Description

Technical Field

[0001] This invention relates to the field of automotive parts, and more specifically, to a car-mounted beverage dispenser and its anti-shake locking structure, a car-mounted armrest box, and a vehicle. Background Technology

[0002] With the upgrading of consumption in the automotive aftermarket, drivers and passengers are increasingly demanding more comfort and convenience in their in-car lives, and in-car devices with the function of making drinks on demand are gradually becoming a new consumer hotspot.

[0003] Currently, in-vehicle beverage dispensers on the market are mainly divided into two categories: one is a portable, standalone product that is placed directly on the armrest box, cup holder, or seat surface without any fixed structure; the other uses simple structures such as clips and Velcro for temporary fixation.

[0004] The above technical solution has the following drawbacks:

[0005] Portable beverage machines are prone to significant horizontal swaying when encountering bumpy roads, emergency braking, or sharp turns while the vehicle is in motion, which can lead to spilled beverages, damage to the equipment, or even safety threats to drivers and passengers due to the equipment sliding or flying off. Simple fixing structures suffer from poor adaptability and insufficient locking strength, failing to meet the fixing requirements of beverage machines and other devices with a certain weight and piping structure.

[0006] In addition, if additional mounting holes are temporarily added to the portable beverage machine, these holes will be directly exposed after the machine is removed, making them prone to accumulating dust and debris. This will not only affect the cleanliness of the interior but also negatively impact the accuracy and stability of subsequent reinstallation.

[0007] Therefore, there is an urgent need for a vehicle-mounted equipment fixing structure that can achieve deep integration of the vehicle-mounted beverage machine and the armrest box, take into account both horizontal anti-sway and vertical locking, and also have dustproof function. Summary of the Invention

[0008] The purpose of this invention is to provide a vehicle-mounted beverage machine and its anti-shake locking structure, vehicle armrest box and vehicle, so as to alleviate the technical problems of existing vehicle-mounted beverage machines lacking a dedicated fixing structure, being prone to shaking and having dust easily accumulating in the mounting holes.

[0009] This invention provides an anti-shake locking structure for a vehicle-mounted beverage machine. The anti-shake locking structure includes a vehicle armrest box body and a beverage machine body. The vehicle armrest box body has a receiving cavity, and at least two insertion holes are opened at the bottom of the receiving cavity. The bottom of the beverage machine body is provided with insertion posts adapted to the insertion holes. An elastic dustproof skirt is fixed to the inner wall edge of the insertion hole. The elastic dustproof skirt closes the opening of the insertion hole in its natural state. When each of the insertion posts is inserted into the insertion hole, the elastic dustproof skirt undergoes elastic deformation and adheres tightly to the outer wall of the insertion post, forming a horizontal limiting constraint. The anti-shake locking structure also includes an electromagnetic lock device, which includes an electromagnetic lock body installed at the bottom of the accommodating cavity and an electromagnetic lock attraction block installed at a corresponding position on the bottom of the beverage machine body. When the electromagnetic lock body is energized, it generates a magnetic force to attract the electromagnetic lock attraction block, thereby achieving vertical locking of the beverage machine body.

[0010] In some embodiments, there are four insertion holes arranged in a rectangular array at the bottom of the accommodating cavity, and the insertion posts are four cylindrical pillars that correspond one-to-one with the insertion holes.

[0011] In some embodiments, the elastic dustproof skirt is composed of several isosceles triangular elastic rubber sheets, the bottom edge of the elastic rubber sheet is fixedly connected to the inner wall of the insertion hole, the hypotenuse faces the central axis of the insertion hole, and the ends of each elastic rubber sheet are in contact with each other in the horizontal plane in a natural state.

[0012] In some embodiments, the electromagnetic lock body is electrically connected to the vehicle's central control system, and the driver and passengers output on / off signals to the central control system through preset control buttons inside the vehicle to control the power supply and de-energization of the electromagnetic lock body.

[0013] In some embodiments, the anti-shake locking structure of the vehicle-mounted beverage machine further includes a contact-type limit switch and a first prompting sound device; the contact-type limit switch is located at the bottom of the accommodating cavity or the bottom of the beverage machine body, and the contact-type limit switch is electrically connected to the electromagnetic lock device and the first prompting sound device; when the plug is fully inserted into the plug hole and the electromagnetic lock device is energized and engaged, the contact-type limit switch is triggered, and the first prompting sound device emits an installation confirmation sound according to the trigger signal.

