Technical Field
[0001] The utility model relates to the technical field of vehicle door handles, in particular to a retractable vehicle handle. Background Art
[0002] A Chinese patent application document with announcement number CN219993432U discloses a hidden car door handle, which includes a base and a handle. The base is provided with a receiving groove that can accommodate the extension and retraction of the handle. An active rod is connected to the end of the handle. A connecting rod mechanism and a driving component connected to the active rod are also provided in the base. When the active rod is flipped, the handle is driven to extend out of the receiving groove. A lock core structure for unlocking the locked door is provided in the receiving groove. A driven rod is provided between the handle and the lock core structure. When the handle is extended out of the receiving groove, the driven rod rotates a certain angle and is in a waiting state. When people pull the handle, the driven rod rotates a certain angle again to unlock the lock core structure. A resetting component for driving the lock core structure, the handle and the driven rod to reset is provided on the lock core structure. The hidden car door handle is widely used in trams.
[0003] In today's online car-hailing market, electric cars account for an increasingly larger proportion. From the perspective of the entire vehicle, door handles are the components that interact most with passengers besides the interior of the vehicle. If passengers carry infectious viruses, it is easy for the viruses to be left on the door handles when getting on and off the vehicle. The handles are usually stored in the storage slots and are difficult to clean. In addition, the existing hidden car door handles lack disinfection devices. If car owners want to disinfect, they can only do it manually, which is more troublesome. Utility Model Content
[0004] In view of the shortcoming that the existing hidden car door handles cannot be automatically disinfected, the purpose of the utility model is to provide a retractable car handle that can be automatically disinfected after being stored.
[0005] In order to solve the above technical problems, the utility model is solved by the following technical solutions:
[0006] A retractable automobile handle comprises a base and a handle, wherein the base is provided with a receiving groove for the handle to be retracted, an ultraviolet sterilization lamp is provided in the receiving groove, a switch mechanism is provided between the base and the handle, the switch mechanism and the ultraviolet sterilization lamp are connected by electric wires, the switch mechanism comprises a first switch provided at the bottom of the receiving groove and a first touch plate provided on the handle, and when the handle is fully retracted, the first touch plate abuts against the first switch to energize the ultraviolet sterilization lamp.
[0007] By adopting the above scheme, when the handle is retracted into the accommodating groove, the first touch plate is against the first switch, and the ultraviolet sterilization lamp is turned on for disinfection; when the car door handle is extended, the first touch plate is away from the first switch, the first switch is reset, and the ultraviolet sterilization lamp is turned off. Since the most frequently used position of the car door handle is the side of the handle facing the accommodating groove, the ultraviolet sterilization lamp is set in the accommodating groove to fully irradiate the inner side of the handle, and the disinfection effect is good. Compared with the prior art, the handle in this scheme can automatically turn on and off the ultraviolet sterilization lamp for disinfection when it is extended and retracted, and the owner does not need to manually disinfect, which is very convenient.
[0008] Preferably, a pair of contacts are provided between the wires connecting the switch mechanism and the ultraviolet sterilization lamp, and a trigger mechanism is provided between the handle and the base for connecting the contacts when the handle is extended and pulled, a retaining component for keeping the trigger mechanism and the contacts connected, and a delay mechanism is provided for being triggered and delayed in starting when the handle is retracted, and the connection between the trigger mechanism and the contacts is disconnected after the delay of the delay mechanism ends.
[0009] By adopting the above scheme, when the handle is extended, the contacts can be connected to close the circuit of the ultraviolet sterilization lamp only after the handle is pulled. The ultraviolet sterilization lamp will not be powered after the handle that has not been pulled is retracted, which can save energy. Considering that the area of the door handle is small, the time required for disinfection will not be long under sufficient irradiation, so it will be a waste of energy to turn on the ultraviolet sterilization lamp all the time when the handle is retracted into the receiving groove. The delay mechanism in this scheme will disconnect the connection between the trigger mechanism and the contacts after the delay ends, that is, the ultraviolet sterilization lamp will only be turned on for disinfection within a period of time after the handle is retracted, which can further save energy.
[0010] Preferably, the trigger mechanism includes a second touch plate capable of connecting to or moving away from the contact, a through hole opened on the inner wall of the accommodating groove, and a push rod guided and moved along the through hole and connected to the second touch plate, one end of the push rod passes through the accommodating groove, and when the handle is pulled, the handle abuts against the push rod and drives the second touch plate to approach the contact to connect the contacts, and the second touch plate is made of conductive material.
