Description

Technical Field

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

[0002] An electric bicycle is a vehicle that uses batteries as auxiliary energy and is equipped with motors, controllers, batteries, etc. on the basis of ordinary bicycles. In short, an electric bicycle is a bicycle that can be driven by batteries.

[0003] In the related art, an electric bicycle includes a tube, a front base, a rear base and a battery pack. An installation opening is provided on the outer side of the tube, and the installation opening is communicated with the interior of the tube. The front base and the rear base are both arranged inside the tube, the front base is close to the front end of the tube, and the rear base is close to the rear end of the tube. The front base and the rear base are respectively arranged corresponding to the two ends of the installation opening. The battery pack is arranged in the tube through the installation opening and clamped between the front base and the rear base. For example, the electric bicycle tube battery anti-dropping mechanism disclosed in document No. CN110155240A.

[0004] However, since the front base and the rear base are both fixedly connected inside the tube, the distance between the front base and the rear base is fixed. When the distance between the front base and the rear base is too short, the battery pack cannot be loaded into the tube; when the distance between the front base and the rear base is too long, the front base and the rear base cannot fit tightly with the battery pack, causing the battery pack to shake inside the tube. In order to ensure that the battery pack can be loaded into the tube and that the front base and the rear base can hold the battery pack, the distance tolerance between the front base and the rear base is strictly controlled, which leads to high requirements for the processing accuracy of the parts, which is not conducive to reducing the cost of electric bicycles.

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

[0058] 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:

[0059] Embodiment 1:

[0060] like Figure 1 As shown, the battery base 10 of the embodiment of the utility model includes a mounting base 100, the mounting base 100 is used to be located in the vehicle tube 20, and the mounting base 100 is provided with a locking surface 101, and the locking surface 101 is used to lock the battery pack in the vehicle tube 20. The battery base 10 also includes a fixing base 200, and the fixing base 200 is used to be fixedly installed in the vehicle tube 20. The mounting base 100 is movably connected to the fixing base 200, and the connection position of the mounting base 100 and the fixing base 200 is adjustable, so that the position of the locking surface 101 in the vehicle tube 20 is adjustable. By adjusting the position of the mounting base 100 on the fixing base 200, the locking surface 101 of the mounting base 100 can be made to fit closely to battery packs of different sizes. In this embodiment, before adjusting the position of the mounting base 100, the battery pack is placed in the vehicle tube 20, and then the position of the mounting base 100 is adjusted so that the locking surface 101 of the mounting base 100 is closely fitted with the battery pack, and then the locking surface 101 of the mounting base 100 and another base in the vehicle tube 20 jointly clamp the battery pack. It can be understood that further, the relative connection position of the mounting base 100 and the fixing base 200 is adjusted by the battery pack profiling member, and when adjusting the mounting base 100, the battery pack can also be replaced by the battery pack profiling member, which improves the convenience of installation and adjustment of the battery base 10.

[0061] The battery base 10 described above places the battery pack or the battery pack profiling part in the vehicle tube 20, and adjusts the position of the mounting base 100 so that the mounting base 100 and the battery pack or the battery pack profiling part fit closely together, so that the battery pack can be smoothly loaded into the vehicle tube 20 during the subsequent assembly operation, and the mounting base 100 can fit closely together with the battery pack during the subsequent assembly operation, so that the mounting base 100 and another base in the vehicle tube 20 can jointly clamp the battery pack to avoid the problem of the battery pack shaking. Since the position of the mounting base 100 can be adjusted to a position that fits closely with the battery pack, there is no need to control the distance tolerance between the mounting base 100 and another base in the vehicle tube 20, which can reduce the processing accuracy requirements of the parts, which is conducive to reducing the manufacturing cost of the electric bicycle.

[0062] like Figure 1 As shown, in some embodiments, the mounting base 100 includes a connecting portion 120 and a locking portion 130 , the connecting portion 120 is movably connected to the fixing base 200 , the locking portion 130 is fixedly connected to the connecting portion 120 , and the locking surface 101 is disposed on a side of the locking portion 130 facing away from the connecting portion 120 .

