Description

Technical Field

[0001] This invention relates to the technical field of electric bicycles, and in particular to a mounting bracket, a frame, and an electric bicycle. Background Technology

[0002] Electric bicycles consist of a frame and a battery box, with the battery box installed inside the frame. For bottom-mounted battery boxes, meaning those removed from the bottom of the frame, a safety lock and a secondary lock are typically installed. When the safety lock is opened, the secondary lock prevents the battery box from falling out, allowing for manual removal of the battery box.

[0003] Traditional secondary locks require an externally protruding operating part for unlocking. For example, in utility model patent CN202020126346, a rotating handle protrudes from the surface of the battery box. Opening the secondary lock via this exposed handle results in poor surface flatness and a less compact structure. Furthermore, removing the battery box from the frame requires first unlocking the secondary lock and then pulling it out, adding multiple steps and reducing the ease of removal. Summary of the Invention

[0004] The purpose of this invention is to overcome the shortcomings of the prior art and provide a mounting bracket, frame, and electric bicycle that makes the surface of the battery box more flat, the structure of the battery box more compact, and the removal of the battery box more convenient.

[0005] The objective of this invention is achieved through the following technical solution:

[0007] The mounting frame has a battery mounting slot formed on its lower side, which is used to accommodate a battery box.

[0008] An electrical connector, wherein the electrical connector is installed within the battery mounting slot and is used for electrical connection with the battery compartment; and

[0009] An automatic elastic latch is installed in the battery mounting slot and is used to elastically engage with the battery box to lock the battery box.

[0010] In one embodiment, the automatic resilient latch includes:

[0011] An elastic element, said elastic element being mounted within the mounting frame; and

[0012] An abutment member is connected to the elastic member, and the abutment member is at least partially located within the battery mounting slot and is used to engage with the battery box.

[0013] In one embodiment, the automatic resilient latching lock further includes a mounting member fixedly connected to the mounting frame, the mounting member forming a telescopic channel, the resilient member being located within the telescopic channel and abutting against the mounting member, and an abutting member also being located within the telescopic channel and abutting against the resilient member, so that the resilient member is used to push the abutting member to latch against the battery box; and / or

[0014] The portion of the abutment located in the battery mounting slot has an arc surface.

[0015] In one embodiment, the mounting frame has a mounting cavity that communicates with the battery mounting slot; the mounting frame also includes a base located within the mounting cavity and fixedly connected to the mounting frame, and the mounting component is fixedly connected to the base so that the mounting component is fixedly connected to the mounting frame through the base.

[0016] In one embodiment, the mounting element is embedded in the base.

[0017] A vehicle frame includes the mounting bracket described in any of the above embodiments. The vehicle frame also includes a battery box, which includes a box body and a snap-fit ​​portion. The snap-fit ​​portion is connected to the box body, and both the box body and the snap-fit ​​portion are accommodated in the battery mounting slot. An automatic elastic snap-fit ​​lock is snapped into the snap-fit ​​portion.

[0018] In one embodiment, the battery compartment further includes a snap-fit ​​spring connected to the compartment body; the mounting bracket further includes a locking tongue movably connected to the battery mounting slot; and the locking tongue is used to engage with the snap-fit ​​spring. And / or

[0019] The latching part has a latching groove, and the automatic elastic latching lock is latched into the latching groove.

[0020] In one embodiment, the snap-fit ​​spring has an abutment groove, and the locking tongue snaps into the abutment groove; and / or,

[0021] Both the snap-fit ​​spring and the snap-fit ​​part are fixedly connected to the first end of the box body. The snap-fit ​​spring is provided with a clearance notch. The clearance notch and the abutment groove are arranged sequentially along the direction of taking out the battery box.

[0022] In one embodiment, the inner wall of the snap-fit ​​groove is an arc surface.

[0023] An electric bicycle includes the frame described in any of the above embodiments.