[0014] In some embodiments, the anti-shake locking structure of the vehicle-mounted beverage machine also includes a locking status sensor and a second prompting sound device; The locking status sensor is disposed on the electromagnetic lock body or the electromagnetic lock attraction block, and is used to detect the actual adsorption distance between the electromagnetic lock body and the electromagnetic lock attraction block; The second prompting sound device is electrically connected to the locking status sensor and the electromagnetic lock device; When the electromagnetic lock device is powered on and the locking status sensor detects that the adsorption distance is less than or equal to a preset threshold, the second prompting sound device emits a locking success prompt sound. When the electromagnetic lock device is powered on but the locking status sensor does not detect an adsorption gap less than or equal to a preset threshold within a preset time, the second prompting sound device emits a locking failure alarm sound.

[0015] In some embodiments, the elastic dustproof skirt is made of elastic rubber and is fixedly connected to the edge of the insertion hole by adhesive bonding or insert injection molding.

[0016] In some embodiments, the electromagnetic lock device is powered by 12V or 24V DC, and its power supply line is adapted to the vehicle power system.

[0017] In some embodiments, the plug and the plug hole are clearance-fitted.

[0018] The present invention also provides a vehicle armrest box, which includes the anti-shake locking structure of the above-mentioned vehicle beverage machine.

[0019] The present invention also provides a vehicle-mounted beverage machine, which includes a beverage machine body and at least two plug-in pins and an electromagnetic lock engaging block disposed at the bottom of the beverage machine body; the plug-in pins are configured to be plugged into the plug-in holes at the bottom of the vehicle armrest box accommodating cavity to achieve horizontal limiting; the electromagnetic lock engaging block is configured to be magnetically engaged with the electromagnetic lock body at the bottom of the accommodating cavity to achieve vertical locking.

[0020] The present invention also provides a vehicle that includes the above-described vehicle armrest box.

[0021] The beneficial effects of this invention are: The present invention relates to a vehicle-mounted beverage dispenser, its anti-shake locking structure, a vehicle-mounted armrest box, and a vehicle. By opening a connector hole at the bottom of the armrest box's accommodating cavity and correspondingly setting a connector post at the bottom of the beverage dispenser, and providing an elastic dustproof skirt along the inner edge of the connector hole, the dispenser naturally closes the opening. During installation, it deforms under pressure and adheres tightly to the outer wall of the connector post, forming a horizontal limiting constraint. Simultaneously, an electromagnetic lock device is used, with a lock body and a suction block respectively located at the bottom of the accommodating cavity and the bottom of the beverage dispenser body. Upon energization, magnetic attraction is generated to achieve vertical locking, thus achieving dual horizontal and vertical fixation. This effectively prevents the beverage dispenser from shaking, spilling, or even flying out due to bumps during vehicle operation, improving driving safety. The elastic dustproof skirt automatically closes the connector hole when not in use, preventing dust and debris accumulation, maintaining interior cleanliness and installation accuracy. Furthermore, the armrest box can be restored to independent storage function after the beverage dispenser is removed, combining practicality, convenience, and multi-functional utilization of vehicle interior space.

Detailed Implementation

[0024] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, 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 some, not all, of the embodiments of the present invention. The components of the embodiments of this application described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0025] In the description of this invention, it should be noted that the terms "inner," "outer," "upper," "lower," "left," and "right," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship commonly used when the product of this application is in use. They are only used for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on this application. In addition, the terms "first," "second," etc., are only used to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0026] In the description of this invention, it should also be noted that, unless otherwise explicitly specified and limited, the terms "set" and "connection" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0027] This invention aims to solve the problems of shaking, abnormal noise, and even tipping of vehicle-mounted beverage machines caused by vehicle bumps, acceleration, deceleration, and turning during operation. In existing technologies, beverage machines mostly adopt simple placement or one-way locking structures, which can only apply pressure in one direction for fixation and cannot effectively restrain horizontal displacement. This leads to repeated collisions between the beverage machine and the inner wall of the receiving cavity, generating noise, and even causing the connection structure to loosen and fail due to long-term impact. At the same time, the insertion holes are easily exposed and accumulate dust and liquid residue, affecting insertion accuracy and locking reliability.

