Description
Technical Field
[0001] This utility model relates to the technical field of electric bicycle battery box connecting components, specifically to a limiting mechanism and an electric bicycle containing the same. Background Technology
[0002] With the advancement of technology and the popularization of environmental protection concepts, electric bicycles have gradually become an important means of transportation. To improve the neatness and aesthetics of electric bicycles, most electric bicycles now have their battery boxes installed in the frame. However, most battery boxes are currently fixed by directly screwing the base of the battery box to the frame. As electric bicycles are used, wear and tear can easily occur at the frame and screw fastening point, leading to loosening of the battery box and its internal components.
[0003] Based on this, some manufacturers have also improved the stability of the internal components of the battery box and the connection between the battery box and the vehicle frame by adding welding seats to the bottom of the battery box base. However, this method increases the cost and difficulty of assembling electric bicycles, and can only guarantee vertical stability. Secondly, welding is irreversible, and it is difficult to maintain the original stability after disassembly and maintenance, and it will cause structural damage to the vehicle frame and other components. Utility Model Content
[0004] This utility model provides a limiting mechanism and an electric bicycle containing the same, to solve the problem that the battery box fixing method in the prior art easily leads to the loosening of the battery box and its internal components.
[0005] To solve the above-mentioned technical problems, the present invention provides a limiting mechanism, which includes a first boss, a second boss, a limiting seat, and a locking member.
[0006] The first boss includes a first body and a first protrusion; the second boss includes a second body and a second protrusion; the limiting seat is provided with a first opening and a second opening at intervals along a first direction, wherein the first protrusion is used to insert into the first opening along a second direction, and the second protrusion is used to insert into the second opening along the second direction; the plurality of locking members are respectively connected to the first boss, the second boss and the limiting seat along the second direction.
[0007] The beneficial effects of the technical solution provided by this utility model compared to the prior art are as follows:
[0008] By nesting the first protrusion and the second protrusion with the limiting seat respectively (i.e., the first protrusion is inserted into the first opening and the second protrusion is inserted into the second opening), the first protrusion, the limiting seat and the second protrusion form a mutually overlapping form, thereby ensuring that the battery box is counteracted in the first direction (horizontal direction) by the first protrusion and the second protrusion, thus ensuring the horizontal positioning of the electric bicycle's battery box.
[0009] The locking component connects the first boss, the second boss, and the limiting seat along the second direction (vertical direction) to ensure the tight connection and limiting of each component in the vertical direction. The locking component can also connect to the external vehicle frame to ensure the stable fixation of the battery box in the vertical direction.
[0010] Furthermore, the nested structure of the first boss, the second boss, and the limiting seat effectively avoids the use of welding processes, thus simplifying subsequent installation and disassembly operations. The nested connection between the first boss, the second boss, and the limiting seat effectively reduces the space occupied by the battery box while ensuring the strength and stability of the internal components of the battery box and the connection between the battery box and the electric bicycle.
[0011] In some embodiments, the locking member includes a plurality of first locking members and a plurality of second locking members, wherein the plurality of first locking members are used to insert into the upper surface of the limiting seat along the second direction, and the plurality of second locking members are used to insert into the lower surface of the limiting seat along the second direction, and respectively lock with the first body or the second body.
[0012] By adopting the above technical solution, the upper part of the limiting seat is connected to the first locking member, enabling the locking mechanism to connect with and fix the internal components of the battery box. The lower part of the limiting seat is fixed by the second locking member, allowing the locking mechanism to be stably connected to the electric bicycle outside the battery box. The first and second locking members work together to form a double lock in the second direction, ensuring the stability of the battery box and improving the convenience of subsequent maintenance.
[0013] In some embodiments, the limiting seat is further provided with a receiving chamber communicating with the second opening, wherein the second protrusion extends through the second opening along the second direction and is located in the receiving chamber to further improve the connection tightness between the second protrusion and the limiting seat, and to ensure further limiting of its battery box in the third direction.
[0014] In some embodiments, the limiting seat is further provided with a first groove, which is recessed into the receiving cavity; wherein, the second protrusion is provided with a second groove corresponding to the first groove, so that when the second protrusion is located in the receiving cavity, the first groove can be embedded in the second groove.
[0015] By adopting the above technical solution, an additional locking structure is provided by nesting the first groove and the second groove, which further ensures that the second protrusion is fixed in position within the accommodating space and prevents loosening that may be caused by vibration of the battery box.
[0016] In some embodiments, the limiting seat is further provided with a stop bar located on the outer periphery of the first opening. Since the first protrusion is not located within the enclosed space, adding the stop bar can provide additional limiting effect for the first protrusion.
[0017] In some embodiments, the first protrusion is further provided with a plurality of guide strips along the first direction toward the side of the second protrusion. The guide strips are spaced apart on both sides of the first body along a third direction, and the plurality of guide strips are provided to facilitate the positioning and installation of the first protrusion.
