Description

Technical Field

[0001] This invention relates to the field of touch testing technology, and particularly to a touch testing pen and a touch testing system. Background Technology

[0002] For touchscreen terminal devices, such as smart door locks, automated testing of touch functionality, durability, and system logic is crucial for ensuring product quality. Common testing methods rely on manual point-by-point touch or complex robotic arms for simulation. Manual testing is not only inefficient, but also suffers from inconsistent touch pressure, duration, and positional accuracy, leading to poor reproducibility. This is especially problematic for durability testing requiring prolonged, repeated operations, resulting in extremely high labor costs. While robotic arms offer automation, their complex structure and high cost, coupled with the need for specialized fixtures and complex motion trajectory programming for touchscreen panels with different shapes and point layouts, result in long deployment cycles and limited versatility. Furthermore, in testing scenarios requiring coordinated operation of multiple touch points to verify system-level logic (such as password input sequences), both manual and conventional mechanical devices struggle to achieve precise and efficient parallel control. Therefore, existing touchscreen testing solutions suffer from core shortcomings: a trade-off between automation and flexibility, and difficulties in multi-point collaborative control. Summary of the Invention

[0003] The main objective of this invention is to propose a touch testing pen and a touch testing system, aiming to solve the technical problems in existing touch screen testing solutions where automation and flexibility cannot be achieved simultaneously, and multi-point collaborative control is difficult.

The controller is located inside the receiving cavity and is electrically connected to the suction cup; The controller is configured to generate touch simulation signals and transmit them to the touch screen through a conductive material to simulate preset touch operations, thereby testing the touch screen or performing logic tests on the control system of the terminal device through the touch screen.

[0005] In some embodiments, the touch test pen further includes a battery disposed in the receiving cavity and supplying power to the controller; or, the touch test pen further includes a power supply line, one end of which extends into the receiving cavity and is electrically connected to the controller, and the other end of which is adapted to obtain electrical energy and supply power to the controller.

[0006] In some embodiments, the touch test pen further includes a wireless communication module disposed in the receiving cavity. The wireless communication module is electrically connected to the controller and is adapted to wirelessly acquire test signals and transmit the test signals to the controller. The controller generates touch simulation signals based on the test signals.

[0007] In some embodiments, the entire suction cup is made of conductive material.

[0008] In some embodiments, the suction cup is detachably connected to the controller, and when the suction cup is connected to the controller, the suction cup and the housing are spaced apart; or, the suction cup is detachably connected to the controller, and when the suction cup is connected to the controller, the suction cup and the housing are connected.

[0009] In some embodiments, the suction cup is detachably connected to the controller; the housing is cylindrical and has an opening at one end, the controller is located in the receiving cavity near the opening, and the controller includes a socket portion with an elastic claw, the opening of the elastic claw being opposite to the opening; the suction cup includes an adsorption plate and a connecting protrusion, one side of the adsorption plate has an adsorption concave surface, and the other side is connected to the connecting protrusion, the connecting protrusion being adapted to extend into the receiving cavity through the opening and engage with the elastic claw and be electrically connected to the elastic claw, thereby being electrically connected to the controller.

[0010] In some embodiments, the touch test pen further includes a battery, which is disposed in a receiving cavity and powers the controller; the battery is disposed on the side of the receiving cavity opposite to the opening, and the end of the housing opposite to the opening is provided with a removable battery cover, from which the battery is removed and installed.

[0011] A second aspect of the present invention also provides a touch testing system, comprising: At least one touch test pen; and The test host is used to send test signals to the touch test pen via wired or wireless means.

[0012] In some embodiments, the touch testing system includes multiple touch test pens, and the touch screen has multiple touch points, with each touch test pen corresponding to and attached to each touch point.

[0013] In some embodiments, the touch testing system is configured to test smart door locks.

[0014] Compared with the prior art, the beneficial effects of the present invention are: In the technical solution of this invention, the touch test pen integrates the signal generation function into the controller inside the pen body, and utilizes a suction cup that is at least partially conductive to serve as both an adsorption and fixing structure and a signal transmission medium, making each test pen an independent, self-contained automated testing unit. During use, simply attach the suction cup to the target point on the touchscreen, and the built-in controller will generate and directly inject a simulated touch signal. No external signal generator or complex cables are required throughout the process, thus directly resolving the fundamental contradiction in related technologies where automation and flexibility cannot be simultaneously achieved, significantly improving the convenience and versatility of test deployment.