[0028] Therefore, the present invention provides an anti-shake locking structure for a vehicle-mounted beverage machine, such as... Figures 1 to 7As shown, the anti-shake locking structure includes a vehicle armrest box body 200 and a beverage machine body 100. The vehicle armrest box body 200 has a receiving cavity 210, and at least two insertion holes 220 are provided at the bottom of the receiving cavity 210. The bottom of the beverage machine body 100 is provided with a plug post 110 that is adapted to the plug post 220. When the plug post 110 is inserted into the plug post 220, the two form a preliminary positioning fit.

[0029] like Figures 4 to 7 As shown, an elastic dustproof skirt 300 is fixed to the inner wall edge of the insertion hole 220. In its natural state, the elastic dustproof skirt 300 closes the opening of the insertion hole 220. In its natural state, the skirt is a closed membrane or tongue-like structure, completely sealing the opening of the insertion hole 220. When each insertion post 110 is inserted into the insertion hole 220, the elastic dustproof skirt 300 undergoes elastic deformation and adheres tightly to the outer wall of the insertion post 110, forming a horizontal limiting constraint.

[0030] The function of the 300mm elastic dustproof skirt structure is as follows: (1) Dust and dirt prevention: When not in use, it prevents dust, beverage residue and other foreign objects from entering the plug hole 220, avoiding the decrease in plug accuracy and corrosion problems; (2) Elastic buffer: When the plug post 110 is inserted, the elastic dustproof skirt 300 is squeezed and undergoes elastic deformation, and its lip is tightly attached to the outer wall of the plug post 110, forming a 360° circumferential contact. The elastic restoring force generated by this contact applies a uniform radial constraint force to the plug post 110 in the horizontal direction, thereby eliminating the lateral swaying and impact noise caused by inertia during driving.

[0031] Without the elastic dustproof skirt 300, the plug hole 220 will be exposed for a long time, and dirt will easily accumulate inside the hole, making it difficult or even causing the plug post 110 to be inserted. In addition, the gap between the plug post 110 and the plug hole 220 in the horizontal direction cannot form effective damping. The beverage machine will have a noticeable shaking sensation in the accommodating cavity 210, resulting in a poor user experience and shortening the product life.

[0032] like Figures 1 to 5 As shown, the anti-shake locking structure also includes an electromagnetic lock device. The electromagnetic lock device includes an electromagnetic lock body 400 installed at the bottom of the accommodating cavity 210 and an electromagnetic lock attracting block 120 installed at a corresponding position on the bottom of the beverage machine body 100. When the electromagnetic lock body 400 is energized, it generates a magnetic force to attract the electromagnetic lock attracting block 120, thus locking the beverage machine body 100 vertically. Specifically, after the beverage machine body 100 is placed in position, the vehicle control system is energized to activate the electromagnetic lock body 400, generating a magnetic force to attract the electromagnetic lock attracting block 120, firmly pressing the beverage machine body 100 against the bottom of the accommodating cavity 210, thus achieving vertical locking.

[0033] The function of this electromagnetic lock device is: (1) Active locking: Fast locking and releasing are achieved through electronic control, without the need for additional manual operation; (2) Anti-bumps: The magnetic attraction force can prevent the beverage machine from jumping or detaching when the vehicle goes over bumps or brakes suddenly. If the electromagnetic lock is not used and only gravity or mechanical buckles are used, the beverage machine may jump off the entire container cavity 210 during severe bumps, causing equipment damage or safety hazards; mechanical buckles also have the risk of wear and tear from repeated insertion and removal, and fatigue fracture, while the electromagnetic lock is a non-contact locking type with no mechanical wear and higher reliability.

[0034] Furthermore, the passive elastic constraint provided by the elastic dustproof skirt 300 and the active magnetic constraint provided by the electromagnetic lock device form an independent locking system in two orthogonal directions: horizontal and vertical. Even if the electromagnetic lock fails due to circuit malfunction, the horizontal constraint force of the elastic skirt can still prevent the beverage machine from shaking violently; conversely, if the elastic skirt loses its elasticity due to aging, the vertical locking of the electromagnetic lock can still ensure that the beverage machine will not tip over, greatly improving the reliability and durability of the system. If only locking in one direction is used (such as only vertical locking of the electromagnetic lock), once the lock fails, the beverage machine will completely lose its constraint; if only the horizontal limit of the elastic skirt is relied upon, it cannot prevent the beverage machine from jumping up, and the limiting effect will significantly decrease after long-term elastic fatigue.

