skilled in the art within the technical scope disclosed by the present invention should be included in the protection scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the protection scope of the claims.
