Storage device with status indication and status indication structure

Abstract

The application provides a storage device with state indication and a state indication structure. The storage device with state indication comprises a first part of the device, a second part of the device which is opposite to the first part of the device to form a storage space, and a state indication structure which is arranged between the first part of the device and the second part of the device. The state indication structure comprises a touch element arranged on the first part of the device, a passive element assembly arranged on the second part of the device and triggered by the touch element, and a reset element which drives the passive element assembly to reset when the touch element and the passive element assembly are released from the released state. Compared with the state indication structure which needs an energy storage unit, the storage device with state indication provided by the application can improve the effective space carrying rate of the storage device without arranging the energy storage unit. In addition, the opening and closing state indication is not easy to fail because the energy storage unit is not exhausted to cause the failure of the opening and closing state indication.

Description

Technical Field

[0001] This application relates to the field of security protection technology, and in particular to a storage device with status indication and a status indication structure. Background Technology

[0002] In the security field, the safety of storage devices for valuables must be considered when moving them. The open / closed state of these devices is one aspect of security. For example, items stored in devices that are not fully closed may spill or fall out during movement, posing a risk of damage.

[0003] In existing technologies, the opening and closing status of storage devices can be indicated using indicator lights. It's easy to understand that this necessitates the inclusion of a corresponding energy storage mechanism, such as a battery, within the storage device.

[0004] In the process of developing the existing technology, the inventors discovered that:

[0005] On the one hand, the installation of energy storage mechanisms will occupy some space in the storage device. The larger the space occupied by the energy storage mechanism, the smaller the space available for storing valuables in the storage device or equipment.

[0006] On the other hand, when the energy storage is depleted, the opening and closing status indication function of the storage device fails.

[0007] Therefore, there is a need for a technical solution that has a high effective space carrying capacity and whose opening and closing status indication function is not prone to failure. Summary of the Invention

[0024] A limiting element is positioned between the back plate and the indicator plate to prevent the indicator plate from over-resetting.

[0025] Furthermore, the indicator panel is also equipped with a tail fin;

[0026] When the trigger abuts against the tail fin and overcomes the restoring force of the reset element, the indicator plate rotates relative to the back plate;

[0075] To make the objectives, technical solutions, and advantages of this application clearer, the technical solutions of this application will be clearly and completely described below in conjunction with specific embodiments and corresponding drawings. Obviously, the described embodiments are only a portion of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0076] Please refer to Figures 1 to 2 A storage device 100 with status indication includes:

[0077] Device First Division 11;

[0078] The second part of the device 12 is coupled with the first part 11 of the device to form a storage space;

[0079] A status indication structure 13 is disposed between the first part 11 and the second part 12 of the device;

[0080] The status indication structure 13 includes:

[0081] A trigger 131 is disposed in the first part 11 of the device;

[0082] The passive component assembly 132, which is triggered by the actuator 131, is located in the second part 12 of the device;

[0083] When the trigger 131 is released from the state of being released from the passive component 132, it drives the reset component of the passive component 132 to reset.

[0084] The term "storage device 100" is a non-precise description of an item storage device or equipment. Functionally, the storage device 100 is primarily used for storing and facilitating the movement of items. In its specific implementation, the storage device 100 can be a box, cabinet, container, jar, or other irregularly shaped storage device. It is readily understood that the specific form of the "storage device 100" here does not constitute a substantial limitation on the scope of protection of this application.

[0085] The first part 11 and the second part 12 of the device are two relatively independent sections of the storage device 100. These two sections together form the main body of the storage device 100. Here, "main body" refers to the proportion of space occupied by the storage device 100 and does not include comparisons with the value of other sections of the storage device 100. The first part 11 and the second part 12 together define, or enclose, the storage space for storing items. In one specific implementation provided in this application, the overall shape of the storage device 100 is typically a flat box shape that is easy to carry or move. Functionally, the first part 11 and the second part 12 can be represented as a lid and a box body primarily used for storage, respectively. In terms of size or volume, the two parts can be the same or different. The first part 11 and the second part 12 are typically made of hard alloy or other hard materials that are difficult to damage by force, to protect valuable items inside. The first part 11 and the second part 12 are joined together. In other words, the two parts together form a whole that is easy to store. The distinction between the first part 11 and the second part 12 of the device using "first" and "second" is only for the convenience of description; in actual implementation, the two names can be used interchangeably.

