Description

Technical Field

[0001] This invention relates to the field of energy storage technology, specifically to a fire-fighting component and an energy storage module. Background Technology

[0002] Energy storage modules typically consist of a row of battery modules. To meet fire safety requirements, a fire suppression module is usually installed within the module. This module is often located at the end of the battery modules and monitors their temperature. When the temperature exceeds a set value, it releases fire suppression gas. When an energy storage module contains multiple rows of battery modules, the placement of the fire suppression module becomes a critical issue that needs to be addressed. Summary of the Invention

[0003] The purpose of this invention is to overcome the above-mentioned defects or problems in the prior art and to provide a fire protection component and an energy storage module that can ensure the fire protection function of the energy storage module when the energy storage module includes multiple battery modules, and the energy storage module is small in size and low in cost.

[0004] To achieve the above objectives, the present invention and its preferred embodiments employ the following technical solutions, but the embodiments are not limited to the following solutions:

[0005] Technical Solution 1 and its related embodiments involve a fire-fighting component for an energy storage module. The energy storage module includes a support wall extending along the Y-axis and at least two battery modules spaced apart along the Y-axis and supported on the support wall. Each battery module has a partition surface facing the other battery module, and a plug-in channel is formed between the two opposing partition surfaces. Adjacent battery modules are electrically connected. The fire-fighting component is characterized in that it is adapted to be inserted into the plug-in channel and includes: a mounting member comprising a connecting wall and a mounting wall fixedly connected to each other; the connecting wall being adapted to be supported on and locked to the support wall; the mounting wall being adapted to form a mounting channel between the connecting wall and the support wall when locked together, close to one of the partition surfaces; a gripping portion protruding from the end of the mounting wall away from the support wall, the gripping portion at least partially extending out of the plug-in channel; and a fire-fighting module fixedly connected to the mounting wall and located within the mounting channel, the distance between the end of the module away from the support wall and the entrance of the mounting channel being adapted to allow at least a portion of the electrical connection component to be inserted.

[0006] Based on technical solution one, there is also technical solution two. In technical solution two and its related embodiments, the gripping part is provided with a first tying hole that passes through along the Y-axis direction.

[0007] Based on technical solution one, there is also technical solution two. In technical solution two and its related embodiments, the connecting wall is provided with a non-detachable screw, and the projection of the non-detachable screw and the fire protection module along the Z-axis direction is offset from each other along the X-axis direction; the supporting wall is provided with a connecting hole suitable for the insertion of the non-detachable screw.

[0008] Based on technical solution three, there is also technical solution four. In technical solution four and its related embodiments, the support wall is provided with a positioning part extending along the Z-axis direction corresponding to the insertion channel, and the connecting wall is provided with a positioning hole that matches the positioning part.

[0009] Based on technical solution four, there is also technical solution five. In technical solution five and its related embodiments, there are at least two non-detachable screws and they are arranged at both ends of the connecting wall along the X-axis direction.

[0010] Based on technical solution five, there is also technical solution six. In technical solution six and its related embodiments, the mounting component is further provided with a reinforcing wall. The reinforcing wall is perpendicular to the X-axis direction and is fixedly connected to the mounting wall and the connecting wall. The projection of the fire protection module and the reinforcing wall along the X-axis direction at least partially overlaps.

[0011] Based on technical solution six, there is also technical solution seven. In technical solution seven and its related embodiments, the reinforcing wall and the gripping part are far apart from each other along the X-axis direction, and the end of the reinforcing wall away from the supporting wall is provided with a second tying hole; the length of the fire-fighting module along the Y-axis direction is greater than the length of the connecting wall along the Y-axis direction, and its length along the X-axis direction and Z-axis direction is less than the length of the mounting wall along the X-axis direction and Z-axis direction, respectively.

[0012] Based on technical solution one, there is also technical solution eight. In technical solution eight and its related embodiments, a through hole is opened in the middle of the mounting wall, and the fire protection module blocks the through hole on the side near the connecting wall.

[0013] Based on technical solution one, there is also technical solution nine. In technical solution nine and its related embodiments, the two ends of the fire-fighting component along the Y-axis direction are respectively adapted to abut against two opposing partition surfaces.

