Description

Technical Field

[0001] This application relates to the field of automotive testing technology, and in particular to an integrated scroll wheel button. Background Technology

[0002] With the rapid development of the automotive industry, the functions of automotive testing equipment are becoming increasingly complex. The ease of use and accuracy of its user interface directly determine the efficiency of the testing work. Currently, in practical use, operators need to press different buttons or knobs multiple times to switch functions and confirm operations. This cumbersome process affects testing efficiency, and the large number of buttons makes it easy for oil to seep into the equipment through the button openings, failing to meet the stringent requirements of the automotive testing field.

[0003] Therefore, developing an integrated roller button structure that is easy to operate and has good sealing performance for use in automotive testing equipment has become a key issue that urgently needs to be solved in the current automotive testing technology field. Utility Model Content

[0004] The purpose of this application is to overcome the shortcomings of the prior art and provide an integrated roller button structure to solve the problems of large number of buttons, cumbersome operation and poor sealing performance in traditional automobile inspection equipment.

[0005] The integrated scroll wheel button structure provided in this application adopts the following technical solution: An integrated scroll wheel button structure includes a housing, a tactile switch, a display screen, and a control module disposed on the housing and electrically connected to each other, and further includes: A roller is rotatably connected to the housing. Pressing the surface of the roller can trigger a touch switch to send a confirmation signal. The control module controls the display screen based on the confirmation signal to realize the confirmation function of the display screen. The encoder, which is installed inside the housing, is used to sense the forward and reverse rotation direction and the amount of rotation of the roller, and convert its physical rotation into an electrical signal. The control module controls the display screen based on the electrical signal to realize menu switching or parameter adjustment of the display screen. An elastic seal is provided, which fills a preset gap between the housing and the roller and surrounds the roller to cooperate with the rolling and pressing actions of the roller.

[0006] By adopting the above technical solution, the precise control of switching the display menu or adjusting parameters is achieved through the rolling and pressing of the roller, in conjunction with the encoder and the elastic seal, while ensuring efficient dust prevention and without affecting the smoothness of rolling and pressing action. This greatly simplifies the button structure and ensures its ease of operation.

[0007] Preferably, the roller includes a roller body, a rotating shaft, and a trigger. The central axis of the roller body is the same as the central axis of the rotating shaft and the central axis of the trigger. The rotating shaft passes through the roller body and is connected to the trigger. The roller body drives the trigger to press the tactile switch based on the pressing pressure. The rotating shaft is rotatably connected to the encoder and transmits the forward and reverse physical rotation signals of the roller body to the encoder.

[0008] By adopting the above technical solution, the roller body, rotating shaft, and trigger element are designed as a coaxial structure. When the roller body rolls, it maintains synchronization with the movement of the rotating shaft and trigger element. The rotating shaft passes through the roller body and is connected to the trigger element. The roller body directly transmits the pressing force to the trigger element, thereby accurately triggering the tactile switch. At the same time, the rotating shaft is rotatably connected to the encoder, transmitting the physical signals of the roller body's forward and reverse rotation completely and accurately to the encoder.

[0009] Preferably, a limiting slot is provided at one end of the rotating shaft near the encoder, and the inner wall of the rotating shaft engages with the limiting slot while the rotating shaft is rotatably connected to the rotating shaft.

[0010] By adopting the above technical solution, the existence of the limiting slot facilitates the rotation and installation between components.

[0011] Preferably, the radius of the rotating shaft built into the two ends of the roller body is larger than the radius of the middle part.

[0012] By adopting the above technical solution, the structure, which is thick at both ends and thin in the middle, makes it easy to stabilize the roller body.

[0013] Preferably, the elastic seal includes an integrally formed first sealing block and a second elastic block. The first sealing block fills a preset gap to prevent external media from entering the housing and is used to cooperate with the rolling and pressing action of the roller. The recess formed by the second elastic block and the first sealing block engages with the inner wall of the housing.

[0014] By adopting the above technical solution, the division of labor between the first sealing block and the second elastic block can not only stabilize the position of the elastic sealing element in the housing, but also effectively seal and facilitate the pressing of the roller body.