[0035] The anti-shake locking structure of the vehicle-mounted beverage machine of the present invention comprises an insertion hole 220 at the bottom of the vehicle armrest box accommodating cavity 210 and a corresponding insertion post 110 at the bottom of the beverage machine. An elastic dustproof skirt 300 is provided on the inner edge of the insertion hole 220, which closes the opening of the insertion hole 220 in its natural state. During installation, it deforms under pressure and adheres tightly to the outer wall of the insertion post 110, forming a horizontal limiting constraint. Simultaneously, an electromagnetic lock device is used, with lock bodies respectively provided at the bottom of the accommodating cavity 210 and the bottom of the beverage machine body 100. The magnetic attraction block, when powered on, generates magnetic attraction to achieve vertical locking, thus realizing dual fixation in both horizontal and vertical directions. This effectively prevents the beverage dispenser from shaking, spilling, or even flying off due to bumps while the vehicle is in motion, improving driving and riding safety. The elastic dustproof skirt 300 automatically seals the insertion hole 220 when not in use, preventing the accumulation of dust and debris, maintaining interior cleanliness and installation precision. Furthermore, the armrest box can be restored to independent storage function after the beverage dispenser is removed, taking into account practicality, convenience, and multi-functional utilization of interior space.

[0036] like Figure 1 , Figure 3 , Figure 4 and Figure 5As shown, in some embodiments, there are four insertion holes 220, which are arranged in a rectangular array at the bottom of the accommodating cavity 210. The insertion posts 110 are four cylindrical pillars, corresponding one-to-one with the insertion holes 220. This arrangement can form two orthogonal constraint pairs in the horizontal plane, significantly improving the resistance to torsion and roll: when the vehicle makes a sharp turn or bumps, any pair of diagonal insertion posts 110 will generate a reverse shear force, avoiding pillar breakage or hole wall wear caused by stress concentration; at the same time, the four sets of elastic dustproof skirts 300 simultaneously hug the insertion posts 110, further reducing the horizontal displacement of the beverage machine body 100. If the number of insertion holes is reduced to two 220, positioning can be achieved, but the torsional degree of freedom in the direction perpendicular to the line connecting the two holes is not fully constrained. After long-term vibration, the beverage machine is prone to slight rotation, which causes the electromagnetic lock attraction block 120 to misalign with the lock body, affecting the reliability of vertical locking. In this embodiment, the four-hole rectangular array eliminates the torsional degree of freedom through the over-positioning principle, ensuring the coaxial accuracy of the horizontal limit and the subsequent electromagnetic lock attraction, and improving the overall anti-shaking performance and service life.

[0037] like Figures 4 to 7 As shown, in some embodiments, the elastic dustproof skirt 300 is composed of several isosceles triangular elastic rubber sheets. The bottom edge 310 of the elastic rubber sheet is fixedly connected to the inner wall of the insertion hole 220, and the hypotenuse faces the central axis of the insertion hole 220. The ends 320 of each elastic rubber sheet fit together in the horizontal plane in the natural state.

[0038] Specifically, the bottom edge 310 of each elastic rubber sheet is firmly connected to the inner wall of the insertion hole 220 around its entire circumference by bonding or secondary injection molding, with the inclined edge extending towards the central axis of the hole and the apex located in the same horizontal plane. In its natural state, the inclined edges of adjacent rubber sheets overlap each other, and the apexes form a closed star shape, completely covering the opening of the insertion hole 220 to prevent dust and liquid from entering.

[0039] like Figure 6 and Figure 7 As shown, when the cylindrical insertion post 110 is inserted, each elastic rubber sheet is simultaneously and elastically flipped under radial thrust, with its hypotenuse tightly adhering to the outer wall of the insertion post 110, generating a uniform circumferential clamping force. The triangular geometry ensures stress dispersion during the flipping process, preventing permanent deformation. When the insertion post 110 is pulled out, each elastic rubber sheet instantly resets itself by its own rebound force, forming a fully enclosed seal again, achieving the dual functions of self-cleaning and dust prevention.

