Detailed Description
The present application will be described in further detail with reference to the drawings and examples, in order to make the objects, technical solutions and advantages of the present application more apparent. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the scope of the application.
At present, with the development of scientific technology, a low-beam flashlight is widely used as a handheld tool for emergency illumination in industrial maintenance and outdoor activities, such as illumination when workers perform maintenance operation of machine equipment, illumination when field operation or emergency illumination, and the like. The conventional flashlight generally has a display assembly and a control assembly disposed on a barrel of the flashlight, so that the flashlight has poor operability.
In view of this, and referring to fig. 1-5, the present application provides a flashlight having an operating assembly and display assembly 300 that can be on a handle 100. Specifically, the flashlight includes a flashlight body 200 and a handle 100. The flashlight body 200 includes a housing. The handle 100 includes a handle housing 110, a display assembly 300, and an operating assembly. The handle shell 110 is connected with the outer shell, the display assembly 300 and the operation assembly are connected to the handle shell 110, the display assembly 300 and the operation assembly are electrically connected with the control module of the flashlight body 200, the display assembly 300 is used for displaying the running state of the flashlight, and the operation assembly is used for controlling the running state of the flashlight. The operating states of the flashlight comprise: near-far light display state, electric quantity state, displayed time, residual display time, current real-time and other information.
The application provides a flashlight with an operation assembly and a display assembly 300 on a handle 100, which comprises the handle 100 and a flashlight body 200, wherein the handle 100 can be used for conveniently holding the flashlight by a user. In this embodiment, the flashlight includes a display assembly 300 for displaying an operation state and a control assembly for controlling the operation state, and in particular, the control assembly and the display assembly 300 are both disposed on the handle 100 of the flashlight, so that on one hand, a user can control the operation state of the flashlight with one hand conveniently, and on the other hand, the assembly efficiency of the flashlight can be improved, because the control assembly and the display assembly 300 can be assembled before the handle 100 is installed. Yet another aspect also facilitates a user's real-time viewing of the operational status of the flashlight because the display assembly 300 is on the handle 100, the display assembly 300 being closer to the user's eyes than is provided on the flashlight body 200.
In a further embodiment, the display assembly 300 is disposed inside the handle housing 110, the display assembly 300 includes a display screen, and the handle housing 110 includes a window portion 113 facing away from the flashlight body 200 and opposite to the display screen, and the window portion 113 is transparent. Referring to fig. 1 and 4, in the present application, a display screen is not provided at an outer side of a handle case 110, but is provided at an inner side of the handle case 110, and then a transparent window part 113 is provided at the handle case 110 with the window part 113 facing the display screen, so that display information of the display screen can be acquired by a user through the window part 113. On the one hand, the window portion 113 can well protect the display screen, and on the other hand, can also play a role in preventing water and scraping.
In a further embodiment, the handle housing 110 is curved and the handle housing 110 includes an outer side facing away from the flashlight body 200 and an inner side adjacent to the flashlight body 200. The handle case 110 includes an outer panel 110 located at the outer side, the outer panel 110 including a window portion 113, the outer panel 110 having a width equal to the width of the handle case 110, and the outer panel 110 having a length equal to the length of the handle case 110. That is, the plate member on the outer side of the handle housing 110 is an elongated integrally formed arcuate plate. Such a structural design can improve the sealability of the handle 100.
The inventor considers that the flashlight may fall during use, and when the display assembly 300 and the control assembly are both disposed on the raised handle 100, the risk of damage to the display assembly 300 and the control assembly may be increased. In a further embodiment, the steering assembly is disposed inside the handle housing 110. Thus, even if the flashlight falls down, the damage to the control assembly of the flashlight can not be caused. Meanwhile, when the control component is arranged on the inner side of the handle shell 110 of the flashlight, the flashlight is more convenient to control.
In a further embodiment, the steering assembly includes a switch button 220, a low-beam control button 210, and an emergency light control button 230. In a further embodiment, the handle shell 110 includes an inner side plate 112 positioned on the inner side, the width of the inner side plate 112 being equal to the width of the handle shell 110, and the length of the inner side plate 112 being equal to the length of the handle shell 110. The inner panel 112 includes a recess 114 for accommodating a finger, and a switch button 220, a low-high beam control button 210, and an emergency light control button 230 are provided in the recess 114. Referring to fig. 2-3, four depressions 114 are provided on the inner side plate 112 of the handle housing 110, and the index finger and middle finger of a user when the user holds the handle 100. The ring finger and the little finger are respectively sunk into the four depressions, so that the holding feeling of a user can be enhanced, and the comfort level of the hand-held flashlight is improved.
