The remote control and transmitter are integrated into the car key. The vehicle can enter the locked or unlocked state according to the signal sent by the smart key, and can even automatically close the windows and sunroof.

[0003] At present, most of the ways to supplement the power of smart car keys on the market are still traditional plug-in charging or directly replacing the internal battery. However, it is troublesome to frequently replace the battery of car keys, and plug-in charging requires a charging cable to be equipped in the car or at home to charge the car key. For this reason, people apply wireless charging technology to the charging method of smart car keys, mainly by using the alternating magnetic field generated between coils to transmit electric energy to charge the smart car keys. However, smart car keys and wireless chargers are generally separated. When the smart car keys have no power, they need to find a wireless charger to charge, which is cumbersome. If the smart car key is placed in the wireless charging area on the dashboard of the car for charging, the wireless charging area cannot fix the smart car key, resulting in the smart car key shaking in the wireless charging area during driving and poor fit, which affects the charging rate or even fails to charge.

[0004] Therefore, it is necessary to improve the structure of the existing car smart key and wireless charger to ensure normal wireless charging between the two while increasing the connection stability between the two to prevent accidental touches from affecting the wireless charging rate or preventing charging.

[0023] In this embodiment, the plug-in structure includes an insertion component 7 and a pushing component 6. The insertion component 7 is slidably arranged inside the key body 1, and the pushing component 6 is used to push the insertion component 7 to extend out of the key body 1 and be plugged into the fixing component 5. Since the insertion component 7 is slidably arranged inside the key body 1, the plug-in structure in this scheme mainly realizes the plug-in action by extending the insertion component 7 out of the key body 1 and inserting it into the fixing component 5 and then connecting and fixing it, and the insertion component 7 is mainly pushed out of the key body 1 by the pushing component 6.

[0024] In this embodiment, the key body 1 is provided with a receiving cavity opened toward the bottom of the key body 1, the receiving cavity is used to install the insertion component 7, and the top of the key body 1 is provided with a mounting groove for installing the push component 6; Figure 2 and Figure 4 As shown, the accommodating cavity is formed by a depression from the bottom of the key body 1 toward the top of the key body 1, and is mainly used to accommodate the insertion component 7 in the key body 1 when it is not charged to prevent the insertion component 7 from being exposed; and the installation groove is formed by a depression from the top of the key body 1 toward the bottom of the key body 1, and is mainly used to install the pushing component 6.

[0025] In this embodiment, the insertion component 7 includes a plug-in block 72 and an insertion magnetic block 73. The plug-in block 72 can be pushed to slide in the accommodating cavity toward the direction close to the fixing component 5 and extend out of the accommodating cavity. The insertion magnetic block 73 is arranged at the bottom of the plug-in block 72 and is used to be connected with the fixing component 5 after being inserted into the fixing component 5. Figure 2As shown, the plug-in block 72 is slidably disposed in the accommodating cavity, and can be pushed out of the accommodating cavity by the pushing component 6 and extend into the interior of the fixing component 5 and connected and fixed with the fixing component 5 by inserting the magnetic block 73 .

[0026] In this embodiment, a return spring 71 is further included for providing a rebound tension to the plug-in block 72 extending out of the accommodating cavity. One end of the return spring 71 is fixed to the bottom of the accommodating cavity, and the other end is fixed to the top of the plug-in block 72. Figure 2 As shown, the return spring 71 is in a normal state, the plug-in block 72 and the inserted magnetic block 73 are both located in the accommodating cavity, and when the plug-in block 72 is pushed out of the accommodating cavity, the return spring 71 is stretched, exerting a rebound tension on the plug-in block 72 .

[0027] In this embodiment, a connecting hole is provided between the installation slot and the accommodating cavity, and the pushing component 6 includes a pushing button 61 slidably provided in the installation slot and a pushing rod 62 provided at the bottom of the pushing button 61 and extending into the accommodating cavity through the connecting hole, and the pushing rod 62 is used to push the plug-in block 72 out of the accommodating cavity and inserted into the fixing component 5; Figure 2 and Figure 4 As shown, the push button 61 and the push rod 62 are connected to form a whole. When the key body 1 is placed on the charging seat 2, the user manually presses the push button 61 downward to drive the push rod 62 to push the plug-in block 72 located below it until the plug-in block 72 is inserted into the fixed seat 51.

[0028] In this embodiment, the fixing assembly 5 includes a fixing seat 51 arranged on the top of the charging seat 2, and a plug-in slot is arranged on the top of the fixing seat 51, and a fixing magnetic block 52 for cooperating with the insertion magnetic block 73 is arranged in the plug-in slot; Figure 2 and Figure 3 As shown, when the plug-in block 72 is pushed into the plug-in slot, the plug-in block 72 can be fixed in the fixing assembly 5 by magnetic attraction between the inserted magnetic block 73 and the fixed magnetic block 52, thereby achieving enhanced connection strength and connection stability between the key body 1 and the charging seat 2.

[0029] In this embodiment, the top of the charging seat 2 is symmetrically provided with positioning grooves 53 for aligning and fitting the charging input piece 3 and the charging output piece 4 on both sides opposite to the charging output piece 4; by providing the positioning grooves 53, it is convenient to align the charging input piece 3 on the key body 1 with the charging output piece 4, thereby ensuring subsequent normal charging.

[0030] In this embodiment, when the key body and the charging seat are installed: the key body 1 only needs to be placed on the charging seat 2 so that the charging input piece 3 and the charging output piece 4 are in contact with each other, and the key body 1 can be charged. Then, by pressing the push button 61 downward, the push rod 62 can be driven to push the plug-in block 72 located below it to move downward until the plug-in block 72 is inserted into the fixed seat 51, so that the fixed magnetic block 52 and the inserted magnetic block 73 can be connected to each other, and the installation can be completed.

[0031] When the key body is removed from the charging base: Since the key body and the charging base are mainly connected by the magnetic force of the inserted magnetic block 73 and the fixed magnetic block 52, the user can manually remove the key body from the charging base with a little force. At this time, the plug-in block 72 returns to the accommodating cavity under the pulling force of the reset spring 73 and pushes the bottom of the push rod 62 to move toward the bottom of the accommodating cavity to the initial state. At this time, the push button 61 also moves upward from the mounting groove to the initial state.

[0032] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
