In a preferred embodiment, when the fastener is locked in place by the casing and the case lid, institute Case lid is stated to drive the touching control to touch the travel switch and close the travel switch.
In the fastener detection structure that the utility model is provided, the detection structure of setting can automatic detection fastener installation Whether in place, manpower is saved, detection efficiency is improved, and can detect whether the installation of fastener is installed in place in real time, is had Beneficial to the traffic safety of electric automobile.
【Brief description of the drawings】
Fig. 1 detects the structural representation of structure in the first embodiment for the fastener that the utility model is provided.
Fig. 2 detects the structural representation of structure in this second embodiment for the fastener that the utility model is provided.
【Embodiment】
In order that the purpose of this utility model, technical scheme and advantageous effects become apparent from understanding, below in conjunction with attached Figure and embodiment, the utility model is further elaborated.It should be appreciated that described in this specification Embodiment is not intended to limit the utility model just for the sake of explaining the utility model.
Fig. 1 is refer to, structure 100, including electricity are detected for a kind of fastener that the utility model first embodiment is provided Pond case 10, some fasteners 20 and detection structure 30.
The battery case 10 includes offering some first through hole 111 on casing 11 and case lid 12, the casing 11, described Some the second through holes 121 for corresponding and connecting with the first through hole 111 are offered on case lid 12.
In the present embodiment, the fastener 20 is fastening screw.
The detection structure 30 includes the switching signal detection being arranged on the casing 11 and warning circuit 31 and some Travel switch 32, the switching signal detection and warning circuit 31 can control carry out sound and/or light alarm.Some strokes are opened Close 32 strings and/or be connected in parallel on the switching signal detection and warning circuit 31, the position of each travel switch 32 is corresponded In the position of the fastener 20.In other embodiments, the position of the travel switch 32 and quantity can be entered as needed Row adjustment.
The fastener 20 is sequentially inserted into the second through hole 121 of the case lid 12 and the first through hole of the casing 11 111 interior and the be locked casing 11 and the case lids 12.The stroke is touched when the fastener 20 is installed in place to open Closing 32 causes the travel switch 32 to close, the switching signal detection and warning circuit 31 and some shapes of travel switch 32 Into loop.The state of the switching signal detection and 31 pairs of the warning circuit travel switch 32 is detected, if detected The travel switch 32 is open mode, then represents the fastener 20 and loosen, it is impossible to touch the travel switch 32 and close, this The loop that Shi Suoshu switching signals are detected and warning circuit 31 is formed with some travel switches 32 disconnects, the switching signal Detection and the output alarm signal carry out sound of warning circuit 31 and/or light alarm;If it is closure to detect the travel switch 32 State, then represent the fastener 20 and do not loosen, now switching signal detection and warning circuit 31 not output alarm signal.
Fig. 2 is refer to, structure 200, the fastener are detected for the fastener that the utility model second embodiment is provided 20 can be placed in the outside of the battery case 10, and the case lid 12 also includes inwall 122, the detection structure 30 also include with it is described The one-to-one touching control 33 of travel switch 32.The touching control 33 is located on the inwall 122 of the case lid 12.When the fastening When part 20 is locked in place by the casing 11 and the case lid 12, it is described that the case lid 12 drives the touching control 33 to touch Travel switch 32 simultaneously closes the travel switch 32, and the switching signal detection and warning circuit 31 are opened with some strokes Close 32 and form loop.Further detected by the switching signal and the state of 31 pairs of the warning circuit travel switch 32 is carried out Detection, if detecting the travel switch 32 for open mode, represents the fastener 20 and loosens, and then causes described touch Control 33 can not touch the travel switch 32 and close, now the switching signal detection and warning circuit 31 and some rows The loop of the formation of Cheng Kaiguan 32 disconnects, the switching signal detection and the output alarm signal carry out sound of warning circuit 31 and/or light Alarm;If detecting the travel switch 32 for closure state, represent the fastener 20 and do not loosen, now the switch Signal detection and warning circuit 31 not output alarm signal.In present embodiment, the touching control 33 is sheet metal.
In first and second above-mentioned embodiment, the fastener 20 is sequentially inserted into the second through hole of the case lid 12 121 and the casing 11 first through hole 111 in and the be locked casing 11 and the case lid 12 so that the stroke is opened Close 32 to close, the switching signal detection and warning circuit 31 and some travel switches 32 formation loop;The switching signal inspection Survey and the state of 31 pairs of the warning circuit travel switch 32 is detected and defeated when the travel switch 32 is open mode Go out alarm signal to be alarmed.
In the fastener detection structure that the utility model is provided, the detection structure of setting can automatic detection fastener installation Whether in place, manpower is saved, detection efficiency is improved, and can detect whether the installation of fastener is installed in place in real time, is had Beneficial to the traffic safety of electric automobile.