[0063] like Figure 1 As shown, preferably, the locking portion 130 is fixedly connected to the connecting portion 120 by a fastener. In other embodiments, the mounting base 100 is an integrally formed structure, that is, the locking portion 130 and the connecting portion 120 are connected together by integrally forming.

[0064] like Figure 1 As shown, in some embodiments, the fixing seat 200 is welded to the inner wall of the vehicle tube 20, avoiding fixing the fixing seat 200 by a connection structure exposed to the vehicle tube 20, improving the surface flatness of the vehicle tube 20, and further improving the surface flatness of the vehicle frame 10a. Of course, the fixing seat 200 can also be fixed to the inner wall of the vehicle tube 20 by other connection structures. For example, in some other embodiments, the fixing seat 200 is fixed to the inner wall of the vehicle tube 20 by fasteners such as screws or bolts.

[0065] like Figure 2 and Figure 3 As shown, in some embodiments, the mounting base 100 is further provided with a clearance through hole 104, the fixing base 200 is provided with a reinforcement hole 204, and the battery base 10 further includes a reinforcement member 700, which is passed through the clearance through hole 104, one end of the reinforcement member 700 is located in the reinforcement hole 204 and is threadedly connected to the fixing base 200, and the other end of the reinforcement member 700 abuts against the mounting base 100, so that the mounting base 100 is also fixedly connected to the fixing base 200 through the reinforcement member 700. In this embodiment, the locking member 300 is squeezed between the fixing base 200 and the mounting base 100, and then the reinforcement member 700 is passed through the clearance through hole 104, and the reinforcement member 700 is threadedly connected to the reinforcement hole 204, and the reinforcement member 700 is tightened so that the mounting base 100 is also fixedly connected to the fixing base 200 through the reinforcement member 700. In this way, the mounting base 100 is not only fixed to the fixing base 200 by the locking member 300 , but also fixed to the fixing base 200 by the reinforcing member 700 , so that the mounting base 100 has a double fixing structure, thereby improving the position stability of the mounting base 100 .

[0066] It can be understood that the reinforcement member 700 can be a screw, a bolt or other existing threaded connectors.

[0067] Embodiment 2:

[0068] The difference between this embodiment and embodiment 1 is that this embodiment further optimizes the structure of the battery base 10 of the utility model.

[0069] See also Figures 3 to 6 In this embodiment, the mounting base 100 is slidably connected to the fixing base 200, and the sliding direction of the mounting base 100 relative to the fixing base 200 is parallel to the adjustment direction of the locking surface 101 in the vehicle tube 20. In this embodiment, the mounting base 100 is pushed by manual or power elements to slide along the fixing base 200, and then the position of the locking surface 101 is adjusted, so that the locking surface 101 can fit tightly with the battery pack, and then the locking surface 101 and another base in the vehicle tube 20 clamp the battery pack together to avoid the problem of the battery pack shaking.

[0070] Of course, the mounting base 100 and the fixing base 200 are not limited to a sliding connection. For example, in other embodiments, the mounting base 100 is rollingly connected to the fixing base 200 via rollers, so that the position of the locking surface 101 of the mounting base 100 is adjustable.

[0071] like Figure 5 As shown, in some embodiments, one of the mounting base 100 and the fixing base 200 is provided with an adjustment slot 201, and the other of the mounting base 100 and the fixing base 200 is provided with an adjustment guide portion 110, and the adjustment guide portion 110 is slidably disposed in the adjustment slot 201, so that the mounting base 100 is slidably connected to the fixing base 200. In this embodiment, by sliding the adjustment guide portion 110 in the adjustment slot 201, the position adjustment of the mounting base 100 can be guided, thereby improving the smoothness of the adjustment of the mounting base 100. In this embodiment, the adjustment slot 201 is provided in the fixing base 200, the adjustment guide portion 110 is provided in the mounting base 100, and the adjustment guide portion 110 is slidably disposed in the adjustment slot 201. It can be understood that in other embodiments, the opening position of the adjustment slot 201 is interchanged with the setting position of the adjustment guide portion 110.

