Description
Technical Field
[0001] This invention belongs to the field of automotive electronics technology. Specifically, this invention relates to a battery cover system for an automotive smart remote control. Background Technology
[0002] As cars become increasingly intelligent, smart remote controls have become a core component for user interaction with vehicles. These remote controls typically use button batteries for power, which need to be replaced when they run out of life. Currently, many smart remote controls on the market use concealed or high-strength clip designs for their battery covers, which often require special tools to open. This causes great inconvenience for ordinary users when replacing batteries in daily use, and improper operation may even lead to scratches on the casing or damage to the clips.
[0003] While existing technologies have attempted to simplify battery cover structures, most have failed to systematically resolve the contradictory relationship between "easy to open" and "securely locked." Either the opening is convenient but the locking is weak, easily coming loose during drops; or the locking is reliable but opening is extremely difficult. Therefore, a systematic solution is urgently needed to achieve a simple and quick opening and closing operation without special tools, while ensuring a reliable locking of the battery cover.
[0004] Patent application CN107829611A, published on March 23, 2018, discloses a car remote control key and a car. The car remote control key includes: a remote control key body; a rechargeable battery fixed inside the remote control key body; a coil fixed inside the remote control key body and electrically connected to the rechargeable battery; a magnet located inside the remote control key body; and a rotation drive mechanism fixedly connected to the magnet and partially extending outside the remote control key body. The rotation drive mechanism drives the magnet to rotate around an axis, changing the magnetic flux within the coil, generating current, and charging the rechargeable battery. However, this car remote control key does not solve the aforementioned technical problem. Summary of the Invention
[0005] The purpose of this invention is to address the shortcomings of existing technologies by providing a battery cover system and battery replacement method for a car smart remote control that enables simple and quick opening and closing operations without the need for special tools, while ensuring reliable locking of the battery cover.
[0006] To achieve the above objectives, the technical solution adopted by the present invention is as follows: The battery cover system of the car smart remote control includes a remote control inner shell and a battery rear cover. The remote control inner shell and the battery rear cover are connected by a locking and releasing coordination mechanism, and one end of the battery rear cover is provided with an unlocking structure.
[0007] The locking and releasing coordination mechanism includes multiple latch groups, which are arranged sequentially along the longitudinal direction of the battery rear cover. The inner shell of the remote control is provided with a latching protrusion corresponding to the latch group. The unlocking structure includes an opening notch located at one end of the battery rear cover.
[0008] The latching assembly includes a first latching assembly, a second latching assembly, and a third latching assembly. The first latching assembly is located at one end of the battery back cover, the second latching assembly is located at the middle of both sides of the battery back cover, and the third latching assembly is located at the other end of the battery back cover.
[0009] Both the second and third latching groups are connected to the inner shell of the remote control by elastic walls.
[0010] The battery back cover has an arc-shaped part at one end, and the first buckle assembly is located on the arc-shaped part.
[0011] The remote control has a battery compartment in the middle of its inner shell, and a battery is located inside the battery compartment; a positioning notch is provided at one end of the battery compartment, and an inner battery cover is provided above the battery.
[0012] One end of the battery inner cover is provided with a positioning block corresponding to the positioning notch, the side of the battery compartment is provided with a limiting step, the upper surface of the battery is coplanar with the limiting step, and the upper surface of the battery inner cover is coplanar with the upper surface of the remote control inner shell.
[0013] The remote control also has a locking block on the side of the inner shell, and multiple bolt holes on the inner shell.
[0014] The battery replacement method for this car smart remote control utilizes the aforementioned battery cover system and includes the following steps: Step 1: Use a tool to apply force at the opening notch to separate the third latch assembly from the inner shell of the remote control; Step 2: Continue to apply force to separate the second latch assembly from the inner shell of the remote control; Step 3: Rotate the battery back cover around the first latch group to separate the first latch group from the inner shell of the remote control; Step 4: Replace the battery; Step 4: Align the first latch group and fasten it onto the inner shell of the remote control. Press down the battery cover to lock the second and third latch groups into the inner shell of the remote control.
[0015] The technical advantages of this invention are as follows: The battery cover system of the automotive intelligent remote control of this invention connects the remote control inner shell and the battery rear cover via a multi-buckle collaborative locking and releasing mechanism. This mechanism includes at least three sets of buckle groups distributed longitudinally along the battery rear cover. Each set of buckle groups has a different self-locking angle and functional positioning. The head buckle group provides the main locking force, the middle buckle group prevents the battery rear cover from arching, and the tail buckle group forms an easily triggered unlocking starting point. The buckle groups located in the middle and tail sections of the battery rear cover are integrated with elastic wall structures, allowing them to undergo elastic deformation when subjected to assembly stress and unlocking external force.