[0040] In some embodiments, the electromagnetic lock body 400 is electrically connected to the vehicle's central control system. The driver and passengers output on / off signals to the central control system through preset control buttons inside the vehicle to control the power on and off of the electromagnetic lock body 400.

[0041] Specifically, the central control system has a preset "beverage machine lock / unlock" function inside the vehicle. When the driver or passenger triggers the lock button, the central control system immediately outputs a high-level pulse to the electromagnetic lock drive module, causing the electromagnetic lock body 400 to generate an attractive force, completing the vertical locking. A subsequent trigger outputs a low-level pulse, de-energizing the electromagnetic lock body 400 and allowing the beverage machine to be freely removed. By integrating with the central control system, one-button operation and intelligent linkage with the entire vehicle scenario are achieved, improving both convenience and safety.

[0042] like Figure 3 As shown, in some embodiments, the anti-shake locking structure of the vehicle-mounted beverage machine also includes a contact-type limit switch 130 and a first prompting sound device (not shown in the figure); the contact-type limit switch 130 is located at the bottom of the accommodating cavity 210 or the bottom of the beverage machine body 100, and is electrically connected to the electromagnetic lock device and the first prompting sound device; when the plug-in post 110 is fully inserted into the plug-in hole 220 and the electromagnetic lock device is energized and engaged, the contact-type limit switch 130 is triggered, and the first prompting sound device emits an installation prompt sound according to the trigger signal. After the plug-in post 110 is fully inserted into the plug-in hole 220, the beverage machine body 100 presses down to trigger the limit switch. After the central control system detects the limit switch signal, it outputs a pulse signal to the electromagnetic lock body 400 to achieve adsorption, and at the same time drives the first prompting sound device to emit a "beep" prompt sound, indicating that the installation and locking are completed simultaneously; If the limit switch is not triggered, the central control system will prevent power supply to the electromagnetic lock and will prompt "Please place the beverage machine again" to avoid insufficient suction force caused by the electromagnetic lock being only partially or completely attracted.

[0043] This will enable the following functions: (1) Double confirmation: mechanical positioning + electronic engagement to prevent users from not inserting it all the way in; (2) Instant feedback: The prompt sound replaces visual confirmation, so the driver does not need to turn his head to look, thus improving driving safety; (3) Fault self-check: If the prompt sound does not sound and the system has sent a lock command, it can be determined that there is a fault in the limit switch or the circuit, which is convenient for timely repair.

[0044] Without the limit switch and the prompt sound, the user may not fully insert the electromagnetic lock due to tactile error or obstructed vision, leaving it in a weakly attracted state. When the vehicle passes over speed bumps, the beverage machine may be shaken off, losing its vertical locking function. This embodiment significantly reduces the probability of misoperation and improves locking reliability through a closed loop of "mechanical triggering - electronic control confirmation - sound feedback".

[0045] In some embodiments, the anti-shake locking structure further includes a locking status sensor (not shown in the figure) and a second prompting sound device (not shown in the figure), forming a "detection-feedback" closed loop to solve the potential problem of false locking where the electromagnetic lock is "energized but not actually engaged". The locking status sensor is disposed on the electromagnetic lock body 400 or the electromagnetic lock engagement block 120 to detect the actual adsorption distance between the electromagnetic lock body 400 and the electromagnetic lock engagement block 120; The second prompt sound device is electrically connected to the locking status sensor and the electromagnetic lock device; When the electromagnetic lock device is powered on and the locking status sensor detects that the adsorption distance is less than or equal to the preset threshold, the second prompting sound device emits a prompt sound indicating successful locking. When the electromagnetic lock device is powered on but the locking status sensor does not detect that the adsorption distance is less than or equal to the preset threshold within a preset time, the second prompting sound device emits a locking failure alarm sound.

[0046] Specifically, the locking status sensor can be a miniature Hall effect sensor or an inductive proximity switch, embedded in the center of the magnetic lock body's adsorption surface, or correspondingly mounted on the bottom surface of the magnetic lock's adsorption block. The sensor's detection end faces the mating gap between the lock body and the adsorption block, measuring the actual adsorption distance L between them in real time. A second prompting sound device (such as a patch buzzer or a car audio driver unit) is electrically connected in series with the sensor and the magnetic lock drive module in the control module.