[0015] Furthermore, this solution utilizes suction cups for positioning, and the suction cups themselves also function as signal transmission elements, serving both a fixing and signal transmission purpose, making the installation and removal of the touch test pen extremely convenient. Additionally, multiple touch test pens can be combined to form a test array, allowing for compatibility with various terminal devices of different models, resulting in low adaptation costs.

[0019] The realization of the objective, functional features and advantages of the present invention will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation

[0020] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0021] Touchscreen testing pens are used for factory testing of touchscreen-equipped devices such as smart locks, smart switches, and tablets. The touchscreen is the core interface for user interaction in these devices, and its sensitivity, response consistency, and long-term durability directly impact the user experience and product reputation. In related technologies, testers typically use manual methods, holding a conductive stylus or directly tapping the touchscreen points one by one according to a preset sequence. Taking smart lock password input testing as an example, testers need to repeatedly enter six to eight digit passwords. Manual operation can only complete a few hundred tests per day, and the pressure and duration of each tap vary significantly, resulting in poor reproducibility of test results, especially in durability testing where labor costs are extremely high.

[0022] Automated testing solutions using general-purpose multi-axis robotic arms to hold conductive contacts have emerged in related technologies. This solution controls the robotic arm's movement trajectory through programming, allowing the conductive contacts to touch the touchscreen along a preset path. However, the robotic arm itself has a complex structure, with a single unit costing hundreds of thousands of yuan. Furthermore, spatial coordinates need to be recalibrated and motion programs rewritten for touchscreens with different layouts, resulting in a deployment cycle of 3 to 7 days for a single device, making it difficult to quickly adapt to product updates and iterations. In recent years, suction cup touchscreen devices have also appeared in the industry, using conductive suction cups to attach contacts to touchscreen points, and then connecting to an external signal generator via external cables. However, this solution requires an independent cable for each contact, leading to dense cable crisscrossing during multi-point testing, and the external signal generator is bulky and difficult to deploy flexibly at different testing stations.

[0023] In view of this, see Figures 1 to 2 This embodiment provides a touch test pen 100 and a touch test system including the touch test pen 100. The touch test pen 100 includes a housing 110, a suction cup 120 and a controller 130.

[0024] The housing 110 defines a receiving cavity 111, and the housing 110 has an opening 112 communicating with the receiving cavity 111. The housing 110 provides structural support and protective space for the internal components of the touch test pen 100. Its overall shape can be elongated, cylindrical, or prismatic. In this embodiment, a cylindrical shape is preferred to facilitate handheld deployment and point adjustment by the operator. The material of the housing 110 can be engineering plastic, aluminum alloy, or carbon fiber composite material. Engineering plastic has the advantages of low cost and good insulation, aluminum alloy has the characteristics of good heat dissipation and high structural strength, and carbon fiber composite material has the characteristics of both lightweight and high strength. The choice can be made according to the actual application scenario. The opening 112 provides a channel for the suction cup 120 to extend into the receiving cavity 111. Its shape is adapted to the connection part of the suction cup 120 to ensure that the suction cup 120 can be smoothly inserted and connected to the internal components.

[0025] Based on the housing 110, the suction cup 120 is at least partially made of conductive material. One end of the suction cup 120 is connected to the housing 110 and extends into the receiving cavity 111 through the opening 112. The other end of the suction cup 120 is adapted to be attached to the touchscreen of the terminal device. The suction cup 120 has the dual functions of physical adsorption and fixation and electrical signal conduction. Its adsorption function is achieved by pressing out the air in the adsorption concave surface 123, using atmospheric pressure to fix the touch test pen 100 to the touchscreen surface, without the need for additional clamping or support structures. Its signal conduction function is achieved by transmitting the touch analog signal generated by the controller 130 to the touchscreen through the internal conductive path. The conductive material can be of various types. For example, it can be conductive silicone, conductive rubber, or an elastic material with a copper or silver conductive layer coated on the surface. In this embodiment, conductive silicone is preferred as the conductive material, which has good elasticity, sealing performance, and conductivity, and can achieve low-impedance signal transmission while ensuring strong adsorption.