[0024] Compared with the prior art, the present invention has at least the following advantages:

[0025] 1. After the safety lock is opened, the automatic elastic latching lock can be deformed and disengaged from the latching part of the battery box by pulling down the battery box. That is, the secondary lock is automatically opened when the battery box is pulled down. There is no need to set a protruding operating part on the outside of the battery box, which makes the surface of the battery box flatter and the structure of the battery box more compact.

[0026] 2. Once the safety lock is opened, the secondary lock automatically opens when the battery box is pulled down, meaning that the battery box can be removed with just one pull-down action, making it highly convenient to remove the battery box. Attached Figure Description

[0036] To facilitate understanding of the present invention, a more complete description will be given below with reference to the accompanying drawings. Preferred embodiments of the invention are shown in the drawings. However, the invention can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to provide a thorough and complete understanding of the disclosure of the invention.

[0037] It should be noted that when an element is referred to as being "fixed to" another element, it can be directly attached to the other element or there may be an intervening element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or there may be an intervening element. The terms "vertical," "horizontal," "left," "right," and similar expressions used herein are for illustrative purposes only and do not represent the only possible implementation.

[0038] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein in the description of the invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0039] This application provides a mounting bracket, including a mounting body, an electrical connector, and an automatic resilient latch. The mounting body has a battery mounting slot formed on its lower side for accommodating a battery compartment. The electrical connector is installed within the battery mounting slot and is used for electrical connection with the battery compartment. The automatic resilient latch is installed within the battery mounting slot and is used for resiliently engaging with the battery compartment to lock it in place.

[0040] This application also provides a frame, including the aforementioned mounting bracket and a battery box. The battery box includes a box body and a snap-fit ​​portion, the snap-fit ​​portion being connected to the box body. Both the box body and the snap-fit ​​portion are accommodated within a battery mounting slot, and an automatic elastic snap-fit ​​lock is engaged with the snap-fit ​​portion. This application also provides an electric bicycle, including the aforementioned frame.

[0041] The aforementioned mounting bracket, frame, and electric bicycle, once the safety lock is opened, allow the automatic elastic locking mechanism to deform and disengage from the battery box's locking portion by pulling it downwards. This means the secondary lock automatically opens when the battery box is pulled down, eliminating the need for protruding operating parts on the outside of the battery box. This results in a higher degree of surface flatness and structural compactness for the battery box. The automatic opening of the secondary lock when the safety lock is open and the battery box is pulled down allows for easy removal of the battery box with just one pull, significantly enhancing convenience.

[0042] To better understand the technical solution and beneficial effects of this application, the following detailed description is provided in conjunction with specific embodiments:

[0043] like Figure 1 As shown, in one embodiment, the vehicle frame 10 includes a mounting bracket 100 and a battery box 200, with the battery box 200 mounted inside the mounting bracket 100.

[0044] like Figures 2 to 4 As shown, in one embodiment, the mounting bracket 100 includes a mounting body 110, an electrical connector 120, and an automatic resilient latching lock 130. A battery mounting groove 1101 is formed on the lower side of the mounting body 110, which accommodates a battery case 200, making the battery case 200 a bottom-mounted type. The electrical connector 120 is installed in the battery mounting groove 1101 and is used for electrical connection with the battery case 200. The automatic resilient latching lock 130 is installed in the battery mounting groove 1101 and is used for resilient engagement with the latching portion 210 of the battery case 200, thereby locking the battery case 200. Furthermore, the mounting bracket 100 also includes a safety lock 140, which includes a lock cylinder and a bolt 141. The lock cylinder is installed inside the mounting bracket 110, and the bolt 141 is connected to the power output end of the lock cylinder. The bolt 141 is used to engage with the battery box 200. The bolt 141 is engaged with the battery box 200 by controlling the lock cylinder.