[0016] Based on this battery cover system, the present invention also provides a corresponding battery replacement method. Users only need to apply a push force at the tail notch using a general tool to release the latches in sequence, realizing the opening and closing of the battery cover quickly and without damage without special tools, which significantly improves the user experience and product reliability.
[0017] In summary, the present invention has the following technical effects: 1. Systematic buckle design: Multiple buckles are integrated into a whole system to lock with the inner shell of the remote control, and the locking function of each buckle is designed differently, which solves the contradiction between "easy to open" and "secure locking" in existing car remote controls.
[0018] 2. Excellent user experience: Users can easily replace batteries with common items such as a flathead screwdriver without relying on special tools, greatly improving convenience.
[0019] 3. High reliability: The differentiated buckle design ensures that the battery back cover will not come loose during normal use and accidental drops, while the elastic wall structure ensures that the buckle can maintain good performance and appearance after multiple disassemblies, extending the product life.
[0020] 4. Standardized battery replacement method: The battery replacement method is clear and easy to master, reducing the user's operating threshold and the risk of damage caused by improper operation. Attached Figure Description

[0023] The specific embodiments of the present invention will be further described in detail below with reference to the accompanying drawings, in order to help those skilled in the art to have a more complete, accurate and in-depth understanding of the inventive concept and technical solution of the present invention, and to facilitate its implementation.
[0024] like Figure 1 and Figure 2 As shown, the battery cover system of this car smart remote control includes a remote control inner shell 1 and a battery rear cover 2. The remote control inner shell 1 and the battery rear cover 2 are connected by a locking and releasing mechanism, and one end of the battery rear cover 2 has an unlocking structure. The battery rear cover 2 and the remote control inner shell 1 are detachably connected by the locking and releasing mechanism, achieving a balance between convenient opening and secure locking. Both are integrally molded from wear-resistant and elastic engineering plastics through injection molding. The battery rear cover 2 can be installed onto the remote control body without any tools, making it easy for users to operate themselves. During operation, simply pre-install the battery rear cover 2 on the snap-fit protrusion 6 at the head of the remote control inner shell 1, then rotate it downwards and press it into the middle and tail clips of the battery rear cover 2 to snap into the remote control inner shell 1. Conversely, to remove the battery rear cover 2, simply use a common flathead screwdriver or similar tool to gently pry open the battery rear cover 2 from the opening notch 9 at the tail, causing the tail to pop open.
[0025] like Figure 1 and Figure 2 As shown, the locking and releasing coordination mechanism includes multiple latch groups, which are arranged sequentially along the longitudinal direction of the battery back cover 2. The inner shell 1 of the remote control has a latching protrusion 6 corresponding to the latch groups. The unlocking structure includes an opening notch 9, which is located at one end of the battery back cover 2. Each latch group has a different self-locking angle, allowing it to play different roles when locking: the latch group located at the head of the battery back cover 2 ensures the main locking force, the latch group located in the middle of the battery back cover 2 prevents the middle of the battery back cover 2 from arching, and the latch group located at the tail of the battery back cover 2 is easier to unlock first due to its smaller self-locking angle. The opening notch 9 serves as a common tool or item for prying open the battery back cover 2 for easy removal when the user needs to replace the battery 17.
[0026] like Figure 1 As shown, the latching assembly includes a first latching assembly 3, a second latching assembly 4, and a third latching assembly 5. The first latching assembly 3 is located at one end of the battery back cover 2, the second latching assembly 4 is located at the middle of both sides of the battery back cover 2, and the third latching assembly 5 is located at the other end of the battery back cover 2. The first latching assembly 3, the second latching assembly 4, and the third latching assembly 5 are respectively located at the head, middle, and tail of the battery back cover 2. The three have different inclined locking angles to achieve differentiated locking functions. The first latching assembly 3 is designed with a larger locking angle than the second and third latching assemblies 5 to provide the main locking force. The second latching assembly 4 is used to constrain the displacement of the middle of the battery back cover 2 relative to the inner shell 1 of the remote control. The third latching assembly 5 is designed with the smallest locking angle, serving as the initial trigger point for the unlocking operation.
[0027] like Figure 1 As shown, both the second latch group 4 and the third latch group 5 are connected to the inner shell 1 of the remote control by elastic walls 8. The elastic walls 8 extend from the inner wall of the battery back cover 2 and have a certain height and thickness. The latching ends of the second latch group 4 and the third latch group 5 are set on the corresponding elastic walls 8, so that the second and third latch groups 5 can undergo elastic displacement when subjected to external force, which optimizes the opening feel of the battery back cover 2 and avoids damage. During the unlocking process of the battery back cover 2, the elastic deformation of the elastic walls 8 absorbs energy, protects the latches themselves, and makes the opening action smoother.
