In the current automobile industry, in order to facilitate users to open and close doors, car remote controls are equipped. The remote control is equipped with at least two functions, unlocking and locking, which are used to send corresponding unlocking and locking signals to the car to realize remote control of opening and closing doors and other related actions, which provides convenience for users.

[0003] Generally speaking, a car remote control is usually carried by a user, and in order to allow the user to carry the car remote control, the car remote control needs to be miniaturized. Although the miniaturization of the car remote control makes the volume smaller, it also requires that the various components of the car remote control be compactly installed to meet the requirements of the small volume of the car remote control.

[0004] Since car remote controls are usually small in size and light in weight, on the one hand, existing car remote controls lack a sense of overall weight and do not feel good when used by users; on the other hand, car remote controls contain batteries, especially polymer batteries, so during the charging process of the batteries, high temperatures will cause expansion, which will cause the battery body to become larger over a long period of time, deform the assembly shell, increase the gap, and affect the appearance and performance of the car remote control.

[0005] Therefore, the industry is necessary to provide an improved car remote controller to overcome the prior art defects. Utility Model Content

[0032] In the utility model, a light source is arranged at a position corresponding to the keypad on the PCB board; a corresponding light-transmitting window is provided on the upper cover; a light-guiding block corresponding to the position of the light source is arranged on the PCB board, which guides the light emitted by the light source to pass through the light-transmitting window and transmit to the keypad after multiple convergence and reflection, thereby illuminating the logo in the corresponding area on the keypad, and the brightness is higher than that of the prior art, and the brightness is relatively uniform, so that the user can see the logo clearly even in dim light, thereby improving the overall aesthetics of the car remote control.

[0033] In one embodiment of the present invention, reference Figure 1-5b , a car remote controller 100 is provided, comprising a bottom shell 10, an upper cover 20 fastened and fixed to the bottom shell 10, a PCB board 40 arranged in a closed space formed by the bottom shell 10 and the upper cover 20, and a key board 30 arranged on the upper cover 20.

[0034] The bottom shell 10 and the upper cover 20 can be made of appropriate materials, such as plastic materials, to reduce costs. In addition, in order to enhance the aesthetics, the bottom shell 10 and the upper cover 20 can be electroplated to form metal textures and textures, greatly improving the appearance of the product.

[0035] The keypad 30 may be made of, for example, a soft material so that it can be easily pressed to trigger the relevant circuit inside the car remote controller, thereby realizing the remote control function of the car.

[0036] A light source 42 is arranged at a position of the PCB board 40 corresponding to the key board 30; a light-transmitting window 22 is provided at a position of the upper cover 20 corresponding to the key board 30; a light guide block 90 corresponding to the position of the light source 42 is arranged on the PCB board 40, and the light guide block 90 is arranged to guide the light emitted by the light source 42 to be transmitted from the light-transmitting window 22 to the key board 30.

[0037] The light guide block 90 includes a main body 92, the main body 92 has a top wall 923 and a bottom wall 925 that are relatively arranged, and a front wall 921 and a rear wall 9200 that connect the top wall 923 and the bottom wall 925; the front wall 921 is provided with a focusing groove 9212 corresponding to the position of the light source 42, and the focusing groove 9212 is configured to converge the light emitted by the light source 42 into the focusing groove 9212.

[0038] In addition, the bottom surface of the top wall 923 forms an inclined reflective wall 927, and the height of the inclined reflective wall 927 relative to the bottom wall 925 gradually increases toward the direction of the rear wall 9200. Furthermore, a lens 929 corresponding to the light focusing groove 9212 is disposed at a position of the inclined reflective wall 927 close to the front wall 921, and the lens 929 is configured to further transmit the light gathered in the light focusing groove 9212 to the inclined reflective wall 927.

