Description

Technical Field

[0001] This utility model relates to the technical field of automotive parts, and in particular to a door handle and handle assembly with dot matrix lights. Background Technology

[0002] With the continuous development of automotive intelligence and exterior design, users' requirements for the functionality, aesthetics, and user experience of car door handles are constantly increasing, and the limitations of traditional car door handle structures are gradually becoming apparent.

[0003] Current illuminated car door handles generally employ a design where the light source is positioned vertically opposite the light-emitting surface. The light source is directly mounted behind the light-emitting area, and the light is emitted directly along the direction perpendicular to the light-emitting surface. This structure has significant drawbacks: Firstly, the stacking of the light source and the light-emitting surface along the thickness direction requires a large vertical space, increasing the overall thickness of the door handle. This affects the streamlined design and makes it difficult to adapt to the limited installation space inside the doors of some car models, restricting the design flexibility of the handle structure. Secondly, the direct light emission method easily leads to uneven light output. The light spot of a single light source is directly exposed, making it impossible to form a uniform and soft lighting effect. To achieve a dot matrix lighting effect, the light source needs to be independently arranged for each dot matrix hole, significantly increasing production costs and structural complexity. At the same time, heat dissipation issues further exacerbate the difficulty of structural design.

[0004] Meanwhile, regarding the operational comfort of the handles, existing door handle unlocking mechanisms generally lack a clear segmented travel design. There is no obvious tactile distinction between the electronic and mechanical unlocking processes, making it difficult for users to clearly perceive the current unlocking stage. This can easily lead to insufficient pull travel resulting in unlocking failure, or excessive pull causing structural damage. Furthermore, the lack of segmented resistance constraints during the rotation of the control lever not only results in a vague operational feel but also causes uneven force distribution during use. Over time, this can lead to structural fatigue, unlocking sticking, and other problems, affecting the reliability and lifespan of the door handles. Utility Model Content

[0005] To address the aforementioned problems in the existing technology, this utility model provides a door handle and handle assembly with dot matrix lights, which optimizes the lighting effect, reduces the structural thickness, and improves the feedback of the unlocking operation and the structural durability.

[0006] The above-mentioned problems of this utility model are solved by the following technical solution:

[0007] A door handle with a dot matrix light includes a handle housing and a frame that are closed to each other to form an assembly cavity, and a light-emitting component disposed in the assembly cavity. The handle housing has a light-emitting area formed on it, and the light-emitting component is disposed inside the light-emitting area and provides illumination to the light-emitting area.

[0008] The light-emitting area is formed with multiple light-transmitting units arranged in an array, and the light-emitting component is constructed with a light-emitting surface, the projection surface of the light-emitting surface and the projection surface of the light-emitting area coincide.

[0009] The light-emitting component includes a light source and a light guide group. The light source is located on the side of the light guide group. Light is emitted from the light source and incident laterally into the light guide group to provide illumination to the light-emitting surface.

[0010] A further provision of the above technical solution is that the light-emitting area is covered with a light-transmitting film.

[0011] A further configuration of the above technical solution is as follows: the light guide group includes a light guide plate and a light emission plate arranged in sequence in a direction perpendicular to the light emission surface, and the light source is located on the side of the light guide plate.

[0012] A further provision of the above technical solution is that the light-emitting component also includes a module frame, the module frame having a light guide groove inside that accommodates a light guide group, a PCB board being provided at the bottom of the light guide groove, and the light guide group and the light source being disposed on the PCB board.

[0013] The upper opening of the light guide groove exposes the light-emitting surface.

[0014] A further provision of the above technical solution is that: a receiving groove for accommodating the light-emitting component is formed on the skeleton, and the receiving groove is located below the light-emitting area.

[0015] This utility model also discloses a handle assembly, including the above-mentioned car door handle, and also includes a base fixed on the car door sheet metal, and a control lever, the control lever being used to activate the electric unlocking module and / or mechanical lock module of the car door;

[0016] The control lever is rotatably connected to the base via a pin; a drive arm extends from one end of the frame, passes through the base, and is connected to the control lever in a transmission manner, thereby driving the control lever to rotate.

[0017] A two-section arm assembly is also connected to the base. The two-section arm assembly acts on the control rod and applies a preload force to the control rod to prevent it from rotating and unlocking.

[0018] A further feature of the above technical solution is that the control lever has an electronic unlocking stroke and a mechanical unlocking stroke along the rotational opening direction;

[0019] During the electronic unlocking process, the control lever activates a micro switch to unlock the car door;

[0020] During the mechanical unlocking process, the control lever pulls the unlocking cord to unlock the car door;

[0021] The two-section arm assembly preloads the control lever during the mechanical unlocking stroke.