[0045] like Figure 4 and Figure 5 As shown, in this embodiment, the automatic elastic latching lock 130 is a secondary lock, that is, the automatic elastic latching lock 130 is used to prevent the battery box 200 from falling off after the safety lock 140 is opened. When the safety lock 140 is opened, that is, when the lock cylinder drives the bolt 141 to separate from the battery box 200, the battery box 200 will not fall off the mounting bracket 110 because the automatic elastic latching lock 130 is used to elastically engage with the latching part 210 of the battery box 200. At this time, pulling down the battery box 200 can cause the battery box 200 to push the automatic elastic latching lock 130 to deform and leave the latching part 210 of the battery box 200. That is, the secondary lock is automatically opened when the battery box 200 is pulled down. As the battery box 200 continues to be pulled down, the battery box 200 will be completely removed from the mounting bracket 110, thus realizing the operation of removing the battery box 200 from the mounting bracket 100.

[0046] like Figure 4 and Figure 5As shown, when the battery box 200 is inserted into the battery mounting slot 1101, the battery box 200 will push the automatic elastic locking 130 to deform, so as to prevent the automatic elastic locking 130 from obstructing the battery box 200 from being inserted into the battery mounting slot 1101. After the battery box 200 is fully inserted into the battery mounting slot 1101, the automatic elastic locking 130 will elastically return to its original position, so that the automatic elastic locking 130 extends into the battery mounting slot 1101, and then the automatic elastic locking 130 engages with the locking part 210 of the battery box 200.

[0047] The aforementioned frame 10 and mounting bracket 100, when the safety lock 140 is opened, allow the automatic elastic locking 130 to deform and disengage from the locking part 210 of the battery box 200 by pulling down the battery box 200. This automatically unlocks the secondary lock when the battery box 200 is pulled down, eliminating the need for a protruding operating part on the outside of the battery box 200, resulting in a higher surface flatness and a more compact structure. The automatic unlocking of the secondary lock when the safety lock 140 is opened and the battery box 200 is pulled down allows for easy removal of the battery box 200 with just one pull, significantly improving convenience.

[0048] like Figure 6 and Figure 7 As shown, in one embodiment, the automatic resilient latching lock 130 includes a resilient element 131 and an abutment element 132. The resilient element 131 is installed inside the mounting frame 110, and the abutment element 132 is connected to the resilient element 131. The abutment element 132 is at least partially located inside the battery mounting slot 1101 and is used to latch with the battery box 200. In this embodiment, during the process of inserting or removing the battery box 200 from the battery mounting slot 1101, the latching portion 210 of the battery box 200 abuts against the abutment element 132, causing the abutment element 132 to compress the resilient element 131, thereby causing the abutment element 132 to leave the insertion / removal path of the battery box 200, thus automatically completing the unlocking action of the secondary lock to ensure that the battery box 200 is smoothly inserted into the battery mounting slot 1101. When the battery box 200 is fully inserted into the battery mounting slot 1101, the elastic member 131 pushes the abutment member 132 to engage with the locking part 210 of the battery box 200, so that the locking part 210 automatically locks the battery box 200, thus automatically completing the locking action of the secondary lock.

[0049] like Figure 6 and Figure 7As shown, in one embodiment, the automatic elastic latching lock 130 further includes a mounting member 133, which is fixedly connected to the mounting frame 110. The mounting member 133 forms a telescopic channel 1331. The elastic member 131 is located within the telescopic channel 1331 and abuts against the mounting member 133. An abutting member 132 is also located within the telescopic channel 1331 and abuts against the elastic member 131, so that the elastic member 131 pushes the abutting member 132 to latch onto the battery box 200. In this embodiment, the mounting member 133 is fixedly connected inside the mounting frame 110, the elastic member 131 is completely housed within the telescopic channel 1331, and a portion of the abutting member 132 is located within the telescopic channel 1331. The elastic member 131 abuts against both the mounting member 133 and the abutting member 132, so that the elastic member 131 provides the abutting force for the abutting member 132. Since the elastic member 131 and the abutment member 132 are partially housed within the telescopic channel 1331, the positional stability of the elastic member 131 and the abutment member 132 is improved.

