Description

Technical Field

[0001] The present disclosure relates to the technical field of electric bicycles, and in particular to a battery module and a frame structure. Background Art

[0002] With the development of the new energy industry, the use of electric bicycles is becoming more and more popular, and the installation and removal of batteries is an important part of electric bicycle maintenance.

[0003] Generally, there is a mounting hole on the lower side of the frame, and the battery is placed inside the frame through the mounting hole and fixed inside the frame by a mechanical lock. The mechanical lock is controlled by a key. When unlocking the mechanical lock, the user opens the mechanical lock with one hand and places the other hand on the lower side of the battery to catch the dropped battery, so as to avoid the problem of the battery falling when unlocking. However, if the user forgets to catch the battery with his hand, the battery will accidentally fall, causing the battery to injure the user or damage the battery.

[0004] In order to avoid the problem of accidental battery falling, the related art adds a secondary lock. When the mechanical lock is unlocked, the spring ejects part of the battery, causing one end of the battery to rotate downward a certain distance. At this time, part of one end of the battery protrudes from the frame, and the secondary lock locks the battery. Then, one hand turns the secondary lock to open the secondary lock, and the other hand pulls the battery downward to remove the battery, such as CN214648755U-A battery box assembly with a floating cover. However, since one hand unlocks the secondary lock and the other hand pulls the battery, it requires two hands to operate at the same time to remove the battery, resulting in poor convenience in removing the battery.

[0005] In order to improve the convenience of removing the battery, the related technology also provides a more convenient battery. A pressing part is set at the end of the secondary lock. After the mechanical lock is opened, the spring pops out part of one end of the battery, so that the pressing part of the secondary lock protrudes from the frame. At this time, the secondary lock locks the battery. When removing the battery, press the pressing part of the secondary lock with one hand and pull the end of the battery downward to remove the battery. In this way, the battery can be removed with one hand.

[0006] However, in order to improve the convenience of moving the battery, a handle needs to be protruded from the outside of the battery. After the battery is installed in the frame, the handle protrudes from the outside of the frame, resulting in poor compactness of the frame structure, causing the structural compactness of the electric bicycle to urgently need to be improved. Utility Model Content

[0007] The purpose of the present invention is to overcome the deficiencies in the prior art and provide a battery module and a frame structure with a higher compactness.

[0008] The purpose of this disclosure is achieved through the following technical solutions:

[0012] A handle is rotatably connected to the first end of the battery assembly and is used to be arranged between the first end of the battery assembly and the frame. The handle also abuts against a side of the elastic secondary lock facing away from the battery assembly. The handle protrudes from the outside of the frame when the elastic secondary lock is in a locked state, and pushes the elastic secondary lock to unlock when rotating toward the direction of the battery assembly.

[0013] In some embodiments, the battery module also includes a rotating shaft, a mounting groove is formed on the first end face of the battery assembly, the mounting groove extends to the outside of the battery assembly, the rotating shaft is located in the mounting groove and is fixedly connected to the battery assembly, one end of the handle is located in the mounting groove and is rotatably sleeved on the rotating shaft, so that the handle is rotatably connected to the first end of the battery assembly through the rotating shaft.

[0014] In some embodiments, there are two mounting grooves and two rotating shafts, and the two mounting grooves extend to opposite sides of the battery assembly respectively. Both ends of the handle are arranged in the two mounting grooves one by one and are rotatably sleeved on the two rotating shafts one by one.

[0015] In some embodiments, the elastic secondary lock includes a locking spring, a first end of which is connected to a first end of the battery assembly, and the locking spring is used to engage with the frame after the mechanical lock is unlocked;

[0016] The handle piece abuts against a side of the second end of the locking spring sheet away from the battery assembly. The handle piece protrudes from the outside of the frame when the locking spring sheet is in a locked state, and pushes the locking spring sheet to unlock when rotating toward the battery assembly.

[0017] In some embodiments, the locking spring is bent to form a snap-on protrusion, the snap-on protrusion is located between the two ends of the locking spring, the snap-on protrusion is toward the side of the locking spring away from the battery assembly, and the snap-on protrusion is used to snap-on with the frame after the mechanical lock is unlocked.

