Description

Technical field to which the invention relates

This invention relates to a technical solution for devices and batteries that enables the replacement of device batteries, primarily mobile devices, without interrupting the power supply.

The field of technology to which the present invention relates is designated by the International Classification of Patents as H02J, H04B, H04M.

Technical problem

The technical problem that is solved by the present invention is the interruption of the device's power supply, which occurs during the duration of the procedure of changing exhausted/empty with a new/full battery, since the interruption of the device's power supply results in the interruption of any operation of the device that the user of the device was performing until then, regardless of how short the battery replacement procedure lasted.

The need to solve the indicated technical problem is increased by the fact that after the replacement of an empty/exhausted battery with a full/new battery, no matter how short the replacement and power interruption, it is necessary to wait a relatively long time for the entire operating system of the device to boot up in order to be able to continue working of the device, which implies that the programs in which the work was carried out until then must be reopened, and only then can the previous work with the device be continued.

The technical problem generally refers to all devices that contain batteries as an autonomous source of electricity that serves to power the device's consumption during operation so that they can work even when they are not connected to a stable source of electricity.

The battery capacity of these devices is such that it provides power consumption for the operation of the device for a certain time, as a rule, for several hours, after which it is necessary to either connect the device to a stable source of electricity to charge the battery or replace the empty battery with a new one, i.e. a full one.

Such solutions are usually found in mobile devices, smartphones, laptops, tablets, etc. Mobile phones, especially smartphones or tablets, have an increasing number of increasingly comprehensive functions and increasingly powerful processors and increasingly demanding applications, which leads to an ever-increasing consumption of electricity during operation and causes problems. which occur due to rapid exhaustion, or discharge of the battery, or short battery life.

For this reason, these devices must be connected to the charger after shorter and shorter periods of operation. When they are connected to a charger, it is impractical to use them because they must be connected to a stable source of electricity by cable.

Batteries can be replaced, but with today's versions of the mentioned devices and batteries, this is sometimes a demanding procedure for the average user that takes quite a long time, and on some devices it is not even possible to replace the battery because it is enclosed in the device case. Otherwise, the battery replacement itself implies the implementation of a specific procedure that includes the removal of a specific cover in order to release the empty battery that is located in the space for housing the battery in the device case, removing the battery from that space and inserting a full/charged or new battery into the space provided and placing and fixing the battery cover.

Known state of the art

As is known for the operation of mobile devices, smartphones, laptops, tablets, etc., the necessary electricity is provided by batteries, which today are offered in an extremely large number of types and designs, and each of them has a certain full capacity expressed with the associated amount of mAh. The operation of a device that is powered by its own battery leads to the discharge of that battery, i.e. the reduction of its capacity, where care must be taken not to exceed the lower allowable capacity limit when discharging the battery, below which the battery is not recommended to be used, but needs to be charged to full capacity or its replacement with a new or charged battery. Usually, a battery whose discharged capacity has reached or is close to the lower allowable capacity limit is called an "empty" battery, although it is not actually a completely discharged battery, since it is still capable of powering the associated device for some time, while a charged or brand new battery is included called "full" battery.

In accordance with the above, in the following text, the term "empty battery" means a battery whose capacity has decreased to the lower permissible limit, which means that it is not actually a completely discharged battery, since it is still capable of powering the associated device for some time, while a full battery means a charged one. or a brand new battery.

According to the known state of the art, most mobile phones or smartphone devices are supplied with batteries whose capacity is sufficient to power the device in a certain intended mode of operation during a certain number of working hours which, as a rule, expire at the end of the working day, in which way it is possible to spend the night charging the battery and restoring its capacity to the full amount.

If the device's operation reaches the lower limit of the battery capacity before the planned end of the day's work while using the device, and there is still a need to continue using the device, it is necessary to either charge the empty battery while simultaneously using the device or replace the empty battery with a full one.

Charging an empty battery while using the device at the same time has a number of disadvantages, so replacing an empty battery with a full one is a better choice.