[0018] In some embodiments, the limiting mechanism further includes a fixing bracket located between the first boss and the second boss along the first direction, wherein the fixing bracket further includes a limiting post extending along the second direction and connected to the first boss.
[0019] Furthermore, the first locking member passes through the fixing bracket along the second direction and is inserted into the upper surface of the limiting seat.
[0020] Using the above technical solution, the fixing bracket is used to install and fix the main components of the battery box, such as locks and charging components. Setting it between the first boss and the second boss can effectively limit the fixing bracket, thereby further ensuring the stability of the internal components of the battery box.
[0021] In some embodiments, the first protrusion is further provided with a locking groove along the first direction toward the second protrusion. The locking groove can engage with the locking tongue located on the fixing bracket to achieve mechanical locking of the battery box and prevent the battery box from being abnormally removed. Furthermore, placing the locking groove on the first protrusion effectively ensures that the battery box can be mechanically locked to the electric bicycle.
[0022] In some embodiments, this application also provides an electric bicycle, including the aforementioned limiting mechanism, battery box, and frame, wherein the limiting mechanism is located inside the battery box, the frame is a hollow structure, and the second locking member of the limiting mechanism penetrates the upper surface of the frame and locks with the limiting seat.
[0023] By adopting the above technical solution, the aforementioned limiting mechanism effectively ensures the stability of the battery box relative to the vehicle frame in both the horizontal (front-back, left-right) and vertical directions, thereby effectively preventing internal components from loosening or falling off during use. Furthermore, the limiting mechanism is integrated into the battery box design, ensuring the overall aesthetics of the electric bicycle. Attached Figure Description

[0034] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.
[0035] For ease of subsequent description, this application will first combine [the following descriptions] before describing the specific structure of the limiting mechanism. Figure 3 A first direction (X), a second direction (Z), and a third direction (Y) are defined. The first direction is the length direction of the limiting mechanism when it is normally positioned, such as the X direction; the second direction is the height direction of the limiting mechanism when it is normally positioned, such as the Z direction; and the third direction is the width direction of the limiting mechanism when it is normally positioned, such as the Y direction. In this application, the first direction (X), the second direction (Z), and the third direction (Y) are perpendicular to each other.
[0036] It is understood that the mutual perpendicularity in this application is not absolute perpendicularity. Approximate perpendicularity due to processing errors and assembly errors (e.g., the included angle between two structural features is 89.9°) is also within the scope of mutual perpendicularity in this application.
[0037] See Figures 1 to 3 As shown, Figure 1 An exploded view of an embodiment of a limiting mechanism provided in this application is shown; Figure 2 This paper shows a cross-sectional structural schematic diagram of an embodiment of a limiting mechanism provided in this application; Figure 3 A three-dimensional structural schematic diagram of an embodiment of a limiting mechanism provided in this application is shown.
[0038] In some implementations, the limiting mechanism includes: a first boss 10, a second boss 20, a limiting seat 30, and a locking member 40.
[0039] The first boss 10 includes a first body 11 and a first protrusion 12; the second boss 20 includes a second body 21 and a second protrusion 22; the limiting seat 30 is provided with a first opening 31 and a second opening 32 at intervals along a first direction, wherein the first protrusion 12 is used to insert into the first opening 31 along a second direction, and the second protrusion 22 is used to insert into the second opening 32 along a second direction; a plurality of locking members 40 are respectively connected to the first boss 10, the second boss 20 and the limiting seat 30 along a second direction.
[0040] In this embodiment, the first boss 10 and the second boss 20 are nested with the limiting seat 30 respectively, combined with Figure 2As shown, the first protrusion 12 penetrates the first opening 31, and the second protrusion 22 penetrates the second opening 32, so that the first protrusion 10 and the second protrusion 20 are nested together with the limiting seat 30, thereby ensuring that the battery box forms a counterforce through the first protrusion 10 and the second protrusion 20 in the first direction (horizontal direction), thereby ensuring the limiting of the electric bicycle's battery box in the horizontal direction.
[0041] The locking component 40 is connected to the first boss 10, the second boss 20 and the limiting seat 30 along the second direction (vertical direction) to ensure the tight connection and limiting of each component in the vertical direction. The locking component 40 can also be connected to the external vehicle frame to ensure the stable fixation of the battery box in the vertical direction.
[0042] Furthermore, the nested structure of the first boss 10, the second boss 20, and the limiting seat 30 effectively avoids the use of welding processes, thereby simplifying subsequent installation and disassembly operations. The nested connection between the first boss 10, the second boss 20, and the limiting seat 30 effectively reduces the space occupied by the battery box, while ensuring the strength and stability of the internal components of the battery box and the connection between the battery box and the electric bicycle.
[0043] In some implementation schemes, combined Figure 3 As shown, the limiting seat 30 is also provided with a receiving chamber 33 communicating with the second opening 32, wherein the second protrusion 22 penetrates the second opening 32 along the second direction and is located in the receiving chamber 33 to further improve the connection tightness between the second protrusion 20 and the limiting seat 30, such as Figure 2 As shown, the second protrusion 22 is embedded in the limiting seat 30 to ensure further multi-directional limiting of its battery box (such as in the horizontal and vertical directions).