[0018] In some embodiments, a limiting groove is formed on one side of the snap-fitting protrusion adjacent to the battery assembly, and a limiting portion is protruded from the first end of the battery assembly, and the limiting portion is disposed in the limiting groove.

[0019] In some embodiments, the elastic secondary lock further includes an elastic pusher, and the elastic pusher is respectively in contact with the second end of the locking spring and the first end of the battery assembly.

[0020] In some embodiments, a first end surface of the battery assembly is provided with a receiving groove, and the second end of the locking spring is located in the receiving groove.

[0021] In some embodiments, an anti-skid protrusion is provided on a side of the handle member facing away from the battery assembly, and the anti-skid protrusion is located on the outer side of the frame when the elastic secondary lock is in a locked state.

[0022] A vehicle frame structure includes the battery module described in any of the above embodiments, and the frame structure also includes a frame, the frame is provided with a receiving groove, and the battery module is arranged in the receiving groove.

When disassembling the battery module, the user holds the first end of the battery module with one hand, and at the same time, presses the handle with the fingers of the hand in the direction of the battery assembly, specifically, presses the part of the handle protruding from the outside of the frame, so that the handle pushes the elastic secondary lock to unlock, and then pulls the battery module in the direction of separating from the frame, so that the battery module is completely separated from the frame, so as to achieve the effect of disassembling the battery module. In this way, the battery module can be disassembled with one hand, which improves the convenience of disassembling the battery module and the efficiency of disassembling the battery module.

[0025] 2. Since the handle is arranged between the first end of the battery assembly and the frame, after the battery module is installed on the frame, the handle is hidden inside the frame, that is, the handle will not be exposed on the outside of the frame, thereby improving the compactness of the frame structure and further improving the structural compactness of the electric bicycle.

[0026] 3. Since the handle does not protrude from the outside of the frame after the battery module is installed on the frame, the surface flatness of the electric bicycle is improved, the probability of the electric bicycle accidentally hitting the user is reduced, and the safety performance of the electric bicycle is improved.

The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0043] In order to better understand the technical solutions and beneficial effects of the present invention, the present invention is further described in detail below in conjunction with specific embodiments:

[0044] like Figures 1 to 3 As shown, the frame structure of an embodiment includes a battery module 10 and a frame 20, wherein the frame 20 is provided with a receiving groove, and the battery module 10 is arranged in the receiving groove. Further, the frame 20 includes a frame body 500, a mechanical lock 600 and a clamping member 700, wherein the frame body 500 is provided with a receiving groove, the mechanical lock 600 is installed on the frame body 500 and is arranged corresponding to the first end of the receiving groove, the mechanical lock 600 is used to connect with the first end of the battery module 10, the clamping member 700 is connected to the frame body 500 and is arranged corresponding to the first end of the receiving groove, the clamping member 700 is used to clamp with the first end of the battery module 10, the mechanical lock 600 and the clamping member 700 are arranged in sequence along the disassembly direction of the battery module 10, and when the mechanical lock 600 is opened, the clamping member 700 is clamped with the first end of the battery module 10.

[0045] Please refer to Figures 2 to 4 In some embodiments, the battery module 10 includes a battery assembly 100, an elastic secondary lock 200, and a handle 300. The elastic secondary lock 200 is connected to the first end of the battery assembly 100, and is used to engage with the engaging member 700 of the frame 20 after the mechanical lock 600 is unlocked. That is, after the mechanical lock 600 is unlocked by a key, part of the battery module 10 pops out of the frame 20, so that the elastic secondary lock 200 engages with the frame 20, that is, the elastic secondary lock 200 is in a locked state, so as to lock the battery assembly 100 in the frame 20.

[0046] like Figure 2As shown, the handle 300 is rotatably connected to the first end of the battery assembly 100 . When moving the battery module 10 , the user carries the handle 300 , which improves the convenience of moving the battery assembly 100 .