[0072] like Figure 5 As shown, in some of the embodiments, the adjustment guide portion 110 cooperates with the inner wall clearance of the adjustment slot 201 to reduce the sliding resistance of the mounting base 100 and improve the adjustment convenience of the mounting base 100 .

[0073] like Figure 5As shown, in some embodiments, the number of the adjustment slots 201 is two, and the two adjustment slots 201 are symmetrically arranged relative to the mounting base 100, the number of the adjustment guides 110 is two, and the two adjustment guides 110 are symmetrically arranged relative to the mounting base 100, and the two adjustment guides 110 are respectively slidably arranged in the two adjustment slots 201, so that the mounting base 100 is evenly stressed, the problem of the mounting base 100 being offset during adjustment is suppressed, and the adjustment accuracy of the mounting base 100 is improved. Of course, in some other embodiments, the number of the adjustment slots 201 and the adjustment guides 110 is not limited to two, and the number of the adjustment slots 201 and the adjustment guides 110 can be one, three, or other numbers.

[0074] Embodiment 3:

[0075] The difference between this embodiment and any of the above embodiments is that this embodiment further optimizes the structure of the battery base 10 of the utility model.

[0076] like Figure 1 and Figure 3 As shown, the battery base 10 of this embodiment further includes a locking member 300, which is used to lock the mounting base 100 after it is adjusted to a predetermined position relative to the fixing base 200, so that the mounting base 100 is relatively fixed to the fixing base 200. In this embodiment, after the position of the mounting base 100 is adjusted, the locking member 300 locks the mounting base 100, so that the mounting base 100 is fixedly connected to the fixing base 200, thereby avoiding the problem that the position of the mounting base 100 changes after the adjustment is completed.

[0077] Embodiment 4:

[0078] The difference between this embodiment and embodiment 3 is that this embodiment further optimizes the structure of the battery base 10 of the utility model.

[0079] like Figure 3 and Figure 4 As shown, the locking member 300 of this embodiment is used to be squeezed between the fixing seat 200 and the mounting base 100 after the mounting base 100 is adjusted to a predetermined position relative to the fixing seat 200, so that the battery base 10 is relatively fixed to the fixing seat 200. In this embodiment, after the position adjustment of the mounting base 100 is completed, the locking member 300 is squeezed between the fixing seat 200 and the mounting base 100, that is, the locking member 300 is clamped between the fixing seat 200 and the mounting base 100, so that the mounting base 100 is fixedly connected to the fixing seat 200 through the locking member 300, thereby avoiding the problem of the mounting base 100 being offset after the adjustment is completed.

[0080] like Figure 3As shown, in some embodiments, the fixing seat 200 is provided with a first extrusion surface 202, the mounting base 100 is provided with a second extrusion surface 102, and the locking member 300 is extruded between the first extrusion surface 202 and the second extrusion surface 102. In this embodiment, after the locking member 300 is extruded on the first extrusion surface 202 and the second extrusion surface 102, the locking member 300 abuts against the first extrusion surface 202 and the second extrusion surface 102 respectively, that is, the locking member 300 is clamped between the first extrusion surface 202 and the second extrusion surface 102, so that the mounting base 100 is fixedly connected to the fixing seat 200 through the locking member 300, thereby avoiding the problem of displacement of the mounting base 100 after the adjustment is completed.

[0081] like Figure 3 As shown, in some embodiments, there is an angle between the extension direction of the first extrusion surface 202 and the adjustment direction of the locking surface 101, so that the extrusion space formed between the first extrusion surface 202 and the second extrusion surface 102 gradually decreases along the extrusion direction of the locking member 300, which is conducive to the locking member 300 entering the extrusion space, thereby improving the convenience and efficiency of installing the locking member 300. Of course, in other embodiments, the extension direction of the first extrusion surface 202 can also be parallel to the adjustment direction of the locking surface 101.

[0082] like Figure 3 As shown, in some embodiments, the locking member 300 is an elastic structure, which improves the convenience and efficiency of the locking member 300 being squeezed between the mounting base 100 and the fixing base 200. It is understood that the locking member 300 can be a silicone coated structure, a rubber coated structure, a wooden block or other existing structures with a certain degree of elasticity.

