[0033] like Figure 1As shown, a device 100 with a detachable antenna structure is provided in an embodiment of the present invention. The device 100 can be applied to any scenario related to the antenna structure 1. For example, an automobile diagnostic system, the automobile diagnostic system generally includes a vehicle, an automobile diagnostic device, and an automobile communication interface device, the automobile communication interface device is connected to the vehicle, and the automobile communication interface device is wirelessly connected to the automobile diagnostic device, and the automobile communication interface device is used to transmit instructions and data between the automobile diagnostic device and the vehicle, so as to manage and diagnose the vehicle. In the following embodiments, the device 100 with a detachable antenna structure is used as an example of the automobile communication interface device.

[0034] like Figure 1 and Figure 2 As shown, the device 100 with a detachable antenna structure includes an antenna structure 1, a flexible sleeve 2 and a shell 3 with an inner cavity 31. Specifically, the peripheral wall of the shell 3 is arranged on the side wall of the shell 3, and the inner cavity 31 of the shell 3 is formed between the peripheral wall of the shell 3 and the side wall of the shell 3. A mounting portion 4 may be provided on the outer peripheral wall of the shell 3, and the mounting portion 4 may have a mounting groove 41 connected to the inner cavity 31 of the shell 3, that is, the notch of the mounting groove 41 is arranged on the peripheral wall of the shell 3. The shell 3 and the mounting portion 4 may be an integrally formed structure. Of course, in other embodiments, the mounting portion 4 and the shell 3 may also be a detachable structure, which may be realized by plug-in fitting or screw fitting. The flexible sleeve 2 may be sleeved on the antenna structure 1, and the flexible sleeve 2 may be inserted in the mounting groove 41, that is, the antenna structure 1 realizes the fixed installation of the antenna structure 1 and the shell 3 through the plug-in fitting of the flexible sleeve 2 and the mounting groove 41. The flexible cover 2 has a certain degree of softness, and the antenna structure 1 is in soft contact with the mounting groove 41 through the flexible cover 2, so that when the device 100 vibrates, falls or bumps, the flexible cover 2 can buffer the antenna structure 1, effectively avoiding the risk of the antenna structure 1 breaking due to impact, and ensuring that the function of the antenna structure 1 is not affected so that it can continue to be used normally.

[0035] In summary, compared with the prior art, the device 100 with a detachable antenna structure has at least the following beneficial effects:

[0036] The flexible sleeve 2 of the device 100 is in elastic contact with the antenna structure 1 and the mounting groove 41, that is, the face shell 3 and the antenna structure 1 are designed with double elastic buffering and energy absorption, so that the flexible sleeve 2 can play a buffering role when the device 100 falls, and effectively avoids the risk of the antenna structure 1 being broken due to impact; and, the antenna structure 1 is fixedly installed by replacing glue through the snap-fitting cooperation between the flexible sleeve 2 and the mounting groove 41, which effectively avoids the risk of contamination of the antenna structure 1 by the gluing process, so as to ensure that the function and efficiency of the antenna structure 1 are not affected, and the high reliability of the device 100 is ensured, and the product yield and life are guaranteed; in addition, the antenna structure 1 is fixedly installed with the face shell 3 through the plug-in cooperation between the flexible sleeve 2 and the mounting groove 41, without relying on other equipment, and has high production efficiency.

[0037] In some embodiments, Figure 2 and Figure 3 As shown, the flexible sleeve 2 includes a sleeve 21 sleeved on the antenna structure 1. The sleeve 21 may be a structure with an open end. The open end of the sleeve 21 and the slot of the mounting slot 41 may be in the same direction. When the antenna structure 1 is completely accommodated in the sleeve 21, the open end of the sleeve 21 is flush with the end of the antenna structure 1 away from the bottom of the mounting slot 41. The sleeve 21 may be inserted into the mounting slot 41, and part of the sleeve 21 may be interference fit with the mounting slot 41 to achieve fixed installation of the antenna structure 1 and the face shell 3. In addition, since the sleeve 21 and the mounting slot 41 are interference fit, the sleeve 21 may be directly withdrawn from the mounting slot 41, so that the antenna structure 1 can be easily removed from the face shell 3 without causing damage to the antenna structure 1. Furthermore, the size range of the interference fit (i.e., unilateral interference) between the sleeve 21 and the mounting groove 41 can be 0.05-0.4 mm, within which the sleeve 21 can be stably assembled with the mounting groove 41 and it will not be too difficult to remove the sleeve 21 from the mounting groove 41. Preferably, the interference fit size between the sleeve 21 and the mounting groove 41 is 0.3 mm.

[0038] In some embodiments, Figure 2 and Figure 3 As shown, the flexible sleeve 2 further includes a matching portion 22 disposed on the outer peripheral wall of the sleeve 21, and at least a portion of the matching portion 22 can extend into the mounting groove 41 and abut against the inner wall of the mounting groove 41, and can even be interference fit, so as to improve the stability of the plug-in fit between the sleeve 21 and the mounting groove 41. In particular, along the direction from the notch of the mounting groove 41 to the groove bottom, the side wall of the mounting groove 41 can be gradually inclined toward the direction close to the matching portion 22, so that an expansion space 6a can be formed between the side wall of the mounting groove 41, the matching portion 22 and the sleeve 21. When the antenna structure 1 expands, the antenna structure 1 simultaneously expands the sleeve 21 sleeved on the antenna structure 1, and the expansion space 6a can provide an escape space for the expanded antenna structure 1 and the sleeve 21 sleeved on the antenna structure, thereby effectively improving the safety of the device 100.

