Description

Technical Field

[0001] The utility model belongs to the field of daily necessities, and in particular relates to a vehicle-mounted bracket. Background Art

[0002] Currently, people often do not know the road when driving or riding a bicycle, and need electronic equipment for navigation, or need to occasionally look at the screen of an electronic device. For convenience, people often install a vehicle bracket on the air outlet of the car or on the handlebars of a motorcycle to fix mobile phones or other electronic devices.

[0003] Usually, the vehicle bracket is fixed to the air outlet of the car by extending the moving part of the vehicle bracket into the air outlet and pulling the moving part outward by rotating the adjustment button until the adjustment blade of the air outlet is clamped. Since users are often unsure whether the adjustment blade is clamped, they will still rotate the adjustment button hard after clamping. The vehicle bracket is usually made of hard plastic material. If the force is continued after clamping, it is easy to damage the parts between the rotating button and the clamping piece, resulting in damage to the vehicle bracket. Utility Model Content

[0004] The technical purpose of the utility model is to provide a vehicle-mounted bracket, which aims to prevent the bracket from being damaged even if the user continues to rotate and tighten it after the bracket is fixed.

[0009] The moving part, at least part of which is located in the accommodating space, is arranged at intervals with the transmission shaft along the radial direction of the transmission shaft, a matching portion is provided on the moving part, and the matching portion matches with the first thread, so that the rotating assembly drives the moving part to reciprocate along the axial direction by rotating, and a connecting portion is provided at one end of the moving part, the connecting portion is located outside the housing, and the connecting portion is configured to achieve fixed connection with an external fixing device through linear motion;

[0010] The clamping end is elastic, and the elasticity of the clamping end is configured such that: when the moving part can move linearly, the rotating part and the transmission shaft are fixedly connected; when the moving part is limited in one direction by an external fixing device, the rotating part is rotated in the original direction, and the clamping end is deformed, so that the clamping end is idle relative to the accommodating cavity, and the rotating part and the transmission shaft are rotationally connected;

[0011] The connecting piece is rotatably connected to the shell, and one end of the connecting piece is used to connect to an external mobile device.

[0012] In one embodiment, the first thread is an external thread.

[0013] In one embodiment, the matching portion is a plurality of matching grooves arranged at intervals along the axial direction, and a partial area of ​​the external thread is located in the matching groove.

[0014] In one of the embodiments, the rotating member is provided with a receiving cavity, the transmission shaft is provided with a clamping end, and the diameter of the transmission shaft is smaller than the diameter of the rotating member.

[0015] In one embodiment, a moving part with a first thread located in the accommodating space is provided with a limiting portion, and the limiting portion is located between the end of the first thread away from the connecting portion and the rotating part. From the perspective along the axial direction, at least parts of the limiting portion, the first thread, and the rotating part overlap to limit the linear motion range of the moving part.

[0016] In one embodiment, two recessed grooves are provided on the rotating member so that a rotating force can be applied thereto by hand.

[0017] In one embodiment, the connecting piece is sleeved on the outer circumference of the shell, and the inner wall of the connecting part is provided with internal teeth surrounding the outer circumference of the shell, and the internal teeth include gear teeth and tooth grooves;

[0020] In one embodiment, the main body of the locking member is oval and sleeved on the rotating assembly. The locking member is elastic to drive the reciprocating movement of the first protrusion.

[0021] In one of the embodiments, a second protrusion is provided on one side of the shell facing the connecting portion, the connecting portion is hook-shaped, and the connecting portion and the second protrusion surround a limiting cavity, which is used for sleeve installation of an external fixing device.

The rotating part drives the transmission shaft to rotate through the cooperation of the clamping end and the receiving cavity. The matching part on the moving part is converted into the linear motion of the matching part along with the rotational motion of the first thread, thereby driving the moving part to move linearly. Since the clamping end is elastic, when the moving part fixes the fixed equipment on the vehicle, the moving part can no longer move. If the rotating part continues to rotate, the clamping end will be deformed and rotate relative to the receiving cavity. Therefore, the rotating part will idle relative to the transmission shaft, and will not continue to force the transmission shaft to rotate, thereby damaging the connection between the transmission shaft and the moving part, and even damaging the vehicle bracket and the regulating blades of the car air outlet. The vehicle bracket provided by the present application is of higher quality and more durable. BRIEF DESCRIPTION OF THE DRAWINGS

[0035] See also Figures 1 to 3 , Figure 1 A schematic structural diagram of the vehicle bracket provided in this application is shown. Figure 2 A half-section view of the vehicle mount is shown. Figure 3 The schematic diagram of the structure of the internal accommodation space of the housing 100 is shown. The present application provides a vehicle-mounted bracket, which can fix an electronic device in a vehicle, so that a user can see information on the electronic device without lowering his head in the vehicle.