[0028] like Figure 1 As shown, one end of the battery back cover 2 has an arc-shaped portion 7, and the first latch group 3 is located on the arc-shaped portion 7. The arc-shaped portion 7 is adapted to the shape of the battery inner cover 11, which changes the orientation of the latching end of the first latch group 3, so that the connection between the first latch group 3 and the remote control inner shell 1 forms a temporary hinge point when the battery back cover 2 is removed and a pre-installation point when the battery back cover 2 is installed. When removing the battery back cover 2, the first latch group 3 serves as a temporary hinge point, so that when the third latch group 5 and the second latch group 4 are released in sequence, the first latch group 3 of the battery back cover 2 can be pre-installed on the remote control inner shell 1, which facilitates the sequential latching of the second latch group 4 and the third latch group 5.
[0029] like Figure 2 As shown, a battery compartment 10 is provided in the middle of the inner shell 1 of the remote control, and a battery 17 is provided inside the battery compartment 10; a positioning notch 12 is provided at one end of the battery compartment 10, and a battery inner cover 11 is provided above the battery 17. The battery compartment 10 is formed by slotting in the inner shell 1 of the remote control, and the battery inner cover 11 is installed above the battery 17 to protect it and further prevent the battery 17 from falling out.
[0030] like Figure 5As shown, one end of the battery inner cover 11 is provided with a positioning block 13 corresponding to the positioning notch 12, and the side of the battery compartment 10 is provided with a limiting step 14. The upper surface of the battery 17 is coplanar with the limiting step 14, and the upper surface of the battery inner cover 11 is coplanar with the upper surface of the remote control inner shell 1. The correspondence between the positioning block 13 and the positioning notch 12 helps to avoid incorrect installation of the battery inner cover 11. The size of the positioning block 13 is smaller than the positioning notch 12, and a gap is reserved between the two to facilitate the user to remove the battery inner cover 11. When the battery 17 is installed at the bottom of the battery compartment 10, the bottom end of the battery inner cover 11 is stably in contact with the limiting step 14, and the upper surface of the battery inner cover 11 will be on the same smooth plane as the upper surface of the remote control inner shell 1. The above structure can be used as a reference for the user to judge whether the battery 17 is installed correctly. If the user does not install the battery 17 correctly, the battery inner cover 11 will protrude from the remote control inner shell 1, and the user can easily judge and adjust the battery 17.
[0031] like Figure 2 As shown, the inner shell 1 of the remote control also has a locking block 15 on its side; the inner shell 1 of the remote control also has multiple bolt holes 16. A locking block 15 is provided on both sides of the locking protrusion 6 in the middle of the inner shell 1 of the remote control. The locking block 15 can lock the inner shell 1 of the remote control onto the remote control body. The inner shell 1 of the remote control also has multiple groove structures on its side. The locking blocks 15 and the locking protrusion 6 in the middle of the inner shell 1 of the remote control are all located on the corresponding groove structures, which guide and limit the vertical installation of the inner shell 1 of the remote control, facilitating further tightening of the bolts. There are three bolt holes 16, two of which are located on the side near the first latch group 3 and are symmetrically arranged, and the other is located between the two latches of the third latch group 5, so that the bolts provide a uniform tightening effect on the connection of the inner shell 1 of the remote control.
[0032] The battery replacement method for this car smart remote control utilizes the aforementioned battery cover system, such as... Figures 3-6 As shown, it includes the following steps: Step 1: Use a tool to apply force at the opening notch 9 to separate the third latch group 5 from the inner shell 1 of the remote control; Step 2: Continue to apply force to separate the second latch assembly 4 from the inner shell 1 of the remote control; Step 3: Rotate the battery back cover 2 around the first latch group 3 to separate the first latch group 3 from the remote control inner shell 1; Step 4: Replace battery 17; Step 4: Align and fasten the first latch group 3 onto the inner shell 1 of the remote control, and press the battery back cover 2 to lock the second and third latch groups 5 into the inner shell 1 of the remote control.
[0033] The battery replacement method for this car smart remote defines a standard operating procedure: insert a universal tool from the rear notch, use leverage to release the rear and middle clips in sequence, and finally allow the head clip to open naturally. When closing, follow the order of "head first, then press," and confirm proper installation through auditory and tactile feedback.
