DETAILED DESCRIPTION

[0061] The following will be combined with the drawings in the embodiments of the present disclosure to clearly and completely describe the technical solutions in the embodiments of the present disclosure. Obviously, the described embodiments are part of the embodiments of the present disclosure, rather than all of the embodiments. Based on the embodiments in the present disclosure, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present disclosure.

[0062] The directional nouns involved in the embodiments of the present disclosure, such as "upper", "lower", "side", etc., are generally based on the relative directional relationship between the structures when the components of the lighting device are usually arranged, and these directional nouns are used only to more clearly describe the relationship between the structures, not to describe the absolute directional. When the components of the lighting device are placed in different postures, the directional position may change, for example, "upper" and "lower" may be interchangeable.

[0063] Unless otherwise defined, all technical terms used in the embodiments of the present disclosure have the same meanings as commonly understood by those of ordinary skill in the art.

[0064] In order to make the technical solutions and advantages of the present disclosure more clear, the embodiments of the present disclosure will be further described in detail below with reference to the accompanying drawings.

[0065] In a first aspect, an embodiment of the present disclosure provides a lighting device.

[0066] refer to Figure 1-4 The lighting device includes a lighting part 11 and a multifunctional part 12, the lighting part 11 and the multifunctional part 12 are respectively located at two opposite ends of the lighting device, the multifunctional part 12 includes a window breaking assembly 121, and the window breaking assembly 121 includes a window breaking main body 1211, a striker 1212 and a first elastic member 1213;

[0067] The window breaking body 1211 has a first accommodating cavity 12111 and a first opening 12112. The striker 1212 includes a driving portion 12121, a mounting portion 12122 and a needle head 12123. The needle head 12123 and the mounting portion 12122 are respectively located at two opposite ends of the striker 1212.

[0068] One end of the first elastic member 1213 is mounted on the inner wall of the first accommodating cavity 12111, and the other end is mounted on the mounting portion 12122. The mounting portion 12122 and the first elastic member 1213 are located in the first accommodating cavity 12111;

[0069] When the driving portion 12121 is driven to move in the first direction, the firing pin 1212 squeezes the first elastic member 1213, causing the first elastic member 1213 to be compressed; when the driving portion 12121 is released, the needle head 12123 of the firing pin 1212 at least partially extends out of the first accommodating cavity 12111 through the first opening 12112 under the action of the elastic force of the first elastic member 1213.

[0070] In the embodiment of the present disclosure, the two ends of the lighting device are respectively set as the lighting part and the multifunctional part, so that the lighting function and other multiple functions (including the window breaking function) can be realized by means of the two ends of the lighting device, and at the same time, the different functions are not easy to interfere with each other. The window breaking assembly of the multifunctional part has a striker, and the striker is installed on the window breaking main body by means of the cooperation of the first elastic member and the mounting part. At least part of the striker (such as the mounting part) can be located in the first accommodating cavity, so that at least partial encapsulation of the striker can be achieved. The first elastic member can be completely placed in the first accommodating cavity to achieve the encapsulation of the first elastic member by means of the window breaking main body. The driving part of the striker can drive the striker to squeeze the first elastic member, so that the first elastic member accumulates force, so that when the first elastic member releases the elastic potential energy, the needle head of the striker is driven to be ejected from the first opening of the window breaking main body at a relatively high speed. Here, the movement of the driving part can be achieved by the user's top pressure, or an additional top pressure member (as described later) is provided in the window breaking assembly, and the top pressure member is used to achieve the top pressure.

[0071] That is, the embodiment of the present disclosure provides a lighting device, which has a lighting part and a multifunctional part. The multifunctional part has a built-in window breaking assembly, which can realize the lighting and window breaking functions through the same device at the same time, which is conducive to reducing the space occupied by the vehicle cabin. Among them, in the window breaking assembly, the striker has a driving part. When the driving part is driven to move in the first direction, the movement of the striker will squeeze the first elastic member, so that the first elastic member accumulates force; when the driving part is released, the elastic potential energy of the first elastic member is released, so that the needle head of the striker is ejected from the first opening of the window breaking body at a higher speed, and the glass is broken with a greater impact force. It can be seen that with the help of the driving part, the user's operation when breaking the window can be simplified, and with the help of the first elastic member, the window breaking efficiency of the window breaking assembly can be improved.