[0039] In the present invention, the light guide block 90 can effectively guide light, so that sufficient light can be irradiated onto the keypad 30, which is convenient for identifying information on the keypad 30. Specifically, the light focusing groove 9212 is arranged facing the light source 42, and the light emitted by the light source 42 is irradiated into the light focusing groove 9212. Here, the light focusing groove 9212 is a groove structure with a certain height, so the groove surface can reflect and converge the light, and the reflected light passes through the transparent light guide block 90 and irradiates the main body 92, and then passes through the lens 929. The lens 929 further converges the light and projects it onto the inclined reflective wall 927. The reflective wall 927 further reflects the light projected onto itself to the light-transmitting window 22, and finally projects it onto the keypad 30.

[0040] In the above structure, since the light passes through the double focusing effect of the focusing groove 9212 and the lens 929, when it is irradiated to the key panel 30, its brightness is sufficient and can completely illuminate the entire key panel 30. Moreover, after the light after the double focusing effect is reflected by the larger reflective wall 927, the brightness is evenly dispersed, so there will be no uneven light and dark phenomenon on the key panel 30, thereby greatly improving the user experience and aesthetics of the product.

[0041] In the present invention, the light guide block 90 is fixed to the PCB board 40 by an appropriate method. For example, in one embodiment, a bayonet 44 is provided on the PCB board 40; a hook 9252 is formed on the bottom wall 925 of the light guide block 90 near the front wall 921. By inserting the hook 9252 into the bayonet 44, the light guide block 90 is detachably fixed to the PCB board 40. In other embodiments of the present invention, the light guide block 90 can also be fixed to the PCB board 40 by, for example, a threaded connection method. The present invention does not limit this.

[0042] Furthermore, in order to accurately locate the light guide block 90 at a predetermined position on the PCB board 40, a positioning hole 46 may be provided on the PCB board 40; and then a positioning column 9254 may be formed on the bottom wall 925 of the light guide block 90. ​​By tightly inserting the positioning column 9254 into the positioning hole 46, the light guide block 90 can be accurately located and quickly installed relative to the PCB board 40. The specific cross-sectional shapes of the positioning hole 46 and the corresponding positioning column 9254 can be flexibly set, preferably set to a circular cross-section, that is, a circular positioning hole and a cylindrical positioning column, so as to facilitate the plugging of the two.

[0043] In a more preferred embodiment, in order to achieve a fool-proof effect when installing the light guide block 90, positioning holes and positioning columns with, for example, elliptical or other specific cross-sectional shapes can be used. The light guide block 90 can be installed on the PCB board 40 only at the correct angle. At other angles, the light guide block 90 cannot be assembled to the PCB board 40, thereby preventing installation errors, resulting in rework and wasted time.

[0044] In one embodiment, an inner shell 70 is arranged between the bottom shell 10 and the upper cover 20, and the PCB board 40 is arranged at one end of the inner shell 70. A counterweight frame 60 is arranged at the other end of the inner shell 70, and a battery 50 powered by the PCB board 40 is arranged in the counterweight frame 60. For example, a counterweight frame 60 made of zinc alloy can be used to increase its own weight and strength. The counterweight frame 60 can bring obvious technical effects. Specifically, under normal circumstances, the battery is a polymer battery, so during the process of charging the battery, high temperature will cause expansion, which will cause the body size of the battery to increase over a long period of time, causing the assembly shell to deform, the gap to increase, and affect the appearance and performance of the car remote control. In the utility model, by installing the battery 50 in the counterweight frame 60, the metal counterweight frame 60 can assist in heat dissipation of the polymer battery, which reduces the risk of battery bulging on the one hand, and increases the weight of the car remote control on the other hand, so that the user has a sense of weight when using it.

[0045] In one embodiment, the counterweight frame 60 has a bottom plate 62 and a side plate 64 extending from the edge of the bottom plate 62. The bottom plate 62 and the side plate 64 together form a space, and the battery 50 is arranged in the space. The side plate 64 can, on the one hand, limit the battery 50, so as to prevent the battery 50 from shaking inside the remote control when the entire remote control is in use, thereby causing the electrical connection to become loose, thereby affecting normal use. On the other hand, the side plate 64 can further increase the heat dissipation effect on the battery 50. This is because, during the use of the remote control, the battery 50 supplies power to the components inside the remote control, thereby generating heat. By contacting the battery 50 with the bottom plate 62 and the side plate 64, which are made of, for example, metal, heat conduction can be generated, which is beneficial to the heat dissipation of the battery 50 and prevents the battery 50 from being damaged by overheating.

