[0001] This utility model relates to the field of automotive parts technology, specifically to a car remote control. Background Technology

[0002] A car remote control is a device used to control the locking and unlocking functions of a car, typically communicating with the vehicle wirelessly. Modern car remote controls are not only used to unlock doors, but also to start the engine, control windows and sunroof, and other functions. They are an important part of the vehicle's safety system, enhancing both convenience and safety for the owner.

[0003] In existing technologies, the design of car remote controls typically involves the assembly of multiple parts, which have certain tolerance variations during manufacturing. During long-term and frequent use, especially during the insertion and removal of the mechanical key and remote control, friction can create significant clearances between the mechanical key and the key handle. These clearances not only affect the overall stability of the remote control but may also lead to the following problems: When carrying the remote control, looseness between the mechanical key and remote control components can cause noise, affecting the user experience. In particular, due to the accumulated tolerances of various parts, there is a large gap in the insertion and removal of the mechanical key and remote control, which leads to looseness during use and further exacerbates the noise problem.

[0004] In addition, traditional designs usually require a large gap between the key handle and the remote control body to ensure smooth insertion and removal. However, this design results in a less tight fit, which affects the overall sturdiness of the remote control, especially during frequent insertion and removal.

[0005] Therefore, there is an urgent need for an improved car remote control to address the aforementioned shortcomings in the existing technology. Utility Model Content

[0006] The purpose of this invention is to solve the above-mentioned problems and provide a car remote control.

[0011] Preferably, the button assembly includes a release button with a latch; a sliding groove is formed on the bottom shell; a slot is formed on the end face of the key handle near the sliding groove; the release button is elastically disposed in the sliding groove, and the latch engages in the slot to prevent the key assembly from disengaging from the bottom shell; the latch is configured to disengage from the slot when pressed, thereby releasing the lock on the key assembly.

[0012] More preferably, the release button has a cavity, and the latch is formed on the inner wall of the cavity; the key handle has a cantilever, and the cantilever has a slot; the cantilever extends into the cavity, and the latch extends into the slot.

[0013] Furthermore, a notch is formed on the groove; the cantilever passes through the notch and extends into the cavity.

[0015] Optionally, the bottom shell has a bottom wall with waterproof and breathable holes.

[0016] Preferably, the mechanical key and the key handle are fixedly connected by rivets.

[0017] Compared with the prior art, the beneficial technical effects of this utility model are as follows: In this invention, a tighter fit is achieved through the design of the tapered positioning post and positioning hole, reducing gaps caused by frictional contact and thus avoiding noise generation.

[0029] refer to Figure 1-7 According to one embodiment, a car remote control 100 includes a base housing 10 and a key assembly 20 that is pluggably mounted on the base housing 10. The key assembly 20 consists of a mechanical key 22 and a key handle 24 mounted on one end of the mechanical key 22. The base housing 10 has a positioning hole 142, and the key handle 24 has a matching positioning post 242. When the positioning post 242 is inserted into the positioning hole 142, a stable fit between the key assembly 20 and the base housing 10 can be achieved.

[0030] In the above embodiment, by designing positioning holes on the bottom shell of the car remote control and setting corresponding positioning pins on the key handle, a tighter connection can be achieved between the key assembly and the bottom shell. Specifically, the positioning pins are precisely inserted into the positioning holes, thereby ensuring a firm fit between the key assembly and the bottom shell. This design effectively solves the common problem of gaps in the fit of traditional car remote controls during use, especially reducing noise and loosening caused by excessive gaps.

[0031] It is important to note that the bottom shell 10 is typically made of high-strength plastic or aluminum alloy. Plastic bottom shells are often manufactured using injection molding. This process ensures the complexity of the bottom shell's shape and dimensional accuracy, and the plastic material is lightweight and durable, suitable for long-term use. Aluminum alloy bottom shells are manufactured using aluminum alloy die casting or extrusion molding processes, possessing strong corrosion resistance and impact resistance, effectively protecting internal electronic components.

[0032] In one embodiment, the mechanical key 22 is typically made of cupronickel or alloy material, produced through stamping or forging processes to ensure sufficient hardness and durability. The key teeth at its end are customized to the requirements of the door lock to ensure smooth insertion. The key handle 24 is usually made using a die-casting process, from zinc alloy or other materials, providing a comfortable feel while ensuring grip and wear resistance during operation. The key handle may also incorporate anti-slip textures to enhance stability during use.