[0022] A further provision of the above technical solution is that the two-section arm assembly includes two lever arms that abut against the control lever, and a lever arm torsion spring that keeps the two lever arms in the abutment position.

[0023] A pressure bar is formed on the two-section lever arm, and the pressure bar extends to the side of the control rod, forming a gap with the control rod;

[0024] During the mechanical unlocking stroke, the pressure rod and the control rod abut against each other.

[0025] A further provision of the above technical solution is that: a pushing part is formed on the control rod, and during the mechanical unlocking stroke, the pushing part and the pressure rod abut against each other;

[0026] A retaining block is provided on the base, which abuts against the two-stage lever arm, keeping the pressure rod in a position where it is in a free-falling position relative to the control lever during the electronic unlocking stroke.

[0027] A further provision of the above technical solution is that a pull plate is formed on the drive arm, and a pull rod that can be pulled by the pull plate is provided on the control rod.

[0028] Compared with the prior art, the present invention has the following advantages:

[0029] 1. The light source adopts a parallel light-inlet form where the incident light and the light-outlet surface are parallel. The light source enters from the side of the light-outlet surface, avoiding the problem of uneven light output caused by direct light source on the light-outlet surface. At the same time, there is no need to stack light sources directly below the light-outlet surface, which greatly reduces the size of the handle in the thickness direction and is more suitable for the installation space of the car door.

[0030] 2. By shielding the other surfaces of the light guide assembly and exposing only the light-emitting surface, the light reaching the light-emitting surface is evenly distributed. Combined with the array of light-transmitting units, a complete and uniformly bright dot matrix light visual effect can be presented in the light-emitting area, avoiding the problem of single light spots being exposed.

[0031] 3. The surface of the light-emitting area is covered with a light-transmitting film, which can prevent water stains and dust from entering the assembly cavity without affecting the light transmission; the light-emitting component adopts a modular design, which can be pre-assembled and then assembled into the receiving slot of the frame, which simplifies the assembly process and facilitates later maintenance and replacement.

[0032] 4. By applying a preload to the control lever during the mechanical unlocking stroke through the two-stage arm assembly, the unlocking stroke is clearly divided into two segments: electronic unlocking and mechanical unlocking. The two-stage arm assembly forms a constraint limit on the control lever during the unlocking rotation, realizing segmented force on the control lever during the electronic unlocking stroke and the mechanical unlocking stroke. At the same time, the user can clearly perceive the current unlocking stage through the operating feel, greatly improving the operating quality and user experience. Attached Figure Description

[0049] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.

[0050] like Figure 1-9 As shown in the following embodiments, a door handle with a dot matrix light and a handle assembly are disclosed. Example 1

[0051] Specific reference Figure 1 As shown, a door handle with a dot matrix light includes a handle housing 100 and a frame 200 that are closed to each other to form an assembly cavity, and a light-emitting component 300 disposed in the assembly cavity. The handle housing has a light-emitting area 101 formed on it, and the light-emitting component 300 is disposed inside the light-emitting area 101 and provides illumination to the light-emitting area 101.

[0052] The handle housing 100 is configured as a housing with a groove structure, and the opening of the groove structure faces the side of the car door. The frame 200 seals the opening, thereby closing the groove structure and forming an assembly cavity. At the same time, the middle part of the frame 200 is configured as a concave structure away from the car door, so that a handle groove for a person to reach into is formed between the handle and the car door.

[0053] The light-emitting region 101 is formed with a plurality of light-transmitting units 101.1 arranged in an array, and the light-emitting component 300 is constructed with a light-emitting surface 322.1. The projection surface of the light-emitting surface 322.1 coincides with the projection surface of the light-emitting region 101, thereby illuminating the light-emitting region 101.

[0054] The light-transmitting unit 101.1 is a small hole that runs through the handle housing. The light-emitting surface 322.1 is located inside the assembly cavity and is arranged perpendicular to or at an angle to the through direction of the light-transmitting unit 101.1, so that the light from the light-emitting surface 322.1 can pass through the light-transmitting unit 101.1 and present a dot matrix light visual effect consistent with the layout structure of the light-transmitting unit 101.1.

[0055] Preferably, the projection of the light-emitting surface 322.1 onto the light-emitting area 101 can completely cover all the light-transmitting units 101.1, thereby ensuring that all the light-transmitting units 101.1 can observe the lighting effect, so as to form a complete and uniformly bright dot matrix light effect.