[0072] In some embodiments, reference Figure 3-5 , the window breaking assembly 121 further includes a top pressing member 1214;

[0073] The pressing member 1214 is slidably mounted on the window-breaking body member 1211 and is at least partially located outside the first accommodating cavity 12111;

[0074] When the pressing member 1214 is pressed, it can drive the driving portion 12121 to move in the first direction.

[0075] In this embodiment, a pressing member is additionally provided which is slidably mounted on the window-breaking main body. When the pressing member is pressed, it can drive the driving part to move in the first direction, thereby driving the striker and compressing the first elastic member. At the same time, the pressing member is at least partially located outside the first accommodating cavity, which reserves an operating space for the user to operate the pressing member, thereby improving the user's operating convenience.

[0076] In some embodiments, reference Figure 5 The window breaking assembly 121 further includes a second elastic member 1215, the pressing member 1214 has a first pressing end 12141 and a second protecting end 12142, the second protecting end 12142 has a second opening 121421, and the second protecting end 12142 is at least partially located outside the first accommodating cavity 12111;

[0077] One end of the second elastic member 1215 is mounted on the second protection end 12142, and the other end is mounted on the needle head 12123;

[0078] The second elastic member 1215 biases the needle head 12123 to retract inward relative to the second opening 121421 toward the mounting portion 12122 , and biases the first pressing end 12141 to a state where there is a gap between the first pressing end 12141 and the driving portion 12121 ;

[0079] When the pressing member 1214 is pressed, it overcomes the biasing force of the second elastic member 1215 and moves, so that the first pressing end 12141 abuts against and presses the driving portion 12121;

[0080] When the pressing member 1214 is released, the needle head 12123 at least partially extends out through the second opening 121421 under the elastic force of the first elastic member 1213 .

[0081] In this embodiment, the first pressing end of the pressing member is used to gradually approach, abut and press the driving part when the pressing member is pressed, so as to drive the striker to move in the first direction and compress the first elastic member. The second protective end of the pressing member is used to shield the needle head of the striker when there is no need to break the window, so as to protect the user. Specifically, the second elastic member biases the needle head to be retracted relative to the second opening, so that if the user does not over-press the pressing member, the needle head will not be exposed, and thus will not cause damage to the user. The second elastic member also biases the first pressing end to a state where there is a gap between the pressing member and the driving part, so as to ensure that when the user breaks the window, the pressing member needs to move a certain distance before the pressing member can abut the driving part and drive the driving part to move. In this way, when the first elastic member releases the elastic potential energy, the ejection speed of the striker is faster, and the striker can first break the glass, and then the pressing member is reset to the initial state (the second protective end shields the needle head of the striker in the initial state), so as to ensure that the striker can effectively break the glass.

[0082] When using the device disclosed in the present invention to break a window, the user can place the second protective end against the glass surface to be broken and press the lighting device. In this way, the second protective end is subjected to the reaction force provided by the glass and moves in the first direction, so that the first pressing end gradually approaches, abuts and presses the driving part, causing the striker to move and squeeze the first elastic part. When the squeezing reaches a certain degree, the user can cancel the pressing of the lighting device, so that the first elastic part can release its own elastic potential energy, causing the striker to pop out at a high speed, and the needle head of the striker hits the glass to break the glass; then, within a short time, the pressing part is reset to the initial state under the action of the second elastic part.

[0083] It should be noted that, in order to ensure that the striker can break the glass when the first elastic member releases its elastic potential energy, the moment when the top pressure member is completely reset needs to be later than the moment when the striker is completely ejected. This can be achieved by adjusting the elastic coefficient or compression amount of the first elastic member and the second elastic member and other parameters. Those skilled in the art can set them according to actual conditions, and this application does not make any specific limitations.

