Description

Technical Field

[0001] This invention relates to the field of automotive spring button assembly technology, specifically to an automotive key spring button assembly tool. Background Technology

[0002] In automotive design, some cars use a folding key design, where the key pops out of the remote control by pressing a spring button. During assembly, the remote control and the key need to be connected via the spring button. This assembly process mainly involves manually pushing the spring button directly into the connection hole with considerable force. This makes the spring button assembly time-consuming and labor-intensive, resulting in high worker workload, difficulty in assembly, and a high risk of damaging the spring button, leading to low efficiency. Summary of the Invention

[0003] The purpose of this invention is to improve and innovate upon the shortcomings and problems existing in the prior art, and to provide a tool for assembling a car key spring button.

[0004] To achieve the above objectives, the present invention provides the following technical solution: a car key spring button assembly tool, comprising a base, a bracket provided on one side of the upper surface of the base, a pressure rod support block provided at the upper end of the bracket, a pressure rod and a second rotating rod inserted perpendicularly to each other on the pressure rod support block, a pressure rod head provided at the bottom end of the pressure rod, an operating long handle fixedly connected to the end of the second rotating rod, a gear installed in the middle of the second rotating rod, the gear meshing with the gear teeth provided on the outer surface of the pressure rod, a sliding plate fixedly connected to the upper end of the pressure rod and fitted with a spring, the sliding plate compressing the spring along the pressure rod, a first adjusting mechanism for adjusting the spring compression amount provided on one side of the pressure rod, the upper and lower ends of the spring being fixedly connected to the sliding plate and the pressure rod support block respectively, and a key positioning block provided on the base, the key positioning block having a positioning groove adapted to the car key, the positioning groove being located directly below the pressure rod head.

[0005] As can be seen from the above technical solution, the present invention drives the gear to rotate by rotating the long operating handle, thereby driving the pressure rod head to move downward and press the spring button. The manual pressing force on the spring button is converted into the torque that drives the long operating handle to rotate. The torque that drives the long operating handle to rotate can be significantly reduced by extending the length of the long operating handle, making the spring button assembly time-saving and labor-saving. The assembly process is simple and easy to implement, and the assembly efficiency is high. At the same time, different spring buttons can be installed for different car model keys.

[0006] A further embodiment is that the first adjustment mechanism includes a first lead screw mounted on the pressure rod support block, a nut and a slider threaded onto the first lead screw, and the first lead screw passes through one side of the sliding plate. A second through groove is provided on the sliding plate for the first lead screw to pass through. The nut and the slider are respectively located on the upper and lower sides of the sliding plate. A fixing sleeve is installed at the bottom end of the pressure rod, and the pressure rod head is inserted into the fixing sleeve. A second adjustment mechanism is provided on the fixing sleeve for adjusting the height of the pressure rod head relative to the key positioning block.

[0007] As can be seen from the above technical solution, since the travel range of the spring button in car keys of different models is consistent, but the pressing force of the spring button is different, by adjusting the position of the slider relative to the sliding plate and correspondingly adjusting the height of the pressure rod head relative to the key positioning block, the travel range of the sliding plate is changed without changing the travel range of the pressure rod head driving the spring button, thereby changing the compression of the spring sleeved on the pressure rod. This makes the pressing force of the pressure rod head on the spring button consistent with the pressing force required by the spring button, avoiding excessive or insufficient pressing force of the pressure rod head on the spring button. This is suitable for assembling car keys of different models, thereby improving the applicability of the device. The greater the pressing force required by the spring button, the smaller the corresponding spring compression.

[0008] A further embodiment is that the second adjustment mechanism includes a first connecting plate mounted on the outer wall of the fixed sleeve, a double-headed motor mounted on the first connecting plate, a first rotating rod and a second lead screw respectively fixedly connected to the output ends of the double-headed motor, a second connecting plate fixedly connected to the outer surface of the pressure rod head, the middle part of the second lead screw passing through the second connecting plate and threadedly connected thereto; the first lead screw is rotatably connected to the pressure rod support block via a bearing, the bottom end of the first lead screw slides in cooperation with the end of the first rotating rod away from the double-headed motor through a groove, a limit groove is provided on the side wall of the groove, and the limit groove slides in cooperation with the ribs provided on the outer surface of the first rotating rod, a guide rod is fixedly connected to the upper surface of the pressure rod support block, the guide rod passes through one side of the slider and slides in cooperation thereto, the lead of the first lead screw and the second lead screw are equal.