[0014] Technical solution ten and its related embodiments relate to an energy storage module, including a support wall extending along the Y-axis, at least two battery modules spaced apart along the Y-axis on the support wall, and a fire-fighting component as described in any one of technical solutions one to nine; each battery module has a partition surface facing another battery module, and an insertion channel is formed between the two opposing partition surfaces, and two adjacent battery modules are electrically connected, and the fire-fighting component is adapted to be inserted into the insertion channel.

[0015] As can be seen from the above description of the present invention and its preferred embodiments, compared with the prior art, the technical solution of the present invention and its preferred embodiments have the following beneficial effects due to the adoption of the following technical means:

[0016] In the first technical solution and its preferred embodiment, since the energy storage module includes at least two battery modules, if the fire protection module is placed at one end of each battery module along the Y-axis, the fire protection function of the fire protection module for multiple battery modules cannot be guaranteed. If the fire protection module is placed at both ends of each battery module along the Y-axis, the length of the energy storage module along the Y-axis needs to be longer, thus the volume of the energy storage module is large, and two fire protection modules will make the cost of the energy storage module higher.

[0017] To address this challenge, this technical solution places the fire suppression module within the gap between adjacent battery modules, aiming to enable one module to simultaneously provide fire suppression for two adjacent modules. This arrangement avoids increasing the length of the energy storage module along the Y-axis and reduces the number of fire suppression modules required. However, since the energy storage module cannot be too long, the gap between adjacent battery modules cannot be too large, meaning the width of the connection channel is limited. Furthermore, because copper busbars or cables are placed between adjacent battery modules, the fire suppression module must avoid interference with these components during installation. Fixing the fire suppression module in a confined space is also difficult, and removing it for maintenance becomes challenging. Therefore, the dilemma in this technical solution is how to place the fire suppression module within the narrow gap between battery modules and fix it relative to them while avoiding interference with electrical components, and how to facilitate convenient maintenance of the fire suppression module when needed.

[0018] Based on this, this technical solution installs the fire protection module on the mounting component, locks the mounting component to the supporting wall, and controls the dimensions of the fire protection module and the mounting component to solve the technical problems encountered when applying the above technical solution. Specifically, during installation, the fire-fighting module is first fixed to the mounting wall of the mounting component. At this point, the height of the fire-fighting component along the Z-axis is basically determined by the mounting wall, while the thickness of the fire-fighting component along the Y-axis is basically determined by the thickness of the fire-fighting module or the thickness of the connecting wall. The fire-fighting component is inserted into the insertion channel by holding the grip, and the connecting wall and the supporting wall of the mounting component are locked together. After the fire-fighting component is installed, at least part of the electrical connection component is placed in the mounting channel. The fire-fighting module is located between the connecting wall and the electrical connection component along the Z-axis, and the electrical connection component is located between the mounting wall and the contact surface of a battery module along the Y-axis. Therefore, the electrical connection component and the fire-fighting component do not interfere with each other in the insertion channel. When it is necessary to disassemble the fire-fighting module, the electrical connection component is first disassembled to release the locking of the connecting wall and the supporting wall. Then, the part of the grip that extends out of the insertion channel is grasped by hand to remove the mounting component, and the fire-fighting module can be removed.

[0019] It is evident that by adopting this technical solution, the fire protection module can be installed and disassembled within the narrow gap between adjacent battery modules, and the fire protection module and its mounting components do not interfere with the electrical connection components, thus achieving full utilization of space. Therefore, the fire protection function of the energy storage module can be guaranteed even when the energy storage module includes multiple battery modules, and the energy storage module is small in size and low in cost.

[0020] In technical solution two and its preferred embodiments, when the fire protection module implements the fire protection function, it needs to collect fire protection information (such as temperature, pressure, etc.) of each battery module and determine whether to release fire protection substances (such as fire protection gas) based on the fire protection information. Each battery module includes multiple cells, and the sampling line collects the fire protection information of each cell. The sampling line is connected to the fire protection module. If the sampling line falls into the gap between the battery modules, it may cause false triggering of the fire protection threshold or make it difficult to remove. In this technical solution, a first wire-tying hole is provided on the grip part to fix the sampling line, thereby preventing the sampling line from falling into the plug-in channel, which is conducive to the stable operation of the energy storage module and facilitates subsequent maintenance. Moreover, since the grip part is far away from the support wall, the operation of fixing the sampling line is convenient.