[0086] A status indicator structure 13 is disposed between the first portion 11 and the second portion 12 of the device. The status indicator structure 13 is used to indicate the open or closed state of the first portion 11 and the second portion 12 of the device. That is, it indicates whether they are in an open or closed state.

[0087] Status indication structure 13 includes:

[0088] A trigger 131 is disposed in the first part 11 of the device;

[0089] The passive component assembly 132, which is triggered by the actuator 131, is located in the second part 12 of the device;

[0090] When the trigger 131 is released from the state of being released from the passive component 132, it drives the reset component of the passive component 132 to reset.

[0091] The actuating element 131 is mainly used to provide a triggering force mechanically or mechanically. The actuating element 131 can be integrally formed or fixedly connected to the first part 11 of the device. The fixed connection can be welding, riveting or other assembly connection.

[0092] The passive component 132 is at least partially triggered by the actuator 131. The passive component 132 is disposed in the second part 12 of the device.

[0093] The reset component is used to reset the passive component 132 when the trigger 131 is released from the state of being released from the passive component 132.

[0094] Compared to the status indication structure 13 that requires an energy storage unit, the storage device 100 with status indication provided in this application does not require an energy storage unit, which can improve the effective space carrying capacity of the storage device 100. In addition, the opening and closing status indication function will not fail due to the depletion of the energy storage unit, thus the opening and closing status indication is less likely to fail.

[0095] In one specific embodiment provided in this application, the passive component assembly 132 includes:

[0096] The back plate 1321 is fixedly installed on the second part 12 of the device;

[0097] Indicator plate 1322 moves relative to back plate 1321;

[0098] One end of the reset component is connected to the indicator plate 1322, and the other end is connected to the back plate 1321.

[0099] The back plate 1321 is fixedly installed on the second part 12 of the device. The back plate 1321 serves to isolate the indicator plate 1322, or rather, to limit the movement space of the indicator plate 1322, preventing adverse effects on the second part 12 of the device when the indicator plate 1322 moves. It also prevents stored items from adversely affecting the indicator plate 1322. The back plate 1321 can be selected in a specific shape as needed; in one specific implementation provided in this application, it is a sheet or plate. For effective protection of the indicator plate 1322, hard metal or hard alloy can be primarily used. Alternatively, the surface of the back plate 1321 can be covered with flexible rubber, leather, or other materials to protect stored items.

[0100] The indicator plate 1322 moves relative to the back plate 1321. Different positions of the indicator plate 1322 relative to the back plate 1321 indicate different opening and closing states between the first part 11 and the second part 12 of the collection device 100.

[0101] Furthermore, in one specific embodiment provided in this application, the indicator panel 1322 has an indicator area 1323;

[0102] The storage device 100 is also provided with an observation window so that the status changes of the storage device 100 can be observed through the indicator area 1323.

[0103] The indicator plate 1322 can be shaped as needed. In one embodiment provided in this application, the indicator plate 1322 has a circular head and a rod-shaped arm. The circular head has a large area, making it easy to observe. The indicator area 1323 is located on the circular head. The rod-shaped arm is mainly used to drive the circular head. The rod-shaped arm is slender, which can reduce weight. The storage device 100 has an observation window. Changes in the indicator area 1323 can be observed through the observation window. In a specific embodiment provided in this application, the color of the indicator area 1323 is different from the color of the back plate 1321. Thus, when the indicator area 1323 of the indicator plate 1322 moves, the color seen through the observation window will change, thereby indicating the changes in different opening and closing states between the first part 11 and the second part 12 of the device. The indicator area can also be distinguished from the back plate by marking text, characters, patterns, etc.

[0104] Furthermore, in one specific embodiment provided in this application, the indicator plate 1322 is also provided with a tail fin;

[0105] When the trigger 131 abuts against the tail fin and overcomes the restoring force of the reset member, the indicator plate 1322 rotates relative to the back plate 1321.

[0106] When the trigger 131 disengages from the tail fin, the indicator 1322 is reset by the action of the reset element.

[0107] Furthermore, in one specific embodiment provided in this application, the indicator plate 1322 is also provided with a tail fin;

[0108] When the trigger 131 abuts against the tail fin and overcomes the restoring force of the reset member, the indicator plate 1322 translates relative to the back plate 1321.