[0039] In some embodiments, Figure 3 As shown, the side of the mating portion 22 that abuts against the side wall of the mounting groove 41 can be set as a slope, and the slope can be adapted to the inclination of the side wall of the mounting groove 41 to play a guiding role in the process of inserting the flexible sleeve 2 into the mounting groove 41, making it more convenient for the flexible sleeve 2 to be plugged in and out of the mounting groove 41.

[0040] In some embodiments, Figure 3 As shown, the other side wall of the mounting groove 41 can be arranged at an angle, and the part of the sleeve 21 away from the bottom of the mounting groove 41 can abut against the side wall of the mounting groove 41 for interference fit, or even interference fit, so as to improve the stability of the plug-in fit between the sleeve 21 and the mounting groove 41; and, an expansion space 6b can be formed between the side wall of the mounting groove 41, the sleeve 21 and the bottom of the mounting groove 41 to provide an escape space for possible expansion of the antenna structure 1, thereby further improving the safety of the device 100.

[0041] In some embodiments, Figure 2 and Figure 3 As shown, the sleeve 21 is removably plugged into the mounting groove 41, and the flexible sleeve 2 also includes a pull-out portion 23 provided on the outer peripheral wall of the sleeve 21. The pull-out portion 23 is pulled to drive the sleeve 21 out of the mounting groove 41, so that the antenna structure 1 can be easily disassembled and repaired. In addition, when the sleeve 21 is inserted into the mounting groove 41, one end of the pull-out portion 23 close to the bottom of the mounting groove 41 abuts against the inner peripheral wall of the face shell 3. Conversely, the open end of the sleeve 21 equipped with the antenna structure 1 is pressed so that the other end of the sleeve 21 opposite to the open end abuts against the bottom of the mounting groove 41 to install it in place. That is, the installation and disassembly of the antenna structure 1 are both convenient and quick.

[0042] In some embodiments, Figure 4 As shown, the flexible sleeve 2 also includes a support foot 24 arranged on the outer peripheral wall of the sleeve 21, and the support foot 24 can abut against the side wall of the surface shell 3 to support the portion of the sleeve 21 extending out of the installation groove 41, thereby further improving the stability of the fixed installation of the antenna structure 1 and the surface shell 3.

[0043] In some embodiments, the sleeve 21, the fitting portion 22, the pull-out portion 23 and the support leg 24 can be an integrally formed structure to ensure the consistency of the product. Furthermore, the flexible sleeve 2 can be made of silicone material, that is, the sleeve, the fitting portion 22, the pull-out portion 23 and the support leg 24 are all made of silicone material. The silicone material has high elasticity and can ensure the buffering and energy absorption effect under extreme working conditions; moreover, the silicone material does not affect the efficiency and function of the antenna structure 1, which is different from the contamination of the antenna structure 1 by the glue dispensing process; in addition, the silicone material can withstand the impact of aging and deterioration under various working conditions, ensuring high reliability during the service life.

[0044] In some embodiments, Figure 4 As shown, the antenna structure 1 includes an electromagnetic inductor core 11 and a coil 12 wound around the electromagnetic inductor core 11. The length of the electromagnetic inductor core 11 may be greater than the length of the coil 12, so that the coil 12 can be placed in the middle part of the electromagnetic inductor core 11, that is, the two ends of the electromagnetic inductor core 11 extend from the two ends of the coil 12 respectively. The electromagnetic inductor core 11 may be cylindrical, and the coil 12 may be cylindrical with two ends through, and the inner diameter of the coil 12 is adapted to the diameter of the electromagnetic inductor core 11, so that the electromagnetic inductor core 11 and the coil 12 can be fixedly connected. The electromagnetic inductor core 11 and the coil 12 are both located in the sleeve 21, and the coil 12 can be interference fit with the inner circumferential wall of the sleeve 21, so that the antenna structure 1 is fixedly connected to the sleeve 21. Furthermore, since the coil 12 can have an interference fit with the inner wall of the sleeve 21, the antenna structure 1 can be directly removed from the sleeve 21, which facilitates replacement or repair of the antenna structure 1. The antenna structure 1 is installed in the mounting groove 41 through the sleeve 21, that is, the antenna structure 1 is not in direct contact with the mounting groove 41, that is, the antenna structure 1 will not be damaged during the removal process.

[0045] In some embodiments, Figure 4 As shown, there may be a gap 7a between the end of the electromagnetic core 11 and the sleeve 21 in the radial direction to provide a space for the electromagnetic core 11 to expand in the radial direction, thereby further improving the safety of the device 100.

[0046] In some embodiments, Figure 4 As shown, one side of the face shell 3 may have an opening, and the opening of the face shell 3 is arranged opposite to the side wall of the face shell 3. The device 100 also includes a bottom plate 5 covering the opening of the face shell 3, and the bottom plate 5 is detachably connected to the face shell 3, so that when the face shell 3 and the bottom plate 5 are in a released state, it is convenient to install various components of the device 100 that need to be installed in the inner cavity 31 of the face shell 3. Of course, in other embodiments, the bottom plate 5 and the face shell 3 can also be an integrally formed structure. A bone position 51 may be provided on one side of the bottom plate 5 close to the face shell 3, and the bone position 51 may be located at one end of the electromagnetic induction core 11 away from the bottom of the installation groove 41, and there may be a gap 7b between the bone position 51 and the end of the electromagnetic induction core 11 in the axial direction, so as to provide a space for avoiding the expansion phenomenon that may occur in the axial direction of the electromagnetic induction core 11, and further improve the safety of the device 100. Furthermore, the distance range of the gap 7b between the electromagnetic induction core 11 and the bone position 51 can be 0.05-0.2 mm. Within this range, sufficient avoidance space is reserved between the bone position 51 and the electromagnetic induction core 11, and the bone position 51 can limit the electromagnetic induction core 11. Preferably, the gap 7b between the electromagnetic induction core 11 and the bone position 51 is 0.1 mm.
