[0002] Concealed door handles are widely used as exterior and functional components in automobiles, which has placed higher demands on their design. They must be aesthetically pleasing, practical, and functional in various emergency situations. Currently, most handles offer an emergency opening mechanism, allowing entry via a mechanical key, in the event of a power outage. However, in situations where the door locks of a collision vehicle remain locked, the doors cannot be opened from the outside, hindering external rescue efforts. Summary of the Invention
[0003] In view of the shortcomings of the existing technology, the purpose of this invention is to provide a concealed door handle and method that can be used as a safety hammer. The handle can be easily removed and the handle integrates a counterweight, so it can be used as a safety hammer and meets the functional requirements of the handle.
[0004] To achieve the above objectives, the present invention is implemented through the following technical solution:
[0005] In a first aspect, embodiments of the present invention provide a concealed door handle that can be used as a safety hammer, including a base, a handle cover, and a handle. The disassembly port of the handle cover is limited by a limiting buckle of the handle. The base has a pin hole opened in opposite directions along the Z direction. The handle is engaged with the pin hole through a pin, and a torsion spring is sleeved on the pin. A counterweight is connected to the side of the handle facing the base.
[0006] The handle cover has multiple handle cover latches along the Y direction inside, and the handle has multiple handle latches along the Y direction inside; when the limiting latches are released from the handle cover, the handle cover can move a set distance along the Y direction so that the handle cover latches and the handle latches fit together, and at the same time the pin slides out of the pin hole under the action of the torsion spring.
[0007] As a further implementation, when the handle cover is limited by the limiting buckle, the handle cover buckle and the handle buckle have a set gap along the Y direction.
[0008] As a further implementation, both the handle cover latch and the handle latch are L-shaped structures, and they face opposite directions.
[0009] As a further implementation, a wedge-shaped block is also provided on the inner side of the handle cover, wherein the disassembly port is located near one end of the handle cover, and the wedge-shaped block is located near the other end of the handle cover.
[0010] As a further implementation, when the handle cover is limited by the limiting buckle, the head of the shaft pin abuts against the wedge block to maintain the torsion spring in a compressed state.
[0011] As a further implementation, when the limit latch is released from the handle cover, the handle cover moves toward the disassembly port.
[0012] As a further implementation, when the limit latch is released from the handle cover, the handle can be removed along the X direction.
[0013] As a further implementation, the head of the counterweight has a conical pointed structure.
[0014] Secondly, embodiments of the present invention also provide a method for using a concealed door handle that can be used as a safety hammer, including:
[0015] Use a tool to pry open the limit buckle in the handle to disengage the handle cover from the handle limit;
[0016] Move the handle cover along the Y direction until each handle cover latch and the corresponding handle latch are engaged;
[0017] The pin retracts towards the center under the reaction force of the torsion spring, causing the pin to slide out of the corresponding pin hole, and the handle can be removed along the X direction.
[0018] As a further implementation, the handle can be removed and used as a safety hammer with a counterweight.
[0019] The beneficial effects of this invention are as follows:
[0020] (1) The handle and handle cover of the present invention are limited by the limiting buckle in the installed state, and are connected to the base by the shaft pin and the torsion spring. When the handle needs to be removed, the limiting buckle can be lifted by a tool, and the handle cover can be moved in the horizontal direction. Under the reaction force of the torsion spring, the connection between the shaft pin and the base is released, so that the handle can be removed quickly. At the same time, the handle is equipped with a counterweight, which can act as a safety hammer and can be used for emergency purposes.
[0021] (2) The handle and handle cover of the present invention are provided with handle buckle and handle cover buckle respectively, which can play a guiding role in the sliding process of handle cover and limit the sliding distance, thereby realizing the separation of handle cover and handle.

[0033] Example 1:
[0034] In a typical embodiment of the present invention, such as Figures 1-8 As shown, a concealed door handle that can be used as a safety hammer is presented.
[0035] Since current door handles only provide emergency access when the vehicle is powered off, allowing entry via mechanical key, and in cases where the vehicle door locks are not unlocked after a collision, the doors cannot be opened from the outside, hindering external rescue efforts; therefore, this embodiment provides a concealed door handle that can function as a safety hammer. Through the structural design of the handle 2 and handle cover 1, the handle 2 can be quickly removed and used as a safety hammer, increasing the functionality of the door handle.
[0036] The above-mentioned concealed door handle will now be described in detail with reference to the accompanying drawings.
[0037] like Figure 1 As shown, in this embodiment, the horizontal direction of the handle and the door installation state is defined as the Y direction, the height direction of the handle is defined as the Z direction based on the Y direction, and the direction perpendicular to the door is defined as the X direction.
[0038] The concealed door handle of this embodiment includes components such as a base 3, a handle cover 1, and a handle 2. The handle cover 1 is located on the outside of the handle 2, and both the handle cover 1 and the handle 2 are mounted on the base 3.
[0039] Specifically, the base 3 has pin holes along the Z direction. For ease of description, the first pin hole 3-1 and the second pin hole 3-2 are used for distinction. The handle 2 has a through hole corresponding to the pin hole. The handle 2 and the base 3 are connected by inserting the first pin 4 and the second pin 6 into the corresponding pin hole.
[0040] like Figure 2 As shown, a first torsion spring 5 is sleeved on the outer side of the first axle pin 4, and a second torsion spring 7 is sleeved on the outer side of the second axle pin 6. The first torsion spring 5 and the second torsion spring 7 are respectively limited by the heads of the corresponding axle pins and are set in the through hole of the handle 2. When the handle is installed, the heads of the first axle pin 4 and the second axle pin 6 abut against the wedge blocks 1-6 in the handle cover 1 to fix the handle cover 1, the handle 2 and the base 3. At this time, the first torsion spring 5 and the second torsion spring 7 are in a compressed state.