[0109] When the trigger 131 disengages from the tail fin, the indicator 1322 is reset by the action of the reset element.

[0110] Furthermore, in one specific embodiment provided in this application, the tail fin is bent to form an abutment extension area 1324.

[0111] The indicator plate 1322 is also provided with a tail fin so that the trigger 131 can activate the indicator plate 1322. In one specific implementation provided in this application, the tail fin is bent to form an abutment extension area 1324. The process of bending the tail fin to form the abutment extension area 1324 is easy and low-cost to implement. When the abutment extension area 1324 is large, it is easily triggered by the trigger 131 and is less prone to failure.

[0112] One end of the reset element is connected to the indicator plate 1322, and the other end is connected to the back plate 1321. In the embodiments provided in this application, the reset element can be a spring. The spring can be stretched or compressed, and the restoring force causes the indicator plate 1322 to return to its original position.

[0113] Furthermore, in one specific embodiment provided in this application, the passive component assembly 132 further includes a limiting component 1325;

[0114] The limiting member 1325 is disposed between the back plate 1321 and the indicator plate 1322 to prevent the indicator plate 1322 from over-resetting.

[0115] The limiting member 1325 is used to prevent the indicator plate 1322 from over-resetting. In practice, the limiting member 1325 can be implemented as a stop. The limiting member 1325 only needs to ensure that the indicator plate 1322 returns to a preset position to prevent damage caused by over-limit.

[0116] Furthermore, in one specific embodiment provided in this application, the passive component assembly 132 further includes a mounting bracket 1326;

[0117] The mounting bracket 1326 is located on the opposite side of the indicator plate 1322 facing the back plate 1321.

[0118] The back panel 1321 is located on one side of the indicator panel 1322, and the mounting bracket 1326 is located on the opposite side of the indicator panel 1322 facing the back panel 1321. In this way, the mounting bracket 1326 and the back panel 1321 isolate and surround the indicator panel 1322 from both sides, which can prevent damage to both the indicator panel 1322 and the stored items.

[0119] Furthermore, in one specific embodiment provided in this application, the status indication structure 13 further includes an observation window and a transparent plug 133 that is fastened to the observation window.

[0120] In this specific implementation, the observation window is disposed on the mounting bracket 1326. The transparent plug 133 is fastened to the observation window to prevent foreign objects from entering.

[0121] This application also provides a status indication structure 13. Alternatively, the status indication structure 13 can be understood as a product that can be packaged and sold independently of the main part of the storage device 100. The main body of the storage device 100 consists of a first part 11 that engages with the device and a second part 12 that engages with the first part 11 to form a storage space. For simplicity, since the status indication structure 13 has already been fully explained in the aforementioned storage device 100, it will not be repeated here.

[0122] This application also provides a status indication structure 13 for indicating the status of the storage device 100, including:

[0123] Actuator 131;

[0124] Passive component 132 triggered by trigger 131;

[0125] When the trigger 131 is released from the state of being released from the passive component 132, it drives the reset component of the passive component 132 to reset.

[0126] The actuating element 131 is mainly used to provide a triggering force mechanically or mechanically. The actuating element 131 can be integrally formed or fixedly connected to the first part 11 of the device. The fixed connection can be welding, riveting or other assembly connection.

[0127] The passive component 132 is at least partially triggered by the trigger component 131.

[0128] The reset component is used to reset the passive component 132 when the trigger 131 is released from the state of being released from the passive component 132.

[0129] Compared to the status indication structure 13 that requires an energy storage unit, the storage device 100 with status indication provided in this application does not require an energy storage unit, which can improve the effective space carrying capacity of the storage device 100. In addition, the opening and closing status indication function will not fail due to the depletion of the energy storage unit, thus the opening and closing status indication is less likely to fail.

[0130] Furthermore, in one specific embodiment provided in this application, the passive component assembly 132 includes:

[0131] Back panel 1321;

[0132] Indicator plate 1322 moves relative to back plate 1321;

[0133] One end of the reset component is connected to the indicator plate 1322, and the other end is connected to the back plate 1321.