[0033] According to one embodiment, the positioning hole 142 typically employs a tapered design. This not only helps the positioning post 242 to be inserted more precisely, but also ensures a better fit during insertion due to the self-aligning properties of the tapered shape. The positioning post 242 is also tapered in shape to match this design, with rounded tips to reduce friction and ensure smoother insertion and removal operations. The injection molding process allows these two components to be produced efficiently and precisely to meet design requirements in terms of size and shape, thereby ensuring a tight fit and preventing noise or instability caused by loosening.

[0034] Throughout the assembly process of the car remote control 100, the positioning pin 242 is inserted into the positioning hole 142 to achieve a secure fit between the key assembly 20 and the base shell 10. Thanks to precision injection molding technology, the fit between the positioning pin and the positioning hole is extremely tight, ensuring that the key assembly will not loosen or produce abnormal noises during daily use. Especially during frequent insertion and removal, this design reduces gaps caused by component tolerances, improving the stability of the remote control and the user experience.

[0035] According to one embodiment, both the positioning hole 142 and the positioning post 242 adopt a tapered design. The end of the positioning hole 142 has a first annular positioning tapered surface 1422, while the end of the positioning post 242 forms a second annular positioning tapered surface 2422. The engagement between these two annular tapered surfaces guides the positioning post 242 smoothly into the positioning hole 142. The tapered design not only provides a more precise fit but also enables self-alignment during insertion, reducing the need for human intervention. Traditional linear insertion structures often suffer from poor insertion or loose fit due to tolerance issues, affecting the user experience of the remote control. The tapered design ensures precise alignment between the positioning post and the positioning hole, enhancing the overall structural robustness and long-term stability. Furthermore, this design reduces friction during insertion and removal, lowering wear and noise caused by friction.

[0036] Furthermore, in this invention, the car remote control 100 may further include a button assembly 30 for maintaining or releasing the fixed relationship between the button assembly 20 and the bottom shell 10.

[0037] Specifically, the button assembly 30 may have a release button 32, on which a latch 322 is provided; a sliding groove 144 is provided on the bottom shell 10; a slot 244 is provided on the end face of the key handle 24 near the sliding groove 144; the release button 32 is elastically disposed in the sliding groove 144, and the latch 322 is engaged in the slot 244, thereby preventing the key assembly 20 from disengaging from the bottom shell 10; the latch 322 is configured to disengage from the slot 244 when pressed, thereby releasing the lock on the key assembly 20.

[0038] Here, the button assembly 30 secures the key assembly to the base housing through the cooperative design of the latch 322 and the slot 244. When not pressed, the latch 322 firmly engages with the slot 244, preventing the key assembly from detaching from the base housing. Only when the release button 32 is pressed will the latch 322 disengage from the slot 244, releasing the connection. This structure allows the key assembly to be securely fixed within the base housing during use, and when disassembly is required, it can be easily unlocked by simply pressing the button.

[0039] This design simplifies disassembly and improves user convenience. Simultaneously, the tight fit between the latch and the slot reduces accidental operation caused by external forces, ensuring the key assembly won't accidentally detach during normal use, thus enhancing security. Compared to traditional mechanical connections, the latch structure not only improves operational flexibility but also prevents noise or instability caused by loosening.

[0040] Furthermore, a cavity 324 can be formed on the release button 32, and correspondingly, a latch 322 is formed on the inner wall of the cavity 324; a cantilever 246 is formed on the key handle 22, and a slot 244 is formed on the cantilever 246; the cantilever 246 extends into the cavity 324, and the latch 322 extends into the slot 244. In addition, a notch 146 is formed on the slide groove 144; the cantilever 246 passes through the notch 146 and extends into the cavity 324. A compression spring 34 is provided between the release button 32 and the slide groove 144.

[0041] In this invention, the activation button 32 is connected to the key handle 24 via a snap-fit, ensuring a secure connection between the key handle and the base shell. The button snap-fit ​​structure features a reinforced design, capable of withstanding far greater tensile forces than usual, ensuring no damage even under extreme conditions. For example, the snap-fit ​​design effectively prevents loosening due to prolonged use or external forces, ensuring the key assembly remains firmly fixed in the remote control. This design not only improves the stability of button operation but also reduces malfunctions caused by button loosening or detachment, enhancing the remote control's safety and durability. Furthermore, the increased snap-fit ​​strength allows the button to continue functioning normally under high tensile force or accidental impact, further improving the remote control's reliability.