[0021] In technical solution three and its preferred embodiments, the design of the non-loosening screws and connecting holes facilitates the locking operation of the connecting wall and the supporting wall, and avoids the inconvenience of installation caused by easily loosened screws falling off. This advantage is particularly prominent when the length of the insertion channel along the Y-axis is small.

[0022] In the fourth technical solution and its preferred embodiment, the positioning part and positioning hole can realize the pre-positioning of the connecting wall, which further facilitates the installation of the mounting part. This advantage is particularly prominent when the length of the insertion channel along the Y-axis is small.

[0023] In technical solution five and its preferred embodiments, there are at least two non-detachable screws arranged at both ends of the connecting wall along the X-axis direction, which facilitates disassembly and assembly, and ensures structural stability after locking.

[0024] In technical solution six and its preferred embodiments, the reinforcement wall increases the strength of the mounting component, and the projection of the fire-fighting module and the reinforcement wall along the X-axis direction at least partially overlaps, so that the fire-fighting component can maintain a small thickness along the Y-axis direction, which is beneficial to the installation of the fire-fighting component.

[0025] In technical solution seven and its preferred embodiments, a second tying hole is provided at the end of the reinforcing wall away from the supporting wall, which further facilitates the fixing of the sampling line; the length of the fire-fighting module along the Y-axis is greater than the length of the connecting wall along the Y-axis, and its length along the X-axis and Z-axis is less than the length of the mounting wall along the X-axis and Z-axis, respectively. Therefore, the thickness of the fire-fighting component along the Y-axis is mainly the thickness of the fire-fighting module along the Y-axis, and the length along the X-axis and Z-axis is mainly the length of the mounting wall along the X-axis and Z-axis. The overall size of the fire-fighting component is minimized as much as possible, making installation more convenient.

[0026] In technical solution eight and its preferred embodiment, a through hole is opened in the middle of the mounting wall, which helps to reduce the weight of the fire-fighting component, thereby reducing the weight of the energy storage module when applied to the energy storage module; the fire-fighting module blocks the side of the through hole near the connecting wall, so the side of the through hole away from the connecting wall can be grabbed in practical applications.

[0027] In technical solution nine and its preferred embodiments, the two ends of the fire-fighting component along the Y-axis direction are respectively adapted to abut against two opposing partition surfaces, which not only makes full use of the space in the insertion channel, but also limits the fire-fighting component along the Y-axis direction.

[0028] Technical solution ten has the technical advantages of any one of technical solutions one through nine. Attached Figure Description

Detailed Implementation

[0038] 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 preferred embodiments of the present invention and should not be considered as excluding other embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0039] Unless otherwise expressly defined, the use of terms such as "first," "second," or "third" in the claims, description, and accompanying drawings of this invention is for distinguishing different objects and not for describing a specific order.

[0040] Unless otherwise expressly defined, in the claims, description, and accompanying drawings of this invention, the use of directional terms such as "center," "lateral," "longitudinal," "horizontal," "vertical," "top," "bottom," "inner," "outer," "upper," "lower," "front," "rear," "left," "right," "clockwise," and "counterclockwise" to indicate orientation or positional relationships is based on the orientation and positional relationships shown in the accompanying drawings and is only for the convenience of describing the invention and simplifying the description, and is not intended to 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 limiting the specific scope of protection of this invention.

[0041] Unless otherwise expressly defined, the terms "fixed connection" or "fixed connection" used in the claims, description and drawings of this invention should be interpreted broadly to refer to any connection in which there is no displacement or relative rotation relationship between the two parties, including non-removable fixed connection, detachable fixed connection, integral connection and fixed connection by other means or components.

[0042] In the claims, description and accompanying drawings of this invention, the terms "comprising," "having," and variations thereof are used to mean "including but not limited to."

[0043] In the claims and the description other than the embodiments, the terms "X-axis direction," "Y-axis direction," and "Z-axis direction" only refer to a feature having one of the aforementioned directions being perpendicular to a feature having another direction, and do not require that they be implemented according to the "X-axis direction," "Y-axis direction," and "Z-axis direction" described in the embodiments. In the embodiments, the X-axis direction is perpendicular to both the Y-axis direction and the Z-axis direction. The X-axis direction can be divided into left and right, the Y-axis direction into front and back, and the Z-axis direction into up and down.