[0026] The controller 130 is disposed within the receiving cavity 111 and electrically connected to the suction cup 120 through the cooperation of the housing 110 and the suction cup 120. The controller 130 is configured to generate touch simulation signals and transmit these signals to the touchscreen via a conductive material to simulate preset touch operations, thereby testing the touchscreen or performing logic tests on the control system of the terminal device through the touchscreen. The controller 130 is the functional core of the touch test pen 100, and it integrates a signal generation circuit that can independently generate electrical signals conforming to the touchscreen sensing principle. For the widely used capacitive touchscreens, the controller 130 generates touch simulation signals by changing the potential state of the conductor in contact with the touchscreen, causing a change in the capacitance value at that point on the touchscreen surface. The touchscreen controller detects this change and determines it as a touch event. The controller 130 can simulate touch operations including short presses, long presses, continuous presses, and multi-touch simultaneously. The duration of a short press ranges from 50 milliseconds to 500 milliseconds, and can be, for example, 50 milliseconds, 100 milliseconds, 200 milliseconds, 300 milliseconds, and 500 milliseconds. The duration of a long press ranges from 2 seconds to 10 seconds, and can be, for example, 2 seconds, 5 seconds, and 10 seconds. By adjusting the duration, interval, and repetition count of the output signal, the controller 130 can accurately simulate different user touch behaviors.

[0027] In summary, in this solution, the housing 110 provides integrated storage space for internal components, the suction cup 120 simultaneously performs the dual functions of physical adsorption and electrical signal conduction, and the controller 130 integrates signal generation within the pen body, making each touch test pen 100 an independent, self-contained automated testing unit. During use, simply attach the suction cup 120 to the target touchscreen location, and the built-in controller 130 will generate and directly inject a simulated touch signal, eliminating the need for external signal generators and complex cables. Compared to the inefficient and inconsistent manual testing methods in related technologies, this solution significantly improves testing efficiency, and the duration and intensity errors of each touch can be controlled within a low range. Compared to the long deployment cycle and poor versatility of robotic arm solutions in related technologies, the deployment time of this solution can be shortened to less than 10 minutes, greatly reducing the test preparation cycle and enabling rapid adaptation to touchscreen products with different layouts and shapes. Compared to the suction cup devices in related technologies that require external signal generators and dense cables, this solution eliminates the constraints of external cables, preventing cable tangling during multi-point testing, and making deployment and maintenance more convenient.

[0028] The touch test pen 100 also includes a battery 140, which is housed in the receiving cavity 111 and supplies power to the controller 130. The battery 140, located within the receiving cavity 111, has its output terminal electrically connected to the power input terminal of the controller 130. The battery 140 can be a disposable battery or a rechargeable battery. Disposable batteries, such as button batteries or alkaline dry batteries, offer the advantages of easy replacement and no need for charging. Rechargeable batteries, such as lithium polymer batteries or lithium-ion batteries, feature large capacity, recyclability, and lower long-term operating costs. In this embodiment, the battery 140 is preferably a rechargeable 14500-specification lithium-ion battery with a capacity of up to 800mAh, capable of supporting continuous operation of the touch test pen 100 for more than 72 hours. In this solution, because the battery 140 provides independent power, the touch test pen 100 requires no external cable connection during operation and can be freely deployed at any test point, offering extremely flexible and convenient deployment, particularly suitable for testing scenarios with many test points and limited space.

[0029] The touch test pen 100 also includes a power supply cable 150. One end of the power supply cable 150 extends into the receiving cavity 111 and is electrically connected to the controller 130, while the other end is adapted to obtain electrical energy and supply power to the controller 130. One end of the power supply cable 150 extends into the receiving cavity 111 through a wire hole opened on the housing 110 and is electrically connected to the power input terminal of the controller 130. The other end of the power supply cable 150 is located outside the housing 110 and is used to connect to an external power adapter, mobile power supply, or the DC power supply bus of the test station. The length of the power supply cable 150 can be set according to actual needs, generally from 1 meter to 5 meters, for example, it can be 1 meter, 2 meters, 3 meters, or 5 meters. In this solution, because it uses an external power supply for continuous power supply, the touch test pen 100 is not limited by battery capacity and can operate continuously for 24 hours, making it suitable for durability testing or large-volume continuous testing scenarios that require long-term continuous operation.