[0009] As can be seen from the above technical solution, by simultaneously driving the first rotating rod and the second lead screw with a dual-head motor, and since the lead of the first lead screw and the second lead screw are equal, it is convenient to synchronously drive the slider and the pressure rod head to move in opposite directions at the same distance. This serves to simultaneously adjust the spring compression and the distance of the pressure rod head relative to the key positioning block, avoiding the cumbersome operation and inconvenience of ensuring that the position changes of the slider and the pressure rod head are consistent when adjusting the position of the slider and the pressure rod head separately. At the same time, through the cooperation of the first lead screw, the first rotating rod, the rib and the limiting groove, it will not interfere with the downward movement of the pressure rod head to press the spring button by rotating the long handle to drive the gear to rotate. In addition, through the cooperation of the first connecting plate, the dual-head motor, the second lead screw, the fixed sleeve, the second connecting plate and the pressure rod head, it not only supports the pressure rod head, but also adjusts the length of the pressure rod head extending into the fixed sleeve.

[0010] A further option is to provide a first through slot on the first connecting plate for the passage of the first rotating rod.

[0011] A further solution is to have one side of the sliding plate slide in conjunction with the guide rod, which acts as a guide to ensure smooth up-and-down movement of the sliding plate. This facilitates smooth up-and-down movement of the pressure rod head, accurately pressing the spring button into the corresponding connection hole of the key.

[0012] A further design involves an L-shaped guide rod, with the top of the first lead screw rotatably connected to the guide rod via a bearing.

[0013] A further solution is to fix a limiting plate to the bottom end of the second lead screw.

[0014] A further design involves having four ribs arranged in a circular array along the central axis of the first rotating rod.

[0015] A further solution is to make the key positioning block from plastic, so that the key positioning block is less likely to damage the car key when it is embedded in the positioning groove.

[0016] A further embodiment involves a second rotating rod rotatably connected to a pressure rod support block via a bearing. A torsion spring is fitted onto the pressure rod support block, with one end of the torsion spring fixedly connected to the support block. The torsion spring is used to reset and limit the second rotating rod, allowing it to return to its initial position.

[0017] Compared with the prior art, the beneficial effects of the present invention are: (1) The present invention drives the gear to rotate by rotating the long handle, thereby driving the pressure rod head to move downward and press the spring button, converting the manual pressing force of the spring button into the torque that drives the long handle to rotate. The torque that drives the long handle to rotate can be significantly reduced by extending the length of the long handle, making the spring button assembly time-saving and labor-saving, the assembly process simple and easy to implement, and the assembly efficiency high.

[0018] (2) Since the travel range of the spring button of different car key models is the same, but the pressing force of the spring button is different; by adjusting the position of the slider relative to the sliding plate and the corresponding adjustment of the height of the pressure rod head relative to the key positioning block, the travel range of the sliding plate is changed without changing the travel range of the pressure rod head driving the spring button, thereby changing the compression of the spring sleeved on the pressure rod, so that the pressing force of the pressure rod head on the spring button is consistent with the pressing force required by the spring button, avoiding the pressing force of the pressure rod head on the spring button being too large or too small, which is suitable for assembling car keys of different models, thereby improving the applicability of the device.

[0019] (3) The first rotating rod and the second lead screw are driven simultaneously by the dual-head motor. Since the lead of the first lead screw and the second lead screw are equal, it is convenient to drive the slider and the pressure rod head to move in opposite directions at equal distances. This can simultaneously adjust the spring compression and the distance of the pressure rod head relative to the key positioning block. This avoids the cumbersome operation and inconvenience of adjusting the position of the slider and the pressure rod head separately, which makes it difficult to ensure that the position changes of the slider and the pressure rod head are consistent. At the same time, the cooperation of the first lead screw, the first rotating rod, the rib and the limiting groove will not interfere with the rotation of the long handle to drive the gear to rotate and drive the pressure rod head to move downward to press the spring button. In addition, the cooperation of the first connecting plate, the dual-head motor, the second lead screw, the fixed sleeve, the second connecting plate and the pressure rod head can both support the pressure rod head and adjust the length of the pressure rod head extending into the fixed sleeve.

Detailed Implementation

[0027] To make the objectives, features, and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0028] It should be noted that when a component is said to be "fixed to" another component, it can be directly on the other component or there may be an intervening component. When a component is said to be "connected to" another component, it can be directly connected to the other component or there may be an intervening component.

[0029] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein in the description of the invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0030] See Figures 1-5 A car key spring button assembly tool includes a base 1, which provides support for the entire tool. The base 1 is made of steel. From left to right, a key positioning block 4 and a bracket 5 are arranged on the upper surface of the base 1. The key positioning block 4 has a positioning groove 401 adapted to the car key, which is used to fix the car key. The key positioning block 4 is made of plastic. It is understood that when the car key is embedded in the positioning groove 401, the plastic key positioning block 4 is less likely to damage the car key.