[0011] Preferably, the retaining component includes a metal strip fixedly installed in the base and attracted by a magnet, and a permanent magnet installed on the second touch plate. When the second touch plate is connected to the contact point, the permanent magnet and the metal strip are attracted to keep the second touch plate in the above-mentioned connection state. An insulating mounting block is arranged between the permanent magnet and the second touch plate.
[0012] Preferably, the delay mechanism includes a delay relay arranged in the base, a coil wound on the metal strip and a second switch arranged at the bottom of the accommodating groove. The delay relay, the coil and the second switch are electrically connected. When the handle is retracted, the first touch plate abuts against the second switch to energize the delay relay for timing. After the timing is completed, the coil is energized and cooperates with the metal strip to form an electromagnet, and the opposite ends of the electromagnet and the permanent magnet have the same poles.
[0013] By adopting the above scheme, after the handle is extended out of the accommodating groove, people can pull the handle to drive the push rod to move, drive the second touch plate to connect the contacts, and at the same time the permanent magnet will be adsorbed on the metal strip to restrict the second touch plate from being separated from the contacts. After the handle is retracted, the ultraviolet sterilization lamp is turned on, and at the same time the second switch is triggered to start timing the delay relay. After the timing ends, the coil is energized to turn the metal strip into an electromagnet, and a repulsive force is generated between the electromagnet and the permanent magnet, driving the second touch plate away from the contacts to disconnect, and the ultraviolet lamp is turned off.
[0014] Preferably, an elastic retaining member is provided between the second trigger plate and the base to prevent the second trigger plate from moving due to inertia and thus connecting with the contact point.
[0015] Preferably, the elastic retaining member is a tension spring with one end fixed to the base and the other end fixed to the second trigger plate, and the tension of the tension spring is smaller than the magnetic attraction of the permanent magnet.
[0016] By adopting the above solution, the tension spring can reduce the influence of the inertia generated when the vehicle moves on the second touch plate, and reduce the occurrence of the second touch plate being displaced and the contact points being connected due to the inertia when starting or braking.
[0017] Preferably, the ultraviolet sterilization lamp is arranged on the inner wall of the accommodating groove in the form of a light belt.
[0018] With the above solution, since the area of the door handle is small, the power and time required for disinfection will not be long, and the ultraviolet sterilization lamp in the form of a light strip can evenly irradiate the surface of the door handle.
[0019] The utility model has significant technical effects due to the adoption of the above technical solutions:
[0020] 1. When the handle is retracted into the accommodating groove, the first touch plate is against the first switch, and the ultraviolet sterilization lamp is turned on for disinfection. When the door handle is extended, the first touch plate is away from the first switch, the first switch is reset, and the ultraviolet sterilization lamp is turned off. Compared with the prior art, the handle in this solution can automatically turn on and off the ultraviolet sterilization lamp for disinfection when it is extended and retracted, and the owner does not need to disinfect manually, which is very convenient.
[0021] 2. When the handle is extended, the contacts can only be connected after the handle is pulled to close the circuit of the ultraviolet sterilization lamp. After the handle that has not been pulled is retracted, the ultraviolet sterilization lamp will not be powered, which can save energy. Considering that the area of the door handle is small, the time required for disinfection will not be long under sufficient irradiation, so it will be a waste of energy to turn on the ultraviolet sterilization lamp all the time when the handle is retracted into the receiving groove. The delay mechanism in this solution will disconnect the connection between the trigger mechanism and the contacts after the delay ends, that is, the ultraviolet sterilization lamp will only be turned on for disinfection within a period of time after the handle is retracted, which can further save energy.

DETAILED DESCRIPTION
[0035] The utility model is further described in detail below in conjunction with the accompanying drawings and embodiments.
[0036] Example
[0037] A retractable car handle, according to Figures 1-2 As shown, it includes a base 1 and a handle 2. The base 1 is provided with a receiving groove 3 for the handle 2 to be extended and retracted. The receiving groove 3 is provided with an ultraviolet sterilization lamp 4. Figure 2 As shown, in this embodiment, the ultraviolet sterilization lamp 4 is arranged in the form of a light belt around the inner wall of the accommodating groove 3. A switch mechanism is arranged between the base 1 and the handle 2. The switch mechanism is connected to the ultraviolet sterilization lamp 4 by an electric wire. Figure 3 , Figure 5 or Figure 7 As shown, the switch mechanism includes a first switch 5 disposed at the bottom of the receiving groove 3 and a first touch plate 6 disposed on the handle 2. When the handle 2 is fully retracted, the first touch plate 6 abuts against the first switch 5 to energize the ultraviolet sterilization lamp 4.