[0044] See Figure 1 , Figure 1 An energy storage module 100 is shown, including a base 10, a battery module 20, and a fire-fighting component. The length of the energy storage module 100 is the Y-axis (front-to-back direction), the width is the X-axis (left-to-right direction), and the height is the Z-axis (up-down direction).

[0045] See Figure 2-5 The base 10 has a support wall 11 extending along the Y-axis. There are at least two battery modules 20, each supported on the support wall 11 and spaced apart along the Y-axis. Each battery module 20 has a partition surface 21 facing the other battery module 20, forming a connection channel 01 between two opposing partition surfaces 21. Adjacent battery modules 20 are electrically connected via an electrical connection assembly, which can be a copper busbar or a cable. In this embodiment, adjacent battery modules 20 are electrically connected via a copper busbar 30. In practical applications, the partition surface 21 is formed by the end plate of the battery module 20, and the copper busbar 30 extends at least partially along the X-axis.

[0046] Since the energy storage module 100 includes at least two battery modules 20, if the fire protection module 50 is placed at one end of each battery module 20 along the Y-axis, the fire protection function of the fire protection module 50 for multiple battery modules 20 cannot be guaranteed. If the fire protection module 50 is placed at both ends of each battery module 20 along the Y-axis, the length of the energy storage module 100 along the Y-axis needs to be longer, resulting in a large volume of the energy storage module 100. Furthermore, two fire protection modules 50 would increase the cost of the energy storage module 100.

[0047] Faced with this dilemma, this embodiment places the fire-fighting module 50 within the gap between adjacent battery modules 20, so that one fire-fighting module 50 can simultaneously provide fire-fighting functionality for two adjacent battery modules 20. This arrangement avoids increasing the length of the energy storage module 100 along the Y-axis and reduces the number of fire-fighting modules 50. However, since the length of the energy storage module 100 cannot be too long, the gap between adjacent battery modules 20 will not be too large, meaning the width of the insertion channel 01 will not be very large. Furthermore, since electrical connection components are placed between adjacent battery modules 20, using the copper busbar 30 as an example in this embodiment, the installation of the fire-fighting module 50 becomes even more challenging. The fire-fighting module 50 must also avoid interfering with the copper busbar 30 during installation. Fixing the fire-fighting module 50 in a confined space is also difficult. Similarly, removing the fire-fighting module 50 when maintenance is required will also be a challenge. Therefore, the dilemma faced by this technical solution is how to place the fire protection module 50 within the narrow gap of the battery module 20 and fix it relative to the battery module 20, while avoiding interference with the copper busbar 30, and how to conveniently maintain the fire protection module 50 when it needs maintenance.

[0048] In this embodiment, the structure of the support wall 11 was first improved, see [reference]. Figure 5 The support wall 11 is provided with two connecting holes 12 along the X-axis and two positioning parts 13 extending along the Z-axis in relation to the insertion channel 01. Of course, the number of connecting holes 12 and positioning parts 13 can be more or less, and the two positioning parts 13 are located between the two connecting holes 12. In this embodiment, the positioning part 13 is mainly in the form of a positioning pin.

[0049] Next, see Figure 2-6 In this embodiment, the fire protection module 50 is installed on the mounting component 40, the mounting component 40 is locked to the support wall 11, and the dimensions of the fire protection module 50 and the mounting component 40 are controlled to solve the technical problems encountered when applying the above technical solution.

[0050] Specifically, the fire protection component is adapted to be inserted into the insertion channel 01, including the mounting piece 40 and the fire protection module 50 fixedly connected to each other.