[0056] The light-emitting component 300 includes a light source 310 and a light guide group 320. The light source 310 is located on the side of the light guide group 320. Light is emitted from the light source 310 and incident laterally into the light guide group 320, providing illumination to the light surface 322.1.

[0057] As a preferred form of incident light, in this embodiment, the light source 310 enters the light guide group 320 along an incident direction parallel to the light emitting surface 322.1, and then exits from the light emitting surface 322.1.

[0058] Based on the above arrangement of incident directions, the light-emitting surface 322.1 has a relatively uniform illumination effect.

[0059] Preferably, in this embodiment, the light-transmitting unit 101.1 can be arranged in an array structure such as a rectangular array or a circular array.

[0060] As a further preferred embodiment, the light-emitting region 101 is covered with a light-transmitting film.

[0061] Specifically, the light-emitting area 101 is preferably set on a relatively flat surface on the handle housing. Multiple light-transmitting units 101.1 are distributed on this surface to present a dot matrix visual effect. Furthermore, a light-transmitting film is covered on this surface to seal the openings of the light-transmitting units 101.1 on the outer surface of the handle housing 100, preventing external water stains or dust from entering the assembly cavity through the light-transmitting units 101.1. At the same time, the light-transmitting film can transmit light without affecting the presentation of the dot matrix light.

[0062] As a specific embodiment of the light guide group 320, in this embodiment, the light guide group 320 includes a light guide plate 321 and a light emission plate 322 stacked in a direction perpendicular to the light emission surface 322.1, and the light source 310 is located on the side of the light guide plate 321.

[0063] Specific reference Figure 2 and Figure 3 As shown, both the light guide plate 321 and the light emitting plate 322 are configured as plate structures and are stacked in the assembly cavity. The light emitting surface 322.1 is located on the upper end surface of the light emitting plate 322, below the light transmission unit 101.1, and the light guide plate 321 is located below the light emitting plate 322.

[0064] The light source 310 is arranged on the side of the light guide plate 321. Light is incident from the side of the light guide plate 321. After passing through the light guide plate 321, the light is emitted to the light emitting plate 322 and finally emitted uniformly from the light emitting surface 322.1 of the light emitting plate 322, presenting a uniform brightness illumination effect on the light emitting surface 322.1.

[0065] Compared to placing the light source 310 below the light-emitting surface 322.1 and incident perpendicularly to the light-emitting surface 322.1, this embodiment adopts a side-entry light method. The light incident into the light guide plate 321 is parallel to the light-emitting surface 322.1, avoiding uneven illumination caused by direct light emanating from the light-emitting surface 322.1. At the same time, this side-entry light arrangement can also reduce the size of the handle in the thickness direction, avoiding the increase in the overall thickness of the handle due to the vertical stacking of the light source 310, and better adapting to the installation space of the car door.

[0066] As a specific embodiment of the light-emitting component 300, in this embodiment, the light-emitting component 300 further includes a module frame 330. The module frame 330 has a light guide groove 331 inside that accommodates the light guide group 320. A PCB board 340 is provided at the bottom of the light guide groove 331. The light guide group 320 and the light source 310 are disposed on the PCB board 340.

[0067] The upper opening of the light guide groove 331 exposes the light-emitting surface 322.1.

[0068] Specific reference Figure 1 and Figure 3 As shown, the module frame 330 includes at least a side enclosure that forms a light guide groove 331. The PCB board 340, the light guide plate 321, and the light emission plate 322 are stacked and arranged in the light guide groove 331. The light source 310 is mounted on the PCB board 340 and is located on the side of the light guide plate 321. The light-emitting surface of the light source 310 faces the side of the light emission plate 322.

[0069] The side structure of the module frame 330 shields the side end face of the light guide group 320, preventing light from emanating from the side end face, while only the light emanating surface 322.1 is exposed on the opening side of the light guide groove 331 to emit light.

[0070] As a preferred embodiment of the module frame 330, the PCB board 340 can be fixed to the bottom of the light guide groove 331 as a base plate, or a separate base plate can be set to form a groove structure with only an opening at the top.

[0071] The side-mounted light source allows the light source 310 to be hidden inside the side of the light guide groove 331, without occupying the front space of the light-emitting plate 322 in the light-emitting direction. Therefore, the light-emitting plate 322 can achieve the effect of complete and uniform light emission from the entire front.