[0047] When the driver or passenger triggers the locking command, the system initiates the following timing logic: When the electromagnetic lock body is energized, it generates a magnetic field, and the attraction block is pulled towards the lock body by the magnetic force. If the sensor detects that the attraction distance L is less than the threshold, it is determined to be "true lock". The control module drives the second prompt sound device to emit a short, high-frequency prompt sound, indicating that the beverage machine has been safely locked.

[0048] If the sensor consistently detects that L is greater than the threshold after the electromagnetic lock is powered on, it is determined to be a "false lock". The control module drives the second prompt sound device to emit a long low-frequency alarm sound and displays "Beverage machine not locked, please place it again" on the instrument panel, preventing the vehicle from entering the driving ready state.

[0049] This structure accurately identifies the locking status by directly detecting the physical distance, rather than through traditional current detection. Simply energizing the electromagnetic lock does not guarantee a tight seal between the contact surfaces—if beverage residue or dust particles adhere to the contact surface, even with power, the actual gap may still exceed 0.5 mm, resulting in a magnetic force attenuation of over 60%, making the beverage dispenser susceptible to dislodgement when a vehicle goes over speed bumps. The sensor detects the L value, essentially monitoring the magnetic reluctance along the magnetic force transmission path to ensure effective conversion of magnetic force into mechanical clamping force. The preset threshold is derived from magnetic field simulation and durability testing to avoid misjudgments.

[0050] Without sensors and a second audible alert device, users can only rely on the electromagnetic lock's power indicator light to determine if the lock is falsely locked, making it impossible to identify false locks. This embodiment provides immediate feedback through differentiated audible alerts, reducing the rate of missed lock failures and eliminating the need for visual confirmation by the user, thus improving driving safety.

[0051] In some embodiments, to simplify the system architecture and reduce costs, the first and second prompt sound devices can be configured as the same physical sound unit, with differentiated sound outputs achieved through software or circuit logic. Using a single sound device reduces the need for a buzzer, a set of drive circuitry, and independent installation space, thereby lowering overall material costs and simplifying wiring harness layout and assembly processes.

[0052] In some embodiments, the elastic dustproof skirt 300 is made of elastic rubber and is fixedly connected to the edge of the insertion hole 220 by bonding or insert injection molding. The bonding method is simple and low-cost; the insert injection molding method achieves complete sealing and eliminates the risk of adhesive aging. Both methods ensure that the root of the elastic dustproof skirt 300 is not subjected to concentrated stress during insertion and removal, avoiding tearing; at the same time, the rubber material is resistant to beverages and dust, and can maintain its elasticity and resilience even after long-term use, ensuring the long-term effectiveness of the sealing and limiting functions.

[0053] In some embodiments, the electromagnetic lock device uses 12V or 24V DC power supply, and its power supply line is adapted to the vehicle power system. It can be adapted to mainstream passenger car and commercial vehicle platforms without the need for an external converter, thereby improving versatility and reliability, while meeting the standardized interface requirements of the vehicle power system.

[0054] In some embodiments, the plug post 110 and the plug hole 220 are clearance-fitted, which facilitates one-handed operation and ensures that the radial clamping force of the elastic dustproof skirt 300 is sufficient to counteract the horizontal sway caused by the clearance; at the same time, it avoids excessive compression of the rubber sheet and premature fatigue caused by interference fit.

[0055] In some embodiments, to improve locking reliability and provide visual feedback on the status, the anti-shake locking structure is further equipped with a locking status sensor and a differentiated prompting device. The locking status sensor may be a Hall effect sensor or a micro switch, installed on the adsorption surface of the electromagnetic lock body 310 or at the corresponding position of the electromagnetic lock adsorption block 320, to detect the actual adsorption distance between the lock body 310 and the adsorption block 320.

[0056] When the driver or passenger triggers the locking command, the system executes the following logic: Successful locking status: If the electromagnetic lock is powered on and the Hall sensor detects that the magnetic field strength reaches the preset threshold, or the micro switch is pressed and triggered, it is determined to be "locked in place". At this time, the prompting device emits a short high-frequency prompt sound (such as a 0.5-second, 3 kHz "beep" sound), indicating that the beverage machine has been safely locked. Locking failure status: If the sensor does not detect the positioning signal within 1 second after power-on, it is determined as "locking failure". At this time, the prompting device will emit a long low-frequency alarm sound (such as a "beep" sound lasting 2 seconds and 1 kHz) and display the warning message "Beverage machine not locked, please place it again" on the instrument screen.