[0041] like Figure 4 As shown, the cross-section of the wedge block 1-6 is wedge-shaped, protruding a certain height from the inner wall of the handle cover 1 and set near one end of the handle cover 1; a disassembly port 1-1 is provided on the side wall near the other end of the handle cover 1, and the disassembly port 1-1 is used to disassemble the handle by means of a tool.
[0042] Multiple handle cover clips are also installed on the inner side of the handle cover 1. The handle cover clips are used to cooperate with the handle clips in the handle 2. The number of handle cover clips can be set according to the actual installation requirements. In this embodiment, there are four handle cover clips, namely the first handle cover clip 1-2, the second handle cover clip 1-3, the third handle cover clip 1-4, and the fourth handle cover clip 1-5. The first handle cover clip 1-2 is located between one end of the handle cover 1 and the wedge block 1-6, and the fourth handle cover clip 1-5 is located between the other end of the handle cover 1 and the disassembly port 1-1.
[0043] like Figure 5As shown, the number of handle latches inside the handle 2 is the same as the handle cover latches, that is, there are first handle latch 2-2, second handle latch 2-3, third handle latch 2-4 and fourth handle latch 2-5. When the handle cover 1 and handle 2 are installed, the corresponding handle latches and handle cover latches are staggered by a certain distance along the Y direction so that the handle cover 1 can be moved when the pin is released from its limiting state.
[0044] In this embodiment, both the handle cover latch and the handle latch are L-shaped structures and face opposite directions, so that the handle cover 1 and the handle 2 can be effectively engaged after the handle cover 1 is moved.
[0045] Handle 2 is also equipped with a limit buckle 2-1, such as Figure 3 As shown, with the handle cover 1 and handle 2 installed, the limiting buckle 2-1 abuts against the disassembly port 1-1; when a tool is used to lift the limiting buckle 2-1, the limiting effect of the limiting buckle 2-1 on the handle cover 1 can be released. This tool can be a key or other flat tool.
[0046] After the limit buckle 2-1 is lifted, the handle cover 1 can be moved along... Figure 4 The slider moves a certain distance in the indicated direction. This distance is the gap between the handle cover latch and the handle latch, for example, this distance is set to 7mm; until the slider slides until the corresponding handle cover latch contacts the handle latch, i.e. Figure 6 In the state shown, the handle cover latch and the handle latch are engaged, effectively limiting the sliding distance. Thus, during the sliding process, the handle cover latch and the handle latch play a guiding and limiting role. The limitation between handle cover 1 and handle 2 by the limiting latch 2-1 is changed to the limitation by the handle cover latch and the handle latch. In both states, the effective cooperation between handle cover 1 and handle 2 can be guaranteed, making it easy for the two to disengage.
[0047] like Figure 7 As shown, while the handle cover 1 moves along the sliding direction, its internal wedge block 1-6 also slides simultaneously. At this time, the first shaft pin 4 and the second shaft pin 6 are retracted a certain distance, for example, 4mm, towards the center under the reaction force of the first torsion spring 5 and the second torsion spring 7, so that the first shaft pin 4 and the second shaft pin 6 slide out from the first shaft pin hole 3-1 and the second shaft pin hole 3-2 of the base 3. At this time, the heads of the first shaft pin 4 and the second shaft pin 6 abut against each other, and the handle 2 can be removed in the X direction, that is, removed in the direction away from the car door.
[0048] like Figure 8 As shown, a counterweight 8 is connected to the inner side of the handle 2. The head of the counterweight 8 is a conical pointed structure. The handle 2 and the counterweight 8 work together to break windows in an emergency, acting as a safety hammer to achieve the purpose of rapid rescue.
[0049] In this embodiment, the counterweight 8 is made of zinc alloy, and the handle 2 can withstand an external force of 1000N in any direction; of course, in other embodiments, the counterweight 8 can also be made of other metal materials, as long as the requirements for breaking windows can be met.
[0050] In this embodiment, the handle 2 is equipped with a limiting buckle 2-1 that engages with the disassembly port 1-1 of the handle cover 1. At the same time, multiple handle buckles are set to engage with the handle cover buckles. In the installed state of the handle 2, handle cover 1 and base 3, and after the handle cover 1 is moved a certain distance, the effective engagement of the handle cover 1 and handle 2 can be guaranteed, so that the handle 2 can be quickly disassembled under specific operating conditions (such as by lifting with a tool). In addition, the handle 2 is connected to a counterweight 8, which can be used for window breaking operations and acts as a safety hammer.
[0051] Example 2:
[0052] This embodiment provides a method for using a concealed door handle that can be used as a safety hammer. The concealed door handle adopts the structure described in Embodiment 1, specifically including:
[0053] Use a key or other flat tool to pry up the limiting buckle 2-1 in the handle 2 at the disassembly port 1-1 of the handle cover 1, so that the handle cover 1 is separated from the handle 2.
[0054] Move the handle cover 1 a certain distance along the Y direction until each handle cover buckle and the corresponding handle buckle are engaged; the wedge block 1-6 also slides at the same time. At this time, the first axle pin 4 and the second axle pin 6 are retracted a certain distance towards the center under the reaction force of the first torsion spring 5 and the second torsion spring 7, respectively, so that the first axle pin 4 and the second axle pin 6 slide out from the first axle pin hole 3-1 and the second axle pin hole 3-2 of the base 3, so that the heads of the first axle pin 4 and the second axle pin 6 abut against each other, and the handle 2 can be removed along the X direction, that is, removed in the direction away from the car door.
[0055] The handle 2, together with the counterweight 8, can easily break windows in emergencies, serving as a safety hammer.
[0056] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