In a further embodiment, the inner panel 112 includes three recesses 114 (including at least three recesses 114, four recesses 114 in FIGS. 2-3), the three concave portions 114 are in one-to-one correspondence to accommodate the index finger, middle finger and ring finger of the user, and the switch button 220, the near-far light control button 210 and the emergency light control button 230 are provided in one-to-one correspondence to the three concave portions 114. That is, when the user holds the flashlight, the user can operate one button with one finger, thereby realizing all operation actions of the flashlight. By means of the structure, a user can control the flashlight with one hand without searching the position of the control button when the flashlight is controlled (for a large-sized outdoor flashlight, the existing flashlight is difficult to control with one hand due to the fact that the size and the weight are large).
In the foregoing embodiment, each of the recesses 114 on the handle 100 is provided with a manipulation button, and in another embodiment, referring to fig. 4-5, the near-far light control button 210 may include a support column having one end connected to the inner side of the handle housing 110 and the other end extending toward the flashlight body 200, and a pressing plate 211. The middle part of the pressing plate 211 is hinged with the other end of the supporting column, the pressing plate 211 comprises a first end and a second end which are oppositely arranged, a first far-reaching light control contact 213 is arranged on the wall surface, close to the handle shell 110, of the first end, a second far-reaching light control contact matched with the first far-reaching light control contact 213 is arranged on the handle shell 110, and the first far-reaching light control contact 213 and the second far-reaching light control contact control whether the flashlight enters a far-reaching light state or not through contact or separation; the wall surface of the second end, which is close to the handle shell 110, is provided with a first low beam control contact 214, the handle shell 110 is provided with a second low beam control contact matched with the first low beam control contact 214, and the first low beam control contact 214 and the second low beam control contact are contacted or separated to control whether the flashlight enters a low beam state or not.
In the above embodiment, when the pressing plate 211 of the low-beam and high-beam control button 210 rotates relative to the supporting column 212 until the first low-beam control contact 214 contacts the second low-beam control contact, the first high-beam control contact 213 is separated from the second high-beam control contact, and the flashlight is in the low-beam mode. When the pressing plate 211 rotates relative to the supporting column 212 until the first high beam control contact 213 contacts the second high beam control contact, the first low beam control contact 214 is separated from the second low beam control contact, and the flashlight is in the high beam mode. Also, when the user holds the handle 100, the user's hand can hold the pressing plate 211 at the same time, that is, the user can control the flashlight to be in the low beam mode or the high beam mode by controlling the pressure of the index finger or the pressure of the ring finger during the holding of the handle 100. The operation is very convenient. The switching of far and near light can be greatly facilitated, so that a user can conveniently switch to a near light mode when the near light function is needed, the endurance of the flashlight is improved (the conventional far and near light control is troublesome to operate, and the user is not required to switch from the far light mode to the near light mode when the user needs to illuminate a near object, so that the energy consumption of the flashlight is higher).
The low-high beam control button 210 further includes an elastic member connected to the support column and the pressing plate 211, respectively, and the elastic member is configured to generate an elastic force to make the first low beam control contact 214 contact with the second low beam control contact. That is, in the present embodiment, under the normal state, the first low beam control contact 214 of the pressing plate 211 contacts the second low beam control contact on the handle housing 110 due to the elastic member, the flashlight is in the low beam mode, and when the user holds the handle 100, the user can press the end portion of the pressing plate 211 with the first high beam contact without force if he wants to put the flashlight in the low beam mode. When the user wants to put the flashlight in the high beam mode, the end portion of the pressing plate 211 having the first high beam contact may be continuously pressed, and since the flashlight itself has a certain weight, the pressing plate 211 may be pressed by the weight of the flashlight itself when the user holds the flashlight, that is, the user may change the position of the pressing plate 211 by holding the position of the handle 100, which is very convenient. Moreover, as the flashlight defaults to be in the low beam mode, the electric quantity of the flashlight can be further saved, and the cruising performance of the flashlight is improved (because the switching of the low beam and the high beam is more troublesome in the prior art, a user is required to light a nearby object and is lazy to switch the high beam into the low beam, so that the cruising is poorer).
In one embodiment, the elastic member is a torsion spring and is respectively connected to the support column 212 and the middle part of the pressing plate 211, in another embodiment, the elastic member is a spring, one end of the elastic member is connected to the inner side wall surface of the handle shell 110, and the other end of the elastic member is connected to the wall surface of the pressing plate 211 facing the handle shell 110.
In a further embodiment, the pressing plate 211 extends along the length direction of the handle case 110, and the length of the pressing plate 211 is greater than half the length of the handle case 110 and less than three quarters of the length of the handle case 110. When the pressing plate 211 is in the above-described size, it is more convenient for the user to hold the pressing plate 211.