[0046] Preferably, a notch 66 is formed on the side plate 64, and a longitudinally conducting fixing hole 68 is provided on the side plate 64 at the position of the notch 66. When the counterweight frame 60 is mounted on the inner shell 70, the counterweight frame 60 can be fixed by screws passing through the fixing holes 68.

[0047] Preferably, in order to facilitate wireless charging of the battery 50 in the car remote controller 100, a charging coil 80 for wirelessly charging the battery 50 is provided between the bottom shell 10 and the inner shell 70. In this way, the battery 50 can be conveniently charged through a corresponding wireless charger.

[0048] Specifically, the charging coil 80 is attached to the bottom of the inner shell 70 by means of, for example, an adhesive sheet 202. In other embodiments, the charging coil 80 can also be fixed to the bottom of the inner shell 70 by, for example, a snap-fit ​​method or a threaded method. In another embodiment, the charging coil 80 can also be directly fixed in the bottom shell 10.

[0049] Preferably, the keypad 30 has a pressing area 32, and the upper cover 20 is provided with an elastic support sheet 24 corresponding to the pressing area 32, for supporting the entire pressing area 32. Since the elastic support sheet 24 is provided, when the pressing area 32 is pressed down, the elastic support sheet 24 can slowly push the pressing area 32 to its original position and shape under the elastic action, that is, restore the original state, thereby avoiding the situation where the pressing area 32 cannot be bounced up due to long-term operation, and finally ensuring the normal use of the car remote control.

[0050] In one embodiment, a fastening hook 34 is provided on the edge of the key panel 30; correspondingly, a fastening groove 26 is provided on the upper cover 20; the fastening hook 34 is inserted into the corresponding fastening groove 26, so that the key panel 30 can be fastened to the appropriate position of the upper cover 20 conveniently and quickly.

[0051] According to an embodiment of the present invention, an insulating sleeve 204 is disposed between the PCB board 40 and the upper cover 20. The insulating sleeve 204 can insulate the PCB board 40 from other components, thereby preventing a short circuit from occurring.

[0052] Preferably, in one embodiment, a barb 12 is provided on the edge of the bottom shell 10, and correspondingly, a buckle hole 72 is provided on the edge of the inner shell 70; when the inner shell 70 is placed in the bottom shell 10, the barb 12 is inserted into the buckle hole 72, thereby fixing the inner shell 70 in the bottom shell 10.

[0053] In the present invention, the bottom shell 10 and the upper cover 20 can be fixed to each other in various ways, such as by clamping, gluing or threading. In one embodiment of the present invention, the two can be connected and fixed by clamping, such as forming a clamping ring on one of them and setting a corresponding clamping tongue on the other. The bottom shell 10 and the upper cover 20 can be quickly and conveniently clamped to each other by the cooperation of the two. In another embodiment of the present invention, the bottom shell 10 and the upper cover 20 can also be fixed to each other by threading.

[0054] In summary, first of all, in the utility model, the entire car remote control has an ultra-thin shape from front to back, which is very beautiful and attractive. The keypad adopts a PET film sheet key structure to meet the high-gloss black effect of the appearance and realize the key button function and LOGO light-transmitting function. In addition, it is equipped with a wireless charging function, and the zinc alloy counterweight frame assists the polymer battery in heat dissipation and meets the key weight requirement. The light guide block is used to achieve a uniform and bright LOGO light effect in a narrow area.

[0055] Secondly, the car remote control is equipped with a LOGO lighting function, which adopts side lighting, adds a light guide block, and designs a convex mirror structure facing the light source, so that the brightness of the luminous surface can reach an average of, for example, 126nit, and the overall transition is uniform.

[0056] In addition, the buttons of the car remote control are made of a separate PET film process. Through the IML mold hot pressing process, the PET film is tightly fitted with the PA12 thin sheet button shell. The button appearance achieves a high-gloss black effect and meets the LOGO light transmittance performance. The entire button panel is then buckled into the upper cover, and the assembly structure is simple.