[0034] The specific procedure for battery replacement is as follows: 1. Unlocking steps: Use a general tool to apply a pushing force to the preset notch at the tail of the battery back cover 2. This pushing force first overcomes the self-locking force of the third buckle group 5, causing it to separate from the snap-fit protrusion 6 of the remote control inner shell 1. 2. Sequential release steps: As the third latch group 5 at the tail is released, the applied thrust or the resulting lever action continues to be transmitted, causing the second latch group 4 with the associated elastic support structure to undergo elastic deformation in sequence and separate from the latching boss 6. 3. Opening steps: After the third and second latch groups 4 are released, the battery back cover 2 rotates around the temporary fulcrum formed by the first latch group 3, so that the first latch group 3 is finally separated, thereby realizing the complete opening of the battery back cover 2; Battery replacement steps: After the battery back cover 2 is opened, the battery compartment 10 is exposed, and the battery inner cover 11 is removed to take out and replace the battery 17. 4. Closing steps: First, align and fasten the first latch group 3 at the head of the battery back cover 2 with the corresponding latching protrusion 6 on the inner shell 1 of the remote control. Then, press down on the battery back cover 2 so that the second and third latch groups 5, with the assistance of the elastic wall 8, pass over the latching protrusion 6 and make a "click" sound to lock in place, thus completing the assembly.
[0035] Example: Both the battery back cover 2 and the remote control inner shell 1 are injection molded from high-performance engineering plastics such as PC or PC / ABS. The inner side of the battery back cover 2 has six symmetrically arranged latches. The two latches at the head of the battery back cover 2 form the first latch group 3, with a self-locking angle of 5° to ensure a strong lock. The two latches in the middle of the battery back cover 2 form the second latch group 4, with a self-locking angle of 10°, and are located on the elastic wall 8; their main function is to prevent the battery back cover 2 from arching. The two latches at the tail of the battery back cover 2 form the third latch group 5, with a self-locking angle of 15°, also located on the elastic wall 8, serving as an easily triggered unlocking point.
[0036] 1. When assembling the battery back cover 2, first align the first snap group 3 at the head of the battery back cover 2 with and snap it into the corresponding snap protrusion 6 on the inner shell 1 of the remote control. Then press down on the battery back cover 2. The inclined surfaces of the second snap group 4 and the third snap group 5 will press the elastic wall 8 and deform it until it passes the protrusion of the inner shell 1 of the remote control and springs back to lock, accompanied by a clear "click" sound.
[0037] 2. When removing the battery back cover 2, if Figure 4As shown, the user inserts a flathead screwdriver into the notch at the tail and pries upwards. The force first acts on the third latch group 5, which is easy to disengage due to its small self-locking angle. After disengagement, the leverage force generated by prying will continue to force the elastic wall 8 of the second latch group 4 to deform, causing it to slide off the locking protrusion 6. Once the constraints at the tail and middle are released, the first latch group 3 at the head can be easily disengaged, and the battery back cover 2 can be fully opened.
[0038] The battery cover system of this car smart remote control connects the remote control inner shell 1 and the battery rear cover 2 via a multi-buckle coordinated locking and releasing mechanism. This mechanism includes at least three sets of buckle groups distributed longitudinally along the battery 17 and battery rear cover 2. Each set of buckle groups has a different self-locking angle and functional positioning. The head buckle group provides the main locking force, the middle buckle group prevents the battery rear cover 2 from arching, and the tail buckle group forms an easily triggered unlocking starting point. The buckle groups located in the middle and tail of the battery rear cover 2 are integrated with an elastic wall structure 8, allowing them to undergo elastic deformation when subjected to assembly stress and unlocking external force.
[0039] Based on this battery cover system, the present invention also provides a corresponding battery replacement method. Users only need to apply a push force at the tail notch using a general tool to release the latches in sequence, realizing the opening and closing of the battery cover quickly and without damage without special tools, which significantly improves the user experience and product reliability.
[0040] In summary, the battery cover system and battery replacement method of this car smart remote control have the following technical advantages: 1. Systematic snap-fit design: Multiple snap-fits are integrated into a single system to lock firmly into the inner shell 1 of the remote control. The locking function of each snap-fit is differentiated, resolving the contradiction between "easy to open" and "securely locked" in existing car remote controls. 2. Excellent user experience: Users can easily replace the battery using common items such as a flathead screwdriver without relying on special tools, greatly improving convenience. 3. High reliability: The differentiated snap-fit design ensures that the battery cover 2 will not loosen during normal use or accidental drops. The elastic wall structure 8 ensures that the snap-fits maintain good performance and appearance after multiple disassemblies, extending product lifespan. 4. Standardized battery replacement method: The battery replacement method is clear and easy to master, reducing the user's operational threshold and the risk of damage due to improper operation.
[0041] The present invention has been described above by way of example with reference to the accompanying drawings. Obviously, the specific implementation of the present invention is not limited to the above-described manner. Any non-substantial improvements made using the inventive concept and technical solution; or the direct application of the inventive concept and technical solution to other situations without modification, are all within the protection scope of the present invention.