[0015] Preferably, the elastic seal is made of a soft rubber material with elastic deformation capability; the bottom of the elastic seal is provided with a protrusion for defining its own position.

[0016] By adopting the above technical solution, the soft rubber material gives the elastic seal good flexibility and resilience, which can produce adaptive deformation when the roller body rolls or is pressed. This will not hinder the movement of the roller and ensure smooth operation, but also effectively seal gaps and ensure sealing effect. At the same time, the protrusion can fit tightly against the roller fixing bracket, which can improve the stability of the elastic seal.

[0017] Preferably, a roller fixing bracket is provided inside the housing, and the roller fixing bracket has a square hole for the roller body to pass through longitudinally, the square hole communicating with the mounting hole; the roller body passes through the mounting hole and the square hole in sequence on the housing, and a portion of the roller body protrudes from the mounting hole.

[0018] By adopting the above technical solution and setting up a roller fixing bracket, a stable installation support structure can be provided for the roller body, preventing the roller from shifting position due to vibration, collision, or other factors during long-term use, and further improving the stability of rotation adjustment. At the same time, the structure with exposed mounting holes on the roller body ensures that users can easily access and operate the roller, while preventing the roller from being excessively exposed and easily damaged.

[0019] Preferably, the roller fixing bracket is provided with a limiting block, and the limiting block has a limiting hole for the trigger to pass through the limiting hole.

[0020] By adopting the above technical solution, the design of the limiting block and limiting hole can accurately limit and guide the movement trajectory of the trigger, ensuring that the trigger moves only along the axial direction during the pressing process with the roller body, avoiding radial offset or tilting of the trigger due to uneven force, thereby ensuring that the trigger can accurately and stably press the tactile switch, effectively preventing the tactile switch from being mistriggered or failing due to trigger offset, and improving the reliability of the pressing function.

[0021] In summary, this application includes at least one of the following beneficial technical effects: 1. By using the rolling and pressing of the roller, in conjunction with the encoder and elastic seals, precise control of switching the display menu or adjusting parameters is achieved while ensuring efficient dust prevention and without affecting the smoothness of the roller's rolling and pressing action. This greatly simplifies the button structure and ensures ease of operation. 2. The elastic seal is made of soft rubber with a stepped cross-section, achieving a balance between sealing performance and smooth operation. The elastic deformation capability of the soft rubber material ensures that the roller is not obstructed during rolling and pressing, guaranteeing smooth operation; the stepped structure and the raised parts work together to create an efficient dust and oil barrier, which can adapt to the complex oily environment of automotive testing equipment and reduce maintenance costs. The coordinated design of the roller fixing bracket and the limiting block provides dual stability protection for the roller and the trigger. The roller fixing bracket radially limits the roller body through a square hole, preventing the roller body from shaking during rotation; the limiting hole of the limiting block axially guides the trigger, ensuring precise pressing action. This dual-protection structure effectively improves the stability and accuracy of the integrated roller button operation, reduces operational failures caused by component misalignment, and extends the button's lifespan.

[0024] The following is in conjunction with the appendix Figure 1-6 This application will be described in further detail.

[0025] This application discloses an automobile inspection device. The commonly used surface (operating surface) of the automobile inspection device is defined as the front surface; in the orientation description of this embodiment, the front surface is used as the reference surface.

[0026] Reference Figure 1 The vehicle inspection equipment includes a housing 1, a display screen 12, and a conventional operating area 13. The display screen 12 is located on the front of the housing 1, and the conventional operating area 13 is also located on the front of the housing 1 and to the right of the display screen 12.

[0027] The surface of housing 1 is treated with a scratch-resistant and wear-resistant finish, and the contour design of housing 1 is adapted to the human hand grip posture. The display screen 12 is a high-definition touch screen used to display vehicle inspection parameters, menu options, and inspection reports. When the operator holds housing 1 with one hand, the thumb can naturally extend to the preferred operating area 13. When operating the preferred operating area 13, skilled operators can complete the operation simply by touch, without having to look down to confirm, thus improving the convenience and efficiency of operation.