[0072] As one way of installing the light-emitting component 300, in this embodiment, the frame 200 is formed with a receiving groove 211 for accommodating the light-emitting component 300, and the receiving groove 211 is located below the light-emitting area 101.

[0073] Specific reference Figure 1 As shown, the frame 200 has an insertion part 210 extending towards the handle housing 100, which is used to insert into the handle housing 100 to form a stable assembly. The insertion part 210 has a receiving groove 211 formed on it. When the insertion part 210 enters the handle housing 100, the receiving groove 211 is located below the light-emitting area 101. The light-emitting component 300 located in the receiving groove 211 provides illumination to the light-emitting area 101 and transmits light.

[0074] Based on the above-mentioned modular framework 330, the light-emitting component 300 is modularized, which not only facilitates the pre-assembly of the light-emitting component 300 in advance, but also allows it to be directly assembled into the receiving slot 211 of the frame 200, simplifying the assembly process of the door handle. At the same time, the modular structure also facilitates the maintenance and replacement of the light-emitting component 300 in the later stage. Example 2

[0075] A handle assembly includes the door handle described in Embodiment 1, and further includes a base 400 fixed to the door sheet metal, and a control lever 500, the control lever 500 being used to activate the door's electric unlocking module and / or mechanical lock module;

[0076] The control lever 500 is rotatably connected to the base 400 via a pin 1; a drive arm 220 extends from one end of the frame 200, the drive arm 220 passes through the base 400 and is connected to the control lever 500 in a transmission manner, thereby driving the control lever 500 to rotate, and the control lever 500 unlocks the car door during the rotation process.

[0077] When a person reaches into the handle slot to pull the door handle, the drive arm 220 moves outward and pulls the control lever 500. When the control lever 500 rotates, it activates the mechanical lock module or the electric unlocking module.

[0078] A two-section arm assembly 600 is also connected to the base 400. The two-section arm assembly 600 acts on the control rod 500 and applies a preload force to the control rod 500 to prevent it from rotating and unlocking.

[0079] As a specific implementation of the pre-tightening force, in this embodiment, the control lever 500 has an electronic unlocking stroke and a mechanical unlocking stroke along the rotational opening direction;

[0080] During the electronic unlocking process, the control lever 500 activates the micro switch 2 to unlock the car door;

[0081] During the mechanical unlocking process, the control lever 500 pulls the unlocking rope 3 to unlock the car door;

[0082] The two-section arm assembly 600 pre-tensions the control lever 500 during the mechanical unlocking stroke.

[0083] Specific reference Figure 4 and Figure 5 As shown, a micro switch 2 is installed on the base 400. The micro switch 2 is connected to the electric unlocking module inside the vehicle. When the user pulls the door handle, the door handle drives the control lever 500 to rotate. During the rotation, the control lever 500 activates the micro switch 2 to electrically unlock the door. When the electric unlocking module fails, the user continues to pull the door handle, causing the control lever 500 to continue rotating into the mechanical unlocking stroke. At this time, the two-stage arm assembly 600 and the control lever 500 abut against each other, applying a preload force to the control lever 500 to resist its rotation. The user needs to apply a greater pulling force to the door handle to drive the control lever 500 to rotate. When the control lever 500 rotates, it pulls the unlocking rope 3, causing the door to mechanically unlock.

[0084] In this embodiment, the electronic unlocking module and the mechanical unlocking module are consistent with the unlocking method of the car door in the prior art, and will not be described in detail here.

[0085] Based on the above settings, during normal use, only the electric unlocking module needs to be activated to unlock the car door. The mechanical unlocking module is only activated when the electric unlocking module fails. The two-stage arm assembly 600 constrains and limits the rotation of the control lever 500. At the same time, it provides segmented force to the control lever 500, giving the user clear travel feedback. This allows the user to clearly perceive which stage of unlocking is currently in, improving the quality of operation and the user experience.

[0086] As a specific embodiment of the two-section arm assembly 600, in this embodiment, the two-section arm assembly 600 includes a two-section lever arm 620 that abuts against the control rod 500, and a lever arm torsion spring 630 that keeps the two-section lever arm 620 in the abutting position.

[0087] A pressure rod 621 is formed on the two-section lever arm 620. The pressure rod 621 extends to the side of the control rod 500 and forms a gap with the control rod 500.

[0088] During the mechanical unlocking stroke, the pressure rod 621 and the control rod 500 abut against each other.