[0084] Optionally, the elastic coefficient of the first elastic member 1213 is greater than the elastic coefficient of the second elastic member 1215. In this way, it is helpful to ensure that the ejection speed of the striker is fast, and the top pressure member has not yet reset to the initial state when the striker breaks the glass, thereby improving the window breaking effect.

[0085] Optional, reference Figure 5The pressing member 1214 has a first through hole 12143, and the first through hole 12143 is connected to the first pressing end 12141 and the second opening 121421;

[0086] The needle head 12123 is at least partially located in the first through hole 12143 , one end of the second elastic member 1215 is installed in the first through hole 12143 , and the second elastic member 1215 is sleeved outside the needle head 12123 .

[0087] In this embodiment, the pressing member has a first through hole, which can guide the movement of the needle head so that it can be ejected from the second opening more smoothly. In addition, the first through hole can also encapsulate the second elastic member to improve the appearance of the device. The second elastic member is sleeved outside the needle head, that is, the needle head, the second elastic member and the pressing member are sleeved in sequence, which is conducive to reducing the volume of the device.

[0088] Optional, reference Figure 5 The second protection end 12142 has an elastic member installation structure 121422, and the outer wall of the needle head 12123 has an elastic member limiting structure 121231;

[0089] One end of the second elastic member 1215 is mounted on the elastic member mounting structure 121422 , and the other end abuts against the elastic member limiting structure 121231 .

[0090] In this embodiment, an elastic member installation structure and an elastic member limiting structure are respectively provided at the second protective end and the needle head, which can achieve stable limiting and installation of both ends of the second elastic member and ensure the working stability of the second elastic member.

[0091] Optional, reference Figure 5 The elastic member installation structure 121422 may be a convex ring structure located in the first through hole 12143, and the elastic member limiting structure 121231 may be a step structure. Optionally, the needle head 12123 at least partially extends into the convex ring structure.

[0092] Optionally, the first elastic member 1213 and the second elastic member 1215 are spring structures. The second elastic member 1215 is a variable diameter spring, and the diameter of one end of the spring that cooperates with the elastic member limiting structure is smaller than the diameter of one end that cooperates with the elastic member mounting structure, so that the two ends of the second elastic member can be connected to the needle head and the second protection end of different sizes respectively.

[0093] In some embodiments, reference Figure 5 The inner wall of the first accommodating cavity 12111 has a second sliding limiting structure 121111, and the pressing piece 1214 also includes a third sliding limiting structure 12144. The third sliding limiting structure 12144 and the second sliding limiting structure 121111 can slide relative to each other and can limit the pressing piece 1214 from escaping from the first accommodating cavity 12111.

[0094] In this embodiment, with the help of the second sliding limit structure and the third sliding limit structure, it can be ensured that the top pressure piece can slide relative to the window breaking main body, and at the same time the top pressure piece will not be separated from the window breaking main body, thereby ensuring the working stability of the window breaking assembly.

[0095] Optional, reference Figure 5 , one of the second sliding limiting structure 121111 and the third sliding limiting structure 12144 is a sliding groove, and the other of the second sliding limiting structure 121111 and the third sliding limiting structure 12144 is a sliding block. Figure 6 The above-mentioned slide groove can also be a through groove opened at the bottom.

[0096] In this embodiment, a simple implementation method of a sliding limit structure is provided, which has low cost and good stability. Those skilled in the art can also make adjustments according to needs, and this application will not describe it in detail.

[0097] In some embodiments, reference Figure 5 The driving portion 12121 includes at least one elastic arm 121211, and the elastic arm 121211 gradually extends radially outward in a direction from the mounting portion 12122 to the needle head 12123;

[0098] The first accommodating cavity 12111 has a protruding structure 121112;

[0099] When the driving portion 12121 is driven to move in the first direction, the elastic arm 121211 abuts against the protruding structure 121112 and is compressed radially inward.