[0134] The back panel 1321 is used to isolate the indicator panel 1322, or to limit the movement space of the indicator panel 1322, preventing adverse effects when the indicator panel 1322 moves. It also prevents stored items from adversely affecting the indicator panel 1322. The back panel 1321 can be selected in a specific shape as needed; in one specific implementation provided in this application, it is a sheet or plate. For effective protection of the indicator panel 1322, hard metal or hard alloy can be used. Alternatively, the surface of the back panel 1321 can be covered with flexible rubber, leather, or other materials to protect the stored items.

[0135] The indicator plate 1322 moves relative to the back plate 1321. The indicator plate 1322 has different positions relative to the back plate 1321.

[0136] Furthermore, in one specific embodiment provided in this application, the indicator panel 1322 has an indicator area 1323;

[0137] The storage device 100 is also provided with an observation window so that the status changes of the storage device 100 can be observed through the indicator area 1323.

[0138] The indicator plate 1322 can be shaped as needed. In one implementation provided in this application, the indicator plate 1322 has a circular head and a rod-shaped arm. The circular head has a large area, making it easy to observe. The indicator area 1323 is located in the circular head. The rod-shaped arm is mainly used to drive the circular head. The rod-shaped arm is slender, which can reduce weight. The storage device 100 has an observation window. Changes in the indicator area 1323 can be observed through the observation window. In a specific implementation provided in this application, the color of the indicator area 1323 is different from the color of the back plate 1321. Thus, when the indicator area 1323 of the indicator plate 1322 moves, the color seen through the observation window will change, thereby indicating the change in the opening and closing state. The indicator area can also be marked with text, characters, patterns, etc., to distinguish it from the back plate.

[0139] Furthermore, in one specific embodiment provided in this application, the passive component assembly 132 further includes a limiting component 1325;

[0140] The limiting member 1325 is disposed between the back plate 1321 and the indicator plate 1322 to prevent the indicator plate 1322 from over-resetting.

[0141] The limiting member 1325 is used to prevent the indicator plate 1322 from over-resetting. In practice, the limiting member 1325 can be implemented as a stop. The limiting member 1325 only needs to ensure that the indicator plate 1322 returns to a preset position to prevent damage caused by over-limit.

[0142] Furthermore, in one specific embodiment provided in this application, the indicator plate 1322 is also provided with a tail fin;

[0143] When the trigger 131 abuts against the tail fin and overcomes the restoring force of the reset member, the indicator plate 1322 rotates relative to the back plate 1321.

[0144] When the trigger 131 disengages from the tail fin, the indicator 1322 is reset by the action of the reset element.

[0145] Furthermore, in one specific embodiment provided in this application, the indicator plate 1322 is also provided with a tail fin;

[0146] When the trigger 131 abuts against the tail fin and overcomes the restoring force of the reset member, the indicator plate 1322 translates relative to the back plate 1321.

[0147] When the trigger 131 disengages from the tail fin, the indicator 1322 is reset by the action of the reset element.

[0148] Furthermore, in one specific embodiment provided in this application, the tail fin is bent to form an abutment extension area 1324.

[0149] The indicator plate 1322 is also provided with a tail fin so that the trigger 131 can activate the indicator plate 1322. In one specific implementation provided in this application, the tail fin is bent to form an abutment extension area 1324. The process of bending the tail fin to form the abutment extension area 1324 is easy and low-cost to implement. When the abutment extension area 1324 is large, it is easily triggered by the trigger 131 and is less prone to failure.

[0150] Furthermore, in one specific embodiment provided in this application, the passive component assembly 132 further includes a mounting bracket 1326;

[0151] The mounting bracket 1326 is located on the opposite side of the indicator plate 1322 facing the back plate 1321.

[0152] The back panel 1321 is located on one side of the indicator panel 1322, and the mounting bracket 1326 is located on the opposite side of the indicator panel 1322 facing the back panel 1321. In this way, the mounting bracket 1326 and the back panel 1321 isolate and surround the indicator panel 1322 from both sides, which can prevent damage to both the indicator panel 1322 and the stored items.

[0153] Furthermore, in one specific embodiment provided in this application, the status indication structure 13 further includes an observation window and a transparent plug 133 that engages with the observation window. In a specific implementation of this application, the observation window is disposed on the mounting bracket 1326. The transparent plug 133 engages with the observation window to prevent foreign objects from entering.