[0047] like Figure 3 and Figure 4 As shown, the handle 300 is used to be arranged between the first end of the battery assembly 100 and the frame 20, so that the handle 300 is hidden between the first end of the battery assembly 100 and the frame 20, that is, the handle 300 is hidden inside the frame structure. Specifically, the handle 300 is completely located in the space formed by the first end surface of the battery assembly 100 and the frame 20. The handle 300 also abuts against the side of the elastic secondary lock 200 that is away from the battery assembly 100.

[0048] like Figure 5 and Figure 6 As shown, the handle member 300 protrudes from the outside of the frame 20 when the elastic secondary lock 200 is in a locked state, and pushes the elastic secondary lock 200 to unlock when rotating in the direction of the battery assembly 100, that is, the handle member 300 protrudes from the outside of the frame 20 when the elastic secondary lock 200 is engaged with the frame 20, and pushes the elastic secondary lock 200 to separate from the engaging member 700 of the frame 20 when rotating in the direction of the battery assembly 100.

[0049] like Figure 4 and Figure 5 As shown, in this embodiment, after the mechanical lock 600 is opened by the key, that is, after the mechanical lock 600 is separated from the lock groove on the first end surface of the battery assembly 100, the ejection member 800 inside the frame 20 ejects part of the battery module 10, so that the elastic secondary lock 200 is engaged with the clamping member 700 inside the frame 20, and then the elastic secondary lock 200 blocks the battery module 10 from continuing to eject, thereby locking the battery module 10, that is, achieving the effect of secondary locking. At this time, the handle member 300 and the battery assembly 100 protrude from the outside of the frame 20, that is, part of the handle member 300 and part of the battery assembly 100 are located at When the battery module 10 needs to be removed from the outside of the frame 20, the user holds the first end of the battery module 10 with one hand, and at the same time, the fingers of the hand press the handle 300 in the direction of the battery assembly 100, specifically, press the portion of the handle 300 protruding from the outside of the frame 20, so that the handle 300 pushes the elastic secondary lock 200 to deform, thereby separating the elastic secondary lock 200 from the clamping member 700 in the frame 20, that is, unlocking the elastic secondary lock 200, and then the hand pulls the battery module 10 in the direction of separating from the frame 20, so that the battery module 10 is completely separated from the frame 20, so as to achieve the effect of removing the battery module 10.

[0050] With regard to the above-mentioned frame structure and battery module 10, when disassembling the battery module 10, the user holds the first end of the battery module 10 with one hand, and at the same time, the fingers of the hand press the handle 300 in the direction of the battery assembly 100, specifically, press the portion of the handle 300 protruding from the outside of the frame 20, so that the handle 300 pushes the elastic secondary lock 200 to unlock, and then the hand pulls the battery module 10 in the direction of separating from the frame 20, so that the battery module 10 is completely separated from the frame 20, so as to achieve the effect of disassembling the battery module 10. In this way, the disassembly of the battery module 10 can be completed with one hand, which improves the convenience of disassembling the battery module 10 and the efficiency of disassembling the battery module 10.

[0051] Furthermore, since the handle 300 is disposed between the first end of the battery assembly 100 and the frame 20, after the battery module 10 is installed on the frame 20, the handle 300 is hidden inside the frame 20, that is, the handle 300 will not be exposed outside the frame 20, thereby improving the compactness of the frame structure, and further improving the structural compactness of the electric bicycle. In addition, since the handle 300 will not protrude outside the frame 20 after the battery module 10 is installed on the frame 20, the surface flatness of the electric bicycle is improved, the probability of the electric bicycle accidentally hitting the user is reduced, and the safety performance of the electric bicycle is improved.

[0052] like Figure 2 As shown, in some embodiments, the battery module 10 further includes a rotating shaft, a mounting groove 101 is provided on the first end surface of the battery assembly 100, the mounting groove 101 extends to the outside of the battery assembly 100, the rotating shaft is located in the mounting groove 101 and is fixedly connected to the battery assembly 100, one end of the handle 300 is located in the mounting groove 101, and is rotatably sleeved on the rotating shaft, so that the handle 300 can rotate around the rotating shaft, and then the handle 300 is rotatably connected to the first end of the battery assembly 100 through the rotating shaft. In addition, one end of the battery assembly 100 is located in the mounting groove 101, so that one end of the battery assembly 100 is embedded in the battery assembly 100, which improves the compactness of the battery assembly 100 and improves the surface flatness of the battery assembly 100.