[0028] Reference Figure 2 The conventional operation area 13 includes an integrated scroll wheel button 2 and a return button 3. The integrated scroll wheel button 2 is rotatably connected to the housing 1, and the return button 3 is offset to the left of the integrated scroll wheel button 2, with the upper surface of the integrated scroll wheel button 2 being higher than the upper surface of the return button 3. Through the cooperation of the integrated scroll wheel button 2 and the return button 3, device menu switching or parameter adjustment, as well as confirmation and return operations, can be quickly completed, effectively reducing hand fatigue after prolonged use.

[0029] To improve the ease of operation, reliability, and service life of the integrated roller button 2 and optimize the user experience, the integrated roller button 2 specifically includes: a roller 21 rotatably connected to the housing 1 and an encoder 22 disposed inside the housing 1.

[0030] Reference Figure 2 , 3 The roller 21 includes: an outer wall uniformly provided with anti-slip texture 7 (see reference). Figure 5 The roller body 211 comprises a roller body 211, a rotating shaft 212 passing through the roller body 211, and a trigger 213 connected to the rotating shaft 212. In this embodiment, the trigger 213 is specifically an extension of the rotating shaft 212 extending out of the center of the roller body 211, and the trigger 213 is specifically an extension block. In other embodiments, the trigger 213 may be other circular blocks or irregular block structures, and its shape is not limited here.

[0031] One end of the rotating shaft 212 near the encoder 22 has its outer wall rotatably connected to the encoder 22. To ensure stable rotation, a limiting groove is provided at the end of the rotating shaft 212 near the encoder 22 to engage with the encoder 22. This limiting groove allows the encoder 22 to rotate securely on the rotating shaft 212. To further stabilize the rolling of the roller body 211, the portion of the rotating shaft 212 built into the roller body 211 has a smaller radius at both ends than in the middle, specifically a structure that is thicker at two ends and thinner in the middle.

[0032] For ease of operation, the roller body 211 protrudes from the mounting hole 11 on the surface of the housing 1, with a protrusion height of 5-8mm. The central axis of the roller body 211 is the same as the central axis of the rotating shaft 212 and the central axis of the trigger 213.

[0033] The height of the roller body 211 protruding from the mounting hole 11 ensures that the operator can easily access the roller body 211 while avoiding the problem of easy damage caused by excessive exposure of the roller body 211. By making the central axes of the roller body 211, the rotating shaft 212 and the trigger 213 the same, the coaxiality during the movement is ensured, and the operation jamming caused by eccentricity is avoided.

[0034] In fact, in order to facilitate pressing the roller body 211, a preset gap 232 is formed between the roller body 211 and the housing 1. The preset gap 232 is 0.1-0.2mm. In order to improve the sealing performance, an elastic sealing element 23 is provided between the preset gap 232.

[0035] The elastic seal 23 is made of soft rubber material, possessing excellent elastic deformation capability and aging resistance. Its overall cross-section is stepped. Specifically, the elastic seal 23 consists of an integrally formed first sealing block and a second elastic block. The first sealing block fills the preset gap 232 to prevent external media (oil, dust) from entering the housing, thereby improving the service life of the equipment. It also indirectly cooperates with the rolling and pressing actions of the roller 21. The second elastic block forms a recess with the first sealing block, which engages with the inner wall of the housing 1 to secure the elastic seal 23 within the housing.

[0036] The bottom of the elastic seal 23 is provided with a protrusion 231, which is integrally formed with the elastic seal 23. A groove is provided inside the housing 1 to fit the protrusion 231. After the protrusion 231 is engaged in the groove, it will generate a certain compression deformation when pressed, forming an elastic clamping force to stably fix the elastic seal 23 in the installation position. At the same time, it can also prevent the elastic seal 23 from shifting due to vibration and lateral force of the roller 21 rotation during equipment operation, thereby maintaining the long-term assembly accuracy of the equipment.