[0031] A pressure rod support block 2 is provided at the upper end of the bracket 5. A pressure rod 301 and a second rotating rod 212 are inserted into the pressure rod support block 2, which are perpendicular to each other. The pressure rod 301 is vertically arranged. A cavity is opened inside the pressure rod support block 2. The second rotating rod 212 is rotatably connected to the front and rear side walls of the cavity through bearings. A torsion spring is sleeved on the pressure rod support block 2. One end of the torsion spring is fixedly connected to the front and rear side walls of the cavity. The end of the second rotating rod 212 passes through the side wall of the cavity and is fixedly connected to an operating long handle 201. A gear 213 is provided in the middle of the second rotating rod 212 located in the cavity. The gear 213 meshes with the gear teeth provided on the outer surface of the pressure rod 301 located in the cavity. It can be understood that with this arrangement, when the operating long handle 201 is held to drive the second rotating rod 212 to rotate, the pressure rod 301 will move up and down.

[0032] One end of the pressure rod 301 penetrates the top wall of the cavity and extends upward, where it is fixedly connected to a sliding plate 3. A spring 302 is also fitted onto the spring 301. The upper and lower ends of the spring 302 are fixedly connected to the sliding plate 3 and the pressure rod support block 2, respectively. A first lead screw 202 and a guide rod 203 are sequentially arranged on one side of the pressure rod 301. The first lead screw 202 is rotatably connected to the pressure rod support block 2 via a bearing. The guide rod 203 is fixedly connected to the pressure rod support block 2. A nut 204 and a slider 205 are threaded onto the first lead screw 202. A lead screw 202 passes through one side of the sliding plate 3. The sliding plate 3 has a second through groove for the lead screw 202 to pass through, so that the thread on the lead screw 202 will not interfere with the sliding plate 3 moving up and down along the central axis of the lead screw 202. The nut 204 and the slider 205 are respectively provided on the upper and lower sides of the sliding plate 3. The nut 204 and the slider 205 respectively limit the range of the up and down movement of the sliding plate 3. The sliding plate 3 and the slider 205 are both slidably engaged with the guide rod 203 by opening sliding holes.

[0033] The bottom end of the pressure rod 301 extends downward through the pressure rod support block 2 and is fitted with a fixing sleeve 303. A pressure rod head 304 is inserted into the fixing sleeve 303, and the outer surface of the pressure rod head 304 slides in contact with the inner surface of the fixing sleeve 303. The fixing sleeve 303 is provided with a second adjustment mechanism for adjusting the height of the pressure rod head 304 relative to the key positioning block 4. The second adjustment mechanism includes a first connecting plate 206 installed on the outer wall of the fixing sleeve 303. A dual-head motor 207 is installed on the first connecting plate 206. The output ends of the dual-head motor 207 are respectively fixedly connected to a first rotating rod 210 and a second lead screw 208. A first through groove 209 is provided on the first connecting plate 206 for the first rotating rod 210 to pass through. A second connecting plate 216 is fixedly connected to the outer surface of the pressure rod head 304. The middle part of the second lead screw 208 passes through the second connecting plate 216 and is threadedly connected to it. The bottom end of the first lead screw 202 is slidably engaged with the end of the first rotating rod 210 away from the double-head motor 207 by opening a groove. A limiting groove 215 is opened on the side wall of the groove, and the limiting groove 215 is slidably engaged with the rib 211 provided on the outer surface of the first rotating rod 210. The lead of the first lead screw 202 and the second lead screw 208 are equal.

[0034] The guide rod 203 is L-shaped, and the top end of the first lead screw 202 is rotatably connected to the guide rod 203 through a bearing. It can be understood that this setting makes the rotation of the first lead screw 202 more stable.

[0035] The bottom end of the second lead screw 208 is fixedly connected to a limiting plate 214, which prevents the second connecting plate 216 from sliding out of the second lead screw 208.

[0036] There are four ribs 211, which are arranged in a ring array along the central axis of the first rotating rod 210.

[0037] The working principle of this invention is as follows: In specific use, the dual-head motor 207 is first started. The dual-head motor 207 simultaneously drives the first rotating rod 210 and the second lead screw 208 to rotate. Then, the first rotating rod 210 drives the first lead screw 202 to rotate. Since the lead screw 202 and the second lead screw 208 have equal leads, they will synchronously drive the slider 205 and the second connecting plate 216 to move in opposite directions at equal distances. That is, the moving distance of the slider 205 and the second connecting plate 216 is adjusted simultaneously. Since the second connecting plate 216 and the pressure rod head 304 are fixedly connected, the moving distance of the slider 205 and the second connecting plate 216 is adjusted simultaneously, so that the compression amount of the spring 302 of the sliding plate 3 is adapted to the pressure of the car. The pressing force of the car key spring button does not change the travel range of the spring button driven by the pressure rod head 304. After the compression amount of the compression spring 302 is adjusted by the sliding plate 3, the car key is fixed in the positioning groove 401. By rotating the long operating handle 201, the gear 213 is rotated, thereby driving the pressure rod head 304 to move downward to press the spring button. The manual pressing force of the spring button is converted into the torque that drives the long operating handle 201 to rotate. The torque that drives the long operating handle 201 to rotate can be significantly reduced by extending the length of the long operating handle 201, making the spring button assembly time-saving and labor-saving. The assembly process is simple and easy to implement, and the assembly efficiency is high.