[0050] like Figure 4 As shown, in one embodiment, the mounting frame 110 has a mounting cavity 1102, which communicates with the battery mounting slot 1101. Further, the mounting frame 100 also includes a base 150, which is located within the mounting cavity 1102 and fixedly connected to the mounting frame 110. A mounting member 133 is fixedly connected to the base 150, so that the mounting member 133 is fixedly connected to the mounting frame 110 via the base 150.

[0051] like Figure 7 As shown, in one embodiment, the mounting member 133 is embedded in the base 150 so that the mounting member 133 is fixedly connected to the base 150.

[0052] like Figure 7 As shown, in one embodiment, the mounting member 133 includes a mounting sleeve 133a and a limiting portion 133b. Both the mounting sleeve 133a and the limiting portion 133b are embedded in the base 150. A telescopic channel 1331 is formed in the mounting sleeve 133a, and the limiting portion 133b protrudes from the outer side of the mounting sleeve 133a, so that the limiting portion 133b and the mounting sleeve 133a form a stepped structure. In this embodiment, when the abutting member 132 is subjected to the abutting force of the snap-fit ​​portion 210 of the battery box 200, the abutting member 132 pushes the elastic member 131 to compress, thereby causing the mounting member 133 to be subjected to the abutting force of the elastic member 131. The limiting portion 133b and the mounting sleeve 133a are both embedded in the base 150, so that the limiting member restricts the movement of the mounting member 133, preventing the mounting member 133 from detaching from the base 150.

[0053] like Figure 7As shown, in one embodiment, the portion of the abutment 132 located in the battery mounting slot 1101 is an arc surface, so that the portion of the abutment 132 that abuts against the battery box 200 is an arc surface. In this embodiment, when the latching portion 210 of the battery box 200 abuts against the abutment 132, since the portion of the abutment 132 that abuts against the latching portion 210 of the battery box 200 is an arc surface, the force exerted by the latching portion 210 of the battery box 200 on the abutment 132 can push the abutment 132 to compress the elastic member 131, thereby causing the abutment 132 to leave the path of inserting or removing the battery box 200 from the battery mounting slot 1101.

[0054] like Figure 7 As shown, in one embodiment, the elastic element 131 is a spring structure to make it elastic. Of course, in other embodiments, the elastic element 131 can also be a silicone structure, a rubber structure, or other existing elastic structures.

[0055] like Figure 7 As shown, in one embodiment, the abutment 132 is spherical so that the latching portion 210 of the battery box 200 can better push the abutment 132 to move.

[0056] like Figure 7 As shown, in one embodiment, the opening of the telescopic channel 1331 is smaller than the diameter of the abutment 132 to prevent the abutment 132 from completely leaving the telescopic channel 1331, thereby preventing the abutment 132 from separating from the mounting member 133 and the elastic member 131, and thus preventing the automatic elastic locking 130 from failing.

[0057] It is understandable that when the elastic member 131 pushes the abutment 132 into the battery mounting slot 1101, the abutment 132 will impact the opening of the mounting member 133. As the number of impacts of the abutment 132 increases, the abutment 132 will become smaller due to wear, while the opening of the telescopic channel 1331 will become larger, making it easier for the abutment 132 to completely detach from the telescopic channel 1331. Consequently, the abutment 132 will be easier to separate from the elastic member 131, thus causing the automatic elastic locking 130 to fail, and even the secondary lock to fail. Moreover, when the elastic member 131 pushes the abutment 132 to abut against the locking part 210 of the battery box 200, the abutment 132 will also impact the locking part 210, making the locking part 210 of the battery box 200 more prone to wear, thus making the locking effect of the automatic elastic locking 130 poor, and even the locking effect of the secondary lock poor.