In the case of most cell phones or smartphone devices, according to the known state of the art, the batteries 1.1 are placed in the housing 1.5 of the device, which has a cover on the rear panel that must be removed to change the battery in order to reach the battery 1.1, which is inserted in the space 1.2 for housing the battery in the device.

Before the battery can be removed, the device must be turned off, during which any work carried out on it must be stopped and the device remains without power during the replacement procedure. When removing the battery from space 1.2 or inserting it into space 1.2, it occupies position 2.1, whereby this is done in one of the directions 2.2., depending on whether the battery is being removed or inserted into space 1.2.

When the battery is inserted in the device, the side 1.6 of the battery, where the contacts 1.3 on the battery are located, faces the side 1.7 of the space in the device for housing the battery, where the contacts 1.4 are located in the device case, in such a way that the contacts 1.3 cover the batteries and connect them to contacts 1.4 in the device housing, which establishes an electrical connection between contacts 1.3 on the battery and contacts 1.4 in the device housing, i.e. from the battery 1.1 it is possible to supply electricity to the device whose housing 1.5 contains the built-in associated components.

When the battery 1.1 is removed from the housing 1.5 of the device, contacts 1.3 on the battery and contacts 1.4 in the device housing are separated, and at that moment the power supply to the device is interrupted. When inserting the battery 1.1 into the space 1.2 in the battery housing device, contacts 1.3 on the battery and contacts 1.4 in the device housing are connected and the device then receives power from the new/charged battery. After replacing the batteries, the device is turned on again, and it is necessary to wait a short time for the entire operating system to boot up in order to be able to continue with the work that was going on until the device was turned off.

With all solutions according to the known state of the art, during battery replacement, the device's power supply is interrupted with the well-known unwanted consequences described above. With some solutions, the only thing achieved is shortening the duration of the battery replacement procedure and thus the duration of power interruption. Thus, the technical solution according to patent file US2006/0226804 foresees the design of batteries with sliding channels on two side narrow surfaces and corresponding sliders in the device housing, which enables a certain shortening of battery replacement time.

On the other hand, in the patent file US2003/0003949 a technical solution is presented with certain hooks on the housing of the mobile device with which the battery is mechanically attached to the housing, which makes it possible to shorten the time of battery replacement thanks to the technical solution that instead of a cover and screws, hooks are overlooked so that with a simpler, easier and faster release of the hooks, both the separation of the battery from the housing and the attachment of the new battery with these hooks are achieved in a shorter time.

The essence of the invention

The essence of the technical solution according to the invention consists in the fact that the contacts on the battery as well as the contacts in the device housing are located and designed in such a way that the procedure for replacing an empty battery with a full one can be carried out without interrupting the power supply of the device, whereby space 1.2 in the device is for housing the battery completely open on both sides of the housing 1.5, in which way a complete penetration 3.6 through the device housing is formed.

This is reflected in the fact that the contacts on the battery of the corresponding design, which according to the state of the art are located on the side 1.6, according to the invention are located on one of the two larger side surfaces 3.3 of the battery, while the contacts in the device housing are of the corresponding design, which according to the state of the art techniques located on the narrow side 1.7 of the space in the device for housing the battery, according to the invention located at the bottom of the space 1.2 in the housing of the device for housing the battery.

The designs of the contacts both on the battery 1.1 and in the housing 1.5 of the device can be in two combinations.

The first of these combinations consists in the fact that the contacts on the battery are designed as sliding 3.2 contacts in the form of strips, in which case the contacts in the device case are designed as point 3.7 contacts.

The second combination envisages that the contacts on the battery are made as point 6.1 contacts, while the contacts in the device housing in that case are made as sliding 6.2 contacts in the form of strips.

The point contacts 3.7 and 6.1, which can be made in the form of a square or a circle, have sides, or diameter, which are equal to the width of the strip of the sliding contact 3.2 and 6.2 or differ accordingly.

