Description

Technical Field

[0001] This utility model relates to the field of automotive parts technology, and in particular to an adjustable license plate mounting bracket. Background Technology

[0002] A license plate frame is a detachable automotive accessory attached to the front or rear of a vehicle frame to secure the license plate. Due to its ease of installation and removal, it is popular with consumers. Existing license plate frames include a housing, a mounting arm, a drive slider, and a claw assembly. The mounting arm, located on one side of the housing, is used to install the license plate. The claw assembly includes two clamping claws rotatably connected to the mounting arm. When the drive slider moves back and forth, it causes the two clamping claws to move closer or further apart, thereby securing the license plate frame to the vehicle frame or removing it from the frame. However, existing license plate frames rely on two rotatably connected clamping claws on the mounting arm to hold the license plate frame in place. These claws are prone to insecure gripping and easily come loose. Utility Model Content

[0003] The purpose of this utility model is to provide an adjustable license plate mounting bracket to solve the problem that existing license plate brackets, which use two rotatably connected clamping claws on the mounting arm to fix the license plate bracket to the vehicle frame, are not secure and are prone to loosening.

[0004] This utility model is achieved through the following technical solution:

[0005] An adjustable license plate mounting bracket includes a base shell, a fixed arm, a movable arm, a driving mechanism, and a locking mechanism. The fixed arm is connected to the base shell, and the movable arm is rotatably connected to both the fixed arm and the driving mechanism. The movable arm is driven by the driving mechanism to rotate around the connection point between the movable arm and the fixed arm, moving closer to or away from the fixed arm. The locking mechanism is used to restrict the driving mechanism from driving the movable arm to rotate.

[0006] Furthermore, the fixed arm includes a base arm, an adjusting arm, and a fastener. The base arm is connected to the base shell, the adjusting arm can move up and down along the base arm to adjust the distance between the adjusting arm and the base shell, and the fastener is provided on the adjusting arm to lock the adjusting arm onto the base arm.

[0007] Furthermore, one of the base arm and the adjusting arm is provided with a guide groove extending vertically, and the other of the two is provided with a guide strip that slides in cooperation with the guide groove.

[0008] Furthermore, the guide strip is provided with a plurality of adjustment holes, which are spaced apart vertically. One end of the fastener is screwed into any one of the adjustment holes, and the other end abuts against the opening of the guide groove.

[0009] Furthermore, there are two fixed arms and two movable arms, each corresponding to the other, with the two fixed arms arranged opposite each other on the base shell.

[0010] Furthermore, the driving mechanism includes a driving rod, a sliding seat, and a knob. The driving rod is rotatably connected to the base shell and one end is connected to the knob located outside the base shell. The sliding seat is located on the driving rod and is rotatably connected to the movable arm. When the driving rod rotates, it drives the sliding seat to move along it, causing the sliding seat to drive the movable arm to rotate.

[0011] Furthermore, the base shell has a receiving cavity for accommodating the drive rod and the sliding seat, and the movable arm has a first arm and a second arm. The first arm is rotatably connected to the fixed arm and located outside the receiving cavity, and the second arm is disposed on the first arm and extends into the receiving cavity and is rotatably connected to the sliding seat.

[0012] Furthermore, the base shell has a communication port for the second arm to extend into the accommodating cavity, the communication port extending front and rear, and the second arm abutting against the rear wall of the communication port when the movable arm rotates.

[0013] Furthermore, the locking mechanism includes a lock head, a rocker arm, and a locking tooth. The locking tooth passes through the drive rod. The rocker arm is rotatably connected to the base shell, and one end of the rocker arm engages with the locking tooth. The lock head can rotate relative to the base shell to abut against or release the rocker arm. When the lock head abuts against the rocker arm, the rocker arm restricts the rotation of the drive rod.

[0014] Furthermore, the base shell is provided with an elastic element that engages one end of the rocker arm with the locking tooth.

[0015] The advantage of this technical solution is that by configuring a fixed arm, a driving mechanism, and a locking mechanism on the base shell, and configuring a movable arm on the fixed arm, the movable arm is rotatably connected to the fixed arm and the driving mechanism respectively and is driven by the driving mechanism to move closer to or away from the fixed arm. The locking mechanism restricts the driving mechanism from driving the movable arm to rotate, and the relative position of the fixed arm and the movable arm is stable, so that the adjustable license plate mounting bracket has good clamping stability and is not easy to loosen.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Example: Figure 1-8As shown, the adjustable license plate mounting bracket includes a base shell 1, a fixed arm 2, a movable arm 3, a driving mechanism 4, and a locking mechanism 5. The fixed arm 2 is connected to the base shell 1. The movable arm 3 is rotatably connected to both the fixed arm 2 and the driving mechanism 4. The movable arm 3 is driven by the driving mechanism 4 to rotate around the connection point between the movable arm 3 and the fixed arm 2, moving closer to or away from the fixed arm 2. The locking mechanism 5 is used to restrict the driving mechanism 4 from driving the movable arm 3 to rotate or to release the driving mechanism 4 so that it can drive the movable arm 3 to rotate. Specifically, when the movable arm 3 rotates closer to the fixed arm 2, it cooperates with the fixed arm 2 to clamp and fix the adjustable license plate mounting bracket to the vehicle frame. When the movable arm 3 rotates away from the fixed arm 2, it releases the adjustable license plate mounting bracket. This embodiment provides an adjustable license plate mounting bracket to solve the problem that existing license plate brackets, which use two rotatably connected clamping claws on mounting arms to fix the license plate bracket to the vehicle frame, are not secure and are prone to loosening. The main solution is to configure a fixed arm 2, a driving mechanism 4, and a locking mechanism 5 on the base shell 1. A movable arm 3 is configured on the fixed arm 2. The movable arm 3 is rotatably connected to the fixed arm 2 and the driving mechanism 4, and is driven by the driving mechanism 4 to move closer to or away from the fixed arm 2. The locking mechanism 5 restricts the relative position of the fixed arm 2 and the movable arm 3 from rotating when the driving mechanism 4 drives the movable arm 3. This ensures that the adjustable license plate mounting bracket has good clamping stability and is not prone to loosening.