[0042] According to one embodiment, the release button 32 is installed via the cooperation of a slide groove 144 and a cantilever 246. The cantilever 246 extends into the cavity 324 of the release button and engages with the slot 244 via a latch 322, ensuring the key assembly is secured. The notch 146 on the slide groove 144 allows the cantilever 246 to pass smoothly through for installation. This design ensures the stability of the button assembly and, through the cooperation of the slide groove and the cantilever, reduces problems such as jamming or improper engagement caused by long-term use. The combination of the slide groove and the cantilever makes the button operation smoother, reducing malfunctions caused by improper engagement or inaccurate slot matching, thereby improving the overall user experience.

[0043] In addition, the bottom wall 12 of the bottom shell 10 is designed with waterproof and breathable holes 122, and is equipped with a waterproof and breathable membrane inside. The function of the waterproof and breathable membrane is to prevent moisture from entering the remote control, while also releasing the gas inside the cavity to avoid pressure buildup in high temperature or humidity environments.

[0044] Specifically, the waterproof and breathable membrane design protects the remote control's internal electronic components from moisture while preventing damage from external high temperatures or humidity. In high-temperature environments, the pressure generated by air expansion can cause the remote control to deform or damage its internal circuitry. The waterproof and breathable membrane effectively solves this problem, enhancing the remote control's durability and extending its lifespan.

[0045] In addition, this design avoids the appearance expansion or abnormal noise that may occur in traditional products due to temperature and humidity changes, thus improving the reliability of the product.

[0046] In another preferred embodiment, the mechanical key 22 and the key handle 24 are connected by rivets 26, so that the two form an integral structure, which greatly improves the ease of use and flexibility.

[0047] In summary, in the various embodiments of the car remote control provided by this utility model, a positioning hole is provided on the bottom shell of the car remote control, and a positioning post is provided on the key handle, achieving a tight fit between the key assembly and the bottom shell. Specifically, the positioning post is tightly inserted into the positioning hole, ensuring a firm connection between the key assembly and the bottom shell. This design solves some common problems in the use of traditional car remote controls, especially noise and loosening caused by gaps in the fit.

[0048] First, the positioning holes and posts in the design employ a tapered structure. This structure allows for a tight fit during insertion, reducing clearance caused by friction. In traditional designs, frequent insertion and removal often results in significant gaps between the mechanical key and key handle and the base case, leading to mechanical collision noise during carrying. This design effectively avoids this problem. Precise positioning ensures a more stable connection between the key assembly and the base case, improving both product durability and user experience.

[0049] Secondly, because this design reduces the interaction between multiple parts as in traditional designs, it minimizes the impact of tolerance accumulation on installation, resulting in a more stable fit between the key assembly and the base shell. In traditional technology, due to larger part tolerances, a larger clearance is required to ensure smooth installation and disassembly, which can lead to the key handle becoming loose on the remote control. This solution, however, avoids this loosening problem through precise positioning pins and holes, ensuring the key assembly is firmly fixed to the remote control, thereby improving the overall structural robustness.

[0050] Finally, the overall design enhances the structural stability of the remote control, avoiding gaps caused by friction during long-term use. Compared to the instability caused by loose parts and manufacturing tolerance differences in traditional designs, this solution, through simple structural improvements, ensures a secure installation of the key assembly, reducing noise or loosening issues caused by long-term use, making the car remote control quieter and more robust during operation.

[0051] In summary, this technical solution solves the problems of loose fit and noise in traditional technologies by using precise matching of positioning pins and positioning holes, thereby improving the stability of car remote controls and user experience.

Furthermore, other steps, measures, and solutions in the various operations, methods, and processes discussed in this application can also be alternated, modified, rearranged, decomposed, combined, or deleted. Furthermore, steps, measures, and solutions in the prior art that are similar to those disclosed in this application can also be alternated, modified, rearranged, decomposed, combined, or deleted.

[0053] The above description is only a partial embodiment of this application. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this application, and these improvements and modifications should also be considered within the scope of protection of this application.