[0036] Specifically, the vehicle bracket includes: a housing 100, a rotating assembly 200, a moving part 300 and a connecting member 400, wherein the housing 100 has a receiving space for receiving at least part of the structure of the rotating assembly 200 and the connecting member 400, the rotating assembly 200 includes a rotating member 210 and a transmission shaft 220, the rotating member 210 is rotatably connected to the housing 100, the transmission shaft 220 is located in the receiving space, and the outer peripheral surface of the transmission shaft 220 is provided with a first thread 221 extending along the axial direction;

[0037] See also Figure 4 and Figure 5 , Figure 4 Shows the view from the side of the rotating part facing the drive shaft. Figure 5 The schematic diagram of the structure of the transmission shaft is shown. A accommodating cavity 211 is provided at one end of the rotating member 210 close to the transmission shaft, and a clamping end 222 is provided at one end of the transmission shaft close to the rotating member, and the clamping end 222 extends into the accommodating cavity 211; along the radial direction of the transmission shaft, the moving member 300 and the rotating assembly 200 are arranged at intervals, and a matching portion 310 is provided on the moving member 300, and the matching portion 310 matches with the first thread 221, so that the rotating assembly 200 drives the moving member 300 to reciprocate along the axial direction by rotation, and the clamping end 222 is elastic, and the elasticity of the clamping end 222 is configured as follows: when the moving member is limited in one direction by an external fixing device, the rotating member is rotated in the original direction, and the clamping end 222 will be deformed, so that the clamping end 222 rotates relative to the accommodating cavity 211.

[0038] The connecting member 400 is rotatably connected to the housing 100 , and one section of the connecting member 400 is used to connect to an external mobile device, such as a mobile phone or a Pad.

[0039] In the above embodiment, the rotating assembly 200 and the moving part 300 actually generate a thread transmission, and the thread realizes the transformation from rotational motion to linear motion. Since the thread is a spiral extension, it provides a thrust for linear motion of the moving part 300 when rotating. The moving part 300 is provided with a connecting portion 320 at one end. The connecting portion 320 is located outside the housing 100. The connecting portion 320 is configured to be fixedly connected to an external fixing device. Usually, the connecting portion 320 is hook-shaped, see Figure 1 Generally, the user extends the connection part 320 into the air outlet and hooks the adjusting blade with the hook-shaped connection part 320. When the moving part 300 and the adjusting blade are fixed, the moving part 300 is restricted by the adjusting blade and can no longer continue to move in a straight line. At this time, since the clamping end 222 is elastic and the inner wall shape of the accommodating cavity 211 is also a curved shape, the clamping end 222 will be deformed. At this time, the transmission shaft of the rotating part will not continue to rotate, that is, idling occurs, and the vehicle damage bracket and the adjusting blade of the automobile air outlet cannot be damaged.

[0040] When the vehicle bracket needs to be removed from the regulating blade of the air outlet, the rotating assembly 200 only needs to be rotated in the opposite direction. Since the moving part 300 is not restricted by the regulating blade, the reverse rotating rotating part 210 will continue to push the moving part 300 to move in the opposite direction without generating idling.

[0041] In other embodiments, a clamping end 222 may be provided on the rotating member, and a receiving end for receiving the clamping end 222 may be provided on the transmission shaft.

[0042] Preferably, the inner wall shape of the accommodating cavity 211 is as follows: Figure 4The plum blossom-shaped figure shown has a larger curvature radius but can drive the clamping end 222 to rotate at the same time. The shape of the inner wall can also be set to other figures with a larger curvature radius, but it cannot be a circle.

[0043] In other embodiments, the inner wall shape may also be a straight line figure with a larger inner angle, where the larger angle refers to an angle greater than 150° and less than 180°. Because the smaller angle means that even if the clamping end 222 is deformed, it will not rotate relative to the accommodating cavity 211.

[0044] For details, see Figure 5 In one embodiment, the first thread 221 is an external thread. Usually, the outer surface is externally threaded, such as a screw, and the inner surface is internally threaded, such as a nut. Compared with the internal thread, the external thread is protruding from the outer surface of the rotating component 200. As an active part, the processing cost of the external thread is lower.

[0045] See also Figure 6 , Figure 6 The figure shows the matching relationship between the rotating assembly and the moving part. In one embodiment, the matching portion 310 is a plurality of matching grooves arranged at intervals along the axial direction, and the external thread part area is located in the matching groove. The matching groove is used to accommodate the external thread, and the external thread will push the matching groove to move, thereby driving the movement of the moving part 300. Figure 3 As can be seen from the figure, the matching groove can be a slot hole that penetrates the thickness direction of the moving part 300. Compared with the internal thread, the matching groove is easier to process for the plate-shaped moving part 300.

[0046] In some other embodiments, the matching portion 310 may be a nut sleeved on an external thread, in which case it becomes a nut-screw transmission pair, and the moving part 300 and the nut may be rotationally matched, so that the rotation of the nut will not cause the moving part 300 to rotate, and the linear motion of the nut may drive the moving part 300 to move linearly. Alternatively, in other embodiments, the matching portion may be an internal thread that matches the external thread, and of course, when the first thread is an internal thread, the matching portion is an external thread that matches the internal thread.