[0037] In practice, the elastic seal 23 has a stepped cross-section, which can be adapted to the installation structure of various components of the automotive testing equipment, optimize the internal space, and increase the contact area between the elastic seal 23 and the housing 1. Combined with the tight contact between the elastic seal 23 and the roller fixing bracket 6, the stability of the seal can be improved.

[0038] Reference Figure 2 , 3 Inside the housing 1, there is also a tactile switch 4 located directly below the trigger 213, and a micro switch 5 located inside the housing 1 and directly below the return button 3.

[0039] Reference Figure 4To achieve electrical control of the display screen 12, micro switch 5, tactile switch 4, and encoder 22, a control module 8 is also provided inside the housing 1. This module serves as the core control unit of the equipment, responsible for outputting control signals, receiving feedback signals, and processing peripheral data. Specifically, the control module 8 can be a CPU controller, which is electrically connected to all the aforementioned devices. The control module 8 can control the display screen 12 to perform corresponding operational functions based on the activation of the micro switch 5 and tactile switch 4.

[0040] Reference Figure 3 and Figure 4 When the operator rolls the roller body 211, it drives the rotating shaft 212 to rotate. The rotation of the rotating shaft 212 drives the encoder 22 to rotate, thereby transmitting the forward and reverse physical rotation signals of the roller body 211 to the encoder 22. The encoder 22 converts the physical rotation into an electrical signal. When the control module 8 receives the corresponding electrical signal, it can realize the menu switching or parameter adjustment of the display screen 12.

[0041] When the operator presses the roller body 211, it will drive the trigger 213 to press down the tactile switch 4. After the tactile switch 4 is activated, it will output a confirmation signal to the control module 8. The control module 8 will output a confirmation signal to realize the confirmation operation.

[0042] When the return button 3 is pressed, the return button 3 triggers the micro switch 5, which sends a return electrical signal to the control module 8. This allows the control module 8 to control the display screen 12 to return to the previous menu, enabling quick reversal of the operation and further improving the operation logic.

[0043] It is worth noting that the tactile switch 4 and the micro switch 5 are symmetrically arranged on both sides of the roller body 211 along the same horizontal plane, and the two are exactly the same in shape and size, both of which are waterproof micro switches. The symmetrical arrangement makes the component layout on both sides of the roller body 211 more balanced, avoiding the shift of the device's center of gravity due to the weight difference on one side, and allowing the user to complete the operation of different buttons by applying the same force when operating the device, further optimizing the user's operating experience.

[0044] To provide positioning support for the roller body 211, a roller fixing bracket 6 is provided inside the housing 1. The roller fixing bracket 6 is fixed inside the housing 1 by screws. (Refer to...) Figure 5 The roller fixing bracket 6 has a square hole 61 that matches the cross-sectional dimensions of the roller body 211. The roller body 211 passes through the mounting hole 11 of the housing 1 and the square hole 61 in sequence. A gap of 0.2-0.3mm is reserved between the inner wall of the square hole 61 and the outer circumferential surface of the roller body 211 to ensure that the roller body 211 will not rub against the inner wall of the square hole 61 when rotating, thus ensuring smooth rotation.

[0045] To ensure that the trigger 213 moves only up and down along the axial direction and avoids radial displacement, a limit block 62 is provided on the roller fixing bracket 6, and a limit hole 63 is opened in the limit block 62 for the trigger 213 to pass through, thereby ensuring that the trigger 213 can accurately act on the center contact of the tactile switch 4 each time it is pressed, and improving the reliability of the pressing function.

[0046] The implementation principle of this embodiment is as follows: By applying an integrated roller button 2, the vehicle testing equipment greatly improves its ease of operation. It allows users to switch menus, adjust parameters, and confirm operations on the display screen 12 by rolling and pressing the roller 21, eliminating the need for cumbersome pressing of multiple physical buttons and significantly simplifying the button structure. This streamlined button structure, combined with the elastic seal 23, creates a highly efficient dust and oil barrier, adapting to the complex oily environment in which the vehicle testing equipment operates, reducing maintenance costs, and representing a significant improvement over traditional vehicle testing equipment.

[0047] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
