Electric-assisted supermarket trolley

Abstract

Electric-assisted supermarket trolley system. The invention is characterized by the addition of motors to the rear wheels of a standard trolley and is equipped with an indoor and outdoor geolocation system. Triggers are used to control the trolley. It has a sufficiently powerful battery to supply power to the various motors. The shopping tray is removable and can be raised or lowered using a button. An electronic system manages the motors and any safety features.

Description

Title of the invention: Electrically assisted supermarket trolley TECHNICAL FIELD OF THE INVENTION

[0001] Electric assist supermarket trolley to help people who have difficulty pushing their trolley. TECHNOLOGICAL BACKGROUND OF THE INVENTION

[0002] Currently, supermarkets are generally equipped with manually operated shopping trolleys. People gradually fill the trolley, and as a result, it becomes increasingly heavy. It therefore becomes difficult both to push and to control it.

[0003] In addition, heavy loads that are at the bottom of the trolley can be difficult to retrieve when the user unloads their shopping. GENERAL DESCRIPTION OF THE INVENTION

[0004] The present invention aims to avoid the disadvantages of the prior solution and to improve user comfort.

[0005] The aim is to have an electrically assisted trolley in order to simplify their movements and the handling of groceries or objects located at the bottom of the trolley.

[0006] Equipped with a high-performance battery and two electric motors, one on each wheel, and controlled by two triggers, the cart moves forward on its own, allowing elderly or disabled users to avoid pushing it while shopping. Furthermore, a motorized lifting platform, adjustable in height via a button, ensures the cart's base is always at the correct height, minimizing the effort required from users.

[0007]

[0008] The electrically assisted supermarket trolley is characterized by:

[0009] 1: Electric triggers which allow the carriage to move forward and turn.

[0010] 2: Electronic system and battery for powering the electric motors and the related services

[0011] 3: Electric wheels that allow the cart to move forward

[0012] 4: Platform for dropping off groceries or objects; it is motorized and can move vertically using a worm gear and chain or belt system

[0013] 5: Worm gear system with chain and / or belt that allows for raising or lower the drop-off tray

[0014] 6: Geolocation and data transmission system (GPS and GSM chip). The system allows alerts to be sent to the supermarket if a predefined zone is exceeded.

[0015] 7: Support for smartphone or touchscreen for guidance during races (possible changes depending on the service)

[0016] 8: Battery charging connector

[0017] 9: Button that allows raising or lowering the racing platform

[0018] 10: Motor that drives the chain or belt system to move up or down the plateau (4)

[0019] 11: Upper limit switch

[0020] 12: Lower limit switch

[0021] Developments in the electrically assisted supermarket trolley

[0022] Developments are possible in order to guarantee different companies services of varying quality:

[0023] -a geolocation chip (GPS type) and a data transmission chip (GSM type) would be integrated into the electrically assisted trolley in order to signal as soon as a trolley leaves the defined perimeter to prevent theft.

[0024] -a smartphone holder (of the user) or a touch screen on the trolley to help the user find specific products in the aisles and show them where to find them (interactive search and aisle to find the product).

[0025] - An application, compatible with Android or Apple, would allow the user to choose their supermarket and import their shopping list, guiding them through the aisles to minimize movement while shopping. This would be similar to how a GPS guides cars (this would be possible thanks to the inserted GPS chip) and a database of location information within the supermarket would provide real-time kinematic data. Brief description of the drawings

[0026] The invention will be better understood and other features and advantages will become more apparent upon reading the description given below.

[0027] Fig. 1 represents a prototype diagram of the electrically assisted trolley with the elements that compose it. DESCRIPTION OF THE INVENTION

[0028] Fig. 1 represents a 3D view of the electrically assisted cart.

[0029] Using the two triggers (1) positioned on the bar used to push the carriage With electric assistance, the user can choose to move the cart forward or turn it by pressing one or two triggers (1). As soon as a trigger (1) is activated, the electronic system (2) activates the wheel motors (3) and allows the cart to operate.

[0030] The button (9) located on the side allows the race drop-off platform (4) to be raised or lowered. A system based on a motor (10) located under the platform The removal mechanism (4) drives a worm gear system (5). Once the removal platform (4) touches the upper limit switch (11), the removal platform (4) can no longer move upwards. The operation is identical for the lower limit switch (12), which stops the motor's descent.

[0031] The geolocation system (6) integrated on the side of the trolley allows the trolley to be located outside and inside, and in the event that the trolley crosses a defined perimeter, will send an alert message to the security system.

[0032] The trolley could also be equipped with a smartphone holder or integrate a screen (7) to help and guide the user in the store and indicate as closely as possible the product sought.

[0033] A charging connector (9) located on the side of the trolley is intended to allow the trolley to be charged and to maintain a sufficient charge level for the next use.

[0034] List of reference symbols:

[0035] 1: Electric triggers which allow the carriage to move forward and turn.

[0036] 2: Electronic system and battery for powering electric motors and related services

[0037] 3: Electric wheels that allow the cart to move forward

[0038] 4: Platform for dropping off groceries or objects; it is motorized and can move vertically using a worm gear and chain or belt system (5)

[0039] 5: Worm gear system with chain and / or belt that allows for raising or lower the drop-off platform (4)

[0040] 6: Geolocation and data transmission system (GPS and GSM chip). The system allows alerts to be sent to the supermarket if a predefined zone is exceeded.