[0030] In a preferred embodiment, the touch test pen 100 can integrate both a battery 140 and a power supply cable 150, and is equipped with a power switching switch. When the power supply cable 150 is connected, it automatically switches to external power supply and simultaneously charges the battery 140; when the power supply cable 150 is disconnected, it automatically switches to battery power supply. This solution combines the advantages of both power supply methods, meeting the needs of long-term continuous testing while also functioning normally during power outages or when relocation is required.

[0031] The touch test pen 100 also includes a wireless communication module 160 disposed in the receiving cavity 111. The wireless communication module 160 is electrically connected to the controller 130. The wireless communication module 160 is adapted to wirelessly acquire test signals and transmit the test signals to the controller 130. The controller 130 generates touch simulation signals based on the test signals. The specific communication protocol of the wireless communication module 160 can be various, for example, Bluetooth, Wi-Fi, ZigBee, LoRa, etc. Bluetooth protocol has the advantages of low power consumption and fast connection speed, suitable for short-range, low-latency control scenarios; Wi-Fi protocol has the characteristics of high transmission rate and wide coverage, suitable for scenarios requiring the transmission of large amounts of data; ZigBee protocol has the advantages of strong networking capability and extremely low power consumption, suitable for large-scale, multi-point testing scenarios. In this embodiment, the wireless communication module 160 preferably integrates a patch module with Bluetooth 4.2 protocol, which has a transmission distance of up to 10 meters, meeting the needs of most testing scenarios, and its power consumption is only 5mA, which will not significantly affect the battery life of the battery 140. In this solution, the addition of a wireless communication module 160 upgrades the touch test pen 100 from a previously independent and self-consistent signal generator into a remotely controllable test execution terminal. This allows the remote control center to flexibly control the working sequence and mode of each touch test pen 100, providing a component-level technical prerequisite for building a multi-point testing system. Compared to related technologies that require cable transmission of control signals, this solution eliminates the constraints of control cables, further enhancing deployment flexibility and convenience.

[0032] The suction cup 120 is entirely made of conductive material. The entire suction cup 120 is integrally molded from the same conductive material; that is, from the outer adsorption working surface to the connecting end extending into the receiving cavity 111, the entire substrate is conductive. In this embodiment, the suction cup 120 is integrally molded from conductive silicone, with carbon conductive particles uniformly dispersed within the silicone substrate. The mass fraction of the carbon powder is 15% to 30%, exemplarily 15%, 20%, 25%, or 30%. When the carbon powder mass fraction is within this range, the conductive silicone maintains good elasticity and sealing performance while achieving a low volume resistivity, typically less than 10 Ω·cm, meeting the requirements for signal transmission. In this solution, because the suction cup 120 is integrally molded from conductive material, the signal does not need to cross any heterogeneous interfaces within the suction cup 120, fundamentally eliminating the risk of internal contact resistance and interface peeling, thus improving the long-term operational reliability and signal transmission efficiency of the suction cup 120. Compared to related technologies that use an insulating substrate with a conductive coating on the surface for the suction cup, this solution avoids the problem of wear and peeling of the conductive coating, effectively improving the service life of the suction cup.

[0033] The suction cup 120 is detachably connected to the controller 130, and when connected, the suction cup 120 is spaced apart from the housing 110. That is, the suction cup 120 extends into the opening 112 and maintains its position through its connection with the controller 130. A gap of 0.5 mm to 2 mm exists between the peripheral wall of the suction cup 120 and the inner wall of the opening 112, with no direct contact between them. In this design, due to the gap between the suction cup 120 and the housing 110, the suction cup 120 can undergo slight elastic deformation during adsorption, better conforming to the touchscreen surface and improving the adhesion. Simultaneously, the gap also prevents the housing 110 from contacting the touchscreen surface, thus preventing the housing 110 from scratching the touchscreen.

[0034] The suction cup 120 is detachably connected to the controller 130, and when connected to the controller 130, the suction cup 120 is also connected to the housing 110. That is, after the suction cup 120 extends into the opening 112, its outer wall and the inner wall of the opening 112 form a mating relationship, which can be an interference fit, a snap-fit ​​connection, or a threaded connection. The housing 110 provides additional radial support to the suction cup 120 through the opening 112, making the suction cup 120 more securely fixed. This solution is suitable for testing scenarios that require withstanding significant external forces or vibrations, effectively preventing the suction cup 120 from loosening or falling off during testing. In this solution, because the suction cup 120 and the controller 130 are detachably connected, when the suction cup 120 wears or deforms due to long-term use, or when it needs to be replaced with a suction cup of different size and hardness to adapt to different touchscreens, the operator can easily replace it on-site without disassembling the entire touch test pen 100, significantly reducing maintenance costs and the operational threshold. Compared to the solution of fixing the suction cup to the pen body in related technologies, the maintenance cost of this solution can be reduced by more than 60%, and it can be quickly adapted to different testing needs.