[0058] To reduce wear on the elastic element 131 and the mounting element 133, and thus improve the service life of the automatic elastic locking 130, such as... Figure 8As shown, in one embodiment, the automatic resilient latching lock 130 further includes a resilient washer 134. The resilient washer 134 is located within the telescopic channel 1331 and is fixedly connected to the opening of the mounting member 133. When the abutment member 132 engages with the latching portion 210 of the battery box 200, the abutment member 132 also abuts against the resilient washer 134. In this embodiment, when the resilient member 131 pushes the abutment member 132 into the battery mounting slot 1101, the abutment member 132 will impact the resilient washer 134. Since the resilient washer 134 is elastic, it alleviates the impact force of the abutment member 132, preventing the abutment member 132 from impacting the opening of the mounting member 133. This suppresses wear on the abutment member 132 and the opening of the mounting member 133, preventing the abutment member 132 from disengaging from the telescopic channel 1331 after multiple uses and improving the service life of the automatic resilient latching lock 130. Furthermore, since the elastic washer 134 mitigates the impact of the abutment member 132, the impact of the abutment member 132 on the latching portion 210 of the battery box 200 is reduced, inhibiting the wear of the abutment member 132 on the latching portion 210 of the battery box 200, resulting in a better locking effect of the automatic elastic latching lock 130. Further, the mounting member 133 forms an embedding groove on the inner wall of the telescopic channel 1331, and the elastic washer 134 is embedded in the embedding groove. It can be understood that the elastic washer 134 can be a silicone structure, a rubber structure, or other flexible structure.

[0059] like Figure 8 As shown, in one embodiment, the base 150 has a threaded hole 151, and the mounting member 133 is threaded into the threaded hole 151, making the mounting member 133 detachably connected to the base 150. In this embodiment, when the automatic resilient latch 130 needs to be replaced or maintained, the mounting member 133 is unscrewed from the threaded hole 151, improving the convenience of replacing and maintaining the automatic resilient latch 130.

[0060] like Figure 8 As shown, further, an annular limiting groove 1332 is formed on the side of the limiting portion 133b adjacent to the battery mounting groove 1101. In this embodiment, the annular limiting groove 1332 is used to accommodate an auxiliary tool for tightening the mounting member 133. When disassembling the mounting member 133, one end of the auxiliary tool is inserted into the annular limiting groove 1332, and then the auxiliary tool is tightened to unscrew the mounting member 133 out of the threaded hole 151. Since the annular limiting groove 1332 is adapted to the auxiliary tool for disassembling the mounting member 133, the convenience of disassembling the mounting member 133 is improved.

[0061] like Figure 5 As shown, in one embodiment, the battery box 200 includes a box body 220 and a snap-fit ​​part 210. The snap-fit ​​part 210 is connected to the box body 220. Both the box body 220 and the snap-fit ​​part 210 are accommodated in the battery mounting slot 1101. An automatic elastic snap-fit ​​lock 130 is snapped into the snap-fit ​​part 210.

[0062] In the aforementioned frame 10, after the safety lock 140 is opened, pulling down the battery box 200 causes the automatic elastic locking 130 to deform and disengage from the locking part 210 of the battery box 200. This means the secondary lock automatically opens when the battery box 200 is pulled down, eliminating the need for a protruding operating part on the outside of the battery box 200. This results in a higher surface flatness and a more compact structure for the battery box 200. The automatic opening of the secondary lock when the safety lock 140 is opened and the battery box 200 is pulled down allows for easy removal of the battery box 200 with just one pull, significantly improving convenience.

[0063] like Figure 5 As shown, in one embodiment, the battery box 200 further includes a snap-fit ​​spring clip 230 connected to the box body 220. The mounting bracket 100 also includes a locking tongue 141 movably connected within the battery mounting slot 1101, and the locking tongue 141 is used to engage with the snap-fit ​​spring clip 230. In this embodiment, the snap-fit ​​spring clip 230 is a metal structural component with high wear resistance. The engagement of the locking tongue 141 with the snap-fit ​​spring clip 230 prevents the locking tongue 141 from contacting the box body 220, thereby preventing the locking tongue 141 from wearing down the box body 220 and improving the service life of the box body 220.