The inventor has considered that when the user needs the flashlight to be in the high beam mode, the front end of the flashlight is tilted more upward (because the flashlight is to illuminate a far location), and when the user needs the flashlight to be in the low beam mode, the front end of the flashlight is depressed more (because the flashlight is to illuminate a location in front of the user's foot). When the front end of the flashlight is tilted up, the rear end of the outside of the handle 100 has downward pressure (pressure imparted to the handle 100 by the hand when held by the hand of the user), and the front end of the inside of the handle 100 has upward pressure. When the front end of the flashlight is depressed, the front end of the outside of the handle 100 has downward pressure and the rear end of the inside of the handle 100 has upward pressure. Based on this, in one embodiment, the first low beam control contact 214 is located on the rear side of the first high beam control contact 213 and the second low beam control contact is located on the rear side of the second high beam control contact. Thus, when the flashlight is in the high beam mode, the user's hand applies appropriate pressure to the end of the pressing plate 211 having the first high beam control contact 213, thereby controlling the flashlight to be in the high beam mode. When the flashlight is in the high beam mode, the user's hand gives appropriate pressure to the end portion of the pressing plate 211 having the first low beam control contact 214, so as to control the flashlight to be in the low beam mode, i.e. the position design of the pressing plate 211 in this embodiment can match the hand pressure of the flashlight in the use state, so that the flashlight is switched between the low beam and the high beam more smoothly.
Further, the present inventors have considered that when the user needs the flashlight to perform the high beam irradiation, although the front end of the flashlight is required to be tilted up, the tilt angle is not too high, so in one embodiment, the handle housing 110 includes an inner plate 112 facing the pressing plate 211, the inner plate 112 is connected to the support column 212, the inner plate 112 is disposed to intersect with the optical axis of the flashlight, and the distance from the front end of the inner plate 112 to the optical axis is smaller than the distance from the rear end of the inner plate 112 to the optical axis. That is, when the optical axis of the flashlight is horizontal, the inner side plate 112 is inclined downward from back to front, so that even if the user's hand gives a proper pressure to the front end of the pressing plate 211, the front end of the flashlight will not be excessively tilted up, and the operation is more convenient.
To further prevent the front end of the flashlight from tilting excessively when the flashlight is in the high beam state, in one embodiment, the center of gravity of the flashlight is located forward of the center of the support post 212 in a direction parallel to the optical axis of the flashlight.
In one embodiment, the present inventors have contemplated that when a user holds flashlight handle 100, the user may experience reduced comfort in holding due to the fact that only one end of pressure plate 211 is stressed. To enhance the comfort of gripping, in one embodiment, referring to fig. 4, the support column 212 is slidably coupled to the handle housing 110 such that the support column 212 can slide relative to the handle housing 110 along its length direction, thereby conforming the pressing plate 211 to the handle housing 110. A return spring is connected between the support post 212 and the handle housing 110, and the return spring is used for generating an elastic force for pushing the support post 212 away from the handle housing 110 (and the elastic force is greater than the elastic force of the elastic member of the near-far light control button 210). The flashlight further comprises a controller, wherein the controller obtains the contact state of the first low beam control contact 214 and the first high beam control contact 213 before the support column 212 is retracted in the handle shell 110 when the support column 212 is retracted in the handle shell 110, and correspondingly controls the operation state of the flashlight according to the contact state when the support column 212 is completely retracted in the handle shell 110 and the pressing plate 211 is attached to the handle shell 110. That is, the support column 212 in the present embodiment can slide to the inside of the handle case 110 with respect to the handle case 110 so that both ends of the pressing plate 211 can be fitted to the inside of the handle case 110. With the above-mentioned scheme, the user can press one end of the pressing plate 211 first, and then press the pressing plate 211 with force so that both ends of the pressing plate 211 are attached to the inner side of the handle case 110. When the user needs the low beam, the pressing plate 211 can be directly pressed to be attached to the handle housing 110 (because the first low beam control contact is contacted with the second low beam control contact in the initial state), so that the support column 212 is retracted to the inside of the handle housing 110. When the user needs the high beam, the end portion of the pressing plate 211 having the first high beam control button may be pressed first, and then the support column 212 is pressed into the handle case 110 with force, so that both ends of the pressing plate 211 are attached to the inner side of the handle case 110. The controller is used for recording the contact state between the first low beam control contact 214 and the second low beam control contact, the first high beam control contact 213 and the second high beam control contact before the support column 212 is retracted, and taking the contact state before the support column 212 is retracted as the running state of the final flashlight, so that even if the support column 212 is retracted, the first low beam control contact 214 is simultaneously contacted with the second low beam control contact, the first high beam control contact 213 and the second high beam control contact, the control of the flashlight is not influenced.
That is, when the support column 212 is retracted, if the first far-reaching control contact 213 is in contact with the second far-reaching control contact, the controller controls the flashlight to operate in the far-reaching state after the support column 212 is completely retracted into the handle housing 110 and the pressing plate 211 is attached to the handle housing 110. When the support column 212 is retracted, if the first high beam control contact 213 is in contact with the second high beam control contact, the controller controls the flashlight to operate in the high beam state after the support column 212 is completely retracted into the handle housing 110 and the pressing plate 211 is attached to the handle housing 110.