[0035] The suction cup 120 is detachably connected to the controller 130. The housing 110 is cylindrical with an opening 112 at one end. The controller 130 is located in the receiving cavity 111 near the opening 112. The controller 130 includes a socket 131 with a resilient claw. The opening of the resilient claw is opposite to the opening 112. The suction cup 120 includes an adsorption plate 121 and a connecting protrusion 122. One side of the adsorption plate 121 has an adsorption concave surface 123, and the other side is connected to the connecting protrusion 122. The connecting protrusion 122 is adapted to extend into the receiving cavity 111 through the opening 112 and engage with the resilient claw, thereby electrically connecting to the controller 130. The housing 110 is cylindrical in shape, with an outer diameter of 15 mm to 25 mm and a length of 100 mm to 150 mm. For example, it can have an outer diameter of 18 mm and a length of 120 mm. The controller 130 is a 15mm x 15mm PCB board soldered to the front end of the receiving cavity 111 near the opening 112. The insertion port 131 is soldered to the front end face of the controller 130 and includes at least one pair of resilient claws. These claws are formed by stamping and bending a phosphor bronze sheet with a thickness of 0.2mm to 0.5mm. The phosphor bronze sheet has good elasticity and conductivity, maintaining stable clamping force and contact resistance even after long-term insertion and removal. The width of the opening of the resilient claw is slightly smaller than the thickness of the connecting protrusion 122 to ensure clamping force. The suction cup 120 has a suction cup 121 with a diameter of 10mm to 20mm, a bowl-shaped structure, and a suction concave surface 123 with a depth of 2mm to 5mm, providing sufficient suction force, typically capable of withstanding a pulling force of 5N to 10N. The connecting protrusion 122 is a flat rectangular protrusion extending rearward from the center of the back of the suction cup 121. It has a thickness of 1 mm to 3 mm and a length of 5 mm to 10 mm, with a smooth surface for easy insertion of the elastic claw. During connection, the connecting protrusion 122 is aligned with the opening 112 and inserted inward. The elastic claw expands elastically under the pressure of the connecting protrusion 122. Once the connecting protrusion 122 is fully inserted, the elastic claw recovers its elasticity and clamps the connecting protrusion 122, simultaneously achieving physical fixation and electrical connection. For disassembly, simply hold the suction cup 121 and pull it outward to overcome the clamping force of the elastic claw to remove the suction cup 120. In this design, because a flexible snap-fit ​​mechanism is used to achieve a detachable connection, the entire assembly and disassembly process requires only one insertion or pulling action, making operation extremely convenient and reducing assembly and disassembly time to less than 1 second. Simultaneously, the large area of ​​elastic contact provided by the elastic claw ensures the reliability of the electrical connection, with contact resistance consistently below 0.1Ω, preventing poor contact due to vibration or minor displacement. Compared to the threaded connection method used in related technologies, this solution improves the disassembly and assembly efficiency by more than 10 times, and avoids problems such as thread stripping and poor contact.

[0036] The touch test pen 100 also includes a battery 140, which is located in the receiving cavity 111 and supplies power to the controller 130. The battery 140 is located on the side of the receiving cavity 111 opposite to the opening 112, and a detachable battery cover 113 is provided at the end of the housing 110 away from the opening 112. The battery 140 is removed and installed from the battery cover 113. The battery 140 is located at the rear end of the receiving cavity 111, i.e., on the side away from the opening 112, forming a front-rear partition with the controller 130 and suction cup 120 at the front end. The battery cover 113 is installed at the rear end of the housing 110 by threaded connection or snap-fit ​​connection. In this embodiment, threaded connection is preferred, with a thread pitch of 1 mm, requiring only two rotations for installation or removal. The outer surface of the battery cover 113 has anti-slip textures for easy screwing. In this design, because the battery 140 adopts a tail-end layout and has an independent battery cover 113, when the battery 140 is depleted and needs to be replaced, the operator only needs to unscrew the battery cover 113 at the tail end to remove the battery 140. There is no need to disassemble the front-end suction cup 120 or the controller 130, and the operation will not interrupt the already deployed suction cup's adsorption state. Compared to related technologies where the battery is integrated with the front-end components, this design makes battery replacement more convenient and does not affect the continuity of testing.