[0083] like Figure 3 As shown, in some embodiments, the angle is greater than 0 degrees and less than 90 degrees, so as to ensure that a space for the locking member 300 to be squeezed can be formed between the first extrusion surface 202 and the second extrusion surface 102, and to ensure that the locking member 300 can be used to lock the mounting base 100 on the fixing base 200.

[0084] like Figure 3 and Figure 4 As shown, in some embodiments, the locking member 300 is provided with a first pressure surface 301, and the first pressure surface 301 abuts against the first extrusion surface 202, so that the surface of the locking member 300 abuts against the surface of the fixing seat 200, so that the connection area between the locking member 300 and the fixing seat 200 is larger, which helps to improve the locking stability of the locking member 300.

[0085] like Figure 3 and Figure 4As shown, in some embodiments, the locking member 300 is provided with a second pressure surface 302, and the second pressure surface 302 abuts against the second extrusion surface 102, so that the surface of the locking member 300 abuts against the surface of the mounting base 100, so that the connection area between the locking member 300 and the mounting base 100 is larger, which helps to improve the locking stability of the locking member 300.

[0086] It can be understood that in other embodiments, the first pressure-bearing surface 301 can also be replaced by a pressure-bearing edge or a pressure-bearing point, and the second pressure-bearing surface 302 can also be replaced by a pressure-bearing edge or a pressure-bearing point.

[0087] like Figure 3 and Figure 4 As shown, in order to squeeze the locking member 300 between the mounting base 100 and the fixing base 200 , the battery base 10 further includes a pushing member 400 , which is used to push the locking member 300 so that the locking member 300 is squeezed between the fixing base 200 and the mounting base 100 .

[0088] like Figure 3 As shown, in some embodiments, the locking member 300 is provided with an avoidance hole 303, the fixing seat 200 is provided with a connecting hole 203, the pushing member 400 is passed through the avoidance hole 303, the first end of the pushing member 400 is located in the connecting hole 203 and connected to the fixing seat 200, and the second end of the pushing member 400 is connected to the locking member 300, so that the locking member 300 is squeezed between the fixing seat 200 and the mounting base 100. Of course, in other embodiments, the positions of the avoidance hole 303 and the connecting hole 203 can also be swapped, that is, the locking member 300 is provided with a connecting hole 203, the fixing seat 200 is provided with the avoidance hole 303, the pushing member 400 is passed through the avoidance hole 303, the first end of the pushing member 400 is located in the connecting hole 203 and connected to the locking member 300, and the second end of the pushing member 400 is connected to the fixing seat 200.

[0089] like Figure 3 As shown, in some embodiments, the pusher 400 is a threaded fastener, a first end of the pusher 400 is located in the connection hole 203 and threadedly connected to the fixing seat 200 , and a second end of the pusher 400 abuts against the outer side of the mounting base 100 .

[0090] like Figure 3 As shown, further, the mounting base 100 is provided with a locking window 103, and the locking window 103 is arranged corresponding to the locking member 300. In this embodiment, after the position adjustment of the mounting base 100 is completed, the pushing member 400 is tightened through the locking window 103, so that the locking member 300 is fixed to the fixing base 200 through the pushing member 400, thereby avoiding interference of the mounting base 100 with the installation of the pushing member 400.

[0091] Of course, the pushing member 400 is not limited to a threaded fastener. For example, in other embodiments, the locking member 300 can also be a snap-on member. The first end of the locking member 300 is located in the connecting hole 203 but is snap-on to the fixing seat 200 , and the second end of the locking member 300 is abutted against the locking member 300 .

[0092] It is understandable that the pushing member 400 may also be a structure that is not fixedly connected to other parts. For example, in other embodiments, the pushing member 400 may also be a hammer, a connecting column, or other existing rigid structures that can be used for pushing.

[0093] Embodiment 5:

[0094] The difference between this embodiment and the third embodiment is that this embodiment further optimizes the structure of the battery base 10 of the utility model, and the locking member of this embodiment is different from the locking member of the fourth embodiment.

[0103] It can be understood that a locking window 103 is provided on the outer side of the vehicle tube 20 , and the locking window 103 is arranged corresponding to the second end of the locking member 300 , so that a screwdriver can screw the locking member 300 through the locking window 103 .