[0028] In this embodiment of the invention, the fixed arm 2 includes a base arm 201, an adjusting arm 202, and a fastener 203. The base arm 201 is connected to the base shell 1. The adjusting arm 202 can move up and down along the base arm 201 to adjust the distance between the adjusting arm 202 and the base shell 1. The fastener 203 is provided on the adjusting arm 202 to lock the adjusting arm 202 onto the base arm 201. The adjusting arm 202 is used to install the license plate. By configuring the fixed arm 2 as a base arm 201 on the base shell 1 and an adjusting arm 202 that can move up and down along the base arm 201, the adjustable license plate mounting bracket can adapt to license plates of different heights or adjust the license plate to different heights, making it flexible and highly adaptable.

[0029] In this embodiment of the invention, the adjusting arm 202 is provided with a vertically extending guide groove 204, and the base arm 201 is provided with a guide bar 205 that slides in cooperation with the guide groove 204. This arrangement, by configuring the guide groove 204 on the adjusting arm 202 and the guide bar 205 on the base arm 201, ensures stable and smooth vertical movement of the adjusting arm 202.

[0030] In other embodiments, the guide groove 204 is disposed on the base arm 201, and the guide bar 205 is disposed on the adjusting arm 202.

[0031] In this embodiment of the invention, the guide strip 205 is provided with a plurality of adjusting holes 206, which are spaced apart vertically. One end of the fastener 203 is screwed into any adjusting hole 206, and the other end abuts against the opening of the guide groove 204. This arrangement, by configuring a plurality of adjusting holes 206 on the guide strip 205, with the holes spaced apart vertically, and one end of the fastener 203 screwed into any adjusting hole 206 and the other end abutting against the opening of the guide groove 204, allows the adjusting arm 202 to be fixed at different heights on the base arm 201. The adjusting and fixing structure is simple and easy to implement.

[0032] In this embodiment of the invention, there are two fixed arms 2 and two movable arms 3, which correspond one-to-one. The two fixed arms 2 are arranged opposite to each other on the base shell 1. By configuring two fixed arms 2 and two movable arms 3, and arranging the two fixed arms 2 opposite to each other on the base shell 1, the adjustable license plate mounting bracket is clamped / assembled stably.

[0033] In this embodiment of the invention, the driving mechanism 4 includes a driving rod 401, a sliding seat 402, and a knob 403. The driving rod 401 is rotatably connected to the base shell 1, and one end is connected to the knob 403 located outside the base shell 1. The driving rod 401 is driven by the knob 403. The sliding seat 402 is located on the driving rod 401 and rotatably connected to the movable arm 3. When the driving rod 401 rotates, it drives the sliding seat 402 to move along it, causing the sliding seat 402 to drive the movable arm 3 to rotate. By configuring the driving mechanism 4 as a driving rod 401, a sliding seat 402, and a knob 403, the movable arm 3 is driven to rotate by the sliding seat 402 when the driving rod 401 rotates. The driving structure is simple and easy to implement.

[0034] In this embodiment of the invention, the locking mechanism 5 includes a lock head 501, a rocker arm 502, and a locking tooth 503. The locking tooth 503 passes through the drive rod 401 and is fixed relative to the drive rod 401. The rocker arm 502 is rotatably connected to the base shell 1, and one end engages with the locking tooth 503. The lock head 501 can rotate relative to the base shell 1 to abut against or release the rocker arm 502. When the lock head 501 abuts against the rocker arm 502, the rocker arm 502 restricts the rotation of the drive rod 401. The end of the lock head 501 away from the rocker arm 502 is exposed in the base shell 1 and has a keyhole. When the user inserts a key, the lock head 501 rotates, and when the lock head 501 abuts against the rocker arm 502, the rotation of the drive rod 401 is restricted, thus locking the movable arm 3. When the user inserts the key, it rotates the lock head 501, causing the lock head 501 to release the rocker arm 502, thus unlocking the movable arm 3. The locking structure is simple and easy to implement.

[0035] In this embodiment of the utility model, the base shell 1 is provided with an elastic element 504 that allows one end of the rocker arm 502 to engage with the locking tooth 503.

[0036] In this embodiment of the invention, the base shell 1 has a cavity 101 for accommodating the drive rod 401 and the sliding seat 402. The movable arm 3 has a first arm 301 and a second arm 302. The first arm 301 is rotatably connected to the fixed arm 2 and located outside the cavity 101. The second arm 302 is disposed on the first arm 301 and extends into the cavity 101, rotatably connected to the sliding seat 402. This configuration, by arranging the base shell 1 with a cavity 101 for accommodating the drive rod 401 and the sliding seat 402, and arranging the movable arm 3 with a first arm 301 rotatably connected to the fixed arm 2 and a second arm 302 disposed on the first arm 301 and extending into the cavity 101, rotatably connected to the sliding seat 402, ensures that the base shell 1, drive rod 401, sliding seat 402, and movable arm 3 are assembled compactly and rotate smoothly.