[0037] This embodiment also provides a touch testing system, which includes at least one touch test pen as described in any of the above embodiments; and a test host for sending test signals to the touch test pen via wired or wireless means. The touch testing system adopts a distributed architecture with centralized control and decentralized execution. The test host is the control core of the system, and the touch test pen is the distributed execution terminal. The hardware structure of the test host includes a processing unit, a storage unit, and a communication interface. The processing unit can be an industrial-grade microprocessor or an embedded processor. The storage unit is used to store test scripts and test data. The communication interface can include a USB interface, an Ethernet interface, a Bluetooth module, a Wi-Fi module, etc., depending on the communication method. In this embodiment, the test host is preferably an industrial-grade tablet computer pre-installed with test control software, with a screen size of 10 inches, facilitating operator setting of test parameters and viewing of results. The test host establishes a wireless connection with the touch test pen via Bluetooth, and can connect more than 32 touch test pens simultaneously, meeting the needs of most multi-point tests. In this solution, due to the distributed architecture, the test host acts as the command center. Users can preset test scripts, arrange test task sequences, and generate test instructions on the test host, which are then uniformly sent to each touch test pen for execution. Compared to related technologies where each test unit works independently, this system can achieve multi-point collaborative control, remote management, and automated integration, and can execute complex logic test tasks that require sequential combination of multiple touch operations.

[0038] The touch testing system includes multiple touch test pens. The touchscreen has multiple touch points, and each touch test pen is attached to one of these touch points. The number of touch test pens in the system corresponds one-to-one with the number of touch points to be tested on the touchscreen. Each touch test pen is independently attached to its corresponding touch point, forming a modular, fixed deployment with one pen per point. Taking a smart door lock with twelve touch points as an example, its touchscreen has ten numeric keys (0-9) and two function keys (such as "Confirm" and "Cancel"). In actual deployment, the suction cups 120 of the twelve touch test pens are pressed and attached to the surfaces of these twelve touch points. The housings 110 of the touch test pens are independent of each other and do not interfere with each other mechanically. After deployment, no pen needs to be moved during the entire testing cycle. During testing, the testing host only needs to send commands to the corresponding touch test pens according to the preset timing sequence to complete the entire testing sequence. This solution employs a fixed, one-to-one deployment of multiple pens, pre-positioning the test execution units for all touch points physically, thus completely eliminating the need for motion path planning during testing. For a touchscreen with N points, a single-pen solution requires N sequential processes of adsorption-testing-removal, while this solution only requires one parallel deployment of all pens. All subsequent test steps can be completed through pure software commands. This multi-point parallel deployment significantly improves the efficiency of multi-touch testing. Furthermore, when changing the test product model, simply remove all touch test pens and re-adsorb them according to the new touchscreen's layout. The control-side test program only needs to adjust the correspondence between the target pen and the point, without changing any hardware or motion control program, making it highly versatile.

[0039] The touchscreen testing system is configured for testing smart door locks. Smart door lock touchscreens are typically mounted vertically on the door panel or lock body panel, and their integrated touch points have clearly defined logical functions, such as numeric input, confirmation, and cancellation. The touchscreen testing system utilizes the vacuum adsorption capability of its suction cups (120mm), allowing it to firmly adhere to the vertical touchscreen surface with an adsorption force exceeding 5N, enabling it to withstand vibrations and external forces during testing without detaching. Furthermore, the touchscreen testing system's multi-point collaborative logic testing capabilities, especially its simulation of serialized password input operations, precisely cover the core functional testing requirements of smart door locks before they leave the factory, including password input correctness testing, incorrect password locking testing, combination key function testing, and touch durability testing. This solution, by specifically configuring the touchscreen testing system for smart door lock testing, fully leverages its advantages of reliable adsorption and fixation, precise multi-point collaboration, and flexible and convenient deployment, significantly improving the testing efficiency and quality of smart door locks. Compared to dedicated testing equipment for smart locks in related technologies, this system can quickly adapt to smart lock products of different brands and layouts without the need for customized fixtures, thus reducing equipment investment costs.