[0038] according to Figure 6 As shown, a pair of contacts 7 are provided between the wires connecting the switch mechanism and the ultraviolet sterilization lamp 4, and a trigger mechanism is provided between the handle 2 and the base 1 to connect the contacts 7 when the handle 2 is extended and pulled. Figure 3 to Figure 6 As shown, the trigger mechanism includes a second touch plate 8 that can be connected to or away from the contact 7. A through hole 9 is opened on the inner wall of the accommodating groove 3. A push rod 10 is provided in the through hole 9 for guiding movement. The push rod 10 is connected to the second touch plate 8. One end of the push rod 10 passes through the accommodating groove 3. When the handle 2 is pulled, the handle 2 abuts against the push rod 10 and drives the second touch plate 8 to approach the contact 7 to connect the contact 7. The second touch plate 8 is made of conductive material. In this embodiment, the second touch plate 8 is a metal sheet with good conductivity. A holding component that keeps the contact 7 and the second touch plate 8 connected is also provided between the handle 2 and the base 1. Figure 4 or Figure 6As shown, the holding component includes a metal strip 11 fixedly arranged in the base 1 and attracted by a magnet, and a permanent magnet 12 is arranged on the second touch plate 8. When the second touch plate 8 is connected to the contact point 7, the permanent magnet 12 and the metal strip 11 are attracted to keep the second touch plate 8 connected to the contact point 7. An insulating mounting block 13 is arranged between the permanent magnet 12 and the second touch plate 8. In this solution, the insulating mounting block 13 is a rubber sleeve fixed on the touch plate, and the permanent magnet 12 is fixed in the rubber sleeve; according to Figure 4 or Figure 6 As shown, a time delay relay 14 is also provided in the base 1, a coil 15 is wound on the metal strip 11, a second switch 16 is provided at the bottom of the accommodating groove 3, and the time delay relay 14, the coil 15 and the second switch 16 are electrically connected. When the handle 2 is retracted, the first touch plate 6 abuts against the second switch 16 to energize the time delay relay 14 and start timing. After the timing is completed, the coil 15 is energized and cooperates with the metal strip 11 to form an electromagnet, and the opposite ends of the electromagnet and the permanent magnet 12 are of the same pole.
[0039] according to Figure 6 As shown, a tension spring 17 is provided between the second touch plate 8 and the base 1, and the two ends of the tension spring 17 are respectively fixed to the second touch plate 8 and the base 1. The tension of the tension spring 17 is smaller than the magnetic attraction of the permanent magnet 12. The tension spring 17 can reduce the influence of the inertia generated during the movement of the vehicle on the second touch plate 8, and reduce the occurrence of the displacement of the second touch plate 8 and the connection of the contact 7 due to the inertia during starting or braking.
[0040] Combined with the above structure, reference Figures 1 to 12 It can be seen that the start and stop process of the ultraviolet disinfection function of a retractable car handle 2 in this solution is described as follows:
[0041] After the handle 2 extends out of the accommodating groove 3, people pull the handle 2 to drive the second touch plate 8 to connect the contact 7, and at the same time the permanent magnet 12 attracts the metal strip 11 to keep the second touch plate 8 connected to the contact 7. When the handle 2 is retracted into the accommodating groove 3, the first touch plate 6 triggers the first switch 5 and the second switch 16 at the same time, and the ultraviolet sterilization lamp 4 and the delay relay 14 are started at the same time. During the timing of the delay relay 14, the ultraviolet sterilization lamp 4 disinfects the surface of the handle 2. When the timing is over, the coil 15 wound on the metal strip 11 is energized, and the metal strip 11 becomes an electromagnet. At this time, the permanent magnet 12 is affected by the repulsive force and drives the second touch plate 8 away from the contact 7. At this time, the ultraviolet disinfection lamp loses power and turns off.
[0042] In the present embodiment, a retractable car handle is provided. When the handle 2 is extended, the contact 7 can be connected to close the circuit of the ultraviolet sterilization lamp 4 only after the handle 2 is pulled. The ultraviolet sterilization lamp 4 will not be powered after the unpulled handle 2 is retracted, thereby saving energy. Considering that the area of the door handle 2 is small, the time required for disinfection will not be long under sufficient irradiation. Therefore, it will be a waste of energy to turn on the ultraviolet sterilization lamp 4 all the way when the handle 2 is retracted into the accommodating groove 3. The delay mechanism in the present solution will disconnect the connection between the trigger mechanism and the contact 7 after the delay ends, that is, the ultraviolet sterilization lamp 4 will only be turned on for disinfection within a period of time after the handle 2 is retracted, thereby further saving energy.
[0043] Finally, it should be noted that the above description is only a preferred embodiment of the utility model and is not intended to limit the utility model. Although the utility model is described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions recorded in the above embodiments or replace some of the technical features therein with equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