[0053] like Figure 2As shown, further, the number of the mounting grooves 101 and the number of the rotating shafts are both two, and the two mounting grooves 101 extend to opposite sides of the battery assembly 100 respectively, and the two ends of the handle member 300 are arranged in the two mounting grooves 101 in a one-to-one correspondence, and are rotatably sleeved on the two rotating shafts in a one-to-one correspondence, so that the handle member 300 has two rotating connection points, which improves the connection stability between the handle member 300 and the battery assembly 100. In addition, the two ends of the handle member 300 are respectively arranged in the two mounting grooves 101, so that the two ends of the handle member 300 are embedded in the battery assembly 100, which improves the compactness of the battery assembly 100 and the surface flatness of the battery assembly 100.

[0054] Please take a photo Figure 6 and Figure 7 In one embodiment, the elastic secondary lock 200 includes a locking spring 210, a first end of which is connected to a first end of the battery assembly 100, and the locking spring 210 is used to be engaged with a clamping member 700 of the frame 20 after the mechanical lock 600 is unlocked. The handle 300 abuts against a side of the second end of the locking spring 210 that is away from the battery assembly 100, and the handle 300 protrudes from the outside of the frame 20 when the locking spring 210 is in a locked state, and pushes the locking spring 210 to unlock when rotating toward the battery assembly 100.

[0055] Please take a photo Figure 6 and Figure 7 In the present embodiment, after the mechanical lock 600 is unlocked, that is, after the mechanical lock 600 is separated from the lock groove 2101 on the first end surface of the battery assembly 100, the elastic member 800 in the frame 20 pops out of the battery module 10, and the locking spring 210 is engaged with the clamping member 700 in the frame 20, so that the locking spring 210 locks the battery assembly 100 in the frame 20. At this time, the handle 300 protrudes out of the outside of the frame 20, that is, part of the handle 300 is located on the outside of the frame 20. The user holds the first end of the battery module 10 with one hand and presses the handle 300 with the fingers of the hand at the same time, so that the handle 300 pushes the locking spring 210 to deform and separate from the clamping member 700 in the frame 20, so that the locking spring 210 is unlocked. Since the locking spring sheet 210 is deformable, the locking spring sheet 210 can be deformed by pressing the handle 300 , thereby causing the locking spring sheet 210 to leave the locking position, thereby achieving an unlocking operation of the locking spring sheet 210 .

[0056] Please take a photo Figure 6 and Figure 7Further, the locking spring sheet 210 is bent to form a clamping protrusion 211, which is located between the two ends of the locking spring sheet 210, and the clamping protrusion 211 faces the side of the locking spring sheet 210 away from the battery assembly 100. The clamping protrusion 211 is used to clamp with the clamping member 700 of the frame 20 after the mechanical lock 600 is unlocked. Specifically, the clamping protrusion 211 is used to clamp with the inner wall of the clamping groove 701 of the clamping member 700 in the frame 20, so that the clamping protrusion 211 can be clamped with the frame 20 after the mechanical lock 600 is unlocked, that is, the clamping protrusion 211 can lock the battery assembly 100 after the mechanical lock 600 is unlocked. In this embodiment, after the mechanical lock 600 is unlocked, the elastic member 800 of the frame 20 pushes the battery module 10 to pop out, so that the snap-in protrusion 211 is snapped into the snap-in groove 701 of the snap-in member 700 in the frame 20, that is, the snap-in protrusion 211 abuts against the inner wall of the snap-in groove 701, so that the inner wall of the snap-in groove 701 blocks the snap-in protrusion 211 from continuing to pop out of the frame 20, and then the inner wall of the snap-in groove 701 blocks the battery module 10 from continuing to pop out of the frame 20, so that the locking spring piece 210 has a secondary locking effect, thereby avoiding the problem of the battery module 10 accidentally falling off after the mechanical lock 600 is opened.