[0089] Specific reference Figure 4 and Figure 6As shown, the lever pin 610 for connecting the two-stage lever arm 620 and the pin 1 for connecting the control lever 500 are arranged in parallel, that is, the pin 1 of the two-stage lever arm 620 and the control lever 500 are parallel. A pressure rod 621 extends from the two-stage lever arm 620 toward the control lever 500. The pressure rod 621 is located on the rotation unlocking path of the control lever 500. When the control lever 500 rotates to the end of the electronic unlocking stroke, the pressure rod 621 and the control lever 500 abut against each other, applying pressure to the control lever 500 and hindering the rotation of the control lever 500.

[0090] Meanwhile, the lever arm torsion spring 630 is mounted on the lever arm pin 610 and located inside the second lever arm 620. Its torsion feet abut against the base 400 and the second lever arm 620 respectively, so that the second lever arm 620 is kept in the abutment position.

[0091] As a preferred arrangement of the lever arm torsion spring 630, the two-section lever arm 620 is provided with a torsion spring groove 622. The torsion spring groove 622 extends towards the pressure rod 621 to form a torsion foot groove 621.1. When the lever arm torsion spring 630 is installed in the torsion spring groove 622, the torsion foot extends into the torsion foot groove 621.1, directly applying torsional force to the pressure rod 621.

[0092] Preferably, in this embodiment, the control lever 500 is formed with a push part 501, and during the mechanical unlocking stroke, the push part 501 and the pressure rod 621 abut against each other;

[0093] A retaining block 410 is provided on the base 400. The retaining block 410 abuts against the two-stage lever arm 620, keeping the pressure rod 621 in a position of being in the air relative to the control rod 500 during the electronic unlocking stroke.

[0094] Specific reference Figure 7 As shown, the base 400 has a transfer groove 401 formed on it for accommodating and transferring the two-stage lever arm 620. The transfer groove 401 opens towards the control rod 500, and a retaining block 410 is formed on the groove edge of the transfer groove 401. Simultaneously, an abutment block 623 is provided on the two-stage lever arm 620 corresponding to the position of the retaining block 410, and the end faces of the abutment block 623 and the retaining block 410 form surface contact. When the two-stage lever arm 620 is not in use, due to the action of the lever arm torsion spring 630 and the retaining block 410, the abutment block 623 and the retaining block 410 abut against each other. At this time, there is a gap between the pressure rod 621 and the control rod 500, and the control rod 500 is not subjected to the force of the pressure rod 621 when rotating.

[0095] When the door handle is pulled by an external force, the control lever 500 rotates. The pusher portion 501 on the control lever 500 rotates towards the pressure lever 621, gradually approaching it until it makes contact with the pressure lever 621. At this point, the control lever 500 has rotated to the end of its electronic unlocking stroke. (See attached diagram for details.) Figure 8 As shown.

[0096] When the handle is pulled further into the mechanical unlocking stroke, the push part 501 on the control lever 500 generates a pushing force on the pressure rod 621, pushing the pressure rod 621 toward the side away from the control lever 500. At the same time, the pressure rod 621 generates pressure on the push part 501, which is the preload force of the second-stage lever arm 620 on the control lever 500.

[0097] During the mechanical unlocking process, the door handle is continuously pulled, which drives the control lever 500 to rotate continuously. The push part 501 rotates synchronously with the control lever 500. During the rotation, the push rod 621 is driven to push the push rod 621 outward. At the same time, the abutment block 623 and the retaining block 410 separate.

[0098] Specific reference Figure 9 As shown, in a preferred embodiment, the push portion 501 is configured as a protruding structure formed on the surface of the control rod 500.

[0099] In this embodiment, as a specific implementation of the drive structure of the door handle to the control lever 500, the drive arm 220 is provided with a pull plate 221, and the control lever 500 is provided with a pull rod 510 that can be pulled by the pull plate 221.

[0100] Specific reference Figure 5 As shown, the drive arm 220 is an extension formed on the frame 200, extending through the base 400 to the back of the base 400. A pull plate 221 extends from the end of the drive arm 220 towards the control rod 500. A pull rod 510 is provided on the control rod 500 towards the pull plate 221. Both ends of the pull rod 510 are formed on the control rod 500 through connecting sections, thus creating a gap between the pull rod 510 and the outer wall of the control rod 500. When the pull plate 221 is located on the side of the pull rod 510, the end of the pull plate 221 will not contact the control rod 500 and generate friction. The pull rod 510 is located between the pull plate 221 and the base 400. When the pull plate 221 moves towards the base 400 along with the door handle, the pull rod 510 is also pulled synchronously, causing the control rod 500 to rotate.

[0101] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present utility model.