[0040] The following provides a complete implementation scheme for a touch testing system integrating all core optimization features. The touch testing system includes a testing host and twelve touch test pens. The specific structure of each touch test pen is as follows: The housing 110 is an elongated cylindrical shape, made of ABS engineering plastic, 120 mm long and 18 mm in outer diameter. A receiving cavity 111 is defined inside the housing 110. An opening 112 is provided at the front end of the housing 110, communicating with the receiving cavity 111. A removable battery cover 113 is provided at the rear end of the housing 110, screwed onto the rear end of the housing 110, and has anti-slip textures on its outer surface. The suction cup 120 is integrally molded from conductive silicone, with a carbon powder mass fraction of 20% and a volume resistivity of 5 Ω·cm. The suction cup 120 includes an adsorption plate 121 at the front end and a connecting protrusion 122 at the rear end. The adsorption plate 121 has a diameter of 15 mm and a bowl-shaped adsorption concave surface 123 on its front side, with a depth of 3 mm. The connecting protrusion 122 is a flat, rectangular conductive silicone bump extending rearward from the center of the suction cup 121, with a thickness of 2 mm and a length of 8 mm. The controller 130 is located in the front end area of ​​the receiving cavity 111 near the opening 112. It is a PCB board integrating an ARM Cortex-M0 microprocessor and capacitor analog circuitry, with dimensions of 15 mm × 15 mm. A socket portion 131 is soldered to the front end of the controller 130. The socket portion 131 consists of a pair of elastic claws, which are formed by stamping and bending 0.3 mm thick phosphor bronze sheets, with their openings facing the opening 112. In the assembled state, the connecting protrusion 122 extends into the receiving cavity 111 through the opening 112, directly inserts into the openings of the elastic claws, and is elastically clamped and locked in place. The suction cup 120 achieves both a stable physical connection and a low-impedance electrical connection with the controller 130 through this elastic locking mechanism, and a 1 mm gap is provided between the suction cup 120 and the inner wall of the opening 112 of the housing 110. A rechargeable 14500 lithium-ion battery 140 with a capacity of 800mAh is installed at the rear end of the receiving cavity 111. The output terminal of the battery 140 is soldered to the power input terminal of the controller 130 via wires. The battery 140 can be easily removed for charging or replacement after unscrewing the battery cover 113, without touching the suction cup 120 or the controller 130 at the front end. A wireless communication module 160 is installed in the middle of the receiving cavity 111. The wireless communication module 160 uses a surface-mount module with integrated Bluetooth 4.2 protocol, and its data communication pins are soldered to the serial communication interface of the controller 130. The wireless communication module 160 is used to receive wireless test signals from the test host and transmit the parsed command data to the controller 130. The test host is a 10-inch industrial-grade tablet computer pre-installed with test control software and has a built-in Bluetooth 5.0 communication module. The test host pairs with the wireless communication modules 160 of twelve touch test pens via Bluetooth and establishes a wireless data connection.In the deployed state, the twelve touch test pens are attached one-to-one with the ten numeric keys (0-9) and two function keys ("Confirm" and "Cancel") on the smart door lock touchscreen via their respective suction cups 120. Each touch test pen constitutes an independent touch signal injection terminal.

[0041] As a variant embodiment, when the test scenario requires long-term uninterrupted operation for durability testing, the battery 140 and wireless communication module 160 in the above embodiment can be omitted and replaced with a power supply line 150. One end of the power supply line 150 extends from the wire hole at the tail end of the housing 110 into the receiving cavity 111 and is soldered to the controller 130; the other end is connected to an external 5V DC regulated power supply. The test host can be directly connected to the controller 130 of each touch test pen via a USB cable for wired command transmission and continuous power supply. This solution removes the limitation of battery life and can meet the durability testing requirements of hundreds of thousands of continuous clicks.