[0057] like Figure 7 As shown, in some embodiments, a limiting groove 2111 is formed on one side of the battery assembly 100 adjacent to the snap-in protrusion 211, and a limiting portion 110 is protruded from the first end of the battery assembly 100. The limiting portion 110 is arranged in the limiting groove 2111, so that the limiting portion 110 limits the locking spring 210, thereby preventing the locking spring 210 from deviating from the predetermined position and ensuring the normal operation of the locking spring 210.

[0058] Of course, the engaging protrusion 211 is not limited to facing the side of the locking spring sheet 210 away from the battery assembly 100. For example, in other embodiments, the engaging protrusion 211 faces the battery assembly 100, so that the engaging protrusion 211 forms a locking groove on the side away from the battery assembly 100, and the locking groove is used for the engaging member 700 in the frame 20 to engage. In this embodiment, after the mechanical lock 600 is unlocked, the elastic member 800 in the frame 20 pops out the battery module 10, so that the engaging member 700 in the frame 20 is engaged in the locking groove, that is, the inner wall of the locking groove abuts against the engaging member 700 in the frame 20, blocking the battery module 10 from continuing to pop out of the frame 20, so as to achieve the effect of secondary locking, thereby preventing the battery module 10 from accidentally falling after the mechanical lock 600 is opened.

[0059] like Figure 6 and Figure 7As shown, in some embodiments, the elastic secondary lock 200 also includes an elastic pusher 220, which respectively abuts against the second end of the locking spring 210 and the first end of the battery assembly 100, and the elastic pusher 220 is used to push the second end of the locking spring 210 to move away from the battery assembly 100. In the present embodiment, after the mechanical lock 600 is opened, the handle 300 and the locking spring 210 are partially located on the outside of the frame 20, so that the handle 300 has space to rotate away from the battery assembly 100, thereby preventing the handle 300 from blocking the locking spring 210 from deforming. At this time, the elastic pusher 220 elastically recovers and pushes the second end of the locking spring 210 to move away from the battery assembly 100, so that the locking spring 210 enters the locked position, so that the locking spring 210 is engaged with the clamping member 700 in the frame 20 to achieve the effect of secondary locking. At the same time, the second end of the locking spring 210 pushes the handle 300 to rotate away from the battery assembly 100.

[0060] It can be understood that the elastic pusher 220 can be a spring, a silicone member, a rubber member or other existing elastic structures. The elastic pusher 220 is in a compressed state after the mechanical lock 600 is opened. When the handle member 300 does not block the deformation of the locking spring sheet 210, the elastic pusher 220 elastically resets, i.e., stretches, so that the elastic pusher 220 pushes the second end of the locking spring sheet 210 to move away from the battery assembly 100.

[0061] It should be noted that, in some embodiments, after the mechanical lock 600 is opened, the elastic secondary lock 200 can enter the locked position without moving or deforming.

[0062] like Figure 6 As shown, in some embodiments, a side of the handle 300 facing away from the battery assembly 100 is provided with an anti-skid protrusion 310, and the anti-skid protrusion 310 is located on the outside of the frame 20 when the elastic secondary lock 200 is in the locked state. In this embodiment, when the user presses the handle 300, the anti-skid protrusion 310 comes into contact with the anti-skid protrusion 310, which increases the friction between the user and the handle 300 and prevents the handle 300 from slipping when the handle 300 is pressed.

[0063] like Figure 6 As shown, in some embodiments, a receiving groove 102 is formed on the first end surface of the battery assembly 100, and the second end of the locking spring 210 is located in the receiving groove 102. Since the second end of the locking spring 210 is located in the receiving groove 102, the second end of the locking spring 210 is embedded in the second end of the battery assembly 100, thereby improving the compactness of the battery module 10, thereby improving the compactness of the frame structure, and thereby improving the compactness of the battery bicycle.

[0064] like Figure 6As shown, further, a pushing protrusion 320 is protruded from one side of the handle 300 adjacent to the battery assembly 100 , and the pushing protrusion 320 abuts against a side of the elastic secondary lock 200 facing away from the battery assembly 100 .