[0100] In this embodiment, the driving part includes at least one elastic arm, and the driving part can add a thrust to the ejection of the striker on the basis of its original driving function. Specifically, when the driving part moves in the first direction, the elastic arm is pressed by the protruding structure and compressed radially inward. When the driving part is released, in addition to the first elastic member releasing its elastic potential energy, the elastic restoring force of the elastic arm will force the elastic arm to expand radially outward. This expansion process will further push the striker to be ejected in the opposite direction of the first direction, thereby increasing the impact force of the striker on the glass.

[0101] Optionally, the number of the elastic arms 121211 and the protruding structures 121112 are both two or more, and are arranged one-to-one. One end of the elastic arm 121211 away from the mounting portion 12122 is used to abut against the top pressing member 1214. Optionally, the elastic arm 121211 is a plastic part.

[0102] In some embodiments, reference Figure 6The multifunctional part 12 further includes a cutting knife assembly 122 . The cutting knife assembly 122 includes a cutting knife frame 1221 and a cutting knife 1222 . The cutting knife 1222 is installed on the cutting knife frame 1221 .

[0103] In this embodiment, the multifunctional portion is also integrated with a cutting knife assembly, so that the lighting device also has the function of cutting items such as seat belts, further expanding the use scenarios of the lighting device.

[0104] Optionally, the cutting knife assembly 122 is integrated with the window breaking assembly 121 (they can be integrally prepared or installed and connected as one) to further reduce the size of the device. Figure 6 As shown, the cutting blade holder 1221 is integrated with the window breaking body 1211 .

[0105] In some embodiments, reference Figure 3 The lighting unit 11 includes a control device 111, a light emitting element 112 and a lens assembly 113. The control device 111 is used to control the light emitting element 112 to switch between at least two light emitting modes. The lens assembly 113 is used to control the lighting unit 11 to switch between at least a floodlight mode and a spotlight mode.

[0106] In this embodiment, the light-emitting elements of the lighting unit have at least two light-emitting modes, and the lighting unit has at least two modes: a floodlight mode and a spotlight mode, so that the lighting modes of the lighting device are more diverse and can meet different usage requirements.

[0107] Optionally, the control device 111 is used to control the light emitting element 112 to switch between the following five light emitting modes: strong light, medium strong light, weak light, flashing, and alarm (SOS). Specifically, the switching of the light emitting mode (such as controlling the resistance value of the resistor in the path) can be achieved by pre-burning the corresponding control program in the control device. The above modes can fully meet the needs of seeing or asking for help in outdoor emergency scenarios.

[0108] Optionally, the light emitting element 112 may be a light emitting diode (LED), and the control device 111 may be implemented by integrating a corresponding control chip on a circuit board.

[0109] Optional, reference Figure 1-2 The lighting device further comprises a component installation and accommodating portion 13, and the component installation and accommodating portion 13 is used to accommodate a variety of components. Specifically, referring to Figure 3 The component mounting accommodation portion 13 has a second shell 131 , and various components are located in the second shell 131 .

[0110] Optional, reference Figure 1 and 3The component mounting and accommodating portion 13 has a button 132, which is mounted on the second housing 131 and at least partially exposed from the second housing 131. The button 132 is electrically connected to the control device 111 to send an electrical signal to the control device 111 when pressed. In this way, the user can actively control the light-emitting mode of the light-emitting element through the button 132 and the control device 111.

[0111] Optionally, the signal of long pressing the button 132 for a specific period of time can be set as a turn-on signal or an turn-off signal of the lighting unit. For example, when the user long presses the button 132 for 1.5 seconds, the light-emitting element of the lighting unit is turned on or off; the short press operation of the button 132 corresponds to a switching signal of the lighting mode. For example, each time the user short presses the button 132, the light-emitting element is controlled to switch to the next lighting mode.

[0112] Optional, reference Figure 3 The component installation and accommodating portion 13 further includes a key support frame 133 and a key fixing frame 134 .