[0057] This sensor and differentiated prompting system solve the blind spot problem of relying solely on the electromagnetic lock's power-on status without confirming the actual physical engagement. Electromagnetic locks can experience false locking due to foreign objects on the engagement block surface, positional deviations, or insufficient voltage, resulting in "powered but not fully engaged" situations. In such cases, vehicle vibrations could still cause the beverage machine to detach. By directly detecting the physical distance through the sensor, a dual confirmation of the locking status (electrical signal + physical signal) is achieved, reducing the missed detection rate of locking failures to near zero. Simultaneously, different prompting sounds allow the driver to judge the locking result auditorily without needing to look at the screen, improving driving safety. Without this sensor system, users can only judge by the electromagnetic lock's power-on indicator light, unable to identify false locking states, posing a risk of the beverage machine accidentally detaching while driving. The differentiated prompting sounds provide intuitive user feedback, shortening troubleshooting time.

[0058] This invention also provides a vehicle armrest box, which includes the anti-shake locking structure of the aforementioned vehicle beverage machine. The body of the vehicle armrest box also serves as the cavity wall of the receiving cavity 210, and the anti-shake locking structure of the vehicle beverage machine of any of the above embodiments is fully integrated therein; the insertion hole 220, the elastic dustproof skirt 300, and the electromagnetic lock body 400 are all pre-embedded in the bottom of the body, and the electromagnetic lock power supply line shares the vehicle power interface with the armrest box's built-in wiring harness. Thus, the armrest box can be directly adapted to the beverage machine body 100 at the factory without additional brackets or modifications, realizing modular assembly of "one box for two uses" and inheriting all functions of anti-shake, dustproof, and intelligent locking.

[0059] The present invention also provides a vehicle-mounted beverage machine, which includes a beverage machine body 100 and at least two plug-in pins 110 and an electromagnetic lock attraction block 120 disposed at the bottom of the beverage machine body 100; the plug-in pins 110 are configured to be plugged into the plug-in holes 220 at the bottom of the vehicle armrest box accommodating cavity 210 to achieve horizontal limiting; the electromagnetic lock attraction block 120 is configured to be magnetically attracted to the electromagnetic lock body at the bottom of the accommodating cavity 210 to achieve vertical locking.

[0060] The present invention also provides a vehicle including the aforementioned vehicle-mounted armrest box. The armrest box is fixed to the floor or central tunnel between the two front seats of the vehicle, and its electromagnetic locking device is electrically connected to the vehicle's power system via the vehicle's wiring harness and controlled by the vehicle's central control system. Thus, during vehicle operation, the beverage machine can automatically achieve horizontal limiting and vertical locking, preventing it from shaking, making abnormal noises, or falling off during bumps, sudden braking, or turning, improving driving safety and comfort, and enabling plug-and-play operation of the beverage machine without additional modifications.

[0061] Installation and usage process: The user inserts the plug 110 at the bottom of the beverage machine body 100 vertically into the plug hole 220. The elastic dustproof skirt 300 is stretched open and tightly wraps around the plug 110, at which point the beverage machine has completed its automatic horizontal positioning. Subsequently, the vehicle system is powered on, and the electromagnetic lock body 400 attracts the suction block, firmly locking the beverage machine. During disassembly, the system is powered off, the electromagnetic lock is released, the user lifts the beverage machine upwards, the plug 110 is pulled out, and the elastic dustproof skirt 300 automatically springs back to its original position, sealing the plug hole 220 again.

[0062] Through the above structural combination, the present invention achieves the synergistic effect of horizontal elastic damping constraint and vertical active magnetic locking, solving the problems of unreliable single-direction locking, easy accumulation of dirt, and insufficient impact resistance of traditional structures, and significantly improving the stability, quietness and service life of vehicle-mounted beverage machines under complex driving conditions.

[0063] It should be noted that, where there is no conflict, the features in the embodiments of this invention can be combined with each other.

[0064] The above description is merely a preferred embodiment of the present invention and is not intended to limit the invention. Various modifications and variations can be made to the present invention by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