[0051] See Figure 4 and Figure 6 The mounting component 40 includes a connecting wall 41, a mounting wall 42, and a reinforcing wall 43 fixedly connected to each other. The connecting wall 41 is adapted to be supported on and locked to the supporting wall 11. The mounting wall 42 is adapted to form a mounting channel 02 between the connecting wall 41 and the supporting wall 11 when the connecting wall 41 is locked to the supporting wall 11, close to one of the partition surfaces 21 and between the connecting wall 41 and the other partition surface 21. The end of the mounting wall 42 away from the supporting wall 11 ( Figure 6The top of the mounting wall 42 has a protruding gripping part 421, which at least partially extends out of the insertion channel 01. A through hole 422 is provided in the middle of the mounting wall 42. Figure 6 In the diagram, the through hole 422 is rectangular, with its length along the Z-axis and its width along the X-axis. The reinforcing wall 43 is perpendicular to the X-axis and is fixedly connected to both the mounting wall 42 and the connecting wall 41. Figure 6 In the middle, the connecting wall 41 extends along the X-axis and is perpendicular to the Z-axis. The length of the connecting wall 41 along the X-axis is greater than the length of the mounting wall 42 along the X-axis. The reinforcing wall 43 is located on one side of the mounting wall 42 along the X-axis. The bottom end of the reinforcing wall 43 is integrated with the connecting wall 41, and the side of the reinforcing wall 43 is integrated with the mounting wall 42.

[0052] The reinforcing wall 43 and the gripping part 421 are spaced apart from each other along the X-axis. The gripping part 421 has a first tying hole 4211 that extends along the Y-axis, and the reinforcing wall 43 has a second tying hole 431 at the end away from the supporting wall 11. The connecting wall 41 is provided with a captive screw 411, and the captive screw 411 and the projection of the fire module 50 along the Z-axis are offset from each other along the X-axis. There are at least two captive screws 411 and they are arranged at both ends of the connecting wall 41 along the X-axis. Figure 6 There are two captive screws 411, which correspond to and are suitable for insertion into the corresponding connecting holes 12. The connecting wall 41 is provided with positioning holes 412 that are adapted to the positioning part 13.

[0053] The fire protection module 50 is fixed to the mounting wall 42 and located within the mounting channel 02, with its end away from the supporting wall 11 connected to the entrance of the mounting channel 02. Figure 4 The spacing between the tops of the components is suitable for inserting at least a portion of the copper busbar 30. The fire protection module 50 seals the through-hole 422 on the side near the connecting wall 41. Figure 6 In the middle, the fire protection module 50 is secured to the mounting wall 42 with screws, and the lower part of the fire protection module blocks the through hole 422. The projections of the fire protection module 50 and the reinforcing wall 43 along the X-axis direction at least partially overlap.

[0054] Figure 6 In the process, the length of the fire protection module 50 along the Y-axis is greater than the length of the connecting wall 41 along the Y-axis, and its lengths along the X-axis and Z-axis are less than the lengths of the mounting wall 42 along the X-axis and Z-axis, respectively.

[0055] The installation process is as follows:

[0056] First, fix the fire module 50 to the mounting wall 42 of the mounting component 40. At this time, the height of the fire component along the Z-axis is basically determined by the mounting wall 42, and the thickness of the fire component along the Y-axis is basically determined by the thickness of the fire module 50. Hold the grip part 421 and insert the fire component into the insertion channel 01, so that the positioning part 13 of the support wall 11 is inserted into the positioning hole 412 of the connecting wall 41. The non-removable screw 411 of the connecting wall 41 is inserted into the connecting hole 12 of the support wall 11. Tighten the non-removable screw 411 to lock the connecting wall 41 and the support wall 11.

[0057] After the fire protection components are installed, the electrical connection components are installed. In this embodiment, copper busbar 30 is used as an example. The part of copper busbar 30 extending along the X-axis is placed in the installation channel 02. The fire protection module 50 is located between the connecting wall 41 and the copper busbar 30 along the Z-axis. The copper busbar 30 is located between the mounting wall 42 and the contact surface of a battery module 20 along the Y-axis. Therefore, the copper busbar 30 and the fire protection components do not interfere with each other in the insertion channel 01. Then, the sampling line of the fire protection module 50 is laid above the battery module 20 and fixed through the first wire binding hole 4211 and the second wire binding hole 431. At this time, the two ends of the fire protection components along the Y-axis are respectively suitable for abutting against two opposite partition surfaces 21. Specifically, the fire protection module 50 and the screws of the fire protection module 50 and the mounting wall 42 abut against two opposite partition surfaces 21 respectively.