In order to achieve uninterrupted power supply to the device during battery replacement, it is necessary that the distance Rt of the point contacts both those 3.7 in the case and those 6.1 on the battery should be coordinated with the length Lk of the sliding contacts both those 3.2 on the battery and those 6.2 in the case and that in such a way that, when replacing the battery, in which the full one pushes the empty battery towards the other side of the penetration 3.6 through the device housing, the contacts on the full battery are connected to the contacts in the device housing while the contacts of the empty battery are connected to the contacts in the device housing so that at one moment the device is powered by both batteries in a parallel connection and that such a state lasts for a certain time after which the contacts of the empty battery, which is pushed by the full battery, do not separate from the contacts in the device case, when only the full battery takes over the power supply of the device in which the housing is fixed in its final position.

According to the invention, the battery is placed in the penetration space 3.6 through the device housing, in such a way that its surface 3.3, on which the sliding 3.2 or point 6.1 contacts are located, is facing the bottom of the space 1.2 in the device for housing the battery, on which bottom are the point 3.7 or sliding 6.2 contacts, thanks to which connections are established between the sliding and point contacts on the battery and in the device housing, and the device is powered from the battery that is inserted in the described manner, and the battery itself is in the middle of space 1.2 in the device for housing the battery and is fixed with suitable elastic holders , one of the possible embodiments of which ensures that the elastic projection 3.9 of the elastic holder, located in the housing, enters the recess 3.8 in the battery.

The elastic battery holders consist of a piston 7.2 with a ball tip, which is located with a spring 7.3 in a housing 7.1. The ball tip of the piston 7.2, under the pressure of the spring 7.3, enters the recesses 3.8 in the battery and thus holds it in place.

It is desirable to achieve that the sides of the battery, fixed in the described way, are aligned with the case, thanks to which there is no need for additional covers on the penetration openings 3.6 through the case, and thus the utilization of the space of the device is significantly increased.

The procedure for replacing the battery of the device without interrupting the power supply is carried out simply, easily and quickly in such a way that the full battery, which according to the design of the contacts on it should be identical to the empty battery being replaced, is placed in the same position and parallel to the empty battery and its associated on the side, the side of the empty battery pushes with a certain force towards the other side of the penetration 3.6, thanks to which the elastic projection 3.9 in the housing jumps out of the recess 3.8 in the battery, which enables the empty battery to slide towards the other side of the penetration 3.6, whereby the point contacts are in mutual contact and slide by the sliding contacts so that the power supply of the device from the empty battery is not interrupted but continues until the contacts of the new battery, sliding, 3.2 or dotted 6.1, come into contact with the contacts in the case, dotted 3.7 or sliding 6.2, when the device is powered from both batteries in parallel connection, so that after further pushing, the old battery continues to slide towards at the other end of the penetration 3.6, during which time the connection between the contacts on the battery and the contacts in the device case is interrupted, when the new battery takes over the device's independent power supply and slides behind the empty battery until the elastic projection 3.9 in the case enters the recess 3.8 in the battery, which achieves position fixation new batteries and an empty battery falls out of the penetration area 3.6 while a full battery permanently powers the device.

Acceleration of placing a full battery in the correct position when replacing batteries can be achieved by making protrusions 3.4 on the battery, while a sliding channel 3.10 is made in the penetration 3.6 through the housing.

As a result of the battery replacement procedure described above, there is no interruption of the device's power supply, but the device's power supply takes place in such a way that for a while at the very beginning of the procedure of replacing the empty battery, the power is supplied from that empty battery, and after that the power supply is supplied from both the empty and full batteries which act as two parallel sources, after which the power is taken over by the full battery itself and the empty battery is removed from the device.

As a result of the technical solution according to the subject invention, the device does not have to be turned off when the battery replacement procedure is carried out, except that there is no interruption of the power supply. The empty battery is replaced with a full one, and the entire replacement procedure according to the subject invention takes a few seconds. This procedure greatly facilitates the use of the device and is more practical because it never has to be connected by a cable for charging while the device is operating, the time of active use of the device is extended because when the battery is empty it is replaced by a full battery. The invention can be applied to all modern mobile devices.