[0047] Preferably, see Figure 6 The diameter of the transmission shaft 220 is smaller than that of the rotating member 210. The rotating member 210 is located outside the housing 100 and has a larger diameter for convenient rotation by the user. The transmission shaft 220, as a main transmission component, needs to be protected in the accommodation space of the housing 100.

[0048] See also Figure 6In one embodiment, the moving part 300 in the accommodation space is provided with a limit portion 330, which is located between the end of the first external thread away from the connecting part 320 and the rotating part 210. From the perspective of the axial direction, the limit portion 330, the external thread, and the rotating part 210 at least partially overlap to limit the linear motion range of the moving part 300. Figure 2 or Figure 4 It can be seen that when the limiting portion 330 moves linearly toward the outside of the shell 100, it will hit the first thread 221, and when moving into the shell 100, it will hit the rotating member 210. Therefore, the rotating member 210 and the first thread 221 will limit the movement range of the moving member 300 through the limiting portion 330 to prevent the moving member 300 from completely extending out of the shell 100.

[0049] Preferably, see Figure 6 In one embodiment, two recessed grooves 212 are provided on the rotating member 210 , so that the user can rotate the rotating member 210 by pinching the rotating member 210 with fingers. The pinching action is more labor-saving and convenient than holding the circular surface of the rotating member 210 with fingers.

[0050] See also Figure 7 , Figure 7 The matching relationship between the connecting part 320 and the housing 100 is shown. In one embodiment, the connecting member 400 is sleeved on the outer circumference of the housing 100, and the inner wall of the connecting part 320 is provided with an inner tooth 410 that surrounds the outer circumference of the housing 100, and the inner tooth 410 includes a gear tooth 411 and a tooth groove 412. The inner side of the housing 100 away from the connecting part 320 is provided with a retaining member 500, and the housing 100 is provided with a notch, and the retaining member 500 is provided with a first protrusion 510, which extends out of the notch and extends into the tooth groove 412. The first protrusion 510 can slide relative to the surface of the gear tooth 411 and the tooth groove 412.

[0051] Specifically, in one embodiment, the main body of the locking member 500 is oval and sleeved on the rotating assembly 200 . The locking member 500 is elastic to drive the reciprocating movement of the first protrusion 510 .

[0052] The above embodiment shows how the connection part 320 rotates relative to the housing 100. In order to facilitate the user to adjust the angle, the connection part 320 not only needs to be able to rotate autonomously, but also needs to be supported by the housing 100 after rotation so as to be in a stationary state relative to the housing 100. Figure 7 A circle of internal teeth 410 is provided on the inner wall of the connecting part 320, wherein the gear teeth 411 abut against the outer peripheral surface of this part of the shell 100, and the main structure of the shell 100 and the rotating member 210 sandwich the connecting part 320 in the middle, thereby limiting the linear movement of the connecting part 320 and only allowing the connecting part 320 to rotate. Figure 7It can be seen that there is a retaining member 500 inside the shell 100, and there is a notch on the shell 100. The retaining member 500 extends a first protrusion 510 from the notch, and the first protrusion 510 extends into the tooth groove 412. Since the first protrusion 510 cannot rotate, the first protrusion 510 limits the rotation of the connecting part 320.

[0053] The main body of the locking member 500 is elastic, so when a person uses external force to forcibly rotate the connecting member 400, the inner teeth 410 of the connecting member 400 will push the first protrusion 510, and the first protrusion 510 will cause the locking member 500 to deform, so that the first protrusion 510 gradually retreats into the notch, which is reflected in the inner teeth 410 as the first protrusion 510 sliding relative to the tooth groove 412 and the surface of the gear teeth 411. When the connecting member 400 rotates one tooth pitch, the first protrusion 510 will return to the tooth groove 412 to complete the locking due to the rebound force of the locking member 500, and the connecting member 400 stops rotating. Therefore, the user can control the rotation angle of the connecting member 400 according to their own needs, and the weight of the electronic device is not enough to cause the locking member 500 to deform, so it will not drive the connecting part 320 to rotate.

[0054] See also Figure 1 In one embodiment, the housing 100 is provided with a second protrusion 110 on one side facing the connection portion 320, the connection portion 320 is hook-shaped, and the connection portion 320 and the second protrusion 110 enclose a limiting cavity, and the limiting cavity is used to set an external fixing device. The adjusting blade is plate-shaped, so if there is no second protrusion 110, the adjusting blade may slip out of the hook-shaped connection portion 320, thereby making the vehicle bracket unstable.

[0055] See also Figure 1 In one embodiment, the connector 400 is provided with a universal ball 420, which is used to connect an external clamping device. The universal ball 420 has a rotational freedom relative to the connector 400 body, and can be conveniently connected to the external clamping device, which is used to fix electronic devices such as mobile phones or pads.

[0056] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