[0058] When it is necessary to disassemble the fire protection module 50, first disassemble the copper busbar 30, loosen the non-removable screw 411 to release the locking of the connecting wall 41 and the supporting wall 11, and then use your hand to grab the part of the gripping part 421 that extends out of the insertion channel 01 to remove the mounting part 40, and then the fire protection module 50 can be removed.

[0059] In this embodiment, an energy storage module 100 includes two battery modules 20 and a fire protection module 50. However, it should be understood that when the energy storage module 100 includes a larger number of battery modules 20, the number of fire protection modules 50 should also be increased accordingly.

[0060] As can be seen, in this embodiment, the length of the fire-fighting component along the X-axis is mainly the length of the connecting wall 41 along the X-axis, the thickness of the fire-fighting component along the Y-axis is mainly the thickness of the fire-fighting module 50 along the Y-axis, and the length along the Z-axis is mainly the length of the mounting wall 42 along the Z-axis. The overall size of the fire-fighting component is minimized as much as possible, making installation more convenient.

[0061] This embodiment allows for the installation and removal of the fire-fighting module 50 within the narrow gap between adjacent battery modules 20, and ensures that neither the fire-fighting module 50 nor the mounting component 40 interferes with the copper busbar 30, thus maximizing space utilization. Therefore, it guarantees the fire-fighting function of the energy storage module 100 even when it includes multiple battery modules 20, and the energy storage module 100 is small in size and low in cost. The two ends of the fire-fighting component along the Y-axis are respectively adapted to abut against two opposing partition surfaces 21, not only maximizing the space within the insertion channel 01 but also limiting the movement of the fire-fighting component along the Y-axis.

[0062] When the fire protection module 50 implements the fire protection function, it needs to collect the fire protection information of each battery module 20 and determine whether to release fire protection substances (such as fire protection gas) based on the fire protection information (such as temperature, pressure, etc.). Each battery module 20 includes multiple cells. The sampling line collects the fire protection information of each cell and is connected to the fire protection module 50. If the sampling line falls into the gap between the battery modules 20, it may cause false triggering of the fire protection threshold or make it difficult to remove. In this embodiment, a first wire tying hole 4211 is provided on the grip part 421 and a second wire tying hole 431 is provided on the reinforcing wall 43 to fix the sampling line, thereby preventing the sampling line from falling into the plug-in channel 01. This is beneficial to the stable operation of the energy storage module 100 and facilitates subsequent maintenance. Since the first wire tying hole 4211 and the second wire tying hole 431 are both far away from the support wall 11, the operation of fixing the sampling line is convenient.

[0063] The inclusion of the captive screws 411 and the connecting holes 12 facilitates the locking operation of the connecting wall 41 and the supporting wall 11, and avoids installation inconvenience caused by screws falling out. The positioning part 13 and the positioning holes 412 enable pre-positioning of the connecting wall 41, further facilitating the installation of the mounting component 40. This advantage is particularly prominent when the length of the insertion channel 01 along the Y-axis is short. The presence of at least two captive screws 411 at both ends of the connecting wall 41 along the X-axis facilitates disassembly and assembly, and ensures structural stability after locking. This advantage is particularly prominent when the length of the insertion channel 01 along the Y-axis is short.

[0064] The reinforcement wall 43 increases the strength of the mounting component 40. The projection of the fire-fighting module 50 and the reinforcement wall 43 along the X-axis direction at least partially overlaps, allowing the fire-fighting component to maintain a smaller thickness along the Y-axis direction, which is beneficial for the installation of the fire-fighting component. The through hole 422 in the middle of the mounting wall 42 helps to reduce the weight of the fire-fighting component, thereby reducing the weight of the energy storage module 100 when applied to it. The fire-fighting module 50 blocks the side of the through hole 422 near the connecting wall 41, so the side of the through hole 422 away from the connecting wall 41 can be gripped in practical applications.

[0065] The foregoing description of the specifications and embodiments is intended to explain the scope of protection of this invention, but does not constitute a limitation on the scope of protection of this invention. Modifications, equivalent substitutions, or other improvements to the embodiments of this invention or a portion thereof that can be obtained by those skilled in the art through logical analysis, reasoning, or limited experimentation, based on the teachings of this invention or the foregoing embodiments, in conjunction with common knowledge, general technical knowledge, and / or existing technology, should all be included within the scope of protection of this invention.