[0065] like Figure 6 As shown, in this embodiment, since the pushing protrusion 320 protrudes from the side of the handle 300 adjacent to the battery assembly 100, the pushing protrusion 320 can enter the receiving groove 102 to push the second end of the locking spring 210, so that the deformation space of the locking spring 210 is larger. Therefore, even if the distance between the clamping member 700 in the frame 20 and the battery assembly 100 is small, the handle 300 can push the locking spring 210 to leave the clamping position. Since the distance between the clamping member 700 in the frame 20 and the battery assembly 100 can be designed to be small, the structural compactness of the frame structure is improved.

[0066] like Figure 7 As shown, further, the second end of the locking spring sheet 210 is bent to form an anti-slip portion 212, and the anti-slip portion 212 is located in the receiving groove 102 and abuts against the inner peripheral wall of the receiving groove 102. In this embodiment, after the battery module 10 leaves the frame 20, the anti-slip portion 212 still abuts against the inner peripheral wall of the receiving groove 102, so that the inner wall of the receiving groove 102 limits the position of the second end of the locking spring sheet 210, and avoids the elastic pusher 220 pushing the second end of the locking spring sheet 210 out of the receiving groove 102. Therefore, in the process of loading the battery module 10 into the frame 20, the anti-slip portion 212 can guide the second end of the locking spring sheet 210 into the receiving groove 102, so as to avoid the elastic secondary lock 200 hindering the battery module 10 from being loaded into the frame 20. In this way, the user does not need to align the second end of the locking spring sheet 210 with the receiving groove 102, thereby improving the convenience of loading the battery module 10 into the frame 20.

[0067] like Figure 7 As shown, in some embodiments, the elastic pusher 220 is a spring, and the elastic secondary lock 200 also includes a threaded fastener 230. One end of the elastic pusher 220 is fixedly connected to the first end of the battery assembly 100 by the threaded fastener 230, thereby avoiding the problem of the elastic pusher 220 being separated from the battery assembly 100 and improving the convenience of installing the elastic pusher 220.

[0068] like Figure 7 As shown, in some of the embodiments, the first end of the locking spring 210 is embedded in the first end of the battery assembly 100 , so that the first end of the locking spring 210 is fixed on the battery assembly 100 .

[0069] like Figure 7As shown, in some of the embodiments, a locking groove 2101 is formed on the side of the locking spring 210 facing away from the battery assembly 100 , and the mechanical lock 600 is used to be snapped onto the inner wall of the locking groove 2101 .

[0070] Compared with the prior art, the present invention has at least the following advantages:

[0071] 1. When disassembling the battery module 10, the user holds the first end of the battery module 10 with one hand, and at the same time, the fingers of the hand press the handle 300 in the direction of the battery assembly 100, specifically, press the portion of the handle 300 protruding from the outside of the frame 20, so that the handle 300 pushes the elastic secondary lock 200 to unlock, and then the hand pulls the battery module 10 in the direction of separating from the frame 20, so that the battery module 10 is completely separated from the frame 20, so as to achieve the effect of disassembling the battery module 10. In this way, the battery module 10 can be disassembled by one hand, which improves the convenience of disassembling the battery module 10 and the efficiency of disassembling the battery module 10.

[0072] 2. Since the handle 300 is arranged between the first end of the battery assembly 100 and the frame 20, after the battery module 10 is installed on the frame 20, the handle 300 is hidden inside the frame 20, that is, the handle 300 will not be exposed on the outside of the frame 20, thereby improving the compactness of the frame structure and further improving the structural compactness of the electric bicycle.

[0073] 3. Since the handle 300 does not protrude from the outside of the frame 20 after the battery module 10 is installed on the frame 20, the surface flatness of the electric bicycle is improved, the probability of the electric bicycle accidentally hitting the user is reduced, and the safety performance of the electric bicycle is improved.

[0074] The above-mentioned embodiments only express several implementation methods of the present disclosure, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the disclosed patent. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present disclosure, and these all belong to the protection scope of the present disclosure. Therefore, the protection scope of the disclosed patent shall be subject to the attached claims.