[0064] like Figure 5 As shown, in one embodiment, the snap-fit ​​spring 230 is formed with an abutment groove 231, and the locking tongue 141 is snapped into the abutment groove 231 so that the locking tongue 141 is snapped into the snap-fit ​​spring 230.

[0065] like Figure 5 As shown, in one embodiment, the snap-fit ​​spring 230 is provided with a clearance notch 232, and the clearance notch 232 and the abutment groove 231 are arranged sequentially along the direction of removing the battery box 200. In this embodiment, the snap-fit ​​spring 230 and the snap-fit ​​part 210 are both fixedly connected to the first end of the box body 220. The clearance notch 232 and the abutment groove 231 are arranged sequentially along the direction of removing the battery box 200, so that the clearance notch 232 is formed on the upper side of the first end of the box body 220. After the safety lock 140 is opened, the first end of the box body 220 is moved down so that the snap-fit ​​part 210 separates from the automatic elastic snap-fit ​​lock 130. As the box body 220 continues to move down, the first end and the second end of the battery box 200 leave the battery mounting groove 1101 in sequence. During the process of removing the battery box 200, since the clearance notch 232 is formed on the upper side of the box body 220, the snap-fit ​​spring 230 is prevented from interfering with the removal of the battery box 200, thus improving the smoothness of removing the battery box 200.

[0066] like Figure 5As shown, in one embodiment, the latching portion 210 has a latching groove 211, and the automatic elastic latching lock 130 latches into the latching groove 211 so that the automatic elastic latching lock 130 latches into the latching portion 210. Of course, in another embodiment, the latching portion 210 may also be a protruding structure.

[0067] like Figure 5 As shown, in one embodiment, the inner wall of the snap-fit ​​groove 211 is an arc surface. In this embodiment, when the inner wall of the snap-fit ​​groove 211 abuts against the abutment member 132, because the inner wall of the snap-fit ​​groove 211 is an arc surface, the snap-fit ​​portion 210 can more easily push the abutment member 132 to compress the elastic member 131, thereby making it easier for the abutment member 132 to leave the path of the battery box 200 being inserted into or removed from the battery mounting slot 1101, thus improving the smoothness of the battery box 200 being inserted into or removed from the battery mounting slot 1101.

[0068] In another embodiment, the automatic resilient latch 130 is made of silicone. Further, the mounting frame 110 has a mounting cavity 1102, which communicates with the battery mounting slot 1101. The mounting frame 100 also includes a base 150, which is located within the mounting cavity 1102 and fixedly connected to the mounting frame 110, with the automatic resilient latch 130 embedded in the base 150. Further, the portion of the automatic resilient latch 130 protruding from the base 150 is arc-shaped.

[0069] In another embodiment, the automatic resilient latch 130 is a rubber structure. Further, the mounting frame 110 has a mounting cavity 1102, which communicates with the battery mounting slot 1101. The mounting frame 100 also includes a base 150, which is located within the mounting cavity 1102 and fixedly connected to the mounting frame 110, with the automatic resilient latch 130 embedded in the base 150. Further, the portion of the automatic resilient latch 130 protruding from the base 150 is arc-shaped.

[0070] This application also provides an electric bicycle, including the frame 10 described in any of the above embodiments.

[0071] In the aforementioned electric bicycle, after the safety lock 140 is opened, pulling down the battery box 200 causes the automatic elastic locking 130 to deform and disengage from the locking part 210 of the battery box 200. This means the secondary lock automatically opens when the battery box 200 is pulled down, eliminating the need for a protruding operating part on the outside of the battery box 200. This results in a higher surface flatness and a more compact structure for the battery box 200. The automatic opening of the secondary lock after the safety lock 140 is opened, requiring only a single pull down action, makes removing the battery box 200 highly convenient.

[0072] Compared with the prior art, the present invention has at least the following advantages:

[0073] 1.