[0104] Embodiment 8:

[0105] The difference between this embodiment and any of the above embodiments is that this embodiment further optimizes the structure of the battery base 10 of the utility model.

[0106] like Figure 3 as well as Figures 7 to 9As shown, the battery base 10 of this embodiment further includes an elastic member 500, which is located between the fixing base 200 and the mounting base 100, and elastically abuts against the fixing base 200 and the mounting base 100 respectively, and is used to push the mounting base 100 so that the locking surface 101 is adjusted to a predetermined position. In this embodiment, the elastic member 500 automatically pushes the mounting base 100 to adjust to a position that is closely fitted with the battery pack, thereby improving the automation of adjusting the mounting base 100, thereby improving the convenience and efficiency of adjusting the mounting base 100.

[0107] It is understandable that the elastic member 500 may also be a spring, a silicone member, a rubber member or other existing elastic members 500. Of course, in other embodiments, the elastic member 500 may also be replaced by a linear drive member, such as an electric telescopic rod, a motor or other existing linear drive members.

[0108] It should be emphasized that, in other embodiments, the elastic member 500 may be omitted from the battery base 10 , and the base 100 may be manually pushed and installed.

[0109] like Fig. 9 As shown, in some embodiments, the battery base 10 also includes a fixing member 600, and the fixing member 600 is used to fix the elastic member 500 to the fixing seat 200 and / or the mounting base 100, that is, the fixing member 600 is used to fix the elastic member 500 to at least one of the fixing seat 200 and the mounting base 100 to avoid the problem of the elastic member 500 falling off the mounting position, ensuring that the elastic member 500 can push the mounting base 100 to a position that fits tightly with the battery pack.

[0110] like Fig. 9 As shown, further, a threaded hole is opened on one side of the mounting base 100 , and one end of the fixing member 600 is located in the threaded hole and is threadedly connected to the mounting base 100 .

[0111] Embodiment 9:

[0112] The difference between this embodiment and embodiment 1 is that this embodiment further optimizes the structure of the battery base 10 of the utility model, and the position adjustment structure of this embodiment is different from the position adjustment structures of embodiments 2 and 7.

[0113] like Fig.10As shown, the battery base 10 of this embodiment further includes an electric push rod 800, which is mounted on the fixing base 200, and the power output end of the electric push rod 800 is fixedly connected to the mounting base 100. The electric push rod 800 is used to drive the mounting base 100 to move relative to the fixing base 200, so that the mounting base 100 is movably connected to the fixing base 200 through the electric push rod 800. In this embodiment, the mounting base 100 is driven to move by the electric push rod 800, so that the position of the locking surface 101 of the mounting base 100 in the vehicle tube 20 is adjustable, thereby enabling the locking surface 101 to fit tightly with the battery pack. After the electric push rod 800 stops driving, the mounting base 100 reaches a predetermined position, and at this time, the position of the mounting base 100 also remains fixed, that is, the position of the mounting base 100 is adjusted by the electric push rod 800, and the position of the mounting base 100 is also fixed by the electric push rod 800. It can be understood that since the battery push rod 800 can fix the mounting base 100 , the locking member 300 can be omitted from the battery base 10 .

Since the position of the mounting base 100 can be adjusted to a position that fits closely with the battery pack, there is no need to control the distance tolerance between the mounting base 100 and another base in the vehicle tube 20, which can reduce the processing accuracy requirements of the parts, which is conducive to reducing the manufacturing cost of the electric bicycle.

[0118] like Fig.11 As shown, in some of the embodiments, the frame 10a further includes a battery pack 30 , which is located in the vehicle tube 20 and connected to the mounting base 100 . Specifically, the battery pack 30 fits tightly to the mounting base 100 .

Since the position of the mounting base 100 can be adjusted to a position closely fitting with the battery pack 30, there is no need to control the distance tolerance between the mounting base 100 and another base in the vehicle tube 20, which can reduce the processing accuracy requirements of the parts, which is conducive to reducing the manufacturing cost of the electric bicycle.