[0044] In some embodiments, the limiting seat 30 is further provided with a first groove 34, which is recessed into the receiving chamber 33; wherein, the second protrusion 22 is provided with a second groove 23 corresponding to the first groove 34, so that when the second protrusion 22 is located in the receiving chamber 33, the first groove 34 can be embedded in the second groove 23.
[0045] In this embodiment, the first groove 34 and the second groove 23 are fitted together to provide an additional locking structure, which further ensures that the second protrusion 22 is fixed in position within the accommodating space and prevents loosening that may be caused by vibration of the battery box.
[0046] See Figure 4 As shown, Figure 4 A bottom view of an embodiment of a limiting mechanism provided in this application is shown.
[0047] In some implementation schemes, combined Figure 4 and Figure 2As shown, the locking member 40 includes a plurality of first locking members 41 and a plurality of second locking members 42. The plurality of first locking members 41 are used to insert into the upper surface of the limiting seat 30 along the second direction, and the plurality of second locking members 42 are used to insert into the lower surface of the limiting seat 30 along the second direction, and respectively lock with the first body 11 or the second body 21.
[0048] In this embodiment, the upper part of the limiting seat 30 is connected to the first locking member 41, allowing the locking mechanism to connect with and fix the internal components of the battery box. The lower part of the limiting seat is fixed by the second locking member 42, enabling the locking mechanism to be stably connected to the electric bicycle outside the battery box. The first locking member 41 and the second locking member 42 work together to form a double lock in the second direction, ensuring the stability of the battery box and improving the convenience of subsequent maintenance. For example, combined with... Figure 2 As shown, when assembling the limiting mechanism, the first groove 34 and the second groove 23 can be fitted together by interference fit to improve the stability of the limiting seat 30 in the horizontal direction.
[0049] In some embodiments, the limiting seat 30 is further provided with a stop bar 310, which is located on the outer periphery of the first opening 31. Since the first protrusion 12 is not located within the enclosed space, adding the stop bar 310 can provide additional limiting effect for the first protrusion 10. For example Figure 3 As shown, when the height of the first protrusion 12 is too high, the opening of the limiting seat 30 is too low compared to the first protrusion 12, and its limiting effect is weak. By adding a stop bar 310, the fixing effect of the limiting seat 30 on the first protrusion 12 can be improved.
[0050] In some implementations, the first protrusion 12 is further provided with a plurality of guide strips 14 on the side facing the second protrusion 22 along a first direction. The guide strips 14 are spaced apart on both sides of the first body 11 along a third direction. The plurality of guide strips 14 are provided to facilitate the positioning and installation of the first protrusion 12.
[0051] In some embodiments, the limiting mechanism further includes a fixed bracket 50 (not shown in the figure), which is located between the first boss 10 and the second boss 20 along a first direction. The fixed bracket 50 also includes a limiting post that extends along a second direction and is connected to the first protrusion 12.
[0052] Furthermore, the first locking member 41 passes through the fixed bracket 50 along the second direction and is inserted into the upper surface of the limiting seat 30.
[0053] In this embodiment, the fixing bracket 50 is used to install and fix the main components of the battery box, such as locks and charging components. Setting it between the first boss 10 and the second boss 20 can effectively limit the fixing bracket 50, thereby further ensuring the stability of the internal components of the battery box.
[0054] Combination Figure 5 As shown, Figure 5 A partial connection structure diagram of an embodiment of a limiting mechanism provided in this application is shown.
[0055] In some embodiments, the first protrusion 12 is further provided with a locking groove 13 on the side facing the second protrusion 22 along the first direction. The locking groove 13 can engage with the locking tongue 130 located on the fixed bracket 50 to achieve mechanical locking of the battery box and prevent the battery box from being abnormally removed. Moreover, the locking groove 13 is provided on the first protrusion 12, which can effectively ensure that the battery box can be mechanically locked to the electric bicycle.
[0056] See Figure 6 As shown, Figure 6 A schematic diagram of the connection structure of an embodiment of an electric bicycle provided in this application is shown.
[0057] In some embodiments, this application also provides an electric bicycle, including the aforementioned limiting mechanism, battery box, and tube frame, wherein the limiting mechanism is located inside the battery box, the tube frame is a hollow structure, and the second locking member 42 of the limiting mechanism penetrates the upper surface of the tube frame and locks with the limiting seat 30.
[0058] In this embodiment, the aforementioned limiting mechanism effectively ensures the stability of the battery box relative to the vehicle frame in both the horizontal (front-back, left-right) and vertical directions, thereby effectively preventing internal components from loosening or falling off during use. Furthermore, the fact that the limiting mechanism is integrated into the battery box design maintains the overall aesthetics of the electric bicycle.
[0059] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the description and drawings of this utility model, or direct or indirect applications in other related technical fields, should be included within the protection scope of this utility model.
