Description

A kind of built-in bottom-open type battery pack device of Lower tube of electric bicycle

Technical field

The utility model relates to a kind of built-in bottom-open type battery pack devices of Lower tube of electric bicycle, belong to mechanical technique neck Domain.

Background technique

The lock for opening used in battery in existing electric bicycle under down tube is divided into mechanical lock, springlock.In down tube bottom-open type When battery under mechanical lock structure state, needs to be propped with a hand handle battery always in placing battery and lock, exist and do not allow Yi Suo, being easy to slip out of the hand when opening when taking falls situation.The spring lock structure shape in down tube bottom-open type battery It under state, needs to press when placing or claps, there is false lock risk in this way, situation can be fallen when riding or letting go, such as Fruit amplifies gap in structure and loosens to avoid false lock risk but can exist after battery is placed in this way, there is bumpy road when riding Battery can be allowed to fall under state.

Summary of the invention

For overcome the deficiencies in the prior art, the utility model provides a kind of built-in bottom-open type battery of Lower tube of electric bicycle Box device.

A kind of built-in bottom-open type battery pack device of Lower tube of electric bicycle, including two locking devices, battery case, battery case and Battery, two locking devices include pedestal, lock housing, mechanical lock, silent door lock lock core, lock tongue, shaft, spring and handle, and two The pedestal of locking device is connect with lock housing, and mechanical lock is connected in the lock core hole of lock housing side, is connected respectively in the cavity of lock housing top surface Silent door lock lock core and lock tongue are connect, lock tongue is connect with mechanical lock, and shaft, one end connecting spring of shaft are connected in the hole of pedestal And handle.

Two locking devices are embedded in the side of the battery case of battery case, and battery is mounted in battery case, two locking devices The one side of silent door lock lock core and lock tongue can lock battery to the side of battery.Shaft is locked by screw and handle, bullet Spring one end heads on shaft, and the spring other end heads on pedestal.

The utility model has the advantages that improving row in the structure of mechanical lock increases by two locks, while two locks use Quite mature lock core structure of door lock is combined.Functionally guarantee to slip out of the hand when battery is pressed into and tangles battery and will not fall It falls, carries out lock mechanical lock again later, can guarantee will not allow battery to fall risk when taking, putting battery.First of lock is mechanical lock It can prevent the false lock status of springlock, second lock is the mute springlock of door lock core, on pattern handling, can allow the second head The amplification of Protective lock gap, springlock will not be allowed false lock status occur, then lock battery by first of mechanical lock correcting.

Detailed description of the invention

When considered in conjunction with the accompanying drawings, by referring to following detailed description, it can more completely more fully understand that this is practical new Type and being easy learns many adjoint advantages, but attached drawing described herein is used to provide to the utility model into one Step understands, constitutes a part of the utility model, and the illustrative embodiments and their description of the utility model are practical for explaining It is novel, it does not constitute improper limits to the present invention, such as schemes wherein:

Fig. 1 is the separate structure schematic diagram of the utility model.

Fig. 2 is the structural schematic diagram of the utility model.

Fig. 3 is the battery pack structure schematic diagram of the utility model.

Fig. 4 is the battery case and battery connecting construction schematic diagram of the utility model.

The present invention will be further described with reference to the accompanying drawings and examples.

Specific embodiment

Obviously, those skilled in the art are belonged to originally practical based on many modifications and variations that the objective of the utility model is done Novel protection scope.

Obviously, those skilled in the art of the present technique are appreciated that term " first ", " second " are used for description purposes only, without It can be interpreted as indication or suggestion relative importance or implicitly indicate the quantity of indicated technical characteristic.Define as a result, " the One ", the feature of " second " can explicitly or implicitly include one or more of the features.In the de-scription, " multiple " It is meant that two or more, unless otherwise specifically defined.

Unless otherwise clearly defined and limited, the terms such as term " installation ", " connected ", " connection ", " fixation " should be done extensively Reason and good sense solution may be a detachable connection for example, it may be being fixedly connected, or be integrally connected；It can be mechanical connection, It can be electrical connection；It can be directly connected, the company inside two elements can also be can be indirectly connected through an intermediary It is logical.For the ordinary skill in the art, it can understand above-mentioned term in the present invention as the case may be Concrete meaning.

Those skilled in the art of the present technique are appreciated that unless otherwise defined, all terms used herein (including technology art Language and scientific term) there is meaning identical with the general understanding of the those of ordinary skill in fields.

Embodiment 1: shown in as shown in Figure 1, Figure 2, Fig. 3 and Fig. 4, a kind of built-in bottom-open type battery of Lower tube of electric bicycle is box-packed It sets, including two locking devices, battery case 9, battery case 10 and battery 11, two locking devices include pedestal 1, lock housing 2, mechanical lock 3, silent door lock lock core 4, lock tongue 5, shaft 6, spring 7 and handle 8.

The pedestal 1 of two locking devices is connect with lock housing 2, and mechanical lock 3 is connected in the lock core hole of 2 side of lock housing, and lock housing 2 is pushed up Silent door lock lock core 4 and lock tongue 5 are separately connected in the cavity in face, lock tongue 5 is connect with mechanical lock 3, and connection turns in the hole of pedestal 1 Axis 6, one end connecting spring 7 and handle 8 of shaft 6, shaft 6 are locked by screw and handle 8,7 sets of spring in shaft 6, bullet One end of spring 7 is connect with handle 8, and spring 7 is put in shaft 6, and 7 one end of spring heads on shaft 6, and 7 other end of spring heads on pedestal 1 It fall shaft 6 will not downwards, two locking devices are embedded in the side of the battery case 10 of battery case 9, and battery 11 is mounted on battery case In 10, the silent door lock lock core 4 of two locking devices and the one side of lock tongue 5 can lock battery 11 to the side of battery 11.

Two lock (including mechanical lock and silent door lock) of increase is improved in the structure of mechanical lock, while two locks are adopted Use lock core structure of door lock.

Functionally guarantee to slip out of the hand when battery is pressed into and tangle battery and do not fall out, carries out lock mechanical lock, energy again later Guarantee battery will not be allowed to fall risk when taking, putting battery.

First of lock (mechanical lock) is the false lock status that mechanical lock can prevent springlock, and it is door that second, which locks (silent door lock), The mute springlock of lock pin allows the Protective lock gap of second to amplify on pattern handling, and springlock will not be allowed false lock occur State, then pass through first of mechanical lock locking battery.

As described above, being explained in detail to the embodiments of the present invention, as long as but essentially without disengaging The inventive point and effect of the utility model can have many deformations, this is apparent to one skilled in the art 's.Therefore, such variation is also integrally incorporated within the protection scope of the utility model.