[0042] The complete workflow of this solution is as follows: In the initial state, the testers first completed the system deployment. They aligned the suction cups 120 of the twelve touch test pens with the suction recesses 123 of the pens, one by one, on the twelve touch points of the smart lock touchscreen, pressing firmly to expel air and securely attach the suction cups 120 to the touchscreen surface. At this time, the connecting protrusions 122 of each touch test pen were pre-engaged in the elastic claws of its respective controller 130, completing the electrical and structural connection. The batteries 140 of each touch test pen were installed and powered on, while the controller 130 and the wireless communication module 160 were in standby mode, with a standby current of less than 1mA. The test host was powered on and the test control software was run. Under normal testing conditions (within 10 meters, unobstructed, and free from strong electromagnetic interference), the system searched for and established wireless connections with the twelve touch test pens via Bluetooth, achieving a 100% connection success rate under these conditions. The system was then ready.

[0043] Testers set up a test task through the test host's software interface: simulating the input of a correct six-digit password "1-2-3-4-5-6" and pressing the "Confirm" button, repeating the test 100 times with a 1-second interval between each test. The test host's processing unit parses this test task into a series of test signal queues with timing and object identifiers. Each signal contains the address of the target touch pen, the touch type (short press), and the touch duration (milliseconds).

[0044] After the test begins, the test host sends a test signal via Bluetooth to the touch test pen attached to point "1" according to a preset timing sequence. Upon receiving the test signal, the touch test pen's wireless communication module 160 transmits the command to the controller 130. The controller 130 generates a sequence of capacitive analog signals corresponding to a millisecond short press operation and transmits the signal to the suction cup 121 via a connecting protrusion 122 elastically connected to its socket 131. The signal is injected into point "1" of the touchscreen via the suction concave surface 123. The smart door lock touchscreen controller detects this touch event and records it as the input of the number "1". Subsequently, the test host sends signals sequentially to the touch test pens at points "2", "3", "4", "5", "6", and "Confirm" in the same manner, with a transmission interval of 300 milliseconds for each signal. Each touch test pen executes the command independently, generating its own touch analog signal. During this process, the elastic snap-fit ​​mechanism ensures the electrical connection reliability of each signal transmission. The deployment of multiple pens allows the test host to complete the input of the entire password sequence simply by command, without any mechanical movement.

[0045] After the final "confirm" key signal is injected, the smart lock's control system receives the complete password sequence and executes the unlocking logic. If the lock is a qualified product, its motor should activate and unlock, sending an unlock status signal back to the test host via the debugging interface. The test host records the result of this test as "pass" and stores the test time and response duration. If the lock does not respond or responds incorrectly, the test host records the result of this test as "failure" and marks the reason for the failure. Subsequently, the system waits for 1 second and then loops into the next test until the preset 100 repetitions are completed.

[0046] When testing the locking logic of a smart lock after consecutive incorrect password entries, the tester only needs to adjust the test sequence in the test host software, changing the last digit of the password to an incorrect number and setting the consecutive error count to 5. The test host will then send instructions according to the new test sequence to verify whether the lock triggers an alarm or temporarily locks after 5 consecutive incorrect entries. Throughout the entire testing process, the tester does not need to touch any touch-sensitive test pen, achieving fully automated remote unattended testing.

[0047] Throughout the entire process, the controller 130 monitors the voltage of the battery 140 in real time. When the voltage of the battery 140 is detected to be lower than 3.2V, the controller 130 sends a low battery alarm signal to the test host via the wireless communication module 160. The test host then displays a prompt window to remind the test personnel to replace the battery in time.

[0048] It should be noted that if directional indications (such as up, down, left, right, front, back, etc.) are involved in the embodiments of the present invention, these directional indications are only used to explain the relative positional relationships and movement of the components in a specific posture. If the specific posture changes, the directional indications will also change accordingly. When a direction reference is introduced in a specific embodiment, unless the direction is specifically limited to unidirectional, the direction can be unidirectional or bidirectional (two parallel and opposite directions). Whether it is unidirectional or bidirectional depends on what those skilled in the art can achieve. When the direction reference is bidirectional, it should be considered that two parallel and different embodiments have been introduced simultaneously.

[0049] Furthermore, if the embodiments of this invention involve descriptions such as "first" or "second," these descriptions are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of those features. Additionally, the use of "and / or," "and / or," or "and / or" throughout the text implies three parallel solutions. For example, "A and / or B" includes solution A, solution B, or a solution where both A and B are satisfied simultaneously. Furthermore, the technical solutions of the various embodiments can be combined with each other, but this must be based on the ability of those skilled in the art to implement them. When the combination of technical solutions is contradictory or impossible to implement, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection claimed by this invention.
